Steel bridge reinforcing method based on stiff skeleton design concept
The invention discloses a steel bridge reinforcing method based on a stiff skeleton design concept. The steel bridge reinforcing method comprises the following steps that an old steel bridge to be reinforced is prepared; redesigning the structure; reinforcement treatment and durability improvement measures of the nodes are taken; shear keys and binding steel bars are additionally arranged on the old steel bridge component; closing old steel bridge traffic, pouring concrete and curing; and reinforcement is completed. According to the method, the old steel bridge serves as a pouring support for later-stage concrete reinforcement, and finally the steel-concrete structure with high bearing capacity and high durability is formed. The method is widely applicable to steel truss girder bridges, steel truss arch bridges, steel plate I-beam bridges, steel box girder bridges and the like.
本发明公开了一种基于劲形骨架设计理念的钢桥加固方法，包括以下步骤：准备待加固的旧钢桥；结构重新设计；节点的加固处理和耐久性提高措施；旧钢桥构件上新增剪力键和绑扎钢筋；封闭旧钢桥交通，浇筑混凝土并养护；完成加固。本发明将旧钢桥作为后期加固混凝土的浇筑支架，最终形成高承载力、高耐久性的钢混结构物。广泛适用于钢桁架梁桥、钢桁架拱桥、钢板I梁桥、钢箱梁桥等。
