<p>The present invention relates to a wide PC composite girder which cures concrete on a molded steel plate with a cover structure to form the wide PC composite girder to reduce the slab point gap and the floor height of the small and medium girder bridge to effectively arrange a horizontal member and be used for a composite construction beams. The present invention includes: an upper plate formed by punching multiple holes through; a lower opening including side plates which are arranged on both ends of the upper plate in the width direction and are extended in a downward direction and formed by cutting the lower end of the side plates; a center opening which is formed to be spaced apart from the upper and lower ends of the side plates; the molded steel plate which is formed by merging the upper openings formed on the coupling area of the upper and side plates; and a lower concrete unit which is formed to embed the lower end of the side plates of the mold steel plate by a predetermined depth and to be wider than the upper plate in the width.</p> |
