FIELD: construction.SUBSTANCE: invention relates to a construction element containing the first and the second fibrous panel elements located parallel to each other and a filling element located between the first panel element and the second panel element; with that, the filling element is made in the form of a solid plate, the plane of which is generally parallel to the first and the second panel elements; with that, the filling element includes the first system of cone-shaped wells projecting out of the plate plane. With that, the element is characterised by the fact that the filling element is obtained by forming or vacuum forming from material based on cellulose fibre; with that, the first system of cone-shaped wells represents a set of flattened cones with an upper part and a lower part, which have the shape of a round. One side of the plate plane has a continuous flat surface; the system of cone-shaped wells projects on the other side of the plate plane; and the system of cone-shaped wells has a conicity angle of 5-45°.EFFECT: construction element has strength and durability; with that, it is easy- and cheap-to-manufacture.15 cl, 18 dwg |
