Comprehensive formwork system for super high-rise building construction

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...

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
