Abstract

The invention relates to a sealing strip for a façade or a roof comprising a metal framework. The vertical member profiles and the cross member profiles comprise sealing grooves (5, 6, 9) for sealing strips (10, 13, 13.1) and, preferably, receiving grooves (8) for leakage water. The bottoms of said sealing grooves (5) for the sealing strips (10) and, preferably, the bottoms of the receiving grooves (8) for the leakage water of the cross member profiles (2) rest on the sealing grooves (6, 9) of the sealing strips (13, 13.1) of the vertical member profiles (1). The sealing strips (13, 13.1) of the vertical member profiles are higher than the sealing strips (10) of the cross member profiles in such a way that said sealing strips occlude in a common plane, at least one sealing strip (10, 13, 13.1) of the cross member profile or the vertical member profile comprising a single-part drainage channel (11, 18) which is formed on a glass supporting area (10a) of the seal by means of a web (10c), said drainage channel having an essentially rectangular, u-shaped cross-section.

Description

Sealing strip for facade and/or roof

Technical Field

The present invention relates to a sealing molding for roofs and/or roofs with a metal frame structure, and more particularly to a glass-bearing sealing molding for roofs and/or roofs with a metal frame structure, the frame area of which is preferably provided with insulating glass panels.

Background

Although the construction of facades and light-transmitting roofs for wales/uprights (Riegel/Pfosten) and the thermal insulation of glass panels and wall panels for balconies are improved, the interception of condensation and its removal in the edge regions of the panels is of particular importance.

In particular in the case of sloping roof surfaces or facade surfaces sloping to the horizontal, interception and drainage of condensation water in the region of the underlying sloping surfaces is necessary. The majority of the horizontal or inclined cross-brace profiles are those which are exposed to the draining or dripping condensation water.

The same german patent DE 3419538 describes a facade and a roof of a metal-glass structure, wherein the vertical column profiles and the cross-brace profiles each have a condensate trough arranged along both sides of the side edges.

The level of the condensate trough is arranged such that, when the cross-brace profile is connected to the vertical column profile, the trough bottom of the condensate trough of the cross-brace profile rests on the trough-delimiting walls of the condensate trough of the vertical column and thus transfers condensate from the cross-brace profile into the vertical column profile and then together along the condensate trough of the vertical column is removed at a suitable point. The condensate trough of the vertical column profile by means of the overlapping principle leads without restriction to the floor area or to a drainage area of the roof.

It has proven to be less than ideal for the design in which the width of the transverse strut and vertical strut profiles must be greater than that which would be required by the glass support technology, since the respective condensate water channel must also form a partially open channel which projects in the vertical direction beyond the glass support region.

This means more material consumption and more visible surface for the profile, which in turn increases the costs for the coating. The wider profile also runs counter to the desire for architecture to develop into the appearance of the narrower profile.

In order to overlap the condensate trough of the cross brace on the vertical column, additional socket machining is required on the cross brace profile, which is a special requirement for the remachining points and leads to considerable additional costs.

Disclosure of Invention

The object of the invention is to provide a simple and reliable condensate collection and removal measure which can be adapted to the structural width of the metal vertical column profile and the metal cross brace profile.

To this end, the invention proposes a sealing strip for facades and/or roofs with a metal frame construction, in which: the metal framework is provided with vertical column profiles and cross-bracing profiles which are positioned with the vertical column profiles; the vertical column section and the transverse strut section are provided with sealing grooves for sealing insertion strips, and insulating glass plates can be supported on the sealing insertion strips; the vertical column section bar and the cross brace section bar are also provided with accommodating grooves for water leakage; the bottom surface of the sealing groove of the sealing embedded strip for the cross-bracing section bar and the bottom surface of the containing groove for the water leakage of the cross-bracing section bar are supported on the sealing groove of the sealing embedded strip for the vertical column section bar; the single or combined sealing strip of the vertical column section has larger structural height than that of the sealing strip of the cross-brace section, so that the sealing strips of the cross-brace section and the vertical column section are in end connection in the same plane; characterized in that at least one sealing fillet of the cross-brace profile has a condensate trough formed in one piece via a strip in a sealed-off glass support region, which has a substantially right-angled U-shaped cross section; the glass support region has a height "a" from the plane X, i.e. the upper edge of the sealing groove, while the water spout has a dimension "b" from the plane X up to the lower edge of the spout bottom, wherein the dimensions a and b are selected such that the spout bottom of the spout rests on the upper edge of the sealing groove of the mullion profile.

