Wall-building element system and building element for use in the system

A wall-building element system comprising:

• a plurality of sole elements (15) adapted to be assembled to a sole arranged to support insulated wall-building elements;
• a plurality of basic wall-building elements (11) adapted to be assembled horizontally and vertically to a wall;
• and
• a plurality of beams (14), each beam being adapted to be fitted horizontally between each stacked basic wall-building element (11), wherein
• the sole elements (15) and basic wall-building elements (11) have respective widths that are adapted to one another, and each of the sole elements (15) has a top profile that is adapted to a bottom side of a basic wall-building element (11) of the plurality of basic wall-building elements (11),
• the basic wall-building elements (11) are prefabricated with a central load-bearing core member (12) with a form-stable layer of thermal insulation (13) on each side thereof, each core member (12) having a top (12c) and a bottom (12d),
• each thermal insulation layer has a linear recessed region (13a) extending along each side of the respective core member's top (12c) and a linear recessed region (13c) extending along each side of the respective core member's bottom (12d),
• the core member tops each have a top edge that protrudes from its respective recessed level of the thermal insulation layer and the core member bottoms each having a bottom edge that protrudes from its respective recessed level of the thermal insulation layer, the top and bottom edges protruding to a level between the respective recessed level (L13a) of the thermal insulation layer and a non-recessed level (L13) of the thermal insulation layer, while along one vertical side of each basic wall-building element, the core member (12) protrudes to form a tongue (12a) while along an opposite side of the basic wall-building element, the core member (12) is recessed to constitute a groove (12b) adapted to receive the tongue (12a) of an adjacent wall-building element, and
• each of the beams (14) has an H-shaped cross section with a width adapted to the total width of the linear recessed region (13a) along both sides of the core member and a height adapted to a combined height of the top recessed region (13a) and the bottom recessed region (13c) of the wall-building elements (11).
