Description

DESCRIPTION

Sealing profile and structure of crossbars and uprights

The present invention relates to a sealing profile for a stud and post structure according to the preamble of claim 1.

EP 2444566 A2 describes an overlapping seal for a stud-and-post structure, in which a central section can be fixed to a threaded groove of a stud or a stud. The overlapping seal has several overlapping seals on opposite sides which can be removed in the area of an intersection. This allows drainage to take place via a drainage channel between a seal and the intermediate section from a stud to a stud. The bottom of the stud drainage channel is arranged in a different plane than the bottom of a stud drainage channel. This means that different sealing profiles must be provided when assembling a stud-and-post structure. Although this change in levels ensures safe drainage, its installation is complicated by the different sealing profiles.

DE 299 15574 discloses a facade with a sealing profile in a threaded groove of a support profile. The sealing profile has two sealing strips on opposite sides, which are connected with a central section around the screw channel.

Therefore, the objective of the present invention is to provide a sealing profile and a stud-and-rail structure that ensures reliable drainage at an intersection of a stud-and-rail structure and allows easy installation.

This objective is solved with a sealing profile with the characteristics of claim 1 and a structure of crossbars and uprights with the characteristics of claim 4.

The sealing profile according to the invention comprises a central section with a U-shaped cross section, which can be mounted in a threaded groove of a post or crossbar, with a first rib and a second rib, the first rib being connected to a first sealing strip which can be supported on the post or crossbar. On each leg, a second rib projects essentially perpendicularly from the leg, which is connected to a second sealing strip, so that in the area of a connection, a drainage can be realized along the second sealing strip, which forms the bottom of a drainage channel.

The two ribs, which are each connected to a sealing strip, can be provided with notches on the first sealing strip of the first sealing profile and on the second sealing strip of the second sealing profile, in particular at the intersections, which ensures effective assembly and reliable drainage. The first sealing strip and the second sealing strip can only be connected to each other indirectly via the ribs, so that the sealing strips, which can be placed at a distance, can be easily cut. In this way, one of the two sealing strips can be easily cut with a tool at the intersection.

According to the invention, the first rib is connected to the leg or the second rib on the side opposite the first weatherstrip and can be easily separated together with the first sealing strip to form a recess.

In a first embodiment according to the invention, the first rib and the second rib are connected to one another via a connecting rib, the connecting rib, the first and second ribs and a section of the leg enclosing at least one hollow chamber. The sealing profile thus has a higher dimensional stability in this region. Alternatively, in a second embodiment according to the invention, the first rib can be supported against the second rib via at least one support projection. Such a support projection can surround at least one hollow chamber with the first and second ribs. Via the support projection, the two sealing strips can be arranged at a distance without destroying the connecting rib in order to cut one of the two sealing strips in the region of an intersection.

Preferably, a sealing rib is arranged between the first sealing profile and the second sealing profile. The sealing rib may preferably have a rectangular cross section, the sealing rib optionally being formed integrally with the first or second sealing strip. This sealing strip can be removed at an intersection, for example, to insert a crossbar end piece in the region of the sealing rib in order to support an end section of the second sealing strip on the crossbar end piece.

Preferably, the weather strips have a greater thickness than the ribs, with the first weather strip projecting from the first rib towards the upright or cross member and the second weather strip projecting in the opposite direction from the second rib. The second rib thus forms the bottom of a groove between the second weather strip and the leg of the centre section. Preferably, the first rib is aligned substantially parallel to the second rib and is arranged at a small distance, for example less than 8 mm, for example between 1 mm and 6 mm.

The sealing profile is preferably used in a post-and-beam or post-and-beam construction, whereby the posts and post-and-beams are made of extruded aluminium profiles, plastic profiles, steel profiles or composite materials, for example a timber structure with an overlay profile or a steel structure with an overlay profile. A first sealing profile is attached to the post and a second sealing profile to the post, which are preferably designed with the same cross-section.

According to the invention, the second rib of the second sealing profile on the transom is arranged substantially in the same plane as the second rib on the first sealing profile on the upright. In this way, a common sealing plane is formed by the second ribs on the transoms and uprights, which is arranged substantially in one plane throughout the entire upright and transom structure. This eliminates the need to provide different sealing profiles that result in different sealing levels for drainage.

