AI Technical Summary
The existing integrated bathroom's same-floor drainage method results in a base height of at least 15cm, which requires a large amount of material, has a limited scope of application, and traditional waterproofing techniques have high construction requirements, are prone to water seepage at the joints, and have poor waterproofing effect.
The system employs a multi-layered drainage design, using aluminum frame and multi-layered basin bottom aluminum to form a three-layered closed structure. Combined with a waterproof coating and screw fixing, it forms a waterproof structure that is low in the middle and high around the perimeter, achieving a tight fit of the waterproof coating. The multi-layered basin bottom aluminum is fixed to the aluminum frame aluminum with screws, eliminating the need for a central connecting pipe and reducing the base height.
It achieves material savings, wider applicability, better waterproofing effect, and high construction efficiency, enabling continuous construction without waiting for the waterproof coating to dry, thus shortening the construction period.

Abstract
Description
Technical Field
[0001] This invention relates to the field of integrated bathrooms, and in particular, to the prefabricated structure and prefabrication method of the bottom layer of the multi-layer drainage system for integrated bathrooms. Background Technology
[0002] Bathrooms have two drainage methods: same-floor drainage and cross-floor drainage. The principle of same-floor drainage is that sewage on the same floor is collected through pipes and then discharged into the sewage pipe of the next floor. The principle of cross-floor drainage is that sewage of the same type from each floor is discharged into the main sewage pipe through pipes.
[0003] Integrated bathrooms, due to their piping setup, are generally suitable for older buildings or self-built houses in rural areas. Therefore, they typically use in-floor drainage. The disadvantages of in-floor drainage compared to off-floor drainage are as follows: In-floor drainage requires the sewage to be collected on the same floor before being discharged into the sewage pipes of the next floor. Therefore, the base of the bathroom needs to be at least 15cm high; otherwise, it cannot effectively collect sewage on the same floor before being discharged into the sewage pipes of the next floor, which may cause sewage backflow. On the one hand, the base layer is thicker and requires more materials. On the other hand, since the pipes are collected on the same floor, the base layer uses a fully enclosed structure to protect the collected pipes, which also requires more materials. Finally, the bottom of the bathroom in commercial housing is reserved with 6-7cm, which makes it impossible for integrated bathrooms to use in-floor drainage, thus limiting their applicability.
[0004] like Figure 4 As shown: Existing integrated bathrooms, due to their structural design, include tiles 7, base surface 03, integrated pipes 04, and supporting base 05. The base surface 03 serves as the waterproof layer, which, after aging, is prone to leaks. Figure 3 As shown: Traditional waterproofing methods involve laying a waterproof fabric with a lower center (01) and higher edges (02) on the bare bathroom floor. The center (01) easily adheres to the floor due to gravity and is easy to position, while the edges (02) adhere to the wall. However, under gravity, they cannot adhere perfectly to the wall, and the seams around the edges are also ineffective and cannot be fixed. A waterproof coating is then applied to the waterproof fabric, and once the coating dries, it achieves waterproofing. However, firstly, the waterproof fabric is spliced (because the shapes of each bathroom are different, there is no one-piece waterproof fabric), so the seams of the spliced waterproof fabric around the edges are not well-fitted, which requires higher skill from the installer. Improper installation can result in large gaps between the spliced waterproof fabrics, allowing water to seep out and leading to poor waterproofing. Secondly, existing waterproofing processes cannot proceed to the next step before the waterproof coating dries, making continuous construction impossible.
[0005] In summary, the present invention aims to provide an integrated prefabricated structure and method for a non-linear drainage system in bathrooms, which features efficient installation, material savings, wider applicability, and better waterproofing. Summary of the Invention
[0006] The purpose of this invention is to address the shortcomings of existing technologies and, at least to a certain extent, solve the technical problems in related technologies by providing an integrated prefabricated structure for the bottom layer of bathroom drainage, so as to achieve the goals of saving materials, having a wider range of applications, and better waterproofing.
[0007] The integrated bathroom's subfloor drainage prefabricated structure includes several hollow aluminum frames with raised platforms on their surfaces. These frames are connected end-to-end to form a region covered with a waterproof coating, the edges of which adhere to the raised platforms. A hollow subfloor basin is mounted on each of the frame aluminum frames. Two protrusions are located on the bottom sides of the basin, forming a groove between them that fits the raised platforms. The raised platforms are confined within the grooves, ensuring the waterproof coating adheres to their surface. The basin is fixed to the frame aluminum frames with screws that extend into and secure it to the bathroom floor. The region is filled with gravel, and tiles are laid on top of the gravel. The height between the basin and the bathroom floor is 6-7 cm, and the height between the tiles and the bathroom floor is 3-4 cm.
[0008] Furthermore, the frame aluminum material is provided with several first screw holes facing each other vertically, the bottom of the layered basin aluminum material is provided with several second screw holes facing each other, and the bottom of the layered basin aluminum material is provided with a hollow space above the second screw holes.
[0009] Furthermore, the edges of the waterproof coating are respectively attached to the inner surface, upper surface, and outer surface of the raised platform. After the screws are fixed, the bottom of the groove makes the waterproof coating on the upper surface of the raised platform fit smoothly, and the two protrusions make the waterproof coating on the inner and outer surfaces of the raised platform fit smoothly.
