PROBLEM TO BE SOLVED: To settle a joint part of reinforcing bars in a reinforcing concrete surely while connecting them in the concrete.;SOLUTION: A beam main reinforcement 1a projecting from an end face of a PCa beam 1 is inserted into a beam main reinforcement hole 3b of a PCa joint panel member 3 from each of both sides. The beam main reinforcement hole 3b includes a sheath pipe 11 where the beam main reinforcement 1a is fixed with a grout. A knot part 11a is provided on the outer periphery of the sheath pipe 11. The beam main reinforcement 1a is settled in the concrete by a bearing force applied to the knot part 11a. A special shape part 11 may be provided on the outer periphery of the sheath pipe 11 so that an adhesive force is applied to the special shape part 11b. This is applicable for connecting reinforcing bars as well as for connecting the beam main reinforcements.;COPYRIGHT: (C)2005,JPO&NCIPI
