大型预制钢结构旋转楼梯安装技术

Installation Technology for Rotating Staircase of Large Prefabricated Steel Structure

在旋转楼梯安装中应用大型预制钢结构,有利于解决传统混凝土旋转楼梯连接精度问题;其采用平台钢梁、楼梯地面安装、模拟施工管理、无支架技术方法,解决了传统的施工技术难题;将成品楼梯固定在中心轴柱上,保证了旋转楼梯的安装完整性,又具有预制效果,文中结合工程实例,分析了大型预制钢结构旋转楼梯安装技术及应用。

The application of large prefabricated steel structure in the installation of rotating stairs is conducive to solve the problem of connection accuracy of traditional concrete rotating stairs;It adopts the methods of platform steel beam, stair ground installation, simulated construction management and no support technology to solve the traditional construction technical problems;The finished stairs are fixed on the central shaft column, which not only ensures the installation integrity of the rotating stairs, but also has the effect of prefabrication.Combined with engineering examples, this paper analyzes the installation technology and application of large prefabricated steel structure rotating stairs.
