对沉梁法施工的探讨

结合工程实例,介绍了沉梁法的施工工艺,从钢管架的搭设、钢筋笼的制作、沉梁工序等方面对其工艺要点做了分析,对其施工效果做了检查,表明了沉梁法的施工具有一定的优势,值得推广应用。

不规则多梁交汇的柱梁节点钢筋绑扎施工技术

钢筋混凝土框架结构大型商业建筑,受内部业态多样、功能复杂、布局多变等影响,其结构具有跨度大、梁板布局复杂、柱梁节点处多梁交汇等特点。今针对该柱梁节点的施工难点,通过现场实践研究,总结出改进的柱梁节点移动柱箍沉梁法、隔跨支模原位绑扎法等几种有针对性的钢筋绑扎施工技术。该技术的工程质量不仅符合国家规范要求,还保证了施工安全和施工进度,其技术措施的效果良好。

建筑框架结构梁柱节点柱箍筋质量控制技术创新

建筑框架结构梁柱节点是整个结构体系的重要部位,它是框架抗震的关键节点,而施工中还有较多梁柱节点柱箍筋质量不符合设计要求和规范标准。结合现场实例应用箍筋笼沉梁法,解决了梁柱节点柱箍筋施工质量问题。希望对类似问题的解决有一定的参考。
