Description

この発明は、複数の建物棟間に、複数段の空中構造体を、建物棟の高さ方向に間隔をあけて架設して成る建物の構築方法の技術分野に属する。 The present invention belongs to the technical field of a building construction method in which a plurality of stages of aerial structures are installed between a plurality of building ridges at intervals in the height direction of the building wing.

複数の建物棟間に空中構造体を架設して成る建物の構築方法は、例えば、本出願人による下記の特許文献１に開示されており、既に公知である。
この特許文献１に係る建物の構築方法は、同文献１の図１〜図４に示したように、要するに、建物棟１、１を構築する工程と並行して、建物棟１、１間の底部で建物棟１、１間に架設される空中構造体２の主要部を組み立て、建物棟１、１のうち空中構造体２との架設レベルまで躯体構築が完了した後に、前記空中構造体２の主要部を前記架設レベルまで上昇させて建物棟１の躯体へ定着させ、しかる後、建物棟１、１と空中構造体２を完成させる方法である（詳しくは、同文献１の請求項１を参照）。
この構築方法によれば、建物棟１、１の躯体を空中構造体２の架設レベルまで構築した後に、建物棟１、１間に空中構造体２の架設作業を開始する技術と比して、建物棟１、１の躯体構築と並行して空中構造体２の主要部の組み立て作業を行うので作業効率がよく、工期を短縮できる。また、空中構造体２の主要部を地上で組み立てるので、危険な高所作業をなくして、大幅に省力化でき、作業性に優れているし、安全性が高い。さらに、空中構造体２の主要部を建物棟１、１に定着したのち、この空中構造体２を完成させる作業を、当該主要部を足場や作業床として利用できるので、特別な足場や作業床を仮設する必要もないから仮設作業を減じて、合理的、且つ経済的でもある（同文献１の段落[0002]、[0005]、及び[0006]を参照）。 A building construction method in which an aerial structure is constructed between a plurality of building buildings is disclosed in, for example, the following Patent Document 1 by the present applicant, and is already known.
As shown in FIGS. 1 to 4 of the document 1, the building construction method according to Patent Document 1 is basically between the building buildings 1 and 1 in parallel with the process of building the building buildings 1 and 1. After the main part of the aerial structure 2 constructed between the building ridges 1 and 1 is assembled at the bottom, and the building construction is completed up to the construction level with the aerial structure 2 in the building ridges 1 and 1, the aerial structure 2 The main part of the building is raised to the erection level and fixed to the building building 1, and then the building building 1, 1 and the aerial structure 2 are completed (specifically, claim 1 of the document 1). See).
According to this construction method, compared to the technique of starting the construction work of the aerial structure 2 between the building buildings 1 and 1 after the building of the building ridges 1 and 1 is constructed up to the construction level of the aerial structure 2, Since the main part of the aerial structure 2 is assembled in parallel with the building construction of the building buildings 1 and 1, work efficiency is good and the construction period can be shortened. In addition, since the main part of the aerial structure 2 is assembled on the ground, it is possible to eliminate dangerous high-altitude work, greatly reduce labor, and is excellent in workability and high in safety. Furthermore, after fixing the main part of the aerial structure 2 to the buildings 1 and 1, the work to complete the aerial structure 2 can be used as a scaffold or work floor. Therefore, the temporary work is reduced, and it is rational and economical (see paragraphs [0002], [0005], and [0006] of the same document 1).

ところで、特許文献１には、複数の建物棟１、１間に、複数段の空中構造体２…を建物棟１、１の高さ方向に間隔をあけて架設して成る建物の構築方法も、同文献１の段落[0008]に〔別実施例〕として開示されている（同文献１の図５と図６を参照）。
この建物の構築方法は、先ず、建物棟１、１を構築する工程と並行して、建物棟１、１間の底部で建物棟１、１間の上端部に架設される空中構造体２の主要部を組み立て、建物棟１、１のうち空中構造体２との架設レベルまで躯体構築が完了した後に、前記構造物２の主要部を前記架設レベルまで上昇させて建物棟１の躯体へ定着させ、次いで、建物棟１、１間の底部で建物棟１、１間の中間部に架設される空中構造体２を主要部まで組み立て、前記空中構造体２の主要部を建物棟の中間部の架設レベルまで上昇させて建物棟１の中間部の躯体へ定着させることにより、複数の建物棟間に複数段（図示例では２段）の空中構造体を、建物棟の高さ方向に間隔をあけて架設して成る建物を構築する技術である。 By the way, in Patent Document 1, there is also a building construction method in which a plurality of aerial structures 2... Are installed between a plurality of building buildings 1 and 1 at intervals in the height direction of the building buildings 1 and 1. The document [1] is disclosed as [another embodiment] in paragraph [0008] (see FIGS. 5 and 6 of the document 1).
In the building construction method, first, in parallel with the process of constructing the building ridges 1, 1, the aerial structure 2 constructed on the upper end between the building ridges 1, 1 is constructed at the bottom between the building ridges 1, 1. After the main part is assembled and the building construction is completed up to the construction level with the aerial structure 2 of the building buildings 1 and 1, the main part of the structure 2 is raised to the construction level and fixed to the building 1 building Next, the aerial structure 2 constructed in the middle part between the building buildings 1 and 1 is assembled to the main part at the bottom part between the building buildings 1 and 1, and the main part of the aerial structure 2 is assembled to the middle part of the building building. By raising the building level to the middle of the building building 1 and fixing it to the building in the middle of the building building, a plurality of (two in the illustrated example) aerial structures are spaced in the height direction of the building building. This is a technology for constructing a building that is constructed by opening the door.

