Problems solved by technology

An additional drawback is that concrete is typically heavier, about 4 to 5 times heavier than steel towers, which requires the construction of heavy foundations to support the tower

Embodiment Construction

[0065] The present invention provides an apparatus, composite section and method for in situ tower formation that overcomes the deficiencies in the prior art. The devices, composite sections and methods provide a cost-effective and easily transportable means for on-site tower assembly.

[0066] figure 1 Shown is the use of the apparatus 500 described in the present invention (see for example Figure 5 ), composite section 120, and method-formed tower 104 embodiments. The tower 104 (the wind turbine tower) includes housing for the generator (not in figure 1 The nacelle 102 shown in ). The height of tower 104 is selected based on factors and conditions known in the art, and may extend to heights of up to 100 meters or more. Wind turbine 100 may be installed on any terrain that provides access to areas with ideal wind conditions. Terrain can vary widely and can include, but is not limited to, mountainous terrain or maritime locations. Wind turbine 100 also includes a rotor ...

Abstract

A composite section including a concentric arrangement of inner and outer laminates having an interstice therebetween is provided. Both the inner and outer laminates include a matrix material and a fabric layer. A plurality of tubes having an inner cavity, are situated in the interstice of the inner and outer laminates. A reinforcing material is disposed in the interstice and along the length of the concentric arrangement unoccupied by the plurality of tubes to create a composite section. A plurality of tension members are threaded though the plurality of tubes to provide post tensioning to each of the composite sections. The components are easily transported and assembled to form composite sections to provide cost effective on-site tower formation. Also provided is an apparatus to form the inner and outer laminates and a method of formation of the composite section.

Description

technical field [0001] The present invention relates generally to towers, and more particularly to apparatus, methods and composite sections that allow towers to be formed in situ. Background technique [0002] Large wind turbines are getting taller. However, beyond a certain height, standard steel tube towers have proven uneconomical, ie the cost of constructing the additional height will outweigh the benefits of better wind conditions at higher altitudes. This has prompted the search for alternative tower technologies to achieve greater tower heights. [0003] Modular or formwork concrete towers have become a new trend in the wind turbine tower industry due to low material costs and on-site / local fabrication potential. Although concrete is known to be a good choice for compression, concrete requires specific treatment to resist tension. Typically rebar and post tensioned wire cables are used to strengthen the concrete. Furthermore, in order to meet the necessary tolera...
