Abstract

This invention provides a damper component for energy dissipation and vibration reduction in building structures, belonging to the field of building structure energy dissipation and vibration reduction technology. It includes damping units corresponding to building surfaces. Each damping unit comprises a main chain damper with mounting seats at both ends, a connecting seat in the middle of the main chain damper, and branch chain dampers spherically hinged between the connecting seat and the mounting seat. These three components form a connecting chain that intersects with the main chain damper. The connecting chain is connected to both ends of the main chain damper via corresponding mounting seats. This damper component for energy dissipation and vibration reduction in building structures uses multiple spherically hinged dampers to form multiple energy dissipation and vibration reduction chains, enabling effective energy dissipation and vibration reduction in multiple directions. Simultaneously, it effectively links these energy dissipation and vibration reduction chains to form a combined support and energy dissipation structure, improving the overall energy dissipation and vibration reduction capacity and the strength of the connection support.

Description

Technical Field

[0001] This invention relates to the field of energy dissipation and vibration reduction technology for building structures, specifically a damper component for energy dissipation and vibration reduction in building structures. Background Technology

[0002] Building structure energy dissipation and vibration reduction refers to the use of specific structural measures designed and installed to reduce the impact of vibration amplitude on the structure under earthquake or other vibration loads. The application of dampers in building structures has allowed people to move beyond the traditional concept of strengthening beams, columns, and walls to improve vibration resistance. By combining the dynamic performance of the structure, it cleverly avoids or reduces the damage to buildings caused by earthquakes and wind.

[0003] Currently, dampers in building structures are generally connected to the wall via lugs and pins. This connection method only allows for longitudinal up-and-down energy dissipation and vibration reduction. While the connection strength meets requirements, the direction of energy dissipation and vibration reduction is relatively singular. For non-longitudinal forces, it is not only difficult to effectively dissipate energy and reduce vibration, but it is also prone to damage due to stress, affecting its energy dissipation and vibration reduction capabilities. This limits the effective application of dampers in building structures in coastal areas with frequent strong winds, thus hindering the improvement of the stability and safety of building structures in such areas. Secondly, when a building vibrates, the single connection between the damper and the wall via lugs and pins means the stress point is concentrated at the connection point. This connection method is prone to damage under significant vibrations. Finally, multi-directional movable damper connection methods are not currently used because the connection strength between the damper and the wall is insufficient, significantly reducing the damper's performance. Summary of the Invention

[0004] This invention provides a damper component for energy dissipation and vibration reduction in building structures, in order to solve the problems in related technologies where dampers cannot be fully and effectively utilized due to the single direction of force reduction and the connection points being easily damaged by excessive force and insufficient connection strength.

[0005] This invention provides a damper component for energy dissipation and vibration reduction in building structures. The damper component includes damping units corresponding to the building surfaces. The building structure has four surfaces (front, back, left, and right). The damping units are respectively installed on the corresponding surfaces. Each damping unit includes a main chain damper with mounting seats at both ends, which are ball-hinged to the building structure. A connecting seat is provided in the middle of the main chain damper. A branch damper is ball-hinged between the connecting seat and the mounting seat. One branch damper is located above the main chain damper, and the other... One damper is located below, and two branch dampers are located on both sides of the associated seat. The three of them form a connecting chain 1 that intersects with the main chain damper. The connecting chain 1 is connected to both ends of the main chain damper through the corresponding mounting seat. A branch damper 2 is provided between two adjacent damping units. One end of the branch damper 2 is ball-hinged with the associated seat in one damping unit, and the other end is ball-hinged with the associated seat in another damping unit. The branch damper 2 and the corresponding associated seat are combined to form a connecting chain 2 that connects the main chain dampers in adjacent damping units together.

[0006] In one possible implementation, reinforcing seats are provided on both the upper and lower sides of the associated seat, and the reinforcing seats are fixedly connected to the building structure. Symmetrically distributed branch dampers are provided between the reinforcing seats and the associated seats. One end of the branch damper is ball-hinged to the reinforcing seat, and the other end is ball-hinged to the associated seat.

[0007] In one possible implementation, the two branch dampers within the damping unit are both inclined and distributed parallel to each other.

