EP0314052B1 - Sealing system for glazed roofs and glazed walls - Google Patents

Description

For the contracting states BE, LU and NL, the invention is based on an elastic intermediate profile which is to be inserted between rafters and purlins of a glass roof or post and transom of a glass wall and glass panes held on the outside by the rafters and purlins or post and transom which are supported with their edges on a contact surface of the intermediate profile.

Rafters are to be understood as the bars of an inclined glass roof that run obliquely from top to bottom, and purlins that run horizontally across them. Posts are the corresponding vertical or steeply inclined, and transoms are the corresponding horizontal load-bearing elements of a glass wall.

Glass roofs and glass walls are sealed at the edges of their individual glass panes on the outside, usually between the glass and an aluminum profile located between the glass panes. The water penetrates through leaks. Aluminum profiles serving as load-bearing rafters and purlins or posts and transoms have been constructed in such a way that they catch and drain this water. However, it is usually not possible to transfer the water at the joints between purlins and rafters and between mullions and transoms, but above all the rafters are transferred to posts. Water is running out somewhere.

The invention has for its object to provide a complete line system for water penetrated by the seal.

According to the invention, this purpose is achieved with an intermediate profile of the type mentioned at the outset, which is subdivided under the contact surface into a lower and an upper position and in which an elevation runs parallel to the contact surface, to which a variant of the intermediate profile for the rafters or The post connects the lower layer and, in a variant of the intermediate profile for the purlins and transoms, connects the upper layer.

The intermediate profile is laid continuously on the rafters and posts and laid on the purlins and transoms in such a way that at the abutment the top layer of the continuous intermediate profile is cut out across the width of the adjoining intermediate profile and the lower layer of the adjoining intermediate profile on one Length is cut off, which is preferably equal to the width of the cut out top layer; the remaining upper layer is placed in the cut-out with lateral contact of the lower layers of the two intermediate profiles. How the water is led here is explained in detail below.

The intermediate profile is preferably divided by an incision in the lower and the upper layer, and the two layers are connected to one another on the outer edge of the sealing profile. With the incision, it is easiest to cut out or cut off the intermediate profiles at the joints in the manner indicated above; the piece to be removed is largely separated by the incision. Instead of the incision, a subdivision would also be conceivable, which allows tearing or facilitating cutting, for example with a perforation or the like.

The cross section of the intermediate profile will be symmetrical, the elevation in the middle and two legs with two contact surfaces and the two layers on each side.

As far as it is laid on the edge of the roof, one leg that is not required can be cut off. However, it is also possible to provide a separate, one-sided intermediate profile or to design the roof edge in a completely different way.

For the contracting states CH, FR and LI the invention belongs to the unpublished state of the art in this respect due to EU-A 0 268 829. The same applies to DE through DE-A-36 39 848.

The following further developments of the invention are new for all designated contracting states.

According to an advantageous embodiment of the invention, the elevation is designed as a box profile onto which a rigid profile strip can be plugged for connection to a further profile placed over the glass panes.

In addition to the connection of the (lower) intermediate profile with the (upper) other profile, which serves the molded box profile, the box profile has the following advantage: screws driven into the rafters, purlins, mullions or transoms from above have a double seal in the box profile , on the intermediate profile, the first already at a higher level, on which penetrated water can run off more cheaply.

As the further profile, the same as the intermediate profile under the glass panes can be laid continuously over the rafters or posts, and a flatter profile can be laid against the purlins or bars in such a way that the continuous profile is also cut out and the flatter Profile is placed with its end in the cutout.

In the variant of the intermediate profile for the rafters or mullions, according to a further advantageous embodiment, the incision rises towards the outer edge, in a different way a kind of groove is formed further inwards on the lower layer det, which prevents water from escaping from the edge at the joint where the upper layer, which is otherwise closed at the edge, is missing.

So that there is a channel of sufficient cross-section throughout, in the variant for the rafters and mullions, the upper layer preferably has a free distance from the elevation, as already according to the unpublished prior art mentioned.

Finally, to transfer the water from the rafters to the posts, it is simply proposed to continue the intermediate profile from the rafters continuously downwards over the lower edge of the roof and onto the posts.

The drawing shows an embodiment of the invention.

