Description
PRIORITY DATA
[0001] This application is a continuation of International Pat.
Appln. No. PCT/EP01/14833, filed on Dec. 15, 2001, which claims
priority from German Pat. Appln. No. 200 21 878.6, filed on Dec.
29, 2000.
BACKGROUND OF THE INVENTION
[0002] The invention relates to a facade and/or a roof that
includes a sealing strip with a filling piece.
[0003] In the design of facades and light roofs,
condensation-collecting gutters are principally located on the beam
sections which, separated from the seepage water drain, carry away
the condensation in separate gutters or cavities of the post
sections or sealing systems. The principal reason for this is that
the inner pane level or filler level forms the critical sealing
level so as to prevent the passage of interior air into the pane
rabbet of the facade as far as possible. Combining the condensation
gutter with the seepage water drain would automatically let warn
interior air into the groove which, in the case of insulating glass
panes, would increase the danger of water vapor diffusing into the
space between the panes.
[0004] The aforementioned designs are not cost-effective to
construct. Accordingly, it is the object of the invention to
develop a cost-effective drain for water condensation. In
particular, an object if the invention is to preclude any exchange
of air between the interior and the glass rabbet of the facade or
of the light roof in a cost effective manner.
BACKGROUND OF THE INVENTION
[0005] Broadly, the condensation gutter of the beam section is
guided directly into the seepage water groove of the post section
and sealed in this area by a filling piece. The filling piece is
preferably designed to prevent any exchange of air while allowing
condensation to pass through.
[0006] Use of these filling pieces is advantageous in those facade
and light roof designs in which the condensation gutters are
located in the seals for mounting the glass, and in designs in
which the condensation gutters are attached in one piece to the
facade sections themselves, or by using accessory sections.
[0007] The filling piece is comprised preferably of fibers,
specifically in a design in which the fibers are arranged layered
longitudinally in the direction of flow, or chaotically intertwined
or felted. The fibers are made preferably of fiberglass or plastic,
especially polyamide.
[0008] Use of a suitably fine filter structure in the filling
pieces prevents any exchange of air between the interior and the
drainage level. The diffusion of vapor through joints in a sealing
system is not increased or negatively affected by these filling
pieces. When the capillaries and spaces between fibers are filled
with liquid, any vapor diffusion in this area is minimized or
reduced to zero.
[0009] In one embodiment, at least one sealing strip of the beam
sections and/or post sections has at least one drainage gutter,
preferably, a condensation gutter. The condensation gutter is
preferably molded onto the sealing strip in one piece.
[0010] The condensation gutter of the sealing strip is of a
visually attractive and functional design, preferably rectangular,
and preferably dimensioned according to the subjects of the
additional subclaims such that it is in an especially advantageous
relationship relative to the other sealing strips of the post
sections.
[0011] The seals are made of an elastic material, may be easily
modified using simple tools such knives and shears, and ensure a
high level of sealing without special demands being placed on the
worker.
[0012] The condensation gutter on the sealing strip of the stay bar
visually balances the height differences of the seals relative to
the post.
[0013] These and other objects, features and advantages of the
present invention will become more apparent in light of the
following detailed description of the preferred embodiments
thereof, as illustrated in the accompanying drawings.

DETAILED DESCRIPTION OF THE DRAWINGS
[0031] FIG. 1 shows part of a facade of a metal-glass design with a
metal framework comprising post sections 1, and beam sections 2
that are at an angle relative to the post section, the beam
sections being mounted on post section 1.
[0032] The faces of post section 1 and beam section 2 each have a
center rib 100 for the attachment of caps 101. These caps hold
in-filling items such as panes, for example insulating panes
102.
[0033] Beam section 2 is clinched at the ends such that the section
wall 3, which faces the insulating glass pane and forms the base
for the seepage water groove 4 and sealing groove 5, rests when
assembled on the sealing groove 6 of post section 1.
[0034] Viewed from the building side of the facade outward, sealing
groove 6 of post section 1 is located above cavity 7. A sealing
groove 6 and a cavity 7 together delimit a seepage water groove 8
of post section 1.
