About This Product

■Toe grid/toe meshLightweight and thin FRP lattice bars are made by integrally molding high-performance fibers such as carbon fiber and resin, and exhibit the same reinforcing effect as reinforcing bars.

Tow grid method (thickening/rolling method)

■The trump card for repairing and reinforcing concrete structuresTow Grid is a new type of FRP lattice reinforcement made by impregnating resin with high-performance continuous reinforcing fibers such as carbon and glass.

Features of toe grid

■Thin and lightBecause it has a very light specific gravity and the lattice intersections are on the same plane, its cross section is thinner than that of reinforcing steel. It is easy to transport, does not require heavy machinery, and is not limited by construction space.

■High reinforcement effectContinuous reinforcing fibers with high strength and high elasticity are arranged in two directions, so it can be expected to have the same reinforcing effect as reinforcing steel.

■No corrosionConstructed of reinforced fibers and resin with excellent chemical resistance, so there is no need to worry about rust. It is effective in preventing frost damage in cold regions and salt damage in coastal areas.

■Compliant with RC design methodReinforcement design can be easily performed using a method similar to that used for calculating reinforced concrete.

■Performance of reinforced fibersAmong various reinforcing materials, carbon fiber has particularly excellent performance in terms of tensile strength and elastic modulus. Depending on the required performance, glass fiber etc. can also be used.

■Construction methodThe tow grid is fixed to the existing concrete base using anchors, etc., and is integrated by spraying or hand painting with special polymer cement mortar, etc., and coated to the specified thickness.

■Toe grid construction example・Bridge
·tunnel
・Waterway
·others

It is also effective for reinforcing ports (piers), water and sewage systems (pipes, facilities), buildings (columns, beams, slabs, walls), etc.

Performance confirmation test

■Loading test of actual bridge deckThe reinforcement effect was confirmed by static loading tests and stress frequency measurements before and after toe grid reinforcement on actual bridge decks.

■Wheel load running fatigue testThrough wheel load running tests, we have confirmed that the fatigue life of floor slabs reinforced with tow grids to the level specified in the old specifications has been improved.
