In this expansion joint, a toothed portion provided with a plurality of protrusions projecting toward each other at intervals in a seam longitudinal direction is formed at an upper end of each of the vertical substrates facing in the bridge axis direction. Are formed so as to be bent in a zigzag manner to form a wavy play extending in the longitudinal direction of the joint, and both ends of the seal plate are fixed to opposing inner surfaces of the vertical substrates.

る。[0003] The above-mentioned expansion joint is usually made to have a length of 1 to 2 m. Therefore, a plurality of expansion joints are connected and installed in the seam portion of the road bridge in the seam longitudinal direction. In this case, the seal plates of the expansion joints adjacent to each other in the longitudinal direction of the seam are in a state where they are merely abutted with each other, or in a state where a part thereof is overlapped, or in a state where they are separated from each other. There is a need to. As a means for this, a method is generally adopted in which a short connecting seal plate having a length of about 10 cm is crotch-bonded to both seal plates of adjacent expansion joints.

手を挿入することができず難しい。However, after installing the expansion joint at the road joint, the connecting seal plate must be inserted into the zigzag of the opposing tooth profile from the bent wavy play. In addition, since a wide insertion gap cannot be obtained, the insertion is difficult, and in some cases, the insertion cannot be performed. Also, the work of bonding the inserted connection seal plate and the seal plate of the expansion joint is difficult because the operator cannot insert his hand through the wavy play.

It is conceivable to perform a connection operation, and then raise the expansion joint so that the vertical substrate is vertical and fix it. However, when the total length of a series of connected expansion joints is long, it is difficult to raise the whole of the expansion joints at the same time and position them so as to have a corrugated play of a predetermined size.

したものである。SUMMARY OF THE INVENTION Accordingly, the present invention provides an expansion joint by forming a play gap wider than the corrugated play gap by partially cutting out the longitudinal end of the joint of the tooth profile of the expansion joint. Even after installation at the road joint, the connection of the expansion joint seal plates by the connection seal plate can be performed easily and reliably without water leakage by utilizing this play space. .

Formed, and each tooth profile part is bent in a zigzag manner and faces each other to form a wavy play extending in the seam longitudinal direction, and a seal plate is provided between the vertical substrates, and the seam longitudinal direction is provided. A road bridge expansion joint to be connected, wherein a part of the end of the tooth profile in the seam longitudinal direction is cut off, and both ends of the seal plate of both road bridge expansion joints adjacent in the seam longitudinal direction are crotched. A gap wider than the corrugated gap for inserting a connecting sealing plate for connecting the two sealing plates by overlapping is formed.

In view of the above, the length is preferably 5 cm or more, and the upper limit is preferably determined based on the tire width of the vehicle from the viewpoint of the running performance of the vehicle, for example, about 15 cm. In the case where the play is formed in both expansion joints adjacent to each other in the seam longitudinal direction, it is preferable that the play is connected in a straight line. In that case, the play at the end of each expansion joint is preferable. Is preferably 2.5 cm or more and 7.5 cm or less.
