The raised floor has a surface made entirely of modular tileswith polyhedral form (1) with side edges (6) perpendicular to thetop (7) forming the basic surface of the tile and resting on thehead of the vertical supporting columns (2) stepping on groundlevel. Usually radial grooves (4) of rectangular section are cutinto the top of the upper head (5) of the vertical supportingcolumns (2), their widths being selected in such a way that thecontacting face sides of the vertical edges (6) of the adajacentttiles (1) should be tightened into the radial groove (4) afterbeing introduced in it vertically.16 claims, 27 figures
