各係止片１１ａは、図３乃至図５に示されるように、連結部１３から所定の角度（例えば、約７５°（７５°±５°））で折り曲げられて下方に向かって延出し、下方に向かうにつれて固定部１２に近づくように折り曲げられており、その先端には固定部１２から離間する方向に屈曲した屈曲部１１ｂ（屈曲角度は、例えば、約１３５°（１３５°±５°））が形成されている。屈曲部１１ｂ（突部）は、各係止片１１ａが連結部１３と接続された基端部を起点として、連結部１３に対する傾斜角度が変わるように弾性変形することが可能である。 As shown in FIGS. 3 to 5, each locking piece 11a is bent at a predetermined angle (for example, about 75 ° (75 ° ± 5 °)) from the connecting portion 13 and extends downward. It is bent so as to approach the fixed portion 12 as it goes downward, and at its tip, a bent portion 11b bent in a direction away from the fixed portion 12 (the bending angle is, for example, about 135 ° (135 ° ± 5 °)). ) Is formed. The bent portion 11b (protrusion portion) can be elastically deformed so that the inclination angle with respect to the connecting portion 13 changes, starting from the base end portion where each locking piece 11a is connected to the connecting portion 13.

（固定部１２）
固定部１２は、上下方向において連結部１３よりも下方に位置し、縦ランナー４が固定される上下方向及び幅方向に広がる面を備える部分である。固定部１２は、図２乃至図５に示すように、薄厚（例えば、厚みが約０．５ｍｍ）の鋼板からなり、正面視で矩形形状をなしている。固定部１２の前面には、縦ランナー４の底面がビスＢによって固定される。 (Fixed part 12)
The fixing portion 12 is located below the connecting portion 13 in the vertical direction, and is a portion having a surface extending in the vertical direction and the width direction in which the vertical runner 4 is fixed. As shown in FIGS. 2 to 5, the fixing portion 12 is made of a thin steel plate (for example, having a thickness of about 0.5 mm) and has a rectangular shape when viewed from the front. The bottom surface of the vertical runner 4 is fixed to the front surface of the fixing portion 12 by screws B.

また、本実施形態では、図１に示すように、二つの縦ランナー４が下地金物１０の幅方向において縦ランナー４間に隙間Ｓを空けて並んだ状態で固定部１２の前面に対して固定されることになっている。ここで、縦ランナー４間の隙間Ｓについては、界壁１における遮音性能を確保するのに必要な量（約１０ｍｍ）に設定されている。すなわち、本実施形態では、遮音性能を確保するのに必要な隙間を縦ランナー４間に確保した状態で各縦ランナー４が固定部１２に固定されている。 Further, in the present embodiment, as shown in FIG. 1, the two vertical runners 4 are fixed to the front surface of the fixing portion 12 in a state where the two vertical runners 4 are arranged side by side with a gap S between the vertical runners 4 in the width direction of the base metal 10. Is supposed to be done. Here, the gap S between the vertical runners 4 is set to an amount (about 10 mm) necessary for ensuring the sound insulation performance of the boundary wall 1. That is, in the present embodiment, each vertical runner 4 is fixed to the fixing portion 12 in a state where a gap necessary for ensuring the sound insulation performance is secured between the vertical runners 4.

また、図３及び図６に示すように、下地金物１０は、二つの縦ランナー４を固定部１２に固定する際にガイドとして機能するガイド部１２ａを備えている。具体的には、図６に示すように、固定部１２の横幅方向における中央位置に、連結部１３の前端部から前方へ延出する突起であるガイド部１２ａが形成されている。下地金物１０を作製する際に、鋼板（金属板に相当）を打ち抜いて、連結部１３及び係止部１１に相当する部分と共に折り曲げ加工することで、前方に立て起こされるようにしてガイド部１２ａが形成される。 Further, as shown in FIGS. 3 and 6, the base metal fitting 10 includes a guide portion 12a that functions as a guide when the two vertical runners 4 are fixed to the fixing portion 12. Specifically, as shown in FIG. 6, a guide portion 12a, which is a protrusion extending forward from the front end portion of the connecting portion 13, is formed at the center position of the fixing portion 12 in the lateral width direction. When the base metal 10 is manufactured, a steel plate (corresponding to a metal plate) is punched out and bent together with the portions corresponding to the connecting portion 13 and the locking portion 11 so that the guide portion 12a is raised forward. Is formed.

