UTILITY POLE, UTILITY POLE DETERIORATION TIME ESTIMATION DEVICE, AND UTILITY POLE DETERIORATION TIME ESTIMATION METHOD

To provide a utility pole capable of suppressing deterioration.SOLUTION: A utility pole 1 has a truncated cone shape or a cylindrical shape with a central axis extending in the vertical direction. The utility pole 1 includes a body part 11 and a plurality of reinforcing bars 12. The body part 11 constitutes at least a part of the utility pole 1 other than both end parts in the vertical direction, is made of concrete, and is hollow. The plurality of reinforcing bars 12 extend in the axial direction between an inner peripheral surface IS of the main body part 11 and an outer peripheral surface OS of the main body part 11. In the utility pole 1, for each of the plurality of reinforcing bars 12, a coating thickness ratio which is a ratio of an inner coating thickness T1 which is a distance between an inner peripheral surface IS of the body part 11 and the reinforcing bar 12 to an outer coating thickness T2 which is a distance between an outer peripheral surface OS of the body part 11 and the reinforcing bar 12 is 1.2 or less.SELECTED DRAWING: Figure 4 【課題】劣化を抑制することが可能な電柱を提供すること。【解決手段】電柱１は、中心軸が鉛直方向にて延在する円錐台状又は円柱状である。電柱１は、本体部１１と、複数の鉄筋１２と、を備える。本体部１１は、電柱１のうちの、鉛直方向における両端部以外の少なくとも一部を構成するとともに、コンクリートからなり且つ中空である。複数の鉄筋１２は、本体部１１の内周面ＩＳと本体部１１の外周面ＯＳとの間において軸方向にて延在する。電柱１は、複数の鉄筋１２のそれぞれに対して、本体部１１の内周面ＩＳと鉄筋１２との間の距離である内側被覆厚Ｔ１の、本体部１１の外周面ＯＳと鉄筋１２との間の距離である外側被覆厚Ｔ２に対する比である被覆厚比が１．２以下である。【選択図】図４
