TECHNICAL FIELD
[0001] The utility model belongs to the technical field of building, concretely is based on the bathroom interval caisson structure of ceramic granule backfill. BACKGROUND
[0002] The main body design construction of the existing floor bathroom generally adopts the design structure of the caisson type bathroom, and the backfill of the caisson generally adopts construction waste. After the backfill of the bathroom caisson, a cavity is formed on the backfill layer for placing a squatting closet. At present, the cavity is generally formed by manually digging the backfill layer. This structure of the cavity can easily cause water seepage problems, increase the load of the bathroom, and easily cause a return smell after long-term use.
[0003] The high-quality housing generally uses lightweight foamed cement to integrally foam and form the backfill filling of the bathroom box bottom. However, the use of foamed concrete for the entire backfill filling can increase the cost. Therefore, how to further reduce the construction cost under the premise of ensuring the same construction quality is a challenge. UTILITY MODEL CONTENTS
[0004] In view of the above problems, the utility model provides a bathroom caisson structure based on ceramic granule backfill, which can solve the problems of water seepage, increased load of the bathroom, and easy return smell of the existing bathroom caisson structure after long-term use. The drainage efficiency can be increased, the drainage pipe can be prevented from being blocked or leaking, the construction cost can be further reduced under the premise of ensuring the construction quality, and the construction speed can be improved.
[0005] To achieve the above purpose, the utility model adopts the technical scheme of:
[0006] The bathroom caisson structure based on ceramic granule backfill includes a waterproof layer arranged on the inner wall of the caisson, a ceramic granule layer arranged on the waterproof layer at the bottom of the caisson, and a foamed concrete layer arranged on the ceramic granule layer. An installation cavity matched with the squatting closet is arranged on the foamed concrete layer. A drain pipe is arranged in the installation cavity. Water guide grooves are distributed on the foamed concrete layer, and one end of the water guide groove is communicated with the installation cavity. A waterproof layer is arranged on the surface of the foamed concrete layer, the water guide groove, and the installation cavity. A mortar layer is arranged on the waterproof layer of the foamed concrete layer, and a decorative brick layer is arranged on the mortar layer. A water hole is formed in the side wall of the drain pipe.
[0007] As a further improvement of the above scheme, the waterproof layer forms a closed cavity, and the ceramic granule layer and the foamed concrete layer are both located in the cavity. By forming a closed waterproof cavity, water penetration can be effectively prevented, the structure can be protected from water erosion, the load of the bathroom can be reduced, and the service life can be prolonged.
[0008] As a further improvement of the above solution, the space between the installation cavity and the squat toilet is filled with mortar or foamed concrete, which can ensure the installation stability of the squat toilet.
[0009] As a further improvement to the above solution, a mortar layer is provided above the waterproof layer above the foamed concrete layer, and a decorative brick layer is provided above the mortar layer. This improves the aesthetics of the structure, while the mortar layer and the decorative brick layer provide additional protection, preventing the upper structure from damaging the waterproof layer.
[0010] As a further improvement to the above solution, the upper end of the drain pipe is sheathed with an inner sleeve; the diameter of the inner sleeve is smaller than the inner diameter of the drain pipe, creating a gap between the inner sleeve and the drain pipe; and the water hole is positioned higher than the lower end of the inner sleeve. This design prevents water from the squat toilet from flowing back into the installation cavity through the water hole, eliminating odor problems. At the same time, water entering the water hole from the installation cavity can flush the drain pipe, preventing fecal matter from accumulating in the drain pipe and causing blockage.
[0011] As a further improvement to the above solution, support blocks are provided within the caisson to support the horizontal section of the sewer pipe or floor drain pipe. The support blocks are bricks. This improves the stability of the sewer pipe or floor drain pipe and prevents excessive pressure on the horizontal section, which could cause the entire pipe to move downward and lead to structural instability.
[0012] Compared with the prior art, the present invention has the following technical effects:
[0013] Through the above-mentioned improvements, the utility model achieves lightweight and waterproof effects, while reducing construction costs, improving construction efficiency and quality, extending the service life of the building, and enhancing the stability and safety of the structure. These improvements work together to make the bathroom caisson structure more adaptable to the needs of modern architecture, providing users with a more comfortable, safe, and economical living environment.

[0020] In order to enable those skilled in the art to better understand the technical solution, the present invention is described in detail below in conjunction with the embodiments. The description in this section is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.
[0021] like Figure 1-5 As shown, the specific scheme of this embodiment is: a bathroom caisson structure based on expanded clay backfill, including a waterproof layer 5 arranged on the inner wall of the caisson, a expanded clay layer 10 is arranged on the waterproof layer 5 at the bottom of the caisson, and a foamed concrete layer 2 is arranged on the expanded clay layer 10; an installation cavity 6 cooperating with a squat toilet 7 is arranged on the foamed concrete layer 2; a sewer pipe 9 is arranged in the installation cavity 6; a water guide groove 11 is distributed on the foamed concrete layer 2, and one end of the water guide groove 11 is connected to the installation cavity 6; a waterproof layer 5 is arranged on the surface of the foamed concrete layer 2, the water guide groove 11 and the installation cavity 6; a mortar layer 4 is arranged on the waterproof layer 5 of the foamed concrete layer 2, and a decorative brick layer 8 is arranged on the mortar layer 4; a water hole 91 is opened on the side wall of the sewer pipe 9.
