Description

本願発明は、木造軸組工法に用いる耐力面材と耐力面構造に関し、特に、構造用軸組材である木軸（柱又は間柱）と同様の木軸材を用いて形成した耐力面材と、これを用いた耐力面構造に関する。 The present invention relates to a load bearing surface material and a load bearing surface structure used in a wooden shaft assembly method, and in particular, a load bearing surface material formed using a tree shaft material similar to a wooden shaft (column or intercolumn) which is a structural shaft assembly material, and The present invention relates to a load bearing surface structure using the same.

木造軸組工法の耐力面の構築において、特に、耐力壁面の構築の場合、土台に所定間隔で柱を立設固定し、この柱間に筋交いを取り付けて壁の耐力を確保している。そして、この柱間に断熱材や防音材を充填させて後、合板やサイディングなどの面材を取り付ける工法を採っているのが一般的である。 In the construction of the load bearing surface of the wooden frame construction method, particularly in the case of building a load bearing wall, pillars are erected and fixed at predetermined intervals on the base, and bracing is attached between the pillars to ensure the wall bearing strength. In general, a method of attaching a face material such as plywood or siding after filling the pillars with a heat insulating material or a soundproofing material is employed.

近年、これに変わるものとして、柱間に構造用面材を取り付け、筋交いと断熱材充填を省略して工法の簡易化と工期の短縮化を図った種々構成のものが開示されている。 In recent years, various constructions have been disclosed in which structural face materials are attached between pillars, bracing and insulation filling are omitted, and the construction method is simplified and the construction period is shortened.

その一例となる特許文献１（発明の名称「木造建築」）には、柱材と同じ角寸法の角材の複数本を側面に形成した溝条と突条で嵌合させると共に、これらの角材を横方向に貫通させた金属線材（ボルト）を金属ナットで緊締してパネルを形成し、このパネルを構成する角材を立てた状態（垂直方向）にして柱間に取り付ける木造建築の耐力面構造が開示されていた。 In Patent Document 1 (name of the invention “wooden building”) as an example thereof, a plurality of square members having the same angular dimensions as the pillar members are fitted with grooves and protrusions formed on the side surfaces, and these square members are used. The metal wire rod (bolt) penetrated in the horizontal direction is tightened with a metal nut to form a panel, and the wooden building bearing surface structure attached between the pillars with the square members constituting this panel standing upright (vertical direction) It was disclosed.

その他、耐力面構造又は耐力壁として機能する耐力面材に関する従来技術としては、特許文献２（発明の名称「木造軸組工法における面材耐力壁パネル」）、及び特許文献３（発明の名称「建築用パネルとそれを使用した建築構造」）が開示されている。 In addition, as a prior art regarding a load bearing surface material that functions as a load bearing surface structure or a load bearing wall, Patent Document 2 (invention name “face material bearing wall panel in a wooden shaft construction method”) and Patent Document 3 (invention name “ Architectural panels and building structures using them ”) are disclosed.

特許文献２の開示発明は、含水率１５％以下まで機械乾燥させた８０ｍｍ以上２００ｍｍ以下の小角材の木口を接着接合し、長さ１０００ｍｍ以上１２００ｍｍ以下の長尺角材を形成し、さらにこの長尺小角材の側面を相互に接着剤にて接着して、幅を９００ｍｍ以上１２００ｍｍ以下の面材耐力壁パネルとするものである。 The disclosed invention of Patent Document 2 is formed by bonding and joining the ends of a small-corner material of 80 mm or more and 200 mm or less mechanically dried to a moisture content of 15% or less to form a long square material having a length of 1000 mm or more and 1200 mm or less. The side surfaces of the small square members are bonded to each other with an adhesive to form a face material bearing wall panel having a width of 900 mm or more and 1200 mm or less.

また特許文献３の開示発明は、建築用パネルにおいて、２本並べた芯持ちの棒材の溝に変形防止材を跨がせて配置し、この配置の繰り返しにより数本の棒材を並べ、並べた棒材を棒材連結具で貫通してパネル状に連結して形成しているものである。２本の棒材の溝には隙間防止材をも跨がせて配置している。 Moreover, the disclosure invention of patent document 3 arrange | positions a deformation | transformation prevention material over the groove | channel of the core-supported bar material which arranged two in the building panel, and arranges several bar materials by the repetition of this arrangement, It is formed by penetrating the arranged bars through a bar connector and connecting them in a panel shape. A gap prevention material is also straddled in the groove of the two bars.

