Deformable stair capable of being deformed into sliding type stair

Abstract

The invention discloses a deformable stair capable of being deformed into a sliding type stair. The technical problems that in the prior art, when dangerous cases such as a fire disaster happen in a stair, the escape efficiency of residents is low, and the escape opportunity is prone to being delayed are solved. The deformable stair comprises a hidden plate assembly, a driving assembly and a transmission assembly, wherein the hidden plate assembly corresponds to stair steps, is in a contraction state at ordinary times so as not to affect the normal use function of the stair, and can be unfolded in emergency situations so as to deform the stair into the sliding type stair; the driving assembly is used for driving the hidden plate assembly to operate; the transmission assembly is connected with the hidden plate assembly and the driving assembly; and the driving assembly drives the hidden plate assembly to operate through the transmission assembly. The deformable stair is scientific and reasonable in design and convenient to use, and can be deformed into the sliding type stair when the dangerous cases such as the fire disaster happen, so that the escape efficiency of the residents isimproved, and the life and property safety of people is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, further belongs to the technical field of slides, and in particular relates to a deformed staircase which can be transformed into a sliding ladder. Background technique [0002] Stairs are components used as vertical communication between floors in buildings. It is used for traffic connection between floors and when the height difference is large. Stairs should also be provided in multi-storey and high-rise buildings with elevators and escalators as the main vertical means of transportation. Although elevators are used as the main vertical means of transportation in high-rise buildings, stairs are still reserved for escape in case of fire. Stairs are composed of continuous steps (also known as ladder runs), platforms (rest platforms) and enclosure components. The horizontal projection distance between the lowest and highest steps of the stairs is the ladder length, and the total heig...
