Abstract

The invention discloses a template-free U-shaped steel concrete combination beam, which comprises a U-shaped steel beam and a concrete beam, wherein the U-shaped steel beam is provided with a bottom plate, two web plates and turned edges; the two web plates are connected at two ends of the bottom plate respectively and arranged side by side in the same direction; the turned edges are connected with the web plates; an accommodating cavity is formed between the two web plates and the bottom plate; and the concrete beam is provided with a main body filled in the accommodating cavity. The combination beam has the advantages of economy and reasonability, material saving, reduction in field work quantity, reduction in labor intensity, neat appearance, flexible form, standardized manufacture, high factory degree, convenient construction, reliable quality and the like.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a formwork-less U-shaped steel-concrete composite beam. Background technique [0002] Bending and shearing members, usually called beams, are a basic member in civil engineering, which mainly refer to horizontal and elongated load-bearing members. The bending and shearing members are usually divided into steel beams, reinforced concrete beams, wooden beams, and composite beams composed of two or more materials. [0003] At present, ordinary steel-concrete composite beams are generally a combination of steel beams and concrete slabs, which generally have problems such as poor fire resistance of steel beams, easy local bending of webs, and large steel consumption; while reinforced concrete beams often have cross-sectional dimensions Large and self-heavy, it requires on-site formwork, reinforcement and concrete pouring, so it has problems such as high labor intensity and time-consu...