しかしながら、特許文献１で開示された発明のパネルは、耐力面材（又は耐力壁）としては建築基準にあった壁耐力を十分に満たすものではなかった。すなわち、ボルト通し孔方向（ボルト軸方向）に繰り返し力が加わった場合（例えば、耐力壁の評価試験のような上部横方向の力が加わる場合）、ボルトやナットは金属であるためにパネル側の木製角材とは強度差があるため、角材側の座面にへこみが生じることとなり、ボルトとナットの締結状態が緩むことがあったからである。この緩みは適宜に増し締めしなければ拡大することになり、ひいては耐力面材としての強さの維持が困難になっていた。加えて、ボルトとナットによる締結は、長期経年による応力緩和やクリープが発生して締結力の低下が問題となっていた。 However, the panel of the invention disclosed in Patent Document 1 does not sufficiently satisfy the wall strength that meets the building standards as a load bearing surface (or bearing wall). In other words, when repeated force is applied in the bolt hole direction (bolt axis direction) (for example, when a force in the upper lateral direction is applied as in the evaluation test of the load bearing wall), the bolts and nuts are metal, so the panel side This is because there is a difference in strength from that of the wooden timber, so that a dent is generated on the bearing surface on the square timber side, and the fastening state of the bolt and nut may be loosened. This loosening will be enlarged if it is not properly tightened, and as a result, it has become difficult to maintain the strength as a load bearing face. In addition, when fastening with bolts and nuts, stress relaxation and creep occur over a long period of time, resulting in a problem of reduced fastening force.

また、引用文献２の面材耐力壁パネルは、複数種類の小角材を接着剤で所定長さに接合して長尺小角材を形成し、この長尺材の側面側どうしを複数接合して成るものである。このため、小角材から長尺小角材、長尺小角材から面材耐力壁パネルの形成時に大量の接着剤と接着工程が必要となり、量産効率が極めて悪いものであった。また、大量の接着材を使う環境は、環境保全の観点から高コストになるばかりでなく、ハウスシック症候群等の健康被害の発生が否定できないものであった。 Moreover, the face material bearing wall panel of the cited document 2 is formed by joining a plurality of types of small square materials to a predetermined length with an adhesive to form a long small square material, and joining a plurality of side surfaces of the long materials. It consists of. For this reason, a large amount of an adhesive and a bonding process are required when forming a small-sized square-shaped member to a long-sized small-sized member and a long-sized small-sized member to a face material bearing wall panel, and the mass production efficiency is extremely poor. In addition, the environment where a large amount of adhesive is used is not only costly from the viewpoint of environmental protection, but also health damage such as house sick syndrome cannot be denied.

引用文献３の建築用パネルにおいても、ボルトとナットの締結構造である点で引用文献１のパネルと変わりなく、木材側の座面にへこみが生じることにより、締結状態が緩むことが想定されるものであった。同様に、長期経年による締結力の低下も問題であった。 Also in the building panel of the cited document 3, it is assumed that the fastening state is loosened due to a dent in the seat surface on the wood side, which is the same as the panel of the cited document 1 in that it is a bolt and nut fastening structure. It was a thing. Similarly, a decrease in fastening force due to long-term aging has been a problem.

そこで、本願発明は、上記実情に鑑み発明されたものであり、簡易な構造でありながら強度が向上するだけでなく、長期経年による耐力低下を回避すると共に、複数の面材幅に迅速に対応できる耐力面材を提供するものである。さらに、これを用いて構築する木造軸組工法の耐力面構造を提供するものである。 Accordingly, the present invention has been invented in view of the above circumstances, and not only improves the strength while being a simple structure, but also avoids a decrease in yield strength due to long-term aging, and quickly responds to a plurality of face material widths. It provides a load-bearing face material that can be used. Furthermore, the load bearing surface structure of the wooden frame construction method constructed | assembled using this is provided.

本願発明にかかる木軸材構成の耐力面材（以下、「本面材」と称する。）は、以下の構成を特徴としている。 The load bearing face material (hereinafter referred to as “main face material”) having a wood shaft material structure according to the present invention is characterized by the following structure.

