Description
本発明は、建築構造物を構成し、貫通孔を有する梁を補強するための梁補強金具および梁補強構造に関するものである。 TECHNICAL FIELD The present invention relates to a beam reinforcing metal fitting and a beam reinforcing structure for reinforcing a beam having through-holes in a building structure.
従来、建築構造物の梁には配管や配線を通すために貫通孔が形成されることがある。この場合、貫通孔により、梁の曲げ耐力が低下する。この梁の曲げ耐力低下を防ぐため梁に梁補強金具を接合し、梁の補強を行っている。 Conventionally, through-holes are sometimes formed in beams of building structures for the passage of pipes and wiring. In this case, the through holes reduce the bending resistance of the beam. In order to prevent this deterioration of the bending strength of the beams, beam reinforcing metal fittings are attached to the beams to reinforce the beams.
このような梁補強金具としては、例えば、リング状の部材であって、梁に形成された貫通孔に接合する梁補強金具がある(例えば特許文献1)。 As such a beam reinforcing metal fitting, for example, there is a beam reinforcing metal fitting which is a ring-shaped member and is joined to a through hole formed in a beam (for example, Patent Document 1).
しかし、従来の梁補強金具を用いる場合、リング状の本体部の挿入側の端部の外径と貫通孔の内径との差がほとんどないため、本体部の軸方向と貫通孔の軸方向とを一致させた状態で本体部の貫通孔への挿入を開始する必要がある。挿入開始時に貫通孔の軸方向に対して本体部の軸方向が傾いていると、途中で本体部が貫通孔に引っ掛かりスムーズに作業ができない。 However, when using a conventional beam reinforcing metal fitting, there is almost no difference between the outer diameter of the insertion side end of the ring-shaped main body and the inner diameter of the through hole. It is necessary to start inserting into the through-hole of the main body with the If the axial direction of the main body is tilted with respect to the axial direction of the through-hole at the start of insertion, the main body will get caught in the through-hole in the middle of the insertion, preventing smooth operation.
本発明は、このような問題に鑑みてなされたもので、梁の貫通孔に挿入する際の作業性が良好な梁補強金具および梁補強構造を提供することを目的とする。 SUMMARY OF THE INVENTION It is an object of the present invention to provide a beam reinforcing metal fitting and a beam reinforcing structure which are easy to work when inserted into a through-hole of a beam.
前述した目的を達成するため、第1の発明は、ウェブに貫通孔が形成された梁を補強するための梁補強金具であって、フランジ部と、前記フランジ部の一方の側に突出して前記貫通孔に挿入される筒状の本体部と、を具備し、前記本体部は周方向において同一の長さではなく、前記本体部の中心線によって、前記本体部の長い領域と短い領域とに区分可能であることを特徴とする梁補強金具である。 In order to achieve the above object, a first invention is a beam reinforcing fitting for reinforcing a beam having through holes formed in a web, comprising: a flange portion; a cylindrical main body inserted into the through-hole, wherein the main body does not have the same length in the circumferential direction, but the long region and the short region of the main body are divided by the center line of the main body. The beam reinforcing metal fitting is characterized by being separable.
前記本体部は、側面視においてテーパ状に長さが変化してもよい。
あるいは、前記本体部は、側面視において段差を有し、段差によって長さが変化してもよい。
The length of the main body portion may change in a tapered shape when viewed from the side.
Alternatively, the main body portion may have a step in a side view, and the length may vary depending on the step.
第1の発明の梁補強金具は、本体部が周方向において同一の長さではなく本体部の中心線によって本体部の長い領域と短い領域とに区分可能なので、貫通孔の軸方向に対して本体部の軸方向を傾けた状態として、本体部の長い領域から貫通孔への挿入を開始することができる。その後、本体部の長い領域を貫通孔に沿わせて挿入を進めれば、本体部の短い領域を挿入する前に貫通孔の軸方向と本体部の軸方向とを容易に一致させることができるので、貫通孔に本体部の全体をスムーズに挿入できる。 In the beam reinforcing metal fitting of the first invention, the main body portion does not have the same length in the circumferential direction, but can be divided into a long region and a short region of the main body portion by the center line of the main body portion. With the main body tilted in the axial direction, insertion into the through-hole can be started from the long region of the main body. Thereafter, by inserting the long region of the main body along the through-hole, the axial direction of the through-hole can be easily aligned with the axial direction of the main body before inserting the short region of the main body. Therefore, the entire body can be smoothly inserted into the through hole.
