Primary truss and secondary truss spliced node structure

Abstract

The invention discloses a joint structure of a main truss and a secondary truss, which is composed of a main truss seat and a connecting truss. Stabilizer, the two ends of the stabilizer are provided with a limit plate, one end of the limit plate is welded and fixed with the stabilizer, and the other end of the plate is provided with a welded and fixed screw. There is a connecting buckle on the frame, one end of the connecting buckle is welded and fixed with the main frame, and round holes and threaded holes are arranged on the side wall of the connecting buckle, which are added by the stabilizing frame with double fixed structure at both ends, which strengthens the whole main frame. The support of the truss base is stable and avoids deformation due to large external forces. The connecting buckle on the main truss base is inserted into the limit locking method by the locking buckle, which is a fully closed fixing method, which can be compared with the traditional nut. The fixation has a more locking effect, and the locking force between the nut and the thread buckle can be effectively improved through the limit ring.

Description

technical field [0001] The invention relates to the technical field of truss splicing node equipment, in particular to a splicing node structure of a main truss and a secondary truss. Background technique [0002] A truss is a structure composed of rods connected by hinges at both ends. The advantage of a truss is that the rods mainly bear tension or pressure, so that the strength of the material can be fully utilized. When the span is large, it can save material compared with a solid web beam. , reduce weight and increase stiffness. According to the structure, the trusses can be divided into triangular trusses, trapezoidal trusses, polygonal trusses, vierendeel trusses and truss bridges, and can be divided into fixed trusses, folding trusses, butterfly trusses and ball joint trusses according to the product type. [0003] At present, when connecting, most of them are fixed by ordinary threaded closed structure. Since the connection form of traditional threaded equipment is...

AI Technical Summary

Problems solved by technology

[0003] At present, when connecting, most of them are fixed by ordinary threaded closed structure. Since the connection form of traditional threaded equipment is relatively simple, most of them are semi-closed fixed structures, and there is no specific limit protection device setting. When encountering external force or vibration , it is easy to cause the loosening of the screws, which makes the connection of the entire horizontal frame unstable
