Description

Technical Field

[0001] This utility model relates to the field of bathroom anti-seepage drainage design, and in particular to a bathroom anti-seepage drainage structure. Background Technology

[0002] In the field of building engineering, bathrooms, as functional areas that are constantly exposed to a damp environment, have their seepage prevention and drainage performance directly affecting the comfort of use and the durability of the structure. Whether it is a residential building, a commercial building, or a public facility, bathrooms need to deal with problems such as water accumulation on the floor, pipe leaks, and capillary water infiltration. Once the seepage prevention and drainage structure fails, it can easily lead to hidden dangers such as damp walls, moldy floors, and corrosion of structural steel bars, which not only reduces the living experience but also increases the cost of later maintenance.

[0003] Construction often involves discontinuous processes, such as pouring structural beams and slabs, waterproof retaining walls, and waterproof guide walls in stages. This can easily lead to cracks due to concrete shrinkage, creating leakage channels. Simultaneously, the waterproofing layer design lacks continuity, with improper overlap between the floor and wall waterproofing layers. Weak areas such as pipe roots and corners are not reinforced, making the waterproofing layer prone to cracking and leakage after long-term use due to moisture erosion. Inadequate drainage systems are also problematic. Many bathrooms rely solely on surface drainage, leaving water trapped under the tiles. Prolonged water accumulation accelerates waterproofing layer aging and can even seep through wall gaps. Some drainage components lack anti-clogging and odor-prevention designs, making them susceptible to blockage by impurities or water seal failure, leading to drainage failure and odor backflow. Furthermore, pipe installation often involves post-installation trenching, compromising the structural integrity of the walls, and inadequate sealing of gaps between pipes and the structure further increases the risk of moisture leakage.

[0004] In response to this technical problem, this application proposes a toilet anti-seepage and drainage structure. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a bathroom anti-seepage drainage structure that effectively prevents the waterproof layer from cracking and leaking, solves the problem of wall dampness, and can quickly drain water seeping under the floor tiles and water accumulating in the squat toilet area, preventing water from stagnating in the base layer and extending the service life of the waterproof layer.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A bathroom anti-seepage drainage structure includes a bathroom plan, a waterproof retaining wall at the front end of the top side of the bathroom plan, a waterproof guide wall at the middle of the top side of the bathroom plan, a stainless steel grating at the top side of the waterproof guide wall, a secondary drainage floor drain at the middle of the bottom side of the waterproof guide wall, a water trap at the bottom side of the bathroom plan, a concealed water pipe at the bottom side of the secondary drainage floor drain, the secondary drainage floor drain being connected to the water trap via the concealed water pipe, the bottom end of the concealed water pipe being fixedly connected to the top of the water trap, a structural beam slab fixedly connected to the top side of the bathroom plan, hollow blocks at the top side of the structural beam slab, a precast pressure beam at the top side of the hollow blocks, a reserved installation hole at the bottom side of the precast pressure beam, a water supply riser inside the installation hole, and a main water supply pipe fixedly connected to the top of the water supply riser.

[0008] Furthermore, the ground waterproof layer is made of cement-based penetrating crystallizing coating or polymer cement waterproof coating, with a thickness of 1.5mm, and the overlap width between the side of the ground waterproof layer and the wall waterproof layer is not less than 100mm.

[0009] Furthermore, the slope-finding layer is a polymer waterproof coating with a total thickness of 1.5 mm and a coating weight of approximately 2.5 kg / m². 2 The slope-finding layer has an additional waterproof layer reinforced with fiber cloth at the pipe root, floor drain, internal and external corners, and expansion joints. The width of the additional waterproof layer is 200mm wider than the perimeter of the weak parts.

[0010] Furthermore, the concealed water pipe is made of HDPE with a diameter of φ20, and the stainless steel grating has a hole diameter of ≤3mm.

[0011] Furthermore, the precast top beam is 150mm high and is located 200mm above the ceiling. The precast top beam is connected and fixed to the structural column by embedded steel plates or reinforcing bars.

