Detachable flexible water-proof casing pipe device

Abstract

The invention discloses a detachable flexible water-proof casing pipe device which comprises an inner pipe, an upper flange, a lower flange, a water-proof rubber ring, a sealing casing pipe, a wall body, a flange with inner threads, a lower end flange and a rubber ring, wherein the inner pipe and the lower end flange are in threaded connection; the lower end flange and the flange with the inner threads are connected through a screw; the flange with the inner threads is connected with the sealing casing pipe; the sealing casing pipe is filled with a macromolecular filler; the lower flange is fixedly connected with the sealing casing pipe; the lower flange and the upper flange are connected through a screw; threads are formed at the lower end of the inner pipe; threads matched with the inner pipe are formed in the center hole of the lower end flange. The detachable flexible water-proof casing pipe device has the advantages of being simple in structure, easy to manufacture, low in cost, strong in practicability, safe and reliable, and having effective water resistance, shock resistance and sound insulation property and capable of reducing the construction cost.

Description

technical field [0001] The invention relates to a waterproof device for building pipelines, more specifically, to a detachable flexible waterproof sleeve device for penetrating through and communicating with two ends of a wall. Background technique [0002] At present, in the construction of construction projects, wall-through sleeves are pre-embedded at the perforations of concrete slabs or walls, and are used for various pipelines to pass through buildings. The pre-embedded pipe generally has only one straight pipe fitting, and there are often some damages at the perforation, resulting in an unsightly wall. Most of the existing wall-through casings only use screws to fix the flange so that the pipe body is fixed, but the pipe The stability of body fixing is not strong, it is easy to loosen, and leakage often occurs, which affects the use. Between the embedded casing and the pipe passing through it, there is little filler or the filler is mostly rigid material and cannot c...

AI Technical Summary

Problems solved by technology

The pre-embedded pipe generally has only one straight pipe fitting, and there are often some damages at the perforation, resulting in an unsightly wall. Most of the existing wall-through casings only use screws to fix the flange so that the pipe body is fixed, but the pipe The stability of body fixing is not strong, it is easy to loosen, and leakage often occurs, which affects the use

Between the cast-in casing and the pipe passing through it, there is little filler or the filler is mostly rigid material and does not completely fill the void

Therefore, the traditional casing and its waterproof method cannot better meet the waterproof requirements of the perforation. When the waterproof service period is exceeded, it is easy to cause water leakage, and it cannot play a good role in earthquake resistance and noise reduction.

When the inner tube of the building casing body is damaged or needs to be replaced, the traditional casing makes it difficult to disassemble the pipe
