ABSTRACT:
A large resisting distortion and modularized comb-type bridge expansion joint, comprises at least two modules located parallel in the direction of a bridge's width, and each module includes a fixed comb plate (2) and a movable comb plate (1), which are respectively disposed on girders located at the two sides of the bridge expansion joint, said movable comb plate (1) crosses over the bridge expansion joint, both of said fixed comb plate (2) and said movable comb plate (1) have a plurality of comb teeth (22), (11) at their opposite ends, and the comb teeth (11) of said movable comb plate (1) interdigitate with the comb teeth (22) of said fixed comb plate (2), characterized in that the root of said movable comb plate (1) rotatablely joints with a seat (5) fixed on the girders, and the comb teeth (22) of said fixed comb plate (2) rotatablely joints with the root of said fixed comb plate (2), while, the middle of the comb teeth (22) of said fixed comb plate (2) is movably set on an underlay (6) fixed on the girders and can be shifted transversely relative to the underlay (6). In this invention, when the girders have transverse shift under the effect of the wind or other external forces, the movable comb plate and its comb teeth will rotate correspondingly and the comb teeth of the fixed comb plate will also rotate correspondingly, then the broken of the comb teeth will be avoided.
