Device for vertical connection construction of upper-layer and lower-layer assembly type steel-concrete combined pipes

Abstract

A device for vertical connection construction of upper-layer and lower-layer assembly type steel-concrete combined pipes comprises the firmly-fixed lower-layer steel-concrete combined pipe and the to-be-fixed upper-layer steel-concrete combined pipe arranged on the top of the lower-layer steel-concrete combined pipe. A plurality of temporary positioning devices are arranged between the lower-layersteel-concrete combined pipe and the upper-layer steel-concrete combined pipe. Each temporary positioning device comprises two pressing type positioners, wherein the two pressing type positioners arelocated on the front side faces and the rear side faces of the lower-layer steel-concrete combined pipe and the upper-layer steel-concrete combined pipe correspondingly, and the two pressing type positioners are arranged in front-back symmetry. The device is novel in design and convenient to operate, liberates a large amount of time for a tower crane for other crane operation, quickens the construction progress, positions the upper-layer steel-concrete combined pipe in a pressing positioning mode conveniently and rapidly, and can ensure the perpendicularity and construction quality through fine adjustment; and by means of outer wrapped concrete, the steel-concrete combined pipes have higher fireproof performance and anti-corrosion performance and higher structural durability.

Description

technical field [0001] The invention belongs to the technical field of prefabricated building construction, and in particular relates to a construction device for vertically connecting upper and lower layers of a prefabricated steel-concrete composite pipe. 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...

Problems solved by technology

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.
