201124618 六、發明說明： 【發明所屬之技術領域】 本發明是關於單柱式塔柱以及具備單柱式塔柱（支柱 )的風力發電裝置。 【先前技術】 風力發電裝置係由具備風車葉片的轉子頭承受風力而 進行旋轉’並將這個旋轉藉由加速機予以加速來驅動發電 機以進行發電的裝置。 上述的轉子頭係安裝在設於風車用塔柱（以下稱塔柱 )上之可轉向迴旋的機艙的端部，且被支承可在略水平的 横方向的旋轉軸線外圍進行旋轉。 一般而言，上述風車用塔柱採用：使用了圓筒形狀的 殼體之鋼製單柱式的情況很多，其構造爲：將設在塔柱殼 體的下端部的底座板利用地錨螺栓固定在由鋼筋混凝土構 成的基礎上。 第11圖以及第12圖係顯示傳統的塔柱支承構造，在塔 柱2的下端部，設置著從塔柱殼體21的内外兩面朝水平方 向突出的凸緣狀的底座板22。這個底座板2 2係利用許多根 將其下端部側埋設在基礎B內的地錨螺栓1 0，以將塔柱2連 結固定於基礎B上的構件。圖示的構造例中，係在圓筒形 狀的塔柱殼體2 1的外周側以及内周側，在同心圓上上排列 兩排地錨螺栓10，在貫穿過底座板22的螺栓孔22A之後的 各個地錨螺栓10的上端部側將螺帽11螺合於該處’以便將 201124618 各個地錨螺栓1 0予以固定。此外，圖中的元件符號1 2係形 成在基礎Β的混凝土上的水泥層。 又，有人針對鋼骨柱與鋼骨樑的榫接組合構造，提出 一種方案係只要藉由樑的稍微移動即可很容易獲得其與固 定托架之間的間隙，而無需使用微動的吊車操作、輔助用 的重機械等來進行調整。這種榫接組合構造，係將鋼骨柱 的固定托架與鋼骨樑兩者，都以朝鍵入側（榫頭側）開放 的形狀加以切斷，再抵接一個加添接板之後，利用高張力 螺栓加以鎖緊締結而構成榫接組合構造。（請參考例如： 專利文獻1 ) [專利文獻1]日本特開平7-20783 3號公報 【發明內容】 然而，上述傳統的塔柱支承構造係將地錨螺栓10配置 於塔柱殼體2 1的外側才可獲得較佳的作用效果，因此，底 座凸緣大多突出於塔柱殼體21的外側。再者，做成圓筒形 狀的鋼製殼體構件係爲主要的強度構件，所以塔柱殼體2 1 的外徑做得愈大其斷面積效率較佳，因此鋼製的單柱式塔 柱係在可謀求最少重量的範圍內，儘可能加大殼體的外徑 爲佳。 另一方面，塔柱2的外形尺寸也必須符合在輸送時等 各種情況下所產生的限制條件。上述的單柱式塔柱的情況 ’雖然是將塔柱2在其高度方向上分割製作成複數個區段 之後才進行輸送的，但是單就基部的塔柱區段而言，則是 -6- 201124618 將底座板22焊接在塔柱殼體21以使兩者形成一體化的狀態 下進行輸送。因此’從塔柱殻體2 1朝往外側突伸出去的底 座板22的外徑就成爲塔柱2的最大外徑，因此很難將塔柱 殻體2 1的外徑製作成小於等於限制條件的大小。 本發明係有鑒於前述的情事而開發完成的，其目的係 在於提供：一種風力發電裝置，係採用塔柱支承構造，藉 由取消較之塔柱殼體朝往外側突伸出去的底座板，而使得 塔柱殼體的外形尺寸就成爲其最大外徑。 本發明爲了解決前述的課題，採用了下列手段。 本發明的申請專利範圍第1項的單柱式塔柱，係豎立 設置於基礎上的單柱式塔柱，其特徵爲： 前述塔柱的下端部側，在小於或等於塔柱殼體的外徑 的範圍內係具備塔柱側連結構件，在具有設在前述基礎上 的基礎側連結構件的空間內，前述基礎側連結構件與前述 塔柱側連結構件係藉由焊接或藉由使用了加添接板的螺栓 或鉚釘而連結在一起》 根據申請專利範圍第1項所述的單柱式塔柱，因爲塔 柱的下端部側係在小於或等於塔柱殼體的外徑的範圍內係 具備塔柱側連結構件，在具有設在前述基礎上的基礎側連 結構件的空間內，前述基礎側連結構件與前述塔柱側連結 構件係藉由焊接或藉由使用了加添接板的螺栓或鉚釘而連 結在一起，所以不再有例如：底座板的這種較之塔柱殼體 的外徑更大的構件存在，因此，可將塔柱殼體的外徑製作 成在限制條件下的最大外徑，從而得以提高斷面積效率。 201124618 亦即，就塔柱外徑尺寸而言，可將塔柱殼體的外徑當作最 大外徑。 針對於申請專利範圍第1項所述的單柱式塔柱，其中 ，前述塔柱的下端部側係具備有：由塔柱殼體以及内筒所 組成的雙重管構造部，並且將延長至前述基礎内部爲止的 前述内筒與前述塔柱側連結構件都***到前述空間爲宜。 本發明的申請專利範圍第3項的單柱式塔柱，係豎立 設置於鋼筋混凝土製的基礎上的單柱式塔柱，其特徵爲： 在前述塔柱的下端部側形成一基礎結合部，該基礎結 合部係具備：設置在前述塔柱内部的下端部旁邊的隔板； 被結合在該隔板的下面而將塔柱殼體的内部往下方延伸直 到前述基礎内部爲止的内筒；被安裝在該内筒的下端部之 與前述塔柱殼體的外徑大致同一外徑的底板；被與前述塔 柱殼體的内面、前述隔板的下面、前述内筒的外面、前述 底板的上面相結合，並且在從前述内筒的外周面起算至小 於等於塔柱殼體的外徑的範圍內，呈放射狀配設的塔柱側 托架；用來將前述塔柱殻體的下端部與前述内筒的外周面 以及前述塔柱側托架予以相連結的環型隔板所構成的， 在前述基礎的中央部形成一塔柱結合空間部，該塔柱 結合空間部係具備：供前述基礎結合部***的基礎空間部 :被固定在基礎上，是以與前述塔柱側托架互相牽合的方 式配置於前述塔柱側托架的延長線上，且露出在前述基礎 空間部的基礎側托架所構成的， 將前述基礎結合部***到前述塔柱結合空間部，將前 -8- 201124618 述基礎結合部側的連結構件與前述基礎側托架之間’藉由 加添接板來予以連結在一起’或者利用焊接來予以連結在 —起。 根據申請專利範圍第3項所述的單柱式塔柱’在前述 塔柱的下端部側形成一基礎結合部’該基礎結合部係具備 :設置在前述塔柱内部的下端部旁邊的隔板；被結合在該 隔板的下面而將塔柱殼體的内部往下方延伸直到前述基礎 内部爲止的内筒；被安裝在該内筒的下端部之與前述塔柱 殻體的外徑大致同一外徑的底板；被與前述塔柱殼體的内 面、前述隔板的下面、前述内筒的外面、前述底板的上面 相結合，並且在從前述内筒的外周面起算至小於等於塔柱 殼體的外徑的範圍內，呈放射狀配設的塔柱側托架；用來 將前述塔柱殼體的下端部與前述内筒的外周面以及前述塔 柱側托架予以相連結的環型隔板所構成的， 在前述基礎的中央部形成一塔柱結合空間部，該塔柱 結合空間部係具備：供前述基礎結合部***的基礎空間部 :被固定在基礎上，是以與前述塔柱側托架互相牽合的方 式配置於前述塔柱側托架的延長線上，且露出在前述基礎 空間部的基礎側托架所構成的， 將前述基礎結合部***到前述塔柱結合空間部，將前 述基礎結合部側的連結構件與前述基礎側托架之間，藉由 加添接板來予以連結在一起’或者利用焊接來予以連結在 一起’所以不再有例如：底座板的這種較之塔柱殼體的外 徑更大的構件存在’因此，可將塔柱殼體的外徑製作成在 -9 - 201124618 限制條件下的最大外徑，從而得以提高斷面積效率。亦即 ，就塔柱外徑尺寸而言，可將塔柱殻體的外徑當作最大外 徑。 針對於申請專利範圍第3項所述的單柱式塔柱，其中 ，前述基礎側托架係製作成在上下設有凸緣部之I形斷面 形狀，除了在前述塔柱側托架以及前述基礎側托架的縱壁 彼此之間之外，在前述環型隔板以及前述底板與前述凸緣 部之間，係使用前述加添接板以及螺栓暨螺帽來予以連結 在一起或者藉由焊接來予以連結在一起爲宜。如此一來， 可更加提昇塔柱與基礎的連結強度。 在前述的發明中，設置在前述塔柱的下端部旁邊的前 述隔板係位於設在前述塔柱殻體上的門扉開口部的下側旁 邊爲佳，如此一來，可將隔板兼用作爲：設在進入塔柱内 部之入口部的地板》 在前述的發明中，前述内筒係製作成：以大徑側的上 端部結合到前述塔柱殼體的圓錐台形狀爲佳，如此一來， 從塔柱殼體傳導到内筒的應力傳遞可更爲平順，因此從塔 柱傳導到基礎的應力傳遞也變平順》 在前述的發明中，係在前述塔柱結合空間部，將前述 基礎結合部側的連結部構件與前述基礎側托架相連結之後 ，再充塡混凝土爲佳。 本發明的申請專利範圍第8項所述的風力發電裝置， 係以具備如申請專利範圍第1項或第3項所述的單柱式塔柱 爲其特徵。 -10- 201124618 根據這種風力發電裝置，因爲是具備如申請專利範圍 第1項或第3項所述的單柱式塔柱，所以就塔柱外徑尺寸而 言，塔柱殼體的外徑就成爲其最大外徑。 根據上述本發明的單柱式塔柱以及風力發電裝置’因 爲是可將塔柱殻體的外徑當作塔柱的最大外徑，換言之， 不再需要有例如：底座板的這種會往塔柱殼體的外側突出 的構件，因此可將塔柱殼體的外徑予以加大到最大限度而 可提昇斷面稹效率，並且可達成：在輸送等的限制條件下 的範圍内，儘量地製作成最大外徑的塔柱支承構造。亦即 ，在具備單柱式塔柱的風力發電裝置中，藉由採用本發明 的塔柱支承構造的話，即可將塔柱殼體的外形尺寸當作其 最大外徑。 其結果，可獲得一種塔柱支承構造的風力發電裝置， 該風力發電裝置係就隨著風力發電裝置的大型化而變得更 高且荷重條件也趨於更嚴格的塔柱而言，可很容易兼具： 既符合輸送限界等的限制條件又同時確保所需的強度之兩 種條件。 此外，托架、加添接板等係可使用低價的輥軋鋼板， 而且不必再使用昂貴的底座凸緣、地錨螺栓，所以可達成 風力發電裝置的低成本化。再者，因爲不再使用地錨螺栓 ，所以也無需再執行例如：鎖緊螺帽等的維護保養工作了 【實施方式】 -11 -

