The invention relates to the technical field of laminated slab hoisting, in particular to a PC laminated slab hoisting positioning structure and a construction method.The PC laminated slab hoisting positioning structure is characterized in that a hoisting platform is connected to a hoisting terminal of a crane body, a center platform is elastically connected to the middle of the bottom end of the hoisting platform, and a first hook is connected to the bottom end of the center platform through a first rotary connecting device; a second rotary connecting device is arranged on the side of the bottom end of the hoisting platform, a second hook is connected to the bottom end of the second rotary connecting device, the first hook hooks a truss rib hoisting point of the laminated slab, and the L-shaped inner side end face of the second hook hooks a corner of the laminated slab; the first rotary connecting device drives the first hook to rotate and unhook automatically, the second rotary connecting device drives the second hook to rotate and unhook, the arc-shaped outer end face of the rotating second hook abuts against a reinforcing bar on the side to drive the laminated slab to be subjected to automatic fine adjustment, movement and positioning, the problem that the position is manually corrected and adjusted is solved, and operation is convenient.

    本发明涉及叠合板吊装技术领域,具体涉及一种PC叠合板吊装定位结构及施工方法,通过连接于吊机本体起吊终端的吊装平台,吊装平台底端中间位置弹性连接有中心平台,中心平台底端通过第一转动连接装置连接有第一挂钩,吊装平台底端边侧位置设有第二转动连接装置,第二转动连接装置底端连接有第二挂钩,第一挂钩吊钩叠合板的桁架筋吊点处,第二挂钩的L形内侧端面吊钩叠合板的边角处,吊机本体将叠合板吊装落位后,通过第一转动连接装置带动第一挂钩自动转动脱钩,通过第二转动连接装置带动第二挂钩转动脱钩,转动中的第二挂钩的弧形外端面抵接旁侧的配筋,用以带动叠合板自动微调移动定位,减少了人工手动修正调整位置的问题,操作方便。
