Problems solved by technology

[0005] The technical problem to be solved by the present invention is that the effective load capacity of the existing super high-rise building is insufficient or the self-weight of the platform is too large. When jacking up, the connection between the frame body and the building structure needs to be specially designed and the main body of the building must be modified so that each frame body The time for jacking preparation and jacking operations is too long, and the effective working space is insufficient, which is not conducive to construction and results in low efficiency. The purpose is to provide a comprehensive formwork system for super high-rise building construction, which has better bearing capacity , light weight, low center of gravity, better structural safety, open construction work surface, the shortest preparation time and lifting time for each climb, and the highest work efficiency. Compared with the above systems in the construction of standard floors of super high-rise buildings, the construction period can be saved by more than one day. After the completion, it can be reused in the construction of other super high-rise and ordinary high-rise buildings with minimal modification, and the comprehensive economic benefits are unmatched by existing systems

Embodiment 1

[0071] like Figure 1 to Figure 5 As shown in the figure, the comprehensive formwork system for super high-rise building construction includes a climbing system 17 of a three-dimensional structure formed by a plurality of climbing formwork units 21 in turn. Jacking system 16, and a space for pouring concrete walls is formed between the climbing system 17 and the jacking system 16. Both the climbing system 17 and the jacking system 16 can move in a vertical direction, and the climbing formwork unit 21 is located in a three-dimensional structure The climbing mold units 21 on the same side wall are all corresponding to the jacking unit 20 close to the side wall and can move synchronously or separately. The vertical adjusting device 30 and the horizontal adjusting device 32 are installed on the jacking unit to adjust the vertical position respectively. It is positioned with the positioning connection point at the horizontal position, and each jacking unit is provided with several ...

Embodiment 2

[0073] like Image 6 , Figure 7As shown, on the basis of Embodiment 1, the jacking unit 20 includes a lower support frame 11 and an upper support frame 7, and the upper support frame 7 is arranged directly above the lower support frame 11, and the upper support frame 7 is installed with a hydraulic Cylinder 3, the hydraulic cylinder 3 is provided with an oil rod 8, the bottom of the oil rod 8 is fixed with the lower support frame 11 after passing through the upper support frame 7, when the lower support frame 11 or the upper support frame 7 is the fulcrum, the upper support frame 7 Or the lower support frame 11 can move vertically under the action of the hydraulic cylinder 3 and the oil rod 8, and at the same time the lower support frame 11 can be inserted into the upper support frame 7, and the upper support frame 7 and the lower support frame can pass through the upper support frame 7 and the lower support frame when lifting. The racks 11 are respectively used as fulcrums ...

Embodiment 3

[0082] like Figure 10 , Figure 11 and Figure 12 As shown, on the basis of the above-mentioned embodiment, since there are two conditions that need to be adjusted during jacking, this solution has two adjustment functions. This adjustment is generally used when there is a change in the lifting space; the other is to adjust the positioning wheel 33 to move horizontally. This adjustment is mainly used when the wall surface is uneven to maintain the pressing state of the wall surface. And the bearing force can prevent tilting. The system has the function of adjusting the size range at the same time, which ensures the stability of the system during jacking.

[0083] When it is used, according to the required adjustment range, first perform a large-scale adjustment, move the mounting plate 39 to the position of the support plate 37, and after reaching the appropriate position, insert four high-strength bolts into the threaded holes to form a fixation, and then rotate. The scre...

Abstract

The invention discloses a comprehensive formwork system for super high-rise building construction. The comprehensive formwork system for super high-rise building construction comprises a climbing system of a stereoscopic structure, and the climbing system is formed by climbing formwork units in an enclosure mode. A jacking system composed of jacking units is arranged inside the stereoscopic structure. A space where steel structures and steel bars are installed and a concrete wall is poured is formed between the climbing system and the jacking system. The climbing system and the jacking system can move in the vertical direction. The climbing formwork units correspond to the jacking units close to the side wall separately and can move synchronously or separately with the jacking units. Each jacking unit is provided with a vertical adjusting device and a horizontal adjusting device which are used for positioning position junctions in the vertical direction and the horizontal direction correspondingly. Each jacking unit is internally provided with a plurality of sets of tensioning devices for improving structure stability. The formwork system is low in dead weight, low in center of gravity and good in structure safety, the construction operating surface is broad, the preparation time and lifting time for each climbing are the shortest, the working efficiency is the highest, and in standard floor construction of a super high-rise building, the formwork system can shorten the construction period by one day or over compared with other systems.

Description

technical field [0001] The invention relates to a super high-rise building construction technology, in particular to a comprehensive formwork system for super-high-rise building construction. Background technique [0002] The formwork system for the construction of super high-rise buildings around the world mainly includes the DOKA formwork system used in the 828-meter-high world's tallest building completed in 2010, the Burj Khalifa in Dubai, United Arab Emirates, which represents the highest level of super high-rise building construction in the world; The formwork systems that are widely used in the construction of super high-rise buildings and are among the world's leading technologies include the overall climbing steel platform formwork system of Shanghai Construction Engineering and the large-top formwork system of China Construction. [0003] The disadvantage of the former is that the platform has insufficient effective bearing capacity and cannot meet the requirements...
