Basement outer wall post-cast strip fabricated maintenance water stop structure and construction method thereof

Abstract

The basement exterior wall post-cast strip fabricated maintenance water stop structure mainly comprises a prefabricated part, the prefabricated part is composed of a left folded panel and a right folded panel, and the lower ends of the two folded panels and a base reverse ridge at the position of a basement exterior wall post-cast strip are installed into a whole in a sealed mode; the front ends of the two folding plates are closed, clamped, sealed and fixed; the rear ends of the two folded panels are opened outwards and are provided with water-stop belts and tie bars, and the two folded panels are bound with reinforcing steel bars on the periphery of the basement through the water-stop belts and the tie bars and then poured into a whole. According to the basement outer wall post-cast strip fabricated maintenance water stop structure and the construction method thereof, the waterproofness can be improved, construction is fast, the waterproofness is good, and the soil pressure resistance is high.

Description

Technical field [0001] The present invention relates to the field of building construction, especially in a ground outdoor outer wall rear lane-off structure and its construction method thereof. Background technique [0002] The construction basement rear tape is poured after the building main body structure is capped. The rearward band is not only effectively preventing the crack fracture of the basement of large volume concrete due to disposable pouring, but also allows the construction main structure to release internal force before the cap, avoiding the uneven settlement of the construction caused by internal force to cause the wall cracking Or destroy. Among them, the tradition of the boiling belt in the basement is to reserve a reserved width of 60 to 80cm in the wall, and then build a C-shaped fence wrapped in the outer wall of the rear ladle. The role of the wall is to block the soil pressure on the ground pressure on the ground pressure of the ground room, and the second...

AI Technical Summary

Problems solved by technology

Although the traditional C-shaped fence method plays a certain role in waterproofing and retaining soil, the construction process is relatively complicated. The contact between the C-shaped fence and the basement wall is a lap joint, and the waterproof is weak, and it is easy to Extruded, deformed or even destroyed, the whole construction process has many procedures, the construction efficiency is low, and the post-casting belt formwork is cumbersome
