Building blocks and support structure

A structure comprising building blocks lying together without being bound by mortar,

• said building blocks havng side walls with grooves therein, whereby the cross-section of said grooves at said building blocks is bounded by one-half of a hexagonal profile,
• chords of supports arranged in said grooves of said walls and located between said building blocks,
• whereby said supports being truss girders including main and auxiliary supports with said auxiliary supports extending through said main supports, wherein the chords of a truss girder each comprise a hexagonal profile and whereby said chord of a said truss girder has a groove opened toward the inside of said support,
• a connection rod extending uninterrupted between said chords of said truss girder and having flexed portions which are secured at the grooves of said chords opened toward the inside of said support, whereby the interior of the chords is filled out with a material which holds the flexed or bent portions of the connection rod in the chords, and whereby the groove in one of said side walls of a building block is offset by the height of the related chord with respect to the groove in that side wall which is located perpendicular to the first-mentioned side wall.
