FIELD: construction. ^ SUBSTANCE: coupling of ventilation units through the opening in the floor panel of the building contains ventilation openings. Size of the sides of the opening in the floor panel between ventilation units is smaller than size of the lateral walls of ventilation units by width of the walls, coupling is equipped with cases according to the number of the openings of the ventilation unit, thereat each of the cases is made free of front walls, and lateral walls of each of the case are connected with corresponding openings of ventilation cases so that, walls of each of the cases in the bottom part are arranged in the corresponding openings of the lower ventilation unit under the floor panel and are adjacent to the walls of the opening of the ventilation unit, and in the upper part of each of the cases at the level of the top surface of the floor panel walls of the case are unbent to the outside by the value equal to the thickness of the walls and seals between the openings of the ventilation unit at a straight angle, whereat gaps between cases are filled with concrete at the thickness of the floor panel, and seams between the panel and the lower ventilation unit are filled with elastic material, for example, construction foam. ^ EFFECT: simplification of the design, ease of assembly, enhanced hermiticity and reliability of connection. ^ 1 dwg |
