Large-span steel-concrete combined arch ring structure suitable for rapid construction

The invention relates to a large-span steel-concrete combined arch ring structure suitable for rapid construction, which comprises two arch ribs, the two arch ribs are horizontally distributed at an interval, and a parallel connection cross brace is detachably arranged between the two arch ribs and is used for connecting the two arch ribs; a cast-in-place concrete top plate is arranged at the top ends of the arch ribs, and a cast-in-place concrete bottom plate is arranged at the bottom ends of the arch ribs. According to the large-span steel-concrete combined arch ring structure suitable for rapid construction, through cooperative use of the two arch ribs, the horizontally-connected cross brace arranged between the two arch ribs, the cast-in-place concrete top plate and the cast-in-place concrete bottom plate, when the large-span steel-concrete combined arch ring structure needs to be transported, the large-span steel-concrete combined arch ring structure can be disassembled into five parts firstly, and at th
