螺栓钢筋插销预制装配混凝土柱脚节点
本专利技术涉及一种螺栓钢筋插销预制装配混凝土柱脚节点,属于建筑工程领域。
技术介绍
预制混凝土结构中的构件在工厂中进行生产,然后将预制的构件运送至施工,进行组装。这种建造方式可以大幅提高机械化施工水平,减少施工人员,节省施工时间,加快施工进度,降低建造成本。发展预制混凝土结构是实现建筑工业化的有效途径,可以有效节约资源、降低环境污染,有利于提高国家建筑业现代化发展水平,具有广阔的发展前景。预制混凝土框架结构的柱脚是影响结构性能的关键,只有预制柱脚节点连接可靠,才能保证结构的安全可靠。同时,预制混凝土柱脚节点也是影响预制混凝土框架结构快速、便捷施工的关键因素。目前,常规的预制柱脚节点主要有灌浆套筒连接柱脚、螺栓连接柱脚、焊接连接柱脚等。灌浆套筒连接柱脚节点往往在预制基础上留有伸出钢筋,预制柱预埋套筒,然后灌浆连接,步骤多,效率低;螺栓连接柱脚在现场存在着操作不便的情况,常规螺栓往往只能受拉,而且一般需要预埋辅助钢部件,影响连接效率和性能;焊接连接柱脚在现场狭小的范围内,人工操作不便,焊接质量难以保证,效率低下。