下地金物１０の横幅方向におけるガイド部１２ａの幅は、固定部１２の幅方向に横並び状態で固定される二つの縦ランナー４の間の隙間（後述する図１０の隙間Ｓ）の設計値（例えば約１０ｍｍ）に対応するように設定されている。後述するように、二つの縦ランナー４を固定部１２に並ぶように固定する際、ガイド部１２ａを挟んで互いに反対の位置に縦ランナー４を固定することで、隣接する二つの縦ランナー４の間の隙間（すなわち、遮音上必要となる隙間）の設計値に相当する隙間Ｓを容易に確保することが可能となる。 The width of the guide portion 12a in the horizontal width direction of the base metal fitting 10 is a design value (for example, a gap S in FIG. 10 described later) between two vertical runners 4 fixed side by side in the width direction of the fixed portion 12. It is set to correspond to about 10 mm). As will be described later, when fixing the two vertical runners 4 so as to line up with the fixing portion 12, by fixing the vertical runners 4 at positions opposite to each other with the guide portion 12a in between, the two vertical runners 4 adjacent to each other It is possible to easily secure a gap S corresponding to the design value of the gap between them (that is, the gap required for sound insulation).

なお、下地金物１０の横幅方向におけるガイド部１２ａの幅を、固定部１２に横並び状態で固定される二つの縦ランナー４の間の隙間の設計値（例えば約１０ｍｍ）よりも若干小さく（例えば約８乃至９ｍｍ）することも可能である。ガイド部１２ａの幅を、縦ランナー４の間の隙間Ｓの設計値よりも若干小さくすることで、下地金物１０の寸法に誤差が生じたり、各部材の配置位置がずれたりしたとしても、二つの縦ランナー４の位置を適宜調整して、二つの縦ランナー４の間の隙間Ｓを設計値に合わせることで、各縦ランナー４を本来の設置位置に精度よく配置することが可能となる。 The width of the guide portion 12a in the horizontal width direction of the base metal fitting 10 is slightly smaller than the design value (for example, about 10 mm) of the gap between the two vertical runners 4 fixed to the fixed portion 12 side by side (for example, about 10 mm). It is also possible to make 8 to 9 mm). By making the width of the guide portion 12a slightly smaller than the design value of the gap S between the vertical runners 4, even if an error occurs in the dimensions of the base metal fitting 10 or the arrangement position of each member shifts, By appropriately adjusting the positions of the two vertical runners 4 and adjusting the gap S between the two vertical runners 4 to the design value, it is possible to accurately arrange each vertical runner 4 at the original installation position.

（連結部１３）
連結部１３は、薄厚の鋼材からなり、下地金物１０の上面を形成し、上面視で矩形形状をなしている。連結部１３は、下地金物１０を鉄骨柱２の係合部Ｋに係合させたときに、係止部１１の基端部及び固定部１２の間（換言すると、鉄骨柱２の側面２ａ及び固定部１２の間）に空間Ｖが形成されるように係止部１１と固定部１２を連結する部分である。ここで、空間Ｖが形成されることで、鉄骨柱２の側面２ａから固定部１２が空間Ｖの厚みだけ離間することとなる。つまり、鉄骨柱２の周囲を囲むように巻き付けた耐火被覆材３のうち、下地金物１０の固定部１２に対応する部分を取り除くことで、縦ランナー４を固定するために固定部１２を露出させることができる。 (Connecting part 13)
The connecting portion 13 is made of a thin steel material, forms the upper surface of the base metal fitting 10, and has a rectangular shape when viewed from above. When the base metal 10 is engaged with the engaging portion K of the steel frame column 2, the connecting portion 13 is between the base end portion and the fixing portion 12 of the locking portion 11 (in other words, the side surface 2a of the steel frame column 2 and the connecting portion 13). It is a portion that connects the locking portion 11 and the fixing portion 12 so that a space V is formed (between the fixing portions 12). Here, by forming the space V, the fixing portion 12 is separated from the side surface 2a of the steel frame column 2 by the thickness of the space V. That is, the fixing portion 12 is exposed in order to fix the vertical runner 4 by removing the portion of the refractory covering material 3 wound around the steel frame column 2 corresponding to the fixing portion 12 of the base metal fitting 10. be able to.

