<p>The component has a core formed from a construction component material e.g. porous concrete and a reinforcement layer (1) made from a load-bearing material e.g. metal, where dimension of the layer is adapted to the material of the core. The layer has projection units such as nail (3), spike and ligament, and is pressed in the core, so that the units can fit in the core and the layer anchors at a covering surface of the core.</p> |
