The invention relates to an
assembly type prefabricated stair hoisting hanger, which consists of an angle steel bracket, a steel
wire rope, a basket screw and a hoisting point connecting piece, the angle steel bracket adopts angle steel to be welded into a rectangular structure, the length and the
welding size of the angle steel are determined according to the lifting point position of the prefabricated stair, and four corners of the angle steel bracket are drilled; the upper end of the steel
wire rope is connected with the lifting hook, and the lower end of the steel
wire rope penetrates through a hole in the angle steel support and then is connected with the upper end of the turnbuckle, and the lower end of the turnbuckle is connected with the lifting point connecting piece through the steel wire
rope. The turn buckle screw is composed of round steel, steel sleeves and a screw, the two ends of the round steel are welded to the two steel sleeves, the
welding interval angle of the round steel is 120 degrees, the screw penetrates through the steel sleeves at the two ends, one end of the screw is welded to a round hanging ring, the hanging rings at the two ends of the turn buckle screw are connected with the steel wire
rope, and the screw penetrating through the steel sleeves at the two ends is turned in a positive and
negative mode. The hanging bracket can ensure that the prefabricated staircase can be accurately positioned and quickly mounted in the hoisting process, and mounting deflection and deviation are avoided.