[0022] Specifically, a waterproof layer 5 is first applied to the bottom and side walls of the caisson. After the waterproof layer 5 is dry, a support block 13 is placed in the caisson to support the bottom of the sewer pipe 9 or the floor drain pipe 3, and then ceramsite is filled. A foamed concrete layer 2 is filled above the ceramsite layer 10. The thickness of the foamed concrete layer 2 is generally greater than the height of the squat toilet 7; an installation cavity 6 is opened above the foamed concrete layer 2 for installing the squat toilet 7, and a water guide groove 11 is opened on the foamed concrete layer 2. The water guide groove 11 is radially distributed with the installation cavity 6 as the center; the water guide groove 11 is used to guide the water that penetrates into the foamed concrete layer 2. The moisture on the concrete layer 2 is introduced into the installation cavity 6 and discharged; a waterproof layer 5 is arranged above the foamed concrete layer 2, and the waterproof layer 5 is also located on the surface of the water guide groove 11 and the installation cavity 6, which can prevent moisture from penetrating into the foamed concrete layer 2. Finally, a mortar layer 4 is filled above the foamed concrete layer 2, and then the decorative brick layer 8 is installed. The decorative brick layer 8 is generally ceramic tiles. The cross-section of the water guide groove 11 generally adopts a V-shaped structure and is filled with sand and gravel 12. The diameter of the sand and gravel 12 at the bottom is larger than the diameter of the sand and gravel 12 in the upper layer; the floor drain pipe 3 and the sewer pipe 9 are connected to the sewage pipe 1.
[0023] like Figure 1As shown, as a preferred embodiment of the above embodiment, the waterproof layer 5 forms a closed cavity; the ceramsite layer 10 and the foamed concrete layer 2 are both located within the cavity. Specifically, the waterproof layer 5 above the foamed concrete layer 2 and the waterproof layers 5 on the side walls and bottom of the caisson together form a closed cavity, preventing moisture from penetrating into the foamed concrete layer 2 and the ceramsite layer 10. This allows moisture in the bathroom to penetrate only below the mortar layer 4. This moisture can then enter the installation cavity 6 through the water guide groove 11 and finally drain through the water hole 91 into the sewer pipe 9.
[0024] like Figure 1 As shown, as a preferred embodiment of the above embodiment, mortar or foamed concrete is filled between the mounting cavity 6 and the squat toilet 7. To improve the structural stability of the squat toilet 7, the mounting cavity 6 is filled with mortar or foamed concrete, the squat toilet 7 is installed in the mounting cavity 6, and the excess mortar or foamed concrete that is squeezed out is removed.
[0025] like Figure 1 As shown, as a preferred embodiment of the above embodiment, a mortar layer 4 is provided above the waterproof layer 5 above the foamed concrete layer 2, and a decorative brick layer 8 is provided above the mortar layer 4. This is for installing the decorative brick layer 8, which is generally ceramic tiles.
[0026] like Figure 1 As shown, as a preferred embodiment of the above embodiment, an inner sleeve 92 is sleeved inside the upper end of the downpipe 9; the diameter of the inner sleeve 92 is smaller than the inner diameter of the downpipe 9, so that a gap is formed between the inner sleeve 92 and the downpipe 9; and the water hole 91 is positioned higher than the lower end of the inner sleeve 92. The drain outlet of the squat toilet 7 is connected to the upper end of the inner sleeve 92, so that flushing water from the squat toilet 7 is discharged from the inner sleeve into the downpipe 9; the inner sleeve 92 is used to isolate the sewage from the squat toilet 7 from the water hole 91, preventing water from flowing back into the installation cavity 6; and the water immersed in the installation cavity 6 is discharged from the water hole 91 into the downpipe 9, thereby draining the water in the installation cavity 6 and allowing the water in the installation cavity 6 to flush the inner wall of the downpipe 9.
[0027] like Figure 1 As shown, as a preferred embodiment of the above, a support block 13 is provided in the caisson for supporting the horizontal section of the downpipe 9 or the horizontal section of the floor drain pipe 3; the support block 13 is a brick. The brick can be a lightweight brick.
[0028] The specific working principle of this utility model:
[0029] Using ceramsite to fill the bathroom caisson reduces the amount of foamed concrete used, lowering costs. The lightweight ceramsite reduces pressure on water pipes, reducing bathroom loads and shortening caisson construction time. An inner casing 92 isolates the flushing water of the squat toilet 7 from the installation cavity 6, preventing it from entering the installation cavity 6 while simultaneously removing moisture from the cavity 6.
