Claim:
A floor plate element ( 1 ) comprising an upper side and two lateral sides for special lightening, insulating and reinforcing intermediate floor constructions and enabling fast building of semi-prefabricated and prefabricated floors with complete insulation, bearing capacity and smaller price, is characterized in that the floor plate element ( 1 ) is a molded plate with a channel ( 2 ) at the upper side of the element, wherein the cross section of said channel ( 2 ) consists of: a trapezoid at the bottom of the channel ( 2 ), said trapezoid having equal flights ( 6 ) and an angle of 70° between each flight ( 6 ) and the bottom of the channel ( 2 ), a rectangle shaped prism with flat sides ( 4 ) in the middle part of the channel ( 2 ), and a trapezoid at the upper side of the channel ( 2 ), said trapezoid having equal flights ( 5 ) and an angle of 135° between each flight ( 5 ) and the lower side of the trapezoid, the upper side ( 7 ) of the floor plate element ( 1 ) is shorter than the lower side ( 8 ), the front and the backside of the floor plate element ( 1 ) consist in the direction from the top to the bottom of the following adjacent surfaces: an upper vertical surface ( 9 ), a sloped surface ( 10 ), a horizontal surface ( 11 ) and a lower vertical surface ( 12 ), and the lateral sides of the floor plate element ( 1 ) are molded, so that one side has a convexity ( 13 ), while the other has a concavity ( 14 ) with corresponding dimensions.