It shows a joint between a rafter and a purlin in a perspective view with different cuts.

A rafter 1 runs slightly obliquely according to the inclination of the roof, a purlin 2 at right angles to it in the horizontal.

An intermediate profile 3 made of rubber or another soft-elastic material is laid continuously on the rafters 1 in a variant 3a and is laid on the purlin 2 in an abutting manner in a variant 3b.

In both variants, the intermediate profile has a continuous lower layer 4 and an upper layer 5 connected to it at the two edges and otherwise separated from it by an incision 10, on which two ribbed contact surfaces 6 are formed following the two edges. The lower layer 4 and the upper layer 5 are together of the same thickness in both variants 3a and 3b. All contact surfaces 6 are of the same width. In both variants, a box profile 7 with ribbed side surfaces rises in the middle, namely in variant 3a on the lower layer 4 and in variant 3b on the upper layer 5, which runs through the entire profile width here.

In variant 3a, the upper layer 5 is interrupted in the middle. It ends on both sides of the box section 7 at a distance from it, so that a groove 8 remains. From the bottom of the channel 8, the incision 10 rises slightly outwards on a cross-sectional section 9, the thickness of the upper layer 5 decreasing to the same extent as the thickness of the lower layer 4 increases. An end section 11 is again the same. Also in the lower layer 4 alone, a flat channel is formed, which is delimited towards the edge by the cross-sectional section 9 and which is delimited inwards by the box section 7.

At the joint, the top layer 5 is cut out from variant 3a and the bottom layer 4 is cut off from variant 3b; the end 12 of the upper layer projecting in this way, which is as long as the contact surface 6, is placed in the cutout. It lies on the lower layer of the cut-out intermediate profile on the cut surface and on the end section 11 of the incision adjoining it in the same plane, where the lower layer of variant 3b is as thick as that of variant 3a, and then projects freely over the cross-sectional section 9, which slopes down from here. The cantilevered end can be seen at 13.

The cutting out and cutting off is facilitated by a narrow groove 14 running on the outer edge of the profile as a gauge for the cut that extends the incision 10 outwards.

A glass pane of double glazing is shown at 15 of the four glass panes colliding with one corner each in the depicted section. The glass panes 15 each lie with their edges on the contact surfaces 6, on the inner edges of which approximately with them.

The gaps between the glass panes 15 are covered on the upper side by profiles 18 and 19 which are arranged in mirror image to the intermediate profiles 3 and are connected to them by rigid profile strips 16 and 17.

Profile 18 is the same as intermediate profile 3, preferably in variant 3a. The profile bar 16 is plugged onto the box profile 7 of the intermediate profile 3, the box profile 7 of the profile 18 is inserted into the profile bar 16.

The profile 19 is only one layer and as thick as the upper layer 5 of the intermediate profile 3 at the end section 11. It also has a box profile, designated 20 in the middle, by means of which it is connected to the intermediate profile 3 via the profile strip 17 .

The profile 18 is in turn laid continuously and cut out at the joint to accommodate the end of the profile 19 in the cutout.

Along the edges of the profiles 18 and 19 is sealed between them and the glass panes 15 with a sealant. In the event of leaks, the water runs down under the profile and outside at the edge of the glass pane 15. There is a particular risk in this respect on the higher edge and leg of the profile 19, which is opposed to the direction of flow of the water, and then below it in the intermediate profile variant 3b.

In this, the water can now only continue on the path indicated by the serpentine lines, namely in the space between the contact surface 6 and the box section 7 or, more precisely, in the angle between the slightly inclined base of this space and the wall of the box section. It then runs from him at the end of the profile to the one below that end located groove 8 of the profile variant 3a and in this down further, as shown with the further course of the serpentine lines. Water running down over the edge of the glass pane 15 located below the profile 18 immediately enters the channel 18. If, for example due to wind pressure, water penetrating through a leak crawls under the lower leg of the profile 19 and comes over the upper edge of the glass plate 15, will it is only a question of comparatively small quantities, which are also carried on this side of the box section 7, not along this, but also along the somewhat raised, ribbed contact surface 6 along to the end of the intermediate section and from there into the channel 8. In the gutters 8, the water flows past all joints to the lower edge of the roof and, when the intermediate profile is laid over the edge of the roof, downwards in this way.
