Box girder reinforcing structure and reinforcing method
The box girder reinforcing structure comprises a concrete box girder and a pier supported by the bottom of the concrete box girder, webs are symmetrically arranged on the two sides of the concrete box girder, and a plurality of sets of carbon fiber plates are symmetrically arranged on the webs; filling layers are symmetrically arranged on the two sides of the pier, steel plates are arranged on the outer sides of the filling layers, a plurality of anchor rods are arranged on the outer sides of the steel plates and penetrate through the steel plates and the filling layers to extend into the pier, triangular steel brackets are arranged on the outer sides of the steel plates, and inclined struts are arranged between the triangular steel brackets and the carbon fiber plates. The box girder reinforcing method comprises the following steps that firstly, the triangular steel brackets and the carbon fiber plates are installed; and 2, inclined struts are installed. According to the box girder reinforcing structure, the filling layer and the inclined struts are arranged, so that the strength of the bridge pier and the torsion resistance and overturning resistance of the box girder are improved.
本发明公开的箱梁加固结构，包括混凝土箱梁，混凝土箱梁底部支撑的桥墩，混凝土箱梁两侧对称设有腹板，腹板上对称设置若干组碳纤维板；桥墩两侧对称设有填充层，填充层外侧设置有钢板，钢板外侧设置有若干个锚杆，锚杆贯穿钢板和填充层延伸至桥墩内部，钢板外侧设置有三角钢托架，三角钢托架和碳纤维板之间设有斜撑。本发明箱梁加固方法如下：步骤1：安装三角钢托架、安装碳纤维板；步骤2：安装斜撑。本发明箱梁加固结构通过设置填充层和斜撑，提高了桥墩的强度、箱梁的抗扭能力和抗倾覆能力。
