Example Embodiment
[0021] figure 1 Is a schematic diagram of the structure of the present invention, figure 2 for figure 1 A view along direction A, as shown in the figure: the arch bridge reinforced composite arch ring of this embodiment includes a main arch ring 1 and a broken line hinged arch 2 located at the lower part of the main arch ring 1. The broken line hinged arch 2 is hinged in turn The load-bearing rod formed by the adjacent hinged load-bearing rods (including the load-bearing rod 22 located in the middle of the broken-line hinged arch and the load-bearing rod 21 located at both ends of the broken-line hinged arch) are hinged to a load-bearing member 23, such as As shown in the figure, the broken-line hinged arch 2 is formed by the bearing rods hinged from the end to the end; wherein the bearing rods 21 located at the two ends of the broken-line hinged arch are pre-compressed. Since the hinge is a rigid connection in a straight direction, the pre-compression The stress is transferre...
