Structure and procedure for erecting concrete towers used in wind turbines in which said towers consist of sections, which in turn may each comprise a different number of segments or longitudinal sections. The procedure includes two differentiated cycles, which may take place alongside each other: the pre-assembly of each section of tower and their assembly. The sections may be pre-mounted on bases placed on the ground, with the segment in turn fitted with the help of struts and mechanical clamps. This procedure is extremely versatile in that it makes the best logistic use of the material, resources and requisite assembly times since the assembly procedures for each section can be developed alongside each other in the different wind farm towers, and also greater heights can be achieved than is traditionally possible.

1. A method for erecting a plurality of concrete towers for wind turbines in a wind farm, wherein each tower comprises a concrete base section and at least one concrete upper section, at least some of said sections further comprising longitudinal segments, the method comprising: for each tower in the plurality of towers, performing a pre-assembly cycle further comprising erecting and connecting a first plurality of longitudinal segments on a base footing to form a base section for the tower, the erecting and connecting the first plurality of longitudinal segments further comprising placing each one of the first plurality longitudinal segments vertically on the base footing;connecting the base section to the base footing of the tower;erecting and connecting a second plurality of longitudinal segments on an assembly base provided on the ground in proximity to the corresponding base section to form an upper section for the tower, the erecting and connecting the second plurality of longitudinal segments further comprising placing each one of the second plurality of longitudinal segments vertically on the assembly base;for each tower in the plurality of towers, performing an erection cycle further comprising after the second plurality of longitudinal segments is connected to form the upper section, placing the erected upper section on top of the corresponding base section;wherein the pre-assembly cycle and the erection cycle are performed at the same time for different towers in the wind farm and the pre-assembly cycle for a first tower begins before the beginning of the pre-assembly cycle for a second tower, and the erection cycle for the first tower begins after the beginning of the pre-assembly cycle for the second tower. 2. The method of claim 1, wherein the erection cycle for the first tower begins after the end of the pre-assembly cycle for the second tower. 3. The method of claim 1, wherein the pre-assembly cycle for a tower begins at least some weeks before the erection cycle for the same tower. 4. The method of claim 1, further comprising: providing equipment for the erection of the plurality of towers so that equipment for performing the pre-assembly cycle has a productive capacity approximately the same as the equipment provided for performing the erection cycle. 5. The method of claim 4, wherein the equipment provided for the erection of the plurality of towers has a productive capacity of two towers per week. 6. The method of claim 1, wherein the pre-assembly cycle is always at least one tower ahead of the erection cycle, interference between the cycles being thus avoided. 7. The method of claim 1, wherein the erection cycle is performed using a crane. 8. The method of claim 7, the erected upper section is moved directly from the assembly base to the top of the corresponding base section by crane. 9. The method of claim 8, wherein a single high capacity crane is used to place the upper section on the corresponding base section for each of the towers in the plurality of towers, so that only a single high capacity crane is required to erect the wind farm. 10. The method of claim 1, wherein longitudinal segments are connected by filling vertical joints therebetween with mortar. 11. The method of claim 1, wherein erecting the longitudinal segments includes providing a temporary support for at least one of said segments. 12. The method of claim 11, wherein the temporary support comprises struts. 13. The method of claim 1, wherein placing the erected sections on top of the base sections further comprises inserting passive bars from the upper sections into corresponding openings of the base sections. 14. The method of claim 13, which further comprises pouring mortar into the openings of the base sections. 15. The method of claim 1, wherein the erection cycle for a first tower begins after the beginning of the pre-assembly cycle for said first tower and after the beginning of the pre-assembly cycle for a second tower. 16. The method of claim 1, wherein the first plurality of longitudinal segments are reinforced concrete longitudinal segments. 17. The method of claim 1, wherein the second plurality of longitudinal segments are reinforced concrete longitudinal segments. 18. A method for erecting a plurality of concrete towers for wind turbines in a wind farm, wherein each tower comprises a concrete base section and at least one concrete upper section, at least some of said sections further comprising longitudinal segments, the method comprising: for each tower in the plurality of towers erecting and connecting a first plurality of longitudinal segments on a base footing to form a base section for the tower, wherein the erecting and connecting the first plurality of longitudinal segments further comprises placing each one of the first plurality longitudinal segments vertically on the base footing;connecting the base section to the base footing of the tower;erecting and connecting a second plurality of longitudinal segments on an assembly base provided on the ground in the proximity to the corresponding base section to form an upper section for the tower, wherein the erecting and connecting the second plurality of longitudinal segments further comprises placing each one of the second plurality of longitudinal segments vertically on the assembly base;after the second plurality of longitudinal segments is connected to form the upper section, placing the erected upper section on top of the corresponding base section;wherein at least some of the upper sections of the plurality of towers are placed before all of the lower sections for other towers have been erected and connected and for a first group of towers, the placing of erected upper sections on top of the corresponding base sections starts after starting the forming of base sections for a second group of towers but before the erected upper sections of the second group of towers are placed on the corresponding base sections of the second group of towers. 19. The method of claim 18, further comprising: starting the forming of base sections of a subset of the plurality of towers; andbefore any upper sections of any towers in the subset of the plurality of towers are placed on top of the corresponding base sections, starting the forming of upper sections of a subset of the plurality of towers. 20. The method of claim 18, wherein longitudinal segments are connected by filling vertical joints therebetween with mortar. 21. The method of claim 18, wherein the first plurality of longitudinal segments are reinforced concrete longitudinal segments. 22. The method of claim 18, wherein the second plurality of longitudinal segments are reinforced concrete longitudinal segments. 23. The method of claim 18, wherein the erected upper section is moved directly from the assembly base to the top of the corresponding base section by crane. 24. The method of claim 23, wherein a single high capacity crane is used to place the upper section on the corresponding base section for each of the towers in the plurality of towers, so that only a single high capacity crane is required to erect the wind farm.
