Operating platform for secondary tensioning of bent cap
The operating platform is composed of a hanging basket, the hanging basket comprises a basket body and a lap joint longitudinal beam, and the lap joint longitudinal beam is fixedly connected to the basket body and extends to the upper surface of the cover beam in the longitudinal direction; in the using state, opposite pulling force is applied to the hanging basket, the basket is fixed to the end of the cover beam, at the moment, when the lower surface of the lap joint longitudinal beam is attached to the upper surface of the cover beam for construction, the hanging basket is hoisted in place through the weight of the hanging basket structure, and in-place installation of the operation platform can be completed in combination with opposite tensioning; anchoring damage to the bent cap is not needed on the whole, the construction period is short, and the construction efficiency is greatly improved; compared with the prior art, the pre-stress secondary tensioning device has the advantages that the safety level is improved, the construction cost is reduced, and the overall quality of the cover beam is ensured.
本发明公开了一种用于盖梁二次张拉的操作平台，操作平台由吊篮构成，所述吊篮包括篮筐和搭接纵梁，所述搭接纵梁固定连接于篮筐且沿纵向延伸至盖梁的上表面；使用状态下，所述吊篮被施加朝向对向的拉力并使得篮筐固定于盖梁的端部，此时，搭接纵梁的下表面贴于盖梁上表面施工时，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，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。
