High-rise building fire escape ladder

Abstract

The invention discloses high-rise building fire fighting escape staircases comprising the upper fire fighting escape staircases and the lower fire fighting escape staircases which are arranged at upper fire fighting escape exits and lower fire fighting escape exits which are formed in an outer wall of upper and lower floors. The lower ends of the upper fire fighting escape staircases are hinged to the upper ends of the lower fire fighting escape staircases mutually. The lower ends of the lower fire fighting escape staircases are mounted at the bottom of the lower fire fighting escape exits in a hinged mode. The upper ends of the upper fire fighting escape staircases are mounted at the upper fire fighting escape exits in an up-down sliding mode. At the upper sliding ends of the upper fire fighting escape staircases, the upper and lower fire fighting escape staircases close the upper and lower fire fighting escape exits together; and at the lower sliding ends of the upper fire fighting escape staircases, the upper and lower fire fighting escape staircases which form triangular supporting outward open the upper and lower fire fighting escape exits correspondingly to form channels of the upper floors and lower floors. Two rows of the upper and lower fire fighting escape exits are vertically formed in the outer wall. The upper and lower fire fighting escape staircases are arranged in a staggered mode relative to the upper and lower fire fighting escape exits of different floors. The high-rise building fire fighting escape staircases and a wall body are integratedly designed, the appearance is attractive, practicability is achieved, operation is easy, and the high-rise building fire fighting escape staircases are safe and reliable fire fighting escape facilities.

Description

technical field [0001] The invention relates to a fire escape facility, in particular to a fire escape ladder for a high-rise building.
