Description
FIELD OF THE INVENTION
[0001] The present invention relates to a joint-sealing element for
sealing joints on a building construction and/or on a building
structure, especially for sealing against sound and smoke and if
necessary against fire. In particular, the invention relates to
acoustic, smokeproof and/or fireproof sealing of connecting joints
in drywalls, especially of expansion joints.
BACKGROUND OF THE INVENTION
[0002] Connecting joints are usually formed when different building
parts meet. Connecting joints are found in the region of connection
to the ceiling of a building level, to the floor and to massive
walls. Due to weight loading and/or thermal influences, the ceiling
in buildings may be forced upward or downward. To prevent damage to
the drywall, the upper connecting joint in this case is made as an
expansion joint. Thus joints for creating discontinuities in
building parts in order to prevent stress cracking are known as
expansion joints. The ceiling profile is made in such a way that a
relative movement between ceiling profile and the vertical wall
components is possible.
[0003] In general, a channel profile constituting part of the
studwork is fastened to the connecting building parts. The gypsum
boards themselves are attached at a well-defined spacing to the
connecting building part. Usually sealing of the system is provided
in the gap between gypsum board and ceiling. For this purpose,
either a suitable sealing compound is introduced or else the gap is
filled with mineral wool and provided at the surface with a sealing
layer. In both cases, the material present in the joint presents
relatively strong resistance to movement, with the consequence that
comparatively large joint widths are necessary in order to achieve
adequate movement absorption.
[0004] In particular, sealing of the gap with sealing compound has
some disadvantages. The application of a conventional sealing
compound in order to achieve sufficient sealing of the gap is
impacted very severely by long curing times, depending on curing
temperature as well as dosing of the correct quantity. It is
particularly laborious, and in the course of time the sealing tends
to crack when overloaded. Furthermore, sealing can be performed
only after the gypsum boards have been mounted, and it requires
access to the finished drywall from both sides. Furthermore, this
procedure is error-prone, since the user himself or herself must
dose the correct quantity of material in order to seal the gap
adequately. Above and beyond this, the drywall builder must make
the width of the joint correspond to the material and expansion
properties of the sealing compound. During installation of the
sealing compound, nothing but the joint can be filled. During
expansion of the gap, it must be ensured that the sealing compound
adheres sufficiently strongly to the underlying surface and that it
is able to absorb the tensile forces that develop. Frequently this
not the case, and the danger exists that the sealing compound will
become detached from the underlying surface or that the sealing
compound itself will be overloaded and tear. In the case of a
narrower gap, the sealing compound can be compressed to only a
limited extent, because of its material properties, and the danger
exists that it will be forced out of the gap if the joint is
incorrectly dimensioned. Due to the limited expansion and
compression capability of the sealing compound (max. +1-25%), it is
very important to ensure adequately large dimensioning of the
spacing between gypsum board and ceiling. This is frequently
underestimated, and so adequate imperviousness often cannot be
guaranteed during use of customary sealing compounds.
[0005] Some further approaches exist for sealing of joints,
especially joint cords or joint sprays, which to some extent suffer
from the same disadvantages as have been described for sealing
compounds. In particular, a joint-sealing element is known from
U.S. Pat. No. 8,584,415 B2, but it consists of a hollow rubber
profile and so is characterized by poor compressibility and thus
deformability. Such hollow rubber profiles are compressed in upward
direction during installation with the gypsum board, which among
other problems may lead to poor sealing at the abutting
surface.
[0006] The object of the invention is therefore to provide a
joint-sealing element that avoids the disadvantages of the known
materials, that in particular is easier and safer to use,
simplifies the mounting of further building parts, ensures good
sealing as soon as it is applied and ensures excellent
imperviousness with maximum absorption of movement. In particular,
it is an object of the present invention to provide a joint-sealing
element that can be readily compressed and deformed, and with which
improved evening out of irregularities, improved installation, e.g.
simple laying even around a corner, and improved sealing, e.g. when
several joint-sealing elements are abutted against one another, can
be achieved.
[0007] A further object of the present invention is to provide a
method for sealing a joint that can be accomplished simply, is
reliable with little work effort and leads without defects to
sealing of a joint between two juxtaposed building parts of a
building construction and/or of a building structure.
[0008] Yet another object of the present invention is to provide an
arrangement that, in the event of fire, permits better sealing of
the joint between two building parts, especially between a drywall
and a connecting building part, such as a wall, a ceiling or a
floor, and thus provides better and durable sealing against sound
and/or smoke and if necessary better and durable fire protection,
and can be mounted reliably and free of defects with little work
effort.
