Description

本発明は、塔モジュール及びこれを用いて形成する塔に係り、特にプロペラ型風車発電機を支持する塔に対して好適な塔モジュール及びこれを用いて形成する塔に関する。   The present invention relates to a tower module and a tower formed using the tower module, and more particularly to a tower module suitable for a tower supporting a propeller type wind turbine generator and a tower formed using the tower module.

風力発電はクリーンエネルギーとして注目され、風力発電による発電量の増大を図るために発電コスト低減の種々の試みがなされている。発電コスト低減の一の方向として、発電効率の高いプロペラ型風車を用いた一層効率の高い風力発電装置の開発が進められ、プロペラ型風車発電機の大型化及びそれを支持する塔の高さの高度化が進んでいる。   Wind power generation has attracted attention as clean energy, and various attempts have been made to reduce power generation costs in order to increase the amount of power generated by wind power generation. As one direction to reduce power generation costs, the development of higher-efficiency wind power generators using propeller-type windmills with higher power generation efficiency has been promoted, and the size of propeller-type windmill generators and the height of the towers that support them have increased. Advancement is progressing.

例えば、プロペラの長さ及び塔の高さが50mを超える風力発電装置が製作されており、その塔には通常は直立した円筒状のモノポール型のものが用いられている。このような風力発電装置においては、プロペラ型風車発電機の重量が50トン前後にもなるから塔の強度を確保することが重要になる。塔の強度確保において、曲げモーメントは塔の下方ほど大きくなるために、塔の下方部分ほど大きい曲げ剛性を確保することが必要になる。このため上記のような例では、塔の下端部の直径は3m前後になり、塔の重量は100トンを超えるようなものになっている。   For example, a wind power generator having a propeller length and a tower height of more than 50 m is manufactured, and an upright cylindrical monopole type is usually used for the tower. In such a wind turbine generator, since the weight of the propeller type wind turbine generator is about 50 tons, it is important to ensure the strength of the tower. In securing the strength of the tower, since the bending moment increases toward the bottom of the tower, it is necessary to ensure a large bending rigidity at the bottom of the tower. Therefore, in the above example, the diameter of the lower end of the tower is about 3 m, and the weight of the tower exceeds 100 tons.

このような大型の風力発電装置においては、風力発電装置の設置現場へのその構成部材の輸送や塔の基礎を含めた風力発電装置の組立て上の困難さ、建設コストの上昇等が問題になっている。また、塔の強度に与える風圧の影響が大きいことが問題になっている。このような問題に対し、例えば特許文献1に脚構造体の塔が提案されている。すなわち、風車を旋回可能に支持する風車支持部を備える塔であって、岩盤基礎に各脚の下端部が固定され、各脚の上端部が上方に集束して、全体として上向きに先細形状をなす複数の三角脚鉄塔構造又は四角脚鉄塔構造からなる塔が提案されている。   In such a large-scale wind turbine generator, problems such as the difficulty in assembling the wind turbine generator including the transportation of its components to the installation site of the wind turbine generator and the foundation of the tower, and the increase in construction cost become problems. ing. Another problem is that the influence of wind pressure on the tower strength is large. For such a problem, for example, Patent Document 1 proposes a tower of leg structures. That is, it is a tower provided with a windmill support part that supports the windmill so as to be able to turn, and the lower end part of each leg is fixed to the bedrock foundation, the upper end part of each leg converges upwardly, and the tapered shape is formed upward as a whole. A tower composed of a plurality of triangular legged tower structures or square legged tower structures has been proposed.

