Lower supporting type reinforced variable-slope bridge section
The invention discloses a lower supporting type reinforced variable-slope bridge section which comprises rut beams, springboards, pull rods, supporting frames, connecting beams and bridge head pins. The track beams are distributed on the left side and the right side of the bridge section, and the two track beams are connected through the connecting beam to form the bridge section; the springboards are arranged on the gradient surfaces of the two ends of the rut beam, one end is connected with the rut beam, and the other end is slidably connected with the bracket; the supporting frames are arranged at the two ends of the rutting beam, the pull rods are installed in the rutting beam, one ends of the pull rods are connected with the supporting frames, the other ends of the pull rods are movably connected with the rutting beam, the supporting frames turn over to drive the pull rods to rise and fall and the springboards to turn over between the gradient face and the horizontal face, and therefore a short bridge can be erected on a single bridge section, and a long bridge can also be erected by using two bridge sections in a combined mode. The bearing capacity is not changed, the barrier width is doubled, and the guarantee use range is expanded.
本发明公开了一种下撑式加强的可变坡桥节，包括车辙梁、跳板、拉杆和撑架、连接梁和桥头销；车辙梁分部在桥节的左右两边，两车辙梁之间通过连接梁连接，形成桥节；跳板设置在车辙梁的两端坡度面上，一端与车辙梁相连，一端与撑架滑动连接；撑架设置在车辙梁的两端，拉杆安装在车辙梁的内部，拉杆一端与撑架连接，另一端与车辙梁活动连接，撑架翻转，带动拉杆起落和跳板在坡度面、水平面之间翻转，能够实现单个桥节架设一座短桥，两个桥节组合使用也能够架设一座长桥，承载能力不变，克障宽度提高一倍，扩大了保障使用范围。
