FRP profile-UHPC-recycled concrete composite beam
The invention belongs to the related technical field of building materials and structural engineering, and discloses an FRP profile-UHPC-recycled concrete composite beam which comprises a formwork, a lower pouring area and an upper pouring area, the lower pouring area and the upper pouring area are sequentially poured in the formwork, the formwork is made of FRP profiles, and the formwork is formed into a groove shape with the two ends closed; the lower pouring area is formed by filling and pouring recycled concrete and forms a tension area of the composite beam; and the upper pouring area is formed by filling and pouring UHPC and forms a pressed area of the composite beam. According to the invention, the excellent compressive property of the UHPC and the excellent tensile property of the FRP can be fully fused, the dead weight of the structure is obviously reduced, the bearing capacity is high, and the material utilization rate is high; in addition, the tensile strength of the concrete is not considered, and the tensile area of the composite beam is filled with the recycled concrete, so that the composite beam is high in economic benefit and good in environmental protection property and has sustainable development value, meanwhile, the composite beam can be fully protected by external FRP profiles, and chloride ion erosion resistance, carbonization resistance and permeation resistance of the composite beam are greatly improved.
本发明属于建筑材料及结构工程相关技术领域，并公开了一种FRP型材‑UHPC‑再生混凝土组合梁，该组合梁包括模板以及先后浇筑在其内部的下部浇筑区和上部浇筑区，其中模板由FRP型材制成，并且成型为两端封闭的槽形；下部浇筑区由再生混凝土填充浇筑而成并且构成组合梁的受拉区域；上部浇筑区由UHPC填充浇筑而成并且构成组合梁的受压区域。通过本发明，能够充分融合UHPC的卓越受压性能和FRP的卓越受拉性能，显著减轻了结构的自重，承载力高，材料利用率高；此外由于不考虑混凝土的受拉强度，组合梁的受拉区采用再生混凝土填充，经济效益高，环保性好，具有可持续发展价值，同时可获得外部FRP型材的充分保护，其抗氯离子侵蚀、抗碳化、抗渗透性能大幅度提升。