特開2002-61564号公報JP 2002-61564 A

しかしながら特許文献1の提案に係る塔は、3又は4本の立設する主柱が上方で集束した脚構造体であるから、上記のような大型のプロペラ型風車発電機を支持するには強度上の問題がある。また、このような脚構造体は、一般に負荷の方向によって曲げ剛性が異なる。このため、プロペラ型風車発電機がどの方向を向いても塔の強度が確保できるように、低い曲げ剛性の方向の強度を基準に設計されるので、塔のサイズ、重量が大きくなりやすいという問題がある。さらに、風力発電装置を設置する際の塔構成品の輸送及び建設上の問題も十分には解決されていない。   However, since the tower according to the proposal of Patent Document 1 is a leg structure in which three or four main pillars are vertically converged, it is strong enough to support a large propeller-type wind turbine generator as described above. There is a problem above. In addition, such a leg structure generally has different bending rigidity depending on the direction of the load. For this reason, the design is based on the strength in the direction of low bending rigidity so that the strength of the tower can be ensured regardless of the direction of the propeller type wind turbine generator, so the size and weight of the tower tends to increase. There is. Furthermore, the problem of transportation and construction of tower components when installing a wind turbine generator has not been sufficiently solved.

このような脚構造体は従来より高圧電線用鉄塔や通信塔にも採用されているが、いずれもその基本構造は、3又は4本の立設する主柱と、これらを連結する補助部材、すなわちそれらの主柱の適当な高さ位置に間隔を置いて配設した連結部材からなる構造となっており、主柱の強度が重要な要素になっている。このため、塔は主柱の最大負荷を受ける部分を基準に設計されるから主柱のサイズが大きくなりひいては塔の重量が大きくなりやすいという問題もある。   Such a leg structure has been conventionally used for high-voltage electric power towers and communication towers, but the basic structure of each is three or four main pillars to be erected, and auxiliary members for connecting them, That is, it has a structure composed of connecting members disposed at appropriate height positions of the main pillars at an interval, and the strength of the main pillars is an important factor. For this reason, since the tower is designed on the basis of the portion of the main column that receives the maximum load, there is a problem that the size of the main pillar increases and the weight of the tower easily increases.

本発明はこのような従来の問題点に鑑み、塔構成部材の輸送及び塔建設時の問題点を解決するとともに、曲げ剛性が高く軽量な塔モジュール及びこれを用いて形成する塔を提供することを目的とする。   In view of such a conventional problem, the present invention provides a tower module having a high bending rigidity and a light weight, and a tower formed using the tower module, while solving the problems of transportation of tower components and tower construction. With the goal.

本発明者は、連結部材と、該連結部材に対し、同一の長さ及び同一の曲げ剛性を有し、円周上120°の角度を離間するように配置固定された3本の棒をセットとする1以上の棒群と、からなる柱状体の中心軸回りの曲げ剛性は、どの方向についても等しく、このような柱状体を塔モジュールとして塔を形成すれば軽量でプロペラ型風車発電装置に好適な塔を形成することができるという知見に基づき本発明を完成した。   The inventor sets a connecting member and three rods having the same length and the same bending rigidity with respect to the connecting member and arranged and fixed so as to be spaced apart at an angle of 120 ° on the circumference. The bending rigidity around the central axis of the columnar body consisting of one or more rod groups is equal in any direction, and if such a columnar body is used as a tower module to form a tower, the propeller type wind turbine generator can be reduced in weight. The present invention has been completed based on the finding that a suitable tower can be formed.

本発明に係る塔は、連結部材と、該連結部材に対し、同一の長さ及び同一の曲げ剛性を有し、円周上に120°の角度を離間するように配置固定された3本の棒をセットとする1以上の棒群と、からなる塔モジュールを、複数個積み上げ連結してなる。   The tower according to the present invention includes a connecting member, and three connecting members that have the same length and the same bending rigidity, and are arranged and fixed so as to be spaced apart at an angle of 120 ° on the circumference. A plurality of tower modules composed of a group of one or more bars each having a set of bars are stacked and connected.

上記発明において、塔は、その最下段の塔モジュールが最上段の塔モジュールよりも大きい曲げ剛性を有するように連結してなるのがよい。   In the above invention, the towers are preferably connected so that the lowermost tower module has higher bending rigidity than the uppermost tower module.