[0009] This and further objects that will become apparent from the
description of the invention hereinafter are achieved by the
present invention, as described in the independent claims. The
dependent claims relate to preferred embodiments.

DETAILED DESCRIPTION OF THE INVENTION
[0023] The following terms are used within the scope of the present
invention:
[0024] Within the scope of the present invention, the term
"geometry / geometries" comprises various cross-section types and
cross-section shapes. This means that the sealing profile in
particular may have different cross-section types and cross-section
shapes. Cross-section types are understood among other
possibilities as round profile (round cross section), oval profile
(oval cross section), wedge profile (wedge cross section),
polygonal profile (polygonal cross section), especially square
profile (square cross section), rectangular profile (rectangular
cross section), parallelogram profile (cross section in the shape
of a parallelogram), triangular profile (triangular cross section),
Christmas-tree profile (Christmas-tree-shaped cross section),
semicircular profile (semicircular cross section), etc., among
others. Cross-sectional shapes are understood as solid profile and
hollow profile, wherein solid profile means that the sealing
profile consists completely of sealing material while the hollow
profile means that the sealing profile consists only partly of
sealing material.
[0025] Within the scope of the present invention, the term
"deformable" means that irregularities in the building part,
against which the sealing profile is pressed, can be evened out. In
this connection, "plastically deformable" means that the sealing
profile is deformable and no longer returns to its original shape
after deformation. Analogously, "elastically deformable" means that
the sealing profile is deformable and returns to its original shape
after deformation, i.e. the material can be deformed reversibly to
a certain extent.
[0026] The terms "exhibit", "with" and "have" are intended to be
inclusive and mean that elements other than those cited may also be
meant.
[0027] Within the scope of the present invention, the term
"intumescence" means that, under the effect of heat, for example in
the event of a fire, the material swells and forms an insulating
layer of flame-retardant material, i.e. intumesces.
[0028] Within the scope of the present invention, "slow-burning
foam" is understood as a foam that offers no possibility of fire
propagation due to the foam, is not spontaneously flammable and
also does not drip.
[0029] "Positioned in the lower region of the joint" means that the
sealing profile is disposed, especially laterally, on an upper end
edge of the first building part, preferably a drywall.
[0030] As used within the scope of the present invention, the
singular forms "one", "a" and "an" also include the corresponding
plural forms, unless something different can be inferred
unambiguously from the relationship. Thus, for example, the term
"one" is intended to mean "one or more" or "at least one", unless
otherwise indicated.
[0031] In one aspect, the present invention relates to a
joint-sealing element for sealing a joint on a building
construction and/or on a building structure, especially for sealing
a joint between a first building part and a second building part,
wherein the joint-sealing element comprises a carrier element and a
sealing profile disposed on this carrier element and is
characterized in that the disposed sealing profile has a
predetermined geometry.
[0032] In a further aspect, the present invention relates to a
method for sealing a joint between two juxtaposed building parts of
a building construction and/or of a building structure with at
least one first building part, one second building part and the
inventive joint-sealing element.
[0033] In a further aspect, the present invention relates to a
sealing arrangement for sealing a joint between two juxtaposed
building parts of a building construction and/or of a building
structure with at least one first building part, one second
building part and the inventive joint-sealing element, wherein the
sealing profile is positioned in the lower region of the joint and
is configured to seal the joint from the outside.
[0034] It has been discovered that the inventive joint-sealing
element is particularly suitable for safely sealing, in simple
manner, a building-structure joint between two adjacent building
parts, especially against sound and/or smoke and if necessary also
against fire. For the joint-sealing element to be able to fulfill
its function, the sealing profile of the joint-sealing element must
have a predetermined geometry. Furthermore, the joint-sealing
element must be positioned in the lower region of the joint and be
configured such that it can seal the joint from the outside.
[0035] Therefore, it is an objective of the present invention to
describe the joint-sealing element. In particular, it is an
objective of the present invention to describe the geometry of the
sealing profile in detail. Furthermore, it is an objective of the
present invention to describe the positioning of the joint-sealing
element, especially a sealing arrangement as well as a method for
sealing a joint between two juxtaposed building parts of a building
construction and/or of a building structure with at least one
building part, one second building part.
[0036] The inventive joint-sealing element for sealing a joint on a
building construction and/or on a building structure, especially
for sealing a joint between a first building part and a second
building part, wherein the joint-sealing element comprises a
carrier element and a sealing profile disposed on this carrier
element, is characterized in that the disposed sealing profile has
a predetermined geometry. As already mentioned hereinabove,
geometries within the scope of the present invention comprise
various cross-section types and cross-section shapes.
