Benefits of technology

The present invention provides an integrated formwork system for the construction of super high-rise buildings. The system has better bearing capacity, light deadweight, a low gravity center, and better structural safety. It also has a broad construction work plane and shortest preparation time and lifting time for each climbing, leading to highest working efficiency. Compared with traditional systems, the construction period for standard floors of the super high-rise building can be shortened by one or more days, and after construction is completed, the system can be reused in construction of other super high-rise and ordinary high-rise buildings with only a few changes, leading to comprehensive economic benefits.

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.

example 1

[0070]As shown in FIG. 1 to FIG. 5, an integrated formwork system for construction of a super high-rise building, comprising a climbing system 17 in a stereoscopic structure formed by a successive enclosure of a plurality of climbing formwork units 21, a jacking system 16 formed by a plurality of jacking units 20 arranged side by side being disposed in the stereoscopic structure, and a working space for mounting steel structures and steel bars and pouring concrete walls being formed between the climbing system 17 and the jacking system 16, wherein both the climbing system 17 and the jacking system 16 are capable of moving in a vertical direction, climbing formwork units 21 located at a same side wall of the stereoscopic structure in the plurality of the climbing formwork units 21 all correspond to the jacking units 20 adjacent to the side wall and are capable of moving synchronously or separately, the jacking units are provided thereon with a vertical adjusting device 30 and a horiz...

example 2

[0071]As shown in FIG. 6 and FIG. 7, based on Example 1, the jacking units 20 comprise a lower support frame 11 and an upper support frame 7, wherein the upper support frame 7 is disposed immediately above the lower support frame 11; a hydraulic cylinder 3 is installed on the upper support frame 7, wherein a cylinder pole 8 is disposed in the hydraulic cylinder 3, a bottom of the cylinder pole 8 passes through the upper support frame 7 and is fixed onto the lower support frame 11. During jacking operation the lower support frame 11 or the upper support frame 7 is as a fulcrum, either the lower support frame11 or the upper support frame 7 can move vertically under action of the hydraulic cylinder 3 and the cylinder pole 8, and the lower support frame 11 can be inserted into the upper support frame 7. When the jacking operation is carried out, the upper support frame 7 or the lower support frame 11 can be independently used as the fulcrum to realize the corresponding jacking operation...

example 3

[0079]As shown in FIG. 10. FIG. 11 and FIG. 12, based on the aforementioned examples, since two adjusting conditions are required during jacking operation, this scheme has two adjustment functions, wherein one realizes adjustment in a large range by moving the horizontal adjusting mechanism on the support plate 37, which is generally used when the inside of the jacking space changes; and the other is to adjust the positioning wheel 33 to move horizontally, mainly used for the uneven wall, to maintain the pressed state against the wall surface and bear force, thereby avoiding tilt. Such system has the function of simultaneous adjustments in a large range and in a small range, ensuring the stability of the system during jacking operation.

[0080]When in use, according to the range to be adjusted, the adjustment within a large range is performed first, wherein the installation plate 39 is moved to the position of the support plate 37, after reaching the correct position, four high streng...
