The invention discloses a fabricated connecting joint of a steel truss bridge. The fabricated connecting joint comprises a joint connecting plate which sleeves the outer side of a transverse beam and provided with an upward opening; two symmetrical oblique beams are rotationally connected to the inner walls of the two sides of the bottom of the joint connecting plate; a plurality of trapezoidal bearing plates which are transversely arranged and located at the top of the transverse beam are slidably connected into the joint connecting plate in a penetrating mode; two grooves are symmetrically arranged in the transverse beam; and first clamping teeth are fixedly connected onto the inner wall of one side of each groove. The fabricated connecting joint is compact in structure; the rigidity of the transverse beam can not be affected when the joint connecting plate is detached and replaced in the later bridge maintenance process; the inclination angles of the oblique beams can be adjusted according to different bridge models through the joint connecting plate, so that the universality of the joint connecting plate is improved, a specific joint connecting plate does not need to be specially customized, and then the production cost of the joint connecting plate is reduced.
本发明涉及一种钢桁架桥梁装配式连接节点，包括套设在横向梁外侧呈向上开口的节点连接板，节点连接板的底部两侧内壁转动连接有相对称的两个斜梁，节点连接板内贯穿滑动连接有呈横行设置且位于横向梁顶部的多个梯形承重板，横向梁内设有相对称的两个凹槽，凹槽的一侧内壁固定连接有第一卡齿，本发明结构紧凑，能在后期检修桥梁中，拆卸节点连接板更换的同时不会对横向梁造成硬性，而且节点连接板还可以针对不同的桥梁造型进行调整斜梁的倾斜角度，增加节点连接板的普适性，无需专门定制特定的节点连接板，进而降低节点连接板的生产成本。
