ダボ穴３２及びダボ穴１２が本体３０の上面３１及び支持材１０の下面１１にそれぞれ形成されている。ダボ４０がダボ穴３２及びダボ穴１２に嵌め込まれている。ダボ４０はステンレス鋼又はアルミニウム合金等のような金属材料からなる。 Dowel holes 32 and 12 are formed on the upper surface 31 of the main body 30 and the lower surface 11 of the support member 10, respectively. Dowels 40 are fitted into dowel holes 32 and 12. Dowels 40 are made of a metal material such as stainless steel or aluminum alloy.

通し孔４１がダボ４０の中心軸方向に対して垂直な方向にダボ４０の上部を貫通する。ダボ４０の中心軸方向は、ダボ４０がダボ穴１２，３２に差し込まれる方向である。一方、通し孔１５が支持材１０の側面１３からダボ穴１２を経由して側面１４まで幅方向に貫通する。通し孔１５と通し孔４１が一続きに連なっており、ステンレス鋼製又はアルミニウム合金製等のように金属製の第１支持ピン５０がこれら通し孔１５，４１に嵌め込まれている。第１支持ピン５０が通し孔１５，４１に挿入されていることは、ダボ穴１２からダボ４０の抜けを防止する。第１支持ピン５０がその外周面に凹凸を有し、凹凸が通し孔１５，４１から第１支持ピン５０の抜け防止に寄与してもよい。 The through-hole 41 penetrates the top of the dowel 40 in a direction perpendicular to the central axis direction of the dowel 40. The central axis direction of the dowel 40 is the direction in which the dowel 40 is inserted into the dowel holes 12 and 32. Meanwhile, the through-hole 15 penetrates the side surface 13 of the support material 10 through the dowel hole 12 to the side surface 14 in the width direction. The through-holes 15 and 41 are continuous, and a first support pin 50 made of metal, such as stainless steel or aluminum alloy, is fitted into these through-holes 15 and 41. The insertion of the first support pin 50 into the through-holes 15 and 41 prevents the dowel 40 from coming out of the dowel hole 12. The first support pin 50 may have irregularities on its outer surface, and these irregularities may contribute to preventing the first support pin 50 from coming out of the through-holes 15 and 41.

通し孔４２がダボ４０の中心軸方向に対して垂直な方向にダボ４０の上部を貫通する。一方、通し孔３５が本体３０の側面３３からダボ穴３２を経由して側面３４まで幅方向に貫通する。通し孔３５と通し孔４２が一続きに連なっており、ステンレス鋼製又はアルミニウム合金製等のように金属製の第２支持ピン６０がこれら通し孔３５，４２に嵌め込まれている。第２支持ピン６０が通し孔３５，４２に挿入されていることは、ダボ穴３２からダボ４０の抜けを防止する。第２支持ピン６０がその外周面に凹凸を有し、凹凸が通し孔３５，４２から第２支持ピン６０の抜け防止に寄与してもよい。
本体３０はダボ４０及び支持ピン５０，６０によって吊り具２０に固定されている。 The through hole 42 penetrates the top of the dowel 40 in a direction perpendicular to the central axis of the dowel 40. On the other hand, the through hole 35 penetrates the widthwise from the side surface 33 of the main body 30 through the dowel hole 32 to the side surface 34. The through holes 35 and 42 are connected in a continuous line, and a second support pin 60 made of metal, such as stainless steel or aluminum alloy, is fitted into these through holes 35 and 42. The insertion of the second support pin 60 into the through holes 35 and 42 prevents the dowel 40 from coming out of the dowel hole 32. The second support pin 60 may have irregularities on its outer surface, and these irregularities may contribute to preventing the second support pin 60 from coming out of the through holes 35 and 42.
The main body 30 is fixed to the suspension device 20 by dowels 40 and support pins 50 and 60.

第１支持ピン５０の両端が通し孔１５の両端から僅かに突き出ている。第２支持ピン６０の両端が通し孔３５の両端から僅かに突き出ている。 Both ends of the first support pin 50 protrude slightly from both ends of the through hole 15. Both ends of the second support pin 60 protrude slightly from both ends of the through hole 35.

