Abstract

The invention relates to a precast track beam formwork system in straddle type monorail transit, in particular to an environment-friendly movable precast track beam formwork system in straddle type monorail transit. The system comprises a steel frame system, a track beam transportation system and a steel formwork system. Each steel frame is formed by connection of part of or all of steel uprights, a top beam, a floor beam and bracing pieces, and every two adjacent steel frames are connected longitudinally via longitudinal beams. The steel formwork system is mounted in the steel frame system. By the aid of the formwork system, emission of concrete construction waste and pollution to the environment can be reduced, the formwork system can be moved and assembled along with line construction sites and can be used repeatedly, and limiting conditions for passing bridges, tunnels, streets and the like during track beam transportation are decreased; construction period of a beam fabrication site is shortened, and construction cost of building projects of straddle type monorail transit is lowered.

Description

technical field [0001] The invention relates to a straddle type monorail traffic prefabricated track beam formwork system, which is applied in the prefabrication process of the straddle type monorail traffic track beam. Background technique [0002] The track beam in the straddle monorail traffic is not only the load-carrying beam body but also the track for vehicles to pass. bear the load of the vehicle tires. The three wheel-rail contact surfaces of the track beam are not only load-bearing, but also the track on which the vehicle runs. The three wheel-rail contact surfaces of the track beam change in a spatial curved surface, and the manufacturing precision of the track beam is required to be high. Therefore, strict requirements are placed on the formwork system. [0003] At present, the prefabricated track beam formwork system in straddle monorail traffic mainly includes concrete foundation, left and right concrete reaction walls, steel formwork system and track beam t...
