Description

Technical Field

[0001] The invention relates to the technical field of integral bathroom chassis, and in particular to an integral bathroom chassis with integrated drainage. Background Art

[0002] There are usually two ways of drainage for integrated bathrooms: same-floor drainage and interlayer drainage. When using same-floor drainage, the drainage pipe is below the integrated bathroom chassis (above the caisson bottom plate), and when using interlayer drainage, the drainage pipe is below the floor slab. Whether it is same-floor drainage or interlayer drainage, the drainage pipe needs to be installed and connected on site. According to statistics, the number of joints in the drainage pipe system of conventional bathrooms ranges from 30 to 50. The on-site installation is difficult, quality control is very difficult, and the probability of local leakage is very high. Since the waterproof chassis of the integrated bathroom is almost 100% watertight, the leakage problem of the external pipe system is the key technical point to be solved by the integrated bathroom waterproof system. To this end, the patent number 201510256341.X and the patent name "An Integrated Drainage Integrated Bathroom Waterproof Chassis" announced a solution to pre-embed square drainage pipes and water seal joints into the interior of the integrated bathroom chassis. This solution is combined with glass fiber reinforced plastic technology and has excellent performance. However, in the actual project promotion process, since the flat pipe is not a national standard drainage pipe, it is difficult to promote it. Summary of the invention

[0003] The purpose of the present invention is to overcome the above problems existing in the prior art and provide an integral bathroom chassis with integrated drainage.

[0010] Wherein, the decorative surface material layer is ceramic tile or marble.

[0011] Preferably, the integrated drainage system is coated with a polyurethane layer, which forms a waterproof structure around the integrated drainage system to reduce the risk of leakage of the overall bathroom chassis.

[0012] Wherein, the PVC pipe includes a PVC straight pipe, a PVC elbow joint, and a PVC three-way joint.
