Abstract
The utility model discloses an expressway guardrail which comprises guardrail plates and stand columns. The guardrail plates are connected with the stand columns. The expressway guardrail is characterized in that the stand columns are of an H-shaped steel structure, an erosion resistant coating is arranged on the surface of each H-shaped steel stand column, the bottom portion of each H-shaped steel stand column is provided with a carbon steel connecting flange, a carbon steel reinforcing rib plate is welded between each stand column and each connecting flange, a cushion block is arranged between each guardrail plate and each stand column, each guardrail plate is of a wave-shaped structure, the guardrail plates and the stand columns are connected through high-strength bolts, each guardrail plate adopts a wave shape with two waves or three waves, the thickness of each guardrail plate is 8 millimeters to 20 millimeters, and the guardrail plates and the cushion blocks are made from ultra high molecular weight polyethylene materials. The expressway guardrail has the advantages of being corrosion-resistant, impact-resistant, anti-aging, self-lubricating, high in environment protection, light in weight, convenient to construct and capable of reducing occurrence of secondary injury accidents, reducing the number of injuries and deaths, reducing manual maintenance cost and environment pollution caused by painting and reducing guardrail cleaning cost.
Description
Technical field
The utility model relates to highway safety guard technology field, relates in particular to a kind of freeway guardrail.
Background technology
The fence upright of the speedway of prior art is connected with ground, the problem that exists is fixing unreliable, easily loosening, easily burn into is short application life in the bottom, and guardrail adopts the steel guardrail plate usually, the problem that the steel guardrail plate exists is: intensity is not low, and is corrosion-resistant, the life-span is short, and easily damage, replacing and rehabilitation cost are high, after surperficial mopping, cause environment pollution and easily aging, have the defective that safety factor is low, potential safety hazard is large; The guardrail board cost that adopts composite material to make is high; Adopt and the intensity of glass fiber reinforced plastic and common plastics guardrail board is low, easily aging, safety factor is low, therefore exists huge potential safety hazard large.
Summary of the invention
The purpose of this utility model is exactly the problems referred to above and the deficiency that exists in order to solve prior art; A kind of freeway guardrail is provided; Have reliable in structure, intensity is high, and is fixing reliable, and corrosion-resistant, shock-resistant, anti-aging, self-lubricating, high-environmental, lightweight, the easily advantage of constructing can reduce the secondary injury odds, reduce the generation of secondary injury accident, reduce casualties quantity; Guardrail board and cushion block need not mopping, reduce because manual maintenance cost and the environment pollution that mopping brings reduces the guardrail cleaning up cost.
To achieve these goals, the utility model adopts following technical scheme:
A kind of freeway guardrail, comprise guardrail board, column, guardrail board is connected with column, described column is the H formed steel construction, and H shaped steel column surface is provided with anticorrosive coat, and H shaped steel column bottom is provided with the carbon steel adpting flange, be welded with carbon steel between column and the adpting flange and strengthen gusset, be provided with cushion block between described guardrail board and the column, guardrail board is waveform configuration, and described guardrail board is connected by high-strength bolt with column.
Described guardrail board and cushion block adopt superhigh molecular weight polyethylene material.
Described guardrail board adopts two ripples or three waveforms, and the thickness of guardrail board is 8-20mm.
The utility model operating principle: the utility model comprises guardrail board, column, guardrail board is connected with column, described column is the H formed steel construction, H shaped steel column surface is provided with anticorrosive coat, H shaped steel column bottom is provided with the carbon steel adpting flange, is welded with carbon steel between column and the adpting flange and strengthens gusset, is provided with cushion block between described guardrail board and the column, guardrail board is waveform configuration, and described guardrail board is connected by high-strength bolt with column.Column is fixed on the guardrail foundation by the carbon steel adpting flange, and is fixed, prevent from arbitrarily being moved and stealing; Carbon steel is strengthened gusset and is welded between column and the flange, and the bonding strength, the column that have increased column and flange play reinforcement effect; The ultra-high molecular weight polyethylene cushion block places between ultra-high molecular weight polyethylene guardrail board and the H shaped steel column, be connected firmly and can impact power play cushioning effect, guardrail board and cushion block are fixed on the H shaped steel column reliably by high-strength bolt, it is the superhigh molecular weight polyethylene material of 8-20mm that guardrail board adopts thickness, adopt two ripples or three waveform structures can alleviate greatly impact force, cost is low, can satisfy the working strength requirement again, guardrail board and cushion block need not mopping simultaneously, have corrosion-resistant, shock-resistant, anti-aging, self-lubricating, high-environmental, lightweight, the easily advantage of constructing, reduce the secondary injury odds, reduce the generation of secondary injury accident, reduce casualties quantity, reduce because manual maintenance cost and the environment pollution that mopping brings reduces the guardrail cleaning up cost.

Fig. 2 is the left view of Fig. 1;
Wherein, 1, column, 2, guardrail board, 3, cushion block, 4, bolt, 5, strengthen gusset, 6, adpting flange.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
A kind of freeway guardrail, in conjunction with Fig. 1, Fig. 2 comprises guardrail board 2, column 1, guardrail board 2 is connected with column 1, described column 1 is the H formed steel construction, and H shaped steel column surface is provided with anticorrosive coat, and H shaped steel column bottom is provided with carbon steel adpting flange 6, be welded with carbon steel between column 1 and the adpting flange 6 and strengthen gusset 5, be provided with cushion block 3 between described guardrail board 2 and the column 1, guardrail board 2 is waveform configuration, and described guardrail board 2 is connected by high-strength bolt 4 with column 1.
Described guardrail board 2 is superhigh molecular weight polyethylene material with cushion block 3.
Described guardrail board 2 adopts two ripples or three waveforms, and the thickness of guardrail board 2 is 8-20mm.
Be fixed on the guardrail foundation by carbon steel adpting flange 6, carbon steel is strengthened gusset 5 and is welded between column 1 and the flange 6, and column 1 plays reinforcement effect; Ultra-high molecular weight polyethylene cushion block 3 places between ultra-high molecular weight polyethylene guardrail board 2 and the H shaped steel column 1, and impact power plays cushioning effect; Ultra-high molecular weight polyethylene guardrail board 2 and ultra-high molecular weight polyethylene cushion block 3 tightly are fixed on the H shaped steel column 1 by high strength connecting bolt 4; The ultra-high molecular weight polyethylene of ultra-high molecular weight polyethylene guardrail board 2 and two ripples that adopt or three waveform structures can be alleviated impact force greatly.
Although above-mentionedly by reference to the accompanying drawings the specific embodiment of utility model is described; but be not the restriction to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection domain of the present utility model.
