Description
Technical field
The utility model belongs to Highway bridge technique field, is related to a kind of guardrail, and in particular to a kind of highway bridge safety
Anti-collision guardrail device.
Background technique
Bridge is swept away when to prevent automobile from accident occurs, and anticollision barrier to be usually installed on bridge.Currently, highway in China is more
Using armored concrete wall guardrail and guardrail wires, existing highway bridge guardrail generallys use reinforced concrete anticollision barrier, when
When vehicle unexpected situation occurs and strikes anticollision barrier, due to being mostly to be rigidly connected between guard rail, itself do not have any
Buffer function, after accident, which occurs, for automobile knocks, the impact force of generation is very big, vehicle and the equal well damage of anticollision barrier, very
Certain threat can be extremely brought to the personal safety of occupant.
Further, since inertia is big when vehicle is run, simple stiff safety fence is largely single support rod, is easy by vehicle
It breaks, falls the major accident of bridge.
Utility model content
The problems in background in view of the above technology, the utility model aim are to provide a kind of highway bridge safety anti-collision barrier
Device, protection effect is good, highly-safe.
In order to achieve the goal above, the technical solution adopted in the utility model are as follows:
A kind of highway bridge safety anti-collision barrier device, including column, crossbeam, girder steel connector and fixing seat, it is described vertical
Column is fixed on the fixing seat, and the crossbeam and the girder steel connector are connected between the adjacent column, the cross
Beam is located at the front end of the girder steel connector, and the girder steel connector is fixed on the column by clip；
Multiple groups prefabricated steel is equipped with inside the column, the prefabricated steel is equipped with ellipse hole, by described logical
Hole is through setting sliding bar；
The column is equipped with aperture, and the both side ends of the crossbeam pass through the aperture and the fixed company of the sliding bar
It connects.
Further, the clip is spaced apart with the aperture on the column.
Further, the width of the aperture is greater than the width of the crossbeam；The length of the aperture is equal or slightly larger than
The length of the through-hole.
Further, the prefabricated steel is fixed on the column inner wall.
Further, the girder steel connector is arcuate structure.
Further, the sliding bar is equipped with positioning wedged block.
The utility model has the technical effect that
The anti-collision guardrail device of the utility model, strong shock resistance are hit first when guardrail on car hit surprisingly occurs
Crossbeam is hit, crossbeam will drive ellipse hole length direction (i.e. automobile direction of advance) of the sliding bar in prefabricated steel and move
Dynamic, until sliding bar touches through-hole the other end, this process has reached good buffer function, reduces vehicle to guardrail
Impact force, the fixed crossbeam of sliding bar for arriving to through-hole bottom end later will continue to play the role of stopping vehicle, reach secondary
Buffer function, in the case of impact force spends big, even if crossbeam is damaged, but girder steel connector in its back-end will continue to stop
Automobile plays Intercepting effects again, reduces the harm of automobile collision accident.

Specific embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with attached drawing.It should be understood that herein
Described specific embodiment is only used for describing and explaining the present invention, and is not intended to limit the utility model.
Referring to attached drawing 1-3, a kind of highway bridge safety anti-collision barrier device, including column 1, crossbeam 2, girder steel connector 3
With fixing seat 4, the column 1 is fixed in the fixing seat 4, and the crossbeam 2 is connected to adjacent with the girder steel connector 3
Between the column 1, the crossbeam 2 is located at the front end of the girder steel connector 3, and the girder steel connector 3 is fixed by clip 5
On the column 1；
Multiple groups prefabricated steel 6 is equipped with inside the column 1, the prefabricated steel 6 is equipped with ellipse hole 7, passes through institute
Through-hole 7 is stated through setting sliding bar 8；
The column 1 is equipped with aperture 11, and the both side ends of the crossbeam 2 pass through the aperture 11 and the sliding bar 8
It is fixedly connected.
When guardrail on car hit surprisingly occurs, crossbeam 2 is struck first, crossbeam 2 will drive sliding bar 8 along prefabricated steel
7 length direction of ellipse hole (i.e. automobile direction of advance) on 6 is mobile, until sliding bar 8 touches 7 the other end of through-hole,
This process has reached good buffer function, reduces vehicle to the impact force of guardrail, arrives to the sliding of 7 bottom end of through-hole later
The fixed crossbeam 2 of bar 8 will continue to play the role of stopping vehicle, reaches secondary buffer, big feelings are spent for impact force
Condition, even if crossbeam 2 is damaged, but girder steel connector 3 in its back-end will continue to stop automobile, play Intercepting effects again, reduce
