MANUFACTURING METHOD OF RAIL COVERING STRUCTURE
To provide a manufacturing method of a rail covering structure which is excellent in the effect of preventing rail corrosion and is easy to operate.SOLUTION: A manufacturing method of a rail covering structure 30, which includes a rail 10 and a covering layer 20 that covers a portion of the rail 10, in which the covering layer 20 includes a cured product of a fiber-reinforced prepreg that has a reinforcing member and curable resin, includes: an adhesive application process to apply an adhesive to a work surface of the rail 10; an attachment process to attach a prepreg sheet including the fiber-reinforced prepreg onto the adhesive before the adhesive applied to the construction surface cures; an adhesive curing process in which the adhesive cures after the attachment process; and a covering layer curing process in which the curable resin cures after the attachment process to form the covering layer 20.SELECTED DRAWING: Figure 1
【課題】レールの腐食防止効果に優れ、かつ作業が簡便である、レールの被覆構造体の製造方法を提供する。【解決手段】レール１０と、前記レール１０の一部を覆う被覆層２０とを有し、前記被覆層２０は補強部材と硬化性樹脂とを有する繊維強化プリプレグの硬化物を含む、レールの被覆構造体３０の製造方法であって、前記レール１０の施工面に接着剤を塗布する接着剤塗布工程と、前記施工面に塗布した前記接着剤が硬化する前に、前記接着剤上に前記繊維強化プリプレグを含むプリプレグシートを貼り付ける貼付工程と、前記貼付工程の後に前記接着剤を硬化する、接着剤硬化工程と、前記貼付工程の後に前記硬化性樹脂を硬化して前記被覆層２０とする被覆層硬化工程と、を有することよりなる。【選択図】図１
