Description

ASSEMBLY METHOD FOR A TELESCOPIC TOWER AND MEANS FOR
IMPLEMENTING SAID METHOD
DESCRIPTION
FIELD OF THE INVENTION
The present invention relates to an assembly method for a telescopic tower and means for implementing said method, particularly a method and means for assembling a telescopic tower that includes at least one precast concrete segment, such as a telescopic tower of precast concrete segments meant to support a wind turbine.
Thus, the main field of application of the invention is the construction industry, particularly concrete construction, in combination with the industry of renewable or green power, specifically wind power. BACKGROUND OF THE INVENTION
In order to support a wind turbine at a great height, the use is known of towers made of at least two segments, including at least one precast concrete segment. It is also known that these segments can be modular, generally comprised of keystone shaped parts forming a tapering cylindrical segment. The total height of a tower is distributed among the various segments in any possible combination; all segments can have the same height, some can have the same height, all segments can have different heights, etc.
Recently, telescopic towers have been disclosed constituted by at least two coaxial segments with different diameters, optionally formed by keystone segments. These telescopic towers are assembled using a single support point in one segment to hoist another segment. For example, one method for assembling said telescopic towers is based on arranging, on one hand, cables or tendons that connect the top edge of each segment to the bottom edge of the radially internal and immediately adjacent segment, and on another hand traction means that act on said cables or tendons to rest on the top edge of an outer segment in assembled position and pull on the bottom edge of an inner segment in retracted position, thereby raising said inner segment to its assembled position and with it the set of internal segments interconnected with cables, and so on until all segments have been raised (see document WO 2011/006526 Al) .
However, the fact that one segment is raised by resting it on another segment imposes additional requirements on the segments, so that they can be used as supports during the raising.
DESCRIPTION OF THE INVENTION
For sake of simplicity, hereinafter the description will make reference to towers composed of said type of tapering cylindrical segments, in the understanding that the towers can also be composed of segments with oval, polygonal or any other appropriate shape. Also for sake of simplicity, hereinafter it is understood that the position of a segment is defined by the position of its axis of revolution, that is, that a segment will be in a vertical position if its axis of revolution is in a vertical position, that it will be in a horizontal position if its axis of rotation is in a horizontal position, etc.
One object of the invention is to provide a method for assembling a telescopic tower, specifically a method for assembling a telescopic tower that includes at least one precast concrete segment, such as a telescopic tower of precast concrete segments meant to support a wind turbine.
More specifically, the invention proposes an assembly method for a telescopic tower that comprises a base segment and at least one superposition segment, wherein the diameter of said base segment is larger than the diameter of said superposition segments, the assembly method comprising the following steps: a) arranging said segments in an initial position such that: the base segment is arranged vertically resting on an assembly surface, and said superposition segments are arranged coaxially inside said base segment, either resting on said assembly surface or separated from said assembly surface resting on a stationary support structure; b) arranging assembly means inside said base segment, said assembly means comprising: an upward pushing device that is not operationally applied on ay superposition segment, either resting on said assembly surface or separated from said assembly surface resting on a stationary support structure, and an application element that is radially expandable, that can be actuated by said pushing device so that it moves along a predetermined vertical path and is in the lowest position of said path when said assembly means are in a retracted condition; c) arranging said assembly means in said retracted condition and applying said application element to a lifting segment that is the innermost superposition segment of the superposition segments in an initial position, said application element being inscribed in the radially internal boundary of the immediately adjacent outer segment to said lifting segment; d) actuating said application element with said pushing device so that said application element rises and carries upward said lifting segment a predetermined distance that is equal to or less than said predetermined vertical path of said application element; e) joining at least provisionally said lifting segment to the immediately adjacent outer segment to said lifting segment ; f) optionally, repeating steps c) , d) , e) at least once.
Preferably, the predetermined vertical path of the application element is at least equal to the length of the longest segment of the tower; preferably, the application element carries upward each superposition segment until the bottom end of said superposition segment is essentially level with the upper end of the immediately adjacent outer segment; and preferably, each superposition segment carried upward until it bottom end is essentially level with the upper end of the immediately adjacent outer segment is at least provisionally joined by it bottom end to the upper end of the immediately adjacent outer segment. The predetermined vertical path of the application element can comprise a plurality of sub-paths. This is, the pushing device can comprise a pushing element with a predetermined vertical path shorter than the predetermined vertical path of the application element, and a lifting element that gradually lifts said pushing element at least until the elevation of the elevation element and the predetermined vertical path of the pushing element are equivalent to the predetermined vertical path of the application element. In this case, the pushing element opens until it reaches it predetermined vertical path, the lifting segment is provisionally anchored in a partially deployed position, the pushing element is retracted and therefore uncoupled from the lifting segment, the lifting element is lifted until the pushing element is again coupled to the lifting segment, and the pushing element is deployed again until reaching its predetermined vertical path, repeating these steps as many times as desired. The assembly method for a telecopic tower according to the present invention can be executed in inverse order (that is, performing the actions opposite to those described in each step and carrying out the steps essentially in the reverse order) in order to dismantle the telescopic tower.
Another object of the invention is to provide means for assembling a telescopic tower, specifically means for assembling a telescopic tower that include at least one precast concrete segment, such as a telescopic tower of precast concrete segments meant to support a wind turbine.
More specifically, the invention discloses means for assembling a telescopic tower that comprises a base segment and at least one superposition segment, wherein the diameter of said base segment is greater than the diameter of said superposition segments, said base segment resting vertically on an assembly surface, and said superposition segments being arranged coaxial to each other and with respect to said base segment, and said superposition segments being arranged in an initial operating position either resting on said assembly surface or separated from said assembly surface, resting on a stationary support structure; said assembly means comprising:
- an upward pushing device, that either rests on said assembly surface or is separated from said assembly surface resting on a stationary support structure; and
- an application element that can be actuated by said pushing device so that it can move along a predetermined vertical path, which is in the lowermost position of said path when said assembly means are in a retracted condition and which in the initial operating position with said assembly means in a retracted condition is applicable on the innermost superposition segment, said application element overcoming the immediately adjacent segment external to said innermost superposition segment and eventually said stationary support structures; these assembly means being placed inside said base segment, and said pushing device not being operationally coupled to any superposition segment, said application element being radially expandable so that it can be applied to at least one superposition segment different from said innermost superposition segment, overcoming both the immediately adjacent segment external to said at least one superposition segment different from said innermost superposition segment as well as eventually said stationary support structures.
Said support stationary structure for said superposition segments and said stationary support structure for said assembly means can be the same or different. In any case these structures may rest on said assembly surface or on the base segment .
In the case of the support structure for superposition segments, this structure can also rest partially on other superposition segments. For example, the support structure for superposition segments may comprise an anchoring for the outermost superposition segment with respect to the base segment, an anchoring for the next superposition segment after the outermost superposition segment, and so on to the innermost superposition segment.
