Abstract
The utility model discloses a steel pipe truss hinge joint device, which mainly comprises a steel pipe truss, a rubber cushion block, an embedded part and a concrete fixing device, wherein the embedded part comprises a horizontal steel plate and a steel bar which is vertically fixed to the horizontal steel plate by welding; the steel bar is embedded into the concrete fixing device; a support and a support transition plate which are formed integrally with the steel pipe truss are arranged at the lower end of the steel pipe truss; the rubber cushion block is arranged between the support and the support transition plate through an anchor bolt; the support transition plate is fixed to the upper end of the horizontal steel plate by welding. The steel pipe truss hinge joint device has the advantages that a right-angle hook is arranged at the bottom end of the steel bar, so that the friction force between the embedded part and the concrete fixing device is improved greatly; the support arranged at the lower end of the steel pipe truss is welded with the steel pipe truss, and the stress gravity of each steel pipe of the truss is prevented from being converged at one point, so that the eccentric force on joints is avoided, the carrying force and rigidity of hinge joints are effectively improved, and the requirements on the hinge joints of the steel pipe truss in the building field can be met.
