Description

中空部材の設置構造Hollow member installation structure
　本発明は、中空部材の設置構造に関し、詳細には、中空部材の下端側における中空部材の設置構造に関する。 The present invention relates to a hollow member installation structure, and more particularly to a hollow member installation structure on the lower end side of the hollow member.
　従来、中空部材をその下端側にある下地材に固定する際、この固定は、中空部材の外側で行われている。 Conventionally, when fixing the hollow member to the base material on the lower end side, this fixing is performed outside the hollow member.
　例えば、特許文献１には、鉄骨柱（中空部材）の下端部に柱脚金物を一体に接合してなる鉄骨柱脚を、中空部材の外側において、基礎コンクリート（下地材）中に埋設されたアンカーボルトとこのアンカーボルトの上端部に螺合されるナットとを介して下地材に固定させた柱脚構造が開示されている。 For example, in Patent Document 1, a steel column post in which a column base metal piece is integrally joined to a lower end of a steel column (hollow member) is embedded in a basic concrete (base material) on the outside of the hollow member. There is disclosed a column base structure fixed to a base material via an anchor bolt and a nut screwed to an upper end portion of the anchor bolt.
　しかし、特許文献１のような柱脚構造では、柱脚金物は中空部材の外側にあり、かつこの柱脚金物の上面からナットを螺合させたアンカーボルトの上端部が上方へ突出している。このため、柱脚構造周辺では、柱脚金物を避けた作業が必要になるため、中空部材の外側における作業スペースが制限されやすい。 However, in the column base structure as in Patent Document 1, the column base metal is located outside the hollow member, and the upper end of the anchor bolt in which the nut is screwed protrudes upward from the upper surface of the column base metal. Therefore, in the vicinity of the column base structure, it is necessary to perform work avoiding the column base metal fittings, so that the work space outside the hollow member is likely to be limited.

　本発明の上記態様によれば、ベース片の少なくとも一部と固定具とが、上下方向から見た平面視において、中空部と重なる領域内にあるため、中空部材の外側における作業スペースが制限されにくくなる。 According to the above aspect of the present invention, since at least a part of the base piece and the fixture are in a region overlapping the hollow portion in a plan view seen from above and below, the working space outside the hollow member is limited.

　以下、本発明を実施するための形態を説明する。 Hereinafter, modes for carrying out the present invention will be described.
　（第１実施形態）
　＜中空部材の設置構造＞
　まず、第１実施形態に係る中空部材の設置構造（以下、設置構造という場合がある）１を、図１Ａ～図３Ｃを参照して説明する。 (First embodiment)
<Hollow member installation structure>
First, a hollow member installation structure (hereinafter, also referred to as an installation structure) 1 according to the first embodiment will be described with reference to FIGS. 1A to 3C.
　本実施形態に係る設置構造１は、建物の骨組み等に適用される構造であり、特に後述の下地材６の上に中空部材２を設置させる構造である。このため、設置構造１の上下方向Ｙは、建物の上下方向により規定される。 The installation structure 1 according to the present embodiment is a structure applied to a frame of a building or the like, and in particular, a structure in which the hollow member 2 is installed on a base material 6 described later. Therefore, the vertical direction Y of the installation structure 1 is defined by the vertical direction of the building.
　設置構造１は、図１Ａ～図１Ｃのように、中空部材２と、連結部材３と、固定具４と、を備える。中空部材２は、長さ方向が上下方向Ｙに沿うものである。中空部材２は、上下方向Ｙに沿って連続した中空部２１を有する。連結部材３は、中空部材２の下端側にある下地材６と、中空部材２と、を連結するものであり、ベース片３１と、固定片３２と、を有する。固定具４は、連結部材３を下地材６に固定するものである。固定片３２は、中空部材２を固定する部位である。ベース片３１は、固定片３２と一体で下地材６に固定される部位である。ベース片３１の少なくとも一部と固定具４とが、上下方向Ｙのうち上方から見た平面視において、中空部２１と重なる領域内にある。 The installation structure 1 includes a hollow member 2, a connecting member 3, and a fixture 4, as shown in FIGS. 1A to 1C. The hollow member 2 has a length direction along the vertical direction Y. The hollow member 2 has a hollow portion 21 that is continuous along the vertical direction Y. The connecting member 3 connects the base member 6 on the lower end side of the hollow member 2 and the hollow member 2, and has a base piece 31 and a fixing piece 32. The fixture 4 fixes the connecting member 3 to the base material 6. The fixing piece 32 is a portion for fixing the hollow member 2. The base piece 31 is a part fixed to the base material 6 integrally with the fixing piece 32. At least a part of the base piece 31 and the fixture 4 are in a region overlapping the hollow portion 21 in a plan view seen from above in the vertical direction Y.
　このような設置構造１によると、ベース片３１の少なくとも一部と固定具４とが、上下方向Ｙのうち上方から見た平面視において、中空部２１と重なる領域内にあることから、固定具４は中空部材２の外側に配置されなくなると共に、ベース片３１は中空部材２の外側に配置されにくくなる。このため、中空部材２の外側における作業スペースが制限されにくくなる。 According to the installation structure 1 as described above, at least a part of the base piece 31 and the fixture 4 are in a region overlapping the hollow portion 21 in a plan view seen from above in the up-down direction Y. 4 is not arranged outside the hollow member 2, and the base piece 31 is difficult to be arranged outside the hollow member 2. Therefore, the working space outside the hollow member 2 is less likely to be limited.
　連結部材３は、図１Ａのように、ベース片３１が固定具４により下地材６に固定された状態で、中空部材２と下地材６とを連結する部材である。連結部材３は、ベース片３１及びに固定片３２加えて、ベース片３１と一体の支持片３３を有する。連結部材３は、例えば鉄等の金属製の部材である。 The connecting member 3 is a member that connects the hollow member 2 and the base material 6 with the base piece 31 being fixed to the base material 6 by the fixture 4, as shown in FIG. 1A. The connecting member 3 has a support piece 33 integrated with the base piece 31 in addition to the base piece 31 and the fixed piece 32. The connecting member 3 is a member made of metal such as iron.
　固定片３２は、ベース片３１の外側端部から、上下方向Ｙのうち上方に凸となる部位である。固定片３２は、好ましくは平板状である。この場合、固定片３２は、中空部材２と対向する対向面を有する。この対向面は、好ましくは、中空部材２の外側面と平行である。この場合、固定片３２に中空部材２をより固定しやすくなる。このため、中空部材２を固定片３２に固定した状態で、固定片３２は中空部材２をより支えやすくなる。中空部材２を固定片３２に固定する際、固定具５が用いられる。 The fixing piece 32 is a portion that protrudes upward in the vertical direction Y from the outer end of the base piece 31. The fixing piece 32 is preferably flat. In this case, the fixed piece 32 has a facing surface that faces the hollow member 2. This facing surface is preferably parallel to the outer surface of the hollow member 2. In this case, it becomes easier to fix the hollow member 2 to the fixing piece 32. Therefore, in the state where the hollow member 2 is fixed to the fixed piece 32, the fixed piece 32 becomes easier to support the hollow member 2. When fixing the hollow member 2 to the fixing piece 32, the fixing tool 5 is used.
　また、固定片３２は、厚みを有する。固定片３２の厚み方向は、上下方向Ｙと直交する。固定片３２の厚みは、好ましくは、中空部材２の厚みよりも大きい。この場合、設置構造１の強度を向上させやすい。固定片３２の厚みは、例えば、９ｍｍである。 The fixing piece 32 also has a thickness. The thickness direction of the fixed piece 32 is orthogonal to the vertical direction Y. The thickness of the fixing piece 32 is preferably larger than the thickness of the hollow member 2. In this case, it is easy to improve the strength of the installation structure 1. The thickness of the fixed piece 32 is, for example, 9 mm.
　固定片３２は、図２Ａのように、貫通孔３５を有する。貫通孔３５は、上下方向Ｙと直交する方向に沿って、固定片３２を貫通する孔であり、固定具５の軸の直径よりも大きく、正面視で固定具５の頭部よりも小さい。このため、固定具５の軸を貫通孔３５に通した状態で、固定具５の軸を中空部材２に打ち込んで固定具５の頭部を固定片３２に接触させることにより、中空部材２は中空部２１の外側（中空部材２の外側）で固定片３２に固定される。具体的には、固定片３２は、中空部材２の外側面に固定される。本実施形態では、固定片３２は複数（図２Ａの例では、４つ）の貫通孔３５を有し、これら貫通孔３５の各々で固定具５の軸が中空部材２に打ち込まれているが（例えば、図１Ｃ参照）、中空部材２は１つの固定具５により固定片３２に固定されてもよい。 The fixing piece 32 has a through hole 35 as shown in FIG. 2A. The through hole 35 is a hole that penetrates the fixing piece 32 along a direction orthogonal to the vertical direction Y, is larger than the shaft diameter of the fixing tool 5, and is smaller than the head of the fixing tool 5 in a front view. Therefore, with the shaft of the fixture 5 inserted in the through hole 35, the shaft of the fixture 5 is driven into the hollow member 2 and the head of the fixture 5 is brought into contact with the fixing piece 32. It is fixed to the fixing piece 32 on the outside of the hollow portion 21 (outside of the hollow member 2). Specifically, the fixing piece 32 is fixed to the outer surface of the hollow member 2. In the present embodiment, the fixing piece 32 has a plurality of (four in the example of FIG. 2A) through holes 35, and the shaft of the fixture 5 is driven into the hollow member 2 in each of these through holes 35. (For example, see FIG. 1C), the hollow member 2 may be fixed to the fixing piece 32 by one fixing tool 5.
