<p>The present invention relates to a bridge construction method using an end part vertical tendon passing through a PSC girder holding step and the continuous step and the slab construction step to more effectively use sectional strength of a PSC girder. The bridge construction method comprises the steps of: enabling the PSC girder of which both end parts have a vertical tension hole to be held to be supported by an end part support installed on an upper surface of a lower structure of a bridge and enabling the end part vertical tendon to be inserted into the vertical tension hole to be withdrawn upward; mounting the end part vertical tendon to the upper surface of both end parts of the PSC girder to introduce vertical tension (P1) after the end part vertical tendon is tensioned; performing continuous construction of the PSC girder with the slab construction together; cutting the end part vertical tendon using a lower space of the bottom surface of the PSC girder; tensioning the secondary PSC tendon of the PSC girder which are adjacent to a continuous point and mounting the secondary PSC tendon of the PSC girder to each end part reinforcement block bypassing each continuous point to be integrally formed to the end part of the PSC girder; and removing the end part support to enable the PSC girder having a slab to be supported by the bridge support installed in the lower structure of the bridge.</p> |
