The invention discloses a precast concrete member steel strand lifting point system supporting multiple lifting modes. The precast concrete member steel strand lifting point system supporting the multiple lifting modes comprises a first steel strand, first end plates and a limiting assembly, wherein the middle part of the first steel strand is bent to form an annular lifting point; two ends of thefirst steel strand extend toward the inner part of a precast concrete member and are respectively fixedly provided with one first end plate; the two first end plates are embedded into a precast concrete member at an interval; a sleeve ring is arranged in the middle of the limiting assembly and is arranged on the lifting point in a sleeving way; and the limiting assembly is embedded into a precastconcrete member. With the structure, lifting can be carried out conveniently, and the multiple lifting modes can be borne, so that the construction efficiency is improved, and a mechanical performance of a precast member cannot be affected; and in addition, multiple lifting point systems can be arranged on one same precast concrete member so as to form a lifting point system group.

    本发明公开了一种支持多种吊装方式的预制混凝土构件钢绞线吊点体系,包括第一钢绞线、第一端板及限位组件;所述第一钢绞线的中部弯折形成环形的吊点,所述第一钢绞线的两端向预制混凝土构件的内部延伸并分别固设有一所述第一端板,两个所述第一端板间隔埋设于预制混凝土构件内;所述限位组件的中部设有套环,所述套环套设于吊点处,所述限位组件埋设于预制混凝土构件内。上述结构使得吊装方便,能够承担多种吊装方式,从而提高了施工效率,不影响预制构件本身的力学性能,且该吊点体系可在同一预制混凝土构件上设置多个,形成吊点体系组。
