DISMOUNTABLE ASSEMBLED H-BEAM WITH HOLLOW SHELVES AND DOUBLE WALL Russian patent published in 1995 - IPC

FIELD: civil engineering. SUBSTANCE: dismountable assembled H-beam with hollow shelves and double wall consists of two similar sections with a wall displaced towards shelves. The walls are connected to one another with the shelves using lock-type members in the form of folding on one shelf end of a section. Increased local stability of beam shelves and beam carrying capacity with decreased metal consumption is provided at the expense of curvature of faces of section shelves. Corrugates on internal face of opposite shelf in each section are made, and one section folding is made so to fix another section in holes of corrugates. Internal or external faces of section shelves with folding lock-type member are bent so to have at least one contact to internal or external faces of section shelf. EFFECT: high technological effectiveness. 4 cl, 6 dwg
