TECHNICAL FIELD
[0001] The utility model relates to the technical field of building engineering, concretely to a basement shear wall waterproof structure. BACKGROUND
[0002] In the field of building engineering, as an important part of the building, the waterproof performance of the shear wall of the basement is directly related to the use function, durability of the basement and the safety of the whole building. With the acceleration of urbanization, the application scenarios of the basement are increasingly widespread, such as underground parking lot, underground shopping mall, underground warehouse, etc. The waterproof requirement is also higher and higher. However, the traditional basement shear wall waterproof technology has many limitations. In terms of wall structure, some traditional walls only use single concrete or masonry structure, which has poor anti-cracking performance. Under the complex geological environment of the basement and the long-term action of underground water pressure, cracks are easily produced, thus providing a channel for the seepage of underground water. For example, when the underground water level fluctuates seasonally or changes due to surrounding engineering construction, the water pressure borne by the wall changes greatly, and ordinary walls are difficult to effectively cope with such pressure changes, and cracks are easily produced to cause seepage. In terms of waterproof treatment, the traditional waterproof layer is relatively simple, and single waterproof roll material or waterproof coating is directly brushed on the wall surface. Such single waterproof layer is easily damaged due to aging, wear and tear or poor adhesion with the wall base layer in the long-term use process. For example, during the construction process of the basement, if the waterproof layer is damaged by the collision of construction machinery or subsequent maintenance and modification, it is difficult to repair and restore the original waterproof effect. At the same time, the traditional waterproof technology is not fine enough in the connection between the wall and other structural parts. These parts are often the weak link of waterproofing and are easily damaged due to the cracks caused by structural deformation or temperature changes. In addition, the traditional basement shear wall lacks effective structural reinforcement and protection measures. When bearing large lateral soil pressure and underground water pressure, the stability of the wall is difficult to guarantee. Once the wall deforms or displaces, not only the waterproof layer is damaged, but also the seepage problem is aggravated. Moreover, in the use process of the basement, the wall is easily damaged by external factors, further reducing the waterproof performance, increasing the maintenance cost and the safety hazard of the building.
[0003] However, the prior art has the following problems in actual use:
[0004] When the overall device is used, it cannot effectively prevent the seepage of underground water from the wall surface and the connection, the wall has poor anti-cracking performance and lacks effective reinforcement, is easily damaged by external factors, cannot prevent mechanical damage and external impact during construction and use, increases the service life of the waterproof structure, and improves the seepage risk and maintenance cost caused by wall damage. SUMMARY

The wall has poor crack resistance and lacks effective reinforcement, making it susceptible to damage from external factors. It cannot prevent mechanical damage and external impact during construction and use, which increases the service life of the waterproof structure and raises the risk of leakage and maintenance costs due to wall damage.

Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0026] Please see Figures 1 to 4 This utility model embodiment provides a waterproof structure for basement shear walls, which is applied in building engineering scenarios. In this embodiment, the waterproof structure of the shear wall is improved to give it the advantage of waterproofing.
[0027] Example 1:
[0028] Please see Figures 1 to 4 This utility model provides a technical solution: a waterproof structure for a basement shear wall, including a wall 1, a waterproof layer 2 bonded to the outer wall of the wall 1, a reinforcing plate 3 fixedly installed inside the wall 1, a brick slab 8 fixedly installed inside the wall 1, a cement board 9 fixedly connected to one side of the brick slab 8, an insulation layer 10 snapped onto the inner wall of the wall 1, a through pin 11 inserted into the outer wall of the waterproof layer 2, the through pin 11 passing through the interior of the waterproof layer 2 and being inserted into the outer wall of the wall 1, a fixing frame 12 welded inside the reinforcing plate 3, and a wire mesh 13 welded inside the fixing frame 12. Therefore, through the brick slab 8, the waterproof structure is reinforced with a waterproof layer 10. The internal structure of the wall 1 is uniformly distributed and tightly arranged. High-strength cement mortar is used between the bricks and slabs 8 to ensure sufficient load-bearing capacity and stability. The interface between the cement board 9 and the bricks and slabs 8 is roughened to enhance the adhesion between them. The cement board 9 has a moderate thickness, further enhancing the overall strength of the wall 1 and providing a flat installation base for the insulation layer 10. The insulation layer 10 uses high-quality insulation materials, such as polystyrene foam board, which is clipped into grooves on the inner wall