Up to now, according to the main stress members of the bridge, they can be classified into reinforced concrete structures, steel truss structures, composite structures, and the like. Compared with the traditional bridge, the steel structure bridge has the remarkable advantages of being uniform in material, light in weight, high in strength, convenient and fast to construct and the like. Therefore, steel truss bridges have become the preferred structural form for large span or ultra-large span bridges.
In the face of the vigorous development of steel structure bridges in China, how to improve the service performance of the steel structure bridges and the mechanical properties of steel truss members is now a major problem faced by bridge constructors and bridge designers in China. Compared with a reinforced concrete structure, the damage of the steel structure bridge is mainly due to fatigue fracture caused by unreasonable structural form of steel members, and the failure of the whole bridge structure is further caused. The prior art provides various directions of improvement in order to overcome the fatigue fracture defect of steel members.
For example, chinese patent CN103590321a discloses a steel pipe truss arch bridge, it includes two hollow round steel pipe arch ribs, hollow round steel pipe tie beam and stull, the stull welds between two hollow round steel pipe arch ribs, the welding has the crossbeam on the hollow round steel pipe tie beam, still includes arch foot connecting device, the rigid knot is formed through the arch foot connecting plate at the both ends of hollow round steel pipe arch rib and the both ends of hollow round steel pipe tie beam, be connected with truss web member between the belly of hollow round steel pipe arch rib and the hollow round steel pipe tie beam. The steel pipe truss arch bridge has the advantages of convenience in construction and short construction period.
Further, for connection stability of the steel bridge, more screws are usually required to fix the two steel structures; however, the bridge is formed by splicing steel structures, so that a large number of screws are required for fixing; thereby, not only the consumption of screws is increased, but also the stability of the bridge connection is indirectly affected. Based on this, another chinese patent CN115821712a also discloses a steel structure spliced bridge, which comprises a bridge plate, the four corners of the top of the bridge plate are respectively and fixedly provided with a supporting rod, and the front and rear ends of the supporting rod and the top of the bridge plate are respectively and fixedly provided with a transverse fixing frame. The splicing bridge with the steel structure achieves the aim of environment-friendly splicing by being provided with the butt joint blocks, the fixing grooves, the fixing components and the like, and the four fixing plates are respectively clamped in the fixing grooves so as to connect and fix the four butt joint blocks; meanwhile, the two second limiting blocks are positioned on the back surface of the butt joint block, so that the two second limiting blocks and the fixing frame are in a cross shape; fix the mount through two second stoppers, four fixed orifices will run through respectively with the outside of fixed bayonet lock simultaneously to fix through the screw, fix four butt joint pieces through four fixed plates joint respectively in the inside of fixed slot, reduce the use of steel construction concatenation screw, make it reach the effect of province material concatenation.
However, the above-disclosed bridge steel structure does not fully achieve the object of improving the bridge load bearing structure. Specifically, in the prior art, the most common bridge bearing failure mode is that the connection part of the steel structure is stressed for a long time to fall off; or the connection part of the bearing steel structure is easy to generate corrosion fatigue to cause fracture. The existing steel structure also has a scheme of adopting steel cables to strengthen connection, but not all occasions can realize the bridge structure for laying the steel cables.
