Description
Technical Field
The utility model relates to a shock insulation technical field especially relates to a fire protection device and have its multi-functional rubber supporting component.
Background
Earthquakes are natural disasters which are difficult to predict, have strong burstiness and great harmfulness to human society. Under the action of earthquake, the destruction of the building is the most direct cause of economic loss and casualties, so the most effective measure for relieving earthquake disasters is to improve the earthquake resistance of the building.
The seismic isolation support is a supporting device arranged between an upper pier and a lower pier of a building for achieving the seismic isolation requirement, and can make large-amplitude displacement in the horizontal direction when an earthquake occurs, and about 80% of energy of the earthquake can be offset by the technology, so that the seismic energy received by the upper pier is greatly reduced.
The shock insulation rubber support is a product emerging in recent years, and compared with the traditional rigid shock insulation technology, the shock insulation rubber support is excellent in shock absorption effect, safe and reliable, and the main principle is that the shock insulation rubber support can prolong the vibration period of buildings, bridges and the like, so that the seismic response is further reduced. However, as the rubber material is combustible, the fire resistance is poor, when a fire disaster occurs, the rubber material in the shock insulation rubber support can be slowly combusted, so that the shock insulation support is ineffective, and the building can be collapsed in a serious case. In the prior art, the protection to shock insulation rubber support has two kinds: firstly, the seismic isolation chambers are independently arranged underground or on the ground, but the mode not only occupies the space of a building, but also increases the building cost; and secondly, a fireproof protective layer which is not in contact with the shock insulation rubber support is arranged on the periphery of the shock insulation rubber support and is fixed between the upper structure and the lower structure, but in the mode, when an earthquake occurs, the shock insulation rubber support can move along with the shock insulation rubber support to a large extent, and the phenomena of cracks, deformation and falling cannot be avoided, when a fire disaster occurs again after the earthquake, the areas with the cracks, deformation and falling on the fireproof layer can be directly baked by high temperature or naked fire, and the fireproof performance is not provided any more, so that the shock insulation rubber support is burnt.
Therefore, in order to ensure that the seismic isolation rubber support can be normally used when a fire disaster occurs or after the fire disaster is over, or when a fire disaster occurs again after an earthquake, and further ensure the safety of a building, the fire prevention structure of the seismic isolation support of the seismic isolation building needs to be considered heavily.