of the wall 1. The depth of the grooves matches the thickness of the insulation layer 10, allowing the insulation layer 10 to be securely installed within the wall 1. To effectively reduce heat transfer between the basement's interior and exterior environments and improve its insulation performance, the through-pin 11 is made of corrosion-resistant metal, such as stainless steel, with a diameter matching the diameter of the insertion holes on the waterproof layer 2 and wall 1. After insertion into the waterproof layer 2 and wall 1, both ends of the through-pin 11 are sealed with sealant to prevent moisture from seeping in along the through-pin 11. The waterproof layer 2 uses a high-performance waterproof membrane, such as SBS modified bitumen waterproof membrane, and its bonding to the outer wall of wall 1 uses a special waterproof adhesive, ensuring the bonding area meets the specified standards and guarantees a tight connection between the waterproof layer 2 and wall 1. With no leaks or gaps, it maintains excellent waterproof performance even in long-term contact with groundwater. The fixing frame 12 has a grid structure and is welded to key stress-bearing parts inside the reinforcing plate 3. It adopts a continuous welding process, with full and defect-free welds. The wire diameter and grid size of the wire mesh 13 are designed according to the stress requirements of the wall 1. The welding points of the wire mesh 13 and the fixing frame 12 are evenly distributed, so that the reinforcing plate 3 is subjected to uniform stress. It can effectively resist groundwater pressure, soil lateral pressure, and stress caused by temperature changes, prevent cracks or deformation in the wall 1, and ensure the integrity and stability of the waterproof structure.
[0029] Example 2:
[0030] To further enhance the waterproofing effect and effectively prevent moisture from seeping in from the joints of other structures, a sealing frame 4, a steel plate 5, and a bearing seat 6 are installed.
[0031] A sealing frame 4 is provided on the outer wall of wall 1. A steel plate 5 is provided on one side of wall 1, and a bearing seat 6 is welded to one side of steel plate 5. A waterproof strip 14 is bonded to the inner wall of the sealing frame 4. The inner wall of the waterproof strip 14 is bonded to the outer wall of the insulation layer 10. One side of steel plate 5 is fixedly installed to one side of insulation layer 10. A steel bar 15 is fixedly installed inside steel plate 5. A triangular block 16 is welded to the inner wall of bearing seat 6, and a positioning ring 17 is fixedly installed inside bearing seat 6. Therefore, because the waterproof strip 14 is made of rubber and its width is adapted to the width of the inner wall of the sealing frame 4, and the bonding of the waterproof strip 14 to the inner wall of the sealing frame 4 and the outer wall of the insulation layer 10 uses high-strength rubber adhesive, it is ensured that the waterproof strip 14 can still maintain good sealing performance when different structural components undergo slight displacement due to temperature changes or settlement, effectively preventing moisture from entering through the connection between wall 1 and other structures. To prevent leakage, the reinforcing bars 15 are distributed in a crisscross pattern inside the steel plate 5. The diameter and spacing of the reinforcing bars 15 are determined according to the stress calculation of the basement structure, which enhances the load-bearing capacity and deformation resistance of the steel plate 5, enabling it to better assist the wall 1 in bearing external loads and ensuring the safety of the basement structure. The triangular blocks 16 are symmetrically distributed on the inner wall of the bearing seat 6. The triangular blocks 16 are made of high-strength alloy steel and have exquisite welding technology. The weld strength is higher than the strength of the bearing seat 6 itself, which can provide stable support and positioning for the structure or equipment it supports. The inner diameter of the positioning ring 17 matches the outer diameter of the connecting parts of the structure or equipment it supports. The positioning ring 17 is fixed inside the bearing seat 6 by welding or bolting to ensure the accuracy and stability of the installation position of the supported parts and to ensure the reliability and coordination of the connection of each part in the entire basement structure system.
[0032] Example 3:
[0033] To enhance overall stability and sealing, and to prevent the waterproof structure from failing due to localized damage, a protective partition 7 is installed.
[0034] Protective partitions 7 are provided on both sides of the wall 1. Hot melt adhesive 18 is bonded to the outer wall of the protective partition 7. One side of the hot melt adhesive 18 is bonded to both sides of the wall 1. Therefore, by uniformly applying the hot melt adhesive 18 to the outer wall of the protective partition 7 with a moderate coating thickness, good adhesion performance can be maintained under different temperature and humidity environments. The protective partition 7 is made of rigid plastic board or fiber reinforced board, which has a certain strength and toughness. It can effectively prevent the wall 1 from being damaged by mechanical damage such as collision and scratch during construction. At the same time, it can also resist a certain degree of external impact during use in the basement, protecting the integrity of the wall 1 and the internal waterproof structure and extending the service life of the waterproof structure.