[0012] Furthermore, the main water supply pipe is fixed to the bottom of the precast pressure beam by a saddle clamp, and the main water supply pipe is connected to the water supply riser by a tee or a cross.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figure 1 and Figure 2This utility model provides an embodiment of a bathroom anti-seepage drainage structure, including a bathroom plane 1, a waterproof retaining wall 6 at the front end of the top side of the bathroom plane 1, a waterproof guide wall 7 at the middle of the top side of the bathroom plane 1, a stainless steel grille 5 at the top side of the waterproof guide wall 7, a secondary drainage floor drain 8 at the middle of the bottom side of the waterproof guide wall 7, a water trap 10 at the bottom side of the bathroom plane 1, a concealed water pipe 9 at the bottom side of the secondary drainage floor drain 8, the secondary drainage floor drain 8 being connected to the water trap 10 through the concealed water pipe 9, the bottom end of the concealed water pipe 9 being fixedly connected to the top end of the water trap 10, a structural beam 2 being fixedly connected to the top side of the bathroom plane 1, hollow blocks being provided on the top side of the structural beam 2, a precast pressure top beam 3 being provided on the top side of the hollow blocks, a reserved installation hole being opened on the bottom side of the precast pressure top beam 3, a water supply riser 4 being provided inside the installation hole, and a water supply main pipe 11 being fixedly connected to the top end of the water supply riser 4.

[0020] Specifically, the structure is based on the structural beam slab 2 at the bottom of the bathroom floor plan 1. During construction, plywood backed with timber formwork is used for support, and fixed clamps and tie rods are used for reinforcement to ensure that the structural beam slab 2, the waterproof retaining wall 6, and the waterproof guide wall 7 are poured with concrete simultaneously. This integrated pouring method avoids structural cracks caused by the phased construction of components, reducing the risk of leakage from the source. The height of the waterproof retaining wall 6 is precisely matched to the finished height of the floor finish, effectively preventing water from the bathroom floor from overflowing into adjacent rooms. The waterproof guide wall 7 is 150mm high, forming a rigid anti-seepage barrier at the bottom of the wall, which can block the upward seepage of underground capillary water, laying the foundation for bathroom anti-seepage. A 1.5mm thick cement-based penetrating crystalline coating or polymer cement waterproof coating is applied to the top side of the waterproof guide wall 7 to form a ground waterproof layer 15. The side of the ground waterproof layer 15 overlaps with the wall waterproof layer by ≥100mm, creating a continuous seepage-proof interface without any breaks. The slope-forming layer 13 on the top side of the waterproof retaining wall 6 uses a polymer waterproof coating, and a 200mm wide fiber cloth reinforcement waterproof layer is added to vulnerable areas prone to leakage, such as pipe roots, floor drains, and internal and external corners, to enhance the seepage prevention capacity of key areas through localized reinforcement. At the same time, the moisture-proof layer 14 on the top side of the bathroom floor plan 1 works in conjunction with the ground waterproof layer 15 to further block moisture from penetrating into the walls or interior of the structure, providing double protection against seepage.

[0021] Reference Figure 3 and Figure 4 A waterproof guide wall 7 has a ground waterproof layer 15 on its top side, a slope-forming layer 13 on its top side, and a damp-proof layer 14 on its top side of the bathroom floor plan 1. The ground waterproof layer 15 uses cement-based penetrating crystalline coating or polymer cement waterproof coating, with a thickness of 1.5mm. The overlap width between the ground waterproof layer 15 and the wall waterproof layer is not less than 100mm. The slope-forming layer 13 is a polymer waterproof coating with a total thickness of 1.5mm and a coating weight of approximately 2.5kg / m². 2The slope-finding layer 13 has an additional waterproof layer reinforced with fiber cloth at pipe roots, floor drains, internal and external corners, and expansion joints. The width of the additional waterproof layer is 200mm wider than the perimeter of the weak points. The concealed water pipe 9 is made of HDPE with a diameter of φ20, and the stainless steel grating 5 has a hole diameter of ≤3mm. The precast pressure beam 3 is 150mm high and is set 200mm above the ceiling. The precast pressure beam 3 is connected and fixed to the structural column through embedded steel plates or steel bars. The main water supply pipe 11 is fixed to the bottom of the precast pressure beam 3 by saddle clamps 12. The main water supply pipe 11 is connected to the water supply riser 4 through a tee or cross. The structural beam slab 2 is reinforced with plywood backing and timber formwork, and reinforced with shaped clamps or tie rods. The waterproof curb 6 is made of tool-type corner molds or prefabricated square tubes. The concrete slump of the structural beam slab 2 and the waterproof curb 6 does not exceed 160mm.

