Description

本発明は、帯板状の筋交いの接合構造及び該接合構造を用いた耐力壁パネルに関する。   The present invention relates to a strip-like bracing joint structure and a load-bearing wall panel using the joint structure.

薄板軽量形鋼製を用いたスチールハウスにおいては、薄板軽量形鋼製の枠材に面材または筋交いを取り付けて耐力壁パネルが構成されている。
このような耐力壁パネルのうち帯板状の筋交いを用いたものにおいて、筋交いの端部における接合は以下のようになされている。
縦枠材と横枠材の接合部となるコーナ部において、その外側面に矩形板状のガセットプレートをタッピンねじにより固着する。そして、ガセットプレートのさらに外面に筋交いの端部を当接して、外側から複数のタッピンねじによって固着する（特許文献１参照）。
特開平９−２７３２４８号公報（図１、図２、図１０、図１４、図１８、図２０） In a steel house using a thin lightweight steel, a bearing wall panel is configured by attaching a face material or a brace to a thin lightweight steel frame material.
In such a load-bearing wall panel using a strip-like brace, joining at the end of the brace is performed as follows.
A rectangular gusset plate is fixed to the outer surface of the corner portion, which is a joint portion between the vertical frame member and the horizontal frame member, with a tapping screw. Then, the end of the braces is brought into contact with the outer surface of the gusset plate, and is fixed by a plurality of tapping screws from the outside (see Patent Document 1).
Japanese Patent Laid-Open No. 9-273248 (FIGS. 1, 2, 10, 14, 18, and 20)

薄板軽量形鋼からなる帯板を筋交いとした耐力壁は、合板等の面材を使用した耐力壁に較べて品質が安定し、白蟻被害もないなどの優位性がある。また、鋼板を表面材に使用した耐力壁に較べては剛性、耐力調整が容易であるという特徴もある。
このように、薄板軽量形鋼からなる帯板を筋交いとして用いることについては種々の優位性および特徴がある。
にもかかわらず、薄板軽量形鋼を筋交いとして用いることが普及してない。
この理由は以下の点にある。 A bearing wall made of thin lightweight steel strips has advantages such as stable quality and no white ant damage compared to bearing walls using face materials such as plywood. In addition, there is a feature that rigidity and proof stress can be easily adjusted as compared with a load bearing wall using a steel plate as a surface material.
As described above, there are various advantages and features regarding the use of a strip made of thin lightweight steel as a brace.
Nevertheless, the use of thin, lightweight sections as braces is not widespread.
The reason is as follows.

上記の特許文献１に示された耐力壁パネルにおいては、枠材の外側面に仕上げ材を貼る。しかし、縦枠材と横枠材の接合されるコーナ部では、枠材の外側面にガセットプレートが取り付けられ、その外側面に筋交いがビス止めされる。筋交いの端部においては、筋交いの端部接合部を介して筋交いの引張力が枠材に伝達するので、引張力に耐えうるだけの接合部の耐力が必要である。そのため、多数のビスを狭い面積の中に打つ必要がある。   In the load-bearing wall panel shown in the above-mentioned Patent Document 1, a finishing material is pasted on the outer surface of the frame material. However, in the corner portion where the vertical frame member and the horizontal frame member are joined, a gusset plate is attached to the outer surface of the frame member, and the braces are screwed to the outer surface. At the end of the brace, the tensile force of the brace is transmitted to the frame member via the end joint of the brace, so that the joint must have enough strength to withstand the tensile force. Therefore, it is necessary to hit a large number of screws in a small area.

このような筋交い端部の接合構造においては、筋交い端部において、枠材の外面よりもビス頭部が、ガセットプレートの厚みと、筋交いの厚み、さらにはビスの頭部厚みを加えた分だけ（５〜６ｍｍ程度）外方へ突出する、いわゆる不陸が生じることになる。
そのため、この外方への突出部が仕上げ材を貼る際に邪魔になり施工性が悪いと共に、外観も悪くなるという問題がある。
この点、突出部の厚み分に相当する板材を枠材に設置して枠材の外面を面一にすることも考えられるが、そのようにするにはかなりの手間がかかる。 In such a bracing end joint structure, the screw head is more than the outer surface of the frame material at the bracing end, plus the thickness of the gusset plate, the bracing thickness, and the screw head thickness. A so-called unevenness that protrudes outward (about 5 to 6 mm) occurs.
Therefore, there is a problem that this outward projecting portion becomes an obstacle when applying the finishing material and the workability is poor and the appearance is also deteriorated.
In this regard, it is conceivable to install a plate material corresponding to the thickness of the protruding portion on the frame material so that the outer surface of the frame material is flush with the frame material, but this requires considerable effort.