[0035] In this invention, the working steps of the device are as follows:
[0036] First, construct the basic framework of wall 1. Lay bricks and slabs 8 in the designated positions according to the design requirements. Use high-quality cement mortar to ensure a strong bond between the bricks and slabs 8, guaranteeing the basic shape and initial strength of wall 1. After the bricks and slabs 8 are laid, install a cement board 9 on one side. The interface between the cement board 9 and the bricks and slabs 8 is pre-cleaned and roughened, then adhesive is applied and the boards are tightly bonded together, forming a unified whole. This enhances the strength and flatness of wall 1, providing a good foundation for subsequent construction. Install the insulation layer 10 in the grooves on the inner wall of wall 1. The insulation layer 10 material, such as polystyrene foam board, is cut according to the dimensions of the grooves to ensure a tight fit without obvious gaps. During installation, care is taken to avoid deformation or damage to the insulation layer 10 to ensure its insulation performance is not affected. Then, apply a waterproof layer 2 material, such as SBS... Modified bitumen waterproof membrane is laid on the outer wall of wall 1. First, a layer of special waterproof adhesive is evenly applied to the outer wall of wall 1. Then, the waterproof layer 2 membrane is unfolded and gradually laid on wall 1. Air between the membrane and wall 1 is removed using tools such as a roller or scraper to ensure a tight bond. During the laying of waterproof layer 2, through-pins 11 are inserted at certain intervals. The through-pins 11 pass through the waterproof layer 2 and into the outer wall of wall 1. After insertion, both ends of the through-pins 11 are sealed to prevent moisture from seeping in along the through-pins 11. To enhance the connection stability between the waterproof layer 2 and the wall 1, a reinforcing plate 3 is installed inside the wall 1 and placed in a predetermined position. Its internal fixing frame 12 is welded to the internal structure of the wall 1. The fixing frame 12 adopts a mesh structure, welded at key stress-bearing areas with continuous and full welds. After the fixing frame 12 is welded, a wire mesh 13 is welded inside it. The wire diameter and mesh size of the wire mesh 13 are determined according to the stress requirements of the wall 1, ensuring that the reinforcing plate 3 effectively enhances the structural strength of the wall 1 and resists... To withstand groundwater pressure and soil lateral pressure, the sealing frame 4 is installed on the outer wall of wall 1. The sealing frame 4 is made of aluminum alloy and is custom-made according to the dimensions of wall 1. During installation, rubber adhesive is applied to the inner wall of the sealing frame 4, and then the waterproof tape 14 is adhered to the inner wall of the sealing frame 4. The waterproof tape 14 is made of rubber and its width is adapted to the inner wall of the sealing frame 4. The sealing frame 4 is then installed on wall 1, ensuring a tight bond between the inner wall of the waterproof tape 14 and the outer wall of the insulation layer 10, thus ensuring a waterproof seal at the connection between wall 1 and other structural components. The steel plate 5 is installed on one side of the wall 1. The steel plate 5 is connected to the insulation layer 10 using a combination of anchor bolts and adhesive bonding. The anchor bolts are evenly distributed on the connection surface, and the adhesive fills the gaps. Reinforcing bars 15 are installed inside the steel plate 5 according to design requirements. The reinforcing bars 15 are distributed crisscrossingly to enhance the load-bearing capacity of the steel plate 5. A load-bearing seat 6 is welded to one side of the steel plate 5. Triangular blocks 16, made of high-strength alloy steel and symmetrically distributed, are welded to the inner wall of the load-bearing seat 6 to provide stable support and positioning for the structure or equipment it supports.A positioning ring 17 is installed inside the bearing seat 6. The positioning ring 17 is fixed by welding or bolting to ensure the accurate and stable installation position of the supported component. Protective partitions 7 are installed on both sides of the wall 1. The protective partitions 7 are made of rigid plastic board or fiber reinforced board. Hot melt adhesive 18 is evenly applied to the outer wall of the protective partition 7. The hot melt adhesive 18 is a special building hot melt adhesive that is resistant to high temperature and moisture. The coating thickness is moderate. The protective partitions 7 are bonded to both sides of the wall 1 by the hot melt adhesive 18. This ensures that the protective partitions 7 can effectively prevent the wall 1 from being damaged by collisions, scratches and other mechanical damage during construction, and resist a certain degree of external impact during use, protecting the integrity of the wall 1 and its internal waterproof structure.
