摘要:
简述了钢筋混凝土筒仓结构仓顶施工所用模板支架及其施工操作平台系统,该操作平台作为满堂支撑架的搭设基础,用于承担并传递仓顶施工时的荷载.运用SAP2000 建立满堂支撑架及施工操作平台的数值模型,通过逆向推演的形式进行模板支撑架及操作平台的内力分析:先将整个仓顶分三步施工得到每一步混凝土浇筑时模板支撑架立杆底部的轴力,然后将
所得轴力作为外荷载分步作用于施工操作平台之上,可直观地看到不同混凝土浇筑阶段施工操作平台各构件的内力响应.分析结果表明:分步施工的方法能够合理地分配外荷载,避免仓顶一次施工荷载过大可能造成的施工安全隐患,钢丝绳的提拉能够减小操作平台的变形,保证施工安全.
Abstract:
 The template support frame and its construction operating platform system for roof construction of reinforced concrete silo structure is described, as the operating platform was the erection foundation to undertake and pass the loads during the roof concrete pouring. Numerical models of the template support frame and the operating platform through finite element software SAP2000 were established and their force by reverse deduction analyzed. Firstly the whole roof is divided into three steps, and the axial force at the pole’s bottom of the template support frame is obtained under each step. Secondly the axial force as external forces acting on the operating platform is retained step by step, last could retain each element’s mechanical response of the operating platform under different concrete pouring steps. Results showed that staged construction can help distribute the external loads reasonably, avoid the construction safety hazards of large loads aroused by once excessive construction. And the rope could ensure construction safety by reducing the deformation of the operating platform.