According to the single-column tower and the wind power generator of the present invention described above, since the outer diameter of the tower casing can be regarded as the maximum outer diameter of the tower column, in other words, such a portion of the base plate is no longer required. The protruding member on the outer side of the column housing can increase the outer diameter of the column housing to the maximum extent and improve the efficiency of the section ,, and can be achieved within the limits of transportation and the like, The column support structure of the largest outer diameter is produced. That is, in the wind power generator having the single-column column, by adopting the column support structure of the present invention, the outer dimensions of the column case can be regarded as the maximum outer diameter. As a result, a wind power generation device having a column support structure can be obtained, and the wind power generation device can be made higher as the size of the wind power generation device becomes larger and the load conditions tend to be more stringent. It is easy to combine: Two conditions that meet the constraints of the transport limit and the like while ensuring the required strength. Further, since a low-cost rolled steel plate can be used for the bracket, the additional plate, and the like, and it is not necessary to use an expensive base flange or a ground anchor bolt, the cost of the wind power generator can be reduced. Furthermore, since the ground anchor bolt is no longer used, it is not necessary to perform maintenance work such as a lock nut or the like.

A plurality of column side brackets 35 are radially arranged from the outer peripheral surface of the inner cylinder 32. The partition plate 31 is a circular plate material having the same diameter as the inner diameter of the column 2 . This partition plate 3 1 is attached to the inner wall of the column housing 2 by welding to divide the internal space of the column -13 - 201124618 2 into upper and lower spaces. Further, the partition plate 31 is attached to the sill opening portion 6 provided in the column housing 21 at a position which is located beside the lower end portion of the column 2, that is, it is attached to: At the side of the lower side of the sill opening portion 6 of the column housing 21, it can also be used as the inner floor material of the column 2, and the sill opening portion 6 is used for construction and maintenance work. An opening that can be opened and closed is attached to the opening when the inside of the column 2 is moved in and out. The inner cylinder 32 is a concentric cylindrical member disposed in the inner space of the column casing 21, and the upper end of the cylinder is welded to the lower surface of the partition plate 31. The lower end portion of the inner cylinder 32 is extended downward from the lower end portion of the column casing 21, and the lower end portion is inserted into the interior of the foundation B at a predetermined installation position. The bottom plate 33 is a circular or polygonal plate material that is welded to the lower end portion of the inner cylinder 32. This bottom plate 3 3 is substantially the same diameter as the outer diameter of the column housing 21, and is supported by the concrete installation surface formed in the column-joining space portion 50 after the filled concrete is hardened. Further, this bottom plate 33 is also used as a connecting member on the side of the base joint portion 30. The ring-shaped partition plate 34 is an annular plate-like member for connecting the lower end portion of the column casing 21 to the outer peripheral surface of the inner cylinder 32 and the side surface of the column-side bracket 35. This annular spacer 34 is formed at the position of the bracket 35 on the column side, and is divided into an arc shape in the circumferential direction, and the inner peripheral end thereof is