Description
Technical field
The utility model relates to a kind of crash barrier for roads.
Background technology
At present, constantly perfect along with city and rural road, road equipment also increases thereupon, and anticollision barrier is a kind of comparatively common road equipment, is used for protection and limit for width on both sides of the road, is also applicable to cut apart two-way lane simultaneously.
Anticollision barrier of the prior art is mostly the form of support bar and crash bar combination, support bar is fixed on support bar by the mode of screw or welding, but the Crashworthy plate in this technology is a simple metal sheet, after processing by bending, form a corrugated stress surface, its crashworthiness ability of the anticollision barrier of this structure is poor, simultaneously after absorbability, born power is directly passed to support bar, directly caused the bending of anticollision barrier, the vehicle that causes the accident is gone out the security incident of anticollision barrier.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of crash barrier for roads, and this device has stronger impact resistance, when being subject to Vehicular impact, can avoid preferably bending, avoids vehicle to go out road, safeguards the safety of driver and vehicle.
For addressing the above problem, the utility model adopts following technical scheme:
A kind of crash barrier for roads, the support bar that comprises some parallel arrangements, and setting is connected to the crash bar between two adjacent support bars, described crash bar comprises crashproof base bar and stressed plate, described crashproof base masthead portion 90-degree bent, the recess that support bar is used is held in curved one of rear formation, between described crashproof base bar outside and support bar, be fastened with the first screw, the screw terminal of described the first screw passes through and is inserted in recess, one end that described crashproof base bar deviates from described support bar has the energy-absorption box of a circular arc, between described stressed plate and crashproof base bar, be fastened with bolt, described stressed plate has the arc sections of two evaginations, after described stressed plate and the combination of crashproof base bar, forming one is distributed on described energy-absorption box, downside, and the first energy-absorption box of coated described energy-absorption box.
As preferred technical scheme, the bottom of described support bar is provided with bracket, between the lateral wall of described support bar and described bracket, be fastened with the second screw, described the second screw annular is provided with more than four, the lower end of described bracket is welded with the plate of building of building use, and on described bracket, annular is provided with four above installing holes.
As preferred technical scheme, described in to build plate be cross, on its four orthogonal plate faces, be provided with pouring hole, described in described pouring hole runs through, build plate.
The beneficial effects of the utility model are: this device is when being subject to impacting, by the first energy-absorption box and the second energy-absorption box, can reduce preferably the injury that impact force causes support bar, and when this device is subject to less impact, only stressed plate need to be disassembled and carry out simplified overhauling, reduced the regular maintenance cost of road equipment, the application of this device can strengthen road safety guarantee, improve driver's chances of survival, reducing car damages, and this apparatus structure is comparatively simple, manufacture more for convenience, and cost is comparatively cheap, is applicable to promoting the use of.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
