[0002] During construction, waterproofing is often required in areas such as basements and exterior walls, which necessitates the installation of waterproof membranes.

[0003] Existing exterior wall waterproof membranes are generally connected in a tight-fitting manner, but this method is difficult to connect and prone to cracking later on. Utility Model Content

[0004] The technical problem to be solved by this utility model is: In order to solve the technical problems in the prior art, this utility model provides an external wall vertical waterproof membrane staggered joint structure and a wall-penetrating pipe node structure.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a staggered joint structure of vertical waterproof membrane for exterior walls, including a first membrane, a second membrane and a cover strip, wherein the first membrane is laid on the second membrane, the cover strip covers both the first membrane and the second membrane, a first sealing element is provided between the first membrane and the cover strip, a second sealing element is provided between the second membrane and the cover strip, and a third sealing element is provided between the first membrane and the second membrane.

[0006] This utility model relates to a staggered joint structure for vertical waterproof membrane on exterior walls. The first and second membranes overlap, and then a cover strip is attached to both membranes to create a staggered joint. This staggered joint makes stress distribution more uniform, especially in areas sensitive to temperature-induced deformation (such as the base of the wall or at junctions), reducing the risk of tensile cracking. In addition, the staggered joint breaks the continuous path of water seepage along the joint, reducing the probability of leakage.

[0007] A through-wall pipe node structure includes a wall with through-wall holes through which a through-wall straight pipe passes. A first waterproof membrane is laid on one side of the outer side of the wall, through which the through-wall straight pipe passes. The first waterproof membrane is spliced ​​using the aforementioned staggered joint structure of vertical waterproof membrane for exterior walls.

[0008] Furthermore, an annular additional felt is provided between the first waterproof membrane and the wall.

[0009] Furthermore, a support ring is provided between the side wall of the through hole and the through straight pipe, and a wing plate is connected to the support ring. The wing plate contacts the end of the wall away from the first waterproof membrane.

[0010] Furthermore, a flange ring is provided between the support ring and the through-wall straight pipe, and the portion of the flange ring located outside the through-wall hole has a flange plate.

[0011] Furthermore, a caulking compound is provided between the through-wall straight pipe and the support ring, and the caulking compound is located at the end of the support ring near the first waterproof membrane.

[0012] Furthermore, asphalt-impregnated hemp fibers are provided between the through-wall straight pipe and the support ring, and the asphalt-impregnated hemp fibers are located at the end of the caulking compound away from the first waterproof membrane.

[0013] Furthermore, a retaining ring is provided between the through-wall straight pipe and the support ring.

[0014] Furthermore, a rubber ring is provided between the through-wall straight pipe and the support ring.

[0015] Furthermore, the side wall of the through hole is provided with a sealing groove and a water-stopping groove, the sealing groove is provided with a wing ring, and the water-stopping groove is provided with a water-stopping ring.

[0016] The beneficial effects of this utility model are:

[0017] 1. The first and second rolls of material are overlapped, and then a cover strip is overlapped on the first and second rolls to achieve staggered joints. The staggered joints make the stress distribution more uniform, especially in areas sensitive to temperature difference deformation (such as the root of the wall and the junction), which can reduce the risk of tensile cracking. In addition, the staggered joints can break the continuous path of water flow along the joint and reduce the probability of leakage.

[0018] 2. By combining the first waterproof membrane and the circular membrane with additional felt, the waterproof performance is further improved, and the connection strength between the first waterproof membrane and the through-wall straight pipe is increased, reducing the possibility of weak strength at the junction of the through-wall straight pipe and the wall.

[0019] 3. By setting support rings, flange rings, caulking compound, asphalt hemp fiber, retaining rings and rubber rings, the sealing performance between the through-wall straight pipe and the through-wall hole is improved, while providing strong support for the through-wall straight pipe.

[0027] This utility model discloses a staggered joint structure for vertical waterproof membrane on exterior walls and a through-wall pipe node structure.

[0028] Reference Figure 1A staggered joint structure for vertical waterproof membrane on exterior walls includes a first roll 1, a second roll 2, and a cover strip 3. The first roll 1 overlaps the second roll 2, and the cover strip 3 covers both the first roll 1 and the second roll 2. A first sealing element 31 is provided between the first roll 1 and the cover strip 3, a second sealing element 32 is provided between the second roll 2 and the cover strip 3, and a third sealing element 21 is provided between the first roll 1 and the second roll 2. The first roll 1 and the second roll 2 are first overlapped, and then the cover strip 3 is overlapped on top of the first roll 1 and the second roll 2 to achieve a staggered joint. The staggered joint makes the stress distribution more uniform, especially in areas sensitive to temperature deformation (such as the base of the wall and junctions), reducing the risk of tensile cracking. In addition, the staggered joint breaks the continuous path of water seepage along the joint, reducing the probability of leakage. The first sealing element 31, the second sealing element 32, and the third sealing element 21 can all be made of sealant.

