The On-Site Lifting and Construction Techniques for Prefabricated Concrete Components in Prefabricated Buildings
At present,the on-site lifting support structures of precast concrete components are mostly set as inde-pendent forms,which affects the daily lifting construction progress and leads to the increase of displacement val-ue.Therefore,the design and verification analysis of the field lifting construction technology of prefabricated con-crete components are proposed.According to the current construction requirements and standard changes,lifting preparation,lifting points are set up,and multi-level methods are adopted to speed up the daily lifting construc-tion progress,realize the installation of multi-level steel pipe rack support structure,correct the lifting position of prefabricated components,and calculate the balance control precision.On this basis,the prefabricated members are tied and lifted,and finally the hoisting,falling,reinforcement and later maintenance of the prefabricated com-ponents are adopted to realize the lifting construction.The test results show that:after measurement,the current displacement value is controlled below 0.5 m,which shows that the lifting construction technology designed in this paper is more efficient and has practical application value.
