LARGE-SPAN SPATIAL SYSTEM OF BUILDING COVER Russian patent published in 2013 - IPC E04B7/08 

FIELD: construction.

SUBSTANCE: large-span spatial system of a building cover includes an arched cover fixed by a system of stiffening elements, made in the form of two-slope glued veneer boards, joined and fixed on two-slope glued board beams, forming the upper belt of wood and metal trusses. Trusses are made with a metal brace connected to the upper belt with the help of wood struts and are supported onto columns, or elements of the building and are defixtured in longitudinal direction by tie trusses. The two-slope board is made of "П"-shaped cross section with two-slope longitudinal glued board ribs, connected by transverse glued board ribs and upper lining. Two-slope longitudinal ribs in ends of the board are equipped with L-shaped slots at the side of the board base and are strengthened by inbuilt inclined rods. Boards are laid with L-shaped slots onto beams of the upper belt of trusses and are joined by ends by means of pads installed on top.

EFFECT: higher stiffness and strength of a structure.
