Abstract
Description
Technical Field
[0001] This utility model relates to the field of bathroom floor structure technology, specifically a bathroom floor structure that prevents water accumulation. Background Technology
[0002] Backfilling in sunken bathrooms is a crucial construction step, requiring adherence to specific procedures and standards to ensure a solid, level floor with excellent drainage. First, a waterproof coating is evenly applied inside the sunken area. Lightweight materials such as expanded clay or slag are then used for backfilling, followed by leveling with cement mortar and creating a drainage slope. A concrete layer is then laid, and finally, floor tiles are laid, with drains installed at the designated drainage points. However, this bathroom structure presents several potential water seepage risks. Firstly, the joint between the floor tiles and the drain cover can allow water to seep downwards if the waterproofing sealant fails, causing the filler layer to absorb excessive water and collapse. Secondly, the waterproofing layer is typically located at the bottom, meaning water seeping above it can only be absorbed through the filler layer. These issues necessitate improvement. Therefore, we propose a bathroom floor structure to prevent water accumulation. Utility Model Content
[0003] The purpose of this utility model is to provide a bathroom floor structure that prevents water accumulation, thus solving the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a bathroom floor structure for preventing water accumulation, comprising, from top to bottom, a floor tile layer, a filling layer A, a waterproof layer A, a filling layer B, and a waterproof layer B. A drain pipe is installed through the middle of the waterproof layer B. A floor drain pipe is fitted onto the top of the drain pipe. A floor drain cover is movably installed at the top of the floor drain pipe. An integral ring is formed on the outer circumference of the top of the floor drain pipe. Several drainage holes are opened around the outer circumference of the top of the floor drain pipe. A branch pipe is connected to the outer circumference of the bottom end of the floor drain pipe. A seepage cover is fitted onto the top of the branch pipe. The floor drain cover is flush with the floor tile layer. The top surface of the ring is in contact with the bottom surface of the floor tile layer.
[0005] Furthermore, the inner diameter of the ring cover is 40mm larger than the diameter of the drain cover.
[0006] Furthermore, the bottom of the ring cover is provided with a slope, and the drainage hole is flush with the bottom of the slope.
[0007] Furthermore, the top of the seepage cover is flush with the waterproof layer A.
[0008] Furthermore, the branch pipe is an inclined pipe, and the angle between the branch pipe and the drain pipe is set to 45°.
[0009] Furthermore, the waterproof layer A is level with the center of the drain pipe.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] 1. The technical solution of this application has a ring cover installed below the joint between the floor tile layer and the floor drain cover. Water seepage here will flow into the floor drain pipe through the slope and drainage hole, which prevents the filling layer from absorbing too much water and collapsing due to water seepage at the joint. The floor drain pipe adopts a large-diameter water flow channel to speed up the drainage rate and effectively prevent water accumulation on the bathroom floor.
[0012] 2. The technical solution of this application involves setting up a double waterproof layer on the bathroom floor. When water seeps into the surface tile layer, the water accumulates in the waterproof layer A. At this time, the accumulated water can flow from the seepage cover and branch pipe into the floor drain pipe, achieving the effect of secondary drainage. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0018] Example 1, as Figure 1-2 As shown, this utility model provides a technical solution: a bathroom floor structure to prevent water accumulation, comprising, from top to bottom, a floor tile layer 6, a filling layer A7, a waterproof layer A8, a filling layer B9, and a waterproof layer B10. A drain pipe 5 is installed through the middle of the waterproof layer B10. A floor drain pipe 1 is fitted on the top of the drain pipe 5. A floor drain cover 3 is movably installed on the top of the floor drain pipe 1. An annular cover 2 is integrally formed on the outer circumference of the top of the floor drain pipe 1. Several drainage holes 101 are opened around the outer circumference of the top of the floor drain pipe 1. A branch pipe 4 is connected to the outer circumference of the bottom end of the floor drain pipe 1. A seepage cover 401 is fitted on the top of the branch pipe 4. The floor drain cover 3 is flush with the floor tile layer 6. The top surface of the annular cover 2 is in contact with the bottom surface of the floor tile layer 6.
[0019] In a specific embodiment of this utility model, the construction steps of the bathroom floor structure are as follows: First, the bottom end of the drain pipe 1 is heat-fused to the drain pipe 5. The drain cover 3 at the top of the drain pipe 1 is removable and replaceable. The bottom layer of the bathroom floor structure is coated with a waterproof layer B10, followed by filling. The filling layer B9 can be a mixture of expanded clay and construction debris. The surface of the filling layer B9 is leveled and coated with a cement mortar layer, followed by a waterproof layer A8, making the waterproof layer A8 flush with the seepage cover 401. A drainage slope is made around the seepage cover 401 to facilitate the flow of accumulated water to the seepage cover 401. The surface of the seepage cover 401 is provided with multiple 0.8mm fine holes. Then, the filling layer A7 is laid. The surface of the filling layer A7 is leveled and coated with a cement mortar layer. Finally, the floor tile layer 6 is laid. The floor tile layer 6 has through holes with the same dimensions as the drain cover 3. The top surface of the ring cover 2 is attached to the bottom surface of the floor tile layer 6. The joint between the floor tile layer 6 and the drain cover 3 is treated with a sealant.
[0020] In the preferred technical solution, the inner diameter of the ring cover 2 is 40mm larger than the diameter of the drain cover 3. The ring cover 2 is used to guide the water seeping down from the joint between the floor tile layer 6 and the drain cover 3.
[0021] In the preferred technical solution, the bottom end of the ring cover 2 is provided with a slope 201, and the drainage hole 101 is flush with the bottom of the slope 201. The slope 201 is conducive to drainage, so that the seepage water flows into the drainage hole 101 quickly.
[0022] In the preferred technical solution, the top of the seepage cover 401 is flush with the waterproof layer A8. When the surface tile layer 6 seeps water, the water accumulates in the waterproof layer A8. The waterproof layer A8 is flush with the center height of the drain pipe 1. At this time, the accumulated water can flow from the seepage cover 401 and the branch pipe 4 into the drain pipe 1, achieving the effect of secondary drainage.
[0023] In the preferred technical solution, the branch pipe 4 is an inclined pipe, and the angle between the branch pipe 4 and the drain pipe 1 is set to 45°. The inclined pipe is more conducive to guiding the accumulated water to drain into the drain pipe 1 quickly.
[0024] Working principle: Under normal circumstances, water on the bathroom floor flows from the drain cover 3 into the drain pipe 1 and is eventually drained away through the drain pipe 5. When water seeps at the joint between the floor tile layer 6 and the drain cover 3, the seeping water passes through the ring cover 2, the slope 201, and the drain hole 101, and finally flows into the drain pipe 1. When water seeps into the floor tile layer 6, the water is first absorbed by the filling layer A7. When the absorption is saturated, the water passes through the seepage cover 401 and the branch pipe 4, and finally flows into the drain pipe 1, achieving the effect of secondary drainage.
