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.
一种装配式预制楼梯吊装吊架,其由角钢支架、钢丝绳、花篮螺杆、吊点连接件构成;角钢支架采用角钢焊接为矩形结构,角钢长度及焊接尺寸根据预制楼梯的吊点位置确定,在角钢支架四个角钻孔;钢丝绳上端与吊钩连接、下端穿过角钢支架上的孔后与花篮螺杆上端连接,花篮螺杆下端通过钢丝绳与吊点连接件连接,吊点连接件与预制楼梯螺纹连接;花篮螺杆由圆钢、钢套筒、螺杆组成,圆钢两端与两个钢套筒焊接,圆钢焊接间距角度120°,两端钢套筒内穿螺杆,螺杆一端焊接圆形吊环,花篮螺杆两端吊环均与钢丝绳连接,且两端钢套筒内穿的螺杆车丝为一正一反。该吊架能够保证预制楼梯在吊装过程中能精确定位、快速安装、不致发生安装歪斜及偏位。
