摘要
After constructing a bridge using a double-composite steel box girder, it is manufactured with a split-placed lower concrete structure made to enable maintenance by corrosion of the double-composite steel box girder by rain lights (hereinafter referred to as penetration water). It is about the double composite steel box girder and its construction method. In the double-composite steel box girder, wherein the double-composite steel box girder is composed of a lower flange and both abdomens, and the lower concrete is integrally formed on the lower flange at the point portion, wherein the lower concrete is made of a steel box girder, 1 Primary lower concrete formed by the primary moisture absorption end plate; And a secondary lower concrete formed by a secondary moisture absorption end finish plate on the upper surface of the first lower concrete after mounting the steel box girder so that the first lower concrete is located at the point portion; including, the infiltration water finishes the first moisture absorption end. It is manufactured to prevent condensation by absorbing moisture by the plate and the secondary moisture absorbing end finish plate.
