example 1
[0025] Example 1 – Erection by means of temporary lifting structures
[0026] In the first embodiment of the present invention ( Figure 1-7 shown in ), first build the main structure 1 ( figure 1 ), after which one or more temporary lifting structures including lifting towers 13a are installed next to the main structure 1; strand jacks 7 are preferably provided on the lifting towers 13a and the main structure 1, and modules 3 ready for installation are provided ( figure 2 ).
[0027] The module 3a is thus preferably placed in its final footprint 9 ( image 3 ), and it is raised by a strand jack 7 of height H, which is large enough to allow the additional module 3b to be positioned below module 3a ( Figure 4 ).
[0028] The additional module 3b is thus provided and the module 3a is positioned on top of the additional module 3b (thereby the additional module 3b is positioned below the module 3a, preferably in its final footprint 9); the module 3a and the additional modu...

[0035] Example 2 – Erection by means of temporary lifting structures including bridges
[0036] In the second embodiment of the present invention ( Figure 8-16 shown in ), first build the main structure 1 ( Figure 8 ); then build one or more temporary elevating structures next to the main structure 1 and connect them to the main structure 1 ( Figure 9 ).
[0037] The temporary lifting structure comprises a lifting tower 13a and a bridge 13b connecting the lifting tower 13a to the main structure 1 . On top of the bridge 13b, a carrier 14 with a strand jack 7 is provided.
[0038] Provides ready-to-install modules 3 ( Figure 10 ), then module 3a is preferably provided in its final footprint ( Figure 11 ).
[0039] The additional module 3b is then provided next to the module 3a and it is raised by the strand jack 7 ( Figure 12 ), move it by the carrier 14 ( Figure 13 ), and thus connect the additional module 3b to the top of the module 3a ( Figure 14 ) to define ...