[0037] Preferred cross-section types of the sealing profile of the
joint-sealing element according to the present invention are solid
profiles and if necessary hollow profiles, wherein the hollow
profile may be a closed or open hollow profile, preferably with a
wall thickness of >2 mm. Solid profiles and hollow profiles with
large profile wall thicknesses have the advantage that
automatically no gaps develop at the abutting surface between two
sealing profiles in contact with one another. It is particularly
preferred for the sealing profile to have a solid profile.
[0038] Preferred cross-section shapes of the sealing profile of the
joint-sealing element according to the present invention are round
profile, oval profile, wedge profile, polygonal profile, especially
rectangular profile, square profile, parallelogram profile,
triangular profile, Christmas-tree profile and semicircular
profile. Round profile, oval profile and wedge profile are
particularly preferred, but round profile is the most preferred.
Nevertheless, other or mixed cross-section shapes are also
conceivable and possible, as long as the joint-sealing element is
adjacent to both building parts after installation of the sealing
profile and is able to close the joint that is present between the
building parts.
[0039] In a preferred embodiment of the inventive joint-sealing
element, the sealing profile has a round profile.
[0040] In a further preferred embodiment of the inventive
joint-sealing element, the sealing profile has a wedge profile.
[0041] In a particularly preferred embodiment of the inventive
joint-sealing element, the sealing profile has a solid profile and
a round profile.
[0042] In a further particularly preferred embodiment of the
inventive joint-sealing element, the sealing profile has a solid
profile and a wedge profile.
[0043] The geometry of the sealing profile may be prefabricated,
for example by well-defined cutting to size, extrusion or pressing
of suitable sealing material or can be manufactured directly from
flat material, for example by means of folding or rolling from a
flat starting material, for example from fabric, especially from an
incombustible material, such as inorganic fibers, for example glass
fibers, a nonwoven fabric or the like. The manufacture of such
cross-section types and cross-section shapes is known to the person
skilled in the art. Preferably the geometry of the sealing profile
is prefabricated by well-defined cutting to size or extrusion.
[0044] The inventive sealing profile may consist of one piece made
from one material or of multiple parts made from several materials
and, for example, may exist as a layered body. In alternative
embodiments, the outer region and the inner region of a sealing
profile may define separate regions of the sealing profile, which
may have different cross-section shapes and/or cross-section types
and/or may consist of different materials.
[0045] According to the invention, the sealing profile consists of
a deformable material. This material may be either plastically or
elastically deformable. In particular, the sealing profile consists
at least partly, preferably completely of a material that is
resilient after compression, such as foam, sponge rubber, cellular
rubber or the like. The inventive sealing profile preferably
consists of a soft foam that is resilient after compression. Common
foams such as polyethylene and polyurethane foams or cellular
rubber can be mentioned as foam material. This foam may be an
open-celled foam with very low air passage resistance, or else an
approximately closed-celled foam with extremely low air
permeability values. Even foams with air permeability values lying
between the two extreme cases mentioned in the foregoing may be
used within the scope of the present invention. The foam may be
impregnated with an impregnating agent that increases the sealing
properties of the foam. In order to achieve imperviousness to
smoke, at least the outer surface of the sealing profile must be of
closed-pore nature. Alternatively, an open-celled sealing profile
with a cover layer or jacket, for example of a film, especially
plastic film, may be provided. Preferably the sealing profile
consists of an open-celled polyurethane foam or of a cellular
rubber.
[0046] It has proved advantageous when the sealing profile consists
of a slow-burning foam, such a cellular rubber or polyurethane
foam, for example. In the case of a slow-burning foam, there is no
possibility that fire will be propagated by the foam. Spontaneous
inflammation is ruled out by the above-mentioned foam-type starting
materials. It is also advantageous that no dripping occurs in the
event of fire. A slow-burning foam should still have at least 20%,
still at least 25%, preferably still at least 30%, between 20% and
60%, between 20% and 40%, preferably between 25% and 30% of its
initial volume in a temperature range between 500.degree. C. and
800.degree. C. Furthermore, a slow-burning foam should still have
at least 10%, at least 20%, preferably still at least 30%, between
10% and 40%, between 10% and 30%, preferably between 15% and 20% of
its initial mass in a temperature range between 500.degree. C. and
800.degree. C.
