A dry stack block structure, comprising: at least one course comprising blocks, each comprising: a first and second side walls and a central wall positioned between and parallel to the side walls, wherein the walls are rectangular and having a bottom and top edges located in a first plane and a parallel second plane, a first end and a second end located in a third plane and a parallel fourth plane, perpendicular to the first plane; a first and second end transverse webs connecting the ends respectively of the walls in the third and fourth planes respectively, wherein the end transverse webs having a bottom edge located in the first plane; and two intermediate transverse webs positioned between the third and fourth planes and connecting the second and central walls, the intermediate transverse webs having a bottom edge and a top edge located in the first and second planes.
E04B 2/18 - Walls having cavities in, but not between, the elements, i.e. each cavity being enclosed by at least four sides forming part of one single element using elements having specially designed means for stabilising the position by interlocking of projections or inserts with indentations, e.g. of tongues, grooves, dovetails
E04B 2/26 - Walls having cavities in, but not between, the elements, i.e. each cavity being enclosed by at least four sides forming part of one single element the walls being characterised by fillings in all cavities in order to form a wall construction
E04B 2/22 - Walls having cavities in, but not between, the elements, i.e. each cavity being enclosed by at least four sides forming part of one single element using elements having a general shape differing from that of a parallelepiped
E04B 2/52 - Walls having cavities between, as well as in, the elementsWalls of elements each consisting of two or more parts, kept in distance by means of spacers, at least one of the parts having cavities the walls being characterised by fillings in some of the cavities forming load-bearing pillars or beams
E04B 2/54 - Walls having cavities between, as well as in, the elementsWalls of elements each consisting of two or more parts, kept in distance by means of spacers, at least one of the parts having cavities the walls being characterised by fillings in all cavities in order to form a wall construction
E04B 2/02 - Walls, e.g. partitions, for buildingsWall construction with regard to insulationConnections specially adapted to walls built-up from layers of building elements
