PRECAST MEMBER
To obtain a large-sized precast member that has high strength and can be easily manufactured.SOLUTION: This precast member 1 is mainly composed of ultra-high performance fiber reinforced concrete (UFC), and includes an outer wall portion 10 having a substantially cylindrical outer surface and a substantially cylindrical inner surface concentric with the outer surface. The outer wall portion 10 is a thin portion 10A that is uniformly thin in the lower region R1 in the z direction, while the outer wall portion 10 is a thick portion 10B in the upper region R2 that is thicker toward the central axis C1 side. In addition, in the lower region R1, ribs 11A to 11F whose inner surfaces locally protrude toward the central axis C1 along the vertical direction are formed at equal intervals in the circumferential direction.SELECTED DRAWING: Figure 1
【課題】高い強度をもち容易に製造が可能な大型のプレキャスト部材を得る。【解決手段】このプレキャスト部材１は、超高性能繊維補強コンクリート（ＵＦＣ）を主成分として構成され、略円筒形状の外面と、この外面と同心となる略円筒形状の内面を有する外壁部１０を具備する。外壁部１０は、ｚ方向における下側の領域Ｒ１では一様に薄く形成された薄肉部１０Ａとなっているが、上側の領域Ｒ２では、これよりも中心軸Ｃ１側に向けて厚くされた厚肉部１０Ｂとなっている。これに加え、下側の領域Ｒ１では、鉛直方向に沿って内面が中心軸Ｃ１側に向かって局所的に突出したリブ１１Ａ～１１Ｆが、円周方向において等間隔で形成されている。【選択図】図１
