Description
Describe
The present invention relates to safety screen or guardrail field that highway or speedway are used.The safety screen of " guardrail " type is known at present, and it comprises the stave of a level, or longeron, and this longeron can comprise the corrugated sheet steel bar that is installed on column or the pillar.When vehicle with relative baffle plate longitudinal extension direction was not too wide track corner impact, these safety screens showed quite safe and or the result of precognition.Yet for can be easily near road or for other reason, it be inconceivable building a continuous guardrail from start to finish on the starting point of highway and the whole highway between terminal point.Thereby guardrail will be made the long section more or less with end inevitably.Although statistics shows that guardrail shows quite satisfied performance when collision occurs in the guardrail mid portion, but show equally vehicle collision in the end of baffle plate or terminal incidence more and more higher, because kinetic energy is very high when baffle plate longitudinal rigidity height and vehicle high-ball, its result almost always serious with miserable.In addition, the height of end also may be dangerous.
Thereby people's notice begins to turn to the impact absorption problem when central collision is to safety screen recently.
One solution that extensively adopts comprises that the end portion that makes baffle plate tilts earthward downwards; This can prevent that vehicle from central collision taking place in a risk altitude and baffle plate end, but may cause the vehicle built on stilts and even reach dangerous height.
Other at present known solution relate to and can come endergonic baffle plate end by flexible, described end comprises the various baffle part that vertically interfix successively by the bolt of the calibration that engages with groove in each baffle part; At least endways the part baffle plate is double-deck, and every pair of parallel portion of guardrail is supported by pin, and pin has a through hole at the height of determining, can bearing the impact of vertical baffle, but ruptures under the percussion of default size longitudinally at baffle plate.Vehicle makes screw and pillar fracture to the impact of end, and each several part is nested in mutually.The known end of this pattern is widely used in some state of the U.S., yet they but have a shortcoming, because the necessary extra high timber of use cost, even timber can obtain in the locality, the cost of this baffle plate also has been than higher; If timber will be come from other local fortune, the cost of pillar will be high not be dared to inquire to making us so, can not reparation after also wanting to bump they.In addition, the rigidity of pillar has been too high in a word and is relatively more dangerous.
Prior art also comprises a kind of speedway safety screen made from the wall scroll arch section, and its end is equipped with a top of widening that has a roll system.To terminal end, in the time of promptly on the top, slide along bonding jumper in this top in vehicle collision, and it flattens bonding jumper when sliding when rolling; Energy absorption is that the distortion by bonding jumper provides.
A modification of this system comprises the end on a band top, and wherein the top has many special cuttves, and when car crass took place, cutter moved along the bar of guardrail, makes cutter that guardrail is cut into thin slice.Here energy absorption is that vertical cutting by bar provides.
The shortcoming of these two kinds of systems in back is that it is difficult to calibration and cost height in a word.
Prior art also comprises so-called impact-attenuating device.This is a kind of device that is used to protect certain objects, this certain objects be considered to traffic hazard or be in danger position.The impact-attenuating device is that with the difference of end their better performances and cost are higher.In fact, end only just works when it is connected on the safety screen, even and the impact-attenuating device still can work when it is isolated, protection dangerous but narrower object, as the end of the bridge pier or the parapet of bridge.