[0008] In one possible implementation, the symmetrical branched dampers are arranged in a trumpet shape.

[0009] In one possible implementation, the hinge point of the second branch damper with the associated seat is on the same horizontal plane as the hinge point of the main chain damper.

[0010] The above-described one or more technical solutions in the embodiments of the present invention have at least one of the following technical effects:

[0011] 1. According to an embodiment of the present invention, a damper component for energy dissipation and vibration reduction in building structures is provided. Multiple dampers with ball joints are used to form multiple energy dissipation and vibration reduction chains, which can effectively dissipate energy and reduce vibration in multiple directions. At the same time, the energy dissipation and vibration reduction chains are effectively linked together to form a structure for joint support and energy dissipation and vibration reduction, thereby improving the overall energy dissipation and vibration reduction capacity and connection support strength. The connecting chain intersects with the main chain damper and is connected to the main chain damper through the mounting base, which improves the support strength of the main chain damper and reduces the stress at the connection points at both ends of the main chain damper. The stress is changed from the original situation where the connection points at both ends of the damper are subjected to stress to the entire main chain damper, thereby ensuring the connection support strength of the main chain damper and effectively avoiding damage caused by excessive stress at the connection points of the damper.

[0012] 2. According to an embodiment of the present invention, a damper component for energy dissipation and vibration reduction of building structures is provided. A branch damper is combined with an associated seat to form a connecting chain that intersects with the main chain damper. The connecting chain is connected to both ends of the main chain damper through mounting seats on the left and right sides, so that the main chain damper is subjected to force as a whole. Compared with the original force at the connection points of the damper ends, this not only improves the connection support strength of the main chain damper, but also effectively avoids damage caused by excessive force at the connection points.

[0013] 3. According to an embodiment of the present invention, a damper component for energy dissipation and vibration reduction of building structures is provided, wherein the branch damper two connects the main chain dampers in adjacent damping units together through an associated seat, thereby further improving the strength of its connection support.

[0014] 4. According to an embodiment of the present invention, a damper component for energy dissipation and vibration reduction of building structures is provided, wherein the reinforcing seat and the three-part chain damper are combined together to form a four-level energy dissipation and vibration reduction chain, which further improves the overall energy dissipation and vibration reduction capacity on the one hand, and further improves the connection support strength of the main chain damper on the other hand.

[0019] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] Please see Figures 1-3 A damper component for energy dissipation and vibration reduction in building structures includes damping units corresponding one-to-one with the building surfaces. The building structure has four surfaces: front, back, left, and right. Four damping units are installed on the four base surfaces during construction. Each base surface consists of an upper base surface and a lower base surface. The damping units are installed between the upper and lower base surfaces. For clarity, it is proposed that the orientation of each of the four base surfaces is defined by its corresponding viewing angle as the orthographic viewpoint. That is, the front base surface corresponds to the orthographic viewpoint, and its six orientations (up, down, left, right, front, and back) are directly defined by the orthographic viewpoint. The left base surface corresponds to the left viewing angle, and the left base surface corresponds to the left viewing angle. The viewing angle is converted to a frontal viewing angle to define its six directions: up, down, left, right, front, and back. Similarly, the right-side viewing angle corresponding to the right base surface is converted to a frontal viewing angle to locate its orientation, and the rear-side viewing angle corresponding to the rear base surface is converted to a frontal viewing angle to define its orientation. The damping unit includes a horizontally arranged main chain damper 2. The left and right ends of the main chain damper 2 are respectively ball-jointed with mounting seats 1. The right mounting seat 1 is fixedly installed on the upper base surface, and the left mounting seat 1 is fixedly installed on the lower base surface, thus forming a multi-directional first-stage energy dissipation and vibration reduction chain. A connecting seat 3 is fixedly installed in the middle of the main chain damper 2. A branch damper 4 is ball-jointed between the mounting seat 1 and the connecting seat 3. Figure 2As shown, the branch damper 4 between the connecting seat 3 and the right mounting seat 1 is located above the main chain damper 2, and the branch damper 4 between the connecting seat 3 and the left mounting seat 1 is located below the main chain damper 2. The connecting seat 3 and the branch dampers 4 on both sides are combined to form a connecting chain that intersects with the main chain damper 2. This connecting chain serves as a multi-directional secondary energy dissipation and vibration reduction chain, which, combined with the primary energy dissipation and vibration reduction chain, enhances the overall structure's energy dissipation and vibration reduction capabilities. It also connects to both ends of the main chain damper 2 through the mounting seats 1 on both sides, acting as a reinforcing chain to improve the overall connection support strength. By dispersing the force, it reduces the connection strength of the main chain damper 2. The stress intensity at the connection point allows the main chain damper 2 to bear the force as a whole, improving the connection support strength of the main chain damper 2. At the same time, it avoids damage caused by excessive stress at the connection point. Compared with the existing lug pin connection, this invention can effectively dissipate energy and reduce vibration in multiple directions. Therefore, it can be fully and effectively applied in building structures in areas with frequent strong winds, such as coastal areas, effectively improving the stability and safety of building structures in such areas. At the same time, it solves the drawback of insufficient connection strength of a single ball hinge damper, which reduces the performance of the damper. The force is changed from the connection point at both ends of the damper to the entire main chain damper 2 bearing the force, thereby ensuring the connection support strength of the main chain damper 2.

