Rapid maintenance structure and method for plate girder hinge joint
The invention provides a rapid maintenance structure and method for a plate girder hinge joint. The rapid maintenance structure for the plate girder hinge joint comprises an anti-crack paste, a U-shaped steel bar, an asphalt lower surface layer, polyester glass fiber cloth and an asphalt upper surface layer. According to the rapid maintenance method for the plate girder hinge joint, the U-shaped steel bars are implanted into the plate girders in a punching mode, the hinge joint between the plate girders is reinforced through the anti-crack paste and the polyester glass fiber cloth, the lower asphalt surface layer and the upper asphalt surface layer are compacted in a layered mode to form an integral structure, and therefore the hinge joint between the plate girders is rapidly reinforced. In the construction process, the excavation area is small, the construction speed is high, the economical efficiency is high, the hinge joint force transmission performance can be effectively improved, and therefore the passing safety of a bridge is improved.
本发明提供了一种板梁铰缝快速维修结构及方法。板梁铰缝快速维修结构包括抗裂贴、U型钢筋、沥青下面层、聚酯玻璃纤维布以及沥青上面层。板梁铰缝快速维修方法采用打孔方式将U型钢筋植入板梁中，并采用抗裂贴和聚酯玻璃纤维布对板梁之间的铰缝进行加强，沥青下面层与沥青上面层分层压实后形成整体结构，以此对板梁之间的铰缝进行快速加固。本发明在施工过程中开挖面积小、施工速度快、经济性高且能有效提升铰缝传力性能从而提升桥梁的通行安全性。