　支持片３３は、固定片３２とは異なる位置にあり、ベース片３１の外側端部から、上下方向Ｙのうち上方に凸となる部位である。このような支持片３３は、中空部材２を側方から支持する。また、支持片３３は、好ましくは、平板状である。この場合、支持片３３は、中空部材２と対向する対向面を有する。この対向面は、好ましくは、中空部材２の外側面と平行である。この場合、支持片３３は、中空部材２をより支えやすくなり、設置構造１はより安定しやすくなる。本実施形態では、支持片３３の、上下方向Ｙに沿う高さは、固定片３２の高さと同じであるが、異なっていてもよい。 The support piece 33 is located at a position different from the fixed piece 32, and is a portion that protrudes upward in the vertical direction Y from the outer end of the base piece 31. Such a support piece 33 supports the hollow member 2 from the side. The support piece 33 is preferably flat. In this case, the support piece 33 has a facing surface that faces the hollow member 2. This facing surface is preferably parallel to the outer surface of the hollow member 2. In this case, the support piece 33 is more likely to support the hollow member 2 and the installation structure 1 is more likely to be stable. In the present embodiment, the height of the support piece 33 along the vertical direction Y is the same as the height of the fixed piece 32, but may be different.
　また、支持片３３は、厚みを有する。支持片３３の厚み方向は、上下方向Ｙと直交する。支持片３３の厚みは、好ましくは、中空部材２の厚みよりも大きい。この場合、設置構造１の強度を向上させやすい。支持片３３の厚みは、例えば、９ｍｍである。 Moreover, the support piece 33 has a thickness. The thickness direction of the support piece 33 is orthogonal to the vertical direction Y. The thickness of the support piece 33 is preferably larger than the thickness of the hollow member 2. In this case, it is easy to improve the strength of the installation structure 1. The thickness of the support piece 33 is, for example, 9 mm.
　本実施形態では、図１Ａのように、支持片３３にも中空部材２を固定しているが、固定されていなくてもよい。支持片３３に中空部材２を固定しなくても、支持片３３は中空部材２を支えることができる。 In this embodiment, as shown in FIG. 1A, the hollow member 2 is also fixed to the support piece 33, but it does not have to be fixed. The support piece 33 can support the hollow member 2 without fixing the hollow member 2 to the support piece 33.
　支持片３３に中空部材２を固定する場合、支持片３３は、図２Ａのように、貫通孔３６を有する。貫通孔３６は、上下方向Ｙと直交する方向に沿って、支持片３３を貫通する孔であり、固定具５の軸の直径よりも大きく、正面視で固定具５の頭部よりも小さい。このため、固定具５の軸を貫通孔３６に通した状態で、固定具５の軸を中空部材２に打ち込んで固定具５の頭部を支持片３３に接触させることにより、中空部材２は中空部２１の外側（中空部材２の外側）で支持片３３に固定される。これにより、支持片３３が固定される場合、支持片３３は、中空部材２の外側面に固定される。本実施形態では、支持片３３は複数（図２Ａの例では、４つ）の貫通孔３６を有し、これら貫通孔３６の各々で固定具５の軸が中空部材２に打ち込まれているが（例えば、図１Ｃ参照）、支持片３３は１つの貫通孔３６を有し、１つの固定具５により支持片３３に中空部材２を固定してもよい。 When fixing the hollow member 2 to the support piece 33, the support piece 33 has a through hole 36 as shown in FIG. 2A. The through hole 36 is a hole that penetrates the support piece 33 along a direction orthogonal to the vertical direction Y, and is larger than the diameter of the shaft of the fixture 5 and smaller than the head of the fixture 5 in a front view. Therefore, with the shaft of the fixture 5 inserted into the through hole 36, the shaft of the fixture 5 is driven into the hollow member 2 and the head of the fixture 5 is brought into contact with the support piece 33. It is fixed to the support piece 33 outside the hollow portion 21 (outside the hollow member 2 ). Thereby, when the support piece 33 is fixed, the support piece 33 is fixed to the outer surface of the hollow member 2. In the present embodiment, the support piece 33 has a plurality of (four in the example of FIG. 2A) through holes 36, and the shaft of the fixture 5 is driven into the hollow member 2 in each of these through holes 36. (For example, see FIG. 1C), the support piece 33 may have one through hole 36, and the hollow member 2 may be fixed to the support piece 33 by one fixture 5.
　ベース片３１は、下地材６の設置面に設置された状態で、下地材６に固定される平板状の部位である。また、ベース片３１は、図１Ａのように、固定片３２及び支持片３３から中空部２１の外側に向かって突出していない。具体的には、ベース片３１は、上下方向Ｙのうち上方から見た平面視において、固定片３２及び支持片３３から中空部２１の外側に向かって突出していない。 The base piece 31 is a flat plate-shaped portion fixed to the base material 6 in a state of being installed on the installation surface of the base material 6. In addition, the base piece 31 does not project from the fixed piece 32 and the support piece 33 toward the outside of the hollow portion 21 as shown in FIG. 1A. Specifically, the base piece 31 does not project from the fixed piece 32 and the support piece 33 toward the outside of the hollow portion 21 in a plan view seen from above in the vertical direction Y.
　本実施形態では、ベース片３１の一部が、上下方向Ｙのうち上方から見た平面視において、中空部２１と重なる領域内にある。言い換えると、ベース片３１は中空部材２の下方で固定片３２と支持片３３とに接続し、ベース片３１の一部は中空部２１の下方にある。 In the present embodiment, a part of the base piece 31 is in a region overlapping the hollow portion 21 in a plan view seen from above in the vertical direction Y. In other words, the base piece 31 is connected to the fixed piece 32 and the support piece 33 below the hollow member 2, and a part of the base piece 31 is below the hollow portion 21.
　また、ベース片３１は、厚みを有する。ベース片３１の厚み方向は、上下方向Ｙと平行である。ベース片３１の厚みは、好ましくは、中空部材２の厚みよりも大きく、固定片３２及び支持片３３の厚みと同じである。この場合、連結部材３の強度が高くなりやすくなり、設置構造１の強度を向上させやすい。ベース片３１の厚みは、例えば、９ｍｍである。 Also, the base piece 31 has a thickness. The thickness direction of the base piece 31 is parallel to the vertical direction Y. The thickness of the base piece 31 is preferably larger than the thickness of the hollow member 2 and is the same as the thickness of the fixed piece 32 and the support piece 33. In this case, the strength of the connecting member 3 is likely to be increased, and the strength of the installation structure 1 is easily improved. The thickness of the base piece 31 is, for example, 9 mm.
　ベース片３１は、図２Ａのように、貫通孔３４を有する。貫通孔３４は、上下方向Ｙに沿ってベース片３１を貫通する孔であり、固定具４の軸４３の直径よりも大きく、上下方向Ｙのうち上方から見た平面視で固定具４の上端部よりも小さい。このため、軸４３が貫通孔３４を通った状態で、固定具４の上端部がベース片３１に接触することにより、ベース片３１は下地材６に固定される。固定具４は、図１Ｂのように、上下方向Ｙのうち上方から見た平面視において、中空部２１と重なる領域内にある。言い換えると、固定具４の上端部は、中空部２１内にある。 The base piece 31 has a through hole 34 as shown in FIG. 2A. The through hole 34 is a hole that penetrates the base piece 31 along the vertical direction Y, is larger than the diameter of the shaft 43 of the fixture 4, and is the upper end of the fixture 4 in a plan view seen from above in the vertical direction Y. Smaller than part. Therefore, the base piece 31 is fixed to the base material 6 by the upper end of the fixture 4 contacting the base piece 31 with the shaft 43 passing through the through hole 34. As shown in FIG. 1B, the fixture 4 is in a region overlapping the hollow portion 21 in a plan view seen from above in the vertical direction Y. In other words, the upper end of the fixture 4 is inside the hollow portion 21.
　本実施形態では、ベース片３１は、１つの固定具４により下地材６に固定されているが、複数の固定具４により固定されてもよい。ベース片３１が複数の固定具４により固定される場合、ベース片３１は複数の貫通孔３４を有する。 In the present embodiment, the base piece 31 is fixed to the base material 6 by one fixing tool 4, but it may be fixed by a plurality of fixing tools 4. When the base piece 31 is fixed by the plurality of fixing tools 4, the base piece 31 has a plurality of through holes 34.