本体部の長さが側面視においてテーパ状に変化したり、本体部の長さが側面視において段差によって変化したりすれば、本体部を長い領域と短い領域とに容易に区分することができる。 If the length of the main body changes in a tapered shape when viewed from the side, or if the length of the main body changes due to steps when viewed from the side, the main body can be easily divided into a long region and a short region. .
第2の発明は、第1の発明の梁補強金具を用いた梁補強構造であって、前記梁補強金具の前記本体部が、梁のウェブに形成された貫通孔に挿入された状態で、前記梁補強金具が前記梁に溶接されることを特徴とする梁補強構造である。 A second invention is a beam reinforcing structure using the beam reinforcing metal fitting of the first invention, wherein the main body portion of the beam reinforcing metal fitting is inserted into a through hole formed in the web of the beam, The beam reinforcing structure is characterized in that the beam reinforcing metal fitting is welded to the beam.
前記本体部の長さの長い領域では、前記本体部が前記ウェブの背面側に突出し、
前記本体部の長さの短い領域では、前記本体部が前記ウェブの背面側に突出していなくてもよい。
in the long region of the body portion, the body portion protrudes to the back side of the web;
In the short region of the body portion, the body portion may not protrude to the rear side of the web.
第2の発明によれば、本体部が周方向において同一の長さではなく、本体部の中心線によって本体部の長い領域と短い領域とに区分可能な梁補強金具を用いるので、本体部の長い領域を貫通孔に沿わせて挿入を開始することで本体部の全体が貫通孔にスムーズに挿入される。 According to the second aspect of the invention, since the main body does not have the same length in the circumferential direction but uses a beam reinforcing metal fitting that can be divided into a long region and a short region of the main body by the center line of the main body, By starting to insert the long region along the through-hole, the entire main body can be smoothly inserted into the through-hole.
本体部の短い領域がウェブの背面側に突出しないようにすれば、本体部を傾けた状態で本体部の大部分を貫通孔に挿入することができる。 If the short region of the main body does not protrude to the rear side of the web, most of the main body can be inserted into the through-hole with the main body tilted.
本発明によれば、梁の貫通孔に挿入する際の作業性が良好な梁補強金具および梁補強構造を提供することができる。 ADVANTAGE OF THE INVENTION According to this invention, the beam reinforcement metal fitting and beam reinforcement structure with the favorable workability|operativity at the time of inserting into the through-hole of a beam can be provided.
以下、本発明の実施の形態について説明する。図1は、本実施形態にかかる梁補強金具1を示す斜視図である。梁補強金具1は、本体部3、フランジ部5等から構成される。梁補強金具1は、ウェブに貫通孔が形成された梁を補強するための部材である。 BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below. FIG. 1 is a perspective view showing a beam reinforcing metal fitting 1 according to this embodiment. The beam reinforcing metal fitting 1 is composed of a body portion 3, a flange portion 5, and the like. A beam reinforcing metal fitting 1 is a member for reinforcing a beam having through holes formed in a web.
梁補強金具1は、例えば鋼材やステンレス鋼などの金属製の部材である。梁補強金具1は、全体としてリング状の部材であり、配管等が貫通する配管孔を有している。本体部3は、フランジ部5の一方の側に突出して設けられる。本体部3は、後述する梁の貫通孔に挿入される筒状の部位である。 The beam reinforcing metal fitting 1 is, for example, a member made of metal such as steel or stainless steel. The beam reinforcing metal fitting 1 is a ring-shaped member as a whole, and has a piping hole through which piping or the like passes. The body portion 3 is provided so as to protrude from one side of the flange portion 5 . The body portion 3 is a cylindrical portion that is inserted into a through hole of a beam, which will be described later.
本体部3は、周方向において同一の長さではない。すなわち本体部3は筒の軸方向の長さが周方向の位置によって異なる。本体部3は、側面視においてテーパ状に長さが変化する。本体部3は、中心線(図1に点線で示す径方向の線)によって、筒の軸方向の長さの長い領域Xと短い領域Yとに区分可能である。 The body portion 3 does not have the same length in the circumferential direction. That is, the length of the main body 3 in the axial direction of the cylinder varies depending on the position in the circumferential direction. The length of the main body portion 3 changes in a tapered shape when viewed from the side. The body portion 3 can be divided into a long region X and a short region Y in the axial direction of the cylinder by a center line (a radial line indicated by a dotted line in FIG. 1).
