[0047] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0048] Embodiment 1, as Figure 1-13 As shown, the present embodiment provides a prefabricated shear wall with a steel structure support, including a first steel structure support 100, the first steel structure support 100 includes a plurality of hollow steel plates 101, the front and rear sides of the hollow steel plates 101 are fixedly connected with a connection frame 102, the plurality of hollow steel plates 101 are fixedly connected to each other through the connection frame 102, the top and bottom of the front and rear sides of the hollow steel plates 101 are fixedly connected with a socket 103, a multilateral plug 104 is fixedly connected inside the socket 103, and an adjustment tube 105 is fixedly connected to one end of the multilateral plug 104.

[0049] A reinforcing plate 108 is fixedly connected to the inner wall of the hollow steel plate 101 . A plurality of mounting holes 110 are formed on the reinforcing plate 108 . The mounting holes 110 are filled with heat-insulating blocks 109 . The heat-insulating blocks 109 are made of polyurethane foam.

[0050] A first reinforcement frame 106 is fixedly connected to the middle end of the front and rear sides of the hollow steel plate 101, and a second reinforcement frame 107 is fixedly connected to the top and bottom of the front and rear sides of the hollow steel plate 101. The first reinforcement frame 106 and the second reinforcement frame 107 are fixedly connected to the surface of the socket 103.

[0051] The hollow steel plate 101 is connected to the second steel structure support 200 through the socket 103, the multilateral plug 104 and the adjusting tube 105, ensuring a firm connection and avoiding structural safety hazards caused by poor connection. The first reinforcement frame 106 and the second reinforcement frame 107 support and reinforce the socket 103 to prevent it from separating from the hollow steel plate 101, and at the same time strengthen the front and rear sides of the hollow steel plate 101.

[0052] A reinforcing plate 108 is arranged inside the hollow steel plate 101. The presence of the reinforcing plate 108 increases the internal rigidity of the hollow steel plate 101, avoids local deformation or instability of the hollow steel plate 101 when subjected to external force, and improves the structural stability of the entire shear wall. The hollow design of the hollow steel plate 101 and the application of the insulation block 109 reduce the dead weight of the first steel structure support 100, which is particularly important for high-rise buildings because it can reduce the load-bearing requirements of the lower structure, while also reducing energy consumption and costs during transportation and hoisting. The material of the insulation block 109 is polyurethane foam. As a high-performance thermal insulation and sound insulation material, polyurethane foam is filled in the mounting hole 110 of the reinforcing plate 108, which can significantly improve the thermal performance and sound insulation effect of the shear wall, creating a more comfortable living and working environment inside the building. Moreover, after flame retardant treatment, the polyurethane foam can provide certain fire protection, delay the spread of fire, buy time for personnel evacuation, and improve the safety of the building.

[0053] It also includes a second steel structure support member 200, which is in multiple numbers and is installed on the front and rear sides of the first steel structure support member 100. The second steel structure support member 200 includes two mounting seats 201, and the two mounting seats 201 are fixedly connected to vertical rods 202 on opposite sides. The surface of the vertical rods 202 is fixedly sleeved with multiple connecting components 203.

[0054] There are several vertical rods 202, which are distributed around the opposite sides of the two mounting seats 201. The connecting component 203 includes an annular rod 2031 fixedly sleeved on the surface of the vertical rod 202. One side of the annular rod 2031 is fixedly connected to a fixing plate 2032, and one side of the fixing plate 2032 is fixedly connected to an adjusting rod 2033. The adjusting rod 2033 extends to the inner cavity of the adjusting tube 105 and is movably connected to its inner wall.

[0055] The two mounting seats 201 are fixedly connected with mounting screws 205 on opposite sides. A slide groove 303 is provided on the cross plate 301. The mounting screw 205 passes through the slide groove 303 and is threadedly sleeved with a limiting nut sleeve 204. The limiting nut sleeve 204 contacts the surface of the cross plate 301 to limit the mounting screw 205.

[0056] The first steel structure support member 100 serves as the core support of the shear wall and cooperates with a plurality of second steel structure support members 200 to ensure the high strength of the wall and optimize the stiffness of the wall through the arrangement of the second steel structure support members 200, thereby forming a more reasonable stress distribution and improving the bearing capacity and seismic performance of the shear wall.

[0057] The first steel structure support 100 is composed of a plurality of hollow steel plates 101 and a connection frame 102. This splicing method and the adjustable design of the second steel structure support 200 are conducive to the modular and standardized production of components, facilitate mass production and rapid on-site assembly, and further improve construction efficiency and quality control.

