Description
Technical field
This utility model is related to the anti-collision facility of highway and bridge, more particularly to a kind of reinforced ring ripple joist steel guardrail.
Background technology
With the fast development of highway in China construction and communication, traffic safety is faced with severe situation, anticollision barrier
As a kind of safety devices, important protective action is played to the traffic safety of highway and bridge.And traffic safety at present sets
Apply field, the utilization rate of traditional double corrugated beam barrier occupies more than 95% market share, and this self state of guardrail form opens
Begin to flourish and use till today always when building highway, with the progressively development of China's road design and its construction level, traditional wave beams
The limitation of guardrail is more prominent：
1st, the unicity of guardrail height.Vehicle in China's road driving, from large, medium and small type and passenger vehicle and lorry, car
Type and technical parameter are more and more abundanter, and traditional double wave beam guardrail simply simply adopts the guardrail board conduct of one piece of fixed dimension
Crossbeam, and guardrail board width and height are all fixing, cannot take into account large car and compact car not from height of interception at all
Same height of interception requires.
2nd, the unicity of guardrail rigidity.Traditional double wave beam guardrail only to be realized both anti-large cars by one piece of guardrail board and to prevent again
The purpose of compact car, and the collision energy that large and small type vehicle has an accident when colliding guardrail is widely different, guardrail board sets in thickness
Put and all guarantee first to intercept large car, and compact car has an accident collision guardrail, traditional corrugated beam barrier lacks anti-
Flexibility needed for the in-car driver and crew's safety of shield and pooling feature.
3rd, the cost of guardrail., in order to increase the impact resistance of crossbeam, crossbeam lower edges are all for traditional double wave beam guardrail
Aduncate multilamellar wavy shaped configuration can be set to, and steel plate width and thickness larger, this design undoubtedly increased horizontal stroke
The consumptive material of beam, increases cost.
