Title:
DOUBLE-TRACK BEAM FOR MAGNETIC-LEVITATION RAIL-WRAP-TYPE RAIL TRANSIT
Document Type and Number:
WIPO Patent Application WO/2017/101769
Kind Code:
A1
Abstract:
Provided is a double-track beam for magnetic-levitation rail-wrap-type rail transit, comprising a left box girder (2) and right box girder (3) erected on a bridge pier (1); the left box girder (2) and right box girder (3) are structurally identical; the left box girder (2) is mounted on the bridge pier (1) by means of a left support base (4), and the right box girder (3) is mounted on the bridge pier (1) by means of a right support base (5); the left support base (4) and right support base (5) are structurally identical; the right side of the left box girder (2) and the left side of the right box girder (3) are fixedly connected together by means of a horizontal crossbeam (6), the horizontal crossbeam (6) has an overall cylindrical shape, and is made of concrete-filled steel tube; the horizontal crossbeam (6) is arranged directly above the bridge pier (1) and there is a spacing between the crossbeam (6) and the bridge pier (1). The left and right box girders are connected by means of the horizontal crossbeam and their overall stiffness is greatly enhanced, to three or more times better than that of individually arranged left and right single beams; accordingly, the improved stiffness significantly reduces the deformation of the structure when subjected to forces, thus satisfying the strict requirements concerning structural deformation in magnetic-levitation engineering projects.
