Description

本発明は外装材施工用の胴縁取付用金具に関するものである。 The present invention relates to a furring strip mounting bracket for exterior material construction.

従来、外壁の改修において、古くなった既存外壁を撤去することなく、既存外壁上に新規胴縁を配し、その新規胴縁上に新規外壁を施工する改修方法いわゆるカバー工法が知られている。(特許文献1)また、このような既存外壁上に新規胴縁を配する際に、あらかじめ胴縁取付用のアタッチメントを既存外壁上に設置し、そのアタッチメントに新規胴縁を取り付ける方法が知られている。(特許文献2) Conventionally, in the repair of the outer wall, a so-called cover method is known, which is a repair method in which a new furring strip is placed on the existing furring strip and a new outer wall is constructed on the new furring strip without removing the old existing outer wall. .. (Patent Document 1) Further, when arranging a new furring strip on such an existing outer wall, a method of installing an attachment for attaching the furring strip on the existing outer wall in advance and attaching the new furring strip to the attachment is known. ing. (Patent Document 2)

特開2001−107535号公報Japanese Unexamined Patent Publication No. 2001-107535 特開2015−67983号公報JP 2015-67983

特許文献1は、既存外壁上に配した胴縁と、胴縁上に固定して既存外壁を覆うように配した新規外壁材から構成され、胴縁を固定する固定具は既存外壁を貫通して既存外壁を支持する下地に打ち込まれている外壁改修構造である。 Patent Document 1 is composed of a furring strip arranged on an existing outer wall and a new outer wall material fixed on the furring strip and arranged so as to cover the existing outer wall, and a fixture for fixing the furring strip penetrates the existing outer wall. It is an outer wall repair structure that is driven into the base that supports the existing outer wall.

しかしながら、このように胴縁を固定具を用いて直接既存外壁を支持する下地に固定する方法では、胴縁を固定する際に、長尺状の胴縁を保持、扱ったりしながら、取り付け位置の調整や、既存外壁の裏側にある下地まで直接胴縁の固定を行わなければならず、取り付け作業が大変であった。 However, in the method of fixing the furring strip directly to the base that directly supports the existing outer wall using a fixture in this way, when fixing the furring strip, the mounting position is held and handled while holding and handling the long furring strip. And the furring strip had to be fixed directly to the base on the back side of the existing outer wall, which made the installation work difficult.

そこで、特許文献2のような、躯体の壁面に胴縁取り付け用のアタッチメントを固定し、そのアタッチメントに金属胴縁を固定する方法がある。 Therefore, there is a method of fixing the attachment for attaching the furring strip to the wall surface of the skeleton and fixing the metal furring strip to the attachment as in Patent Document 2.

この、特許文献2のアタッチメントは、金属製の板材を長手方向の処々において屈曲することで、壁面にアンカーボルトによって固定される基板部と、前記基板部から屈曲されて前記壁面から離間するように延びる内壁部と、前記内壁部と一体をなし、前記内壁部から前記基板部と平行になるように前記長手方向の端側で屈曲されて延びる胴縁を取り付ける支持部と、前記支持部と一体をなし、前記支持部から前記長手方向の端側で屈曲されて前記壁面に近づくように延びる外壁部とを有するアタッチメント、若しくは、これを左右対称状に形成したアタッチメントである。 The attachment of Patent Document 2 is formed by bending a metal plate material in some places in the longitudinal direction so that the substrate portion fixed to the wall surface by anchor bolts and the substrate portion are bent away from the wall surface portion. The extending inner wall portion is integrated with the inner wall portion, and the support portion to which the furring strip extending from the inner wall portion by being bent at the end side in the longitudinal direction so as to be parallel to the substrate portion is attached and integrated with the support portion. An attachment having an outer wall portion that is bent from the support portion on the end side in the longitudinal direction and extends so as to approach the wall surface, or an attachment formed symmetrically.

しかしながら、この特許文献2で開示されているアタッチメントでは、その形状が金属製の板材を長手方向の処々において屈曲しただけの単純な形状であるため、外力に対する強度が足りず、例えば胴縁取り付け時等の強度が不足し、外力によって変形してしまう可能性があった。 However, in the attachment disclosed in Patent Document 2, since the shape is a simple shape in which a metal plate material is simply bent in some places in the longitudinal direction, the strength against an external force is insufficient, for example, when the furring strip is attached. There was a possibility that it would be deformed by an external force due to insufficient strength.