上記のような、問題は軽量形鋼の枠材からなるスチールハウスに限られず、例えば軽量鉄骨からなる枠材に帯板からなる筋交いを取り付ける場合にも生ずる。   The problem as described above is not limited to a steel house made of a lightweight steel frame material, and also occurs when a brace made of a strip is attached to a frame material made of a lightweight steel frame, for example.

本発明はかかる課題を解決するためになされたものであり、枠材に帯板からなる筋交いを取り付けるに際して、枠材に仕上げ材を貼る際に邪魔にならないような筋交いの接合構造を得ることを目的としている。
また、上記のような接合構造を備えた耐力壁パネルを得ることを目的としている。 The present invention has been made to solve such a problem, and when a brace made of a strip is attached to a frame material, a bracing joint structure is obtained that does not get in the way when a finishing material is pasted on the frame material. It is aimed.
Moreover, it aims at obtaining the load-bearing wall panel provided with the above joining structures.

（１）本発明に係る筋交いの接合構造は、鋼製の縦材と上下横材により矩形状に構成された枠材に、帯板状の筋交いを、接合部材を介して接合する筋交いの接合構造であって、接合部材は、枠材の内面側に当接して枠材に接合される枠材接合部と、筋交いが接合される筋交い接合部を備えてなり、接合部材を枠材に取り付けた状態において、枠材接合部より筋交い接合部が枠材の内面側になるように形成されており、
前記接合部材は、断面略コ字状に形成された板状部材からなる本体部と、コ字の向かい合う二つの片部の端部から延出する一対の脚片部を有し、該脚片部が横枠材に接合される枠材接合部になっており、コ字の他の片部が縦枠材に接合されており、
接合部材を、枠材接合部を枠材の内面側に当接してタッピンねじ接合することによって枠材に取り付け、枠材に取り付けられた接合部材の筋交い接合部に筋交いを当接させてタッピンねじ接合し、この接合状態において筋交いを接合するタッピンねじの頭部が枠材の外面よりも外方に出っ張らないようにしたことを特徴とするものである。
(1) The brace joining structure according to the present invention is a brace joining in which a strip-like brace is joined via a joining member to a frame material configured in a rectangular shape by steel vertical members and upper and lower horizontal members. The structure has a structure in which the joining member includes a frame material joining portion that abuts on the inner surface side of the frame material and is joined to the frame material, and a brace joining portion that joins the brace, and attaches the joining member to the frame material. In this state, the brace joint is formed so as to be on the inner surface side of the frame material from the frame material joint,
The joining member has a main body portion formed of a plate-like member having a substantially U-shaped cross section, and a pair of leg piece portions extending from the end portions of the two pieces facing the U-shape. The part is a frame material joining part joined to the horizontal frame material, the other piece of the U-shape is joined to the vertical frame material,
The joining member is attached to the frame material by abutting the frame material joining portion to the inner surface side of the frame material and joined to the frame material, and the bracing is brought into contact with the bracing joint portion of the joining member attached to the frame material and the tapping screw. The head of the tapping screw that joins the braces in this joined state is prevented from protruding outward from the outer surface of the frame member.

なお、本明細書において、枠材の内面側とは枠材の厚み方向の中心寄りの側をいい、枠材の外面側とは枠材の厚み方向の中心より離れる側をいう。   In the present specification, the inner surface side of the frame member refers to the side closer to the center in the thickness direction of the frame member, and the outer surface side of the frame member refers to the side away from the center in the thickness direction of the frame member.

（２）また、本発明に係る耐力壁パネルは、矩形枠材に帯板状の筋交いを接合してなる耐力壁パネルであって、矩形枠材と筋交いが、上記（１）に記載の筋交いの接合構造によって接合されていることを特徴とするものである。 (2) Moreover, the load-bearing wall panel according to the present invention is a load-bearing wall panel obtained by joining a strip-like brace to a rectangular frame member, and the brace with the rectangular frame member is a brace described in (1) above. It is characterized by being joined by this joining structure.