なお、フランジ部5は本体部3に対して外径が大きい。本体部3及びフランジ部5の内径は略同一であり、内周面には凹凸は形成されない。 Note that the flange portion 5 has a larger outer diameter than the body portion 3 . The inner diameters of the main body portion 3 and the flange portion 5 are substantially the same, and no unevenness is formed on the inner peripheral surface.
次に、梁補強金具1を用いた梁補強構造10について説明する。図2(a)は、梁補強構造10をウェブ15の背面15b側から見た斜視図であり、図2(b)は、梁補強構造10をウェブ15の正面15a側から見た斜視図である。また、図3は、梁補強構造10の正面図であり、図4は、図3のA-A線断面図である。 Next, the beam reinforcing structure 10 using the beam reinforcing metal fittings 1 will be described. 2(a) is a perspective view of the beam reinforcing structure 10 viewed from the rear surface 15b side of the web 15, and FIG. 2(b) is a perspective view of the beam reinforcing structure 10 viewed from the front surface 15a side of the web 15. be. 3 is a front view of the beam reinforcing structure 10, and FIG. 4 is a sectional view taken along the line AA of FIG.
梁11は、ウェブ15の上下にフランジ13を有するH鋼である。ウェブ15には、配管等を通すための貫通孔17が形成される。梁補強金具1は貫通孔17に配置される。前述したように、貫通孔17には、梁補強金具1の本体部3が挿入される。フランジ部5は、貫通孔17の縁部近傍のウェブ15に面接触する。これにより、貫通孔17の縁にバリ等がある場合にも、梁補強金具1で隠すことができる。 The beam 11 is H steel with flanges 13 above and below the web 15 . The web 15 is formed with a through hole 17 for passing a pipe or the like. The beam reinforcing metal fitting 1 is arranged in the through hole 17 . As described above, the body portion 3 of the beam reinforcing metal fitting 1 is inserted into the through hole 17 . The flange portion 5 makes surface contact with the web 15 near the edge of the through hole 17 . Thus, even if there is a burr or the like on the edge of the through hole 17, it can be hidden by the beam reinforcing metal fitting 1. - 特許庁
梁補強金具1の本体部3の長さの長い領域Xでは、本体部3の全体がウェブ15の背面15b側に突出する。本体部3の長さの短い領域Yでは、本体部3の少なくも一部がウェブ15の背面15b側に突出しない。 In the long region X of the main body portion 3 of the beam reinforcing metal fitting 1, the main body portion 3 as a whole protrudes toward the rear surface 15b of the web 15. As shown in FIG. At least a portion of the body portion 3 does not protrude toward the rear surface 15 b of the web 15 in the short region Y of the body portion 3 .
梁補強金具1は、ウェブ15に対して溶接によって接合される。本実施形態では、フランジ部5の外周部が、ウェブ15に対して全周にわたって溶接される。すなわち、溶接部19は、フランジ部5の外周部とウェブ15の正面15aとの間に形成される。 The beam reinforcing metal fitting 1 is joined to the web 15 by welding. In this embodiment, the outer peripheral portion of the flange portion 5 is welded to the web 15 over the entire circumference. That is, the welded portion 19 is formed between the outer peripheral portion of the flange portion 5 and the front surface 15 a of the web 15 .
次に、梁補強金具1を用いた梁補強方法(梁補強構造10の施工方法)について説明する。図5は、梁補強金具1の貫通孔17への挿入方法を示す図である。まず、梁11をウェブ15の正面15a側が上向きになるように作業ヤードに仮置きする。 Next, a beam reinforcement method using the beam reinforcement fitting 1 (construction method of the beam reinforcement structure 10) will be described. 5A and 5B are diagrams showing a method of inserting the beam reinforcing metal fitting 1 into the through hole 17. FIG. First, the beam 11 is temporarily placed in the working yard so that the front 15a side of the web 15 faces upward.
そして、図5(a)に示すように、貫通孔17の軸方向に対して本体部3の軸方向を傾けた状態として、梁補強金具1の本体部3の領域Xのうち最も長い部分の端部を梁11のウェブ15の正面15a側から貫通孔17に挿入する。その後、本体部3の長い領域Xをガイドとして貫通孔17の内周面に沿わせつつ、梁補強金具1を矢印Bに示す方向に移動させる。 Then, as shown in FIG. 5(a), in a state in which the axial direction of the body portion 3 is inclined with respect to the axial direction of the through hole 17, the longest portion of the region X of the body portion 3 of the beam reinforcing metal fitting 1 is The end portion is inserted into the through hole 17 from the front surface 15a side of the web 15 of the beam 11 . After that, the beam reinforcing metal fitting 1 is moved in the direction indicated by the arrow B while the long region X of the main body portion 3 is used as a guide along the inner peripheral surface of the through hole 17 .
