Bridge arch rib erecting method and equipment
The invention provides a bridge arch rib erecting method and equipment, and relates to the technical field of bridge construction. According to the method for erecting the bridge arch ribs, when the arch ribs need to be horizontally spliced, the arch ribs are horizontally spliced through the two bridge floor cranes located on the midspan bridge floor of the bridge body, the defect that the arch ribs need to be transported to the bridge body after being horizontally spliced in a preset horizontal splicing site is overcome, the horizontal splicing transportation time of the arch ribs is effectively shortened, and the construction efficiency is improved. The construction efficiency is improved; after the arch ribs are horizontally spliced, the lifting assembly in driving connection with the arch ribs and the arch feet at the ends of the arch ribs can be erected by driving the bridge deck crane, the arch ribs are driven by the lifting assembly to move upwards to complete butt joint and closure of the arch ribs and the arch feet, and the process that synchronous control is needed when the arch ribs are vertically rotated is avoided in a vertical lifting mode. And meanwhile, the folding joint of the arch rib and the arch springing is located at the lowest end of the arch rib, so that the construction efficiency, the construction quality and the construction safety coefficient of the whole erection and installation process of the arch rib are effectively improved.
本发明提供了一种桥梁拱肋架设方法及设备，涉及桥梁施工技术领域。本发麻的桥梁拱肋架设方法在需要对拱肋进行卧拼时，利用处于桥体的跨中桥面的两个桥面吊机来进行拱肋的卧拼，避免了在预设的卧拼场地进行拱肋卧拼后还需要运输到桥体上的弊端，有效缩短了拱肋的卧拼运输时间，提升了施工效率；拱肋卧拼完成后可通过驱动桥面吊机架设与拱肋驱动连接的提升总成以及位拱肋端部的拱脚，通过提升总成驱动拱肋上移完成拱肋和拱脚的对接合拢，通过竖直提升的方式避免了对拱肋进行竖转作业时需要同步控制的过程，同时拱肋与拱脚的合拢连接处位于拱肋的最低处的端部，有效提升了拱肋整个架设安装过程的施工效率、施工质量和施工安全系数。
