Description

Technical Field

[0001] The present application belongs to the field of bathroom floor structures, and specifically relates to a sunken bathroom floor structure. Background Art

[0002] The sunken toilet structure is to sink the floor of the toilet to facilitate the laying of water supply and drainage pipes such as floor drains and toilets. It is widely used in residential construction because of its simple construction, free space layout, and convenient pipe laying. The sunken part of the sunken toilet structure is called a caisson structure. In the prior art, water supply pipes and drainage pipes are installed in the caisson, and usually two waterproof layers are required. One waterproof layer is arranged on the bottom surface and wall of the caisson structure, which is called the caisson waterproof layer, and the other waterproof layer is arranged on the upper part of the backfill layer after the caisson is backfilled, which is called the ground waterproof layer.

[0003] The above traditional waterproofing methods will cause three problems: First, water supply pipes are installed in the caisson, and the risk of pipe leakage is high. The cost and time of leakage repair are high, which has a great impact on the life of the owners; second, there are no protective measures above the ground waterproof layer, and the subsequent construction of the waterproof layer is easily damaged or the workmanship is not precise, which will cause the water that seeps into the waterproof layer to leak into the caisson. The seeping water will accumulate at the bottom of the caisson due to the caisson waterproof layer. Over the years, it will produce odors and breed bacteria, affecting the health of residents. It will also cause the durability of the materials or pipes of the ground structure to deteriorate, and the water at the bottom of the caisson will be extremely difficult to clean manually due to the complex ground structure; third, the seeping water will remain in the caisson for a long time, and will be absorbed by the backfill layer material, or accumulate at the bottom of the caisson, increasing the load on the floor, affecting the stability of the house structure, and bringing safety hazards; fourth, the seeping water will be stored in the caisson for a long time, and it may evaporate and return to the surface of the bathroom finishing layer, affecting the bathroom user experience, especially the dry area.

[0004] In addition, the existing bathroom backfill construction process does not perform structural load-bearing capacity reinforcement on the backfill surface. Since the backfill is usually made of loose materials with poor load-bearing capacity, such as coal slag or expanded clay, during the use of the bathroom, the backfill will sink and damage the bathroom floor structure, causing serious losses to the user.

[0005] Furthermore, the existing bathroom finishing layer brick joints are usually treated with grout or caulking agent. These materials have poor adhesion to tiles and will appear pores when used for caulking. They are easy to fall off when used in a humid environment, resulting in the risk of surface water infiltration, which is not conducive to bathroom waterproofing.

[0006] Therefore, there is an urgent need to propose a sunken toilet floor structure that can solve the water accumulation problem of the caisson and the deformation problem of the backfill layer, and provide a sunken toilet floor structure that is simple to construct, low in cost, durable, comfortable and safe.

BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Other features, objects and advantages of the present application will become more apparent by reading the detailed description of non-limiting embodiments made with reference to the following drawings:

[0025] Figure 1 : Schematic diagram of the floor structure of the sunken bathroom in this application.

[0026] In the figure: caisson structure 10, backfill layer 20, cushion layer 21, waterproof layer 22, waterproof protection layer 23, adhesive layer 24, finishing layer 25, floor drain 30, drainage cross pipe 40, pier 41, chamfer structure 50, drainage assembly 60. DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] like Figure 1 As shown, one of the embodiments of the present application is a sunken toilet floor structure, comprising: a backfill layer 20, a cushion layer 21, a waterproof layer 22, an adhesive layer 24 and a finishing layer 25 arranged in sequence from the bottom of the caisson structure 10 upward;

[0029] Wherein, the thickness of the cushion layer 21 is 40-50 mm.

[0030] The present application sets the thickness of the cushion layer 21 to 40-50 mm. The prior art often sets the thickness of the cushion layer to be thinner, such as about 20 mm. However, it is often easy to be compressed and produce deflection, and then cracks will be produced. In severe cases, it may even break, affecting the stability of the structure. It is also easy to damage the upper waterproof layer, causing water leakage in the bathroom. If it is set to be greater than 50 mm, the thickness of the bathroom floor structure will be too high, and even exceed the floor height of the room, causing the accumulated water to flow out, affecting the normal use of the room. In this embodiment, the thickness of the cushion layer 21 is set to 45 mm. The present application enhances the load capacity of the cushion layer 21 by thickening the cushion layer 21, ensuring that the floor structure will not sink when stepped on from above, relieving the bearing pressure of the backfill layer 20, improving the durability of the structure, solving the problem of water seepage caused by cracks in the bathroom due to the sinking of the floor structure, and avoiding safety hazards. The present application does not provide a waterproof layer in the caisson structure 10, which helps to drain the moisture that has leaked into the backfill layer 20 in time, prevents the moisture from being retained at the bottom of the caisson structure 10 for a long time and deteriorating and producing odor, thereby improving the comfort of bathroom use and reducing construction and maintenance costs.

