Problems solved by technology

[0004] However, it is more dangerous to disassemble and modify systems one by one at high altitude in this way, and the dismantled components need to be transported to the ground by tower crane, which takes a long time and needs further improvement

Embodiment Construction

[0032] In order to facilitate the understanding of the present invention, the following will be described in conjunction with the accompanying drawings and embodiments.

[0033] see Figure 2 to Figure 4 , indicating that the present invention provides a method for dismantling and modifying a jacking platform at high altitude.

[0034] Such as figure 2 As shown, the jacking platform A is set above the core tube B, and the jacking platform A mainly includes a truss system 10, a supporting power system 20, a hanger 30 and a formwork system 40, wherein the truss system 10 is located at the top of the jacking system. At the top of the platform A, the truss system 10 is mainly connected and assembled on the core tube B through the supporting power system 20. The supporting power system 20 is used to support and apply power to lift the jacking platform A up with the core tube B and climbing; the hanger 30 is hung under the truss 10, and the hanger 30 is arranged on both sides of ...

Abstract

The invention provides a high-altitude demounting and modifying method of a jacking platform. The method comprises the steps that (a) in the high altitude, demounting and modifying units on the jacking platform are overall hoisted down through a tower crane; (b) after being close to the ground, the demounting and modifying units are exchanged and hanged to a truck crane from the tower crane; and (c) demounting work of the demounting and modifying units is manually carried out on the ground from bottom to top. Thus, by means of the method of combining high-altitude overall hoisting and ground demounting, the demounting and modifying difficulty of all systems forming the jacking platform in the high-altitude state is effectively reduced, meanwhile, occupancy on the tower crane is effectively reduced, and tower construction is prevented from being influenced.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a high-altitude demolition method for a jacking platform. Background technique [0002] With the advancement of science and technology and the improvement of construction technology, there are more and more super high-rise large buildings. Super high-rise construction often adopts an integral jacking platform for construction, while in super high-rise structures, a core tube and outer steel frame structure system is used. The core tube The section will gradually change with the increase of construction height, such as figure 1 shown; when the section of the core tube changes to a certain extent (for example figure 1 Section of the fifth stage), the overall lifting platform truss system, hanger system, formwork system, etc. need to be dismantled and modified according to the change of the wall. Since the height of the demolition and modification generally reaches mo...
