Integrated formwork system for construction of super high-rise building

Abstract

An integrated formwork system for construction of a super high-rise building, comprising a climbing system in a stereoscopic structure formed by a successive enclosure of a plurality of climbing formwork units, a jacking system formed by a plurality of jacking units arranged side by side being disposed in the stereoscopic structure, and a working space formed between the climbing system and the jacking system, wherein the climbing formwork units located at a same side wall of the stereoscopic structure all correspond to the jacking units adjacent to the side wall and are capable of moving synchronously or separately, the jacking units are provided thereon with a vertical adjusting device and a horizontal adjusting device, and a plurality of groups of tensioning devices are disposed in each of the jacking units. Such formwork has light deadweight, a low gravity center, good structural safety, a broad construction work plane.

Description

FIELD OF THE INVENTION[0001]The present disclosure relates to the construction technology for super high-rise buildings, and more particularly to an integrated formwork system for construction of a super high-rise building.BACKGROUND OF THE INVENTION[0002]The formwork systems for construction of super high-rise buildings in the world mainly include the DOKA formwork system used by the world's tallest building, i.e. the 828-meter-high Burj Khalifa Tower in Dubai, UAE, which is completed in 2010 and represents the highest level of the current super high-rise building construction; and the world's leading formwork systems commonly used for domestic super high-rise building construction include the integral lifting steel platform formwork system of Shanghai Construction and the large top form formwork system of China State Construction.[0003]The former has the disadvantage that the platform has an insufficient effective load, which cannot meet the requirements of installing spreaders an...

AI Technical Summary

Benefits of technology

[0005]The technical problems to be solved by the present disclosure are that during the traditional construction of super high-rise buildings, the effective load is insufficient or the platform has the excessively large deadweight, during jacking operation the connection between the formwork and the building structure needs to be specially designed and the major structure of the building is required to be changed, causing the time for the preparation and jacking operation for each formwork jacking to be extremely long, and the insufficient effective working space is unfavourable for construction and causes low efficiency. The present disclosure aims to provide an integrated formwork system for construction of a super high-rise building, which has a better bearing capacity, light deadweight, a low gravity center, better structural safety, a broad construction work plane, shortest preparation time and lifting time for each climbing and highest working efficiency; and compared with the aforementioned systems, the construction period for the construction of the standard floors of the super high-rise building can be shortened by one or more days, and after the construction is completed, the present disclosure can be reused in construction of other super high-rise and ordinary high-rise buildings with only a few changes, having comprehensive economic benefits unmatched by the traditional systems.

Problems solved by technology

The technical problems to be solved by the present disclosure are that during the traditional construction of super high-rise buildings, the effective load is insufficient or the platform has the excessively large deadweight, during jacking operation the connection between the formwork and the building structure needs to be specially designed and the major structure of the building is required to be changed, causing the time for the preparation and jacking operation for each formwork jacking to be extremely long, and the insufficient effective working space is unfavourable for construction and causes low efficiency.

1. In addition to the spreaders, the control operation house, the fire water tank and the like are arranged on the top layer; and most construction hoists reach the top layer directly, which significantly reduces the valuable space for working plane and materials stacking in the top layer, and increases the probability of the safety accidents caused by interference and collision as the steel members and materials are lifted into position by the tower crane after the construction hoist reaches the top layer, obviously reducing the effect of lifting large steel members into position.
