【発明の属する技術分野】
本発明は、構造用パネルに関し、詳しくは、軽量であって取扱い性に優れ、木造建物の軸組材に対する組付け施工を一人作業で容易に且つ正確に行うことが出来、しかも、保管や運搬のスペースを低減することが出来る構造用パネルに関する。以下の説明において、「構造用パネル」は適宜「パネル」と略称する。
【０００２】
【従来の技術】
木造住宅の一般的な躯体構造である軸組構造においては、耐震強度などを向上させるため、筋交に替えて構造用面材や構造用パネルを組付ける試みがなされている。図６は従来例の板材のみから成る構造用面材（Ａ）の組付け状態を示す縦断面図、図７は構造用面材（Ａ）の組付け状態を示す横断面図、図８は従来例の耳付き状の構造用パネル（Ｂ）の組付け状態を示す縦断面図、図９は構造用パネル（Ｂ）の組付け状態を示す横断面図、図１０は従来例の耳無し状の構造用パネル（Ｃ）の組付け状態を示す縦断面図、図１１は構造用パネル（Ｃ）の組付け状態を示す横断面図である。
【０００３】
板材のみから成る構造用面材（Ａ）は、図６及び図７に示す様に、その周縁部が軸組材（Ｄ）の室外側の面に釘打ちされる。また、耳付き状の構造用パネル（Ｂ）は、図８及び図９に示す様に、方形に組まれた枠（Ｂ１）が軸組材（Ｄ）、（Ｄ）間に嵌込まれ、枠（Ｂ１）の片面に付設された構造用面材（Ｂ２）の周縁部が軸組材（Ｄ）、（Ｄ）の室外側の面に釘打ちされる。さらに、耳無し状の構造用パネル（Ｃ）は、図１０及び図１１に示す様に、方形に組まれた枠（Ｃ１）がその片面に付設された構造用面材（Ｃ２）と共に軸組材（Ｄ）、（Ｄ）間に嵌込まれ、かつ、枠（Ｃ１）がその内側から軸組材（Ｄ）、（Ｄ）に釘打ちされる。なお、釘打ちは、所定の基準に基づいて行われる。
【０００４】
【発明が解決しようとする課題】
ところで、図６、図７に示した構造用面材（Ａ）は、軸組材（Ｄ）に対する仮止め手段が全くないため、組付け施工にあたっては、軸組材（Ｄ）の室外側の面に押し付けて所定位置に位置決めし、その状態で周縁部を釘打ちしなければならない。このため、構造用面材（Ａ）は、軽量であるにも拘らず、これを一人作業によって位置ずれなく正確に組付け施工することは甚だ困難であり、二人作業を余儀なくされている。
【０００５】
一方、図８、図９に示した耳付き状の構造用パネル（Ｂ）及び図１０、図１１に示した耳無し状の構造用パネル（Ｃ）は、いずれも枠（Ｂ１）、（Ｃ１）が３ｃｍ×１０ｃｍ程度の断面形状であって、相当に重量が嵩むため、取扱い性が悪い。また、上記パネル（Ｂ）、（Ｃ）は、枠（Ｂ１）、（Ｃ１）により全体の厚みが１０ｃｍ以上となり、上下に積重ねた場合に嵩張るため、運搬や保管のスペースが増大するという問題がある。さらに、パネル（Ｂ）、（Ｃ）は、枠（Ｂ１）、（Ｃ１）が大き過ぎると軸組材（Ｄ）、（Ｄ）間に嵌込むことが出来ず、小さ過ぎると軸組材（Ｄ）との間に隙間が生じて枠（Ｂ１）、（Ｃ１）による強度付加が期待できないため、枠（Ｂ１）、（Ｃ１）を高精度に加工する必要があり、その加工コストが嵩むという問題もある。
【０００６】
本発明は、前記の実情に鑑みなされたものであり、その主たる目的は、軽量であって取扱い性に優れ、木造建物の軸組材に対する組付け施工を一人作業で容易に且つ精度よく行うことが出来、しかも、保管や運搬のスペースを低減することが出来る構造用パネルを提供することにある。
【０００７】
【課題を解決するための手段】
前記の目的を達成するため、本発明に係る構造用パネルは、木造建物の躯体を構成するパネルであって、周縁部が軸組材の室外側の面に接合される構造用面材と、当該構造用面材の室内側の面に付設され且つ下側の水平な軸組材の上面に当接可能な位置決め用の下部水平部材と、構造用面材の室内側の面の幅方向中央部に付設され且つ内装下地材の裏当て材として機能する中央垂直部材とを備えていることを特徴とする。
【０００８】
本発明の構造用パネルにおいて、軸組内の結露を防止し、躯体の防湿性能を向上させるため、構造用面材の室外側の面には、透湿防水シートが貼設され且つ通気層形成用の縦胴縁が付設されているのが好ましい。
【０００９】
【発明の実施の形態】
以下、図面を参照して本発明に係る構造用パネルを説明する。図１は構造用パネルの組付け状態を示す正面図、図２は構造用パネルの組付け状態を示す縦断面図、図３は構造用パネルの組付け状態を示す横断面図、図４は構造用パネルの積重ね状態を示す縦断面図は、図５は構造用パネルの積重ね状態を示す横断面図である。
【００１０】
本発明の構造用パネルは、図１〜図３に示す様に、木造建物の躯体を構成するパネル（１）であって、周縁部が軸組材の室外側の面に接合される構造用面材（２）と、構造用面材（２）の室内側の面に付設され且つ下側の水平な軸組材の上面に当接可能な位置決め用の下部水平部材（３）と、構造用面材（２）の室内側の面の幅方向中央部に付設され且つ内装下地材に当接可能な裏当て材として機能する中央垂直部材（４）とを備えている。
【００１１】