（立壁部１４及び当接部１５）
立壁部１４（側壁）は、固定部１２の横幅方向の端部から後方に向かうように略垂直に立ち上がった部分である。立壁部１４の立ち上がり量（換言すると、下地金物１０の前後方向の長さｄ）は、耐火被覆材３の厚み（例えば、２０ｍｍ）に対応して設定されている。 (Standing wall portion 14 and contact portion 15)
The vertical wall portion 14 (side wall) is a portion that rises substantially vertically from the end portion of the fixed portion 12 in the lateral width direction toward the rear. The rising amount of the standing wall portion 14 (in other words, the length d in the front-rear direction of the base metal fitting 10) is set corresponding to the thickness of the refractory coating material 3 (for example, 20 mm).

当接部１５は、立壁部１４の後端から略垂直に曲がって下地金物１０の横幅方向外側に向かう方向に屈曲している。当接部１５は、下地金物１０が係合部Ｋに取り付けられたときに、係合部Ｋの両側部において、鉄骨柱２の側面２ａに当接することで、縦ランナー４を固定部１２に固定する際に下地金物１０を後方から前方に向かうように支持する役割を果たす。 The abutting portion 15 is bent substantially vertically from the rear end of the standing wall portion 14 and is bent in a direction toward the outside in the width direction of the base metal 10. When the base metal fitting 10 is attached to the engaging portion K, the contact portion 15 abuts on the side surface 2a of the steel frame column 2 on both side portions of the engaging portion K, so that the vertical runner 4 is attached to the fixing portion 12. When fixing, it plays a role of supporting the base metal 10 from the rear to the front.

本実施形態では、係止部１１、固定部１２、連結部１３、立壁部１４及び当接部１５が一つの鋼板（金属板）を加工することで構成されているため、これらの部分が一部品として一体化している。このため、本実施形態の下地金物１０は、簡素な構造となり、また、より取り扱い易いものとなっている。ただし、これに限定されるものではなく、各部分が、元々は互いに別パーツからなり、下地金物１０を組み立てる際に各パーツを連結して一体化させてもよい。かかる場合、各パーツを構成する鋼板が十分な肉厚を有していればパーツ同士を溶接にて連結してもよい。 In the present embodiment, since the locking portion 11, the fixing portion 12, the connecting portion 13, the standing wall portion 14, and the contact portion 15 are formed by processing one steel plate (metal plate), these portions are one. It is integrated as a part. Therefore, the base metal fitting 10 of the present embodiment has a simple structure and is easier to handle. However, the present invention is not limited to this, and each part may be originally composed of separate parts from each other, and each part may be connected and integrated when assembling the base metal fitting 10. In such a case, the parts may be connected by welding as long as the steel plates constituting the parts have a sufficient wall thickness.

＜界壁１の施工方法＞
以下、上述した下地金物１０を用いて、鉄骨柱２に対して縦ランナー４を固定することを含む、界壁１の施工方法について説明する。本実施形態の界壁１（仕切壁）の施工方法は、鉄骨柱２の係合部Ｋに下地金物１０（ランナー固定部品）の係止部１１を係合することと（ステップＳ１）、鉄骨柱２及び下地金物１０の上から耐火被覆材３を巻き付けることと（ステップＳ２）、耐火被覆材３のうち、下地金物１０の固定部１２に対応する部分を取り除くことで固定部１２を露出させることと（ステップＳ３）、耐火被覆材３から露出した固定部１２に縦ランナー４を固定することと（ステップＳ４）、を含むことを特徴とする。 <Construction method of boundary wall 1>
Hereinafter, a method of constructing the boundary wall 1 including fixing the vertical runner 4 to the steel frame column 2 by using the above-mentioned base metal fitting 10 will be described. The construction method of the boundary wall 1 (partition wall) of the present embodiment is to engage the locking portion 11 of the base metal fitting 10 (runner fixing part) with the engaging portion K of the steel frame column 2 (step S1), and the steel frame. The fixed portion 12 is exposed by wrapping the fireproof coating material 3 over the pillar 2 and the base metal fitting 10 (step S2) and removing the portion of the fireproof coating material 3 corresponding to the fixing portion 12 of the base metal fitting 10. It is characterized by including (step S3) and fixing the vertical runner 4 to the fixing portion 12 exposed from the refractory coating material 3 (step S4).

