PURPOSE: An upper structure of a bridge is provided to easily arrange a girder by having an inclined contacting plane of a coping and the girder, to join the coping and girder without placing cast-in-place mortar tasking by installing a sheer key on the inclined plane, and to enhance the resistance with respect to the shear created while using a bridge. CONSTITUTION: An upper structure of a bridge comprises a coping(120) and a girder(130). The coping is installed in the upper part of a pier(110). The girders are arranged in both sides of a width direction of the coping along a longitudinal direction of a bridge. A side of the coping and a side of an end part of the girder are formed to be inclined, thereby being closely adhered. A shear key is projected in one inclined plane between a pair of the inclined planes. A shear key groove where the shear key is inserted is formed in the other inclined plane. |