長い領域Xをガイドとして本体部3を貫通孔17にある程度まで挿入したら、短い領域Yを挿入する前に、図5(b)に示すように本体部3を矢印Cの方向に回転させることにより貫通孔17の軸方向と本体部3の軸方向とを一致させる。そして、短い領域Yを挿入して本体部3の全体を貫通孔17に配置する。 After inserting the main body 3 into the through hole 17 to some extent using the long region X as a guide, before inserting the short region Y, the main body 3 is rotated in the direction of arrow C as shown in FIG. The axial direction of the through hole 17 and the axial direction of the body portion 3 are aligned. Then, the entire body portion 3 is arranged in the through hole 17 by inserting the short region Y. As shown in FIG.
この際、梁補強金具1のフランジ部5は、梁11に設けられた貫通孔17よりも大きな外径を有している。また、本体部3は、梁11に設けられた貫通孔17の径よりも小さい外径を有している。このため、本体部3を貫通孔17に挿入すると、フランジ部5をウェブ15に接触させることができる。すなわち、フランジ部5は梁補強金具1を貫通孔17に挿入する際、軸方向の位置決めに使われる。 At this time, the flange portion 5 of the beam reinforcing metal fitting 1 has a larger outer diameter than the through hole 17 provided in the beam 11 . Further, the body portion 3 has an outer diameter smaller than the diameter of the through hole 17 provided in the beam 11 . Therefore, when the body portion 3 is inserted into the through hole 17 , the flange portion 5 can be brought into contact with the web 15 . That is, the flange portion 5 is used for axial positioning when inserting the beam reinforcing metal fitting 1 into the through hole 17 .
梁補強金具1の位置が決まったら、ウェブ15の正面15a側からフランジ部5の外周部とウェブ15の正面15aとの間に溶接部19を形成して、梁補強金具1をウェブ15に固定する。溶接は例えば被覆アーク溶接で行われる。 After the position of the beam reinforcing metal fitting 1 is determined, a welded portion 19 is formed between the outer peripheral portion of the flange portion 5 and the front face 15a of the web 15 from the front face 15a side of the web 15 to fix the beam reinforcing metal fitting 1 to the web 15. do. Welding is performed, for example, by shielded arc welding.
以上により、梁補強構造10を得ることができる。梁補強金具1によって、梁11の貫通孔17の近傍における曲げ耐力を向上させることができる。 As described above, the beam reinforcing structure 10 can be obtained. The beam reinforcing metal fitting 1 can improve the bending strength of the beam 11 in the vicinity of the through hole 17 .
以上、本実施の形態によれば、梁補強金具1の本体部3が周方向において同一の長さではなく本体部3の中心線によって本体部3の長い領域Xと短い領域Yとに区分可能なので、貫通孔17の軸方向に対して本体部3の軸方向を傾けた状態として、本体部3の長い領域Xから梁補強金具1の貫通孔17への挿入を開始することができる。その後、本体部3の長い領域Xをガイドとして貫通孔17に沿わせつつ挿入を進めれば、本体部3の短い領域Yを挿入する前に貫通孔17の軸方向と本体部3の軸方向とを容易に一致させることができる。そのため、本体部3の短い領域Yを貫通孔17に挿入する際に貫通孔17の周囲に引っ掛かることがなく、梁補強金具1を貫通孔17にスムーズに配置できる。 As described above, according to the present embodiment, the main body portion 3 of the beam reinforcing metal fitting 1 does not have the same length in the circumferential direction, but can be divided into the long region X and the short region Y by the center line of the main body portion 3. Therefore, the insertion of the beam reinforcing metal fitting 1 into the through-hole 17 can be started from the long region X of the main body 3 with the axial direction of the main body 3 inclined with respect to the axial direction of the through-hole 17 . After that, if the body portion 3 is inserted along the through hole 17 using the long region X of the body portion 3 as a guide, the axial direction of the through hole 17 and the axial direction of the body portion 3 are inserted before the short region Y of the body portion 3 is inserted. can be easily matched. Therefore, when inserting the short region Y of the body portion 3 into the through hole 17 , the beam reinforcing metal fitting 1 can be smoothly arranged in the through hole 17 without being caught around the through hole 17 .
