[0031] Currently, using the traditional wet construction method to decorate the bathroom floor has the defects of long construction period, great impact on the indoor environment, and high dependence on the technical level of workers. To overcome these defects, a technology for quickly decorating the bathroom floor by means of assembly has emerged in the prior art. Specifically, a chassis device is prefabricated in a factory, and only the whole chassis device needs to be assembled on the structural floor of the bathroom at the construction site. However, the chassis device in the prior art has the following defects: First, the overall weight of the chassis device is very large, which is not convenient for transportation; second, due to the structure and manufacturing form of the components in the chassis device, the size series of the chassis device is small. However, the sizes of different bathrooms are diverse, so the size of the chassis device sometimes cannot meet the size requirements of the bathroom. For example, chassis bodies of different sizes in the chassis device need to be made with different-sized molds, and due to the restriction of the mold opening cost, the number of the size series of the chassis body is limited.

[0032] To solve the above problems, the present invention provides a bathroom chassis structure.

[0033] Please refer to Figures 1 to 2 , in an embodiment of the present invention, the bathroom chassis structure includes a chassis main body 1 and a surface layer 2. The chassis main body 1 includes a first fiberglass polymer layer 11, a balance layer 12, a second fiberglass polymer layer 13, a slope layer 14, and a third fiberglass polymer layer 15 that are stacked in sequence. The balance layer 12 is provided with a first closed-cell structure inside; the slope layer 14 is provided with a second closed-cell structure inside; the surface layer 2 is disposed on the upper surface of the third fiberglass polymer layer 15; the first fiberglass polymer layer 11, the balance layer 12, the second fiberglass polymer layer 13, the slope layer 14, the third fiberglass polymer layer 15, and the surface layer 2 can all be cut into a preset shape.

[0034] In the above structure, by stacking the first fiberglass polymer layer 11, the balance layer 12, the second fiberglass polymer layer 13, the slope layer 14, the third fiberglass polymer layer 15, and the surface layer 2 to form a bathroom chassis structure, where the first fiberglass polymer layer 11, the balance layer 12, the second fiberglass polymer layer 13, the slope layer 14, the third fiberglass polymer layer 15, and the surface layer 2 can all be cut into a preset shape, the size specifications of the chassis structure can be modified by cutting according to the size requirements of a specific bathroom, so as to meet the needs of bathrooms with different size specifications, without relying on the manufacture of molds of different sizes, greatly reducing the mold opening cost and production cycle for small batches or home decoration, and facilitating the production of special-shaped or large-sized bathroom chassis structures. The bathroom chassis structure uses fiberglass polymer layers and the balance layer 12 and slope layer 14 with closed-cell structures. These materials have high strength and relatively low density, enabling the entire bathroom chassis structure to bear the use load of the bathroom floor while significantly reducing the weight, which is not only convenient for transportation but also can reduce transportation costs, construction costs, and construction time.

[0035] Among them, the materials of each layer can be cut and installed on-site according to bathrooms of different sizes, with strong adaptability and the ability to meet the needs of various house types. Since the first fiberglass polymer layer 11, the balance layer 12, the second fiberglass polymer layer 13, the slope layer 14, the third fiberglass polymer layer 15, and the surface layer 2 can all be cut at the construction site, there is no need to prepare a large amount of inventory for bathroom chassis structures of different sizes, thus reducing inventory costs and management complexity. And the bathroom chassis structure adopts dry construction without traditional wet operations, which not only reduces the use of water and sediment during construction, avoids environmental pollution and impacts on the indoor environment during construction, but also reduces construction time and labor requirements, and lowers construction costs.

