The system is incorporated into an external wall and comprises vertical steel columns and horizontal steel beams for supporting floor elements. The steel column cross-section is defined by an entire first flange, two shorter second flanges extending parallel to the first flange so that a gap is left between the opposing free edges of the second flanges, and two webs extending essentially at right angles to the first and second flanges. The beams have a Z-shaped cross-section with an upper flange, an essentially vertical web and a horizontal lower flange for supporting a floor element. |