ステンレス鋼製又はアルミニウム合金製等のように金属製の補強プレート７０が支持材１０の側面１３及び本体３０の側面３３に面接触する。補強プレート７０が複数のビス７９によって支持材１０の側面１３及び本体３０の側面３３に留められている。補強プレート７０には２つの穴７１，７２が形成され、支持ピン５０，６０の端が穴７１，７２にそれぞれ差し込まれている。 A metal reinforcing plate 70, such as one made of stainless steel or aluminum alloy, makes surface contact with the side surface 13 of the support member 10 and the side surface 33 of the main body 30. The reinforcing plate 70 is fastened to the side surface 13 of the support member 10 and the side surface 33 of the main body 30 by multiple screws 79. Two holes 71 and 72 are formed in the reinforcing plate 70, and the ends of support pins 50 and 60 are inserted into the holes 71 and 72, respectively.

なお、穴７１，７２が補強プレート７０に形成されておらず、支持ピン５０，６０の端が通し孔１５の両端から突き出ず、支持ピン５０，６０の端が補強プレート７０に突き当てられてもよい。このような補強プレート７０は支持ピン５０，６０の抜け防止に寄与する。 Furthermore, holes 71 and 72 may not be formed in the reinforcing plate 70, and the ends of the support pins 50 and 60 may not protrude from both ends of the through-hole 15, but rather abut against the reinforcing plate 70. Such a reinforcing plate 70 contributes to preventing the support pins 50 and 60 from coming loose.

ステンレス鋼製又はアルミニウム合金製等のように金属製の補強プレート８０が支持材１０の側面１４及び本体３０の側面３４に面接触する。補強プレート８０が複数のビス８９によって支持材１０の側面１４及び本体３０の側面３４に留められている。補強プレート８０には２つの穴が形成され、支持ピン５０，６０の端が２つの穴にそれぞれ差し込まれている。 A metal reinforcing plate 80, such as one made of stainless steel or aluminum alloy, makes surface contact with the side surface 14 of the support member 10 and the side surface 34 of the main body 30. The reinforcing plate 80 is fastened to the side surface 14 of the support member 10 and the side surface 34 of the main body 30 by multiple screws 89. Two holes are formed in the reinforcing plate 80, and the ends of support pins 50 and 60 are inserted into these two holes, respectively.

なお、穴が補強プレート８０に形成されておらず、支持ピン５０，６０の端が通し孔３５の両端から突き出ず、支持ピン５０，６０の端が補強プレート８０に突き当てられてもよい。このような補強プレート８０は支持ピン５０，６０の抜け防止に寄与する。 Furthermore, the reinforcing plate 80 may not have holes, and the ends of the support pins 50 and 60 may not protrude from both ends of the through-holes 35, but rather abut against the reinforcing plate 80. Such a reinforcing plate 80 contributes to preventing the support pins 50 and 60 from coming loose.

第１支持ピン５０が補強プレート７０と補強プレート８０のどちらかと一体形成されてもよい。第２支持ピン６０が補強プレート７０と補強プレート８０のどちらかと一体形成されてもよい。支持ピン５０，６０の両方が補強プレート７０と補強プレート８０のどちらかと一体形成されてもよい。支持ピン５０，６０のうち一方が補強プレート７０と一体形成され、他方が補強プレート８０と一体形成されてもよい。 The first support pin 50 may be integrally formed with either the reinforcing plate 70 or the reinforcing plate 80. The second support pin 60 may be integrally formed with either the reinforcing plate 70 or the reinforcing plate 80. Both support pins 50 and 60 may be integrally formed with either the reinforcing plate 70 or the reinforcing plate 80. One of the support pins 50 or 60 may be integrally formed with the reinforcing plate 70, and the other with the reinforcing plate 80.

補強プレート７０，８０は、ダボ４０及び支持ピン５０，６０による吊り具２０と本体３０の相互固定を補強する。補強プレート７０，８０は、本体３０のがたつきを防止する。 The reinforcing plates 70 and 80 reinforce the mutual fixing of the suspension device 20 and the main body 30 using the dowels 40 and support pins 50 and 60. The reinforcing plates 70 and 80 also prevent the main body 30 from rattling.

なお、補強材が補強プレート７０，８０のように板状であるところ、補強材が補強プレート７０，８０よりも十分に厚いブロック状であってもよい。 Furthermore, while the reinforcing material is typically plate-shaped, as in the reinforcing plates 70 and 80, it may also be in the form of a block significantly thicker than the reinforcing plates 70 and 80.