[0021] See 1 and Figure 3 The two branch dampers 4 within the damping unit are both inclined and parallel to each other, such as Figure 3 As shown, the branch dampers 4 are all inclined with the left side lower than the right side. This arrangement is designed to enhance the energy dissipation and vibration reduction capabilities against downward forces. When the force acts downward through the upper base body onto the mounting base 1 on the right side, the downward force is dispersed by the branch dampers 4 on the right side and forms a reverse force through the connecting seat 3, acting on the main chain damper 2 to form a reverse suppressive force, further improving the support strength of the main chain damper 2. Figure 3 As shown, the downward force acts on the right end connection of the main chain damper 2 through the mounting seat 1 on the right. At the same time, the branch damper 4 on the right disperses the downward force and acts on the connecting seat 3. The force is transmitted to the main chain damper 2 through the connecting seat 3, generating a force opposite to the downward force to increase the support strength of the main chain damper 2. Meanwhile, when the right end connection of the main chain damper 2 is subjected to downward rotation, the force is transmitted to the branch damper 4 on the left through the connecting seat 3. The branch damper 4 generates a reaction force to suppress the main chain damper 2, further improving the support strength of the main chain damper 2.

[0022] See Figure 1 and Figure 2 A branch damper 5 is provided between adjacent damping units along the circumference of the building structure. Both ends of the branch damper 5 are respectively ball-hinged to the associated seat 3 in the damping unit. Figure 2 As shown, one end of the branch damper 2 5 is ball-jointed with the associated seat 3 in one of the damping units, and the other end is ball-jointed with the associated seat 3 in another damping unit, thus forming a multi-directional three-stage energy dissipation and vibration reduction chain. This three-stage energy dissipation and vibration reduction chain not only improves the overall energy dissipation capacity of the structure by combining with the first-stage and second-stage energy dissipation and vibration reduction chains, but also connects the main chain dampers 2 in adjacent damping units, further improving the strength of their connection support.

[0023] See Figure 1 and Figure 3 The upper and lower sides of the associated seat 3 are provided with reinforcing seats 6. The upper reinforcing seat 6 is fixedly connected to the upper base surface, and the lower reinforcing seat 6 is fixedly connected to the lower base surface. Symmetrical branched dampers 7 are provided between the reinforcing seat 6 and the associated seat 3. Figure 3 As shown, the symmetrical branch damper 3 7 is closed in a trumpet shape, and one end of the branch damper 3 7 is ball-hinged to the reinforcing seat 6, and the other end is ball-hinged to the associated seat 3, thus forming a multi-directional four-stage energy dissipation and vibration reduction chain. This four-stage energy dissipation and vibration reduction chain, together with the first-stage, second-stage, and third-stage energy dissipation and vibration reduction chains, further improves the energy dissipation and vibration reduction capacity of the overall structure. At the same time, the four-stage energy dissipation and vibration reduction chain connects the main chain damper 2 to the upper base body and the lower base body again, further improving the connection support strength of the main chain damper 2 and further improving the vibration reduction and energy dissipation capacity of the overall structure.
