Maintenance assembly, structure and repair method for hogging moment area of steel-concrete combined continuous beam bridge
The invention relates to the technical field of steel-concrete combined continuous beam bridge repairing, in particular to a steel-concrete combined continuous beam bridge hogging moment area maintaining assembly, structure and repairing method.When the maintaining assembly is poured by concrete and put into a maintaining scene, ribbed steel bars are inserted into clamping teeth, and when the concrete is subjected to pulling force, the ribbed steel bars are inserted into the clamping teeth; the pulling force is transmitted to the one-way box by the ribbed steel bar and further transmitted to the functional steel plate, and when the pulling force is received by the clamping teeth and the elastic element, the clamping teeth and the elastic element generate certain elastic deformation, so that the pulling force borne by the concrete and the maintenance assembly is relieved, and the possibility of concrete cracking is greatly reduced. According to the hogging moment area structure of the steel-concrete combined continuous beam bridge, the steel-concrete combined continuous beam maintenance assembly is adopted to replace a part of ribbed steel bars, the tensile stress of the steel-concrete structure can be reduced, upward movement of a neutral axis can be reduced, the paving layer is arranged above the pouring structure, and the ductility of the paving layer is better than that of the steel-concrete structure; therefore, the possibility of cracking is greatly reduced.
本发明涉及钢混组合连续梁桥修复技术领域，尤其涉及一种钢混组合连续梁桥负弯矩区维修组件、结构及修复方法，本发明维修组件当将维修组件被混凝土浇筑而投入到维修场景中时，带肋钢筋插入到卡齿中，当混凝土受到拉力时，该拉力同时被带肋钢筋传递到单向盒并进一步传递到功能钢板，拉力被卡齿和弹性元件接收时，卡齿和弹性元件产生一定的弹性变形，由此而缓解混凝土与维修组件承受的拉力，大幅减少混凝土开裂的可能。本发明钢混组合连续梁桥负弯矩区结构，采用钢混组合连续梁维修组件替代一部分带肋钢筋，可以减少钢混结构的拉应力，中性轴上移，由于在浇筑结构上方设有一个铺装层，该铺装层的延展性能要优于钢混结构，从而大为减低了开裂的可能。
