Assembled-type steel bridge deck with prefabricated light-thin wear-proof anti-skid layer

Abstract

The invention discloses a steel bridge deck with a prefabricated light-thin wear-proof anti-skid layer, wherein the steel bridge deck with the light-thin wear-proof anti-skid layer is prefabricated in a factory and only requires combination and assembly on site. The steel bridge deck comprises an orthotropic steel bridge deck and the light-thin wear-proof anti-skid layer disposed on the steel bridge deck, wherein the light-thin wear-proof anti-skid layer is composed of an reactive polymer adhesive and single-grading wear-proof aggregates; the steel bridge deck is coated by the reactive polymer adhesive to form a waterproof adhesion layer; and the single-grading aggregates are uniformly spread on the adhesion layer to form a course wear-proof layer. The total thickness of the wear-proof anti-skid layer is 6-10 mm; a dynamic friction value exceeds 70; the weight is light, so the bridge weight is only increased slightly; resistance to water and corrosion is excellent; and resistance to wear and skidding is outstanding. The steel bridge deck disclosed by the invention has the advantages that advantages of high polymer material technologies and factory pre-pavement technologies are applied; defects of weak resistance of the steel bridge deck to wear, skidding and corrosion are solved; and safety and comfort are improved in travelling.

Description

technical field [0001] The invention relates to an assembled steel bridge deck, in particular to a steel bridge deck with a prefabricated light and thin wear-resistant and anti-skid layer. Background technique [0002] At present, domestic prefabricated highway steel bridge decks generally use patterned steel plates or anti-skid strips to improve the anti-skid ability of the bridge deck, but the steel is easy to corrode and has poor wear resistance. With the passage of service time and the increase in the number of vehicles, the surface protection layer (hot-dip galvanized layer or anti-corrosion paint coating) of the checkered steel plate and the bridge deck with anti-skid strips will gradually be worn away, and the steel bridge deck is easily exposed to the atmosphere. It is corroded, and the texture of the checkered steel plate will be gradually worn and the anti-skid ability of the bridge deck will be reduced, which will affect the driving safety. In addition, the steel...

Problems solved by technology

[0002] At present, domestic fabricated highway steel bridge decks generally use patterned steel plates or anti-skid strips to improve the anti-skid ability of the bridge deck, but the steel is easy to corrode and has poor wear resistance.

With the passage of service time and the increase in the number of vehicles, the surface protection layer (hot-dip galvanized layer or anti-corrosion paint coating) of the checkered steel plate and the bridge deck with anti-skid strips will gradually be worn away, and the steel bridge deck is exposed to the atmosphere. It is corroded, and the texture of the checkered steel plate will be gradually worn away, and the anti-skid ability of the bridge deck will be reduced, which will affect the driving safety

In addition, the steel bridge deck with anti-skid strips has serious bumps and noises during driving, and the driving comfort is not good.
