[0002] Special-shaped steel structure is also called space-arbitrary steel structure. Its engineering structure form generally adopts multiple groups of steel rods to form a curved surface form by grid structure or tube truss structure, which makes the appearance of the building more personalized and plays a good spatial decoration effect. At present, in the construction of special-shaped steel structure grid, each group of steel rods is assembled and installed by bolts or welding at the steel fixed installation nodes.

It can be seen that the traditional fixed installation nodes cannot be flexibly adjusted according to the direction of the steel rods. The fixing directions of different fixed installation nodes are different. Not only is the installation applicability poor, but also the structural design of the nodes is large and the production cost is high. Utility Model Content
