| 摘要 |
The invention concerns the manufacture of building panels whereof the resistant elements (2) are assembled with gussets (3, 13) when the mould is being prepared. A skin with non-sealing surface (5) forming the external surface enables degassing (6) when the reactive products expand. Only the skin with non sealing surface (5) is impregnated (7) leaving the external surface of the panel still rough for subsequent coating. The invention enables perfect sealing linkage between the panels, the floor and the framework through a connecting profile (16) and a product injecting pipe (18) free of cavities to be refilled after mounting.
