高大模板支撑结构设计方法要点

Analysis of Design and Calculation Method for High and Large Formwork Support Structure

对高大模板支撑结构在结构计算模型、荷载计算方法和混凝土浇筑相关荷载的特性等方面进了分析研究。依据《建筑施工模板安全技术规程》,并对照品茗软件的现行方法,提出模板支撑结构的设计是由模板支撑架的设计计算与诸多限定、构造要求共同构成的方法体系;荷载计算宜采用不考虑上一级结构连续性的方式进行;混凝土浇筑相关各荷载除自重外均具有作用范围小而且集中作用的特点。

High and large formwork support structure is analyzed,which including calculation model of the structure,calculation method of load and characteristic analysis of the load related to pouring of concrete.According to the technical code for safety of forms in construction and comparing with current practice of Pinming Software,several summary are presented as follows.The design of formwork structure is a method system composed of calculation of formwork support structure and many restriction and construction requirement.Structural continuity is not suitable to be considered in load calculation of upper stage structure.Small range of action and concetrated acting are the characteristics of the load related to concrete pouring but dead weight.
