Inter-connecting metal building frame - has orifices for installation of service ducts and introduction of concrete

摘要

The interconnecting construction frame for the construction of a building has a rectangular iron frame, U-shaped in section, which contains orifices (13,14) and assembly holes (3,4,5 etc.) in the uprights (1,2) and apertures (17,18) in the cross beams (15,16). The frames are screwed together side-by-side or above one another, so that the orifices align and can be used for the passage of service pipes or cables or for the introduction of concrete. The internal faces of the elements support a partition and the external faces a layer of insulation so that the concrete is contained in the axially intercommunicating frames.
