Prefabricated prestressed concrete filled steel tubular column and construction method
The invention belongs to the technical field of building construction, and discloses a prefabricated prestressed concrete filled steel tubular column and a construction method. The prefabricated prestressed concrete filled steel tubular column is mainly composed of steel pipes, an oil separant, positioning frames, concrete, steel formworks, bolts, column top connecting pieces and column foot connecting pieces, wherein the steel formworks are located outside the whole device, the inner wall of the outer steel pipe is coated with the oil separant, and the concrete is poured, so that the steel pipe and the concrete are kept in an isolated state; the column top connecting pieces and the column foot connecting pieces are located on the whole column top and the whole column foot respectively and play a role of a support, and the positioning frames are divided into an upper positioning frame and a lower positioning frame. The prestressed concrete filled steel tubular column manufactured through the construction method of the prefabricated prestressed concrete filled steel tubular column is simple in structure, compressive pre-stress is applied to internal concrete in advance, and therefore, the compressive strength of the concrete is improved, the restraining effect of the steel pipe can be achieved at the initial loading stage, and the stress performance is good.
本发明属于建筑施工技术领域，公开了一种预制预应力钢管混凝土柱及施工方法，预制预应力钢管混凝土柱主要是由钢管、油质隔离剂、定位架、混凝土、钢模板、螺栓、柱顶连接件、柱脚连接件组成，钢模板位于整个装置的外部；所述的外钢板的内壁涂有油质隔离剂，浇筑混凝土，使钢管和混凝土保持隔离状态；柱顶连接件以及柱脚连接件分别位于整个柱顶、柱脚，起到支架的作用；定位架分为上定位架、下定位架。本发明提供的预制预应力钢管混凝土柱的施工方法制得的预应力钢管混凝土柱构造简单，预先对内部混凝土施加预压应力，提高混凝土的抗压强度，在受荷初期就能发挥钢管的约束作用，受力性能好。
