Description

Technical Field

[0001] This utility model belongs to the field of ventilation duct construction technology, and in particular relates to a sealing structure for roof exhaust pipes and pre-reserved holes in the roof. Background Technology

[0002] Exhaust duct construction is the process of building a system to expel polluted air from inside a building. Based on the design plan, appropriate materials such as metal and composite materials are selected to make exhaust ducts. During construction, the duct route and layout are precisely planned to avoid airflow obstruction. The exhaust ducts are installed securely using hangers and brackets to ensure their stability. Attention is paid to the sealing of the connections between each duct section to prevent air leakage.

[0003] In building roofing projects, roof exhaust pipes and pre-reserved holes in the roof need to be sealed to prevent rain and snow from entering. However, a single sealing method using sealing materials is difficult to completely and effectively prevent moisture penetration. Moreover, after installation, the sealing structure is easily loosened or displaced due to factors such as roof thermal expansion and contraction and wind force, which can damage the sealing effect. Therefore, it is necessary to provide a sealing structure for roof exhaust pipes and pre-reserved holes in the roof, which uses sealing components to achieve multiple seals at the top of the embedded pipe and the roof joint, effectively preventing moisture from seeping in from the top.

[0013] In the following description, embodiments of the roof exhaust pipe and roof pre-reserved hole sealing structure of the present invention will be described with reference to the accompanying drawings.

[0014] Figure 1-4 This invention illustrates a sealing structure for a roof vent pipe and a pre-reserved hole in the roof, comprising an embedded pipe 1 pre-embedded in the roof wall; a water-stop plate 2 fixedly connected to the surface of the embedded pipe 1; a sealing assembly 3 provided on the top of the surface of the embedded pipe 1; the sealing assembly 3 including an upper sealing plate 31 sleeved on the top of the surface of the embedded pipe 1; a sealing sleeve 32 integrally injection molded on the top of the upper sealing plate 31; and a second sealing gasket 8 bonded to the bottom of the upper sealing plate 31, the bottom of the second sealing gasket 8 being tightly fitted to the roof wall. The sealing sleeve 32 and the embedded pipe 1 are joined together, and a second sealant 10 is applied to the angle between the sealing sleeve 32 and the embedded pipe 1. A first sealant 9 is applied to the angle between the upper sealing plate 31 and the roof wall. Through the combined use of the second sealant 10 and the first sealant 9, the angles between the sealing sleeve 32 and the embedded pipe 1, and between the upper sealing plate 31 and the wall, are sealed, thereby further enhancing the sealing effect between the embedded pipe 1 and the wall. A rubber sealing ring 33 is fitted onto the top of the surface of the embedded pipe 1. An outer bevel 34 is provided, and an inner bevel 35 is provided at the top of the inner wall of the sealing sleeve 32. The inner bevel 35 and the outer bevel 34 are tightly fitted together. Multiple first expansion nails 36 are provided through the four corners of the top of the upper sealing plate 31. The bottom end of the first expansion nail 36 extends to the bottom of the upper sealing plate 31 and is fixedly connected to the roof wall. A lower sealing plate 4 is fitted onto the bottom of the surface of the embedded pipe 1. Second expansion nails 5 are provided through the four corners of the bottom of the lower sealing plate 4. The top end of the second expansion nail 5 extends to the top of the lower sealing plate 4 and is fixedly connected to the roof wall. The interior wall is fixedly connected. Through the cooperation of the lower sealing plate 4 and the second expansion nail 5, the first sealing gasket 7 is squeezed and limited, so that the first sealing gasket 7 can be tightly attached to the joint between the embedded pipe 1 and the interior wall, thereby sealing the embedded pipe 1 and the wall. The top of the lower sealing plate 4 is provided with an annular groove 6. The inner cavity of the annular groove 6 is fitted with the first sealing gasket 7. The first sealing gasket 7 is sleeved on the surface of the embedded pipe 1, and the top of the first sealing gasket 7 is tightly attached to the interior wall.

[0015] Working principle: When using this utility model, the user pre-embeds the pre-embedded pipe 1 inside the roof wall. After the wall is formed, the user presses the upper sealing plate 31 downwards, so that the upper sealing plate 31 is tightly attached to the surface of the roof wall. At the same time, the upper sealing plate 31 causes the sealing sleeve 32 to move, and the sealing sleeve 32 causes the rubber sealing ring 33 to slide downwards, so that the bottom of the rubber sealing ring 33 is tightly attached to the pre-embedded pipe 1 and the roof wall. Then, the first expansion nail 36 is drilled into the top of the upper sealing plate 31, so that the upper sealing plate 31 is fixedly connected to the roof wall. The compression of the inner inclined surface 35 and the inner inclined surface 35 Under the action of the rubber sealing ring 33, the rubber sealing ring 33 is stably wrapped around the surface of the pre-embedded pipe 1. Then, the user puts the first sealing gasket 7 on the bottom of the surface of the pre-embedded pipe 1 and puts the lower sealing plate 4 on the top of the surface of the pre-embedded pipe 1. The lower sealing plate 4 is fixedly connected to the indoor wall by the second expansion nail 5, so that the top of the first sealing gasket 7 is tightly pressed against the top of the indoor wall. Finally, the second sealant 10 and the first sealant 9 are applied at the angle between the pre-embedded pipe 1 and the sealing sleeve 32 and at the angle between the upper sealing plate 31 and the wall, respectively. After the first sealant 9 and the second sealant 10 have solidified, the process is complete.

[0016] In summary, the sealing structure between the roof exhaust pipe and the pre-reserved hole in the roof, through the setting of the sealing component 3, seals the joint between the top of the embedded pipe 1 and the roof. At the same time, with the cooperation of the water-stop plate 2, it provides water-stop protection for the embedded pipe 1 located inside the wall. Finally, with the cooperation of the lower sealing plate 4 and the first sealing gasket 7, it seals the joint of the embedded pipe 1 located inside the house. This achieves multiple sealing processes and effectively prevents water seepage.
