<p>The present invention relates to a curved Y-shaped bridge support comprising PC steel wires which are effective for bridge span lengthening and load transferring. The curved Y-shaped bridge support comprising the PC steel wires according to the present invention comprises: a lower bridge support coupled to an upper portion of a bridge support foundation; a first upper bridge support and a second upper bridge support which are coupled to an upper portion of the lower bridge support, and each of which branches out in a curved manner in the lengthwise direction of a bridge; a middle girder coupled so as to overlap with a portion on top of the first upper bridge support and the second upper bridge support, thereby connecting the first upper bridge support and the second upper bridge support, wherein the middle girder protrudes farther upward than the upper end of the first upper bridge support and the second upper bridge support, and is hollow on the inside so as to have a box form; and PC steel wires provided so as to penetrate through two ends on the upper portions of the first upper bridge support and the second upper bridge support and under the middle girder.</p> |