本発明はこのような課題を解決するために、以下の手段を提供している。 The present invention provides the following means for solving such a problem.

本発明の胴縁取付用金具は、略方形状の固定部と、該固定部の左右方向一端部を垂直方向上方に立ち上げた屈曲面と、該屈曲面の端を固定部と略平行になるように折り曲げた施工面と、固定部の上下方向両端部から垂直方向上方に立ち上げた中央受け片とを有し、該中央受け片は施工面の下に延びる受け片延出部を有しており、施工面が施工面裏面側に向かって変形しようとした際に、施工面裏面側と該受け片延出部とが接することを特徴とする。 The furring strip mounting bracket of the present invention has a substantially rectangular fixed portion, a bent surface in which one end in the left-right direction of the fixed portion is raised upward in the vertical direction, and the end of the bent surface is substantially parallel to the fixed portion. It has a construction surface that is bent so as to be, and a central receiving piece that rises vertically upward from both ends in the vertical direction of the fixed portion, and the central receiving piece has a receiving piece extending portion that extends below the construction surface. When the construction surface is to be deformed toward the back surface side of the construction surface, the back surface side of the construction surface and the extending portion of the receiving piece come into contact with each other.

本発明の胴縁取付用金具においては、施工面の両側端部から垂直方向下方に折り曲げた側片が形成されていることが好ましい。 In the furring strip mounting bracket of the present invention, it is preferable that side pieces bent downward in the vertical direction are formed from both side ends of the construction surface.

本発明の胴縁取付用金具においては、施工面が施工面表面側に向かって変形しようとした際に側片と受け片延出部とが接するように形成されていることが好ましい。 In the furring strip mounting bracket of the present invention, it is preferable that the side piece and the receiving piece extending portion are formed so as to be in contact with each other when the construction surface is to be deformed toward the surface side of the construction surface.

本発明の胴縁取付用金具においては、施工面および/または屈曲面が固定部の左右方向で固定部の中心に向かって近づく方向および/または離れる方向に変形しようとした際に側片と受け片延出部とが接するように形成されていることが好ましい。 In the furring strip mounting bracket of the present invention, when the construction surface and / or the bent surface is to be deformed in the left-right direction of the fixed portion toward the center of the fixed portion and / or in the direction away from the fixed portion, the side piece and the receiving portion are received. It is preferable that it is formed so as to be in contact with the one-sided extension portion.

本発明に係る胴縁取付用金具によれば、胴縁を躯体や既存壁に施工する際の施工性が良好になるとともに、外力に対する強度に優れた、外力による変形が起こりにくい胴縁取付用金具が得られる。 According to the furring strip mounting bracket according to the present invention, the furring strip mounting metal fitting has good workability when the furring strip is applied to the skeleton or an existing wall, and has excellent strength against external force and is less likely to be deformed by external force. Metal fittings can be obtained.

以下に図面を用いて、本発明に係る胴縁取付用金具の実施例(実施例1〜3)について説明する。 Hereinafter, examples (Examples 1 to 3) of the furring strip mounting bracket according to the present invention will be described with reference to the drawings.

<実施例1>
図1に示すような実施例1の胴縁取付用金具1は、既存壁面Hまたは躯体Kに固定される略方形状の固定部2と、固定部2の左右方向一端部から垂直方向上方に立ち上げた屈曲面3と、屈曲面3の端を固定部2とほぼ平行になるように折り曲げた施工面4と、固定部2の上下方向両端部から垂直方向上方に立ち上げた中央受け片5とを有し、該中央受け片5は施工面4の下に延びる受け片延出部6を有している。
<Example 1>
The furring strip mounting bracket 1 of the first embodiment as shown in FIG. 1 has a substantially rectangular fixing portion 2 fixed to the existing wall surface H or the skeleton K, and the fixing portion 2 vertically upward from one end in the left-right direction. The raised bent surface 3, the construction surface 4 in which the end of the bent surface 3 is bent so as to be substantially parallel to the fixed portion 2, and the central receiving piece raised vertically upward from both ends in the vertical direction of the fixed portion 2. The central receiving piece 5 has a receiving piece extending portion 6 extending below the construction surface 4.

