FIELD: construction.SUBSTANCE: concrete unit 1 comprises a heat removal device made in the form of at least one coaxial pair of vertical pipes 2 and 3 connected to atmosphere. The outer pipe 2 of larger diameter (heat removal) is embedded into the concrete unit 1. The pipe 3 of smaller diameter is made as capable of dismantling and is portable. The upper edge of the inner pipe 3 is located above the upper edge of the outer pipe 2. In process of device operation, automatic heat removal is provided from the concreting unit 1 without human interference. Heat of exothermic reaction of hydration is carried through the outer pipe 2 by rising current 4 of air heated by concrete, and continuous inflow 5 of atmospheric air to the bottom of the heat removal pipe 2 is provided via the pipe 3 of smaller diameter coaxially arranged relative to the outer heat removal pipe.EFFECT: increased crack resistance of units for concreting of massive structures, simplified design of a device for heat removal from concrete.5 dwg |
