Bridge expansion joint notch structure and construction and maintenance method thereof
The invention discloses a bridge expansion joint notch structure and a construction and maintenance method thereof. The bridge expansion joint notch structure comprises an expansion joint notch; a pre-embedded connecting piece which is arranged in the bridge body in a pre-embedded mode and located below the expansion joint notch, and the top of the embedded connecting piece is exposed into the expansion joint notch; and connecting reinforcing steel bars which are welded to the embedded connecting pieces when the expansion joint is installed, and the connecting reinforcing steel bars are located in the expansion joint notches after being welded. According to the bridge expansion joint notch structure, bending deformation or deviation of the connecting steel bars caused when large construction machinery and other engineering vehicles pass through the expansion joint notch in the bridge girder construction process can be avoided, the process that the steel bars are broken off to be aligned with the expansion device in the traditional construction process is omitted, and the construction quality of the expansion joint device can be guaranteed.
本发明公开了一种桥梁伸缩缝槽口构造及其施工和维修方法，该桥梁伸缩缝槽口构造包括：伸缩缝槽口；预埋连接件，预埋设置在桥梁梁体中且位于伸缩缝槽口的下方，预埋连接件的顶部露出至伸缩缝槽口内；连接钢筋，连接钢筋在伸缩缝安装时焊接在预埋连接件上，连接钢筋焊接后位于伸缩缝槽口内。该桥梁伸缩缝槽口构造可避免桥梁主梁施工过程中大型施工机械及其他工程车辆通过伸缩缝槽口时对连接钢筋造成弯曲变形或偏位，免去了传统施工过程中对钢筋进行掰移与伸缩装置对齐的过程，有利于保证伸缩缝装置的施工质量。
