PROBLEM TO BE SOLVED: To provide a steel form with a main reinforcement and a bridge floor panel construction method, by which a shorter site construction period and a less number of site skilled workers than in a conventional method are achieved, a prefabricating method with no scaffold and support required is improved, a light weight for easy handling and high rigidity to prevent the deflection of concrete when placed are realized and a cost increase is minimized. SOLUTION: A steel form 4 with a main reinforcement is placed on main beams 2 arranged in the bridge axial direction and then concrete is placed thereon to construct a floor panel. In this case, upper side main reinforcements 8 and lower side main reinforcements is double number are arranged on the upper face of a thin steel plate 7 to be perpendicular to the bridge axial directional and one upper side main reinforcement and two lower side main reinforcements are joined together via a pair of latticed bars 10 to form a set of space truss bars T, and the lower side main reinforcements are fixed to the thin steel plate. |
