Construction device and construction method for rigid frame bridge side span closure section and cast-in-place section
The invention discloses a rigid frame bridge side span closure section and cast-in-place section construction device which is used for constructing a closure section and a cast-in-place section between a side span main beam and a side pier and comprises a hanging basket body, and the hanging basket body is installed at the top of the cantilever end of the side span main beam; temporary supports are detachably arranged at the tops of the side piers, and the heights of the temporary supports can be adjusted; the bottom of the cantilever end of the side span main beam and the top of the temporary support are detachably connected with the two ends of a longitudinal beam correspondingly, and the longitudinal beam extends in the horizontal transverse direction. The hanging basket comprises a hanging basket body, the hanging basket body comprises a longitudinal beam middle section and a longitudinal beam middle section, one end of a buckle cable is fixed to the top of the longitudinal beam middle section, the other end of the buckle cable is fixed to the top of the hanging basket body, the length of the buckle cable can be adjusted, and when the length of the buckle cable is adjusted, the height of the longitudinal beam is synchronously adjusted along with the buckle cable. The main beam downwarping problem caused by the fact that the concrete exceeds the square amount in the pouring process is solved, the construction quality is ensured, and the later maintenance and repair work is reduced.
本发明公开了一种刚构桥边跨合龙段及现浇段的施工装置，用于在边跨主梁和边墩之间建造合龙段和现浇段，包括挂篮主体，所述挂篮主体安装于所述边跨主梁的悬臂端顶部；所述边墩的顶部可拆卸的设置有临时支撑，所述临时支撑的高度能够调整；所述边跨主梁的悬臂端底部与临时支撑的顶部分别可拆卸连接有纵梁的两端，所述纵梁沿水平横向延伸；所述纵梁中段的顶部固定有扣索的一端，所述扣索的另一端固定于所述挂篮主体的顶部，所述扣索的长度能够调整，扣索长度调整时，所述纵梁的高度跟随同步调整，本发明解决了现有技术中的边跨合龙段和现浇段需要分段施工，造成施工周期较长的技术问题以及浇筑过程中混凝土超方量引起的主梁下挠问题，确保了施工质量，减少了后期维护和修复的工作。
