摘　　要：为保障大跨度坡屋面混凝土结构施工质量,文中结合某体育馆项目,对大跨度坡屋面混凝土结构高大支模施工技术进行详细分析。结果表明,立杆间距加密结合剪刀撑、扫地杆及连墙件等加固措施能有效提升架体的稳定性;采用木楔填充主次龙骨、托架与主龙骨之间的空隙,能有效解决坡屋面龙骨易滑动的问题;采用L形附加板对模板节点处加固,能有效避免漏浆及构件偏位的问题。In order to guarantee the construction quality of large-span slope roof concrete structure,this paper analyzes the construction technology of large-span slope roof concrete structure with tall support forms in detail in conjunction with a gymnasium project.The results show that the stability of the frame can be effectively improved by the combination of the spacing of the vertical poles and the reinforcement measures such as scissors bracing,sweeping bar and wall connecting parts.Using wooden wedge to fill the gap between the primary and secondary keel,bracket and main keel can effectively solve the problem of sliding keel of slope roof.The use of L-shaped additional plate to strengthen the joint of the template can effectively avoid the problems of slurry leakage and component deflection.
