PROBLEM TO BE SOLVED: To provide a reinforced concrete column that secures safety even when heated by a fire disaster and the like. ! SOLUTION: A reinforced concrete column 1 includes a concrete hardened body 2, and main reinforcements 3, 3... that are arranged at corner parts of the concrete hardened body 2, respectively. A longitudinal central part of the main reinforcement 3 is made of a high-strength bar 3a. Other parts (both ends) of the main reinforcement 3 are made of normal reinforcements 3b and 3b that are coupled to the high-strength bar 3a. The high-strength bar 3a and the normal reinforcements 3b and 3b are joined together by friction welding. ! COPYRIGHT: (C)2015,JPO&INPIT |
