図１（Ａ）は本発明の一実施形態に係る構築装置１の正面図、図１（Ｂ)は構築装置１の平面図である。構築装置１は、構築対象の塔状構造物（図１（Ａ）及び（Ｂ）において不図示）のコンクリート基礎２００上に仮設され、塔状構造物の完成後に撤去される。構築装置１は、構造体１０と、吊り架台２０と、昇降機構３０、３０と、案内機構４０と、支持機構５０と、導入装置６０と、吊り装置７０と、を備える。   FIG. 1A is a front view of the construction apparatus 1 according to an embodiment of the present invention, and FIG. 1B is a plan view of the construction apparatus 1. The construction apparatus 1 is temporarily installed on the concrete foundation 200 of the tower-like structure to be constructed (not shown in FIGS. 1A and 1B), and is removed after the tower-like structure is completed. The construction apparatus 1 includes a structure 10, a suspension base 20, elevating mechanisms 30 and 30, a guide mechanism 40, a support mechanism 50, an introduction device 60, and a suspension device 70.

構造体１０は構築装置１の本体をなし、複数の柱用鋼材１１及び梁用鋼材１２を組み合わせて構成された、外形が角筒状で鉄骨造の枠体である。構造体１０には、補強用のブレースや作業者の足場等を更に備えるが図示を省略している。構造体１０は、塔状構造物（不図示）を構成する柱部材２が導入される導入空間Ｓ１と、導入空間Ｓ１の上方の上部空間Ｓ２とを形成している。   The structure 10 is a main body of the construction apparatus 1 and is a steel frame structure having an outer shape of a rectangular tube formed by combining a plurality of column steel members 11 and beam steel members 12. The structure 10 further includes a brace for reinforcement, a scaffold for workers, etc., but is not shown. The structure 10 forms an introduction space S1 into which a column member 2 constituting a tower-like structure (not shown) is introduced, and an upper space S2 above the introduction space S1.

吊り架台２０には、導入空間Ｓ１に導入された柱部材２が搭載される。本実施形態の場合、柱部材２は鉄筋コンクリート製の円筒部２ａの両端部に、フランジ部２ｂをそれぞれ形成したものである。フランジ部２ｂは例えばフランジ部２ｂを構成する金物を円筒部２ａの両端部に固定して形成することができる。このフランジ部は柱部材２間を連結するため、ボルトによる締結部として用いられる。   The column member 2 introduced into the introduction space S1 is mounted on the suspension base 20. In the case of this embodiment, the pillar member 2 is formed by forming flange portions 2b at both ends of a cylindrical portion 2a made of reinforced concrete. The flange portion 2b can be formed, for example, by fixing hardware constituting the flange portion 2b to both ends of the cylindrical portion 2a. Since this flange part connects between the column members 2, it is used as a fastening part by a volt | bolt.

図１（Ｃ）は吊り架台２０の平面図であり、吊り架台２０は鋼材２１、２２を組み合わせて構成された方形の枠体を備える。各鋼材２１の中央部には、吊り金具２４が固定されている。   FIG. 1C is a plan view of the suspension base 20, and the suspension base 20 includes a square frame configured by combining steel materials 21 and 22. A suspension fitting 24 is fixed to the central portion of each steel material 21.

鋼材２２、２２間には一対の可動の載置部２３、２３が架設されている。各載置部２３は、スライド部２３ａ、２３ａと、スライド部２３ａ、２３ａ間に架設された鋼材２３ｂと、係合板２３ｃと、を備え、矢印方向にスライド可能となっている。   A pair of movable mounting parts 23 and 23 are installed between the steel materials 22 and 22. Each mounting portion 23 includes slide portions 23a and 23a, a steel material 23b provided between the slide portions 23a and 23a, and an engagement plate 23c, and is slidable in the direction of the arrow.

スライド部２３ａは、例えば、鋼材２２が挿通する筒体をなし、鋼材２２に沿ってスライド可能になっている。係合板２３ｃは鋼材２３ｂ上に固定されており、柱部材２のフランジ部２ｂと重なる面積が多くなるように内側が弧状に切り欠かれている。   The slide part 23 a is, for example, a cylinder through which the steel material 22 is inserted, and is slidable along the steel material 22. The engagement plate 23c is fixed on the steel material 23b, and the inner side is cut out in an arc shape so that the area overlapping the flange portion 2b of the column member 2 is increased.