本発明に係る塔を構成する塔モジュールは、連結部材と、該連結部材に対し、同一の長さ及び同一の曲げ剛性を有し、円周上に120°の角度を離間するように配置固定された3本の棒をセットとする1以上の棒群と、からなる。上記塔モジュールにおいて下及び上連結部材は環状体であるのが好ましい。   The tower module constituting the tower according to the present invention has a connecting member, and the connecting member has the same length and the same bending rigidity, and is arranged and fixed so as to be spaced apart at an angle of 120 ° on the circumference. And a group of one or more rods each having a set of three rods. In the tower module, the lower and upper connecting members are preferably annular bodies.

本発明に係る塔は、上記の塔モジュールを複数個積み重ね連結してなるものであるが、
塔を設置する現場で、塔モジュールを構成する部材を個々に組み付けて塔を形成することができる。すなわち、(1)基礎上に、同一の長さ及び同一の曲げ剛性を有する3本の棒をセットとする1以上の棒群を、同一の棒群に属する3本の棒が円周上に120°の角度を離間するように配置して立設固定し、さらに、該棒群上に連結部材を固定して第一の塔モジュールを構築する段階、(2)前記第一の塔モジュールの上に、同一の長さ及び同一の曲げ剛性を有する3本の棒をセットとする1以上の棒群を、同一の棒群に属する3本の棒が円周上に120°の角度を離間するように配置して立設固定し、さらに、該棒群上に連結部材を固定して第二の塔モジュールを構築する段階、からなる塔の形成方法により、または、さらに前記(2)の段階を1以上繰り返す段階を含んでなる塔の形成方法により、塔を形成することができる。
The tower according to the present invention is formed by stacking and connecting a plurality of the above tower modules,
At the site where the tower is installed, the tower can be formed by individually assembling the members constituting the tower module. That is, (1) on a foundation, one or more rod groups each including a set of three rods having the same length and the same bending rigidity, and three rods belonging to the same rod group on the circumference A step of arranging the first tower module so as to be spaced apart at an angle of 120 °, and further fixing a connecting member on the rod group, and (2) the first tower module Above, one or more rod groups consisting of three rods having the same length and the same bending rigidity, and three rods belonging to the same rod group are spaced 120 ° apart on the circumference The method of forming a tower comprising the steps of: arranging and fixing in a standing manner; and fixing the connecting member on the rod group to construct a second tower module; or further according to (2) A tower can be formed by a method for forming a tower comprising a step of repeating one or more steps.

本発明に係る塔モジュールは軽量で曲げ剛性が大きく、かつその中心軸回りのどの方向の曲げ剛性も等しい。係る塔モジュールを用いて形成された塔は、軽量で塔の中心軸回りに関してどの方向の曲げ剛性も等しく、プロペラ型や多翼型の水平軸型風車、ダリウス型やサボニウス型の垂直軸型風車等の風車発電装置用の塔や通信塔等の鉄塔、特に塔頂部で重量物を支持しかつ塔の中心軸回りのどの方向にも高い曲げ剛性が要求されるプロペラ型風車発電装置用の塔に好適に用いることができる。また、塔構成部材をプロペラ型風車発電装置等の設置現場まで輸送するのに適宜で経済的な手段を選択することができ、輸送された塔構成部材を用いて現場で容易に塔を形成することができる。   The tower module according to the present invention is light and has high bending rigidity, and the bending rigidity in any direction around the central axis is equal. A tower formed using such a tower module is light and has the same bending rigidity in any direction around the center axis of the tower, and is a propeller type or multiblade horizontal axis type windmill, Darius type or Savonius type vertical axis type windmill. Towers for wind turbine generators such as towers and towers for communication towers, especially towers for propeller type wind turbine generators that support heavy objects at the top of the tower and require high bending rigidity in any direction around the central axis of the tower Can be suitably used. In addition, an appropriate and economical means can be selected for transporting the tower component to the installation site of the propeller type wind turbine generator, etc., and the tower can be easily formed on the site using the transported tower component. be able to.

