A concrete building unit of a sandwich structure, comprising two concrete slabs (1, 2) positioned in parallel at a distance from each other and an insulating layer (3) filling the space between the concrete slabs. Wire trusses (5) are provided between the slabs and are cast in the concrete slabs at the opposite longitudinal edges of the trusses. In order to simplify the assembly of the insulating layer, a truss wire (6) of at least one wire truss (5) is stitched similarly to a sewing thread through an insulating material layer (7) in such a manner that a continuous wire forms loops (6a) protruding from two opposite surfaces of the layer. In a truss element (4) intended for such a building unit, the truss wire (6) is sewn into a beamlike insulating material layer (7) having a rectangular cross-section.

A concrete building unit of sandwich structure comprising: two concrete slabs positioned in parallel at a distance from each other; an insulating layer filling the space between the concrete slabs; and wire trusses having truss wires extending through the insulating layer and fastened to the concrete slabs at opposite edges of the trusses, characterized in that a continuous truss wire of at least one wire truss is stitched through the insulating layer in the shape of a sewing thread in such a manner that the truss wire forms loops protruding from two opposite surfaces of said layer into the respective concrete slab.
