Description

Limiting device for U-shaped long steel beam Technical Field The utility model relates to the field of welding tools, in particular to a limiting device for a U-shaped long steel beam. Background Compared with a concrete beam, the steel structure beam has the advantages of strong bending resistance, high shock resistance, high structural stability and the like. The current U-shaped steel beam consists of two parallel webs which are vertically arranged and a bottom plate which is connected to the bottoms of the two webs, and the webs and the bottom plate are formed by welding. But at present in the welding process of U shaped steel roof beam, put and fixed work between web and the bottom plate is comparatively loaded down with trivial details to can not be accurate assurance web and the bottom plate between perpendicular, cause the finished product inequality after the welding easily, cause the waste of resource.
