The invention relates to a prefabricated bridge deck slab hoisting assembly, a hoisting tool and a using method, the prefabricated bridge deck slab hoisting assembly comprises four hoisting units, every two hoisting units form one group and are divided into two parallel groups, the two hoisting units of each group are oppositely arranged in parallel, and each hoisting unit comprises a fixed pulley block, a lower hoisting point steel wire rope and two lower hoisting point lifting lugs; the two lower lifting point lifting lugs are arranged at intervals, the fixed pulley blocks are installed on the lower lifting point lifting lugs, the two ends of the lower lifting point steel wire rope penetrate through the fixed pulley blocks at the positions of the two lower lifting point lifting lugs respectively, vertically extend downwards and are used for being connected with a prefabricated bridge deck slab to be lifted, and the lower lifting point steel wire rope between the two lower lifting point lifting lugs is parallel to the horizontal plane. Through the application, the stress of the prefabricated bridge deck slab to be hoisted in the hoisting process can be effectively dispersed, so that the tensile force borne by each pre-buried hoisting point is more uniform, and the cracking risk of the concrete prefabricated bridge deck slab in the hoisting process is effectively avoided.
本申请涉及一种预制桥面板吊装组件、吊具及使用方法,包括四个吊装单元,每两个吊装单元为一组,分为并列的两组,且每组的两个吊装单元相对且平行设置,每个吊装单元包括定滑轮组、下吊点钢丝绳和两个下吊点吊耳,两个下吊点吊耳之间设有间距,且所述定滑轮组安装于所述下吊点吊耳,所述下吊点钢丝绳的两端分别穿过两个下吊点吊耳处的定滑轮组,并垂直向下延伸,用于连接待吊预制桥面板,且两个下吊点吊耳之间的下吊点钢丝绳平行于水平面。通过本申请,可以有效地分散待吊预制桥面板在吊装过程中的受力,使各预埋吊点所承受的拉力更加均匀,从而有效避免了混凝土预制桥面板吊装过程开裂风险。
