Description

本発明は、住宅等の建物の内壁部において内壁パネルを建物の軸組みに固定する内壁パネル固定金具に関し、特に、内壁枠の屋外側面を覆って設けられた断熱材を、内壁枠と軸組との間の空間に容易且つ確実に充填することが可能な内壁パネル固定金具に関する。   The present invention relates to an inner wall panel fixing bracket for fixing an inner wall panel to a building frame in an inner wall portion of a building such as a house, and in particular, a heat insulating material provided to cover the outdoor side surface of the inner wall frame is connected to the inner wall frame and the frame assembly. It is related with the inner wall panel fixing metal fitting which can be filled easily and reliably in the space between.

従来、住宅等の建物における内壁部は、所定の間隔毎に設けられた複数の軸組の間に、内壁パネルを順次取り付けることで構成される。この内壁パネルの軸組への取り付けは、内壁パネルの両端部を、固定金具を用いて軸組にそれぞれ固定することにより行うのが一般的である。図13は、従来例に係る内壁部80の構造を示す概略斜視図である(特許文献1参照)。図に示すように、内壁部80は、木材等を枠組みした内壁枠81と該内壁枠81の裏面を覆うようにして設けられた断熱材82とを具備してなる内壁パネル83が、内壁パネル固定金具84によって軸組85に固定されることで構成されている。   Conventionally, an inner wall portion in a building such as a house is configured by sequentially attaching inner wall panels between a plurality of shaft sets provided at predetermined intervals. Generally, the inner wall panel is attached to the shaft assembly by fixing both end portions of the inner wall panel to the shaft assembly using fixing brackets. FIG. 13 is a schematic perspective view showing the structure of the inner wall 80 according to a conventional example (see Patent Document 1). As shown in the figure, the inner wall portion 80 includes an inner wall panel 83 including an inner wall frame 81 framed with wood or the like and a heat insulating material 82 provided so as to cover the back surface of the inner wall frame 81. It is configured by being fixed to the shaft set 85 by a fixing bracket 84.

内壁パネル固定金具84は、軸組85に取り付けるための基部86と、該基部86と螺合するボルト87と、金属プレートの両端部を略90°曲折して曲折部88aを形成したスペーサ88と、を具備するものである。一方、内壁パネル83を構成する断熱材82は、その厚みが前記スペーサ88の長さ寸法より大きいものであり、その両端が内壁枠81の両端と同じ位置となるように内壁枠81の裏面をも覆った状態で取り付けられている。   The inner wall panel fixing bracket 84 includes a base 86 for mounting on the shaft assembly 85, a bolt 87 screwed to the base 86, a spacer 88 formed by bending both ends of the metal plate approximately 90 ° to form a bent portion 88a. Are provided. On the other hand, the heat insulating material 82 constituting the inner wall panel 83 has a thickness larger than the length of the spacer 88, and the back surface of the inner wall frame 81 is placed so that both ends thereof are at the same positions as both ends of the inner wall frame 81. It is attached in a covered state.

内壁パネル83の軸組85への固定に際しては、内壁パネル固定金具84を、その基部86を軸組85に係止させるとともに、スペーサ88の一方の曲折部88aを軸組85に当接させるようにして軸組85に取り付ける。その後、該内壁パネル固定金具84の左右両側方に内壁パネル83をそれぞれ取り付ける。その際、内壁枠81の屋外側面をスペーサ88の他方の曲折部88aに当接させるとともに、断熱材82を内壁枠81と軸組85との間の空間89に押し込むようにして内壁パネル83を取り付ける。その後、ボルト87を、その頭部が内壁パネル83の屋内側面83aに当接するまでねじ込む。これにより、内壁パネル83は、ボルト87の頭部によって屋外側へ押圧されることで軸組85に押し当てられて固定されるものとなっている。   When fixing the inner wall panel 83 to the shaft set 85, the base wall 86 of the inner wall panel fixing bracket 84 is locked to the shaft set 85, and one bent portion 88a of the spacer 88 is brought into contact with the shaft set 85. And attached to the shaft set 85. Thereafter, the inner wall panels 83 are respectively attached to the left and right sides of the inner wall panel fixing bracket 84. At that time, the outer side surface of the inner wall frame 81 is brought into contact with the other bent portion 88a of the spacer 88, and the heat insulating material 82 is pushed into the space 89 between the inner wall frame 81 and the shaft assembly 85 to thereby change the inner wall panel 83. Install. Thereafter, the bolt 87 is screwed in until its head abuts against the indoor side surface 83 a of the inner wall panel 83. Thereby, the inner wall panel 83 is pressed against the shaft set 85 by being pressed to the outdoor side by the head of the bolt 87, and is fixed.

このように、内壁パネル83を、その内壁枠81が軸組85から所定間隔だけ離間するようにして軸組85に固定し、内壁枠81と軸組85との間に断熱材82を介在させることにより、内壁枠81から軸組85への熱伝導が抑制される。これにより、内壁パネル83をその内壁枠81を軸組85に直に当接させて固定する場合と比較して、屋内から屋外への熱損失が低減され、内壁部80の断熱性能を向上させることが可能となっている。   In this way, the inner wall panel 83 is fixed to the shaft set 85 such that the inner wall frame 81 is spaced apart from the shaft set 85 by a predetermined distance, and the heat insulating material 82 is interposed between the inner wall frame 81 and the shaft set 85. Thus, heat conduction from the inner wall frame 81 to the shaft set 85 is suppressed. Thereby, compared with the case where the inner wall panel 83 is fixed by directly contacting the inner wall frame 81 with the shaft set 85, heat loss from the indoor to the outdoor is reduced, and the heat insulating performance of the inner wall 80 is improved. It is possible.

