Description

Technical Field

[0001] This utility model relates to the field of building and related technologies, and in particular to a prefabricated toilet chassis and drainage structure. Background Technology

[0002] Currently, bathroom drainage systems are mainly categorized into in-floor drainage and out-of-floor drainage. Out-of-floor drainage prefabricated bathrooms, where the wastewater pipes from the upper floor run through to the roof of the lower floor, present numerous problems such as "property disputes" and "inconvenient maintenance." In-floor drainage is further divided into lowered-slab and non-lowered-slab in-floor systems. Lowered-slab prefabricated bathrooms typically have a 200-400mm lowered slab height, using drainage branch pipes laid under the chassis and water-sealed floor drains, which inherently introduces inherent drawbacks. Non-lowered-slab prefabricated bathrooms typically have a ≤50mm lowered slab height, with drainage branch pipes laid along the walls and water collectors pre-embedded in the original floor slab to achieve both drainage and water sealing.

[0003] Therefore, the existing technology has the following problems: 1. The existing method of laying drainage along the wall without lowering the floor slab requires pre-embedding water collection boxes in the floor slab, which is not suitable for old house renovation.

[0004] 2. When laying existing same-floor drop-down pipes under the chassis, the pipes are laid first and the chassis is installed later, which can lead to misalignment of the drainage joints due to measurement and installation errors. To solve this misalignment problem, the chassis is installed about 5cm away from the wall, which wastes the user's actual usable space. Utility Model Content

[0005] In view of this, and to solve the above problems, the purpose of this utility model is to provide a prefabricated bathroom chassis and drainage structure, comprising: Chassis, water tank body, water tank cover, floor drain assembly, and finish layer assembly; The top surface of the chassis is provided with a mounting groove, and the bottom of the mounting groove is provided with a mounting hole; The water box body is installed on the bottom surface of the chassis, and the top part of the water box body is located in the mounting hole, with a predetermined gap reserved between it and the inner wall of the mounting hole. The water box cover is housed in the mounting groove and is detachably and fixedly connected to the water box body; The finishing layer assembly is installed on the chassis and has a through hole corresponding to the mounting hole.
