A jacket for bridge inspection is provided to increase durability by fixing closely to a pier and keeping strong against impact caused by floating matters on a river, to improve stability by binding strongly with a wire and a stiffening plate and preventing from inclining toward a handrail and to prevent the breakage of a bridge inspection system against various floating matters by controlling the height of a bridge inspection system easily according to circumferences. A jacket for bridge inspection comprises: many vertical frames(1) provided with one or more fixing ribs(11) having an anchor insertion hole(111) and adhered closely to the side of a pier(B) at regular intervals; stiffening frames(2) composed of a horizontal plate(21) adhered and supported closely to the top of the pier and a stiffening plate(22) erected on the top of the horizontal plate in one and provided with a wire fixing hole(23) to couple with a wire(5), and installed around a pier at regular intervals; a scaffold plate(3) coupled with the vertical frame by welding and extended outward to form a working space; and a safety handrail(4) fixed on the end of the scaffold plate vertically and reciprocated vertically by lifting up and down a reciprocating shaft according to the rotational direction of a fixing nut. |
