Slide plate type emergency staircase

Abstract

The invention relates to the technical field of architectural fire control, in particular to a slide plate type emergency staircase. The slide plate type emergency staircase is composed of a horizontal backing plate, a slope layer, oblique slide plates, a stair section, rotating shafts, motors, a shaft sleeve, a baffle and a staircase horizontal section, wherein the sides of the staircase horizontal section and the stair section adjacent to the staircase wall are respectively provided with one rotating shaft, and the motor shaft of each motor is fixedly connected with the rotating shaft; power switches of the motors are arranged in a fire control room of the whole building; the rectangular oblique slide plates which are parallel to the bottom surface of the stair section are laid on upper surface of the stair section; and the horizontal backing plate is laid on the upper surface of the staircase horizontal section. The slide plate type emergency staircase can be used for evacuating people in a slide mode in an emergency, thereby increasing the evacuation speed, providing convenience for the old, weak, sick, disabled and other people having weak legs, and greatly raising the success rate of safety evacuation.

Description

Technical field [0001] The invention relates to the technical field of building fire protection, in particular to a skateboard emergency staircase. Background technique [0002] The stairs used in the existing fire-proof stairwells and smoke-proof stairwells of high-rise residential buildings are all broken-line stairs. When a fire occurs, people can evacuate through the stairs and can only step down the stairs with their feet alternately at a high frequency. This way of going downstairs seems too slow when a critical situation occurs, and it is far from meeting the needs of users for short-term safe escape. Especially for the elderly, weak, sick, disabled and other people with insufficient leg and foot flexibility, the time to get out will be longer, which greatly reduces the success rate of safe evacuation. Summary of the invention [0003] In order to solve the shortcomings of the prior art, the present invention provides a skateboard emergency staircase that can temporarily h...

[0002] The stairs used in the fire-proof stairwells and smoke-proof stairwells of existing high-rise residential buildings are all broken-line stairs. When a fire breaks out, people evacuate through the stairs. Downstairs, this way of going downstairs seems to be too slow when a critical situation occurs, and it is far from meeting the needs of users to escape safely in a short time

Especially for the old, weak, sick, disabled and other people whose legs and feet are not flexible enough, the time to escape will be longer, which greatly reduces the success rate of safe evacuation