[0047] Furthermore, the material may contain appropriate additives
if fire protection properties such as intumescence, for example,
are desired. Under the effect of heat, such as in the event of
fire, the material swells and forms an insulating layer of
flame-retardant material. The formation of a voluminous insulating
layer, namely an ash layer, may take place due to the chemical
reaction of a mixture of compounds that are appropriately matched
to one another and that react with one another under the effect of
heat. Such systems are known to the person skilled in the art as
chemical intumescence, and they may be used according to the
invention.
[0048] Alternatively, the voluminous insulating layer may be formed
by swelling of an individual compound, which releases gases under
the effect of heat, even though no chemical reaction has occurred
between two compounds. Such systems are known to the person skilled
in the art as physical intumescence, and they may also be used
according to the invention. According to the invention, the two
systems may be used respectively alone or together as a
combination. Preferably the sealing profile comprises an
intumescent material.
[0049] In a preferred embodiment of the inventive joint-sealing
element, the sealing profile consists of an open-celled foam.
[0050] In a further preferred embodiment of the inventive
joint-sealing element, the sealing profile consists of a
closed-celled foam.
[0051] In a particularly preferred embodiment of the inventive
joint-sealing element, the sealing profile consists of an
open-celled polyurethane foam.
[0052] In a further particularly preferred embodiment of the
inventive joint-sealing element, the sealing profile consists of a
cellular rubber.
[0053] The carrier element of the inventive joint-sealing element
may consist of a deformable material, which may be the same as that
of the sealing profile, of a film, such as a plastic film, of a
fabric, especially of a noncombustible material, such as inorganic
fibers, for example glass fibers, a nonwoven or the like.
Preferably the carrier element consists of a plastic, of a plastic
film, of a foam, of a fabric, of a nonwoven, of a metal, of a
composite material or the like, preferably of a plastic film or of
a foam. Most preferably, the carrier element consists of a
film.
[0054] The carrier element may be made in one piece from one
material or in multiple pieces, even from different materials.
Preferably the carrier element is made in one piece.
[0055] The inventive joint-sealing element may be made in one piece
from one material or in multiple pieces, even from different
materials. Preferably the joint-sealing element consists of several
units/materials. Particularly preferably, the sealing profile
consists of deformable material and the carrier element of a film
or fabric.
[0056] In one embodiment of the inventive joint-sealing element,
the sealing profile is firmly surrounded at least over part of its
circumference by a covering layer or jacket, for example of a film,
especially plastic film. Thus an open-celled foam material may be
used for the sealing profile.
[0057] In one embodiment of the inventive joint-sealing element,
the sealing profile is firmly bonded at least over part of its
circumference with the carrier element. Hereby a firm connection is
created between the carrier element and the sealing profile, so
that even if the fastening region is exposed to strong stress and
strain and the sealing profile becomes partly detached from the
carrier element, complete separation of the sealing profile from
the carrier element is prevented.
[0058] In a further embodiment of the inventive joint-sealing
element, the sealing profile is firmly bonded over its entire
circumference with the carrier element. On the one hand, optimum
and durable fastening of the sealing profile to the carrier element
is achieved hereby, making separation of the sealing profile from
the carrier element almost impossible. On the other hand, when the
carrier layer is impermeable to smoke gas, an open-celled foam
material may be used for the sealing profile.
[0059] Preferably the sealing profile is disposed on the carrier
element; more preferably the sealing profile is positioned on the
outer periphery of the carrier element.
[0060] The joint-sealing element of the present invention,
especially the carrier element of the joint-sealing element,
preferably has at least one fastening region oriented in the
direction of the longitudinal extent of the joint for fastening of
the joint-sealing element on a construction element of the building
construction and/or of the building structure disposed peripherally
on the joint. Preferably the at least one fastening region of the
joint-sealing element is provided with an adhesive layer.
[0061] The adhesive layer of the inventive joint-sealing element
may be produced in the form of an adhesive layer, especially a
self-adhesive layer, in the form of interlocking or frictionally
acting means, such as suitable profiled shapes or putty material or
by means of a separately applicable adhesive or the like. Synthetic
adhesives such as acrylate adhesives or hot-melt adhesives may be
used in the present invention, although silicone-base adhesives are
also conceivable. Preferably the adhesive layer of the
joint-sealing element is a self-adhesive layer.
