1 Introduction High-speed crash barrier is the main form of semi-steel guardrail, which is a corrugated steel fence panels to each other by stitching the main pillar supporting continuous structure. It uses the soil base, column, beam deformation to absorb impact energy and force out of control of the vehicle to change direction, to return to the normal direction of travel of the vehicle out of the road to prevent the outside, in order to protect the vehicle and passengers, to reduce the loss caused by the accident. Beam guardrail steel soft phase and, with a strong ability to absorb collision energy, has good sight inducing function, can be coordinated with the road alignment, beautiful appearance, can be used on small radius corners, damaged place easily replaced. Combination beam guardrail can be used on a narrow median strip. Category 2 Color: silver galvanized, spray green, white, blue and so on. Press waveform can be divided into three pairs of waveforms and waveform fence fence. Surface treatment is divided into two types according to spray galvanized guardrail and galvanized. Press to set the location can be divided into a roadside fence and the central median barrier. A crash can be divided by grade level and the S-Class. S-Class fence belongs enhanced for particularly dangerous sections of road side use, A grade for private roads. Common roadside beam guardrail crash level can be divided by B, A, SB, SA, SS five. 3 Specifications dual waveform guardrail: 4320mm × 310mm × 85mm × 3mm / 4mm three waveform guardrail: 4320mm × 506mm × 85mm × 3mm / 4mm double waveform guardrail column: 114mm / 140mm × 4.5mm × height; three wave-shaped fence Plate column: 114mm / 140mm × 4.5mm × height; column spacing: 2 m spacing and divided 4 m spacing; Connection: Connection column and the board have Fangzu block (abalone board supporting) and the bracket-style (ten Orifice) two. Dosage: Waveform guardrail standard segment column spacing 4 meters per kilometer by 250 panels, 250 columns, ends 2, column caps 250, discourage block 250, the connecting bolts M16 × 170/42 250 units, splice bolts M16 × 35 2000 sets. 4 Use features highways, one, two highways, provincial, county and rural roads area, large parking facilities and other safety crash. Guardrail bending an increase aesthetics, while increasing the steeplechase strength of both worlds; automatic production line extrusion, surface clean non-invasive, highly corrosion; Surface treatment maturity; corrosion, aging, sunscreen , high resistance, low temperature and other characteristics, outdoor life of up to 10-25 years in the environment; product concise structure, beautiful and practical, easy good transportation, installation, security properties, little actual terrain for the mountain, slope, bending zone adaptability particularly strong, moderate cost, suitable for large-scale use.
