Abstract

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.

Description

technical field [0001] The invention relates, in particular, to a steel frame fireproof profile with light weight, high strength, fire resistance, corrosion resistance, impact resistance and safety. Background technique [0002] Usually the glass door, window and curtain wall frame is a hollow structure with thin walls, large cross-sectional area and multiple shapes. This kind of steel structure is especially suitable for continuous cold bending production. The so-called cold roll forming technology is a material-saving, energy-saving, and high-efficiency metal forming process. It uses sequentially configured multi-pass forming rolls to continuously process the bending of the plate horizontally, and can process a sheet with good mechanical properties and surface quality. High value-added products with high height and precise dimensions are mostly formed at room temperature, which can be easily combined with punching, riveting, welding and other processes to form a multi-proc...