また、軸組内の結露を防止し、躯体の防湿性能を向上させるための好ましい態様として、構造用面材（２）の室外側の面には、透湿防水シート（５）が貼設され且つ通気層形成用の縦胴縁（６）が付設されている。さらに、構造用面材（２）の上部および下部には、軸組材の内側空間に連通可能な水蒸気拡散用の複数の小孔（７）が横方向に配列して形成されている。
【００１２】
軸組材は、垂直な軸組材としての柱（８Ａ）、（８Ａ）と、上側の水平な軸組材としての胴差（８Ｂ）と、下側の水平な軸組材としての土台（８Ｃ）とを含む。通常、柱（８Ａ）、（８Ａ）間の内法は約８００ｍｍ、胴差（８Ｂ）と土台（８Ｃ）との間の内法は約２６００ｍｍに設定される。そして、これらの柱（８Ａ）、（８Ａ）、胴差（８Ｂ）及び土台（８Ｃ）の室外側の面に対し、構造用面材（２）の周縁部が所定の基準に基づいて釘打ちされる。
【００１３】
構造用面材（２）としては、約７〜１２ｍｍ程度の厚さの構造用合板が一般的に使用されるが、例えば、建設省告示第１１００号に規定された構造用面材、または、これと同等以上の強度を有する限り、金属、樹脂、無機質などの各種の材料から成る単板、又はこれらの複合板を使用してもよい。構造用面材（２）の外形寸法は、施工部位の幅および高さに応じ、軸組材に対する周縁部の接合幅を５０ｍｍ程度確保できる様に、縦横それぞれ軸組材間の寸法より１００ｍｍ程度大きく設定される。例えば、胴差（８Ｂ）と土台（８Ｃ）との間の内法が約２６００ｍｍで柱（８Ａ）、（８Ａ）間の内法が約８００ｍｍの場合、構造用面材（２）は、縦が約２７００ｍｍ、横が約９００ｍｍに設定される。
【００１４】
下部水平部材（３）としては、構造用面材（２）と直交する方向の厚さが前記土台（８Ｃ）の奥行寸法より小さい３０〜６０ｍｍ、幅が約２０〜２５ｍｍの断面寸法を有し、長さが柱（８Ａ）、（８Ａ）間の内法より２ｍｍ程度短く設定された角材が一般に使用される。そして、この下部水平部材（３）は、構造用面材（２）の下縁部に沿って配置され、釘、ネジ、接着剤またはこれらの併用により構造用面材（２）の室内側の面に固定される。
【００１５】
中央垂直部材（４）としては、構造用面材（２）と直交する方向の厚さが前記軸組材の奥行寸法より小さい６０〜１０５ｍｍ、幅が約３０ｍｍの断面寸法を有し、長さが下部水平部材（３）と胴差（８Ｂ）間の内法より２ｍｍ程度短く設定された角材が一般に使用される。そして、この中央垂直部材（４）は、下部水平部材（３）と直交して構造用面材（２）の幅方向中央部に配置され、釘、ネジ、接着剤またはこれらの併用により構造用面材（２）の室内側の面に固定される。
【００１６】
透湿防水シート（５）は、微多孔性のプラスチックシートやフィルム、プラスチック細繊維の不織布などから成り、水蒸気を透過し、水を遮断する機能を有する。この透湿防水シート（５）の大きさは、隣接するパネル（１）の透湿防水シート（５）と相互に約１００ｍｍ程度オーバラップする様に、構造用面材（２）の周縁から張り出すことが好ましい。
【００１７】
縦胴縁（６）は、厚さが約２０ｍｍ、幅が約４０ｍｍの断面寸法を有し、長さが胴差（８Ｂ）と土台（８Ｃ）間の内法と略同程度に設定された木桟が一般に使用される。そして、この縦胴縁（６）は、中央垂直部材（４）に沿って配置され、釘、ネジ、接着剤またはこれらの併用により構造用面材（２）の室外側の面に固定される。
【００１８】
各小孔（７）は、胴差（８Ｂ）の下面および下部水平部材（３）の上面に沿って構造用面材（２）の上部および下部にそれぞれ横一列に配列されている。各小孔（７）の直径は、３〜３０ｍｍの範囲を目度とし、好ましくは、１０ｍｍ程度とされる。この場合、各小孔（７）は、その直径の３倍以上の距離を開けて配置するのが好ましい。また、各小孔（７）の総開口面積は、構造用面材（２）との面積比率で１〜１０％の範囲を目度とし、好ましくは、１〜５％程度とされる。
【００１９】
以上の様に構成された本発明のパネル（１）は、例えば、柱（８Ａ）、（８Ａ）、胴差（８Ｂ）及び土台（８Ｃ）の室外側の面に構造用面材（２）の周縁部が釘打ちされることにより、木造建物の躯体の一部を構成する。この組付け施工に際しては、先ず、軸組材の室外側から土台（８Ｃ）の上面に位置決め用の下部水平部材（３）を載せる。続いて、パネル（１）を略垂直に立て、構造用面材（２）を柱（８Ａ）、（８Ａ）に対して左右方向に位置決めする。そして、構造用面材（２）の周縁部を柱（８Ａ）、（８Ａ）、胴差（８Ｂ）及び土台（８Ｃ）の室外側の面に釘打ちする。
【００２０】
本発明のパネル（１）においては、縦胴縁（６）が構造用面材（２）の幅方向中央部に位置して上下に延びているため、縦胴縁（６）に外装材を固定して構造用面材（２）と外装材との間に通気層を形成することが出来る。この場合、透湿防水シート（５）により室内側への雨水の浸入が防止され、しかも、柱（８Ａ）、（８Ａ）と胴差（８Ｂ）と土台（８Ｃ）とで囲まれた軸組材の内側空間に滞留する水蒸気が各小孔（７）及び透湿防水シート（５）を介して通気層側へ排出されるため、軸組材の内側に結露の発生し難い防湿性能の高い躯体構造が得られる。
