Locking device on temporary pier of steel box girder cable-stayed bridge and construction method
The invention provides a locking device on a temporary pier of a steel box girder cable-stayed bridge and a construction method.The locking device comprises a jacking device and an elevation adjusting device which are arranged on the upper end face of the temporary pier, and an anchoring box matched with the elevation adjusting device is further arranged on the lower end face of a girder; the elevation adjusting device and the anchoring box are connected through a steel strand. The elevation adjusting device comprises two wedge blocks, wherein the inclined faces of the two wedge blocks make contact with each other, and the two wedge blocks are fixed through a fastener. The problem of timeliness of a traditional steel strand connecting mode is solved, the temporary pier and the main beam are rapidly connected and detached while the advantages of the steel strand are kept, and efficient coordination work of the elevation adjusting device and the jack is achieved; the state that only wind resistance needs to be achieved and the elevation of the main beam does not need to be adjusted can be rapidly converted into the state that the elevation of the main beam needs to be adjusted, and the two states are also conveniently and rapidly removed.
本发明提供了一种钢箱梁斜拉桥临时墩上锁定装置及施工方法，该锁定装置包括设置在临时墩上端面的顶升装置和标高调节装置，所述主梁的下端面还设有与所述标高调节装置配合的锚固箱，所述标高调节装置和锚固箱之间采用钢绞线连接；所述标高调节装置包括两个斜面相互接触的楔块，两个所述楔块之间通过紧固件固定。本发明解决了钢绞线传统连接方式的时效性问题，使其在保持优势的同时快速的实现临时墩与主梁连接与拆除，并实现标高调节装置和千斤顶高效协调工作，可以快速实现从仅有抗风需求不需要调整主梁标高状态转换为需要调整主梁标高的状态，两种状态解除也同样方便快捷。
