The invention relates to a precast part, in particular to a precast concrete component. The precast concrete component comprises a circular seat, a rectangular hole, a rectangular insertion groove, ahoisting shaft, a rotating sheet, limiting rings, a hook ring, a cuboid block and a concrete plate. The precast concrete component is convenient to connect with a hoisting machine, so that the hoisting machine can integrally move the precast concrete component. The circular seat is arranged in the center of the upper side of the concrete plate; the rectangular hole is formed in the upper side of the circular seat; the rectangular insertion groove is formed in the lower side of the circular seat; the rectangular insertion groove and the rectangular hole are arranged to form a cross; the lower end of the hoisting shaft is fixedly connected with the cuboid block; the cuboid block penetrates through the rectangular hole, rotates by 90 degrees, and is inserted into the rectangular insertion groove; the upper portion of the hoisting shaft is rotationally connected with the rotating sheet; the upper portion of the hoisting shaft is fixedly connected with the two limiting rings; the two limiting rings are attached to the upper side and lower side of the rotating sheet respectively; and the hook ring is arranged on the upper portion of the rotating sheet.
本发明涉及一种预制构件,更具体的说是一种混凝土预制构件,包括圆座、矩形孔、矩形插槽、起吊轴、转片、限位环、勾环、长方体块和混凝土板,本发明便于连接起吊机,便于用起吊机整体移动。所述混凝土板的上侧中心设置有圆座,圆座的上侧设置有矩形孔,圆座的下侧设置有矩形插槽,矩形插槽与矩形孔呈十字状设置,起吊轴的下端固定连接有长方体块,长方体块从矩形孔穿过转动九十度后插入矩形插槽,起吊轴的上部转动连接有转片,起吊轴的上部固定连接有两个限位环,两个限位环分别与转片的上下两侧贴合,转片的上部设置有勾环。
