Beam bridge reinforcing device and implementation method thereof
The invention provides a beam bridge reinforcing device, a beam bridge comprises a bridge body and a plurality of bridge piers, and the reinforcing device comprises an arched steel pipe component, an arch foot inclined supporting structure, a perforated cover plate, a steel straight support, a perforated steel plate, an anchor bolt and a steel inclined support; the multiple arch foot inclined supporting structures are arranged on the bridge body right above the bridge piers, the arch-shaped steel pipe components are installed between every two adjacent arch foot inclined supporting structures, and the steel straight supports and the steel inclined supports are arranged between the middles of the arch-shaped steel pipe components and the bridge body. Through the structure of the arch-shaped steel pipe component, the steel straight supports and the steel inclined supports, multiple vertical tensioning forces are provided for the midspan position of the girder of the girder bridge body, the load internal force of the girder is transmitted to the arch-shaped steel pipe component through the steel straight supports and the steel inclined supports, the stress of an original girder bridge is optimized, the dead load and live load bending moment stress effect of the girder is remarkably reduced, and the construction efficiency is improved. The service life of the bridge is effectively prolonged.
本发明提供一种梁式桥加固装置，梁式桥包括桥梁本体和若干桥墩，加固装置包括拱形钢管构件、拱脚斜支承结构、开孔盖板、钢直撑、开孔钢板、锚栓与钢斜撑；若干所述拱脚斜支承结构设置在所述桥墩正上方的所述桥梁本体上，相邻两个所述拱脚斜支承结构之间安装有所述拱形钢管构件，所述拱形钢管构件的中部与桥梁本体之间设有所述钢直撑和所述钢斜撑。本发明通过拱形钢管构件、钢直撑与钢斜撑的结构，对梁式桥本体主梁跨中位置处提供多道竖向张拉力，通过钢直撑与钢斜撑将主梁的荷载内力传递给拱形钢管构件，优化了原有梁式桥的受力，显著减小了梁的恒载及活载弯矩受力效应，有效延长桥梁使用寿命。
