Bridge anti-overturning device adapting to multidirectional displacement and construction method thereof
A bridge anti-overturning device adapting to multidirectional displacement comprises an upper anchor box and a lower anchor block, and is characterized in that the lower anchor block is anchored to the side face of a pier through embedded steel bars, the upper anchor box and a steel box girder are welded together, and a high-strength bolt rod is connected between the upper anchor box and the loweranchor block; the upper end and the lower end of the high-strength bolt rod penetrate into the reserved mounting holes of the upper anchor box and the lower anchor block respectively, and the spherical backing rings are mounted at the upper end and the lower end of the high-strength bolt hole respectively and screwed and fixed through the ball nuts so as to meet the requirement for multidirectional displacement. The device has the obvious technical characteristics that firstly, an upper structure and a lower structure are reliably connected through the device, so that the anti-overturning safety of the bridge can be remarkably improved; secondly, the device can adapt to longitudinal and transverse displacement of the bridge and can adapt to a small amount of vertical displacement; thirdly, the anchor box is arranged at the bottom of the beam, so that various conditions such as insufficient beam side clearance and no alignment between a beam web and a pier can be adapted; and fourthly,the device is flexible to install, and the ball nut can adapt to errors in a certain length direction.
一种适应多向变位的桥梁抗倾覆装置，包括上锚箱和下锚块，其特征在于下锚块由预埋钢筋锚固在桥墩侧面，上锚箱与钢箱梁焊接在一起，上锚箱和下锚块之间连接有高强螺栓杆，高强螺栓杆的上下两端分别穿入上锚箱和下锚块的预留安装孔，在高强螺栓孔的上下两端分别安装球型垫环，并用球头螺母拧紧固定，以适应多向变位的需求。本发明有明显的技术特点：其一，上部结构和下部结构通过本装置进行可靠的连接，可显著的提高桥梁抗倾覆安全性；其二，本装置可以适应桥梁纵向和横向的变位，可适应少量竖向变位；其三，梁底设置锚箱，可适用梁侧面净空不足和梁腹板与桥墩没有对齐等各种情况；其四，本装置安装灵活，球头螺母可以适应一定长度方向的误差。
