PROBLEM TO BE SOLVED: To provide a sealing structure for a joint gap between floor slabs at a wheel guard part, a sealing material and a sealing method that use a simple member for significantly reducing costs, enhancing workability and significantly curtailing work time.SOLUTION: A sealing structure is installed to protrude upward at a prescribed height from a road surface of a road bridge, the sealing structure being for a joint gap between floor slabs at a wheel guard part. A sealing member is inserted into the joint gap from outside and fitted for installation, the sealing member including a non-permeable first elastic deformation part bonded with an adhesive to one edge wall of a wheel guard part that faces each other on both sides of the joint gap, and a non-permeable second elastic deformation part connected integrally to the first elastic deformation part, the second elastic deformation part being more elastically deformable than the first elastic deformation part and coming into elastic contact with the other edge wall of the wheel guard part.SELECTED DRAWING: Figure 1 |
