FIELD: construction.
SUBSTANCE: construction of horizontal monolithic concrete and reinforced concrete structures, hydraulic engineering and land reclamation structures, as well as for heating frozen soils. A device for heat treatment of horizontal monolithic concrete and reinforced concrete structures contains a housing, a centrifugal fan of the device driving warm air, located in the device housing and equipped with a speed controller and an electric motor, an electric heater located along the perimeter of the inner part of the housing, between the fan and the housing wall. In this case, the housing in the lower part is connected to the inlet pipe, located along the lower circle of the housing and equipped with a metal mesh or grille to protect against foreign objects. The upper part of the body is equipped with a spherical head.
EFFECT: improved efficiency of heating concrete by air convective heating due to forced mixing of warm air in the heated space, reduced energy costs through reduction in the volume of heated air space, and reduced heat loss to the environment.