しかし、従来の内壁パネル固定金具84を用いた内壁パネル83の固定構造では、内壁パネル83の取り付けに際し、前記スペーサ88によって内壁枠81と軸組85との間に確保された空間89に、内壁枠81の裏面を覆う断熱材82を充填する必要があり、また、前述のように、断熱材82の厚みは、スペーサ88の長さより十分大きいものである。従って、作業者が、断熱材82を押し込んだり引っ張る等して空間89に充填させなければならず、このような作業は施工能率を低下させ、また、熟練した作業者が必要とされる、という問題がある。   However, in the conventional fixing structure of the inner wall panel 83 using the inner wall panel fixing bracket 84, when the inner wall panel 83 is attached, the inner wall is placed in the space 89 secured between the inner wall frame 81 and the shaft assembly 85 by the spacer 88. It is necessary to fill the heat insulating material 82 covering the back surface of the frame 81, and the thickness of the heat insulating material 82 is sufficiently larger than the length of the spacer 88 as described above. Therefore, an operator has to fill the space 89 by pushing or pulling the heat insulating material 82, and such an operation reduces the work efficiency and requires a skilled worker. There's a problem.

また、従来の内壁パネル固定金具84では、内壁パネル83を、軸組85に取り付けられた内壁パネル固定金具84のスペーサ88に押し当てて固定するため、内壁パネル83の仕上がり状態、例えば、内壁パネル83の垂直性を表す「建ち」や、各内壁パネル83が一直線に並んでいる度合いを表す「通り」は、主として軸組85や内壁パネル固定金具84の寸法精度や取付精度等に依存するものとなっている。従って、内壁部80の施工後に建ちや通りを確認した結果、予め定められた基準値以内に入っていない場合に、この誤差を、簡易な作業で且つ高い精度で修正する手段が必要とされている。   Further, in the conventional inner wall panel fixing bracket 84, the inner wall panel 83 is pressed against and fixed to the spacer 88 of the inner wall panel fixing bracket 84 attached to the shaft assembly 85, so that the finished state of the inner wall panel 83, for example, the inner wall panel The “building” representing the verticality of 83 and the “street” representing the degree to which the inner wall panels 83 are aligned are mainly dependent on the dimensional accuracy and mounting accuracy of the shaft assembly 85 and the inner wall panel fixing bracket 84. It has become. Therefore, as a result of confirming the building and street after the construction of the inner wall portion 80, if it is not within the predetermined reference value, a means for correcting this error with a simple operation and high accuracy is required. Yes.

本発明は、このような問題に鑑みてなされたものであり、内壁パネルの軸組への固定に際し、内壁パネルを構成する内壁枠と軸組との間の空間に、内壁枠の裏面を覆って設けられた断熱材を、容易且つ確実に充填することを可能とする手段を提供する。   The present invention has been made in view of such problems. When the inner wall panel is fixed to the shaft assembly, the back surface of the inner wall frame is covered in the space between the inner wall frame and the shaft assembly constituting the inner wall panel. The means for enabling easy and reliable filling of the heat insulating material provided is provided.

前記断熱内壁パネル3は、図6に示すように、左右一対の縦柱6の間に複数の横桟7が架設されることで矩形に枠組みされた内壁枠8と、該内壁枠8の屋外側面8aを覆うようにして設けられた易変形断熱材(断熱材)9と、内壁枠8の屋内側面8b全体に貼設された防湿シート10と、を具備してなるものであり、本実施例では、内壁枠8を、縦柱6及び横桟7が鋼材からなる鋼製内壁枠として構成している。この縦柱6は、図3に示すように、横断面が矩形である角鋼の一隅部に、横桟7を受けるための横桟受け部6aが突設されるとともに、該横桟受け部6aと対角位置にある隅部に、後述する内壁枠押さえ板20を収容するための段落ち部6bが形成されてなるものである。また、横桟7は、図に詳細は示さないが、鋼板をS字型に曲折してなるものであり、その長手方向両端部が、左右の縦柱の前記各横桟受け部6aにそれぞれ当接させて配置され、ビス等により固定されている。この時、縦柱6の屋内側面と横桟7の屋内側面とが略面一となっており、内壁枠8の屋内側面8aに防湿シート10を貼設しやすく、また、断熱内壁パネル3の屋内側に図示しない石膏ボードを取り付ける作業が行いやすくなっている。   As shown in FIG. 6, the heat insulating inner wall panel 3 includes an inner wall frame 8 that is rectangularly formed by laying a plurality of horizontal rails 7 between a pair of left and right vertical columns 6, and an outside of the inner wall frame 8. This embodiment includes an easily deformable heat insulating material (heat insulating material) 9 provided so as to cover the side surface 8a, and a moisture-proof sheet 10 attached to the entire indoor side surface 8b of the inner wall frame 8. In the example, the inner wall frame 8 is configured as a steel inner wall frame in which the vertical columns 6 and the cross rails 7 are made of steel. As shown in FIG. 3, the vertical column 6 is provided with a horizontal beam receiving portion 6a for receiving the horizontal beam 7 at one corner of a square steel having a rectangular cross section, and the horizontal beam receiving portion 6a. A step-down portion 6b for accommodating an inner wall frame presser plate 20 to be described later is formed in a corner portion at a diagonal position. Further, although not shown in detail in the drawing, the horizontal beam 7 is formed by bending a steel plate into an S shape, and both longitudinal ends thereof are respectively provided on the horizontal beam receiving portions 6a of the left and right vertical columns. They are placed in contact with each other and fixed with screws or the like. At this time, the indoor side surface of the vertical column 6 and the indoor side surface of the horizontal rail 7 are substantially flush with each other, and it is easy to stick the moisture-proof sheet 10 on the indoor side surface 8a of the inner wall frame 8. It is easy to attach a gypsum board (not shown) to the indoor side.

