Device capable of conveniently vertically aligning and positioning steel concrete composite tube during tower crane hoisting

Abstract

The invention discloses a device capable of conveniently vertically aligning and positioning a steel concrete composite tube during tower crane hoisting. The device comprises a lower-layer steel concrete composite tube and an upper-layer steel concrete composite tube, wherein the lower-layer steel concrete composite tube is firmly fixed; the upper-layer steel concrete composite tube is arranged onthe top of the lower-layer steel concrete composite tube to be fixed; the lower end surface of the upper-layer steel concrete composite tube is provided with a vertical falling guidance convex structure; the inner side of the upper end surface of the lower-layer steel concrete composite tube is provided with a guidance positioning concave structure cooperated with the vertical falling guidance convex structure; multiple groups of temporary positioning devices are arranged between the upper-layer steel concrete composite tube and the lower-layer steel concrete composite tube; and each group oftemporary positioning devices independently comprises two sets of pressing type positioning devices which are independently positioned on the front side surfaces and the rear side surfaces of the upper-layer steel concrete composite tube and the lower-layer steel concrete composite tube. The device is convenient to operate, a tower crane is set free to own a great quantity of time to carry out other hoisting operations, construction progress is quickened, a pressing positioning way is adopted to position the upper-layer steel concrete composite tube so as to be convenient and quick, in addition, fine tuning can be carried out, perpendicularity and construction equality are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of prefabricated building construction, and in particular relates to a convenient vertical alignment and positioning device for a steel-concrete composite pipe hoisted by a tower crane. Background technique [0002] Prefabricated steel components or steel-concrete assemblies designed in factories or construction sites according to drawings and assembled on site are called prefabricated buildings. For prefabricated buildings with fewer floors (low floors), during construction, large-tonnage cranes are generally used to hoist the steel components or steel-concrete assemblies on the upper floor and install the steel components or steel-concrete assemblies on the lower floors. The whole process of docking requires the crane to hang the upper steel components or steel-concrete assemblies all the time. In case of strong wind, the stability will still be affected, and the steel components are always hung by the cra...

For prefabricated buildings with fewer floors (low floors), during construction, large-tonnage cranes are generally used to hoist the steel components or steel-concrete assemblies on the upper floor and install the steel components or steel-concrete assemblies on the lower floors. The whole process of docking requires the crane to hang the upper steel components or steel-concrete assemblies all the time. In case of strong wind, the stability will still be affected, and the steel components are always hung by the crane. In multi-point construction, a large number of cranes are required, and the construction cost Higher, the crane occupies a larger construction site, which also affects other operations on the construction site

For the construction of high-rise prefabricated buildings, the tower crane is used for hoisting. The tower crane hoists the steel components or steel-concrete assemblies on the upper floor and installs them on the steel components or steel-concrete assemblies that have been constructed on the lower floor. The tower crane must be hung until the upper and lower floors After the connection is reliable, another steel component or steel-concrete assembly is hoisted, which takes up a lot of working time of the tower crane and affects the efficiency of the tower crane and the progress of the project.

In addition, when the tower crane is hoisting and docking, since there is no guiding docking structure between the bottom of the steel member or steel-concrete assembly on the upper floor and the top of the steel member or steel-concrete assembly on the lower floor, it not only wastes a long time, but also the docking is prone to misalignment, error correction time consuming
