Claim:
1. Building block ( 11 ) for forming a wall construction ( 100 ), which building block ( 11 ) includes insulating material ( 30 ) and vertical load-bearing walls ( 21 ) extending from one longitudinal side ( 12 , 13 ) of the building block ( 11 ) and towards another longitudinal side ( 12 , 13 ) of the building block ( 11 ), where the insulating material ( 30 ) is provided with recesses ( 31 ) for accommodating the load-bearing walls ( 21 ) for holding them in position, characterized in that an inner part of the insulating material ( 30 ) and load-bearing walls ( 21 ) are provided with recesses ( 32 ) for accommodating at least one longitudinal reinforcing element ( 40 ) binding the load-bearing walls ( 21 ) together in a longitudinal direction of the building block ( 11 ) for forming an inner core ( 20 ) where the load-bearing walls ( 21 ), insulating material ( 30 ) and the at least one reinforcing element ( 40 ) together form the basic load-bearing in the building block ( 11 ), and that the building block ( 11 ) includes at least one outer core ( 50 ) formed by parts of the insulating material ( 30 ) and the load-bearing walls ( 21 ) outside the at least one reinforcing element ( 40 ), where the at least one outer core ( 50 ) has supplementing and reinforcing properties for the inner core ( 20 ), characterized by that the building block ( 11 ) is provided with a centrally longitudinal recess ( 33 ) at a lower side adapted for accommodating a groundsill ( 80 ) or support beams ( 84 ), provided with a centrally longitudinal recess ( 33 ) at an upper side for accommodating a top sill ( 82 ) or support beam ( 84 ), or at both upper side and underside, where recesses ( 32 ) for longitudinal reinforcing elements ( 40 ) are arranged inside the centrally longitudinal recess ( 33 ).
