Description

Technical Field

[0001] This utility model belongs to the field of welding anti-deformation tooling technology, and in particular provides a device for improving the positioning of bolts at the end of the flange of welded H-beams, which is suitable for the fabrication of assembled welded H-beam brackets. Background Technology

[0002] Currently, prefabricated steel structures are widely used. However, in the fabrication of welded H-beam bracket components, welding deformation occurs, resulting in a low first-time bolt piercing rate, making subsequent adjustment work difficult and costly. Summary of the Invention

[0003] The purpose of this utility model is to provide a device for improving the positioning of bolts at the ends of welded H-beam flanges, which solves the problems of low bolt perforation rate and high operational difficulty in the current assembled welded H-beam brackets.

[0004] This utility model includes: a U-shaped support 1 and a fastening bolt 2.

[0005] The U-shaped support 1 is made of three steel plates welded together. The three steel plates are the web plate, the upper flange plate, and the lower flange plate. All three plates have holes. The fastening bolts 2 are made of high-strength bolts. The U-shaped support 1 is placed on both sides of the web plate of the H-shaped steel and fixed to the web plate of the H-shaped steel through the holes by the fastening bolts 2.

[0006] The advantages of this utility model are: the improved bolt positioning device for the end of the welded H-beam flange is simple in structure and easy to manufacture, and improves the bolt piercing rate in one go, thereby meeting the requirements of fast and safe construction of prefabricated components.
