Abstract

1. Double skin wall system with inner and outer profiled sheets, which are connected together by distance pieces and receive an insulating layer therebetween, wherein bars are provided as distance piece serving to transfer the wind forces to the supports of the wall system, which bars are fixed directly to the supports, characterized in that the bars (5) are bent double-T-shaped from sheet metal in a manner known per se, in that only the two flanges (4, 6) are formed by double thickness sheet metal folding and are connected by a single thickness web (5), and in that the inner profiled sheets (1) are fixed directly on to the inner and broader bar flanges (4) to be fixed to the supports (7), while the outer profiled sheets (2) are fixed directly on to the narrower bar flanges (6) lying outside the insulating layer (3).

Description

The invention relates to a double-walled wall system with inner and outer profile sheets, which are connected to one another via spacers and accommodate an insulation layer between them, with bars serving as spacers being provided for transmitting the wind forces to the supports of the wall system, which are attached directly to the supports are.

Such a wall system is known from US-A-4,413,458. There, however, massive cold bridges are created across the insulation layer using massive Z-profiles that serve as spacers, and the overall structure of the wall system is quite complicated and costly.

The invention has for its object to enable simple assembly of the wall system with a simple construction while avoiding strong cold bridges.

This object is achieved in that the bars are bent in a known manner double-T-shaped sheet metal, that only both flanges are formed by double-layer sheet metal folding and connected to each other via a single-layer web and that the inner profile sheets directly to the the inner and wider transom flanges to be fastened to the supports are fastened, while the outer profile sheets are directly attached to the narrower transom flanges lying outside the insulation layer.

There are bars known from US-A-1 988 147, which seem to be folded from sheet metal in a double-T shape, but the web is obviously also double-layered and therefore does not form a much weaker cold bridge than the solid Z. Profiles of US-A-4 413 458. The double-T rails of US-A-1 988 147, which are to be compared with bolts, serve with their unevenly wide outer flanges for inserting facade panels in a similar manner, such as, for. B. Sliding doors can be hung in furniture. It seems doubtful whether this construction, which is practically just a curtain wall, meets all static conditions.

The invention creates a self-supporting, self-supporting wall system that is quick and easy to install and also fulfills all requirements with regard to thermal insulation, since a good K-value (thermal resistance) is achieved through the special design of the transom.

In the drawing, an embodiment of the invention is shown. It shows

• Fig. 1 shows a vertical section through a section of the wall system and
• Fig. 2 is an enlarged view of FIG. 1 of the cross-sectional profile of a spacer.

The wall system shown has inner profile sheets 1 and outer profile sheets 2, between which there is an insulation layer 3. The inner profile sheets 1 are attached to flanges 4 of spacers 5, while the outer profile sheets 2 are attached to narrower flanges 6 of the spacers 5, e.g. B. screwed. The spacers 5 are in turn attached to supports 7 indicated by dash-dotted lines. The webs of the spacers 5 penetrate the insulation layer 3 at intervals between 2.0 and 4.5 m, so that there is no reduction in the K value when the wind forces are transmitted safely.

As shown in FIG. 2 in particular, each spacer 5 is bent from sheet metal (for example from galvanized thin sheet 2 mm), the flanges 4, 6 being formed by double-layer sheet metal folds. The spacers thus have a relatively low weight compared to the known bars, whose function they take over at the same time.

As can be seen from the drawings, all of the work required for assembly can be carried out from the outside.
