Description

A kind of highway guard plate

Technical field

The utility model belongs to guardrail field, more particularly to a kind of highway guard plate.

Background technology

At present, express-way guard-rail plates are the two root posts structures that by two panels waveform steel guard rail and between the two fixation is folded up Into two root posts are fixed and are installed between two panels waveform steel guard rail plate.When highway is normally operated, the guardrail is using plug column Can conveniently insert in the plug hole pre-set at opening, play isolation and protective action, while with highway outside on shield Hurdle band is mutually echoed, uniform, attractive in appearance supporting.

When vehicle is collided to which, as waveform steel guard rail plate plays the role of good Impact Resisting Capability and energy absorption, neither Easily smashed, while and can play a very good protection to vehicle and driver and conductor.When pavement maintenance or other reasons are needed When wanting and leading to, it is convenient to each group fence upright at opening is extracted and is removed, opened up passage, be easy to vehicle pass-through.

Highway guard plate generally adopts galvanized steel plain sheet now, has this generation problem to include：1. steel plate is oxidizable gets rusty, and 2. holds Easy scratch automobile, 3 production costs are high, and 4. lighter impulsive force easily causes guardrail deformation, 5. easily produce dirt in production process Dye.Therefore, need now a kind of more preferable highway guard plate of using effect badly.

Utility model content

Technical problem to be solved in the utility model, is for the defect and deficiency in aforementioned background art, there is provided one Plant impact property good, low cost, life-span length, the higher high intensity highway guard plate of security.

What the technical solution of the utility model was realized in：A kind of highway guard plate, including plate body, the plate body In cuboid-type, the plate body is made up of surface layer and core layer, and the number of plies of the surface layer and the core layer is one layer, described Surface layer is located on the core layer, and the plate body is additionally provided with anti-outer layer, and the number of plies of the anti-outer layer is two-layer, the anti-outer layer It is respectively arranged at the upside of the surface layer and the downside of the core layer.

As one preferred embodiment, the surface layer and the core layer be by extruder extrude after compression molding and Into.

As one preferred embodiment, the manufacture material of the surface layer is anti-ultraviolet CPP materials.

As one preferred embodiment, the manufacture material of the core layer is continuous fiber PP composite material and length TRPP.

As one preferred embodiment, the thickness of the surface layer is 3-6mm.

As one preferred embodiment, the thickness of the core layer is 2.5-3mm.

As one preferred embodiment, the thickness of the anti-outer layer is 0.2-0.5mm.

As one preferred embodiment, the thickness of the plate body is 5.9-10mm.

After employing above-mentioned technical proposal, the beneficial effects of the utility model are：Protective rail plate polypropylene on material is selected Composite, its intensity are high, and light weight, resistance to acids and bases are good, will not corrode, using uvioresistant CPP film, which can be made either to exist Under burning sun or can ensure which is not aging in severe cold, performance does not go down, safe and reliable.Three-decker, face is adopted in structure Layer material is ultraviolet aging resistance protective layer, and middle is long fibre enhanced polypropylene, after being impacted, absorbs impact energy, produces Deformation, as its structure is netted, can embody the impact property of the maximum of material, and outermost layer is 0/90 continuous lod poly- third Alkene layer, the intensity having are high, do not rupture after can absorbing whole energy, restore to the original state, greatly reduce the maintenance of product Expense.
