Sealing strips for glass roofs and glass facades

The invention relates to a sealing strip for glass roofs and glass facades according to the preamble of the main claim.

Sealing strips are known that are applied to a metal structure made of square tubes and serve as a sealing and support element for glass elements or glass panes. Vertical and sloped glazing is carried out using such structures. With conventional sealing strips, these are designed as separate horizontal and vertical strips, whereby in the connection area between horizontal and vertical sealing strips, it has not yet been possible to achieve a secure seal against the ingress of water without additional measures. An additional external seal is therefore often applied in the area of the butt joints using silicone compound, which, however, usually has a relatively short lifespan due to strong temperature fluctuations and other weather influences. In addition, the silicone compound can only be processed in dry weather, which often causes delays in installation.

The invention is based on the object of creating sealing strips for glass roofs and glass facades or the like, which ensure a permanent, secure seal against water without additional auxiliary seals.

The solution to this problem is achieved by the features specified in the main claim. The overlapping design in the connection area between vertical and horizontal sealing strips ensures that the joints on the sealing lips run horizontally and are arranged in the area of the vertical sealing strips. Even if water were to penetrate the outer sealing strips in the area of these joints, it could flow down the vertical inner sealing strips and be easily drained away at the bottom of the glass facade. Additional silicone sealing measures are no longer required here and a permanently secure seal is achieved.

It is particularly advantageous to provide additional sealing lips running along the front sides of the horizontal sealing strips that extend laterally over the longitudinal edges of the sealing strips. The end of the horizontal sealing strips thus has a roughly T-shaped outer contour. The sealing lips arranged on the front side engage in a recess on the vertically running sealing strips and thus become part of the sealing lips arranged on the longitudinal edges of the vertically running outer sealing strips. The front sealing strips can be subsequently vulcanized, with a rounded transition between the front sealing lips and the sealing lips running along the longitudinal edges being provided for good sealing against rainwater or the like.

The inner sealing strips form a common gap, which is limited to the outside by the sealing lips running along the longitudinal edges of the vertical and horizontal sealing strips. This common gap has the advantage that condensation or, in an emergency,

if

In this case, rainwater that penetrates inside can flow from the horizontal sealing strips to the vertical sealing strips and from there to the outside.

Several adjacent sealing lips can be combined into sealing strips, which are connected to the bottom of the sealing strip via a special web. This narrow web connection makes it possible to easily separate the sealing lips combined into sealing strips from the sealing strip in the area of the web, which allows the recesses to be created into which the end faces of the horizontally arranged sealing strips overlap.

Sealing grooves or sealing lips can also be provided on the side of the sealing strips facing away from the sealing lips, which can rest on the top of the bottom of the sealing strip in the case of the outer sealing strips. Corresponding sealing grooves that interact with these sealing grooves can also be provided on the surfaces of the sealing strips facing the sealing strips. Sealing lips running on the front side of the horizontal sealing strips can engage in these sealing grooves, thereby achieving a particularly good connection between the horizontal and vertical sealing strips.

In the overlapping area, where the horizontal and vertical sealing strips interlock, a positive connection can be provided between the sealing strips, which can also safely withstand higher tensile forces. Interlocking sealing grooves are preferably used for this purpose.

Advantageous further developments of the invention are characterized in the remaining subclaims.

The invention is explained in more detail below with reference to the drawing
explained. They show:

Figure 1 shows a section in the area of the sealing strips 1, 2, between which insulating glass
Glass elements 3 are arranged. The inner sealing strip 2 rests on a steel tube 4, while the outer sealing strip 1 is held by a metal rail 5 and pressed against the outer glass surface 6. The sealing strips 1, 2 are made of rubber, the outer sealing strip 1 having molded-on sealing lips 7 which are intended to prevent the ingress of rain water or the like. In order to ensure reliable sealing in the area of the crossing points, the sealing strips 1, 2 are designed there in accordance with Figures 2a b. in 3c. |

strip 11 in the area of a crossing point. The horizontal sealing strip is inserted in the direction of arrow a during assembly in an overlapping manner into a recess 8. The recess 8 is formed by the sealing lips 7, which form a sealing strip 9, being cut out or separated. On the horizontal sealing strip 11 there is a sealing strip 10 on the front side, which fits exactly into the recess 8 and thus represents the continuation of the sealing strip 9 in this area.

Grooves 12 (Figure 2c) are formed on the underside of the sealing strip 10, which engage in corresponding grooves 13 on the sealing strip 1, creating a connection between the vertical and horizontal sealing strip that can withstand high tensile stress. The sealing grooves 13 run along the longitudinal edges 14 of the vertical sealing strip 1 over the entire length below the sealing strips 9.

The sealing lips 7 running along the front side, which form the sealing band 10 of the sealing strip 11, are connected to the remaining sealing strip at the connecting line 15 by vulcanization.

When designing the sealing lips 7, it is particularly important that a rounded transition is formed in the corner area 16 between the horizontally running and the front-side sealing lips 7. This rounded transition ensures reliable sealing against rainwater or the like.

Figure 2b shows the cross-section of the vertically running sealing strip Ii, whose sealing strips 9 are only connected to the bottom 18 of the sealing strip 1 via narrow webs 17, which are formed on the longitudinal edge. The webs

17 allow a desired recess 8 to be made very easily at any point on the sealing strip 1. To do this, the narrow web only needs to be cut off with a knife.

In Figures 3a to 3c, a vertically running sealing strip 2 and a horizontally running sealing strip 22, both of which serve as inner seals, are shown in the area of an intersection point. Both sealing strips 2, 22 have sealing lips 19 which form sealing strips 20, 21. A recess 23 is provided on the sealing strip 2, into which the sealing strip 22 is inserted with its front side 24 overlapping in the direction of arrow b. For this purpose, a shoulder 25 is formed on the underside of the sealing strip 22 by cutting off support strips 26 running on the underside along the dividing lines 27. A corresponding shoulder 28 is also formed on the front side of the outer sealing strip 11 (Figure 2c).

In the case of the inner seal, which consists of the sealing strips 2 and 22, the intermediate space 29, which is delimited by the sealing strips 20, 21, is a common space in which any water that may penetrate can flow downwards in the direction of the arrow w.

The sealing strips 20 are, like the sealing strips 9, only connected to the base 31 of the sealing strip 2 via narrow webs 30, so that recesses 23 can also be easily made at any point. The support strips 26 are also only connected to the remaining sealing strip 22 via narrow webs 32.

Sealing grooves 33 can also be formed on the sealing strip 2, which can interact with corresponding grooves in the area of the shoulder 25 so that the sealing

strips 2j 22 form a positive connection after the entire construction has been assembled and can therefore withstand high tensile forces.
