Steel wire rope reinforcing system and method for continuous beam hogging moment area bearing capacity
The invention provides a steel wire rope reinforcing system and method for continuous beam hogging moment area bearing capacity. A plurality of steel wire rope reinforcing units are installed on the surface of a beam body top plate of a T-shaped continuous beam in parallel in the longitudinal direction of a bridge; each steel wire rope reinforcing unit comprises an anchoring end steel plate, an anchoring end anchorage device, an anchoring end anchor head, a tensioning end steel plate, a tensioning end anchorage device, a tensioning end anchor head and a plurality of steel wire ropes. After theother end of each steel wire rope penetrates through one notch of the tensioning end anchorage device, the end of each steel wire rope is fixed by the tensioning end anchor head; and a cast-in-placeconcrete layer and an asphalt concrete layer are sequentially paved above the steel wire rope reinforcing unit. The method has the advantages that the method is an effective mode for reinforcing the continuous beam with insufficient hogging moment prestress, the hogging moment prestress is reinforced through the steel wire ropes, and compared with a traditional reinforcing mode, the method has theadvantages of being convenient to construct, good in safety, good in economic benefit and the like.
本发明提供一种连续梁负弯矩区承载力的钢丝绳加固系统及方法，在T型连续梁的梁体顶板表面，沿桥纵向方向，平行安装多组钢丝绳加固单元；每组所述钢丝绳加固单元包括锚固端钢板、锚固端锚具、锚固端锚头、张拉端钢板、张拉端锚具、张拉端锚头和多根钢丝绳；每根所述钢丝绳另一端穿过所述张拉端锚具的一个槽口后，其端头采用所述张拉端锚头固定；所述钢丝绳加固单元的上方，依次铺设现浇混凝土层和沥青混凝土层。优点为：本发明是一种针对连续梁负弯矩预应力不足进行加固的有效方式，采用钢丝绳对负弯矩预应力进行加固，和传统加固方式相比，本发明具有施工方便、安全性好、经济效益好等优点。
