Description

Welding device for combined beam for building construction

Technical Field

The invention relates to the field of building construction, in particular to a welding device for a combined beam for building construction.

Background

The steel beam (H-shaped steel) is divided into a section steel beam and a combined beam, the section steel beam is directly formed by a hot rolling process, the combined beam is formed by welding or riveting two flange plates and a web plate, the flange plates are special materials for welding light H-shaped steel with different specifications and sizes, the production process for welding the H-shaped steel is optimized, plates are replaced, the shearing cost is saved, the working time is saved, and the steel consumption is saved, so that the cost for welding the H-shaped steel is greatly reduced. However, the following disadvantages exist in the welding process of the composite girder at present; 1. putting and fixing between flange board and the web are comparatively loaded down with trivial details to vertical angle between assurance flange board that can not be accurate and the web causes the finished product after the welding unqualifiedly easily. 2. The upper and lower contact surface of flange board and web contact department all need weld, need upset semi-manufactured goods after the last contact surface of flange board and web welds, then just can weld the lower contact surface of flange board and web, this process work load is big, and not only intensity of labour is big, influences the job schedule simultaneously, and the weldment work between present flange board and the web welds through the manual work mostly moreover, and is inefficient, and the cost of labor is high. Therefore, there is a high necessity for a welding apparatus for a composite girder having simple fixing and high welding efficiency to solve the above-mentioned problems.
