Long-span assembly type road steel truss bridge
The invention discloses a long-span assembly type road steel truss bridge which can be erected across the 90m span. The long-span assembly type road steel truss bridge comprises a left truss and a right truss. Beams are arranged between the left truss and the right truss. Wind resistance pull rods and a vertical wind structure are arranged between every two adjacent beams. A bridge face board is arranged on the beams. Reinforcing chord members are arranged on upper chords and lower chords of the trusses. The long-span assembly type road steel truss bridge is characterized in that the distance between pin holes in the height direction of each truss ranges from 2400 mm to 2800 mm, and the distance between pin holes in the length direction of each truss ranges from 5800 mm to 6000 mm; the chord member sections of upper chord members, lower chord members, vertical rods, inclined rods and the reinforcing chord members of the trusses are square pipes or rectangular pipes, and the problems that an existing assembly type steel bridge is small in span and large in deflection are solved.
