FIELD: control joints, particularly packing of metal and plastic or elastic materials for joint forming. ^ SUBSTANCE: assembly comprises the first profiled member secured to one edge of the first concrete panel and the second profiled member fastened to one edge of the second concrete panel. The profiled members are connected with each other by removable connection strips so that a gap is created between the profiled members. The profiled members and the connection strips define single continuous extruded profile unit formed of aluminum. Connection strip edges are fastened to profiled members by means of ultra-thin bridges, which maintain connection between profiled members during panel casting operation. Control joint assembly is installed at design height on concreting base before panel casting. During panel casting connection strips cover gaps between profiled members and prevent gap filling with concrete. After concrete hardening the connection strips are separated from the panel and the gaps are filled with elastic sealant. The first profiled member is used as mold for control joint forming and is made so that concrete panels may be cast from different control joint sides the at any time. ^ EFFECT: increased efficiency. ^ 9 cl, 3 dwg |
