Abstract
The utility model relates to a protective railing for a highway, which comprises upright posts made of an epoxy glass fiber material with wear and corrosion resistance and favorable elasticity. The protective railing for the highway, which is disclosed by the utility model, is made of the epoxy glass fiber material and replaces a steel protective railing; the performance of the protective railing accord with the JT/T281-2007 and JTGD81-2006 standards, thus the protective railing has the characteristic of interchange with the iron and steel protective railing; meanwhile, the protective railing has favorable mechanical strength and elasticity modulus; the tensile strength of the protective railing is three times that of A3 steel and can reach 1190Kg/cm<2>, the flexural strength is 900Kg/cm<2> and the elasticity modulus is 1.2x106MPa which is six times that of the A3 steel; the protective railing has a lighter weight and the specific gravity of 2 which is one fourth that of the steel railing; the protective railing has the advantages of convenience in mounting and transportation, favorable capabilities of corrosion, ageing and acidity resistance, low maintenance cost and favorable elasticity (the elasticity modulus is 1.2x106MPa); the phenomenon that the protective railing is damaged caused by plastic deformation because the protective railing is impacted is avoided, the service life of the protective railing of the highway is prolonged; and the protective railing can be widely applied to the field of protective equipment of the highway.
Description
Technical field
The utility model relates to a kind of railing, what be specifically related to is guard rail on a kind of speedway.
Background technology
Mostly present speedway guard rail is to adopt steel pipe to make, and galvanizing or mopping form on the steel body.Along with the high speed development of China's speedway, the steel using amount of freeway guardrail bar grows with each passing day.The output of steel of China keeps more than 100,000,000 tons always in recent years, the iron and steel resource anxiety in the whole nation.In order to keep the environment pollution in long-term sustainable development of mineral resources and the minimizing steel-making, must effectively control steel-making output; And existing steel speedway guard rail exists, and quality is heavy, defectives such as corrosion resistance is poor, application life is short, production link pollution, maintenance cost height.Therefore, existing speedway guard rail remains further to be improved.
The utility model content
At the deficiency that exists on the prior art, the utility model purpose is to be to provide a kind of light weight, anticorrosion, ageing-resistant, and the speedway guard rail of high mechanical properties and modulus of elasticity prolongs its application life.
To achieve these goals, the utility model is to realize by the following technical solutions:
The speedway guard rail comprises column, it is characterized in that, described column adopts is that the epoxy glass fiber material of wear-and corrosion-resistant, good springiness forms.
As preferably, also be provided with the wear-and corrosion-resistant layer on the described column, on described wear-and corrosion-resistant layer, be provided with fluorescence, reflector layer.
The beneficial effect that the utility model compared with prior art has is as follows:
1, light weight; The utility model adopts the epoxy glass fiber material to form, and its proportion is 2, is 1/4 of steel railing, and installation and transportation are convenient;
2, mechanical strength height.The utility model adopts the epoxy glass fiber material, and its tensile strength is more than 3 times of A3 steel, can reach 1190Kg/cm
2, flexural strength is 900 Kg/cm
2, modulus of elasticity is 1.2x10
6MPa is more than 6 times of A3 steel;
3, anticorrosion, ageing-resistant and acid resistance good has prolonged the application life of speedway guard rail, and maintenance cost is low;
4, good springiness; Because of adopting the epoxy glass fiber material to form its modulus of elasticity height, the damage of having avoided guard rail to cause because of plastic strain.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.
Referring to Fig. 1, speedway guard rail of the present utility model comprises column 1, and this column 1 is that the epoxy glass fiber material by wear-and corrosion-resistant, good springiness forms.
In the present embodiment, column adopts epoxy glass fiber to squeeze the trombone slide processing and fabricating and forms; Epoxy glass fiber is squeezed trombone slide be processed as the column 1 that meets the highway traffic safety design specifications fully, in column 1 upper end the wear-and corrosion-resistant layer is set, this wear-and corrosion-resistant layer 2 can adopt the epoxy glass fiber pipe box, is arranged on the upper end of column, increases scuff resistance.On described wear-and corrosion-resistant layer 2 surface, be provided with fluorescence, reflector layer.
In addition, column 1 external surface of present embodiment can be brushed the paint that meets the highway traffic safety design specifications, and is easy to use.
The utility model is that its performance meets the standard of JT/T281-2007 and JTGD81-2006 with the alternative steel guardrail of the steel material of the speedway guard rail of epoxy glass fiber material, so have the advantages that to exchange with the iron and steel guardrail; Have excellent mechanical intensity and chemical property simultaneously, tensile strength is more than 3 times of A3 steel, can reach 1190Kg/cm
2, flexural strength is 900 Kg/cm
2, modulus of elasticity is 1.2x10
6MPa is more than 6 times of A3 steel.
And light weight: the utility model adopts the epoxy glass fiber material to form, and its proportion is 2, is 1/4 of steel railing, and installation and transportation are convenient; Its anticorrosion, ageing-resistant and acid resistance is good, maintenance cost is low; Elasticity is good, and (modulus of elasticity is 1.2x10
6MPa), avoided guard rail to produce the damage that plastic strain causes, prolonged the application life of speedway guard rail because of being hit, but in the safeguard field of extensive use speedway.
More than show and declarative description basic 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 describes in the foregoing description and the manual just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof
