摘要
针对钢管柱带环梁折面柱帽节点施工中存在的模板拼装复杂、支撑体系稳定性差、钢筋加工精度难控制等问题,系统总结了关键施工技术。通过采用BIM技术进行三维建模与模板精准排版,实现了折面柱帽模板的上斜下平双层支撑体系,优化了环梁弧形模板的切割与安装工艺,提高了模板施工效率与质量。环梁主筋采用全自动数控弯圆设备,实现了弯圆、焊接与切断一体化加工,保障了钢筋成型精度与施工效率。混凝土浇筑采用分层、对称、均匀振捣工艺,结合覆膜保湿养护,确保了结构成型质量。实践表明,该技术有效解决了复杂节点施工难题,提升了工程质量与施工效率,为类似工程提供了参考。
The construction of folded column cap joints in steel tube columns with ring beams faces challenges such as complex formwork assembly,insufficient stability of support systems,and difficulties in controlling steel reinforcement accuracy.To address these issues,this study systematically summarizes key construction techniques.Using BIM technology for three-dimensional modeling and precise template positioning,we developed a double-layer support system for the folded column cap formwork,characterized by a sloped top and flat bottom.The installation process for curved ring beam formwork was optimized,enhancing both efficiency and quality.Main reinforcements for the ring beam were processed using fully automated CNC circular bending equipment,integrating bending,welding,and cutting into a continuous workflow,which ensured high precision and improved construction efficiency.Concrete pouring was conducted through a layered,symmetrical,and uniform vibration process,complemented by film-coating for moisture retention,thereby ensuring structural integrity.Practical applications demonstrate that these techniques effectively resolve construction complexities at critical joints,improve project quality and productivity,and offer a valuable reference for similar engineering projects.
