ABSTRACT:
A concrete filled tube column includes: an outer tube connected to beams of the structure, the outer tube consisting of a plurality of tube pieces coaxially disposed in series; a concrete core disposed within the outer tube; an inner flange peripherally mounted on the inner face of each tube piece; and a concrete layer peripherally disposed on the inner face of each tube piece. The concrete layer includes a tubular portion positioned under the inner flange and in direct contact with the entire lower side of the inner flange. The tubular portion has an inner peripheral face tapering upward so that the transverse inner size at the lower end of the tubular portion is equal to the transverse inner size of each tube piece. In constructing the column, a plurality of the precast structural tubes, each including: the tube piece; the inner flange; and the concrete layer, are prepared. Then, one of the precast tubes is erected. Concrete is placed within the erected precast tube to form a concrete core. The beams of the structure are connected to the erected precast structural tube. Another precast tube is coaxially connected to the upper end of the erected precast tube, whereby said another precast tube is erected on the lower adjoining structural tube. Thereafter, the steps from the concrete-placing step to the tube-connecting step are repeated a plurality of times.
