Claim:
A building component comprising: two parallel welded wire grid mats ( 1 , 2 ) formed of grid wires ( 3 , 3 ′, 3 ″, 4 , 4 ′, 4 ″, 5 , 5 ′, 5 ″, 6 , 6 ′, 6 ″) with square or rectangular meshes; individual straight web wires ( 7 , 7 ″) holding said wire grid mats apart at predetermined distances, said web wires extending obliquely, with respect to the wire grid mats, inclined alternately in opposite directions in a trelliswork manner in each row of web wires, said individual web wires being joined at each end to said wire grid mats and being arranged in rows interspersed among the grid wires of the wire grid mats; a one-piece insulating prefabricated block or panel forming a dimensionally stable insulating body ( 8 ) positioned between said grid mats and spanning more than two of said rows of web wires; said insulating body being located at predetermined distances from the wire grid mats and held between, and spaced from, the wire grid mats solely by the web wires, which web wires pierce said insulating body; a plaster base grid ( 21 ) secured to at least one cover surface ( 18 ) of the insulating body; said insulating body having a thickness of between 20 and 200 mm; said at least one cover surface ( 18 ) of the insulating body being formed with a plurality of transverse grooves ( 20 ) positioned to extend horizontally when the building component is erected as part of a building; an outer shell ( 13 ′) of concrete applied to one wire grid mat ( 1 ) and in contact with said at least one cover surface of the insulating body, said outer shell ( 13 ′) of concrete surrounding said one wire grid mat and, together with said one wire grid mat, forming a load bearing part of a building of which said building component forms a part, said outer shell adhering to said plaster base grid and to said plurality of transverse grooves; an additional reinforcing mat ( 15 ) included in said outer shell ( 13 ′), said additional reinforcing mat ( 15 ) being spaced from said one wire grid mat ( 1 ) at a distance that is freely selectable in accordance with static requirements applicable to the building components, said outer shell of concrete being adapted to form the external part of said building; at least one additional reinforcing mat ( 15 , 15 ′); and a plurality of spacer wires ( 24 ) located, apart, at selectable mutual spacing, said spacer wires being connected with the wire gird mat ( 1 ) and the additional reinforcing mat or mats ( 15 , 15 ′) and, optionally, extending perpendicularly to the wire grid mat ( 1 ) and said additional reinforcing mat or mats ( 15 , 15 ′).