[0010] Furthermore, the bottom of the groove is provided with several rows of equidistant first sealing protrusions on both sides, and the protrusion platform is provided with several rows of equidistant second sealing protrusions on both sides, with the first sealing protrusions located above the second sealing protrusions.
[0011] Furthermore, the two ends of the aluminum frame have corner joints, and the corner angle in the region is the sum of the corner angles of the two connected aluminum frame members, and the corner angles of the two connected aluminum frame members are the same.
[0012] The purpose of this invention is to address the shortcomings of existing technologies and, at least to a certain extent, solve the technical problems in related technologies by providing a prefabricated method for integrated bathroom drainage system to achieve rapid installation.
[0013] The prefabrication method for the bottom layer of an integrated bathroom with a non-level drainage system includes the following steps:
[0014] a. Measure the dimensions of the bathroom area and assemble the area using aluminum frame materials according to the site conditions;
[0015] b. After the aluminum frame is assembled into a region, a waterproof coating is used to cover the assembled region to form a waterproof structure that is low in the middle and high around the perimeter.
[0016] c. Before the waterproof coating dries, the aluminum material of the non-layer basin bottom is fixed from top to bottom with screws to the aluminum material of the frame. After the frame aluminum material dries, it forms a three-layer closed structure with the non-layer basin bottom aluminum material on top, the waterproof coating in the middle, and the frame aluminum material at the bottom to the bathroom floor.
[0017] d. Level the bathroom floor using gravel and then lay the tiles.
[0018] e. The entire area is now a waterproof and leak-proof base.
[0019] The main technical effects of this invention are reflected in the following aspects: 1. Through the differential drainage design, the base design is reduced, which is compatible with the current bathroom areas of commercial housing and self-built houses where there is no height difference, making it more widely applicable. 2. This invention can save the materials required for the existing bathroom floor and allows for personalized selection of bathroom size areas to effectively combine space. 3. Moreover, the edge of the waterproof coating adheres to the surface of the raised platform (including the outer surface, upper surface, and inner surface), achieving a waterproof structure that is low in the middle and high around the perimeter, resulting in excellent waterproof effect. A groove is formed between the two protruding pieces to fit the raised platform. The raised platform is confined within the groove, ensuring that the waterproof coating on the surface of the raised platform (including the outer surface, upper surface, and inner surface) is adhered. The edge of the waterproof coating is pressed tightly and adhered, especially the seams between the waterproof fabrics spliced around the perimeter, which are pressed tightly and adhered. After the waterproof coating dries, excellent waterproof effect is achieved. 4. While the waterproof coating is still wet, screws are used to fix the aluminum profiles of the non-layered basin base and frame, clamping them together. Once the waterproof coating has dried, a three-layer closed structure is achieved: the non-layered basin base aluminum profile on top, the waterproof coating in the middle, and the waterproof frame aluminum profile at the bottom, resulting in better waterproofing. 5. This method eliminates the need to wait for the waterproof coating to dry. Bathroom wall panels can be installed directly on the non-layered basin base aluminum profile, followed by doors, electrical wiring, and plumbing. This allows for continuous construction. Once the waterproof coating has dried, step d can be performed, and then shower equipment can be installed on the tiles to form an integrated bathroom. This efficient production process shortens the construction period and improves efficiency. Attached Figure Description

[0025] The embodiments of the present invention are described in detail below, and are intended to explain the present invention so that the technical solutions of the present invention are easier to understand and master, but should not be construed as limiting the present invention.
[0026] like Figure 1 , Figure 2 The integrated bathroom drainage system features a prefabricated bottom structure comprising several aluminum frame members 1. Each aluminum frame member 1 is hollow inside and has a raised platform 2 on its surface. The hollow interior contributes to the product's lightweight design. Several aluminum frame members 1 are connected end-to-end to form a region, which can be rectangular, square, trapezoidal, etc., depending on the site dimensions. This region is covered with a waterproof coating 3, and the edges of the waterproof coating 3 adhere to the surface of the raised platform 2 (including the outer, upper, and inner surfaces), creating a waterproof structure that is low in the middle and high around the edges, achieving excellent waterproofing. The aluminum frame members 1 are equipped with hollow, multi-layered basin bottom aluminum members 4, also contributing to the product's lightweight design. Two protrusions 41 are located on both sides of the bottom of the multi-layered basin bottom aluminum member 4, forming a groove 42 between the two protrusions 41 that fits the raised platform 2. The raised platform 2 limits… The waterproof coating 3, located within the groove 42, adheres to the surface of the raised platform 2 (including the outer, upper, and inner surfaces). The aluminum material 4 of the multi-layer basin bottom and the aluminum material 1 of the frame are fixed with screws 5, which extend into and fix the basin bottom to the bathroom floor. The area formed by the aluminum material 1 of the frame is filled with sand and gravel 6, and tiles 7 are laid on the sand and gravel 6. Through the multi-layer drainage design, the same-layer drainage collection pipe is eliminated, so that the height H between the multi-layer basin bottom aluminum material 4 and the bathroom floor is only 6-7cm, and the height h between the tiles 7 and the bathroom floor is only 3-4cm. This lowered base design is compatible with the current bathroom areas of commercial housing and self-built houses where there is no height difference, making it more widely applicable. This invention can save the materials required for the existing bathroom bottom and effectively combine the space of the bathroom area with personalized selection of bathroom size.