[0035] In a variant shown as an example in FIG. 1 on the right side
of post section 1, sealing groove 6 on post section 1 may also be
open at the bottom such that sealing groove 6 extends into the
region of cavity 7, and sealing groove 6 is effectively integrated
with cavity 7 to form a sealing groove 9 which combines the
functions of the sealing groove and cavity.
[0036] Together with the actual glass mounting region 10a and the
seal base 10b of beam section 2, the sealing strip 10
advantageously has a condensation gutter 11 molded on as a single
piece to glass mounting region 10a, the gutter being preferably
rectangular.
[0037] Condensation gutter 11 together with the groove wall facing
the sealing body of sealing strip 10 adjoins the outer surface of
beam section 2 forming a seal. The groove base 12 adjoins the
bottom of section wall 3, and is flush and aligned with it. In
principle, condensation gutter 11 may also have any other shape,
such as that of a round cross-section, although the rectangular
shape is preferred based on its visual appearance and stability.
The essential requirement is that the gutter cross-section be
dimensioned so as to create a sufficiently large water drain and
sufficient stability. Another especially advantageous feature is
the one-piece design of sealing strip 10. However, multi-piece
variants of the sealing strip are theoretically also
conceivable.
[0038] Sealing strip 10 is guided into the region of sealing strip
13 of post section 1 where it rests against a sealing corner piece
14, to which the glass mounting seal 13 of post section 1 is
attached or joined.
[0039] Sealing corner piece 14 has an extension 15 matching
condensation gutter 11 and interfacing with sealing strip 10 of
post section 2, which extension encloses condensation gutter 11
laterally and from the bottom, thereby supporting and aligning
it.
[0040] Sealing corner piece 14 includes a condensation gutter
facing the beam section, which gutter discharges in the alignment
region of sealing strip 13 into a closed hollow channel from which
an outlet 16 is guided downward, passing through groove base 17 of
sealing groove 6 and discharging into cavity 7. Alternatively,
outlet 16 discharges into sealing groove 9, which is open at the
bottom. In this case, outlet 16 may be eliminated so that only one
outlet hole is present in the sealing body of sealing corner piece
14.
[0041] The facade designs with the new seal shown in FIG. 1 provide
a cost-effective condensation drainage system of simple
construction which functions reliably and separately from the
seepage water drainage of seepage water gutters 4 and 8.
[0042] FIG. 2 shows a facade design in which the post section and
beam section 1, 2 are unchanged from FIG. 1. Augmenting the design
of FIG. 1, however, sealing strip 21 of post section 1 here also
has a condensation gutter 18 molded directly onto the glass
mounting region of the sealing strip, which gutter again is
surrounded and supported by an extension 19 of a sealing corner
piece 20.
[0043] Sealing corner piece 20 includes a type of base which
engages both sealing groove 5 of the beam section and sealing
grooves 6, 9 of the post section and is fixed there by a
form-fitting shape.
[0044] In addition, sealing corner piece 20 has a channel aligned
with condensation gutter 11 and extending this gutter, which
channel passes through the leg of the sealing corner piece which is
aligned with sealing strip 21.
[0045] As a result, seepage water gutter 8 of the post section is
directly connected to the condensation drainage system thereby
directly draining the condensation directly into the seepage water
drainage system.
[0046] Sealing corner piece 20 may have a drain extension for
seepage water groove 8.
[0047] In FIG. 2, the drainage systems for condensation and seepage
water are no longer separated but combined into a single integrated
system.
[0048] This approach reduces the exchange of air between seepage
water groove 8 and condensation gutters 11, 18. For this purpose, a
fibrous filter insert (filling piece) 25 is inserted into the
channel that connects the condensation gutters to seepage water
gutter 8 of the post section, which filter insert blocks the
exchange of air while at the same time diverting the collecting
condensation into the seepage water drain through adhesion and
capillary action.
