Over-limit formwork construction process
The invention relates to the technical field of ultra-high and ultra-limit formworks, in particular to an ultra-limit formwork construction technology which comprises the steps that a plate buckle type steel pipe scaffold supporting system is adopted, and monitoring is conducted at all nodes; in the concrete pouring process, according to the concrete pouring speed, deflection deformation observation is carried out on each beam from pouring starting to pouring ending every 30 minutes, concrete pouring is stopped immediately when large deformation is found, and next-step construction can be carried out after measures are taken; the method comprises the following steps: monitoring the deformation of a vertical rod at the bottom of a beam by adopting a level gauge, marking observation datum points on a concrete floor and a beam to be poured, setting a monitoring point in the span of the beam, adopting a steel bar with an elevation mark, and marking one observation point every 2-3 spans of the beam for real-time monitoring; the device is convenient to construct, accurate in structure, convenient to install and good in stability, and normal operation of an engineering project according to various technical and economic indexes required by design is further guaranteed while the safety of building construction and building safety are guaranteed.
本发明涉及超高超限模架技术领域，尤其涉及一种超限模架施工工艺，本发明采用盘扣式钢管脚手架支撑体系，在各节点进行监测；在砼浇筑过程中按照砼浇筑速度，由每道梁从浇筑开始至结束，每间隔30钟进行挠度变形观测，发现有较大变形立即停止砼浇筑，采取措施后方可进行下一步施工；梁底立杆变形采用水准仪进行监测，在待浇筑的混凝土楼板、梁上标示出观测基准点，监测点设置在梁跨中，采用带有标高标记的钢筋，每2－3跨梁标示一个观测点进行实时监测；本发明施工便捷、结构准确、安装方便、稳定性好，保证建筑施工的安全性以及建筑安全性的同时进一步的保证工程项目按照设计要求的各项技术经济指标正常运行。