[0062] Fastening of the joint-sealing element to the first building
part may be achieved by fastening means, for example in the form of
the just-mentioned adhesive layer, especially a self-adhesive
layer, in the form of interlocking or frictionally acting means,
such as suitable profiled shapes or putty material, by means of a
separately applicable adhesive or the like. Fastening may comprise
adhesives, screws, dowels, clamps and nails. Preferably the
joint-sealing element is fastened to the first building part by
means of a self-adhesive layer. Fastening of the inventive
joint-sealing element may be applied over an area or only at
spots.
[0063] The inventive method for sealing a joint between two
juxtaposed building parts of a building construction and/or of a
building structure with at least one first building part, one
second building part and the inventive joint-sealing element is
characterized in that, in a first step, the joint-sealing element
is positioned and fastened on an end edge of the first building
part, especially a drywall, preferably a gypsum board and, in a
second step, is positioned together with this building part on the
second building part. Preferably the first step comprises fastening
by adhesives, screws, dowels, clamps and nails. In particular, the
carrier element can be fastened flush on the upper, inwardly
facing, horizontal end edge of a gypsum board.
[0064] The dimension and the materials of the joint-sealing element
are chosen to correspond to the planned use of the joint-sealing
element.
[0065] In general, the dimension of the joint-sealing element is
chosen as a function of the profiles being used and of the material
being used. The dimension must be chosen such that the
joint-sealing element fills the gap between the gypsum board and
the ceiling and bears sealingly both on the ceiling and on the
gypsum board. If a vertical movement of the gypsum boards is to be
permitted, the joint-sealing element must follow the movement of
the gypsum board, to ensure that the contact with the gypsum board
is not torn apart and that no spaces can develop between
joint-sealing element and gypsum board. For this purpose, the
sealing profile of the joint-sealing element preferably consists of
resilient and compressible material and is appropriately
precompressed during mounting of the gypsum board, so that a
downward movement of the gypsum board, whereby the gap between this
and the ceiling becomes larger, can be followed. In this way, the
preadjusted freedom of movement of the gypsum board determines the
dimension of the sealing profile and thus of the joint-sealing
element.
[0066] As an example, it must be pointed out that the height of the
shorter side of the mutually parallel sides of a wedge-shaped
sealing profile will be chosen as a function of the desired use of
the joint-sealing element, in which case the height for a
single-boarded arrangement will be chosen as approximately the
thickness of one gypsum board and the height for a double-boarded
arrangement will be chosen as approximately twice the thickness of
one gypsum board. In the case of a single-boarded arrangement,
however, it is also possible to use the joint-sealing element
designed for a double-boarded arrangement.
[0067] As an example, it must also be pointed out that material and
geometry of the sealing profile may be chosen in such a way that
its hardness or compressibility is adjusted such that the sealing
profile is compressed to a well-defined height merely by the dead
weight of the gypsum board in the floor region, for example by
constructing the sealing profile as two layers of foam materials
with different compression density. In this way a correct spacing
between floor and gypsum board can be adjusted without further
measurement. This is necessary in particular whenever damage to the
gypsum board by rising dampness must be prevented.
[0068] The invention will be described in more detail hereinafter
on the basis of application of the joint-sealing element on a
drywall of an arrangement comprising drywall studwork and seal,
without restricting the scope of protection hereby.
[0069] To establish an inventive sealing arrangement for sealing a
joint between two juxtaposed building parts of a building
construction and/or of a building structure with at least one first
building part, one second building part and the inventive
joint-sealing element, the sealing profile is positioned in the
lower region of the joint, preferably on the second building part,
and is configured to seal the joint from outside.
[0070] Preferably the carrier element is disposed on an end edge of
the inside of the first building part. In particular, the carrier
element is to be fastened flush on the upper, inwardly facing,
horizontal end edge of a gypsum board.
[0071] According to the present invention, the first building part
is preferably a drywall and the second building part is a wall, a
ceiling or a floor, preferably a ceiling, of a building
construction and/or of a building structure.
[0072] According to the present invention, the inventive
joint-sealing element, after being attached to a first building
part, is disposed and mounted abuttingly with this on the second
building part. In this arrangement, the joint-sealing element is
positioned in the lower region of the joint and is configured to
seal the joint from the outside.
[0073] In one possibility for sealing a connecting joint in dry
construction, after a profile, especially a channel profile, has
been attached to the connecting building parts, such as a ceiling,
wall or floor, the inventive joint-sealing element is positioned,
fastened and mounted together with the gypsum board on or in front
of that channel profile and on the connecting building part,
preferably a ceiling. In a further working step, a further gypsum
board may be pressed onto the sealing profile, for example at the
front face, so that, in the case of a double-boarded arrangement,
the two gypsum boards are in contact with the sealing profile via
their respective top edge and thereby sealing of the joint is
achieved. In order to permit movement of the gypsum board(s)
without causing a gap to develop between the sealing profile and
the gypsum board or gypsum boards in the case of maximum movement,
the sealing profile must be compressed during mounting of the
gypsum board(s). As soon as the gypsum board has been mounted, the
joint-sealing element is held in place by the precompression.