[0049] Both of the two different drainage systems of FIGS. 1 and 2,
that is, the combined and separate drains and the placement of a
condensation gutter 18 on sealing strip 21, may be used or
interchanged in any way desired.
[0050] For inclined surfaces, sealing strip 10 along with its
attached integrated gutter 11 for beam section 2 can be located on
the top side of the beam section. In the case of lesser
inclinations of the roof surfaces or facade surfaces, this seal may
also be located along both sides of the beam section. The same
applies also to facades in which condensation generated by the
condensation gutter which appears at the top side of the beam
sections may be covered and carried away.
[0051] FIG. 3 is a top view of an intersecting point of post
section 1 and beam section 2. Sealing strip 21 with its integrated
condensation gutter 18 is located on post 1. Sealing strips 10, 21
are connected by sealing corner piece 20. Condensation gutters 11,
18 are enclosed and supported by extensions 15, 19, with an
appropriate seal being provided. In addition, appropriate enlarged
bonding surfaces are provided for attaching the seals to the
sealing corner piece.
[0052] FIG. 3 shows the separate drain for seepage water into space
9 or cavity 7 under sealing strip 21. The drainage channel 23,
which is an extension to condensation gutter 11 leads into sealing
corner piece 20 to outlet 16.
[0053] In contrast to FIG. 3, FIG. 4 shows a sealing strip, here a
glass mounting seal 13 for post 1 without condensation gutter.
[0054] FIG. 5 is a top view of a facade of the type shown in FIG.
2. Drainage channel 24 in particular is readily visible in this top
view of a section intersecting point, the channel being aligned
with condensation gutter 11 and discharging into seepage water
groove 8 of post section 1. This drainage channel is filled by the
filter insert (filling piece) 25 which blocks the exchange of air
between seepage water grooves 8, also called the rabbet cavity, and
the condensation gutters, also called the interior. Only the
condensation is carried away through the channels formed by the
fibers by adhesion to the fibers or by capillary action.
[0055] FIG. 6 essentially matches the design of FIG. 1, the only
difference being that sealing strip 13 is designed without a
condensation gutter, and the drainage is effected--as in FIG.
5--via drainage channel 24 and the installed filter insert (filling
piece ) 25.
[0056] In FIG. 7, only sealing strip 13 is inserted in post 1.
Sealing strip 10 along with condensation gutter 11 adjoins a
sealing end piece 26 which extends beam seal 10 into the region of
post section 1. Sealing end piece 26 engages sealing groove 5 of
the beam section by a base feature and is fixed therein by seal 10.
The width of sealing end piece 26 matches the overall width of
sealing strip 10 including condensation gutter 11 so that, under
pretension, the front face of seal 13 may form a tight fit with the
outer face of sealing end piece 26. As an extension of condensation
groove 11, the sealing end piece 26 includes a drainage channel 27
which may have a condensation gutter 11 located upstream from it.
Drainage channel 27 discharges into outlet 16 which in turn
conducts the condensation into space 9 or cavity 7 of the post
section separately from the seepage water.
[0057] As in FIG. 7, FIG. 8 shows an intersecting point for post
section 1 with beam section 2. Shown here is sealing end piece 28
which is provided in the overlap region between the beam section
and the post, with drainage channel 27 of this end piece
discharging into drainage channel 8 or into the rabbet of the post
section. This sealing end piece 26 is especially well suited for
inclined abutting beam sections, since sealing end piece 26 may be
correspondingly sized to the abutment angle of the sections.
[0058] Sealing end piece 26 has a smooth surface facing sealing
strip 13, against which surface glass mounting seal 13 may be
mounted to form a tight seal. As has already been shown in FIGS. 5
and 6, discharge channel 27 is equipped with filter insert (filling
piece) 25.
[0059] FIGS. 9 and 10 reveal an additional aspect of this
interconnection by which sealing end piece 26 primarily supports
the intersecting points at which beam section 2 adjoins the post
section at an angle. For this purpose, sealing end piece 26 is
longer than is required for the right-angle abutment so as to be as
easily adaptable as possible to changed conditions.