特許第３１１５９４２号公報Japanese Patent No. 3115942

上記特許文献１に係る建物の構築方法によると、一段の空中構造体２を建物棟１、１間へ架設する場合は作業効率良く行える。しかし、２段以上の複数段の空中構造体２を建物棟１、１間へ架設する場合は、上記したように、最上段に架設する空中構造体２から最下段に架設する空中構造体２へ順に定着させる手法で実施するから、作業効率の観点で、下記する点が懸念される。
すなわち、建物棟１、１の躯体構築を、最上段に架設する空中構造体２の架設レベルまで予め構築しておかねばならない。例えば同文献１の図１、図５に示されたように、最上段の空中構造体２を建物棟１、１の頂部に架設する場合は、建物棟１、１の躯体構築を構築予定の高さまでほぼ完成させておかねばならない。
よって、建物棟１、１の躯体構築と並行して組み立て作業を行えるのは、最上段に架設する空中構造体２のみで、以下に架設する他の空中構造体２…は、建物棟１、１の躯体構築がほぼ完了しているにも拘わらず、建物棟１、１間の底部でその主要部を組み立て、架設レベルまで上昇させて建物棟１の躯体へ定着させて当該主要部を空中構造体として完成させる作業を、架設する空中構造体２…の段数に応じて繰り返し行わねばならなかった。
また、これに伴い、当該空中構造体２…を架設レベルへ定着させるまでの一連の作業が完了するまで、建物棟１、１間の底部の施工（例えば、外構仕上げ工事）に着手することができなかった。
以上、要するに、上記特許文献１に係る建物の構築方法によると、２段以上（複数段）の空中構造体２…を建物棟１、１間へ架設する場合は種々の問題があり、作業効率良く行えるとは云えず、改善の余地が残されている。 According to the building construction method according to Patent Document 1 described above, when the one-stage aerial structure 2 is installed between the building ridges 1 and 1, work efficiency can be improved. However, when two or more stages of aerial structures 2 are installed between the building ridges 1 and 1, as described above, the aerial structure 2 is installed from the aerial structure 2 installed at the uppermost stage to the lowermost stage. Therefore, the following points are concerned from the viewpoint of work efficiency.
That is, the building construction of the building buildings 1 and 1 must be constructed in advance up to the construction level of the aerial structure 2 constructed on the uppermost stage. For example, as shown in FIGS. 1 and 5 of the same document 1, when the uppermost aerial structure 2 is installed on the top of the buildings 1 and 1, the building construction of the buildings 1 and 1 is scheduled to be constructed. It must be almost completed to the height.
Therefore, only the aerial structure 2 installed on the uppermost stage can be assembled in parallel with the building construction of the building buildings 1 and 1, and the other aerial structures 2 installed below are the building building 1, In spite of the construction of the main building 1 being almost completed, the main part is assembled at the bottom between the building ridges 1 and 1 and is raised to the erection level to be fixed to the building 1 building. The work to complete as a structure had to be repeated according to the number of steps of the aerial structures 2.
As a result, construction of the bottom part between the building buildings 1 and 1 (for example, exterior finishing work) should be started until a series of operations until the aerial structures 2 are fixed to the construction level is completed. I could not.
In short, according to the building construction method according to Patent Document 1, there are various problems in installing two or more (multiple) aerial structures 2... It can't be done well, but there is room for improvement.

本発明の目的は、複数の建物棟間に、２段以上（複数段）の空中構造体を、建物棟の高さ方向に間隔をあけて架設して成る建物を、複合工程により、作業効率良く合理的に構築することが可能な、経済性に優れた建物の構築方法を提供することにある。 The object of the present invention is to improve the work efficiency of a building comprising two or more (multi-stage) aerial structures between a plurality of building ridges at intervals in the height direction of the building ridge by a complex process. The object is to provide a method for constructing a building that can be constructed reasonably well and that is excellent in economic efficiency.

