The invention belongs to the technical field of building construction, and discloses a precast concrete lifting appliance which comprises a fixed plate, guide rails are fixedly mounted on the outer side face of the fixed plate at equal angles, a movable seat is arranged above the fixed plate, limiting blocks are symmetrically mounted on the outer side face of the movable seat, and limiting guide grooves are symmetrically formed in the top end of the fixed plate. Through up-down limiting between a limiting block and a limiting guide groove, when a threaded rod rotates, a movable seat can be driven to move up and down, when the movable seat moves downwards, a connecting rod can deflect towards the outer side, the included angle between the connecting rod and the movable seat is increased, and a guide block is driven to move relative to a guide rail; at the moment, the installation assemblies at the bottom ends of the guide blocks move along with the guide blocks, the multiple installation assemblies are moved to the outer side face of the prefabricated part, the installation assemblies can be finely adjusted according to the length and width of the prefabricated part after adjustment is completed, rapid adjustment and installation of the concrete prefabricated part are achieved, and the hoisting efficiency is improved.

    本发明属于建筑施工技术领域,且公开了混凝土预制件吊具,包括固定板,所述固定板的外侧面等角度固定安装有导轨,所述固定板的上方设有活动座,所述活动座的外侧面对称安装有限位块,所述固定板的顶端对称安装有限位导向槽。本发明通过通过限位块与限位导向槽之间进行上下限位,当螺纹杆发生旋转时,此时即可带动活动座上下位移,当活动座向下位移时,此时连杆即可朝外侧进行偏转,连杆与活动座之间的夹角随之增加,并带动导向块相对导轨位移,此时导向块底端的安装组件随之位移,将多个安装组件位移至预制件的外侧面,完成调整后可根据预制件的长宽对安装组件进行微调,实现混凝土预制件的快速调整安装,提高吊装效率。