[0060] FIG. 9 shows the already mentioned oblique abutment of the
beam section against the post section, and thus matches FIG. 7
already described. Only sealing end piece 26 and sealing strip 13
have been adapted to the abutment angle of the sections.
[0061] FIG. 10 is a top view of an oblique abutment of the beam and
the post, otherwise matching the description of FIG. 8. Only
sealing end piece 28 and sealing strip 13 of the post section have
been appropriately adapted to the intersection angles.
[0062] FIG. 11 is a perspective exploded view showing the design of
a beam post interface of a facade. Beam section 2 overlaps stay bar
section 1 in the region of the sealing groove. Level compensation
is achieved by the varying height of the seal 10 and seals 13,
13.1. This height difference is effectively compensated by sealing
corner piece 14. Sealing corner piece 14, and a sealing strip
without a condensation gutter 18 as in FIG. 2, are shown here.
Sealing corner piece 14 is clearly evident here. On its legs in the
abutment region, the sealing corner piece has centering toes 29,
30, 31 which interact with the corresponding cavities of the glass
mounting sections, engaging these so as to secure the relative
positions of the individual components. At the same time, the toes
create an enlargement of the contact surfaces for possible
cementing of the components.
[0063] Either drainage outlet 16, or drainage extension 22 together
with drainage channel 27 sealed by filling piece 25, may be located
on sealing corner piece 14, or alternatively, on sealing corner
piece 20.
[0064] FIG. 12 also provides an exploded perspective view of an
intersecting abutment of a beam/post facade. Sealing end piece 26
is shown in this figure, this piece similarly having a centering
toe 29 which interacts with a cavity of glass mounting section 10.
Glass mounting section 13 rests elastically on the outer surface of
sealing end piece 26.
[0065] To implement separate drainage of condensation, sealing end
piece 26 may be fitted with outlet 16, or in the event condensation
is combined with the seepage water, with drainage channel 27 and
filter insert (filling piece) 25.
[0066] FIG. 13 shows sealing corner piece 14, also analogously
representing sealing corner piece 20, in which the same details
described above may also be found. In place of drainage channel 27
and the already described sealing insert 25, the sealing corner
piece must be fitted with outlet 16 for separate drainage of
condensation.
[0067] The same applies to FIG. 14, which shows sealing end piece
26.
[0068] In place of sealing corner pieces or sealing end pieces,
sealing strip 10 together with condensation gutter 11 may extend
continuously into the overlap region of beam 2 and post 1 (not
shown here). Sealing strip 13 of the post section is then guided
under pretension to the outer surface of condensation groove 11, an
adapter piece being inserted into condensation gutter 11 in the
region of sealing strip 13, which adapter piece both equalizes the
overall height up to the glass support and seals condensation
gutter 11 so as to allow drainage of condensation into space 9
under sealing strip 13, or into cavity 7 via a punched hole in the
groove base of condensation gutter 1 1.
[0069] The adapter piece may also be in the form of a channel in
which filling piece 25 is located which enables drainage into the
rabbet or seepage water groove 8.
[0070] Especially in this latter embodiment, but also in the
embodiments of FIGS. 7, 8, 9, 10, 12, and 14 which all relate to
sealing end piece 26, compensation of levels between the beam
section and the post section relative to the glazing level may also
be implemented by a two-part post seal 13 (see FIG. 18). The
specific concept to be considered here is a combination of an
aluminum base strip and matching sealing strip 10 without the
condensation gutter.
[0071] The following discussion describes in more detail the design
of the sealing strips, specifically the sealing strips with an
attached or molded-on drainage channel.
