PROCESS FOR INSTALLING SITE POURING CONCRETE BEAM BY A MOVING SUPPORT

摘要

PURPOSE:In three supporting beams arranged above the bridge beam, a supporting bean having a central supporting beam suspended at both supporting beams as the guide extension beam is moved, a bridge beam is arranged per span and thereby a rapid and stable srranging operation is performed. CONSTITUTION:Extension beam 2 is jacked down from such a condition as a bridge beam 1a of one span is added to the bridge beam 1, then the extension beam is transferred to the subsequent section by the moving boggies 5 and 6. The supporting part 2a of the transferred beam 2 is fixed on the pier 12, this supporting part 2a is fixed on the pier 12 and supported at three points by the supporting part 2a and the boggies 5 and 6. Subsequently, the supporting beams 3 and 4 are jacked down together with the supporting beam 14, a frame is removed, the supporting beams 3 and 4 are transferred to the subsequent arranging section as a guide of the beam 2. Then, the supporting column 11 is connected to the beams 3 and 4 and supported on the pier 12, then jacked up. Then, the beam 2 is transferred in such a way as the same is slightly projected into the subsequnet arranging section, the beam 2 is jacked up, the frame is assembled, iron reinforcements are applied, then the concrete is applied, cured and the bridge beam 1b is arranged.
