Bridge floor beam section erecting device and construction method thereof
The invention relates to a bridge floor beam section erecting device and a construction method thereof in the technical field of bridge erecting equipment, the bridge floor beam section erecting device mainly comprises supporting legs, a main beam supported on the supporting legs, a longitudinal moving mechanism installed on the supporting legs and driving the main beam, and a portal crane running on the main beam, and the portal crane is used for hoisting a beam section to be erected. The supporting positions of the supporting legs are independently arranged on the bearing platform instead of the top surface of the bridge pier or the beam section, so that construction loads on permanent structures such as the bridge pier or the beam section can be avoided, the material consumption of the permanent structures is reduced, and the engineering investment and the construction cost are reduced; and the situation that the beam section construction joint is located on the outer side of the pier when the device is supported on the pier can be avoided, the application range is widened, meanwhile, during one-time through hole displacement of the erecting device, only the supporting leg on the rear side needs to be hoisted away and move forwards, the construction technology is simplified, and the construction efficiency is effectively improved.
本发明涉及桥梁架设装备技术领域内的一种桥面梁段架设装置及其施工方法，主要包括支腿，支撑于支腿上的主梁，安装于支腿上并驱动主梁的纵移机构，以及在主梁上运行的门式起重机，门式起重机用于吊运待架设的梁段。本发明通过将支腿的支撑位置由桥墩或梁段顶面变为独立设置于承台上，既可避免对桥墩或梁段等永久结构产生施工载荷，减少永久结构的材料用量，降低了工程投资及建设成本，又可避免因支撑于桥墩上时无法架设梁段施工缝位于桥墩外侧的情况，拓宽了应用范围，同时架设装置一次过孔移位时，只需要将后侧支腿吊离前移即可，简化了施工工艺，有效提高施工效率。
