摘要

Combination of box elements comprises connecting pieces (1) in the form of a building component with tips with square surfaces (11) formed on the walls of the original building components. The diagonals of the surfaces are identical to the middle separating walls of the edges of the walls of the original component. Holes (111, 121) are formed for inserting spreading elements. Preferred Features: The longitudinal axes of the holes are identical to the axes of the walls of the original building component. The spreading elements have an axial insert on their ends.
