Description

Technical Field

[0001] This utility model relates to the field of integrated bathroom technology, specifically to a layered waterproofing device for integrated bathrooms. Background Technology

[0002] A prefabricated bathroom is an integrated installation structure that includes the ceiling, floor, walls, and all bathroom fixtures. Unlike traditional bathrooms, prefabricated bathrooms are factory-made in one piece, making them compact, exquisite, and fully functional. They save bathroom space and are easier to clean.

[0003] The biggest pain point during bathroom installation, construction, and maintenance is the inadequacy of bathroom waterproofing technology. With the continuous innovation of new materials and technologies, integrated bathroom bases have emerged, reducing on-site construction joints. However, many processes still require manual completion, which inevitably leads to the risk of leakage. For example, the connection between the drain outlet of the bathroom base and the original drain location may have gaps, resulting in a loose connection and the potential for leakage along the pipe wall. In older residential areas, some basic drainage pipes are made of metal, which may leak after years of use.

[0004] For integrated bathrooms with a layered drainage structure, since the drainage pipes are already pre-installed, the location where the bathroom chassis connects with the pipes becomes a high-risk point. Preventing leakage of the pre-installed drainage pipes is a problem that needs to be solved during the application of integrated bathroom chassis.

[0005] Chinese patent CN115288488A discloses a multi-layered waterproofing method for integrated bathrooms in MIC modular buildings, as well as the integrated bathroom itself. The integrated bathroom includes a dry area and a wet area, each with a base. The waterproofing method first involves waterproofing the floor and wall seams to prevent water leakage. Secondly, a waterproof coating is applied to the wet area to prevent water leakage from the base. Then, floor mats are laid in the dry area to prevent water leakage from the base. These measures effectively prevent water leakage from the floor seams, wall seams, and base. Next, the base is installed and modified in the wet area to further reduce the possibility of water leakage. Finally, the drainage system is rebuilt, and the drainage pipes are modified to ensure smoother drainage and prevent water accumulation and sewage backflow.

[0006] The aforementioned waterproof structure achieves waterproofing of the bathroom by waterproofing the gaps. However, this method is only a temporary solution, and there is still leakage from the drainage pipes inside the wall. Over time, as the wall surface is sealed and the amount of water seeping into the wall gradually increases, there is a risk that the wall surface will bulge under pressure and the drainage pipes will burst under pressure. Utility Model Content

[0007] The present invention aims to overcome the defects in the prior art and provide a simple structured, pre-prevention integrated bathroom layered waterproofing device.

[0008] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a layered waterproof device for an integrated bathroom, comprising a drain pipe and a waterproof body for fitting the bottom of the drain pipe; the top of the waterproof body has an opening groove for fitting the drain pipe from bottom to top, and the waterproof body has a receiving cavity for accommodating the drain pipe; the top of the waterproof body has a top flange located on both sides of the opening groove, and a top fixing hole is formed on the top flange; the ends of the waterproof body have outwardly extending end flanges, and end fixing holes are formed on the end flanges; the waterproof body is equipped with a collection outlet for collecting liquid.

[0009] In a preferred embodiment of this utility model, the drainage pipe is suspended within the waterproof body, and there is a gap between the waterproof body and the drainage pipe.

[0010] In a preferred embodiment of this utility model, both the opening groove and the receiving cavity correspond to the length direction of the drain pipe.

[0012] As a preferred embodiment of the present invention, the bottom of the receiving cavity is formed with a slope, and the collection outlet is located at the lowest point of the slope.

[0013] As a preferred embodiment of this utility model, the waterproof body is composed of at least one straight part, and an angle transition piece is provided between the end of the straight part and the wall-mounted part to connect adjacent waterproof bodies.

[0014] As a preferred embodiment of this utility model, an angle adapter is provided between adjacent straight sections to connect the adjacent straight sections.

[0015] As a preferred embodiment of this utility model, the angle adapter includes an obtuse angle adapter and a right angle adapter.

[0017] As a preferred embodiment of this utility model, the straight-through component, the angle adapter, the multi-pass adapter, and the wall-mounted component all have top flanges, and the end flanges are formed on the wall-mounted component.

[0018] Compared with existing technologies, the design of the waterproof main structure using a drainage pipe allows the drainage pipe to be placed inside a receiving cavity.

Detailed Implementation

[0025] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] like Figures 1-5 As shown, a layered waterproofing device for an integrated bathroom includes a drain pipe 2 and a waterproof body 1 for fitting the bottom of the drain pipe 2. The top of the waterproof body 1 has an opening groove 16 for fitting the drain pipe 2 from bottom to top, and the waterproof body 1 has a receiving cavity 17 for accommodating the drain pipe 2. The top of the waterproof body 1 has top flanges 3 located on both sides of the opening groove 16, and top fixing holes 31 are formed on the top flanges 3. The ends of the waterproof body 1 have outwardly extending end flanges 4, and end fixing holes 41 are formed on the end flanges 4. The waterproof body 1 is equipped with a collection outlet 6 for collecting liquid.

