Reinforced structural C-section steel, especially a kind of C-shaped steel with reinforced rib structure at the height of vertical side section, is suitable for large and medium-sized industrial plants and large-scale civil buildings, belonging to the technical field of building materials.
Technical background: the main load-bearing structure of large and medium-sized industrial plants and large-scale civil buildings adopts reinforced C-shaped steel. In the construction process, the reinforced C-shaped steel is usually connected with steel beams and steel columns, and then welded or bolted with steel beams or columns. This method is usually used for steel structures with different types and types.
A kind of C-section steel with rib structure is provided. The C-section steel also improves the height of vertical side section, the width of upper and lower sections, and the width of upper and lower curling edge, so as to increase the processing thickness of C-section steel. It is formed by cold bending of strip steel (black steel strip or galvanized strip), with C-section including vertical edge, and the upper and lower horizontal edges are provided with reinforcing ribs.
Compared with the prior art, the utility model has the following advantages: the newly designed reinforced structural C-section steel improves the vertical section height, the upper and lower section width and the upper and lower curling width of the existing C-shaped steel, and increases one or more stiffener structures and processing thickness in the vertical side extension direction.
