Description

Technical Field

[0001] This utility model belongs to the field of shear wall technology, specifically relating to a wind-resistant shear wall structure for buildings. Background Technology

[0002] Shear walls, also known as wind-resistant walls, earthquake-resistant walls, or structural walls, are walls in buildings or structures that primarily bear horizontal and vertical loads (gravity) caused by wind or earthquakes, preventing structural shear failure. They are typically made of reinforced concrete. Planar shear walls are used in reinforced concrete frame structures, lift-slab structures, and flat slab systems. To increase the stiffness, strength, and collapse resistance of the structure, reinforced concrete shear walls can be cast-in-place or precast in certain locations.

[0003] Shear walls are typically placed around concrete beams or columns, and are connected to the concrete columns by steel reinforcement. While this type of shear wall has good overall integrity, there are tiny gaps between the shear wall and the beam or column, which can easily lead to water leakage. Therefore, a shear wall structure with better waterproofing has now been designed to solve the problem of water leakage between the shear wall and the concrete column. Utility Model Content

[0004] To address the problems mentioned in the background section, this utility model provides a wind-resistant shear wall structure for buildings, which solves the problem of water leakage between the shear wall and the concrete column.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wind-resistant shear wall structure for buildings, comprising a shear wall body, the shear wall body including an outer wall section, a waterproof section, and an inner wall section. Vertical and horizontal reinforcing bars are provided inside both the outer and inner wall sections. The waterproof section contains a connecting layer, a waterproof layer, and a water-blocking layer. The connecting layer contains a glass fiber layer and a cement-based penetrating crystalline waterproof coating layer. The waterproof layer contains a neoprene rubber layer and a butyl rubber layer. The water-blocking layer contains an asphalt felt layer and a mortar-accelerating layer. The waterproof layer is located in the middle of the waterproof section, and the water-blocking layer is located on both the front and rear sides of the waterproof layer. The connecting layer is located on the outside of the water-blocking layer.

[0006] Preferably, the vertical and horizontal reinforcing bars are connected by welding, and two layers of vertical and horizontal reinforcing bars are provided inside both the outer and inner walls.

[0007] Preferably, the shear wall body, outer wall, waterproofing section and inner wall section are all L-shaped, and the vertical and horizontal reinforcing bars are also L-shaped.

[0008] Preferably, the thickness of the shear wall body is 25cm, the thickness of the outer wall and the inner wall is 10cm, and the thickness of the waterproof part is 5cm.

[0009] Preferably, the thickness of the waterproof layer is 3cm, and the thickness of the connecting layer and the water-blocking layer is 0.5cm.

[0010] Preferably, the diameter of both the vertical and horizontal reinforcing bars is 1 cm, and the two layers of vertical and horizontal reinforcing bars are arranged symmetrically in the front and back of the outer wall and the inner wall.

[0011] Preferably, the connecting layer, the waterproof layer, and the water-blocking layer are connected by adhesive bonding.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] Waterproof and water-blocking layers effectively prevent water from penetrating into the interior of a building through shear walls, especially in humid environments or areas with high groundwater levels. This prevents the walls from becoming damp, moldy, and damaged, thus protecting the structural integrity of the building and extending its service life. Furthermore, by installing waterproof and water-blocking layers, wall damage and repair needs caused by water penetration can be reduced, thereby lowering long-term maintenance and repair costs.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all 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 protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides the following technical solution: a wind-resistant shear wall structure for a building, comprising a shear wall body 1, the shear wall body 1 comprising an outer wall portion 2, a waterproof portion 3, and an inner wall portion 4, both the outer wall portion 2 and the inner wall portion 4 being provided with vertical reinforcing bars 5 and horizontal reinforcing bars 6, the waterproof portion 3 being provided with a connecting layer 7, a waterproof layer 8, and a water-blocking layer 9, the connecting layer 7 being provided with a glass fiber layer and a cement-based penetrating crystalline waterproof coating layer, the waterproof layer 8 being provided with a neoprene rubber layer and a butyl rubber layer, the water-blocking layer 9 being provided with an asphalt felt layer and a mortar-accelerating layer, the waterproof layer 8 being located in the middle of the waterproof portion 3, the water-blocking layer 9 being located on the front and rear sides of the waterproof layer 8, and the connecting layer 7 being located on the outside of the water-blocking layer 9.

