Description

Technical Field

[0001] The utility model belongs to the technical field of construction, in particular to a bathroom caisson structure based on light brick backfill. Background Art

[0002] The main design and construction of existing floor bathrooms generally adopt a caisson-type bathroom design structure. The caisson is generally backfilled with construction waste. After the bathroom caisson is backfilled, a cavity needs to be opened above the backfill layer to place the squat toilet. The current cavity is generally opened directly by manually digging the backfill layer. The cavity of this structure is prone to water seepage problems, increasing the load on the bathroom, and easily causing odor after long-term use.

[0003] For fine-decorated houses with higher quality requirements, lightweight foamed cement is generally used in batches to backfill the bottom of the bathroom box in an integrated foamed manner. However, using foamed concrete for all fillings will increase costs. Therefore, how to further reduce construction costs while ensuring the same construction quality is a challenge that needs to be faced. Utility Model Content

[0007] As a further improvement of the above solution, a groove is provided on the lightweight brick layer; the groove is filled with a foamed concrete layer; and the installation cavity is located above the groove.

[0008] The technical effect of this improvement is that it enhances the overall stability of the structure while reducing its weight. Because both lightweight bricks and foamed concrete are lightweight materials, the groove design further reduces the amount of foamed concrete required and allows the foamed concrete layer to be tightly bonded to the lightweight brick layer, improving the structure's load-bearing capacity.

[0009] As a further improvement of the above solution, the waterproof layer forms a closed cavity; the lightweight brick layer and the foamed concrete layer are both located in the cavity.

[0010] The technical effect of the above improvement is: by forming a closed waterproof cavity, it can effectively prevent moisture from penetrating, protect the structure from moisture erosion, reduce the load on the bathroom, and extend the service life.

[0011] As a further improvement of the above solution, mortar or foamed concrete is filled between the installation cavity and the squat toilet.

[0012] The technical effect of the above improvement is that this filling method can ensure the installation stability of the squat toilet.

[0013] As a further improvement of 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.

[0014] The technical effects of the above improvements are: increasing the aesthetics of the structure, while the mortar layer and the decorative brick layer provide additional protection to prevent the upper structure from causing damage to the waterproof layer.

[0015] As a further improvement of the above solution, an inner sleeve is sleeved inside the upper end of the sewer pipe; the diameter of the inner sleeve is smaller than the inner diameter of the sewer pipe, so that a gap is formed between the inner sleeve and the sewer pipe; the water hole is located higher than the lower end of the inner sleeve.

[0016] The technical effect of the above improvement is: this design can prevent the water in the squat toilet from returning to the installation cavity through the water hole, eliminating the odor problem, and at the same time allows the water entering the water hole from the installation cavity to flush the sewer pipe, preventing the excrement in the sewer pipe from clumping and causing blockage.

[0017] As a further improvement of the above solution, a groove is left in the lightweight brick layer for the installation of the horizontal section of the sewer pipe; and the lightweight bricks located above the horizontal section are placed on both sides of the lightweight bricks on both sides of the sewer pipe, so that the horizontal section of the sewer pipe will not be squeezed by the upper layer of lightweight bricks.

[0018] The technical effect of the above improvements is that it can protect the sewer pipes from being compressed by the superstructure, reduce the risk of pipe deformation and damage, and ensure the smoothness and safety of the drainage system.

[0028] As Figures 1-5As shown, the specific scheme of this embodiment is: a bathroom caisson structure based on lightweight brick backfill, including a waterproof layer 5 arranged on the inner wall of the caisson, a lightweight brick layer 10, that is, lightweight foam bricks, is arranged on the waterproof layer 5 at the bottom of the caisson, and a foamed concrete layer 2 is arranged on the lightweight brick layer 10; an installation cavity 6 cooperating with the 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; sand and gravel 12 are filled in the water guide groove 11; 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 near the bottom of the installation cavity 6.

[0029] Specifically, a waterproof layer 5 is first applied to the bottom and side walls of the caisson. After the waterproof layer 5 is dry, lightweight bricks are filled in the caisson. Lightweight bricks are generally honeycomb bricks. When filling lightweight bricks, be careful to avoid the positions of the floor drain pipe 3, the sewage pipe 1, and the sewer pipe 9. A foamed concrete layer 2 is filled above the lightweight brick 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. At the same time, a water guide groove 11 is opened on the foamed concrete layer 2. The water guide groove 11 is radially centered around the installation cavity 6. Distribution; the water guide groove 11 is used to guide the moisture that has penetrated into the foamed concrete layer 2 into the installation cavity 6 for drainage; 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, and 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 a ceramic tile. The cross-section of the water guide groove 11 generally adopts a V-shaped structure, which is filled with sand and gravel 12, and 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.

[0030] like Figure 1 As shown, as a preferred embodiment of the above embodiment, a groove is provided on the lightweight brick layer 10; the groove is filled with a foamed concrete layer 2; and the mounting cavity 6 is located above the groove.
