Fill insulant material's steel road deceleration strip

The utility model belongs to a road equipment technical field, strong but toughness not enough in order to solve current cast steel (iron) deceleration strip rigidity, and the bearing capacity is little, and is easy to be broken, and problem that life is short provides a fill insulant material's steel road deceleration strip. Including the bottom plate, welding arc -shaped roof in bottom plate top forms between bottom plate and the arc -shaped roof and fills the chamber, establishes the square mouth that fills in the middle of the bottom plate, and the bolt hole is laid at the interval on the bottom plate, arc -shaped roof longitudinal separation welding crescent moon backing sheet, arc -shaped roof is last to be corresponded the bottom plate bolt hole site and puts to the arc -shaped roof inboard cutting into semicircular notch, vertical welding and the inclosed horse's hoof arc piece of bottom plate around the breach, the polyurethane insulation material is filled to packing intracavity between bottom plate and the arc -shaped roof. Have the toughness of the intensity iron of steel, the wheel can't cause destruction, and insulation material plays and blocks that the deceleration strip absorbs the thermal effect of the sun, reduces sunlight the toasting of road surface under to the deceleration strip. Can adapt to cement road surface and bituminous paving, bearing capacity is not less than 200 tons.
