Description

Fastener for truss connection

Technical Field

The utility model belongs to the technical field of mechanical connection structures, and particularly relates to a buckle for truss connection.

Background

The truss is a structure in which rod members are hinged to each other at both ends. The truss is a plane or space structure which is generally provided with triangular units and consists of straight rods, and the truss rod piece mainly bears axial tension or pressure, so that the strength of materials can be fully utilized, and the materials can be saved compared with a real web beam when the span is large, thereby reducing the dead weight and increasing the rigidity; the truss has the advantages that the rod piece mainly bears tension or pressure, the function of materials can be fully exerted, materials are saved, and the structure weight is reduced.

Nowadays, the connection between two rods in a truss is generally realized by punching holes on the rods and connecting the two trusses through bolts, and the method has the following disadvantages: the installation is inconvenient, the hole sites are required to be aligned, the contact area between the bolts and the rod pieces is small, the rod pieces are easy to deform, and therefore the stability of the overall structure of the truss is affected.
