Example Embodiment
[0040] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0041] like Figure 1 to Figure 5 As shown, a steel-ultra-high toughness concrete composite bridge deck based on steel truss connection, including the following components: steel deck roof 1, longitudinal stiffeners 2, lower chord reinforcement 3, upper chord reinforcement 4, web reinforcement 5, lower part Connecting steel bar 6, upper connecting steel bar 7, ultra-high toughness concrete 8.
[0042] like figure 1As shown, the single web bar 5 can be divided into a main wave part and a bottom arc part after being pressed and formed, and the two parts form 120° with each other in the transverse direction. Weld two lower chord steel bars 3 respectively at the positions where the bottom of the wave portion of the main body of the two web bars 5 is slightly higher than the arc portion, and weld the upper chord bars 4 between the vertices of the wavy porti...
