Prefabricated building-storey sections installation system

The blocks form a supply shaft in a new structure such as a multistorey house, hotel etc., being placed one on top of the other and aligned vertically using solder (sic). The supporting frame of each block protrudes through the ceiling and slightly beyond it into the room above. The individual blocks are installed before pouring the ceiling concrete so as to form a measuring and shuttering column. Metal shuttering is fitted round the first block after alignment and forms part of the ceiling shuttering, the block forming a core for the opening in the ceiling. The next block is then aligned with and fixed to the first one, the metal shuttering for the second ceiling being fixed to it. The process is repeated until the full number of storeys have been installed.
