Novel aluminum alloy-concrete combined beam
The invention provides a novel aluminum alloy-concrete combined beam, and relates to a beam. The existing steel-concrete beam consists of an I-shaped beam or a box-shaped beam, an anti-shearing connecting element and a concrete slab cast on the top of the steel beam, and cannot simultaneously realize the anti-shearing force and the durability. The novel aluminum alloy-concrete combined beam comprises an aluminum alloy sectional material with a cavity, wherein the aluminum alloy sectional material is in a T shape or in a shape like a Chinese character 'ri', and is divided into an upper part and a lower part; the upper part is wider than the lower part; the upper part of the aluminum alloy sectional material is provided with a plurality of cavities; and the cavities of the upper part of the aluminum alloy sectional material are filled with concrete. The technical scheme has the advantages that the pressure-resistant capability of the concrete and good ductibility of the aluminum alloy sectional material are sufficiently realized; the strength and the force bearing capability of the beam are effectively improved; the problems that the combined beam has many welding processes, and the concrete slab can easily crack are solved; and good durability, economic performance and durability are realized.
