Spatial structure destiny in particular to the covers for large litters

摘要

In a bidirectional or tridirectional reticular spatial structure intended in particular for long-span roofs of the type having members 2, 3 and nodes 4 which are structurally independent, the members comprise several crossmembers 2 connected by the nodes 4 as well as several diagonal members 3 which are convergent and arranged in pyramids having an apex 6' in a corresponding node 4. This node in turn comprises a node body 23 to which the diagonal members are fixed, and at least one group 11, 12, 13 of ties 14, intended for the in-line assembly of at least two crossmembers 2 and subjected to axial loads exerted by the actual crossmembers; furthermore, for each node, the resultant of the axial loads applied to the group 11, 12, 13 of ties 14 passes through the apex 6' of the pyramid.
