ABSTRACT:
Supporting structure for a large natural draft cooling tower consisting of a central tower support in the form of a hollow column of reinforced concrete and hyperboloid-shaped cooling tower mantle supported by the central tower support with the aid of cables and tie rings at the top and bottom of the cooling tower mantle. The upper tie ring is suspended from the top of the central tower support by means of a series of inclined supporting cables and the lower tie ring is connected to the upper tie ring by means of two sets of oppositely diagonally inclined mantle supporting cables, under a downwardly directed preload, forming a hyperboloid-shaped cable grid. To this grid are attached the section panels of the cooling tower mantle. The cable preload is provided by means of holding cables extending between the lower tie ring and a series of ground anchors, or by means of the diagonally inclined cables themselves which may be attached to the ground anchors. The mantle supporting cables may include a third set of cables in a meridian arrangement or in a concentric circular arrangement. The inclined supporting cables of the upper tie ring carry wind deflector rings.
