Prefabricated pi-shaped beam erecting device and erecting method
The invention discloses a prefabricated pi-shaped beam erecting device and method, and relates to the technical field of bridge construction.The prefabricated pi-shaped beam erecting device comprises a supporting assembly which is arranged on a bridge opening of a prefabricated pi-shaped beam to be erected and used for supporting the prefabricated pi-shaped beam and enabling the prefabricated pi-shaped beam to move on the supporting assembly in the longitudinal bridge direction; the winch is arranged at the end, where the to-be-erected prefabricated pi-beam is placed, of the to-be-erected bridge, the fixed pulley is arranged at the other end of the to-be-erected bridge, and a traction rope of the winch bypasses the fixed pulley to be connected with the prefabricated pi-beam. The method for erecting the prefabricated pi-shaped beam comprises the following steps that supporting assemblies are arranged on bridge supports on the two sides of a bridge opening of the prefabricated pi-shaped beam to be erected; the winch is started, and the to-be-erected prefabricated pi-shaped beam is moved into the bridge opening through the supporting assembly; and the supporting assembly is dismantled, so that the prefabricated pi beam falls onto the bridge support. The problem that in the prior art, when obstacles exist above a bridge or the environment of roads on the two sides of the bridge is poor, a prefabricated pi-shaped beam cannot be erected is solved.
本发明公开了一种预制π梁架设装置及架设方法，涉及桥梁施工技术领域，该预制π梁架设装置包括支撑组件，其设置在待架设预制π梁的桥孔上，用于支撑预制π梁，并可使预制π梁在支撑组件上纵桥向移动；卷扬机和定滑轮，卷扬机设置在待架设桥梁放置待架设预制π梁的一端，定滑轮设置在待架设桥梁的另一端，且卷扬机的牵引绳绕过定滑轮与预制π梁连接。该预制π梁架设方法包括以下步骤：在待架设预制π梁的桥孔两侧的桥梁支座上设置支撑组件；启动卷扬机，利用支撑组件将待架设预制π梁移动至桥孔内；拆除支撑组件，使预制π梁落至桥梁支座上。解决了现有技术中当桥梁上方有障碍物或桥梁两侧道路环境差时，预制π梁无法架设的问题。
