Description

Technical Field

[0001] This utility model relates to the field of building component technology, and in particular to a building shear damper. Background Technology

[0002] Building shear dampers are devices commonly used in engineering structures such as high-rise buildings and bridges. Their main function is to reduce structural vibration and mitigate vibrations caused by earthquakes or wind, thereby improving the structure's seismic resistance and safety.

[0003] Shear dampers typically consist of two parallel metal plates filled with a damping material (such as a viscous liquid or colloid). When the structure vibrates, the damping material between the parallel metal plates undergoes shear deformation, converting the vibrational energy into heat. However, in existing technologies, shear dampers are rigidly connected to the building walls via metal connectors. This fails to adequately consider the complexity and dynamic characteristics of shear dampers under stress, potentially leading to breakage or failure of the connectors under shear, bending, or torsional forces. Consequently, the damper loses its shear damping function. Therefore, a new building shear damper is proposed to address these issues. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose a building shear damper to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of the present invention provides a building shear damper, including a wall and a connecting layer, wherein the connecting layer is fixedly connected to the opposing surfaces between the walls, and a connecting frame is embedded inside the connecting layer;

[0007] Several steel bars are fixedly connected between the connecting frames, and a filling layer is provided between the connecting frames;

[0008] The connecting frame is connected by connectors, and a connecting plate is fixedly connected to the top of one connector and the bottom of another connector.

[0009] A connecting plate is fixedly connected to the other end face of the connector, a damping layer is fixedly connected between the connecting plates, an inner rib is fixedly connected inside the damping layer, and the end of the inner rib is connected to the connecting plate.

[0010] Preferably, in any of the above schemes, both the connecting layer and the filling layer are concrete layers, and the ends of the connecting frame are pre-embedded in the connecting layer.

[0011] The building shear resistance damper comprises a connecting frame, a reinforcing bar, a filling layer, a connecting piece, a connecting plate, a connecting plate, a damping layer and an inner reinforcing bar.

[0012] Preferably, the connecting frame is made of steel, and the surface of the connecting frame is fixedly connected with the connecting plate.

[0013] The building shear resistance damper comprises a connecting frame, a reinforcing bar, a filling layer, a connecting piece, a connecting plate, a connecting plate, a damping layer and an inner reinforcing bar.

[0014] The connecting frame is embedded in the connecting layer of the wall at both ends, which not only enhances the connection strength between the wall and the damper, but also makes the entire damper system more stable. This design makes the damper maintain its position stable when subjected to external force, and is not easy to fall off or fail. The reinforcing bar and the concrete filling layer inside the connecting frame jointly constitute a solid support system. The reinforcing bar provides good tensile performance, and the concrete filling layer provides good compression performance and integrity. This synergistic effect makes the damper maintain its shape and stability when subjected to shear force, and is not easy to be damaged.

[0015] Preferably, the reinforcing bar is wrapped by the filling layer, and both ends of the reinforcing bar are welded with the connecting frame.

[0016] The design of the inner reinforcing bar increases the stiffness and strength of the viscous colloid damping layer, and improves the energy dissipation capacity. The end of the X-shaped inner reinforcing bar is connected with the connecting plate to form a stable support structure. When the damper is subjected to shear force, the X-shaped inner reinforcing bar can produce elastic deformation and absorb energy, thereby further enhancing the shear resistance of the damper.

[0017] Preferably, the connecting piece is welded with the connecting frame, and the connecting plate is bonded with the damping layer by an adhesive.

[0018] Preferably, the damping layer is composed of viscous colloid.

[0019] Preferably, the inner reinforcing bar is wrapped by the damping layer, the inner reinforcing bar is made of elastic metal material, and the shape of the inner reinforcing bar is X-shaped.

[0020] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0021] 1. This building's shear damper, through the coordinated arrangement of a connecting frame, reinforcing bars, infill layer, connectors, connecting plates, joint plates, damping layer, and internal reinforcement, features a connecting frame threaded onto the outer surface of the connectors. The two ends of the connecting frame are embedded in the connecting layer of the wall. Reinforcing bars are located inside the connecting frame, and a concrete infill layer lies within the connecting frame. The infill layer and connecting layer are integrated. This multi-layered structural combination of damping layer, joint plates, connectors, and connecting plates creates an effective mechanical transmission path and energy dissipation mechanism. This multi-layered composite structure can more effectively disperse and absorb external loads, reducing stress concentration within the structure.

[0022] As a key component, the connecting frame is embedded at both ends in the connecting layer of the wall, which not only enhances the connection strength between the wall and the damper but also makes the entire damper system more stable. This design allows the damper to maintain its positional stability under external forces, making it less prone to detachment or failure. The steel reinforcement and concrete infill layer inside the connecting frame together form a robust support system. The steel reinforcement provides good tensile strength, while the concrete infill layer provides good compressive strength and overall integrity. This synergistic effect allows the damper to maintain its shape and stability under shear forces, making it less prone to damage.

[0023] 2. The shear damper of this building features an X-shaped internal reinforcement design. This X-shaped reinforcement within the viscous colloidal damping layer not only increases the stiffness and strength of the damping layer but also enhances its energy dissipation capacity. The ends of the X-shaped reinforcement connect to the connecting plate, forming a stable support structure. When the damper is subjected to shear force, the X-shaped reinforcement can undergo elastic deformation and absorb energy, thereby further enhancing the damper's shear resistance.
