Special lifting appliance for precast concrete component and mounting method
The invention relates to a special lifting appliance for a precast concrete component and a mounting method, the special lifting appliance comprises a lifting appliance pre-arranged on a bottom die of the precast concrete component, the lifting appliance comprises a lifting rod, a lifting ring is fixedly arranged at the upper part of the lifting rod, and a steel base plate and a bottom nut are fixedly arranged at the lower part of the lifting rod; the steel base plate and the bottom nut are arranged in the stepped pit hole, the stepped pit hole comprises a first cylindrical pit hole and a second cylindrical pit hole which are sequentially arranged from bottom to top, the diameter of the first cylindrical pit hole is smaller than that of the second cylindrical pit hole, the steel base plate is arranged in the second cylindrical pit hole, and the bottom nut is arranged in the second cylindrical pit hole. The bottom nut is arranged in the first cylindrical pit hole, and the hanging rod is sleeved with a PVC pipe. A large amount of hanging ring steel can be saved, bottom operation space does not need to be reserved, and mounting and dismounting are convenient.
本发明涉及一种混凝土预制构件的专用吊具及安装方法，专用吊具包括预先设置在预制构件的底模上的吊具，所述吊具包括吊杆，所述吊杆上部固定设置有吊环，所述吊杆下部固定设置有钢垫板和底螺母，所述钢垫板和底螺母设置在台阶式坑洞内，所述台阶式坑洞包括从下到上依次设置的第一圆柱形坑洞和第二圆柱形坑洞，所述第一圆柱形坑洞直径小于第二圆柱形坑洞直径，所述钢垫板设置在第二圆柱形坑洞内，所述底螺母设置在第一圆柱形坑洞内，所述吊杆外部套设有PVC管。本发明可节省大量的吊环钢材，不需要预留底部操作空间，安装、拆除方便。
