Abstract
This invention relates to an ultra-lightweight steel-framed concrete component and its preparation method, belonging to the field of building engineering technology. By filling the steel frame with a lightweight core material and an inner filling layer, not only can the overall strength of the steel frame be improved, but the presence of the lightweight core material can also reduce the overall weight of the steel frame. By creating cavities through holes in the lightweight core material, the weight of the component itself is reduced, facilitating production, transportation, and construction, reducing the self-weight of buildings or structures, and improving seismic performance. In addition, it should be noted that by wrapping the steel frame with an outer cement fiberboard using porous polymer as lightweight aggregate, the steel frame acquires fireproof and corrosion-resistant properties.
