Description
BACKGROUND
[0001] 1. Technical Field
[0002] The present invention relates to a box element for use in
joining two building elements, a flange for use together with the
box element, a system for use in joining two building elements and
a method for the same.
[0003] 2. Related Art
[0004] When building elements are to be assembled into a building,
there are many ways this can be done. One such way is a system that
is invisible after assembly. A non-visible system can also be
configured in several ways: there may be systems including movable
bridge elements that are moved from an approximately retracted
position in which they do not project beyond the building element
to a forward position in which they can be in engagement with both
building elements that are to be joined. Another alternative is a
system in which there is a projecting bridge element that cannot be
moved relative to the building element and where the second
building element is suspended from this bridge element. In the
first case, too, the second building element can be suspended from
the bridge element, but with the movable bridge element, the second
building element can be moved into a joining position, the bridge
element then being moved into a forward position where by means of
this movement it is moved into engagement with both building
elements. This first system with a movable bridge element thus has
advantages over the system with the non-movable bridge element,
such as no projecting parts during transport but where all parts
are in place during transport, and greater possibilities as regards
joining building elements.
[0005] Such systems may also be suitable for use, for example, in
attaching balconies and external galleries to an outside of a
building. These invisible joining systems entail that elements must
be fastened to bearing structures, and these elements must then
inevitably extend through insulation and an outer cladding. It has
been found difficult to obtain a good seal around these through
passages in a simple manner.
SUMMARY
[0006] One or more embodiments of the present invention provides a
simple way of producing a good seal around elements that are used
in connection with the joining of two building elements, such as a
wall and a balcony or an external gallery, where an element, for
example, is to extend through a layer of insulation.
[0007] One or more embodiments of the present invention relates to
a box element for use in joining two building elements. These
building elements may be a wall and a balcony or an external
gallery. The box element comprises a main body having a
longitudinal axis and a first end which, in a mounted state, when
the box element is secured in relation to a first building element,
is arranged facing out from the first building element. The main
body also comprises means such that the box element can be used for
joining two building elements. These means may either be an inner
cavity adapted for insertion of a bridge element, which either is a
movable bridge element or a fixed bridge element, or they may
consist in the main body comprising an extended projecting end
capable of engaging with the second building element. The box
element further comprises a first flange which extends in a
direction substantially radial to its longitudinal axis and is
connected to an outer side of the main body. The first flange also
extends around the whole main body.
[0008] According to one or more embodiments of the invention, the
first flange is arranged at a distance from the first end and the
flange is adapted to abut against a portion of the first building
element. The relative distance between the first flange and the end
is such that the end, in a mounted state, will be located at a
distance from the first building element. The main body further
comprises at least one fastening device, the main body and
fastening device being so configured that a second flange can be
introduced over the end and secured to the main body, such that a
sheet membrane of the first building element, during mounting of
the box element, can be sandwiched between the first and second
flange, thereby forming a substantially leak-proof connection. The
leak-proof connection is formed between the box element and the
sheet membrane and will thus prevent, for example, rain water from
seeping in around the box element and into the building element,
and, for example, an insulation layer arranged inside of the sheet
membrane.
[0009] According to one aspect of the invention, at least one
fastening device may be secured to an outer side of the main body
between the end and the first flange. In one variant it is
conceivable that the fastening device is secured to an inner side
of a cavity in the main body.
[0010] In one embodiment, the fastening device may comprise a
bracket element secured to the main body and an attachment element
movably arranged in relation to the bracket element. The bracket
element may be secured to the main body, for example, by welding,
screw fastening or be formed as a piece of the main body that is
turned out relative to the rest of the main body so as to form a
bracket. The attachment element may, for example, be an element
which at least in a part of its surface has external threads and
which is moved relative to the bracket by, for example, being in
engagement with internal threads in a through hole in the bracket.
This attachment element, at one end facing the flange, may be
configured with a termination which has a larger area than a
cross-sectional area of the portion with the external threads.
