Cross buckling restrained brace of cutting hot rolling angle steel combination

Cross buckling restrained brace of cutting hot rolling angle steel combination, belong to civil engineering structure energy dissipation shock attenuation technical field, two hot rolling angle steelopposite vertexes of cutting molding make up the core supporting member that becomes to be the star section, the active section spot welding of core supporting member, the inoperative section adopts degree of depth welding technique to be linked to be whole, put into the iron stand behind the position that diagonal embedding square steel tube set for, one side of the lower end plate of messenger'swelding down, and with sealed square steel tube of silica gel and lower end plate gap, in order to avoid leak the thick liquid, fill light aggregate concrete and reach after the requirement intensity, adopt the spot welding mode to install the end plate. The utility model discloses a hot rolling angle steel avoids traditional cross buckling restrained brace to adopt the steel sheet to lead to temperature stress, residual