【００２１】
本発明のパネル（１）は、構造用面材（２）に位置決め用の下部水平部材（３）及び内装下地材の裏当て材として機能する中央垂直部材（４）が付設された簡単な構造であるため、図８及び図９に示した耳付き状の構造用パネル（Ｂ）や図１０及び図１１に示した耳無し状の構造用パネル（Ｃ）に比較して軽量であり、取扱い作業性に優れる。
【００２２】
また、本発明のパネル（１）は、前述の様に、木造建物の躯体の施工に際し、構造用面材（２）を左右方向に位置決めするだけで、軸組材に対して上下左右方向に正確に位置決めすることが出来る。従って、軸組材に対する組付け施工を一人作業で容易に且つ正確に行うことが出来る。
【００２３】
さらに、本発明のパネル（１）は、これを二枚重ねる場合、構造用面材（２）を外側にし、下部水平部材（３）同士が干渉しない様に天地を相互に逆向きにし、中央垂直部材（４）同士が干渉しない様に幅方向に相互に位置をずらすことにより、厚みを薄くして重ねることが出来る。従って、図４及び図５に示す様に、保管や運搬に際してコンパクトに積重ねることが出来、スペースを低減することが出来る。
【００２４】
【発明の効果】
以上説明した様に、本発明の構造用パネルは、構造用面材に位置決め用の下部水平部材および内装下地材の裏当て材として機能する中央垂直部材が付設された簡単な構造であるため、方形に組まれた枠の片面に構造用面材が貼着された従来の構造用パネルに比較して軽量であり、取扱い性に優れる。
【００２５】
また、本発明の構造用パネルは、木造建物の躯体の施工に際し、下側の水平な軸組材の上面に位置決め用の下部水平部材を載せ、構造用面材を左右方向に位置決めするだけで、軸組材に対して上下左右方向に正確に位置決めすることが出来る。従って、本発明の構造用パネルによれば、軸組材に対する組付け施工を一人作業で容易に且つ正確に行うことが出来る。
【００２６】
本発明の構造用パネルを二枚重ねる場合、構造用面材を外側にし、下部水平部材同士が干渉しない様に天地を相互に逆向きにし、中央垂直部材同士が干渉しない様に幅方向に相互に位置をずらすことにより、厚みを薄くして重ねることが出来る。従って、本発明の構造用パネルは、保管や運搬に際してコンパクトに積重ねることが出来、スペースを低減することが出来る。
【００２７】
本発明の構造用パネルにおいて、構造用面材の室外側の面に透湿防水シートが貼設され且つ通気層形成用の縦胴縁が付設されている場合、透湿防水シートにより室内側への雨水の浸入が防止され、かつ、通気層を介して水蒸気を外部に排出することが可能であるため、軸組材の内側の結露を防止でき、躯体の防湿性能を向上させることが出来る。

FIG. 6 is a longitudinal sectional view showing the assembled state of the structural face material (A) consisting only of the plate material of the conventional example, FIG. 7 is a transverse sectional view showing the assembled state of the structural face material (A), and FIG. FIG. 9 is a cross-sectional view showing the assembled state of the structural panel (B) of the conventional example, FIG. 9 is a transverse sectional view showing the assembled state of the structural panel (B), and FIG. FIG. 11 is a cross-sectional view showing the assembled state of the structural panel (C), and FIG. 11 is a transverse sectional view showing the assembled state of the structural panel (C).
[0003]
