The utility model discloses a luo liang expansion joint device is prevented to modulus formula belongs to bridge expansion joint technical field, including location respectively two symmetries set up move boundary beam on the accuse box, with the help of the pressure -bearing support with the supporting beam in compressing tightly that the support is spacing to move the accuse box and set up on supporting beam and be arranged in the roof beam between the roof beam of both sides, its key lies in: at supporting beam and move the accuse and be equipped with energy -absorbing limit structure between the box, in the structure in the accuse box is being moved to the location and lie in dog and the spacing spacing portion and the dog buffer block within a definite time at supporting beam of supporting beam one side or both sides. The utility model discloses beneficial effect is: come temporarily in the earthquake, after the flexible volume of expansion joint device reached the limit, the last spacing portion of supporting beam and dog cooperation compression buffer block played the effect of antidetonation energy dissipation, and the buffer block lost efficacy, and to hold the dog be that spacing portion on the supporting beam holds the roof beam body and in order to prevent that it from falling absolutely, reaches the roof beam of preventing falling and act on to the spacing portion in back, avoids leading to the fact the calamity.
