Flange plate for arch rib chord pipe joint, connecting mechanism and flange connecting method
The invention relates to the field of traffic buildings, and particularly discloses a flange plate, a flange connecting mechanism and a flange connecting method for a steel tube arch rib chord pipe joint of a concrete-filled steel tube arch bridge, the flange plate comprises a plate body, the plate body comprises three flange plate pieces spliced into the plate body, and a plurality of bolt holes are formed in the flange plate pieces in the axial direction in a penetrating mode. According to the scheme, when the flange plates are welded to the stiffening plate, all the flange plates are independent, when one flange plate is welded to the stiffening plate, heat cannot be transmitted to the other flange plates, the heat cannot be mutually transmitted and influenced, welding deformation and residual stress of the flange plates are effectively reduced, and the service life of the flange plates is prolonged. And the disc surfaces of the two disc bodies at the end parts of the two chord pipes can be tightly attached together, so that the mounting precision of the arch rib section is improved.
本发明涉及交通建筑领域，具体公开了一种用于钢管混凝土拱桥钢管拱肋弦管接头的法兰盘、法兰连接机构以及法兰连接方法，包括盘体，盘体包括三个拼合成盘体的法兰盘片，法兰盘片沿轴向贯穿设置有若干螺栓孔。本方案中的法兰盘片在与加劲板焊接时，各个法兰盘片独立，一个法兰盘片在与加劲板焊接时，热量不会传递到另外的法兰盘片上，热量不会互相传递互相影响，有效减小法兰盘片的焊接变形和残余应力，使得两个弦管端部处的两个盘体的盘面能够紧密地贴合在一起，提升了拱肋节段的安装精度。
