Abstract
A unit joint for connecting two panel units. The narrow edge surface of each panel unit has a plurality of angle guide surfaces abutting a plurality of angle guide surfaces of the adjacent panel unit in order to determine the mutual solid angle of the panel units. The narrow edge surface of each panel unit furthermore has a plurality of apertured coupling ribs, the apertures being substantially coaxial. The ribs on the first panel unit project between the corresponding projections on the second panel unit. A common locking rod extends through all the apertures of the ribs in order to draw the panel units tightly together.
