Fire damage reinforcing structure and repairing method for concrete bridge
The invention discloses a fire damage reinforcing structure of a concrete bridge, comprising: a main body unit, which comprises a bridge main body and box girder bottom plate reinforcing steel bars uniformly distributed on the bridge main body, and a fire damage defect area is further burnt on the bridge; the reinforcing unit comprises a plurality of groups of steel plate strips uniformly blocking the opening in the lower end of the fire damage defect area, and each steel plate strip is fixedly connected with the bridge main body through a corresponding embedded screw rod; the repairing method for the fire damage of the concrete bridge is suitable for any one of the reinforcing structures, and the repairing method comprises the following steps that S1, the appearance, the material performance and the fire damage degree of the whole bridge are detected; the repair mortar can solve the problem of definite stress and the problem of insufficient reinforcement wrapped by concrete, and the repair mortar is filled in sequence according to areas, so that the defect that the fire damage defect area is easy to be incompactly filled during filling repair is effectively overcome.
本发明公开了一种混凝土桥梁的火灾损伤加固结构,包括:主体单元,其包括桥梁主体以及均匀分布在桥梁本体上的箱梁底板钢筋,且桥梁上还烧损有火灾损伤缺陷区;加固单元,其包括多组均匀封堵在火灾损伤缺陷区下端开口的钢板条,每个所述钢板条与桥梁主体均通过对应的植入螺杆紧固连接;一种混凝土桥梁的火灾损伤的修复方法,所述修复方法适用于以上任意一种加固结构,且修复方法包括以下步骤:S1:对桥梁整体的外观、材料性能和火损程度检测。本发明修复砂浆既能够解决裹力确实的问题又能够解决混凝土包裹钢筋不足的问题,按区域进行依次填充,有效解决了在填充修复的时候,火灾损伤缺陷区容易出现填充不密实的缺陷。
