Fabricated steel tube inner core externally wrapped UHPC arch rib connecting joint, arch bridge and method
The invention discloses an assembly type steel pipe inner core wrapped UHPC arch rib connecting node, an arch bridge and a method, the assembly type steel pipe inner core wrapped UHPC arch rib connecting node comprises hollow steel pipes, the hollow steel pipes are arranged in a sectional mode, the outer diameter of each section of hollow steel pipe is wrapped with a prefabricated UHPC outer wrapping layer, and field butt flanges are arranged at the connecting ends of the adjacent hollow steel pipes; the adjacent hollow steel pipes are connected through on-site butt joint flanges and connecting bolts, a plurality of steel pipe shear nails and flange stiffening steel plates are arranged on the outer diameters of the adjacent hollow steel pipes close to the connecting ends, the adjacent hollow steel pipes are sleeved with steel plates, steel plate shear nails are arranged on the inner walls of the steel plates, and cast-in-place UHPC outer wrapping layers are arranged at the connecting ends of the adjacent hollow steel pipes. The construction method has the advantages that the segment hoisting weight is low, the apparent durability is good, the construction measure investment cost is low, rapid construction of the high-prefabricated arch rib segments can be achieved, the construction quality can be guaranteed, the construction method is simplified, and the construction period is shortened.
本发明公开了一种装配式钢管内芯外包UHPC拱肋连接节点、拱桥及方法，包括空心钢管，所述空心钢管分段式设置，每段空心钢管外径包覆着预制UHPC外包层，所述相邻空心钢管连接端处设有现场对接法兰，所述相邻空心钢管通过现场对接法兰和连接螺栓相连，靠近连接端处的相邻空心钢管外径设有若干钢管剪力钉和法兰加劲钢板，所述相邻空心钢管处套设钢板，所述钢板内壁设有钢板剪力钉，所述相邻空心钢管连接端处设置现浇UHPC外包层。具有节段吊装重量低、表观耐久性能好、施工措施投入费用低，能够实现高预制装配化拱肋节段的快速化施工，可保障施工质量，简化施工方法并缩短施工周期的优点。