載置部２３を矢印方向にスライド可能とすることで載置部２３、２３の間隔を変更でき、異径の柱部材２に対応できる。また、後述するように塔状構造物を建て込む際にこのスライドを活用することができる。鋼材２２に対する載置部２３の位置の固定は、例えば、鋼材２２及びスライド部２３ａにそれぞれ、スライド方向に沿った複数の孔を形成しておき、ピンを選択的に挿入して係合する係合機構により行うことができる。   By making the mounting portion 23 slidable in the direction of the arrow, the interval between the mounting portions 23 and 23 can be changed, and the column member 2 having a different diameter can be handled. Moreover, this slide can be utilized when building a tower-like structure so that it may mention later. The mounting portion 23 is fixed to the steel material 22 by, for example, forming a plurality of holes along the sliding direction in the steel material 22 and the slide portion 23a, and selectively inserting and engaging pins. This can be done by a combination mechanism.

図１（Ａ）及び図１（Ｃ)を参照して、昇降機構３０は吊り架台２０を昇降する機構であり、本実施形態の場合、水平方向に離間して２基設けられて構造体１０の上部に支持されている。昇降機構３０はチェーンやワイヤ等の吊材３０ａを備え、吊材３０ａの先端は吊り金具２４に連結されている。本実施形態の場合、昇降機構３０として電動チェーンブロックを想定するが、ホイスト、VSL、ステップロッド、ネジロッドジャッキ等、他の昇降機構であってもよい。しかして、吊材３０の巻き上げ、巻き戻しにより吊り架台２０を昇降することができる。昇降機構３０は、塔状構造物或いはその構築途中段階における柱部材２の連結体をリフトアップするため、そのリフトアップが可能な容量のものを使用する。   Referring to FIGS. 1A and 1C, the lifting mechanism 30 is a mechanism for lifting and lowering the suspension base 20, and in the case of this embodiment, two structures are provided apart from each other in the horizontal direction. Supported at the top of the. The elevating mechanism 30 includes a suspension member 30 a such as a chain or a wire, and the tip of the suspension member 30 a is connected to the suspension fitting 24. In the case of the present embodiment, an electric chain block is assumed as the elevating mechanism 30, but other elevating mechanisms such as a hoist, a VSL, a step rod, and a screw rod jack may be used. Thus, the suspension base 20 can be moved up and down by winding and unwinding the suspension member 30. The lifting mechanism 30 uses a capacity that can lift up the tower-like structure or the connected body of the column members 2 in the middle of its construction.

次に、図１（Ａ）、図１（Ｂ)、図２（Ａ)及び図２（Ｂ)を参照して案内機構４０について説明する。図２（Ａ）は案内機構４０の説明図であり、その平面図である。図２（Ｂ）はレール部材４１の斜視図である。案内機構４０は、レール部材４１と、スライド部材４２と、を備え、上部空間Ｓ２において、リフトアップ中の柱部材２単体及びその連結体の上下移動を案内する。   Next, the guide mechanism 40 will be described with reference to FIGS. 1 (A), 1 (B), 2 (A), and 2 (B). FIG. 2A is an explanatory view of the guide mechanism 40 and is a plan view thereof. FIG. 2B is a perspective view of the rail member 41. The guide mechanism 40 includes a rail member 41 and a slide member 42, and guides the vertical movement of the column member 2 alone and its connecting body during lift-up in the upper space S2.

レール部材４１は本実施形態の場合Ｉ型鋼であり、支持部材１３等を介して構造体１０に固定されている。本実施形態の場合、レール部材４１は９０度間隔で４本設けられ、各レール部材４１は上部空間Ｓ２において上下方向に延設されている。レール部材４１の一方のフランジ部の表面４１ａはスライド部材４２が摺接する、垂直方向の案内面を構成し、他方のフランジ部側は構造体１０との干渉を回避する切り欠き４１ｂが形成されている。４つのレール部材４１は、そのうちの２つのレール部材４１の表面４１ａが互いに対向するように配置されている。   In this embodiment, the rail member 41 is I-shaped steel, and is fixed to the structure 10 via the support member 13 or the like. In the case of this embodiment, four rail members 41 are provided at intervals of 90 degrees, and each rail member 41 extends in the vertical direction in the upper space S2. A surface 41a of one flange portion of the rail member 41 constitutes a vertical guide surface with which the slide member 42 comes into sliding contact, and a notch 41b is formed on the other flange portion side to avoid interference with the structure 10. Yes. The four rail members 41 are arranged so that the surfaces 41a of the two rail members 41 face each other.

