Upward integrated intelligent bridge fabrication machine and construction method
The invention provides an ascending type integrated intelligent bridge fabrication machine and a construction method. The ascending type integrated intelligent bridge fabrication machine comprises a main beam, the main beam is connected with a formwork device, a front guide beam is arranged at the front end of the main beam, and a rear guide beam is arranged at the rear end of the main beam; the length of the rear guide beam is larger than or equal to that of a span between piers, and the length of the front guide beam is smaller than that of the span between the piers. A reinforcing steel bar binding jig frame is arranged on the rear guide beam and is used for binding box girder reinforcing steel bars; a traveling crown block is arranged on the rear guide beam and the main beam and used for hoisting bound box girder steel bars into the formwork device. According to the invention, the rear guide beam is simultaneously used as a counterweight and a steel bar binding and concrete curing section of the bridge fabrication machine, so that the utilization efficiency of the structure is greatly improved. Steel bar binding and concrete pouring and curing can be carried out at the same time, and the efficiency of bridge construction is greatly improved. And the crown block can directly hoist the box girder reinforcing steel bar from the rear guide beam to the template device of the main beam, conversion is not needed in the process, and deformation of the box girder reinforcing steel bar in the hoisting device conversion process is avoided.
本发明提供一种上行式一体化智能造桥机及施工方法，包括主梁，主梁与模板装置连接，在主梁的前端设有前导梁，在主梁的后端设有后导梁；后导梁的长度大于或等于桥墩间一跨的长度，前导梁的长度小于桥墩间一跨的长度；在后导梁设有钢筋绑扎胎架，用于绑扎箱梁钢筋；在后导梁和主梁上设有可行走的天车，天车用于将绑扎好的箱梁钢筋吊装在模板装置内。本发明使后导梁同时作为造桥机的配重和钢筋绑扎及混凝土养护段，大幅提高了结构的利用效率。钢筋绑扎和混凝土浇筑和养护能够同时进行，大幅提高了桥梁施工的效率。而且天车能够直接从后导梁起吊箱梁钢筋直接吊装到主梁的模板装置，中间无需转换，避免在转换吊装装置的过程中导致箱梁钢筋的变形。
