FIELD: mechanical engineering, particularly support metal structures used in air cooling plants. ^ SUBSTANCE: support structure comprises rod-like post members and cross-bars. The cross-bars form horizontal grid-like structure with three longitudinal and transversal belts creating support parts for heat-exchanging sections of gas air-cooling plant supporting. The grid-like structure also creates chambers for fans installation. The fans are mounted on support plates suspended by rigid braces forming four-disc three-dimensional system. The posts include posts of two kinds, namely intermediate and corner ones. Intermediate posts are flat V-shaped. Corner posts are three-dimensional and consist of vertical branches and two inclined branches adjoining lower part of vertical branch. The inclined branches are arranged in two mutually perpendicular planes. Intermediate post and corresponding parts of longitudinal belt form triangle so that distance between post branch ends corresponds to distance between adjacent support plates of chamber for fan installation. Angle between inclined and vertical branches of corner post is determined from a given relation. ^ EFFECT: reduced material consumption and labor inputs for support structure and support structure components erection. ^ 8 cl, 3 dwg |
