PROBLEM TO BE SOLVED: To improve a reinforcing effect by moving a fixture for fixing a lattice material to the lower surface of a concrete structure in the direction perpendicular to a lattice material surface and adding a surface direction force to the lattice material. SOLUTION: A lattice material fixing tool 6 is composed of a fixing tool main body 7 having a guide slope 9 and an anchor 8. For attaching a reinforcing lattice material 5 to the lower surface of the floor board 1 or the like of a concrete bridge, the main body 7 is attached to the intersection part of the lattice material 5. Then, after the slope 9 is contacted with the lattice material 5, the anchor 8 is stricken into the floor board 1, and then by the action of the lower surface of the head part 10 of the anchor 8, the main body 7 is moved in the direction perpendicular to the surface of the lattice material 5. A surface direction force is applied to the lattice material 5 by the slope 9, and when the fixing tool 6 is attached by spreading the same in a plurality of places, a tension force is applied to the full surface of the lattice material 5. Further, polymer cement or the like is provided so as to cover the full surfaces of the fixing tool 6 and the lattice material 5. Thus, pre-stress is introduced to the lattice material and the floor board and the lattice material are made integral firmly. |