As shown in FIGS. 6 and 7, the peripheral surface of the structural surface material (A) made of only the plate material is nailed to the outdoor surface of the shaft assembly material (D). Moreover, as shown in FIG.8 and FIG.9, as for the structural panel (B) with an ear | edge, the frame (B1) assembled in the rectangle is inserted between shaft assembly materials (D) and (D), The peripheral edge portion of the structural face material (B2) provided on one side of the frame (B1) is nailed to the outer surface of the shaft assembly materials (D) and (D). Further, as shown in FIG. 10 and FIG. 11, the earless structural panel (C) is assembled with a structural frame material (C2) in which a rectangular frame (C1) is attached to one side. It is inserted between the materials (D) and (D), and the frame (C1) is nailed to the shaft assembly materials (D) and (D) from the inside. Note that nailing is performed based on a predetermined standard.
[0004]
[Problems to be solved by the invention]
By the way, the structural face material (A) shown in FIGS. 6 and 7 has no temporary fixing means for the shaft assembly material (D). It must be pressed against the surface and positioned at a predetermined position, and the peripheral edge must be nailed in that state. For this reason, although the structural face material (A) is light, it is extremely difficult to assemble and install it without any positional shift by one person's work, and two persons are forced to work.
[0005]
On the other hand, the structural panel (B) with ears shown in FIGS. 8 and 9 and the structural panel (C) without ears shown in FIGS. 10 and 11 are both frame (B1), (C1 ) Is a cross-sectional shape of about 3 cm × 10 cm, and the weight is considerably increased, so that the handleability is poor. Further, the panels (B) and (C) have a total thickness of 10 cm or more due to the frames (B1) and (C1), and are bulky when stacked up and down, which increases the space for transportation and storage. is there. Furthermore, if the frames (B1) and (C1) are too large, the panels (B) and (C) cannot be fitted between the shaft assemblies (D) and (D). D) and a gap is created between the frames (B1) and (C1), and it is not expected to add strength. Therefore, it is necessary to process the frames (B1) and (C1) with high accuracy, which increases the processing cost. There is also a problem.
