Arched beam connection structure of steel trussed beam arch bridge and construction method
The invention relates to an arched beam connection structure of a steel trussed beam arch bridge and a construction method. An upper reaming lug plate and lower reaming lug plates are welded to the upper side and the lower side of an arch rib through an upper lug plate force transmission plate and lower lug plate force transmission plates. The upper reaming lug plate is hinged to the lower reaming lug plates. Upper lug plate stiffening ribs and lower lug plate stiffening ribs are arranged on the two sides of the upper reaming lug plate and the two sides of the lower reaming lug plates, and all components are sealed in inlaying section plates. The inlaying section plates are welded to the connecting ends of the upper side and the lower side of the arch rib to form a complete arch rib. According to the construction method, the upper reaming lug plate, the lower reaming lug plates, a corresponding stiffening plate, the corresponding force transmission plates and the connecting end of the corresponding arch rib or joint plate are welded and connected in advance by a factory, the arch rib is assembled on a trussed beam on the field, after vertical rotation construction and closure of the arch rib are conducted, a hinge shaft and relevant hinge parts are sealed in the inlaying section plates on the field, and the inlaying section plates are welded and connected to the arch rib and the joint plate at the root of the arch rib. The arch beam connection structure is simple, force transmission is reliable, the size is small, materials are few, and the manufacturing price is low; the construction difficulty is low, safety of vertical rotation erecting of the arch rib is good, and the arched beam connection structure can be widely used for erecting of large-span steel trussed beam arch ribs, especially flexible arches.