[0022] Specifically, the stainless steel grille 5 installed on the top side of the waterproof guide wall 7 can intercept impurities in the water seeping from the gaps between the floor tiles, preventing impurities from clogging the drainage channel. The intercepted water falls through the stainless steel grille 5 into the secondary drainage floor drain 8 below, and then is directed to the water trap 10 through the concealed water pipe 9. The water seal height of the water trap 10 is ≥50mm, which not only meets the standard requirements for preventing odor backflow in drainage pipes, but also ensures smooth drainage of water, avoiding long-term stagnation of water under the floor tiles that could cause leakage or mold, and maintaining a dry environment in the bathroom. When laying hollow blocks, the hollow positions of the blocks are precisely aligned with the installation path of the water supply riser 4, reducing the need for later trenching damage to the wall structure for laying pipelines. When the wall is built to 200mm above the ceiling, a 150mm high precast pressure beam 3 is installed. The precast pressure beam 3 is connected and fixed to the structural column through embedded steel plates or steel bars to ensure that it has sufficient load-bearing capacity to support the pipeline load. Water supply riser 4 passes through the reserved installation hole of precast pressure beam 3, and its top end is connected to water supply main pipe 11 through tee or cross. Water supply main pipe 11 is fixed to the bottom of precast pressure beam 3 with saddle clamp 12 to ensure that the pipeline is installed firmly. After installation, micro-expansion waterproof mortar or foamed polyurethane is injected into the reserved hole to fully seal the gap between the pipe and the structure, prevent water vapor from seeping along the gap of the pipe, and achieve synergistic protection of pipeline installation and seepage prevention.

[0023] Working principle: The structural beam slab 2 on the bottom side of the bathroom floor plan 1 is reinforced with plywood backing timber formwork and fixed clamps for tie rod water-stopping. Concrete is poured simultaneously with the waterproof curb 6 and the waterproof guide wall 7 to prevent leakage caused by structural cracks. The height of the waterproof curb 6 is adapted to the finished floor finish, which can prevent water from the bathroom floor from overflowing into the outside room; the waterproof guide wall 7 is 150mm high, forming a rigid anti-seepage barrier at the bottom of the wall, blocking the upward seepage of ground capillary water.

[0024] A 1.5mm thick cement-based penetrating crystalline coating or polymer cement waterproof coating is applied to the top side of the waterproof guide wall 7 as the ground waterproof layer 15, with an overlap width of ≥100mm between its side and the wall waterproof layer to form a continuous seepage-proof interface. The slope-forming layer 13 on the top side of the waterproof retaining wall 6 uses a polymer waterproof coating, and a 200mm wide fiber cloth reinforcement waterproof layer is added at weak points such as pipe roots, floor drains, and internal and external corners to strengthen the seepage prevention capacity of easily leaking areas. At the same time, the moisture-proof layer 14 on the top side of the bathroom floor 1 works in conjunction with the ground waterproof layer 15 to further block moisture from penetrating into the walls or interior of the structure.

[0025] The stainless steel grille 5 on the top side of the waterproof guide wall 7 can intercept water seeping from the gaps in the floor tiles, preventing impurities from entering the drainage system. The water falls through the stainless steel grille 5 into the secondary drainage drain 8 below, and then is directed to the water trap 10 through the concealed water pipe 9. The water trap 10 has a water seal of ≥50mm, which can not only prevent the backflow of odors from the drainage pipe, but also ensure the smooth drainage of water, preventing long-term water retention under the floor tiles from causing leakage or mold.

[0026] When laying hollow blocks, ensure the hollow positions of the blocks correspond to the installation path of the water supply riser 4 to reduce damage to the wall structure during later grooving. When the wall is built 200mm above the ceiling, a 150mm high precast pressure beam 3 is installed, which is connected and fixed to the structural column via embedded steel plates or reinforcing bars to ensure stability under the load of the pipeline. The water supply riser 4 passes through the pre-drilled installation holes in the precast pressure beam 3, and its top end connects to the main water supply pipe 11 via a tee or cross. The main water supply pipe 11 is fixed to the bottom of the precast pressure beam 3 using saddle clamps 12. After installation, the pre-drilled holes are filled with micro-expansion waterproof mortar or polyurethane foam to seal the gaps between the pipe and the structure, preventing water vapor leakage along the pipe gaps.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
