AI Technical Summary

Technical Problem

Existing old building beam and column reinforcement devices lack effective constraints on angle steel and steel plates during the reinforcement process, resulting in inconvenient installation and easy loosening, making it impossible for a single person to operate.

Method used

A reinforcement assembly is designed, comprising a first fixed half-frame and a second fixed half-frame, a limiting half-frame and a limiting plate, a reinforcing plate and a movable plate, which are fixed by bolts and welding to ensure the stability of the angle steel plate and the cross plate and to effectively limit the angle steel plate.

Benefits of technology

It achieves a stable connection between the angle steel plate and the horizontal plate, can be operated by a single person, avoids loosening of the angle steel plate and the horizontal plate during the reinforcement process, and improves reinforcement efficiency and safety.
