PROBLEM TO BE SOLVED: To provide a louver system on the rear surface of an elevated road and a repair method enabling a louver to be attached, detached, replaced and repaired from the ground side below a beam of the elevated road. SOLUTION: A boxlike body with its lower face opened is formed of a rear surface plate having a rectangular plane and side wall plates provided on its four sides. A plurality of louvers are arranged substantially in parallel on the lower face of the boxlike body. The plurality of louvers are constituted as a louver unit connected with a holding member in which its upper face is arranged in at least two orthogonal directions. The holding member is attached to the side wall plate arranged in parallel with the holding member in the boxlike body. The rear surface plate is suspended and supported on a substrate member on the rear surface of the elevated road by a suspension means. COPYRIGHT: (C)2004,JPO
