Bridge reinforcing structure and reinforcing method
According to the bridge reinforcing structure and method, end anchor devices are arranged at the two ends of a bridge, a plurality of steering devices are arranged on the side face of the bridge, and a fiber reinforced composite rib is tensioned between the end anchor devices and the steering devices; two ends of the fiber reinforced composite rib are fixed in the end anchor devices at two ends, and the middle part of the fiber reinforced composite rib is reversed through the steering device; the string type prestressed fiber reinforced composite rib structure is easy to operate, economical and practical, is suitable for reinforcing a bridge structure, can fully utilize the material strength of the composite fibers, and effectively improves the bending resistance and shear bearing capacity of the bridge structure.
本发明提出一种桥梁加固结构及加固方法，在桥梁的两端设置端锚装置，在桥梁的侧面设置多个转向装置，一根纤维增强复合筋张拉于端锚装置和转向装置之间；纤维增强复合筋的两端固定于两端的端锚装置内，纤维增强复合筋的中部通过转向装置换向；从而提出一种操作简单、经济实用的张弦式预应力纤维增强复合筋结构，该结构适用于桥梁结构加固，可以充分利用复合纤维的材料强度，有效提高桥梁结构的抗弯和抗剪承载力。
