<p>The connections for structures consist of sets of sockets going right through the structures. The sockets are the same shape for all the structures so that the various sets of sockets can be aligned. Fitments are inserted into each alignment. Each fitment consists of an expansion piece which locks the fitments inside the sockets, at right angles to the contact surfaces between the structures. The expansion pieces consists of sprung steel, flexible pins, with a central cavity inside and divided along a generatrix. The structures are reinforced with metal shuttering the other surface of which is touched by the pins.</p> |
