Concrete beam with built-in grouting square steel tube truss

The utility model relates to a concrete beam with a built-in grouting square steel tube truss, which structurally comprises cuboid-shaped concrete, and the center of the cuboid-shaped concrete is provided with the square steel tube truss. The concrete beam has the advantages that the structural design is reasonable, compared with the prior art, square steel pipes are welded to form the truss, concrete is poured into the steel pipes, the steel pipes are transported to the site to form the concrete beam with the built-in pouring tool slurry, and the concrete beam has the advantages of high bearing capacity, high rigidity and good integrity, can be applied to large-span and super high-rise buildings, and can be widely applied to large-span and super high-rise buildings. The built-in grouting square steel tube truss concrete beam can be used as a main beam and a secondary beam in a casing building storey-adding structure, self-bearing in the construction stage is achieved, and the problem that a formwork cannot b