　図２Ａのような連結部材３では、上下方向Ｙと直交する方向において、固定片３２と支持片３３とが対向する。このような連結部材３は、例えば、図２Ｂのような貫通孔３４、３５、３６を有するプレートを折り曲げ線３７、３７の位置で屈曲加工することで作製される。また、連結部材３は、図２Ｂのようなプレートだけでなく、図３Ａ～図３Ｃのようなプレートから作製できる。図３Ａのようなプレートからなる連結部材３では、支持片３３及び固定片３２がベース片３１に対して凸となる状態で、支持片３３と固定片３２とが隣り合う。図３Ｂのようなプレートからなる連結部材３では、支持片３３及び固定片３２がベース片３１に対して凸となる状態で、ベース片３１を介して互いに対向する一対の支持片３３、３３のうち、一方の支持片３３と固定片３２とが隣り合い、他方の支持片３３と固定片３２とが隣り合う。図３Ｃのようなプレートからなる連結部材３では、支持片３３及び固定片３２がベース片３１に対して凸となる状態で、ベース片３１を介して支持片３３と固定片３２とが対向し、さらにベース片３１を介して互いに対向する一対の支持片３３、３３のうち、一方の支持片３３と固定片３２とが隣り合うと共に、他方の支持片３３と固定片３２とが隣り合う。また、連結部材３は鋳造により作製されてもよい。 In the connecting member 3 as shown in FIG. 2A, the fixed piece 32 and the support piece 33 face each other in the direction orthogonal to the vertical direction Y. Such a connecting member 3 is produced, for example, by bending a plate having through holes 34, 35, 36 as shown in FIG. 2B at bending lines 37, 37. Further, the connecting member 3 can be manufactured not only from the plate as shown in FIG. 2B but also from the plate as shown in FIGS. 3A to 3C. 3A, the support piece 33 and the fixed piece 32 are adjacent to each other in a state where the support piece 33 and the fixed piece 32 are convex with respect to the base piece 31. In the connecting member 3 made of a plate as shown in FIG. 3B, a pair of supporting pieces 33, 33 facing each other with the base piece 31 in a state where the supporting piece 33 and the fixing piece 32 are convex with respect to the base piece 31. Among them, one support piece 33 and the fixed piece 32 are adjacent to each other, and the other support piece 33 and the fixed piece 32 are adjacent to each other. In the connecting member 3 made of a plate as shown in FIG. 3C, the support piece 33 and the fixed piece 32 are opposed to each other via the base piece 31 in a state where the support piece 33 and the fixed piece 32 are convex to the base piece 31. Of the pair of support pieces 33, 33 facing each other via the base piece 31, one support piece 33 and the fixed piece 32 are adjacent to each other, and the other support piece 33 and the fixed piece 32 are adjacent to each other. Further, the connecting member 3 may be manufactured by casting.
　設置構造１が上記いずれかの連結部材３を備え、かつ中空部材２を固定片３２だけでなく支持片３３にも固定させる場合、中空部材２は固定片３２と１以上の支持片３３とに固定される。 When the installation structure 1 includes any one of the connecting members 3 described above and the hollow member 2 is fixed not only to the fixed piece 32 but also to the support piece 33, the hollow member 2 is divided into the fixed piece 32 and one or more support pieces 33. Fixed.
　本実施形態に係る設置構造１では、連結部材３を下地材６に配置する前（例えば工場）に、中空部材２よりも軽量の連結部材３に貫通孔３４、３５、３６を形成することができるため、連結部材３の作製が容易になる。結果として、設置構造１が出来上がるまでの作業の煩雑性を軽減しやすくなり、設置構造１を作製しやすくなる。 In the installation structure 1 according to the present embodiment, the through holes 34, 35, 36 may be formed in the connecting member 3 which is lighter than the hollow member 2 before the connecting member 3 is arranged on the base material 6 (for example, in a factory). Therefore, the connection member 3 can be easily manufactured. As a result, the complexity of the work until the installation structure 1 is completed can be easily reduced, and the installation structure 1 can be easily manufactured.
　中空部材２は、外幅Ｗを有する。外幅Ｗは、中空部材２の外周縁の幅である。外幅Ｗの方向は、上下方向Ｙと直交する。外幅Ｗは、任意に設定できるが、例えば５０ｍｍ～１５０ｍｍである。この場合、中空部材２を軽量化できる。外幅Ｗは、例えば、１００ｍｍである。 The hollow member 2 has an outer width W. The outer width W is the width of the outer peripheral edge of the hollow member 2. The direction of the outer width W is orthogonal to the vertical direction Y. The outer width W can be set arbitrarily, but is, for example, 50 mm to 150 mm. In this case, the hollow member 2 can be reduced in weight. The outer width W is, for example, 100 mm.
　中空部材２は、長さを有する。中空部材の長さ方向は、上下方向Ｙに沿う。すなわち、中空部材の長さ方向は、上下方向Ｙと平行である。中空部材の長さは、外幅Ｗよりも大きい。中空部材の長さは、外幅Ｗよりも大きければ、特に限定されず、設置構造１が設けられる場所の高さ等に応じて任意に設定される。 The hollow member 2 has a length. The length direction of the hollow member is along the vertical direction Y. That is, the length direction of the hollow member is parallel to the vertical direction Y. The length of the hollow member is larger than the outer width W. The length of the hollow member is not particularly limited as long as it is larger than the outer width W, and is arbitrarily set according to the height of the place where the installation structure 1 is provided and the like.
　また、中空部材２は、厚みを有する。中空部材２の厚み方向は、上下方向Ｙと直交し、外幅Ｗの方向と平行である。中空部材２の厚みは、任意に設定できるが、例えば１．６ｍｍ～３．２ｍｍである。この場合、中空部材２を軽量化できる。中空部材２の厚みは、例えば、２．３ｍｍである。 Also, the hollow member 2 has a thickness. The thickness direction of the hollow member 2 is orthogonal to the vertical direction Y and parallel to the direction of the outer width W. The thickness of the hollow member 2 can be set arbitrarily, but is, for example, 1.6 mm to 3.2 mm. In this case, the hollow member 2 can be reduced in weight. The thickness of the hollow member 2 is 2.3 mm, for example.
　本実施形態に係る中空部材２は、設置前の状態で、貫通孔３５、３６に対応する位置に貫通孔を有していてもよく、又は有さなくてもよい。中空部材２が貫通孔を有する場合、この貫通孔は、固定具５の軸の直径よりも小さい。 The hollow member 2 according to the present embodiment may or may not have through holes at positions corresponding to the through holes 35 and 36 before installation. When the hollow member 2 has a through hole, this through hole is smaller than the diameter of the shaft of the fixture 5.
　中空部材２は、中空部２１を有する。中空部２１は長さを有する。中空部２１の長さ方向は上下方向Ｙと平行であり、中空部材２の長さと同じである。このため、１つの中空部２１が中空部材２の上端及び下端の両方に開口する。 The hollow member 2 has a hollow portion 21. The hollow portion 21 has a length. The length direction of the hollow portion 21 is parallel to the vertical direction Y and is the same as the length of the hollow member 2. Therefore, one hollow portion 21 opens at both the upper end and the lower end of the hollow member 2.
　中空部材２は、例えば鉄等の金属製の部材である。このような中空部材２として、例えば、鋼管、及びＣ型チャンネルが挙げられる。また、鋼管として、上下方向Ｙと直交する方向の断面が円又は楕円形状の鋼管、及び角形鋼管が挙げられる。特に、中空部材２は、好ましくは、角形鋼管である。角形鋼管は、上下方向Ｙと直交する方向の断面が四角形状の鋼管である。 The hollow member 2 is a member made of metal such as iron. Examples of such a hollow member 2 include a steel pipe and a C-shaped channel. Examples of the steel pipe include a steel pipe having a circular or elliptical cross section in a direction orthogonal to the vertical direction Y, and a square steel pipe. In particular, the hollow member 2 is preferably a square steel pipe. The rectangular steel pipe is a steel pipe having a rectangular cross section in a direction orthogonal to the vertical direction Y.
　本実施形態に係る設置構造１によると、ベース片３１の一部と固定具４とが、上下方向Ｙのうち上方から見た平面視において、中空部２１と重なる領域内にあることから、固定具４は中空部材２の外側に配置されなくなると共に、ベース片３１は中空部材２の外側に配置されにくくなる。このため、中空部材２の外側における作業スペースが制限されにくくなる。 According to the installation structure 1 according to the present embodiment, part of the base piece 31 and the fixture 4 are in the region overlapping the hollow portion 21 in the plan view seen from above in the up-down direction Y. The tool 4 is not placed outside the hollow member 2, and the base piece 31 is less likely to be placed outside the hollow member 2. Therefore, the working space outside the hollow member 2 is less likely to be limited.
　本実施形態において、「直交する」とは、上下方向Ｙと厳密に直交する態様だけでなく、概念上、略直交する態様も含む。また、「平行」とは、上下方向Ｙと厳密と平行な態様だけでなく、概念上、略平行な態様も含む。 In the present embodiment, “perpendicular” includes not only an aspect that is exactly orthogonal to the vertical direction Y but also an aspect that is conceptually substantially orthogonal. Further, the term “parallel” includes not only an aspect that is strictly parallel to the vertical direction Y but also an aspect that is conceptually substantially parallel.
　本実施形態に係る設置構造１では、図１Ａのように、中空部材２の下端がベース片３１に接触している。このため、下地材６の設置面に沿うベース片３１の外側において、中空部材２と下地材６との間に隙間が介在している。 In the installation structure 1 according to the present embodiment, as shown in FIG. 1A, the lower end of the hollow member 2 is in contact with the base piece 31. Therefore, there is a gap between the hollow member 2 and the base material 6 on the outside of the base piece 31 along the installation surface of the base material 6.
