Described bridge anti-collision device composite material special structure is to be coated with for anticollision device, collision-prevention device metal surface and air or water body are isolated at the sheet metal of anticollision device, collision-prevention device or section bar external surface, and can play the composite layer that strengthens structure, anticorrosion, wear-resisting and crashworthiness effect, the thickness of composite layer is greater than 0.5 millimeter.
Described composite layer is the glass fiber reinforced plastics composite material layer.
The sheet metal of described anticollision device, collision-prevention device or section bar are that the cylinder-like shell body of the shell body of the shell body of flexible pier collision protection device or automatic positioning direction-guiding float pier collision proof device or floating round constant section anticollision device for bridge pier or float variable cross section are from the shell body of the anticollision device of pier that leads.
Advantage of the present utility model:
(1) the modular ratio steel of composite material special are little a lot, can make after ship collision occurs, and the boats and ships damage reduces greatly, by the destruction of anti-collision facility, reach the reduction ship and hit power, the navigation safety of protection bridge and boats and ships;
(2) at sheet metal, the section bar external surface of anticollision device, collision-prevention device, apply a kind of thicker composite material special layer, with anticollision device, collision-prevention device metal surface and air or water body isolation, greatly played the effect that strengthens structural anticorrosion, wear-resisting and crashworthiness;
(3) the utility model can be used on the bridge or anticollision device of pier of all metal constructions in water, the effect highly significant of anticorrosion, wear-resisting and crashworthiness.
The utility model is reasonable in design, and mechanics and chemical property are excellent more a lot of than original anticollision device, collision-prevention device structure, can be applied to the Anti-bumping protection of various forms bridge or bridge pier.When the anti-collision body of ship collision composite structure; after boats and ships bump against with the composite structure more much smaller than self steel modulus of elasticity; the crashproof damage of hull reduces greatly; the anti-collision facility life-span significantly improves; and can significantly reduce ship impact force, play the safety effects such as protection bridge, boats and ships.