易変形断熱材9は、例えばグラスウール、ロックウール等の繊維状のものであり、押圧を受けることにより容易に変形可能なものである。この易変形断熱材9は、予め、内壁枠8に合わせて適度な大きさに裁断され、繊維が解けたりしないように袋体に詰められている。この易変形断熱材9は、図6に示すように、その大きさが内壁枠8と同程度であって、内壁枠8の屋外側面8aに取り付けた時に、易変形断熱材9の左右両端が内壁枠8の左右両端と同じ位置となり、縦柱6はその屋外側面が易変形断熱材9によって覆われるものとなっている。このように易変形断熱材9を縦柱6の屋外側面をも覆って設けることにより、図4に示すように、断熱内壁パネル3を軸組2に固定した時に、縦柱6と軸組2との間に生じる空間11に易変形断熱材9の端部を充填して、内壁部1の断熱性能を向上させることが可能となっている。また、易変形断熱材9の厚みは、縦柱6と軸組2との間の空間11に隙間なく充填するために、少なくとも、縦柱6と軸組2との離間距離より大きくすることが好ましい。このように構成される易変形断熱材9は、図6に示すように、所定間隔毎にスタッド12を用いて内壁枠8の屋外側面8aに固定されている。   The easily deformable heat insulating material 9 is a fibrous material such as glass wool or rock wool, and can be easily deformed by being pressed. The easily deformable heat insulating material 9 is cut into an appropriate size in advance according to the inner wall frame 8 and packed in a bag so that the fibers do not unravel. As shown in FIG. 6, the easily deformable heat insulating material 9 is approximately the same size as the inner wall frame 8, and the left and right ends of the easily deformable heat insulating material 9 are attached to the outdoor side surface 8 a of the inner wall frame 8. It becomes the same position as the right and left ends of the inner wall frame 8, and the vertical column 6 is covered with an easily deformable heat insulating material 9 on its outdoor side surface. By providing the easily deformable heat insulating material 9 so as to cover the outdoor side surface of the vertical column 6 as described above, when the heat insulating inner wall panel 3 is fixed to the shaft set 2 as shown in FIG. It is possible to improve the heat insulating performance of the inner wall portion 1 by filling the end portion of the easily deformable heat insulating material 9 into the space 11 formed between the inner wall portion 1 and the inner wall portion 1. In addition, the thickness of the easily deformable heat insulating material 9 is at least larger than the separation distance between the vertical column 6 and the shaft set 2 in order to fill the space 11 between the vertical column 6 and the shaft set 2 without a gap. preferable. As shown in FIG. 6, the easily deformable heat insulating material 9 configured in this way is fixed to the outdoor side surface 8 a of the inner wall frame 8 using studs 12 at predetermined intervals.

図7及び図8は、前記内壁パネル固定金具4の概略構成を示す図であり、図7は斜視図、図8は分解斜視図である。図7及び図8に示すように、内壁パネル固定金具4は、前記軸組2の屋内側面に沿わせるようにして配置される基板13と、該基板13の裏面側に突出して設けられ軸組2の屋外側面に係止される係止部材14と、内壁枠裏当て板15にパイプ部材16が嵌挿固定されてなり断熱内壁パネル3の固定位置を決定するスペーサ17と、パイプ部材16における内壁枠裏当て板15の裏面から突出した部分に外嵌して設けられ、一端が基板13の表面に他端が内壁枠裏当て板15に固着されたコイルスプリング18と、スペーサ17のパイプ部材16内に挿通されて基板13の表面側から螺合された固定ボルト19と、該固定ボルト19の頭部近傍に装着される内壁枠押さえ板20とを、具備してなるものである。尚、本発明において、基板13及び内壁枠裏当て板15の表面・裏面とは、内壁パネル固定金具4を軸組2に取り付けた際の屋内側面・屋外側面を意味している。   7 and 8 are diagrams showing a schematic configuration of the inner wall panel fixing metal fitting 4. FIG. 7 is a perspective view, and FIG. 8 is an exploded perspective view. As shown in FIGS. 7 and 8, the inner wall panel fixing bracket 4 includes a base plate 13 disposed so as to be along the indoor side surface of the shaft set 2, and a shaft set provided so as to protrude from the back side of the base plate 13. 2, a locking member 14 that is locked to the outdoor side surface, a spacer 17 in which the pipe member 16 is fitted and fixed to the inner wall frame backing plate 15, and determines the fixing position of the heat insulating inner wall panel 3. A coil spring 18 that is externally fitted to a portion protruding from the back surface of the inner wall frame backing plate 15, one end fixed to the surface of the substrate 13 and the other end fixed to the inner wall frame backing plate 15, and a pipe member of the spacer 17 A fixing bolt 19 that is inserted into 16 and screwed from the surface side of the substrate 13 and an inner wall frame pressing plate 20 that is mounted near the head of the fixing bolt 19 are provided. In the present invention, the front and back surfaces of the substrate 13 and the inner wall frame backing plate 15 mean the indoor side surface and the outdoor side surface when the inner wall panel fixing bracket 4 is attached to the shaft assembly 2.

基板13は、図7及び図8に示すように、略矩形の鋼板の上下両端部を裏面側に略90°曲折して曲折部13aを形成したものである。この上下の各曲折部13aの幅方向中央部には、嵌合突片13bがそれぞれ突設され、該嵌合突片13bは、図1に示すように、隣接する軸組2の隙間21に嵌合する形状となっている。これにより、内壁パネル固定金具4を軸組2に取り付ける際に、嵌合突片13bを軸組2の隙間21に嵌合させるようにして基板13を配置することで、内壁パネル固定金具4の水平方向への位置ズレを防止することが可能となっている。また、図8に示すように、基板13の幅方向中央部には、前記係止部材14を挿通させるための挿通孔13cが、その鉛直下方には、前記固定ボルト19を螺合させるためのネジ孔13dがそれぞれ形成されている。   As shown in FIGS. 7 and 8, the substrate 13 is formed by bending the upper and lower ends of a substantially rectangular steel plate approximately 90 ° on the back surface side to form a bent portion 13 a. At the center in the width direction of each of the upper and lower bent portions 13a, a fitting protrusion 13b is provided so as to protrude into the gap 21 between the adjacent shaft sets 2 as shown in FIG. It has a shape to fit. Thus, when the inner wall panel fixing bracket 4 is attached to the shaft assembly 2, the board 13 is arranged so that the fitting protrusion 13 b is fitted in the gap 21 of the shaft assembly 2. It is possible to prevent displacement in the horizontal direction. Further, as shown in FIG. 8, an insertion hole 13 c for inserting the locking member 14 is provided in the central portion in the width direction of the substrate 13, and the fixing bolt 19 is screwed in the vertical lower part thereof. Screw holes 13d are respectively formed.