Furthermore, any irregularities that were present are closed by
this compression.
[0074] For this purpose, the material and the thickness of the
sealing profile are respectively chosen such that the sealing
profile does not hinder the movement of the gypsum board(s) and at
maximum joint width the top edge of the gypsum board(s) still
remains in contact with the sealing profile, in order to ensure
adequate sealing against gases. The width of the sealing profile is
preferably chosen such that it corresponds approximately to twice
the width of one gypsum board. It has been found that sufficient
sealing may also be achieved when the width of the sealing profile
corresponds to the width of only one gypsum board.
[0075] When the joint-sealing element is disposed together with the
gypsum board and then abutted with the ceiling and the channel
profile, irregularities in all building parts can be evened out.
Furthermore, the joint spacing can be controlled by the subsequent
positioning of the gypsum board as well as by the choice of sealing
materials and/or geometric configuration of the joint-sealing
element.
[0076] In a further particularly preferred embodiment, sealing of
the joint can be achieved when, in the case of a double-boarded
arrangement, the two gypsum boards are mounted with a horizontal
offset in such a way that the outer of the two gypsum boards (also
referred to as the outer, second gypsum board) is mounted higher
(i.e. closer to the ceiling) than the inner gypsum board (also
referred to as the inner, first gypsum board). In this embodiment,
the thickness of the sealing profile is chosen to correspond to the
thickness of one gypsum board. The first, inner gypsum board is
mounted together with the sealing profile in such a way that zero
or little precompression of the sealing profile is necessary. The
second, outer gypsum board is attached at a horizontal offset, i.e.
it is mounted higher than the first, inner gypsum board, so that it
partly overlaps the sealing profile. In this case the sealing
profile and the gypsum board should bear sealingly on one another,
in order to seal the gap between the outer, second gypsum board and
the sealing profile, especially against gases. Thus sealing is
achieved between sealing profile and the second building part, such
as a ceiling, a wall or a floor, as well as between sealing profile
and outer, second gypsum board.
[0077] An empty gap remains between the second building part, such
as a ceiling, a wall or a floor, and the outer, second gypsum
board. In the case of a vertical movement of the second building
part or of the gypsum boards, this gap is completely available to
absorb movement.
[0078] Depending on how far the outer, second gypsum board overlaps
the sealing profile (size of the offset), a movement in the other
direction may also be absorbed. In this case, it is important that
an overlap is still ensured between the second gypsum board and the
sealing profile. Preferably, therefore, the dimension of the
sealing profile is chosen such that its thickness is somewhat
larger than the thickness of one gypsum board and its height
comprises somewhat more than the maximum permissible movement of
the building parts (maximum joint width).
[0079] By the fact that the thickness of the sealing profile is
larger than the thickness of the gypsum board, the gypsum board is
pushed against the sealing profile and somewhat compressed while it
is being mounted, whereby the gap between sealing profile and
gypsum board is reliably sealed, especially against gases.
[0080] In this type of mounting, maximum absorption of movement
relative to the joint width is possible. Furthermore, this type is
very mounting-friendly, since firstly the first gypsum board can be
mounted together with the sealing profile without the need to
measure the spacing. Secondly, the second gypsum board can also be
mounted without measurement of the spacing. Furthermore, this type
of mounting permits the greatest possible freedom in the choice of
material for the sealing profile, since this is compressed only
slightly and thus only slight requirements are imposed on the
compressibility of the sealing profile.
[0081] According to the invention, the joint-sealing element can be
on all kinds of connecting joints in which one building part meets
another building part. Accordingly, the joint-sealing element can
be applied on all profiles, even closed profiles or wooden beams,
which must be sealed at a connecting face.
