Concrete column joint structure with prefabricated UHPC (Ultra High Performance Concrete) reinforcing section and construction method
The invention discloses a concrete column joint structure with a prefabricated UHPC reinforcing section and a construction method. The concrete column joint structure comprises a column body, a column bottom structure and a lower prefabricated UHPC hollow reinforcing section. A lower grouting sleeve is arranged in the side wall of the lower prefabricated UHPC hollow reinforcing section; a first sealing plug is arranged at the upper end of the lower grouting sleeve; first stirrups are arranged in the side wall of the lower prefabricated UHPC hollow reinforcing section and located on the outer side of the lower grouting sleeve in the vertical direction at intervals. The column body is poured at the top of the lower prefabricated UHPC hollow reinforcing section, and a main reinforcement cage and a lower additional reinforcement cage are arranged in the column body; the lower ends of a group of vertical steel bars in the main steel reinforcement cage extend into a group of lower grouting sleeves; the upper part of the lower additional reinforcement cage is poured in the column body, and the lower end of the lower additional reinforcement cage extends into a cavity of the lower prefabricated UHPC hollow reinforcing section; connecting steel bars are pre-embedded in the top of the column bottom structure; the upper ends of the connecting steel bars are inserted into the lower grouting sleeves. The technical problems that a traditional connection joint is large in steel consumption and high in cost and cannot be repaired after a great earthquake are solved.
一种带有预制UHPC加强段的混凝土柱节点结构及施工方法，包括柱体、柱底结构和下预制UHPC空心加强段；下预制UHPC空心加强段侧壁中设有下灌浆套筒；下灌浆套筒上端设有第一密封塞；下预制UHPC空心加强段侧壁中、位于下灌浆套筒外侧沿竖向间隔布置有第一箍筋；柱体浇筑在下预制UHPC空心加强段顶部，柱体内设有主钢筋笼和下附加钢筋笼；主钢筋笼中的一组竖向钢筋下端伸入一组下灌浆套筒中；下附加钢筋笼上部浇筑在柱体中，下附加钢筋笼下端伸入下预制UHPC空心加强段的空腔中；柱底结构顶部预埋有连接钢筋；连接钢筋上端插入下灌浆套筒中。本发明解决了传统的连接节点耗钢量大，成本高以及无法实现大震后不用修的技术问题。