スライド部材４２は柱部材２の周面に装着され、塔状構造物の構築途中で撤去される。スライド部材４２は、柱部材２の長手方向の複数の部位において、レール部材４１の配置に合わせて９０度間隔で柱部材２の周面に固定されており、柱部材２の径方向に突出している。スライド部材４２の先端部には、レール部材４１の表面４１ａに摺接して滑動する当接部材４２ａが固定されている。当接部材４２ａは、例えば合成繊維等からなる滑り部材であることが好ましい。当接部材４２ａの両側部には、突起部４２ｂ、４２ｂが形成されている。突起部４２ｂ、４２ｂはレール部材４１のフランジ部を挟むように配置され、フランジ部側面と当接することで、リフトアップ中の柱部材２の回り止めとなっている。   The slide member 42 is mounted on the peripheral surface of the column member 2 and is removed during the construction of the tower-like structure. The slide member 42 is fixed to the peripheral surface of the column member 2 at intervals of 90 degrees in accordance with the arrangement of the rail member 41 at a plurality of portions in the longitudinal direction of the column member 2, and protrudes in the radial direction of the column member 2. Yes. An abutting member 42 a that slides in contact with the surface 41 a of the rail member 41 is fixed to the tip of the slide member 42. The contact member 42a is preferably a sliding member made of, for example, synthetic fiber. Protrusions 42b and 42b are formed on both sides of the contact member 42a. The projecting portions 42b and 42b are arranged so as to sandwich the flange portion of the rail member 41, and come into contact with the side surface of the flange portion to thereby prevent the column member 2 from being lifted up.

しかして、柱部材２は、案内機構４０によってセンタリングされ、かつ、回り止めがなされた状態でリフトアップされることになる。全長（柱部材２の周面からの突出量）が異なるスライド部材４２を用意することで、異径の柱部材２にも対応可能である。   Thus, the column member 2 is lifted up in a state where it is centered by the guide mechanism 40 and is prevented from rotating. By preparing the slide member 42 having a different total length (amount of protrusion from the circumferential surface of the column member 2), the column member 2 having a different diameter can be handled.

次に、図１（Ａ）、図１（Ｂ)、図３（Ａ)及び図３（Ｂ)を参照して支持機構５０について説明する。図３（Ａ)及び図３（Ｂ)は、それぞれ、支持機構５０の平面図と側面図とを示しており、図３（Ａ）は非係合位置にある場合、図３（Ｂ)は係合位置にある場合を示している。   Next, the support mechanism 50 will be described with reference to FIGS. 1 (A), 1 (B), 3 (A), and 3 (B). 3 (A) and 3 (B) show a plan view and a side view of the support mechanism 50, respectively, and FIG. 3 (A) is in the disengaged position, FIG. 3 (B) is The case in the engaged position is shown.

支持機構５０は、構造体１０の天部に配設されており、一対の係合部材５１、５１と、係合部材５１と係合してその水平方向の移動を案内する案内部材５２と、を備える。案内部材５２は構造体１０に固定されている。   The support mechanism 50 is disposed on the top of the structure 10, and includes a pair of engaging members 51, 51, a guide member 52 that engages with the engaging member 51 and guides its horizontal movement, Is provided. The guide member 52 is fixed to the structure 10.

一対の係合部材５１、５１は互いに対向して配設され、その内側端部は柱部材２と係合する係合部を構成している。詳細には、係合部材５１は、図３（Ａ)に示すように、柱部材２から離間した非係合位置と、図３（Ｂ）に示すように柱部材２の円筒部２ａに近接した係合位置との間で水平方向に移動可能となっている。係合部材５１の移動は、複数の作業者による手動か、或いは、ジャッキ等の動力装置を用いて行うことができる。   The pair of engaging members 51, 51 are disposed to face each other, and the inner end portions thereof constitute engaging portions that engage with the column member 2. Specifically, as shown in FIG. 3A, the engaging member 51 is close to the non-engaging position separated from the column member 2 and the cylindrical portion 2a of the column member 2 as shown in FIG. It is possible to move in the horizontal direction between the engaged positions. The engagement member 51 can be moved manually by a plurality of workers, or using a power device such as a jack.

