Name] [Introduction] waveform waveform fence fence fence is also known as corrugated sheets, galvanized sheet fence, guardrail, W zinc steel fence, road barrier. Its English name is corrugated beam barrier is currently the most widely used at home and abroad Bridge security fence. Waveform fence belongs to the cold-rolled, semi-steel fence; the general location and the collision by setting rating to classify. By setting location can be divided into roadside guardrail and the guardrail median strip; press collision level can be divided into A and S-Class; S-class fence belongs enhanced for particularly dangerous sections of road side use; A grade for private beam guardrail highway guardrail is the main form, and it is a corrugated steel fence panels to each other by stitching continuous main columns supporting the structure. [Specification] (L * W * wave height * thickness) double beam guardrail plate length 4320mm, width 310mm, wave height 85mm, thickness: 3mm, 4mm; three beam guardrail plate length 4320 mm, width 506mm, wave height 85mm, thickness : 4mm; [Material] Q235 [amount] 1 project, a ton double-wave guardrail can shop: 80 m 3MM thick, 61 meters thick 4MM, theoretical weight: 3mm thick is 49.16kg, 4mm thick as 65.44kg ; 3MM per kilometer thick heavy 12.3 tons per kilometer 4MM thick heavy 16.388 tons. 2, a ton of three-wave guardrail can spread: 39.2 m 4MM thick. Theoretical Weight: 102kg, with square tube column 130 * 130. 4MM per kilometer thick heavy 25.5 tons [column] Round column: Specification Φ114, Φ140mm length is generally 1 m, 1.2 m, 1.5 m, 1.8 m, 1.85 m, 1.95 m, 2 m, 2.15 m thickness according to claim 4 / 4.5MM; theoretical weight:. Φ114 of 12.15kg / m, Φ140mm of 15.04kg / m waveform guardrail most commonly used models: Gr-A-4E. Every 1000 meters Gr-A-4E amount guardrail members are: wave plate 250. Column 250, column spacing 4 meters. Column cap 250. Fangzu block (or bracket) 250, the terminal 2. Bolt M16 * 170,250 sets. M16 * 42,250 sets. M16 * 35,2000 units. Square column: the length 130mm, thickness 6mm, length 2540mm. [Column] cap thickness of 2 / 3mm, pitch 100 / 150mm, diameter 114 / 140mm. [Fangzu block] 196 * 178 * 200mm, thicknesses 3/4 / 4.25 / 4.5mm. [Bracket] length 300mm, width 70mm, thickness of sub-4mm / 4.5mm. [Bolt] M16 * 170 / M16 * 150 / M16 * 50 / M16 * 42 / M16 * 35 links [link] column and wave board: Fangzu block / bracket column and floor are linked: embedded / Falun plate General column spacing is divided into 2 m spacing and 4 m spacing; [Surface Treatment] hot dip galvanizing, cold galvanizing + spray, hot-dip zinc + spray. [Principle] function when receiving external force, through fence panels and pillars deform to absorb the impact force, the protection of pedestrians and vehicles. [Application] is currently widely applied in domestic highways, primary, secondary roads, provincial and county roads and scenic, rural roads. [Role] security, beautify the environment. [System principle] 1, beam guardrail is the main form of semi-steel guardrail, which is a corrugated steel fence panels to each other by stitching columns supporting a continuous structure. 2, which uses soil base, column, beam deformation to absorb impact energy, and forcing runaway 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 and reduce the losses caused by the accident. 3, 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 . Features: a good impact resistance, low cost, long life, high security, environmental protection, etc. Material: high quality steel embalmed Usage: mainly used for road lanes isolation protection waveform utility model relates to a highway guardrail central median opening with combination wave plate movable steel fence, the fence between the two pieces of the corrugated steel fence panels and two fixed clip to put two columns constituted two columns fixed interposed between two sheets of corrugated steel fence between the plates. When the road normal operation, the use of plug fence post can be easily inserted into the opening of the pre-set plug hole, played the role of isolation and protection, while outside on the road and fence with echoes, uniform, beautiful package. When their vehicle collision, since the corrugated steel fence boards have good crashworthiness and energy absorption effect, not easily been destroyed, while at the same vehicles and Division staff play a very good protection.
