To prevent reduction of a grout joint area between precast members as much as possible by rationally reducing an edge portion that forms a joint space between the precast members.SOLUTION: There is provided a structure in which a first precast member 10 and a second precast member 20 are joined by a grout 3 filled in a joint space 2 between their end faces 12 and 22. Either one or both of the end faces 12 and 22 are precast with a pair of fringing projections 13, 23 contacting the end face of a mating precast member on the opposite sides of a peripheral edge portion that face each other in a length direction. There is no fringing projection contacting the end surface of the mating precast member over half or more of a length of the opposite sides of the peripheral edge portion that face each other in a transverse direction perpendicular to the length direction.SELECTED DRAWING: Figure 2
【課題】プレキャスト部材間に目地空間を形成するための縁取部を合理的に減少させて、プレキャスト部材間のグラウト接合面積が極力減少しないようにする。【解決手段】第１プレキャスト部材１０と第２プレキャスト部材２０とが、それらの端面１２，２２間の目地空間２に充填されたグラウト３により接合された構造において、前記両端面１２，２２のいずれか一方又は両方は、周縁部のうちの長さ方向に対峙する対辺部に、相手方プレキャスト部材の端面に当接する一対の縁取凸部１３，２３がプレキャストで形成され、該周縁部のうちの前記長さ方向に直交する横断方向に対峙する対辺部の長さの１／２以上に、相手方プレキャスト部材の端面に当接する縁取凸部が無い。【選択図】図２