In this case, at least one or more sealing strips of the transverse strut profile and/or vertical column profile have a drainage channel which is formed in one piece in a sealed glass support region, is used in particular for condensation water and has a substantially right-angled U-shaped cross section.

Since the condensate trough is surprisingly no longer arranged on the metal profile but is arranged on the sealing strip in a simple and cost-effective manner, it is possible to flexibly adapt to the building situation, in particular to the place where the facade is in an inclined and horizontal area, namely: access to the translucent roof area or to a place where special condensate generation is considered. With a corresponding shaping, the sealing strip according to the invention can also be reliably removed for a high condensate yield.

The condensate trough of the sealing strip is designed at right angles in a good-looking and practical manner and is preferably dimensioned in accordance with the subject matter of the other dependent claims in such a way that it is in a particularly advantageous state with the remaining sealing strip of the upstand profile.

It is also possible with the sealing strip according to the invention to use the same profile combination in the vertical facade area and in the horizontal light-transmitting roof area.

Seals made of elastic material are trimmed with simple tool knives and scissors and ensure a high degree of tightness without special requirements for further processing.

The condensate water tank on the sealing embedded strip of the cross support compensates the height difference of the sealing element towards the vertical column direction in appearance.

Highly accurate length trimming of the seal is not required as slight excesses of the seal can be elastically eliminated along the entire length by compression. Even small overlengths of the seals, in particular of 1 to 2%, make it possible to seal the interfaces between the seals and between the corner and end fittings more elastically.

In particular, for straight inclined surfaces with horizontal cross-brace profiles, a minimum of one cross-brace sealing strip with a condensate trough is sufficient. Such seals are mounted on the upper side of the wale profile to the rising surface and are generally sufficient to drain and contain the condensate. In the case of possibly low barrier glasses or panels or also in the case of more flatly pitched roof structures, it may be necessary to provide the surrounding racks or condensate retaining grooves on at least three sides.

The sealing strip with the condensate trough can be used wherever condensate generation is concerned, in particular under inclined glass panes and panels, where the condensate is drained in the direction of the cross-brace profile.

A tight sealing plane and glass support can be formed by simple means by the attachment described in detail below.

Since the condensate sump is cost-effective and is formed in one piece on the sealing strip in a manner which is not difficult to assemble in practice, no assembly work is required even with an accessory, although the invention can be supplemented by further accessories of specific utility according to the dependent claims.

Furthermore, it has proven advantageous: the condensation water tank of the cross brace section bar directly or indirectly extends to the glass supporting area of the vertical column section bar, and water is drained into the groove of the vertical column section bar. In this way the advantageous drainage technique as one of the same prior art is substantially maintained, while the number of elements of the wale profile is reduced.

Detailed Description

Fig. 1 shows a part of the facade of a metal-glass structure with a metal frame framework consisting of vertical column profiles 1 and cross-brace profiles 2 positioned perpendicularly thereto, wherein the cross-brace profiles are mounted on the vertical column profiles 1.

The vertical column profile 1 and the transverse strut profile 2 each have a central web 100 at the end face, which serves for fastening the cover shell 101. The cover case 101 fixes a spacer such as a glass plate, for example, an insulating glass plate 102.

The transverse strut profile 2 is of a bayonet-type design at the end face, and the profile wall 3 facing the insulating glass pane is supported in the installed state on the sealing groove 6 of the vertical column profile 1, wherein the profile wall 3 forms the bottom for the water drain channel 4 and the sealing groove 5.

The sealing groove 6 of the vertical pillar profile 1 is located above a cavity 7, as seen from the building side of the facade. The sealing groove 6 and the cavity 7 together define a water leakage channel 8 of the upstand profile 1.

According to the embodiment shown by way of example on the right-hand side of the vertical column profile 1 in fig. 1, the sealing groove 6 on the vertical column profile 1 is also configured to be open downward, so that the sealing groove 6 extends up to the region of the cavity 7 and the sealing groove 6 can be said to function as a sealing groove together with the cavity 7 and merge into a sealing groove 9 which is combined with the cavity.