受け片延出部6の施工面4裏面に面した側には上部受け部7があり、一方施工面4裏面には、固定部2を固定する壁面H又は躯体Kの側に施工面4が変形しようとした際に上部受け部7と接する上部接部8がある。 The upper receiving portion 7 is on the side of the receiving piece extending portion 6 facing the back surface of the construction surface 4, while the construction surface 4 is on the back surface of the construction surface 4 on the side of the wall surface H or the skeleton K for fixing the fixing portion 2. There is an upper contact portion 8 that comes into contact with the upper receiving portion 7 when trying to deform.

また、図1(a)に示すように、施工面4の両側部を、固定部2を固定する壁面H又は躯体Kの側に向けて垂直方向下方に折り曲げて形成した側片9を設けてもよい。 Further, as shown in FIG. 1A, side pieces 9 formed by bending both side portions of the construction surface 4 downward in the vertical direction toward the wall surface H or the skeleton K for fixing the fixing portion 2 are provided. May be good.

固定部2には、胴縁取付用金具1を、既存壁面Hまたは躯体K等に固定するための固定具α(アンカーボルトやビス等)を挿入するための固定孔10が形成されている。 The fixing portion 2 is formed with a fixing hole 10 for inserting a fixing tool α (anchor bolt, screw, etc.) for fixing the furring strip mounting bracket 1 to the existing wall surface H or the skeleton K or the like.

図2に、胴縁取付用金具1に取り付ける胴縁11の例を示す。使用する胴縁11の形状としては、一般的に知られている図2(a)に示すようなハット型形状のものや、図2(b)、図2(c)に示すような形状のものがある。 FIG. 2 shows an example of the furring strip 11 to be attached to the furring strip mounting bracket 1. As the shape of the furring strip 11 to be used, a hat-shaped shape as shown in FIG. 2 (a), which is generally known, or a shape as shown in FIGS. 2 (b) and 2 (c). There is something.

胴縁取付用金具1や胴縁11の材質は、例えば溶融亜鉛-アルミニウム-マグネシウム合金めっき鋼板等の高耐蝕性のめっき鋼板や、ステンレスといった、金属製ものがあるが、特に材質は限定されるものではない。 The material of the furring strip mounting bracket 1 and the furring strip 11 includes, for example, a highly corrosion-resistant plated steel plate such as a hot-dip galvanized iron-aluminum-magnesium alloy plated steel plate and a metal material such as stainless steel, but the material is particularly limited. It's not a thing.

図3に本発明の胴縁取付用金具1の使用例を示す。本発明の胴縁取付用金具1によれば、既存壁面Hまたは躯体Kに固定した胴縁取付用金具1の施工面4を介して胴縁11の取り付けを行うことにより、取り付け位置の調整、既存壁面Hの裏にある躯体Kへの留め付け、万一の場合の固定具の打ち直し、等々を長尺上の胴縁11を扱いながら行う必要がなくなり、施工性が向上する。 FIG. 3 shows an example of using the furring strip mounting bracket 1 of the present invention. According to the furring strip mounting bracket 1 of the present invention, the mounting position can be adjusted by mounting the furring strip 11 via the construction surface 4 of the furring strip mounting bracket 1 fixed to the existing wall surface H or the skeleton K. It is not necessary to fasten to the skeleton K on the back of the existing wall surface H, re-strike the fixture in case of emergency, etc. while handling the long furring strip 11, and the workability is improved.

本発明の胴縁取付用金具1を用いる建物としては、鉄筋コンクリート造、鉄骨造、木造造等の種々の構造がある。また、壁面Hとしては、ALCや窯業系外壁、金属製外壁、モルタル等種々の壁面がある。また、建物は既存のものであっても良いし、新築のものであっても良い。本願の明細書中では鉄骨造の既存ALC外壁上への施工例を主に示している。 Buildings using the furring strip mounting bracket 1 of the present invention include various structures such as a reinforced concrete structure, a steel frame structure, and a wooden structure. Further, as the wall surface H, there are various wall surfaces such as ALC, a ceramic outer wall, a metal outer wall, and mortar. Further, the building may be an existing one or a new one. In the specification of the present application, an example of construction on an existing ALC outer wall of a steel structure is mainly shown.

