STEP PREVENTION MEMBER AND BRIDGE
To provide a step prevention member with a desired mechanical strength, being light weight, and easy to install, and a bridge having the step prevention member.SOLUTION: A step prevention member 10 installed on an upper part 131 of a bridge pier 13 of a bridge 1 in close proximity of a support part 15 that supports a bridge girder 14 and suppresses the downward displacement of the bridge girder 14 preventing the formation of a step by supporting the bridge girder 14 with the support part 15 or instead of the support part 15 even when the states in which the bridge girder 14 cannot be sufficiently supported by the support part 15, includes a body being a fiber-reinforced resin composite having a columnar or tubular shape and being composed of resin and a plurality of fibers having a tensile strength of 2000 MPa or more.SELECTED DRAWING: Figure 1
【課題】所望の機械的強度を有するとともに、軽量であって簡便に設置することが可能な段差防止材およびこの段差防止材を有する橋梁を提供する。【解決手段】段差防止材１０は、橋梁１の橋脚１３の上部１３１に、橋桁１４を支持する支承部１５の近い位置に設けられ、支承部１５による橋桁１４の支持が十分に行えなくなる状況が生じた場合であっても、支承部１５とともに、または支承部１５に代わって橋桁１４を支持することにより、橋桁１４が下方変位することを抑制して段差が生じるのを防止するものであって、樹脂と、引張強さが２０００ＭＰａ以上である複数本の繊維とで構成され、柱状または筒状の形状を有する繊維強化樹脂複合体である本体部を備える。【選択図】図１
