DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with embodiments.

[0023] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0024] In the examples, unless otherwise specified, all the means used are conventional means in the art.

[0025] See also Figure 1-Figure 4 A high airtight wall-penetrating pipeline structure includes a connecting component 100 and an insulation component 200.

[0026] See also Figure 1 and 2 The connection assembly 100 includes a concrete wall 110, a wing ring tube 120, a polyurethane foam layer 130 and a sealing film layer 150. The wing ring tube 120 is pre-buried in the concrete wall 110, the polyurethane foam layer 130 is arranged in the wing ring tube 120, and the sealing film layer 150 is arranged on the wall surface of the concrete wall 110.

[0027] The wing ring tube 120 includes a wing ring plate 121 and a pipe 122. The wing ring plate 121 and the pipe 122 are integrally formed. The wing ring plate 121 is embedded in the concrete wall 110. The pipe 122 runs through the concrete wall 110. By setting the wing ring plate 121 and the pipe 122, the wing ring plate 121 is set on the outside of the pipe 122 and embedded in the concrete wall 110 in a radial manner, which can improve the axial stability of the pipe 122.

[0028] Among them, the sealing membrane layer 150 includes a waterproof and breathable membrane 151 and a waterproof and vapor-proof membrane 152. The waterproof and breathable membrane 151 is located on the outside of the concrete wall 110, and the waterproof and vapor-proof membrane 152 is located on the inside of the concrete wall 110. By arranging the waterproof and vapor-proof membrane 152 on the inside of the concrete wall 110, it is possible to isolate indoor water vapor and prevent water vapor from invading the interior and causing mold and the like.

[0029] See also Figure 1 , 2 , 3 and 4, the insulation assembly 200 includes an insulation layer 210, a wall-penetrating pipe 220 and a fixed seal 230, the insulation layer 210 is located on the outside of the concrete wall 110, the wall-penetrating pipe 220 penetrates the insulation layer 210, and the fixed seal 230 is arranged between the insulation layer 210 and the wall-penetrating pipe 220.

[0030] Among them, the fixed sealing member 230 includes a first pre-compression expansion sealing band 231 and a second pre-compression expansion sealing band 232. The first pre-compression expansion sealing band 231 and the second pre-compression expansion sealing band 232 are both sleeved on the outside of the wall-penetrating pipe 220. The first pre-compression expansion sealing band 231 is located on one side of the insulation layer 210, and the second pre-compression expansion sealing band 232 is located on the other side of the insulation layer 210. By setting the first pre-compression expansion sealing band 231 and the second pre-compression expansion sealing band 232, the wall-penetrating pipe 220 is vertically and stably fixed in the insulation layer 210 by utilizing the first pre-compression expansion sealing band 231 and the second pre-compression expansion sealing band 232. It can be installed in advance to avoid temporary installation on site and improve on-site installation efficiency.

[0031] It should be noted that the wall-penetrating tube 220 and the first pre-pressure expansion sealing belt 231 are interference fit, and the wall-penetrating tube 220 and the second pre-pressure expansion sealing belt 232 are interference fit. By setting the wall-penetrating tube 220 and the pre-pressure expansion sealing belt connected by interference fit, not only the restraining and fixing ability of the wall-penetrating tube 220 is guaranteed, but also the sealing is guaranteed to prevent the intrusion of water vapor.

[0032] Specifically, the insulation layer 210 is provided with a through hole 211 and a limiting groove 212, the wall-penetrating pipe 220 passes through the through hole 211, the first pre-pressure expansion sealing belt 231 and the second pre-pressure expansion sealing belt 232 are respectively arranged in the two limiting grooves 212, and by providing the through hole 211 and the limiting groove 212, the limiting groove 212 is used to limit and accommodate the pre-pressure expansion sealing belt, thereby limiting the axial movement of the wall-penetrating pipe 220.

[0033] In this embodiment, the insulation component 200 further includes an adhesive layer 240 , and the adhesive layer 240 is located between the concrete wall 110 and the insulation layer 210 . The adhesive layer 240 is provided to achieve connection between the insulation layer 210 and the concrete wall 110 .

[0034] Among them, a waterproof coating reinforcement layer 250 is arranged on the outside of the insulation layer 210. By setting the waterproof coating reinforcement layer 250, not only the first pre-compression expansion sealing belt 231 is shielded and covered, but also the risk of leakage is further reduced, bringing a better use experience to the user.

[0035] The working principle of the high airtight wall-penetrating pipeline structure is as follows: first, by pre-embedding, when constructing the concrete wall 110, the wing ring plate 121 is arranged on the outside of the pipeline 122 and pre-embedded into the concrete wall 110 in a radial manner, which can improve the axial stability of the pipeline 122. When installing the insulation layer 210, the wall-penetrating pipe 220 is first passed through the through hole 211, and the first pre-pressure expansion sealing belt 231 and the second pre-pressure expansion sealing belt 232 are both sleeved on the wall-penetrating pipe 220, and the two pre-pressure expansion sealing belts The waterproof and breathable membrane 151 is laid on the outside of the concrete wall 110. When the insulation layer 210 is installed, the wall-penetrating pipe 220 passes through the pipe 122. Then, a polyurethane foam sealant is injected between the wall-penetrating pipe 220 and the pipe 122 to form a polyurethane foam layer 130. The wall-penetrating pipe 220 and the pipe 122 are fixedly bonded by the adhesiveness of the polyurethane foam. If the concrete wall 110 is directly bonded, the adhesiveness is poor and the sealing is poor. Also poor, finally laying waterproof vapor barrier membrane 152, can isolate indoor water vapor, prevent water vapor from invading the interior, causing mold and other phenomena, a waterproof coating reinforcement layer 250 is arranged outside the thermal insulation layer 210, not only to cover the first pre-compression expansion sealing belt 231, but also to further reduce the risk of leakage, bringing better user experience, the first pre-compression expansion sealing belt 231 and the second pre-compression expansion sealing belt 232 are used to vertically and stably fix the through-wall pipe 220 in the thermal insulation layer 210, which can be installed in advance to avoid temporary installation on site, improve the on-site installation efficiency, and at the same time ensure the verticality of the through-wall pipe 220, even if the wing ring pipe 120 is tilted a little in the embedded type, the through-wall pipe 220 can also ensure the vertical angle, the wing ring plate 121 is arranged on the outside of the pipe 122, and is radially embedded in the concrete wall 110, and the pipe 122 and the pipe 122 are bonded by the polyurethane foam layer 130, which effectively ensures the stability and airtightness in the later stage, and the overall exterior is smooth and beautiful.
