Large-gradient steel box girder pushing longitudinal limiting device and limiting construction method
The invention provides a large-gradient steel box girder pushing longitudinal limiting device which comprises a longitudinal limiting device body arranged on the side wall of the high-elevation end of a steel box girder, and the longitudinal limiting device body comprises a transverse rod, a vertical rod and a supporting rod, the vertical rod is perpendicular to the transverse rod and is transversely and slidably connected with the transverse rod, and the supporting rod is fixedly connected with the transverse rod. The supporting rod comprises a large inclined rod and a small inclined rod, one end of the large inclined rod is fixed on a steel plate on the side wall of the steel box girder, the other end of the large inclined rod is fixed at the free end of the cross rod, one end of the small inclined rod is fixedly connected with the large inclined rod, and the other end of the small inclined rod is vertically fixed on the cross rod. According to the longitudinal limiting device which is integrally in a tripod form, through movement limiting of the vertical rod, the operation risk that in the beam falling process, due to the fact that a steel beam has a longitudinal slope, the steel beam is prone to moving in the low-elevation direction in the longitudinal direction is avoided.
本发明提供了一种大坡度钢箱梁顶推纵向限位装置，包括所述钢箱梁高程较高一端的侧壁设置有纵向限位装置，所述纵向限位装置包括横杆和与所述横杆垂直且横向滑动连接的竖杆以及与所述横杆固定连接的支撑杆。所述支撑杆包括大斜杆和小斜杆，所述大斜杆一端固定在钢箱梁侧壁的钢板上，另一端固定在所述横杆的自由端，所述小斜杆一端与所述大斜杆固定连接，另一端垂直固定在所述横杆上。本发明提供的整体为三角架形式的纵向限位装置，通过对竖杆的移动限位，避免了在落梁过程中由于钢梁存在纵坡，钢梁纵向易往高程较低方向移动的操作风险。