Preferably, the second sealing profile is cut into an end section that projects towards the post, with the first sealing strip and the first rib being removed in the area of the end section. In addition, the first sealing profile can have a recess in the second sealing strip at an intersection, into which the end section of the first sealing profile is inserted. In this way, a drainage channel, which is formed by a slot through the middle section, the second rib and a wall of the second sealing strip, can be led to a drainage channel in the other sealing profile. In this case, the end section of the second sealing profile can, if necessary, at least partially overlap the second rib of the first sealing profile of the post. Due to the elastic design of the sealing profile, the second rib of the second sealing profile can seal against the second rib of the first profile and ensures a secure seal even in the area of an intersection. The overlap can be, for example, between 1 mm and 4 mm in the longitudinal direction of the sealing strip. Optionally, the second rib on the first sealing profile can also be arranged abutting the second rib of the second rib of the second sealing profile.

In order to support the second sealing profile on the cross member in the area of an intersection, in particular in an end section, a cross member sealing piece, in particular with a substantially T-shaped cross section, can be inserted into the recess of the first sealing profile. The cross member sealing piece can have lateral ribs which are arranged between the first sealing strip on the first sealing profile in the area of the recess and the second sealing strip on an end section protruding into the recess. The cross member end piece can have a block or thickening in a central area which is arranged in the extension of a threaded groove of the cross member. A retaining element or spring which protrudes into the threaded groove is then preferably spaced out in the central section of the protruding end section so that the block can support the end section.

Preferably, the first sealing profile and the second sealing profile have the same cross section, so that the same sealing profiles can be used for all intersections where the crossbars and the uprights meet, which facilitates installation. The sealing profiles are cut to obtain a recess or a protruding end section, the part of the sealing profile to be removed being then preferably joined in the longitudinal direction via predetermined breaking points, so that it can be removed in the longitudinal direction and removed without a cutting tool.

In a preferred configuration, the first rib is formed on one of the legs of the central section and projects essentially perpendicularly from the leg and is therefore aligned in parallel with the second rib.

Alternatively, the first rib may be formed into the second rib and have an essentially angular cross section, such that the first rib and the second rib are designed in a "Y" shape and are formed into the leg of the center section.

In the sealing profile according to the invention, the first and second sealing strips are preferably designed in such a way that a loose adjacent profile is formed on the adjacent side of the sealing strips, which allows the two sealing strips to be displaced perpendicularly or laterally to the longitudinal direction and parallel to the plane of a filling element, such as an insulating glass pane. This profiling can be formed, for example, by projections, strips, grooves, notches or ribs. Since the two sealing strips only fit together loosely, one of the two sealing strips can easily be removed, for example at intersections.

The invention is explained in more detail below by means of an exemplary embodiment with reference to the accompanying drawings. It is shown in:

Figure 7, a sectional view of another embodiment of a sealing profile, and

Figure 8, a sectional view of another exemplary embodiment of a sealing profile.

A mullion-and-transom structure 1 comprises vertical mullions 2, which are connected via horizontal mullions 3 or mullions 3' oriented at an angle to the vertical. The size of the individual fields within mullions 2 and mullions 3 can be freely designed depending on the façade, although the mullion-and-transom structure can also be used for pitched lightweight roofs. At the intersections between mullions 2 and mullions 3 it is possible to create drainage, which is formed by channels on sealing profiles.

Figure 2 shows a section through a post 2 or crossbar 3, which is fastened as a profile on top of another profile made of steel, wood or other material. The post 2 or crossbar 3 includes a threaded groove 4 which projects vertically from a plate-shaped rib 5. Hooks 6 are formed on the plate-shaped rib 5.

The upright 2 or crossbar 3 is attached to a sealing profile 10, which has a U-shaped central section 11. A fixing element 9 is formed in the central section 11, which is inserted into the threaded groove 4. The central section 11 has two legs 12 which run parallel to each other and which surround the walls of the threaded groove 4.

On each leg 12, a first rib 13 projects essentially vertically, on which a first weatherstrip 14 is formed. The weatherstrip 14 rests on the upright 2 or crossbar 3 and is fixed to the hook 6.