[0031] Furthermore, the sunken toilet floor structure further includes: a waterproof protective layer 23, which is arranged between the waterproof layer 22 and the adhesive layer 24. Through the above arrangement, the waterproof layer 22 can be protected from being damaged and destroying its waterproof ability during subsequent construction and use.

[0032] Furthermore, the waterproof layer 22 is also arranged on the wall. Through the above arrangement, it can be ensured that the condensed water on the wall surface will not penetrate into the wall, protecting the bathroom as a whole from water seepage and leakage.

[0033] Furthermore, the sunken toilet floor structure also includes: a drainage component 60; the drainage component 60 includes a connected floor drain 30, a drainage horizontal pipe 40 and a drainage longitudinal pipe (not shown in the figure), the floor drain 30 is arranged on the finishing layer 25, and the drainage longitudinal pipe passes through the finishing layer 25, the adhesive layer 24, the waterproof layer 22 and the cushion layer 21.

[0034] Furthermore, a drainage transverse pipe 40 is provided in the backfill layer 20, and the drainage transverse pipe 40 is connected with the floor drain 30 and the drainage longitudinal pipe. The drainage transverse pipe 40 is provided to facilitate centralized drainage of sewage.

[0035] Specifically, the spacing between the piers 41 fixing the drainage transverse pipe 40 is no more than 1000 mm, and the distance from the pipe corner and the lowest point of the trap is no more than 500 mm, which helps to fix the drainage transverse pipe 40 and keep the drainage transverse pipe 40 straight, ensuring smooth drainage work.

[0036] Specifically, no water supply pipe is provided in the backfill layer 20, which helps to reduce the risk of water leakage in the pipe in the backfill layer 20, thereby reducing the possibility of leakage of the caisson structure 10. Furthermore, a chamfer structure 50 is provided between the cushion layer 21 and the wall; and / or, a chamfer structure 50 is provided between the cushion layer 21 and the drainage longitudinal pipe. The above-mentioned arrangement facilitates the processing of the inner corners when laying the materials, can ensure that the waterproof layer 22 can be smoothly laid on the cushion layer 21, and is also conducive to the fixation of the drainage longitudinal pipe. In this embodiment, a chamfer structure 50 is provided between the cushion layer 21 and the wall, and a chamfer structure 50 is provided between the cushion layer 21 and the drainage longitudinal pipe.

[0037] Furthermore, the cushion layer 21, the waterproof layer 22, the adhesive layer 24 and the finishing layer 25 are in a slope structure, wherein the slope slopes toward the floor drain 30. Through the above arrangement, the water on the ground can be quickly drained away by gravity, and the water that penetrates into the structural layers such as the adhesive layer 24 through the gaps between the floor tiles can be automatically drained.

[0038] Furthermore, the slopes of the cushion layer 21 , the waterproof layer 22 , the adhesive layer 24 and the finishing layer 25 are 1 to 3% to ensure that water can flow to the floor drain 30 in a concentrated manner.

[0039] In this embodiment, the slope of the cushion layer 21, the waterproof layer 22, the adhesive layer 24 and the finishing layer 25 is 2%.

[0040] Furthermore, the sealing material of the finishing layer 25 is made of polymer material.

[0041] Specifically, the caulking material of the finishing layer 25 is epoxy sand, which can ensure that no gaps are left when caulking, and is strong and durable, has good waterproof performance, is not easy to deteriorate, and improves the comfort of space use.

[0042] Furthermore, the backfill layer 20 is made of ceramsite concrete or foamed cement.

[0043] In this embodiment, the backfill layer 20 is made of ceramsite concrete, which is made of cement and ceramsite mixed in a mass ratio of 1:6, or a lightweight and high-strength material such as foamed cement, which improves the waterproof performance of the ground structure and will not sink locally due to construction or use, thereby damaging the waterproof layer 22. In addition, the lightweight material is not easy to damage the pipeline during the backfilling process, which can reduce the risk of water leakage in the drainage transverse pipe 40 in the caisson. Through the above arrangement, the load of the caisson structure 10 can be reduced, and it is also beneficial to fix the pipeline in the caisson structure 10.
