Description

Technical Field

[0001] The present invention belongs to the technical field of prefabricated wall panel installation, and particularly relates to a rapid positioning device and construction method for a prefabricated hollow shear wall. Background Art

[0002] A prefabricated building refers to a building assembled on site with prefabricated components. The advantages of this kind of building are fast construction speed, little restriction by climate conditions, labor saving and improved building quality. With the development of modern industrial technology, houses can be manufactured in batches and sets like machine production. As long as the prefabricated house components are transported to the construction site and assembled. For traditional construction, the existing exterior wall panels mainly adopt the form of masonry wall filling walls, and this construction process is complex and has high technical requirements. While using prefabricated hollow shear walls can greatly reduce the construction difficulty, but during the hoisting and positioning process of prefabricated hollow shear walls, multiple workers are required to cooperate to control the horizontal position and descending speed of the prefabricated hollow shear wall, and smoothly and accurately place the prefabricated hollow shear wall on the floor slab. This process consumes a lot of time and thus affects the construction efficiency. Summary of the Invention

[0028] As a preferred embodiment, the first positioning component further includes: a back plate 10, the back plate 10 is detachably fixed at the rear end of the base 1, and the back plate 10 is used to define the front and rear positions of the assembled hollow shear wall. The right side edge of the back plate 10 extends beyond the right side edge of the bearing plate 9, so as to ensure that the back plate 10 has enough area to fit with the assembled hollow shear wall. More preferably, the back plate 10 can be set in an inverted L shape to reduce cost expenditure.

[0029] As a preferred embodiment, when the connecting rod 4 is in a vertical state, the right side edge of the correction plate 5 is located between the right side edge of the base 1 and the right side edge of the bearing plate 9, ensuring that the right side of the base 1 does not interfere with the lowering of the shear wall. A limit block 11 is arranged on the side of the rack 7 away from the gear 3, a clamping block 12 is arranged at the bottom end of the limit block 11, a wedge-shaped groove 13 is opened on the side of the clamping block 12 away from the rack 7, a clamping groove 14 matched with the clamping block 12 is opened at the top end of the base 1, and a locking mechanism matched with the wedge-shaped groove 13 is arranged on the side of the clamping groove 14 away from the rack 7.