[0027] Furthermore, the drain pipe 2 is pre-installed and connected to the bathroom base. The waterproof body 1 is designed according to the length of the drain pipe 2. With the action of the opening groove 16, the bottom of the drain pipe 2 can be connected by installing the waterproof body 1 from bottom to top. The receiving cavity 17 is used for pre-reserved collection of leaked liquid from the drain pipe 2.

[0028] The top flange 3 is used to increase the contact area between the top of the waterproof body 1 and the top surface. At the same time, expansion screws can be installed in the top fixing hole 31 to connect the waterproof body 1 to the top surface.

[0029] The end flange 4 is used to increase the contact area between the end of the waterproof body 1 and the wall surface, and expansion screws for connecting the waterproof body 1 and the wall surface can be installed in the end fixing hole 41.

[0030] With the help of the top flange 3 and the end flange 4, the waterproof body 1 can be connected to the wall and the top surface at the same time, thereby realizing the suspended installation of the waterproof body 1. The drainage pipe 2 is suspended inside the waterproof body 1, and there is a gap between the waterproof body 1 and the drainage pipe 2.

[0031] Since the drain pipe 2 is connected to the bathroom base, the drain pipe 2 is installed in an elevated manner under the support of the bathroom base. Therefore, the waterproof body 1 and the drain pipe 2 do not interfere with each other. The setting of the waterproof body 1 does not affect the stable setting of the drain pipe 2. At the same time, the gap between the waterproof body 1 and the drain pipe 2 allows the leaking water from the drain pipe 2 to fall into the waterproof body 1 and be collected.

[0032] Both the opening groove 16 and the receiving cavity 17 correspond to the length direction of the drain pipe 2. The dimensions of both the opening groove 16 and the receiving cavity 17 are larger than the dimensions of the drain pipe 2, thereby facilitating the connection of the drain pipe 2 within the waterproof body 1.

[0033] The top flange 3 and the end flange 4 are provided with a sealing layer 5. The sealing layer 5 can be foam or sealant. The sealing layer 5 is used to reduce storage error when the top flange 3 and the end flange 4 are in contact with the top surface or wall surface, and under the action of the sealing layer 5, it is used to prevent the odor of the drain pipe 2 from escaping.

[0034] The bottom of the receiving cavity 17 is sloped, and the collection outlet 6 is located at the lowest point of the slope, so that the leaked liquid can flow to the collection outlet 6 at the lowest point of the slope under the action of gravity, which facilitates the centralized treatment of the leaked liquid in the subsequent process.

[0035] The waterproof body 1 consists of at least one straight part 11. The end of the straight part 11 is connected to a wall-mounted part 15. The number and length of the straight parts 11 are designed according to the actual length and angle of the drainage pipe 2. The wall-mounted part 15 is located at the end of the waterproof body 1. Under the action of the wall-mounted part 15, the wall-mounted part 15 abuts against the wall, and the end flange 4 is connected to the wall.

[0036] An angle adapter is provided between adjacent straight sections 11 to connect them. The straight section 11 is a straight structure. The angle adapter is used to correspond to the bend of the drainage pipe 2. The angle adapter includes an obtuse angle adapter 12 and a right angle adapter 13.

[0037] At the connection between the angle adapter and the straight connector 11, a multi-way adapter 14 is also provided. The multi-way adapter 14 is used for the multi-way connector of the corresponding drainage pipe.

[0038] Top flanges 3 are formed on straight section 11, angle adapter, multi-pass adapter 14 and wall-mounted section 15, and end flanges 4 are formed on wall-mounted section 15.

[0039] In actual use, straight connectors 11 of different lengths, corresponding angle adapters and multi-port adapters 14 are selected according to the length and structure of the drain pipe 2 that is connected to the bathroom chassis. The straight connectors 11, corresponding angle adapters and multi-port adapters 14 are spliced ​​together by adhesive bonding, welding or hinges. Waterproofing measures are taken by applying waterproof glue during splicing.

[0040] By moving the assembled waterproof body 1 from bottom to top, the bottom of the waterproof body 1 is fitted onto the corresponding drainage pipe 2, and the waterproof body 1 fits over the entire bottom of the exposed drainage pipe 2. When the drainage pipe 2 does not leak, the installation of the waterproof body 1 does not affect the normal use of the drainage pipe 2. However, when the drainage pipe 2 leaks, the leaking liquid drips into the receiving cavity 17 of the waterproof body 1 and flows to the collection outlet 6 for collection under the action of the slope in the receiving cavity 17. This achieves the early collection and treatment of the leakage point, preventing the accumulation of leakage liquid in the wall and causing irreversible damage to the wall.

[0041] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention; therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.

[0042] Although this document frequently uses reference numerals from the accompanying drawings, such as: waterproof body 1, straight section 11, obtuse angle adapter 12, right angle adapter 13, multi-port adapter 14, wall-mounted section 15, opening groove 16, receiving cavity 17, drainage pipe 2, top flange 3, top fixing hole 31, end flange 4, end fixing hole 41, sealing layer 5, and collection outlet 6, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
