Novel GFRP pipe-thin steel plate-concrete column
The invention discloses a novel GFRP pipe-thin steel plate-concrete column, and belongs to the technical field of building structure engineering. The composite pipe comprises a GFRP pipe, a thin steel plate and concrete, the thickness of the thin steel plate ranges from 1.5 mm to 3 mm, the thin steel plate is curled to form an inner steel pipe with the outer diameter equal to or slightly smaller than the inner diameter of the GFRP pipe, the outer GFRP pipe and the inner steel pipe are concentrically arranged, the GFRP pipe and the inner steel pipe form the composite pipe, the concrete is poured into the inner steel pipe, and the outer GFRP pipe is connected with the inner steel pipe. And the GFRP pipe and the internal steel pipe formed by curling the thin steel plate are equal in height as well as the concrete column. The thin steel plate and the GFRP pipe are better attached together through tension generated by curling the thin steel plate, gaps are reduced, the probability that the thin steel plate is rusted is reduced, meanwhile, the problem that the GFRP pipe and the thin steel plate are not prone to nesting is solved, and the construction difficulty is reduced. As the thin steel plate does not need to be welded, the residual stress of a welding seam is avoided, the construction cost is reduced, and the engineering quality and the working efficiency are improved. And the applicability, safety and stability in the field of constructional engineering can be met.
一种新型GFRP管‑薄钢板‑混凝土柱，属于建筑结构工程技术领域。所述包括GFRP管、薄钢板和混凝土，所述薄钢板厚度为1.5‑3mm，通过卷曲形成外径等于或略小于GFRP管内径的内部钢管，所述外部GFRP管和所述内部钢管同心设置，所述GFRP管、内部钢管构成复合管，所述内部钢管内浇筑混凝土，所述GFRP管与薄钢板所卷曲形成的内部钢管以及混凝土柱等高。利用卷曲薄钢板产生的张力使薄钢板与GFRP管更好的贴合在一起，减少缝隙，降低薄钢板被锈蚀的机率，同时解决GFRP管与薄钢板不易嵌套的问题，降低施工难度。由于薄钢板不需要焊接，避免了焊缝的残余应力，减少施工成本，提高了工程质量和工作效率。有利于满足建筑工程领域使用的适用性、安全性和稳定性。