係止部材14は、図8に示すように、鋼製の丸棒の一端部にネジ部14aが、他端部に幅広な拡幅部14bが設けられてなるものである。この係止部材14は、丸棒部分とネジ部14aの外径が軸組2の隙間21の幅より小さくなるように、且つ、拡幅部14bが、平面視では前記隙間21の幅より幅広であって、側面視では前記隙間21の幅より幅狭となるように形成されている。これにより、係止部材14は、拡幅部14bを縦向きにした場合には前記隙間21を通過することができ、拡幅部14bを横向きにした場合には前記隙間21を通過できないものとなっている。また、係止部材14の長さは前記隙間21の奥行きより若干長くなっている。このように構成される係止部材14が、図7及び図8に示すように、基板13の裏面側から挿通孔13cに挿通され、基板13の表面側に突出したネジ部14aにナット22が螺合されることにより、基板13に固定されている。   As shown in FIG. 8, the locking member 14 is formed by providing a threaded portion 14 a at one end of a steel round bar and a widened portion 14 b at the other end. The locking member 14 has an outer diameter of the round bar portion and the screw portion 14a smaller than the width of the gap 21 of the shaft assembly 2, and the widened portion 14b is wider than the width of the gap 21 in plan view. Thus, it is formed so as to be narrower than the width of the gap 21 in a side view. Accordingly, the locking member 14 can pass through the gap 21 when the widened portion 14b is in the vertical direction, and cannot pass through the gap 21 when the widened portion 14b is in the horizontal direction. Yes. Further, the length of the locking member 14 is slightly longer than the depth of the gap 21. As shown in FIGS. 7 and 8, the locking member 14 configured as described above is inserted into the insertion hole 13 c from the back surface side of the substrate 13, and the nut 22 is provided on the screw portion 14 a protruding to the front surface side of the substrate 13. By being screwed together, it is fixed to the substrate 13.

スペーサ17は、断熱内壁パネル3を軸組2から所定距離だけ離間させるためのものであり、図8に示すように、断熱内壁パネル3を屋外側から支持する内壁枠裏当て板15と、断熱内壁パネル3と軸組2との間に所定距離を確保するためのパイプ部材16とを具備してなるものである。内壁枠裏当て板15は、矩形の鋼板の左右両端部が略90°曲折され、その幅方向中央部にパイプ部材16を嵌挿させるための嵌挿穴15aが形成されたものである。この内壁枠裏当て板15は、図3に示すように、その左右両端部が、内壁パネル固定金具4の左右両側方に建て込まれる各断熱内壁パネル3に対し、その内壁枠8を構成する縦柱6の屋外側面にそれぞれ当接することによって屋外側から支持するものである。従って、内壁枠裏当て板15の横幅は、左右の縦柱6を確実に支持できるよう、縦柱6の横幅、左右の断熱内壁パネル3間に設ける目地23の幅等を考慮して決められている。   The spacer 17 is for separating the heat insulating inner wall panel 3 from the shaft assembly 2 by a predetermined distance. As shown in FIG. 8, the spacer 17 supports the inner wall frame backing plate 15 that supports the heat insulating inner wall panel 3 from the outdoor side, and heat insulation. A pipe member 16 for securing a predetermined distance between the inner wall panel 3 and the shaft assembly 2 is provided. The inner wall frame backing plate 15 is formed by bending both left and right end portions of a rectangular steel plate by approximately 90 °, and forming a fitting insertion hole 15a for fitting the pipe member 16 into the center portion in the width direction. As shown in FIG. 3, the left and right ends of the inner wall frame backing plate 15 constitute an inner wall frame 8 for each heat insulating inner wall panel 3 built on both the left and right sides of the inner wall panel fixing bracket 4. The vertical pillar 6 is supported from the outdoor side by abutting on the outdoor side surface. Accordingly, the width of the inner wall frame backing plate 15 is determined in consideration of the width of the vertical column 6 and the width of the joint 23 provided between the left and right heat insulating inner wall panels 3 so that the left and right vertical columns 6 can be reliably supported. ing.

パイプ部材16は、図8に示すように、断面形状が略矩形である角形鋼管であって、その太さは前記固定ボルト19を挿通し得る程度である。このパイプ部材16は、内壁枠裏当て板15の前記嵌挿穴15aに、内壁枠裏当て板15に直交するように嵌挿されて溶接等により固着されている。このパイプ部材16の屋外側端部16aが、図5に示すように、基板13の表面に当接することにより、内壁枠裏当て板15によって屋外側から支持された断熱内壁パネル3は、それ以上屋外側へは移動することができず、断熱内壁パネル3と軸組2との間に所定距離が確保されるものとなっている。この時、断熱内壁パネル3の軸組2からの離間距離は、パイプ部材16のうち内壁枠裏当て板15の裏面から突出した部分(以下、「裏面側突出部」という)16bの長さによって決定される。一方、パイプ部材16のうち内壁枠裏当て板15の表面から突出した部分(以下、「表面側突出部」という)16cの長さは、図4に示すように、内壁枠裏当て板15が縦柱6の屋外側面に当接した状態において、パイプ部材16の屋内側端部16dが縦柱6の段落ち部6bより屋内側に突出しない程度としている。これにより、段落ち部6bに前記内壁枠押さえ板20を配設する際に、パイプ部材16の屋内側端部16dが内壁枠押さえ板20に干渉しないようになっている。尚、本実施例ではパイプ部材16として角形鋼管を用いているが、これに限られず、例えば断面円形の丸形鋼管その他を用いることも可能である。   As shown in FIG. 8, the pipe member 16 is a square steel pipe having a substantially rectangular cross-sectional shape, and the thickness thereof is such that the fixing bolt 19 can be inserted. The pipe member 16 is inserted into the insertion hole 15a of the inner wall frame backing plate 15 so as to be orthogonal to the inner wall frame backing plate 15, and is fixed by welding or the like. As shown in FIG. 5, the heat insulating inner wall panel 3 supported from the outdoor side by the inner wall frame backing plate 15 by the outdoor side end portion 16 a of the pipe member 16 being in contact with the surface of the substrate 13 is further increased. It cannot move to the outdoor side, and a predetermined distance is secured between the heat insulating inner wall panel 3 and the shaft assembly 2. At this time, the separation distance from the shaft assembly 2 of the heat insulating inner wall panel 3 depends on the length of a portion (hereinafter referred to as “back surface side protruding portion”) 16 b of the pipe member 16 protruding from the back surface of the inner wall frame backing plate 15. It is determined. On the other hand, the length of the portion 16c of the pipe member 16 that protrudes from the surface of the inner wall frame backing plate 15 (hereinafter referred to as the “surface-side protruding portion”) is such that the inner wall frame backing plate 15 is as shown in FIG. In a state in which the vertical column 6 is in contact with the outdoor side surface, the indoor side end portion 16 d of the pipe member 16 does not protrude from the stepped portion 6 b of the vertical column 6 to the indoor side. Accordingly, when the inner wall frame pressing plate 20 is disposed in the stepped portion 6b, the indoor side end portion 16d of the pipe member 16 does not interfere with the inner wall frame pressing plate 20. In this embodiment, a square steel pipe is used as the pipe member 16, but the present invention is not limited to this. For example, a round steel pipe having a circular cross section or the like can also be used.

