Novel circumferential prestress assembly type outer wrapping column base and construction method
The invention discloses a novel circumferential prestress assembly type outer wrapping column base and a construction method, the structure comprises a foundation, a steel column installed on the foundation and an outer wrapping module, and pins are arranged outside the steel column; the outer wrapping module comprises four outer wrapping column foot blocks, and the four outer wrapping column foot blocks are mutually spliced in the middle to form a space allowing a steel column to penetrate through in an enclosing mode; pin holes for inserting pins are formed in the outer wrapping column foot blocks; prestressed ducts which are sequentially communicated are formed in the four outer wrapping column foot blocks, prestressed tendons are arranged in the prestressed ducts, one ends of the prestressed tendons are anchored at the internal connectors, and the other ends of the prestressed tendons penetrate out of the external connectors and are anchored; reserved steel bars are arranged on the foundation, and grouting sleeves connected with the reserved steel bars are arranged at the lower ends of the outer wrapping column foot blocks; micro-expansion concrete is poured into the steel column, and cement grout is poured between the steel column and the outer wrapping module. The column foot has the advantages of being convenient to machine and install, reliable in force transmission, good in mechanical property, capable of saving energy, reducing emission and the like, and guidance is provided for design and construction of the assembly type externally-wrapped column foot.
本发明公开了一种新型环向预应力装配式外包柱脚及施工方法，结构包括基础、安装在基础上的钢柱以及外包模块，钢柱外设有销钉；外包模块包括四个外包柱脚块，四个外包柱脚块相互拼接于中部围闭形成用于穿过钢柱的空间；外包柱脚块上设有用于插入销钉的销钉孔；四个外包柱脚块上设有依次连通的预应力孔道，预应力孔道内设有预应力筋，预应力筋一端于内部接口处锚固，另一端从外部接口处穿出并锚固；基础上设有预留钢筋，外包柱脚块下端设有与预留钢筋连接的灌浆套筒；钢柱内灌注有微膨胀混凝土，钢柱与外包模块间灌注有水泥浆液。本发明具有加工安装方便、传力可靠、力学性能好、节能减排等特点，为装配式外包式柱脚的设计和施工提供指导。
