Description

Technical Field

[0001] The present application relates to the field of bathroom waterproofing technology, and in particular to a bathroom waterproofing structure and construction method. Background Art

[0002] Bathrooms often have showers. When separating wet and dry areas, the shower room is measured and a water barrier is installed on the floor. The barrier is made of aluminum alloy or ceramic tile and adhered to the bathroom floor tiles with silicone sealant. However, prolonged contact with water can accelerate the aging of the silicone sealant, leading to water seepage and leakage. When the silicone sealant fails, water from the shower room leaks outward while the user is bathing, causing water to accumulate on the floor outside the shower room, making it difficult to clean. Summary of the Invention

[0003] In order to improve the waterproof effect between the shower room and other areas of the bathroom, the present application provides a bathroom waterproof structure and construction method.

[0004] The present application provides a bathroom waterproof structure that adopts the following technical solutions:

[0005] A waterproof structure for a bathroom includes a water collection pool for receiving water flow from a shower room, a trough is provided at the bottom of the shower room, the water collection pool is fixed in the trough, a drain pipe is provided on the bottom wall of the trough, a drain outlet for communicating with the drain pipe is provided at the bottom of the water collection pool, the side walls of the water collection pool extend upward and out of the trough, and a support and filtering assembly for a user to stand is provided in the water collection pool.

[0006] By adopting the above technical solution, a trough is set on the ground corresponding to the shower room, and a water collection pool is installed in the trough. The water in the shower room is collected by the water collection pool, and the filter assembly is supported for the user to stand and filter the water in the shower room to reduce the blockage of the drain pipe. The side wall of the water collection pool extends upward and out of the trough, which can reduce the water in the water collection pool from flowing out of the shower room, thereby helping to improve the waterproof effect of the bathroom.

[0007] Optionally, the support and filtration assembly includes a support frame arranged in the water collection pool, a boss for supporting the support frame is provided on the inner wall of the water collection pool, and a permeable plate is mounted on the support frame.

[0008] By adopting the above technical solution, the operator installs a support frame in the water collection pool, and forms a support table for supporting the user by installing a permeable board on the support frame. In addition, the permeable performance of the permeable board can achieve the effect of draining water from the water collection pool, and the permeable board can also have a good filtering effect, which can reduce the situation where debris enters the water collection pool and causes drainage blockage.

[0009] Optionally, the support frame is provided with a plurality of through installation grooves, the permeable plates are provided in multiple and correspond one to one with the installation grooves, the permeable plates are fixedly connected in the corresponding installation grooves, and the permeable plates are detachably provided on the support frame through a fixing unit.

[0010] By adopting the above technical solution, a number of permeable plates are provided, and the permeable plates can be detachably arranged on the support frame through the fixing assembly, which makes it convenient for the operator to replace the permeable plates. It is also convenient for the operator to disassemble the permeable plates to repair and maintain the water collection pool.

[0011] Optionally, the fixing unit includes a plurality of studs, the support frame is provided with screw holes penetrating the support frame, the studs are threadedly connected to the screw holes, and a pressure plate for pressing the permeable plate is fixedly connected to the studs.

[0012] By adopting the above technical solution, the operator installs the permeable board in the corresponding installation groove, and then threads the studs in each threaded hole so that the pressure plate on the stud is pressed tightly against the permeable board, thereby achieving the effect of detachable fixation of the permeable board on the support frame.

[0013] Optionally, a water hole is formed through the stud, a mounting groove connected to the water hole is formed at the top of the stud, a filter plate for covering the water hole is provided in the mounting groove, and the filter plate is fixedly connected to the stud via a connecting unit.

[0014] By adopting the above technical solution, water-permeable holes are set on the studs, which is conducive to accelerating the discharge of water above the water-permeable plate toward the water collection pool, and is conducive to improving the drainage effect. The operator sets a filter plate on the studs to cover the water-permeable holes, thereby reducing the problem of debris entering the water collection pool through the water-permeable holes and causing blockage of the drain pipe.

[0015] Optionally, the connecting unit includes a limit block fixedly connected to the mounting groove, a gap is left between the limit block and the bottom wall of the mounting groove for the filter plate to rotate, the filter plate is provided with an embedding groove for accommodating the limit block, and a through hole for the limit block to pass through, and a spring is provided in the mounting groove for pushing the filter plate away from the mounting groove.