welded to the outer peripheral surface of the inner cylinder 32, and the outer peripheral end is welded to the column case. The lower end portion of the body 21 is welded to the side surface of the bracket 35 on the column side in the circumferential direction. -14- 201124618 The column side bracket 35 is welded to the outer surface of the inner cylinder 32, the inner surface of the column housing 21, the bottom surface of the partition plate 31, and the rectangular plate-like member on the upper surface of the bottom plate 33. The outer peripheral surface of 32 is radially disposed in a radial region up to the outer circumference of the column housing 21, and a plurality of them are radially arranged. In the illustrated configuration example, eight column-side brackets 35 are radially provided from the outer circumferential surface of the inner cylinder 3 2 at a pitch of 45 degrees in the circumferential direction. The column-side brackets 35 are used as the main connecting members on the side of the base joint portion 30. Further, the number of the brackets 35 on the column side can be appropriately changed in accordance with various conditions. Therefore, it is not limited to the above eight. The above-described column-column joint portion 50 is formed at the center portion of the base B. The column-column joint portion 50 is formed with a base space portion 52 which is not filled with concrete, and the base-side bracket 51 is integrally formed with the base B so as to be exposed to the base space portion 52. The base side bracket 51 shown in the drawing is a member having an I-shaped cross-sectional shape in which the flange portions 51a and 51b are provided on the upper and lower sides as shown in Fig. 5 . In this case, the base side bracket 51 is disposed on the extension line of the tray-side bracket 35 in such a manner as to be engaged with the column-side bracket 35. In other words, the eight column-side brackets 35 arranged radially are attached to each other at a predetermined column-column position so as to be radially attached at a pitch of 45 degrees in the circumferential direction. As a result, at the predetermined column arrangement position, the column side bracket 35 and the base side bracket 51 are present on the same straight line in a radial direction. When the column 2 is placed on the base B and fixed, the base joint portion 30 is inserted into the column joint space portion 50, and the column side bracket 35 and the bottom plate 33 which are the joint members on the base joint portion 30 side and Between the annular spacer 34 and the base -15-201124618 side bracket 51, the joint plate 60 and the bolt and nut 7 are joined together. The additional contact plate 60 is a plate-shaped member that spans the connection member disposed on the side of the base joint portion 30 and the connection member on the side of the column-joining space portion 50, and is configured to sandwich the two members from the two bread clips. On both sides. And a plurality of sets of bolts and nuts 70 extending through the joint member and the additional joints 60 disposed on both sides thereof are used, and the three pieces of the members are tightly joined by the sets of bolts and nuts 70. The base joint portion 30 and the joint members of the column joint space portion 50 are firmly coupled to each other. Further, as a connection between the column-side bracket 35, the bottom plate 33, and the ring-shaped partition plate 34 of the connecting member on the base joint portion 30 side and the base-side bracket 51, in the above-described method, for example, Bolts and nuts are made of high-tension bolts and nuts; friction-joined structures; structures that are joined by rivets; or in various structures that use welded joints, etc., without the use of additional joints and bolts and nuts. Make the right choice. 