SPATIAL SYSTEM
This system was first put on the market in 1955,
by the organization Attwood Development Co. of Muchigen , the largest
one of this type in the world.
The
main carrying element is a tetrahedron whose peaks are connected in the
lower zone. This system carries in two orthogonal directions.
In the images shown in the
upper part the spatial structure of the system with its basic
parameters definitions are presented. Rods are connected in the node by
the bonding element, by screw connection, which has the appearance as
shown below.