[0016] By adopting the above technical solution, when the operator installs the filter plate, the spring is placed in the installation groove, and then the filter plate is placed in the installation groove. The through hole of the filter plate is aligned with the limit block. Then the operator presses the filter plate to make the filter plate move toward the installation groove. During this process, the limit block passes through the through hole. Finally, the operator rotates the filter plate to align the embedded groove on the filter plate with the limit block. The operator releases the pressing effect on the filter plate, the spring resets, and presses the filter plate tightly against the limit block. At this time, the limit block and the embedded groove cooperate with each other to limit the filter plate from rotating at will, so that the filter plate can be detachably fixed in the installation hole.

[0017] Optionally, a sleeve is fixedly connected to one end of the filter plate facing the water permeable hole, the sleeve can be inserted into the through hole, the spring is sleeved on the sleeve, a support rod is fixedly connected to the outer wall of the sleeve, and the support rod is inserted into the spring.

[0018] By adopting the above technical solution, a sleeve is provided to guide the spring, a support rod is provided on the outer wall of the sleeve, and the support rod is inserted into the spring to fix the spring, thereby reducing the situation where the spring pops out and is lost when the operator disassembles the filter plate.

[0019] Optionally, a notch is provided on the stud and is connected to the water permeable hole. An elastic sheet is fixedly connected to the notch. A ratchet is fixedly connected to the elastic sheet. The support frame is provided with an annular groove at the upper end of the screw hole. An internal-toothed ratchet is fixedly connected to the annular groove. The ratchet is engaged with the internal-toothed ratchet under the elastic force of the elastic sheet. The ratchet cooperates with the internal-toothed ratchet to limit the reverse rotation of the stud and cause loosening.

[0020] By adopting the above technical solution, the ratchet teeth are inserted into the internal ratchet wheel under the elastic force of the elastic plate, and the operator can only rotate the stud to tighten the stud into the threaded hole, and the stud is restricted from rotating in the opposite direction, thereby reducing the possibility of stud rotation. If the stud needs to be removed, the operator can move the elastic plate to disengage the ratchet teeth from the internal ratchet wheel, thereby releasing the restriction on the stud's rotation direction and facilitating the operator to rotate the stud out of the threaded hole.

[0021] Optionally, an overflow port is provided on the side wall of the water collecting pool near the top, a filter screen is detachably provided in the overflow port, an overflow pipe is connected to the overflow port, and the overflow pipe extends into the water collecting pool and is connected to the water collecting pool.

[0022] By adopting the above technical solution, when the drainage speed of the permeable plate and the permeable hole is too slow and the water level in the shower room is too high, if the water level reaches the overflow port position, it will be discharged toward the overflow pipe to reduce the situation where the water level is too high and overflows outside the shower room.

[0023] This application also provides a bathroom waterproofing construction method using the following technical solutions:

[0024] A bathroom waterproofing construction method comprises the following steps:

[0025] S1: Dig a trough at the location of the bathroom corresponding to the shower room, and clean the floor and walls; S2: Clean the roots of the upper and lower water pipes and perform leak-proofing treatment; S3: Apply waterproof emulsion; S4: Adhere waterproof membrane; S5: Apply waterproof cement and perform roughening process; S6: Repeat steps S and S; S7: Apply waterproof cement on the inner wall of the trough and the outer wall of the water collection pool, and install the water collection pool in the trough; S8: Apply multiple layers of waterproof emulsion between the drain outlet of the water collection pool and the drain pipe in the trough; In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. Install a water collection tank in the trough. The side walls of the water collection tank extend upward and out of the trough. Compared with directly bonding water barriers to the ground, this can reduce the water in the water collection tank from flowing out of the shower room, thereby helping to improve the waterproof effect of the bathroom.

[0027] 2. Multiple permeable panels are detachably mounted on the support frame, making it easy for the operator to replace the panels or perform repairs and maintenance on the water collection tank;

[0028] 3. Set up an overflow outlet. When the drainage speed of the permeable board and the permeable hole is too slow and the water level in the guide column shower room is too high, drain the water through the overflow outlet to reduce the situation where the water level is too high and overflows outside the shower room.

