The method for generating a substantially uninterrupted connection of the peripheral wall portions of two adjacent tubular segments each provided with flanges having holes therein, of a tower, in particular for a wind energy turbine, comprises the steps of: arranging a first tubular segment (18) and a second tubular segment (20) with said flanges (26, 28) thereof facing each other and said holes (34, 36) in said flanges (26, 28) aligned with each other; connecting said tubular segments (18, 20) by prefastening screws (38) extending through said aligned holes (34, 36) in said flanges (26, 28); forming into the side (50) of the tubular segments (18, 20) opposite to the flanges (26, 28) a notch (52) of a predetermined width at least at a location of said contacting flanges (26, 28) where a gap (48) having a width greater than a minimum width exists; inserting into said notch (52) at least one insert part (60) having a width substantially equal to the width of said notch (52); and completely fastening said screws (38) connecting said flanges 826, 28) of said tubular segments (18, 20) providing a substantially uninterrupted connection of said peripheral wall portions (22, 24) of said tubular segments (18, 20) through said at least one insert part (60).
La pr~sente invention concerne un proc~d~ permettant de r~aliser une liaison sensiblement ininterrompue entre des parties de parois p~riph~riques de deux segments tubulaires adjacents. Ces segments, qui sont destin~s notamment ~ la r~alisation d'un m~t d'~olienne, sont pourvus chacun de brides perc~es. Ce proc~d~ comporte plusieurs op~rations. On commence par aligner les deux segments tubulaires consid~r~s (18, 20) en pr~sentant les brides (26, 28) de fa×on ~ aligner les per×ages correspondants (34, 36). Pour relier ensuite les deux segments consid~r~s (18, 20), on passe dans les per×ages align~s (34, 36) des brides (26, 28) des vis (38) que l'on serre de fa×on provisoire. Sur le flanc (50) des segments tubulaires (18, 20), en regard des brides (26, 28), on r~alise une saign~e (52) d'une largeur d~finie, et ce, au moins en un endroit oÕ les brides (26, 28) au contact l'une de l'autre d~terminent un intervalle (48) d'une largeur sup~rieure ~ une largeur minimum. Dans cette saign~e (52), on insre au moins une pice rapport~e (60) d'une largeur sensiblement ~gale ~ celle de la saign~e (52). Il ne reste plus qu'~ finir le serrage des vis (38) de liaison des brides (26, 28) des segments tubulaires (18, 20), r~alisant ainsi au moyen d'au moins une pice rapport~e (60) une liaison sensiblement ininterrompue entre les parties de parois p~riph~riques consid~r~es (22, 24) desdits segments tubulaires (18, 20).
