Precast concrete column structure and construction method thereof
The invention relates to a precast concrete column structure. The precast concrete column structure comprises a first precast section, a core section, a second precast section and grouting holes, wherein the first precast section is formed in a precast mode, and a plurality of first steel bars are pre-buried in the first precast section; the core section is precast and arranged at the top of the first precast section, the first steel bars penetrate through the core section through holes and are partially exposed out of the top of the core section, and connecting pieces which partially protrudeoutwards and are fixedly connected with a cross beam are pre-buried in the core section; the second precast section is precast and arranged at the top of the core section, a plurality of second steelbars are pre-buried in the second precast section corresponding to the first steel bars, and the first steel bars extend into the second precast section through inserting holes and are in butt jointwith the second steel bars; and the grouting holes communicate with the joints of the first steel bars and the second steel bars and are formed in the second precast section. According to the precastconcrete column structure, the problem that a precast concrete column is difficult to construct is effectively solved, the connecting process is simplified, a temporary support does not need to be additionally erected, the construction efficiency is improved, and the overall stability of the concrete column is improved.
本发明涉及一种预制混凝土柱结构，包括：预制形成的第一预制段，该第一预制段中预埋有若干第一钢筋；预制且置于第一预制段顶部的核心段，该第一钢筋通过贯通孔穿过核心段并部分字核心段的顶部露出，该核心段中预埋有部分向外凸伸且供与横梁固定连接的连接件；预制且置于核心段顶部的第二预制段，该第二预制段中对应第一钢筋预埋有若干第二钢筋，该第一钢筋通过插接孔伸入第二预制段中并与第二钢筋对接连接；以及与第一钢筋和第二钢筋的连接处相连通且开设于第二预制段的注浆孔。本发明有效地解决了预制混凝土柱施工困难的问题，简化连接工艺，不需要额外搭设临时支撑，提升施工效率，提升混凝土柱的整体稳定性。