例えば図4に示すように、胴縁取付用金具1は、梁部において、既存外壁の内装側にある躯体Kに、ロングテクスビス等を用いて取り付けられる。ここに挙げる例では、上階下階の境目でALCパネルの継ぎ目に位置しているL字アングルLへ固定している。 For example, as shown in FIG. 4, the furring strip mounting bracket 1 is attached to the skeleton K on the interior side of the existing outer wall at the beam portion by using a long tex screw or the like. In the example given here, it is fixed to the L-shaped angle L located at the seam of the ALC panel at the boundary between the upper and lower floors.

これを図5のように胴縁取付用金具1を各階の境目に施工し、このように建物上下方向に間隔をあけて施工した胴縁取付用金具1の施工面4に対して胴縁11を施工し、これを建物左右方向に間隔をあけて設置し、この設置した胴縁11を活用して壁材Sを施工していく。 As shown in FIG. 5, the furring strip mounting bracket 1 is installed at the boundary of each floor, and the furring strip 11 is installed on the construction surface 4 of the furring strip mounting bracket 1 which is constructed at intervals in the vertical direction of the building. Is installed, and the wall material S is installed at intervals in the left-right direction of the building, and the wall material S is installed by utilizing the installed furring strip 11.

建物上下方向の各階の中間部においては、既存壁面HにALC用アンカーAとアンカーボルトを用いて胴縁11の留め付けを行ってもよいし、胴縁取付用金具1を用いて留め付けても良い。 In the middle part of each floor in the vertical direction of the building, the furring strip 11 may be fastened to the existing wall surface H using ALC anchor A and anchor bolts, or fastened using the furring strip mounting bracket 1. Is also good.

また、この胴縁取付用金具1を用いた胴縁11の施工は、建物上下方向に限定されるものではなく、建物左右方向に用いても良い。 Further, the construction of the furring strip 11 using the furring strip mounting bracket 1 is not limited to the vertical direction of the building, and may be used in the horizontal direction of the building.

さらに、図6に示すように、例えば建物下部において、より強固な固定を得るために、既存壁面Hではなく躯体K(基礎部等)への固定を行うために、躯体K(基礎部)に別途基礎金具12等を取り付け、該基礎金具12を介して胴縁取付用金具1を躯体Kに施工するといった方法をとることもできる。なお、基礎金具を取り付けるために形成したALC外壁を一部除去して形成した窪みは、ALC補修材にて埋め戻しを行っておくことが好ましい。 Further, as shown in FIG. 6, for example, in the lower part of the building, in order to obtain a stronger fixation, instead of the existing wall surface H, the skeleton K (foundation portion, etc.) is fixed to the skeleton K (foundation portion, etc.). It is also possible to separately attach the foundation metal fitting 12 or the like, and install the furring strip attachment metal fitting 1 on the skeleton K via the foundation metal fitting 12. It is preferable that the recess formed by partially removing the ALC outer wall formed for attaching the foundation metal fitting is backfilled with an ALC repair material.

また図7に示すように、胴縁取付用金具1へ胴縁11の取り付けを行う際の固定具αの打ち込み時には、胴縁取付用金具1の施工面4に屋内側方向への外力Fがかかることになるが、本発明の胴縁取付用金具1によれば、このような場合、特に胴縁取付用金具1と取付壁面Hとの間に隙間が存在するような場合であっても、受け片延出部6の上部受け部7が、施工面4裏面側の上部接部8を受けて支える形となることで、胴縁取付用金具1の外力Fに対する強度が増し、固定具α打ち込み時の力による変形を防ぐことができる。これにより、例えば取付壁面Hに不陸が存在するような場合であっても、胴縁取付用金具1の下にスペーサー13を挿入するような不陸調整を問題なく行うことができる。 Further, as shown in FIG. 7, when the fixture α is driven in when the furring strip 11 is mounted on the furring strip mounting bracket 1, an external force F in the indoor direction is applied to the construction surface 4 of the furring strip mounting bracket 1. However, according to the furring strip mounting bracket 1 of the present invention, even in such a case, especially when there is a gap between the furring strip mounting bracket 1 and the mounting wall surface H. The upper receiving portion 7 of the receiving piece extending portion 6 receives and supports the upper contact portion 8 on the back surface side of the construction surface 4, so that the strength of the furring strip mounting bracket 1 against the external force F is increased and the fixture is fixed. It is possible to prevent deformation due to force during α driving. Thereby, for example, even if there is a non-landing on the mounting wall surface H, the non-landing adjustment such as inserting the spacer 13 under the furring strip mounting metal fitting 1 can be performed without any problem.

