Problems solved by technology
In this way, the movable comb body has a relatively long length because it needs to span the expansion joint of the bridge, and its manufacturing cost is relatively high. The intersecting comb teeth also occupy a certain length; at the same time, since the longitudinal expansion and contraction can only be completed on the surface of the beam body, the length of the comb teeth on the fixed comb plate and the movable comb plate is very limited, which greatly limits the expansion and contraction of the bridge expansion joint device. limit

Embodiment Construction
[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0018] As shown in Figures 1 to 6, the comb-type bridge expansion joint device includes fixed combs 2 and movable combs 3 respectively arranged on the beam body 1 on both sides of the bridge expansion joint 11, wherein the movable comb 3 is placed on the bridge Above the expansion joint 11, the fixed comb plate 2 and the movable comb plate 3 are respectively provided with comb teeth 21, 31 at their respective opposite ends, and are intersected and spaced apart from each other, and the comb teeth 31 on the movable comb plate 3 are located on the bridge Above the expansion joint 11;
[0019] The movable comb 3 is covered with a dust-proof cover 4, under which the dust-proof cover 4 is fixed under the side away from the root of the movable comb 3, and the buffer 5 is embedded in the movable comb. In the interval between the adjacent comb teeth 3...

The invention discloses a comb bridge expansion joint mechanism, comprising fixed comb plate (2) and movable comb plate (3) on the bilateral beams (1) of bridge expansion joint (11) respectively. Wherein movable comb plate (3) is installed on the bridge expansion joint (11) and combs (21, 31), arrayed crossly in distance to each other, are set on the corresponding ends of fixed comb plate (2) and movable comb plate (3). And combs (31) of movable comb plate are positioned on bridge expansion joint (11). Compared with prior technology, bridge expansion movement in longitudinal direction, accomplished on bridge expansion joint, breaks through the present technology constraint that expansion movement of crossed combs between movable comb plate and fixed comb plate corresponding to each other must be finished on beam surface. Body length of movable comb plate is shortened widely and production cost is decreased while beam expansion quantity in longitudinal direction is guaranteed.
Description
technical field [0001] The invention relates to a bridge expansion joint device, in particular to a comb-shaped bridge expansion joint device. Background technique [0002] Among the existing bridge expansion joint devices, a comb-type expansion device that uses a fixed comb and a movable comb is a better one. The movable comb includes a body and comb teeth, and the body of the movable comb is located in the bridge telescopic The comb teeth of the movable comb are matched with the comb teeth of the fixed comb and located above the beam body. In this way, since the expansion and contraction movement of the bridge is completed by the movable comb arranged above the expansion joint of the bridge, there is no longitudinal transition gap , so that the bridge deck and the road surface are connected into a whole, the shockproof performance is good, and the vehicle runs smoothly and comfortably. As my previous application, the application number is the Chinese invention patent "Ass...
