Embodiment 1

[0054] A synchronous lifting device for steel platforms and tower cranes alternately supported by steel columns and tube frames, including steel platforms, tower cranes, hoisting steel columns 1 and a lifting power system; 201. The overall lifting beam 6 and the horizontal support beam 7, the steel platform top beam, the cylinder frame support, the overall lifting beam and the horizontal support beam are arranged sequentially from top to bottom; the steel platform top beam 2 is provided with a horizontal limit guide Wheel 8, the guide wheel can selectively resist the tower crane, the tower crane includes a tower crane standard section, the tower crane is connected to the integral lifting beam 6, and the lower part of the tower crane is fixedly connected to the horizontal support beam 7; The lifting power system is used to provide lifting power to move the steel platform along the lifting steel column.

[0055] Specifically, by connecting the tower crane with the steel platform...

Embodiment 2

[0075] A synchronous lifting method using the above synchronous lifting device, its implementation process can be decomposed into: initial state, lifting process, lifting in place, lifting the lifting steel column back, and lifting completed.

[0076] Specifically, the above synchronous promotion method specifically includes the following steps:

[0077] Step 1: In the initial state, complete the preparatory work before lifting; preferably, confirm that the tower crane is in a non-working state and check whether each component has the lifting conditions, ensure that the hydraulic telescopic guide roller 5 is tightly pressed against the core tube structure, and the steel column is lifted below, Do a good job of fixing the lifting steel column and the shear wall, connect the lifting steel column and the wall, and tighten the horizontal limit guide wheel of the top beam of the steel platform with the standard section of the tower body of the tower crane to limit the horizontal dis...

Abstract

The invention relates to a synchronous hoisting device for a steel column casing rack alternate support type steel platform and a tower crane and a hoisting method of the synchronous hoisting device.The hoisting device comprises the steel platform, the tower crane, hoisting steel columns (1) and a hoisting power system. The steel platform comprises a steel platform top beam (2), casing rack supports (201), an integral hoisting beam (6) and a horizontal support beam (7). The steel platform top beam, the casing rack supports, the integral hoisting beam and the horizontal support beam are arranged in sequence from top to bottom. The steel platform top beam (2) is provided with horizontal limiting guiding wheels (8). The guiding wheels abut against the tower crane in a selectable manner. Thetower crane is connected with the integral hoisting beam (6). The lower portion of the tower crane is fixedly connected with the horizontal support beam (7). The hoisting power system is used for providing hoisting power so that the steel platform can move along the hoisting steel columns. By means of the synchronous hoisting device, integral hoisting of the tower crane and the steel platform is achieved, and the problem that the tower crane interferers with the steel platform easily in the traditional construction process is solved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a synchronous lifting device and a lifting method for a steel platform and a tower crane that are alternately supported by a steel column frame. Background technique [0002] At present, the alternately supported steel platform of steel columns and tube frames is often used in super high-rise structures above 250m, which has the advantages of strong sealing, convenient lifting, fast construction speed and less steel consumption. In the construction of super high-rise structures, large-scale jib tower cranes are mainly used for hoisting and vertical transportation of large rigid components. In the construction process of super high-rise buildings, the large-scale tower crane responsible for vertical transportation and the integrated platform used for core tube construction belong to two different systems. At present, the steel platform and the tower crane are alterna...