　固定具４は、ベース片固定用の固定具である。固定具４は、例えば、軸４３であるアンカーボルトと、ワッシャー４２と、ナット４１とを含む（図１Ａ参照）。この場合、アンカーボルトの上端部とナット４１とが螺合してベース片３１が下地材６に固定された状態で、ベース片３１とナット４１との間にワッシャー４２が介在している。このような態様において、固定具４の上端部は、ワッシャー４２と、アンカーボルトに螺合したナット４１とにより構成される。また、固定具４の他例として、ネジ、釘、及びリベットが挙げられる。この場合、固定具４の上端部は、ネジ等が有する頭部により構成される。軸４３の直径は、好ましくは、８ｍｍ～１６ｍｍである。 The fixture 4 is a fixture for fixing the base piece. The fixture 4 includes, for example, an anchor bolt that is a shaft 43, a washer 42, and a nut 41 (see FIG. 1A). In this case, the washer 42 is interposed between the base piece 31 and the nut 41 in a state where the upper end portion of the anchor bolt and the nut 41 are screwed together and the base piece 31 is fixed to the base material 6. In such a mode, the upper end portion of the fixture 4 is composed of the washer 42 and the nut 41 screwed to the anchor bolt. Other examples of the fixture 4 include screws, nails, and rivets. In this case, the upper end of the fixture 4 is formed by the head of a screw or the like. The diameter of the shaft 43 is preferably 8 mm to 16 mm.
　固定具５は、中空部材２の外側面に打ち込まれる固定具（中空部材外側面用の固定具）である。固定具５として、例えば、ネジ、釘、及びリベットが挙げられる。固定具５は、固定具４と異なり、固定具５の軸の直径は、軸４３の直径よりも小さい。固定具５の軸の長さは、任意に設定できるが、例えば、固定片３２の厚みと中空部材２の厚みとの合計よりも大きく、上下方向Ｙと直交する方向における固定片３２の外面と固定具４との間の距離よりも小さい。また、固定具４により中空部材２を支持片３３に固定させる場合、固定具４の軸の長さは、固定片３２の固定態様と同様にして設定できる。 The fixture 5 is a fixture that is driven into the outer surface of the hollow member 2 (a fixture for the outer surface of the hollow member). Examples of the fixture 5 include screws, nails, and rivets. The fixture 5 is different from the fixture 4 in that the shaft diameter of the fixture 5 is smaller than the diameter of the shaft 43. The length of the shaft of the fixture 5 can be set arbitrarily, but is, for example, greater than the total thickness of the fixed piece 32 and the thickness of the hollow member 2 and is equal to the outer surface of the fixed piece 32 in the direction orthogonal to the vertical direction Y. It is smaller than the distance to the fixture 4. When the hollow member 2 is fixed to the support piece 33 by the fixing tool 4, the shaft length of the fixing tool 4 can be set in the same manner as the fixing mode of the fixing piece 32.
　下地材６として、例えば、胴差し、床梁、土台、及び基礎コンクリートが挙げられる。下地材６が基礎コンクリートである場合、例えば、基礎コンクリート中にアンカーボルトを埋設し、このアンカーボルトの上端部が基礎コンクリートから露出する。 The base material 6 includes, for example, a gable, a floor beam, a foundation, and a foundation concrete. When the base material 6 is basic concrete, for example, an anchor bolt is embedded in the basic concrete, and the upper end portion of the anchor bolt is exposed from the basic concrete.
　本実施形態に係る設置構造１は、好ましくは柱脚構造である。この場合、中空部材２は、建物の柱となる。また、設置構造１は、縦胴縁の脚構造等にも適用できる。 The installation structure 1 according to the present embodiment is preferably a column base structure. In this case, the hollow member 2 becomes a pillar of the building. The installation structure 1 can also be applied to a vertical furring frame structure or the like.
　＜中空部材の設置方法＞
　次に、本実施形態に係る中空部材の設置方法（以下、設置方法という場合がある）を説明する。設置方法は、下地材６の上に中空部材２を設置して設置構造１を作製する方法である。このため、設置方法は、設置構造１の説明を参照できる。 <How to install the hollow member>
Next, a method of installing the hollow member according to the present embodiment (hereinafter sometimes referred to as an installation method) will be described. The installation method is a method of manufacturing the installation structure 1 by installing the hollow member 2 on the base material 6. Therefore, for the installation method, the description of the installation structure 1 can be referred to.
　本実施形態に係る設置方法は、準備工程と、配置工程と、設置工程と、を含む。 The installation method according to the present embodiment includes a preparation process, an arrangement process, and an installation process.
　準備工程は、下地材６と、中空部材２と、連結部材３と、固定具５とを用意する工程である。準備工程では、ベース片３１、及び固定片３２に、それぞれ貫通孔３４、３５を形成し、必要に応じて、支持片３３に貫通孔３６を形成する。貫通孔３４、３５、３６は、任意の孔空け加工により形成される。孔空け加工として、例えば、パンチング孔空け加工、及びドリル孔空け加工が挙げられる。 The preparation step is a step of preparing the base material 6, the hollow member 2, the connecting member 3, and the fixture 5. In the preparation step, through holes 34 and 35 are formed in the base piece 31 and the fixed piece 32, respectively, and a through hole 36 is formed in the support piece 33, if necessary. The through holes 34, 35, 36 are formed by arbitrary hole forming processing. Examples of the boring process include punching boring process and drill boring process.
　また、準備工程の際、中空部材２において、貫通孔３５、３６に対応する位置に貫通孔を形成してもよい。また、本実施形態では軸４３としてアンカーボルトが下地材６に埋設されているが、下地材６にアンカーボルトを埋設しなくてもよい。準備工程の後、配置工程、及び設置工程が行われる。 Also, in the preparation step, through holes may be formed in the hollow member 2 at positions corresponding to the through holes 35 and 36. Further, although the anchor bolt is embedded in the base material 6 as the shaft 43 in the present embodiment, the anchor bolt may not be embedded in the base material 6. After the preparation process, the placement process and the installation process are performed.
　配置工程は、連結部材３を下地材６に配置する工程である。下地材６にアンカーボルトが埋設されている場合、配置工程では、アンカーボルトの上端部を、貫通孔３４及びワッシャー４２に通してから、ナット４１と螺合させる。そして、ベース片３１にワッシャー４２を接触させると共に、ワッシャー４２にナット４１を接触させることで、下地材６にベース片３１が固定される。また、下地材６にアンカーボルトが埋設されていない場合、連結部材３が下地材６に配置された状態で、ベース片３１の上方から固定具４の軸４３を貫通孔３４に通し、その後、軸４３を下地材６に打ち込むことにより、ベース片３１を下地材６に固定してもよい。この場合、ベース片３１と固定具４の頭部との間にワッシャーを介在させてもよい。配置工程後、設置工程が行われる。 The placement step is a step of placing the connecting member 3 on the base material 6. When the anchor bolt is embedded in the base material 6, in the disposing step, the upper end portion of the anchor bolt is passed through the through hole 34 and the washer 42, and then screwed with the nut 41. The base piece 31 is fixed to the base material 6 by bringing the washer 42 into contact with the base piece 31 and the nut 41 into contact with the washer 42. When the anchor bolt is not embedded in the base material 6, the shaft 43 of the fixture 4 is passed through the through hole 34 from above the base piece 31 with the connecting member 3 arranged in the base material 6. The base piece 31 may be fixed to the base material 6 by driving the shaft 43 into the base material 6. In this case, a washer may be interposed between the base piece 31 and the head of the fixture 4. After the placing step, the setting step is performed.
　設置工程は、中空部材２を設置する工程である。設置工程中、中空部材２の下端をベース片３１に接触させ、この状態で、貫通孔３５に固定具５の軸を通してから中空部材２に打ち込むことにより、中空部材２は固定具５により固定片３２に固定される。また、本実施形態では、貫通孔３６を通った固定具５の軸を中空部材２に打ち込むことにより、支持片３３にも中空部材２を固定しているが、支持片３３に中空部材２を固定しなくてもよい。支持片３３に中空部材２を固定しなくても、支持片３３は中空部材２を支えることができる。また、中空部材２及び連結部材３が鉄等の金属製の部材である場合、溶接により連結部材３と中空部材２とを連結してもよい。 The installation process is the process of installing the hollow member 2. During the installation step, the lower end of the hollow member 2 is brought into contact with the base piece 31, and in this state, the shaft of the fixture 5 is passed through the through hole 35 and then driven into the hollow member 2, whereby the hollow member 2 is fixed by the fixture 5. It is fixed at 32. Further, in the present embodiment, the hollow member 2 is fixed to the support piece 33 by driving the shaft of the fixture 5 passing through the through hole 36 into the hollow member 2, but the hollow member 2 is fixed to the support piece 33. It does not have to be fixed. The support piece 33 can support the hollow member 2 without fixing the hollow member 2 to the support piece 33. When the hollow member 2 and the connecting member 3 are members made of metal such as iron, the connecting member 3 and the hollow member 2 may be connected by welding.
