PREVENTIVE MAINTENANCE METHOD FOR STEEL BRIDGE
To provide a preventive maintenance method for a steel bridge that can significantly shorten a construction period, significantly reduce costs, and accurately determine whether peening has been performed appropriately.SOLUTION: A preventive maintenance method for a steel bridge includes: a blast step of performing blasting; a peening step of perform shot peening; a fluorescent paint applying step of applying a fluorescent paint before the peening step; and a coverage determination step of calculating coverage based on the residual fluorescent paint that produces fluorescence by irradiating a part to which the fluorescent paint is applied after the peening step.SELECTED DRAWING: Figure 1
【課題】工期を大幅に短縮でき、コストも大幅に縮小でき、さらに適切にピーニング処理が行われたかどうかを正確に判断できる鋼橋の予防保全工法を提供する。【解決手段】ブラスト処理を行うブラスト工程と、ショットピーニング処理を行うピーニング工程とを含み、ピーニング工程の前に蛍光塗料と塗布する蛍光塗料塗布工程と、ピーニング工程の後に蛍光塗料を塗布した部位に紫外線を照射して蛍光した残留蛍光塗料に基づいてカバレージを算出するカバレージ判定工程とを含む鋼橋の予防保全工法である。【選択図】図１
