PREFABRICATED BUILDING OF LIGHT METAL STRUCTURES Russian patent published in 2011 - IPC E04B1/02 

FIELD: construction.

SUBSTANCE: prefabricated building comprises transverse frames of the carcass from pillars, which are hingedly connected to the foundation, and crossbars made of welded double tees of alternating cross section, combined during assembly by means of flange joints, stands of framed structures and multilayer barrier wall and roof structures of the roof. The surface of the barrier structures that are inverted inside the building is formed by walls of cassettes fixed to the elements of the carcass and the stands of the framed structure and made of the metal sheet with L-shaped ribs bent at longer sides to form a cavity filled by heat insulation. The external surfaces of wall and roof structures are fixed to the ribs of the cassettes via an additional layer of heat insulation. The building is equipped with channel-like stiffening elements installed inside cassettes and connected with their walls to the walls of L-shaped stiffening ribs. In the roof structure the stiffening elements rest against the frame crossbars, and in the wall structure they are installed in cassettes adjacent to the framing of window and door openings and in the cassettes that form the pedimental part of the wall.

EFFECT: increasing bearing capacity of the building.