[0038] The following is combined with Figure 1-8 This application is described in further detail.

[0039] The present application embodiment discloses a bathroom waterproof structure. Figure 1 and Figure 2 The bathroom waterproof structure includes a rectangular water collection pool 1. A sink 11 for accommodating the water collection pool 1 is provided on the floor of the corresponding shower room. The water collection pool 1 is installed in the sink 11 and is fixed to the sink 11 by bonding with waterproof material. A drain pipe 12 is provided on the bottom wall of the sink 11.

[0040] like Figure 3 and Figure 4 The bottom wall of the water collection tank 1 is provided with a drain port 13 for communicating with a drain pipe 12. The bottom wall of the water collection tank 1 is inclined downward near the drain port 13. The side walls of the water collection tank 1 extend upward and extend out of the trough 11. The side walls of the water collection tank 1 are higher than the floor of the toilet to form an enclosure.

[0041] A support filter assembly 2 for supporting the user is provided within the water collection tank 1. The support filter assembly 2 comprises a circle of bosses 21 fixedly connected to the inner wall of the water collection tank 1. A support frame 22 is mounted on the bosses 21 and is removably fixed to the bosses 21 via bolts. The support frame 22 is provided with a plurality of vertical through slots 23. In the embodiment of the present application, the plurality of through slots 23 are arranged in a 3×3 matrix. A frame-shaped support surface 24 is fixedly connected to each through slot 23. A permeable plate 25 is installed within the through slot 23 and mounted on the support surface 24.

[0042] like Figure 4 and Figure 5The support frame 22 is provided with a fixing unit 3 for fixing the permeable plate 25. The fixing unit 3 includes a plurality of studs 31. The support frame 22 is provided with screw holes 32 between every four adjacent permeable plates 25. The studs correspond to the studs 31 one by one, and each stud 31 is threadedly connected to the corresponding screw hole 32. A pressure plate 33 is fixedly connected to the stud 31. When the pressure plate 33 is pressed tightly on the permeable plate 25, the permeable plate 25 is fixed.

[0043] The stud 31 has a circular water hole 4 coaxially defined along its axis. A circular mounting groove 41 is defined at one end of the stud 31, near the pressure plate 33. The mounting groove 41 is coaxially connected to and connected to the water hole 4, and the diameter of the mounting groove 41 is larger than that of the water hole 4. A circular filter plate 42 is removably disposed within the mounting groove 41, which filters water entering the water hole 4. The water-permeable plate 25 is removably mounted within the mounting groove 41 via a connecting unit 5.

[0044] like Figure 5 and Figure 6 The connection unit 5 includes a plurality of stoppers 51 fixedly connected to the inner sidewall of the mounting groove 41. The stoppers 51 are evenly distributed along the circumference of the mounting groove 41, and a gap is left between each stopper 51 and the bottom wall of the mounting groove 41 for accommodating the filter plate 42. Through holes 52 are formed on the circumferential wall of the filter plate 42 at the positions corresponding to each stopper 51, for receiving the stopper 51. A recess 53 for accommodating the stopper 51 is provided on one side of the filter plate 42 between adjacent through holes 52. The recesses 53 are evenly distributed along the circumference of the filter plate 42. A sleeve 6 is coaxially fixedly connected to the side of the filter plate 42 facing away from the embedding groove 53. The sleeve 6 is used to be inserted into the water permeable hole 4. A spring 61 is sleeved on the outer wall of the sleeve 6. A limiting groove 63 for accommodating the spring 61 is coaxially provided on the bottom wall of the mounting groove 41. The spring 61 abuts against the bottom wall of the limiting groove 63. A plurality of support rods 62 are fixedly connected to the outer peripheral wall of the sleeve 6 close to the filter plate 42. The axial direction of the support rod 62 is parallel to the radial direction of the sleeve 6. The support rod 62 is inserted into the spring 61 to achieve a fixing effect on the spring 61.