本発明においては、帯板状の筋交いを枠材に取り付けた状態において筋交いを接合するタッピンねじの頭部が前記枠材の外面よりも外方に出っ張らないようにしたので、仕上げ材を枠材に接合する際に筋交いを接合するタッピンねじ頭部が邪魔にならず、仕上げ材の施工が円滑に行え、作業性に優れると共に仕上げが美しくできる。   In the present invention, since the head portion of the tapping screw for joining the braces in a state in which the strip-like braces are attached to the frame material is prevented from protruding outward from the outer surface of the frame material, the finishing material is the frame material. The tapping screw head that joins the braces when joining to each other does not get in the way, the finishing material can be applied smoothly, the workability is excellent and the finish can be beautiful.

図１は本発明の一実施形態である筋交いの接合構造を適用した耐力壁パネルの説明図、図２は図１の破線丸で囲んだ部分を拡大して示す拡大図である。図１、図２に基づいて本実施の形態を説明する。
耐力壁パネル１は、薄板軽量形鋼製の横枠材３と、同じく薄板軽量形鋼製の縦枠材５からなる矩形の枠材に、接合部材７を介して筋交い９を接合して構成されている。なお、この例では枠の中央部に間柱８が設置されている。 FIG. 1 is an explanatory view of a load-bearing wall panel to which a bracing joint structure according to an embodiment of the present invention is applied, and FIG. 2 is an enlarged view showing a portion surrounded by a broken-line circle in FIG. The present embodiment will be described with reference to FIGS.
The load-bearing wall panel 1 is configured by joining braces 9 to a rectangular frame material made of a thin frame lightweight section steel horizontal frame member 3 and a thin frame lightweight section steel vertical frame member 5 via a joining member 7. Has been. In this example, a stud 8 is installed at the center of the frame.

横枠材３は薄板軽量形鋼製の溝形鋼からなる。また、縦枠材５は薄板軽量形鋼製のリップ溝形鋼と、薄板軽量形鋼製の角形鋼（以下、「軽角形鋼」という。）からなり、軽角形鋼の片面にリップ溝形鋼の底面を接合して形成されている。
なお、薄板軽量形鋼は厚さ2.3mm未満の鋼板からなる部材をいう。
また、筋交い９は、帯板状の薄板軽量形鋼からなる。 The lateral frame member 3 is made of a grooved steel made of thin lightweight steel. The vertical frame member 5 is composed of a lip groove steel made of a thin lightweight steel and a square steel made of a thin lightweight steel (hereinafter referred to as “light square steel”), and a lip groove is formed on one side of the light square steel. It is formed by joining the bottom surfaces of steel.
The thin lightweight steel is a member made of a steel plate having a thickness of less than 2.3 mm.
Further, the brace 9 is made of a strip-shaped thin lightweight steel.

接合部材７は、図２および図３に示すように、平断面が略Ｌ字状に形成された板状部材からなる本体部と、Ｌ字を構成する片部７ａ、７ｂのうち、一方の片部７ａの端部にクランク状の折曲部７ｃを介して形成された帯板状の脚片部７ｄとを備えてなる。
このような接合部材７においては、図２に示されるように、片部７ａの外面側に筋交い９がタッピンねじ１１によって接合され、この片部７ａが本発明の筋交い接合部となる。また、片部７ｂは縦枠材５にタッピンねじ１３によって接合される。さらに、脚片部７ｄは横枠材３にタッピンねじ１５によって接合され、この脚片部７ｄは本発明の枠材接合部となる。 As shown in FIGS. 2 and 3, the joining member 7 includes a main body portion formed of a plate-like member having a flat cross section formed in a substantially L shape, and one of the pieces 7 a and 7 b constituting the L shape. A strip-like leg piece 7d formed through a crank-like bent part 7c is provided at the end of the piece 7a.
In such a joining member 7, as shown in FIG. 2, the brace 9 is joined to the outer surface side of the piece 7a by a tapping screw 11, and this piece 7a becomes the brace joint of the present invention. The piece 7 b is joined to the vertical frame member 5 by a tapping screw 13. Further, the leg piece portion 7d is joined to the horizontal frame member 3 by a tapping screw 15, and this leg piece portion 7d becomes the frame member joining portion of the present invention.