前記建物棟１は、一例として、柱、梁の躯体が鉄骨造り、或いは鉄筋コンクリート造りで、床がサイト成形のＰＣ版で、外装がカーテンウォールの高層、或いは、超高層の構造体で実施している。ちなみに、本実施例では、建物棟１の幅寸（敷地面積）が２０ｍ×２０ｍ程度で、高さが１４０ｍ（４２階建て）程度と、アスペクト比が７程度の高層の建物棟１を想定しているが、低層の建物棟でも勿論同様に実施可能である。また、本実施例１では、図２Ａ、Ｂに示したように、２棟の建物棟１を、平面視で、左右対称な大きさ、及び配置で構築しているがこれに限定されず、後の実施例２で説明するように、３棟以上でも実施できる（図４、図１１参照、請求項４記載の発明）。 As an example, the building ridge 1 is constructed with a pillar or beam housing made of steel or reinforced concrete, a floor is a site-molded PC version, and the exterior is a high-rise or super-high-rise structure with curtain walls. Yes. By the way, in this embodiment, the building building 1 is assumed to be a high-rise building building 1 having a width dimension (site area) of about 20 m × 20 m, a height of about 140 m (42 stories), and an aspect ratio of about 7. However, it can of course be similarly applied to low-rise buildings. In the first embodiment, as shown in FIGS. 2A and 2B, the two building ridges 1 are constructed with symmetrical sizes and arrangements in plan view, but not limited thereto. As will be described later in Example 2, the invention can be implemented in three or more buildings (see FIGS. 4 and 11, the invention described in claim 4).

前記第１段目〜第３段目の空中構造体１０、２０、３０はそれぞれ、本実施例ではトラス構造等の鉄骨造りをベースに直方体状に形成しているが、建物棟１、１間に架設され支持されることが可能な大きさ（形状）と剛性を有する構造であれば種々のバリエーションで実施可能である。例えば、本出願人が先に出願した特願２００６−２５４６４３の段落[0019]、及び特願２００６−２５４６７７の段落[0018]に開示したような、下弦材の両端部（或いは一端部）に相当する位置にダンパー部材を設けたトラス構造でも実施可能である。勿論、上記特許文献１で開示したような、鉄骨梁、鉄骨柱、及び斜材鉄骨等を組み合わせて成り、中央部に上下に貫通する環状等の孔を形成した構造でも実施可能である。この空中構造体１０…は、完成後、通路、或いは居住者の憩いの空間等に供される。
また、図示例に係る前記第１段目〜第３段目の空中構造体１０、２０、３０は、建物棟１、１間の高さ方向に所定の間隔をあけて３段架設して実施しているが、２段でも実施できるし、４段以上でも実施できる。ちなみに、本実施例では、第１段目の空中構造体１０を３７階部分に架設し、第２段目の空中構造体２０を２６階部分に架設し、第３段目の空中構造体３０を１５階部分に架設した場合を想定している。 The aerial structures 10, 20, 30 of the first to third stages are each formed in a rectangular parallelepiped shape based on a steel structure such as a truss structure in this embodiment. As long as the structure has a size (shape) and rigidity capable of being installed and supported on the hood, it can be implemented in various variations. For example, it corresponds to both end portions (or one end portions) of the lower chord material as disclosed in paragraph [0019] of Japanese Patent Application No. 2006-254463 and paragraph [0018] of Japanese Patent Application No. 2006-254677 filed earlier by the present applicant. It is also possible to implement a truss structure in which a damper member is provided at the position. Of course, the present invention can also be implemented by a structure in which a steel beam, a steel column, a diagonal steel frame, and the like are disclosed in Patent Document 1 and an annular hole or the like penetrating vertically is formed in the central portion. The aerial structures 10 are used for a passage or a resident's rest space after completion.
The first to third aerial structures 10, 20, and 30 according to the illustrated example are installed in three stages at predetermined intervals in the height direction between the building buildings 1 and 1.

Incidentally, the means for raising the main part 10a of the first-stage aerial structure 10 is not limited to this, and it can be implemented by means as described in Example 2 later, or a so-called push-up method (aerial structure). It is also possible to implement by a means of pushing up the main parts 10a ... from below to the upper part (for example, a hydraulic jack) while supporting the main parts 10a ... of the bodies 10 ... from below.
In addition, in the present embodiment, the method of presumably attaching the main portion 10a of the first-stage aerial structure 10 to the housing of the building ridge 1 is an H-section steel that constitutes the upper chord member and the lower chord member of the truss structure, etc. The end of the steel member is temporarily tightened to the steel column or the steel beam constituting the housing of the corresponding building 1 with a bolt. In the following steps, the same process is performed when the main parts 10a of the aerial structures 10 are assumed to be attached to the housing of the building 1.

前記（ハ）の工程について、第２段目の空中構造体２０の主要部２０ａを、前記主要部１０ａと同様に、建物棟１、１間の底部の架台２上で、Ｈ形鋼等の鉄骨部材により、少なくとも建物棟１、１間に架設され支持されることが可能な大きさ（形状）と剛性を有するトラス構造を組み立てる。 In the step (c), the main part 20a of the second-stage aerial structure 20 is made of H-section steel or the like on the base 2 at the bottom between the building buildings 1 and 1 in the same manner as the main part 10a. A truss structure having a size (shape) and rigidity capable of being installed and supported at least between the building buildings 1 and 1 is assembled by the steel frame member.

