The web (13) lies above the bearing plane (26) defined by the bearing-side shoulders (21 , 21').

The storage compartment for products to be refrigerated has a storage base (3) which has at least one retaining element (6) which projects in relation to its storage plane.

A mounting plane technology for a gas panel comprising a plurality of discrete blocks (512).

The mounting plane (504) of the present invention includes a track (501) and a centering element.

The invention relates to a paving stone (1) having stone flanks (2) oriented preferably perpendicular to the laying plane.

The axial dimension H of the flange and the radial dimension L of the support surface are such that: formula (I).

The invention relates to a paving stone (1) used, in particular for rod construction and provided with side flanks (23) preferably perpendicular with respect to a posing position.

The main feature of this case is the depth under laying plane, namely 5400mm.

The centering element and track have a geometrical symmetry that allows for highly precise anchoring of the modular block with respect to the mounting plane (504).

In case of separated pieces, we provide a sticking installation plan, allowing perfect spacing and alignment of the parts.

Our factory workshop makes mosaic craftsmen, following the installation plan generated by our software.
