Pipe runs through concrete floor waterproofing structure

Abstract

The invention discloses a waterproof structure with a pipeline penetrating through a concrete floor. The waterproof structure comprises a process hole pre-formed in the floor and fine concrete filled in the process hole after a pipeline is mounted, wherein the process hole is formed by sleeving two or more sectional conical hole parts which are different in size and coaxial; both of the conical holes arranged vertically adopt structures that the upper parts are bigger and the lower parts are smaller; the larger end of the lower sectional conical hole extends into the upper sectional conical hole; the sleeving parts of the two conical holes are connected integrally through a bevel step of which the inner part is higher and the outer part is lower. According to the waterproof structure, the fine concrete can be filled between the process hole and the pipeline after the mounted pipeline is fixed; after the fine concrete solidifies, the built-in bevel step is formed; the bevel step can not only prevent the fine concrete from shrinking radially and axially, but also can form a labyrinth water stopping structure so as to ensure the leakproofness of the floor; the waterproof structure can be used for a water feeding pipeline to penetrate through the concrete floor, and can also be suitable for a wireway, an air channel and the other pipelines to penetrate through the concrete floor.

Description

technical field [0001] The invention relates to a waterproof structure between floors of a house, in particular, the invention relates to a waterproof structure with pipes penetrating through concrete floors. Background technique [0002] When pouring concrete floors in construction projects, it is necessary to reserve a process hole for the upper and lower water pipes to pass through according to the design position, and then fill the vacant process hole with fine stone concrete after the upper and lower water pipes are installed in place. Most of the process holes reserved in construction projects are cylindrical through holes, and occasionally conical through holes with large top and small bottom. The process holes of these shapes are simple in structure and easy to manufacture. After filling, the process holes can be effectively blocked. and gaps between pipes. However, due to the lack of radial limit structure and axial waterproof structure in the process holes of the ...

AI Technical Summary

Problems solved by technology

However, due to the lack of radial limit structure and axial waterproof structure in the process holes of the prior art, most of the reserved process holes on the floors of residential buildings in reality have water seepage problems after filling. When the fine stone concrete is cured, it shrinks without hindrance, resulting in a small gap between the fine stone concrete and the concrete floor and pipes. Once the floor accumulates water, the water will seep through the small gap to the downstairs, and the excessive seepage will inevitably cause neighborhood disputes.