The sealing bead 10 of the transverse strut profile 2, which has its own glass support region 10a and sealing base 10b, advantageously has a condensate sump 11, preferably in the form of a right angle, which is formed in one piece in the glass support region 10 a.

The condensate sump 11 adjoins the outer surface of the cross-brace profile 2 with the wall of the seal facing the sealing bead 10 in a tightly closed manner, and the sump bottom 12 terminates with its lower face flush or aligned with the lower face of the profile wall 3. In principle, the condensate sump 11 may also have any different shape, for example a circular cross-sectional form, although a right-angled corner form is preferred for reasons of appearance and stability. It is important that the cross-sectional dimensions of the groove are dimensioned such that a sufficiently large drainage volume and sufficient stability can be achieved. Furthermore, although the individual properties of the sealing strip 10 are particularly advantageous, a modular embodiment of the sealing strip is also possible in principle.

The sealing strip 10 passes right into the area of the sealing strip 13 of the vertical column 1 and is supported there on a sealing angle 14, to which the glass support seal 13 of the vertical column 1 is also connected or mounted.

The sealing angle 14 has a projection 15, which is directed toward the sealing bead 10 of the transverse strut profile 2 and which corresponds to the condensate sump 11, and which surrounds and thus supports and positions the condensate sump 11 laterally and from below.

The sealing corner fitting 14 comprises a condensate sump facing the cross-brace profile, which in the aligned region of the sealing web 13 opens into a closed hollow channel, which leads from an outlet 16 downwards and opens into the cavity 7 through the sump bottom 17 of the sealing groove 6. Alternatively, the outlet 16 opens into a sealing groove 9 which is open towards the bottom. In this case, the outlet 16 in the sealing angle 14 can also be omitted, so that there is only one drainage bore in the sealing body of the sealing angle 14.

In the new sealed facade structure shown in fig. 1, a structurally simple, low cost condensate drainage system is provided which functions reliably and separately from the leakage drainage system of the leakage basins 4 and 8.

Fig. 2 shows a roof construction in which the vertical column profiles and the transverse strut profiles 1, 2 are unchanged from fig. 1. But in addition to fig. 1: the sealing strip 21 of the vertical column profile 1 likewise has a condensate sump 18 formed directly in the glass support region of the sealing strip, which in turn is engaged and supported around the projection 19 of a sealing angle 20.

The sealing angle 20 comprises a foot pattern which engages both in the sealing groove 5 of the cross-brace profile and in the sealing grooves 6, 9 of the vertical columns and is fixed there in a form-fitting manner.

The fillet seal 20 also has an elongated condensate trough passage in the direction of the alignment of the condensate trough 11, which passes through the fillet seal 21 aligned side of the fillet seal.

In this way the guttering 8 of the upstand is in direct communication with the condensate drainage system, i.e. the condensate is drained directly into the drainage system.

The sealing angle 20 may have a drainage projection 22 in the direction of the sink 8.

According to fig. 2, the drainage systems for the condensate and the leakage are therefore no longer separate but are combined to form an overlapping system.

It is also possible in this case to achieve a minimization of the air exchange between the leakage water sump 8 and the condensate sumps 11, 18. For this purpose, a fiber-type filter element 25 (described later) is inserted into the passage of the condensate sump 8 connecting the condensate sump to the vertical column, which filter element prevents air exchange, but on the other hand, the condensate water produced by the adhesion and capillarity of the filter material is discharged into the drain system.

The two different drainage systems of fig. 1 and 2, i.e. the combined drainage system or the separate drainage system, and the arrangement of the condensate sump 18 on the sealing strip 21 can be used or exchanged as desired.

The sealing strip 10 for the wale profile 2, which is provided with the condensate sump 11, should be arranged at least above the wale profile in the inclined surface. In the case of a slight slope of the roof or facade surface, the seal can also be arranged on both sides of the wale profile. The same is true for roof surfaces where condensation water produced by the condensate trough can emerge, cover the upper side of the wale profile and be drained away.

The construction and function of the facade drainage system will be described in more detail below with the aid of further figures.

