Assembly type box girder assembly temporary buttress and construction method thereof
The invention discloses an assembly type box girder assembly temporary buttress and a construction method thereof, the assembly type box girder assembly temporary buttress comprises a concrete foundation and a steel pipe column, and further comprises a bolt, a first steel plate, preformed holes, a fixing box, a jack, a second steel plate, a diagonal bracing, a horizontal bracing, a plate support,a section steel beam, a baffle, a movable steel pipe and stop blocks; the vertically-installed bolt is arranged on the upper surface of the concrete foundation, and the lower end of the bolt extends into the concrete foundation. The lower end of the bolt penetrates through the preformed holes and are fixed on the upper portions through nuts, the first steel plate and the second steel plate can beconnected together, and if the elevation of the top of the section steel beam needs to be adjusted, the nuts on the upper portion of the bolt can be moved upwards to adjust the jack height to achievefree elevation control. The baffle and the movable steel pipe arranged at the top of the section steel beam can achieve temporary hinge support in the box girder installation process, and meanwhile the stop blocks are symmetrically welded to the two longitudinal ends to prevent the box girder from sliding left and right.
本发明公开了一种装配式箱梁拼装临时支墩及其施工方法，包括混凝土基础和钢管柱，还包括螺栓、第一钢板、预留孔、固定盒、千斤顶、第二钢板、斜撑、水平撑、板支座、型钢梁、挡板、活动钢管和挡块；所述混凝土基础上表面设置有竖直安装的螺栓，所述螺栓下端延伸至混凝土基础内部。螺栓穿过预留孔，使用螺帽在上部固定，能够将第一钢板和第二钢板连接在一起，如果要调整型钢梁顶部标高可上移螺栓上部的螺帽，调节千斤顶高度，实现标高自由控制；型钢梁顶设置的挡板和活动钢管能够实现箱梁安装过程中的临时铰支撑，同时纵向两端对称焊接挡块能够防止箱梁左右滑移。
