HORIZONTAL RESTRAINING REINFORCEMENT MATERIAL FOR REINFORCED CONCRETE STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a horizontal restraining reinforcement material for a reinforced concrete structure, which can be easily constructed and which hardly deteriorates horizontal restraint performance of a cross section of concrete even in great deformation.;SOLUTION: The horizontal restraining reinforcement material 10 in the cross section of the reinforced concrete structure includes: a reinforcing bar 1 which is arranged in such a manner as to cross reinforcements 21 and 22 to be restrained in the cross section thereof; an anchoring plate 3 which is fixed to an end 2 of the reinforcing bar 1 in the direction of crossing the reinforcing bar 1 and wherein a holding hole 4 is provided in a part isolated from a fixed part 8 of the reinforcing bar 1 by at least a diameter D0 of the reinforcement 21 or 22; and a rod-shaped member 11 with one end 12 capable of being held in the holding hole 4. The rod-shaped member 11 is mounted into the holding hole 4 after the reinforcements 21 and 22 are restrained by the anchoring plate 3, and the reinforcements 21 and 22 are restrained by three elements, that is, the anchoring plate 3, the reinforcing bar 1 and the rod-shaped member 11. Preferably, the holding hole 4 serves as a screw hole, and at least one end 12 of the rod-shaped member 11 is provided with a thread which can be fitted into the screw hole thereof.;COPYRIGHT: (C)2005,JPO&NCIPI
