Embodiment 1
[0037] Please see attached image 3 , a bridge lateral limiting device based on the tension and compression rod model, including a vertical support limiter 1, a horizontal tie 41 and an oblique compression support 43; a pair of vertical support limiters 1 are respectively arranged on On both sides of the bridge 2, the upper ends of a pair of oblique compression supports 43 are respectively fixedly connected with the lower ends of a pair of vertical support limiters 1, and the connection between the oblique compression supports 43 and the vertical support limiters 1 An obtuse angle is formed between them, and the lower ends of a pair of oblique compression supports 43 extend obliquely inward and downward respectively and are fixed on the pier structure of the bridge 2; 43 and the connecting nodes of a pair of vertical support limiters 1. When the bridge 2 is out of position, a lateral force is generated on the vertical support limiter 1, and the vertical support limiter 1 tran...