[0036] Based on the balance layer 12 and the slope layer 14, by adding the first fiberglass polymer layer 11, the second fiberglass polymer layer 13, and the third fiberglass polymer layer 15, a multi-layer composite structure is formed, ensuring the performance complementarity of each layer of materials, providing higher structural strength and stability, and thus increasing the structural strength of the bathroom chassis structure. The synergistic effect of the multi-layer structure can effectively disperse and absorb external forces, reduce the stress concentration of single-layer materials, thereby improving the impact resistance and deformation resistance of the overall structure, and ensuring the reliability and safety of the bathroom chassis structure during long-term use. The installation process of the multi-layer structure is simple and fast, without complex construction steps and a large amount of labor. Each layer of materials can be quickly bonded or fixed, ensuring the high efficiency and reliability of the construction.

[0037] In one embodiment, the balance layer 12 includes a first extruded board; the slope layer 14 includes a second extruded board.

[0038] In the above structure, the first extruded board and the second extruded board refer to extruded polystyrene foam plastic boards, which are rigid foam plastic boards with a closed-cell honeycomb structure made by heating and melting polystyrene resin and other additives through an extrusion process and then extruding and forming, also known as XPS boards. The chassis device can be more easily carried and installed, reducing the dependence on large transportation equipment and lifting equipment, and further reducing the construction cost and time. The extruded board (XPS board) has the characteristics of light weight and high strength. Its density is relatively low, making the weight of the entire bathroom chassis structure significantly reduced. At the same time, the extruded board can be cut into a preset shape to meet the needs of bathrooms of different sizes, without relying on the manufacture of different-sized molds. The closed-cell structure inside the first extruded board and the second extruded board has good waterproof and moisture-proof properties, ensuring that the bathroom chassis structure is not easily damaged during long-term use in a humid environment.

[0039] In one embodiment, the bathroom chassis structure further includes a water retaining structure 3, and the water retaining structure 3 is arranged around the perimeter of the chassis main body 1 and / or the surface layer 2.

[0040] In the above structure, the water retaining structure 3 is arranged around the perimeter of the chassis main body 1 and the surface layer 2 to form a closed waterproof edge. The height of the water retaining structure 3 can be adjusted according to actual needs. Specifically, the water retaining structure 3 can be made higher than the surface layer 2 to prevent water from overflowing; the water retaining structure 3 is used to further enhance the overall waterproof performance of the bathroom chassis structure. The water retaining structure 3 can be made of aluminum alloy material, which has high strength and corrosion resistance, ensuring no rusting and deformation during long-term use; the water retaining structure 3 can also be made of polyvinyl chloride (PVC) material. The polyvinyl chloride material has good corrosion resistance, is easy to process and install, and the construction is fast; the water retaining structure 3 can also be made of aluminum-plastic material. The aluminum-plastic material has the characteristics of light weight and high strength, is convenient to install, and also has good corrosion resistance, suitable for humid environments.

[0041] In one embodiment, the thickness of the slope layer 14 gradually decreases from the first end to the second end.

[0042] In the above structure, the thickness of the slope layer 14 gradually decreases from the first end to the second end, forming a natural slope on the upper surface of the chassis main body 1, so that water flows naturally to the second end under the action of gravity for drainage, avoiding the formation of accumulated water and water stains.

[0043] In one embodiment, an end of the surface layer 2 close to the first end of the slope layer 14 forms a third end, a first water retaining part 31 is formed on one side of the water retaining structure 3 facing the third end of the surface layer 2, and a groove is formed between the first water retaining part 31 and the third end; an end of the surface layer 2 far from the third end forms a fourth end, a second water retaining part 32 is formed on one side of the water retaining structure 3 facing the fourth end, and the second water retaining part 32 is used for abutting against one end of the wall panel 4.