また、この胴縁取付用金具1は、各図に示すように、固定部2の左右両側に、屈曲面3と施工面4と中央受け片5とそれらに付随する受け片延出部6と側片9等を形成することで、2本の胴縁11を一つの胴縁取付用金具1に取り付けることが可能となり、図4、図5に示すような、胴縁11を建物の上下方向や左右方向で繋げるように設置する際に、施工性の向上、取り付け手間の軽減、固定具αや金具等の資材使用量の低減が望める。このことは後に記載する実施例2、実施例3においても同様である。 Further, as shown in each figure, the furring strip mounting bracket 1 has a bent surface 3, a construction surface 4, a central receiving piece 5, and a receiving piece extending portion 6 attached thereto, on both left and right sides of the fixing portion 2. By forming the side pieces 9 and the like, it is possible to attach the two furring strips 11 to one furring strip mounting bracket 1, and the furring strips 11 are vertically oriented in the building as shown in FIGS. 4 and 5. When installing so that they can be connected in the left-right direction, it can be expected to improve workability, reduce installation time, and reduce the amount of materials used such as fixture α and metal fittings. This also applies to Examples 2 and 3 described later.

特に、図4に示すような、上下階の境目でALCパネルの継ぎ目に位置しているL字アングルLへ固定するような場合においては、胴縁取付用金具1を介しての固定を行うことで、留めるつけ面積が狭いL字アングルLに対して、無理なく、建物上下方向に1直線的になるように、胴縁11を繋ぐことができ、施工性が向上する。 In particular, in the case of fixing to the L-shaped angle L located at the joint of the ALC panel at the boundary between the upper and lower floors as shown in FIG. 4, the fixing is performed via the furring strip mounting bracket 1. Therefore, the furring strip 11 can be connected so as to be in a straight line in the vertical direction of the building without difficulty for the L-shaped angle L having a narrow fastening area, and the workability is improved.

<実施例2>
図8に示すような実施例2の胴縁取付用金具1は、実施例1と同様に、既存壁面Hまたは躯体Kに固定される略方形状の固定部2と、固定部2の左右方向一端部から垂直方向上方に立ち上げた屈曲面3と、屈曲面3の端を固定部2とほぼ平行になるように折り曲げた施工面4と、施工面4の両側部を固定部2を固定する壁面H又は躯体Kの側に向けて垂直方向下方に折り曲げた側片9と、固定部2の上下方向両端部から垂直方向上方に立ち上げた中央受け片5とを有し、該中央受け片5は施工面4の下に延びる受け片延出部6有している。
<Example 2>
Similar to the first embodiment, the furring strip mounting bracket 1 of the second embodiment as shown in FIG. 8 has a substantially rectangular fixing portion 2 fixed to the existing wall surface H or the skeleton K and the fixing portion 2 in the left-right direction. The bent surface 3 raised vertically upward from one end, the construction surface 4 in which the end of the bent surface 3 is bent so as to be substantially parallel to the fixing portion 2, and the fixing portions 2 are fixed on both sides of the construction surface 4. It has a side piece 9 bent downward in the vertical direction toward the side of the wall surface H or the skeleton K, and a central receiving piece 5 raised vertically upward from both ends in the vertical direction of the fixing portion 2. The piece 5 has a receiving piece extending portion 6 extending below the construction surface 4.

また、実施例1と同様に、受け片延出部6の施工面4裏面に面した側には上部受け部7があり、一方施工面4裏面には、固定部2を固定する壁面H又は躯体Kの側に施工面4が変形しようとした際に該上部受け部7と接する上部接部8がある。 Further, as in the first embodiment, the receiving piece extending portion 6 has an upper receiving portion 7 on the side facing the back surface of the construction surface 4, while the back surface of the construction surface 4 has a wall surface H or a wall surface H for fixing the fixing portion 2. On the side of the skeleton K, there is an upper contact portion 8 that comes into contact with the upper receiving portion 7 when the construction surface 4 is about to be deformed.

さらに、実施例2の受け片延出部6には、施工面4が固定部2を固定する壁面H又は躯体Kの側から離れるような方向へ変形しようとした際に、側片9と接することでその変形を防止する下部受け部14がある。この下部受け部14と接する側片9の部位は下部接部15とする。 Further, the receiving piece extending portion 6 of the second embodiment comes into contact with the side piece 9 when the construction surface 4 is to be deformed in a direction away from the side of the wall surface H or the skeleton K for fixing the fixing portion 2. Therefore, there is a lower receiving portion 14 that prevents the deformation. The portion of the side piece 9 in contact with the lower receiving portion 14 is the lower contact portion 15.

