PURPOSE: To prevent a floor slab from being damaged under the heavy condition of traffic, and to improve labor-saving for form members, shortening of a construction period, safety, and profitability in the time of its construction. CONSTITUTION: A space truss-like reinforcement 2 wherein one upper chord member 7 and two lower chord members 8 are provided and spaces between the upper chord member 7 and the lower chord members 8 are connected with two sets of lattice members 9 bent in wave shape, is set up. A plurality of the reinforcements 2 are arranged parallel to each other and are joined to a steel plate 1 for a form. Main reinforcements 3 at the underside and distribution bars U at the underside are arranged above the steel plate 1, the distribution bars 5 at the upside and main rainforcements 6 at the upside are progressively arranged above the upper chord members 7 of the truss-like reinforcements 2, and reinforcements for a floor slab A which are also used as a form panel are set up. A unit of the reinforcements for the floor slab A is placed on a main girder for a bridge and concrete is placed thereon. |