A second rib 15 also projects essentially vertically from the leg 12, on which a second sealing strip 16 is formed. The two sealing strips 14 and 16 have a greater thickness than the ribs 13 and 15. As a result, the first sealing strip 14 projects from the upright 2 or crossbar 3 and the second sealing strip 16 projects from the second rib 15 to a surface element that is not shown, for example an insulating glass.

A sealing rib is arranged between the first sealing strip 14 and the second sealing strip 16, which is preferably integrally formed with one of the two sealing strips 14 or 16, in particular via a seal on the outside of the respective sealing strip 14 or 16. The sealing rib 17 has a smaller thickness than the sealing strips 14 and 16. The structure of the two sealing strips 14 and 16 with the sealing rib 17 has, for example, a height h of between 12 mm and 30 mm, in particular 14 mm to 19 mm. The total height H of the overlapping profile with the central section 11 is, for example, between 20 mm and 40 mm.

The first rib 13 and the second rib 15 are connected to each other via a connecting rib 18. This creates a hollow chamber 19, which is formed by a part of the leg 12, a part of the ribs 13 and 15 and the connecting rib 18.

The sealing profile 10 is preferably configured symmetrically with respect to a central plane through the threaded groove 4 and can be made of an elastic material, for example EPDM, for example by extrusion.

Figure 3 shows a first sealing profile 10 on a post 2, not shown, and a second sealing profile 10' on a cross member 3, not shown, in the area of an intersection. The sealing profiles 10 and 10' have the same cross-sectional shape, so that reference is made to the previous embodiments on the design of the sealing profiles 10 and 10'.

The sealing profile 10 on the post 2 has a recess 20 which is obtained by cutting the second sealing strip 16. In the area of the recess 20, the first rib 13 is not cut with the first sealing strip 14. Preferably, the second rib 15 is not cut or at least only slightly, in particular less than 20% of its width.

The sealing profile 10' fixed to the crossbar 3 has a cut-out end section 21 on the side facing the sealing profile 10. The sealing profile 10' has no first sealing strips 14 or ribs 13 in the end section 21. The end section 21 with the second sealing strips 16 and the ribs 15 can thus be inserted into the recess 20 to form the groove drainage with the rib 15 acting as a groove bottom in the groove of the sealing profile 10.

In order to support the end section 21, a cross-sectional T-shaped transom sealing piece 22 is provided. A block 23 is arranged in an extension of the threaded groove 4 of the transom 3, from which lateral ribs 24 project on both sides of the block 23, which at the end have an angle 25 which can optionally be omitted. The lateral ribs 24 are arranged on the sealing strip 14, the lateral ribs 24 having approximately the same thickness as the sealing rib 17, so that the second sealing strip 16 in the sealing profile 10' runs essentially in the longitudinal direction in the end section 21 without bending. The transom sealing piece 22 can be made of an elastic or dimensionally stable material, although different materials can optionally be used. The cross member sealing piece can be glued to the end section 21 or sealed with liquid sealant.

The end section 21 can have a length slightly greater than the width of the second bead 16 in the sealing profile 10, so that one end of the end section 21 slightly overlaps the rib 15 in the sealing profile 10, for example by up to 4 mm, preferably between 1 mm and 3 mm. Since both sealing profiles 10 and 10' are made of an elastic material, a seal is essentially created in the area of the overlap. The first rib 13 in the sealing profile 10 ensures in any case that no moisture can enter the structure via the post 2.

Figure 4 shows the back of the intersection of Figure 3 and it can be seen that in the area of the end section the sealing profile 10' is cut in the area of the first bead 14, the rib 13 and in the area of the sealing rib 17. For drainage from the sealing profile 10' in the crossbar 3 into a groove in the sealing profile in the mullion 2, the rib 15 forms a groove bottom of a drainage groove which extends to the rib 15 in the sealing profile 10. In the assembled position, the ribs 15 of the sealing profiles 10 and 10' are arranged essentially in the same plane and only in the area of the overlap is the rib 15 slightly deformed to compensate for the overlap. The overlap can also be sealed by means of the elastic material.

