Summary: | The invention discloses a prefabricated spliced connecting joint structure of a bridge lower structure. A groove is formed in the top of a bearing platform or the bottom of a bent cap, an upright is located in the groove in the top of the bearing platform or the bottom of the bent cap, the upright and the bearing platform or the bent cap are connected through pre-buried rigid connecting pieces, asplicing material is arranged on the concave surface of the groove in the top of the bearing platform or the bottom of the bent cap, and the upright is spliced to the bearing platform or the bent cap.A splicing joint of the prefabricated upright and the bearing platform or the bent cap can avoid an interface of a component, the position of the splicing joint avoids the largest stress position, the upright is embedded in the bearing platform or the bent cap at a certain depth, a good embedding effect is achieved, the anti-seismic performance is greatly improved, the deeper the groove is, the better the anti-seismic per |