コイルスプリング18は、前記内壁枠裏当て板15を前記基板13と反対方向へ付勢するためのものである。このコイルスプリング18は、図7及び図8に示すように、前記パイプ部材16の裏面側突出部16bに外嵌して設けられ、一端が基板13の表面に他端が内壁枠裏当て板15の裏面にそれぞれ当接している。コイルスプリング18の長さは、図2に示すように、外力が負荷されない状態における初期長さL1が、パイプ部材16の裏面側突出部16bの長さの略2倍程度であって、且つ、図5に示すように、圧縮力が負荷されて最も縮んだ状態における長さL2が、パイプ部材16の裏面側突出部16bの長さと略等しいか若干小さくなっている。これにより、スペーサ17は、外力が負荷されない場合には、内壁枠裏当て板15が基板13からコイルスプリング18の初期長さL1分だけ離間した状態となっており、屋外側への外力が負荷された場合には、コイルスプリング18の存在にかかわらず、パイプ部材16の屋外側端部16aが基板13の表面に当接するまで移動可能となっている。また、コイルスプリング18は、スペーサ17の屋外側への移動の妨げとならない程度の付勢力を有していることが好ましい。   The coil spring 18 is for urging the inner wall frame backing plate 15 in the direction opposite to the substrate 13. As shown in FIGS. 7 and 8, the coil spring 18 is provided by being fitted on the rear surface side protruding portion 16 b of the pipe member 16, one end on the surface of the substrate 13 and the other end on the inner wall frame backing plate 15. Each of them is in contact with the back surface. As shown in FIG. 2, the length of the coil spring 18 is such that the initial length L1 in the state where no external force is applied is approximately twice the length of the rear surface side protruding portion 16b of the pipe member 16, and As shown in FIG. 5, the length L <b> 2 in the most contracted state when the compression force is applied is substantially equal to or slightly smaller than the length of the rear surface side protruding portion 16 b of the pipe member 16. As a result, the spacer 17 is in a state where the inner wall frame backing plate 15 is separated from the substrate 13 by the initial length L1 of the coil spring 18 when no external force is applied. In this case, regardless of the presence of the coil spring 18, the outdoor side end 16 a of the pipe member 16 can move until it abuts against the surface of the substrate 13. Moreover, it is preferable that the coil spring 18 has an urging force that does not hinder the movement of the spacer 17 to the outdoor side.

固定ボルト19は、前記内壁枠押さえ板20を介して断熱内壁パネル3を屋外側へ押圧して所定位置で固定するものである。この固定ボルト19は、図8に示すように、頭部19aと長尺な軸部19bとを有し、軸部19bの全長に渡ってネジが形成され、頭部19aにプラスドライバPDを差し込むための十字型の溝19cが形成されている。ここで、頭部19aは、図3に示すように、パイプ部材16の開口部より若干大きく、相隣接する断熱内壁パネル3間に設けられた目地23の幅より若干小さいものである。また、軸部19bは、図2に示すように、その外径が軸組2の隙間21の幅より小さく、且つ、その長さがコイルスプリング18の前記初期長さL1と前記パイプ部材16の表面側突出部16cの長さとを合わせた長さよりも十分大きくなっている。このような固定ボルト19の軸部19bが、図7及び図8に示すように、パイプ部材16内に挿通され、その先端部が基板13の表面側から前記ネジ孔13dに螺合されている。この時、固定ボルト19は、軸部19bの根元部分に前記内壁枠押さえ板20を装着できるよう、頭部19aがパイプ部材16の開口部と当接する手前までしかねじ込まれず、軸部19bの根元部分が若干露呈された状態となっている。また、図2に示すように、基板13の裏面から突出した軸部19bの先端部は、前述のように軸部19bの外径が軸組2の隙間21の幅より小さいため、該隙間21の奥へと挿入されるものとなっている。   The fixing bolt 19 presses the heat insulating inner wall panel 3 to the outdoor side via the inner wall frame pressing plate 20 and fixes it at a predetermined position. As shown in FIG. 8, the fixing bolt 19 has a head portion 19a and a long shaft portion 19b. A screw is formed over the entire length of the shaft portion 19b, and a plus driver PD is inserted into the head portion 19a. For this purpose, a cross-shaped groove 19c is formed. Here, as shown in FIG. 3, the head portion 19 a is slightly larger than the opening of the pipe member 16 and slightly smaller than the width of the joint 23 provided between the adjacent heat insulating inner wall panels 3. Further, as shown in FIG. 2, the shaft portion 19 b has an outer diameter smaller than the width of the gap 21 of the shaft set 2, and its length is equal to the initial length L1 of the coil spring 18 and the pipe member 16. It is sufficiently larger than the total length of the surface side protruding portion 16c. As shown in FIGS. 7 and 8, the shaft portion 19 b of the fixing bolt 19 is inserted into the pipe member 16, and the tip portion thereof is screwed into the screw hole 13 d from the surface side of the substrate 13. . At this time, the fixing bolt 19 can only be screwed in until the head 19a comes into contact with the opening of the pipe member 16 so that the inner wall frame pressing plate 20 can be attached to the base of the shaft 19b. The portion is slightly exposed. Further, as shown in FIG. 2, the tip end portion of the shaft portion 19b protruding from the back surface of the substrate 13 has the outer diameter of the shaft portion 19b smaller than the width of the gap 21 of the shaft assembly 2 as described above. It is to be inserted into the back of the.

