Prefabricated modular tower

Abstract

Prefabricated modular tower of the kind used as a support for wind generators and other applications, characterised in that it uses reduced-thickness prefabricated elements, reinforced with an internal structure of horizontal and vertical stiffeners, preferably made of reinforced concrete; said elements being tensioned both horizontally and vertically by means of flexible metal cables. The main advantages of the invention presented are that it enables fast construction of very high towers using a limited number of elements and that these elements are not heavy and are easy to transport, all of which leads to savings in manufacturing, transport and installation costs.

Description

technical field [0001] As the title indicates, this description relates to a prefabricated modular tower for use as a support for wind turbines and other equipment, characterized in that it uses prefabricated elements of reduced thickness, preferably made of reinforced concrete, utilizing horizontal and vertical stiffeners; said elements are tensioned horizontally and vertically by means of flexible metal cables. Background technique [0002] There are currently many types of generators driven by the wind, which are also called wind turbines. These generators consist of a turbine with attached blades, which is supported on a tower. [0003] Most of the more commonly used generator support towers are metallic and have either a lattice structure or a cylindrical or hollow conical shape. These types of towers have a series of problems, among which we will mention the need for frequent maintenance through anti-rust treatment or painting, due to material fatigue (because they h...

AI Technical Summary

Problems solved by technology

Given that the weight of these parts increases significantly, the same problem arises as forming the tower from a large number of parts, namely the high cost of both transport and assembly

Furthermore, in order to strengthen the structure of the tower, this embodiment employs an external pretensioning system comprising vertically tensioning cables, the problem of which is that it must be attached to the foundation of the tower, which must therefore be equipped with suitable anchors Another problem is that the cables are attached to the wall only at the through-holes of the flanges of said wall, which means only partial contact with the wall, so that the reinforcement is rather weak

In addition, most of the cables stay inside the tower, outside the walls and are exposed to the air, affecting visuals in addition to the stress on the cables and the degradation problems caused by atmospheric wear and erosion that seriously affect their service life
