Crumple seat 40；The crumple seat 40 includes both side plate 41 and the stiffening plate 42 being fixed between both side plate 41, the side plate 41
20 side of fence body is provided with a collision prevention girders mounting hole 41a, the side plate 41 connect side with fence body 20 and sets
It is equipped with shrinkable attachment device；The fence body 20 is made of two symmetrically arranged guardrail boards 21, and the guardrail board 21 is
Arc, arc-shaped concave middle part are provided with the lug boss 22 for fixing shrinkable attachment device, the lug boss 22 and shrinkable
Attachment device is connected by bolt 43, and the location hole 22a passed through for bolt 43, the guardrail are provided on the lug boss 22
It is provided with crossbeam mounting hole on plate 21, is provided with crumple mouth 24 on 21 arc convex of guardrail board of 22 top of lug boss；Institute
Stating top beam mounting base 30 is the hollow cylinder for connecting each guardrail board 21.In use, collision prevention girders, crossbeam and top beam are mounted on phase
Answer position, vehicle bumps against in the collision prevention girders on guardrail, install the crumple seats 40 of collision prevention girders also can stress, fix crumple seat 40 at this time
Bolt 43 can be destroyed to form shrinkable attachment device, if vehicle, still in runaway condition, collision prevention girders will be with crumple seat 40
It continuing to move to, is impinged upon in guardrail board 21 to fence body 20, errant vehicle can also impact the crossbeam of 22 lower section of lug boss simultaneously,
Collision prevention girders and lower crossbeam exert a force to guardrail board 21 at this time, since guardrail board 21 is arc, above top beam and lug boss 22
Under crossbeam collective effect, at the crumple mouth 24 of guardrail board 21 will become a separation, top by pulling force and lower section is hit
Power, guardrail board 21 are deformed to direction of traffic, and the arc of guardrail board 21 originally prevents vehicle from routing up bridge beam action, deformed
Effect is more prominent.Also, it, can be with when being safeguarded to guardrail in the case where just obtaining control after vehicle destroys crumple seat 40
Only crumple seat 40 is replaced.
In the present embodiment, the crossbeam mounting hole includes upper beam mounting hole 22b and lower beam mounting hole 22a, it is described on
Crossbeam mounting hole 22b is between lug boss 22 and pedestal 10, and the lower beam mounting hole 22a is located at lug boss 22 and top beam is pacified
It fills between seat 30, is provided with crumple groove above the lower beam mounting hole 22a.
In the present embodiment, the crumple groove 25 includes at least two, and the crumple groove 25 is along the cambered surface concave surface of guardrail board 21
It is arranged to arc convex direction interval, and height successively gradually decreases.25 one side of crumple groove can save material, another party
Face can also cooperate the further guide rail plate 21 of crumple mouth 24 to deform.
In the present embodiment, the shrinkable attachment device includes at least two stepped hole 41b and one for installing bolt
Through-hole 41c.Stepped hole 41b is because more weakness can first be destroyed deformation, and then crumple seat 40 is mounted on another through-hole 41c's
Bolt 43 destroys, and can provide and buffer twice.
In the present embodiment, 41 inner surface of both side plate and 20 two sides face contact of fence body of the crumple seat 40, the rank
Terraced hole 41b is located at the outer surface of both side plate 41, and the stiffening plate 42 is located at crumple seat 40 far from 20 side of fence body.It is processing
When, crumple seat 40 will carry out preprocessing, and stiffening plate 42 can not only increase crumple seat intensity, can also between distance side plate 41 into
Row limitation, facilitates preprocessing.When assembling, then crumple seat is installed in the railing main body being welded by bolt.
In the present embodiment, the stiffening plate 42 include upper reinforcing plate 42a and lower reinforcing plate 42b, the upper reinforcing plate 42a with
10 angle of pedestal is 80~90 °, and 42 outer surface of upper reinforcing plate is provided with reflecting piece 44, the light-illuminating of such vehicle at night
In reflecting piece 44, the effect of reminding bridge boundary line can be opened driver.
In the present embodiment, 20 lower end of fence body is provided with connecting plate 11, and the connecting plate 11 is located at two guardrails
Between plate 21, the connecting plate 11 is fixed on pedestal 10；20 two sides of fence body and 10 junction of pedestal, which are provided with, to be added
Strengthening tendons 12.Connecting plate 11 connects pedestal 10 and two pieces of guardrail boards 21, guarantee between guardrail board 21, fence body 20 and pedestal 10 it
Between the stability that connects.
In the present embodiment, the connecting plate 11 and reinforcing rib 12 are located at pedestal 10 close to 21 arc convex side of guardrail board.
Guardrail entirety center of gravity is biased to 21 cambered surface concave surface of guardrail board, therefore connecting plate 11 and reinforcing rib 12 are arranged in 10 middle line of pedestal
21 arc convex side of close guardrail board.
