Description

Technical Field

[0001] This utility model relates to the field of shear wall technology, specifically to a prefabricated steel plate shear wall. Background Technology

[0002] Against the backdrop of the construction industry's transformation and upgrading towards green and industrialization, the innovation and optimization of building structural systems have become the core driving force for the industry's development. Traditional reinforced concrete shear walls, with their good load-bearing capacity and seismic performance, are widely used in high-rise buildings. Steel plate shear walls, as a new type of lateral force resisting component, are gradually becoming a research hotspot in the field of high-rise building structures due to their lightweight, high strength, good ductility, and superior seismic performance.

[0003] However, existing prefabricated steel plate shear walls still have some problems in use:

[0004] First, existing steel plate shear walls are generally assembled by welding, which is not stable enough. Second, disassembly is also quite troublesome, thus reducing the ease of assembly and reusability of steel plate shear walls.

[0005] Secondly, traditional steel plate shear walls are usually constructed of a single steel plate and lack a sandwich structure design. A single steel plate cannot simultaneously meet the comprehensive requirements of modern buildings for safety, energy conservation and comfort, which greatly reduces the actual performance of the shear wall. Utility Model Content

[0006] To address the problems of inconvenient assembly and low performance in actual use of existing steel plate shear walls, the purpose of this utility model is to provide a prefabricated steel plate shear wall.

A groove is opened parallel to one side of the first steel plate, and a positioning pin is movably inserted into the groove and the clamping rod. An anti-loosening bolt is threadedly connected between the positioning pin and the groove.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Figure 1-5 As shown, this utility model provides a prefabricated steel plate shear wall, including a first steel plate 1, a second steel plate 4 movably disposed on one side of the first steel plate 1, and a third steel plate 5 movably disposed on one side of the second steel plate 4. The first steel plate 1, the second steel plate 4, and the third steel plate 5 are combined to form the main body of the shear wall. The first steel plate 1, the second steel plate 4, and the third steel plate 5 are all provided with a sandwich assembly 3 inside. The sandwich assembly 3 improves the performance of the steel plate shear wall. A connecting assembly 2 is provided between the first steel plate 1 and the second steel plate 4 and the third steel plate 5. The connecting assembly 2 realizes the rapid assembly of the shear wall.

[0021] The connecting component 2 includes parallel clamping rods 26, which are fixedly installed on one side of the second steel plate 4. The first steel plate 1 has a groove 21 on one side that works with the clamping rods 26. The clamping rods 26 and grooves 21 are movably engaged. The engagement design of the clamping rods 26 and grooves 21 provides initial positioning and connection for the first steel plate 1 and the second steel plate 4. During assembly, the steel plates can be quickly aligned, simplifying the installation process. Compared with the complex positioning before traditional welding, it can improve assembly efficiency.

[0022] The clamping rod 26 is a rubber sealing rod, and the clamping groove 21 is a sealing groove. The rubber sealing rod and the sealing groove cooperate to connect the steel plates while effectively preventing rainwater and moisture from entering the interior of the steel plates, thus avoiding the failure of the sandwich assembly 3 due to moisture. A groove 22 is provided parallel to one side of the first steel plate 1. A positioning pin 23 is movably inserted into the groove 22 and the clamping rod 26. A plurality of positioning through holes 25 are provided on one side of the clamping rod 26 to cooperate with the positioning pin 23. The positioning pin 23 is movably inserted into the positioning through holes 25. The outer surface of the positioning pin 23 is matched with the inner wall shape of the positioning through hole 25. The positioning pin 23 is inserted into the groove 22 and the positioning through hole 25 to perform secondary positioning and reinforcement of the clamped steel plates, preventing the clamping rod 26 from sliding or shifting in the clamping groove 21, and enhancing the connection strength and stability between the steel plates.

[0023] The groove 22 is a magnetic groove, and the positioning pin 23 is a magnetic rod. The positioning pin 23 is magnetically connected to the groove 22, and the magnetic groove is magnetically connected to the magnetic rod. When installing the positioning pin 23, it can be automatically aligned by magnetic force, which further simplifies the installation operation and saves installation time. At the same time, the magnetic attraction can help the positioning pin 23 remain stable and prevent it from falling or shifting during installation, thus improving the accuracy and efficiency of assembly. The positioning pin 23 and the groove 22 are connected by a common threaded anti-loosening bolt 24. The anti-loosening bolt 24 is threaded to the positioning pin 23 and the groove 22, providing anti-loosening protection for the connecting component 2. Even under long-term vibration, earthquake and other dynamic loads, it can effectively prevent the positioning pin 23 from loosening or falling off. This connection method breaks through the limitations of traditional welding process and significantly improves the assembly convenience and reusability of steel plate shear walls.

