Description

Technical Field

[0001] The utility model relates to the field of wall pipe waterproofing, and more specifically, to a wall-penetrating pipe waterproofing structure. Background Art

[0002] In recent years, with the rapid development of the construction industry, it is often necessary to install pipes through walls in construction projects. When laying lines and pipes, sometimes the pipes pass through the outer wall. During the installation of the through-wall pipe, it is necessary to drill holes first. Due to construction reasons, there will inevitably be some gaps between the installation hole and the through-wall pipe. Even if the waterproof material is filled, it is difficult to completely fill the gap between the installation hole and the through-wall pipe, which makes it difficult to maintain a high waterproof effect between the hole and the through-wall pipe. At present, the waterproof work done for the pipeline through the wall is relatively simple, and the ideal waterproof effect cannot be achieved. There is still room for improvement. We need to study the waterproof structure method with better waterproof effect. Utility Model Content

DETAILED DESCRIPTION

[0025] Reference Figure 1 to Figure 2 The utility model is further described in detail.

[0026] A wall-penetrating pipe waterproof structure comprises a pipe 1 and a waterproof pipe sleeve 12, wherein the waterproof pipe sleeve 12 is sleeved on the pipe 1, and the pipe 1 is penetrated through a wall, comprises a fastener 2 and a waterproof block 31, the waterproof block 31 is arranged at the connection between the pipe 1 and the wall, the fastener 2 presses the waterproof block 31 to drive it to be close to the wall and the pipe 1, the fastener 2 comprises a second sealing block 3, the second sealing block 3 is arranged on one side of the fastener 2 close to the pipe 1, and the second sealing block 3 is locked with the fastener 2 to be close to the pipe 1.

[0027] The fastener 2 includes a first fixing ring 32 and a second fixing ring 33 rotatably connected thereto. A locking portion 34 is provided on the second fixing ring 33 . The two are in a snap ring shape to facilitate locking.

[0028] The waterproof block 31 includes a first sealing portion 35 , a compression surface is provided on the side of the first sealing portion 35 facing the outside, a second sealing segment 36 and a third sealing segment 37 are respectively extended from both ends of the first sealing portion 35 , and the second sealing segment 36 is fixed with the first fixing ring 32 and the second fixing ring 33 to be tightly attached to the pipeline 1 .

[0029] The fastener 2 includes a second locking block 4. The first fixing ring 32 and the second fixing ring 33 both have locking portions extending therefrom. The second locking block 4 is clamped on the locking portions. The bolts pass through the second locking block 4 and the third sealing section 37 to press the third sealing section 37 against the wall.

[0030] A fourth sealing portion 41 extends from the first sealing portion 35 near the connection between the pipe 1 and the wall, and the fourth sealing portion 41 extends into the wall.

[0031] The waterproof pipe sleeve 12 is provided with a polyurethane expansion sealant 5 .

[0032] A water-stop wing ring 6 is provided on the waterproof pipe sleeve 12 .

[0033] An acrylic acid salt spray film waterproof layer 7 is sprayed at the connection between the pipeline 1 and the wall.

[0034] A tightening member 71 is provided at one end of the locking member close to the second sealing block 3 .

[0035] Instructions for use: During use, use the wing ring to install the sleeve into the wall, then pass the wall-penetrating pipe through the wall hole, first inject polyurethane expansion sealant 5 into the gap between the wall-penetrating pipe and the sleeve, and then inject sealing sealant into the two ends of the polyurethane expansion sealant 5. After the sealing sealant solidifies, set the acrylic acid spray waterproof layer 7 on the outer wall of the wall-penetrating pipe and the wall. The setting of polyurethane foam filler and sealing sealant effectively prevents water from seeping in from the gap between the wall-penetrating pipe and the sleeve. The setting of acrylic acid spray waterproof layer 7 effectively prevents water from seeping in from the gap between the wall-penetrating pipe and the sleeve. The waterproof node of the wall-penetrating pipe achieves waterproof effect through the close combination of the two sealing materials inside the seal, and the outer waterproof coating reinforcement layer further reduces the risk of leakage, bringing better user experience.
