FIELD: construction.SUBSTANCE: corrugated deck sheets are laid onto bearing structures, for instance, trusses, according to cantilevered scheme. Brackets from sheet steel are installed before overlapping of ends of cantilevered sections of corrugated sheets onto walls or shelves of lower ends of sheets at close range. After installation of brackets as overlapping, they lay an upper end of a corrugated sheet, and the protruding part of the bracket is bent relative to ends of walls or shelves of upper ends of overlapped sheets to contact with its surface. Final fixation is done by installation of fastening elements in the form of self-drilling bolts or combined rivets.EFFECT: increased strength of connection of cantilevered sections of corrugated deck sheets under action of forces to direct deck sheets.5 dwg |
