The invention discloses a reinforcement cage hoisting construction method, which belongs to the technical field of reinforcement cage hoisting, and comprises the following steps: S1, commanding a main hoist and an auxiliary hoist to be in place by a hoisting worker; s2, arranging lifting points; s3, performing'trial hoisting 'work before formal hoisting; s4, the main hoist is lifted upwards, and the auxiliary hoist is matched; s5, after the reinforcement cage is lifted to a certain height, the reinforcement cage is stably stressed, and the auxiliary crane is matched with the main crane to hoist and straighten the reinforcement cage; s6, the main crane hoists the reinforcement cage to walk to the position near the groove section, and the reinforcement cage is lowered to the position where the steel plate is placed; and S7, the main crane continues to put the reinforcement cage into the groove till the reinforcement cage is placed by all the carrying poles. According to the method, the positions of transverse and longitudinal lifting points are reasonably determined when different types of reinforcement cages in a linear shape, a right-angle L shape and the like are lifted in the step S2, so that the balance of structural stress of the reinforcement cages in the lifting process is guaranteed, the deformation possibility is reduced, the L-shaped reinforcement cages are reinforced by additionally arranging herringbone inclined struts and inclined pull rods, and the lifting safety is improved.
本发明公开了一种钢筋笼吊装施工方法属于钢筋笼吊装技术领域,包括,S1:起重工指挥主吊和副吊两台吊车就位;S2:吊点布置;S3:正式吊放前先应进行“试吊”工作;S4:主吊向上提,副吊配合;S5:提升到一定高度后,钢筋笼受力稳定,副吊配合主吊进行钢筋笼吊装回直;S6:主吊机吊装钢筋笼行走至槽段附近,将其下放至搁置钢板处;S7:主吊车继续下放钢筋笼入槽,直到钢筋笼被所有扁担搁置。本发明通过S2中在吊装“一”形、直角“L”形等不同类型的钢筋笼时,合理确定横向和纵向吊点的位置,从而保证了钢筋笼在吊装过程中结构受力的平衡,减小了变形的可能性,对于“L”型钢筋笼,还通过增设“人字”斜撑和斜拉杆进行加强,提高吊装的安全性。