[0058] By adjusting the distance between the second steel structure support 200 and the first steel structure support 100, shear walls of different thicknesses can be customized on site according to different building requirements and load conditions, which not only ensures the strength and rigidity of the wall, but also increases the flexibility of the design. When making adjustments, the adjusting rod 2033 is slid on the inner wall of the adjusting tube 105, and the adjusting rod 2033 drives the vertical rod 202 to move through the fixing plate 2032 and the annular rod 2031. The vertical rod 202 drives the mounting seat 201 to slide on the opposite side of the horizontal plate 301, and the mounting seat 201 drives the mounting screw 205 to slide inside the slide groove 303. When the second steel structure support 200 is adjusted to the set position, the limiting nut sleeve 204 is screwed on the mounting screw 205, and the limiting nut sleeve 204 is pressed against the horizontal plate 301 to fix the mounting seat 201, thereby achieving the effect of fixing the second steel structure support 200 as a whole.

[0059] The combination of the vertical rod 202 and the connecting assembly 203 provides additional vertical support, and enhances the ability of the shear wall to resist vertical loads, especially when encountering sudden loads such as earthquakes, and can effectively disperse and absorb energy.

[0060] It also includes a transverse fixing mechanism 300 , which is fixedly installed on the upper and lower sides of the first steel structure support member 100 and the second steel structure support member 200 , and the transverse fixing mechanism 300 includes a transverse plate 301 .

[0061] A plurality of first reserved connecting members 302 are fixedly connected to one side of the transverse plate 301 , and the transverse plate 301 is fixedly connected to the connecting frame 102 by bolts.

[0062] The upper and lower sides of the first steel structure support member 100 and the second steel structure support member 200 are fixed by a transverse fixing mechanism 300, which simplifies the on-site installation process, ensures accurate docking between the components, and also facilitates subsequent maintenance and inspection work.

[0063] It also includes a vertical fixing mechanism 400 , which is fixedly installed on the left and right sides of the first steel structure support 100 . The vertical fixing mechanism 400 includes a vertical plate 401 , and a T-shaped plate 402 is fixedly connected to one side of the vertical plate 401 .

[0064] The vertical plate 401 is fixedly connected to the connection frame 102 by bolts. A clamping block 304 is fixedly connected to the bottom of the horizontal plate 301. The clamping block 304 is clamped on the opposite side of the vertical plate 401 and the T-shaped plate 402. A plurality of second reserved connecting members 403 are fixedly connected to one side of the T-shaped plate 402.

[0065] The horizontal plate 301 and the vertical plate 401 together form a closed frame structure, which significantly improves the ability of the shear wall to resist lateral forces and enhances the overall stability and rigidity of the structure.

[0066] It also includes a wrapping reinforcement mechanism 500 , which is fixedly installed twice in front and behind the vertical fixing mechanism 400 and connected to the surface of the second steel structure support 200 . The wrapping reinforcement mechanism 500 includes a surrounding steel belt 501 .

[0067] Support seats 503 are installed on both the left and right sides of the surrounding steel belt 501 , and the support seats 503 are fixedly connected to the surface of the T-shaped plate 402 .

[0068] A plurality of second limiting holes 502 are provided on both sides of the surrounding steel belt 501 , and a first limiting hole 504 is provided on the support seat 503 . The first limiting hole 504 and the second limiting hole 502 are fixedly connected by bolts.

[0069] The surrounding steel belt 501 forms a tight peripheral support system by connecting with the T-plate 402 and the vertical plate 401, which not only increases the lateral stability of the shear wall, but also improves the ability of the shear wall to resist impact and deformation through the high rigidity and toughness of its metal material.

[0070] The three-dimensional frame formed by the first steel structure support 100, the second steel structure support 200 and the transverse fixing mechanism 300 is fixed by the transverse fixing mechanism 300 and the vertical fixing mechanism 400, which not only enhances the stability of the overall structure, but also improves the ability of the shear wall to resist lateral forces, such as earthquakes and strong winds, thereby ensuring the safety of the building.

[0071] During on-site construction, the prefabricated steel structure parts are transported to the site, and then the formwork is installed and the concrete is poured. Compared with traditional cast-in-place shear walls, this reduces on-site wet operations, speeds up the construction progress, and reduces the construction difficulty and cost.

[0072] Through the mutual coordination of all the above structural components, the entire shear wall system can demonstrate excellent stability and strength in the face of complex loads and environmental conditions. Since prefabricated shear walls have high strength and high stiffness characteristics, this shear wall design is particularly suitable for high-rise buildings and buildings in earthquake-prone areas, and can effectively improve the overall stability and safety of the building.
