<p>The invention provides a junction device for trussed structures extending in three dimensions, comprising: a central connecting core formed with a plurality of radia11y directed seats, the axis of which are orthogonal to the axis of said core, a plurality of coupling elements designed to be secured to the ends of structural bars which can be partly and coaxially inserted into said radially directed seats; and locking means fitted to said seats for fastening said coupling elements to said core, the outwardly directed ends of said coupling elements being formed with enlarged portions having a planar surface which is inclined with respect to the axis of core, said inclined surface being connected to a tang which is adapted to be coupled to the ends of structural bars and the axis of which is perpendicular to said inclined surface, the dimensions of said tang being adapted to match the bars to which they are to be connected.</p> |
