.Truss-ball joint for truss structure.

摘要

The present invention relates to a truss ball joint for a truss structure, and more specifically, easily combines another truss ball horizontally or vertically with a truss ball for making a truss structure used for installing various exhibition halls, concert halls, advertising towers, or the like. The present invention relates to a truss ball joint for truss structure that can be detached and improves the bonding force, thereby making the truss structure more robust and safe.;Truss ball joint for truss structure according to the present invention is a truss for truss structure truss for truss structure truss bar or truss ball truss ball is formed in the center of the coupling surface is coupled with a plurality of insertion holes are formed in the edge of the coupling surface In a truss ball joint for truss structure that connects the ball and the truss ball for truss structure horizontally or vertically, the truss ball joint for truss structure is the upper and lower surfaces coupled to the coupling surface of the truss ball for truss structure The bolt hole is formed in the center of the bolt hole is fastened in accordance with the screw hole is formed and the side portion is formed through a plurality of insertion projections are formed in accordance with the insertion hole in the outer surface of the upper surface and the outer surface of the lower surface Connecting the insertion protrusions adjacent to the outside of the plurality of insertion protrusions; It characterized in that the support strip is integrally formed.;According to the truss bar joint for truss structure according to the present invention, by inserting a plurality of insertion projections into a plurality of insertion holes and fastening the bolt to the central bolt hole, it is possible to construct a truss structure having a firm coupling structure and also easily The truss structure can be combined or disassembled, and the plurality of insertion protrusions are integrally supported by the support belt, thereby making it possible to construct a more robust and safe truss structure.
