[0001] The utility model relates to node connection technical field, concretely is a node connection structure of complex pipe truss. BACKGROUND
[0002] In the field of building construction, pipe truss structure is widely used in large venues, industrial plants, bridges and other engineering due to its advantages of light weight, high strength, beautiful appearance and the like. The pipe truss is usually connected by a plurality of pipe truss bodies through a multi-directional joint to form a stable spatial structure system. However, the existing connection mode of the pipe truss body and the multi-directional joint has many drawbacks, which seriously affects the construction efficiency and quality.
[0003] However, the existing node connection structure of complex pipe truss still has some disadvantages in actual use: at present, the common connection mode of pipe truss body and multi-directional joint mainly relies on traditional bolt connection or welding mode. Bolt connection requires the operator to use a variety of complex operating tools, such as wrench, screwdriver, etc., and the installation steps are complicated. First, the pipe truss body and the multi-directional joint need to be preliminarily positioned, then the bolt holes are aligned, and then a plurality of bolts are tightened in turn. The whole process not only consumes time and effort, but also requires a high technical level of the operator. Once the bolt tightening torque is uneven, it is easy to cause unstable connection, affecting the overall stability of the pipe truss structure.
[0004] Although the welding connection mode can improve the strength of the connection to a certain extent, professional welding equipment and skilled welders are required for the welding process. The welding site needs to be strictly cleaned and pretreated before welding, and the welding parameters need to be controlled during the welding process to ensure the welding quality. In addition, welding can produce high temperature and sparks, which can easily cause fire hazards, and the use of welding connection mode is limited in some places with high fire safety requirements.