内壁枠押さえ板20は、固定ボルト19の頭部19aと縦柱6の間に介在され、固定ボルト19の頭部19aから受けた押圧力を縦柱6に伝えることで、断熱内壁パネル3を屋外側へ押圧するものである。この内壁枠押さえ板20は、図7及び図8に示すように、矩形の鋼板の上下両端部を曲折してコの字型に形成したものであり、縦柱6を押圧する押圧面20aと、該押圧面20aと略直交する上曲折面20b及び下曲折面20cとを有している。ここで、上曲折面20b及び下曲折面20cの折り曲げ幅は、縦柱6に形成された前記段落ち部6bの段差より若干小さく、内壁枠押さえ板20全体を段落ち部6bの内部に収容できるようになっている。また、内壁枠押さえ板20の幅方向中央部には、図8に示すように、固定ボルト19の軸部19bの根元部分に装着するための切欠き20dが形成されている。この切欠き20dは、下曲折面20cから押圧面20aの高さ方向中央部に渡って形成され、その最上部は固定ボルト19の軸部19bの形状に合わせて円弧状となっている。該切欠き20dの横幅は、固定ボルト19の軸部19bの外径と略等しくなっており、該切欠き20dを軸部19bの根元部分に嵌合させるようにして、軸部19bの上方から内壁枠押さえ板20を落とし込むことにより、内壁枠押さえ板20を固定ボルト19に挿着することが可能となっている。また、押圧面20aにおける切欠き20dの左右両側にはビス孔20eがそれぞれ形成されており、内壁枠押さえ板20を縦柱6の段落ち部6bにビス固定するものとなっている。尚、本発明では、前述のように、固定ボルト19の頭部19aが、相隣接する断熱内壁パネル3間の目地23の幅より小さいため、固定ボルト19の頭部と縦柱6の間に内壁枠押さえ板20を介在させているが、固定ボルト19の頭部19aを目地23の幅より大きくして、頭部19aを直接縦柱6に当接させることにより、固定ボルト19の締結力を断熱内壁パネル3に伝えることも可能である。しかし、本発明のように内壁枠押さえ板20を用いて縦柱6との接触面積を大きくした方が、固定ボルト19の締結力をより確実に断熱内壁パネル3に伝えることができる。   The inner wall frame pressing plate 20 is interposed between the head 19 a of the fixing bolt 19 and the vertical column 6, and transmits the pressing force received from the head 19 a of the fixing bolt 19 to the vertical column 6. It pushes to the outdoor side. As shown in FIGS. 7 and 8, the inner wall frame pressing plate 20 is formed by bending the upper and lower ends of a rectangular steel plate into a U-shape, and a pressing surface 20 a that presses the vertical column 6. The upper bent surface 20b and the lower bent surface 20c are substantially orthogonal to the pressing surface 20a. Here, the bending width of the upper bent surface 20b and the lower bent surface 20c is slightly smaller than the step of the stepped portion 6b formed in the vertical column 6, and the entire inner wall frame pressing plate 20 is accommodated in the stepped portion 6b. It can be done. Further, as shown in FIG. 8, a notch 20 d for mounting on the base portion of the shaft portion 19 b of the fixing bolt 19 is formed in the center portion in the width direction of the inner wall frame pressing plate 20. The notch 20d is formed from the lower bent surface 20c to the center in the height direction of the pressing surface 20a, and the uppermost portion has an arc shape in accordance with the shape of the shaft portion 19b of the fixing bolt 19. The lateral width of the notch 20d is substantially equal to the outer diameter of the shaft portion 19b of the fixing bolt 19. From the upper portion of the shaft portion 19b, the notch 20d is fitted to the root portion of the shaft portion 19b. By dropping the inner wall frame pressing plate 20, the inner wall frame pressing plate 20 can be inserted into the fixing bolt 19. Further, screw holes 20e are formed on both the left and right sides of the notch 20d in the pressing surface 20a, and the inner wall frame pressing plate 20 is fixed to the stepped portion 6b of the vertical column 6 with screws. In the present invention, as described above, the head 19a of the fixing bolt 19 is smaller than the width of the joint 23 between the heat insulating inner wall panels 3 adjacent to each other. Although the inner wall frame holding plate 20 is interposed, the fastening force of the fixing bolt 19 is increased by making the head portion 19a of the fixing bolt 19 larger than the width of the joint 23 and bringing the head portion 19a directly into contact with the vertical column 6. Can be transmitted to the heat insulating inner wall panel 3. However, the fastening force of the fixing bolt 19 can be more reliably transmitted to the heat insulating inner wall panel 3 by increasing the contact area with the vertical column 6 using the inner wall frame pressing plate 20 as in the present invention.

