某悬臂浇筑连续梁墩梁临时固结装置设计计算

Design and Calculation of Temporary Consolidation Device for a Cast-in-cantilever Continuous Beam and Pier Beam

预应力钢筋混凝土连续梁悬浇施工时,悬臂两侧存在混凝土恒载、施工荷载和风荷载等不平衡荷载,为保证施工阶段悬臂主梁的抗倾覆稳定,要在墩身和主梁0号块上设置墩梁临时固结装置。结合某工程实例,进行墩梁临时固结装置的设计和计算,为类似工程项目提供参考。

In the suspended poured construction of prestressed reinforced concrete continuous beams, unbalanced loads such as dead load of concrete, construction load and wind load exist on both sides of the cantilever. In order to ensure the anti-overturning stability of the main beams of cantilever in the construction stage, temporary consolidation devices for pier beams should be installed on the pier body and block 0 of the main beam. Combining with a project case, the design and calculation of temporary consolidation devices for pier beams are carried out, so as to provide reference for similar engineering projects.
