Telescopic climbing beam device and using method thereof

Abstract

The invention provides a telescopic climbing beam device and a using method thereof, and relate to the technical field of super high-rise building construction. The problems that because an existing tower crane climbing beam needs to be welded and lengthened to deal with the interior wall of a core cylinder, the eccentric bending moment of a shear wall is large is solved. The telescopic climbing beam device comprises a pair of climbing main beams, four telescopic beams and a plurality of arc-shaped groove brackets, wherein the pair of climbing main beams are parallel and arranged at intervals,the four telescopic beams sleeve the two ends of the climbing main beams respectively, and the plurality of arc-shaped groove brackets are arranged in the climbing direction of a tower crane and arefixedly connected to the shear wall at the two sides; one ends of the telescopic beams are connected with bolts of the climbing main beams, the other ends of the telescopic beams are connected with pin shafts, and the telescopic beams are detachably connected with the arc groove brackets. The using method comprises the following steps that an embedded part is embedded in the shear wall, the arc groove brackets and the embedded part are welded and fixed; and the telescopic lengths of the telescopic beams are adjusted, so that limiting bolts in the same plane of the climbing main beams and the telescopic beams are corresponding to each other and are tightened and fixed, and are lifted to the upper parts of the arc-shaped groove brackets and placed in the arc-shaped grooves, the pin shafts ofthe telescopic beams are clamped in the arc-shaped grooves of the arc-shaped groove brackets, and clamping buckles on the upper parts of the brackets of the arc-shaped grooves are locked and fixed.

Description

technical field [0001] The invention relates to the technical field of super high-rise building construction, in particular to a telescopic climbing beam device used for an inner-climbing boom tower crane of a super high-rise building and a use method thereof. Background technique [0002] With the rapid rise of super high-rise buildings, large-scale luffing jib tower cranes have been widely used as the main vertical transportation equipment during the construction of super high-rise buildings. [0003] At present, large-scale luffing jib tower cranes mainly adopt two types of support methods: external suspension and internal support. Among them, the support structure of the luffing jib tower crane adopting the internal support method is as follows: pre-set embedded parts in the core tube shear wall, then weld the corbels to the embedded parts, then place the climbing beam on the corbels and Welding on three sides is complicated and difficult to operate; moreover, when the ...

AI Technical Summary

Problems solved by technology

[0004] When the climbing beam of the existing internal support structure is to shrink the inner wall of the core tube, the climbing beam needs to be welded and lengthened. Not only the construction process is complicated, the high-altitude operation time is long and the construction risk is high, but also the corbel and surrounding shear walls are damaged. The problem of increased eccentric bending moment