4A is a view in which the C portion of FIG. 1A is enlarged, and the flange portion 51a provided on the upper portion of the base side bracket 51 and the annular spacer 34 on the column side are subjected to the upper and lower sheets. With the holding of the plate 60, the three plate-like members are tightly joined together by a plurality of sets of bolts and nuts 70. Further, a through hole 23 is formed in the column casing 21, and the additional plate 60 is inserted into the inside and the outside of the column 2. In addition, FIG. 4B is a view in which the D portion of FIG. 1A is enlarged, and the flange portion 51b provided at the lower portion of the base side bracket 51 and the bottom plate 33 on the column side are subjected to the upper and lower sheets. The holding of the plate 60, the three plate-like members are closely joined together by a plurality of bolts and nuts 70 of the 2011-201124618 group. Further, the fifth drawing is an EE sectional view of the second drawing, which is set in an I shape. The upper and lower flange portions 51a and 5 lb of the base side bracket 51 of the cross section are coupled to both sides of the vertical wall portion and the vertical wall portion, and are connected to the horizontal direction by the joining material 60 and the bolt and nut 70. Ring spacer 34 or bottom plate 33. In this case, the connecting portion between the vertical wall portion and the vertical wall portion connects the column-side bracket 35 and the base-side bracket 51 that are arranged in the vertical direction by the joining material 60 and the bolt and nut 70. After the part. In this manner, if the base side bracket 51 has an I-shaped cross-sectional shape in which the flange portions 5 1 a and 5 1 b are provided on the upper and lower sides, not only the column-side bracket 35 but also the base-side bracket 5 1 Between the vertical wall portions, the annular spacer 34 and the bottom plate 35 and the flange portions 51a and 51b may be joined together by the additional plate 60 and the bolt and nut 70. As a result, the base joint portion 30 and the base B are firmly joined together in both the vertical direction and the horizontal direction, so that the joint strength between the tower column 2 and the base B can be further improved. In the embodiment, the connection member on the side of the base coupling portion 30 is coupled to the base side bracket 5 1 of the column joint space portion 50, and then the concrete is filled into the column joint space portion 50. Then, after the concrete in the column-combining space portion 50 is hardened, the column support structure in which the column 2 is erected on the foundation B is completed. In addition, when the tower 2 is to be erected on the foundation B, the lowermost column section provided with the basic joint 30 is first erected after the foundation B, and then the upper tower section is sequentially connected. Then complete the single column column 2 of the required height. -17- 201124618 The column support structure constructed in this way, since there is no need to use the base plate 22 having the largest outer diameter in the conventional column structure, there is no member larger than the outer diameter of the column case 21 . Therefore, when the design of the column 2 is performed, the outer diameter of the column housing 21 can be set to a limit condition that can meet the transportation limit, etc., so that the outer diameter of the column housing 21 can be expanded until the restriction condition is reached. The size of the area can thus increase the efficiency of the area. That is, the outer diameter of the column 2 can be regarded as the maximum outer diameter of the outer diameter of the column housing 21. However, based on the consideration of the weldability between the lifting column housing 21 and the annular spacer 34, it is also conceivable to make the outer diameter of the annular spacer 34 slightly larger than the outer