　本実施形態に係る設置方法では、下地材６に固定された連結部材３と、中空部材２とを連結することにより、中空部材２が下地材６の上に設置されて、設置構造１が作製される。 In the installation method according to the present embodiment, the hollow member 2 is installed on the base material 6 by connecting the connecting member 3 fixed to the base material 6 and the hollow member 2, and the installation structure 1 is manufactured. To be done.
　（第２実施形態）
　次に、第２実施形態に係る設置構造１を、図４Ａ～図５Ｂを参照して説明する。本実施形態では、第１実施形態と共通する構成については図面に同じ符号を付して説明を省略する。 (Second embodiment)
Next, the installation structure 1 according to the second embodiment will be described with reference to FIGS. 4A to 5B. In this embodiment, the same components as those in the first embodiment are designated by the same reference numerals in the drawings and the description thereof will be omitted.
　本実施形態に係る設置構造１は、図４Ａ～図４Ｃのように、中空部材２と、連結部材３と、固定具４と、固定具５と、を備える。 The installation structure 1 according to the present embodiment includes a hollow member 2, a connecting member 3, a fixture 4, and a fixture 5, as shown in FIGS. 4A to 4C.
　設置構造１において、図４Ａのように、中空部材２の下端が下地材６に接触した状態で、中空部材２は下地材６の上に設置されている。このような中空部材２は、図５Ａのように、貫通孔２２を有する。貫通孔２２は、上下方向Ｙと直交する方向に沿って、中空部材２を貫通する孔であり、中空部材２の下端部にある。中空部材２の下端部は、設置構造１の状態で、固定片３２及び支持片３３のうち、高い方の上端と同じ高さとなる位置と中空部材２の下端との間にある部分である。固定片３２に中空部材２を固定する際、固定具５の軸が貫通孔２２を通って中空部２１内の固定片３２に打ち込まれる。これにより、固定片３２は、中空部材２の内側面に固定される。 In the installation structure 1, as shown in FIG. 4A, the hollow member 2 is installed on the base material 6 with the lower end of the hollow member 2 in contact with the base material 6. Such a hollow member 2 has a through hole 22 as shown in FIG. 5A. The through hole 22 is a hole that penetrates the hollow member 2 along a direction orthogonal to the vertical direction Y, and is at the lower end of the hollow member 2. The lower end of the hollow member 2 is a portion between the lower end of the hollow member 2 and a position of the fixed piece 32 and the support piece 33 that have the same height as the upper end of the higher one in the state of the installation structure 1. When fixing the hollow member 2 to the fixing piece 32, the shaft of the fixing tool 5 is driven into the fixing piece 32 in the hollow portion 21 through the through hole 22. Thereby, the fixing piece 32 is fixed to the inner surface of the hollow member 2.
　本実施形態に係る中空部材２は、複数の貫通孔２２を有しているが、貫通孔２２の数は任意に設定できる。例えば、中空部材２は１つの貫通孔２２を有していてもよい。 The hollow member 2 according to the present embodiment has a plurality of through holes 22, but the number of through holes 22 can be set arbitrarily. For example, the hollow member 2 may have one through hole 22.
　連結部材３は、図４Ａのように、ベース片３１が固定具４により下地材６に固定された状態で、中空部２１内にある。このため、ベース片３１の全部が中空部２１内にあり、固定具４の上端部も中空部２１内にある。この場合、中空部材２における下端部の外側では、作業スペースがより広くなりやすい。 The connecting member 3 is inside the hollow portion 21 in a state where the base piece 31 is fixed to the base material 6 by the fixture 4, as shown in FIG. 4A. Therefore, the entire base piece 31 is in the hollow portion 21, and the upper end portion of the fixture 4 is also in the hollow portion 21. In this case, the work space tends to be wider outside the lower end of the hollow member 2.
　固定片３２は、中空部材２と対向する対向面を有する。この対向面は、好ましくは、中空部材２の内側面と平行である。この場合、固定片３２に中空部材２をより固定しやすくなる。このため、固定片３２に中空部材２を固定した状態で、固定片３２は中空部材２をより支えやすくなる。 The fixing piece 32 has a facing surface facing the hollow member 2. This facing surface is preferably parallel to the inner surface of the hollow member 2. In this case, it becomes easier to fix the hollow member 2 to the fixing piece 32. Therefore, in the state where the hollow member 2 is fixed to the fixed piece 32, the fixed piece 32 becomes easier to support the hollow member 2.
　固定片３２は、貫通孔２２に対応する位置に貫通孔を有していないが（図５Ｂ参照）、貫通孔を有してもよい。固定片３２が貫通孔を有する場合、貫通孔は固定具５の軸の直径よりも小さい。 The fixing piece 32 does not have a through hole at a position corresponding to the through hole 22 (see FIG. 5B), but may have a through hole. When the fixing piece 32 has a through hole, the through hole is smaller than the diameter of the shaft of the fixture 5.
　支持片３３は、中空部材２と対向する対向面を有する。この対向面は、好ましくは、中空部材２の内側面と平行である。この場合、支持片３３は、中空部材２をより支えやすくなり、設置構造１はより安定しやすくなる。本実施形態では、支持片３３の、上下方向Ｙに沿う高さは、固定片３２の高さと同じであるが、異なっていてもよい。 The support piece 33 has a facing surface that faces the hollow member 2. This facing surface is preferably parallel to the inner surface of the hollow member 2. In this case, the support piece 33 is more likely to support the hollow member 2 and the installation structure 1 is more likely to be stable. In the present embodiment, the height of the support piece 33 along the vertical direction Y is the same as the height of the fixed piece 32, but may be different.
　支持片３３は、貫通孔２２に対応する位置に貫通孔を有していないが（図５Ｂ参照）、貫通孔を有してもよい。支持片３３が貫通孔を有する場合、貫通孔は固定具５の軸の直径よりも小さい。また、本実施形態では、支持片３３にも中空部材２を固定しているが（図４Ａ参照）、支持片３３に中空部材２を固定しなくてもよい。支持片３３に中空部材２を固定する場合、固定具５の軸は貫通孔２２を通って支持片３３に打ち込まれる。これにより、支持片３３は、中空部材２の内側面に固定される。 The support piece 33 does not have a through hole at a position corresponding to the through hole 22 (see FIG. 5B), but may have a through hole. When the support piece 33 has a through hole, the through hole is smaller than the diameter of the shaft of the fixture 5. Further, in the present embodiment, the hollow member 2 is also fixed to the support piece 33 (see FIG. 4A), but the hollow member 2 may not be fixed to the support piece 33. When fixing the hollow member 2 to the support piece 33, the shaft of the fixture 5 is driven into the support piece 33 through the through hole 22. As a result, the support piece 33 is fixed to the inner surface of the hollow member 2.
　本実施形態に係る中空部材２を下地材６の上に設置するにあたって、準備工程では、中空部材２の下端部に貫通孔２２を形成する。この貫通孔２２は、設置工程の際に固定片３２と対向させる部分に形成され、また必要に応じて、支持片３３と対向させる部分にも形成される。貫通孔２２は、任意の孔空け加工により形成される。孔空け加工として、例えば、パンチング孔空け加工、及びドリル孔空け加工が挙げられる。 In installing the hollow member 2 according to the present embodiment on the base material 6, in the preparation step, the through hole 22 is formed in the lower end portion of the hollow member 2. The through hole 22 is formed in a portion facing the fixing piece 32 during the installation process, and is also formed in a portion facing the supporting piece 33 as necessary. The through hole 22 is formed by an arbitrary boring process. Examples of the boring process include punching boring process and drill boring process.
　設置工程では、連結部材３が中空部２１内にある状態で、中空部材２の下端を下地材６に接触させる。そして、貫通孔２２に固定具５の軸を通してから固定片３２に打ち込むことにより、中空部材２は固定具５により固定片３２に固定される。また、貫通孔２２に固定具５の軸を通してから支持片３３に打ち込むことにより、支持片３３にも中空部材２は固定具５により固定される。 In the installation step, the lower end of the hollow member 2 is brought into contact with the base material 6 while the connecting member 3 is inside the hollow portion 21. Then, the hollow member 2 is fixed to the fixing piece 32 by the fixing tool 5 by driving the shaft of the fixing tool 5 through the through hole 22 and then driving it into the fixing piece 32. Further, the hollow member 2 is fixed to the support piece 33 by the fixture 5 by driving the shaft of the fixture 5 through the through hole 22 and then driving it into the support piece 33.

　＜中空部材の設置構造＞
　次に、第３実施形態に係る設置構造１を、図６及び図７を参照して説明する。第３実施形態では、第１及び第２実施形態と共通する構成については図面に同じ符号を付して説明を省略する。 (Third Embodiment)
<Hollow member installation structure>
Next, the installation structure 1 according to the third embodiment will be described with reference to FIGS. 6 and 7. In the third embodiment, the same components as those in the first and second embodiments are designated by the same reference numerals in the drawings, and the description thereof will be omitted.
