Abstract
Description
Technical field
The utility model relates to a kind of highway barrier reconstruction structure form, and particularly a kind of corrugated beam barrier forms of modification is used for improving as security protection facility on the highway measure of protective capacities.
Background technology
Etesian traffic accident is all in rapid increase, and especially highway accident more very.Wherein because the accident of Vehicular impact guardrails of both sides of highway accounts for the significant proportion of annual accident.Expressway speed is fast, in case vehicle is out of hand, be easy to take place serious accident, though all be provided with guardrail on the highway at present, can play certain protective action, but the protective capacities of guardrail is lower, Vehicular impact is behind guardrail, seriously cause occupant's injures and deaths after gently then clashing into guardrail, heavy then vehicle passes guardrail, or pour the subtend track or directly pour hazardous location such as trackside gutter, casualty rate and economic loss are bigger, so the high guardrail of exploitation protective capacities has become the society need of traffic safety facilities research.
Simultaneously, along with China's rapid economy development, the speedway career development is rapid, continuous growth along with the operation amount, serious damage, phenomenon such as aging have appearred in many express highway pavements, press for to carry out cover and handle, simultaneously, because the growth of the traffic volume, the part speedway need be widened processing.No matter be cover or widen etc., utilizing again of original safety device become new research topic, if lay guardrail again, then expense is higher, and original material is caused very big waste.
If study a kind of guardrail form, can have suitable protective capacities, can make full use of the former guardrail of haveing been friends in the past again, can have outward appearance preferably again simultaneously, then can reduce safety device significantly cost is set.
The utility model content
The purpose of this utility model provides a kind of corrugated beam barrier reconstruction structure, and this guardrail can make full use of old guardrail, and cost is lower, and the protection energy of 93kJ can be provided simultaneously, satisfies degree of protection A and the Am level requirement of former China to corrugated beam barrier.
For realizing above-mentioned target, the utility model adopts following technical scheme: guardrail of the present utility model comprises column and guardrail board, deters member and connecting elements; Its central post comprises sheathed internal layer column and outer column, and guardrail board comprises inboard guardrail board and the outside guardrail board that make-up is provided with; Inside and outside side rail plate is connected with outer column by deterring member and connecting elements.
Above-mentioned described guardrail board comprises inboard guardrail board and the outside guardrail board that make-up is provided with, and divides inside and outside two-layer butt joint to constitute the figure of eight.
Described internal layer column can be the original column before transformation on the highway, can certainly use and newly beat column.
The described member that deters can be carriage, obstruction block or their combinations.
Used guardrail board can be corrugated sheet or three ripple plates.
Guardrail of the present utility model, because the guardrail board and the sheathed column of ectonexine that have adopted inside and outside double-deck make-up to be provided with, thereby the combination that can utilize old guardrail board reaches higher requirement of shelter, can utilize the column of original setting to improve the intensity of column as the internal layer column simultaneously.Not only can make full use of original guardrail facility, improve the guardrail protective capacities simultaneously greatly.When vehicle collision behind guardrail, the inside and outside two-layer guardrail board of guardrail can both play protective action, can effectively protect collision energy at 93kJ with interior vehicle.The utility model structure design is simple, rationally, construct simple and easy, with low cost, good looking appearance, reality is a kind of economy, guard bar structure form attractive in appearance.
Description of drawings
Fig. 1 is the section structure schematic diagram of a kind of embodiment of the utility model.
The specific embodiment
Now the utility model is described in further detail in conjunction with the accompanying drawings.
Embodiment 1:
As shown in Figure 1, guardrail of the present utility model by guardrail board, column, deter member and connecting elements is formed.Wherein guardrail board is formed by outside corrugated sheet 1 and the 3 make-up settings of outside corrugated sheet, forms the structure of one " 8 " font.Column is that wherein internal layer column 6 can directly use original fence upright by outer column 5 and internal layer column 6 sheathed forming.Connecting elements is then used bolt for connecting, and deters member and uses carrier structure.The intermediate recess position that make-up is arranged to the guardrail board of " 8 " font is provided with connecting bolt 2, by this connecting bolt 2 with deter carriage 4 and be connected, deter carriage 4 and be fixed together with outer column 5.Outer column 5 then links together by connecting bolt 7 and internal layer column 6, and the lower end of outer column 5 is embedded in the layer of concrete 8, and layer of concrete 8 can be along the horizontal concrete belt of guardrail.
Certainly connecting elements can also be other connected mode, deters member and also can be the obstruction block structure or other deters structure.
And guardrail board make-up forms when adopting three ripple plates can not be " 8 " font structure, but the similar structures of alternative many rings.
Internal layer column 6 can adopt column existing or newly-increased on the highway, and the column spacing is 4m, and guardrail board then can directly use the old guardrail board or the new and old guardrail board of no gross distortion, corrosion etc. to be used in combination.The protection energy of this guardrail can reach 93kJ.