[0072] FIG. 15 shows an enlarged cross-section of sealing strip 10
which rests at plane X on the two upper edges of sealing groove 5
and is held by form fit inside beam section 2 by the seal base. A
rib 10c adjoins the sealing body-that is, the conventionally
designed glass mounting region 10a with its molded-on seal base 10b
engaging sealing groove 5,--which rib is directly molded on
laterally to glass mounting region 10a, and has substantially the
same height as glass mounting region 10a. Condensation gutter 11,
which is open on the side facing the insulating glass pane but is
otherwise rectangular and substantially "U-shaped," adjoins stable
web 10c which overlaps the outer lateral edge of sealing groove 5,
the condensation gutter being formed by groove walls 12, 200 and
groove base 130, and resting on beam section 12 by its wall or side
12 facing beam section 2. The plane Y of groove wall 12 relative to
the sealing body thus forms the lateral attachment and support
plane on beam section 2.
[0073] The sealing body or glass mounting region 10a has a height
"a" viewed from plane X (i.e., the upper edge of sealing groove 5),
while the seepage water groove has the dimension "b" starting from
plane X up to the lower edge of groove base 130. The effective
overall height "H" of sealing strip 13 for post section 1 is
composed of the height of the glass mounting region plus the
dimension "b" of the seepage water groove, that is, "a+b."
[0074] Dimensions a and b are chosen such that groove base 130 of
the seepage water groove rests on the upper edges of sealing groove
6 of the post sections. Groove wall 200 then rests vertically on
groove base 130, and in this particular embodiment forms part of
the support surface for sealing strip 13.
[0075] In one advantageous embodiment, the height "h" of groove
wall 200 is equal to the dimension "b" of condensation gutter
11.
[0076] FIGS. 16 and 18 provide a comparison of the assembly
dimensions of different seals. FIG. 16 shows sealing strip 10 for
beam section 2. FIG. 17 shows sealing strip 13 for the post
section; and FIG. 18 shows a combined sealing unit 13.1 for the
post section. FIGS. 16 through 18 are positioned relative to each
other so as to show that the glass support section 10 for the beam
sections including condensation gutter 11 has the same overall
height as the post seals in FIGS. 16 and 17.
[0077] The applicable formula is:
H=a+b.
[0078] In FIG. 18, the sealing strip or sealing strip 13.1 is of a
two-part design, i.e., it has a sealing strip 21, made of a sealing
material, and a rabbet reduction section 220 which is generally
made of the same material as the beam section and post section,
that is, for example, or preferably, of aluminum.
[0079] Rabbet reduction section 220 has a height b which in an
especially advantageous embodiment of groove wall 200 matches seal
10.
[0080] In this configuration, sealing strip 21 may run continuously
up to the groove rib or groove base 12 of sealing strip 10, the
seal base of sealing strip 21 along with condensation gutter 11
being removed in the overlap region. The drainage channel thus
produced is filled by filter insert (filling piece) 25, or sealed
by a filling piece.
[0081] This feature ensures that there is either a condensation
drain into seepage water groove 8 or a cavity under sealing strips
7, 9 of the post section.
[0082] FIG. 19 shows a part of sealing strip 10 into the end of
which a seal molding 230 may be inserted in the region of
condensation gutter 11. This seal molding 230 completes the
condensation gutter up to the upper sealing surface of sealing
strip 10, while simultaneously forming an exterior flush seal with
groove wall 20 such that the sealing strip of the post section
forms a smooth overall support surface ensuring a tight fit in the
overlap region between beam section 2 and post section 1. In this
case, sealing strip 10 is guided into the overlap region of the
sections without any additional sealing corner pieces or sealing
end pieces being required.
[0083] Seal molding 230 leaves a free channel free so as to allow a
punched hole in the base of condensation water groove 11 to be
accessible to drain the condensation.
[0084] Unlike the configuration in FIG. 19, seal molding 240 in
FIG. 20 has a continuous channel to allow the condensation to be
passed through into the seepage water intake of the beam section.
Filter insert (filling piece) 25, comprising a synthetic polyamide
filter medium, may be inserted into this exposed channel.
[0085] FIG. 21 against shows a facade intersection or region.
Sealing strip 10 is again guided into the overlap region so that
condensation gutter 11 comes to rest on the sealing groove of the
post section.
