APPARATUS FOR INTRODUCING COMPRESSIVE FORCE IN UPPER STRUCTURE OF A BRIDGE AND METHOD FOR CONSTRUCTING A BRIGE HAVING THE SAME

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bridge reinforcement apparatus for bridges and a method of constructing a bridge including the bridges, wherein the bridge apparatus includes a plurality of girders, A concrete slab installed on an upper portion of the girders and having a reinforcing structure in which a reinforcing bar is installed; A first tension unit connecting a longitudinal end of the concrete slab and the girder to introduce a compressive force to one side of the concrete slab while introducing a prestress to one side of the girder; And a second tension unit connecting the other end in the longitudinal direction of the concrete slab and the girder to introduce a compressive force to the other side of the concrete slab while introducing a prestress to the other side of the girder. According to the present invention, the bending moment and shearing force generated in the portion of the upper plate adjacent to the wall portion of the ramen bridge can be minimized, and the construction can be simplified and simplified.
