Embodiment 1

[0023] Embodiment 1. A kind of building anti-seismic protection device, as Figure 1-3 As shown, it includes a support block 2 arranged under the building 1, and a buffer device for releasing shock wave energy in the vertical direction is provided under the support block 2. The buffer device includes a position corresponding to the support block 2. Buffer seat 3, a buffer tank 31 is provided in the buffer seat, buffer liquid 32 is provided in the buffer tank 31, the support block is inserted into the buffer tank 31 and closely matched with the buffer tank 31, and the support block 2 is immersed in the buffer tank 31 In the buffer liquid; the bottom of the buffer seat 3 is provided with a wave reduction device for releasing shock wave energy in the horizontal direction, and the wave reduction device includes an upper base 4 and a lower bottom surface separated up and down for connection with the building foundation The lower base 42, the upper surface of the upper base 4 is fix...

Embodiment 2

[0024] Example 2, the buffer solution 32 described in Example 1 can be oil or water.

Embodiment 3

[0025] Example 3, such as figure 1 and figure 2 As shown, the left side or the right side of the buffer tank 31 described in Embodiment 1 is connected with an elastic return device for returning the buffer solution to the initial liquid level, and the elastic return device includes a buffer channel connected to the buffer tank 7. The buffer channel is provided with a return piston 8 and a return push rod 81 connected to the return piston at one end. The other end of the return push rod 81 protrudes from the outside of the buffer channel 7 and is connected to a push rod for pushing the return push rod in the buffer. An elastic piece that moves in the track, one end of the elastic piece is connected with the return push rod, and the other end of the elastic piece is against the limit piece 85 arranged on the outside of the buffer track. The material of the return push rod 81 can be high-temperature alloy steel, and the material of the elastic member can be alloy spring steel. ...

Abstract

A shake-proof protection device for a building comprises a supporting block under the building. A buffer device which is used for releasing the seismic energy vertically is arranged below the supporting block and comprises a buffer seat whose position corresponds to the supporting block. A buffer groove is formed in the buffer seat and provided with buffer liquid. The supporting block inserts into the buffer groove to be closely matched with the buffer groove and dips into the buffer liquid. A wave reduction device which is used for releasing the seismic energy horizontally is arranged below the buffer seat and comprises an upper base and a lower base, wherein the upper base and the lower base are separated from top to the bottom, the bottom surface of the lower base is used for being connected with the foundation of the building, the upper surface of the upper base is fixedly connected with the bottom surface of the buffer seat, the lower surface of the upper base and the upper surface of the lower base are respectively provided with an upper hemisphere surface and a lower hemisphere surface, and a wave reduction sphere which can roll is arranged between the upper hemisphere surface and the lower hemisphere surface. The shake-proof protection device for the building can release effect on the seismic wave of the building and fully protect the building and the objects in the building.

Description

technical field [0001] The invention relates to a structural system for earthquake protection of buildings, in particular to an earthquake protection device suitable for existing buildings. Background technique [0002] Earthquake is one of the natural disasters that threaten human life and property safety. The longitudinal wave makes the building bump up and down, and the building has no time to follow the movement, so that the dynamic load of the bottom pillars and walls suddenly increases, and the self-weight pressure of the upper part of the building is superimposed. If the bearing capacity of the bottom pillars and walls is exceeded, the bottom floor will collapse. The layer is like a hammer falling down, making the whole building "sit" down; the shear wave makes the building swing horizontally, if the strength or deformation capacity of the bottom column and wall is not enough, the whole building will be tilted or toppled in the same direction; if the seismic wave is ...
