某现浇钢筋混凝土翘曲屋面工程实践

Practice of a reinforced concrete warped roof structure

随着我国建筑业的蓬勃发展,越来越多建筑追求造型美观、独特。本项目为大型公共建筑,裙房屋面采用翘曲屋面结构,呈起伏山丘状造型。本文结合实际工程,介绍了翘曲屋面设计中荷载取值、结构布置、节点构造,提出了结构建模计算方法,比较了平屋面和翘曲屋面受力差别;针对翘曲屋面特点和难点,提出了施工中模板支撑方法及混凝土浇筑技术要点。

With the rapid development of Chinese construction industry,more and more buildings are pursuing aesthetic modeling and unique design.The project introduced is a large public building with warped roof structure and undulating hill-like shape.Combining with it,this paper introduces the load value,structure arrangement and node structure in the design of warped roof,puts forward the calculation method of structure modeling,and compares the difference of force between flat roof and warped roof.According to the characteristics and difficulties of warped roof,the method of formwork support and key technical points of concrete pouring in construction are put forward.