以下、本実施例に係る内壁部1の施工手順について説明する。まず、内壁枠押さえ板20が装着されていない状態の内壁パネル固定金具4を軸組2に取り付ける。すなわち、図9に示すように、内壁パネル固定金具4の係止部材14を、拡幅部14bを縦向きにして軸組2の隙間21へ挿入し、拡幅部14bが軸組2の屋外側へ突出するまで挿通させた後、係止部材14を90°回転させて屋内側へと引き寄せる。これにより、図1に示すように、拡幅部14bが軸組2の屋外側面に係止される。この状態において、図10に示すように、基板13を上下の各嵌合突片13bが隙間21にそれぞれ嵌合するようにして軸組2に押し当て、ナット22を締め付ける。これにより、内壁パネル固定金具4が軸組2に固定される。更に、図に詳細は示していないが、これと同様にして、軸組2に沿って所定間隔ごとに複数の内壁パネル固定金具4を順次取り付ける。   Hereinafter, the construction procedure of the inner wall 1 according to the present embodiment will be described. First, the inner wall panel fixing metal fitting 4 in a state where the inner wall frame pressing plate 20 is not attached is attached to the shaft assembly 2. That is, as shown in FIG. 9, the locking member 14 of the inner wall panel fixing bracket 4 is inserted into the gap 21 of the shaft assembly 2 with the widened portion 14 b oriented vertically, and the widened portion 14 b extends to the outdoor side of the shaft assembly 2. After inserting until it protrudes, the locking member 14 is rotated 90 degrees and pulled toward the indoor side. Thereby, as shown in FIG. 1, the widened portion 14 b is locked to the outdoor side surface of the shaft assembly 2. In this state, as shown in FIG. 10, the substrate 13 is pressed against the shaft assembly 2 so that the upper and lower fitting protrusions 13 b are fitted in the gaps 21, and the nut 22 is tightened. As a result, the inner wall panel fixing bracket 4 is fixed to the shaft assembly 2. Further, although not shown in detail in the drawing, a plurality of inner wall panel fixing brackets 4 are sequentially attached at predetermined intervals along the shaft set 2 in the same manner.

次に、断熱内壁パネル3の建て込みを行う。すなわち、図10に示すように、軸組2に固定した内壁パネル固定金具4の左右両側から、断熱内壁パネル3を、その縦柱6の屋外側面に内壁枠裏当て板15を沿わせ、且つ、隣接する断熱内壁パネル3間に所定幅の目地23を設けるようにしてそれぞれ配置する。ここで、前述のように、易変形断熱材9はスタッド12により縦柱6に固定されているので、スタッド12のない箇所を掴んで縦柱6から引き離すことにより、図10に示すように、易変形断熱材9と縦柱6の間に若干の隙間24を開けることが可能となっている。この隙間24に、内壁枠裏当て板15の一端部を差し込むことにより、内壁枠裏当て板15を縦柱6の屋外側面に沿わせることができる。また、この時、図3に示すように、易変形断熱材9を内壁パネル固定金具4側に押し込んでおく。内壁枠裏当て板15と基板13との間には、コイルスプリング18の初期長さL1分の広い間隔が確保されているので、易変形断熱材9を押し込みやくなっている。   Next, the heat insulation inner wall panel 3 is built. That is, as shown in FIG. 10, the heat insulating inner wall panel 3 is placed from the left and right sides of the inner wall panel fixing bracket 4 fixed to the shaft assembly 2, and the inner wall frame backing plate 15 is placed along the outdoor side surface of the vertical column 6, and The joints 23 having a predetermined width are provided between the adjacent heat insulating inner wall panels 3. Here, as described above, since the easily deformable heat insulating material 9 is fixed to the vertical column 6 by the stud 12, as shown in FIG. 10, by grasping a place where the stud 12 is not present and pulling it away from the vertical column 6, A slight gap 24 can be formed between the easily deformable heat insulating material 9 and the vertical column 6. By inserting one end of the inner wall frame backing plate 15 into the gap 24, the inner wall frame backing plate 15 can be placed along the outdoor side surface of the vertical column 6. At this time, as shown in FIG. 3, the easily deformable heat insulating material 9 is pushed into the inner wall panel fixing bracket 4 side. Since a wide space corresponding to the initial length L1 of the coil spring 18 is secured between the inner wall frame backing plate 15 and the substrate 13, the easily deformable heat insulating material 9 is easily pushed.

次に、断熱内壁パネル3を軸組2に固定する。すなわち、図11に示すように、固定ボルト19の軸部19bにおける根元部分に、内壁枠押さえ板20を、切欠き20dを軸部19bに嵌合させるようにして装着し、その押圧面20aを縦柱6の段落ち部6bに当接させる。そして、固定ボルト19の頭部19aの十字溝19cにプラスドライバPD等を差し込んで右回転させることにより、固定ボルト19を屋外側へねじ込む。これに伴い、固定ボルト19の締結力が内壁枠押さえ板20を介して断熱内壁パネル3へと伝達されて、断熱内壁パネル3は屋外側へ移動を開始し、図4及び図5に示すように、パイプ部材16の屋外側端部16aが基板13の表面に当接することにより、断熱内壁パネル3は移動を停止する。この状態において、断熱内壁パネル3は、固定ボルト19の締結力によって屋外側へ押圧される内壁枠押さえ板20と、コイルスプリング18の付勢力によって屋内側へ押圧される内壁枠裏当て板15との間に挟持され、その位置が固定されるものとなっている。一方、易変形断熱材9は、断熱内壁パネル3が屋外側へ移動するに従って、内壁パネル固定金具4及び軸組2の形状に沿って弾性変形し、断熱内壁パネル3の固定が完了した時には、図4及び図12に示すように、縦柱6と軸組2との間の空間11に隙間なく充填されるものとなっている。   Next, the heat insulating inner wall panel 3 is fixed to the shaft assembly 2. That is, as shown in FIG. 11, the inner wall frame pressing plate 20 is attached to the root portion of the shaft portion 19b of the fixing bolt 19 so that the notch 20d is fitted to the shaft portion 19b, and the pressing surface 20a is attached. The vertical column 6 is brought into contact with the stepped portion 6b. Then, by inserting a Phillips screwdriver PD or the like into the cross groove 19c of the head 19a of the fixing bolt 19 and rotating it to the right, the fixing bolt 19 is screwed to the outdoor side. Along with this, the fastening force of the fixing bolt 19 is transmitted to the heat insulating inner wall panel 3 through the inner wall frame pressing plate 20, and the heat insulating inner wall panel 3 starts to move to the outdoor side, as shown in FIGS. Furthermore, when the outdoor side end 16a of the pipe member 16 contacts the surface of the substrate 13, the heat insulating inner wall panel 3 stops moving. In this state, the heat insulating inner wall panel 3 includes an inner wall frame pressing plate 20 that is pressed to the outdoor side by the fastening force of the fixing bolt 19, and an inner wall frame backing plate 15 that is pressed to the indoor side by the biasing force of the coil spring 18. And the position is fixed. On the other hand, the easily deformable heat insulating material 9 is elastically deformed along the shapes of the inner wall panel fixing bracket 4 and the shaft assembly 2 as the heat insulating inner wall panel 3 moves to the outdoor side, and when the fixing of the heat insulating inner wall panel 3 is completed, As shown in FIGS. 4 and 12, the space 11 between the vertical column 6 and the shaft assembly 2 is filled without a gap.

