REBAR STRUCTURE AND REINFORCED CONCRETE STRUCTURE
PROBLEM TO BE SOLVED: To provide a rebar structure in which a through-hole for equipment piping can easily be constructed in the vicinity of a column.SOLUTION: A main reinforcement 21 for a beam is constituted by including a normal rebar 212 with the yield point or 0.2% proof stress defined in JISG3112 and a high-strength bar 211 with the yield point or 0.2% proof stress larger than that of the normal rebar 212. The high-strength bar 211 is disposed in a beam-column connection 200, and a first high strength region 201 and a second high strength region 202 along the beam length direction from the beam-column connection 200, respectively. The normal rebar 212 is disposed in a normal rebar region 210 positioned in the side opposite to the beam-column connection 200 across the first high strength region 201. An opening region 50 arranged with a through-hole 5 for equipment piping is contained in the first high strength region 201 and the second high strength region 202.
【課題】設備配管用貫通孔を柱の近傍において容易に施工することができる鉄筋構造を提供する。【解決手段】降伏点又は０.２％耐力がＪＩＳＧ３１１２で規定される普通鉄筋２１２と、普通鉄筋２１２よりも降伏点又は０.２％耐力が大きい高強度鉄筋２１１とを備えて梁用の主筋２１を構成し、高強度鉄筋２１１を、柱梁接合部２００、柱梁接合部２００からそれぞれ梁長さ方向に沿った第一高強度領域２０１及び第二高強度領域２０２に配置し、普通鉄筋２１２を、第一高強度領域２０１を挟んで柱梁接合部２００とは反対側に位置する普通鉄筋領域２１０に配置した。第一高強度領域２０１及び第二高強度領域２０２に、設備配管用貫通孔５が配置される開孔領域５０が含まれている。【選択図】図２