本体３０の下面３６が天井ボード５の裏に突き当てられている。雌ねじ３７が本体３０の下面３６に形成されている。ホール５ａが、雌ねじ３７に重なる位置において天井ボード５に形成されている。 The lower surface 36 of the main body 30 is abutted against the back of the ceiling board 5. A female thread 37 is formed on the lower surface 36 of the main body 30. A hole 5a is formed in the ceiling board 5 at a position overlapping the female thread 37.

連結具９０は、ステンレス鋼製又はアルミニウム合金製のように金属製のリングフックである。連結具９０は、リングフックではなくて、金属製のＪ字型フック、Ｌ字型フック、Ｃ字型フック、シャックル、挟み具、引っ掛け具又はクロスビットであってもよい。連結具９０は雄ねじ９１を有する。雄ねじ９１が天井ボード５のホール５ａに挿入されて、雌ねじ３７にねじ留めされている。雄ねじ９１は緩み留め加工されてもよい。 The connector 90 is a metal ring hook, such as one made of stainless steel or aluminum alloy. The connector 90 may also be a metal J-shaped hook, L-shaped hook, C-shaped hook, shackle, clamp, hook, or cross bit, instead of a ring hook. The connector 90 has a male screw 91. The male screw 91 is inserted into the hole 5a of the ceiling board 5 and screwed into the female screw 37. The male screw 91 may be treated to prevent loosening.

なお、第１支持ピン５０の数が２以上であってもよい。つまり、複数の第１支持ピン５０がダボ４０の中心軸方向に対して直交する方向に補強プレート７０、支持材１０、ダボ４０及び補強プレート８０を貫通してもよい。これら第１支持ピン５０は上下方向に間隔を置いて並んでもよい。
第２支持ピン６０の数も２以上であってもよい。つまり、複数の第２支持ピン６０がダボ４０の中心軸方向に対して直交する方向に補強プレート７０、本体３０、ダボ４０及び補強プレート８０を貫通してもよい。これら第２支持ピン６０は上下方向に間隔を置いて並んでもよい。 Furthermore, the number of first support pins 50 may be two or more. In other words, multiple first support pins 50 may penetrate the reinforcing plate 70, support material 10, dowel 40, and reinforcing plate 80 in a direction perpendicular to the central axis direction of the dowel 40. These first support pins 50 may be arranged at intervals in the vertical direction.
The number of second support pins 60 may also be two or more. In other words, multiple second support pins 60 may penetrate the reinforcing plate 70, the main body 30, the dowel 40, and the reinforcing plate 80 in a direction perpendicular to the central axis direction of the dowel 40. These second support pins 60 may be arranged at intervals in the vertical direction.

ダボ４０を支持材１０のダボ穴１２及び本体３０のダボ穴３２及びに嵌め込むとともに、本体３０の上面３１を支持材１０の下面１１に当てる。 <2. Installation Method of Lifting Equipment>
The dowel pins 40 are fitted into the dowel holes 12 of the support material 10 and the dowel holes 32 of the main body 30, and the upper surface 31 of the main body 30 is brought into contact with the lower surface 11 of the support material 10.

第１支持ピン５０を支持材１０の側方から通し孔１５及び通し孔４１に打ち込んで、第１支持ピン５０を幅方向に支持材１０及びダボ４０に貫通させる。
第２支持ピン６０を支持材１０の側方から通し孔３５及び通し孔４２に打ち込んで、第２支持ピン６０を幅方向に支持材１０及びダボ４０に貫通させる。 The first support pin 50 is driven into the through-hole 15 and through-hole 41 from the side of the support material 10, so that the first support pin 50 penetrates the support material 10 and the dowel 40 in the width direction.
The second support pin 60 is driven into the through holes 35 and 42 from the side of the support material 10, so that the second support pin 60 penetrates the support material 10 and the dowel 40 in the width direction.

