Steel pipe arch flange plate stiffening plate, flange plate and mounting method
The invention discloses a steel pipe arch flange plate stiffening plate, a flange plate and a mounting method. The flange plate stiffening plate comprises a stiffening plate body, wherein the stiffening plate body comprises a first connecting surface and a second connecting surface, the first connecting surface is used for being welded to an inner wall of an arch rib steel pipe, the second connecting surface is used for being connected with a flange ring of a flange plate, and grooves are formed in two sides in the length direction of the first connecting surface respectively. The steel pipe arch flange stiffening plate is advantaged in that a contact part of the flange plate stiffening plate and a main arch ring generally does not exceed 500mm, the space distortion is converted into the welding seam gap difference which is less than 1mm and is very small, so the change caused by space distortion of the steel pipe arch bridge can be counteracted by arranging the grooves on the flange plate stiffening plate and performing single-side welding and reverse-side back gouging penetration welding on the flange plate stiffening plate, the flange plate can be manufactured into a standard part, machining difficulty and inspection and acceptance difficulty are reduced, part and component management in the machining process is facilitated, mixed use of the flange plate in the constructionprocess is avoided, workloads are reduced, and a construction period and cost are saved.
本发明公开了一种钢管拱法兰盘加劲板、法兰盘及安装方法，该法兰盘加劲板包括加劲板本体，加劲板本体包括第一连接面和第二连接面，第一连接面用于焊接于拱肋钢管内壁，第二连接面用于连接于法兰盘的法兰环，沿第一连接面长度方向的两侧分别设有坡口。运用本发明的一种钢管拱法兰盘加劲板，法兰盘加劲板与主拱圈接触部位一般不超过500mm，空间扭曲转换为焊缝间隙差不足1mm，微乎其微，因而能够通过在法兰盘加劲板上设置坡口，对法兰盘加劲板单面焊接反面清根熔透焊抵消钢管拱桥空间扭曲带来的变化；并能够将法兰盘制造成标准件，减少加工难度和检查验收难度，方便加工过程的零件部件管理，避免法兰盘在施工过程中混用，减少工作量，节约工期和成本。
