A method of manufacturing insulated concrete elements (2) comprising at least one supporting concrete layer (6) and at least one insulation layer (12). Recesses (14) are made in the insulation layer to form channels (20), made by mechanical working, said working giving the interior of each channel a rough surface (22). Fresh concrete (25) is poured into a mould (24) which has been pre-equipped with reinforcement (28) to make the supporting concrete layer (6) and the insulation layer (12) is then pressed against the concrete in the mould. The concrete is made, through vibration, to fill out each channel (20) and after hardening, constitutes both the supporting concrete layer (6) and ridges (10), integral with the concrete layer, in each channel (20). The ridges serve as anchoring means for the insulation layer. The channel in cross section can be T-shaped, dovetailed, or U-shaped. |
