Support structure of internal-climbing tower crane

Abstract

The invention provides a support structure of an internal-climbing tower crane, which is used for supporting an internal-climbing tower crane body and arranged on the outer side of a core tube shear wall. The support structure of the internal-climbing tower crane comprises two steel columns, a steel beam, two support beams and an internal-climbing frame. Compared with a support structure of an external-hanging internal-climbing tower crane in the prior art, the support structure of the internal-climbing tower crane is provided with the steel columns and the steel beam, reduces quantity of embedded parts required by each support, enables the support beams to obtain four-point support, enables the internal-climbing frame arranged on the two support beams to be firm, and improves safety of the internal-climbing tower crane in climbing or use.

Description

technical field [0001] The invention relates to construction equipment for high-rise buildings and structures with a frame core tube structure system, in particular to a support structure for an internal climbing tower crane. Background technique [0002] With the rapid development of super high-rise buildings and structures, internal climbing tower cranes, as the most effective vertical transportation machinery in construction, are widely used. As a force transmission device connecting the tower crane with buildings or structures, the supporting structure of the inner climbing tower crane plays a vital role in reducing the free height of the inner climbing tower crane and maintaining the stability of the inner climbing tower crane effect. [0003] At present, the internal climbing tower cranes used in the construction of high-rise and super high-rise buildings are either placed in the vertical shaft of the core tube, or hung outside the core tube shear wall. Most super hi...

AI Technical Summary

Problems solved by technology

[0004] When the fuselage of the internal climbing tower crane in the prior art is hung on the outside of the shear wall of the cylinder, there is a problem of high cost and high safety control requirements

like figure 1 and figure 2 As shown, when the fuselage 1 of the tower crane adopts the external hanging and internal climbing method, each wall-attached support structure is composed of a support beam 5, a vertical diagonal strut 15, a horizontal diagonal strut 16 and an internal climbing frame 6. When the aforementioned support beam 5, vertical diagonal braces 15 and horizontal diagonal braces 16 are attached to the core tube shear wall 2, it is necessary to place steel embedded parts 8 before the concrete pouring of the shear wall, and place the support beams 5, vertical braces Diagonal braces 15 and horizontal braces 16 are welded to embedded parts 8. The inner climbing frame 6 is installed on the support beam 5. The number of embedded parts 8 required for each wall support is 4-6 pieces. The support structure of this internal climbing tower crane requires a large number of embedded parts 8, high positioning accuracy requirements, and a large amount of high-altitude on-site welding operations, which increases the cost and the difficulty of construction safety supervision.
