Problems solved by technology
[0003] The current seismic isolation bearings usually have the following problems: First, the automatic reset ability is poor, and the seismic isolation structure with a large aspect ratio is easy to be pulled into yield and cause the entire structure to overturn and fail
Second, the friction force is constant, which cannot meet the isolation requirements under various seismic conditions.

Embodiment
[0050] see Figure 1-Figure 2 , In the first aspect, the embodiment of the present application provides a self-resetting vibration-isolation support 101 , including a first support 110 , a second support 120 and a sliding block 130 . The top surface of the first support 110 is recessed with a first sliding groove 111, the bottom surface of the second support 120 is recessed with a second sliding groove 121, and the sliding block 130 is used to be slidably accommodated in the first sliding groove 111 and the bottom surface of the second support 120. between the second slide grooves 121 .
[0051] see image 3 , in the embodiment of the present application, the first sliding groove 111 is an arc-shaped groove whose concave depth gradually decreases from its center to its circumferential edge, that is to say, the first sliding groove 111 is similar to a ball The arc groove structure of the cover. After the sliding block 130 slides between the first sliding groove 111 and the s...

The invention relates to a self-resetting seismic isolation support and a seismic isolation device, and belongs to the technical field of building seismic reduction and isolation structures. The self-resetting seismic isolation support comprises a sliding block, a first support and a second support. A first sliding groove is formed in the top face of the first support in a sunken mode and is an arc-shaped groove with the depth being gradually decreased from the center to the peripheral edge. The sliding block is slidably arranged between the first sliding groove and a second sliding groove andcomprises two first side faces oppositely arranged in the first preset direction, and two second side faces oppositely arranged in the second preset direction. One or more of the first sliding grooveand the second sliding groove are provided with friction base faces, and the sliding block is provided with a friction face attached to the friction base faces. When the sliding block slides from thecenter of the first sliding groove to the edge of the first sliding groove in the first preset direction and the second preset direction, the contact area between each friction base face and the friction face is gradually increased. Self-resetting can be realized, and friction force can be changed with displacement. The seismic isolation device comprises the seismic isolation support, a first connecting plate which can be detached from the bottom of the first support, and a second connecting plate which can be detached from the top of the second support.
Description
technical field [0001] The present application relates to the technical field of building shock-absorbing and isolating structures, in particular to a self-resetting shock-isolation support and a shock-isolation device. Background technique [0002] Traditional engineering anti-seismic technology is based on the estimated parameters of site fortification ground motion, and adopts the method of improving the strength and ductility of the structure itself to resist earthquake action. However, due to the strong randomness of ground motion, this technology may not meet the safety requirements of super-fortification earthquakes. Require. Seismic isolation technology refers to the reasonable addition of seismic isolation devices in engineering structures, thereby prolonging the basic period of the structure, reducing the earthquake effect, and setting damping devices to consume seismic input energy, and finally achieve the effect of protecting the safety of the main structure. ...
