<P>PROBLEM TO BE SOLVED: To provide a girder-to-girder connection device which is mounted between bridge girders at supporting locations of a viaduct etc., enhances the continuity between the girders, reduces vibration and noise, and reduces damage of the girders caused by an earthquake. <P>SOLUTION: The girder to girder connection device includes: a joint plate 20 which is mounted on the girder end of one bridge girder and is extended to the girder end of the other bridge girder, the bridge girders being adjacently supported on supporting members; a displacement limiting piece 30 which is fixed to the girder end of the other bridge girder and inhibit fluctuation in the vertical direction of the joint plate 20 by the function of tapered surfaces 25, the tapered surfaces 25 are formed to be fittable in the upper and lower edge of the displacement limiting piece 30 and the inner peripheral surface of the opening in the joint plate 20; and a sliding member 35 interposed between the joint plate 20 and the displacement limiting piece 30, and allows relative displacement between the joint plate 20 and the displacement limiting piece 30 in a bridge axial direction. In the girder to girder connection device, the restraint of the displacement limiting piece 30 inhibits relative displacement between the bridge girders in the vertical direction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
