Description

Device and method for inspecting through opening of secondary truss in space pipe truss

Technical Field

Background

Trusses are structures formed by connecting rods to each other at both ends, and are generally planar or spatial structures having triangular units formed of straight rods. The pipe truss means that the rod pieces in the structure are all round pipe rod pieces. The rods in the pipe truss are mainly subjected to axial tension or pressure, so that the strength of the material can be fully utilized. The characteristics lead the material of the pipe truss structure to be economical, the dead weight to be small, and the material can be saved compared with a solid web girder when the span is larger, thereby reducing the dead weight and increasing the rigidity. In recent years, with the continuous development of the steel industry in China, pipe truss structures are widely used, such as large-span stadium buildings, exhibition centers, stadiums or other large public buildings. Most pipe truss structures employ welded connections at the rod nodes, and prior to welding, the rods to be welded are blanked and cut. Because the rod pieces in the pipe truss are intersected, the end penetrating openings of the single rod pieces are complex and irregular, and mechanical automatic cutting processing such as an intersecting line cutting machine is generally adopted in actual cutting processing. After the member on the pipe truss is completely blanked, for assembling the single pipe truss, the positioning difficulty of the pipe truss pipe orifice intersecting position is large, the rechecking inspection method is complex, time-consuming, low in efficiency and prone to error.