図４は筋交い９を接合部材７を介して枠材に接合した状態における、片部７ａ位置における平断面図である（横枠材３は図示を省略している）。また、図５は、同じく筋交い９を接合部材７を介して枠材に接合した状態における、脚片部７ｄ位置における平断面図である。
なお、図４および図５においては、枠材を基礎に接合するためのホールダウン金物１７が示されている。 FIG. 4 is a plan cross-sectional view at the position of the piece 7a in a state where the brace 9 is joined to the frame member via the joining member 7 (the horizontal frame member 3 is not shown). FIG. 5 is a cross-sectional plan view of the leg piece portion 7d in a state where the brace 9 is joined to the frame member via the joining member 7 in the same manner.
4 and 5 show a hole-down hardware 17 for joining on the basis of a frame material.

図４に示されるように、接合部材７における片部７ａ（筋交い接合部）は、縦枠材の外側面５ａよりも、筋交い９の厚みＳとタッピンねじ頭厚みＢを加えた長さだけパネル内側に配置されている。そして、この例では片部７ｂの端辺が縦枠材５の内側面５ｂと面一になるように配置されており、その結果、片部７ｂの幅Ｗ１（図３参照）と縦枠材幅Ｌとの関係は下式で示されるようになっている。
筋交い接合部幅Ｗ１＝{縦枠材幅Ｌ−（筋交い９の厚みＳ＋タッピンねじ頭厚みＢ）} As shown in FIG. 4, the piece 7 a (the brace joint) in the joining member 7 is a panel having a length obtained by adding the thickness S of the brace 9 and the tapping screw head thickness B to the outer surface 5 a of the vertical frame member. Arranged inside. And in this example, it arrange | positions so that the edge of the piece part 7b may become flush | planar with the inner surface 5b of the vertical frame material 5, As a result, width W1 (refer FIG. 3) of the piece part 7b, and a vertical frame material The relationship with the width L is shown by the following equation.
Bracing joint width W1 = {Vertical frame member width L- (Thickness 9 of bracing 9 + Tapping screw head thickness B)}

上式で示すように片部７ｂの幅Ｗ１を設定することにより、筋交い９を接合した際に、筋交い９を接合するタッピンねじの頭部と縦枠材５の外側面が面一になる。   By setting the width W1 of the piece 7b as shown in the above equation, when the brace 9 is joined, the head of the tapping screw that joins the brace 9 and the outer surface of the vertical frame member 5 are flush with each other.

なお、片部７ｂの端辺が縦枠材５の内側面５ｂと面一になるように配置することを前提として、片部７ｂの幅Ｗ１を下式で示すように設定すれば、筋交い９を接合した際に、筋交い９を接合するタッピンねじの頭部が縦枠材５の外側面よりも突出しないようになる。
筋交い接合部幅Ｗ１≦{縦枠材幅Ｌ−（筋交い９の厚みＳ＋タッピンねじ頭厚みＢ）} If the width W1 of the piece 7b is set as shown in the following equation on the assumption that the end side of the piece 7b is flush with the inner side surface 5b of the vertical frame member 5, the bracing 9 When joining, the head of the tapping screw that joins the brace 9 does not protrude beyond the outer surface of the vertical frame member 5.
Bracing joint width W1 ≦ {vertical frame material width L− (thickness 9 of bracing 9 + tapping screw head thickness B)}

上記のように片部７ｂの幅Ｗ１を設定すれば、接合部材７を縦枠材５に取り付けるに際して、片部７ｂの端辺を縦枠材５の内側面５ｂと面一になるように配置しさえすれば、筋交い９を接合するタッピンねじの頭部が縦枠材５の外側面よりも突出しないようにできるので、施工性に優れる。   If the width W1 of the piece 7b is set as described above, when the joining member 7 is attached to the vertical frame member 5, the end side of the piece 7b is arranged to be flush with the inner side surface 5b of the vertical frame member 5. As long as this is done, the head of the tapping screw that joins the brace 9 can be prevented from protruding beyond the outer surface of the vertical frame member 5, so that the workability is excellent.

