滑模装置主要包括操作平台、模板系统和液压滑升系统等三个组成部分。烟囱滑模平台多为由辐射梁、下拉杆和内环梁等构成的辐射状的空间钢结构(图1),要求具有足够的强度、刚度和稳定性。本文分析对施工荷载的取值和荷载组合及平台的计算方法并提出具体建议。 The sliding mode device mainly includes three components such as an operation platform, a formwork system, and a hydraulic sliding system. The chimney sliding platform is mostly a radial space steel structure (Fig. 1) composed of a radiating beam, a pull-down rod, and an inner ring beam, and requires sufficient strength, stiffness, and stability. This paper analyzes the value and load combination of the construction load and the calculation method of the platform and puts forward specific suggestions.
