Described bridge plate is made up of bridge floor steel plate, tack coat, the layer of mating formation from bottom to top successively.
The access bridge at described overline bridge master bridge two ends and main bridge form H shape, and access bridge itself is S-shaped; The end of access bridge is provided with bi-directional escalator and vertical lift.
Described suspension rod only has the perpendicular suspension rod of rigidity, and its upper end is connected with bridge crossing steel case beam diaphragm by the unidirectional hinge that can freely rotate in the horizontal direction, and the lower end of erecting suspension rod is affixed by joint and main longitudinal grider and crossbeam.
Described suspension rod combines with the oblique suspension rod of rigidity for flexible perpendicular suspension rod, and upper end perpendicular, tiltedly suspension rod is connected with bridge crossing steel case beam diaphragm by the unidirectional hinge that can freely rotate in the horizontal direction, erects, the lower end of oblique suspension rod is affixed by joint and main longitudinal grider and crossbeam.
Described main longitudinal grider is seamless square steel pipe, and crossbeam is a square steel pipe, and perpendicular suspension rod is the seamless circular steel pipe.
The invention has the beneficial effects as follows: this overline bridge is main load-supporting part with bridge crossing, bearing pedestrian load and overline bridge dead load, because not load-bearing of overline bridge bridge plate itself, to make the overline bridge lightness, not only avoid too much lower support structure, help traffic above-ground tissue and underground utilities setting, and the deadweight and the steel using amount of pedestrian bridge have been reduced, attenuate the overline bridge structural thickness, reduced the control point absolute altitude of bridge crossing under the conventional design, reduced the cost of whole engineering; Simultaneously make that also whole overline bridge permeability is good, span is big, and is merrily and lightheartedly attractive in appearance.
