Background

With the rapid development of economy, the bridge engineering construction in China has been developed rapidly. At present, in the construction of bridge structures, the types of bridge structures are also diversified due to the difference of site construction conditions and construction environments. Generally, bridge construction follows two major parts of pier structure construction and bearing structure construction. For the bridge bearing part, with the development of modern assembly processing and engineering technology, a main structure of an ultra-large bridge is usually constructed in a prefabricated assembly structure mode. For some small and medium-sized bridges, the traditional on-site construction pouring form is still adopted due to the capital construction environment and engineering requirements. The bridge bearing structure adopts a large number of steel bar framework structures, and mainly comprises a main bearing structure of a bridge formed by combining beam column through ribs, stress ribs and bearing surface steel bar mesh distribution ribs. For the steel bar structure, the guardrail construction is started after the bridge deck operation is qualified, secondary steel bar manufacturing is usually needed, the bridge deck and the guardrail construction period cannot be crossed, and the construction period is prolonged.

Patent document No. CN105672137A discloses a construction method of pier body steel bars and a construction method of steel bar framework, which provides a method with simple structure and rapid assembly for pier body steel bar construction of bridge structures through five steps of setting up a bracket, manufacturing the steel bar framework, installing a bottom layer steel bar framework, installing an upper layer steel bar framework and installing pier body steel bars, but the method only relates to the steel bar structure and is only limited to pier construction, and is not applicable to bridge deck construction above the pier. Moreover, the method cannot be effectively applied to other large-area roadbeds and site construction according to the construction area of the pier, and particularly cannot achieve ideal construction effects on other infrastructure structures.

Patent document No. CN105672137A discloses a T-steel reinforced concrete composite beam structure, which is formed by combining a web full length T-steel, an i-steel, and a steel bar to form a steel bar structure through prefabricated steel ribs and prefabricated concrete, and pouring concrete and the steel ribs on the top surface of the T-steel to form an integral composite beam structure. Although the method can effectively improve the strength, the earthquake resistance and other properties of the combined beam, the method has the problems of complex steel rib manufacturing process, difficult field hoisting construction and the like, and the adoption of the process for the concrete bridge deck structure can greatly increase the construction cost.

Patent document No. CN104047223A discloses a light composite structure bridge, which includes a bridge deck, lower main beam section steel, and a bridge pier, wherein a pair of main beam chords are welded to the upper and lower main beam section steel, the upper and lower chords on the same side are welded to each other by a corrugated steel web, flange supporting section steel is welded between the upper main beam chord and the bridge deck, and concrete is filled between the main beam and the bridge deck. Although the method can be manufactured in a factory and reduces the traffic under the bridge during construction, the prefabricated installation in the factory requires welding among chords, webs and the like, a large number of welding procedures are added before the on-site pouring, and the cost of the method is too high for the traditional method adopting a reinforcing mesh structure.
