[0036] like Figure 1 and Figure 2 As shown, some embodiments of the utility model provide a roof waterproof structure, which is mainly used for waterproofing roof pipes to avoid water seepage or leakage and improve the quality of roof waterproofing.

[0037] The roof waterproof structure includes a roof panel 100 , an exhaust pipe 200 , a waterproof board 300 , a connecting pipe 400 and a sealing layer 500 .

[0038] The roof panel 100 is provided with a mounting hole, and the mounting hole penetrates the roof panel 100 along the thickness direction of the roof panel 100 .

[0039] In addition, the exhaust pipe 200 is passed through the mounting hole, and the outer wall of the exhaust pipe 200 abuts against the hole wall of the mounting hole to form a sealed connection structure between the outer wall of the exhaust pipe 200 and the hole wall of the mounting hole, thereby improving the stability and sealing of the connection between the exhaust pipe 200 and the hole wall of the mounting hole.

[0040] It can be understood that the axis of the exhaust pipe 200 coincides with the axis of the mounting hole.

[0041] The waterproof board 300 is arranged on one side of the roof panel 100 in the thickness direction, and the waterproof board 300 and the roof panel 100 are stacked, that is, the side of the waterproof board 300 facing the roof panel 100 is in contact with the side of the roof panel 100 facing the waterproof board 300.

[0042] The connection method between the waterproof board 300 and the roof panel 100 includes any one of bonding, clamping, and bolting, which can be specifically set according to actual conditions.

[0043] It can be understood that the detachable connection between the waterproof board 300 and the roof panel 100 can not only improve the stability of the connection between the waterproof board 300 and the roof panel 100, but also improve the installation or disassembly efficiency between the waterproof board 300 and the roof panel 100, so as to facilitate maintenance or replacement.

[0044] Specifically, the waterproof board 300 is provided with a through hole, the exhaust pipe 200 passes through the through hole, and the outer wall of the exhaust pipe 200 abuts against the hole wall of the through hole, so that the waterproof board 300 is sleeved on the exhaust pipe 200, so as to form a limiting effect on the waterproof board 300 through the exhaust pipe 200, so as to improve the stability of the waterproof board 300 on the roof panel 100.

[0045] In this embodiment, the connecting pipe 400 is sleeved on the exhaust pipe 200, and there is a gap between the connecting pipe 400 and the exhaust pipe 200 to define a receiving cavity between the connecting pipe 400 and the exhaust pipe 200, and one end of the connecting pipe 400 facing the waterproof board 300 is sealed and connected to the waterproof board 300. The axis of the exhaust pipe 200 coincides with the axis of the connecting pipe 400.

[0046] In addition, the connection method between the connecting pipe 400 and the waterproof plate 300 includes any one of bonding, clamping, and threaded connection, which can be specifically set according to actual conditions.

[0047] Among them, the sealing layer 500 is arranged in the accommodating cavity, and the inner wall of the connecting pipe 400 is sealed and connected with the outer wall of the exhaust pipe 200 through the sealing layer 500 to form a sealed connection structure to prevent external liquid from penetrating into the roof panel 100 from between the connecting pipe 400 and the exhaust pipe 200.

[0048] It can be understood that the side of the sealing layer 500 facing away from the exhaust pipe 200 is connected to the inner wall of the connecting pipe 400 , and the side of the sealing layer 500 facing the exhaust pipe 200 is sealed and connected to the outer wall of the exhaust pipe 200 .

[0049] Specifically, in this embodiment, the sealing layer 500 is a concrete layer, so as to improve the mechanical properties and durability of the roof waterproof structure through the concrete layer, so as to ensure the compactness and strength of the roof waterproof structure.

[0050] In this embodiment, the connecting pipe 400 is a PVC (Polyvinylchlorid) pipe, which has the characteristics of good tensile and compressive strength, small fluid resistance, excellent corrosion resistance and chemical resistance, good water tightness, etc.

