PURPOSE: A bridge construction method using a girder in which a part in the longitudinal direction has a box-shaped cross-section is provided to secure enough bending strength against a load at the support of a bridge and enable efficient and economical construction of a girder bridge. CONSTITUTION: A bridge construction method using a girder in which a part in the longitudinal direction has a box-shaped cross-section is as follows. Two or more steel plate girders(100) are parallely installed at an interval in the traverse direction. A traverse closing member(200) is installed between two steel plate girders so that the adjacent girders form a box-shaped cross-section. |