補強プレート７０を支持材１０及び本体３０の側面１３，３３に当てて、支持ピン５０，６０の端を補強プレート７０の穴７１，７２にそれぞれ差し込む。複数のビス７９によって補強プレート７０を支持材１０の側面１３に留める。複数のビス７９によって補強プレート７０を本体３０の側面３３に留める。
補強プレート８０を支持材１０及び本体３０の側面１４，３４に当てて、支持ピン５０，６０の端を補強プレート８０の２つの穴にそれぞれ差し込む。複数のビス８９によって補強プレート８０を支持材１０の側面１４に留める。複数のビス８９によって補強プレート８０を本体３０の側面３４に留める。
なお、手順を変更してもよい。例えば、支持材１０及び本体３０への補強プレート７０，８０の固定後に、第１支持ピン５０を補強プレート７０の穴７１、通し孔１５、通し孔４１及び補強プレート８０の穴に打ち込み、第２支持ピン６０を補強プレート７０の穴７２、通し孔３５、通し孔４２及び補強プレート８０の穴に打ち込んでもよい。支持ピン５０，６０の打ち込みに利用されるハンマー等が補強プレート７０，８０に当たることから、打撃力による支持材１０の損傷が防止される。 The reinforcing plate 70 is placed against the sides 13 and 33 of the support material 10 and the main body 30, and the ends of the support pins 50 and 60 are inserted into the holes 71 and 72 of the reinforcing plate 70, respectively. The reinforcing plate 70 is fastened to the side 13 of the support material 10 with multiple screws 79. The reinforcing plate 70 is fastened to the side 33 of the main body 30 with multiple screws 79.
The reinforcing plate 80 is placed against the sides 14 and 34 of the support material 10 and the main body 30, and the ends of the support pins 50 and 60 are inserted into the two holes in the reinforcing plate 80, respectively. The reinforcing plate 80 is fastened to the side 14 of the support material 10 with multiple screws 89. The reinforcing plate 80 is fastened to the side 34 of the main body 30 with multiple screws 89.
The procedure may be modified. For example, after fixing the reinforcing plates 70 and 80 to the support material 10 and the main body 30, the first support pin 50 may be driven into the hole 71, through hole 15, through hole 41 in the reinforcing plate 70 and the hole in the reinforcing plate 80, and the second support pin 60 may be driven into the hole 72 in the reinforcing plate 70, through hole 35, through hole 42 in the reinforcing plate 70 and the hole in the reinforcing plate 80. Since the hammer or other tool used to drive in the support pins 50 and 60 will hit the reinforcing plates 70 and 80, damage to the support material 10 due to impact force is prevented.

その後、野縁３、断熱ボード４及び天井ボード５を設置する。
連結具９０の雄ねじ９１を天井ボード５のホール５ａに通して、雄ねじ９１を雌ねじ９２に留める。 After that, the joists 3, insulation boards 4, and ceiling boards 5 are installed.
The male screw 91 of the connector 90 is passed through the hole 5a of the ceiling board 5 and fastened to the female screw 92.

＜３．まとめ＞
（１）ダボ４０が支持材１０のダボ穴１２に嵌め込まれ、第１支持ピン５０がダボ４０の中心軸方向に対して直交する方向にダボ４０及び支持材１０を貫通するため、ダボ穴１２からのダボ４０の抜けが防止される。同様に、第２支持ピン６０は本体３０のダボ穴３２からのダボ４０の抜けを防止する。これらのダボ４０、第１支持ピン５０及び第２支持ピン６０は支持材１０への本体３０の強固な結合及び固定を実現する。つまり、吊り具２０が支持材１０に確り固定される。 <3. Summary>
(1) The dowel 40 is fitted into the dowel hole 12 of the support material 10, and the first support pin 50 penetrates the dowel 40 and the support material 10 in a direction perpendicular to the central axis of the dowel 40, thereby preventing the dowel 40 from coming out of the dowel hole 12. Similarly, the second support pin 60 prevents the dowel 40 from coming out of the dowel hole 32 of the main body 30. These dowels 40, the first support pin 50 and the second support pin 60 ensure a strong connection and fixation of the main body 30 to the support material 10. In other words, the hanging device 20 is securely fixed to the support material 10.

（２）木製の支持材１０の断面欠損がダボ４０及び第１支持ピン５０によって補われるため、支持材１０の強度低下が起こりにくく、吊り具２０が確り支持材１０に固定される。 (2) Since the cross-sectional defects in the wooden support member 10 are compensated for by the dowel 40 and the first support pin 50, a decrease in the strength of the support member 10 is less likely to occur, and the suspension device 20 is securely fixed to the support member 10.

