PERFORATED BEAM MADE OF REINFORCED CONCRETE
To provide a perforated beam made of reinforced concrete including a precast member, the perforated beam having an appropriate joint structure with a column or a girder.SOLUTION: A perforated beam 1 made of reinforced concrete includes a general portion 5 extending in a predetermined direction, and a pair of widened portions 6 that are connected to both ends of the general portion 5 in the predetermined direction and are wider than the general portion in the beam width direction so as to form a shoulder surface 7 facing inward in the predetermined direction. The perforated beam 1 is joined to a column 2 or a girder by a first tendon 4, one end of which is fixed to the shoulder surface 7. The first tendon 4 is an unbonded tendon. The widened portion 6 has a first opening that penetrates in the beam width direction at a position offset from the joint surface to a column 2 or main girder and the boundary surface with the general portion 5.SELECTED DRAWING: Figure 2
【課題】プレキャスト部材を含む鉄筋コンクリート造の有孔梁であって、柱又は大梁との適切な接合構造を有する有孔梁を提供する。【解決手段】鉄筋コンクリート造の有孔梁１は、所定方向に延在する一般部５、及び一般部５における所定方向の両端に連結し、所定方向の内方を向いた肩面７が形成されるように一般部よりも梁幅方向に拡幅された１対の拡幅部６を含む。有孔梁１は、一端部が肩面７に定着される第１緊張材４によって、柱２又は大梁に接合する。第１緊張材４は、アンボンド緊張材である。拡幅部６は、柱２又は大梁への接合面及び一般部５との境界面からずれた位置において、梁幅方向に貫通する第１開口部を有する。【選択図】図２
