CONNECTING STRUCTURE USING OF CONCRETE CAGE AND METHOD STRENGTHING FLEXURAL STRENGTH OF STEEL COLUMN AND STEEL PIPE JOINT OF THE SAME

摘要

According to an embodiment, the present invention provides a concrete cage which is formed to surround a connection unit connecting the upper end of a steel pile and the lower end of a steel column and has concrete poured on the inside to reinforce the bending strength of the connection unit in the lateral direction. The present invention installs the concrete cage surrounding the connection unit and pours concrete in the cage to integrate the connection unit and the concrete cage and increase a cross-sectional area in the lateral direction, thereby reinforcing the bending strength of the connection unit in the lateral direction.