Fig. 3 shows a top view of the section intersection point of the vertical column 1 and the transverse strut 2. A sealing fillet 21 with an integrated condensate sump 18 is located on the upstand 1. The sealing strips 10, 21 are connected by a sealing angle 20. The condensate sump 11, 18 is surrounded and supported by the projection 15, 19, wherein a corresponding sealing is also achieved. Furthermore, a correspondingly enlarged adhesive surface for joining the sealing and sealing of the corner joint is provided.

Fig. 3 shows the separated drainage of the leakage water to the space 9 or the cavity 7 under the sealing strip 21. A drain channel 23 is also visible, which leads to the outlet 16 at the extension of the condensate sump 11 in the sealing angle fitting 20.

Fig. 4 shows, in contrast to fig. 3, a sealing bead for a vertical column 1 without a condensate trough or a glass support seal 13 there.

Figure 5 shows a top view of a roof surface according to the version of figure 2. In the top view of the profile intersection, the drainage channel 24 can be seen particularly well, which is aligned with the condensate trough 11 and leads to the drainage trough 8 of the upstand 1. The drainage channel is filled with a filter cartridge 25 which substantially prevents air exchange between the drip channel 8, also called sump cavity, and the condensate channel, also called internal cavity. Only the condensed water drains into the channels formed by the fibres by adhesion and capillary action on the fibres.

Fig. 6 essentially corresponds to the embodiment according to fig. 1, except that the sealing bead 13 forms a condensate-free water channel and, as shown in fig. 5, the water discharge takes place via the water discharge channel 24 and the inserted filter cartridge 25.

According to fig. 7, only the sealing bead 13 is inserted into the vertical column 1. The sealing strip 10 with the condensate sump 11 adjoins a sealing end connection 26, which lengthens the cross-brace seal 10 up to the area of the upright profile 1. The sealing end fitting 26 engages with a foot formation in the sealing groove 5 of the cross-brace profile and is fixed there, as it were, to the seal 10. The width of the seal end fitting 26 corresponds to the overall width of the sealing band 10, including the condensate sump 11, so that the seal 13 can abut the outside of the seal end fitting 26 tightly under bias at the end face. The sealed end fitting 26 may be connected to a drain passage 27 in front of the condensate tank 11 in the condensate tank extension. The drain channel 27 leads to an outlet 16, which in turn leads the condensate, separated from the leakage water, into the space 9 or cavity 7 of the vertical column profile.

Fig. 8 shows, like fig. 7, the intersection of a vertical column profile 1 with a cross-brace profile 2. A sealing end connection 28 is shown, which is arranged in the overlapping region between the cross-brace profile and the vertical column and whose drainage channel 27 opens into the drainage channel 8 or the recess of the vertical column profile. Such a sealed end fitting 26 is also particularly suitable for use with cross-brace profiles that are joined at an angle, since the sealed end fitting 26 can be cut according to the angle of engagement of the profiles.

The sealing end fitting 26 has a smooth surface in the direction of the sealing bead 13, on which the glass carrier seal 13 can be mounted in a tightly closed manner. The drain channel 27 is provided with the filter cartridge 25 as shown in fig. 5 and 6.

Fig. 9 and 10 also show the relationship that the sealed end fitting 26 is used in particular for intersections in which the wale profile 2 is connected to the upstand profile at an angle. For this purpose, the sealing end fitting 26 is made longer than is necessary for a right-angle connection, in order to be able to adapt to changing conditions in the simplest possible manner.

Fig. 9 shows the inclined connection of the already mentioned cross brace profile to the vertical strut profile and corresponds to fig. 7 described above. Only the sealing end fitting 26 and the sealing bead 13 are adapted to the connection angle of the profiles.

Fig. 10 shows a top view of the inclined interface of the wales and upstands and otherwise consistent with the description of fig. 8. Only the seal end fitting 28 and the seal bead 13 of the upstand are matched at the angle of intersection.

Fig. 11 shows an exploded perspective view of the structure of the cross-brace upstand connection on the roof side. The cross-brace profile 2 overlaps the vertical column profile 1 in the region of the sealing groove. The height compensation occurs due to the different heights of the seal 10 and the seals 13, 13.1. This difference in height can be compensated in particular by the sealing angle joint 14. A sealing fillet 14 and a sealing fillet without a condensate sump 18 according to fig. 2 are shown. The sealing angle 14 is particularly clearly visible. The sealing angle connections each have on their side edges centering projections 29, 30, 31 in the region of the interface with the respective sealing bead 10, 13, which cooperate with the corresponding cavity of the glass carrier profile and engage in it in order to fix the mutual position of the individual components. The projections also form enlarged contact surfaces for possible adhesion of the components to one another.

