Combined type telescopic sleeve jacking device and method

Abstract

The invention belongs to the technical field of construction engineering construction, and particularly relates to a combined type telescopic sleeve jacking device and method. The device solves a series of problems that in high-rise and super high-rise building concrete cylinder construction, a traditional climbing formwork system is complex in a power system, large in transmission mechanism number, poor in narrow cylinder space adaptability, low in combined construction flexibility and the like. The combined type telescopic sleeve jacking device comprises a plurality of jacking unit modules,a horizontal jacking frame, an upper supporting frame, a lower supporting side frame and a plurality of longitudinal connecting beams, wherein each unit jacking module comprises a jacking oil cylinderand a telescopic sleeve frame; the jacking oil cylinders are arranged at the center positions of the telescopic sleeve frames, and the upper ends of the jacking oil cylinders are connected with the horizontal jacking frame; and the jacking oil cylinders penetrate through gaps between the longitudinal connecting beams of the upper supporting frame, and the lower ends of the jacking oil cylinders are connected with the lower supporting frame. By providing a single-oil-cylinder jacking module device with a telescopic sleeve frame, formwork system jacking operation can be independently carried out, multi-module combined jacking can be carried out according to large-space cylinder construction needs, and large-load three-dimensional operation is achieved.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, in particular to a combinable telescopic sleeve jacking device and a method thereof. Background technique [0002] During the construction of the inner tube of the high-rise and super-high-rise concrete core tube structure, in order to improve work efficiency, the climbing formwork system with its own power system is often used for inter-story climbing construction, such as electric lifting scaffolding, hydraulic climbing platform, etc. Electric lifting scaffolds use motor-driven wire rope pulley blocks to lift the frame body, which improves the automation level of the formwork to a certain extent, but manual intervention is still required during the lifting process, and the safety defense line is single. When the process encounters obstacles, the steel wire rope may break, causing the whole frame to fall from a high altitude, posing certain safety risks. The hydraulic climbing ...

Problems solved by technology

[0005] The invention provides a combinable telescopic sleeve jacking device and method, aiming to solve the problem of complex power system of traditional climbing formwork system, large number of transmission mechanisms, and narrow cylinder space in the construction of concrete cylinders in high-rise and super high-rise buildings. For problems such as poor adaptability and low flexibility in combined construction, we provide a single-cylinder jacking module device with a telescopic sleeve frame, which can independently carry out the lifting operation of the formwork system, and can also carry out multi-module combined jacking according to the construction needs of large-space cylinders. It can realize large-load three-dimensional operation, reduce construction cost investment, ensure the safety of super high-rise formwork climbing construction, and improve the construction efficiency of concrete core tube structure