すなわち、角柱状の木軸材の複数本を側面当接させて面状に並設すると共に、隣接する木軸材どうしを直棒状の締結線材の複数箇所への貫入によって結着させたことを特徴としている。 That is, a plurality of prismatic wood shafts are side-by-side contacted and arranged side by side, and adjacent wood shaft materials are bonded by penetration of a plurality of straight rod-like fastening wires. It is a feature.

ここで、各木軸材は同一断面形とすると共に、締結線材は長尺状の木材用ビス又は木材用雄ネジであることを特徴としている。また、締結線材の貫入は、隣接する２本又は３本の木軸材への貫入であり、貫入方向についても木軸材の長さ方向に対して直角方向及び斜め方向のいずれか一方、又はこれらの組合せを採用したことを特徴としている。 Here, the wood shaft members have the same cross-sectional shape, and the fastening wire is a long wood screw or a wood external screw. Further, the penetration of the fastening wire is penetration into two or three adjacent wood shaft members, and the penetration direction is either one of a perpendicular direction and an oblique direction with respect to the length direction of the wood shaft material, or It is characterized by adopting these combinations.

上記木軸材の側面当接においては、側面に形成した凹条又は凸条の適合によるものであることを特徴としている。凹条及び凸条は、側面の一部又は全面に渡って形成しても良い。 The side contact of the wood shaft material is characterized by conforming a concave line or a convex line formed on the side surface. The concave stripe and the convex stripe may be formed over a part of the side surface or the entire surface.

また、前記凹凸条の当接適合が、木軸材の面取り成形に適合する凹条成形によるものであること特徴としている。より具体的には、一方の木軸材を面取り成形して側面全体を凸条形とし、他方の適合側は上記面取り部に適合する凹条を側面全体に成形している。 In addition, the conformity of the contact between the concave and convex strips is due to the concave strip forming adapted to the chamfering of the wood shaft material. More specifically, one wooden shaft material is chamfered to form a convex shape on the entire side surface, and the other conforming side is formed with a concave line that fits the chamfered portion on the entire side surface.

次に、本面材を用いた木造軸組工法の耐力面構造（以下、「本構造」と称する。）は、上記構成の耐力面材を、木造軸組工法の軸組材の間に取り付けたことを特徴としている。ここで、木造軸組工法の軸組材としては、例えば、通し柱や間柱、土台、及び桁や胴差し等を示し、これらから成る軸組材に取り付ける場合、壁面を構成する耐力面構造となる。他にも、土台、大引きで成る軸組材に配置すれば床面を構成する耐力面構造となり、桁、梁で成る軸組材に配置すれば天井面を構成する耐力面構造となる。 Next, the load-bearing surface structure of the wooden shaft construction method using the main face material (hereinafter referred to as “main structure”) is constructed by attaching the load bearing face material having the above structure between the shaft structure materials of the wooden shaft construction method. It is characterized by that. Here, as the shaft frame material of the wooden frame construction method, for example, through pillars, studs, foundations, girders, torches, etc. are shown. . In addition, if it is arranged on a shaft assembly made of a base and a large pull, it becomes a load bearing surface structure that constitutes a floor surface, and if it is arranged on a shaft assembly made of a girder and a beam, it becomes a load bearing surface structure that constitutes a ceiling surface.

また、本面材を構成する木軸材の断面形を、取付け対象である部位の軸組材の木軸と同一形としても良い。この場合、本面材と軸組材間には凹凸面が生じず、美観を確保できると共に余計な引っ掛かりもないため安全面も向上する。 Moreover, it is good also considering the cross-sectional shape of the wooden shaft material which comprises this face material as the same shape as the wooden shaft of the shaft assembly material of the site | part which is an attachment object. In this case, an uneven surface is not formed between the main face material and the shaft assembly material, and an aesthetic appearance can be ensured, and safety is improved because there is no extra catch.

