Prefabricating construction system for bridge segments through short line method
The invention discloses a bridge segment short line method prefabrication construction system which comprises a beam manufacturing platform, a plurality of sets of supporting frames, a translation rail, a moving trolley, a leveling device and a measuring tower. Functional areas of the beam manufacturing platform are divided into a first precast beam area, a matched cast-in-place area, a second precast beam area, an independent cast-in-place area and a transfer area; firstly, an independent cast-in-place area is used for preparing Nth and (N + 2) segment beams, then the Nth and (N + 2) segment beams are sequentially transferred to a first precast beam area and a second precast beam area through a moving trolley, lofting matching is conducted on the Nth and (N + 2) segment beams, and then cast-in-place is conducted on an (N + 1) th segment beam in a matched cast-in-place area between the Nth and (N + 2) th segment beams; meanwhile, an N-4 section beam is prepared in the independent cast-in-place area, and maintenance is completed; the beam sections are shifted, and the N number and the N + 1 number are shifted to a beam storage area through a transfer area; and (N + 2) and (N + 4) are moved to the first precast beam area and the second precast beam area, and the next round of circular prefabrication is carried out. The matching precision is high, and the segmental beam prefabricating efficiency can be greatly improved.
本发明公开了一种桥梁节段短线法的预制施工系统，系统包括制梁台、若干组支撑架、平移轨道、移动小车、调平装置和测量塔，本发明通过将制梁台进行功能区域划分，分为第一预制梁区、匹配现浇区、第二预制梁区、独立现浇区和转运区；首先利用独立现浇区制备N号和N+2号节段梁，然后通过移动小车依次转移至第一预制梁区和第二预制梁区，对N号和N+2号节段梁进行放样匹配，然后在两者之间的匹配现浇区现浇N+1号节段梁；同时在独立现浇区制备N+4号节段梁，养护完成后；进行梁段移位，通过转运区将N号和N+1号移至存梁区；N+2号和N+4号移至第一预制梁区和第二预制梁区，进行下一轮循环预制。本发明匹配精度高，并且能够大幅度提高节段梁预制效率。
