Prefabricated assembly type stairway

Abstract

The invention relates to a prefabricated assembly type stairway. The prefabricated assembly type stairway comprises a stairway body, the stairway body is provided with a plurality of steps, each step is provided with a horizontal plane and a vertical plane, each horizontal plane is provided with a pedal, the side, close to the included angle of the adjacent steps, of each pedal is hinged to the corresponding step, and a limiting assembly used for limiting the position of the pedal is arranged between each pedal and the corresponding step. According to the prefabricated assembly type stairway, by arranging the pedals with the deflectable angles and the limiting assemblies, the angle of the horizontal position of each pedal can be adjusted, so that it is ensured that the foot landing point is located at the horizontal position when people go up and down stairs, the dynamic balance feeling of people is improved, and the safety coefficient of going up and down stairs is improved.

Description

technical field [0001] The application relates to the field of house construction, in particular to a prefabricated staircase. Background technique [0002] With the development and requirements of housing industrialization, prefabricated buildings have been vigorously promoted. As the main vertical traffic of the building and the main channel for emergency evacuation, the prefabricated staircase is one of the main indicators of the assembly rate of the prefabricated building. [0003] The prefabricated staircase is to prefabricate the staircase first, and then install it on site, making the construction of the staircase more efficient. [0004] In view of the above-mentioned related technologies, the inventor believes that when people go up and down the stairs, people's dynamic balance sensitivity is high, so the requirements for footholds are high, and due to the problems of prefabrication accuracy and on-site actual installation accuracy Therefore, once the slope of the...

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that when people go up and down the stairs, people's dynamic balance sensitivity is high, so the requirements for footholds are high, and due to the problems of prefabrication accuracy and on-site actual installation accuracy , it is difficult to keep the horizontal surface of the stairs horizontal, so once the slope of the horizontal surface of the stairs is too large, it will easily cause people's discomfort when going up and down the stairs, and the safety factor is low
