Technical Field

[0001] This application relates to the field of pipe waterproofing technology, and in particular to a waterproof structure for pipes penetrating roofs. Background Technology

[0002] In the construction of high-rise residential buildings, the installation of water supply and drainage pipes is an essential step. Water supply and drainage pipes usually need to be installed through walls. In the early stages of construction, it is necessary to first build the walls or pour the interlayer slabs, and reserve holes for the installation of pipes at the locations where the water supply and drainage pipes pass through, so that the water supply and drainage pipes can be installed in the later stages of the high-rise building project.

[0003] Existing waterproof structures are prone to leakage after prolonged use and cannot be maintained for a long time. Furthermore, existing waterproof structures are not convenient to maintain regularly after installation, resulting in maintenance difficulties. Therefore, this application proposes a waterproof structure for pipes penetrating the roof to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a waterproof structure for pipes penetrating the roof, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0005] To achieve the above objectives, this application adopts the following technical solution: a waterproof structure for a pipe penetrating a roof, comprising a roof surface layer, an insulation layer fixedly installed at the bottom of the roof surface layer, a concrete roof panel installed at the bottom of the insulation layer, a pipe body installed on the inner wall of the roof surface layer, the insulation layer and the concrete roof panel, a water-stop wing ring sleeved on the outer edge of the pipe body, a waterproof sleeve installed on the top of the roof surface layer, and the inner wall of the waterproof sleeve filled with sealant.

[0006] In a preferred embodiment, the inner walls of the roof surface layer, the insulation layer, and the concrete roof panel are all perforated, and the pipe body is installed on the inner wall of the perforation.

[0007] By adopting the above technical solution, the pipe body can be stably installed on the inner wall of the roof surface layer, insulation layer and concrete roof panel, and then it can be used for water circulation.

[0008] In a preferred embodiment, the bottom of the water-stop ring is fitted to the top of the roof surface layer, and the inner diameter of the water-stop ring is adapted to the outer diameter of the pipe body.

[0009] By adopting the above technical solution, the connection gap between the water-stop ring and the pipe body and the perforation can be sealed, ensuring that water will not penetrate into the gap between the water-stop ring and the perforation, and thus will not easily penetrate into the roof surface layer, insulation layer and inner wall of concrete roof panel, and thus will not enter the room.

[0010] In a preferred embodiment, the sealant is polyurethane or polyethylene foam.

[0011] By adopting the above technical solution, it can be used to fill the gap between the waterproof sleeve and the water-stop ring, thereby filling tiny gaps and further ensuring the sealing performance.

[0012] In a preferred embodiment, a semicircular disc 1 and a semicircular disc 2 are symmetrically installed on the outer edge of the waterproof sleeve. Side plates are installed on the outer sides of both the semicircular disc 1 and the semicircular disc 2. A bolt passes through the inner wall of the semicircular disc 2, and a nut is threaded onto the outer edge of the bolt.

[0013] By adopting the above technical solution, it can be used to position the waterproof sleeve, ensuring the stability of the waterproof sleeve when it is installed on the top of the roof surface layer, and thus ensuring that the sealant will not easily shift its position when it expands inside the waterproof sleeve.

[0014] In a preferred embodiment, the outer edges of both the first and second semicircular disks are coated with a galvanized layer.

[0015] By adopting the above technical solution, it is possible to ensure that semi-disc one and semi-disc two, when exposed to rain and air, will not be easily corroded, thus ensuring durability and service life.

[0016] The beneficial effects of this application are:

[0017] This waterproof structure for pipes penetrating roofs uses a water-stop wing ring that abuts against the top of the roof surface to seal the connection gap between the pipe body and the perforation. By filling the inner wall of the waterproof sleeve with sealant, the gap between the waterproof sleeve and the water-stop wing ring is filled, which can be used to fill tiny gaps, further ensuring the seal and preventing water from easily penetrating to the inner wall of the perforation.