係合位置においては、係合部材５１の内側端部が柱部材２のフランジ部２ｂと上下に重なり、フランジ部２ｂが係合部材５１の内側端部に引っ掛かって係合状態となる。これにより、柱部材２が支持機構５０に吊り下げ状態で支持される。一方、非係合位置においては、係合部材５１の内側端部が柱部材２のフランジ部２ｂから離脱し、柱部材２は支持機構５０に支持されない。なお、係合部材５１の内側端部とフランジ部２ｂとの係合面積（接触面積）を大きくするため、本実施形態では内側端部が弧状をなしている。   At the engagement position, the inner end portion of the engagement member 51 overlaps with the flange portion 2b of the column member 2 vertically, and the flange portion 2b is hooked on the inner end portion of the engagement member 51 to be in an engaged state. Thereby, the pillar member 2 is supported by the support mechanism 50 in a suspended state. On the other hand, in the non-engagement position, the inner end portion of the engagement member 51 is detached from the flange portion 2 b of the column member 2, and the column member 2 is not supported by the support mechanism 50. In addition, in order to enlarge the engagement area (contact area) of the inner side edge part of the engaging member 51 and the flange part 2b, in this embodiment, the inner side edge part has comprised the arc shape.

こうして本実施形態では、支持機構５０によりリフトアップ後の柱部材２単体及びその連結体が落下しないように、支持解除可能にこれらを支持することができる。なお、本実施形態では、係合部材５１をフランジ部２ｂと係合させる構成としたが、柱部材２に対する係合部位はこれに限られず、別の部位でもよく、その場合、専用の係合部位を柱部材２に設けてもよい。   In this way, in the present embodiment, the support mechanism 50 can support the releasable pillar member 2 alone and the connected body thereof so that the support can be released so as not to fall. In the present embodiment, the engagement member 51 is engaged with the flange portion 2b. However, the engagement portion for the column member 2 is not limited to this, and may be a different portion. The part may be provided in the column member 2.

次に、図１（Ａ）及び図１（Ｂ)を参照して導入装置６０について説明する。導入装置６０は構造体１０の外部から導入空間Ｓ１内に柱部材２を導入する装置である。導入装置６０は、一対のレール部材６２、６２と、各レール部材６２に設けたトロリ６１と、を備える。   Next, the introduction device 60 will be described with reference to FIGS. 1 (A) and 1 (B).

In this embodiment, the uppermost column member is a steel frame as described above, but all the column members may be reinforced concrete as column members 110A to 110F.

連結部材１３０は柱部材１１０Ｃと柱部材１１０Ｄとの間に配設されており、ケーブルＷの一端を連結するための部材である。ケーブルＷは連結部材１３０とコンクリート基礎２００との間において複数張設される他、柱部材１２０の下端部とコンクリート基礎２００との間においても複数張設される。   The connecting member 130 is disposed between the column member 110C and the column member 110D, and is a member for connecting one end of the cable W. A plurality of cables W are stretched between the connecting member 130 and the concrete foundation 200, and a plurality of cables W are also stretched between the lower end portion of the column member 120 and the concrete foundation 200.

最下部の柱部材１１０Ａの下端部はコンクリート基礎２００に埋設されている。本実施形態では、この埋設部分における支持モデルをピン形式とし、塔状構造物１００の傾倒防止策として、ケーブルＷを設けた構成を想定している。無論、支持モデルを固定形式とし、ケーブルＷを不要とする構成も採用可能である。   The lower end of the lowermost column member 110 </ b> A is embedded in the concrete foundation 200. In the present embodiment, it is assumed that the support model in the buried portion is a pin type and the cable W is provided as a measure for preventing the tower structure 100 from being tilted. Of course, it is possible to adopt a configuration in which the support model is a fixed type and the cable W is not required.

