摘要
针对目前混凝土结构模板设计时采用的混凝土对模板的侧压力一般都按《混凝土结构工程施工及验收规范》GB50204—1992中推荐的公式计算,通过计算推导验证了混凝土对倾斜模板的侧压力计算公式,分别取现浇混凝土及模板作为隔离体对倾斜模板及支架的受力进行了理论分析,对支撑力的不同施加方式进行了讨论,并给出了模板和支架的搭设方法。
Based on the fact that lateral pressure of concrete on formwork is calculated by the formula in Code for construction and acceptance of concrete structures GB50204--2002 during formwork design of concrete structure at present,the authors deduce and verify the formula about lateral pressure of concrete on formwork, analyze the force of inclined formwork and scaffold by selecting fresh concrete and formwork as isolated body, and discuss different application mode for holding power, erection method of formwork and scaffold is given.