[0086] The closed attachment surface is formed by seal moldings
230, 240 and allows sealing strip 13 to form a tight seal against
sealing strip 10 or condensation gutter 11. The invention is also
suitable for cover designs.
[0087] FIG. 22 shows a steel post section 1001 and a steel beam
section 1002. Cover sections 1003 are mounted onto and attached to
steel post section 1001 and steel beam section 1002 so as to retain
and align the glass mounting seals, the cover sections
accommodating post cover seal 1004 and beam cover seal 1005. Cover
section 1003 may be made of steel, aluminum, plastic, or even
wood.
[0088] The insulating glass panes 1104 are attached by cover
sections 1101 for the post, and by cover sections 1102 for the
beam, as well as by retainers 1103.
[0089] Post cover seal 1004 has seepage water grooves 1006, 1007
which are delimited by the sealing wall enclosing the helical
groove of the cover section and by the wall of the glass mounting
region.
[0090] Post cover seal 1004 includes a seal base 1008 which is
mounted onto cover section 1003 via helical channel K, and extends
along the two outer sides of post section 1001 facing the
insulating glass pane and under insulating glass panes 1104 where
the seal base rests, supporting glass mounting regions 1009. Walls
1010 between each seal base 1008 below insulating glass pane 1104
and the region of seal 1004 located over cover section 1003 form
the groove base for seepage water grooves 1006 and 1007.
[0091] The glass mounting regions 1009 are connected to seal base
1008 by integral hinges 1105 along the longitudinal edges and are
thus easily detached from this base. In the separation level 1011
between seal base 1008 and glass mounting region 1009, a
form-fitting attachment--here a type of slot-and-key joint
1106--may be located up to the integral hinges on the edge in the
longitudinal axis of the sealing strand or sealing strip.
[0092] Walls 1010 forming the groove base for the seepage water
grooves are situated significantly below separation level 1011, but
are at least flush with this level. Walls 1010 are connected to
each other by additional sealing walls which enclose the helical
channel.
[0093] Beam cover seal 1005 is also of a one-piece design but has a
"two-piece" function," the seal base 1012 being designed as sealing
strips which are connected to glass mounting region 1013 by at
least one integral hinge on the longitudinal side. If needed,
form-fitting means--here of the type of slot-and-key joint
1106--are also provided in separation level 1011 to align the base
1012 on glass mounting region 1013. Besides integral hinge 1105,
there is no other connection between seal base 1012 and glass
mounting region 1013.
[0094] Glass mounting seal or cover seal 1005 has seepage water
grooves 1014, 1015. These grooves are formed by walls 1016 which
extend above separation level 1011 between glass mounting regions
1013 and the region of the seal covering helical channel K. The
lower level of walls 1016 is aligned with separation level 011 and
the lower wall of glass mounting region 1013.
[0095] In addition, on the outside, when viewing the beam section
in the installed position, there is a condensation gutter 1017
molded onto the glass mounting regions 1013 of the beam cover seal.
At least one such condensation gutter 1017 is provided, and
preferably two condensation gutters 1017 are molded on.
[0096] In the embodiment of FIG. 22, condensation gutters 1017
consist of three rectangular facing walls; the inner wall 1017a is
the outer wall of the glass mounting region, relative to which
another wall 1017b aligned with the lower side of separation level
1011 is perpendicular, onto which wall the outer wall 1017c
projecting vertically from wall 1017b is molded on.
[0097] The wall of condensation gutter 1017b forming the groove
base is flush with separation level 1011, that is, when
condensation gutter 1017 is present, the notch along post cover
seal 1004 need only be implemented along the entire width of glass
mounting region 1013 including condensation gutter 1017. Both
condensation gutter 1017 and seepage water grooves 1014, 1015,
including glass mounting region 1013, thus rest on seal base 1008
of post cover seal 1004.
[0098] As in FIG. 1, condensation gutter 1017 and seepage water
grooves 1014, 1015 here drain together into seepage water grooves
1006, 1007 of the post.
[0099] The embodiment of FIG. 23 essentially matches that of FIG.
