<p>A method for manufacturing structural elements (1) substantially made of cellulose-based material comprises the steps of rigidly connecting at least a first planar layer (2a) of cellulose-based material and a superposed alveolar layer (3), also made of cellulose-based material, of rigidly connecting in superposition to the alveolar layer (3) at least a second planar layer (2b) of cellulose-based material, to form a monolithic semi-finished assembly (2a, 3, 2b); and of filling at least a circumscribed portion (4) of the alveolar layer (3) with a filling material suitable for structurally co-operating with the cellulose-based material. The filling material provides the semi-finished product (2a, 3, 2b) with the ability to withstand circumscribed stresses applied around the portion (4) of the alveolar layer (3) involved with the filling. Said filling phase comprises the injection of the filling material through holes (5) obtained on at least one of said first and second planar layers (2a, 2b) of cellulose-based material. <IMAGE></p> |
