Abstract: A lattice assembly for carrying tiles and electrical and electronic components comprises a plurality of star-shaped lattice elements each having a plurality of arms whose outer ends constitute connecting portions formed with downwardly extending arc-segmental tabs. These connection portions are connected together at anchors each formed with a central cylindrical upstanding abutment body adapted to engage snugly against the ends of a plurality of arms and formed with a plurality of arc-segmental recesses each adapted to receive a respective tab. In addition each connection portion is formed with a split pin having barbs and adapted to be received within sockets in the anchor so that the connection portions can be snap-fitted to the anchors. The elements are each provided at their central node with a spacer body having a height perpendicular to the plane of the element equal to half of the height similarly measured of the anchor so that two such groups of such elements can be mounted together back-to-back.