[0082] A particularly preferred application of the joint-sealing
element relates to sealing the profiles in dry construction,
wherein the first building part is a drywall, for example one or
more gypsum boards, which bear tightly against the profiles and are
fastened to the studwork, and the second building part is a wall, a
ceiling or a floor of a building element, for example a masonry
structure or concrete building element. A further building part is
a profile for positioning and fastening of the gypsum board,
wherein it may be any of the profiles commonly used for dry
construction, regardless of whether is has a slotted or non-slotted
web or slotted or non-slotted flanges. In order to permit vertical
movement of the gypsum boards, for example in the event of an
earthquake, the gypsum boards are mounted to be vertically movable
at a spacing from a wall, a floor or a ceiling. Thereby a space
(also referred to as joint herein) is formed between the gypsum
board and the wall, the floor or the ceiling. This joint is filled
by the sealing profile of the joint-sealing element, so that the
sealing profile seals the joint against sound and/or smoke and,
depending on material of the sealing profile, also against fire if
necessary.
[0083] Without restricting the scope of protection of the
invention, the invention will be described in more detail on the
basis of special embodiments of the joint-sealing element as well
as its positioning. In these embodiments, the joint-sealing element
is applied to the connecting joints in drywalls. It is clear to the
person skilled in the art that the joint-sealing element may also
be applied to building-structure joints of other types. It is also
clear to him or her that, by virtue of the different geometries of
the sealing profile, it is possible for intermediate spaces known
as cavities to be formed between sealing profile and carrier
element.
[0084] A preferred embodiment of an inventive joint-sealing element
1 is shown in FIGS. 1a and 1b. Joint-sealing element 1 has a
sealing profile 3, which is positioned on the outer periphery of
carrier element 2. Sealing profile 3 has a round profile and a
solid profile, wherein carrier element 2 is positioned laterally on
round sealing element 3. Furthermore, sealing profile 3 is
surrounded completely, i.e. over its entire circumference, by
carrier element 2. Sealing profile 3 consists of a compressible
foam, which if necessary contains fire-protection additives, and
carrier element 2 consists of a plastic film. Carrier element 2 has
a fastening region 4 oriented in the direction of the longitudinal
extent of the joint for fastening of the joint-sealing element to a
construction element of the building construction and/or of the
building structure disposed peripherally on the joint. Fastening
region 4 of the joint-sealing element is provided with an adhesive
layer.
[0085] A further preferred embodiment of an inventive joint-sealing
element 1 is shown in FIGS. 2a and 2b. Joint-sealing element 1 has
a sealing profile 3, which is positioned on the outer periphery of
carrier element 2. Sealing profile 3 has a solid profile and a
wedge profile, wherein carrier element 2 is positioned on the short
side of the mutually parallel sides of wedge-shaped sealing profile
3. The shorter side of the mutually parallel sides of wedge-shaped
sealing profile 3 is provided for bearing on the profile and the
inclined side of the wedge is provided for bearing on the second
building part. Furthermore, sealing profile 3 is partly surrounded
by carrier element 2. Sealing profile 3 consists of a compressible
foam, which if necessary contains fire-protection additives, and
carrier element 2 consists of a plastic film.
[0086] Positionings of joint-sealing elements according to various
embodiments of the present invention on a first building part are
shown in FIGS. 3a and 3b.
[0087] Any geometric as well as material configuration of the
sealing profile and of the carrier element mentioned in the
foregoing can be combined and used in any way in order to provide a
joint-sealing element according to the present invention.
[0088] FIGS. 4a to 4c show the stepwise procedure for sealing a
joint between two juxtaposed building parts of a building element
by means of the embodiment of an inventive joint-sealing element
shown in FIGS. 1a and 1b. To seal the gap between a ceiling 6,
channel profile 9 of a drywall studwork and gypsum boards 5,
joint-sealing element 1, in the first step, is positioned on end
edge 7 of first building part 5 and fastened by adhesive and, in a
second step, is positioned together with this building part 5 on
second building part 6 and fastened in the usual way, e.g. by
screws or nails. Thereby sealing profile 3 is compressed and in
this way seals the gap between ceiling 6 and channel profile 9 as
well as the gap between ceiling 6 and gypsum board 5. Then, in a
last step, a further gypsum board 5 can be laid against the first
gypsum board and pushed slightly upward in the direction of ceiling
6. Thereby sealing profile 3 is compressed once again and in this
way seals the gap between ceiling 6 and channel profile 9 as well
as the gap between ceiling 6 and gypsum board 5.
