Abstract: The possibility of special lightening, insulating and reinforcing intermediate floor constructions enables fast building of semi-prefibraceted and prefabricated floor with complete insulation, bearing capacity and smaller price. Floor elements and are constructed to that already present steel space trusses can be placed in their channels, so that are hastened the building of intermediate floor constructions and makes them cheaper, too. They are minimum shorting at the ends and at the middle of beams, so the works below can be proceeding and the required working time is shorter. The intermediate floor construction is already insulating, so they are no need for insulating, which makes the construction cheaper and the required working time shorter. The plates are enabling the increase of the height of the floor constructions, by tying two beams in the construction. Usage of distance elements and protects the reinforcement in floor construction, so they are no need for corrosion protection.
