<p>This element allows the easy assembly of the walls of a double wall stoneware stoves without any specific knowledge. There are five shaped faces and one smooth, flat face (15). From two front faces (10) protrudes a median rib (12) to which corresponds on the other two front faces (11) a median groove (13). At least one lateral groove (16), corresponding in width (4) and depth to a groove (13), lies on the second lateral face (14), and the distances between the groove (13) and the edge (x) are the same as for the groove (16). Preferably, several grooves (16) are provided, the axis-to-axis spacing of which corresponds to the thickness of the element, as well as perpendicular grooves (17) in the lateral face (14) arranged and formed in the same way. </p> |
