Abstract
The utility model relates to a safety guardrail with air bags, which comprises an upper buffer unit and a lower buffer unit, wherein the upper buffer unit and the lower buffer unit are arranged alongone side, near a road,ofan upright post (1); the upper buffer unit comprises a first corrugated steel plate (21), a second corrugated steel plate (22) and a rubber pad (4); the first corrugated steel plate and the second corrugated steel plate are symmetrically combined together to form a cavity therebetween; the rubber pad is arranged between the first corrugated steel plate and the upright post; the first corrugated steel plate and the rubber pad are anchored on the upright post through bolts; the cavity formed by combining the first corrugated steel plate and second corrugated steel plate is filled with air bags (6); the lower buffer unit comprises an air bag pocket (3), which is also filled with air bags (6) and is bonded to the upright post through a bonding layer (5). The safety guardrail provided by the utility model has an excellent anti-collision effect and is applicable to the technical field of highway engineering.
Description
Technical field
The utility model relates to a kind of safety barrier with air bag, belongs to the technical field of highway engineering.
Background technology
Safety barrier has a wide range of applications in highway engineering, especially, in the both sides of speedway and the import department of charge station, is all provided with the safety barrier that prevents vehicle collision and gun off the runway.Common safety barrier can be divided into two kinds of stiff safety fence and semi-rigidity rails.So-called stiff safety fence, is generally the pier stud being formed by concreting, is spaced at the both sides of highway.Although stiff safety fence can prevent that vehicle from gunning off the runway effectively, due to its huge rigidity, with vehicle collision after tend to make vehicle to suffer great damage, also likely jeopardize the life security of automotive occupant.Therefore, stiff safety fence seldom appears at the both sides of speedway, just applicable to some extent in the both sides of the short distance runways such as such as charge station entrance.The inner side that corrugated sheet steel is fixed on column by the general employing of semi-rigidity rail forms, as shown in Figure 1.But this guardrail absorbs the limited in one's ability of collision energy, in the situation that collision is more violent, can not play the effect of a large amount of absorption collision energies.
Therefore, in prior art, need a kind of security protection performance good, can not bring the very safety barrier of macrolesion to vehicle simultaneously.
Utility model content
The utility model provides a kind of safety barrier with air bag, and it can overcome above-mentioned defect of the prior art.
According to the safety barrier with air bag of the present utility model, comprise the upper buffer unit and the lower buffer unit that arrange near a side of highway along column, upper buffer unit comprises the first corrugated sheet steel, the second corrugated sheet steel and rubber packing, the first corrugated sheet steel and the second corrugated sheet steel combine symmetrically and form cavity therein, rubber packing is arranged between the first corrugated sheet steel and column, the first corrugated sheet steel and rubber packing on column, are filled with air bag at the first corrugated sheet steel and the second corrugated sheet steel in the cavity in conjunction with formation by bolt anchoring; Lower buffer unit comprises gas skirt bag, is also filled with air bag and is bonded on column by tack coat in gasbag.
Preferably, can be at the arranged outside colligation band of gasbag, with by gasbag securely colligation on column.The first corrugated sheet steel and the second corrugated sheet steel can link together by the conjunction that is arranged on upper and lower two ends.
More preferably, in the cavity of the first corrugated sheet steel and rubber packing formation, also can be filled with air bag.Side at the second corrugated sheet steel or gasbag can arrange reflecting strips.
Adopt the safety barrier with air bag of the present utility model, not only anticollision performance is good, and can also reduce the loss of vehicle in collision accident.

Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, hereinafter in connection with accompanying drawing, embodiment of the present utility model is elaborated.It should be noted that, in the situation that not conflicting, the feature in embodiment and embodiment in the application can be combined mutually.
Referring to Fig. 2 and 3, wherein show according to the safety barrier with air bag of the present utility model, it comprises the upper buffer unit and the lower buffer unit that arrange near a side of highway along column 1.Upper buffer unit comprises the first corrugated sheet steel 21, the second corrugated sheet steel 22 and rubber packing 4, the first corrugated sheet steel 21 and the second corrugated sheet steel 22 combine symmetrically and form cavity therein, rubber packing 4 is arranged between the first corrugated sheet steel 21 and column 1, and the first corrugated sheet steel 21 and rubber packing 4 is anchored on column 1 with bolt.In cavity in conjunction with formation, be filled with air bag 6 at the first corrugated sheet steel 21 and the second corrugated sheet steel 22.The first corrugated sheet steel 21 and the second corrugated sheet steel 22 can link together by the conjunction that is arranged on upper and lower two ends.
Lower buffer unit comprises gasbag 3, is also filled with air bag 6 in gasbag 3.Gasbag 3 is bonded on column 1 by tack coat 5, is also provided with colligation band 7 in the outside of gasbag 3, with by gasbag 3 securely colligation on column 1.
As shown in Figure 2, two adjacent upper buffer units can link together by connector 8 in the position of column 1, thereby form continuous safety barrier along the both sides of highway.Certainly, connected mode and the position of two adjacent upper buffer units can be selected according to actual needs, and are not limited to the embodiment shown in Fig. 2.
Preferably, can also in the cavity that the first corrugated sheet steel 21 and rubber packing 4 form, also fill air bag, to strengthen the safety of safety barrier.Meanwhile, in order to strengthen the nighttime visibility of guardrail, can reflecting strips (not shown) be set in the side of the second corrugated sheet steel 22 or gasbag 3.
Safety barrier with air bag of the present utility model, by being separately positioned on the air bag in upper buffer unit and lower buffer unit, has strengthened the anti-collision of safety barrier.And because it has very large elastic deformation space, therefore, in the time that vehicle bumps with it, not only can effectively absorb collision energy, but also can farthest prevent vehicle and personnel impaired.
Although the disclosed embodiment of the utility model as above, the embodiment that described content just adopts for the ease of understanding the utility model, not in order to limit the utility model.Technician under any the utility model in technical field; do not departing under the prerequisite of the disclosed spirit and scope of the utility model; can do any amendment and variation what implement in form and in details; but scope of patent protection of the present utility model, still must be as the criterion with the scope that appending claims was defined.
