It is formed to be equal to the dimension W2 between Bb and Bb. As shown in FIGS. 6 and 7, a plurality of reinforcing panels l7
The steel girder [ia. 6b with bolts l2, and the steel girder 8a of the concrete slab 8. After continuously covering the lower surface of the road bridge 7 in the longitudinal direction between 8b and integrally connecting the adjacent vertical ribs 15 with bolts t8, the concrete slab 8b is formed between the concrete slab 8 and the skin plate L6. A synthetic resin filler l3 is injected into the space. In the second embodiment described above, as in the first embodiment, peeling of the lower surface of the concrete deck 8 is effectively prevented and the concrete deck 8 is supported from the lower surface, thereby improving the service life of the road bridge 7. can be achieved. FIGS. 1l to 15 show a third embodiment of the method for reinforcing a concrete deck according to the present invention, in which the direction from one steel girder 6a to the other steel girder 6b is shown from the longitudinal end of the road bridge 7. The steel girder 6a. lfb
A horizontal rib 19a extending in the width direction of the road bridge 7 is provided on the lower surface of the skin plate 2l, which has a shape capable of coming into contact with the lower surface of the road bridge 7 and has a predetermined dimension in the longitudinal direction of the road bridge 7. 19b and vertical ribs 20a, 20b extending in the longitudinal direction of the road bridge 7 are fixed in a grid pattern to form a reinforcing panel 22. The reinforcement panel 22 has a dimension W4 in the width direction of the road bridge 7 that is the same as the steel girder 6.
a. It is formed to be equal to the dimension W2 between Bb and Bb. As shown in FIGS. 11 and 12, a plurality of reinforcing panels 22 are fixed to the steel girders 6a and 6b with bolts 12 so that adjacent skin plates 2l overlap each other, and the steel girders 6a and 6b of the concrete slab 8 are fixed to each other with bolts 12. 6b continuously covering the lower surface of the road bridge 7 in the longitudinal direction, and adjoining vertical ribs 20a.
After integrally connecting the 20b with bolts 23, a synthetic resin filler 13 is injected into the space formed between the concrete floor slab 8 and the skin plate 21. In the third embodiment described above, as in the first and second embodiments, peeling of the lower surface of the concrete slab 8 is effectively prevented, and the concrete slab 8 is supported from the lower surface to support the construction of the road bridge 7. It is possible to improve the service life. Figures i6 to 19 show a fourth embodiment of the concrete deck reinforcing method of the present invention, in which the direction from one steel girder 6a to the other steel girder 6b is shown from the longitudinal end of the road bridge 7. The steel girder 6a. 6b and has a shape that can come into contact with the lower surface of the road bridge 7 and has a predetermined dimension in the longitudinal direction of the road bridge 7} A horizontal rib 24a. 24b. 24c. 24d