[0027] like Figure 2 As shown: The frame aluminum material 1 has several first screw holes 11 facing each other vertically, the bottom of the non-layer basin bottom aluminum material 4 has several second screw holes 43 facing the first screw holes 11, and the bottom of the non-layer basin bottom aluminum material 4 has a hollow 44 located above the second screw holes 43. The hollow 44 facilitates the driving of screws 5. The screws 5 pass through the hollow 44, the second screw holes 43, and the two first screw holes 11 in sequence, and are drilled into the bathroom floor to achieve fixation, which plays a role in efficient fixation.
[0028] like Figure 2 and Figure 5As shown: The edges of the waterproof coating 3 are respectively attached to the inner surface, upper surface, and outer surface of the raised platform 2. After the screws 5 are fixed, the bottom of the groove 42 makes the waterproof coating 3 on the upper surface of the raised platform 2 fit snugly. The left and right protrusions 41 press the waterproof coating 3 on the inner and outer surfaces of the raised platform 2 tightly and snugly. Through the above design, the edges of the waterproof coating 3 are pressed tightly and snugly, especially the seams between the waterproof cloths spliced around the perimeter are pressed tightly and snugly. After the waterproof coating dries, the waterproof coating between the seams is cured, achieving an excellent waterproof effect.
[0029] like Figure 2 and Figure 5 As shown: When the waterproof coating is not dry, the aluminum material 4 of the non-layer basin bottom and the aluminum material 1 of the frame are fixed by screws 5 and clamped together. Several rows of first sealing protrusions 45 are provided on both sides of the bottom of the groove 42, and several rows of second sealing protrusions 12 are provided on both sides of the protrusion platform 2. The first sealing protrusions 45 are located above the second sealing protrusions 12. When the waterproof coating is dry, the aluminum material 4 of the non-layer basin bottom and the aluminum material 1 of the frame are tightly bonded to the waterproof coating 3, realizing a three-layer closed structure with the aluminum material 4 of the non-layer basin bottom on top, the waterproof coating 3 in the middle, and the waterproof frame aluminum material 1 at the bottom, which has a better waterproof effect.
[0030] Both ends of the aluminum base 4 and the frame aluminum 1 have corner joints 13. The corner angle in the area is the sum of the corner joint angles 13 of the two connected frame aluminum 1s. The corner joint angles 13 of the two connected frame aluminum 1s are the same. Figure 1 As shown: the angle of the two corners is 45 degrees, and the corner angle in the area is 90 degrees, which perfectly realizes the transition of the corner.
[0031] The purpose of this invention is to address the shortcomings of existing technologies and, at least to a certain extent, solve the technical problems in related technologies by providing a prefabricated method for integrated bathroom drainage system to achieve rapid installation.
[0032] The prefabrication method for the bottom layer of an integrated bathroom with a non-level drainage system includes the following steps:
[0033] a. Measure the dimensions of the bathroom area and assemble the area using aluminum frame material 1 according to the site conditions. The shape of this area can be rectangular, square, trapezoidal, etc.
[0034] b. After the aluminum frame 1 is assembled into an area, the area of the aluminum frame 1 assembly is covered with a waterproof cloth, and then a waterproof coating is evenly applied to the waterproof cloth. After the waterproof coating dries, a waterproof structure with a low center and a high perimeter is formed.
[0035] c. Before the waterproof coating dries, the aluminum material 4 of the non-layer basin bottom is fixed to the frame aluminum material 1 from top to bottom by screws 5. After the waterproof coating dries, it adheres to the aluminum material 4 of the non-layer basin bottom to the bathroom floor, forming a three-layer closed structure with the aluminum material 4 of the non-layer basin bottom on top, the waterproof coating 3 in the middle, and the frame aluminum material 1 at the bottom. The waterproof structure is also that the edges of the waterproof coating 3 are pressed tightly around the perimeter.
[0036] d. After the waterproof coating has dried, the bathroom floor is leveled by laying sand and gravel 6, and then the tiles 7 are laid flat.
[0037] e. The entire area is now a waterproof and leak-proof base.
[0038] This method uses the aluminum base 4 and frame 1 of the multi-layer basin as the surrounding base, allowing for the installation of doors, electrical circuits, water pipes, etc. on the bathroom wall panels without waiting for the waterproof coating to dry. Then, the bathroom wall panels are installed on the multi-layer basin base 4, achieving continuous construction. After the waterproof coating dries, the area is leveled by laying sand and gravel 6, and then the tiles 7 are laid flat. Finally, the shower equipment is installed on the tiles 7, forming an integrated bathroom. This efficient production process shortens the construction period and improves efficiency.
[0039] Of course, the above are just typical examples of the present invention. In addition, the present invention may have many other specific embodiments. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by the present invention.