以下に、本発明に係る塔の実施の形態について図を基に説明する。本発明に係る塔は、例えば図1,2に示すように図3及び4に示す塔モジュールが連結されて形成される。すなわち、図1に示す塔は、図3に示す塔モジュール10が2個ねじ結合20により連結されて形成される場合の例である。図2に示す塔は、図4に示す塔モジュール11の上に図3に示す塔モジュール10が積み重ねられねじ結合20により連結されて形成される場合の例である。このように本発明に係る塔は、塔の性能仕様(所要の高さ、強度)を満たすように所要の塔モジュールを組み合わせ連結して形成されるものである。   Hereinafter, embodiments of a tower according to the present invention will be described with reference to the drawings. The tower according to the present invention is formed, for example, by connecting tower modules shown in FIGS. 3 and 4 as shown in FIGS. That is, the tower shown in FIG. 1 is an example in which the tower module 10 shown in FIG. The tower shown in FIG. 2 is an example where the tower module 10 shown in FIG. 3 is stacked on the tower module 11 shown in FIG. Thus, the tower according to the present invention is formed by combining and connecting required tower modules so as to satisfy the performance specifications (required height and strength) of the tower.

本発明に係る塔モジュールは、連結部材と、該連結部材に対し3本の棒ごとにセットになって一体に連結された1以上の棒群とから構成される基本構造をなしている。例えば、図3に示す塔モジュール10は、3本の棒101からなる棒群100と、棒群100の下端を連結する下連結部材150と、棒群100の上端を連結する上連結部材160とから構成される。図4に示す塔モジュール11は、3本の棒101からなる棒群100及び3本の棒111からなる棒群110と、棒群100及び110の下端を連結する下連結部材151と、棒群100及び110の上端を連結する上連結部材161とから構成される。塔モジュールの曲げ剛性は、多数の棒群を有するものほど大きい。このため、一般には塔の下部を構成する塔モジュールほど、多くの棒群を有するものが用いられる。   The tower module according to the present invention has a basic structure composed of a connecting member and one or more rod groups that are integrally connected to the connecting member as a set of three bars. For example, the tower module 10 shown in FIG. 3 includes a bar group 100 including three bars 101, a lower connecting member 150 that connects the lower ends of the bar group 100, and an upper connecting member 160 that connects the upper ends of the bar group 100. Consists of The tower module 11 shown in FIG. 4 includes a rod group 100 composed of three rods 101 and a rod group 110 composed of three rods 111, a lower connecting member 151 that connects the lower ends of the rod groups 100 and 110, and a rod group And an upper connecting member 161 that connects the upper ends of 100 and 110. The bending rigidity of the tower module is larger as it has a larger number of rod groups. For this reason, generally, the tower module which comprises the lower part of a tower uses what has many rod groups.

一の塔モジュールを構成する棒群において、すべての棒の長さは同一である。また、同じ棒群に属する3本の棒の曲げ剛性(棒の横断面の断面二次極モーメントIz、ヤング率Eとすると、E×Iz)も同一である。   In the group of bars constituting one tower module, all the bars have the same length. In addition, the bending rigidity of the three rods belonging to the same group of rods (the cross-sectional secondary pole moment Iz of the rod cross section, E × Iz when Young's modulus is E) is the same.

また、同じ棒群に属する3本の棒は、円周上に120°の角度を離間して配置される。例えば、図3の例では、棒群100を構成する3本の棒101は、下連結部材150の円周C1上及び上連結部材160の円周D1上120°の角度を離間し、すなわちθ=120°の中心角をなし円周上等間隔に配置されている。図4の例では、棒群100を構成する1の組の3本の棒101は、図3に示すものと同様に下連結部材151の円周C1上及び上連結部材161の円周D1上に120°の角度を離間して配置され、棒群110を構成する2の組の3本の棒111は、棒101の配置位置から角度αずれた下連結部材151の円周C1上及び上連結部材161の円周D1上に互いに120°離間して配置されている。 Further, the three bars belonging to the same bar group are arranged on the circumference at an angle of 120 °. For example, in the example of FIG. 3, the three bars 101 constituting the bar group 100 are separated by an angle of 120 ° on the circumference C 1 of the lower connecting member 150 and the circumference D 1 of the upper connecting member 160, That is, it has a central angle of θ = 120 ° and is arranged at equal intervals on the circumference. In the example of FIG. 4, one set of three rods 101 constituting the rod group 100 is arranged on the circumference C 1 of the lower connecting member 151 and the circumference D of the upper connecting member 161 in the same manner as shown in FIG. The two pairs of three bars 111 that are arranged at an angle of 120 ° on 1 and constitute the group of bars 110 are the circumference C 1 of the lower connecting member 151 that is shifted from the position of the bars 101 by an angle α. The upper and upper connecting members 161 are arranged on the circumference D 1 so as to be separated from each other by 120 °.