先ず、下地金物１０を用意し、鉄骨柱２の側面２ａに設けられた係合部Ｋの２つの受容部Ｋａに、下地金物１０の係止部１１の２つの係止片１１ａを上方から近付ける。そして、受容部Ｋａに係止片１１ａを挿入する。このとき、係止片１１ａの屈曲部１１ｂ（突部）が、受容部Ｋａの内壁に当接するため、係止片１１ａが弾性変形する。 First, the base metal 10 is prepared, and the two locking pieces 11a of the locking portion 11 of the base metal 10 are brought close to the two receiving portions Ka of the engaging portions K provided on the side surface 2a of the steel frame column 2 from above. .. Then, the locking piece 11a is inserted into the receiving portion Ka. At this time, since the bent portion 11b (protrusion portion) of the locking piece 11a abuts on the inner wall of the receiving portion Ka, the locking piece 11a is elastically deformed.

連結部１３が受容部Ｋａの上端に当接した状態となるまで、下地金物１０を下方へと移動させることで、係止部１１が受容部Ｋａに係止される。この結果、下地金物１０が鉄骨柱２の側面２ａに取り付けられる（ステップＳ１）。図８乃至図１０は、鉄骨柱２の側面２ａに下地金物１０が取り付けられた状態を示す図であり、図８は正面図、図９は側面図である。図１０は、図８のＢ−Ｂ断面図であり、鉄骨柱２に取り付けられた下地金物１０の固定部１２に縦ランナー４をその底面においてビスＢで固定した状態を示す説明図である（図１０において、耐火被覆材３は、仮想的に示されている）。なお、下地金物１０は、鉄骨柱２の延在方向に沿って一定間隔毎に複数配置された受容部Ｋａに対して、それぞれ取り付けられる（図２）。 By moving the base metal 10 downward until the connecting portion 13 is in contact with the upper end of the receiving portion Ka, the locking portion 11 is locked to the receiving portion Ka. As a result, the base metal fitting 10 is attached to the side surface 2a of the steel frame column 2 (step S1). 8 to 10 are views showing a state in which the base metal fitting 10 is attached to the side surface 2a of the steel frame column 2, FIG. 8 is a front view, and FIG. 9 is a side view. FIG. 10 is a cross-sectional view taken along the line BB of FIG. 8 and is an explanatory view showing a state in which the vertical runner 4 is fixed to the fixing portion 12 of the base metal fitting 10 attached to the steel frame column 2 with screws B on the bottom surface thereof (FIG. 10). In FIG. 10, the fireproof coating material 3 is virtually shown). The base metal fitting 10 is attached to each of a plurality of receiving portions Ka arranged at regular intervals along the extending direction of the steel frame column 2 (FIG. 2).