本面材は上記構成を採用することにより、複数の木軸材間に跨るように貫入させた複数の締結線材によって木軸材の連結状態を高めることができる。本面材は、所定の外力が繰り返し作用しても複数箇所に配設した各締結線材が、隣接する木軸材どうしと個別的に結着しているため、面材の耐力低下を招くことはない。また、長期経年の作用によって生じる応力緩和やクリープは、各締結線材限りのものであって、かつその方向性が区々であるため、面材としての耐力を安定的に維持することができる。 By adopting the above-described configuration, the present face material can enhance the connection state of the wood shaft material by a plurality of fastening wire materials that penetrate between the plurality of wood shaft materials. Even if a predetermined external force is applied repeatedly, the fastening material is connected to the adjacent wooden shafts individually, resulting in a decrease in the proof stress of the facing material. There is no. Further, stress relaxation and creep caused by long-term aging are limited to each fastening wire, and the directionality thereof varies, so that the proof stress as a face material can be stably maintained.

また、締結線材の貫入方向を直角方向だけでなく斜め方向にして組み合わせた場合は、面材へ作用する外力を締結線材の貫入方向に適宜に分散することができるため、耐力面材をより強固に構築することかできる。 In addition, when the penetration direction of the fastening wire is combined not only in the perpendicular direction but also in the oblique direction, the external force acting on the face material can be appropriately dispersed in the penetration direction of the fastening wire, so that the load bearing face material is stronger. Can be built.

さらに、木軸材の側面当接を、凹条又は凸条の適合としているため、木軸材どうしの当接時や締結線材の貫入による位置ズレが抑制され、面材の面を一にした安定品質の耐力面材を形成することができる。 Furthermore, because the side contact of the wood shaft material is adapted to a concave or convex line, the displacement of the wood shaft material due to the contact between the wood shaft materials and the penetration of the fastening wire is suppressed, and the surface of the surface material is made uniform. Stable quality bearing materials can be formed.

次に、本面材を用いた本構造は、木造軸組工法の軸組材を構成する木軸と同様の木軸材を用いて構成しているため、筋交いや断熱材や防音材や保温材等を省略することができ、充填作業等の別作業をすることなく大工作業のみで構築できるため、作業効率と工期の短縮を図ることできる。特に、内装施工に関しては、木材の肌が表面に表れるので、これをそのまま内装仕上げとすることができ、材料削減や工期短縮、引いてはコスト削減にも資する。 Next, this structure using the main face material is composed of the same wooden shaft material as that of the wooden shaft material of the wooden shaft construction method, so bracing, heat insulation, soundproofing material and heat insulation Since materials and the like can be omitted, and construction can be performed only by carpenter work without performing separate work such as filling work, work efficiency and work period can be shortened. In particular, for interior construction, the skin of wood appears on the surface, so that it can be used as it is for interior finishing, which contributes to material reduction, shortening the construction period, and cost reduction.

また、軸組材を構成する木軸と同一形（同一寸法角）の木軸材を用いて耐力面材を形成した場合は、壁面や床面や天井面の内装面の工事を省略することができる。これにより、当該工事費の削減が図れるだけでなく、内装及び外装の美観向上にも寄与する。 In addition, when a load bearing surface material is formed using a wood shaft material that has the same shape (same size angle) as the wood shaft constituting the shaft assembly material, the construction of the interior surface of the wall surface, floor surface, or ceiling surface should be omitted. Can do. This not only reduces the construction cost, but also contributes to improving the aesthetics of the interior and exterior.

さらに、本願発明は、壁面構築においては本面材を構成する木軸材を縦方向にして立設させているため、地震による影響が大きい横揺れへの抵抗力をより高めることでき、木造軸組工法としては強度がより向上した耐力壁を構築することができる。この耐力壁の強度向上によって耐力壁数を減少できるために設計自由度が増すことになり、例えば、住宅に大きな開口部を設けることが可能となる。加えて、接着剤を使用しないため、ハウスシック症候群のおそれもなく、住環境にやさしいものである。 Furthermore, in the present invention, since the wooden shaft material constituting the main surface material is set up in the vertical direction in the wall surface construction, it is possible to further increase the resistance to rolling, which is greatly affected by the earthquake, As an assembling method, it is possible to construct a bearing wall with improved strength. Since the number of bearing walls can be reduced by improving the strength of the bearing walls, the degree of freedom in design increases. For example, a large opening can be provided in a house. In addition, since no adhesive is used, there is no risk of house sick syndrome and it is friendly to the living environment.