このように構成された塔モジュールの曲げ剛性は、上又は下連結部材面に対して直角方向、すなわち塔モジュールの中心軸回りにどの方向についても等しい。なお、図4の例で、2の組の3本の棒111が下連結部材15の円周C2上に120°の角度を離間して配置されていてもよい。この場合も、同じ組に属する3本の棒が円周上に120°の角度を離間して配置されているので、塔モジュールの曲げ剛性はどの方向についても等しい。 The bending rigidity of the tower module configured in this way is equal in any direction perpendicular to the upper or lower connecting member surface, that is, around the central axis of the tower module. In the example of FIG. 4, two sets of three bars 111 may be disposed on the circumference C 2 of the lower connecting member 15 at an angle of 120 °. Also in this case, since the three bars belonging to the same group are arranged on the circumference at an angle of 120 °, the bending rigidity of the tower module is the same in any direction.

棒群100、110が配置される上記円周C1とD1に関し相互の径の大小は問わない。しかしながら、塔の上部ほど塔に負荷される曲げモーメントは小さく、上部の塔モジュールの曲げ剛性は下部のものより小さくすることができるので、円周D1を円周C1より小さくするのがよい。これにより、上連結部材161を外径の小さいものにすることができ塔全体の重量軽減を図ることができる。 The diameters of the circumferences C 1 and D 1 where the rod groups 100 and 110 are arranged are not limited. However, since the bending moment applied to the tower is smaller at the upper part of the tower, and the bending rigidity of the upper tower module can be made smaller than that at the lower part, the circumference D 1 should be smaller than the circumference C 1. . As a result, the upper connecting member 161 can have a small outer diameter, and the weight of the entire tower can be reduced.

なお、棒群を構成する棒は、中実又は中空のいずれのものも使用することができ、断面形状は円形又は角形のいずれのものをも使用することができる。また、棒の上部ほど断面積が小さくなるような、例えば、円錐柱形状の棒も使用することができる。しかしながら、経済性を考慮すると、広く市販されている、丸棒、丸又は角パイプ、H形鋼、L形鋼を使用するのがよい。   Note that the rods constituting the rod group can be either solid or hollow, and the cross-sectional shape can be either circular or square. In addition, for example, a conical column-shaped rod having a smaller cross-sectional area toward the top of the rod can be used. However, considering economy, it is preferable to use round bars, round or square pipes, H-section steel, and L-section steel that are widely available on the market.

棒群を連結する下連結部材及び上連結部材は、棒群と一体に結合されて塔モジュールを構成するものであるが、塔モジュールの全体重量やねじり強度に与える影響が大きい。このためねじり強度が高くしかも重量が軽いものが求められる。例えば、図5に示すような環状体の下連結部材又は上連結部材が好ましい。図5の(a)は丸パイプを円環状に曲げ加工した構造のもの、(b)は中心部をくりぬいた六角形状の板からなる構造のもの、(c)はL形鋼を六角形状に連結した構造のものを示す。なお、棒群と上又は下連結部材との結合方法は、溶接、ねじ等の結合方法を使用することができ、適当な結合強度を有するいずれの方法も使用することができる。   The lower connecting member and the upper connecting member that connect the rod group are combined integrally with the rod group to constitute the tower module, but have a great influence on the overall weight and torsional strength of the tower module. For this reason, a material with high torsional strength and light weight is required. For example, a lower connecting member or an upper connecting member as shown in FIG. 5 is preferable. Fig. 5 (a) shows a structure in which a round pipe is bent into an annular shape, (b) shows a structure consisting of a hexagonal plate with a hollowed center, and (c) shows an L-shaped steel in a hexagonal shape. The connected structure is shown. In addition, the joining method of a rod group and an upper or lower connection member can use joining methods, such as welding and a screw | thread, and can use any method which has suitable joint strength.

