The present invention relates to a mounting member used in a concrete-filled steel pipe pillar, a structure and a method for installing a concrete-filled steel pipe pillar and a bracket using the same, and a structure and a method for constructing an underground structure comprising the same. A concrete-filled steel pipe pillar which is a permanent pillar is installed in the ground where a retaining wall is formed, and a bracket is detachably fixed on the concrete-filled steel pipe pillar by a fixing nut mounted on a mounting member. Then a work process for supporting a steel beam can be shortened, and the bracket is separated from the concrete-filled steel pipe pillar when the fixing nut is separated from the mounting member to shorten a work process for installing and separating the bracket to shorten construction time to improve economic efficiency. |
