A shock-isolation bearing for buildings with fire-proof and flame-retardant properties

Abstract

The invention discloses a building shock-isolation bearing with fireproof and flame-retardant properties, relates to the technical field of shock-isolation bearings, and comprises a first connecting plate, a second connecting plate is arranged above the first connecting plate, and the Two elastic fire-proof and flame-retardant plates are arranged between the first connecting plate and the second connecting plate. , so that when the second connecting plate is subjected to a lateral force, the slider pushes the connecting column to move, so that the push plate pushes the first electromagnet to move. At this time, the buffer plate presses the first buffer spring, and at the same time, the first electromagnet and the second electromagnet The repulsive magnetic field between them hinders the movement of the push plate, and at the same time, the push plate pushes the gas inside the buffer box to be discharged to the outside through the gas head. In this process, the push plate does work on the gas, thereby exerting a lateral force on the second connecting plate Buffering is performed, thereby improving the shock-isolation performance of the shock-isolation bearing.

Description

technical field [0001] The invention relates to the technical field of seismic isolation bearings, in particular to a seismic isolation bearing for buildings with fireproof and flame retardant properties. Background technique [0002] Earthquake is a natural disaster, and its huge effect is often the main factor leading to the damage or even collapse of engineering structures in earthquake areas. Seismic isolation means isolating earthquakes. Seismic isolation devices are installed at the base of buildings and structures or at a certain location to isolate or dissipate seismic energy, so as to avoid or reduce the transmission of seismic energy to the upper structure and reduce the structural vibration response. Slight movement and deformation, so as to ensure the safety of buildings during earthquakes. However, the buffering and energy dissipation effect of the existing shock-isolation bearing is not good, so that the shock-isolation effect is relatively poor. Contents of...
