FIELD: building industry branches, namely apparatuses for heat treatment of constructions of reinforced concrete erected in building site with use of automatic control of heat treatment processes. ^ SUBSTANCE: apparatus includes concrete form having electric heating units mounted in its boards for convection-irradiation heating of concrete mixture and heating members mounted in bottom of concrete form for convection-irradiation heating; temperature pickups having individual control circuits and connected to inlets of heat regulators. Outlets of heat regulators are connected through switching units having magnetic starters with respective electric heating units. Each control circuit includes at least six temperature pickups placed in monolithic construction and pickup for measuring temperature of environmental air. Said pickups are connected with inlets of respective programmed heat regulator for supplying control signals. ^ EFFECT: enhanced quality of constructions. ^ 3 cl, 4 dwg |
