Method for manufacturing a steel structure pipe truss

Abstract

The invention relates to a method for manufacturing a steel structure pipe truss, which includes a workbench, a rotating device, a rotating support device and a lifting and fixing device. Lifting fixtures are installed. The method for manufacturing steel structure pipe trusses provided by the present invention can solve the problem of first locking and fixing the column steel pipes when manually manufacturing steel structure pipe trusses, and then welding the horizontal steel pipes on the column steel pipes. During welding, only one can be welded manually at a time. Horizontal steel pipes, the positioning and fixing process of horizontal steel pipes during welding is cumbersome, and when the existing steel structure truss production equipment is manufactured, usually only one shape and specification of steel structure pipe trusses can be manufactured. When making steel structure pipe trusses of different specifications, only Fixtures cannot be replaced, which leads to problems such as low productivity of steel structure pipe trusses.

Description

technical field [0001] The invention relates to the field of steel structure manufacturing, in particular to a method for manufacturing a steel structure pipe truss. Background technique [0002] A truss is a structure made up of members connected to each other by hinges at both ends. The truss is composed of straight rods and generally has a plane or space structure of triangular units. The truss members mainly bear axial tension or pressure, so that the strength of the material can be fully utilized. When the span is large, it can save materials compared with solid web beams, reduce self-weight and Increase stiffness. The advantage of trusses is that the rods mainly bear tension or pressure, which can give full play to the role of materials, save materials, and reduce structural weight. Commonly used steel trusses, reinforced concrete trusses, prestressed concrete trusses, wooden trusses, steel and wood composite trusses, Steel and concrete composite trusses. When makin...

Problems solved by technology

[0004] (1) When the steel structure pipe truss is welded by manual welding, the column steel pipe is usually locked and fixed manually, and then the horizontal steel pipe is positioned and fixed on the column steel pipe, so that the two are welded together, and when welding , Only one horizontal steel pipe can be welded manually at a time, and the process of positioning and fixing the horizontal steel pipe during welding is cumbersome, resulting in low productivity of steel structure pipe trusses;

[0005] (2) When the existing steel structure truss production equipment manufactures the steel structure pipe truss, it usually locks and fixes the column steel pipes first, and then positions and welds multiple horizontal steel pipes on the column steel pipes at the same time, while the existing steel structure truss production The equipment can only manufacture steel structure pipe trusses of one shape and specification. When making steel structure pipe trusses of different specifications, only the fixture can be replaced.