（３）ダボ穴１２，３２へのダボ４０の嵌め込みと、支持ピン５０，６０の貫通によって、支持材１０への本体３０の結合及び固定が実現されるから、支持材１０への本体３０の結合及び固定にはボルト締めの作業が不要である。よって、簡単に本体３０を支持材１０に固定することができる。 (3) The connection and fixing of the main body 30 to the support material 10 is achieved by inserting the dowels 40 into the dowel holes 12 and 32 and passing the support pins 50 and 60 through them. Therefore, bolting is unnecessary for connecting and fixing the main body 30 to the support material 10. Thus, the main body 30 can be easily fixed to the support material 10.

（４）第１支持ピン５０がダボ４０及び支持材１０を貫通することから、第１支持ピン５０の露出が少ない。第２支持ピン６０がダボ４０及び本体３０を貫通することから、第２支持ピン６０の露出が少ない。これらのことは、吊り具２０の意匠性の向上のみならず、耐火性能及び耐結露性能の向上に寄与する。 (4) Since the first support pin 50 penetrates the dowel 40 and the support material 10, the exposure of the first support pin 50 is minimal. Since the second support pin 60 penetrates the dowel 40 and the main body 30, the exposure of the second support pin 60 is minimal. These features contribute not only to improving the aesthetic design of the suspension device 20, but also to improving its fire resistance and condensation resistance.

（５）本体３０及び支持材１０が補強プレート７０，８０によって補強されて保護される。補強プレート７０，８０が本体３０及び支持材１０の両側にあることから、本体３０及び支持材１０が両側からバランス良く補強される。補強プレート７０，８０は、吊り具２０が支持材１０に確り固定されることに寄与する。 (5) The main body 30 and the support member 10 are reinforced and protected by the reinforcing plates 70 and 80. Since the reinforcing plates 70 and 80 are located on both sides of the main body 30 and the support member 10, the main body 30 and the support member 10 are reinforced evenly from both sides. The reinforcing plates 70 and 80 contribute to the secure fixing of the suspension device 20 to the support member 10.

（６）第１支持ピン５０が支持材１０の側面１３から突き出て、補強プレート７０の穴７１に差し込まれることから、第１支持ピン５０が補強プレート７０によって支えられる。このことは、第１支持ピン５０が支持材１０に及ぼす強度的な悪影響を軽減する。第１支持ピン５０が反対側の補強プレート８０の穴に差し込まれることも同様の効果を実現する。 (6) Since the first support pin 50 protrudes from the side surface 13 of the support material 10 and is inserted into the hole 71 of the reinforcing plate 70, the first support pin 50 is supported by the reinforcing plate 70. This reduces the structural adverse effect that the first support pin 50 has on the support material 10. Inserting the first support pin 50 into the hole of the reinforcing plate 80 on the opposite side achieves a similar effect.

（７）第２支持ピン６０が本体３０の側面３３から突き出て、補強プレート７０の穴７２に差し込まれることから、第２支持ピン６０が補強プレート７０によって支えられる。このことは、第２支持ピン６０が本体３０に及ぼす強度的な悪影響を軽減する。第２支持ピン６０が反対側の補強プレート８０の穴に差し込まれることも同様の効果を実現する。 (7) Since the second support pin 60 protrudes from the side 33 of the main body 30 and is inserted into the hole 72 of the reinforcing plate 70, the second support pin 60 is supported by the reinforcing plate 70. This reduces the structural adverse effect that the second support pin 60 has on the main body 30. Inserting the second support pin 60 into the hole of the reinforcing plate 80 on the opposite side achieves a similar effect.

（８）木材の生産から廃棄及び処分までに使用されるエネルギーは、金属材料又はコンクリート材の生産から廃棄及び処分までに使用されるエネルギーよりも少ない。そのため、支持材１０が設置される建物が木造であれば、その建物は、二酸化炭素の排出量を実質ゼロにするカーボンニュートラルの推進による脱炭素社会の実現と、持続可能な開発目標（Sustainable Development Goals：ＳＤＧｓ）の達成に寄与する。本体３０が木材からなれば、吊り具２０が脱炭素社会の実現とＳＤＧｓの達成に寄与する。 (8) The energy used from the production to the disposal of wood is less than the energy used from the production to the disposal of metal or concrete materials. Therefore, if the building on which the support material 10 is installed is made of wood, that building contributes to the realization of a decarbonized society through the promotion of carbon neutrality, which effectively reduces carbon dioxide emissions to zero, and to the achievement of the Sustainable Development Goals (SDGs). If the main body 30 is made of wood, the suspension device 20 contributes to the realization of a decarbonized society and the achievement of the SDGs.