[0044] In the above structure, an end of the surface layer 2 close to the first end of the slope layer 14 forms a third end, and an end far from the third end forms a fourth end. A first water retaining part 31 is formed on one side of the water retaining structure 3 facing the third end of the surface layer 2, and a groove body is formed between the first water retaining part 31 and the third end. The groove body can be used to accommodate a sealing strip or other waterproof materials to further enhance the waterproof property. A second water retaining part 32 is formed on one side of the water retaining structure 3 facing the fourth end of the surface layer 2, and the second water retaining part 32 is used for abutting against one end of the wall panel 4, ensuring a tight connection between the water retaining structure 3 and the wall panel 4 and preventing water from seeping out from the gap between the wall panel 4 and the chassis. The third end of the surface layer 2 is the area of the lowest plane of the slope of the bathroom chassis structure. When installing the wall panel 4 in this area, since the end of the wall panel 4 and the surface layer 2 are on the same plane, the wall panel 4 does not need to be snapped into the groove body for installation, which can ensure that the height of the wall panel 4 will not be reduced due to the installation method. Exemplarily, in actual bathroom decoration, if the actual height of the wall panel 4 is 2400 mm, after installation, the height of the wall panel 4 above the surface layer 2 can still remain 2400 mm and will not be reduced to 2380 mm due to the setting of a 20-mm deep card slot.

[0045] In one embodiment, the second water retaining part 32 includes a connecting section 321 and an extending section 322. One end of the connecting section 321 is connected to the upper surface of the second fiberglass polymer layer 13, and one side of the connecting section 321 abuts against the slope layer 14, the third fiberglass polymer layer 15 and the first end of the surface layer 2; an abutting surface 3211 is formed at the end of the connecting section 321 far from the second fiberglass polymer layer 13, and the extending section 322 is connected to the abutting surface 3211; the abutting surface 3211 is spliced with the upper surface of the surface layer 2; and the abutting surface 3211 abuts against the end face of the wall panel 4.

[0046] In the above structure, one end of the connecting section 321 is connected to the upper surface of the second fiberglass polymer layer 13, ensuring the stability of the structure and the reliability of the connection; one side of the connecting section 321 abuts against the slope layer 14, the third fiberglass polymer layer 15 and the first end of the surface layer 2 to form a tight connection, so that the end of the connecting section 321 away from the second fiberglass polymer layer 13 forms an abutting surface 3211, and the abutting surface 3211 is spliced with the upper surface of the surface layer 2 to ensure the flatness of the abutting surface 3211 and the surface layer 2; the abutting surface 3211 is connected with an extension section 322, and the extension section 322 is used to abut against the end face of the wall panel 4 to ensure the tight connection between the wall panel 4 and the chassis main body 1 and prevent water from seeping out from the gap between the wall panel 4 and the chassis; the connecting section 321 and the extension section 322 enable the water blocking structure 3 to be connected to the surface layer 2 and the wall panel 4 at multiple points, forming a multi-point support structure and enhancing the stability and load-bearing capacity of the overall structure. It should be noted that the connection between the wall panel 4 and the connecting section 321 and the extension section 322 is achieved by bonding. The structure of the first water blocking part 31 is the same as that of the second side water blocking part, and it is also provided with a connecting section 321 and an extension section 322. Among them, the connecting section 321, the extension section 322 of the first water blocking part 31 and the end face of the surface layer 2 surround to form a groove body.

[0047] In an embodiment, the bathroom chassis structure further includes a sewage discharge channel 5, and the sewage discharge channel 5 penetrates through the first fiberglass polymer layer 11, the balance layer 12, the second fiberglass polymer layer 13, the slope layer 14, the third fiberglass polymer layer 15 and the surface layer 2; the sewage discharge channel 5 is located at the end with the smallest thickness of the slope layer 14.

[0048] In the above structure, the sewage discharge channel 5 is located at the end with the smallest thickness of the slope layer 14, that is, the lowest plane of the slope layer 14, and at the same time, it is also the lowest plane of the surface layer 2, which can ensure that the water flows naturally towards the sewage discharge channel 5 under the action of gravity, avoiding the formation of water accumulation and water stains on the surface layer 2. The sewage discharge channel 5 penetrates through the first fiberglass polymer layer 11, the balance layer 12, the second fiberglass polymer layer 13, the slope layer 14, the third fiberglass polymer layer 15 and the surface layer 2 to form a complete drainage path to ensure that the water can be discharged smoothly. It should be noted that the sewage discharge channel 5 can also be set at other positions according to specific needs and can be processed on site by cutting, drilling and other methods.