[0018] This waterproof structure for pipes penetrating roofs facilitates the release of the waterproof sleeve by setting up semi-circular disc one, semi-circular disc two, side plates, bolts, and nuts, thereby facilitating the inspection and maintenance of the seepage location.

[0024] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0025] Reference Figure 1-4 A waterproof structure for a pipe penetrating a roof includes a roof surface layer 1, an insulation layer 2 fixedly installed at the bottom of the roof surface layer 1, a concrete roof panel 3 installed at the bottom of the insulation layer 2, a pipe body 4 installed on the inner wall of the roof surface layer 1, the insulation layer 2 and the concrete roof panel 3, a water-stop wing ring 6 sleeved on the outer edge of the pipe body 4, and a waterproof sleeve 8 installed on the top of the roof surface layer 1, with the inner wall of the waterproof sleeve 8 filled with sealant 7.

[0026] See Figures 1-2 The inner walls of the roof surface layer 1, the insulation layer 2, and the concrete roof panel 3 are all perforated with a perforation 5. The pipe body 4 is installed on the inner wall of the perforation 5, so that the pipe body 4 can be stably installed on the inner walls of the roof surface layer 1, the insulation layer 2, and the concrete roof panel 3, and can then be used for water circulation.

[0027] See Figure 2 and Figure 3 The bottom of the water-stop ring 6 is fitted to the top of the roof surface layer 1, and the inner diameter of the water-stop ring 6 is matched with the outer diameter of the pipe body 4, so that the connection gap between the water-stop ring 6 and the pipe body 4 and the perforation 5 can be sealed, ensuring that water will not penetrate into the gap between the water-stop ring 6 and the perforation 5, and thus will not easily penetrate into the inner wall of the roof surface layer 1, the insulation layer 2 and the concrete roof panel 3, and thus will not enter the room.

[0028] See Figure 2 and Figure 3 The sealant 7 is made of polyurethane or polyethylene foam, which can be used to fill the gap between the waterproof sleeve 8 and the water-stop ring 6, thereby filling tiny gaps and further ensuring the seal.

[0029] See Figure 1 and Figure 4The outer edge of the waterproof sleeve 8 is symmetrically equipped with a semi-circular disc 9 and a semi-circular disc 10. Side plates 11 are installed on the outer sides of both the semi-circular disc 9 and the semi-circular disc 10. Bolts 12 are passed through the inner wall of the semi-circular disc 10. Nuts 13 are threaded on the outer edge of the bolts 12, which can be used to position the waterproof sleeve 8 and ensure the stability of the waterproof sleeve 8 when it is set on the top of the roof surface layer 1. This also ensures that the sealant 7 will not easily shift its position when it expands on the inner wall of the waterproof sleeve 8.

[0030] See Figure 4 Both the outer edges of the first half-disc 9 and the second half-disc 10 are coated with a galvanized layer, which ensures that the first half-disc 9 and the second half-disc 10 will not easily rust when exposed to rain and air, thus ensuring durability and service life.

[0031] Working principle: When using this device, firstly, the pipe body 4 can be inserted into the inner wall of the perforation 5. Then, the water-stop ring 6 can be abutted against the top of the roof surface layer 1 to seal the connection gap between the pipe body 4 and the perforation 5. Then, the water-stop ring 6 can be fitted onto the outer edge of the pipe body 4. Then, the semi-circular disc 1 9 and the semi-circular disc 2 10 can be symmetrically installed onto the outer edge of the waterproof sleeve 8. Then, the semi-circular disc 1 9 and the semi-circular disc 2 10 can be firmly connected with bolts 12 and nuts 13 and installed on the outer edge of the waterproof sleeve 8. Then, the sealant 7 can be filled into the inner wall of the waterproof sleeve 8 to fill the gap between the waterproof sleeve 8 and the water-stop ring 6. This can be used to fill tiny gaps, further ensuring the sealing performance and preventing water from easily penetrating into the inner wall of the perforation 5.