このような塔モジュールを連結して形成した塔は、塔のどの方向の曲げ剛性も等しくなる。従って、プロペラ型風車発電装置において、プロペラ型風車がどの方向を向いていても塔は一定の曲げ強度を有し、塔の軽量化を図ることができる。また、塔の受ける風圧を小さくすることができる。このような塔を構成する塔モジュールは、上記に示す実施例に限らない。例えば、図6に示す構成の塔モジュールでもよい。図6(a)に示す塔モジュール12は、図1の塔モジュールにおいて下連結部材を欠く構造をしており、3本の棒101からなる棒群100とその上端を連結する上連結部材160により構成されている。図6(b)に示す塔モジュール13は、図1の塔モジュールにおいて上連結部材を欠く構造をしており、3本の棒101からなる棒群100とその下端を連結する下連結部材150により構成されている。   A tower formed by connecting such tower modules has the same bending rigidity in any direction of the tower. Therefore, in the propeller type windmill power generator, the tower has a certain bending strength regardless of the direction of the propeller type windmill, and the weight of the tower can be reduced. Moreover, the wind pressure which a tower receives can be made small. The tower module constituting such a tower is not limited to the embodiment described above. For example, a tower module configured as shown in FIG. 6 may be used. The tower module 12 shown in FIG. 6 (a) has a structure lacking the lower connecting member in the tower module of FIG. 1, and includes a bar group 100 composed of three bars 101 and an upper connecting member 160 that connects the upper ends thereof. It is configured. The tower module 13 shown in FIG. 6 (b) has a structure lacking the upper connecting member in the tower module of FIG. 1, and includes a group of three rods 101 and a lower connecting member 150 that connects the lower ends thereof. It is configured.

図6(a)に示す塔モジュール12を3段に積み重ね連結して形成した塔の実施例を図7に示す。さらに、図7に示す塔にベース部材170を追加した構造の塔の実施例を図8に示す。このようなベース部材170は、塔を設置する基礎の構造によって必要になる場合がある。なお、塔モジュールの曲げ剛性はその軸の周りのいずれの方向にも等しいから、図7に示すように連結される塔モジュールのそれぞれの棒の配置に関係なく、塔モジュールを連結することができる。すなわち、塔を形成する3つの塔モジュール12の棒群100を構成する棒が、塔の上下方向一直線上にあるように塔モジュール12を連結しなくてもよい。棒群を構成する棒は、塔モジュールの一部分であって、塔を構成する主柱としての機能を有してはいない。   FIG. 7 shows an embodiment of a tower formed by stacking and connecting the tower modules 12 shown in FIG. Further, FIG. 8 shows an embodiment of a tower in which a base member 170 is added to the tower shown in FIG. Such a base member 170 may be necessary depending on the structure of the foundation on which the tower is installed. Since the bending rigidity of the tower module is equal in any direction around the axis, the tower modules can be connected regardless of the arrangement of the respective rods of the tower modules to be connected as shown in FIG. . That is, it is not necessary to connect the tower modules 12 so that the rods constituting the rod group 100 of the three tower modules 12 forming the tower are on the vertical line of the tower. The rods constituting the group of rods are part of the tower module and do not have a function as a main pillar constituting the tower.

図9に、図6(b)に示す塔モジュール13を3段に連結し、さらに、塔の頂部にヘッド部材175を追加してプロペラ型風車発電機の設置部を設けた塔の例を示す。このように塔の頂部あるいは塔の下端部は、プロペラ型風車発電機の設置部分となりあるいは塔の基礎と連結される部分となり、特異な部位であるから適宜所要の部材が追加され、また、追加工がされる場合が少なくない。   FIG. 9 shows an example of a tower in which the tower module 13 shown in FIG. 6 (b) is connected in three stages, and a head member 175 is added to the top of the tower to provide a propeller type wind turbine generator installation section. . In this way, the top of the tower or the lower end of the tower becomes an installation part of the propeller type wind turbine generator or a part connected to the foundation of the tower, and since it is a unique part, necessary members are added as appropriate. There are many cases where work is done.

