<p><P>PROBLEM TO BE SOLVED: To easily fix oblique reinforcing members. <P>SOLUTION: A reinforcing structure around a through-hole of a concrete beam includes the main reinforcement 6, stirrups 7, the through-hole 2 in the width direction of the beam, and an annular reinforcing member 10 surrounding the through-hole 2. The oblique reinforcing members 20 are locked to the main reinforcement 6. The oblique reinforcing member 20 includes a locking part 21 to the main reinforcement 6, and shear reinforcing parts 22 extended from the locking part 21 respectively to both sides in a beam axis direction of the through-hole 2 to gradually approach the center in the height direction of the beam. Since the shear reinforcing parts 22 having a function of coping with shear cracks formed around the through-hole 2 extend to both sides of the beam axis direction from the locking part 21, the oblique reinforcing member 20 is well-balanced on both sides of the locking part 21. Thus, once the locking part 21 is locked to the main reinforcements 6, the attitude of the oblique reinforcing member 20 hardly changes after the locking, facilitating fixing of the oblique reinforcing member 20. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
