Description

Folding fire ladder that possesses return bend

Technical Field

The utility model relates to a fire-fighting equipment technical field specifically is a folding fire ladder that possesses return bend.

Background

Fire control is to eliminate hidden troubles and prevent disasters (i.e. to prevent and solve human, natural and accidental disasters in life, work and learning processes), and certainly the narrow meaning of people in the early stage of understanding is: meaning (extinguishing) fire. A Fire control; fire lighting; fire protection extinguishes and prevents fires. Also refers to fire extinguishing and preventing personnel. Guo Xiao Cheng (Zhejiang Guangfu Shu Ji): "defense team and patrol police have fierce fire, and both sleeves are decorated with white cloth to show integrity. "such as: the fire fighting must be held in position. For example: fire engine, fire control technique. China has a history of more than two thousand years of fire fighting, and the word "fire fighting" is introduced from Japan in the twentieth century and is a foreign language. But the root of "fire protection" is in china. Characters in japan evolved from chinese characters, which began to be introduced into japan as early as five years (284 years) of western jin taikang. The word "fire-fighting" is not only the same in character form as Chinese characters, but also has no difference in character meaning. Modern fire fighting is to be understood more deeply as eliminating hazards and preventing disasters the fire ladders are usually steel stairs, intended for fire fighters, the location and number of which are determined according to the nature, number of floors and fire protection requirements of the building. The fire ladder is divided into a straight upper type and an inclined type: the vertical type is mostly a steel bar ladder stand and is only limited to be used in the range of height difference of one layer and two layers; the inclination of the inclined type is 60-80 degrees, and a handrail, a breast board, an overhanging rest platform and the like need to be arranged. In order to meet the use requirement and safety of high-rise buildings, lifting ports with three fences of not less than 600 x 700 mm are reserved on the platform. The fire ladder has large-scale fire ladder, also has small-size fire ladder, and small-size fire ladder generally all can fold, but current fire ladder is fixed insecure when the slope is placed, has the potential safety hazard, consequently needs to improve.
