The present invention relates to a superstructure comprising: a coping (120, 220) installed on the upper end of a bridge pier; and a girder (130, 230) mounted to the coping, wherein the side surfaces of the coping and the side surfaces of the end portion of the girder are formed into inclined (or vertical) surfaces and come into close contact with one another; a shear key protrudes from one inclined (or vertical) surface of the pair of inclined (or vertical) surfaces; and a shear key groove, into which the shear key can be inserted, is formed on the other of the pair of inclined (or vertical) surface. Due to this configuration, construction costs can be reduced, structural efficiency exists, mounting of girders is facilitated, girders may be coupled to copings without the need for on-site pouring of mortar, and the resistance to shear, which may occur during the operation of a bridge, is increased. |
