Background technique

At present, bridge expansion devices used in bridge engineering have many structures, among which the comb-shaped bridge expansion device is more common. For the comb-shaped bridge expansion device, in order to ensure the load-bearing and deflection resistance of the comb part of the device, each comb in the comb structure must maintain a certain width. Since the combs are interlaced, the combs The gap between the combs is also relatively large, and the resulting problem is that when non-motor vehicles (especially narrow-wheeled bicycles or electric vehicles) pass by, the wheels may sink from the gaps between the comb teeth, thereby causing traffic Security risks. In order to prevent the wheels of non-motor vehicles from falling into the gaps of the comb teeth, structural improvements are generally carried out by reducing the gaps between adjacent comb teeth. However, as mentioned above, after the comb teeth gaps are reduced, the width of each comb tooth The size also needs to be reduced accordingly, which will lead to a reduction in the load-bearing and deflection resistance of the comb part of the telescopic device, thereby bringing hidden dangers to the safety of the bridge.