[0089] FIGS. 5a to 5c show the stepwise procedure for sealing a
joint between two juxtaposed building parts of a building element
by means of the embodiment of an inventive joint-sealing element
shown in FIGS. 2a and 2b. To seal the gap between a ceiling 6,
channel profile 9 of a drywall studwork and gypsum boards 5,
joint-sealing element 1, in the first step, is positioned on end
edge 7 of first building part 5 and fastened by adhesive and, in a
second step, is positioned together with this building part 5 on
second building part 6 and fastened in the usual way, e.g. by
screws or nails. In the case of use of a wedge-shaped sealing
profile, sufficient sealing is achieved by simply tilting the
gypsum board against the profile and the ceiling, so that the joint
gap corresponds to the height of the shorter side of the mutually
parallel sides of wedge-shaped sealing profile 3. Thereby sealing
profile 3 is compressed and in this way seals the gap between
ceiling 6 and channel profile 9 as well as the gap between ceiling
6 and gypsum board 5. Installation is greatly facilitated by a
wedge-shaped sealing profile, since the shape permits sliding or
slipping into the correct position. Then, in a last step, a further
gypsum board 5 can be laid against the first gypsum board and
pushed slightly upward in the direction of ceiling 6. Thereby
sealing profile 3 is compressed once again and in this way seals
the gap between ceiling 6 and channel profile 9 as well as the gap
between ceiling 6 and gypsum board 5.
[0090] A sectional view through a finished building element with
the embodiment of an inventive sealing arrangement shown in FIGS.
1a and 1b is sketched in FIG. 6. In particular, FIG. 6 shows the
positioning of an embodiment of the inventive joint-sealing element
1 in a connecting joint of drywalls with a double-boarded
arrangement.
[0091] A sectional view through a finished building element with
the embodiment of an inventive sealing arrangement shown in FIGS.
2a and 2b is sketched in FIG. 7. In particular, FIG. 7 shows the
positioning of an embodiment of the inventive joint-sealing element
1 in a connecting joint of drywalls with a double-boarded
arrangement.
[0092] As is obvious from the foregoing explanations, the inventive
joint-sealing element is particularly suitable for safely sealing a
building-structure joint between two adjacent building parts in
simple manner, especially against sound and/or smoke and if
necessary also against fire.
[0093] The joint sealing element of the present invention can be
readily compressed and deformed and thereby improved evening-out of
irregularities can be achieved, as can improved installation, e.g.
simple laying around a corner, as well as improved sealing, e.g.
when several joint-sealing elements are made to abut against one
another.
[0094] The method for sealing a joint permits simple execution and,
with little working effort, leads reliably and without defects to
sealing of a joint between two juxtaposed building parts of a
building construction and/or of a building structure.
[0095] It has been shown that, in the event of fire, the sealing
arrangement permits better sealing of the joint between two
building parts, especially between a drywall and a connecting
building part, such as a wall, a ceiling or a floor, and in this
way better and durable sealing against sound and/or smoke and if
necessary better and durable fire protection can be provided, and
it can be mounted reliably and free of defects with little working
effort.
[0096] Application is very mounting-friendly, since no additional
fastening of the joint-sealing element, for example to the profile
or to the ceiling, is necessary. Accurately fitting placement of
the joint-sealing element, for example against a profile or a
ceiling, is also unnecessary, by virtue of the fixation and
fastening of the joint-sealing element during mounting of the
gypsum board on a profile. Mounting is therefore remarkably easy,
and the working effort for mounting the joint-sealing element is
greatly reduced. By means of the invention, therefore, safe and
reliable sealing of joints between two building parts is achieved,
especially between a gypsum board of a drywall studwork and a
building part adjacent to it, such as a ceiling, wall or floor.
[0097] Furthermore, it has been shown that outstanding
imperviousness can be achieved with the inventive joint-sealing
element, since good compressibility of the sealing profiles is
ensured without additional auxiliary means by the choice of the
sealing materials and/or geometric configuration. By appropriate
choice of the sealing materials and/or geometric configuration, the
invention also makes it possible to adjust the correct spacing of
gypsum board from the connecting building part without additional
auxiliary means, in order to achieve the said precompression.
[0098] By means of the inventive joint-sealing element it is also
possible to ensure that, merely by the choice of the sealing
material and/or geometric configuration, sufficient material is
installed to ensure excellent imperviousness with maximum
absorption of movement.
[0099] By means of the inventive joint-sealing element it is
further possible to seal irregularities of the surface of a
building part safely merely by disposing one building part against
another building part, since the sealing profiles of the
joint-sealing element are pressed sufficiently firmly against the
surface of the one building part and simultaneously against the
side faces of the other building part.
[0100] In view of the foregoing, it is obvious that the objects of
the invention have been accomplished. Since various modifications
can be made to the joint-sealing element described hereinabove,
without departing from the scope of the invention, it is intended
that all subject matters contained in the foregoing description be
interpreted as illustrative and not in a restrictive sense.