次に、構築装置１による塔状構造物１００の構築手順について図５乃至図７を参照して説明する。塔状構造物１００の構築にあたっては、事前に塔状構造物１００の基礎となるコンクリート基礎２００を施工し、その上に構築装置１を建設する。その後、塔状構造物１００の構築を開始する。   Next, the construction procedure of the tower-like structure 100 by the construction apparatus 1 will be described with reference to FIGS. In constructing the tower-like structure 100, the concrete foundation 200 that is the foundation of the tower-like structure 100 is constructed in advance, and the construction apparatus 1 is constructed thereon. Thereafter, the construction of the tower structure 100 is started.

まず、柱部材１１０Ａ乃至１１０Ｆの中で最上部の柱部材１１０Ｆを、準備位置にあるトロリ６１に吊り下げる（図５（Ａ)）。トロリ６１への吊り下げにあたっては、上記の通り、吊り装置７０を利用して柱部材１１０を起立させ、トロリ６１に移し替えることで行うことが可能である。柱部材１１０Ｆにはスライド部材４２が事前に装着される。   First, among the column members 110A to 110F, the uppermost column member 110F is suspended from the trolley 61 in the preparation position (FIG. 5A). The suspension to the trolley 61 can be performed by raising the column member 110 using the suspension device 70 and transferring it to the trolley 61 as described above. The slide member 42 is mounted in advance on the column member 110F.

次に、トロリ６１を準備位置から導入空間Ｓ１へ移動し、柱部材１１０Ｆを導入空間Ｓ１内に導入する（図５（Ｂ））。その際、柱部材１１０Ｆと吊り架台２０とが干渉しないように吊り架台２０を導入空間Ｓ１の最下部に位置させておく。   Next, the trolley 61 is moved from the preparation position to the introduction space S1, and the column member 110F is introduced into the introduction space S1 (FIG. 5B). At that time, the suspension base 20 is positioned at the lowermost part of the introduction space S1 so that the column member 110F and the suspension base 20 do not interfere with each other.

次に、トロリ６１から吊り架台２０へ柱部材１１０Ｆの移し替えを行う（図５（Ｃ)）。詳細には、トロリ６１により柱部材１１０Ｆを降下させて吊り架台２０の載置部２３上に載置する。   Next, the column member 110F is transferred from the trolley 61 to the suspension base 20 (FIG. 5C). Specifically, the column member 110 </ b> F is lowered by the trolley 61 and placed on the placement unit 23 of the suspension base 20.

次に、スライド部材４２とレール部材４１との位置合わせを行った後、昇降機構３０により吊り架台２０を上昇させ、柱部材１１０Ｆを導入空間Ｓ１から上部空間Ｓ２へリフトアップする（図５（Ｄ））。リフトアップ中、スライド部材４２がレール部材４１を滑動することで柱部材１１０Ｆは、その位置決めがなされた状態でリフトアップされる。リフトアップ中、支持機構５０の係合部材５１は非係合位置にある。また、柱部材１１０Ｆから吊材６１ａを取り外し、トロリ６１を準備位置に戻す。   Next, after the alignment of the slide member 42 and the rail member 41 is performed, the suspension base 20 is raised by the elevating mechanism 30, and the column member 110F is lifted up from the introduction space S1 to the upper space S2 (FIG. 5D )). During the lift-up, the slide member 42 slides on the rail member 41, so that the pillar member 110F is lifted up in a state where the column member 110F is positioned. During the lift-up, the engagement member 51 of the support mechanism 50 is in the non-engagement position. Moreover, the suspension member 61a is removed from the column member 110F, and the trolley 61 is returned to the preparation position.

柱部材１１０Ｆのリフトアップは、柱部材１１０Ｆのフランジ部１１２が係合部材５１を僅かに超える位置まで行う。この位置までリフトアップすると、係合部材５１を係合位置に移動し、昇降機構３０により吊り架台２０を降下させる（図５（Ｅ））。これにより、リフトアップされた柱部材１１０Ｆは落下しないように支持機構５０に支持される。また、吊り架台２０は次の柱部材１１０Ｅの導入準備に入ると共に、トロリ６１には次の柱部材１１０Ｅが吊り下げられる。   The column member 110F is lifted up to a position where the flange portion 112 of the column member 110F slightly exceeds the engaging member 51. When lifted up to this position, the engaging member 51 is moved to the engaging position, and the lifting platform 20 is lowered by the lifting mechanism 30 (FIG. 5E). Accordingly, the lifted column member 110F is supported by the support mechanism 50 so as not to fall. In addition, the suspension base 20 starts preparation for introduction of the next column member 110E, and the next column member 110E is suspended from the trolley 61.

