FIELD: construction industry.
SUBSTANCE: hydraulic heat insulation of underground construction consists of metal sheets welded together and installed at a distance from reinforced-concrete enclosure structures and attached to these structures with anchors and mounting flanges. Layer of hydraulic heat-insulating material being more preferable for certain conditions is applied to enclosure structures. Metal sheets are made from Duralumin 1-3 mm thick and form the screen covering upper part of construction shape. Tubular radiators located in the space between hydraulic heat-insulating layer and screen on the screen ends throughout its length are fixed tightly on screen inner surface. Tubular radiators form series circuit, input and output of which is attached either to heating system return line from boiler house during winter season, or to hot-water supply system during summer season. Anchors are designed so that tubular radiators can be attached to them and flanges can be held down to screen sheets with nuts.
EFFECT: protecting the construction from condensate formed from ventilation air.
