Finally, the outside that guard plate 3 kept away from the bridge guardrail is connected with crashproof pad 4. Namely, one side of the protection plate 3, which is close to the motor vehicle lane, is connected with the anti-collision pad 4, so that the vehicle firstly collides with the anti-collision pad 4 when colliding with the sidewalk, and the protection of the bridge sidewalk and the bridge guardrail can be further achieved due to the buffering effect of the anti-collision pad 4. The connection mode of the protection plate 3 and the crash pad 4 can be a connection mode of bolts, screws and the like.

According to the bridge protection structure, the plurality of positioning plates are inserted into the pavement step body, the mounting plates are arranged on the surface of the pavement step body, and the plurality of second mounting holes on the mounting plates correspond to the plurality of first mounting holes on the positioning plates in a one-to-one concentric manner, so that the bridge protection structure is mounted; meanwhile, the protection plate is arranged on one side far away from the bridge guardrail, so that the sidewalk is located between the bridge guardrail and the protection plate, and the protection of the sidewalk and the bridge guardrail is achieved. In addition, set up the anticollision pad in the outside that bridge guardrail was kept away from to the guard plate for first collide to the anticollision pad when the vehicle hits to the pavement, further protected bridge pavement and bridge guardrail.

In other embodiments, as shown in connection with fig. 1 and 3, the mounting plate 2 is provided with a protecting portion 5 at a side far away from the bridge railing, the protecting portion 5 extends along the length direction of the bridge, and the protecting portion 5 is used for wrapping around the edge of the step of the pavement of the bridge. In particular, the protection portion 5 may be an elastomer shaped like angle steel, it will be understood that, in other embodiments, the protection portion 5 may be a structure with other shapes, and when the protection portion 5 wraps around the edge of the step of the bridge pavement, the protection portion may protect the step of the pavement from being impacted, and may protect a vehicle running on the edge of the step from being scratched. The guard 5 may be connected to the mounting plate 2 by a screw connection or other connection.

Further, the side of the guard portion 5 away from the mounting plate 2 has a circular arc-shaped structure. Namely, the side of the protection part 5, which is close to the motor vehicle lane, is arranged in a circular arc shape, so that friction can be reduced, sharp corners are avoided, and vehicles running on the edge of the step are further protected.

In some embodiments, the locating plate 1 is attached to the side of the guard 5 near the bridge railing. By this arrangement, on the one hand, when the positioning plate 1 is inserted into the step body, the mounting plate 2 can be simultaneously mounted on the surface of the step, and the protecting part 5 can be wrapped on the edge of the step, so that the mounting step is saved and the working efficiency is improved. On the other hand, when processing the protective structure of this bridge, can be earlier with mounting panel 2, guard portion 5 and locating plate 1 connect well then unified punching again, be convenient for make first mounting hole 11 and second mounting hole 21 concentric, improve machining precision, do benefit to the installation. Specifically, the positioning plate 1 and the guard portion 5 may be connected by screw connection or integrally formed connection.

As shown in fig. 3, the upper portion of the mounting plate 2 is connected with a plurality of mounting posts 6, the bottom side of the protection plate 3 is provided with a plurality of third mounting holes 31, and the plurality of third mounting holes 31 are sleeved outside the plurality of mounting posts 6 in a one-to-one correspondence manner. Specifically, the mounting post 6 may be disposed on a side of the mounting plate 2 away from the bridge railing, the depth of the third mounting hole 31 may be equal to the length of the mounting post 6, and the diameter of the third mounting hole 31 may be smaller than the diameter of the mounting post 6, so that the third mounting hole 31 and the mounting post 6 form an interference fit, thereby enabling the protection plate 3 to be more firmly mounted on the mounting plate 2. The mounting post 6 and the mounting plate 2 may be connected by screw connection or interference press fitting.

In this embodiment, the number of the mounting posts 6 is two, the two mounting posts 6 are respectively connected to two ends of the mounting plate 2 along the bridge length direction, and correspondingly, the number of the third mounting holes 31 on the protection plate 3 is also two. Of course, in other embodiments, the number of the mounting posts 6 may be plural, as long as the number corresponds to the number of the third mounting holes 31.

As shown in fig. 4 and 5, a plurality of limiting posts 41 are disposed on a side, connected to the protection plate 3, of the protection plate 4, a plurality of limiting holes 32 are disposed on a side, facing the protection plate 3, of the protection plate 4, the plurality of limiting posts 41 are inserted into the plurality of limiting holes 32 in a one-to-one correspondence manner, through holes 411 are formed in the limiting posts 41, and when the limiting posts 41 are inserted into the limiting holes 32, the through holes 411 are concentric with the third mounting holes 31. In this embodiment, the number of the limiting posts 41 is two, and correspondingly, the number of the limiting holes 32 is also two. Two spacing posts 41 set up respectively at the both ends of crashproof pad 4 towards guard plate 3 one side, and when crashproof pad 4 assembled on guard plate 3, through-hole 411 and the third mounting hole 31 on the spacing post 41 are concentric, therefore mounting post 6 can pass through-hole 411 to further play spacing effect to crashproof pad 4. The diameter of the limiting post 41 is larger than that of the through hole 411, so that a safe distance is reserved between the through hole 411 and the edge of the limiting post 41, and the limiting post 41 is prevented from being broken due to the thin wall. The length of the spacing post 41 can be less than the thickness of the guard plate 3 in the bridge width direction, and the length of the spacing post 41 can be equal to the depth of the spacing hole 32, so that the arrangement can prevent the anti-collision pad 4 from extending out of the guard plate 3 after being assembled on the guard plate 3, thereby improving the safety of pedestrian running.

Further, two sides of the protection plate 3 along the length direction of the bridge are respectively provided with a T-shaped groove 33 and a T-shaped protruding block 34, and the T-shaped protruding block 34 is used for being clamped with the T-shaped groove 33 on the adjacent protection plate 3. When the length of the bridge pavement is longer, the T-shaped protruding blocks 34 on the protection plates 3 can be clamped with the T-shaped grooves 33 on the next adjacent protection plates 3, so that the length of the bridge protection structure is extended.
