Problems solved by technology

However, the height of the shear key in the conventional shear structure is large, resulting in an increase in the thickness of the steel bridge pavement layer, which causes an increase in the dead load of the bridge deck and reduces the economy.
At the same time, the construction of the shear key needs to be equipped with special construction equipment and personnel, and the process is cumbersome, resulting in a decrease in the construction efficiency of the steel bridge deck pavement
In view of the problems existing in the above shear structure, at present, cable-stayed steel mesh has

Abstract

Provided is a steel bridge deck pavement structure with reinforced construction. The steel bridge deck pavement structure is jointly composed of a prefabricated reinforced steel plate (1), an anticorrosion layer (2), a waterproof layer (3), a lower surface layer (4), a fiber grid (5) and an upper surface layer (6) from bottom to top, and is characterized in that the top surface of the prefabricated reinforced steel plate (1) is provided with the reinforced construction, the fiber grid (5) is composed of longitudinal grid ribs (51) and transverse grid ribs (52) in a mutual interlaced mode, theinteriors of the lower surface layer (4) and the upper surface layer (6) are mixed with reinforced short fibers, and the fiber grid (5) is poured between the lower surface layer (4) and the upper surface layer (6) or into the upper surface layer (6), and achieves common working with the lower surface layer (4) and the upper surface layer (6) through surface construction. The steel bridge deck pavement structure with the reinforced construction has a good interlayer bonding performance, and can effectively prevent the risk of interlayer cracking and pavement layer fatigue cracking, meanwhile, through a novel prefabricated reinforced steel plate mode, the construction technology is simplified, the construction efficiency is greatly improved, the production installment cost is saved, the building cost of projects is reduced, and the normal use and durability needs of a bridge structure can be met.
