Description

Technical Field

[0001] The utility model belongs to the technical field of wall-piercing technology, and particularly relates to a waterproof component for a building wall-piercing pipe. Background Technique

[0002] During the construction of a house, it is often necessary to set up wall-piercing pipes for ventilation and drainage in future life. In order to prevent water from entering the house through the gap between the wall-piercing pipe and the wall, a casing and hemp yarn grease are used for sealing. After the casing is installed in the wall, usually the gap between the casing and the wall-piercing pipe is sealed with hemp yarn grease. However, there is still a probability of leakage in this way. Therefore, we designed a waterproof component for a building wall-piercing pipe. After sealing with hemp yarn grease, a rubber ring is added at the end of the casing, and then a waterproof coiled material is bonded to the wall-piercing pipe and the wall. Through an extrusion structure, the connection of the waterproof coiled material is ensured to be firm, and the waterproof performance of the wall-piercing pipe is ensured to be excellent. Content of the Utility Model

[0003] The purpose of the utility model is to provide a waterproof component for a building wall-piercing pipe, which has the advantages that after sealing with hemp yarn grease, a rubber ring is added at the end of the casing, and then a waterproof coiled material is bonded to the wall-piercing pipe and the wall. Through an extrusion structure, the connection of the waterproof coiled material is ensured to be firm, and the waterproof performance of the wall-piercing pipe is ensured to be excellent, so as to solve the above-mentioned background technical problems.

[0004] The technical solution of the utility model to solve the above technical problems is as follows: A waterproof component for a building wall-piercing pipe, which includes a steel casing body arranged in a wall: A wall-piercing pipe body penetrates through the inner cavity of the steel casing body, asphalt waterproof coiled materials are bonded between the two ends of the surface of the wall-piercing pipe body and the wall, a fixing shell sleeved on the surface of the wall-piercing pipe body is arranged outside the asphalt waterproof coiled materials, a plurality of tapping screws penetrate through the inner cavity of the fixing shell, the ends of the tapping screws penetrate into the wall, an inner wedge-shaped ring is arranged in the inner cavity of the fixing shell, a connecting shell is arranged on the surface of the fixing shell, a plurality of deformation columns are fixedly connected in an annular array in the inner cavity of the connecting shell, and an extrusion ball is fixedly connected to the end of the deformation column, and the extrusion ball presses on the outside of the asphalt waterproof coiled material.

[0005] Preferably, a water stop ring is welded in the middle of the surface of the steel casing body, and the water stop ring is embedded in the wall.

[0006] Preferably, a hemp yarn grease body is filled between the surfaces of the steel casing body and the wall-piercing pipe body, rubber rings sleeved on the surface of the wall-piercing pipe body are arranged at both ends of the inner cavity of the steel casing body, and the rubber rings are in contact with the inner sides of the asphalt waterproof coiled materials.

[0007] Preferably, a plurality of through holes for the tapping screws to pass through are opened in the inner cavity of the fixing shell.

[0008] Preferably, an external thread is provided on the surface of the fixed shell, and an internal thread adapted to the external thread is provided in the inner cavity of the connecting shell.

[0009] In the present utility model, a steel sleeve body is embedded in a wall body. After a wall-piercing pipe body passes through the steel sleeve body, a hemp yarn ointment body and a rubber ring are stuffed into the gap between the wall-piercing pipe body and the steel sleeve body. Then, an asphalt waterproof coiled material is bonded to the surfaces of the wall body and the wall-piercing pipe body. The fixed shell is installed on the wall body by tapping threads. Then, the connecting shell is screwed onto the surface of the fixed shell. During this process, the extrusion ball contacts the wedge surface of the inner wedge ring, causing the deformation column to deform. The extrusion ball abuts against the outer side of the asphalt waterproof coiled material due to the deformation of the deformation column, ensuring its sealing performance. That is, after using the hemp yarn ointment for plugging, a rubber ring is added at the end of the sleeve, and then the waterproof coiled material is bonded to the wall-piercing pipe and the wall body. Through the extrusion structure, the firm connection of the waterproof coiled material is ensured, and the excellent waterproof performance of the wall-piercing pipe is achieved.
