HIGH STRENGTH REINFORCED CONCRETE PRECAST PANEL

PROBLEM TO BE SOLVED: To shorten a period of construction work by producing a precast slab efficiently at a low cost and permitting a quick construction work for concrete pavement by using the precast slab, when carrying out a concrete paving for a wide area such as pavement for an airport. SOLUTION: This rectangular plate-shaped or square plate-shaped precast slab 1 is fixed with diagonal bars 4 between the main reinforcement 2, 2 at the upper surface sides and the main reinforcement 3 at the lower surface side laid at predetermined intervals in the longitudinal direction of the precast slabs 1, thereby forming trusses and constitute a truss bars 5 having a V-shaped cross section. The truss-reinforcing bars 5 are laid at predetermined interval in a width direction of the precast slab 1. In addition, the precast slab 1 is formed by placing high strength concrete R.
