Single-climbing aluminum alloy folding outdoor escape ladder

Abstract

The invention belongs to the field of building outdoor self-rescue escape, and relates to a single-climbing aluminum alloy folding outdoor escape ladder. A foldable inlet slow step pedal is hinged between an inlet wall-attached frame and the bottom of an inlet protective frame in an entry unit, a ladder unit comprises an upper ladder unit and the lower ladder unit, the upper ladder unit comprisesan upper ladder wall-attached frame and an upper ladder protective frame, the upper ladder wall-attached frame is fixedly installed with an upper folding ladder on the left or right side, a foldable ladder slow step pedal is hinged at the bottoms of the upper ladder wall-attached frame and the upper ladder protective frame, the lower ladder unit is fixedly installed on the upper ladder wall-attached frame and the upper ladder protective frame of the gap formed between the inlet slow step pedal and the ladder slow step pedal, the lower ladder unit comprises a lower ladder wall-attached frame installed with a lower folding ladder, and a stair protective net. The single-climbing aluminum alloy folding outdoor escape ladder solves the problems of complicated escape route setting of the existing outdoor escape ladder, poor anti-theft, inconvenient assembly and disassembly, and inability to achieve structure linkage trigger opening.

Description

technical field [0001] The invention belongs to the field of building outdoor self-rescue and escape, and relates to a single-climbing aluminum alloy folding outdoor escape ladder, in particular to a kind of high-rise household and high-rise public office, such as natural disasters, fire accidents and other irresistible disasters. Single climbing aluminum alloy folding outdoor escape ladder. Background technique [0002] With the development of society and the shortage of land resources, there are fewer and fewer low-rise buildings, and people are used to living in high-rise buildings. However, once a dangerous situation occurs in a high-rise building, people can only passively wait for rescue or use life-saving ladders to escape. When a fire breaks out in a multi-storey or high-rise building, people can only evacuate through the fire exits in the building, followed by waiting for fire alarm rescue. It is difficult for trapped people to escape and the temperature of the esc...
