Prefabricated load-bearing and insulating element for building construction

摘要

The webs of the load-bearing ribs (2) of the prefabricated load-bearing and insulating element (1) are produced, from derived-timber-product panels, as framework diagonals (6) which are cut in a continuous form and also permit an upper chord which is inclined with respect to the lower chord. If required, transition to the solid-wall web (18), consisting of derived timber product, is possible at any point. The suction anchorage of the roofing skin, in the case of trapezoidal metal sheet design, takes place without screw-connection via punched and shaped sheet-steel parts (13, 14) which are hooked behind nails (16) projecting from the battens (4). The battens (4) are connected on site, by nailing, to the load-bearing ribs (2) corresponding to the position of the shaped steel parts (13, 14). <IMAGE>
