The invention discloses a construction method and a fixing structure of an ultra-high-rise floor inserting steel column. When a floor is constructed, an anchor bolt fixing frame and a layered positioning reinforcing steel mesh are embedded in a floor reinforcing steel structure, and an elongated anchor bolt is adopted as an anchor bolt and is fixedly provided on the anchor bolt fixing frame and the reinforcing steel mesh, and the upper end of the elongated anchor bolt protrudes above the bottom elevation of a steel column; an anchor plate is arranged at the bottom of a pedestal of the steel column, and concrete is poured to the bottom elevation of the anchor plate, and steel bars inserted into a column base are reserved, and the steel bars are arranged around the steel column. An insertingsteel column is installed, a pedestal anchor plate is fixed to the anchor bolt, and a reinforcing ring plate is welded on the steel column to complete the installation of the inserting steel column.The invention solves the construction problem of the ultra-high-rise floor inserting steel column by deepening the column base in the floor, adopting the anchor bolt fixing frame, the elongated pedestal anchor bolt, the anchor plate, the pedestal layered positioning reinforcing steel mesh and the layered pouring method.
Description
technical field [0001] The invention relates to the technical field of super high-rise building construction, in particular to a construction method and a fixing structure for an interposed steel column of a super high-rise floor. Background technique [0002] For super high-rise buildings in the form of concrete-filled steel tubes, the conventional steel structure columns are fixed with anchor bolts after the bottom slab is poured. Construction is simple. However, in order to solve the problem of structural stress, some engineering steel structure columns are embedded in the bottom plate. Due to the large size of super-high-rise column feet, complex excavation of column foundations, dense reinforcement on the bottom slab, precise positioning of column feet, long pouring period of large-volume concrete on the bottom slab, and vibration effects may cause positioning deviations of column feet, it is urgent to study proprietary technology to solve the problem .
