MOUNTING SYSTEM, ESPECIALLY FOR USE IN FIRE WALLS

FOR GLASS PLATES - INFATTNINGSSYSTEM, I SYNNERHET FÖR GLASSSKIVOR

I BRANDVÄGGAR

The present invention relates to a fastening system, in particular for glass panes for use in fire walls, to prevent the flow of smoke / air and the formation of thermal bridges in the event of fire, comprising one or more against the end faces and at opposite edges of the glass sheets.

Until recently, internal fire insulation walls have been made e.g. plaster, concrete, steel, etc. Recently, types of glass have been developed that meet the insulation / integrity requirements for fire insulation. Fastening systems for glass are known in which some of the beams form fastening devices which, together with, for example, rubber seals, hold the glass in place, as disclosed in GB 1479403 and DE 3048152. However, these are not particularly suitable for fastening systems in fire insulation walls. In the event of a fire, the seals will burn and create air * holes and a small chance of the walls collapsing.

NO 143814, GB 1470996 and GB 2046824 and 2088940 disclose fastening systems in which the edges of the glass pane are surrounded by a fireproof seal and in which fastening is by screws.

The fastening system according to the present invention provides a construction which, in the event of a fire, retains its properties, i.e. holds the glass firmly in place and prevents the formation of air holes in the partition wall.

The fastening system according to the invention is characterized in that the soft insulation is fastened in place against the glass sheets by means of a screw connection between a small and a hard, fireproof insulation sheet.

The fastening system according to the invention substantially prevents the passage of heat through the wall and the collapse of the wall in a fire. Despite the burning of the rubber seals, the fireproof insulation material ensures that no air or smoke can pass from one side of the wall to the other.

In the following, the invention will be explained in more detail with the aid of the accompanying drawing, in which the figure shows a cross-section of a fastening system according to the invention. The glass sheets 4 are attached to steel beams 1 which are substantially "hat" shaped. Steel beams form the load-bearing frame of the partition and are often arranged as a "lattice structure". When mounted on a ceiling, wall or floor, one glass is replaced with a steel profile that is attached to the building. Steel beams can be formed, for example, from two steel profiles which are welded together or cold-rolled in part.

The fireproof insulation board 2 is fastened to the steel profile 1 with screw connections, for example. The insulation board 2 and the steel profile 1 ensure sufficient fastening to the glass sheets 4 so that the insulation board 2 comes from its edge areas and the steel profile 1! flange portion against the glass sheets and such that direct contact of the glass sheets with the steel profile 1 and the hard insulation 2 is prevented by a flexible fireproof insulation 5, which insulation 5 is compressed between the insulation 2 and the glass sheet 4 and the glass sheet 4 and the steel profile.

After the fastening system has been installed, it is covered, for example, with an aluminum profile 3, which is pressed outside the hard insulation board 2.

In order to prevent water and the corresponding entry into the beams, the gaps between the cover strip 3 and the glass plate 4 and the steel profile 1 and the glass plate 4 can be sealed, for example, with rubber strips 6, which are carefully pressed in.
