Description

A pipeline waterproofing device extending out of the roof

technical field

The utility model relates to the technical field of pipeline waterproofing, in particular to a pipeline waterproofing device extending out of a roof.

Background technique

At present, the use of pipelines is becoming more and more common, and it plays an important role in both production and life. Pipeline is a device used to transport gas, liquid or fluid with solid particles, which is connected by pipes, pipe connectors and valves. It is mainly used in the fields of water supply, drainage, heating, agricultural irrigation, hydraulic engineering and gas transmission. . In the process of transporting the medium, the pipeline will often enter from the outside into the room or extend from the room to the outside through obstructions such as walls or planks. At this time, the outdoor pipeline part needs to face a very critical problem, that is, the waterproofing of the pipeline. The problem is particularly important in rainy cities such as the south. In particular, the pipes extending out of the roof are waterproof. Since the pipes and the roof openings are generally facing the direction of rain, the rainwater can easily penetrate into the roof structure through the connection between the roof openings and the pipes, resulting in damage to the roof structure and indoor Water seepage and other situations that affect production and life occur, so the waterproofing of pipes extending out of the roof is particularly critical.

The existing Chinese utility model patent with the publication number CN208604849U discloses a pipeline waterproofing device extending out of the roof. The lower end is sleeved with a casing, the outer wall of the pipe and the inner wall of the casing are filled with mortar, the top and the root of the joint between the casing and the pipe are provided with sealing paste, and the pipe is The outer wall is also provided with a waterproofing membrane, and the waterproofing membrane is sleeved on the pipe, the waterproofing membrane extends toward the interior of the roof structure along the length direction of the pipeline, and the mortar is located in the waterproofing between the coil and the inner wall of the sleeve. The utility model effectively solves the problem of leakage at the root of the pipeline, and effectively improves the ability of the pipeline to prevent water seepage at the root.

The prior art scheme in the above has the following defects: when the device is installed, it needs to go through the process of pouring concrete, chiseling and smoothing the reserved hole, compacting fine stone concrete, setting a waterproof coating layer, setting an additional layer of waterproof coiled material, and setting a thermal insulation layer. After a series of processes, the device is integrated with the pipeline after installation. After the pipeline is used for a long time, the pipeline will be damaged and needs to be repaired and replaced. The waterproof device needs to be destroyed before repair or replacement. After repair or replacement It is necessary to go through a relatively cumbersome process to install the waterproof device again, and the waterproof device to be installed again is inconvenient to use because of its complicated structure.

Utility model content

Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a pipeline waterproofing device extending out of the roof, which has the effects of simple structure, convenient disassembly and use while ensuring good waterproofness.

The above-mentioned utility model purpose of the present utility model is achieved through the following technical solutions:

A pipeline waterproofing device protruding from a roof, comprising a pipeline protruding from the roof and a sleeve sleeved outside the pipeline, the sleeve comprising a first sleeve and a second sleeve arranged in a reserved hole of the pipeline, the The first sleeve is located below the second sleeve, the first sleeve extends into the roof, an end of the first sleeve close to the second sleeve is provided with a first flange, and the second sleeve is One end close to the first sleeve is provided with a second flange, the lower surface of the first flange is fixedly connected to the upper surface of the roof, the second flange and the first flange are fitted and arranged, and the second flange It is bolted to the first flange.

By adopting the above technical solution, when installing, first clean and level the surface of the reserved hole in the pipeline, clean and level the side wall of the hole, and then place the first sleeve into the reserved hole to ensure that the first flange is under the The surface is attached to the upper surface of the reserved hole, and the next step is to pour concrete on the outside of the first flange, so that the concrete is connected to the outer circumferential surface of the first flange, that is, the second sleeve is fixedly connected to the surface of the roof, and the bolts are tightened to make the first flange. An extrusion is formed between a flange and a second flange; when the pipeline in the reserved hole of the pipeline is damaged or needs to be replaced due to aging, by unscrewing the bolt between the second flange and the first flange, The pipeline device can be easily disassembled. In conclusion, the device has a certain waterproof ability, and is very convenient for installation, maintenance and maintenance, and realizes the effect of convenient use.

In a preferred example of the present invention, a leveling layer laid with mortar is further provided between the first flange and the roof structure, and a leveling layer is provided between the leveling layer and the lower surface of the first flange Waterproof paint.

There is a waterproof sealing layer 13. On the one hand, when the protective shell 10 is tightened around the second sleeve 32, the tightening part gives the waterproof gasket 9 a pressure towards the pipe 2 from the side, so that the waterproof gasket 9 and the pipe 2 are connected. On the other hand, the protective shell 10 also acts as a waterproof part, which to a certain extent isolates the second casing 32 from contact with the outside rainwater, extending the second casing 32 During use, the protective shell 10 can be easily replaced and maintained, which is convenient for use, and rainwater can fall along the inclined surface 14 as soon as possible to avoid excessive accumulation of rainwater and lead to leakage to the threaded connection.

1 and 2, the inner diameter of the bottom of the protective shell 10 is larger than the outer diameter of the first flange 311, the lower surface of the protective shell 10 is provided with a first annular groove 11, and the first annular groove 11 is provided with a first waterproof gasket 12.
