Stainless steel composite pipe-concrete-carbon steel member
The invention discloses a stainless steel composite pipe-concrete-carbon steel member. The stainless steel composite pipe-concrete-carbon steel member comprises an external wrapping composite pipe andan internal carbon steel pipe (4); self-compacting concrete or cement mortar (3) is poured between the external wrapping composite pipe and the internal carbon steel pipe (4); the range of the hollowrate X is that X is larger than or equal to 0.09 and less than or equal to 0.073, wherein D0 is the external diameter of the external wrapping composite pipe, Di is the external diameter of the internal carbon steel pipe, and t0 is the wall thickness of the external wrapping composite pipe; and the external wrapping composite pipe is formed by embedding an internal layer carbon steel pipe (2) inthe internal wall of an external layer stainless steel pipe (1). The external wrapping stainless steel composite pipe, a hollow sandwich circular steel pipe concrete member and an external lining stainless steel composite pipe can bear outside load effect and can also restrict internal concrete and protect the carbon steel against being eroded by outside environment; and due to the use of the composite pipe, the pure usage of stainless steel is greatly reduced, and the manufacturing cost is reduced.
本发明公开了一种不锈钢复合管‑混凝土‑碳素钢构件，包括外包复合管和内部碳素钢管（4），所述外包复合管和内部碳素钢管（4）之间浇筑自密实混凝土或水泥砂浆（3）；空心率χ的范围为0.09≤χ≤0.73，其中，，为外包复合管外径，为内部碳素钢管外径，为外包复合管的壁厚；所述外包复合管由内层碳素钢管（2）嵌套于外层不锈钢管（1）内壁构成。该外包不锈钢复合管中空夹层圆钢管混凝土构件，外衬不锈钢复合管不仅可以承受外部荷载作用，还可以约束内部混凝土并保护碳素钢免受外界环境的侵蚀，复合管的使用极大地减少了单纯使用不锈钢的用量，降低了造价。