図１の図符号１は、本面材２を壁面として用いた本構造である。本構造１は、基礎９１の上面に載置した土台９２に所定の離隔距離で２本の柱９３を立設し、柱間の上部には桁９４を跨ぐように配設して木造軸組工法の軸組材９を成し、この軸組材内に本面材２を固定して構成している。 Reference numeral 1 in FIG. 1 is a main structure using the main face material 2 as a wall surface. In this structure 1, two pillars 93 are erected at a predetermined separation distance on a base 92 placed on the upper surface of a foundation 91, and arranged between the pillars so as to straddle the girders 94. A shaft assembly 9 of the construction method is formed, and the main surface material 2 is fixed in the shaft assembly.

なお、本面材２は、実施例のように壁面に限定するものでなく、取り付ける木造軸組工法の軸組材９によっては、壁面の他、床面や天井面として構成するようにしても良い。 In addition, this face material 2 is not limited to a wall surface like an Example, It may be made to comprise as a floor surface or a ceiling surface other than a wall surface depending on the frame material 9 of the wooden frame construction method to attach. good.

ここで、本面材２は、上述のように軸組材間に取り付けるものであり、土台９２、桁９４、柱９３に複数の専用の２種類の固定ビス６ａ、６ｂを用いて固定している。柱用に長めの固定ビス６ｂを用い、これを水平横方向から柱９３を突き通して本面材２の木場面に貫入させている。土台用には短めの固定ビス６ａを用い、本面材２から斜めに突き通し先端の一部を土台９２に貫入させている。桁用にも短めの固定ビス６ａを用い、これを桁９４から斜めに突き通し先端の一部を本面材２に貫入させるようにしている。なお、上記固定ビス６ａ、６ｂは、後述する締結線材５ａと同じ長尺状の木材用ビス又は木材用雄ネジである。また、本面材２と土台９２と接合部分は、ホゾとホゾ穴の係合としても良い（図示省略）。 Here, the main face material 2 is attached between the shaft assembly members as described above, and is fixed to the base 92, the girders 94, and the pillars 93 using a plurality of dedicated fixing screws 6a and 6b. Yes. A long fixed screw 6b is used for the pillar, and this is penetrated through the pillar 93 from the horizontal direction and penetrates into the wood scene of the main face material 2. A short fixed screw 6 a is used for the base, and a part of the tip is penetrated into the base 92 through the main face material 2 obliquely. A shorter fixed screw 6a is also used for the girder, which is obliquely penetrated from the girder 94 so that a part of the front end is penetrated into the main face material 2. The fixing screws 6a and 6b are the same long wood screws or male wood screws as a fastening wire 5a described later. Further, the main face material 2, the base 92, and the joining portion may be engaged with a tenon and a tenon hole (not shown).

次に、本面材２の詳細について説明する。本面材２は、同一断面及び同一長さの複数の角柱状の木軸材３、３、３、・・・から構成している。 Next, the details of the main face material 2 will be described. The face material 2 is composed of a plurality of prismatic wooden shaft members 3, 3, 3,... Having the same cross section and the same length.

この木軸材３は、対向側面の一方側の全長に渡って凸条３１を形成すると共に、他方側の対向面側には凹条３２を形成している。凸条３１は、長手側の両方の稜線部を面取り成形して全体で凸条３１を成し、凹条３２はこの凸条３１に適合するように稜線部の両端を残して全体を削った形状にしている。 This wood shaft material 3 forms a ridge 31 over the entire length of one side of the opposite side surface, and a recess 32 on the opposite side of the other side. The ridges 31 are formed by chamfering both ridge lines on the long side to form the ridges 31 as a whole, and the ridges 32 are shaved to leave the ends of the ridge lines so as to fit the ridges 31. It is in shape.

本面材２は、上記構成の複数の木軸材３の側面を接合させ、面状を成すように並設して構成している。この側面当接時には、側面の形成した上記凹条３２と凸条３１とを適合させている。そして、この並設状態の木軸材３に対し、少なくとも２本の木軸材３に跨る長さの直棒状の締結線材５ａを複数箇所へ貫入し、この締結線材５ａと各木軸材３とを結着させて一体化している。 The main face material 2 is formed by joining the side surfaces of a plurality of wood shaft members 3 having the above-described configuration so as to form a planar shape. At the time of the side surface contact, the concave line 32 and the convex line 31 formed on the side surface are adapted. And with respect to the tree shaft material 3 of this juxtaposed state, at least two straight rod-shaped fastening wires 5a straddling the tree shaft materials 3 are penetrated into a plurality of locations, and this fastening wire material 5a and each tree shaft material 3 are inserted. And united together.