前記（ニ）の工程について、前記空中構造体１０、２０の主要部１０ａ、２０ａをそれぞれ、順に第２の架設レベルＨ_２、第１の架設レベルＨ_１まで上昇させる手段は、上述した第１段目の空中構造体１０を上昇させる手段とほぼ同様である。即ち、図示は省略するが、前記主要部１０ａの四隅にバランスよく設けた被吊り点にワイヤを取り付け、建物棟１、１の躯体における上端部に設けた井桁状の架台に取り付けた滑車装置に前記ワイヤを巻き掛けた後、当該主要部１０ａの仮定着状態を解除してフリーとし、しかる後、地上等に設置したウインチ７で前記ワイヤ４を巻き取ることにより、前記第１段目の空中構造体１０の主要部１０ａを前記架設レベルＨ_２までリフトアップして建物棟１、１の躯体に仮定着させる。次いで、地上で組み立てた前記主要部２０ａの四隅にバランスよく設けた被吊り点にワイヤを取り付け、前記滑車装置に前記ワイヤを巻き掛け、前記ウインチで前記ワイヤを巻き取ることにより、前記主要部１０ａを前記架設レベルＨ_１までリフトアップして建物棟１、１の躯体に仮定着させる（図１Ｄ参照）。なお、前記第１段目の空中構造体１０の主要部１０ａを第１の架設レベルＨ_１までリフトアップした場合と同様に、架台２、滑車装置、及びこれを支持する井桁状の架台、並びにガイドレールは事後に撤去する。 In the step (d), the means for raising the main portions 10a and 20a of the aerial structures 10 and 20 to the second erection level H ₂ and the first erection level H ₁ , respectively, in order This is almost the same as the means for raising the aerial structure 10 at the stage. In other words, although not shown in the drawings, a pulley is attached to a suspended point provided in a well-balanced manner at the four corners of the main part 10a and attached to a cross-girder-like gantry provided at the upper end of the building of the buildings 1 and 1. After the wire is wound, the assumed wearing state of the main part 10a is released to make it free, and then the wire 4 is wound up by the winch 7 installed on the ground or the like, whereby the first-stage air the main portion 10a of the structure 10 lifted up until the erection level H ₂ is temporarily fixed to the skeleton of the building building 1,1. Next, wires are attached to suspension points provided in a well-balanced manner at the four corners of the main part 20a assembled on the ground, the wire is wound around the pulley device, and the wire is wound by the winch, thereby the main part 10a. lifted up until the erection level H ₁ is temporarily fixed to the skeleton of the building building 1,1 (see FIG. 1D). As in the case where the main portion 10a of the first-stage aerial structure 10 is lifted up to the _first erection level H1, the gantry 2, the pulley device, and the cross-girder-like gantry supporting the gantry, The guide rail will be removed after the fact.

前記（ホ）の工程について、図１Ｅに示したように、建物棟１、１の躯体構築と並行して、第３段目の空中構造体３０の主要部３０ａを、建物棟１、１間の底部の架台２上で、前記主要部１０ａ、２０ａと同様に、Ｈ形鋼等の鉄骨部材により、少なくとも建物棟１、１間に架設され支持されることが可能な大きさ（形状）と剛性を有するトラス構造を組み立てる。 In the step (e), as shown in FIG. 1E, in parallel with the building construction of the buildings 1 and 1, the main part 30a of the third-stage aerial structure 30 is moved between the buildings 1 and 1. The size (shape) that can be laid and supported at least between the building ridges 1 and 1 by a steel frame member such as H-shaped steel, similar to the main portions 10a and 20a. Assemble the truss structure with rigidity.

