Hoisting equipment for fabricated building construction

Abstract

The invention relates to the field of fabricated buildings, in particular to hoisting equipment for fabricated building construction, and aims to solve the following technical problems: when an existing hoisting device is used for hoisting a prefabricated stair with differently-spaced anchor points, cables are in an inclined state, the stability is low, and meanwhile, the prefabricated stair can hardly be adjusted to be horizontal; and when sleeved with the prefabricated stair through the existing hoisting device, four reserved reinforcement bars on a building cannot be aligned simultaneously. The hoisting equipment for fabricated building construction comprises a supporting plate, a hoisting assembly, a hole aligning assembly, a grouting assembly, a control screen and the like, wherein the hole aligning assembly is fixedly connected with the grouting assembly. In the use process, the hoisting equipment automatically adapts to the differently-spaced anchor points, so that the prefabricated stair can be hoisted and adjusted to be in a horizontal state; the positioning operation on four reserved holes of the prefabricated stair can be achieved simultaneously; the phenomenon that part of the reversed reinforcement bars on the building are crushed by the prefabricated stair during assembly can be prevented; and furthermore, the reversed holes of the prefabricated stair can be automatically filled 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
