BEAM FLOOR JUNCTION STRUCTURE
To provide a beam floor junction structure for a wooden beam and a floor slab made of cast-in-place concrete, which can be easily formed and can secure stable shear capacity in a stable state.SOLUTION: A beam floor junction structure 10 for integrally joining a wooden beam 11 with a concrete floor slab 12 formed by installing cast-in-place concrete on a top surface of the wooden beam includes shear force transmission means for transmission between the wooden beam and the concrete floor slab. The shear force transmission means is formed so as to include: a shear cotter surface part 15 that is formed on a top surface of the wooden beam and has a saw blade-like cross-sectional shape in which a plurality of protrusions 15a having a triangular cross-sectional shape succeeds along an axial direction of the wooden beam; and an engagement lower surface part having a plurality of engagement protrusions that is formed on a lower surface part of the concrete floor slab by installed concrete having solidified after entering recesses 15b among the protrusions having the triangular cross-sectional shape of the shear cotter surface part and individually engages with the plurality of protrusions of the shear cotter surface part.SELECTED DRAWING: Figure 1
【課題】簡易に形成できると共に、安定した状態でせん断耐力を確保することのできる木製梁と現場打ちコンクリートによる床スラブとの梁床接合構造を提供する。【解決手段】木製梁１１と、木製梁の上面に現場打ちコンクリートを打設して形成されたコンクリート製床スラブ１２と、を一体として接合するための梁床接合構造１０であって、木製梁とコンクリート製床スラブとの部材間で伝達させるせん断力伝達手段を有しており、せん断力伝達手段は、木製梁の上面に形成された、複数の三角断面形状の凸部１５ａが木製梁の軸方向に沿って連続するノコギリ刃状の断面形状を備えるシアコッター面部１５と、シアコッター面部の三角断面形状の凸部間の凹部１５ｂに、打設されたコンクリートが入り込んで固化することでコンクリート製床スラブの下面部に形成された、シアコッター面部の複数の凸部と各々噛合する複数の噛合凸部を有する噛合下面部とを含んで形成されている。【選択図】図１
