METAL MULTILAYER WALL AND METHOD OF ITS INSTALLATION Russian patent published in 1997 - IPC

FIELD: construction. SUBSTANCE: metal multilayer wall includes cross-bars with longitudinal supporting members, interior and exterior profiled sheets and warmth-keeping plate located between them, and supporting cantilevers with furring. Supporting cantilevers are installed on flange of longitudinal supporting members from one end of each interior profiled sheet with the help of anchor washers interconnected by fastener passed through hole in this sheet. Anchor washers consists of plates and installed for resting on one of them on flange of longitudinal member and pressed with the other plate. Exterior profiled sheets are secured to furring. Warmth-keeping plates are installed on furring and intermediate Z-shaped members whose one flange is fastened to interior profiles sheet, and the other is made of parts bent through 90 deg with folding of its horizontal part upward. The method of installation of metal multilayer wall includes installation of cross-bars with longitudinal supporting members installed on them, sheet-by-sheet installation of interior profiled sheets with the help of auxiliary clamps on longitudinal supporting members and their fastening to flanges, installation and fastening of supporting cantilevers with furring, laying of warmth-keeping plates on furring and intermediate Z-shaped members, and sheet-by-sheet successive installation of exterior profiled sheets. After installation of each interior profiled sheet on longitudinal supporting member, removable jig is arranged near this sheet. Removable jig is in form of L-shaped clamp with hole whose location is fixed relative to the flange, which is used to bore hole from scaffolding in interior profiled sheet for member fastening. The last to be connected is supporting cantilever and anchor washer, with anchor washer pressed to flange of longitudinal member. When laying the warmth-keeping plates onto intermediate Z-shaped members, which are secured to interior profiled sheet, horizontal parts of free flange are bent upward. EFFECT: higher efficiency. 5 cl, 13 dwg
