山东齐鲁乙烯工程聚氯乙烯装置的包装仓库,建筑面积为17000多平方米,除局部有预制槽型屋面板和现浇框架外,均为折板屋盖。折板的特点是板面大而薄,平面外刚度较差,运输和吊装都是在折板非正常受力状态下进行的。为此,在运输及安装阶段,应减小折板平面的外摆度及吊装起落时的振动,防止构件 The packaging warehouse of Shandong Qilu Ethylene Engineering Polyvinyl Chloride Plant has a building area of ​​more than 17,000 square meters. All of the above are prefabricated trough roofing panels and cast-in-place frameworks. The characteristics of the folding plate are that the plate surface is large and thin, and the rigidity outside the plane is poor. Transportation and lifting are performed under the condition that the folding plate is under abnormal stress. For this reason, in the transportation and installation phase, the degree of out-of-plane tilt of the folded plate and the vibration during lifting and landing should be reduced to prevent the components.
