The invention relates to the technical field of prefabricated part lifting appliances, in particular to a prefabricated composite floor slab lifting device which comprises a lifting main hook and a prefabricated slab, a lifting ring is hung on the lower portion of the lifting main hook, a mounting box is arranged at the bottom of the lifting ring, and fixing seats are transversely arranged on the two sides of the mounting box; first sliding rails are transversely and symmetrically arranged at the bottoms of the fixing seats, the bottoms of the first sliding rails on the adjacent sides are slidably connected with the same sliding seat, lifting rods are vertically arranged at the two ends of the bottom of the sliding seat, lifting assemblies used for lifting the prefabricated plate are arranged at the bottoms of the lifting rods, and multiple sets of truss steel bars are distributed at the top of the prefabricated plate at equal intervals. And cables are symmetrically inserted into two sides of the bottom of the mounting box in a sliding manner. According to the hoisting method, hoisting of the prefabricated slab is carried out in two steps, damage to the prefabricated slab and truss steel bars can be effectively avoided through the scheme, stress points are all arranged on the prefabricated slab, long-time and long-distance hoisting operation of the prefabricated slab is facilitated, and the convenience of later use of the prefabricated slab is greatly improved.

    本发明涉及预制构件吊具技术领域,具体涉及一种预制叠合楼板的吊装装置,包括起吊主钩以及预制板,所述起吊主钩下部挂设有起重环,所述起重环底部设有安装箱,所述安装箱两侧均横向设有固定座,所述固定座底部均横向对称设有第一滑轨,相邻一侧的所述第一滑轨底部滑动连接有同一滑座,所述滑座底部两端均竖向设有吊杆,所述吊杆底部均设有用于起吊预制板的起吊组件,所述预制板顶部等距离分布有多组桁架钢筋,所述安装箱底部两侧对称滑动插设有缆绳。本发明将预制板的起吊分为两个步骤进行,该方案可以有效避免预制板以及桁架钢筋的损坏,将受力点均设置于预制板上,有利于长时间长距离的预制板吊装作业,大大提高了预制板后期使用的便捷性。
