<p>The subject-matter of a ceiling unit for stocking to steel ceiling beams according to this technical solution rests in that it is made as a unit of sacrificial formwork or as a carrier unit. The body of the unit having the shape of a board or of a block with toothing ad graves or similar formation is joined with a suspender to the steel ceiling beams. The suspending is carried out so that the body of the unit laps with its ending parts the low face part of low bands of the steel ceiling beams. More units form the flat field of the low face part of the ceiling. The unit of sacrificial formwork or of the carrier is formed as a board of reinforced concrete and it is joined to the low bands of the beams by screwed suspenders or in the variant solution the unit is joined to the high bands of the beam by wire suspenders buried in the concrete. The body of sacrificial formwork unit represents a composed part, made of a fireproof plasterboard, that is reinforced with OSB boards or wood boards. The body of the part is joined to the low bands of the beam by screw suspenders. In a variant embodiment, a hollow block without any bottom made from OSB or wood is fastened to the fireproof plasterboard from above; and the whole part is joined to the high bands of the beam by wire suspenders, that are passed through the hollow block.</p> |
