SPATIAL REINFORCED CONCRETE FOUNDATION PLATFORM ON PERMAFROST SOIL

FIELD: construction.SUBSTANCE: invention relates to the field of construction, in particular, can be used in construction of a foundation of multi-storey buildings or structures, having the ability of natural ventilation and prevention of soil thawing in the permafrost zone. Spatial reinforced concrete foundation platform on permafrost contains interconnected upper and lower plates, which are connected by reinforced concrete trusses, diagonal or diagonal-free, or beams, between the trusses or beams crosswise links are installed in the transverse direction, and between the upper and lower plates a purged underground ventilated in all directions is formed. It is thermally regulated and comprises perimeter of enclosing wooden glued panels, forming with said reinforced concrete slabs closed space, wherein in all wooden glued panels installed with possibility of receiving wind currents and preventing snow transfer, built-in adjustable louvered grilles with electric drive. Spatial reinforced concrete foundation platform comprises a system for automatic control of the cooling process of the lower reinforced concrete slab and soil under it, including temperature sensors installed in the soil mass on the perimeter of the platform, ambient air temperature sensor, installed in bleeding underground, connected to sensors input device for conversion of analogue signal into digital, reprogrammable permanent storage unit (PROM) connected to input unit and output device for digital signal to analogue conversion, output device is connected with electric drive of adjustable louvered grids and with thermoelectric modules in form of battery of Peltier elements installed along perimeter on surface of lower reinforced concrete plate of foundation platform.EFFECT: technical result consists in improvement of efficiency of cooling of soils by providing direct cooling of lower reinforced concrete slab of spatial reinforced concrete foundation platform and prevention of snow transfer into blown underground.1 cl, 3 dwg Изобретение относится к области строительства, в частности может использоваться при устройстве фундамента многоэтажных зданий или сооружений, обладающего способностью естественного проветривания и предотвращения растепления грунта в зоне вечной мерзлоты. Пространственная железобетонная фундаментная платформа на вечномерзлом грунте содержит объединенные между собой верхние и нижние плиты, которые соединены железобетонными фермами, раскосными или безраскосными, или балкам