[0051] It can be understood that by arranging a waterproof board 300 on the roof panel 100 to improve the waterproof quality of the roof panel 100, by arranging the connecting pipe 400 on the exhaust pipe 200 to define a accommodating cavity, and arranging the sealing layer 500 in the accommodating cavity to form a sealed connection structure on the outer wall of the exhaust pipe 200, not only the waterproof quality between the exhaust pipe 200 and the roof panel 100 can be improved, but also the local strength of the exhaust pipe 200 can be improved.

[0052] Furthermore, a waterproof coating is provided on the surface of the sealing layer 500, and the waterproof coating is a cement-based penetrating crystalline waterproof coating layer.

[0053] It should be noted that the silicone ions dissolved in the cement-based penetrating crystallization waterproof coating diffuse in the concrete along with the surface water, and react chemically with the calcium ions in the concrete to generate water-insoluble calcium silicate hydrates (dendritic crystals). The crystals fill the capillary pores and combine with the concrete to form a whole, blocking the capillary channels inside the concrete, thereby making the concrete dense and preventing water leakage. In addition, the cement-based penetrating crystallization waterproof coating has catalytic properties. Once it encounters water, it can continuously produce chemical reactions. The generated crystals continue to grow and fill the capillary pores inside the concrete. Therefore, even if the concrete structure is partially damaged and leaks, it will produce crystallization after encountering water and heal itself (0.4mm cracks).

[0054] The crystals produced by cement-based penetrating crystalline waterproof coating can repair cracks of 0.4mm. Therefore, for cracks of 0.4mm, cement-based penetrating crystalline waterproof coating has the effect of self-repair and healing, and no other waterproof layer repair is needed. Cement-based penetrating crystalline waterproof coating has the characteristics and performance of multiple anti-seepage and self-repair, and has extremely strong compressive resistance, up to 3.0MPa. The waterproof layer and the concrete surface form a complete system and will not separate. The material can fully absorb moisture on the concrete surface to participate in its crystallization reaction, and no hollowing phenomenon will occur.

[0055] In some embodiments, the hole wall of the through hole is provided with an annular groove, the axis of the annular groove coincides with the axis of the through hole, and a rubber ring is provided in the annular groove, the rubber ring abuts against the groove wall of the annular groove, and the side of the rubber ring facing the exhaust pipe 200 abuts against the exhaust pipe 200 to form a sealing connection structure between the hole wall of the through hole and the outer wall of the exhaust pipe 200 to improve the sealing quality between the waterproof plate 300 and the exhaust pipe 200.

[0056] like Figure 2 As shown, in some embodiments of the present invention, the hole wall of the mounting hole is provided with at least one first annular groove.

[0057] It can be understood that the number of the first annular grooves can be one, two, or any number above two, and can be specifically set according to actual conditions.

[0058] In addition, a first sealing ring 600 is provided in each of the first annular grooves. It can be understood that the number of the first sealing rings 600 is equal to the number of the first annular grooves, and the first sealing rings 600 abut against the inner wall of the first annular groove, and the first sealing ring 600 abuts against the exhaust pipe 200 on the side facing the exhaust pipe 200, so as to form a sealed connection structure between the hole wall of the mounting hole and the outer wall of the exhaust pipe 200, thereby improving the sealing quality of the connection between the exhaust pipe 200 and the roof panel 100.

[0059] In some embodiments, there are multiple first annular grooves, and the multiple first annular grooves are arranged at equal intervals along the axial direction of the exhaust pipe 200. It can be understood that by providing multiple first annular grooves, a multiple sealing and waterproof structure is formed between the exhaust pipe 200 and the hole wall of the mounting hole, thereby effectively preventing external liquid from penetrating into the roof panel 100, so as to further improve the sealing quality between the exhaust pipe 200 and the roof panel 100.

[0060] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, along the axis direction of the exhaust pipe 200, the length of the sealing layer 500 is greater than the length of the connecting pipe 400. It can be understood that a portion of the sealing layer 500 away from the waterproof board 300 is located outside the connecting pipe 400.