このとき、図９に示すように、下地金物１０の係止部１１が備える係止片１１ａは、受容部Ｋａと鉄骨柱２の側面２ａの間に挿入された状態で、屈曲部１１ｂ（受容部Ｋａに挿入された状態で鉄骨柱２の側面２ａから離間する方向に突出する突部）が受容部Ｋａの内壁に当接するため、係止片１１ａが連結部１３と接続された基端部を起点として撓むようにして弾性変形する。これにより、受容部Ｋａ内で係止片１１ａが弾性変形する結果、係止部１１が受容部Ｋａに保持されるようになる。このように本実施形態の下地金物１０は、係止部１１を上記の手順にて受容部Ｋａに係止させることにより、ワンタッチで鉄骨柱２の側面２ａに取り付けることが可能である。 At this time, as shown in FIG. 9, the locking piece 11a included in the locking portion 11 of the base metal 10 is inserted between the receiving portion Ka and the side surface 2a of the steel frame column 2 and the bent portion 11b (reception). Since the protrusion) that protrudes in the direction away from the side surface 2a of the steel frame column 2 while being inserted into the portion Ka abuts on the inner wall of the receiving portion Ka, the locking piece 11a is connected to the connecting portion 13. It is elastically deformed so as to bend from the starting point. As a result, the locking piece 11a is elastically deformed in the receiving portion Ka, and as a result, the locking portion 11 is held by the receiving portion Ka. As described above, the base metal fitting 10 of the present embodiment can be attached to the side surface 2a of the steel frame column 2 with one touch by locking the locking portion 11 to the receiving portion Ka by the above procedure.

次に、鉄骨柱２及び下地金物１０の上から耐火被覆材３を巻き付ける（ステップＳ２）。耐火被覆材３は、例えば、耐熱性ロックウールからなるフェルトと可撓性有機質表面材との積層物である。このとき、下地金物１０、特に固定部１２には、鉄骨柱２の側面２ａに押し付けられる方向に荷重がかかるため、下地金物１０に変形（湾曲）が生じてしまう可能性がある。 Next, the refractory coating material 3 is wound over the steel frame column 2 and the base metal fitting 10 (step S2). The refractory coating material 3 is, for example, a laminate of felt made of heat-resistant rock wool and a flexible organic surface material. At this time, since a load is applied to the base metal fitting 10, particularly the fixing portion 12, in the direction of being pressed against the side surface 2a of the steel frame column 2, the base metal fitting 10 may be deformed (curved).

本実施形態に係る下地金物１０では、上述した通り、立壁部１４及び当接部１５が形成されていることで、係合部Ｋの両側部において、当接部１５が鉄骨柱２の側面２ａに当接して下地金物１０を支持する。さらに、連結部１３の後端部も、鉄骨柱２の側面２ａに当接して下地金物１０を支持する。したがって、作業者が、耐火被覆材３を鉄骨柱２及び下地金物１０の上から巻き付ける際に、下地金物１０が湾曲して変形してしまうことが抑制される。つまり、鉄骨柱２の側面２ａから固定部１２の間における空間Ｖの厚みが適切に保持される。 In the base metal fitting 10 according to the present embodiment, as described above, the vertical wall portion 14 and the abutting portion 15 are formed, so that the abutting portion 15 is formed on the side surface 2a of the steel frame column 2 on both side portions of the engaging portion K. Supports the base metal 10 in contact with. Further, the rear end portion of the connecting portion 13 also abuts on the side surface 2a of the steel frame column 2 to support the base metal fitting 10. Therefore, when the operator winds the refractory covering material 3 from above the steel frame column 2 and the base metal fitting 10, the base metal fitting 10 is prevented from being curved and deformed. That is, the thickness of the space V between the side surface 2a of the steel frame column 2 and the fixing portion 12 is appropriately maintained.

次に、鉄骨柱２の周囲を囲むように巻き付けた耐火被覆材３のうち、下地金物１０の固定部１２に対応する部分を取り除き、固定部１２を露出させる（ステップＳ３）。このとき、固定部１２に対応する部分は耐火被覆材３が膨らんでいるため、作業員は目視で固定部１２の大まかな位置を確認した上で、手で耐火被覆材３を軽く押さえることで固定部１２の正確な位置を把握することができる。 Next, of the fireproof coating material 3 wound around the steel frame column 2, the portion corresponding to the fixing portion 12 of the base metal fitting 10 is removed to expose the fixing portion 12 (step S3). At this time, since the fireproof coating material 3 is bulging in the portion corresponding to the fixing portion 12, the worker visually confirms the rough position of the fixing portion 12 and then lightly presses the fireproof coating material 3 by hand. The exact position of the fixed portion 12 can be grasped.

