Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sanitary waterproof structures, in particular to a toilet down-lying waterproof structure. Background Art
[0002] There are two methods for waterproofing the bathroom floor in conventional buildings: (1) According to the designed thickness of the bathroom surface layer, the waterproof structure height is reserved. After the designed building thickness is reserved for the reinforced concrete slab descending plate of the bathroom floor, a waterproof layer, drainage pipes and building surface layer are constructed on it; (2) According to the designed thickness of the bathroom surface layer, the structural height is reserved. After the designed building thickness is reserved for the reinforced concrete slab descending plate of the bathroom floor, a fixed drainage pipe mortar layer, waterproof layer and building surface layer are constructed on it.
[0003] The above construction method has limitations: (1) The horizontal pipe of the bathroom drainage pipe will be left in the lower ceiling. If the drainage pipe leaks or is damaged in the future, the users on this floor will need to occupy the space of the users on the lower floor and stand in the bathroom of the lower floor to repair the bathroom of the users on the upper floor. Coordination is very difficult, there are many conflicts of interest, and construction is difficult; (2) The bathroom anti-leakage effect is poor. After the waterproof layer and drainage pipe buried in the concrete layer have leaks, it is particularly difficult to check the location of the leak. It is impossible to accurately find the leak, which makes repair difficult and the construction cost high; (3) The waterproof layer and ground construction are greatly affected by workers, there are many construction processes, many cross-processes, and it is difficult to protect the finished product. It is easy to damage the waterproof layer and cause leakage. The quality is difficult to control and the waterproof effect is poor. Utility Model Content
[0004] The utility model provides a toilet bottom-lying waterproof structure, aiming to solve the technical problems of unreasonable floor structure design, easy leakage, difficult to find leakage point, great difficulty in repair and high repair cost in building toilets.
[0005] To achieve this technical purpose, the utility model adopts the following scheme: a toilet lower lying waterproof structure, including a structural floor, which is connected to the structural bottom plate through a structural side wall to form a concave lower lying structure; a side wall groove is opened in the middle of the structural side wall, and a first waterproof layer is jointly laid on the inner wall of the side wall groove, other inner walls of the lower lying structure and the upper surface of the structural floor around the lower lying structure; a support tube is placed on the structural bottom plate, a flat plate is connected above the support tube, the edge of the flat plate is embedded in the side wall groove, a toilet drainage pipe is laid in the space below the flat plate, and a leveling layer, a second waterproof layer and a building surface layer are laid in sequence from bottom to top above the flat plate.
[0006] Compared with the prior art, the utility model has the following beneficial effects: the horizontal pipe of the drainage pipe in the structure is between the overhead layer and the structural bottom plate, and is retained on the current floor. The drainage pipe below the overhead layer is visible. When leakage occurs, the floor plate of the current floor is removed to the size of a manhole, and the construction personnel can enter the space between the overhead layer and the structural bottom plate to check the drainage pipe condition, accurately and quickly determine the location of the leakage point, and the maintenance operation is simple and convenient, and the maintenance cost is low. The flat plate and the structure above are supported by the support tube, and there is no need to pour concrete between the overhead layer and the structural bottom plate, which meets the structural strength while reducing the deadweight.
[0007] The preferred embodiment of the present utility model is:
[0008] The outer edge of the second waterproof layer extends to the edge of the first waterproof layer of the structural floor, and the double waterproof layer ensures the waterproof effect.
[0009] The depth of the underlying structure is 500~1000mm, and the drainage pipes are retained on this floor. The elevated floor meets the height requirements for manual entry to find leaks, so that the drainage pipes appear within the field of vision, and the location of the leak can be accurately and quickly determined, making maintenance easier.
[0010] The support tube is a pipe structure with concrete poured inside.
[0011] Foamed concrete is poured around the drainage pipe, which fixes the drainage pipe and provides insulation. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] In order to fully understand the purpose, features and effects of the present invention, the present invention is described in detail through the following specific implementation methods, but the present invention is not limited thereto.
[0015] like Figure 1As shown, the utility model provides a toilet bottom-lying waterproof structure, including a structural floor 1, a structural side wall 3 and a structural bottom plate 2. The structural floor 1 is connected to the structural bottom plate 2 through the structural side wall 3 to form a concave bottom-lying structure, and the bottom-lying structure covers the entire toilet. A first waterproof layer 8 is laid on the bottom-lying structure and the surrounding structural floor 1, a support tube 4 is placed in the bottom-lying structure, a flat plate 6 is connected to the support tube 4, and a drainage pipe 7 is laid in the space below the flat plate 6; above the flat plate 6, from bottom to top, there are a leveling layer 9, a second waterproof layer 10, and a building surface layer 11.
[0016] The distance between the structural bottom plate 2 of the lower structure and the structural floor 1 is 500~1000mm. In some preferred application examples, a side wall groove 5 is opened in the middle of the structural side wall 3 to extend the side wall seepage path for installing the flat plate 6. The upper surface of the structural floor 1 adjacent to the lower structure, the inner wall of the structural side wall 3 and the side wall groove 5, and the upper surface of the structural bottom plate 2 are jointly laid with waterproof rolls to form a first waterproof layer 8. The support tube 4 is evenly distributed in the lower structure. The support tube 4 can specifically adopt a vertical pipe structure of cast concrete, or other support cylinders that meet the structural strength. Adhesive is applied to the top surface of the support tube 4 to firmly bond the flat plate 6. The edges of the flat plate 6 are embedded in the side wall groove 5, and caulking paste is applied. The support tube 4 serves as the supporting structure of the overhead layer to ensure that the flat plate 6 is reasonably and stably stressed. The upper surface of the flat plate 6 is made of building concrete or mortar or other materials as a leveling layer 9, and the leveling layer 9 and the flat plate 6 together constitute an overhead layer. The upper surface of the leveling layer 9, the structural side wall 3 above the leveling layer 9 and the structural floor 1 adjacent to the lower structure are jointly laid with waterproofing membrane to form a second waterproof layer 10. The upper surface of the second waterproof layer 10 is made into a building surface layer 11.
[0017] When a water leak occurs in the bathroom, part of the building surface layer 11 of this floor is planed off, and the construction workers enter the space between the overhead layer and the structural bottom plate 2 to visually see the leakage location, quickly and accurately find the leakage point, and carry out repair construction. There is no need to coordinate and negotiate with the residents on the lower floors for repairs, and it does not involve the interests of others. The repair time is arbitrary, the workload of breaking is small, the search is fast and accurate, the repair construction is simple, the construction speed is fast, and the repair cost is low, which has practical application value.
[0018] Finally, it should be noted that the above-listed examples are only preferred embodiments of the present invention. Of course, those skilled in the art can make changes and modifications to the present invention. If these modifications and modifications fall within the scope of the claims of the present invention and their equivalent technologies, they should be considered to be within the scope of protection of the present invention.