22. In contrast to FIG. 22, however, post cover seal 1019 has a
cavity 1018 in the region of seal base 1020, which may be closed on
all sides, but which may also be partially open toward separation
level 1011.
[0100] This arrangement allows the condensation from condensation
gutter 1017 to drain into this cavity 1018. Post cover seal 1019 is
guided into the base region of a facade, or into the drainage
region of a light roof, thus providing a simplified means of
separate drainage for seepage water and condensation. Joining
cavity 1018 to condensation gutter 1017 is easily implemented by
punching through the groove base of condensation gutter 1017 in the
assembled state.
[0101] Glass mounting region 1013, including at least one
condensation gutter 1017, is positioned simply by notching glass
mounting region 1009 of post cover seal 1004, 1019. Depending on
the overlap of the beam cover seal on the post cover seal, seal
bases 1012, 1021 are back-notched from glass mounting region
1013.
[0102] FIG. 24 is a perspective view of a beam-post abutment in
which the backing comprises a so-called double-T-beam instead of a
hollow section. The condensation gutter 1017 is inserted in between
the corresponding notched post cover seal 1004, 1019 in the region
of glass mounting region 1009 and then tightly fitted onto glass
mounting region 1009.
[0103] Particularly because of the fact that condensation groove
1017 aligns with seepage water grooves 1014, 1015 of beam cover
seals 1005, 1021, that only notching of the post section is
required and the seal is readily ensured.
[0104] The two drainage water systems for condensation and for
seepage water are joined by condensation gutter 1017. To prevent
the exchange of air between interior air and the facade glass
rabbet, filling piece 1250 is inserted into the condensation groove
in the overlap region of the beam and the post, as in FIG. 25, the
filling piece scaling the opening formed between the condensation
gutter, the glass pane, and the adjacent glass mounting seal of the
post section.
[0105] Filling piece 1250 comprises a material which prevents the
passage of air, while allowing condensation to pass through and
discharge into the seepage water region of the post sections.
[0106] FIG. 26 shows an extruded-on condensation gutter 17 of the
type shown in FIG. 25. Here again, the transition from the
condensation gutter to the seepage water drain or rabbet of the
post section is effected by a sealing adapter 1240 which is
inserted into the condensation groove in the overlap region between
the beam and the post. This scaling adapter 1240 has a tunnel-like
channel 1500 into which filling piece 25 is again inserted to
prevent the passage of air into the rabbet base of the facade,
while still allowing condensation liquid to pass through into the
seepage water region of the post.
[0107] Sealing adapter 1240 is preferably made of the same material
as the seals themselves in order to ensure sealing against the
glass in the region of the condensation passage. As with filling
piece 1250 in FIG. 25, filling piece 1025 functions to prevent the
exchange of air and the passage of condensation.
[0108] FIG. 25 shows filling piece 1250, the shape of which is
adapted to match the condensation opening to be sealed.
[0109] Filling piece 25 in FIG. 27a comprises parallel joined
fibers 1251 which are aligned in the longitudinally parallel axis
of the condensation gutter. Capillary openings are formed between
the fibers which cause the liquid condensation to move along the
fiber surfaces due to capillary action and adhesion.
[0110] Alternatively, hollow fibers 1252 may also form the body of
the filling piece, the capillaries being provided both by the space
between fibers and by the hollow fibers themselves.
[0111] FIG. 27b shows a filling piece 1025 made of chaotically
joined fibers into which individual fibers have been interwoven or
felted. Here again, the liquid condensation moves by adhesion to
the fibers, and also by capillary action, into the drainage level.
The fibers may preferably consist of fiberglass, polyamide fibers,
or the like.
[0112] Use of these filling pieces is appropriate for all facade
designs in which condensation is combined with the seepage
water.
[0113] In the event filling pieces 25, 1025 do not have sufficient
elasticity to allow them to be appropriately adapted to the sealing
pressures of the glass mounting seal, provision is made to locate a
sealing pad or sealing strip 1253 on the side of the filling piece
facing the glass pane.