diameter of the column housing 21. . Further, the lower end portion of the column 2 is formed in a double pipe structure of the column casing 21 and the inner cylinder 32 in a region further below the partition plate 31. Therefore, the strength of the lower end side of the root portion of the column 2 can be increased, and the thickness of the column housing 21 can be reduced by the double structure portion. Further, by providing the partition plate 3 1 beside the lower side of the sill opening portion 6, the partition plate 31 can also be used as the inner floor material of the tower column 2. In the above embodiment, the through hole 23 is provided in the column housing 21, and the connection between the ring spacer 34 and the flange portion 51a is utilized inside and outside the column housing 21. The addition of the contact plate 60 is performed. However, for example, in the modification of the seventh embodiment and the eighth embodiment, the through hole 23 is not provided, and the annular spacer 34 and the flange portion 51a are provided. The structure in which only the joining plates on the lower side are joined is used. In the column support structure having such a base joint portion 30A, the joint strength of the flange portion 51a is slightly deteriorated, but it has a man-hour and material cost required to reduce the construction of the portion of the -18-201124618. Therefore, it is only necessary to appropriately select various factors such as the height of the column 2 and the load conditions of the nacelle 3, etc. [Second Embodiment] Next, the above description will be described with reference to FIGS. 9 and 10 The second embodiment of the column support structure in which the column 2 is erected on the foundation B. It is to be noted that the same reference numerals are given to the same parts as those in the above embodiment, and the detailed description thereof will be omitted. In the base joint portion 30B of this embodiment, a cylindrical inner tube 32A that is combined with the column housing 21 with the upper end portion on the large diameter side is used instead of the cylindrical inner tube of the above embodiment. 32. That is, the inner cylinder 32A of the present embodiment has a structure in which the upper end portion of the large diameter is directly welded to the inner wall of the column housing 21, and the lower end portion of the small diameter is welded to the bottom plate 33. Therefore, the column housing is The stress transmission system that is transmitted to the inner cylinder 32A is different from the shape of the cylinder that is transmitted through the partition plate 31, and is directly transmitted, so that it tends to be smooth, and therefore, the stress transmission from the column 2 to the base B tends to be Yu Pingshun. According to the embodiment of the present invention described above, on the lower end side of the column 2, a concentric column housing 21 and a cylindrical inner tube 32 (or a truncated cone inner tube 32A) are provided. The base joints 30, 30A, 30B of the double tube structure. In the double pipe structure portion, by extending the inner cylinders 32, 32A to the inside of the base B of -19 - 201124618, the inner cylinders 32, 32A will be extended downward from the column housing 21. Then, when the column 2 is erected on the foundation B, the extension of the inner cylinders 32 and 32A and the column-side coupling member (the column-side bracket) provided in the range below the outer diameter of the column housing 21 3 5. The ring-shaped partition plate 3 4 and the bottom plate 3 3 ) are to be inserted into the column-column joint space portion 50 of the space of the unfilled concrete previously provided in the base B. Such a column-column joint space portion 50 is a space provided in the base B of the reinforced concrete, and is provided in the vicinity of the center portion in order to insert