[0011] According to one aspect, the main body may have a
substantially quadrangular cross-section. Here, it is conceivable
that the cross-section is rectangular or square. It is also
possible to form the main body with cross-sections other than
quadrangular, for example, pentagonal, triangular, partly curved
etc. When the cross-section is quadrangular, fastening devices can
in one embodiment be secured to two opposing sides of the
cross-section.
[0012] According to another aspect, the first flange may be
connected in a leak-proof manner to the main body around a
periphery of the main body. Such a leak-proof connection can be
obtained by, for example, welding or alternatively by means of a
sealing system in the form of sealing elements between the flange
and the main body.
[0013] According to one or more embodiments of the invention, a
flange is provided for use in connection with a box element as
defined above. According to one or more embodiments of the
invention, the flange comprises a through opening that is larger
than an external cross-section or periphery of the main body, and
where the opening is so configured that the flange can be
introduced over the main element and the fastening devices and,
once in position for securing, laterally displaced in relation to
the longitudinal axis of the main body so as to enable the
fastening devices to engage with the flange. When the main body has
a rectangular cross-section, an opening in the flange will have a
rectangular shape, wherein one width is just slightly larger than
an outer form of the main body, and it will essentially be such
that it is possible to displace the flange in relation to the main
body, whilst the second width is somewhat larger so that it is also
possible to obtain a lateral displacement when the flange has been
put in place.
[0014] One or more embodiments of the present invention also
comprises a system for use when securing one building element to
another building element. The system comprises a box element and a
flange as defined above, wherein the box element comprises an inner
cavity and the end that will project from the building is an open
end. The system further comprises a bridge element movably arranged
in the cavity of the box element, which bridge element can be moved
from a retracted position approximately inside the box element to
an extended position in which a part is inside the box element and
a part of the bridge element extends out of the box element and,
when building elements are joined, will be in engagement with the
second building element.
[0015] One or more embodiments of the present invention further
relates to a method for establishing a leak-proof attachment of a
box element of a joining system for joining one building element to
another building element, to one of the building elements, where a
box element as defined above is secured to one of the building
elements, a sheet membrane covering at least a part of the building
element and having a hole for a portion of the box element is
placed in abutment against the first flange, between the flange and
the end of the box element, a second flange, as defined above, is
introduced over the end and secured by fastening devices to the box
element such that the sheet membrane is sandwiched between the
first and second flange and a leak-proof connection is formed.
Leak-proof in this context should be understood as leak-proof
against a liquid such as water.
[0016] Furthermore, either a bridge element which is inside the box
element is pulled out or a bridge element can be inserted into the
box element, and a second building element can be secured to the
first building element.

[0022] FIG. 5 is a basic diagram showing how the device in FIG. 1
can be secured to a building element.
DETAILED DESCRIPTION
[0023] Hereafter, embodiments of the invention will be described.
In embodiments of the invention, numerous specific details are set
forth in order to provide a more thorough understanding of the
invention. However, it will be apparent to one of ordinary skill in
the art that the invention may be practiced without these specific
details. In other instances, well-known features have not been
described in detail to avoid obscuring the invention.
[0024] FIGS. 1 to 4 show the same system seen from different sides.
The box element 1 comprises a main body 10, in this embodiment
formed having four side panels 11, 12, 13, 14 which define a
rectangular outer cross-section. The four side panels 11, 12, 13,
14, are at one end joined to an end panel 15 and thus define an
inner cavity which at the opposite end 16 to the end panel 15 is
open. A longitudinal axis for the main body extends from the end
panel 15 to the opposite end 16. Affixed to the side panels are
fastening devices 19 for securing to a first building element (not
shown). Alternatively, this box element may also be cast in the
building element. A first flange 17 is fastened to the main body 10
at a small distance from the open end 16, and extends in a
substantially radial direction in relation to the longitudinal axis
of the main body. Furthermore, between the open end 16 and the
first flange 17, two fastening devices 18 are affixed to an outer
side of two opposing side panels 11, 13. When the box element is
unmounted and not screwed together, there is a small distance
between the fastening devices 18 and the first flange 17.
