Description

Technical Field

[0001] This utility model belongs to the field of concrete wall technology, specifically relating to a seepage-resistant structure for building concrete wall panels. Background Technology

[0002] In practical applications, the joints between traditional concrete wall panels used for waterproofing are roughened to create a connection between the upper and lower concrete walls. This connection makes it easy for water to seep through the gaps in the structure. Furthermore, the waterproofing design on the inner side of the wall is relatively simple, relying on a single layer of waterproofing components or a single sealing material. It does not construct a multi-dimensional sealing and protection system, which cannot fully fill the tiny gaps between the wall and the components. It also lacks a targeted anti-seepage diffusion structure, making it easy for water to seep in from the point where the waterproofing components are attached to the wall. It is difficult to effectively block water penetration in the long term and cannot meet the building's requirements for high waterproofing performance. Utility Model Content

[0003] To address the above problems, the purpose of this utility model is to provide a waterproof structure for building concrete wall panels, thereby solving the aforementioned issues.

[0004] To achieve the above objectives, a waterproofing structure for a building concrete wall panel includes a concrete wall A and a concrete wall B. A groove is formed at the connection between the concrete wall A and the concrete wall B. A protrusion is integrally cast at the bottom of the groove, and the groove and the protrusion match. A steel reinforcement skeleton A and a steel reinforcement skeleton B are installed inside the concrete wall A and the concrete wall B, respectively, with their upper and lower joints. A sealing groove is formed on the inner side of the concrete wall B, and a waterproof membrane is attached to the inner side of the concrete wall B. A waterproof groove is formed on the top of the inner wall of the sealing groove. The sealing groove, the waterproof membrane, and the waterproof groove are filled with asphalt-based sealant.

[0005] Preferably, the outer surfaces of the concrete wall A and the concrete wall B are provided with a base layer, a cement mortar leveling layer, and a waterproof coating.

[0006] Preferably, the steel reinforcement cage A and the steel reinforcement cage B are connected by a welded joint, and the bottom of the waterproof membrane is in contact with the floor slab surface.

[0007] Preferably, the top of the sealing groove is located inside the waterproof groove, and the top of the sealing groove is in contact with the inner wall of the waterproof groove.

[0008] Preferably, the roughened area on the top of the concrete wall A corresponds to the groove.

[0009] This utility model has the following beneficial effects: The trapezoidal interlocking design of the groove and protrusion at the connection between concrete wall A and concrete wall B significantly enhances the bonding and sealing of the upper and lower walls, blocking the seepage path at the structural connection. The inner side consists of a multi-layer sealing system composed of sealing groove, waterproof membrane, waterproof groove and asphalt-based sealant. The asphalt-based sealant fills all the tiny gaps, and the nested design of the waterproof groove further prevents water from seeping into the wall attachment position, achieving double anti-seepage inside and out, which is more thorough in protection than the traditional single sealing structure.

Detailed Implementation

[0012] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0013] Example 1: As Figure 1 As shown in Figure 4, this utility model provides the following technical solution: it includes a concrete wall A1 and a concrete wall B11. A groove 2 is provided at the connection between the concrete wall A1 and the concrete wall B11. A protrusion 21 is integrally cast at the bottom of the groove 2. The groove 2 and the protrusion 21 are matched. A steel reinforcement skeleton A22 and a steel reinforcement skeleton B23 are installed inside the concrete wall A1 and the concrete wall B11. A sealing groove 3 is provided on the inner side of the concrete wall B11. A waterproof membrane 31 is attached to the inner side of the concrete wall B11. A waterproof groove 32 is provided on the top of the inner wall of the sealing groove 3. The sealing groove 3, the waterproof membrane 31 and the waterproof groove 32 are filled with asphalt-based sealant 33.

[0014] In this implementation plan: A groove 2 is formed along the height of the concrete wall B11 on the end of the concrete wall A1 near the concrete wall B11. The groove 2 has a trapezoidal cross-section. At the bottom of the concrete wall B11, a protrusion 21 is integrally cast with the concrete wall A1. The protrusion 21 also has a trapezoidal cross-section. The protrusion 21 and the groove 2 are joined in batches during the pouring of the upper and lower concrete walls. This joint between the groove 2 and the protrusion 21 increases the sealing of the sequentially poured concrete wall. Combined with roughening treatment, this enhances the interlocking and bonding forces, thereby increasing the impermeability of the concrete wall after pouring. A steel reinforcement skeleton A22 is pre-installed inside the concrete wall A1, and a steel reinforcement skeleton B23 is pre-installed inside the concrete wall B11. When the steel reinforcement skeletons A22 and B23 are joined vertically, they form a continuous internal skeleton support, ensuring a stable connection between the upper and lower walls. A sealing groove 3 is formed along the height of the concrete wall B11 on the inner side near the interior wall. The sealing groove 3 is a rectangular groove. On the outer side of the sealing groove 3 near the wall surface, a... Waterproof membrane 31 is applied using a full-adhesion method. A waterproof groove 32 is created along the length of the groove on the top inner wall of the sealing groove 3. The waterproof groove 32 is connected to the sealing groove 3. Asphalt-based sealant 33 is filled into the enclosed space formed by the groove cavity of the sealing groove 3, the outer wall of the waterproof membrane 31, and the groove cavity of the waterproof groove 32 using pressure injection. After filling, the surface is smoothed to ensure a tight fit between the sealant and all contact surfaces, free of air bubbles and gaps. This allows the wall structure to be sealed through the trapezoidal interlocking design of the groove 2 and protrusion 21. 3. The waterproof membrane 31, the waterproof groove 32, and the bitumen-based sealant 33 constitute a sealing system. The waterproof membrane 31 first blocks water from contacting the inner wall of the sealing groove 3. The sealant in the waterproof membrane 31 fills all the tiny gaps. The waterproof groove 32 prevents water from seeping at the connection between the bitumen-based sealant 33 and the wall. Through its embedded arc design, it makes it difficult for water to penetrate to the attachment position between the waterproof membrane 31 and the concrete wall B11, completely blocking water from seeping from the inside of the wall panel. This improves the indoor water resistance compared to traditional single sealant.

