UPWARD MOMENT-ENFORCEING UNIT AND BRIDGE STRUCTURE SETTLING THE SAME ON ITS LOWER STRUCTURE

摘要

The present invention relates to a bridge structure including a pile (1) for mounting an I-girder (10); the I-girder (10); a cap type socket (20) installed on the pile (1); and a unit (30) installed between the I-girder (10) and a support plate (23) of the cap type socket (20) to reduce negative moment in a support. According to the present invention, the bridge structure in which the unit is mounted on a lower structure can remarkably reduce the negative moment in the support in which the lower structure is connected to the girder so that a span between abutments and between piers is extended and the weight of a girder steel material can be reduced. Therefore, the bridge structure can obtain economic efficiency and reduce construction periods.
