Abstract

The invention belongs to the technical field of track traffic and discloses a suspended single-track large-span track beam system. The suspended single-track large-span track beam system comprises a main beam and steel box track beams, wherein a longitudinal direction of the main beam extends along a front-rear direction; the main beam comprises a top beam and two side boxes; the two side boxes are parallel to each other and respectively arranged at the left and right ends at the bottom of the top beam; the left and right side boxes respectively penetrate through bridge towers on correspondingsides and are nested on the bridge towers on the corresponding sides, so that fixed connection between the bridge towers and the main beam is realized; in addition, each of the side boxes is respectively connected with the bridge tower on the corresponding side by virtue of a stay cable; two steel box track beams are arranged; a longitudinal direction of each of the steel box track beams extendsalong the front-rear direction; each of the steel box track beams is suspended on the top beam; and the two steel box track beams are positioned between the two side boxes. The suspended single-tracklarge-span track beam system disclosed by the invention has the characteristics of being simple in structure and clear in stress, and the requirements on structural safety and service function in thesuspended single-track large-span track beam are met.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and more specifically relates to a suspended monorail long-span rail beam system. Background technique [0002] Suspension monorail transportation is a new technology of rail transportation. Not only has no technical specifications to follow for suspension rail transportation, but also there are few reference materials. Suspended rail transportation has a long history in foreign developed countries. The monorail is dominated by conventional spans (span ≤ 30m). At present, there are only two test lines in my country that also adopt the conventional span layout, so the suspended monorail large-span track beam system is an imminent task for the suspended monorail. [0003] The domestic test line adopts the same small-section steel box track beam structure with floor openings abroad. The steel track beam has problems such as small width-span ratio, easy buckling, small bearing capacity, large d...
