Fireproof seismic-isolating rubber support

Abstract

The invention discloses a fireproof seismic-isolating rubber support which comprises a seismic-isolating rubber support and heat-insulating fireproof components. Protecting rubber of the seismic-isolating rubber support is rubber high in flame retardance and heat insulativity, the heat-insulating fireproof components coat two ends of the seismic-isolating rubber support, each heat-insulating fireproof component comprises a thick fireproof coating, high-temperature-resistant cloth and high-temperature-resistant heat-insulating layers sequentially from inside to outside, and the high-temperature-resistant heat-insulating layers are stacked, combined and fixed on the periphery of the corresponding high-temperature-resistant fireproof cloth layer by layer and are of a louver structure. The fireproof seismic-isolating rubber support has good flame-retardant and heat-insulating effect. Even if an earthquake occurs, the seismic-isolating rubber support can generate horizontal shearing deformation to protect an upper structure of a building and has good fireproof and heat-insulating effect at ordinary times; when a fire disaster occurs, the seismic-isolating rubber support can well prevent a high-temperature heat source from influencing the fireproof seismic-isolating rubber support, and the fireproof seismic-isolating rubber support meets first-grade fireproof requirements.

Description

technical field [0001] The invention relates to the field of fire prevention and heat insulation protection of a shock-proof rubber bearing, in particular to a fire-proof and shock-isolation rubber bearing. Background technique [0002] At present, the seismic isolation rubber bearing has been widely used in the isolation engineering of buildings, bridges and equipment, which can significantly reduce the destructive effect of the earthquake on the structure and ensure the safety of the structure, people and property. However, the fire resistance of seismic isolation rubber bearings is generally poor, which threatens the fire safety of seismic isolation structures. Especially for earthquake-isolated building spaces with a large number of people, the fire protection level is relatively high, and it is generally required to meet the first-class fire protection requirements. Many existing fireproof structures are relatively complicated and costly, making it difficult to popular...

However, the fire resistance of the isolation rubber bearing is generally poor, which threatens the fire safety of the isolation structure.

Especially for earthquake-isolated building spaces with a large number of people, the fire protection level is relatively high, and it is generally required to meet the first-class fire protection requirements, but it is difficult to meet the first-class fire protection requirements only by relying on shock-isolation rubber bearings for fire prevention

Many existing fireproof structures are relatively complex and costly, making it difficult to popularize and apply
