Abstract
A road guardrail comprises a yaw layer, a fixing layer and an energy-absorbing layer. The energy-absorbing layer is arranged between the yaw layer and the fixing layer, the yaw layer is composed of a W-beam guardrail, the fixing layer is of a concrete structure, and the energy-absorbing layer is made of elastic buffering materials. The road guardrail is simple in structure, has a yaw guide function of the W-beam guardrail and an anti-collision performance of a concrete guardrail, has the advantages of being wide in material source, low in cost and environmentally friendly, and meets the requirements of sustainable development.
Description
Technical field
The utility model belongs to a kind of highway barrier.
Background technology
Freeway guardrail as the at last barrier of speedway with the isolation boundary of external environment condition and protection vehicle, is being brought into play safely vital effect to guaranteeing vehicle driving.The guardrail that uses at present mostly is omnidistance guardrail; omnidistance Guardrail design is not simply, play a very good protection; on the contrary in some cases; this guardrail has become accident " arch-criminal " on the contrary; particularly in special locations such as steep cliff, viaduct, sky way, break turn, the turnings of wide-angle descending; take charge hits guardrail, and the accident of final car crash occurs repeatedly, some zone even be called as " dead location ".
Numerous and the most freeway guardrails of China's speedway mainly contain two kinds: waveform steel guard rail and reinforced concrete fence.The waveform steel guard rail is to use at present maximum freeway guardrails, but its protective capacities is limited, and in most cases guardrail can only hinder the high-speed motion of automobile to a certain extent, but its retarded acting is limited.And reinforced concrete fence can effectively stop the high-speed motion of automobile, but because the characteristics of its rigid protection, rider's safety is difficult to be protected.
A kind of highway barrier is arranged now, the spring that adopts is as elastic parts, install guardrail additional in the elastic parts both sides, but the impact that the car crass guardrail produced in the extremely short time is very huge, spring can not play cushioning effect because relatively dispersion being installed at all, if but use high strong spring, cost will become tens times raising so, and the expenditure of each high strong spring and the expense of each assembly are so that this guardrail cost is very high.
The utility model content
The purpose of this utility model be for the deficiencies in the prior art provide a kind of simple in structure, both had the guiding driftage effect of corrugated guardrail, the highway barrier of the crashworthiness of concrete guardrail is arranged again.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of highway barrier, comprise driftage layer, fixed bed and absorbing energy layer, described absorbing energy layer is arranged between described driftage layer and the fixed bed, and described driftage layer consists of for corrugated guardrail, described fixed bed is concrete structure, and described absorbing energy layer consists of for having flexible padded coaming.
Connect by the reinforcing bar elastic skeleton between described driftage layer, fixed bed and the absorbing energy layer.
Described absorbing energy layer is elastic caoutchouc.
Owing to adopting said structure, the utlity model has following advantage:
1. the structure driftage designs dissipation energy
Owing to having adopted corrugated guardrail as the driftage layer, therefore when bearing the automobile bump effect, structure driftage layer can a steer motor course, reduce impact momentum, as much as possible automobile is limited in the speedway, prevent the secondary injury after the personnel that ride go out highway, reduce simultaneously guardrail itself and be impacted.
2. the multi-buffer energy-absorbing effect is good
Adopt absorbing energy layer to carry out level 2 buffering, absorbing energy layer adopts elastomeric cushion material, therefore can produce larger elastic deformation, absorb a large amount of energy, and the fixed bed intensity that the steel concrete that supports driftage layer and absorbing energy layer consists of is high, guarantees that the guardrail overall structure plays the effect of three grades of bufferings in the time of good.Through the multi-buffer of this guardrail, reduce automobile impacting to by the impact damage of safeguard structure.
3. twice laid, environmental friendliness
Absorbing energy layer in the middle of this device can use junked tire etc., draws materials conveniently, has rationally utilized tire discarded in the life, have advantages of draw materials extensively, cost is low, environmental protection, meet the requirement of sustainable development.
In sum, guardrail adopts steel concrete and has the mode of flexible padded coaming coupling, the price of steel concrete is lower and be widely used, flexible material is optional to be the rubber of raw material in order to junked tire, also can adopt pitch, the cost of material is low for these, can well solve the problem of economy.
Description of drawings
Fig. 1 is structural representation of the present utility model;
The specific embodiment
Below in conjunction with accompanying drawing, further describe the specific embodiment of this patent.
As shown in Figure 1, a kind of highway barrier, comprise driftage layer 1, fixed bed 3 and absorbing energy layer 2, described absorbing energy layer 2 is arranged between described driftage layer 1 and the fixed bed 3, described driftage layer 1 consists of for corrugated guardrail, and described fixed bed 3 is concrete structure, and described absorbing energy layer 2 consists of for having flexible padded coaming, connect by the reinforcing bar elastic skeleton between described driftage layer 1, fixed bed 3 and the absorbing energy layer 2, described absorbing energy layer 2 is elastic caoutchouc.
The preparation method of above-mentioned highway barrier comprises the steps:
Embodiment: this device guardrail whole height is 950mm, it is the whole concrete guard bar structure form of 95cm thickness 165mm that outermost fixed bed 3 adopts height, absorbing energy layer 2 structures adopt the rubber-steel work of elastomeric material in the middle of the guardrail, innermost layer driftage layer 1 is the concrete smooth surface structure of maximum ga(u)ge 250mm minimum thickness 100mm, be evenly arranged 4 with reinforcing bar in the inboard concrete of driftage layer, the reinforcing bar axle center is from driftage layer outer surface 60mm, the reinforcing bar top is apart from guardrail upper surface 50mm, and it is that cage of reinforcement connects that the connection between three layers is fixed tentatively.
Claims (3)
1. a highway barrier is characterized in that, comprises driftage layer, fixed bed and absorbing energy layer, described absorbing energy layer is arranged between described driftage layer and the fixed bed, described driftage layer consists of for corrugated guardrail, and described fixed bed is concrete structure, and described absorbing energy layer consists of for having flexible padded coaming.
2. highway barrier according to claim 1 is characterized in that, connects by the reinforcing bar elastic skeleton between described driftage layer, fixed bed and the absorbing energy layer.
