GIRDER USING UPPER CLOSING PLATE AND THE CONSTRUCTION METHOD THEREWITH

摘要

The present invention relates to a girder using an upper steel composite cover plate and a construction method thereof. The present invention has an effect of more economically constructing a girder by reinforcing rigidity and buckling when both girders are connected to each other in a transverse direction. The upper cover plate comprises: a cover plate formed in the upper surface of a girder; a protruding block having a through hole formed in the upper surface of the cover plate; and a steel material inserted into the connected through hole. Therefore, the girder useful for a support part and a curved bridge can be provided.
