Concrete filled steel tubular column reinforcing method based on fiber woven mesh
The invention discloses a concrete filled steel tubular column reinforcing method based on a fiber woven mesh. The concrete filled steel tubular column reinforcing method comprises a concrete filled steel tubular column, the fiber woven mesh, a tension anchoring device and an early strength ECC; the reinforcing method comprises the specific reinforcing steps that the two ends of the fiber woven mesh are wound and pasted to two metal rods of the tension anchoring device through epoxy resin glue respectively, then the fiber woven mesh is wound and installed along the surface of the concrete filled steel tubular column, and prestress is applied in a nut screwing mode; and after the prestress is applied, the early strength ECC is sprayed to cover the woven mesh, and reinforcement is completed. According to the concrete filled steel tubular column reinforcing method, the circumferential prestress fiber woven mesh can achieve a large restraining effect, the restraining effect on core concrete in the concrete filled steel tubular column is further improved, and the bearing capacity of the concrete filled steel tubular column is obviously improved; ECC covering the surface of a steel pipe has the anti-cracking effect, the water seepage resistance and the chloride ion penetration resistance are good, and corrosion of the steel pipe can be inhibited; a reinforcing layer is good in high-temperature resistance, and fire resistance and high-temperature resistance of the concrete filled steel tubular column can be improved.
本发明公开了一种基于纤维编织网的钢管混凝土柱加固方法，包括钢管混凝土柱，纤维编织网，张拉锚固器，早强ECC。具体加固步骤为：用环氧树脂胶将纤维编织网两端分别缠卷粘贴于张拉锚固器的两根金属杆上，然后沿着钢管混凝土柱表面缠绕安装纤维编织网，再过拧螺帽的方式施加预应力。预应力施加完成后，喷射早强ECC覆盖编织网，完成加固。本发明的加固方法中，环向预应力纤维编织网能够起到较大的约束作用，进一步增加对钢管混凝土柱中核心混凝土的约束效应，使钢管混凝土柱承载力明显提升；钢管表面覆盖的ECC具有抗裂效果，防渗水性以及抗氯离子渗透性能好，可抑制钢管锈蚀；加固层耐高温性好，可提升钢管混凝土柱的耐火耐高温性能。