この実施例2の胴縁取付用金具1によれば、胴縁取付用金具1の施工面4が固定部2を固定する壁面H又は躯体Kの側に変形するのを防止できる実施例1の効果に加えて、受け片延出部6と側片9とに垂直方向上下の変形に対して噛み合うような形状を形成したことにより、実施例1の場合と逆側の変形も防ぐことができる。 According to the furring strip mounting bracket 1 of the second embodiment, it is possible to prevent the construction surface 4 of the furring strip mounting bracket 1 from being deformed to the side of the wall surface H or the skeleton K for fixing the fixing portion 2. In addition to the effect, by forming the receiving piece extending portion 6 and the side piece 9 in a shape that meshes with each other in the vertical direction with respect to the vertical deformation, it is possible to prevent the deformation on the opposite side from the case of the first embodiment. ..

例えば、新規壁材S取り付け後においては、新規壁材Sに負圧の風荷重がかかった際に、胴縁取付用金具1の施工面4にも屋外側方向への負圧の外力Fが作用することになるが、受け片延出部6の下部受け部14が、側片9の下部接部15を受けて支える形となることで、胴縁取付用金具1の外力Fに対する強度が増し、胴縁取付用金具1の耐風圧強度が向上することになる。 For example, after the new wall material S is attached, when a negative pressure wind load is applied to the new wall material S, a negative external force F in the outdoor side is also applied to the construction surface 4 of the furring strip mounting bracket 1. However, since the lower receiving portion 14 of the receiving piece extending portion 6 receives and supports the lower contact portion 15 of the side piece 9, the strength of the furring strip mounting bracket 1 against the external force F is increased. In addition, the wind pressure resistance strength of the furring strip mounting bracket 1 is improved.

<実施例3>
図9に示すような実施例3の胴縁取付用金具1は、実施例1実施例2と同様に、既存壁面Hまたは躯体Kに固定される略方形状の固定部2と、固定部2の左右方向一端部から垂直方向上方に立ち上げた屈曲面3と、屈曲面3の端を固定部2とほぼ平行になるように折り曲げた施工面4と、施工面4の両側部を固定部2を固定する壁面H又は躯体Kの側に向けて垂直方向下方に折り曲げた側片9と、固定部2の上下方向両端部から垂直方向上方に立ち上げた中央受け片5とを有し、該中央受け片5は施工面4の下に延びる受け片延出部6を有している。
<Example 3>
Similar to the first embodiment, the furring strip mounting bracket 1 of the third embodiment as shown in FIG. 9 has a substantially rectangular fixing portion 2 fixed to the existing wall surface H or the skeleton K and the fixing portion 2. A bent surface 3 raised vertically upward from one end in the left-right direction, a construction surface 4 in which the end of the bent surface 3 is bent so as to be substantially parallel to the fixing portion 2, and both side portions of the construction surface 4 are fixed portions. It has a side piece 9 bent downward in the vertical direction toward the side of the wall surface H or the skeleton K for fixing 2, and a central receiving piece 5 raised vertically upward from both ends in the vertical direction of the fixing portion 2. The central receiving piece 5 has a receiving piece extending portion 6 extending below the construction surface 4.

また、実施例1実施例2と同様に、受け片延出部6の施工面4裏面に面した側には上部受け部7があり、一方施工面4裏面には、固定部2を固定する壁面H又は躯体Kの側に施工面4が変形しようとした際に該上部受け部7と接する上部接部8がある。 Further, as in the first embodiment and the second embodiment, the receiving piece extending portion 6 has an upper receiving portion 7 on the side facing the back surface of the construction surface 4, while the fixing portion 2 is fixed on the back surface of the construction surface 4. On the side of the wall surface H or the skeleton K, there is an upper contact portion 8 that comes into contact with the upper receiving portion 7 when the construction surface 4 is about to be deformed.