At the sealing angle 14 or also at the sealing angle 20, either the drainage outlet 16 or the drainage projection 22 is provided, which has a drainage channel 27 closed by the filter cartridge 25.

Figure 12 also shows an exploded perspective view of the cross-joint of the front face of a wale/mullion. In this figure, the sealed end fitting 26 is shown, which likewise has a centering projection 29, which cooperates with a cavity of the glass support profile 10. The glass support profile 13 is elastically supported on the outer surface of the sealing end fitting 26.

The sealed end fitting 26 is provided with the outlet 16 for separately discharging the condensed water or with the drain passage 27 and the filter cartridge 25 in the case of collecting and discharging the condensed water together with the leaked water.

Fig. 13 shows a sealing angle joint 14, typically also for a sealing angle joint 20, which can be seen from the above-mentioned details. Instead of the drainage channel 27 and the sealing core 25 shown, the sealing angle joint is equipped with an outlet 16 for separately draining off the condensate.

The same is true of the sealed end fitting 26 shown in fig. 14.

Instead of a fillet or a bead, the fillet 10 together with the condensate sump 11 can be led up to the overlapping region (not shown) of the cross brace 2 and the vertical column 1. The sealing strip 13 of the vertical column profile is then guided with a preload force to the outside of the condensate sump 11, wherein a connection piece is inserted in the condensate sump 11 in the region of the sealing strip 13, which connection piece on the one hand compensates the structural height up to the glass support and closes the condensate sump 11, so that the condensate can be drained into the space 9 or the chamber 7 below the sealing strip 13 by means of a perforation in the sump floor of the condensate sump 11.

The adapter piece may also constitute a channel in which a filter cartridge 25 is arranged, which effects the drainage into the recess or sink 8.

In the embodiment described at the end, in particular, but also in the embodiments according to fig. 7, 8, 9, 10, 12 and 14, which all involve sealed end connections 26, the height compensation between the cross-brace profile and the vertical strut profile for the glazing support plane can also be achieved by a two-part vertical strut seal 13 (see fig. 18). In particular, it is conceivable to use a combination of an aluminum bottom molding and a corresponding sealing molding 10 without a condensate sump.

The construction of the bead or particularly the bead having a drain channel mounted or formed thereon will be described in more detail below.

Fig. 15 shows an enlarged cross section of the sealing strip 10, which is supported with its plane X on both upper edges of the sealing groove 5 and is positively fixed in the wale profile 2 by means of a sealing foot. A web 10c is connected to the sealing body, i.e. to a glass support region 10a which is formed in a substantially known manner and has a shaped sealing foot 10b for engagement in the sealing groove 5, wherein the sealing foot 10b and the glass support region 10a (not shown) can also be connected to one another in a folded-over manner by means of a film hinge, so that the glass support region can be easily separated from the foot region in the overlap region with the vertical column profile, and the web 10c is formed directly laterally on the glass support region 10a and has substantially the height of the glass support region 10 a. A stabilizing web 10c overlaps the outer edge of the sealing groove 5, the sealing groove 5 being open on one side in the direction of the insulating glass pane, and a condensate trough 11, which is rectangular and forms an essentially "U" and is formed by the trough walls 12, 200 and the trough bottom 130 and is supported on the cross-brace profile 2 with its side pointing toward the cross-brace profile 2, is also formed on the stabilizing web 10 c. The plane Y of the groove wall 12 pointing towards the sealing body thus forms a lateral fixing and bearing plane on the cross-brace profile 2.

The sealing body or glass support region 10a has a height "a" from the plane X, i.e. from the upper edge of the sealing groove 5, while the water drain channel has a dimension "b" from the plane X up to the lower edge of the channel bottom 130. The effective structural height "H" of the sealing strip 13 for the vertical column profile 1 is composed of the height of the glass support region and the dimension "b" of the gutter, i.e. the sum of "a + b".

