BUILDING CONSTRUCTION Abstract A square or rectangular concrete floor slab is first formed, although other shapes, such as circular, are also envisaged. A reinforced concrete column extends vertically upwardly from a generally central location on the floor slab. A separate reinforced concrete structure of basically the same outline as the floor slab and destined to become the roof, is constructed on the floor slab with the aid of a shaping and smoothing screed mounted on the column to rotate about a vertical axis. This latter structure is elevated by means of lifting devices temporarily mounted on the top of the column. With the roof thus suspended, additional concrete is poured into a form that has been placed around and outwardly displaced from the column. The result is the format on of an expanded column that defines an upwardly facing peripheral shoulder on which the roof rests when the lifting force is removed. The screed is designed to be of variable length, e.g. by a hinged or telescopic end, to enable two such buildings to be constructed contiguously without the screed from one interfering with the other. A ceiling layer, including insulation, can be laid on the floor slab when the roof structure is being poured so as to be bounded thereto and thus provide a preformed ceiling when the roof is hoisted into place.