[0006]
The present invention has been made in view of the above circumstances, and its main purpose is to be lightweight and excellent in handleability, and to easily and accurately perform assembly work on a shaft assembly of a wooden building by one person. It is another object of the present invention to provide a structural panel that can reduce the storage and transportation space.
[0007]

[0008]
In the structural panel of the present invention, in order to prevent dew condensation in the frame and to improve the moisture-proof performance of the housing, a moisture-permeable waterproof sheet is affixed to the outer surface of the structural face material and a ventilation layer is formed. It is preferable that a vertical trunk edge is attached.
[0009]

FIG. 5 is a cross-sectional view showing the stacked state of the structural panels, and FIG. 5 is a cross-sectional view showing the stacked state of the structural panels.
[0010]
As shown in FIGS. 1 to 3, the structural panel of the present invention is a panel (1) that constitutes a frame of a wooden building, and its peripheral portion is joined to the outdoor surface of the frame assembly. A face member (2), a lower horizontal member (3) for positioning, which is attached to the indoor surface of the structural face member (2) and can be brought into contact with the upper surface of the lower horizontal shaft assembly; A central vertical member (4) functioning as a backing material attached to the center in the width direction of the indoor side surface of the face material (2) and capable of contacting the interior base material.
[0011]
In addition, as a preferable mode for preventing condensation in the shaft assembly and improving the moisture-proof performance of the housing, a moisture-permeable waterproof sheet (5) is attached to the outdoor surface of the structural face material (2). In addition, a vertical trunk edge (6) for forming a ventilation layer is attached. Further, a plurality of small holes (7) for diffusing water vapor that can communicate with the inner space of the shaft assembly are formed in the upper and lower portions of the structural face material (2).
[0012]
The shaft assembly is composed of columns (8A) and (8A) as vertical shaft assemblies, a trunk difference (8B) as an upper horizontal shaft assembly, and a foundation (8B) as a lower horizontal shaft assembly. 8C). Usually, the inner method between the columns (8A) and (8A) is set to about 800 mm, and the inner method between the trunk difference (8B) and the base (8C) is set to about 2600 mm. Then, the peripheral edge of the structural face material (2) is nailed based on a predetermined standard with respect to the outdoor side surfaces of the pillars (8A), (8A), the trunk difference (8B), and the base (8C). Is done.
[0013]
As the structural face material (2), a structural plywood having a thickness of about 7 to 12 mm is generally used. For example, the structural face material specified in Ministry of Construction Notification No. 1100, or A single plate made of various materials such as metals, resins, and inorganic materials, or a composite plate thereof may be used as long as it has a strength equal to or higher than this. The external dimension of the structural face material (2) is about 100 mm longer than the dimension between the shaft assemblies in the vertical and horizontal directions so that the joint width of the peripheral edge to the shaft assembly can be secured about 50 mm according to the width and height of the construction site. It is set large. For example, when the inner method between the trunk difference (8B) and the base (8C) is about 2600 mm and the inner method between the columns (8A) and (8A) is about 800 mm, the structural face material (2) Is set to about 2700 mm, and the width is set to about 900 mm.
[0014]
The lower horizontal member (3) has a cross-sectional dimension in which the thickness in the direction orthogonal to the structural face material (2) is 30 to 60 mm smaller than the depth dimension of the base (8C) and the width is about 20 to 25 mm. In general, a square member whose length is set to be about 2 mm shorter than the inner method between the columns (8A) and (8A) is generally used. And this lower horizontal member (3) is arrange | positioned along the lower edge part of structural surface material (2), and the indoor side of structural surface material (2) is carried out by a nail, a screw, adhesives, or these combination. Fixed to the surface.
[0015]
The central vertical member (4) has a cross-sectional dimension in which the thickness in the direction orthogonal to the structural face material (2) is 60 to 105 mm smaller than the depth dimension of the shaft assembly, and the width is about 30 mm. However, a square member is generally used which is set to be shorter by about 2 mm than the inner method between the lower horizontal member (3) and the trunk difference (8B). The central vertical member (4) is arranged at the center in the width direction of the structural face material (2) perpendicular to the lower horizontal member (3), and is structured by nails, screws, adhesives or a combination thereof. The face material (2) is fixed to the indoor surface.
