Reverse newly-built column connecting structure based on self-locking anchoring technology and construction method
The invention discloses a reverse newly-built column connecting structure based on a self-locking anchoring technology and a construction method. When a reinforced concrete frame structure is newly built, all frame columns are prefabricated in a segmented mode, the installed prefabricated columns are lengthened synchronously and jacked synchronously, a floor part is built at the bottom, and reverse construction of newly built on the ground is achieved. In the lengthening process, steel plates at the bottoms and the tops of the adjacent prefabricated columns are welded, annular gaps of reserved grooves in the tops of the columns are grouted, reserved holes of the connecting sleeves are grouted in advance, and when the prefabricated columns are in butt joint, the self-locking anchor rods are opened in inner cavities of the connecting sleeves, so that structural butt joint is achieved. According to the construction method, all floor structures of a building can be constructed within the 2-meter height range of the bottom, construction protection measures such as scaffold erecting and creeping formwork erecting can be omitted, high-altitude operation can be omitted, the capital and resource occupation time can be shortened, and the novel building construction method has wide application prospects.
本发明公开了一种基于自锁锚固技术逆向新建柱连接构造及施工方法。在新建钢筋砼框架结构时，对所有框架柱进行分段预制，对已安装预制柱进行同步接长并同步顶升，在底部进行楼面部分建造，达到地上新建逆向施工。在接长过程中，对相邻预制柱的底部及顶部钢板进行焊接，对柱顶预留凹槽环形间隙进行灌浆，提前对连接套筒预留孔洞进行灌浆，当预制柱对接时，自锁锚杆在连接套筒内腔张开，实现结构对接。该施工方法可实现建筑所有楼面结构均在底部2米高范围内施工，可省去搭设脚手架和爬模等施工防护措施，能免除高空作业，减少资金和资源占用时间，该新型建造施工方法具有广阔的应用前景。
