Prefabricated column cast-in-place beam joint for steel slideway reverse construction and installation method

GAO ZUOPING / ZHANG CHANG / WU BO / LIU CHUNNIAN / ZHOU ZHIYONG

The invention discloses a prefabricated column cast-in-place beam joint for steel slide way reverse construction and an installation method. When steel slide way jacking reverse construction is adopted, middle layer prefabricated column longitudinal bars adopt straight anchors in a beam column joint area, prefabricated beams adopt straight anchors or bent anchors, the prefabricated column longitudinal bars and cast-in-place beam longitudinal bars are connected through reaming self-locking steel bar connectors, installation seams are reserved between the prefabricated columns, and the prefabricated column faces making contact with the cast-in-place beams are subjected to galling treatment. According to the prefabricated column cast-in-place beam joint scheme for steel slide way reverse construction, multiple tightening actions can be omitted during longitudinal bar installation within the beam range. The node design and installation method is safe and reliable, formwork erecting can be omitted, construction is convenient and fast, environment friendliness is achieved, and application and popularization can be achieved according to a novel building construction method.

本发明公开了一种用于钢滑道逆作施工的预制柱现浇梁节点及安装方法。采用钢滑道顶升逆作施工时，中间层预制柱纵筋在梁柱节点区采用直锚，预制梁采用直锚或弯锚，预制柱纵筋及现浇梁纵筋均采用扩孔自锁钢筋连接器连接，预制柱间预留安装缝，与现浇梁接触的预制柱面进行拉毛处理。本发明的钢滑道逆作施工的预制柱现浇梁节点方案，梁范围内纵筋安装可免除多次拧紧动作。该节点设计及安装方法安全可靠、可免除搭设模板、施工便捷、绿色环保，可按新型建造施工方法推广应用。