また、図１Ｆに示したように、前記空中構造体１０、２０、３０の主要部１０ａ、２０ａ、３０ａをそれぞれ、順に第３の架設レベルＨ_３、第２の架設レベルＨ_２、第１の架設レベルＨ_１まで上昇させる手段は、上述した第１段目の空中構造体１０を第１の架設レベルＨ_１まで上昇させる手段とほぼ同様である。
即ち、図示は省略するが、前記空中構造体の１０の主要部１０ａの四隅にバランスよく設けた被吊り点にワイヤを取り付け、建物棟１、１の躯体における上端部に設けた井桁状の架台に取り付けた滑車装置に前記ワイヤを巻き掛けた後、当該主要部１０ａの仮定着状態を解除してフリーとし、しかる後、地上等に設置したウインチで前記ワイヤを巻き取ることにより、前記第１段目の空中構造体１０の主要部１０ａを前記第３の架設レベルＨ_３まで上昇させて建物棟１、１の躯体に仮定着させる。
次いで、前記空中構造体２０の主要部２０ａの四隅にバランスよく設けた被吊り点にワイヤを取り付け、前記滑車装置に前記ワイヤを巻き掛けた後、当該主要部２０ａの仮定着状態を解除してフリーとし、しかる後、前記ウインチで前記ワイヤを巻き取ることにより、前記第２段目の空中構造体２０の主要部２０ａを前記第２の架設レベルＨ_２まで上昇させて建物棟１、１の躯体に仮定着させる。
次いで、地上で組み立てた前記空中構造体３０の主要部３０ａの四隅にバランスよく設けた被吊り点にワイヤを取り付け、前記滑車装置に前記ワイヤを巻き掛け、前記ウインチで前記ワイヤを巻き取ることにより、前記主要部３０ａを前記第１の架設レベルＨ_１まで上昇させて建物棟１、１の躯体に仮定着させる。 Further, as shown in FIG. 1F, the main portions 10a, 20a, 30a of the aerial structures 10, 20, 30 are respectively connected to the third erection level H ₃ , the second erection level H ₂ , the first erection level, respectively. means for raising up erection level H ₁ is substantially similar to the means for raising the first stage aerial structure 10 described above to the first erection level H _1.
In other words, although not shown in the drawing, a wire is attached to the suspended points provided in a well-balanced manner at the four corners of the 10 main parts 10a of the aerial structure, and the cross-girder-like gantry provided at the upper end of the building of the building ridges 1 and 1 After the wire is wound around the pulley device attached to the main body 10a, the assumed wearing state of the main portion 10a is released to make it free, and then the first wire is wound by a winch installed on the ground or the like, thereby The main part 10a of the aerial structure 10 at the stage is raised to the _third erection level H3 and is assumed to be attached to the buildings of the building buildings 1 and 1.
Next, wires are attached to suspension points provided in a well-balanced manner at the four corners of the main part 20a of the aerial structure 20, and after the wire is wound around the pulley device, the assumed wearing state of the main part 20a is released. After that, the main part 20a of the second-stage aerial structure 20 is raised to the _second erection level H2 by winding the wire with the winch so that the buildings 1 and 1 Assumed to be attached to the body.
Next, by attaching wires to suspension points provided in a well-balanced manner at the four corners of the main part 30a of the aerial structure 30 assembled on the ground, winding the wire around the pulley device, and winding the wire with the winch The main part 30a is raised to the _first erection level H1 and is assumed to be attached to the buildings of the building buildings 1 and 1.

そして、前記第３段目の空中構造体３０の主要部３０ａを建物棟１、１間の前記第１の架設レベルＨ_１に仮定着させた後、図２Ａ、Ｂに示したように、建物棟１、１を構築予定の高さまで完成させると共に、仮定着したすべての空中構造体１０、２０、３０の主要部１０ａ、２０ａ、３０ａを当該部位で本定着させ、当該主要部１０ａ、２０ａ、３０ａを足場や作業床として利用し、各空中構造体１０…の各主要部１０ａ…以外の残りの部分をそれぞれ施工して、すべての空中構造体１０、２０、３０を完成させるのである。
前記各主要部１０ａ…を、建物棟１の躯体に本定着させる手法は、一例として、トラス構造の上弦材及び下弦材を構成するＨ形鋼等の鉄骨部材の端部を、対応する建物棟１の躯体を構成する鉄骨柱、或いは鉄骨梁に、ボルト又は溶接等の接合手段で強固に剛結して連結する。 After said third stage main portion 30a of the aerial structure 30 is temporarily fixed to the first erection level H ₁ between the building Building 1,1, as shown FIG. 2A, the B, building The ridges 1 and 1 are completed to the height to be built, and the main parts 10a, 20a, and 30a of all the aerial structures 10, 20, and 30 that are supposedly attached are permanently fixed at the corresponding parts, and the main parts 10a, 20a, and 30a is used as a scaffold or work floor, and the remaining portions other than the main portions 10a of each aerial structure 10 are respectively constructed to complete all the aerial structures 10, 20, 30.
The method of permanently fixing each of the main parts 10a to the frame of the building ridge 1 is, for example, the end of the steel member such as H-shaped steel constituting the upper chord material and the lower chord material of the truss structure corresponding to the building ridge. It is firmly connected to a steel column or a steel beam constituting one housing by a joining means such as a bolt or welding.

ちなみに、建物棟１、１間に架設する空中構造体の段数が２段の場合は、前記（ホ）に係る（ハ）及び（ニ）の工程は不要であり、前記（イ）〜（ニ）の工程を経た後に、複数の建物棟１、１を完成させると共に、前記空中構造体１０、２０を完成させるための仕上げ工程（防水工事、植栽工事等を含む。以下同じ。）を行う。また、前記空中構造体の段数が３段以上であれば、前記（イ）〜（ニ）の工程を経て、前記（ホ）の工程を当該空中構造体の段数に応じて繰り返した後に、複数の建物棟１、１を完成させる共に、前記空中構造体１０…を完成させるための仕上げ工程を行うのである。 Incidentally, when the number of steps of the aerial structure erected between the building ridges 1 and 2 is two, the steps (c) and (d) relating to the above (e) are not necessary. ), A plurality of building ridges 1 and 1 are completed, and a finishing process (including waterproofing work, planting work, etc.) for completing the aerial structures 10 and 20 is performed. . In addition, if the number of stages of the aerial structure is three or more, after repeating the steps (a) to (d) and repeating the process (e) according to the number of stages of the aerial structure, The building buildings 1 and 1 are completed, and a finishing process for completing the aerial structures 10 is performed.

