a. Assembly of structural elements, comprising parallelepipedal structural units which are provided with cavities for lightening and which are intended to be placed side by side and superposed. b. These units have the particular feature that the lightening cavities 4 are localised in specified zones 2, while the outermost zones 3 are zones of high density which can form, after superposition, bearing pillar elements. In addition to main units 1 comprising a lightened central zone and two bearing outermost zones, there is provision for shorter complementary elements constituted by a single bearing zone and a single lightened zone. There is also provision for units comprising a reverse arrangement to that of the main units. These various units may be superposed with a stagger from one layer to another whilst obtaining the superposition of all the bearing zones. c. These units may be used for the production of building walls. <IMAGE>
