[0002] A bridge is generally composed of a bridge deck, ribs, stiffening plates, crossbeams, longitudinal beams and pier supports, of which crossbeams and longitudinal beams are the main load-bearing components of the bridge, used to support the bridge deck and ribs. The crossbeams are usually located below the bridge deck and distributed along the length of the bridge; the longitudinal beams are perpendicular to the crossbeams and located in the center or on both sides of the bridge deck.
[0003] At present, cross beams and longitudinal beams are generally prefabricated with concrete. During construction, they are transported to the construction area by hoisting machines.
[0004] Although the concrete bridge components in the prior art can realize the load-bearing function of the bridge through the structure of the prior art, there are still the following defects: they are often connected by rigidity. In the actual use of such devices, the connection between the crossbeam and the longitudinal beam is not tight enough, which can easily affect the firmness of the assembly and thus lead to limited load-bearing capacity; therefore, an assembled concrete bridge component is proposed, which can help to complete rapid assembly while improving the firmness of the assembly.