[0049] In an embodiment, the bathroom chassis structure further includes a sewage pipe fitting 6. The inner wall of the sewage discharge channel 5 is provided with a threaded structure, and the threaded structure is threadedly connected to the outer surface of the sewage pipe fitting 6. One end of the sewage pipe fitting 6 passing through the lower surface of the first fiberglass polymer layer 11 is used to communicate with the pipe body of the sewage system.

[0050] In the above structure, the inner wall of the sewage discharge channel 5 is provided with a threaded structure, which is used for threaded connection with the outer surface of the sewage discharge pipe fitting 6 to ensure a tight connection between the sewage pipe fitting and the sewage discharge channel 5, preventing water from seeping out at the connection. One end of the sewage discharge pipe fitting 6 that penetrates through the lower surface of the first fiberglass polymer layer 11 is used for connection with the pipe body of the sewage discharge system, so that the water flow can be smoothly discharged into the external sewage discharge system 7. The installation process of the sewage discharge pipe fitting 6 is simple and fast, without complex construction steps and a large amount of labor. Just screw the sewage discharge pipe fitting 6 into the threaded structure of the sewage discharge channel 5 and ensure connection with the external sewage discharge system 7, ensuring the high efficiency and reliability of the construction.

[0051] In one embodiment, the sewage discharge channel 5 includes a groove and a through hole that communicate with each other. The through hole penetrates through the first fiberglass polymer layer 11, the balance layer 12, and the second fiberglass polymer layer 13, and the groove penetrates through the slope layer 14, the third fiberglass polymer layer 15, and the surface layer 2; the width of the groove is greater than the width of the through hole; a limiting plate 61 is provided at one end of the sewage discharge pipe fitting 6 away from the first fiberglass polymer layer 11, and the limiting plate 61 abuts against the inner wall of one side where the groove is connected to the through hole.

[0052] In the above structure, the sewage discharge channel 5 includes a groove and a through hole that communicate with each other. The through hole penetrates through the first fiberglass polymer layer 11, the balance layer 12, and the second fiberglass polymer layer 13, and the groove penetrates through the slope layer 14, the third fiberglass polymer layer 15, and the surface layer 2. The groove and the through hole form a complete drainage path to ensure that the water flow can be smoothly discharged. The width of the groove is greater than the width of the through hole, so that the groove can accommodate more water flow and at the same time provides a larger space for installing and connecting the sewage discharge pipe fitting 6. A limiting plate 61 is provided at one end of the sewage discharge pipe fitting 6 away from the first fiberglass polymer layer 11, and the limiting plate 61 abuts against the inner wall of one side where the groove is connected to the through hole. The limiting plate 61 ensures the stable installation of the sewage discharge pipe fitting 6, preventing it from loosening or shifting during use. At the same time, the limiting plate 61 provides multi-point support for the sewage discharge pipe fitting 6, enhancing the stability and load-bearing capacity of the sewage discharge pipe fitting 6, and ensuring reliability and safety during long-term use.

[0053] In one embodiment, the chassis main body 1 further includes an adhesive layer 16, and the slope layer 14 and the second fiberglass polymer layer 13 are bonded together through the adhesive layer 16.

[0054] In the above structure, the adhesive layer 16 is located between the slope layer 14 and the second fiberglass polymer layer 13, and is used to firmly bond the two together to ensure the stability and integrity of the structure; the adhesive layer 16 can adopt high-performance waterproof adhesive materials, such as polyurethane glass fiber, waterproof film, etc., which not only have good adhesive performance, but also have waterproof and moisture-proof functions.

[0055] In one embodiment, the surface layer 2 includes tiles arranged in a matrix or the surface layer 2 includes a rigid plastic plate layer.

[0056] In the above structure, the surface layer 2 can be made of tiles arranged in a matrix, which is not only convenient for transportation and installation, but also has good wear resistance and waterproof performance. The surface layer 2 can also be made of a rigid plastic plate layer. This material is lightweight, has high strength and good waterproof performance, is easy to install, and has low maintenance costs.
