CLAIMS

1. A multichamber wood unit (1), composed of several interconnected oblong wooden elements forming internal spaces, characterised in that it consists of:
- external elements (2), having the vertical connection elements (8, 9) formed on opposite edges of the external elements (2), and a number of connecting grooves (11) on internal sides, the external elements (2) being arranged at a distance from each other and in parallel to each other;
- transversal connecting elements (4), having the dovetails (12) to connect with the grooves (11) of the external elements (2), and grooves (13) on the side surfaces to connect with the internal partition elements (3), the transversal connecting elements (4) being arranged between the external elements (2) perpendicularly to the internal surfaces thereof and connecting the external elements (2) with each other by the inserted-glued connections (5);
internal partition elements (3) arranged in parallel between the external elements (2) and fixed with their ends in the grooves (13) of the transversal connecting elements (4) with the inserted-glued connections (6), thus forming a number of internal chambers (7).

2. A multichamber wood unit (1) according to claim 1, characterized in that the external elements (2) of the multichamber wood unit (1) are of rectangular cross- section and have an upper projection or projections (8) and a lower groove or grooves (9) designed to simplify the vertical connection of multichamber wood units (1) and ensure tightness between separate multichamber wood units (1).

3. A multichamber wood unit (1) according to claim 2, characterized in that the outer side of at least one external element (2) of the multichamber wood unit (1) is convex.

4. A multichamber wood unit (1) according to claim 2 or 3, characterized in that the outer side of both external elements (2) of the wood unit (1) are convex.

5. A multichamber wood unit (1) according to claim 1, characterized in that the inserted-glued connection (5), that connects the external elements (2) with the transversal elements (4), is a dovetail connection.

6. A method for manufacturing a multichamber wood unit (1), consisting of pre- fabrication of the constituents of the wood unit, their assembly and gluing with each other, characterized in:
- working up the external elements (2) by forming the dovetail grooves (11) at pre-determined distances on their internal sides, and the projections (8) and grooves (9) on their upper and lower edges;
- working up the transversal connecting elements (4) by forming the dovetails (12) at their ends and a number of grooves (13) on their side surfaces;
- inserting the transversal connecting elements (4) with their dovetails (12) into the corresponding grooves (11) of the external elements (2) with prior smearing the connection surfaces with glue thus connecting the external elements (2) with each other;
- inserting the internal partition elements (3) of a pre-established length into grooves (13) of the transversal connecting elements (4) thus forming a number of internal chambers (7); and
- drying up the thus assembled multichamber wood unit (1).

7. A method according to claim 6, characterized in that grooves (11) are formed on internal sides of the external elements (2) at a distance from 0.6 to 2.0 m, preferably from 0.8 to 1.4 m.
