Claims

[Scope of utility model registration request]

A main body member made of durable rubber and extending in the horizontal direction; an upper metal plate buried in the upper center of the main body member so as to extend in the horizontal direction; lower metal plates respectively connected to the lower sides of the main body member; and the main body member. A groove formed from the lower surface to the upper metal plate between the lower metal plates in the center of the main body member, a groove formed from the upper surface of the main body member to the lower metal plate on both sides of the upper metal plate, and a groove extending from the lower metal plate, respectively. An expansion joint having an anchor bolt device having a plurality of anchor bolts, wherein each lower metal plate has a horizontal portion formed horizontally on the outside, and a horizontal portion that descends toward the inner end following the horizontal portion. The anchor bolt device includes an upper threaded member operated from above the horizontal portion of the lower metal plate, and is threadedly engaged with the upper threaded member and has or is coupled with an anchor bolt. 1. An expansion joint comprising: a lower threaded member having a lower threaded member, the lower end of the lower threaded member being no lower than the lower end of the inclined portion of the lower metal plate.