したがって、上記構成の建物の構築方法によれば、建物棟の躯体を空中構造体の架設レベルまで構築した後に、建物棟間に空中構造体の架設作業を開始する技術と比して、建物棟１、１の躯体構築と並行して、第１段目〜第３段目の空中構造体１０、２０、３０の各主要部１０ａ、２０ａ、３０ａの組み立て作業を行うので作業効率が非常によく、工期を大幅に短縮できる。また、すべての空中構造体１０、２０、３０の主要部１０ａ、２０ａ、３０ａを地上等の底部で組み立てるので、危険な高所作業を大幅に軽減できる。さらに、前記各主要部１０ａ…を建物棟１、１に定着したのち、この空中構造体１０…を完成させる作業を、当該各主要部１０ａ…を足場や作業床として利用できるので、特別な足場や作業床を仮設する必要もないから仮設作業を減じて、合理的、且つ経済的である。 Therefore, according to the construction method of the building having the above configuration, the building building is compared with the technique of starting the construction work of the aerial structure between the building buildings after the building body is built to the level of the aerial structure. In parallel with the construction of the first and first housings, the main parts 10a, 20a, 30a of the first to third stage aerial structures 10, 20, 30 are assembled so that the work efficiency is very good. The construction period can be greatly shortened. Moreover, since the main parts 10a, 20a, and 30a of all the aerial structures 10, 20, and 30 are assembled at the bottom part such as the ground, dangerous high place work can be greatly reduced. Further, after fixing the main parts 10a to the building ridges 1 and 1, the work to complete the aerial structure 10 can be used as a scaffold or work floor. Since there is no need to install a temporary work floor, the temporary work is reduced, which is rational and economical.

また、上記構成の建物の構築方法によれば、上記特許文献１に開示された技術と比して、建物棟１、１の躯体構築と並行して、第１段目の空中構造体１０の主要部１０ａのみならず、第２、第３段目の空中構造体２０、３０の各主要部２０ａ、３０ａの組み立て作業を行い得るので、作業効率が非常に良く、合理的であり、工期を大幅に短縮できる。これに伴い、コスト削減に大きく寄与する。 Moreover, according to the building construction method having the above-described configuration, the first-stage aerial structure 10 is parallel to the building construction of the building buildings 1 and 1 as compared with the technique disclosed in Patent Document 1. Since not only the main part 10a but also the main parts 20a and 30a of the second and third stage aerial structures 20 and 30 can be assembled, the work efficiency is very good, reasonable, and the construction period is long. Can be greatly shortened. This greatly contributes to cost reduction.

図４は、請求項１に記載した建物の構築方法の異なる実施例を示している。この建物の構築方法は、上記実施例１と比して、前記建物棟１と同形・同大の建物棟１を３棟設けて実施していること、及びこれに伴い建物棟１、１、１間に架設する第１段目〜第３段目の
空中構造体１０、２０、３０とその主要部１０ａ、２０ａ、３０ａの形状を平面視で、ほぼ六角形状に形成していること、並びに前記各主要部１０ａ、２０ａ、３０ａを上昇させる手段、が主に相違する。
よって、この実施例２に係る建物の構築方法の手順は、上述した実施例１に係る前記（イ）〜（ホ）の工程と同様の工程で行うので、図１Ａ〜Ｆの工程図を援用すると共に、その説明を適宜割愛する。 FIG. 4 shows a different embodiment of the building construction method described in claim 1.

A lifting material 13 such as a steel wire (or PC steel bar) is attached, and a position higher than the construction level H ₁ of the first-stage aerial structure 10 between the building buildings 1, 1, 1 (the upper ends of the building buildings 1, 1 A lifting beam 8 having lift-up jacks J ₁ and J ₂ mounted between them and temporarily lifting the lifting member 13 with the lift-up jacks J ₁ and J ₂ . lift until the erection level _{H 1} of 1 Tsu is up (the invention of claim 3, wherein).

前記主要部１０ａに被吊り点Ｔ_１、Ｔ_２を設ける手法として、本実施例では、図５と図７Ｃに示したように、当該主要部１０ａの構成要素である、隣接する建物棟１、１間に設けた３体のトラス構造１２の上弦材同士を連結する所定の水平材（鉄骨小梁）１２ａ（図７Ｃ参照）の中央部を被吊り点Ｔ_１、Ｔ_２としている。当該被吊り点Ｔ_１、Ｔ_２部分は、プレートにて加工して形成し、ＰＣ鋼線（又はＰＣ鋼棒）の端部と緊結している。また、前記被吊り点Ｔ_１、Ｔ_２部分は、図７Ｃに示したように、架構の変形を防止するべく、倒立Ｖ字形状に形成した補強材１４で補強しておくことが好ましい。 As a method of providing the suspended points T ₁ and T ₂ in the main part 10a, in this embodiment, as shown in FIGS. 5 and 7C, adjacent building ridges 1, which are constituent elements of the main part 10a, The central portions of a predetermined horizontal member (steel beam) 12a (see FIG. 7C) that connects the upper chord members of the three truss structures 12 provided between 1 are defined as suspended points T ₁ and T ₂ . The suspended points T ₁ and T ₂ are formed by processing with a plate and are tightly connected to the end of a PC steel wire (or PC steel rod). Further, as shown in FIG. 7C, the suspended points T ₁ and T ₂ are preferably reinforced with a reinforcing material 14 formed in an inverted V shape so as to prevent deformation of the frame.

