A fuse assembly, a fuse type building isolation rubber bearing and a building

Abstract

The invention discloses a fusing assembly, a fusing type building shock-isolation rubber bearing and a building, comprising a first assembly, a second assembly, a third assembly and a fusing rod; the second assembly and the third assembly are provided with a fusing cavity in the center; the fusing One end of the rod is fixedly inserted in the middle of the first component, and the other end of the fuse rod protrudes from the second component and the third component and is threaded with a safety rope; the other end of the fuse rod and the safety rope are both placed in the fuse cavity. The invention prevents or slows down the shearing movement of the vibration-isolation rubber bearing when it is subjected to a horizontal force not exceeding the yield displacement and a horizontal force not exceeding the fortification seismic intensity. The vibration-isolation rubber bearing does not move frequently under the action of high-frequency and low-intensity earthquakes, so as to protect the vibration-isolation rubber bearing. To ensure that when an earthquake with fortification intensity occurs, the vibration-isolation rubber bearing can perform as expected.

Description

technical field [0001] The invention relates to the technical field of building shock-isolation bearings, in particular to a fuse assembly, a fuse-type building shock-isolation rubber bearing and a building. Background technique [0002] The traditional anti-seismic technology is to firmly connect the superstructure and the foundation of the building. In order to build a stronger house, thicker steel bars and more concrete are poured, but the anti-seismic effect is not ideal. The seismic isolation bearing is to add a seismic isolation layer between the upper structure and the foundation, and install a rubber seismic isolation bearing to play a role of soft connection with the ground. Through this technology, about 80% of the energy of the earthquake can be offset. The rubber seismic isolation bearing is a kind of fusing type building isolation rubber bearing in the seismic isolation bearing. It is made of alternately laminated multi-layer steel plates and rubber. The steel p...

Problems solved by technology

Therefore, in daily use and earthquake-prone areas, after bearings are subjected to high-frequency, low-intensity horizontal shearing, their horizontal resistance capacity gradually attenuates, which may easily lead to insufficient ability of bearings to resist horizontal deformation under rare earthquakes. situation occurs

[0005] At the same time, if the superstructure is subjected to long-term eccentric loads, the support will be unable to recover from the long-term shear deformation in a single direction. In this state, it will also have an adverse effect on the support
