Upper and/or lower faces of members have longitudinal grooves and protrusions. Longitudinal members in each row are fastened by height and adjacent rows of longitudinal members are interjoined by means of one coupling member, as minimum, which opposite faces oriented along longitudinal axis of unit carry grooves and protrusions engaging protrusions and grooves of longitudinal members of adjacent rows. Vertical through and/or blind holes and/or grooves for installation of locks with positioning of coupling members having length multiple of modulus are made in each row along length of block at distances equal to modulus. EFFECT: raised warmth- keeping characteristics of unit, reduced cost for its transportation, erection and finishing operations. 19 cl, 18 dwg
