Description

Technical Field

[0001] The utility model belongs to the technical field of building seismic isolation, and specifically refers to a metal damper combined with a rubber seismic isolation support. Background Art

[0002] Seismic isolation bearings refer to supporting devices that are installed in structures to meet seismic isolation requirements, while rubber seismic isolation bearings are devices that are made by overlapping the respective advantages of steel plates and rubber and are used in buildings. They can increase the seismic resistance of the building structure under the effects of horizontal and vertical earthquakes, torsion, etc.

[0003] Existing rubber seismic isolation bearings, such as an external metal damper combined with rubber seismic isolation bearing disclosed in application number CN202023178391.6, adopt an external U-shaped metal damper, which is easy to remove or add, and the rubber bearing can be reused, making the rubber bearing easy to design, produce and install, with low maintenance difficulty and low cost. The rubber bearing can be easy to design and maintain isotropy, while reducing the stress level and damage accumulation of the U-shaped metal damper, and improving the failure displacement and ductility of the rubber bearing.

[0004] However, in actual use, although the U-shaped metal damper is easy to observe damage, it has low structural strength and is easily deformed under stress. Its seismic isolation and energy dissipation capacity is poor. As the vibration continues, it will more or less generate circumferential torque. The metal damper combined with rubber seismic isolation bearing in the prior art has poor torsional resistance. Therefore, we propose a metal damper combined with rubber seismic isolation bearing to solve the above problems. Utility Model Content

[0005] In view of the above situation and to overcome the defects of the prior art, the utility model provides a metal damper combined with a rubber seismic isolation bearing, which effectively solves the problem that the metal damper used in the existing metal damper combined with a rubber seismic isolation bearing has poor seismic isolation and energy dissipation capacity and is easy to be damaged, and solves the problem that the existing seismic isolation bearing has poor torsional resistance.

[0006] The technical solution adopted by the utility model is as follows: The utility model proposes a metal damper combined with a rubber seismic isolation bearing, comprising a rubber seismic isolation bearing, an upper connecting steel plate, a lower connecting steel plate and an embedded steel plate, the upper connecting steel plate and the lower connecting steel plate are respectively connected to the upper and lower ends of the rubber seismic isolation bearing by connecting bolts, the embedded steel plate is arranged on the upper and lower sides of the upper connecting steel plate and the lower connecting steel plate, the upper connecting steel plate and the lower connecting steel plate are both provided with connecting parts, and the connecting parts are evenly distributed around the rubber seismic isolation bearing along the circumferential direction, a viscous damper is rotatably connected between the connecting parts on the upper connecting steel plate and the lower connecting steel plate, a metal damper is arranged between the upper connecting steel plate and the lower connecting steel plate, and the metal damper is coaxially arranged with the rubber seismic isolation bearing.

[0007] As an improvement of the present solution, the embedded steel plate is plugged and connected with a connecting anchor bolt, and the connecting anchor bolt passes through the upper connecting steel plate and the lower connecting steel plate. The connecting anchor bolt is threaded with a connecting nut, and the connecting anchor bolt and the connecting nut respectively connect and fix the embedded steel plate to the upper connecting steel plate and the lower connecting steel plate.

[0008] As an improvement of the present solution, the rubber seismic isolation bearing includes a steel plate layer, a rubber layer and a rubber protective layer. The steel plate layer is respectively connected to the upper connecting steel plate and the lower connecting steel plate by connecting bolts. The rubber layer and the steel plate layer are stacked, and the rubber protective layer is wrapped around the outside of the steel plate layer and the rubber layer.

[0009] As an improvement of the present solution, the metal damper includes a fixing ring, a metal plate and screws. The fixing ring is plugged in and connected to the rubber seismic isolation support and is fixedly connected to the upper connecting steel plate and the lower connecting steel plate by screws respectively. The metal plates are evenly distributed on the fixing ring along the circumferential direction.

[0010] As an improvement of the present solution, a pre-embedded steel bar is fixed to one side of the pre-embedded steel plate away from the rubber seismic isolation bearing, and a connecting head is fixed to the other end of the pre-embedded steel bar.

[0011] As an improvement of this solution, the steel plate layer and the rubber layer are arranged at intervals and coaxially, the fixing ring and the rubber seismic isolation support are coaxially arranged, the fixing ring and the metal plate are arranged vertically, and the metal plate is arranged centripetally along the diameter direction of the fixing ring.

[0012] As an improvement of the present solution, the fixing ring is arranged in an O-shape, and the metal plate is arranged in the form of a thin plate with wider ends.

[0013] The beneficial effects achieved by the utility model using the above structure are as follows:

[0014] 1. The viscous damper is evenly distributed along the circumferential direction. Through the combined structural design, the torque in the circumferential direction can be weakened, thereby improving the torsional resistance of the support.

[0015] 2. By arranging a metal damper outside the support body composed of a rubber layer and a steel plate layer, the plastic deformation of the metal plate is used to absorb the vibration energy, thereby improving the shock absorption and energy dissipation capacity of the seismic isolation support, and the overall structure is simple to install.