[0016]
The moisture permeable waterproof sheet (5) is made of a microporous plastic sheet or film, a plastic fine fiber nonwoven fabric, or the like, and has a function of transmitting water vapor and blocking water. The moisture-permeable waterproof sheet (5) is stretched from the periphery of the structural face material (2) so as to overlap the moisture-permeable waterproof sheet (5) of the adjacent panel (1) by about 100 mm. It is preferable to put out.
[0017]
The longitudinal trunk edge (6) has a cross-sectional dimension of about 20 mm in thickness and about 40 mm in width, and the length is set to be approximately the same as the inner method between the trunk difference (8B) and the base (8C). Wooden crossing is generally used. And this vertical trunk edge (6) is arrange | positioned along a center perpendicular | vertical member (4), and is fixed to the outdoor side surface of a structural face material (2) by a nail, a screw, adhesives, or these combination. .
[0018]
The small holes (7) are arranged in a horizontal row on the upper and lower portions of the structural face material (2) along the lower surface of the trunk difference (8B) and the upper surface of the lower horizontal member (3). The diameter of each small hole (7) is in a range of 3 to 30 mm, and preferably about 10 mm. In this case, each small hole (7) is preferably arranged with a distance of three times or more of its diameter. Further, the total opening area of each small hole (7) is set to a range of 1 to 10% as an area ratio with the structural face material (2), and preferably about 1 to 5%.
[0019]
The panel (1) of the present invention configured as described above has, for example, a structural face material (2) on the outdoor side surface of the columns (8A), (8A), the trunk difference (8B), and the base (8C). A part of the frame of the wooden building is formed by nailing the peripheral edge of the frame. In this assembly work, first, the lower horizontal member (3) for positioning is placed on the upper surface of the base (8C) from the outdoor side of the shaft assembly. Subsequently, the panel (1) is erected substantially vertically, and the structural face material (2) is positioned in the left-right direction with respect to the columns (8A) and (8A). Then, the peripheral edge of the structural face material (2) is nailed to the outer surfaces of the columns (8A), (8A), the trunk difference (8B), and the base (8C).
[0020]
In the panel (1) of the present invention, since the vertical trunk edge (6) is located at the center in the width direction of the structural face material (2) and extends vertically, an exterior material is provided on the vertical trunk edge (6). By fixing, a ventilation layer can be formed between the structural face material (2) and the exterior material. In this case, the moisture-permeable waterproof sheet (5) prevents rainwater from entering the room, and the shaft assembly is surrounded by the pillars (8A) and (8A), the trunk difference (8B), and the base (8C). Since water vapor staying in the inner space of the material is discharged to the ventilation layer side through each small hole (7) and the moisture permeable waterproof sheet (5), it has high moisture proof performance that hardly causes condensation on the inside of the shaft assembly. A frame structure is obtained.
[0021]
The panel (1) of the present invention has a simple structure in which a structural lowering member (2) is attached with a lower horizontal member (3) for positioning and a central vertical member (4) functioning as a backing material for interior base materials. Therefore, it is lighter than the structural panel (B) with ears shown in FIG. 8 and FIG. 9 and the structural panel (C) without ears shown in FIG. 10 and FIG. Excellent workability.
[0022]
Further, as described above, the panel (1) of the present invention can be moved vertically and horizontally with respect to the shaft assembly by simply positioning the structural face material (2) in the left-right direction when constructing the frame of the wooden building. Accurate positioning is possible. Therefore, the assembly work for the shaft assembly can be easily and accurately performed by one person.

【The invention's effect】
As described above, the structural panel according to the present invention has a simple structure in which a structural vertical member is provided with a lower vertical member for positioning and a central vertical member that functions as a backing material for interior base materials. Compared to a conventional structural panel in which a structural face material is bonded to one side of a rectangular frame, the frame is lighter and easier to handle.
[0025]
In addition, the structural panel of the present invention can be obtained by placing a lower horizontal member for positioning on the upper surface of the lower horizontal shaft assembly and positioning the structural surface material in the left-right direction when constructing the frame of the wooden building. It is possible to accurately position the shaft assembly in the vertical and horizontal directions. Therefore, according to the structural panel of the present invention, the assembly work for the shaft assembly can be easily and accurately performed by one person.
