士を接合するようになっている。2. Description of the Related Art An example of a vertical expansion and contraction device for a road bridge and a joining structure thereof are described in Japanese Patent Publication No. Hei 57-57923. This is provided with an outwardly projecting convex joint at one end in the seam longitudinal direction of the elastic member, and an inward concave concave joint at the other end, and the convex joint and the concave joint are provided. By fitting with the joining portion, the telescopic members of the adjacent vertical telescopic devices are joined to each other.

The concave joint portion is formed by providing a weir portion whose peripheral edge is integrally connected to the inner surface of the elastic member at a position inside the other end edge of the elastic member.

とが防止される。According to such a joint structure of the telescopic members of the vertical telescopic device, a substantial gap is formed between the telescopic members by the fitting of the convex joint and the concave joint. Water leakage from the top of the bridge to the bottom of the bridge is prevented.
Also, since the grooves of the telescopic members of each vertical telescopic device are independent of each other, even if sand, sealing material, or other fillers are put in the grooves, the fillers flow out to the adjacent telescopic members having a low gradient. Is prevented.

【発明が解決しようとする課題】しかし、上記竪型伸縮

ある。However, in the case of the above-mentioned vertical telescopic device, there is a problem that the weir portion forming the concave joint portion hinders the smooth deformation of the telescopic member due to the expansion and contraction of the road bridge.

端面板から剥離し易くなる。That is, although the weir portion is formed of an elastic sheet material such as rubber, the periphery is integrally connected to the inner surface of the groove-shaped elastic member to form a knot in the elastic member. . Therefore, when the distance between the facing end face plates is enlarged or reduced, the bottom of the groove-shaped elastic member moves up and down, whereas the weir portion has not only the bottom edge but also the side edge. Since it is connected to the elastic member, it cannot move up and down. For this reason, an abnormal deformation is caused at the boundary between the groove-shaped elastic member and the weir, causing a crack, or since the elastic member cannot be smoothly deformed, it is easy to peel off from the end face plate.

If the groove-shaped groove is extended inward from the edge of the elastic member and a weir is provided at the back of the groove, the deformation of the elastic member is not hindered at all. Have been found, and the present invention has been completed.

害することがない。In each of the first and second aspects of the present invention, the groove-shaped concave portion of the concave joint portion is continuous with the edge of the elastic member, but is folded back from the edge and overlaps with the elastic member. Therefore, the elastic deformation of the elastic member is not substantially inhibited. In addition, the weir portion of the concave joint portion is provided in a deep portion of the groove-shaped concave portion that is not restrained by the elastic member, and the periphery of the weir portion is not directly connected to the elastic member. Therefore, the expansion and contraction of the elastic member is not hindered.

Water leakage is prevented. In addition, since the expandable members of each vertical expansion and contraction device form independent grooves, even if the filler is put into the groove, the filler does not flow out to the lower slope.

Although 1 is connected to the edge of the elastic member 3, it is folded back from the edge and only overlaps with the elastic portion 31 of the elastic member 3, so that the elastic deformation of the elastic portion 31 is substantially inhibited. Never. Further, since the deep portion of the groove-shaped concave portion 51 is not constrained by the elastic member 3 at all, the weir portion 52 of the concave joint portion 5 provided in the deep portion prevents the elastic member 3 from expanding and contracting. It does not inhibit. Further, although the convex joint 4 is fitted into the concave joint 5, the weir 41 of the convex joint 4 is not directly connected to the elastic member 3, and the weir of the concave joint 5 is not connected. It is movable with respect to the elastic member 3 together with 52, and does not hinder the elastic deformation of the elastic member 3.