　本実施形態に係る設置構造１は、図６のように、中空部材２と、連結部材３と、支持部材７と、固定具４と、固定具８と、を備える。固定具４は第１固定具であり、固定具８は第２固定具である。このような設置構造１では、中空部材２の下端が後述のベース片３１、７１に接触した状態で、中空部材２は下地材６の上に設置されている（図６参照）。 The installation structure 1 according to the present embodiment includes a hollow member 2, a connecting member 3, a support member 7, a fixture 4, and a fixture 8, as shown in FIG. 6. The fixture 4 is a first fixture and the fixture 8 is a second fixture. In such an installation structure 1, the hollow member 2 is installed on the base material 6 in a state where the lower end of the hollow member 2 is in contact with base pieces 31 and 71 described later (see FIG. 6 ).
　連結部材３は、図６のように、ベース片３１と、固定片３２と、を有する。ベース片３１は貫通孔３４を有し、固定片３２は貫通孔３５を有する（図７参照）。また、連結部材３は支持片（例えば、図２Ａの支持片３３）を有さない。このような連結部材３として、例えば、Ｌ型アングルが挙げられる。 The connecting member 3 has a base piece 31 and a fixing piece 32 as shown in FIG. The base piece 31 has a through hole 34, and the fixed piece 32 has a through hole 35 (see FIG. 7). Further, the connecting member 3 does not have a supporting piece (for example, the supporting piece 33 in FIG. 2A). An example of such a connecting member 3 is an L-shaped angle.
　また、本実施形態では、ベース片３１の一部が、上下方向Ｙのうち上方から見た平面視において、中空部２１と重なる領域内にある。言い換えると、ベース片３１は中空部材２の下方にあり、ベース片３１の一部は中空部２１の下方にある。 Further, in the present embodiment, a part of the base piece 31 is in a region overlapping the hollow portion 21 in a plan view seen from above in the vertical direction Y. In other words, the base piece 31 is below the hollow member 2, and a part of the base piece 31 is below the hollow portion 21.
　支持部材７は、図６のように、第２固定具８により下地材６に固定された状態で、中空部材２を支持する部材である。支持部材７は、ベース片７１と、ベース片７１と一体の支持片７２を有する。支持部材７は、例えば鉄等の金属製の部材である。 The support member 7 is a member that supports the hollow member 2 in a state of being fixed to the base material 6 by the second fixing tool 8 as shown in FIG. The support member 7 has a base piece 71 and a support piece 72 integrated with the base piece 71. The support member 7 is a member made of metal such as iron.
　支持片７２は、ベース片７１の外側端部から、上下方向Ｙのうち上方に凸となる部位である。このような支持片７２は、中空部材２を側方から支持する。また、支持片７２は、好ましくは、平板状である。この場合、支持片７２は、中空部材２と対向する対向面を有する。この対向面は、好ましくは、中空部材２の外側面と平行である。この場合、支持片７２は、中空部材２をより支えやすくなり、設置構造１はより安定しやすくなる。本実施形態では、支持片７２の、上下方向Ｙに沿う高さは、固定片３２の高さと同じであるが、異なっていてもよい。例えば、支持片７２は、固定片３２よりも高くてもよい。 The support piece 72 is a portion that protrudes upward in the vertical direction Y from the outer end of the base piece 71. Such a supporting piece 72 supports the hollow member 2 from the side. The support piece 72 is preferably flat. In this case, the support piece 72 has a facing surface that faces the hollow member 2. This facing surface is preferably parallel to the outer surface of the hollow member 2. In this case, the support piece 72 is more likely to support the hollow member 2 and the installation structure 1 is more likely to be stable. In the present embodiment, the height of the support piece 72 along the vertical direction Y is the same as the height of the fixed piece 32, but may be different. For example, the support piece 72 may be higher than the fixed piece 32.
　また、支持片７２は、厚みを有する。支持片７２の厚み方向は、上下方向Ｙと直交する。支持片７２の厚みは、好ましくは、中空部材２の厚みよりも大きい。この場合、設置構造１の強度を向上させやすい。支持片７２の厚みは、例えば、９ｍｍである。 Also, the support piece 72 has a thickness. The thickness direction of the support piece 72 is orthogonal to the vertical direction Y. The thickness of the support piece 72 is preferably larger than the thickness of the hollow member 2. In this case, it is easy to improve the strength of the installation structure 1. The thickness of the support piece 72 is, for example, 9 mm.
　本実施形態では、図６のように、支持片７２にも中空部材２を固定しているが、支持片７２に固定しなくてもよい。支持片７２に中空部材２を固定しなくても、支持片７２は中空部材２を支えることができる。 In the present embodiment, as shown in FIG. 6, the hollow member 2 is also fixed to the support piece 72, but it is not necessary to fix it to the support piece 72. The support piece 72 can support the hollow member 2 without fixing the hollow member 2 to the support piece 72.
　支持片７２に中空部材２を固定する場合、支持片７２は、図７のように、貫通孔７５を有する。貫通孔７５は、上下方向Ｙと直交する方向に沿って、支持片７２を貫通する孔であり、固定具５の軸の直径よりも大きく、正面視で固定具５の頭部よりも小さい。このため、固定具５の軸を貫通孔７５に通した状態で、固定具５の軸を中空部材２に打ち込んで固定具５の頭部を支持片７２に接触させることにより、中空部材２は中空部２１の外側（中空部材２の外側）で支持片７２に固定される。すなわち、支持片７２は、中空部材２の内側面に固定される。本実施形態では、支持片７２は複数（図７の例では、４つ）の貫通孔７５を有し、これら貫通孔７５の各々を通して固定具５の軸が中空部材２に打ち込まれているが（例えば、図６参照）、支持片７２は１つの貫通孔３６を有し、１つの固定具５により中空部材２を支持片７２に固定してもよい。 When fixing the hollow member 2 to the support piece 72, the support piece 72 has a through hole 75 as shown in FIG. 7. The through hole 75 is a hole that penetrates the support piece 72 along a direction orthogonal to the vertical direction Y, and is larger than the diameter of the shaft of the fixture 5 and smaller than the head of the fixture 5 in a front view. Therefore, with the shaft of the fixture 5 inserted in the through hole 75, the shaft of the fixture 5 is driven into the hollow member 2 so that the head of the fixture 5 contacts the support piece 72, whereby the hollow member 2 is It is fixed to the support piece 72 outside the hollow portion 21 (outside the hollow member 2 ). That is, the support piece 72 is fixed to the inner surface of the hollow member 2. In the present embodiment, the support piece 72 has a plurality of (four in the example of FIG. 7) through holes 75, and the shaft of the fixture 5 is driven into the hollow member 2 through each of these through holes 75. (For example, see FIG. 6) The supporting piece 72 may have one through hole 36, and the hollow member 2 may be fixed to the supporting piece 72 by one fixing tool 5.
　ベース片７１は、上下方向Ｙと直交する方向に沿って、下地材６の設置面に配置される平板状の部位である。また、ベース片７１は、図６のように、支持片７２から中空部２１の外側に向かって突出していない。具体的には、ベース片７１は、上下方向Ｙのうち上方から見た平面視において、支持片７２から中空部２１の外側に向かって突出していない。 The base piece 71 is a flat plate-shaped portion arranged on the installation surface of the base material 6 along the direction orthogonal to the vertical direction Y. Further, the base piece 71 does not protrude from the support piece 72 toward the outside of the hollow portion 21 as shown in FIG. Specifically, the base piece 71 does not project from the support piece 72 toward the outside of the hollow portion 21 in a plan view seen from above in the vertical direction Y.
　本実施形態では、ベース片７１の一部が、上下方向Ｙのうち上方から見た平面視において、中空部２１と重なる領域内にある。言い換えると、ベース片７１は中空部材２の下方にあり、ベース片７１の一部は中空部２１の下方にある。 In the present embodiment, a part of the base piece 71 is in a region that overlaps the hollow portion 21 in a plan view seen from above in the vertical direction Y. In other words, the base piece 71 is below the hollow member 2, and a part of the base piece 71 is below the hollow portion 21.
　また、ベース片７１は、厚みを有する。ベース片７１の厚み方向は、上下方向Ｙと平行である。ベース片７１の厚みは、好ましくは、中空部材２の厚みよりも大きく、支持片７２の厚みと同じである。この場合、支持部材７の強度は高くなりやすくなり、設置構造１の強度を向上させやすい。ベース片７１の厚みは、例えば、９ｍｍである。 Also, the base piece 71 has a thickness. The thickness direction of the base piece 71 is parallel to the vertical direction Y. The thickness of the base piece 71 is preferably larger than the thickness of the hollow member 2 and the same as the thickness of the support piece 72. In this case, the strength of the support member 7 is likely to be high, and the strength of the installation structure 1 is easily improved. The thickness of the base piece 71 is, for example, 9 mm.
　ベース片７１は、図７のように、貫通孔７４を有する。貫通孔７４は、上下方向Ｙに沿ってベース片７１を貫通する孔であり、第２固定具８の軸８３の直径よりも大きく、上下方向Ｙのうち上方から見た平面視で第２固定具８の上端部よりも小さい。このため、軸８３が貫通孔７４を通った状態で、第２固定具８の上端部がベース片７１に接触することにより、ベース片７１は下地材６に固定される。第２固定具８は、図６のように、上下方向Ｙのうち上方から見た平面視において、中空部２１と重なる領域内にある。言い換えると、第２固定具８の上端部は、中空部２１内にある。 The base piece 71 has a through hole 74 as shown in FIG. The through hole 74 is a hole that penetrates the base piece 71 along the up-down direction Y, is larger than the diameter of the shaft 83 of the second fixture 8, and is second fixed in a plan view when viewed from above in the up-down direction Y. It is smaller than the upper end of the tool 8. Therefore, with the shaft 83 passing through the through hole 74, the upper end of the second fixture 8 contacts the base piece 71, so that the base piece 71 is fixed to the base material 6. As shown in FIG. 6, the second fixture 8 is in a region overlapping the hollow portion 21 in the plan view seen from above in the vertical direction Y. In other words, the upper end of the second fixture 8 is inside the hollow portion 21.
