Prestress secondary tensioning construction method for bent cap
The invention discloses a pre-stress secondary tension construction method of a cover beam, which is characterized in that a hanging basket is hoisted in place by utilizing the weight of a hanging basket structure, and in-place installation of an operation platform can be completed by combining opposite tension, so that anchoring damage to the cover beam is not required on the whole, the construction period is short, and the construction efficiency is greatly improved; the pre-stress secondary tensioning can be efficiently and timely performed on the cover beam after the box beam is in place; meanwhile, the tensioning piece provides a full-length safety belt suspension foundation for in-place construction of the box girder, and compared with the prior art, the safety level is improved, the construction cost is reduced, the overall quality of the cover beam is guaranteed, and safety guarantee is provided for construction of the box girder.
本发明公开了一种盖梁的预应力二次张拉施工方法，利用吊篮结构本身的重量，将吊篮吊装就位，结合对向张拉即可完成操作平台的就位安装，整体上不需要对盖梁形成锚固损伤，并且施工周期较短，施工效率大幅提高；能够在箱梁就位后高效及时的对盖梁进行预应力的二次张拉；同时，张拉件还为箱梁就位施工提供通长的安全带悬吊基础，与现有技术相比，提高安全等级，降低施工成本，保证盖梁的整体质量，并且为箱梁的施工提供安全保证。
