BEAM MEMBER AND JOINT STRUCTURE BETWEEN BEAM MEMBER AND VERTICAL MEMBER
To provide a precast concrete beam member that can increase the shear strength of the member and its joint part with other members without increasing the section size.SOLUTION: A precast concrete beam member 20 is provided with a beam body 21 formed of steel fiber reinforced concrete, beam main reinforcement 22 and shear reinforcement 23 arranged inside the beam body 21, and convex parts 24 provided on both end faces of the beam body 21. The convex part 24 is formed of steel fiber-reinforced concrete. By joining the beam member 20 and a column member 10 in a shear key composed of the convex part 24 of the beam member 20 and a concave part 11 of the column member 10, the shear strength of the joint part between the beam member 20 and the column member 10 and the deformation performance of the beam member 20 can be increased without increasing the cross-sectional size of the beam member, improving the concrete strength of the beam member and increasing the amount of reinforcement for shear reinforcement.SELECTED DRAWING: Figure 1
【課題】断面サイズを大きくすることなく、部材および他部材との接合部のせん断強度を増大できる、プレキャストコンクリート造の梁部材を提供すること。【解決手段】プレキャストコンクリート造の梁部材２０は、鋼繊維補強コンクリートで形成された梁本体２１と、梁本体２１の内部に配筋された梁主筋２２およびせん断補強筋２３と、梁本体２１の両端面に設けられた凸部２４と、を備える。凸部２４は、鋼繊維補強コンクリートで形成される。本発明によれば、梁部材２０の凸部２４と柱部材１０の凹部１１とからなるシヤーキーで、梁部材２０と柱部材１０とが接合することにより、梁部材の断面サイズを大きくしたり、梁部材のコンクリート強度を向上させたり、せん断補強筋の鉄筋量を増大させたりすることなく、梁部材２０と柱部材１０との接合部分のせん断強度および梁部材２０の変形性能を増大できる。【選択図】図１
