Abstract
Description
Technical Field
[0001] This utility model relates to the field of building shear wall technology, specifically a lateral force strengthening component for high-rise structures. Background Technology
[0002] With urban development and population growth, high-rise buildings are becoming increasingly common. Due to their height, the lateral deformation and stability of high-rise buildings are particularly prominent under the influence of horizontal forces such as wind loads and earthquakes. Therefore, how to effectively improve the lateral force resistance of high-rise structures has become a key focus for structural engineers. Common lateral force resisting components in high-rise structures mainly include shear walls and frame columns.
[0003] Currently, existing shear wall structures may have limited lateral stiffness when facing large horizontal loads, resulting in large lateral deformation of the structure. Moreover, the connection methods between adjacent shear walls are often not ideal, with insufficient collaborative working ability, and cannot fully utilize the overall lateral force resistance performance. The existing connection methods are simply splicing, and the strength and stability of the connection parts are poor, making it difficult to withstand complex loads. Utility Model Content
[0004] The purpose of this invention is to provide a lateral force-strengthening component for high-rise structures to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. This high-rise structural lateral force strengthening member increases the connection area between shear walls by setting extension steel plates 1 and 2 on shear wall 1 and shear wall 2 respectively.

[0024] 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.
[0025] like Figure 1-5 As shown, this utility model provides a technical solution:
[0026] A lateral force-resisting strengthening member for a high-rise structure includes a shear wall 1 and a shear wall 2, which are arranged side by side. Extended steel plates 3 are symmetrically arranged at both ends of the right side of shear wall 1, and extended steel plates 4 are symmetrically arranged at both ends of the left side of shear wall 2. Side steel plates 7 are arranged on the same side end face of shear wall 1 and shear wall 2, and side steel plates 8 are arranged on the opposite side end face of shear wall 1 and shear wall 2. A plurality of reinforcing ribs 9 are arranged inside shear wall 1 and shear wall 2, and the two ends of the reinforcing ribs 9 are fixedly connected to the side steel plates 7 and 8.
[0027] In this embodiment, several reinforcing ribs 9 are provided inside shear wall 1 and shear wall 2, and the two ends of the reinforcing ribs 9 are fixedly connected to side steel plate 2 7 and side steel plate 8. When the structure is under stress, the load can be evenly distributed to the side steel plates, avoiding local stress concentration. For example, when the building is subjected to uneven wind load or seismic force, the reinforcing ribs 9 can distribute the concentrated load to various parts, making the stress on the structure more uniform, thereby improving the load-bearing capacity and stability of the structure.
[0028] like Figure 2 and Figure 3As shown, the outer end face of the first extension steel plate 3 abuts against the inner end face of the second extension steel plate 4. An assembly mechanism is provided between the first extension steel plate 3 and the second extension steel plate 4. The assembly mechanism includes a T-slot 5. The T-slot 5 is symmetrically provided on the outer end face of the first extension steel plate 3 and the inner end face of the second extension steel plate 4. An I-beam steel plate 6 is vertically provided between the two T-slots 5. The outer end face of the second extension steel plate 4 is on the same horizontal line as the outer end faces of the first shear wall 1 and the second shear wall 2. A casting cavity 13 is provided between the second side steel plate 7 and the two first extension steel plates 3.
[0029] In this embodiment, by setting extension steel plates 3 and 4 on shear wall 1 and shear wall 2 respectively, the connection area between the shear walls is increased. When the high-rise building is subjected to horizontal loads, the extension steel plates can work together with the shear walls to bear the load, effectively improving the lateral stiffness of the overall structure and reducing the lateral deformation of the structure under horizontal force. For example, in strong wind weather, the building is subjected to a large wind load. The presence of the extension steel plates can enhance the resistance of the structure and keep the lateral displacement of the building within a safe range. Furthermore, the I-beams 6 set between the extension steel plates are connected by tenon and mortise joints with the I-beams formed by the T-slots 5, further enhancing the integrity and lateral stiffness of the structure. The I-beams 6 can provide additional support in the horizontal direction, making the structure more stable when subjected to horizontal loads.
[0030] like Figure 1 and Figure 5 As shown, a fixing mechanism is provided between the first extension steel plate 3, the second extension steel plate 4 and the assembly mechanism. The fixing mechanism includes bolt holes 10 and 11. Several bolt holes 10 are regularly arranged on the first extension steel plate 3 and the second extension steel plate 4. Several bolt holes 11 are arranged sequentially from top to bottom in the middle of the I-beam steel plate 6. A bolt 12 is provided between the bolt holes 10 and the bolt holes 11.
[0031] In this embodiment, the bolts 12 in the fixing mechanism pass through the bolt holes on the extension steel plate and the I-beam 6, firmly connecting them together, further enhancing the connection strength between the shear walls, enabling them to bear the load as a whole, and improving the collaborative working ability of the structure.
[0032] Working Principle: When a high-rise building is subjected to horizontal loads, shear wall 1 and shear wall 2, as the main lateral force resisting components, bear the load first. The installation of extension steel plate 3 and extension steel plate 4 increases the connection area between the shear walls, improving the overall lateral stiffness. In the assembly mechanism, the T-slots 5 symmetrically arranged on extension steel plate 3 and extension steel plate 4 form an "I" shaped groove. The I-beam steel plate 6 is engaged with the "I" shaped groove. This engagement method is a mortise and tenon connection. In this device, the "I" shaped groove is equivalent to a mortise, and the I-beam steel plate 6 is equivalent to a tenon. When the I-beam steel plate 6 is engaged with the "I" shaped groove, a tight fit is formed between the two, which can effectively limit their mutual restraint. The relative displacement and rotation between the shear walls not only enhances the tightness of the connection, enabling shear wall 1 and shear wall 2 to work together better, but also distributes the load evenly between the extension steel plate 3, extension steel plate 4, shear wall 1 and shear wall 2 when bearing load, avoiding stress concentration. During load transfer, the stiffener 9 can evenly distribute the load to the side steel plate 8 and side steel plate 7, avoiding local stress concentration. At the same time, the bolts 12 in the fixing mechanism pass through bolt holes 10 and 11, firmly connecting the extension steel plate and the I-beam 6 together, further ensuring the stability of the entire structure during the stress process.
[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
