[0021] The cement-based waterproof chassis 1 has an open structure at the top and is made of high-density, high-strength cement-based material. The inner surface of the cement-based waterproof chassis 1 is pre-coated with a pre-coated waterproof layer 101, which can effectively improve the waterproof ability of the waterproof chassis 1 and maintain a good waterproof effect even during construction or after long-term use.

[0022] The ground waterproofing includes: a base layer of mortar (9), a top layer of mortar (10), and a brick surface layer (11).

[0023] The bottom mortar layer 9 is placed between the cement-based waterproof base 1 and the structural floor slab 13, serving to level and bond the base layer. The top mortar layer 10 is placed between the cement-based waterproof base 1 and the brick surface layer 11, used to fix the brick surface layer 11 and provide a certain degree of elastic cushioning. The water-blocking strip 12 is fitted onto the top of the outer wall panel of the cement-based waterproof base 1 through the top mortar layer 10, serving to block water flow. The outer wall panel of the cement-based waterproof base 1 refers to the side that does not contact the wall. The bottom mortar layer 9 and the top mortar layer 10 not only fix the various structural layers but also help to disperse and buffer the stress between different material layers, improving the stability and durability of the structure, ultimately forming a multi-layered waterproof system for the ground.

[0024] An installation groove can be provided on the water-blocking strip 12 so that it can be inserted into the bottom of the bathroom glass.

[0025] The waterproofing of the wall includes: 2. compensation layer, 3. edge sealing structure, 4. cement mortar plaster layer, 5. wall waterproof coating, 6. wall mortar layer, and 7. wall tile layer.

[0026] The inner wall panel of the cement-based waterproof chassis 1 is set in the groove 141 opened at the bottom of the wall 14. The inner wall panel of the cement-based waterproof chassis 1 refers to the side that is in contact with the wall 14. This design helps to ensure a tight connection between the chassis and the wall, thereby improving the waterproof performance.

[0027] Compensation layer 2, used in the waterproof structure, provides a flexible layer capable of adapting to base deformation and displacement. It consists of a rubber layer 201 and waterproof adhesive layers 202 disposed on both sides of the rubber layer 201. The rubber layer 201 is made of a highly elastic, weather-resistant, and durable rubber material, capable of withstanding certain tension and compression, and adapting to minor displacements and vibrations of the building. The waterproof adhesive layer 202 enhances the overall waterproof performance of compensation layer 2 and is made of a special adhesive or coating material, possessing excellent adhesion and waterproofing properties. Compensation layer 2 is disposed between the cement-based waterproof base plate 1 and the inner wall of the groove 141, its function being to absorb and compensate for minor displacements caused by structural deformation, temperature changes, etc.

[0028] The edge sealing structure 3 includes: a bridging extension plate 301, a toothed sealing plate 302, and a positioning plate 303.

[0029] The bridging extension plate 301 is made of a sealing material with a certain degree of elasticity and extensibility. It is used to cross the inner wall panel of the cement-based waterproof chassis 1 to achieve a soft seal between the wall surface and the compensation layer 2, and to ensure the continuity of the seal. The positioning plate 303 and the toothed sealing plate 302 are respectively set at both ends of the bridging extension plate 301. Specifically, the toothed sealing plate 302 is set at the inner end of the bridging extension plate 301 and is used in conjunction with the compensation layer 2. The positioning plate 303 is set at the outer end of the bridging extension plate 301 and is used in conjunction with the wall.

[0030] The top of the compensation layer 2 is provided with a toothed groove, which cooperates with the toothed sealing plate 302 in the edge sealing structure 3. The design of the toothed groove can enhance the bonding force between the edge sealing structure 3 and the compensation layer 2 and prevent moisture from seeping through the joint.

[0031] A positioning groove 142 is provided at the opening of the groove 141 at the bottom of the wall 14. The positioning plate 303 is set in the positioning groove 142. The design of the positioning groove 142 can ensure that the edge sealing structure 3 can be accurately placed during the installation process, and at the same time be pre-fixed to the wall 14, so as to facilitate the subsequent insertion of the inner wall panel of the cement-based waterproof chassis 1 into the groove 141.

[0032] A sealing strip 304 is provided on the lower surface of the bridging extension piece 301, and a sealing groove 104 for accommodating the sealing strip 304 is opened on the top outer side of the inner wall panel of the cement-based waterproof chassis 1. Construction steps: First, a groove 141 is opened at the bottom of the wall 14. The size and shape of the groove 141 should match the inner wall panel of the cement-based waterproof chassis 1 to ensure a good fit. Then, the compensation layer 2 is embedded in the groove 141 and tightly fitted to the inner wall of the groove. Next, the edge sealing structure 3 is embedded in the groove 141, ensuring that the toothed sealing plate 302 engages with the toothed groove at the top of the compensation layer 2, and the positioning plate 303 is located in the positioning groove 142. Then, the cement-based waterproof chassis 1 is placed in the predetermined position, ensuring that its inner wall panel is accurately embedded in the groove 141 and pressed against the surface of the compensation layer 2, while the sealing strip 304 is embedded in the sealing groove 104. This not only improves the connection stability between the cement-based waterproof chassis 1 and the wall 14, but also enhances the sealing performance of the entire waterproof structure, thereby effectively preventing water penetration.

[0033] The cement mortar plaster layer 4 is placed above the inner wall panel of the cement-based waterproof base 1, that is, immediately adjacent to the inner wall panel of the cement-based waterproof base 1, and level with the inner wall of the inner wall panel. The main function of the cement mortar plaster layer 4 is to provide a smooth and uniform surface to facilitate the subsequent construction of the wall waterproof coating 5, and it also enhances the structural strength and stability of the wall. The wall waterproof coating 5 is placed on the surface of the cement mortar plaster layer 4 and extends to the inner wall of the inner wall panel of the cement-based waterproof base 1, so that the wall waterproof coating 5 can cover the transition area from the wall to the cement-based waterproof base 1, forming a continuous waterproof layer. The wall mortar layer 6 is placed on the surface of the wall waterproof coating 5 and is the key layer connecting the wall waterproof coating 5 and the wall tile layer 7. The wall tile layer 7 is placed on the surface of the wall mortar layer 6. The main function of the wall mortar layer 6 is to provide sufficient adhesion to ensure that the wall tile layer 7 can be firmly attached to the waterproof coating 5, and it also plays a leveling and buffering role to adapt to unevenness or slight deformation of the substrate.
