Description

Escape fireproof safety cabinet

Technical Field

The invention relates to the field of safety cabinets, in particular to an escape fireproof safety cabinet.

Background

With the gradual enhancement of the national economic level and the continuous promotion of urbanization, the building heights of various civil residences or public buildings are continuously increased, and a large number of high-rise buildings and super high-rise buildings are pulled out to adapt to increasingly short building sites, but simultaneously bring about the fire safety problem.

According to the regulations of a building department, refuge floors or refuges need to be arranged on high floors or super high floors of a civil building, for the super high floors, the height of the refuge floor of the first super high floor is not more than 50 meters from the designed outdoor ground, meanwhile, the distance between adjacent refuge floors is not more than 50 meters, and in practice, once a fire disaster happens, the floors positioned in the middle of the refuge floors are not as close as the refuge floors, so that the life of escape personnel cannot be guaranteed; moreover, when a fire disaster occurs, the fire disaster is often in disorder, the smoke covers the escape indication mark in a diffused manner, the difficulty of searching for a refuge layer or a refuge room by the evacuees is further increased, after the time is prolonged, the oxygen is gradually diluted, the smoke inhaled by the evacuees is suffocated, and in fact 80% of the distress in the fire disaster is suffocated and died; as for the fire in the house, the deflagration phenomenon easily occurs because of more combustible substances, and at the moment, it is often unrealistic to seize the door to find the refuge layer.

For industrial buildings, whether plants or warehouses, the dangers are larger due to the fact that the stored or used flammable and even explosive substances are more, once a fire disaster occurs, the control is difficult, escape personnel have no refuge layer to temporarily avoid, and can only evacuate through evacuation walkways and evacuation stairs, and the time is often insufficient.

Therefore, there is a need for a device that can be used in civil or industrial buildings, can be flexibly placed, has high fire resistance, can isolate smoke and dust, and even has certain explosion-proof capacity, so that evacuees can hide in an emergency to ensure life safety.