次に、耐火被覆材３から露出した下地金物１０の固定部１２に縦ランナー４を固定する（ステップＳ４）。より詳しく説明すると、下地金物１０の横幅方向において二つの縦ランナー４を縦ランナー４間に隙間Ｓが設けられるように並べ、各々の縦ランナー４をビスＢによって固定部１２に固定する。このとき、図１０に示すように、ガイド部１２ａを挟んで互いに反対の位置に縦ランナー４を固定することで、隣接する二つの縦ランナー４の間に遮音上必要となる隙間Ｓ（例えば、約１０ｍｍ）を容易に確保することが可能となる。また、鉄骨柱２と縦ランナー４の間（換言すると、鉄骨柱２の側面２ａと下地金物１０の固定部１２の間）に耐火被覆材３を配置するための空間Ｖが適切に確保される（図１０）。 Next, the vertical runner 4 is fixed to the fixing portion 12 of the base metal fitting 10 exposed from the refractory coating material 3 (step S4). More specifically, two vertical runners 4 are arranged in the horizontal width direction of the base metal 10 so that a gap S is provided between the vertical runners 4, and each vertical runner 4 is fixed to the fixing portion 12 by a screw B. At this time, as shown in FIG. 10, by fixing the vertical runners 4 at positions opposite to each other with the guide portion 12a in between, a gap S (for example, a gap S required for sound insulation) between two adjacent vertical runners 4 is required. Approximately 10 mm) can be easily secured. Further, a space V for arranging the fireproof coating material 3 is appropriately secured between the steel frame column 2 and the vertical runner 4 (in other words, between the side surface 2a of the steel frame column 2 and the fixing portion 12 of the base metal 10). (Fig. 10).

以上のように、本実施形態のランナー固定部品及び仕切壁の施工方法によれば、ランナー固定部品を現場で容易かつ適切に柱に取り付けることができ、かつ、柱に対してランナーを適切に配置することが可能となる。このとき、本実施形態のランナー固定部品を用いることで、柱の表面とランナーの間に耐火被覆材を配置するための空間Ｖ（クリアランス）を確保することができる。したがって、仕切壁の施工や建物の施工を効率的かつ適切に行うことが可能となる。 As described above, according to the method of constructing the runner fixing parts and the partition wall of the present embodiment, the runner fixing parts can be easily and appropriately attached to the pillars at the site, and the runners are appropriately arranged with respect to the pillars. It becomes possible to do. At this time, by using the runner fixing parts of the present embodiment, it is possible to secure a space V (clearance) for arranging the fireproof coating material between the surface of the column and the runner. Therefore, it is possible to efficiently and appropriately perform the construction of the partition wall and the construction of the building.

そして、本実施形態のランナー固定部品は、現場で柱の係合部に着脱可能に取り付けられるため、事前に柱の側面に所定の間隔を空くようにランナー固定部品としてのプレート部材を溶接した場合のように、柱の運搬工程などにおいて、ランナー固定部品としてのプレート部材が変形してしまうことはない。 Since the runner fixing component of the present embodiment is detachably attached to the engaging portion of the column at the site, when the plate member as the runner fixing component is welded to the side surface of the column in advance so as to leave a predetermined interval. As described above, the plate member as a runner fixing part is not deformed in the column transportation process or the like.

＜変形例＞
以上までに本発明のランナー固定部品及び界壁に関して、その構成及び利用方法についての一実施形態を例に挙げて説明してきたが、上述の実施形態は、あくまでも一例に過ぎず、他の例も考えられる。 <Modification example>
The runner fixing parts and the boundary wall of the present invention have been described above by giving an example of an embodiment of the configuration and usage thereof, but the above-described embodiment is merely an example, and other examples are also included. Conceivable.