また、梁補強構造10は、本体部3の短い領域Yがウェブ15の背面15b側に突出しないので、本体部3を傾けた状態で本体部3の大部分を貫通孔17に挿入することができる。そのため、本体部3の全体が背面15b側に突出している場合と比較して、貫通孔17への挿入が容易である。 In addition, in the beam reinforcing structure 10, since the short region Y of the body portion 3 does not protrude toward the rear surface 15b of the web 15, most of the body portion 3 can be inserted into the through hole 17 while the body portion 3 is tilted. can. Therefore, insertion into the through-hole 17 is easier than in the case where the main body portion 3 as a whole protrudes toward the back surface 15b.
(第2の実施形態)
次に、第2の実施形態について説明する。図6は、梁補強構造10aを示す斜視図である。なお、以下の説明において、梁補強金具1及び梁補強構造10と同様の機能を奏する構成には、図1~図5と同一の符号を付して、重複する説明を省略する。
(Second embodiment)
Next, a second embodiment will be described. FIG. 6 is a perspective view showing the beam reinforcing structure 10a. In the following description, structures having the same functions as those of the beam reinforcing metal fitting 1 and the beam reinforcing structure 10 are denoted by the same reference numerals as in FIGS. 1 to 5, and duplicate descriptions are omitted.
図6に示す梁補強構造10aは、梁補強金具1aを用いる点で梁補強金具1と構成が異なる。 A beam reinforcing structure 10a shown in FIG. 6 differs from the beam reinforcing metal fitting 1 in that the beam reinforcing metal fitting 1a is used.
梁補強金具1aは、梁補強金具1と同様に周方向において同一の長さではない。本体部3は、側面視において段差を有し、段差によって長さが変化する。本体部3は、中心線(図6に点線で示す軸方向の線)によって、筒の軸方向の長さの長い領域Xと短い領域Yとに区分可能である。本体部3は、領域Xにおける長さが一定であり、領域Yにおける長さも一定である。 The beam reinforcing metal fitting 1a, like the beam reinforcing metal fitting 1, does not have the same length in the circumferential direction. The body portion 3 has steps in a side view, and the length changes according to the steps. The main body 3 can be divided into a long region X and a short region Y in the axial direction of the cylinder by a center line (an axial line indicated by a dotted line in FIG. 6). The body portion 3 has a constant length in the region X, and a constant length in the region Y as well.
梁補強金具1aの本体部3の長さの長い領域Xでは、本体部3の全体がウェブ15の背面15b側に突出する。また、本体部3の長さの短い領域Yでは、本体部3の全体がウェブ15の背面15b側に突出しない。 In the long region X of the main body portion 3 of the beam reinforcing metal fitting 1a, the main body portion 3 as a whole protrudes toward the rear surface 15b of the web 15. As shown in FIG. Further, in the region Y where the length of the main body portion 3 is short, the main body portion 3 as a whole does not protrude toward the rear surface 15 b of the web 15 .
梁補強構造10aを施工するには、貫通孔17の軸方向に対して本体部3の軸方向を傾けた状態として、梁補強金具1aの本体部3の領域Xのうち中心線から最も離れた部分の端部を貫通孔17に挿入する。その後、本体部3を長い領域Xをガイドとして貫通孔17の内周面に沿わせつつ貫通孔17にある程度まで挿入したら、本体部3を回転させて貫通孔17の軸方向と本体部3の軸方向とを一致させる。そして、短い領域Yを挿入して本体部3の全体を貫通孔17に配置する。 In order to construct the beam reinforcing structure 10a, the axial direction of the main body portion 3 is tilted with respect to the axial direction of the through hole 17, and the region X of the main body portion 3 of the beam reinforcing metal fitting 1a that is the farthest from the center line. Insert the end of the section into the through hole 17 . After that, after inserting the body portion 3 into the through hole 17 to some extent along the inner peripheral surface of the through hole 17 using the long region X as a guide, the body portion 3 is rotated to move the body portion 3 between the axial direction of the through hole 17 and the body portion 3. match the axial direction. Then, the entire body portion 3 is arranged in the through hole 17 by inserting the short region Y. As shown in FIG.
