Flat-step stair

Abstract

The invention relates to the building industry, particularly to a flat-step stair which achieves the purpose that when going upstairs, people are just like walking on the flat ground. The flat-step stair comprises 7 to 30 lifting steps, wherein each lifting step comprises pillars, a lifting plate, bearings, a foldable plate, a bottom plate and a jacking device, wherein the pillars are fixedly mounted on the building; the bottom plate is fixedly connected on the four pillars; the connection part is 2 to 5 cm to the bottommost ends of the pillars; the surface, facing downwards, of the bottom plate closely fits the building; and when people step on each lifting step, a weight switch is triggered, and the jacking device is energized to jack up the lifting plate. According to the flat-step stair, people can go to tall buildings just like walking on the flat ground, the deficiency of a traditional stair that the legs, feet and knees cannot endure more after people climb a few floors is compensated, a plurality of defects of an elevator are overcome, and an another technical route for goring upstairs and downstairs is developed.

Description

technical field [0001] The invention relates to the construction industry, in particular to flat stairs. Background technique [0002] When people are going up or down, they usually use ladders. Later, when there are buildings, fixed stairs are set in the buildings, and the stairs have become an indispensable part of building construction. For low-rise buildings, stairs are very important. It is suitable for going up and down stairs, and there is no negative effect, but for high-rise buildings, the stairs are not suitable, because people's legs, feet, and knees can't stand it when they go up to the 10th floor, and the elderly can't stand it when they are on the 4th floor. , discomfort occurs. [0003] In 1854, the great mechanic Otis invented the elevator. In 1887, the American Otis Company manufactured the world's first elevator. He has developed the knowledge of elevators, but has imprisoned the wisdom of generations of people all over the world for more than 160 years, ...

[0003] In 1854, the great mechanic Otis invented the elevator. In 1887, the American Otis Company manufactured the world's first elevator. He has developed the knowledge of elevators, but has imprisoned the wisdom of generations of people all over the world for more than 160 years, making elevators the only tool used to go up and down high-rise buildings. However, elevators are expensive, energy-consuming, poor in safety, and complex in equipment. The failure rate is high. When commuting, people often have to wait for a long time to get on the elevator. There are too many people who are late because the elevator is not working. It is too unfair. Some office buildings simply change the commute time

Especially in the case of a power outage, firefighters are needed to deliver daily necessities to the elderly, and hospitals are required to treat people with injured legs, feet, and knees. If a large-scale power outage occurs, the unusable elevator will bring disaster, so The invention of the elevator is extremely unsuitable for high-rise buildings, and an alternative tool suitable for high-rise buildings needs to be reinvented
