The specific embodiment
As shown in Figure 1, wave beams of highway guardrail of the present utility model termination mainly is made up of roll bending device, breeze way and reinforcement section successively, wherein breeze way is made up of unhook restraint device, can lodge column and wave beams, strengthens section and is made up of column, suspension cable restraint device and waveform beam slab.
As Fig. 1, Fig. 2 and shown in Figure 3, the utility model breeze way roll bending device is made up of guide frame 1, baffle plate 2, arc plate 3, shear plate 4, floor 5, front baffle board 6 and cover plate 7.Form narrow extruding aditus laryngis between the linkage section of baffle plate 2 and arc plate 3, wave beams is by in the guide frame 1 insertion end head main body.Meet when hitting the termination when vehicle, move backward with vehicle the termination, and the aditus laryngis of being made up of arc plate 3 and plate washer 2 launches the wave beams extruding, and bend along arc plate 3 and to extrude from the main body of termination, extends back again.The arc shape of arc plate 3 can effectively be controlled the extruding end head main body wave beams direction of motion for backward, avoids wave beams to thrust in the car, for the passenger provides safety guarantee.
As Fig. 1, Fig. 4, shown in Figure 5, breeze way unhook restraint device of the present utility model comprises the unhook column 11 that can lodge, oblique rollering steel rope 13 and dentation restraining plate 14, the roll bending device fixedly installs unhook column 11 upper ends that can lodge again, oblique rollering steel rope 13 1 ends are fixed on the lower end of the column 11 that can lodge, be connected with the unhook column 11 that can lodge by a plate 12, junction plate 12 is fixed on the lower end of the unhook column 11 that can lodge by a stove bolt 9, junction plate 12 is provided with a hypotenuse simultaneously, hypotenuse is provided with semicircle opening, and a king-bolt 10 is fixed on semicircular opening and can lodges column 11 lower ends.Oblique rollering steel rope 13 is inclined upwardly backward and fixedlys connected with dentation restraining plate 14, and dentation restraining plate 14 edges have the tooth mouth of offering at inside rear portion, and connecting bolt 15 is fixed on the waveform beam slab by the tooth mouth.Dentation restraining plate 14 then is connected with oblique rollering steel rope 13 by adjustable bolt 16.
Meet when hitting the termination at vehicle, bottom unhook stove bolt 9 is cut off, the bottom of unhook column 11 is connected with bottom unhook king-bolt 10 by semicircular opening owing to can lodge, the unhook column 11 that can lodge flies out, the bottom constraint of oblique rollering steel rope 13 disappears, collision top, termination dentation restraining plate 14, and top dentation restraining plate 14 easily comes off, the unhook process is finished, and avoids injures and deaths to take place.When vehicle side impact guardrail, because the active force of cable wire is very little to the moment that bottom unhook stove bolt 9 produces, unhook stove bolt in bottom is difficult for being cut off, and the restraint device that therefore breaks off relations can provide stronger restraint forces.
As Fig. 1, shown in Figure 6, breeze way of the present utility model can lodge column by square column 19, cut off bolt 17 and the constraint swivel bolt 18 form.Square column 19 lower ends are provided with the connection stake be fixed on pavement edge, and column is provided with a constraint bolt 18 and and cuts off bolt 17 with being connected between the stake, square column 19 be connected between serve as spool to be rotationally connected to retrain bolt 18.
After the termination main body bumps against square column 19, to cut off bolt 17 and cut off, square column 19 serves as to fall down to the ground after axle rotates with constraint swivel bolt 18, and vehicle is passed through smoothly.
As Fig. 1, shown in Figure 7, reinforcement section suspension cable restraint device of the present utility model is made up of cable wire 20, cable wire top tie plate 21 and cable wire bottom dead bolt 22.Piling of square column 8 lower ends or pile anchoring are in ground, the top tie plate 21 that passes through of cable wire 20 is fixed on the wave beams, and the bottom is fixed on square column 8 lower ends by dead bolt 22, forms a kind of front end following, the rear end is in last heeling condition, for the normal reach guardrail provides enough restraint forcess.
Above-mentioned stove bolt 9, king-bolt 10, cut off bolt 17 and constraint bolt 18 can use pin to replace, and then formation and equivalent structure of the present utility model.
Breeze way roll bending device of the present utility model is provided with guide frame, extruding aditus laryngis and arc plate, wave beams is inserted in the guide frame, when vehicle is met when hitting the termination, because the effect of guide frame, the roll bending device moves along the corrugated beam barrier direction with vehicle, wave beams is extruded expansion during aditus laryngis by extruding, and from the roll bending device, extrude along the arc plate track, by the Texturized absorption vehicle collision of the expansion of wave beams energy, the wave beams that comes out from the roll bending device moves along garage's direction, has avoided the occupant is damaged.
Breeze way unhook restraint device of the present utility model act as central collision the time break off relations smoothly, with the anti-vehicle resistance of stumbling, guarantee during side impact that enough restraint forcess are arranged at the bottom, vehicle is met when hitting the termination, unhook stove bolt in bottom is cut off, because the bottom of unhook column is connected with bottom unhook king-bolt by semicircle orifice, the unhook column flies out, and the bottom constraint of cable wire disappears.Collision top, termination dentation restraining plate, top dentation restraining plate easily comes off, and the unhook process is finished.When vehicle side impact guardrail, because the active force of cable wire is very little to the moment that unhook stove bolt in bottom produces, unhook stove bolt in bottom is difficult for being cut off, and the restraint device that therefore breaks off relations can provide stronger restraint forces.
Breeze way of the present utility model can lodge column after the termination main body bumps against square column, cuts off bolt and is cut off, and square column serves as to fall down to the ground after axle rotates with the constraint swivel bolt, and vehicle passes through smoothly.
Reinforcement of the present utility model section suspension cable restraint device mainly by cable wire, cable wire top fix, the cable wire bottom fixedly forms, wherein cable wire top is fixing is connected with wave beams, the cable wire bottom is fixing to be connected with the column bottom, for the normal reach guardrail provides enough restraint forcess.
