Description

[Detailed Description of the Invention] This invention relates to a surface structure that constitutes the roof surface, outer wall surface, etc. of a building.

Generally, as a planar structure in this type of building, as shown in FIG. When laying a plurality of inner layer members 2, a well-known method is to interpose connecting members 3 each having an inverted T-shape in cross section between the abutting ends of each inner layer member 2. .

However, in the conventional case with such a configuration, the connection member 3 having an inverted T shape has a second
As shown in Figures 3 and 3, thin steel plates are folded and folded into double layers, which not only requires a large amount of steel plate material, but also makes the forming process itself relatively troublesome. Since the cross-sectional shape is simply an inverted T-shape, it can only support and regulate the position of each inner layer member 2, but is hardly useful for fixing it. The appearance of the connecting portion between each inner layer member 2 and the connecting member 3 is poor, and after the inner layer members 2 are laid together with the connecting member 3 interposed in this way, each inner layer member Although not shown here, it is absolutely impossible to create a configuration in which another outer layer member is attached through the heat insulating space to obtain the desired surface structure. It was unbelievable.

This invention is an attempt to improve such conventional problems, and its purpose is to improve the connecting member and the mounting member added to this connecting member, so that each supporting member can be A surface of this type of building that interconnects the inner layer members laid on top and also allows outer layer members to be attached to each inner layer member via a space for heat insulation etc. The purpose is to provide a structure.
