Novel U-shaped cross section component

The utility model relates to a U-shaped cross section component, in particular to a novel U-shaped cross section component, which is applied to the technical field of construction of building iron structures. The novel U-shaped cross section component comprises a bottom plate, wherein a U-shaped partition plate group is arranged on the bottom plate; longitudinal partition plate mounting positions are arranged at the left and right ends of the bottom plate respectively; longitudinal partition plates are arranged at the longitudinal partition plate mounting positions; the longitudinal partition plate mounting positions are positioned at the two ends of the U-shaped partition plate group respectively; webs fixed together with the bottom plate are arranged at the upper and lower side ends of the upper part of the bottom plate respectively; the upper parts of the webs are connected through an upper cover plate in a covering way. The novel U-shaped cross section component is compact in structure and high in stability and mechanical performance, the construction efficiency is improved, the construction cost is lowered, and the construction safety is improved.
