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).

Double-shell wall system

The invention relates to a double shell Wall system of the type specified in the preamble of claim 1.

There are two known wall systems that have their advantages and disadvantages. In the case of the first, of the one in question If it is assumed, special horizontal bars, mostly U-profiles, are attached to the outside of the supports. The inner profile sheets are attached to these bars, which are usually 2.0 to 4.5 m apart (e.g. trapezoidal sheets) attached with screws, which at the same time act as one of the (inner) legs of spacers hold from Z-profiles, which penetrate the insulation layer and on their outer legs the outer profile sheets (also e.g. trapezoidal sheets). The outer profile sheets transmit the wind forces via the Z-profiles into the wall bars, which in turn transfer the forces into the supports. This wall construction is quite complex and leads to an excessive thickness of the wall (column + inner profile sheet + Insulation layer (including Z-profile) + external professional 1 bl ech). Since the Z-profiles have the same distance as the transoms, the K-value (thermal resistance) not bad.

In a second known embodiment, the so-called "cassette construction", special bolts are omitted, because the wind forces are transmitted directly to the supports via cassette bars. However, because of static reasons, the cassettes can not have a large height dimension and thus the

Cassette bars usually only have a distance of between 400-600 mm from one another, a significant reduction occurs of the K-value for this wall system.

The invention is based on the object of creating a wall system which combines the advantages of the two known systems described with relatively simple, cost-saving structural means and which enables simpler assembly.

According to the invention, this object is achieved by the characterizing features of claim 1. Expedient developments of the invention are the subject of the subclaims.

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

Fig. 1 is a vertical section through a portion of the wall system and

FIG. 2 shows an enlarged illustration of the cross-sectional profile of a spacer compared to FIG. 1.

The wall system shown has inner profiled sheets 1 and outer profiled sheets 2, between which there is an insulating layer 3 is located. The inner profile sheets 1 are attached to flanges 4 of spacers 5, while the outer Profile sheets 2 on narrower flanges 6 of the spacers 5 attached, e.g. 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 with safe transmission of wind forces no reduction in the K value occurs.

As shown in particular in FIG. 2, each spacer is 5 bent from sheet metal (e.g. from galvanized thin sheet 2 mm), the flanges 4, 6 with double! Layered sheet metal folds are formed. The spacers therefore 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 work required during assembly can be carried out from the outside will.
