Prefabricated composite steel tube concrete latticed column and construction method
A prefabricated composite steel tube concrete latticed column is composed of prefabricated double-steel-tube interlayer concrete column limbs and lattice type connecting pieces between the column limbs. Steel tubes at the outer sides of the prefabricated column limbs are connected with the lattice type connecting pieces through bolts, and interlayer concrete between steel tubes at the inner sides and the outer sides of the column limbs is ultra-high-performance concrete. The upper-layer prefabricated column limbs and the lower-layer prefabricated column limbs are connected through flanges and connecting pipes. The double-steel-tube interlayer confined concrete can effectively reduce the steel distribution rate of column components, save the concrete consumption and reduce the self weight. The latticed column adopts a full-assembly manner, site construction is simple and convenient, and wet operation is not needed. A hollow part of the inner steel tube serves as strength reserve, and the purposes of crane upgrading and plant transformation in the using process can be achieved through secondary pouring of concrete in the hollow part. Based on the characteristics of simple and convenient design and flexible application, the latticed column can be widely applied to medium-sized industrial factory buildings, and the durability, the fire resistance and the anti-seismic property of the latticed column are effectively improved.
一种预制装配复合钢管混凝土格构柱，由预制的双钢管夹层混凝土柱肢和柱肢间的格构式连接件组成。预制柱肢外侧钢管通过螺栓与格构式连接件连接，柱肢内外侧钢管之间的夹层混凝土采用超高性能混凝土。上下层预制柱肢之间通过法兰及连接管连接。双钢管夹层约束混凝土可有效降低柱构件配钢率，节省混凝土用量，减轻自重。格构式柱采用全装配的方式，现场施工简便，无需湿作业。内钢管空心部分作为强度储备，可通过二次浇筑中空部分混凝土达到使用过程中吊车升级、厂房改造的目的。基于设计简便、应用灵活的特点，本发明可广泛应用于中型工业厂房中，有效提高格构式柱的耐久性能、耐火性能和抗震性能。
