CONCRETE SURFACE REINFORCING STRUCTURE AND METHOD AND NET-LIKE REINFORCEMENT MATERIAL MADE OF FIBER-REINFORCED RESIN

PROBLEM TO BE SOLVED: To provide a concrete surface reinforcing structure and method and a net-like reinforcement material made of a fiber-reinforced resin.SOLUTION: A plurality of sets of two vertical reinforcements 2 each of which consists of a set of two reinforcement materials 4 made of a fiber-reinforced resin arranged parallel to each other with a first distance B1 are disposed with a second distance B2 larger than the first distance B1, and a plurality of sets of two horizontal reinforcements 3 each of which consists of a set of two reinforcement materials 4 made of a fiber-reinforced resin arranged parallel to each other with a third distance B3 so as to intersect the sets of two vertical reinforcements 2 are disposed with a fourth distance B4 larger than the third distance B3, thereby obtaining a net-like reinforcement material 1 made of a fiber-reinforced resin which is integrally formed by fixing intersections of the sets of two vertical reinforcements 2 and the sets of the two horizontal reinforcements 3. The net-like reinforcement material 1 is fixed on a concrete surface by bolts or anchor bolts 12 through a spacer 16, and a mortar layer is formed so as to embed the net-like reinforcement material 1.