また、実施例2と同様に、実施例3の受け片延出部6には、施工面4が固定部2を固定する壁面H又は躯体Kの側から離れるような方向へ変形しようとした際に、側片9と接することでその変形を抑止する下部受け部14がある。この下部受け部14と接する側片9の部位は下部接部15とする。 Further, similarly to the second embodiment, when the receiving piece extending portion 6 of the third embodiment is deformed in a direction in which the construction surface 4 is separated from the wall surface H or the skeleton K side for fixing the fixing portion 2. There is a lower receiving portion 14 that suppresses its deformation by coming into contact with the side piece 9. The portion of the side piece 9 in contact with the lower receiving portion 14 is the lower contact portion 15.

さらに、実施例3の受け片延出部6には、施工面4および/または屈曲面3が固定部2の中心から離れる方向に変形しようとした際に、側片9と接することでその変形を防止する側部受け部16がある。この側部受け部16と接する側片の部位は側部接部17とする。 Further, when the construction surface 4 and / or the bent surface 3 tries to be deformed in the direction away from the center of the fixing portion 2, the receiving piece extending portion 6 of the third embodiment is deformed by coming into contact with the side piece 9. There is a side receiving portion 16 for preventing the above. The portion of the side piece in contact with the side receiving portion 16 is the side contact portion 17.

この実施例3の胴縁取付用金具1によれば、実施例1、実施例2の変形防止効果に加えて、施工面4および/または屈曲面3が固定部2の中心から離れる方向に変形することも防ぐことができる。つまり、垂直方向上下の変形に対して噛み合うような形状に加えて、左右方向の変形に対しても噛み合うような形状となっている。 According to the furring strip mounting bracket 1 of the third embodiment, in addition to the deformation preventing effect of the first and second embodiments, the construction surface 4 and / or the bent surface 3 is deformed in a direction away from the center of the fixing portion 2. It can also be prevented. That is, in addition to the shape that meshes with the vertical deformation, the shape also meshes with the horizontal deformation.

例えば、胴縁11や新規壁材S取り付け後において、胴縁取付用金具1の施工面4および/または屈曲面3が固定部2左右方向に変形させるような、荷重や地震等による建物の動きによって生じるような外力Fが働いた場合であっても、受け片延出部6の側部受け部16が、側片9の側部接部17を受けて支える形となることで、胴縁取付用金具1の強度が増し、このような外力Fによる胴縁取付用金具1の変形を防止することができる。 For example, after mounting the furring strip 11 or the new wall material S, the movement of the building due to a load, an earthquake, or the like so that the construction surface 4 and / or the bent surface 3 of the furring strip mounting bracket 1 is deformed in the left-right direction of the fixed portion 2. Even when an external force F such as that generated by the above is applied, the side receiving portion 16 of the receiving piece extending portion 6 receives and supports the side contact portion 17 of the side piece 9, so that the furring strip is supported. The strength of the mounting bracket 1 is increased, and it is possible to prevent the furring strip mounting bracket 1 from being deformed by such an external force F.

もちろん、施工面4および/または屈曲面3が固定部2の中心方向に向かって近づくような変形に対しては、図1に示した実施例1(a)や、図8に示した実施例2、図9に示した実施例3であれば、受け片延出部6と側片9とが接することになり、その変形を防ぐことができる。 Of course, with respect to deformation such that the construction surface 4 and / or the bent surface 3 approaches toward the center of the fixed portion 2, Example 1 (a) shown in FIG. 1 and Example 1 shown in FIG. 8 2. In the third embodiment shown in FIG. 9, the receiving piece extending portion 6 and the side piece 9 come into contact with each other, and its deformation can be prevented.

また、図1に示した実施例1(a)や、図8に示した実施例2、図9に示した実施例3のように、施工面4の両側部を固定部2を固定する壁面H又は躯体Kの側に向けて垂直方向下方に折り曲げた側片9があって、その側片9が壁面Hに当接するようなものであれば、固定部2を固定する壁面H又は躯体Kの側に施工面4が変形しようとした際に側片9が壁面Hにあたって支えられることで、その変形を防ぐ効果が得られる。 Further, as in Example 1 (a) shown in FIG. 1, Example 2 shown in FIG. 8, and Example 3 shown in FIG. 9, a wall surface for fixing both side portions of the construction surface 4 to the fixing portion 2. If there is a side piece 9 bent downward in the vertical direction toward the side of H or the skeleton K, and the side piece 9 abuts on the wall surface H, the wall surface H or the skeleton K for fixing the fixing portion 2 When the construction surface 4 is about to be deformed, the side piece 9 is supported by the wall surface H, so that the effect of preventing the deformation can be obtained.