Figure 5 shows a sectional view through a mullion in which a sealing profile 10 with a recess 20 is installed. In the area of the recess 20, the second sealing strip 16 is cut away and the hatching indicates that in the area of the recess the first sealing strip 14, the first rib 13 and the second rib 15 are formed continuously. In the area of the recess 20, the sealing rib 17 between the two sealing strips 14 and 16 is also missing.

Figure 6 shows a sectional view through the sealing profile 10' on a cross member 3 in the area of the end section 21. The first rib 13 and the first sealing strip 14 have been removed from the sealing profile 10' in the area of the end section. In addition, the sealing rib 17, which is integrated into the second sealing strip 16, is also missing. By removing the sealing rib 17, the cross member sealing piece 22 with the side ribs 24 can be inserted into the space between the first sealing strip 14 on the sealing profile 10 and the second sealing strip 16 on the sealing profile 10'. The block 23 of the cross member sealing piece is arranged in the area of the threaded groove 4 and can, if necessary, also be shaped according to the contour of the threaded groove 4, i.e. with a central groove.

In the exemplary embodiment shown, an intersection of a post-and-crossbar structure 1 has been described in detail. Such an intersection can be provided at all connections between posts 2 and crossbars 3 or between two crossbars 3 arranged at an angle, the protruding end section 21 being both on a sealing profile 10', which is mounted on a crossbar 3, and on a sealing profile 10, which is mounted on a post 2. The term crossbar sealing part 22 therefore also includes an arrangement of this component on the extension of a post 2 instead of on a crossbar 3.

In the exemplary embodiment shown, the ribs 13 and 15 are arranged in parallel. It is of course also possible to align the ribs 13 and 15 at an angle to one another. Furthermore, the rib 13 can also be formed on the rib 15 instead of on the leg 12. The ribs 13 and 15 then form a "Y", although the length of the ribs 13 and 15 can also be different. The rib 13 can then be designed as a joint, arch or hook.

Figure 7 shows a view of a modified sealing profile 10" which can be mounted on a post or a crossbar. The sealing profile 10" has a central section 11, a first sealing strip 14, a second sealing strip 17 as in the previous embodiment. However, the first rib 13' is not designed parallel over the entire width of the second rib 15, but has an angular cross section. The first rib 13' thus connects the first sealing strip 14 to the rib 15 in a central area and not to the leg 12.

In order to mount the sealing profile 10" at an intersection of a mullion 2, the draught excluder 16 can be removed using a tool 30 to form a recess 20, so that the rib 15 remains mounted on the mullion. The sealing profile 10" can also be mounted on a transom 3, with the draught excluder 14 with the angle rib 13 and the sealing rib 17 being removed to obtain an end section 21, optionally also the fastening element 9, so that a transom sealing piece 22 can be placed on the end section 21.

Figure 8 shows a sealing profile 10'', which has a U-shaped central section 11 with two parallel legs 12, similar to that shown in Figure 2. Two ribs 13 and 15 protrude from each leg 12, on each of which a weatherstrip 14 or 16 is formed. The two ribs 13 and 15 are connected to each other via a connecting rib 18, the connecting rib 18 being optionally integrated with both ribs 13 and 15 or integrated with only one of the ribs 13 or 15 and resting loosely on the other. A hollow chamber 19 is formed between the connecting rib 18 and the rib 13.

In this exemplary embodiment, the first sealing strip 14 and the second sealing strip 16 are loosely pressed against each other. A profile with two strip-shaped projections 31 is formed on the side facing the first sealing strip 14 on the second sealing strip 16, each of which engages in a receptacle 32 of the first sealing strip 14. This profiling prevents the sealing strips 14 and 16 from moving in a direction perpendicular/lateral to the longitudinal direction. The profiles can be designed as strip-shaped projections 31 and receptacles 32, but also as a tongue-and-groove connection or as grooves, ribs, recesses or other geometries. Furthermore, the number of interlocking profiles can vary. The two sealing strips 14 and 16 are only loosely pressed against each other and can therefore be easily separated from one another, for example to form a notch. A recess 33 is formed in the first weatherstrip 14, into which a hook 6 can be inserted into a post 2 or crossbar 3 to fix the weatherstrip 14.