　本実施形態では、ベース片７１は、１つの第２固定具８により下地材６に固定されているが、複数の第２固定具８により固定されてもよい。ベース片７１が複数の第２固定具８により固定される場合、ベース片７１は複数の貫通孔７４を有する。 In the present embodiment, the base piece 71 is fixed to the base material 6 by one second fixing tool 8, but it may be fixed by a plurality of second fixing tools 8. When the base piece 71 is fixed by the plurality of second fixtures 8, the base piece 71 has a plurality of through holes 74.
　上記のようなベース片７１と支持片７２とを有する支持部材７として、例えば、Ｌ型アングルが挙げられる。 An example of the supporting member 7 having the base piece 71 and the supporting piece 72 as described above is an L-shaped angle.
　本実施形態に係る設置構造１によると、ベース片３１の一部と、ベース片７１の一部と、第１固定具４と、第２固定具８とが、上下方向Ｙのうち上方から見た平面視において、中空部２１と重なる領域内にあることから、第１及び第２固定具４、８は中空部材２の外側に配置されなくなると共に、ベース片３１、７１は中空部材２の外側に配置されにくくなる。このため、中空部材２の下端部の外側における作業スペースが制限されにくくなる。 According to the installation structure 1 of the present embodiment, a part of the base piece 31, a part of the base piece 71, the first fixing tool 4, and the second fixing tool 8 are viewed from above in the vertical direction Y. In the plan view, the first and second fixtures 4 and 8 are not arranged outside the hollow member 2 and are located outside the hollow member 2 because the first and second fixing members 4 and 8 are located outside the hollow member 2 in the area overlapping the hollow portion 21. It is difficult to place it in. Therefore, the working space outside the lower end of the hollow member 2 is less likely to be limited.
　中空部材２の下端部は、設置構造１の状態で、固定片３２及び支持片７２のうち、高い方の上端と同じ高さとなる位置と中空部材２の下端との間にある部分である。 The lower end of the hollow member 2 is a portion between the lower end of the hollow member 2 and the position of the fixed piece 32 and the support piece 72 that is at the same height as the upper end of the higher one in the state of the installation structure 1.
　第２固定具８は、ベース片固定用の固定具である。第２固定具８は、例えば、軸８３であるアンカーボルトと、ワッシャー８２と、ナット８１とを含む（図６参照）。この場合、アンカーボルトの上端部とナット８１とが螺合してベース片７１が下地材６に固定された状態で、ベース片７１とナット８１との間にワッシャー８２が介在している。このような態様において、第２固定具８の上端部は、ワッシャー８２と、アンカーボルトに螺合したナット８１とにより構成される。また、第２固定具８の他例として、ネジ、釘、及びリベットが挙げられる。この場合、第２固定具８の上端部は、ネジ等が有する頭部により構成される。軸８３の直径は、好ましくは、８ｍｍ～１６ｍｍである。第２固定具８は、第１固定具４と同じであってもよい。 The second fixture 8 is a fixture for fixing the base piece. The second fixture 8 includes, for example, an anchor bolt that is a shaft 83, a washer 82, and a nut 81 (see FIG. 6 ). In this case, a washer 82 is interposed between the base piece 71 and the nut 81 in a state where the upper end portion of the anchor bolt and the nut 81 are screwed together and the base piece 71 is fixed to the base material 6. In such a mode, the upper end portion of the second fixture 8 is composed of the washer 82 and the nut 81 screwed into the anchor bolt. Other examples of the second fixture 8 include screws, nails, and rivets. In this case, the upper end portion of the second fixing tool 8 is composed of a head portion such as a screw. The diameter of the shaft 83 is preferably 8 mm to 16 mm. The second fixture 8 may be the same as the first fixture 4.
　＜中空部材の設置方法＞
　次に、本実施形態に係る設置方法を説明する。設置方法は、下地材６の上に中空部材２を設置して設置構造１を作製する方法である。このため、設置方法は、設置構造１の説明を参照できる。 <How to install the hollow member>
Next, the installation method according to this embodiment will be described. The installation method is a method of preparing the installation structure 1 by installing the hollow member 2 on the base material 6. Therefore, for the installation method, the description of the installation structure 1 can be referred to.
　本実施形態に係る設置方法は、準備工程と、配置工程と、設置工程と、を含む。 The installation method according to the present embodiment includes a preparation process, an arrangement process, and an installation process.
　準備工程は、下地材６と、中空部材２と、連結部材３と、支持部材７と、固定具５と、を用意する工程である。準備工程では、ベース片３１、固定片３２、ベース片７１に、それぞれ貫通孔３４、３５、７４を形成し、必要に応じて、支持片７２に貫通孔７５を形成する。貫通孔３４、３５、７４、７５は、任意の孔空け加工により形成される。孔空け加工として、例えば、パンチング孔空け加工、及びドリル孔空け加工が挙げられる。 The preparation step is a step of preparing the base material 6, the hollow member 2, the connecting member 3, the support member 7, and the fixture 5. In the preparation step, the through holes 34, 35, 74 are formed in the base piece 31, the fixed piece 32, and the base piece 71, respectively, and the through holes 75 are formed in the support piece 72 as needed. The through holes 34, 35, 74, 75 are formed by arbitrary hole forming processing. Examples of the boring process include punching boring process and drill boring process.
　また、準備工程の際、中空部材２において、貫通孔３５、７５に対応する位置に貫通孔を形成してもよい。また、本実施形態では軸４３、８３としてアンカーボルトが下地材６に埋設されているが、下地材６にアンカーボルトを埋設しなくてもよい。準備工程の後、配置工程、及び設置工程が行われる。 Further, in the preparation step, through holes may be formed in the hollow member 2 at positions corresponding to the through holes 35 and 75. Further, in the present embodiment, the anchor bolts are embedded in the base material 6 as the shafts 43 and 83, but the anchor bolts may not be embedded in the base material 6. After the preparation process, the placement process and the installation process are performed.
　配置工程は、連結部材３及び支持部材７を下地材６に配置する工程である。下地材６に軸４３であるアンカーボルトが埋設されている場合、配置工程では、アンカーボルトの上端部を、貫通孔３４及びワッシャー４２に通してから、ナット４１と螺合させる。そして、ベース片３１にワッシャー４２を接触させると共に、ワッシャー４２にナット４１を接触させることで、下地材６にベース片３１が固定される。また、下地材６に軸８３であるアンカーボルトが埋設されている場合、アンカーボルトの上端部を、貫通孔７４及びワッシャー８２に通してから、ナット８１と螺合させる。そして、ベース片７１にワッシャー８２を接触させると共に、ワッシャー８２にナット８１を接触させることで、下地材６にベース片７１が固定される。 The placement step is a step of placing the connecting member 3 and the supporting member 7 on the base material 6. When the anchor bolt that is the shaft 43 is embedded in the base material 6, in the disposing step, the upper end portion of the anchor bolt is passed through the through hole 34 and the washer 42, and then screwed with the nut 41. The base piece 31 is fixed to the base material 6 by bringing the washer 42 into contact with the base piece 31 and the nut 41 into contact with the washer 42. When the anchor bolt, which is the shaft 83, is embedded in the base material 6, the upper end of the anchor bolt is passed through the through hole 74 and the washer 82, and then screwed with the nut 81. The base piece 71 is fixed to the base material 6 by bringing the washer 82 into contact with the base piece 71 and the nut 81 into contact with the washer 82.
　下地材６にアンカーボルトが埋設されていない場合、連結部材３及び支持部材７が下地材６に配置された状態で、ベース片３１の上方から第１固定具４の軸４３を貫通孔３４に通し、かつ、ベース片７１の上方から第２固定具８の軸８３を貫通孔７４に通してもよい。その後、第１及び第２固定具４、８を下地材６に打ち込むことにより、ベース片３１、７１を下地材６に固定できる。この場合、ベース片３１と第１固定具４の頭部との間、及びにベース片７１と第２固定具８の頭部との間にワッシャーを介在させてもよい。配置工程後、設置工程が行われる。 When the anchor bolt is not embedded in the base material 6, the shaft 43 of the first fixture 4 is inserted into the through hole 34 from above the base piece 31 with the connecting member 3 and the support member 7 arranged in the base material 6. The shaft 83 of the second fixture 8 may be passed through the through hole 74 from above the base piece 71. After that, the base pieces 31 and 71 can be fixed to the base material 6 by driving the first and second fixtures 4 and 8 into the base material 6. In this case, washers may be interposed between the base piece 31 and the head of the first fixing tool 4, and between the base piece 71 and the head of the second fixing tool 8. After the placing step, the setting step is performed.
