The anti-collision three-stage energy absorption guard bar device is simple in structure, convenient to manufacture, and capable of effectively lowering the motor vehicle accident loss.
Description
Technical field
The utility model relates to speedway material, is specially a kind of three grades of energy-absorbing anti-collision guard bar devices.
Background technology
At present, highway anti-collision guardrail is on the basis of steel guardrail, and the Chen Xinyi in Taiwan has invented " road safety elastic reflective guardrail structure ", the patent No.: ZL 200820133226.9; The Li Qiang in continent has invented " elastic light reflection warning road safety guard fences ", the patent No.: ZL 200620137688.9.
Above-mentioned steel guardrail easily caves in, and color mostly is single grey, moulding dullness, and shock-absorbing effect is general, needs periodic maintenance, and difficulty of construction is large, and comprehensive cost is large; And steel are produced and will be consumed many energy, not environmental protection.And elastic reflecting warning guardrail, although adopt the macromolecular material such as ABS, PC, and be designed with buffering holder, reflection safety button and reflecting strips etc., material is more expensive, causes cost high; Production technology adopts injection moulding more, and cost of investment is high; In addition, when car collision guardrail, impact energy is mainly transmitted and is consumed by corrugated guardrail plate, still has potential safety hazard for large-tonnage vehicle (being greater than 10 tons).
Summary of the invention
The technical problem that the utility model solves is to provide a kind of three grades of energy-absorbing anti-collision guard bar devices, to solve the shortcoming in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of three grades of energy-absorbing anti-collision guard bar devices, comprise upright post cap, column, contiguous block, guardrail board, reflector layer, square steel pipe, obstruction block, described column top is provided with upright post cap, described guardrail board is to be bolted on contiguous block inside and outside two stacked adding, described reflector is positioned at the projection of outside guardrail board, between described contiguous block and obstruction block, be bolted square steel pipe crossbeam, can install one, also can two be set up in parallel above, described obstruction block is bolted on column upper end, and obstruction block is set up in parallel two up and down.
In the utility model, described guardrail board is wavy shaped configuration, described guardrail board falls in part and is bolted on contiguous block, described reflector is positioned at the projection of outside corrugated guardrail plate, the integrated approach of reflector can be reflectorized material and composite foundation material coextrusion mold, also can be fixedly mounted on guardrail substrate by reflector layer.
In the utility model, laterally adjacent two guardrail board are fixedly connected with by the bolt being positioned on guardrail board inclined side.
In the utility model, column, the design of rectangular steel tube crossbeam and corrugated guardrail, can realize resetting of post absorbing impact energy, and girder steel distortion energy-absorbing is realized the direction of guiding accident vehicle simultaneously, corrugated guardrail distortion energy-absorbing.
Beneficial effect: the utility model is simple in structure, easy to make, realize, column, three grades of girder steel and guardrail board absorb the energy producing while shock, can effectively reduce the loss of motor vehicle accident.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
As shown in the figure: 1, upright post cap; 2, contiguous block; 3, guardrail board; 4, reflector; 5, square steel pipe; 6, obstruction block; 7, column.
Detailed description of the invention
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, a kind of structural representation of three grades of energy-absorbing anti-collision guard bar devices, a kind of three grades of energy-absorbing anti-collision guard bar devices, comprise upright post cap 1, contiguous block 2, guardrail board 3, reflector 4, square steel pipe 5, obstruction block 6, column 7, described column 7 tops are provided with upright post cap 1, described guardrail board 3 is bolted on contiguous block 2, described reflector 4 is positioned at the projection of guardrail board 3, between described contiguous block 2 and obstruction block 6, be bolted square steel pipe 5, described obstruction block 6 is bolted on column 7 upper ends.
In the utility model, described guardrail board 3 is wavy shaped configuration, and described guardrail board 3 falls in part and is bolted on contiguous block 2, and described reflector 4 is integrated in the projection of guardrail board 3.
In the utility model, adjacent two guardrail board 3 are fixed by the bolt being positioned on guardrail board 3 inclined sides.
According to three grades of energy-absorbing anti-collision guard bar device assemblings of one as described in Figure, in the time there is motor vehicle accident, collision of motor-driven vehicles is to guard bar device, due to the waveform mechanism of guardrail board 3, the effectively energy of buffer motor-car, when the waveform mechanism of guardrail board 3 has absorbed after energy, square steel pipe 5 is the energy of absorption machine motor-car effectively.When square steel pipe 5 has absorbed after energy, obstruction block 6 and column 7 one reduce the energy of motor vehicle by changing displacement, the loss late of motor vehicle accident is reduced to minimum.
More than show and described general principle of the present utility model and principal character and advantage of the present utility model, the technician of the industry should understand, the utility model is not restricted to the described embodiments, that in above-described embodiment and manual, describes just illustrates principle of the present utility model, do not departing under the prerequisite of the utility model spirit and scope, the utility model also has various changes and modifications, these changes and improvements all fall within the scope of claimed the utility model, the claimed scope of the utility model is defined by appending claims and equivalent thereof.