[0022] The waterproof layer 8 and water-blocking layer 9 effectively prevent water from penetrating into the building's interior through the shear wall, especially in humid environments or areas with high groundwater levels. This prevents the wall from becoming damp, moldy, and damaged, thus protecting the building's structural integrity and extending its service life. Furthermore, the waterproof layer 8 and water-blocking layer 9 reduce wall damage and repair needs caused by water penetration, thereby lowering long-term maintenance and repair costs. Since the outer wall section 2 and inner wall section 3 are 10cm thick, using an appropriate thickness provides good load-bearing capacity and stiffness, ensuring the safety and stability of the shear wall structure. A shear wall of suitable thickness meets both structural requirements and architectural design and safety regulations. Because the waterproof layer 8 is 3cm thick, it provides better waterproofing. Choosing an appropriate thickness for the waterproof layer 8 ensures waterproofing while avoiding cost waste due to excessive thickness. The vertical reinforcing bars 5 and horizontal reinforcing bars 6 are connected by welding. The welded connection, through large-area fusion, results in high connection strength between the vertical reinforcing bars 5 and the horizontal reinforcing bars 6, effectively improving the seismic performance of the shear wall main body 1. Furthermore, since the shear wall main body 1, outer wall 2, waterproofing section 3, and inner wall 4 are all L-shaped, the L-shaped shear wall structure exhibits excellent overall performance and provides good structural stability. Under horizontal loads, the L-shaped shear wall exhibits small lateral deformation, effectively resisting horizontal forces and enhancing its wind resistance. Since the diameters of the vertical reinforcing bars 5 and the horizontal reinforcing bars 6 are both 1cm, excessively small diameters may lead to insufficient wall stability, while excessively large diameters may increase construction difficulty and cost. Therefore, a reasonable selection of reinforcing bar diameter can balance construction convenience and mechanical performance. The symmetrical arrangement of the two layers of vertical reinforcing bars 5 and horizontal reinforcing bars 6 further ensures the structural stability of the shear wall. The connecting layer 7, waterproofing layer 8, and water-blocking layer 9 are connected by adhesive. The adhesive can penetrate into gaps and holes, forming a good sealing effect and effectively preventing moisture penetration.

[0023] In one aspect of this embodiment, since the vertical reinforcing bars 5 and the horizontal reinforcing bars 6 are connected by welding, the welding connection, through large-area fusion, results in a high connection strength between the vertical reinforcing bars 5 and the horizontal reinforcing bars 6, which can effectively improve the seismic performance of the shear wall body 1. Furthermore, since the shear wall body 1, the outer wall 2, the waterproof part 3, and the inner wall 4 are all L-shaped, the L-shaped shear wall structure has excellent overall performance and can provide good structural stability. Under horizontal loads, the lateral deformation of the L-shaped shear wall is small, which can effectively resist horizontal forces and make the shear wall more resistant to strong winds.

[0024] In one aspect of this embodiment, since the thickness of the outer wall portion 2 and the inner wall portion 3 is 10cm, using an appropriate thickness can provide better load-bearing capacity and stiffness, ensuring the safety and stability of the shear wall structure. A shear wall with an appropriate thickness can meet both the structural needs and the requirements of building design and safety specifications. Since the thickness of the waterproof layer 8 is 3cm, the waterproof layer 8 can provide better waterproofing. Selecting a waterproof layer 8 with an appropriate thickness can ensure the waterproofing effect while avoiding cost waste caused by excessive thickness.

[0025] In one aspect of this embodiment, since the diameters of both the vertical reinforcing bars 5 and the horizontal reinforcing bars 6 are 1 cm, a diameter that is too small may lead to insufficient stability of the wall, while a diameter that is too large may increase the difficulty and cost of construction. Therefore, a reasonable selection of the reinforcing bar diameter can balance the convenience of construction and mechanical performance. The two layers of vertical reinforcing bars 5 and horizontal reinforcing bars 6 are symmetrically arranged, which can further ensure the structural stability of the shear wall. The connecting layer 7, the waterproof layer 8, and the water-blocking layer 9 are connected by adhesive. The adhesive can penetrate into the gaps and holes to form a good sealing effect and effectively prevent water penetration.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