建物棟１、１、１間の上端部に仮設するリフティングビーム８は、図６に示したように、長尺と短尺の鋼製プレート（又はＨ形鋼等の形鋼）を組み合わせて細長い井桁状に形成してなり、平面視で、前記トラス構造１２の被吊り点Ｔ_１、Ｔ_２に対応する配置を通るように載置している。このリフティングビーム８には、前記被吊り点Ｔ_１、Ｔ_２にそれぞれ対応するべく、平面視でほぼ一致する位置に、リフトアップ用ジャッキＪ_１、Ｊ_２を搭載している。このリフトアップ用ジャッキＪ_１、Ｊ_２はそれぞれ、リフティングビーム８の長手方向に沿って位置決め可能な構成で実施されている。
なお、前記建物棟１の上端部における前記リフティングビーム８を載置する部位（例えば、鉄骨梁）は、図示は省略するが、補強材で補強しておくことが好ましい。また、本実施例に係るリフトアップ用ジャッキＪ_１、Ｊ_２は、所謂ダブルツインジャッキで実施しているがこれに限定されず、センターホールジャッキでも同様に実施可能である。
ちなみに、図６中の符号１１は、作業者のための安全通路を示しており、リフティングビーム８に沿って設けている。 As shown in FIG. 6, the lifting beam 8 temporarily installed at the upper end between the building buildings 1, 1, 1 is a long and narrow girder by combining long and short steel plates (or shaped steel such as H-shaped steel). In the plan view, the truss structure 12 is placed so as to pass through the arrangement corresponding to the suspended points T ₁ and T ₂ . Lifting jacks J ₁ and J ₂ are mounted on the lifting beam 8 at positions substantially coincident with each other in plan view so as to correspond to the suspended points T ₁ and T ₂ , respectively. The lift-up jacks J ₁ and J ₂ are each configured to be positioned along the longitudinal direction of the lifting beam 8.
In addition, although illustration is abbreviate | omitted, the site | part (for example, steel beam) which mounts the said lifting beam 8 in the upper end part of the said building ridge 1 is preferably reinforced with a reinforcing material. Further, the lift-up jacks J ₁ and J _{2 according} to the present embodiment are implemented by so-called double twin jacks, but are not limited thereto, and can also be implemented by a center hole jack.
Incidentally, reference numeral 11 in FIG. 6 indicates a safety passage for the operator, and is provided along the lifting beam 8.

即ち、図５〜図７に係る前記主要部１０ａ（或いは２０ａ、３０ａ）をリフトアップする手法は、先ず、主要部１０ａ全体をバランス良く吊上げることが可能な部位（本実施例では計６箇所）を予め算出し、当該部位近傍に位置するトラス構造１２の前記水平材１２ａの中央部を被吊り点Ｔ_１、Ｔ_２とする。次いで、前記リフティングビーム８を、当該トラス構造１２の配置に対応するように建物棟１、１の上端部間に仮設する。そして、リフティングビーム８に搭載したリフトアップ用ジャッキＪ_１、Ｊ_２を、所定の部位に位置決めすることにより、平面視で、前記水平材１２ａに設けた被吊り点Ｔ_１、Ｔ_２と、リフトアップ用ジャッキＪ_１、Ｊ_２とをそれぞれほぼ一致させるのである。 That is, the method of lifting up the main portion 10a (or 20a, 30a) according to FIGS. 5 to 7 is first a portion where the entire main portion 10a can be lifted in a balanced manner (in this embodiment, a total of six locations). ) Is calculated in advance, and the central part of the horizontal member 12a of the truss structure 12 located in the vicinity of the part is defined as the suspended points T ₁ and T ₂ . Next, the lifting beam 8 is temporarily installed between the upper ends of the building buildings 1 and 1 so as to correspond to the arrangement of the truss structure 12. Then, the lift-up jacks J ₁ and J ₂ mounted on the lifting beam 8 are positioned at predetermined portions, so that the suspended points T ₁ and T ₂ provided on the horizontal member 12a in plan view and the lift The up jacks J ₁ and J ₂ are substantially matched with each other.