[0015] The outer surfaces of concrete walls A1 and B11 are provided with a base layer 12, a cement mortar leveling layer 13, and a waterproof coating 14. The base layer 12 is directly attached to the outer surface of concrete walls A1 and B11. The cement mortar leveling layer 13 is applied to the outside of the base layer 12. After the cement mortar leveling layer 13 dries and cures, the waterproof coating 14 is evenly applied to its outside to form an impermeable protective layer on the outer wall side, further blocking water from penetrating from the outside of the wall panel.

[0016] The steel reinforcement cages A22 and B23 are connected by a welded joint 24, and the bottom of the waterproof membrane 31 is attached to the floor slab surface. The steel reinforcement cages A22 and B23 are fixedly connected by the welded joint 24 to ensure the connection strength after the steel reinforcement cages A22 and B23 are joined, thereby improving the overall structural load-bearing capacity of the two concrete wall panels. At the same time, the bottom of the waterproof membrane 31 attached to the inside of the concrete wall B11 extends to the floor slab surface, and the bottom of the waterproof membrane 31 is tightly attached to the floor slab surface, eliminating the gap between the waterproof membrane 31 and the floor slab surface and preventing water from seeping through the gap.

[0017] The top of the sealing groove 3 is located inside the waterproof groove 32, and the top of the sealing groove 3 is in contact with the inner wall of the waterproof groove 32. The top of the sealing groove 3 extends upward and is embedded inside the waterproof groove 32. The outer side wall of the top of the sealing groove 3 is in close contact with the inner side wall of the waterproof groove 32, with no obvious gap between them. This makes the sealing groove 3 and the waterproof groove 32 form a nested sealing structure. With the addition of the bitumen-based sealant 33, the impermeability and sealing performance of the top area of ​​the sealing groove 3 is further improved.

[0018] The roughened area on the top of concrete wall A1 corresponds to the groove 2; the top surface of concrete wall A1 is roughened, and the roughened area corresponds to the position of groove 2. The roughened surface of concrete wall A1 increases the roughness, which can enhance the bonding force with concrete wall B11 and further improve the sealing and seepage prevention effect at the connection between concrete wall A1 and concrete wall B11.

[0019] The working principle of this technical solution is as follows: First, the top of concrete wall A1 corresponding to the groove 2 is roughened to increase surface roughness. Simultaneously, a steel reinforcement skeleton A22 is pre-installed inside concrete wall A1, and a steel reinforcement skeleton B23 is pre-installed inside concrete wall B11. Next, the integrally cast protrusion 21 at the bottom of concrete wall B11 is aligned with the groove 2 of concrete wall A1. A phased casting method is used to achieve a tight connection between the two. Simultaneously, the steel reinforcement skeletons A22 and B23 are fixedly connected using welding joints 24 to form a continuous internal support skeleton. Then, a sealing groove 3 is opened along the height direction on the inner side of concrete wall B11. A waterproof membrane 31 is applied to the outside of the sealing groove 3 using a full-adhesion method to ensure waterproofing. The bottom of the waterproof membrane 31 is tightly bonded to the floor slab to eliminate gaps. Then, a waterproof groove 32 is opened at the top of the inner wall of the sealing groove 3, so that the top of the sealing groove 3 is embedded in the waterproof groove 32 and tightly bonded to the inner wall. Asphalt-based sealant 33 is filled into the closed space formed by the sealing groove 3, the outer wall of the waterproof membrane 31 and the waterproof groove 32 by pressure injection. After filling, the surface is smoothed to ensure that there are no air bubbles or gaps. Finally, the base layer 12 is treated on the outer side of the concrete wall A1 and the concrete wall B11 in sequence. A cement mortar leveling layer 13 is applied to the outside of the base layer 12. After the leveling layer dries and cures, a waterproof coating 14 is evenly applied to form an external wall anti-seepage protective layer, thus completing the construction of the anti-seepage structure of the entire building's concrete wall panel.
