ROD-SHAPED BODY AND CYLINDRICAL BODY
To provide a means capable of easily positioning and fixing a cylindrical body at a desired axial position of the rod-shaped body, improving the connectivity between rod-shaped bodies, and improving the pull-out strength of solidifying fluids such as concrete, mortar, and resin in the buried state.SOLUTION: The rod-shaped body has a reduced-diameter surface that exists in a predetermined region and is formed by gradually reducing the radius from the axis toward the central portion in the circumferential direction of the region, a rib that is arranged in a row in the axial direction and projects outward in the radial direction, and a concave radial surface that is recessed by alternating with the rib in the axial direction. The rib has a tip portion at a radial end portion, and a ridge line formed by the tip portion extends in a direction perpendicular to the axis and both ends thereof extend toward the reduced-diameter surface.SELECTED DRAWING: Figure 1
【課題】棒状体の所望の軸方向位置に容易に筒状体を位置決め固定可能で且つ棒状体同士の連結性が向上し且つコンクリートやモルタル、樹脂等の固化性流動体に対する埋設状態における引抜き強度を向上する手段を提供する。【解決手段】所定の領域に存して該領域の周方向中央部に向かって軸からの半径が漸次縮小して成る縮径面と、軸方向に列設されて径方向外向きに突出するリブと、軸方向に向って上記リブに交番して凹設される凹径面とを有し、上記リブは、径方向端部に先端部を有し、該先端部の成す稜線が軸直角方向に且つ両端が上記縮径面に向って延設される。【選択図】図１
