Description

Technical Field

[0001] The utility model relates to the technical field of assembled bridges, in particular to a truss for assembled bridges. Background Art

[0002] As the name suggests, unlike traditional on-site construction methods such as steel bar tying and concrete pouring, for prefabricated bridges, part or all of the components of the bridge's substructure (piers, abutments, cap beams) and superstructure (box beams, slab beams, T-beams) are processed and formed in the prefabricated component factory, then transported to the construction site for hoisting and splicing into the main body of the bridge. The various components of the bridge are mechanically connected through pre-embedded holes, pre-embedded steel bars, and connecting devices processed during the prefabrication production process. The grouting sleeves in the components are used for grouting, so that the concrete fully fills the pores between the components to achieve overall strengthening.

[0003] However, the prior art still has the following problems:

[0004] First, the trusses used in the conventional prefabricated bridges are not easy to install while having high structural strength. Since the trusses need to assist the assembly of the prefabricated bridges, they usually have good support and high structural strength, but most of them are not easy to install and need to be carried as a whole, which is troublesome when used.

[0005] Secondly, the trusses used in the existing technology for prefabricated bridges have limited supporting strength at the lower end. When the bridge to be assembled is long, the longer the truss is, the higher the supporting strength required at the lower end of the truss structure at the farthest end. If the lower end is not provided with a good supporting structure, the truss as a whole may not be stable enough, posing a safety hazard.

[0006] In view of the above problems, the inventor proposes a prefabricated bridge truss to solve the above problems. Utility Model Content

There are four support rods, and the four support rods are distributed in a rectangular array. A connecting plate is commonly fixedly provided at one end of the same side of multiple support rods, and a sleeve is fixedly provided at one end of the connecting plate. Two lower reinforcement tubes are sleeved on the outer surfaces of the two lower support rods, and a lower reinforcement plate is fixedly provided between two lower reinforcement tubes at corresponding positions. The distance between the two main reinforcement plates is the same as the distance between the two lower reinforcement plates, and a vertical rod is provided at the lower end of the lower reinforcement plate.

[0009] Preferably, a cross reinforcement block is fixedly provided on the inner wall of the vertical pole, and four reinforcement grooves are formed between the cross reinforcement block and the vertical pole.