かくして、図７Ａ、Ｂに示したように、安定した状態で、前記第１段目の空中構造体１０の主要部１０ａを、所定の第１の架設レベルＨ_１（図１Ｂ参照）、第２の架設レベルＨ_２（図１Ｄ参照）、或いは第３の架設レベルＨ_３（図１Ｆ参照）までリフトアップすることができるのである。
同様の手法で、前記第２段目の空中構造体２０の主要部２０ａもまた、安定した状態で、所定の第１の架設レベルＨ_１、（図１Ｄ参照）、及び第２の架設レベルＨ_２（図１Ｆ参照）までリフトアップすることができ、前記第３段目の空中構造体３０の主要部３０ａも、安定した状態で、所定の第１の架設レベルＨ_１（図１Ｆ参照）までリフトアップすることができるのである。 Thus, as shown in FIGS. 7A and 7B, in a stable state, the main portion 10a of the first-stage aerial structure 10 is moved to a predetermined first construction level H ₁ (see FIG. 1B), second It is possible to lift up to the installation level H ₂ (see FIG. 1D) or the third installation level H ₃ (see FIG. 1F).
In the same manner, the main portion 20a of the second-stage aerial structure 20 is also in a stable state with a predetermined first erection level H ₁ (see FIG. 1D), and second erection level H. ₂ (see FIG. 1F), and the main portion 30a of the third-stage aerial structure 30 is also in a stable state up to a predetermined first construction level H ₁ (see FIG. 1F). You can lift up.

なお、本実施例２では、被吊り点を６箇所で実施しているがこれに限定されるものではなく、主要部１０ａを安定した状態でリフトアップできることを条件に、適宜増減して実施することができ、これに応じて、リフティングビーム８、及びリフトアップ用ジャッキＪ_１、Ｊ_２の使用数量も適宜増減して実施する。 In addition, in the present Example 2, although the suspended point is implemented in six places, it is not limited to this, It implements by increasing / decreasing suitably on condition that the main part 10a can be lifted up in the stable state. In accordance with this, the amount of the lifting beam 8 and the lift-up jacks J ₁ and J ₂ used is appropriately increased and decreased.

したがって、上記構成の建物の構築方法によれば、上記実施例１と同様の作用効果を奏することができることに加え、空中構造体１０…の主要部１０ａ…をバランス良く吊上げ可能なように、被吊り点Ｔ_１、Ｔ_２、及び吊り点（リフトアップ用ジャッキＪ_１、Ｊ_２）の数を容易に増減できると共に、それらの位置を調整できるので、当該主要部１０ａ…がより広大で大掛かりな構造となったとしても、安定した状態でリフトアップ作業を行うことができるので、安全性の向上に寄与する。 Therefore, according to the building construction method having the above configuration, in addition to being able to achieve the same operational effects as those of the first embodiment, the main parts 10a of the aerial structures 10 can be lifted in a balanced manner. The number of suspension points T ₁ and T ₂ and the number of suspension points (lift-up jacks J ₁ and J ₂ ) can be easily increased and decreased, and their positions can be adjusted, so that the main part 10a is larger and larger. Even if it becomes a structure, the lift-up operation can be performed in a stable state, which contributes to an improvement in safety.

なお、このリフトアップ用ジャッキＪ_１、Ｊ_２を搭載したリフティングビーム８を建物棟１、１、１間の上端部に仮設してリフトアップする手段について、被吊り点Ｔ_１、Ｔ_２を形成する手段はこれに限定されない。
例えば、図８〜図１０に示したように、各トラス構造１２の上端部（上弦材）に、その長手方向に直交する方向に所定の間隔をあけて２体の繋ぎ材９を取り付け、同繋ぎ材９上に、被吊り点Ｔ_１（Ｔ_２）を、スライド自在な構成に設けて実施することもできる。この手法によれば、主要部１０ａ全体をバランス良く吊上げることが可能な部位とほぼ一致する位置に、被吊り点Ｔ_１（Ｔ_２）を形成することができる利点がある。 In addition, suspended points T ₁ and T ₂ are formed as means for temporarily lifting the lifting beam 8 mounted with the lift-up jacks J ₁ and J ₂ at the upper end between the building ridges 1, ₁ , ₁ . The means to do is not limited to this.
For example, as shown in FIGS. 8 to 10, two connecting members 9 are attached to the upper end portion (upper chord material) of each truss structure 12 at a predetermined interval in a direction orthogonal to the longitudinal direction. The suspended point T ₁ (T ₂ ) may be provided on the connecting member 9 in a slidable configuration. According to this method, there is an advantage that the suspended point T ₁ (T ₂ ) can be formed at a position that substantially coincides with a portion where the entire main portion 10a can be lifted with good balance.

以上に実施形態を図面に基づいて説明したが、本発明は、図示例の実施形態の限りではなく、その技術的思想を逸脱しない範囲において、当業者が通常に行う設計変更、応用のバリエーションの範囲を含むことを念のために言及する。
例えば、本実施例１、２では、２棟又は３棟の建物に空中構造体１０…を架設して実施しているが、これに限定されず、４棟以上の建物でも実施可能である（図１１参照）。
また、本実施例１、２では、平面視で、シンメトリック状にバランス良く構築して実施しているが、荷重バランスを考慮することにより、対称配置に限らず実施することができる（図１１Ｇ参照）。これに伴い、本実施例１、２では、建物棟１、１、…を同形・同大で実施しているが、これに限定されるものではなく、空中構造体を架設できる高さと幅を有する建物棟である限り、種々のバリエーションで実施可能である（図１１Ｂ、Ｇ参照）。 The embodiments have been described with reference to the drawings.