横枠材３における接合部材７との接合部においては、図５に示されるように、横枠材３の外側面に、タッピンねじの頭部が挿入される凹部が例えばバーリング加工によって形成されている。そして、接合部材７における脚片部７ｄは縦枠材の外側面５ａよりも、凹部１９の加工深さＤだけパネル内側に配置されている。
この例では上記の状態で片部７ｂの端辺が縦枠材５の内側面５ｂと面一になるように配置されているので、片部７ｂの端辺から片部７ｄの外面までの距離Ｗ２（図３参照）と縦枠材幅Ｌとは下式に示す関係になっている。
距離Ｗ２＝{縦枠材幅Ｌ−凹部加工深さＤ} As shown in FIG. 5, in the joint portion of the horizontal frame member 3 with the bonding member 7, a recess into which the head of the tapping screw is inserted is formed on the outer surface of the horizontal frame member 3 by, for example, burring. Yes. And the leg piece part 7d in the joining member 7 is arrange | positioned inside the panel by the processing depth D of the recessed part 19 rather than the outer side surface 5a of a vertical frame material.
In this example, since the end of the piece 7b is arranged so as to be flush with the inner surface 5b of the vertical frame member 5 in the above state, the distance from the end of the piece 7b to the outer surface of the piece 7d. W2 (see FIG. 3) and the vertical frame material width L have the relationship shown in the following equation.
Distance W2 = {Vertical frame material width L−Concavity processing depth D}

距離Ｗ２を上記のように設定することにより、縦枠材５に接合部材を取り付けた状態で縦枠材５を横枠材３に挿入した際に、図５に示すように、接合部材７における脚片部７ｄの外面が横枠材３の凹部１９の内側底面と当接する。この状態で横枠材３の外方からタッピンねじ１５をねじ込むことで、タッピンねじの頭部を凹部内に収容した状態で接合部材７を横枠材３に接合できる。よって、タッピンねじの頭部が横枠材３の外側面から突出することがない。   By setting the distance W2 as described above, when the vertical frame member 5 is inserted into the horizontal frame member 3 with the bonding member attached to the vertical frame member 5, as shown in FIG. The outer surface of the leg piece portion 7 d comes into contact with the inner bottom surface of the concave portion 19 of the horizontal frame member 3. By screwing the tapping screw 15 from the outside of the horizontal frame member 3 in this state, the bonding member 7 can be bonded to the horizontal frame member 3 with the head portion of the tapping screw housed in the recess. Therefore, the head of the tapping screw does not protrude from the outer surface of the horizontal frame member 3.

以上のように、本実施の形態においては、枠材に筋交い９を接合する接合部材７を、平断面略Ｌ字状からなり、Ｌ字の一方の片部７ａの端部にクランク状の折曲部７ｃを介して帯板状の脚片部７ｄを形成し、筋交い９を接合した状態において、筋交い９を接合するタッピンねじの頭部が枠材の外面よりも外方に出っ張らないようにしたので、仕上げ材を枠材に設置する際の施工が容易となり、また美しい仕上げとなる。   As described above, in the present embodiment, the joining member 7 that joins the brace 9 to the frame member has a substantially L-shaped cross section, and the crank-shaped fold is formed at the end of one L-shaped piece 7a. In the state where the strip plate-like leg piece portion 7d is formed via the curved portion 7c and the brace 9 is joined, the head of the tapping screw that joins the brace 9 does not protrude beyond the outer surface of the frame member. Therefore, it is easy to install the finishing material on the frame material, and the finish is beautiful.

また、本実施の形態においては、横枠材３における接合部材７との接合部にタッピンねじの頭部が収容される凹部１９を設けたので、横枠材３と接合部材７との接合部においても、タッピンねじの出っ張りがなく、仕上げ材を円滑かつ美しく施工できる。   In the present embodiment, since the concave portion 19 in which the head of the tapping screw is accommodated is provided at the joint portion of the horizontal frame member 3 with the joint member 7, the joint portion between the horizontal frame member 3 and the joint member 7 is provided. However, there is no protrusion of the tapping screw, and the finishing material can be applied smoothly and beautifully.

接合部材７は脚片部７ｄを横枠材３に接合するのみならず片部７ｂを縦枠材に接合することによって枠材に取り付けられている。一般に横枠側のビス本数は縦枠側より少ないので（通常１/３〜１/２程度）横枠材３と脚片部７ｄの接合のためのタッピンねじ１５の数は数本程度で足りる。このため、タッピンねじ１５の出っ張りの影響はさほど大きくないので、凹部１９を設けなくても差し支えない場合もある。   The joining member 7 is attached to the frame material not only by joining the leg piece portion 7d to the horizontal frame material 3 but also joining the piece portion 7b to the vertical frame material. In general, since the number of screws on the side of the horizontal frame is smaller than that of the side of the vertical frame (usually about 1/3 to 1/2), the number of tapping screws 15 for joining the horizontal frame 3 and the leg piece 7d is sufficient. . For this reason, since the influence of the protrusion of the tapping screw 15 is not so great, there may be a case where the concave portion 19 is not provided.