[0024] The sandwich assembly 3 includes a concrete sandwich 31, one side of which is fixedly connected to the inner wall of the first steel plate 1. The concrete sandwich 31 is made of reinforced concrete. With its high strength and rigidity, the concrete sandwich 31 works in conjunction with the steel plate to improve the load-bearing capacity and lateral displacement resistance of the shear wall, thereby enhancing structural safety. A thermal insulation sandwich 32 is fixedly connected to one side of the concrete sandwich 31. The thermal insulation sandwich 32 is made of materials such as rock wool, extruded polystyrene board, and polyurethane. The thermal insulation sandwich 32 can effectively block heat transfer, reduce building energy consumption, and meet energy-saving requirements.

[0025] Furthermore, a damping interlayer 33 is fixedly connected to the side of the thermal insulation interlayer 32 facing away from the concrete interlayer 31. The damping interlayer 33 is made of viscoelastic damping material, such as high-damping rubber, which consumes energy through intermolecular friction under vibration load, thereby reducing the vibration amplitude of the wall. The damping interlayer 33 can consume energy during earthquakes or vibrations, reduce the vibration amplitude of the structure, and improve seismic performance. A sound-absorbing interlayer 34 is fixedly connected to the side of the damping interlayer 33 away from the thermal insulation interlayer 32, and the side of the sound-absorbing interlayer 34 facing away from the damping interlayer 33 is fixedly connected to the inner wall of the first steel plate 1. The sound-absorbing interlayer 34 is made of sound-absorbing cotton, which can absorb indoor and outdoor noise, improve the acoustic environment of the building, and enhance the comfort of living or using it. The internal structures of multiple sets of the interlayer components 3 are set up with the same configuration, and the setting of multiple sets of interlayer components 3 with the same structure ensures that the performance of each part of the entire shear wall is consistent, ensuring the stability and uniformity of the building function.

[0026] Working principle: In the installation process of prefabricated steel plate shear wall, the connecting component 2 plays a key role. First, the clamping rod 26, which is fixedly installed parallel to one side of the second steel plate 4, is inserted into the corresponding clamping groove 21 opened parallel to one side of the first steel plate 1. The connection between the clamping rod 26 and the clamping groove 21 is initially realized by the movable engagement of the clamping rod 26 and the clamping groove 21. Since the clamping rod 26 is a rubber sealing rod and the clamping groove 21 is a sealing groove, this structural design can effectively ensure the sealing of the connection part.

[0027] Meanwhile, multiple positioning through holes 25 on one side of the clamping rod 26 are aligned with the groove 22 on one side of the first steel plate 1. The positioning pin 23 is inserted into the positioning through holes 25 and the groove 22 in sequence. The groove 22 is used as a magnetic groove and the positioning pin 23 is used as a magnetic rod to fix the positioning pin 23 initially. The outer surface of the positioning pin 23 matches the inner wall shape of the positioning through hole 25, further ensuring the accuracy of positioning.

[0028] Subsequently, the positioning pin 23 is reinforced by threading an anti-loosening bolt 24 between the positioning pin 23 and the groove 22 to prevent it from loosening, thereby completing the firm connection between the first steel plate 1 and the second steel plate 4.

[0029] Similarly, the third steel plate 5 is connected to the second steel plate 4 using the same connection method.

[0030] In terms of the overall structure's functionality, the sandwich component 3 plays an important role. Taking the sandwich component 3 inside the first steel plate 1 as an example, the concrete sandwich 31 is fixedly connected to the inner wall of the first steel plate 1, providing the wall with basic strength and stability.

[0031] The thermal insulation layer 32 on one side of the concrete interlayer 31 can effectively prevent the transfer of heat and achieve a good thermal insulation effect. The damping interlayer 33 on the back side of the thermal insulation layer 32 can absorb and consume the vibration energy transmitted from the outside, and reduce the shaking of the wall when it is subjected to vibration.

[0032] The sound-absorbing interlayer 34 on the side of the damping interlayer 33 away from the thermal insulation interlayer 32 can absorb external noise and reduce the propagation of sound, thereby achieving the performance of the entire prefabricated steel plate shear wall in terms of strength, thermal insulation, vibration reduction and noise reduction.

[0033] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
