The invention discloses a mixed SMA-steel fiber concrete reinforced concrete column formwork and a reinforcing method. The reinforcing method comprises the steps that the surface of a to-be-reinforced concrete column is polished; preparing an SMA-steel fiber concrete filling material; a concrete column reinforcing formwork is installed and reinforced; an SMA-steel fiber concrete filling material is poured; removing the concrete to reinforce the concrete column reinforcing template; and electrifying and exciting the reinforced concrete soil column. According to the concrete column reinforcing method, active prestress is applied to reinforce a building structure, the cracking load of components is increased, and corrosion of internal steel bars is prevented; the template is simple and convenient to assemble and disassemble and can be repeatedly used; the novel excitation mode solves the problem that the efficiency of the traditional excitation mode is low due to low thermal conductivity of concrete; the internal SMA fibers can reduce generation and development of concrete micro-cracks in a fire disaster due to prestress of the internal SMA fibers, heat is prevented from entering the concrete, steel bars are heated and melted, and the reliability of the structure in the fire disaster is improved; the whole construction process is convenient and ideal in cost control.
本发明公开了一种混杂SMA‑steel纤维混凝土加固混凝土柱模板及加固方法，包括打磨待加固混凝土柱表面；制备SMA‑steel纤维混凝土填充料；安装混凝土加固混凝土柱加固模板；浇筑SMA‑steel纤维混凝土填充料；拆除混凝土加固混凝土柱加固模板；对加固完成后的混凝土土柱通电激励。本发明提供的加固混凝土柱方法通过施加主动预应力来加固建筑结构，提高构件开裂荷载，防止内部钢筋锈蚀；模板拼装拆卸简单方便，可重复使用；新型激励方式解决了因混凝土导热率低，传统激励方式效率低下问题；提高加固构件的抗火能力，内部SMA纤维因其预应力可以减少火灾下混凝土微裂缝的产生和发展，阻止热量进入混凝土内部，加热融化钢筋，延长火灾下结构的可靠度；整体施工工艺便捷且成本控制理想。
