Abstract

L'invenzione consiste in un giunto composto da tre elementi in acciaio (due calotte semisferiche tenute insieme da una piastra circolare) assemblate da un perno passante centrale, nel quale convergono i terminali cilindrici, dalla caratteristica forma "a martello", delle aste tubolari che, comunque dirette nello spazio, e collegate tra loro mediante gli stessi giunti, formano strutture reticolari tridimensionali.Il campo di applicazione è la carpenteria posante per la realizzazione di coperture di spazi che richiedono ampie luci con notevoli sovraccarichi.Sia le calotte che la piastra circolare centrale sono dotate all'interno di impronte semi-ovoidali per accogliere i terminali "a martello" delle aste.L'invenzione ha soprattutto il vantaggio, rispetto a sistemi analoghi di sopportare notevolissimi sforzi di trazione e di compressione nelle aste che compongono la struttura, anche di centinaia di tonnellate, grazie alla caratteristica forma a martello dei vari elementi terminali delle aste, che inserendosi nelle piastra di acciaio pieno, sono praticamente impossibilitati a fuoriuscire dal giunto, cosa che accade in sistemi simili. Un altro vantaggio dovuto a questo tipo di sistema, oltre a quello del montaggio effettuato mediante un unico avvitaggio, a quello di aver realizzato una cerniera perfetta ed a quello di poter regolare ed aggiustare la lunghezza delle singole aste, è dovuto al fatto che le due calotte piene permettono la rotazione delle aste dopo il bloccaggio, ciò consente la realizzazione di ogni forma geometrica.
