Description

Technical Field

[0001] The utility model relates to the technical field of profiled steel welding, in particular to a positioning device for assisting the composite welding of profiled steel. Background Technique

[0002] The H-shaped steel is an economic section high-efficiency profile with a more optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio. It is named after its cross-section being the same as the English letter "H". Since all parts of the H-shaped steel are arranged at right angles, the H-shaped steel has the advantages of strong bending resistance in all directions, simple construction, cost savings, and light structural weight, and has been widely used.

[0003] The inner and outer sides of the flange of the H-shaped steel are parallel or nearly parallel, and the end of the flange is at a right angle, so it is named parallel flange I-beam. The web thickness of the H-shaped steel is smaller than that of the ordinary I-beam with the same web height, and the flange width is larger than that of the ordinary I-beam with the same web height, so it is also named wide flange I-beam. Determined by the shape, the section modulus, moment of inertia and corresponding strength of the H-shaped steel are significantly better than those of the ordinary I-beam with the same unit weight.

[0004] The H-shaped steel is welded by three plates. Since large mobile equipment is required to position the wing plates of the H-shaped steel during welding, and the mobile equipment occupies the working space for the welding of the H-shaped steel, the welding time of the composite welding of the H-shaped steel is increased. Therefore, in order to facilitate the normal welding of the H-shaped steel, we designed a positioning device for assisting the composite welding of profiled steel to improve the welding efficiency of the H-shaped steel.