[0045] When installing the filter plate 42, the operator inserts the sleeve 6 into the water permeable hole 4, then presses the filter plate 42, causing the filter plate 42 to overcome the elastic force of the spring 61 and move toward the installation slot 41. During the pressing process, the operator adjusts the position of the filter plate 42 so that the through-hole 52 is aligned with the stop block 51, allowing the stop block 51 to pass through the corresponding through-hole 52. When the filter plate 42 moves between the stop block 51 and the bottom wall of the installation slot 41, the operator rotates the filter plate 42 so that the locking groove 53 is aligned with the corresponding stop block 51. Finally, the operator releases the filter plate 42, causing the filter plate 42 to move away from the bottom wall of the installation slot 41 under the elastic force of the spring 61 until the stop block 51 engages with the locking groove 53, thereby fixing the filter plate 42 in a removable position within the installation slot 41. The fact that the rotation of the filter plate 42 is restricted by the locking groove 53 helps to improve the installation stability of the filter plate 42 within the installation slot 41.

[0046] like Figure 7 and Figure 8 The support frame 22 is provided with an annular groove 7 coaxially near the upper end of the screw hole 32, and an internal tooth ratchet 71 is fixedly connected coaxially in the annular groove 7.

[0047] like Figure 5 and Figure 8 The side wall of the stud 31 is provided with a notch 74 that communicates with the water-permeable hole 4. An elastic piece 72 is fixedly connected to the stud 31 at the location of the notch 74. A ratchet 73 is fixedly connected to the elastic piece 72. Under the elastic force of the elastic piece 72, the ratchet 73 rotates toward the internally toothed ratchet 71 and engages with the internally toothed ratchet 71. At this point, the stud 31 can only rotate in the tightening direction and is restricted from rotating in the opposite direction, which helps to improve the installation stability of the stud 31 in the screw hole 32. To loosen the stud 31, the operator needs to move the elastic piece 72 to disengage the ratchet 73 from the internally toothed ratchet 71, allowing the operator to remove the stud 31.

[0048] An overflow outlet 14 is provided on the side wall of the water collecting tank 1 near the top, and a filter screen 15 is detachably fixedly connected to the overflow outlet 14. An overflow pipe 16 for communicating with the overflow outlet 14 is fixedly connected to the outside of the water collecting tank 1. The overflow pipe 16 extends downward into the water collecting tank 1 and is used to accelerate drainage and reduce water outflow from the shower room when the water permeable hole 4 is blocked, resulting in slow drainage and excessively high water level in the shower room.

[0049] The implementation principle of the embodiment of the present application is: by setting a water collection pool 1 in the shower room, the water in the shower room is collected by the water collection pool 1 and discharged. Compared with the traditional waterproofing by directly gluing water barriers on the bathroom floor, the one-piece water collection pool 1 in the present application has a better waterproof effect and is less likely to cause water to leak out of the shower room.

[0050] The present application also discloses a bathroom waterproofing construction method, which comprises the following steps:

[0051] S1: Set a sink 11 at the shower room location in the bathroom. The operator can use an electric pickaxe to dig or raise the ground around the shower room, or a combination of digging and raising to form the sink 11 at the shower room location, and arrange drainage pipes 12 in the sink 11. After completing the installation of the sink 11 and the arrangement of the pipes in the sink 11, the operator needs to clean the floor and walls to prepare for the subsequent application of waterproof material.

[0052] S2: Clean and seal all water pipes to prevent blockage and drainage difficulties.

[0053] S3: Apply waterproof emulsion on the cleaned walls, floors and each wall of the sink 11, and let it stand to solidify;

[0054] S4: Attach waterproof membrane to the painted floor, groove walls and walls 1.5m from bottom to top;

[0055] S5: Apply waterproof cement on the waterproof membrane and roughen it

[0056] S6: Repeat the steps of S3 and S5, repeatedly applying the waterproof emulsion and waterproof cement;

[0057] S7: Apply waterproof cement on the inner wall of the sink 11 and the outer wall of the water collection pool 1, and install the water collection pool 1 in the sink 11. Let it stand for the waterproof cement to solidify so that the water collection pool 1 is consolidated in the sink 11. Apply multiple layers of waterproof emulsion between the drain outlet 13 of the water collection pool 1 and the drain pipe 12 in the sink 11 to reduce water seepage and leakage at the connection between the drain outlet 13 and the drain pipe 12;

[0058] S8: Install a support filter assembly 2 in the water collection pool 1 to support the user in bathing in the shower room.

[0059] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
