Description

Bridge anti-collision structure

Technical Field

The utility model relates to a bridge construction technical field especially relates to a bridge anticollision structure.

Background

Both sides of the bridge are provided with guardrails to prevent vehicles from rushing out of the bridge. However, the general bridge guardrails are of a concrete structure or a steel structure and are fixedly installed on two sides of a bridge deck. The guard rail of this structure generates a large reaction force to the vehicle when the vehicle hits the upper surface, which may cause the vehicle to roll over, and the guard rail is easily broken.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a simple structure is provided, construction convenience is difficult to be knocked off, prevents that the vehicle from tumbling and has a bridge anticollision structure of sound insulation effect.

The utility model discloses a realize through following technical scheme:

the utility model provides a bridge anticollision structure, its includes bridge floor and buffer stop, the bridge floor both sides are equipped with concrete foundation, pre-buried many reinforcing bars on the concrete foundation and be equipped with concrete foundation pouring hole in embedded reinforcing bar department, buffer stop includes anticollision wall and buffer board, a plurality of anticollision wall pouring holes and spring pouring hole have been seted up on the anticollision wall, and the anticollision wall inboard is pre-buried to have a plurality of buffer spring, the reinforcing bar passes corresponding anticollision wall pouring hole, the buffer board is including the elastic panel that bonds in proper order, sound insulation board, backplate and borduring outward, and the buffer board is located the anticollision wall inboard and is flat mutually with the bridge floor.

Furthermore, a plurality of longitudinal anti-collision convex strips are integrally formed on the inner side of the elastic panel.

Optimized, the concrete foundation pouring hole and the anti-collision wall pouring hole are oppositely arranged and are larger than the diameter of the steel bar.

Preferably, the back plate is a metal plate and is welded and fixed with the buffer spring.

Further, a sliding block is fixedly arranged below the wrapping edge, a sliding groove is formed in the road surface, and the sliding block is clamped in the sliding groove.

The beneficial effects of the utility model

The utility model discloses a bridge anticollision structure protected has following advantage:

1. simple structure and convenient construction.

2. The anti-collision device is not easy to be broken and the vehicle is not easy to roll over after being collided.

3. Has sound insulation effect.

Drawings

FIG. 1 is a schematic view of the structure of the present invention;

in the figure, 1, a bridge deck, 2, a concrete foundation, 3, a concrete foundation pouring hole, 4, an impact wall, 5, a steel bar, 6, an impact wall pouring hole, 7, a spring pouring hole, 8, a buffer spring, 9, an outer wrapping edge, 10, an elastic panel, 11, a sound insulation plate, 12, a back plate, 13, an impact protruding strip, 14, a sliding groove and 15 sliding blocks are arranged.

Detailed Description

The utility model provides a bridge anticollision structure, its includes bridge floor 1 and buffer stop, the bridge floor both sides are equipped with concrete foundation 2, the concrete foundation is pre-buried to have many reinforcing bars 5 and is equipped with concrete foundation sprue hole 3 in embedded reinforcing bar department, buffer stop includes crashproof wall 4 and buffer board, a plurality of crashproof wall sprue holes 6 and spring pouring hole 7 have been seted up on the crashproof wall, and the crashproof wall inboard is pre-buried to have a plurality of buffer spring 8, the reinforcing bar passes corresponding crashproof wall sprue hole, the buffer board is including the elastic panel 10, sound insulating board 11, backplate 12 and the outsourcing limit 9 that bond in proper order, and the buffer board is located crashproof wall inboard and is flat mutually with the bridge floor.

Further, the inboard integrated into one piece of elastic panel has a plurality of vertical crashproof sand grips 13, promotes elastic panel's buffering effect to improve elastic panel's intensity.

Optimized, concrete foundation pouring hole and crashproof wall pouring hole set up relatively and are greater than the reinforcing bar diameter, make things convenient for the pouring construction.

Optimized, the backplate is metal sheet and buffer spring welded fastening, improves the intensity of buffer board and convenient being connected with the spring.

Further, the fixed slider 15 that is equipped with in bordure below, be equipped with spout 14 on the road surface, the slider card is located in the spout, makes things convenient for the installation and the removal of buffer board.

The utility model discloses a pair of bridge anticollision structure, anticollision wall and buffer board are prefabricated, in the construction, place the anticollision wall on the concrete foundation of bridge floor both sides and a plurality of embedded bar pass corresponding anticollision wall plug hole, the hole department is pour at the spring to the spring, the hole communicates with each other and perpendicular with anticollision wall plug hole to the spring, then pour, thereby make anticollision wall fixed mounting on the concrete foundation, and accomplish the fixed of a plurality of springs, then place the buffer board in the anticollision wall inboard, and with backplate and spring welded fastening can, the structure is fairly simple, and construction convenience is swift.

And because buffer stop includes anticollision wall and buffer board two parts, the anticollision wall is pour on the concrete foundation through embedded steel, and the vehicle appears the accident and hits the last back of buffer stop, can cushion through the buffer board, is difficult to take place to tumble to can not lead to the fact direct impact to the anticollision wall, lead to the fact the anticollision wall to destroy. The buffer plate is damaged by collision only by replacing the buffer plate, so that the maintenance is convenient and the cost is lower.

Simultaneously because the buffer board is including the elastic surface board, sound insulation board, backplate that bond in proper order and bordure outward, elastic surface board and sound insulation board itself have certain cushioning effect, cushion through the spring again moreover, and the security is stronger to certain sound insulation function has.

To sum up, the utility model discloses a bridge anticollision structure who protects, simple structure, construction convenience is difficult to be knocked off, prevents that the vehicle from tumbling and has the effect that gives sound insulation.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