塔モジュールの連結方法は、塔の性能仕様、経済性等を考慮してねじ結合、溶接等適切な方法が選択される。塔モジュールをネジ結合により連結する場合は、塔モジュールの上連結部材とその上に積み重ねられる塔モジュールの下連結部材とをねじ及びナットにより直接結合して塔モジュールを連結する方法の他、例えば図10に示すように上連結部材と下連結部材の間にスペーサーを介して塔モジュールを連結する方法も用いられる。図10(a)は、2つの塔モジュール10を、上連結部材160と下連結部材150の間に円板状のスペーサー21を介してボルト25及びナット26で連結する例を示す。図10(b)は、2つの塔モジュール10を、上連結部材160と下連結部材150の間に円筒状のスペーサー23を介してボルト25及びナット26で連結する例を示す。   As a method for connecting the tower modules, an appropriate method such as screw connection or welding is selected in consideration of the performance specifications and economics of the tower. When the tower modules are connected by screw connection, the tower module upper connection member and the tower module lower connection member stacked on the tower module are directly connected by screws and nuts to connect the tower module. As shown in FIG. 10, a method of connecting the tower module via a spacer between the upper connecting member and the lower connecting member is also used. FIG. 10A shows an example in which two tower modules 10 are connected between the upper connecting member 160 and the lower connecting member 150 with a bolt 25 and a nut 26 via a disc-like spacer 21. FIG. 10B shows an example in which two tower modules 10 are connected between the upper connecting member 160 and the lower connecting member 150 with a bolt 25 and a nut 26 via a cylindrical spacer 23.

以上、塔モジュールを連結して塔を形成する例について説明した。これらの塔は、工場で製造された塔モジュールを塔の設置現場に輸送し、現場で塔モジュールを積み重ね連結して形成されるのが一般的である。しかしながら、塔の設置現場が交通不便な所であるような場合等には、塔モジュールを構成する部材を分解した状態で塔設置現場まで輸送し、一つ一つ現場で組み付けて塔を形成するのが好ましい場合がある。そのような場合は、例えば、塔の設置現場に輸送された棒、連結部材を用いて図11に示す方法により容易に塔を形成することができる。   In the above, the example which connects a tower module and forms a tower was demonstrated. These towers are generally formed by transporting tower modules manufactured in a factory to a tower installation site and stacking and connecting the tower modules on the spot. However, when the installation site of the tower is inconvenient, etc., the members constituting the tower module are transported to the tower installation site in a disassembled state, and assembled at the site one by one to form the tower May be preferred. In such a case, for example, the tower can be easily formed by the method shown in FIG. 11 using the rod and the connecting member transported to the installation site of the tower.

図11に示す方法は、先ず、3本の棒115からなる棒群120を基礎50に固定し、その上端に連結部材165を組み付けることから行う。次に、その連結部材165の上に3本の棒116からなる棒群130を組み付け、その上端に連結部材166を取り付ける。さらに、連結部材166の上に3本の棒117からなる棒群140を組み付け、その上端に連結部材167を取り付けて塔を形成する。なお、上記の各段階を繰り返すことによってさらに高い塔を形成することができる。また、棒群と連結部材の結合は、溶接あるいはねじ結合等所要の結合方法を使用することができる。   The method shown in FIG. 11 is performed by first fixing a group of rods 120 including three rods 115 to the foundation 50 and assembling a connecting member 165 at the upper end thereof. Next, the rod group 130 including the three rods 116 is assembled on the connecting member 165, and the connecting member 166 is attached to the upper end thereof. Further, a bar group 140 including three bars 117 is assembled on the connecting member 166, and a connecting member 167 is attached to the upper end thereof to form a tower. It should be noted that a higher tower can be formed by repeating the above steps. Further, for the connection between the rod group and the connecting member, a required connecting method such as welding or screw connection can be used.
