Assembled building modular stair structure and construction process thereof

Abstract

The invention discloses an assembled building modular stair structure and a construction process thereof. The structure comprises a stair platform, stair main body frames and stair steps, there are the two stair main body frames, the stair main body frames are uniformly provided with stair step cooperating blocks, the stair step cooperating blocks are movably provided with the stair steps, a rotating sleeve is movably sleeved with a rotating shaft of an upper platform, a movable slot is internally fixedly provided with a fastening bolt, a spring fixing seat is fixedly provided with a shock absorbing spring, and one end, away from the spring fixing seat, of the shock absorbing spring is fixedly connected with the stair main body frames. The stair main body frames are two separate frames, stair slopes can be adjusted according to actual needs, within different floor heights, the stair main body frames can be used without changing a structure, the damage of a stair structure caused by lateral and longitudinal vibrations is effectively reduced, loading and unloading are facilitated, and the structure is energy-saving and environmental-protection, and is suitable for promotion.

Description

technical field [0001] The invention relates to the technical field of prefabricated buildings, in particular to a modular staircase structure of a prefabricated building and its construction technology. Background technique [0002] Buildings assembled from prefabricated parts and components on site are called prefabricated buildings. According to the form and construction method of prefabricated components, they can be divided into five types: block building, plate building, box building, skeleton plate building and rising plate building. Different from the traditional pouring and forming building method, the prefabricated building has the characteristics of energy saving, environmental protection, formwork saving, and shortening the construction period. As an important part of the prefabricated building, the prefabricated staircase is the main vertical transportation and emergency evacuation of the building. As the main channel, it has an important impact on the normal us...

AI Technical Summary

Problems solved by technology

[0004] Although it solves the problem of difficult construction of traditional stairs, there are still obvious defects in the use of the above-mentioned prefabricated stairs: 1. The inclined ladder plate of the above-mentioned device is an integral structure, which is relatively large in size, difficult to move and install, and has a heavy weight. 2. The above-mentioned device can only be used in corridors with a certain slope through the fastening connection of the inclined ladder board and the horizontal ladder board. The installation requirements are strict, and the slope of the stairs cannot be changed according to the needs; The structure is shock-absorbing up and down. Since the damage to the building caused by the earthquake is mainly caused by lateral vibration, the shock-absorbing effect of the device is relatively limited when an earthquake occurs.
