1. Device, for constructing three-dimensional structures formed from superposed webs or lattices (12, 12') of elements or bars 18 located in the same plane and connected together by elements (14) located in different planes and oriented in diverse directions in space, called diagonals, these elements being connected by means of assembly nodes, characterised in that each assembly node is constructed in the form of a sphere (16) pierced radially by tapped holes (20) into which the elements (14, 18) of the webs or lattices (12, 12') are positioned and fixed. <IMAGE>
