Profiled steel sheet-UHP (ultra high performance) fiber reinforced concrete composite bridge deck
A profiled steel sheet-UHP (ultra high performance) fiber reinforced concrete composite bridge deck comprises U-shaped profiled steel sheets, perforated steel sheets, vertical studs, horizontal reinforcements, longitudinal reinforcements and UHP fiber reinforced concrete. The vertical perforated steel sheets are longitudinally fixed in the centers of the grooves of the U-shaped profiled steel sheets. A plurality of fixed vertical stud rows are arranged on raised portions of the U-shaped profiled steel sheets. The horizontal reinforcements penetrate connecting holes in the perforated steel sheets and are welded with the upper ends of the vertical studs. The longitudinal reinforcements are perpendicular to the horizontal reinforcements and fixedly connected with joints of the horizontal reinforcements and the vertical studs. The UHP fiber reinforced concrete is poured in the U-shaped profiled steel sheets to cover the perforated steel sheets, the vertical studs and the horizontal and the longitudinal reinforcements. According to the arrangement, the adhesion performance of the interfaces of the profiled steel sheets and the UHP fiber reinforced concrete is improved, and mechanical advantages of the profiled steel sheets and the UHP fiber reinforced concrete are fully played. The profiled steel sheet-UHP fiber reinforced concrete composite bridge deck dead is low in weight, high in bearing capacity, excellent in anti-fatigue performance, available in industrialized production and on-field assemble, higher in bridge deck building and changing speed and the like.
