The invention discloses a support type ball joint for a giant space truss. The support type ball joint is characterized by comprising a hollow ball joint and and a support, wherein the support is fixed with the hollow ball joint through a ball at the lower end of the hollow ball joint. The support comprises a box body, a base and an upper cover plate fixed at the upper end of the base. A boss used for limiting and fixing the base is arranged on the inner wall of the box body. A cover plate at the upper end of the box body fixes a fixed adjusting portion fixed with the base in the box body. The base and the upper cover plate form a holding space for fixing the ball, and the ball can rotate in the holding space by any angles. By the aid of the integrated structure of the hollow ball joint and the support, the support can translate and rotate to consume temperature stress of a roof truss structure in a normal use state. Meanwhile, the integrated structure can resist earthquake and strong wind, guarantee safety of the roof truss structure, the height and the size of the support can be effectively reduced, eccentricity of the support is reduced, manufacturing cost is low and construction and mounting speed is increased.
Description
technical field [0001] The invention relates to a support construction node technology for a space long-span roof truss or a complex space structure, in particular to a support type ball joint for a giant space truss. Background technique [0002] At present, in the actual space structure, the support is an essential and important component. Due to the diversification of the form and force requirements of the space structure, the structural form and technical requirements of the support also change accordingly. In the space roof truss system with irregular curved surface, the actual engineering structure is a multi-tube, thin column, long-span and long cantilever complex space combination structure. pick, connected with the outer protective structure, so the roof truss support is in a very unfavorable stress state, mainly manifested in: [0003] 1. The area of the roof truss is large, and the vertical reaction force of the support is huge. For example, the area of the ...