　設置工程は、中空部材２を設置する工程である。設置工程中、中空部材２の下端をベース片３１、７１に接触させ、この状態で、貫通孔３５に固定具５の軸を通してから中空部材２に打ち込むことにより、中空部材２は固定具５により固定片３２に固定される。また、本実施形態では、貫通孔７５を通った固定具５の軸を中空部材２に打ち込むことにより、支持片７２にも中空部材２を固定しているが、支持片７２に中空部材２を固定しなくてもよい。支持片７２に中空部材２を固定しなくても、支持片７２は中空部材２を支えることができる。また、中空部材２、連結部材３、及び支持部材７が鉄等の金属製の部材である場合、溶接により、中空部材２と連結部材３とを連結し、中空部材２と支持部材７とを連結してもよい。 The installation process is the process of installing the hollow member 2. During the installation process, the lower end of the hollow member 2 is brought into contact with the base pieces 31 and 71, and in this state, the shaft of the fixture 5 is passed through the through hole 35 and then driven into the hollow member 2, whereby the hollow member 2 is fixed by the fixture 5. It is fixed to the fixing piece 32. Further, in the present embodiment, the hollow member 2 is fixed to the support piece 72 by driving the shaft of the fixture 5 that has passed through the through hole 75 into the hollow member 2, but the hollow member 2 is fixed to the support piece 72. It does not have to be fixed. The support piece 72 can support the hollow member 2 without fixing the hollow member 2 to the support piece 72. When the hollow member 2, the connecting member 3, and the supporting member 7 are members made of metal such as iron, the hollow member 2 and the connecting member 3 are connected by welding to connect the hollow member 2 and the supporting member 7 to each other. You may connect.
　本実施形態に係る設置方法では、下地材６に固定された連結部材３を中空部材２に連結すると共に、下地材６に固定された支持部材７で中空部材２を支えることにより、中空部材２が下地材６の上に設置されて、設置構造１が作製される。 In the installation method according to this embodiment, the hollow member 2 is supported by connecting the connecting member 3 fixed to the base material 6 to the hollow member 2 and supporting the hollow member 2 by the support member 7 fixed to the base material 6. Are installed on the base material 6 to produce the installation structure 1.
　（第４実施形態）
　次に、第４実施形態に係る設置構造１を、図８、及び図９を参照して説明する。本実施形態では、第２及び第３実施形態と共通する構成については図面に同じ符号を付して説明を省略する。 (Fourth Embodiment)
Next, the installation structure 1 according to the fourth embodiment will be described with reference to FIGS. 8 and 9. In this embodiment, the same reference numerals are given to the drawings for the configurations common to the second and third embodiments, and the description will be omitted.
　本実施解体に係る設置構造１は、図８のように、中空部材２と、連結部材３と、支持部材７と、第１固定具４と、第２固定具８と、固定具５と、を備える。 As shown in FIG. 8, the installation structure 1 according to the dismantling of the present embodiment includes a hollow member 2, a connecting member 3, a supporting member 7, a first fixing tool 4, a second fixing tool 8, and a fixing tool 5. Equipped with.
　設置構造１において、図８のように、中空部材２の下端が下地材６に接触した状態で、中空部材２は下地材６の上に設置されている。このような中空部材２は、貫通孔２２を有する。固定片３２に中空部材２を固定する際、固定具５の軸が貫通孔２２を通って中空部２１内の固定片３２に打ち込まれる。これにより、固定片３２は、中空部材２の内側面に固定される。また、固定具５が打ち込まれる前の固定片３２は、図７のような貫通孔３５を有さなくてもよい（図９参照）。すなわち、固定具５が打ち込まれていない状態で、固定片３２のうち、中空部材２と対向する対向面は、一平面であってもよい。 In the installation structure 1, as shown in FIG. 8, the hollow member 2 is installed on the base material 6 with the lower end of the hollow member 2 in contact with the base material 6. Such a hollow member 2 has a through hole 22. When fixing the hollow member 2 to the fixing piece 32, the shaft of the fixing tool 5 is driven into the fixing piece 32 in the hollow portion 21 through the through hole 22. Thereby, the fixing piece 32 is fixed to the inner surface of the hollow member 2. Further, the fixing piece 32 before the fixing tool 5 is driven may not have the through hole 35 as shown in FIG. 7 (see FIG. 9). That is, the facing surface of the fixing piece 32 that faces the hollow member 2 in the state where the fixing tool 5 is not driven may be a single plane.
　本実施形態に係る中空部材２は、複数の貫通孔２２を有しているが、貫通孔２２の数は任意に設定できる。例えば、中空部材２は１つの貫通孔２２を有していてもよい。 The hollow member 2 according to the present embodiment has a plurality of through holes 22, but the number of through holes 22 can be set arbitrarily. For example, the hollow member 2 may have one through hole 22.
　連結部材３は、図８のように、ベース片３１が第１固定具４により下地材６に固定された状態で、中空部２１内にある。このため、ベース片３１の全部が中空部２１内にあり、第１固定具４の上端部も中空部２１内にある。この場合、中空部材２における下端部の外側では、作業スペースがより広くなりやすい。 As shown in FIG. 8, the connecting member 3 is in the hollow portion 21 in a state where the base piece 31 is fixed to the base material 6 by the first fixing tool 4. Therefore, the entire base piece 31 is inside the hollow portion 21, and the upper end portion of the first fixture 4 is also inside the hollow portion 21. In this case, the work space tends to be wider outside the lower end of the hollow member 2.
　支持部材７は、ベース片７１が第２固定具８により下地材６に固定された状態で、中空部２１内にある。このため、ベース片７１の全部が中空部２１内にあり、第２固定具８の上端部も中空部２１内にある。この場合、中空部材２における下端部の外側では、作業スペースがより広くなりやすい。 The support member 7 is in the hollow portion 21 in a state where the base piece 71 is fixed to the base material 6 by the second fixing tool 8. Therefore, the entire base piece 71 is inside the hollow portion 21, and the upper end portion of the second fixing tool 8 is also inside the hollow portion 21. In this case, the work space tends to be wider outside the lower end of the hollow member 2.
　支持片７２は、中空部材２と対向する対向面を有する。この対向面は、好ましくは、中空部材２の内面と平行である。この場合、支持片７２は、中空部材２をより支えやすくなり、設置構造１はより安定しやすくなる。本実施形態では、支持片７２の、上下方向Ｙに沿う高さは、固定片３２の高さと同じであるが、異なっていてもよい。 The support piece 72 has a facing surface that faces the hollow member 2. This facing surface is preferably parallel to the inner surface of the hollow member 2. In this case, the support piece 72 is more likely to support the hollow member 2 and the installation structure 1 is more likely to be stable. In the present embodiment, the height of the support piece 72 along the vertical direction Y is the same as the height of the fixed piece 32, but may be different.
　支持片７２は、貫通孔２２に対応する位置に貫通孔を有してもよく、有さなくてもよい。支持片７２が貫通孔を有する場合、貫通孔は固定具５の軸の直径よりも小さい。また、本実施形態では、支持片７２にも中空部材２を固定しているが（図８参照）、支持片７２に中空部材２を固定しなくてもよい。支持片７２に中空部材２を固定する場合、固定具５の軸は貫通孔２２を通って支持片７２に打ち込まれる。これにより、支持片７２は、中空部材２の内側面に固定される。また、固定具５が打ち込まれる前の支持片７２は、図７のような貫通孔７５を有さなくてもよい（図９参照）。すなわち、固定具５が打ち込まれていない状態で、支持片７２のうち、中空部材２と対向する対向面は、一平面であってもよい。 The support piece 72 may or may not have a through hole at a position corresponding to the through hole 22. When the support piece 72 has a through hole, the through hole is smaller than the diameter of the shaft of the fixture 5. Further, in the present embodiment, the hollow member 2 is also fixed to the support piece 72 (see FIG. 8), but the hollow member 2 may not be fixed to the support piece 72. When fixing the hollow member 2 to the support piece 72, the shaft of the fixture 5 is driven into the support piece 72 through the through hole 22. As a result, the support piece 72 is fixed to the inner surface of the hollow member 2. Further, the support piece 72 before the fixing tool 5 is driven may not have the through hole 75 as shown in FIG. 7 (see FIG. 9). That is, the facing surface of the support piece 72 that faces the hollow member 2 may be a flat surface in the state where the fixture 5 is not driven.
　本実施形態に係る中空部材２を下地材６の上に設置するにあたって、準備工程では、中空部材２の下端部に貫通孔２２を形成する。この貫通孔２２は、設置工程の際に固定片３２と対向させる部分に形成され、また必要に応じて、支持片７２と対向させる部分にも形成される。貫通孔２２は、任意の孔空け加工により形成される。孔空け加工として、例えば、パンチング孔空け加工、及びドリル孔空け加工が挙げられる。 In installing the hollow member 2 according to the present embodiment on the base material 6, in the preparation step, the through hole 22 is formed in the lower end portion of the hollow member 2. The through hole 22 is formed in a portion facing the fixing piece 32 during the installation process, and is also formed in a portion facing the supporting piece 72 as necessary. The through hole 22 is formed by an arbitrary boring process. Examples of the boring process include punching boring process and drill boring process.
