Description

Technical Field

[0001] The utility model relates to the field of building engineering construction, in particular to a detachable building drainage pre-buried water stop joint positioning and fixing device. Background Art

[0002] The traditional process for pre-embedded water supply and drainage in the construction industry is to pre-embed steel sleeves. After the pipeline is installed, the reserved holes are sealed. This process often causes leakage due to inadequate sealing measures. In order to solve the problem of leakage caused by secondary sealing, the process of pre-embedded socket-and-spigot water-stop joints has gradually become popular in recent years. One version of the socket-and-spigot pre-embedded water-stop joint is made of PVC material, which is the same as the drainage pipe. A water-stop wing ring is provided in the middle of the water-stop joint. When pouring concrete, the pre-embedded water-stop joint is fixed on the top plate formwork, poured and embedded once, and the pipeline is installed and constructed later by means of socket-and-spigot and gluing. , effectively solving the hidden danger of leakage; the pre-buried water-stop joints for building drainage should be installed in place before concrete pouring construction. In order to ensure that the pre-buried water-stop joints are accurately positioned and firmly fixed during concrete pouring construction, the water-stop joints need to be positioned and reinforced in time. The commonly used reinforcement methods are through-thread and cover plate fixation or self-tapping screw fixation. Each pre-embedding needs to be repositioned. Although it can be effective to a certain extent, it is time-consuming, labor-intensive, and easily causes the pre-buried water-stop joints to be misaligned between the upper and lower layers, damaged, and difficult to operate, and the degree of reuse is not high.
