[0021] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.
[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.
[0023] like Figure 1 As shown, a residential sunken toilet elevated ground structure includes a first anti-drainage structure and a second anti-drainage structure arranged in a vertical direction, and a drainage riser passes through the second anti-drainage structure and the first anti-drainage structure in sequence.
[0024] Among them, the first anti-drainage structure includes a leveling layer 4, a waterproof layer 5, a waterproof protective layer 6 and a floor drain 3 which are sequentially made on the structural plate. The floor drain 3 is used to prevent water accumulation above the waterproof protective layer 6 in the first anti-drainage structure.
[0025] The second waterproof and drainage structure includes a waterproof base 8 and a construction adhesive layer 9 and a surface layer 10 which are sequentially manufactured on the waterproof base 8.
[0026] In the present invention, there is an overhead layer between the first anti-drainage structure and the second anti-drainage structure, and a support frame 7 for supporting the second anti-drainage structure is installed in the overhead layer, and the support frame 7 meets the installation requirements of the drainage branch pipe of the sanitary ware. The sanitary ware is installed on the surface layer 10, and the drainage branch pipe of the sanitary ware is arranged in the overhead cavity of the support frame 7 and connected to the drainage riser.
[0027] Furthermore, the structure also includes a ventilation pipe 11, which passes through the surface layer 10, the construction adhesive layer 9 and the waterproof chassis 8, and both ends of the ventilation are maintained.
[0028] Further, the second anti-drainage structure also includes a second floor drain, which is used to prevent water from accumulating above the surface layer 10. The lower end of the second floor drain can be connected to the drainage riser through a sanitary ware drainage branch pipe to drain the accumulated water on the surface layer 10 into the drainage riser. It can be understood that in order to ensure a good drainage effect, the surface layer 10 slopes toward the second floor drain.
[0029] Furthermore, the floor drain 3 is used to drain the water on the waterproof protective layer in the first anti-drainage structure into the drainage riser. The floor drain 3 sequentially penetrates the waterproof protective layer 6, the waterproof layer 5, the leveling layer 4 and the structural plate, and is connected to the drainage riser through the sleeve 1 and the integrated drainage joint 2. It can be understood that the sleeve 1 is pre-buried in the structural floor slab in advance, and the integrated drainage joint 2 is a seamless integrally formed accessory with a built-in water trap. The gap between it and the sleeve 1 is sealed with sealant (see for details). Figure 2 ), at the same time, the waterproof protective layer 6 slopes toward the floor drain 3.
[0030] It can be understood that the waterproof chassis 8 is the cushion layer of the surface layer 10, which is corrosion-resistant, strong, and not easy to deform. According to the arrangement of the drainage branch pipes of the sanitary ware, a special tool is used to open the hole, and the opening and the surrounding area are made of flanges with accessories of the same material. The flanges are reliably sealed and bonded to ensure the overall waterproof and anti-leakage performance of the waterproof chassis 8. For details, please refer to Figure 3 .
[0031] It can also be understood that the gaps between each drainage branch pipe, ventilation pipe and the waterproof chassis 8 are sealed with sealant to form a surface waterproofing.
[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