次に、トロリ６１を準備位置から導入空間Ｓ１へ移動し、柱部材１１０Ｅを導入空間Ｓ１内に導入し（図５（Ｆ））、トロリ６１から吊り架台２０へ柱部材１１０Ｆの移し替えを行う。続いて、柱部材１１０Ｆの下方のフランジ部１１２と、柱部材１１０Ｅの上方のフランジ部１１２とが当接する位置まで、昇降機構３０により柱部材１１０Ｅを上昇させる（図６（Ａ）)。そして、これらのフランジ部１１２をボルト−ナットで締結し、柱部材１１０Ｆと柱部材１１０Ｅとを連結する。   Next, the trolley 61 is moved from the preparation position to the introduction space S1, the pillar member 110E is introduced into the introduction space S1 (FIG. 5F), and the pillar member 110F is transferred from the trolley 61 to the suspension frame 20. . Subsequently, the column member 110E is raised by the elevating mechanism 30 to a position where the flange portion 112 below the column member 110F and the flange portion 112 above the column member 110E abut (FIG. 6A). And these flange parts 112 are fastened with a volt | bolt-nut, and the column member 110F and the column member 110E are connected.

次に、支持機構５０の係合部材５１を非係合位置に移動する。そして、柱部材１１０Ｆのフランジ部１１２がレール部材４１よりも上方に位置するように、昇降機構３０により柱部材１１０Ｅ及び１１０Ｆの連結体をリフトアップする（図６（Ｂ）)。この状態で、柱部材１２０をジブクレーン（不図示）で吊り上げ、柱部材１１０Ｆの上端に搭載し、ボルト−ナットで柱部材１１０Ｆに締結する。柱部材１２０に連結するケーブルＷはこの時点で連結しておく。   Next, the engagement member 51 of the support mechanism 50 is moved to the non-engagement position. Then, the connecting body of the column members 110E and 110F is lifted up by the elevating mechanism 30 so that the flange portion 112 of the column member 110F is positioned above the rail member 41 (FIG. 6B). In this state, the column member 120 is lifted by a jib crane (not shown), mounted on the upper end of the column member 110F, and fastened to the column member 110F with a bolt-nut. The cable W connected to the column member 120 is connected at this time.

本実施形態では、柱部材１２０についてはジブクレーンを用いることとした。しかし、柱部材１２０の吊り上げ高さは、柱部材１１０Ａ乃至１１０Ｆの連結後に搭載する場合に比べて著しく低くなるので、小型のジブクレーンで足りる。   In the present embodiment, a jib crane is used for the column member 120. However, since the lifting height of the column member 120 is significantly lower than when the column members 110A to 110F are mounted after being connected, a small-sized jib crane is sufficient.

次に、柱部材１２０、柱部材１１０Ｆ及び柱部材１１０Ｅの連結体を、昇降機構３０によりリフトアップする。リフトアップは、柱部材１１０Ｅのフランジ部１１２が係合部材５１を僅かに超える位置まで行い、その後、係合部材５１を係合位置に移動する（図６（Ｃ)）。リフトアップされた連結体は支持機構５０に支持される。柱部材１１０Ｇは、その大部分がレール部材４１の上方に露出した状態となり、レール部材４１による案内はないので、柱部材１１０Ｇに装着したスライド部材４２を順次撤去する。   Next, the connected body of the column member 120, the column member 110 </ b> F, and the column member 110 </ b> E is lifted up by the elevating mechanism 30. The lift-up is performed until the flange portion 112 of the column member 110E slightly exceeds the engaging member 51, and then the engaging member 51 is moved to the engaging position (FIG. 6C). The lifted-up connector is supported by the support mechanism 50. Most of the column member 110G is exposed above the rail member 41, and there is no guidance by the rail member 41. Therefore, the slide member 42 attached to the column member 110G is sequentially removed.

