Kozashiki monorail for track beam, box girder and box girder construction method of

摘要

PROBLEM TO BE SOLVED: To provide a track girder for a concrete saddle-type monorail that makes up a curved section, which track girder can be manufactured easily and inexpensively even if the track girder is large in height.;SOLUTION: The track girder includes a lower girder 1 made of concrete having a plurality of lower segments 10 connected in a bridge axis direction, and an upper girder 2 made of concrete having a plurality of upper segments 20 connected in the bridge axis direction. The lower girder 1 is bent at joints between the lower segments 10 and 10 to form a bent line that is a multilinear approximation of a plane line shape of a curve section. The girder 2 are curved to form an arcuate shape along the plane line shape of the curved section.;COPYRIGHT: (C)2011,JPO&INPIT
