Assembly type checkered steel plate steel stair

Abstract

The invention provides an assembly type checkered steel plate steel stair. The assembly type checkered steel plate steel stair comprises a first stair layer, a plurality of second stair layers, a plurality of rest platform layers and reinforcing stress angle steel fixed to a floor structure, wherein the rest platform layers are arranged between the first stair layer and the second stair layers, the rest platform layers are also arranged between the second stair layers, the first stair layer and the second stair layers are each provided with a plurality of steps, and a rest platform plate is arranged on the rest platform. According to the assembly type checkered steel plate steel stair, the method that all parts of the steel stair are machined in a factory is adopted, transportation cost and construction cost are reduced, the parts are directly transported to the site to be assembled in a splicing and assembly mode during construction, electric welding is not needed, and fire accidents are completely eradicated.

Description

technical field [0001] The invention relates to the field of staircase structures, in particular to an assembled checkered steel staircase. Background technique [0002] Steel stairs are a product of the industrial age and were widely used in factory buildings in the past. In recent decades, with the emergence of many high-tech style buildings, it is characterized by some aesthetic features: the extensive use of industrial metal materials and the exposure of building structural components. These characteristics are reflected in many buildings, and the steel staircase is an important element that can express its characteristics. The outdoor steel staircase of the Pompidou Center in Paris forms a perfect combination with the scaffolding-like building facade. There are various forms of steel stairs, but most of them use their stretched lines to obtain a physical rhythm contrast with the surrounding environment space. The structural support system of the steel staircase takes...

AI Technical Summary

Problems solved by technology

[0003] The steel stairs in the prior art are almost all processed by spot welding during installation. The processing requirements are high, the size is too large, the weight is heavy, the transportation cost is high, and mechanical hoisting is required for construction. The construction is very difficult, and there is a fire hazard in the on-site welding. Prefabricated construction cannot be realized, and the comprehensive cost in the overall installation process is relatively high
