Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of waterproof pipes, and relates to a plastic pipe structure with a waterproof function, in particular to a building waterproof product used for plastic pipes in buildings to pass through waterproof layers. Background Art
[0002] Waterproofing in buildings is a problem that people will inevitably encounter in their daily lives. There are many locations for building waterproofing, such as kitchens, bathrooms, balconies, etc. At the same time, people's domestic water is also inseparable from plastic pipes. PPR plastic pipes are used for water supply, and PVC or HDPE pipes are used for drainage. When using plastic pipes, it is inevitable that the plastic pipes pass through the waterproof layer. At present, there are many ways to waterproof plastic pipes passing through the waterproof layer, including pre-buried water stop joints, pre-buried steel casings, and even directly using plastic pipes to pass through the floor slab. The usual method of waterproofing this place is to wet-bond the waterproof layer material (steel casing, plastic pipe fittings) and the waterproof layer, and then apply sealant. This method is very easy to cause leakage due to poor construction technology and other reasons. Utility Model Content
[0003] In view of the above-mentioned problems, the utility model provides a plastic pipe structure with waterproof function, which solves the technical problem that when the pipe passes through the waterproof layer, water leakage easily occurs in the traditional process.
[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0005] A plastic pipe structure with waterproof function, including a pipe body, a first support ring and a second support ring distributed up and down are arranged on the outside of the pipe body, a waterproof cloth is fixed on the first support ring, the waterproof cloth is overlapped and fixed with a waterproof layer, and the main body of the pipe body is embedded in a concrete floor and limited by the second support ring.
[0006] As a further technical solution, the first support ring and the second support ring are both arranged vertically to the pipe body, and the first support ring and the second support ring have the same size.
[0007] As a further technical solution, the radial width of the first support ring is smaller than the radial width of the waterproof cloth.
[0008] As a further technical solution, there is a certain overlapping area between the waterproof layer and the waterproof cloth, which are sealed and connected by a wet method or other process.
[0009] As a further technical solution, the waterproof layer is then pasted with ceramic tiles after being slurried with cement.
[0010] The technical solution of the utility model is to add a transition piece (waterproof cloth) when the pipeline passes through the waterproof layer, so that there is a sealed transition between the pipeline and the waterproof layer, and the plastic pipe fittings and the waterproof cloth are reliably connected through a low-pressure injection molding process to form an integral product, which appears on site as a finished product, and converts the waterproof problem of the pipeline passing through the waterproof layer into a problem of sealed connection between waterproof materials and waterproof materials, thereby solving the problem of water leakage easily occurring when the traditional pipeline passes through the waterproof layer.
[0011] The technical solution of the utility model has the following beneficial effects:
[0012] The first support ring and the waterproof cloth of the utility model are connected by a low-pressure injection molding process, which is very firm and achieves a completely reliable connection, ensuring that water does not flow between the plastic and the waterproof cloth;
[0013] The plastic pipe fitting of the utility model is cast and fixed in the concrete floor slab, and the second support ring plays a supporting and limiting role, which can limit the upward and downward movement of the pipe fitting and increase the firmness of the installation;
[0014] The utility model waterproof cloth is a flexible material, and the surface is a fibrous material, so the waterproof layer and the waterproof cloth can be safely overlapped, and the waterproof cloth is also a flexible material, and is not afraid of the tiny gaps caused by the deformation between the pipe and the concrete.

[0017] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.
[0018] like Figure 1 As shown, the utility model is a plastic pipe structure with waterproof function, which is mainly aimed at improving the installation structure of the existing pipeline when passing through the waterproof layer, so as to solve the problem of easy leakage when the traditional pipe and the waterproof layer are sealed. The structure is as follows:
[0019] A plastic pipe structure with waterproof function, comprising a pipe body 1, a first support ring 2 and a second support ring 3 are arranged on the outer side of the pipe body 1, and a waterproof cloth 4 is fixedly arranged on the first support ring 2. The waterproof cloth 4 is overlapped and fixed with a later waterproof layer 5. There is a certain overlap area between the later waterproof layer 5 and the waterproof cloth 4, and they are fixedly connected by gluing. The lower end of the pipe body 1 is embedded in a concrete floor 6 and is limited by the second support ring 3.
[0020] Preferably, the first support ring 2 and the second support ring 3 are both arranged perpendicular to the pipe body 1 , and the first support ring 2 and the second support ring 3 have the same size. The radial width of the first support ring 2 is smaller than the radial width of the waterproof cloth 4 .
[0021] The waterproof layer 5 is then slurried with cement and then adhered with tiles 7.
[0022] The utility model mainly adds a transition piece (waterproof cloth) when the pipeline passes through the waterproof layer, so that there is a sealed transition between the pipeline and the waterproof layer 5 made later, and reliably connects the plastic pipe fittings and the waterproof cloth 4 through a low-pressure injection molding process to form an integral product, which appears on site in the form of a finished product, and converts the waterproof problem of the pipeline passing through the waterproof layer into a problem of sealed connection between waterproof materials and waterproof materials, thereby solving the problem of easy leakage of traditional pipelines passing through waterproof layers.
[0023] The specific process of connecting the plastic pipe fittings and the waterproof cloth is as follows: first make a pipe fitting mold according to the pipe fitting structure, fit the waterproof cloth 4 on the mold, close the mold, and prepare for injection molding through mechanical equipment. First, heat and melt the plastic particles to form a fluid, and squeeze the fluid slurry into the mold through the injection molding screw. After cooling, the plastic pipe fittings and the waterproof cloth 4 form a whole product.
[0024] After the plastic pipe and the waterproof cloth 4 form a whole product, the whole product is installed and fixed through the waterproof layer. Specifically, a hole for installation is reserved first, and the plastic pipe with the waterproof cloth 4 is placed in the hole for installation, and then concrete is poured around the hole to form a solid whole. The second support ring 3 plays the role of limiting support to increase the firmness of the installation. When the concrete is poured to the position of the first support ring 2, the pouring is stopped, and after solidification, the waterproof layer 5 is laid. The waterproof layer 5 is generally made of coatings, transfer materials, etc. through wet processes to form an overlapped fixed connection with the waterproof cloth 4, for example, by uniform scraping. After the waterproof layer 5 is completed, cement is slurried on it, and finally the top tiles 7 are laid.
[0025] The utility model has the following beneficial effects:
[0026] The first support ring 2 and the waterproof cloth 4 of the utility model are connected by a low-pressure injection molding process, which is very firm and completely sealed;
[0027] The plastic pipe fitting of the utility model is cast and fixed in the concrete floor slab, and the second support ring 3 plays a supporting and limiting role, which can limit the upward and downward movement of the pipe fitting and increase the firmness of the installation;
[0028] The waterproof cloth 4 of the utility model is a flexible material, and the surface is a fibrous material, so the waterproof layer 6 and the waterproof cloth 4 can be safely overlapped. At the same time, the waterproof cloth 4 is also a flexible material and is not afraid of the tiny gaps caused by the deformation between the pipeline and the concrete.
[0029] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
