<p>This invention refers to Great Span Intermediate Floor Construction particularly designed for construction of public and residential buildings. This is a solution for construction of light-carrying floors based on the static system of a single span beam or continual beam, where the length of the field can be more or less than 10 meters, using semi prefabricated system of construction, that results in complete adaptability of space. The essence of the invention is in prefabrication of longitudinal girders (5) fixed to the supports (2 and 3) of the intermediate floor (1) and to the intermediate column (4a) of the continual intermediate floor (1a). The girder (5) consists of diagonal and triangular and spiral steel reinforcement filling which has in its corners flat steel profiles that are 'welded' by fine grain concrete inside of the upper hollow tile (10) and lower hollow tile (11). Girders (5) may be not not only straight but also horizontally or vertically curved, ring shaped or twisted. Between girders (5) that are evenly moved apart, on the lower hollow tiles, are placed the lower hollow tile blocks (6) and above them are placed at least two rows of light upper non-carrying hollow tile blocks (7). The hollow tile blocks (6 and 7) are made of burned ceramics. In the case of continaual intermediate floor (1a), close to the intermediate columns (4a) instead of the blocks (6) between girders (5) are twice as short lower hollow tile blocks (20) enabling concrete to fill above (20) and into hollow tile blocks (19), forming this way, the lower pressurized zone.</p> |
