Roller-type beam body incremental launching construction device

摘要: The invention discloses a roller-type beam body incremental launching construction device. device comprises lower supporting structure and an upper located above the structure, is used for being connected to base, are hinged main hinge shaft, one or more groups of roller trains arranged on part each group auxiliary rotating direction all in bridging direction, body, limiting further included, displace transverse bridge. According device, bottom with different linear changes adapted through freely axis, can be traditional equal-height beams flush bottoms, also suitable variable-height beams, process, rolling friction resistance mainly overcome do work, difficulty lowered, speed accelerated, resources saved.
