Description

Technical Field

[0001] This utility model relates to the field of building vibration reduction, specifically to a composite damper suitable for multi-directional seismic action. Background Technology

[0002] In the field of building engineering, dampers are important vibration reduction components that ensure the safety of various building structures. They can respond quickly when an earthquake occurs and effectively consume the huge energy released by the earthquake through the movement of their own specific structure or the action of the internal medium, thereby significantly reducing the impact of seismic loads on the main structure of the building and reducing damage such as cracking, deformation or even collapse.

[0003] Existing dampers are mostly single rod-shaped structures. When in use, they can only reduce vibrations in unidirectional earthquakes along the length of the damper. When encountering multidirectional combined earthquakes such as horizontal, vertical and oblique earthquakes, they have problems with poor vibration reduction adaptability and low energy consumption efficiency.

A viscous damping rod is rotatably connected between two adjacent connecting seats. A connecting rod frame is rotatably connected between the connecting seat and the top plate and the bottom plate. The rotatable connections between the connecting seat and the bottom plate, and between the connecting seat and the connecting rod frame, are all ball joints.

[0006] To further explain, the connecting seat has an arc-shaped structure.

[0007] Further explanation: The connecting rod frame includes a rotating frame body rotatably connected to the top plate or the bottom plate. The rotating frame body is U-shaped with an opening facing downwards. The bottom of the rotating frame body is provided with an outwardly extending protrusion.

[0012] The beneficial effects are: By using the triangularly distributed connecting seats between the top and bottom plates, and the viscous damping rods that rotate between adjacent connecting seats, multi-directional seismic energy can be efficiently dissipated, significantly improving the vibration reduction and noise reduction effect.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] First embodiment: See Figures 1-5 As shown, this utility model provides a composite damper suitable for multi-directional seismic action, including a top plate 1 and a bottom plate 2, with a damping component 3 provided between the top plate 1 and the bottom plate 2; The damping component 3 includes three connecting seats 301, which are arranged in a triangle between the top plate 1 and the bottom plate 2. Adjacent connecting seats 301 are connected by a viscous damping rod 302 through a ball joint, that is, there are also three viscous damping rods 302. The three viscous damping rods 302 and the three connecting seats 301 together form a closed triangular damping unit. When encountering an earthquake, the viscous damping rods 302 can consume earthquake energy through the shear deformation of the internal viscous medium. The rotational connection allows the viscous damping rods 302 to flexibly adjust their angle with the earthquake displacement, ensuring that they can effectively play an energy-dissipating role under earthquakes in multiple directions such as horizontal, vertical and oblique. The connecting seat 301 is rotatably connected to the top plate 1 and the bottom plate 2 by a connecting rod frame 4. The connecting rod frame 4 plays the role of transmitting seismic displacement and force, and evenly transmits the seismic force borne by the top plate 1 or the bottom plate 2 to the three connecting seats 301, and then the energy dissipation and vibration reduction are carried out through the viscous damping rod 302. Furthermore, the rotational connections between the connecting seat 301 and the base plate 2, and between the connecting seat 301 and the connecting rod frame 4, are all ball joints. The ball joint structure has multiple degrees of rotational freedom, which can adapt to the complex relative displacements between the components under seismic action, effectively reduce stress concentration, and further improve the multi-directional damping adaptability of the damper and the overall structural durability.

[0018] The connecting seat 301 has an arc-shaped structure. Since the connecting seat 301 is set to correspond with the three fixed points of the damping component 3, the connecting seat 301 needs to bear the damping force transmitted by the viscous damping rod 302 and the structural displacement force transmitted by the connecting rod frame 4 at the same time. Under multi-directional seismic action, the force direction changes continuously. The arc-shaped structure can disperse and transmit the force in each direction along the arc-shaped surface to avoid stress concentration in local areas.

[0019] Both the top plate 1 and the bottom plate 2 are circular or annular structures and are coaxially arranged. The top plate 1 and the bottom plate 2 are provided with multiple mounting holes to assist in the installation and fixing of the top plate 1 and the bottom plate 2.

[0020] The second embodiment differs from the first embodiment in that: The connecting rod frame 4 includes a rotating frame 401 rotatably connected to the top plate 1 or the bottom plate 2. The rotating frame 401 is U-shaped with its opening facing downwards, and its internal cavity forms a sliding cavity. The bottom of the rotating frame 401 is provided with an outwardly extending protrusion 401a. It also includes a plug rod frame 402 that is ball-jointed with the connecting seat 301. The plug rod frame 402 slides with the inner opening of the rotating frame 401 to achieve linear guidance between the rotating frame 401 and the plug rod frame 402. The high end of the plug rod frame 402 is provided with a stop bar extending from the opening of the rotating frame 401. 402a, the stop bar 402a is located above the protrusion 401a, and a thrust spring 403 is provided between the stop bar 402a and the protrusion 401a. The thrust spring 403 absorbs part of the seismic energy through elastic deformation to achieve auxiliary energy dissipation. After the seismic action weakens or disappears, the thrust spring 403 relies on its own elastic restoring force to push the plug frame 402 to slide in the opposite direction along the rotating frame 401, which drives the connecting seat 301 and the entire damping assembly 3 to return to the initial position, significantly improving the reusability and shock absorption stability of the damper.

[0021] The two ends of the thrust spring 403 are respectively engaged with the stop bar 402a and the protrusion 401a.

[0022] The third embodiment differs from the first embodiment in that: Both ends of the viscous damping rod 302 are rotatably connected to the connecting seat 301 via universal joints. The use of universal joints to achieve the rotatable connection between the two provides sufficient freedom for the multi-directional movement of the viscous damping rod 302. The universal joint has the structural characteristic of rotating around multiple axes in space. When encountering multi-directional seismic forces, the connecting seat 301 will undergo complex rotation and movement with the seismic displacement. The universal joints enable the two ends of the viscous damping rod 302 to flexibly adapt to the movement posture of the connecting seat 301. Whether it is horizontal shear displacement, vertical tension and compression, or oblique composite displacement, it can ensure that the viscous damping rod 302 always maintains a reasonable force angle.

[0023] The viscous damping rod 302 is a hydraulic or silicone oil type viscous damping rod. The hydraulic type viscous damping rod 302 uses hydraulic oil as the damping medium and utilizes the flow resistance of hydraulic oil in the flow channel to form damping force. It has the advantages of large damping force, wide adjustment range and fast response speed. It can quickly respond to the instantaneous large displacement and large energy input generated by strong earthquakes and efficiently consume earthquake energy. It is suitable for building projects with high seismic intensity, large structural load and strict requirements for energy consumption capacity, such as high-rise buildings, long-span bridges and other key structures.

[0024] The silicone oil viscous damping rod 302 uses silicone oil as the damping medium. Silicone oil has excellent temperature stability, chemical stability and anti-aging properties. Its damping performance is less affected by changes in ambient temperature. It can maintain a stable energy dissipation effect over a wide temperature range. Moreover, it operates smoothly and with low noise. It is suitable for areas with large temperature variations or structures with high requirements for vibration damping stability and long-term reliability, such as buildings in cold regions and buildings where precision equipment rooms are located. It effectively ensures that the damper can continuously play a stable multi-directional vibration damping role under different environmental conditions.

[0025] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
