Technical Field
The invention relates to the technical field of constructional engineering, in particular to an auxiliary mounting structure of a steel-concrete composite beam.
Background
Compared with a reinforced concrete beam, the steel-concrete combined beam has the advantages of small structure dead weight and section size, large effective use space, capability of reducing earthquake influence, saving formwork erecting procedures and templates, shortening construction period, increasing beam ductility and the like. Compared with a steel beam, the steel consumption can be reduced, the rigidity is increased, the stability and the integrity are good, the fire resistance and the durability of the structure are enhanced, and the like.
In recent years, steel-concrete composite beams have been more and more widely applied to urban overpasses and building structures in China, and are developing towards the direction of large span. The application practice of the steel-concrete composite beam in China shows that the steel-concrete composite beam has the advantages of a steel structure and a concrete structure, has obvious technical economic benefit and social benefit, is suitable for the national situation of national basic construction, and is one of the main development directions of future structural systems.
However, in the construction process of the steel-concrete composite beam, embedded parts need to be embedded in the concrete beam in advance, the I-shaped steel beam is connected with the embedded parts through the connecting plates when the strength of the concrete meets the requirement, and the joints are welded. Since the weld seam cannot bear weight when it is not cooled, the steel beam must be temporarily fixed by means of a temporary support structure. The problems can be solved by building the scaffold at low altitude, and if the height is too high, the scaffold is not suitable for being built regardless of economic or safety.
For example, patent No. CN201520095956, entitled "prefabricated composite beam segment connecting structure and composite beam containing connecting structure", discloses a connecting structure of composite beam, but it does not relate to the steel beam limiting structure required in the welding and cooling process of welded composite beam.
