Building cradle member for support panel receiving define a circle in plane and has at least one horizontal support-and-guiding surface. Building cradle members for support and connection plates are mainly formed as prisms having trapezoid cross-sections with at least outer inclined face forming support-and-guiding surface to receive support and connection plates of central support member for fan engine installation.
EFFECT: increased manufacturability of gas air-cooling plant production, simplified assemblage, reduced costs and increased reliability and service life of structure to be produced.
