AI Technical Summary

Technical Problem

In steel structure engineering, the angular deformation of the flange plates of the "Y"-shaped box girder is difficult to correct, especially when the web plate is thick, the deformation caused by welding is more serious, and existing technologies cannot effectively solve this problem.

Method used

A flange angle deformation correction device of a box-shaped structure is adopted. Through the combination structure of outer plate, inner plate and connecting plate, the flange plate is slowly adjusted to the target angle by using a push-pull device such as a cylinder, and the correction is carried out by auxiliary flame heating method.

Benefits of technology

It achieves uniform force adjustment of flange angular deformation, has a simple and stable structure, and has a significant correction effect, overcoming the problem of difficult deformation correction in existing technologies.

Abstract

The utility model relates to a correction device for the wing flange angle deformation of a sub-shaped box body, which comprises two outer plates that are parallel to each other. The outer plates are connected with an inner plate through a connecting plate, and the outer plate and the inner plate are parallel to each other. A space for accommodating the wing plate of the sub-shaped box body is arranged between the outer plate and the inner plate. The distance between the two outer plates is greater than the width of the sub-shaped box body. A pushing and pulling device is arranged between the two outer plates, and the pushing and pulling device can change the distance between the two outer plates. The correction device for the wing flange angle deformation of the sub-shaped box body of the utility model is simple to manufacture and has a stable structure; the wing plate is uniformly stressed, and the correction effect is good.
