Background technique

In the prefabricated bathroom floor system, the waterproof problem needs to be considered when the bottom box is connected to the water pipe. Generally, the bottom box and the drainage fittings are installed together to play a waterproof role. In the prior art, most of the drainage fittings and the bottom box are glued together. When using the adhesive, it relies too much on the gluing method of workers. When the glue is filled, there are likely to be pores, which may lead to late-stage water leakage. The accessories are not integrated and adapted, and it is inconvenient to organize on the construction site.

At the same time, according to different partitions of the bathroom, there are sewer pipes of different diameters. Generally speaking, 50 sewer pipes are used in the dry area, and 75 sewer pipes are used in the wet area due to the increase of drainage volume. Considering the waterproof level of the sewer pipes of different pipe diameters Different, the performance requirements of the adhesive are relatively high, and it is impossible to meet the installation of a variety of waterproof bottom boxes with one adhesive. When the adhesive is installed, it is relatively simple, and the aging of the adhesive can easily lead to the decline of the bonding performance.
