Description

Technical Field

[0001] The utility model belongs to the technical field of truss processing, and in particular relates to a clamp for processing a truss steel structure. Background Art

[0002] A truss is a structure made of rods connected to each other at both ends with hinges. A truss is a plane or space structure composed of straight rods and generally has triangular units. Truss rods mainly bear axial tension or pressure, so as to make full use of the strength of the material. When the span is large, it can save materials, reduce deadweight and increase rigidity compared to solid beams.

[0003] The advantage of the truss is that the rods mainly bear tension or pressure, which can give full play to the role of materials, save materials and reduce the weight of the structure. Commonly used are steel trusses, reinforced concrete trusses, prestressed concrete trusses, wood trusses, steel and wood composite trusses, steel and concrete composite trusses;

[0004] When installing the truss, it is necessary to use a clamp to clamp the side rods and the truss bottom plate of the truss and then connect the truss bottom plate to the side rods. However, the clamp can only clamp a single side rod at a time and the truss bottom plate needs to be manually aligned with the side rods. When the side rods at other positions are subsequently connected, it is easy for the installation position between the side rods and the truss bottom plate to deviate. Utility Model Content