以下、図１１を参照して、変形例に係るランナー固定部品である下地金物１０Ｘの構成について説明をする。なお、上述の実施形態に係る下地金物１０と重複する部分は説明を省略し、下地金物１０と異なる部分を中心に説明を行う。図１１は、下地金物１０Ｘの斜視図である。 Hereinafter, the configuration of the base metal fitting 10X, which is the runner fixing component according to the modified example, will be described with reference to FIG. The portion overlapping with the base metal fitting 10 according to the above-described embodiment will be omitted, and the description will be focused on the portion different from the base metal fitting 10. FIG. 11 is a perspective view of the base metal fitting 10X.

図１１に示すように、変形例に係るランナー固定部品である下地金物１０Ｘは、固定部１２に開口１２Ｘｂが形成されており、開口１２Ｘｂから後方へ向かう方向に折り曲げられた連結部１３Ｘが延在している。そして、連結部１３Ｘの後端部から下方に向かって係止部１１Ｘが設けられている。 As shown in FIG. 11, in the base metal fitting 10X which is the runner fixing component according to the modified example, the opening 12Xb is formed in the fixing portion 12, and the connecting portion 13X bent in the rearward direction extends from the opening 12Xb. doing. A locking portion 11X is provided downward from the rear end portion of the connecting portion 13X.

係止部１１Ｘは、２つの係止片１１Ｘａを有している。各係止片１１Ｘａは、図１１に示されるように、下方に向かうにつれて固定部１２Ｘに近づくように突出し、その先端には固定部１２Ｘから離間する方向に屈曲した屈曲部１１Ｘｂが形成されている。また、各係止片１１Ｘａには、その下端から上方に向かう切り欠き１１Ｘｃが形成されている。このような構成により、連結部１３Ｘと接続された基端部を起点として、各係止片１１Ｘａの前端部（屈曲部１１Ｘｂ）が後方に撓むように弾性変形することが可能となっている。 The locking portion 11X has two locking pieces 11Xa. As shown in FIG. 11, each locking piece 11Xa protrudes toward the fixed portion 12X as it goes downward, and a bent portion 11Xb bent in a direction away from the fixed portion 12X is formed at the tip thereof. .. Further, each locking piece 11Xa is formed with a notch 11Xc extending upward from the lower end thereof. With such a configuration, it is possible to elastically deform the front end portion (bending portion 11Xb) of each locking piece 11Xa so as to bend backward, starting from the base end portion connected to the connecting portion 13X.

なお、下地金物１０Ｘは、鋼板（金属板に相当）を打ち抜き加工して、全体の輪郭及び係止部１１Ｘ及び連結部１３Ｘに相当する箇所を形成し、固定部１２と接続されている箇所を起点として連結部１３Ｘを内側に折り返すことで形成される。なお、図１１では、図示を省略したが、固定部１２Ｘの上端の中央部に、下地金物１０のガイド部１２ａと同様のガイド部を設けることも可能である。 In the base metal 10X, a steel plate (corresponding to a metal plate) is punched to form an overall contour and a portion corresponding to the locking portion 11X and the connecting portion 13X, and the portion connected to the fixing portion 12 is formed. It is formed by folding back the connecting portion 13X inward as a starting point. Although not shown in FIG. 11, it is also possible to provide a guide portion similar to the guide portion 12a of the base metal 10 at the central portion of the upper end of the fixing portion 12X.

下地金物１０Ｘの係止片１１Ｘａを鉄骨柱２の係合部Ｋが備える受容部Ｋａに挿入すると、係止片１１Ｘａの後端が鉄骨柱２の側面２ａと当接し、係止片１１Ｘａの屈曲部１１Ｘｂが受容部Ｋａの内壁に当接することで、係止片１１Ｘａが弾性変形する。このようにして、下地金物１０Ｘは鉄骨柱２の側面２ａに対して固定される。 When the locking piece 11Xa of the base metal 10X is inserted into the receiving portion Ka provided in the engaging portion K of the steel frame column 2, the rear end of the locking piece 11Xa comes into contact with the side surface 2a of the steel frame column 2 and the locking piece 11Xa is bent. When the portion 11Xb comes into contact with the inner wall of the receiving portion Ka, the locking piece 11Xa is elastically deformed. In this way, the base metal fitting 10X is fixed to the side surface 2a of the steel frame column 2.
