AI Technical Summary

Technical Problem

Traditional formwork erection methods in secondary structures suffer from problems such as poor root sealing, insecure fixing, cumbersome support, poor versatility, and difficulty in handling corners, leading to grout leakage and concrete waste.

Method used

An adjustable anti-leakage reverse sill secondary pouring formwork support system is adopted, which includes rigid formwork and elastic sealing base. Combined with adjustable support frame, the modular design and slot connection enable rapid installation and adaptable assembly of formwork. The elastic sealing base is used to fill the gap between formwork and floor slab to prevent grout leakage.

Benefits of technology

It effectively prevents grout leakage at the root, reduces concrete waste, improves installation efficiency, lowers repair costs, adapts to different curb sizes, solves the problem of grout leakage at corners, and the modular system can be reused multiple times.