ここで、本実施例の締結線材５ａは、長尺状の木材用ビス又は木材用雄ネジである。したがって、締結線材５ａのネジ部５１がその全長に渡って複数の木軸材３と深く結着していることとなる。 Here, the fastening wire 5a of the present embodiment is a long wood screw or a wood male screw. Therefore, the screw portion 51 of the fastening wire 5a is deeply connected to the plurality of wood shaft members 3 over the entire length thereof.

この締結線材５ａを貫入する木軸材３の高さ位置は、その側面の高さ寸法のほぼ中央とする一方、貫入方向は木軸材３の長さ方向に対して直角方向と斜め方向を組み合わせている。また、締結線材５ａの長さは、上述のように２本の木軸材３に跨る長さの他、３本の木軸材３に跨る合計２種類の寸法を設定している。ここで、２本の木軸材３に跨る長さの締結線材は短めの締結線材５ａと、３本の木軸材３に跨る長さの締結線材は長めの締結線材５ｂと、称して用いる。 The height position of the wood shaft material 3 penetrating the fastening wire 5a is set at the substantially center of the height dimension of the side surface, while the penetration direction is perpendicular to the length direction of the wood shaft material 3 and an oblique direction. Combined. Moreover, the length of the fastening wire 5a sets the dimension of two types in total straddling the three wood shaft materials 3 other than the length over the two wood shaft materials 3 as mentioned above. Here, the fastening wire having a length straddling the two wooden shaft members 3 is referred to as a short fastening wire 5a, and the fastening wire having a length straddling the three wooden shaft members 3 is referred to as a long fastening wire 5b. .

本面材２における複数の締結線材５ａ、５ｂの貫入態様は、中央に直角方向の貫入方向のグループ、その両側に中央に向かう斜め方向の貫入方向のグループ、その外側に直角方向の貫入方向のグループ、となるようにしている。 The plurality of fastening wires 5a and 5b in the main face member 2 are penetrated in a group in a perpendicular penetration direction at the center, a group in an oblique penetration direction toward the center on both sides, and a perpendicular penetration direction on the outer side. I try to be a group.

そして、上記構成の本面材２を、木軸材３が縦方向となるように土台９２に立設させた状態で柱９３の間に取付けて本構造１を構築している。この軸組材９への取付けにおいては、上述のように、横側は柱９３の外側から本面材２に向かって直角方向に複数の固定ビス６ｂを貫入し、下側は本面材２から土台９２に向かって斜め方向に複数の固定ビス６ａを貫入し、上側は桁９４から本面材２に向かって斜め方向に複数の固定ビス６ａを貫入して行っている。 Then, the main structure 2 is constructed by attaching the main surface material 2 having the above-described structure between the pillars 93 in a state where the main shaft material 3 is erected on the base 92 so that the wood shaft material 3 is in the vertical direction. In the attachment to the shaft assembly 9, as described above, the lateral side penetrates the plurality of fixing screws 6 b perpendicularly from the outside of the pillar 93 toward the main surface material 2, and the lower side is the main surface material 2. A plurality of fixing screws 6 a are inserted obliquely from the base 92 toward the base 92, and a plurality of fixing screws 6 a are inserted obliquely from the girder 94 toward the main surface material 2 on the upper side.

また、本面材２の左右に位置する柱９３については、木軸材３と当接状態を強固にすると共に隙間を生じさせないために、長さ方向に隣接する木軸材３と適合する凹条又は凸条を片側の側面にのみ形成している。 In addition, the pillars 93 located on the left and right sides of the main face material 2 are recessed so as to be in contact with the wood shaft material 3 adjacent in the length direction in order to strengthen the contact state with the wood shaft material 3 and not to generate a gap. Strips or ridges are formed only on one side.

