A hoisting device for prefabricated building construction

Abstract

The invention relates to the field of prefabricated buildings, in particular to hoisting equipment for construction of prefabricated buildings. The technical problem to be solved: when the existing hoisting device lifts the prefabricated stairs with different anchor points, the cables are in a tilted state, the stability is low, and it is difficult to adjust the prefabricated stairs to the level; the existing hoisting device puts the prefabricated stairs into the When the four reserved steel bars are on, the four steel bars cannot be aligned at the same time. A hoisting device for prefabricated building construction, including a support plate, a hoisting component, a hole-aligning component, a grouting component, a control screen, etc.; the grouting component is fixedly connected to the hole-aligning component. When the present invention is in use, it can automatically adapt to the anchor points of different distances to lift the prefabricated stairs and adjust them to a horizontal state. It also realizes the automatic positioning operation of the four reserved holes of the prefabricated stairs at the same time, which prevents the prefabricated stairs from being assembled. The phenomenon of crushing the reserved steel bars of some buildings has also been realized to automatically fill the reserved holes of prefabricated stairs with slurry.

Description

technical field [0001] The invention relates to the field of prefabricated buildings, in particular to hoisting equipment for construction of prefabricated buildings. Background technique [0002] Prefabricated building refers to the transfer of a large number of on-site operations in the traditional construction method to the factory, where the building components and accessories (such as floors, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory, and transported to the construction site. Reliable connections are assembled and installed on site. [0003] In the prior art, one of the prefabricated stairs presents a rectangular shape with four anchor points in the middle, two reserved holes in the upper installation position, and two reserved holes in the lower installation position. Existing devices hoist this type of prefabricated stairs When using cables to fix the four anchor points, and then fix the cables to the hook of the crane throug...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the existing device when hoisting this kind of prefabricated stairs, because the anchor points of different specifications of prefabricated stairs are set differently, the cables are in a tilted state after the prefabricated stairs are hoisted, which greatly increases the difficulty of adjusting the prefabricated stairs to the level, and at the same time it is stable In addition, the existing device cannot align the four reserved holes of the prefabricated stairs with the four reserved steel bars on the building, resulting in that when the prefabricated stairs are placed on the building, the edges of the reserved holes hit the four bars The phenomenon of steel bars, which in turn leads to the fragmentation of the edge of the reserved hole, greatly reduces the shortcomings of structural stability, the technical problem to be solved: when the existing hoisting device lifts prefabricated stairs with anchor points with different spacing, the cables are in a tilted state, and the stability is low At the same time, it is difficult to adjust the prefabricated stairs to the level; when the existing hoisting device puts the prefabricated stairs on the four reserved steel bars on the building, the four steel bars cannot be aligned at the same time