Furthermore, a second flange 20 can be seen which has been
introduced partly over a bridge element 30 arranged inside the
inner cavity of the box element 1, where the bridge element 30 in
the figure is in an extended position. The second flange 20 is
configured with a through opening 21 which is adapted to the outer
periphery of the main body and which also comprises cut-outs 22
having a shape corresponding to the fastening devices 18, such that
the second flange 20 can be introduced over the end 16 and the
fastening devices 18, and when the second flange 20 has been moved
to a position between the fastening devices 18 and the first flange
17, it can be laterally displaced thereby allowing the fastening
devices 18 to obtain engagement with the second flange 20 and press
the second flange 20 against the first flange 17 when the fastening
devices 18 are tightened. It can be seen in FIG. 1 and FIG. 4 that
the opening 21 has a form such that the second flange can be
laterally displaced. Furthermore, it can be seen from FIG. 3 and
FIG. 4 that sound damping elements 40 are disposed between the
bridge element 30 and the main body 10, such that sound transfer
between the two building elements can be dampened. The sound
damping elements 40 may be in the form of a rubber sleeve, or two
U-shaped rubber elements, with grooves in their surface such that
cavities are formed between the rubber sleeve and the main body 10.
It can also be seen from FIG. 3 that the bridge element comprises a
hole 31 for attachment of a stop member 31 (shown in FIG. 5) which
prevents the bridge element from moving into the box element again
during mounting.
[0025] FIG. 5 shows the box element mounted in connection with a
building element. The main body 10 is secured by fastening devices
19 to the building element 50, for example, a hollow core slab. The
box element 1 is secured to the hollow core slab 50 such that it
extends through a first layer 51 of the building element that runs
essentially at right angles to the hollow core slab 50. This first
layer 51 may, for example, comprise a layer of insulation. The
first flange 17 rests against this first layer 51 with the side of
the first flange 17 that faces away from the open end 16.
Alternatively, there may be a distance between the first flange 17
and this first layer 51. When the box element 1 is mounted to the
hollow core slab 50 such that it extends through the layer 51, a
sheet membrane 52 with openings for the end 16 of the main body 10
is mounted such that the sheet membrane 52 rests against the side
of the first flange 17 facing towards the end 16. The opening in
the sheet membrane 52 is such that it easily passes over the end
16, but the sheet membrane 52 and the flange 17 are formed so as to
produce an overlap of the sheet membrane 52 in relation to the
first flange 17. The second flange 20 is introduced over the end 16
and secured to the main body 10 and with this pressed against the
first flange 17, so that the sheet membrane 52 is sandwiched
between the first and the second flange 17, 20 and a sealed
connection is obtained, such that, for example, water cannot seep
into the first layer 51 of the building element. According to one
or more embodiments of the present invention, the size of the
flanges 17, 20 is the same and must also be such that there is a
good overlap between flanges and sheet membrane. The bridge element
30 can now, if not earlier, be moved into an extended position,
drawn forward and secured in this position, thereby allowing a
second building element to be secured to the projecting end of the
bridge element. Alternatively, the second building element can be
moved so that it has a receiving part for the bridge element
aligned with the end, where the bridge element is then moved from a
retracted position to an extended position in which it engages with
the receiving portion of a second building element (not shown).
[0026] The invention has now been explained by non-limiting
exemplary embodiments. One of skill in the art will understand that
changes and modifications can be made to the illustrated examples
which are within the scope of the invention as defined in the
claims below.
[0027] While the invention has been described with respect to a
limited number of embodiments, those skilled in the art, having
benefit of this disclosure, will appreciate that other embodiments
can be devised which do not depart from the scope of the invention
as disclosed herein. Accordingly, the scope of the invention should
be limited only by the attached claims.
