The prefabricated concrete column comprises an upper column body, a lower column body and post-pouring concrete, the post-pouring concrete is arranged between the lower end face of the upper column body and the upper end face of the lower column body, and the upper column body and the lower column body each comprise a longitudinal bar, a stirrup used for binding the longitudinal bar and a pre-buried steel pipe short column which is pre-buried and protrudes out of the connecting end. The pre-embedded steel pipe short column of the upper column and the pre-embedded steel pipe short column of the lower column are connected in a welded mode after being connected in an inserted mode; the longitudinal bars of the upper column and the longitudinal bars of the lower column are connected through the semi-grouting and semi-mechanical connecting sleeves, the bottoms of the longitudinal bars of the upper column extend into the semi-grouting and semi-mechanical connecting sleeves, and the tops of the longitudinal bars of the lower column are in threaded connection with the semi-grouting and semi-mechanical connecting sleeves. Therefore, the grouting compactness and grouting quality can be observed during grouting, the error-tolerant rate is high, the quality is reliable, the cost is greatly reduced compared with rigid connection, operation is easy and convenient, construction is convenient, and the reinforcing steel bar connection construction efficiency can be improved.
本发明公开了一种预制装配式混凝土柱，包括上柱、下柱和后浇混凝土，后浇混凝土设置于上柱的下端面和下柱的上端面之间，上柱和下柱均包括纵筋、用于绑扎纵筋的箍筋以及预埋并凸出于连接端的预埋钢管短柱，上柱的预埋钢管短柱和下柱的预埋钢管短柱插接后焊接连接；上柱的纵筋和下柱的纵筋通过半灌浆半机械连接套筒连接，上柱的纵筋的底部伸入半灌浆半机械连接套筒内，下柱的纵筋的顶部与半灌浆半机械连接套筒螺纹连接。因此，可在灌浆时观察灌浆的密实度和灌浆质量，容错率高、质量可靠，成本相比于刚性连接大大降低，且操作简便、便于施工，有利于提高钢筋连接施工效率。