the lower end portion of the tower column 2, that is, the foundation B of this case is Reinforcing bars are placed around the column-combining space portion 50, and are filled with a state in which the concrete between the reinforcing bars has been hardened. Further, in the column-joining space portion 50, a base-side bracket (base side connecting member) 51 that is integrally held in the concrete with the base B is provided. The base side bracket 51 is, for example, a steel plate member having a substantially I-shaped cross section including flange portions 51a and 51b at both upper and lower end portions. After the extension of the inner cylinders 32 and 32A and the column-side coupling members (the column-side bracket 35, the ring-shaped partition plate 34, and the bottom plate 33) are inserted into the column-joining space portion 50, the additional plate 60 is used. The bolt and nut 70 connects the base side bracket 5 1 and the column side connecting member. Then, the concrete is filled into the column-column joint portion 50 of the space of the unfilled concrete, and after the concrete is hardened, the work of erecting the column 2 for the foundation B can be completed. Therefore, there is no longer such a member of the base plate 22 that is larger than the outer diameter of the column housing 21, and the outer diameter of the column housing 21 can be enlarged to a limit of -20-201124618 to the limit condition. Up to the size, can improve the efficiency of the area. Also, the outer diameter of the column 2 can be regarded as the diameter of the outer diameter of the column housing 21. According to the single column column and the wind power generation device of the present invention, the outer diameter of the column housing 21 can be regarded as the maximum outer diameter of the column, and the outer diameter of the column housing 21 can be enlarged to the maximum. The efficiency can be improved by the limit, and it can be achieved that the column support structure of the largest outer diameter is created within the range of reducing the weight. That is, in the wind turbine generator 1 having the single column 2, by adopting the tower structure of the above-described embodiment, the outer dimensions of the column housing 21 can be regarded as the final result thereof, In the case of the tower 2 in which the size of the wind power generator 1 is increased and the load conditions are more stringent, it is easy to simultaneously transmit the restriction conditions such as the limit and the two types of the required strength, and the thickness of the column 2 can be changed. Thin, it becomes a wind power generator with a weight-reducing structure. Further, the brackets 35, 51, and the additional plates 60 can be used with low-priced steel sheets, and it is no longer necessary to use expensive base flanges 22 and ground. Since the anchor screw and the nut 11 are provided, the cost of the wind power generator 1 can be reduced. Furthermore, since it is not necessary to use the ground anchor bolt 10, it is no longer necessary to perform maintenance work such as locking nuts. Further, when the outer diameter of the column casing 21 is increased, the outer diameter of the flange for coupling between the towers is also increased, so that the size and number of the bolts for the joint can be reduced. That is, the tower is the largest externally, because the large-diameter outer diameter of the standard column column column can be increased due to the amount of the area that can be broken, and the roller bolt 10 of the tower column is connected to the flange portion of the column section - 21 - 201124618 In addition, the present invention is not limited to the above-described embodiment, and can be applied to, for example, an upwind type and a downwind type wind power generator, and can be appropriately changed without departing from the scope of the invention.
