Abstract

EN In terms of building physics, the building rounded corner is a thermally conductive inclusion. The corner heat-protective properties are less than the flat wall. This is explained by the fact that the heat perception area (inner surface) of the corner is less than the heat transfer area (outer surface). While on a flat wall these areas are the same. Also in the corner there is a decrease in the temperature of the inner surface due to the convective component of the heat flux reduction. The reduction of this flow is due to the air flow inhibition in its inner surface. If the surface temperature is below the dew point, condensation will form on it. The article analyzes and obtains equations for the relationship between insulation thermal conductivity, which ensures compliance with thermal protection, its thickness and rounding radius of the outer wall for brick walls with a thickness of 0.51 m, 0.38 m and 0.25 m insulated from the outside. To ensure the thermal protection norms, it is necessary that the accepted insulation thermal conductivity was not more than, and the insulation thickness and the wall rounding radius is not less than calculated by the equations.