第2の実施形態においても、梁補強金具1aの本体部3が周方向において同一の長さではないので、第1の実施形態と同様の効果を得ることができる。 Also in the second embodiment, since the main body portion 3 of the beam reinforcing metal fitting 1a does not have the same length in the circumferential direction, the same effect as in the first embodiment can be obtained.
以上、添付図を参照しながら、本発明の実施の形態を説明したが、本発明の技術的範囲は、前述した実施の形態に左右されない。当業者であれば、特許請求の範囲に記載された技術的思想の範疇内において各種の変更例または修正例に想到し得ることは明らかであり、それらについても当然に本発明の技術的範囲に属するものと了解される。 Although the embodiments of the present invention have been described above with reference to the accompanying drawings, the technical scope of the present invention is not influenced by the above-described embodiments. It is obvious that a person skilled in the art can conceive various modifications or modifications within the scope of the technical idea described in the claims, and these are naturally within the technical scope of the present invention. be understood to belong to
例えば、梁補強金具の本体部3は円筒状に限らない。例えば貫通孔が角形である場合、角筒状の本体部3の端部にフランジ部5が形成された梁補強金具を用いてもよい。 For example, the main body portion 3 of the beam reinforcing metal fitting is not limited to a cylindrical shape. For example, when the through-hole is rectangular, a beam reinforcing metal fitting having a flange portion 5 formed at the end portion of the main body portion 3 in the shape of a rectangular tube may be used.
また、梁補強構造では、梁補強金具の本体部3の長さの短い領域Yがウェブ15の背面15b側に突出していてもよい。この場合も、貫通孔17の軸方向に対して本体部3の軸方向を傾けた状態で本体部3の長い領域Xをガイドとして梁補強金具1の貫通孔17への挿入を進めた後、貫通孔17の軸方向と本体部3の軸方向とを一致させて本体部3の短い領域Yを貫通孔17に挿入することができる。 In addition, in the beam reinforcing structure, the short region Y of the main body portion 3 of the beam reinforcing metal fitting may protrude toward the rear surface 15 b of the web 15 . In this case as well, after inserting the beam reinforcing metal fitting 1 into the through-hole 17 with the long region X of the main body 3 as a guide in a state in which the axial direction of the main body 3 is inclined with respect to the axial direction of the through-hole 17, The short region Y of the body portion 3 can be inserted into the through hole 17 by aligning the axial direction of the through hole 17 with the axial direction of the body portion 3 .
梁補強構造10、10aでは、本体部3の長い領域Xが貫通孔17の上半部に位置するように梁補強金具を配置したが、梁補強金具の向きはこれに限らない。例えば、本体部3の短い領域Yが貫通孔17の上半部に位置するように梁補強金具を配置してもよい。 In the beam reinforcing structures 10 and 10a, the beam reinforcing metal fittings are arranged so that the long region X of the main body portion 3 is located in the upper half of the through hole 17, but the orientation of the beam reinforcing metal fittings is not limited to this. For example, the beam reinforcing metal fitting may be arranged so that the short region Y of the main body portion 3 is positioned in the upper half portion of the through hole 17 .
また、本体部3の長い領域Xと短い領域Yとの境界位置は、必ずしも中心線Oの位置でなくてもよい。例えば、段差を形成する場合には、段差の位置は本体部3の中心線Oの位置でなくてもよく、中心線Oからずれた位置(例えば図6の上下方向にずれた位置)であってもよい。また、テーパ形状とする場合にも、本体部3の全体がテーパ形状でなくてもよく、例えば、周方向の所定の領域は、本体部3の長さが一定で、残りの部分をテーパ状に短くしてもよい。すなわち、本体部3の中心線Oによって、本体部3の長い領域Xと短い領域Yとに区分可能とは、中心線Oの一方の側の本体部3の平均長さが長く、他方の側の本体部3の平均長さが相対的に短くなるように区分可能であればよい。 Further, the boundary position between the long region X and the short region Y of the body portion 3 does not necessarily have to be the center line O position. For example, when forming a step, the position of the step does not have to be the position of the center line O of the main body 3, but may be a position shifted from the center line O (for example, a position shifted in the vertical direction in FIG. 6). may Further, even when the tapered shape is used, the entire body portion 3 does not have to be tapered. can be shortened to That is, being able to divide the main body 3 into a long region X and a short region Y by the center line O of the main body 3 means that the average length of the main body 3 on one side of the center line O is long and the average length on the other side is long. It suffices if it can be divided so that the average length of the main body portion 3 of is relatively short.
