Outward rotation type end reinforced pipe shell, double-steel-plate bridge deck structure and synchronous friction welding manufacturing method of double-steel-plate bridge deck structure
The invention discloses an outward rotation type end reinforced pipe shell, a double-steel-plate bridge deck structure and a synchronous friction welding manufacturing method of the double-steel-plate bridge deck structure, and solves the problems that a cavity plate welding joint part is damaged and cracked frequently, and the like. The technical scheme is characterized in that the pipe shell comprises a pipe body, an end cover and a connecting section; the tube body is in a hollow circular tube shape, and the side wall thickness of the tube body is t1; the end cover is connected with one end of the pipe body and seals one end of the pipe body, the end cover is provided with a clamping part, and the clamping part is used for welding equipment to clamp the pipe shell; the connecting section is connected with the other end of the pipe body and sequentially comprises a near welding section and a welding section in the direction from the middle to the end along the center line of the pipe shell, the maximum wall thickness of the near welding section is t2, t2 is larger than t1, and the wall thickness t3 of the welding section is smaller than or equal to t2. The unique end design that the wall thickness of the connecting section is increased first and then decreased improves the buckling resistance, fatigue resistance and shear resistance of a welding joint, a closed-loop welding seam without an arc starting and stopping point is formed in combination with a synchronous friction welding manufacturing process, and the fatigue resistance is better.
本申请公开了一种外转式端部强化管壳体、双钢板桥面结构及其同步摩擦焊制作方法，解决空腔板焊接接头部位破坏开裂高发等问题，其技术方案要点为管壳体包括管体、端盖和连接段；管体为空心圆管状，管体的侧壁厚为t1；端盖与管体一端相连，并将管体一端封闭，端盖上具有夹持部，夹持部用于焊接设备夹持管壳体；连接段与管体另一端相连，沿管壳体中心线从中间往端部的方向，连接段依次包括近焊接段和焊接段，近焊接段的最大壁厚为t2，t2＞t1，焊接段的壁厚t3≤t2。连接段壁厚先增大后减小的独特端部设计，提升了焊接接头抗屈曲、抗疲劳、抗剪的各项性能，结合同步摩擦焊制造工艺，形成了无起弧收弧点的闭环焊缝，抗疲劳性能更好。