なお、上記の実施の形態においては、筋交い９を耐力壁パネル１の片面に設置する例を示したが、本発明はこれに限られるものではなく、耐力壁パネル１の両面に筋交い９を設置する場合も含む。
筋交い９を耐力壁パネル１の両面に設置する場合に用いる接合部材７の一例を図６に示す。
図６に示す接合部材２１は、断面略コ字状に形成された板状部材からなる本体部と、コ字の向かい合う二つの片部２１ａ、２１ｂにそれぞれクランク状の屈曲部２１ｃ、２１ｄを介して形成された帯板状の脚片部２１ｅ、２１ｆを備えてなる。そして、脚片部２１ｅ、２１ｆが横枠材３に接合される枠材接合部になっており、他の片部２１ｇが縦枠材５に接合される。 In the above embodiment, the bracing 9 is installed on one side of the load-bearing wall panel 1, but the present invention is not limited to this, and the bracing 9 is installed on both sides of the load-bearing wall panel 1. This includes cases where
An example of the joining member 7 used when the bracing 9 is installed on both surfaces of the load-bearing wall panel 1 is shown in FIG.
The joining member 21 shown in FIG. 6 includes a main body portion formed of a plate-like member having a substantially U-shaped cross section, and two pieces 21a and 21b facing each other with a crank-shaped bent portion 21c and 21d. Band-shaped leg pieces 21e and 21f formed in this manner. The leg piece portions 21 e and 21 f are frame material joint portions joined to the horizontal frame material 3, and the other piece portion 21 g is joined to the vertical frame material 5.

上記のような接合部材２１において、片部２１ｇの幅Ｗ３は、下式で示すように設定されている。
片部２１ｇの幅Ｗ３≦{縦枠材幅Ｌ−２（筋交い厚Ｓ＋タッピンねじ頭厚Ｂ）}
また、脚片部２１ｅ、２１ｆの外面間の距離Ｗ４は下式で示すように設定されている。
脚片部２１ｅ、２１ｆの外面間の距離Ｗ４＝{縦枠材幅Ｌ−２（横枠材凹部加工深さ）} In the joining member 21 as described above, the width W3 of the piece portion 21g is set as shown by the following expression.
Width W3 of one part 21g ≦ {vertical frame material width L-2 (barbed thickness S + tapping screw head thickness B)}
The distance W4 between the outer surfaces of the leg pieces 21e and 21f is set as shown by the following equation.
Distance W4 between the outer surfaces of the leg pieces 21e, 21f = {vertical frame member width L-2 (horizontal frame member recess processing depth)}

図６に示す接合部材２１を用いることにより、耐力壁パネル１の両面に筋交い９を施工でき、枠材にねじり力が作用しないようにできる。   By using the joining member 21 shown in FIG. 6, the braces 9 can be constructed on both surfaces of the load-bearing wall panel 1, and the torsional force can be prevented from acting on the frame material.

上記の実施の形態においては、筋交い９を接合部材７、２１の外面側に接合する例を示したが、筋交い９を接合部材７、２１の内面側に接合してもよい。この場合には、接合部材７、２１における筋交い接合部を、上記の実施の形態の場合よりも筋交い９の厚み分だけ外面側に配置できる。   In the above embodiment, the bracing 9 is joined to the outer surface side of the joining members 7 and 21, but the bracing 9 may be joined to the inner surface side of the joining members 7 and 21. In this case, the brace joints in the joining members 7 and 21 can be arranged on the outer surface side by the thickness of the brace 9 compared to the case of the above embodiment.

また、上記の実施の形態の枠材が薄板軽量形鋼製の場合について説明したが、本発明はこれに限られるものではなく、枠材が軽量鉄骨の場合にも適用できる。   Moreover, although the case where the frame material of said embodiment was a thin plate lightweight shape steel was demonstrated, this invention is not restricted to this, It can apply also when a frame material is a lightweight steel frame.
