Cavity prefabricated column joint connecting structure and construction method

LIU TAO / FANG GEGE

The invention discloses a cavity prefabricated column joint connecting structure and a construction method, and relates to the technical field of building component construction.The cavity prefabricated column joint connecting structure comprises a cavity prefabricated column, sixteen prefabricated column steel bars are evenly and fixedly installed in the cavity prefabricated column in an inserted mode, and the bottom ends of the prefabricated column steel bars are located outside the bottom end of the cavity prefabricated column; and the joint connecting mechanism comprises a steel bar connecting cylinder. The node connecting mechanism is designed and mounted, a sliding plate is extruded through a prefabricated column steel bar or a connecting steel bar, a clenching sliding block is driven to tighten and clench the prefabricated column steel bar or the connecting steel bar, and the prefabricated column steel bar or the connecting steel bar is fixed in a steel bar connecting cylinder; and the prefabricated column steel bars or the connecting steel bars are prevented from being pulled out of the steel bar connecting cylinder through the tooth grooves, so that the prefabricated column steel bars or the connecting steel bars are simply inserted into the steel bar connecting cylinder to be connected, the connecting steps are saved, the construction time is shortened, and the working efficiency is improved.

本发明公开了一种空腔预制柱节点连接结构及施工方法，涉及建筑构件施工技术领域，包括空腔预制柱，所述空腔预制柱的内部均匀地通过插入固定安装有十六根预制柱钢筋，所述预制柱钢筋的底端位于空腔预制柱的底端之外，节点连接机构，所述节点连接机构包括钢筋连接筒。本发明通过设计安装了节点连接机构，通过在预制柱钢筋或连接钢筋对滑板进行挤压，带动咬紧滑块对预制柱钢筋或连接钢筋进行收紧咬合，使预制柱钢筋或连接钢筋被固定在钢筋连接筒内，再通过齿槽防止预制柱钢筋或连接钢筋从钢筋连接筒内被拔出，使得预制柱钢筋或连接钢筋简单地插入钢筋连接筒内即可进行连接，节省了连接步骤，减少了施工时间，提高了工作效率。
