Problems solved by technology

At present, the above-mentioned seismic isolation devices all isolate horizontal earthquakes, but do not have any effect on the isolation of vertical seismic waves. Since vertical seismic waves and horizontal seismic waves have the same magnitude of damage to structures, it is urgent to invent vertical isolation devices for engineering structures. Seismic devices to effectively improve the ability of engineering structures to resist vertical earthquakes

Embodiment approach

[0021] First make the vertical damper 3. The vertical damper is composed of three steel plates and one or two damping materials. The viscoelastic damping material is pasted on the middle and lower sides of the vertical middle steel plate, and the viscoelastic damping material is pasted on the outside The steel plates 32 on both sides vertically cross the damping material between the three steel plates and expand the steel plates with lead pins 34 at last, and they are connected into a whole to form a vertical damper. The damping material can also be composed of multiple alternately arranged steel plates and damping material layers to form a multi-layer structure.

[0022] The vertical middle steel plate 431 of the vertical damper 3 is connected with the upper horizontal steel plate 1, and the vertical side steel plates of the vertical damper 3 are connected with the lower horizontal steel plate 2. In addition, on the plane of the upper horizontal steel plate 1, there is Bolt h...

Abstract

The vertical seismic isolation device for engineering structures is a device used for anti-seismic, seismic isolation and shock absorption in civil engineering. The device is composed of a vertical damper, an upper horizontal steel plate and a lower horizontal steel plate. The upper part of the vertical damper and the The upper horizontal steel plate is connected, the lower part of the vertical damper is connected with the lower horizontal steel plate, and the upper horizontal steel plate and the lower horizontal steel plate are respectively provided with bolt holes.

Description

1. Technical field: [0001] The invention is an anti-shock, shock-isolation and shock-absorbing device for civil engineering. 2. Background technology: [0002] When an earthquake occurs, the ground motion will cause the vibration of the engineering structure. In order to isolate or inhibit the transmission of ground motion to the upper structure, seismic isolation devices can be installed between the top surface of the foundation and the bottom of the upper structure or other suitable positions of the engineering structure to reduce the dynamic reaction of the engineering structure. Theoretical research, experiments and engineering practice all show that the seismic isolation device is an effective means of earthquake reduction and disaster prevention for civil engineering structures. In the past two decades, various seismic isolation devices have been developed at home and abroad and used in engineering practice. These isolators include rubber isolators (unbonded lead lam...
