Fireproof protection device and multifunctional rubber support assembly provided with fireproof protection device

Abstract

The invention discloses a fireproof protection device and a multifunctional rubber support assembly provided with the fireproof protection device. The fireproof protection device comprises a fireproofwrapping layer enclosed by a plurality of groups of fireproof components, wherein each group of fireproof components comprises a plurality of sheet steel plates and a plurality of hinges used for connecting two adjacent steel plates in a hinged mode; the two steel plates located at the head and the tail end of each group of fireproof components are respectively connected with an upper supportingpier and a lower supporting pier through connecting seats; and the surfaces of each steel plate and each hinge are coated with fire-resistant coatings with thermal expansion properties. According to the fireproof protection device, on the premise of not influencing the shock isolation function of the shock insulation rubber support, the flame can be prevented from being directly contacted with theshock insulation rubber support when a fire occurs, so that the effect of fire protection of the shock insulation rubber support is achieved, the collapse of the building caused by fire failure of the shock insulation rubber support is effectively avoided, the building space is basically not occupied, the building cost is basically not increased, and the fireproof protection device has the advantages of being simple in structure, safe, reliable, convenient to construct and convenient to maintain.

Description

technical field [0001] The invention relates to the technical field of shock isolation, in particular to a fire protection device and a multifunctional rubber support assembly having the same. Background technique [0002] Earthquake is an unpredictable natural disaster with strong suddenness and great harm to human society. Under the action of earthquake, the destruction of buildings is the most direct cause of economic losses and casualties, so the most effective measure to reduce earthquake disasters is to improve the earthquake resistance of buildings. [0003] The seismic isolation support is a supporting device installed between the upper pier and the lower pier of the building in order to meet the requirements of seismic isolation. When an earthquake occurs, the seismic isolation support can make a relatively large displacement in the horizontal direction. Through such technology, about 80% of the energy of the earthquake can be offset, so that the earthquake energy ...

AI Technical Summary

Problems solved by technology

However, since the rubber material itself is combustible and has poor fire resistance, when a fire occurs, the rubber material in the isolation rubber bearing will burn slowly, resulting in failure of the isolation bearing, and in severe cases, the collapse of the building

In the prior art, there are two types of protection for the shock-isolation rubber bearing: one is to set up a separate shock-isolation room underground or on the ground, but this method not only takes up the space of the building, but also increases the construction cost; It is by setting a layer of fireproof protective layer on the periphery of the vibration-isolation rubber bearing that does not contact the vibration-isolation rubber bearing, and is fixed between the upper structure and the lower structure. However, when an earthquake occurs in this way, it will The substantial movement of the shock rubber bearing will inevitably lead to cracks, deformation, and falling off. When a fire breaks out after the earthquake, the cracks, deformation, and falling off areas on the fireproof layer will be directly baked by high temperature or open flame. No longer fire resistant, resulting in the fire of the isolating rubber mounts
