Abstract
The invention discloses a steel pipe truss hinging node device, which is mainly formed by a steep pipe truss, a rubber heel block, an embedded part and a concrete fixing device; the embedded part comprises a horizontal steel plate and steel bars vertically fixedly welded with the horizontal steel plate; the steel bars are arranged in the concrete fixing device; a support and a support transition plate which are integrally molded with the steel pipe truss are arranged at the lower end of the steel pipe truss; the rubber heel block is arranged between the support and the support transition plate by an anchor bolt; the support transition plate is fixed at the upper end of the horizontal steel plate in a welding mode. The steel truss hinging node device has the advantages that right angle hooks are arranged at the lower ends of the steel bars, thus greatly enhancing the friction between the embedded part and the concrete fixing device; the support arranged at the lower end of the steep pipe truss is welded with the steel pipe truss, so stressed centers of all steep pipes of the truss cannot be converged at one point, the existence of eccentric force at a node is avoided, the bearing force and rigidity of the hinging node are effectively improved, and the demands of the building field on the steel pipe truss hinging node are met.
Description
Technical field
The present invention relates to a kind of construction work steel pipe truss device, specifically, relate to a kind of steel pipe truss hinged joint device.
Background technology
Steel pipe truss is called for short steel truss, refer to the truss that main employing steel are manufactured, be mainly used in industrial premises, warehouse, sports palace, exhibition hall, meeting-place, terminal, station, in the industrial construction such as office building and civilian construction, and steel pipe truss conventionally in above-mentioned building as the main member of load-carrying members, conventional is three, four sides or multiaspect plane frame, but the stressed center of gravity of the each steel pipe of common steel pipe truss can not be intersected in a bit, and conventionally there is eccentric force at Nodes, require strict region in heavy construction and earthquake resistance and prevention, the bearing capacity and stiffness of hinged joint can not meet the demands.
