COLUMN BEAM FRAME STRUCTURE, CONSTRUCTION METHOD OF COLUMN BEAM FRAME STRUCTURE AND PCa MEMBER

PROBLEM TO BE SOLVED: To provide a column beam frame structure, construction method of the column beam frame structure, and PCa member, which enable easy manufacturing of the PCa member, labor saving for construction of a frame mold and grout, and construction in an ultrashort work period.SOLUTION: A column beam frame structure comprises: a first column PCa member 12, which has a steel bar 18 projecting from a top face, an insertion hole 20 extending from an undersurface to inside, and a steel bar 22 projecting from an upper side face; a second column PCa member 14, which has an insertion hole 24 extending from the top face to inside, a steel bar 26 projecting from the undersurface, and a steel bar 28 projecting from a lower side face; and a beam PCa member 16, which has an insertion hole 30 extending from one side face to inside and a steel bar 32 projecting from the other side face. The steel bar 22 of the first column PCa member 12 is inserted into the insertion hole 30 of the beam PCa member 16, the steel bar 32 of the beam PCa member 16 and the steel bar 28 of the second column PCa member 14 are connected through a joint 36, and a space between the beam PCa member 16 and the second column PCa member 14 is connected by a cast-in-place concrete.SELECTED DRAWING: Figure 1 【課題】ＰＣａ部材の製作が容易で、型枠やグラウト工事の省力化が図れ、超短工期施工が可能な柱梁架構構造、柱梁架構構造の構築方法およびＰＣａ部材を提供する。【解決手段】上面から突出する鉄筋１８と、下面から内部に延びる挿入孔２０と、上部の側面から突出する鉄筋２２とを有した第１柱ＰＣａ部材１２と、上面から内部に延びる挿入孔２４と、下面から突出する鉄筋２６と、下部の側面から突出する鉄筋２８とを有した第２柱ＰＣａ部材１４と、一方の側面から内部に延びる挿入孔３０と、他方の側面から突出する鉄筋３２とを有した梁ＰＣａ部材１６とを備え、梁ＰＣａ部材１６の挿入孔３０に第１柱ＰＣａ部材１２の鉄筋２２を挿入し、梁ＰＣａ部材１６の鉄筋３２と第２柱ＰＣａ部材１４の鉄筋２８とを継手３６で接合し、梁ＰＣａ部材１６と第２柱ＰＣａ部材１４との間を現場打ちコンクリートで接合した。【選択図】図１
