Prefabricated wallboard external hanging rack prefabricated hole and hoisting device

Abstract

The invention discloses a prefabricated wallboard external hanging rack prefabricated hole and a hoisting device. The prefabricated wallboard external hanging rack prefabricated hole and the hoistingdevice comprises a base and a positioning nut fixed on a die table surface, a through pipe used for forming a perforated hole in a prefabricated wallboard and a hoisting part used for horizontal hoisting. According to the prefabricated wallboard external hanging rack prefabricated hole and hoisting device, the through pipe is connected by a screw rod and then is fixed by rotaitng the screw rod through an electric wrench to the position of a positioning nut, the screw rod is continuously rotated to move downwards when concrete of a prefabricated wallboard component reaches initial setting afterproduction, a reaction force is generated to eject the through pipe upwards so as to enable the through pipeto be loosened, the through pipe is dismantled, a required outer hanging frame through holeis formed, and the problem of inaccurate through hole positioning is solved. After the screw rod and the through pipe are disassembled, the horizontal hoisting part is installed and lifted at the same position without using an additional embedded horizontal hosting part the hoisting part can be repeatedly used, and the embedded hoisting part can only be used once, so that the hoisting cost is reduced, and the use is convenient.

Description

technical field [0001] The invention relates to the field of construction, in particular to a prefabricated wall board external hanger with reserved holes and a hoisting device. Background technique [0002] At present, my country's prefabricated integral concrete structures mainly include prefabricated integral frame structures and prefabricated integral shear wall structures, among which prefabricated integral shear wall structures are the most widely used. Since the exterior walls of this structural system are mostly prefabricated concrete wall panels, the external protection mostly adopts assembled external hangers, and the assembled external hangers are fixed by bolts and prefabricated wall panels. Leave holes for the external hanger to meet the installation needs of the external hanger. In addition, in order to improve production efficiency, some prefabricated component manufacturers use flat hanging demoulding when producing prefabricated wall panels, and pre-embedded...

AI Technical Summary

Problems solved by technology

[0003] At present, the prefabricated wall panel hangers are mostly made of PVC pipes or conical iron parts with demoulding chamfers. When PVC pipes are used, the workload of cleaning PVC pipes is relatively large when the holes are sealed later. Conical pipes are used. When making iron parts, the cost of conical iron parts is relatively high. In addition, the embedded parts used for the flat hanging and demoulding of prefabricated wall panels need to be embedded in the prefabricated components. The amount of embedded parts is large and the cost is high
