Beschreibung
Zusammenfassung:	The invention discloses a fireproof profile of a steel framework. The fireproof profile comprises a first steel thin-wall specially-shaped pipe and a second steel thin-wall specially-shaped pipe, wherein the whole first steel thin-wall specially-shaped pipe is of a rectangular frame structure, and convex ridges are arranged at two top corners, which are positioned at the lower side, of the rectangular frame structure; the second steel thin-wall specially-shaped pipe is arranged above the first steel thin-wall specially-shaped pipe; the whole second steel thin-wall specially-shaped pipe is of a rectangular frame structure, and a groove is inwards sunken in a top corner, which is positioned at the upper side, of the rectangular frame structure; the first steel thin-wall specially-shaped pipe and the second steel thin-wall specially-shaped pipe are connected through a butt-joint column; a fireproof asbestos block is arranged in a space between the first steel thin-wall specially-shaped pipe and the second steel thin-wall specially-shaped pipe. The fireproof profile of the steel framework is light in weight, high in intensity, fireproof, erosion-resistant, anti-impact and high in safety.
