AI Technical Summary

Technical Problem

The safety protection effect of the existing reserved holes is unstable and easy to be kicked open. The later sealing process is complicated and there are problems such as leakage and cracks, which affects the construction safety and quality.

Method used

The inner peripheral wall of the reserved hole is designed to have a bearing surface that gradually shrinks from top to bottom. There are multiple holes on the bearing surface. The insert rod inserted into the hole is closed by using a protective member to insert the insert rod. The protection includes a protective plate and a U-shaped rib or prefabricated block and a steel mesh. The stability is enhanced by the insert rod and fixed with structural glue when necessary.

Benefits of technology

It improves the stability of the protective parts, prevents them from being kicked away, simplifies the sealing process, improves construction efficiency and safety, reduces safety hazards, and enhances construction quality and economic benefits.

Abstract

The invention discloses a reserved hole protection structure and method. In the reserved hole protection structure, the inner peripheral wall of the reserved hole is provided with a socket surface which is gradually shrunk from top to bottom, the socket surface is provided with a plurality of holes, and the center line of each hole is parallel to the center line of the reserved hole. The reserved hole is sealed by a protection piece, a plurality of insertion rods are arranged on the protection piece, and the insertion rods are inserted into the holes respectively. According to the reserved hole protection structure, the insertion rod is inserted into the hole, so that the stability of the protection part is improved, the protection part is effectively prevented from being kicked away, and meanwhile, the protection part is also convenient to disassemble quickly so as to meet the subsequent construction requirement.
