Method for reverse fulcrum prepressing in construction of 0 # block bracket of high-pier continuous beam
The invention discloses a method for reverse fulcrum prepressing in construction of a 0 # block bracket of a high pier continuous beam, which comprises the following steps of: S1, mounting pre-embedded finish rolling deformed steel bars at the top of a pier, firstly calculating the model and the number of finish rolling threads, and then mounting the pre-embedded finish rolling deformed steel bars; s2, a reaction frame is installed, specifically, a carrying pole beam is installed firstly, and then the reaction frame is installed; s3, jacks are installed, firstly, the pre-pressing load is calculated, then the jacks with the rated bearing capacity meeting the requirement are selected, and finally the pre-pressing load is applied step by step; s4, construction ending and cleaning are conducted, specifically, the pre-pressing effect is checked firstly, and then the construction site is cleared. A reverse fulcrum pre-pressing method is adopted, the construction efficiency is improved by simulating stress distribution, the pre-pressing effect is verified through visual inspection and non-destructive detection means, it is ensured that the geometric shape and structural performance of a beam body meet the requirements, the construction precision is improved, and the construction cost is reduced. Load distribution and bearing capacity are perfectly improved, and stability of the whole structure is improved.
本发明公开了在高墩连续梁0#块托架施工中用于反支点预压方法，包括以下步骤：S1.墩顶预埋精轧螺纹钢安装,首先计算精轧螺纹型号和数量，然后预埋精轧螺纹钢安装；S2.安装反力架，首先安装扁担梁，然后安装反力架；S3.安装千斤顶，首先计算预压荷载，然后选择额定承载能力满足要求的千斤顶，最后逐级施加预压荷载；S4.施工结束和清理，首先检查预压效果，然后清理施工现场，本申请采用了反支点预压方法，通过模拟受力分布来提高施工效率，通过视觉检查和非破坏性检测手段验证预压效果，确保梁体的几何形状和结构性能满足要求，提高了施工的精度，完美改善荷载分布和承载能力，提高整体结构的稳定性。