吊り架台２０は昇降機構３０により降下されて次の柱部材１１０Ｅの導入準備に入ると共に、トロリ６１には次の柱部材１１０Ｄが吊り下げられる。以降、同様にして、柱部材１１０Ａ乃至Ｄが連結されていく。   The suspension base 20 is lowered by the elevating mechanism 30 and enters the preparation for introducing the next column member 110E, and the next column member 110D is suspended from the trolley 61. Thereafter, the column members 110A to 110D are connected in the same manner.

連結部材１３０の連結は、例えば、柱部材１１０Ｃに事前に連結しておくか、或いは、柱部材１１０Ｄと柱部材１１０Ｃとの連結作業の段階（図６（Ａ)に相当）において、フランジ部１１２間に連結部材１３０の挿入スペースが形成されるように、柱部材１１０Ｃの高さを昇降機構３０により調整する。そして、連結部材１３０をこのスペースに挿入して、柱部材１１０Ｄ及び柱部材１１０Ｃの各フランジ部１１２とボルト−ナットで締結すればよい。連結部材１３０は、レール部材４１間を通過可能な大きさであり、連結体のリフトアップ時にレール部材４１と干渉することはない。   For example, the connecting member 130 is connected to the column member 110C in advance, or at the stage of connecting the column member 110D and the column member 110C (corresponding to FIG. 6A), the flange portion 112 is connected. The height of the column member 110C is adjusted by the elevating mechanism 30 so that a space for inserting the connecting member 130 is formed therebetween. Then, the connecting member 130 may be inserted into this space and fastened with bolts and nuts to the flange portions 112 of the column member 110D and the column member 110C. The connecting member 130 is sized to pass between the rail members 41 and does not interfere with the rail member 41 when the connecting body is lifted up.

全ての柱部材１１０Ａ乃至１１０Ｆ、１２０及び連結部材１３０の連結が完了すると、コンクリート基礎２００への建て込みを行う。図７（Ａ）に示すように、コンクリート基礎２００には、柱部材１１０Ａの下端部を埋設するための凹部２０１が事前に形成されている。   When all the column members 110 </ b> A to 110 </ b> F and 120 and the connection member 130 are connected, the concrete foundation 200 is built. As shown in FIG. 7A, the concrete foundation 200 is formed with a recess 201 for embedding the lower end of the column member 110A in advance.

支持機構５０の係合部材５１を係合位置に位置させて柱部材の連結体を支持した状態で、吊り架台２０の載置部２３、２３の間隔を広げ、柱部材１１０Ａと干渉しないようにする。そして、図７（Ｂ）に示すように柱部材１１０Ａの上側のフランジ部１１２の直下に載置部２３が位置するまで昇降機構３０により吊り架台２０を上昇させる。続いて、載置部２３、２３の間隔を狭くして、載置部２３上に柱部材１１０Ａのフランジ部１１２が係合可能とする。   With the engaging member 51 of the support mechanism 50 positioned at the engaging position and supporting the connecting member of the pillar member, the interval between the mounting portions 23 and 23 of the suspension base 20 is widened so as not to interfere with the pillar member 110A. To do. Then, as shown in FIG. 7B, the lifting platform 20 is raised by the lifting mechanism 30 until the mounting portion 23 is positioned directly below the flange portion 112 on the upper side of the column member 110A. Subsequently, the interval between the placement portions 23 and 23 is narrowed so that the flange portion 112 of the column member 110 </ b> A can be engaged with the placement portion 23.

この状態で支持機構５０の係合部材５１を非係合位置に位置させると、柱部材の連結体は、柱部材１１０Ａのフランジ部１１２において吊り架台２０に係合し、吊り架台２０を介して昇降機構３０で支持された状態となる。   In this state, when the engaging member 51 of the support mechanism 50 is positioned at the non-engaging position, the connecting member of the pillar member engages with the suspension base 20 at the flange portion 112 of the pillar member 110A, and the suspension member 20 is interposed via the suspension base 20. It will be in the state supported by the raising / lowering mechanism 30. FIG.

そして、図７（Ｃ）に示すように、昇降機構３０により連結体を降下させると、柱部材の連結体の下端部が凹部２０１に挿入される。その後、凹部２０１から撤去し、凹部２０１を埋める。更に、ケーブルＷを張設することで塔状構造物１００の構築が完成する。   Then, as shown in FIG. 7C, when the connecting body is lowered by the elevating mechanism 30, the lower end portion of the connecting body of the column member is inserted into the recess 201. Thereafter, the recess 201 is removed and the recess 201 is filled. Furthermore, the construction of the tower structure 100 is completed by stretching the cable W.