[0061] Specifically, the sealing layer 500 is tapered from one end close to the connecting pipe 400 and away from the waterproof board 300 to the end away from the connecting pipe 400, that is, the end of the sealing layer 500 away from the waterproof board 300 is in a truncated cone shape, so as to provide a guiding effect for the liquid through the inclined surface of the truncated cone, so that the liquid can flow toward the outer wall of the connecting pipe 400 through the end of the sealing layer 500 away from the waterproof board 300, thereby avoiding the liquid from gathering between the connecting pipe 400 and the exhaust pipe 200.

[0062] like Figure 2 and Figure 3As shown, in some embodiments of the utility model, a second annular groove 310 is provided on the side of the waterproof board 300 facing away from the roof panel 100, and one end of the connecting pipe 400 is at least partially accommodated in the second annular groove 310, and the tube wall of the connecting pipe 400 abuts against the groove wall of the second annular groove 310, so as to provide a limiting effect on the connecting pipe 400 through the second annular groove 310, thereby improving the stability of the connection between the connecting pipe 400 and the waterproof board 300.

[0063] The connection method between the connecting rod and the waterproof plate 300 includes any one of bonding, clamping, and threaded connection, which can be specifically set according to actual conditions.

[0064] In some embodiments, the inner wall of the second annular groove 310 is provided with an internal thread, and the end of the connecting pipe 400 close to the waterproof board 300 is provided with an external thread, and the internal thread is adapted to the external thread, that is, the connecting pipe 400 is threadedly connected to the groove wall of the second annular groove 310 to threadably connect the connecting pipe 400 to the waterproof board 300, so as to improve the stability of the connection between the connecting pipe 400 and the waterproof board 300.

[0065] like Figure 2 As shown, in some embodiments of the present invention, a sealing gasket 700 is provided at the bottom of the second annular groove 310. The sealing gasket 700 may be a silicone sheet or a rubber sheet, which may be specifically set according to actual conditions.

[0066] Along the axial direction of the exhaust pipe 200, one side of the sealing gasket 700 abuts against the bottom of the second annular groove 310, and the other side of the sealing gasket 700 abuts against one end of the connecting pipe 400 toward the waterproof plate 300, so as to form a sealing connection structure between the waterproof plate 300 and the connecting pipe 400, so as to improve the sealing quality of the connection between the waterproof plate 300 and the connecting pipe 400.

[0067] It can be understood that by sealing the connecting pipe 400 and the waterproof board 300, a sealed connection structure is formed on the periphery of the exhaust pipe 200 to prevent external liquid from penetrating into the connection between the exhaust pipe 200 and the roof panel 100, thereby improving the sealing quality and waterproof quality between the exhaust pipe 200 and the roof panel 100.

[0068] In some embodiments of the present invention, a waterproof layer is provided on the side of the roof panel 100 facing the waterproof board 300 , and the waterproof layer is used to prevent liquid from penetrating into the roof panel 100 to ensure the service life of the roof panel 100 .

[0070] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, a limiting ring 800 is provided on the side of the waterproof board 300 facing away from the roof panel 100 .

[0071] Specifically, the limiting ring 800 is sleeved on the connecting pipe 400, and the limiting ring 800 is threadedly connected to the connecting pipe 400, and one end of the limiting ring 800 facing the waterproof board 300 abuts against the waterproof board 300, so that the limiting ring 800 forms a limiting effect on the waterproof board 300, so as to further improve the stability of the connection between the waterproof board 300 and the roof panel 100, and at the same time, it is easy to remove the waterproof board 300 from the roof panel 100 for easy maintenance or replacement.

[0072] In some embodiments of the utility model, a sealant is provided around the edge of the waterproof board 300, that is, the sealant is provided along the edge of the waterproof board 300 and around the circumference of the waterproof board 300, and the sealant is connected to the roof panel 100, so as to form a sealed connection structure by connecting the waterproof board 300 to the roof panel 100 at the edge of the waterproof board 300 through the sealant, thereby preventing the liquid on the outer wall from seeping into the space between the roof panel 100 and the exhaust pipe 200 from between the waterproof board 300 and the roof panel 100, thereby improving the waterproof quality of the roof panel 100.
