Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and in particular relates to a sealing structure for the penetration opening of a basement ventilation pipe. Background Technology

[0002] Basement ventilation refers to the process of exchanging and circulating air inside a basement through specific technologies and equipment to improve air quality, regulate temperature and humidity, meet the functional needs of the basement, and ensure the health of personnel and the normal operation of equipment. Due to its special spatial location, ventilation is a more prominent and important issue in basements compared to above-ground spaces.

[0003] In the construction of basement ventilation systems, ventilation ducts need to penetrate to the outside of the wall at the outdoor air outlet. Since basements are usually humid and may experience temperature fluctuations, these factors can cause the sealing material at the penetration point to age and deform, leading to gaps and seal failure. This results in water seepage and air leakage at the connection between the ventilation duct and the wall. Therefore, a sealing structure for the penetration point of basement ventilation ducts is needed. This structure uses a pre-embedded pipe sleeve to provide a foundation for the ventilation duct to penetrate the wall. The insulation board, rubber bushing, polyurethane filling layer, and cement mortar layer in the sealing component work together to achieve sealing protection, heat insulation, and waterproofing between the ventilation duct and the pre-embedded pipe sleeve, effectively preventing air leakage and water seepage, and improving heat insulation performance.

[0014] In the following description, embodiments of the basement ventilation pipe construction penetration sealing structure of this utility model will be described with reference to the accompanying drawings.

[0015] Figure 1-4 This invention illustrates a sealing structure for the penetration of a basement ventilation duct according to an embodiment of the present invention. The structure includes a pre-embedded pipe sleeve 1 embedded in the wall. A ventilation duct 2 is installed through the inner cavity of the pre-embedded pipe sleeve 1. A sealing component 3 is installed within the inner cavity of the pre-embedded pipe sleeve 1. The sealing component 3 includes multiple insulation boards 31 attached to the surface of the ventilation duct 2. A rubber bushing 32 is inserted into the left side of the pre-embedded pipe sleeve 1. Multiple water-blocking strips 33 are provided on the surface of the rubber bushing 32. The space between the insulation boards 31 and the rubber bushing 32 is filled with... A polyurethane filling layer 34 is provided. A cement mortar layer 35, filled and solidified on the surface of the ventilation duct 2, is provided on the right side of the embedded pipe sleeve 1. An outer cover 4 is fitted onto the surface of the ventilation duct 2 on the left side of the embedded pipe sleeve 1, and the outer cover 4 engages with the surface of the embedded pipe sleeve 1 and the rubber bushing 32. An inner cover 5 is fitted onto the surface of the ventilation duct 2 on the right side of the embedded pipe sleeve 1, and the inner cover 5 engages with the surface of the cement mortar layer 35. Screws 6 are inserted through the four corners of the opposite sides of the outer cover 4 and the inner cover 5. Screws 6 penetrate into the wall. Rubber gaskets 7 are fitted onto the surface of screws 6, and the surface of the rubber gaskets 7 fits tightly against the outer cover 4 and the inner cover 5. The screws 6 secure the outer cover 4 and the inner cover 5, ensuring they are stably fitted onto both sides of the embedded pipe sleeve 1. This provides shielding and protection for both sides of the embedded pipe sleeve 1 and the joint with the ventilation duct 2. Gaps between the outer cover 4 and the inner cover 5 and the wall and ventilation duct 2 are filled. There is a sealant layer 8, which is a weather-resistant silicone sealant. By setting the sealant layer 8, the joint between the outer cover 4, the inner cover 5, the ventilation pipe 2 and the wall is sealed, effectively preventing water seepage and improving the sealing effect of the ventilation pipe 2 after installation. The surface of the insulation board 31 is coated with adhesive 9, and the insulation board 31 is tightly attached to the surface of the ventilation pipe 2 by the adhesive 9. The surface of the pre-embedded pipe sleeve 1 is welded with a waterstop 10, which is located inside the wall.

[0016] Working principle: When using this utility model, firstly, the outer cover 4, inner cover 5, and water-blocking strip 33 are all fitted onto the surface of the ventilation pipe 2. Next, adhesive 9 is applied to the surface of the insulation board 31, and the insulation board 31 is bonded to the surface of the ventilation pipe 2. Then, the ventilation pipe 2 is inserted into the inner cavity of the pre-embedded pipe sleeve 1, so that the insulation board 31 is simultaneously located in the inner cavity of the pre-embedded pipe sleeve 1. Next, the user fills the left side of the insulation board 31 with the polyurethane filling layer 34, so that the pre-embedded pipe sleeve 1, the insulation board 31, and the ventilation pipe 2 are tightly connected. Finally, the rubber bushing 32 is pressed into the inner cavity of the pre-embedded pipe sleeve 1, so that the water-blocking strip 33 is squeezed out. Press the inner wall of the pre-embedded pipe sleeve 1, fill the right side of the insulation board 31 with cement mortar layer 35, and make the right side of the cement mortar layer 35 flush with the wall surface. Then, the user pushes the outer cover 4 and the inner cover 5 in opposite directions, so that the outer cover 4 and the inner cover 5 are both locked onto the surface of the insulation board 31, sealing both sides of the insulation board 31. The screws 6 are inserted into the wall through the outer cover 4 and the inner cover 5 respectively, and the outer cover 4 and the inner cover 5 are installed and fixed. After the installation is completed, the joint between the outer cover 4 and the inner cover 5 and the wall and the surface of the ventilation pipe 2 is filled with sealant layer 8 to seal it.

[0017] In summary, the sealing structure for the penetration of the basement ventilation duct, through the installation of the pre-embedded pipe sleeve 1, provides a penetration point for the ventilation duct 2 through the wall. Simultaneously, the sealing component 3 provides sealing protection and thermal insulation / waterproofing between the ventilation duct 2 and the pre-embedded pipe sleeve 1. Furthermore, the outer cover 4 and the inner cover 5 work together to further seal the penetration points on both the inner and outer sides of the wall, thus achieving effective thermal insulation protection and strong connection sealing performance.
