• Floor elements of the type under contemplation here, are utilised in order, as a single unit, to make for the creation of a (horizontal) floor surface, such as within a modular house construction.
• said floor element has been constructed and dimensioned so as to be adapted to be able to rest, on ends or on edges, against mutually spaced apart support beams, included in a frame construction for a house body and/or bodies, normally oriented in parallel and structured as metal beams, for instance of steel.

• An individual floor element will then obtain a weight and/or a load bearing rigidity not only depending upon the thickness of the concrete slab but also of the orientation of, the size of and the weight of inlaid metal reinforcing within a wet concrete slab.
• Floor elements of the type and size under contemplation here require major working input in their manufacture and, as regards calculating the dimensioning of the thickness of and the length of the reinforcing metal, such as steel, rods and calculating the orientation of these reinforcing rods.