次に、内壁部1の仕上がり状態を確認する。すなわち、図に詳細は示さないが、水糸またはクロスライン等を用いて断熱内壁パネル3の通りを測定し、ボード定規等を用いて断熱内壁パネル3の建ちを測定し、これらが予め定められた基準値内に入っているかどうかを確認する。   Next, the finished state of the inner wall 1 is confirmed. That is, although details are not shown in the figure, the streets of the heat-insulated inner wall panel 3 are measured using a water thread or a cross line, and the building of the heat-insulated inner wall panel 3 is measured using a board ruler or the like. Check whether it is within the standard value.

最後に、仕上がり状態に応じて断熱内壁パネル3の位置を微調整する。すなわち、断熱内壁パネル3の建ち・通りの測定結果が基準値内に入っていない場合、これを基準値内に入るよう修正する。この場合、図に詳細は示さないが、固定ボルト19の頭部19aの十字溝19cにプラスドライバPD等を差し込んで左回転させることにより屋内側へ若干戻す。これに伴い、断熱内壁パネル3も屋内側へ若干移動するので、その位置を屋内側へ微調整することができる。このように、断熱内壁パネル3を所望の距離だけ屋内側へ移動させた後、再びその建ち・通りを測定する。測定結果が基準値内に入っていなければ、断熱内壁パネル3の屋内側への移動と、建ち・通りの測定とを、測定結果が基準値内に入るまで繰り返す。   Finally, the position of the heat insulating inner wall panel 3 is finely adjusted according to the finished state. That is, when the measurement result of the building / street of the heat insulating inner wall panel 3 does not fall within the reference value, it is corrected to fall within the reference value. In this case, although details are not shown in the drawing, a plus driver PD or the like is inserted into the cross groove 19c of the head 19a of the fixing bolt 19 and rotated counterclockwise to slightly return to the indoor side. Along with this, the heat insulating inner wall panel 3 also moves slightly indoors, so that the position can be finely adjusted indoors. In this manner, after moving the heat insulating inner wall panel 3 to the indoor side by a desired distance, the building / street is measured again. If the measurement result does not fall within the reference value, the movement of the heat insulation inner wall panel 3 to the indoor side and the measurement on the building / street are repeated until the measurement result falls within the reference value.

以上述べたように、本発明に係る内壁パネル固定金具4によれば、断熱内壁パネル3を、内壁枠8と軸組2との間の空間11を広く確保した状態で建て込み、その後に屋外側へ移動させて所定位置で軸組2に固定することができる。従って、断熱内壁パネル3の建て込み時に、内壁枠8の屋外側面8aを覆って設けられた易変形断熱材9を、内壁枠8と軸組2との間の空間11に容易に押し込むことができ、且つ、固定ボルト19を屋外側へねじ込むだけの簡易な作業により、易変形断熱材9を前記空間11に隙間なく充填させることができる。これにより、内壁部1の高い断熱性能を容易且つ確実に達成することができる。また、断熱内壁パネル3を軸組2に固定した後に、その仕上がり状態に応じて、屋内側からの簡易な作業により断熱内壁パネル3の位置を屋内側に微調整することができる。これにより、内壁部1において高い精度の仕上がりを達成することができる。尚、内壁パネル固定金具4は、本実施例では、内壁部1において断熱内壁パネル3を軸組2に固定するものとして用いているが、基板13や係止部材14等の形状を適宜変更することにより、内壁部1以外の場所においても、パネル化された部材の固定金具として使用することが可能である。   As described above, according to the inner wall panel fixing bracket 4 according to the present invention, the heat insulating inner wall panel 3 is built in a state in which the space 11 between the inner wall frame 8 and the shaft assembly 2 is widely secured, and then the house It can be moved to the outside and fixed to the shaft set 2 at a predetermined position. Therefore, when the heat insulating inner wall panel 3 is built, the easily deformable heat insulating material 9 provided so as to cover the outdoor side surface 8a of the inner wall frame 8 can be easily pushed into the space 11 between the inner wall frame 8 and the shaft assembly 2. The easily deformable heat insulating material 9 can be filled in the space 11 without a gap by a simple operation of simply screwing the fixing bolt 19 to the outdoor side. Thereby, the high heat insulation performance of the inner wall part 1 can be achieved easily and reliably. Further, after fixing the heat insulating inner wall panel 3 to the shaft assembly 2, the position of the heat insulating inner wall panel 3 can be finely adjusted to the indoor side by a simple operation from the indoor side according to the finished state. Thereby, a highly accurate finish can be achieved in the inner wall portion 1. In the present embodiment, the inner wall panel fixing bracket 4 is used to fix the heat insulating inner wall panel 3 to the shaft assembly 2 in the inner wall portion 1, but the shape of the substrate 13, the locking member 14 and the like is appropriately changed. Thus, it can be used as a fixing member for a panelized member at a place other than the inner wall portion 1.
