PURPOSE: A dust removal device is provided to have out-of-plane strength by connecting a restraining plate to both sides of a steel plate, thereby preventing out-of-plane deformation of the steel plate. CONSTITUTION: A dust removal device (1a) for a structure comprises an upper and a lower part end plate (11,12), vertical plates (31,32), steel plates (20), and a restraining plate (41). The upper and the lower part end plate are combined with a beam of a structure. The steel plate is provided in among the upper part end plate, the lower part end plate, and multiple vertical plates. The restraining plate is mounted on the side of the steel plate; restrains out-of-plane deformation; and comprises a first restraining plate which is mounted on one side of the steel plate and a second restraining plate which is mounted on the rear side. The restraining forms a through hole through which a fastening member (70) passes for combining the first restraining plate with the second restraining plate. |