[0029] A through-wall pipe joint structure, referring to Figure 2 The system includes a wall 4, which has a through-wall hole 41 through which a through-wall straight pipe 42 passes. A first waterproof membrane 5 is laid on the outer side of the wall 4, meaning the first waterproof membrane 5 is used on one side of the exterior wall of the wall 4. The through-wall straight pipe 42 passes through the first waterproof membrane 5, which is spliced ​​using the aforementioned staggered joint structure of the vertical waterproof membrane for exterior walls.

[0030] Reference Figure 3 The diagram shows the staggered joint of the first waterproof membrane 5, where the dotted line represents the inner membrane 91 and the solid line represents the outer membrane 92. The bottom of the wall 4 is also equipped with a permanent protective wall 9.

[0031] A ring-shaped additional felt 6 is provided between the first waterproof membrane 5 and the wall 4. The additional felt can be made of glass wool. The ring-shaped additional felt 6 includes an interconnected cylindrical part and a flat part. The cylindrical part is easy to fit onto the through-wall straight pipe 42 and fits tightly with the through-wall straight pipe 42. The flat part is easy to fit with the wall 4. The cylindrical part and the flat part work together to fill the junction between the through-wall straight pipe 42 and the wall 4.

[0032] Specifically, a support ring 7 is provided between the side wall of the through-hole 41 and the through-wall straight pipe 42. A flange 71 is fixedly connected to the support ring 7, and the flange 71 contacts the end of the wall 4 away from the first waterproof membrane 5. A flange ring 8 is also provided between the support ring 7 and the through-wall straight pipe 42. The portion of the flange ring 8 located outside the through-hole 41 is fixedly connected to the flange 81. Through the cooperation of the support ring 7 and the flange ring 8, good support is achieved for the through-wall straight pipe 42.

[0033] A sealant 72 is provided between the through-wall straight pipe 42 and the support ring 7, with the sealant 72 located at the end of the support ring 7 closest to the first waterproof membrane 5. Asphalt-impregnated hemp fibers 73 are also provided between the through-wall straight pipe 42 and the support ring 7, located at the end of the sealant 72 furthest from the first waterproof membrane 5. The asphalt-impregnated hemp fibers 73 and the sealant 72 work together to improve the seal between the support ring 7 and the through-wall straight pipe 42, thereby better sealing the outer side of the wall 4.

[0034] In addition, a retaining ring 74 is provided between the through-wall straight pipe 42 and the support ring 7, and a rubber ring 75 is provided between the through-wall straight pipe 42 and the support ring 7. The rubber ring 75 is located between the retaining ring 74 and the flange ring 8, further improving the seal between the support ring 7 and the through-wall straight pipe 42. In this embodiment, two rubber rings 75 can be provided.

[0035] It should be noted that the side wall of the through-hole 41 is also provided with a sealing groove and a water-stopping groove. The sealing groove contains a wing ring 43, and the water-stopping groove contains a water-stopping ring 44. The wing ring 43 enhances the connection between the support ring 7 and the wall 4, preventing the support ring 7 from loosening or detaching, and ensuring the stability of the support ring 7. The water-stopping ring 44 is used to improve the sealing between the support ring 7 and the wall 4, preventing water from passing through.

[0036] Working principle: The first roll 1 and the second roll 2 are overlapped, and then the cover strip 3 is overlapped on the first roll 1 and the second roll 2 to achieve staggered joints. The staggered joints make the stress distribution more uniform, especially in areas sensitive to temperature difference deformation (such as the base of the wall and the junction), which can reduce the risk of tensile cracking. In addition, the staggered joints can break the continuous path of water flow along the joint and reduce the probability of leakage.

[0037] The combination of the first waterproof membrane 5 and the annular additional felt 6 further enhances the waterproof performance and strengthens the connection between the first waterproof membrane 5 and the through-wall pipe 42, reducing the possibility of weaker strength at the junction of the through-wall pipe 42 and the wall 4. The installation of the support ring 7, flange ring 8, caulking compound 72, asphalt hemp fiber 73, retaining ring 74, and rubber ring 75 improves the sealing between the through-wall pipe 42 and the through-wall hole 41, while also providing strong support for the through-wall pipe 42.
