A barrier-free escape system for high-rise buildings

Abstract

The invention discloses a barrier-free escape system for a high-rise building, which relates to the technical field of building safety protection and entertainment facilities. The vertical evacuation area is composed of anti-vertigo stairs, elastic work slides, elastic deceleration doors, rotating pull rings and standing exits. The vertical evacuation area is equipped with 2 elastic work slides and 1 anti-vertigo staircase. This system can take into account both emergency escape and daily traffic. The invention relies on the elastic force of the elastic deceleration door to do work, safely consumes the mechanical energy of escapees, can avoid the risk of scratches caused by ordinary slides, and at the same time helps vulnerable people to escape without obstacles.

Description

technical field [0001] The invention relates to the technical field of building safety protection and entertainment facilities, in particular to a barrier-free escape system for high-rise buildings. Background technique [0002] Escape from high-rise buildings is a difficult problem in the world, and there are two major challenges: horizontal evacuation and vertical traffic. Once high-rise residents encounter a fire and close their doors and are trapped in a sea of ​​​​flames, they can only hope to escape outdoors. However, the higher the floor, the more difficult it is to escape outdoors, and the greater the risk of falling from the building. Currently, there are two types of indoor vertical evacuation systems: elevators and stairs. In the event of a fire, the elevator may malfunction and trap people, vulnerable people may be pushed down when going down the stairs, causing chain stampede accidents, and it is difficult for the injured to use the stairs to escape on their ow...

AI Technical Summary

Problems solved by technology

Its disadvantages are as follows: it is necessary to manually press the key and wait for the electric drive mechanical device to put down the slideway and it can be used after it is fully connected, and the power failure will fail; each floor of the stairs and the slideway has two sharp turns of 180 degrees, which is easy to cause Survivors are stunned; the descent speed is slow, and the escape efficiency has no advantage over stairs

However, there are still three problems that have not been solved: the horizontal evacuation path is single, once the residents of high-rise buildings encounter a fire and the door is closed, it is difficult to survive; each floor covers an area of ​​16m 2 The unique four-channel design, although the escape efficiency is high, it cannot take into account the needs of daily traffic and going up and down the stairs, resulting in the escape system cannot completely replace the existing stairs, which brings additional land occupation and cost; the exit of the slideway requires people to actively use the pull ring In order to realize diversion, escapers are easy to be uprooted by follow-up escapers within the time of standing up, resulting in blockage and confusion at the escape scene