The dimensions a and b are selected such that the groove bottom 130 of the sink is supported on the upper edge of the sealing groove 6 of the upstand profile. Wherein the groove wall 200 is also perpendicular to the groove base 130 and in a particular exemplary embodiment forms part of the bearing surface for the sealing bead 13.

In an advantageous embodiment, the height "h" of sump wall 200 is equal to the dimension "b" for condensate sump 11.

Figures 16 to 18 enable comparison of the mounting dimensions of the various seals. Fig. 16 shows a sealing strip 10 for a transverse strut profile 2, fig. 17 shows a sealing strip 13 for a vertical column profile, and fig. 18 shows a combined sealing unit for a vertical column profile. With the side-by-side positioning of fig. 16 to 18, it can be seen that the glass support molding 10 for the cross-brace profile, including the condensate trough 11, has the same structural height as the upstand seal according to fig. 16 and 17.

Therefore, H is a + b

According to fig. 18, the combined sealing unit or sealing strip 13.1 is formed in two parts, namely it has a sealing strip 21 made of sealing material (the integrated condensate sump 18 is not shown here) and a groove reducing profile 220, which is generally made of the material of the cross-brace profile and the vertical column profile, and is therefore made of aluminum, for example or preferably.

In this respect, the groove profiles 220 have a height b which corresponds to the case in a particularly advantageous configuration of the groove wall 200 of the seal 10.

In this case, the sealing strip 21 can be a groove web or groove bottom of the sealing strip 10, the sealing foot of the sealing strip 21 being remote from the overlapping region with the condensate sump 11. The drainage channels thus formed are filled with filter cartridges 25 or are closed by a sealing block. This ensures that the condensate drains into the drainage channel 8 or into the chambers 7, 9 below the sealing strip of the vertical column profile.

Fig. 19 shows a section of the sealing bead 10, in which a sealing profile 230 can be inserted at the end face into the region of the condensate sump 11. The sealing profile 230 supplements the condensate water channel as far as the upper sealing surface of the sealing bead 10 and simultaneously terminates flush on the outside with the channel wall 200, so that the sealing bead of the vertical column profile in the overlapping region between the transverse strut profile 2 and the vertical column profile 1 forms a smooth overall bearing surface for a tight seal. In this case, the sealing strip 10 opens up into the overlapping region of the profiles without additional corner or end sealing joints being necessary.

The seal 230 is provided with a passage to allow it to pass through a hole in the bottom of a condensate tank 11 for draining condensate.

According to fig. 20, the sealing profile 240 differs from that of fig. 19 in that it has a through-channel, so that the condensate can be guided directly into the water-leaking receiving groove of the wale profile. A filter cartridge 25 made of synthetic Polyamide (PA) filter media may be inserted in the unrestricted passage.

Fig. 21 again shows a facade intersection or region. The sealing strip 10 also opens into the overlap region, so that the condensate sump 11 is supported on the sealing groove of the vertical pillar profile.

The sealing profiles 230, 240 form a closed bearing surface in order to hold the sealing bead 13 tightly against the sealing bead 10 or the condensate sump 11.

The sealing strip according to claim 1, characterized in that a sealing profile (230) can be inserted into the sealing strip (10) of the cross-brace profile in the region of the condensate sump (11), which sealing profile (230) enlarges the condensate sump (11) up to the upper sealing surface of the sealing strip (10) of the cross-brace profile and terminates flush with the outer surface with the sump wall (200).

9. The sealing strip according to claim 8, characterised in that the sealing profile (230) is provided with a passage for the passage of condensate to a bore in the floor of a condensate trough (11).

10. Sealing strip according to claim 8, characterized in that the sealing profile (240) has a through-channel, so that condensate can be conducted directly into the water-leaking receiving groove of the cross-brace profile, and in which a filter cartridge (25) made of synthetic Polyamide (PA) filter medium can be inserted.

11. The sealing strip according to one of claims 8 to 10, characterized in that a closed bearing surface is formed by means of the sealing profile (230, 240) in order to hold the sealing strip (13) tightly against the condensate sump (11).

12. Sealing strip according to one of claims 1 to 3, characterized in that the sealing strip (10) of the transverse strut profile extends all the way into the overlapping region of the transverse strut profile and the vertical column profile, so that the condensate sump (11) is supported on the sealing groove of the vertical column profile.
