Document Type and Number:
Japanese Patent JP6697872
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a gap-filling material of an expansion device for bridges, the material that is superior in followability and workability against stretching without the occurrence of large reaction force due to shrinkage of a gap or protrusion to a surface.SOLUTION: A gap-filling material 10 of an expansion device for bridges is provided for engaging a pair of comb teeth together and is disposed in a gap around the comb teeth varied with the stretching to the bridge axial direction. The gap-filling material includes a body part 20 disposed between the tip of the comb teeth and the valley of the comb teeth opposed thereto, an end connection 30 for connecting adjacent bodies 20 to each other with the tip and the valley, and a bottom plate 40 for blocking between the body 20 connected with the end connection 30 and the end connection 30 and disposed in the lower end of the body 20 and the end connection 30. The gap-filling material is formed of an elastic member, and the body 20 is a hollow cross section shape and is pushed out in the gap from the bottom plate 40 and is formed in a disposing manner.SELECTED DRAWING: Figure 1
