Problems solved by technology

The concrete of the traditional corrugated steel web bottom plate is easy to crack in the positive bending moment area, and the open-hole steel plate connectors are often used for the bottom plate and the web plate, which are easy to fall off. In the suspended monorail system, the corrugated steel web box-type composite track beam must be solved. There are problems in the traditional prestressed concrete box girder bridge with corrugated steel web, and the problem of corrugated steel web as the guide surface needs to be solved

Abstract

The invention belongs to the technical field of suspension type single track traffic, and discloses a suspension type combined box type prestress track beam system with a bottom plate being open. Thesuspension type combined box type prestress track beam system comprises a concrete top plate, two single track train travelling tracks and a post-tensioning method external prestressed steel beam structure. Each single track train travelling track is arranged on the bottom face of the concrete top plate, and comprises an upper flange, a wave-shaped steel web, the bottom plate, a concrete liner andpre-tensioning method prestressed steel bars. The upper flange is mounted on the concrete top plate, the concrete liner is arranged between the upper flange and the bottom plate, and the multiple pre-tensioning method prestressed steel bars are arranged in the concrete liner. A plurality of sets of steel anchoring plates are arranged on the outer sides of the single track train travelling tracks,and the multiple sets of steel anchoring plates jointly bear the post-tensioning method external prestressed steel beam structure. The post-tensioning method external prestressed steel beams can improve the stress state of the track beam, improves the span and rigidity of the track beam, and achieves the purposes of being easy to achieve and operate at the aspect of construction.

Description

technical field [0001] The invention belongs to the technical field of suspended monorail transportation, and more specifically relates to a suspended floor opening combined box-type prestressed track beam system. Background technique [0002] Suspended monorail transit is a new technology of rail transit. There are no technical specifications for suspended rail transit, and there are few reference materials. Although suspended rail transit has a long history in foreign developed countries, it is limited to Japan and Germany have successfully operated lines, and the modern suspended monorail abroad adopts the steel track beam structure with the floor opening. At present, there are only two test lines for suspended monorail in my country, and the test line adopts small-section steel box track beams with bottom plate openings. Steel box girders have problems such as easy buckling, small bearing capacity, large deformation, and difficult linear control, which are the bottlenec...
