Technical Field
With the development of society, super high-rise buildings flash like spring bamboo shoots after rain, and designers gradually start to transition from simple height requirements on the buildings to additional cradles on the integral modeling of the buildings, especially the novelty and the variability of the appearance of the buildings, which brings great difficulty to the protection of the outer facade during super high-rise construction. The traditional steel pipe overhanging scaffold and the traditional attached lifting scaffold can not meet the construction requirements of modern super high-rise buildings with various outer facades, and the construction of the building serving as a landmark type building can adopt curved surface appearance design more. With respect to the prior art, intelligent attaching lifting scaffolds for curved super high-rise buildings are not provided with complete equipment and methods at present.
The traditional steel pipe overhanging scaffold cannot be erected along inclined planes and curved surfaces, so that the traditional steel pipe overhanging scaffold has the defects of more dangerous factors and low construction speed, occupies a large number of tower crane shifts and working surfaces, and severely restricts the smooth progress of engineering construction.
The patent 201610775413.6 discloses a multi-time variable cross-section lifting device and a construction method for an ultra-high-rise all-steel climbing outer frame, and adopts the multi-time variable cross-section lifting construction method for the ultra-high-rise all-steel climbing outer frame, wherein the main flow comprises the steps of entering a conventional lifting cycle to a variable cross-section layer, embedding clamping grooves, installing temporary attachment supporting points, vertically climbing, hydraulic sliding, replacing the supporting points one by one, removing the temporary supporting points, completing the section changing lifting, and entering the conventional lifting cycle. Including climbing the frame guide rail, climb frame guide holder and all steel and climb the frame, climb the frame guide holder and install on building structure, climb and set up on the frame guide holder and climb the frame guide rail, all steel climbs the frame and adhere to on climbing the frame guide rail, still include horizontal guide rail, horizontal spout and interim support frame, the tip of horizontal guide rail passes through the pre-buried snap ring of U type to be fixed on the floor, the middle part of horizontal guide rail sets up the hole, the screw rod passes the hole and passes through the nut to be fixed on dismantling the snap ring, can dismantle the snap ring to be fixed on the floor, horizontal guide rail stretches into in the horizontal spout, the bottom surface at interim support frame is fixed to the horizontal spout, the upper end of interim support frame sets up the screw hole of being connected with climbing the frame guide holder.
The outer frame climbing and angle adjustment are both carried out by means of sliding adjustment of the climbing beam, when the outer frame is required to be adjusted according to the change of the section in a specific construction process, the angle of the outer frame to be adjusted cannot be accurately achieved by means of the cooperation of the horizontal guide rail and the horizontal sliding groove, meanwhile, the horizontal guide rail moves in the sliding groove to realize synchronous operation of the outer frame, and if the outer frame is likely to be stressed unevenly or even distorted due to improper operation, accidents are likely to occur seriously.
Whether there is an intelligent lifting scaffold adapting to the curved surface super high-rise building, climbing and angle adjustment of the intelligent lifting scaffold can be divided into two different systems, and the two systems can mutually support and jointly bear stable stress.

The second climbing beam one end is connected with the channel-section steel seat, is provided with the spread groove in the middle of the channel-section steel seat, and the channel-section steel seat can be articulated behind the corresponding position welded connecting plate in the pole setting through inserting the spread groove, under hydraulic cylinder's drive, realizes climbing frame angle's adjustment through hydraulic stem's flexible.
The climbing frame body covers four floors. The height of the climbing frame is set according to the conventional four-layer height, so that the stability and the stress uniformity of the structure of the frame body are facilitated, the situation that the frame body is required to be manufactured to rise due to excessive layers can be avoided, and the higher cost performance is guaranteed.
The first climbing beam and the second climbing beam are correspondingly arranged on each layer, namely, the first climbing beam and the second climbing beam which are positioned at the same position of different layers are respectively arranged on the same vertical line. The climbing device can climb along the climbing track of the same vertical line, and meanwhile, the stress uniformity in the angle adjusting process is met.
