Old bridge widening flexible steel joint convenient to install and replace
The invention provides an old bridge widening flexible steel joint convenient to install and replace. The old bridge widening flexible steel joint comprises a bridge floor bearing part, a first vertical bearing steel part and a second vertical bearing steel part. The first vertical bearing steel part is vertically anchored on the flange end part of the old bridge, and the second vertical bearing steel part is vertically anchored on the flange end part of the new bridge; and one side of the bridge floor bearing part is fastened on the first vertical bearing steel part, and the other side of the bridge floor bearing part is fastened on the second vertical bearing steel part. According to the structure, the bridge bearing part and the vertical bearing part are tightly connected to form an integral stress node to bear the wheel load, and the situation that the newly added vertical load of a new bridge is transmitted to an old bridge can be prevented, so that the safety of the old bridge can be ensured.
本申请提供一种便于安装更换的旧桥拓宽柔性钢节点，其包括桥面承重构件、第一竖向承重钢构件以及第二竖向承重钢构件；第一竖向承重钢构件竖直地锚固于旧桥的翼缘端部上，第二竖向承重钢构件竖直地锚固于新桥的翼缘端部上；桥面承重构件的一侧紧固于第一竖向承重钢构件上，另一侧紧固于第二竖向承重钢构件上。该结构将桥梁承重构件和竖向承重构件紧密连接，形成整体受力节点，承担车轮荷载，还可以防止新桥新增竖向荷载向旧桥传递的情况产生，从而能够保证旧桥的安全。