このように本実施形態の構築装置１によれば、昇降機構３０による吊材３０ａの巻き上げ、巻き戻しによって吊り架台２０を昇降し、柱部材のリフトアップを行うので、連続的に吊り架台２０を上昇或いは降下させることができると共に揚程を長くとることでき、より短時間での昇降が可能となる。したがって、塔状構造物を構築するにあたり、柱部材のリフトアップ作業の効率化を図ることができる。   As described above, according to the construction device 1 of the present embodiment, the suspension base 20 is lifted and lowered by lifting and unwinding the suspension member 30a by the lifting mechanism 30, and the column member is lifted up. It can be raised or lowered, and the lift can be made longer, so that it can be raised and lowered in a shorter time. Therefore, in constructing the tower-like structure, it is possible to increase the efficiency of the column member lift-up operation.

柱部材の連結体の荷重が作用する部位は、吊り架台２０及び昇降機構３０により連結体を支持する場合も、支持機構５０により支持する場合も、いずれも構造体１０の上部となるので、柱部材或いはその連結体の移し替えに際して、荷重支持点の切り替えが容易で、短時間で済む。   The portion of the column member connected to which the load acts is the upper portion of the structure 10 both when the link body is supported by the suspension base 20 and the lifting mechanism 30 and when it is supported by the support mechanism 50. When transferring a member or its connected body, it is easy to change the load support point, and it takes a short time.

継ぎ足す柱部材は、導入装置６０により外部から導入でき、その際、柱部材の位置決めは、トロリ６１によりその移動方向の位置決めを、吊材６１ａの長さによりその上下方向の位置決めを、それぞれ行うことができ、既にリフトアップされている柱部材の連結体の真下の位置に、容易に柱部材を位置させることができる。   The column member to be added can be introduced from the outside by the introduction device 60. At this time, the column member is positioned in the moving direction by the trolley 61 and in the vertical direction by the length of the suspension member 61a. The column member can be easily positioned at a position directly below the coupling member of the column member that has already been lifted up.

＜他の実施形態＞
上記実施形態では柱部材１２０についてはジブクレーンで吊り上げることにしたが、ジブクレーンが使えない場所等においては、構築装置１に柱部材１２０を吊り上げる機能を付加してもよい。図８はその一例を示す。 <Other embodiments>
In the above embodiment, the column member 120 is lifted by the jib crane. However, in a place where the jib crane cannot be used, a function of lifting the column member 120 may be added to the construction apparatus 1. FIG. 8 shows an example.

同図の例では、構造体１０の上部に設けられた枠体８０と、枠体８０に支持された昇降機構８１と、を備える。昇降機構８１はここでは電動チェーンブロックである。複数の支承部８２は不図示の支持部材を介して構造体１０に支持される。支承部８２は柱部材１２０のリフトアップの際、その移動を案内するローラ等を備える。   In the example of the figure, a frame body 80 provided on the upper portion of the structure body 10 and an elevating mechanism 81 supported by the frame body 80 are provided. Here, the lifting mechanism 81 is an electric chain block. The plurality of support portions 82 are supported by the structure 10 via a support member (not shown). The support portion 82 includes a roller or the like that guides the movement of the column member 120 when the column member 120 is lifted up.

柱部材１２０は例えば、その各部品が昇降機構８１によって構造体１０の上方へ吊り上げられて組み立てられる。柱部材１２０の中心の柱部分を吊り上げる際は支承部８２でその周面を支承しながら吊り上げることができる。   For example, each component of the column member 120 is assembled by being lifted above the structure 10 by the lifting mechanism 81. When the column portion at the center of the column member 120 is lifted, the column portion 120 can be lifted while supporting the peripheral surface by the support portion 82.

柱部材１２０の組み立てが終了すると、枠体８０、昇降機構８１、支承部８２は撤去する。そして、柱部材１１０Ｆから上記の手順と同様の手順で塔状構造物を構築していくことになる。   When the assembly of the column member 120 is completed, the frame body 80, the lifting mechanism 81, and the support portion 82 are removed. And a tower-like structure will be constructed | assembled in the procedure similar to said procedure from the column member 110F.
