Design Technology of Walking Track for Walking Tower Crane Under Complex Elevation
The large-scale domestic conference and exhibition center mostly adopts the combination form of underground concrete structure and above-ground steel structure,with walking tower crane as the main construction machinery of above-ground steel structure.Aiming at the difficulties of complex elevation for basement concrete roof falling plate and roof strength not meeting the station position of large equipment,a set of track beam support system suitable for different elevations of basement roof is successfully developed by designing track,track beam,round tube support and cap foundation as the basis of walking tower crane,which solves the problem that there is no support point of track beam in falling plate area,and forms the design technology of track and track beam for tower crane to move horizontally.Compared with the traditional attached self-elevating tower crane,the difficulty of changing the layout of tower crane in different construction stages of the project is solved by this technology.
