Detailed description of the invention
Referring to Fig. 1 ~ Fig. 6, ground described in the utility model locking-type movable rail and the speedway guardrail that comprises it are described in detail.
As shown in FIG. 1 to 3, ground described in the utility model locking-type movable rail is made up of the two identical rows arranged along road length direction, often arrange and assembled by multi-segmental, every bay structural comprises bumper assembly, to the passive column 3 of this bumper assembly, for installing the ground lock tube pipe 4 fixing this column 3, wherein, bumper assembly comprises the obstruction block 2 be assemblied on column 3, be assemblied in scab 21, the monophasic waveform joist steel crossbeam 1 be assemblied on this scab 21 of this obstruction block 2 column 3 side dorsad, utilizes bolt 5 that obstruction block 2 is arranged on the top of column 3.
Ground lock tube pipe 4 is made up of round steel pipe, and it is embedded in below express highway pavement usually in advance, and this ground lock tube pipe 4 is equivalent to a female steel pipe.As shown in Figure 6, on the tube wall of ground lock tube pipe 4, symmetry offers a pair first slideways 71 that are opening up and that axially arrange along it, and this first slideway 71 is almost formed in the whole length of ground lock tube pipe 4.The tube wall of ground lock tube pipe 4 offers in the bottom of each first slideway 71 second slideway 72 of the circumferencial direction extension along ground lock tube pipe 4, and the length of this second slideway 72 is 1/4th of the whole circumferential length of ground lock tube pipe 4.The bottom being positioned at the first slideway 71 of homonymy is crossing with the end vertical of the second slideway 72, in other words, namely looks from the direction perpendicular with the length direction of ground lock tube pipe 4, is positioned at the first slideway 71 and the L-shaped setting of the second slideway 72 of homonymy.It should be noted that the second slideway 72 forms rotating Vortex motion relative to the setting direction of the first slideway 71 with the lock pin 6 making to be positioned at not homonymy and is as the criterion.
Column 3 is also made up of round steel pipe, and it is equivalent to sub-steel pipe, and the external diameter of this column 3 is equal with the internal diameter of ground lock tube pipe 4.As shown in Figure 4 and Figure 5, the external peripheral surface of column 3 is provided with the lock pin 6 of a pair circle corresponding with aforementioned a pair first slideways 71, and this lock pin 6 extends along the radial outside of this column 3, and in the present embodiment, the length of lock pin 6 equals the wall thickness of ground lock tube pipe 4.
When ground locking-type movable rail is installed, first arrange along spaced multiple ground, road length direction lock tube pipe 4 on express highway pavement, the mode that this ground lock tube pipe 4 mainly adopts road surface water drilling to get core is carried out pre-buried, the top end opening of lock pin 6 on column 3 with the first slideway 71 on ground lock tube pipe 4 is aimed at and be entrenched in the first slideway 71, then column 3 is inserted in ground lock tube pipe 4 until lock pin 6 is connected to the bottom of the first slideway 71, then, rotating column 3 makes lock pin 6 slide along the second slideway 72, stop until Rotary cloumn 3 to 90 spends position, make column 3 and ground lock tube pipe 4 be formed thus to be engaged plug-in to be connected.Aforementioned bumper assembly installed by column 3, and after crossbeam 1 installs, column 3 can not vertically be extracted.
Ground described in the utility model locking-type movable rail is mainly applicable to Expressway Central Strip opening part, the crossbeam 1 of this ground locking-type movable rail and median barrier, obstruction block 2, column 3, the above structures in ground such as bolt 5 are identical, difference is the column 3 of median barrier is driving into type, below ground column is identical with more than ground, there is no ground lock tube pipe 4, like this, under ground locking-type movable rail is in installment state, ground locking-type movable rail and median barrier form that same crossbeam is identical to be connected, both one integrated mass, form ad eundem to connect with slotless design.
The center stand column of ground locking-type movable rail in the utility model and the point coincides of installation site are arranged, as shown in Figure 1, ground locking-type movable rail installation site L totally 30 meters long, every 4 meters is a sections, totally 7, column, overlaps from the position of both sides number the 4th root post and the center (from movable rail reserved location both sides number 15 meters) of installation site.
When there is vehicle collision, above-mentioned ground locking-type movable rail and median barrier play the effect of identical guiding, energy dissipating and integral protection, and cheap.When changing ground locking-type movable rail, opened by the bolt 5 at guardrail two ends, the bolt on interstitial segment column 3 is turned on, and uses slide plate to drag away.
Ground locking-type anti-collision movable guardrail in the utility model on Expressway Central Strip guardrail basis, carries out ground locking-type design and installation to reach the three large features such as same structure, same to anti-collision level, seamless link, strengthen the protective capacities of expressway safety facility, the perfect globality of traffic safety protection system.Ground locking-type movable rail and median barrier one integrated mass, exquisite composition, novel structure, easy construction, cheap, be suitable in speedway, urban road central separating belt opening place, the universal use in vehicle shunting place of charge station.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
Such as, in the above-described embodiments, as shown in Figure 6, the bottom of the first slideway 71 is crossing L-shaped with the end vertical of the second slideway 72, but not limited thereto, the bottom of the first slideway 71 also can intersect vertically in inverse-T-shaped with the middle part of the second slideway 72, or, bottom and second slideway 72 of the first slideway 71 are not limited to intersect vertically, and both also can intersect the angle of other angles.
Such as, in the above-described embodiments, the length of lock pin 6 equals the wall thickness of ground lock tube pipe 4, but not limited thereto, as long as the length of lock pin 6 meets the distance be greater than between column 3 external surface to ground lock tube pipe 4 internal face be less than or equal to the distance of column 3 external surface extremely between lock tube pipe 4 external surface.
Again such as, in the above-described embodiments, bumper assembly adopts shown in Fig. 3, but it is not limited thereto, purport of the present utility model is that column 3 and ground lock tube pipe 4 adopt lock pin 6 to be formed to be engaged to plug with the first slideway 71 and the second slideway 72 and be connected, and the concrete structure for the bumper assembly be arranged on column 3 does not limit.
