Abstract:
1. A universal hollow modular building block for construction of buildings and structural elements comprising: a block body formed from an outer wall, an inner wall, and at least a first connection element and a second connection element which interconnect said outer wall and said inner wall and form a first through opening in a vertical direction, said block body having longitudinal direction, said block body having an upper side and lower side; a first upper recess extending in said longitudinal direction and formed on said upper side of said block body in at least in one of said connection elements; a first lower recess extending in said longitudinal direction and formed on the lower side of said block body in at least in one of said connection elements; an upper insert made of a heat-insulating material, inserted into said first through opening from the upper side of said block body, and supported by said upper recess; a lower insert made of a heat-insulating material, inserted into said first through opening from the lower side of said block body, and at least partially supporting said block body via contact with said lower recess; a second through opening formed in a vertical direction in said upper insert; a third through opening formed in a vertical direction in said lower insert, so that when said upper insert and said lower insert are inserted into said first through opening and a plurality of said universal hollow modular building blocks are assembled into a structural element such as a wall, said upper recess, said lower recess, said second through opening, and said third through opening of each of said blocks form a continuous lattice-like space suitable for pouring a moldable and curable material which after curing forms a lattice-like load-carrying framework; said block body being divided along said longitudinal direction and in the middle of said connection elements by auxiliary inserts made of a material with high heat-insulating properties.
