Non-welding type concrete-filled steel tube column using straight bolt connection slot and wave-shaped punching steel plate and method of constructing the same

A non-welding type concrete-filled steel tube (CFT) column using a straight bolt connection slot and a wave-shaped punching steel plate, the non-welding type CFT column comprising:

• external steel tubes including straight jointing portions in which inclined bolt grooves are formed to be vertically apart from each other and which are formed to extend from an end thereof to cover an overall extension length thereof;
• the straight bolt connection slot including straight plates connected to each other by a plurality of connection bolts and extending from the end of the external steel tubes vertically, the straight plates connected to each other by the connection bolts, and configured to integrate the external steel tubes by allowing each of the connection bolts to be inserted into each of the inclined bolt grooves in which the straight jointing portions of the external steel tubes are in contact with each other and communicate with each other;
• and
• concrete placed in the integrated external steel tubes and cured,
• wherein the straight bolt connection slot is a vertical plate form in which the straight plates are formed to face each other,
• wherein the straight plates are pre-assembled using the connection bolts, and each of the connection bolts of the pre-assembled straight bolt connection slot is inserted into each of the inclined bolt grooves of the straight jointing portions in contact with each other so that the connection bolts are disposed parallel to heating surfaces of the external steel tubes.
