Shock insulation support suitable for super-intensity earthquake action

Abstract

The invention relates to a shock insulation support suitable for super-intensity earthquake action. The shock insulation support comprises a support body and a lower connecting steel plate, the bottom of the support body is provided with a lower seal steel plate, and a cylindrical friction head is arranged in the middle position of the lower surface of the lower seal steel plate in a downward protruding mode; two vertically crossed sliding tracks are arranged on the upper surface of the lower connecting steel plate in a concave mode, and the inner walls of the sliding tracks at the junction are each shaped like a 90-degree circular chamfer, the portion, outside the sliding tracks, of the upper surface of the lower connecting steel plate is set to the combined embossed surface to serve as a first friction area, and the inner walls of the two sides of the sliding tracks are provided with soft friction pieces in a padding mode to serve as second friction channels. When super-intensity earthquake action occurs, the shock insulation support can achieve secondary energy consumption through the first friction area and the second friction channels, and effective protection can be provided for the support body and a building.

Description

technical field [0001] The invention relates to the technical field of seismic isolation of building structures, in particular to a seismic isolation support that can still exert its seismic isolation function under the action of super-intensity earthquakes. Background technique [0002] Seismic isolation is one of the most widely used shock-absorbing methods at present, and has the advantages of simple structure, obvious effect, and stable performance. But at present, all earthquake-isolated buildings without exception deliver the safety of the entire building to the earthquake-isolation layer. When the earthquake-isolation support in the earthquake-isolation layer plays its role stably, it can ensure that the buildings on the upper part of the earthquake-isolation layer However, due to the randomness of the earthquake action, when the isolation layer encounters a super-intensity earthquake, the isolation support in the isolation layer is very likely to exceed its own limit...

But at present, all earthquake-isolated buildings without exception deliver the safety of the entire building to the earthquake-isolation layer. When the earthquake-isolation support in the earthquake-isolation layer plays its role stably, it can ensure that the buildings on the upper part of the earthquake-isolation layer However, due to the randomness of the earthquake action, when the isolation layer encounters a super-intensity earthquake, the isolation support in the isolation layer is very likely to exceed its own limit deformation range and cause the entire isolation layer to be damaged. failure of the seismic layer, thereby putting the entire building at risk of destruction
