Abstract
The utility model relates to a highway guardrail, which comprises a beam plate with a wavy cross section, wherein connecting bolt holes and splicing bolt holes are evenly arranged on the beam plate. The highway guardrail is characterized in that the wavy beam plate comprises a keel layer and wear-resistant, corrosion-resistant layers arranged on both sides, and the keel layer consists of a framework layer formed by a plurality of strands of straightly arranged continuous fiber bundles and a crossed netty reinforcing layer. The utility model has the following advantages: stretched composite material which is made from adapted modified hybrid resin under variable-frequency temperature control in a mold cavity is adopted to substitute the steel guardrail, and the performance of the highway guardrail can measure up to the standards of JT/T281-2007 and JTGD81-2006, so the highway guardrail and the steel guardrail can be exchanged; and meanwhile, the highway guardrail, which has the advantages of high strength, deformation resistance, little friction, wear resistance, shock absorption, noise reduction, corrosion resistance and fluorescent and reflective effects, can greatly reduce the loss of lives and properties, effectively protect the safety of vehicles, drivers and passengers and reduce the magnitude of disasters and secondary disasters.
Description
Technical field
The utility model belongs to freeway guardrail, relates in particular to a kind of freeway guardrail that adopts nonmetals to substitute steel plate.
Background technology
Freeway guardrail is to adopt the steel plate punching press to make always.Along with the high speed development of China's speedway, the steel using amount of freeway guardrail 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.Therefore at the every profession and trade use steel that should practice every conceivable frugality, rationally utilize iron and steel resource, select for use other materials to substitute steel simultaneously.
The utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and a kind of freeway guardrail is provided, and adopts adapted modification hybrid resin to control through die cavity frequency conversion temperature and produces the alternative iron and steel guardrail of elastomeric compositions, has the advantages that to exchange with the iron and steel guardrail; Have good high strength, not yielding, wear-resisting, shock-absorbing, de-noising, corrosion-resistant and fluorescence and reflective effect simultaneously.
The utility model for achieving the above object, by the following technical solutions: a kind of freeway guardrail, comprise that cross section is the beam slab of waveform, be laid with on the beam slab and connect screw and splicing screw, it is characterized in that: described waveform beam slab is made up of keel layer and the wear-and corrosion-resistant layer of being located at the two sides, and described keel layer is made up of the casing play of in line some strands of continuous tows and the netted enhancement layer that intersects anyhow.
The wear-and corrosion-resistant layer on described waveform beam slab surface is provided with fluorescence, reflector layer.
The fixedly connected buffer in the described waveform beam slab outside, described buffer are that the cross section is oval or fan-shaped buffer body, and fan-shaped buffer body two side is made as the waveform damping wall.
Described buffer is made up of keel layer and the wear-and corrosion-resistant layer of being located at the two sides, and described keel layer is made up of the casing play of in line some strands of continuous tows and the netted enhancement layer that intersects anyhow, and the wear-and corrosion-resistant layer is provided with fluorescence, reflector layer.
The utility model beneficial effect: adopt adapted modification hybrid resin to control and produce the alternative iron and steel guardrail of elastomeric compositions through die cavity frequency conversion temperature, its performance meets the standard of JT/T281-2007 and JTGD81-2006, so have the advantages that to exchange with the iron and steel guardrail; Have good high strength, not yielding, wear-resisting, shock-absorbing, de-noising, corrosion-resistant and fluorescence and reflective effect simultaneously, can reduce life and property loss greatly, effectively protect motor vehicle and driver and crew's safety, reduce the degree of disaster and secondary disaster.