上記構成の本面材２の形成は、以下のようにして行っている。
まず、２本の木軸材３を互いの凹条３２と凸条３１が適合するように並設して配置する。並設後には、木軸材３を固定して凸条側の側面から下穴４を長さ方向に対して直角方向に開孔する。下穴４の開孔位置は、木軸材３の側面の高さ寸法のほぼ中央であり、長さ方向に所定間隔を確保する。また、下穴４の開孔深さに関しては、少なくとも２本の木軸材３に跨る長さとする。この場合、２本の木軸材３を貫通しても良く、又は一部の下穴４については斜め方向に開孔しても良い（図示省略）。 The main face material 2 having the above-described configuration is formed as follows.
First, the two wooden shaft members 3 are arranged side by side so that the concave ridges 32 and the ridges 31 fit each other. After the juxtaposition, the wood shaft material 3 is fixed, and the pilot hole 4 is opened in a direction perpendicular to the length direction from the side surface on the ridge side. The opening position of the pilot hole 4 is substantially the center of the height dimension of the side surface of the wood shaft material 3, and ensures a predetermined interval in the length direction. Further, the opening depth of the prepared hole 4 is set to a length straddling at least two wood shaft members 3. In this case, the two wood shaft members 3 may be penetrated, or some of the pilot holes 4 may be opened in an oblique direction (not shown).

下穴４の開孔後には、各下穴位置に下穴径よりも若干拡径した締結線材５ａをそれぞれ貫入する。この締結線材５ａは木材用ビス又は木材用雄ネジであるため、その貫入によってネジ部５１が木軸材３と強固に結着する。締結線材５ａの長さは下穴深さとほぼ同じとしている。 After the pilot hole 4 is opened, the fastening wire 5a having a diameter slightly larger than the pilot hole diameter is inserted into each pilot hole position. Since the fastening wire 5a is a wood screw or a wood external screw, the threaded portion 51 is firmly bonded to the wood shaft material 3 by the penetration. The length of the fastening wire 5a is substantially the same as the prepared hole depth.

次に、一体化した２本の木軸材３、３の凸条側に新たな木軸材３を配置し、新たな木軸材３の凹条３２を一体化した木軸材３の凸条３１に適合させて側面どうしを当接させる。この状態で、締結線材５ａが貫入した位置と異なる位置に複数の下穴４を開孔する。所定数の下穴４の開孔の終了後には、この下穴４に締結線材５ａを貫入させていく。なお、一部の下穴深さについては、適宜に３本の木軸材３に跨るように設定しても良く、これに貫入する締結線材５ｂは当然に長く設定している。 Next, the new wood shaft material 3 is disposed on the protruding side of the two integrated wood shaft materials 3, 3, and the projection of the wood shaft material 3 in which the recess 32 of the new wood shaft material 3 is integrated. The side surfaces are brought into contact with each other in conformity with the article 31. In this state, a plurality of pilot holes 4 are opened at a position different from the position where the fastening wire 5a penetrates. After the opening of the predetermined number of prepared holes 4 is completed, the fastening wire 5a is inserted into the prepared holes 4. In addition, about some pilot hole depths, you may set suitably so that it may straddle the three wooden shaft materials 3, and the fastening wire 5b penetrated to this is naturally set long.

必要な締結線材５ａ、５ｂの貫入後は、新たな木軸材３の追加、貫入後の締結線材５ａ、５ｂに干渉しない位置への下穴４の開孔、この下穴４に対して適宜の締結線材５ａ、５ｂの貫入を繰り返し、所定本数の木軸材３から成る本面材２の形成が完了する。
［耐力壁の評価試験について］ After the necessary fastening wires 5a and 5b have penetrated, the addition of a new wood shaft material 3, the opening of the pilot hole 4 at a position not interfering with the fastening wires 5a and 5b after penetration, and the pilot hole 4 as appropriate. The fastening wires 5a and 5b are repeatedly penetrated to complete the formation of the main face material 2 composed of a predetermined number of wood shaft members 3.
[Evaluation test of bearing wall]

上記実施例の本面材２については、木軸材３を縦方向に立設させると共に、締結線材５ａ、５ｂの貫入態様を変えた耐力壁７、８を構築した。そして、耐力壁７、８において「耐力壁及びその倍率性能評価試験」を行ったところ良好な結果を得ている。 For the main face material 2 of the above-described embodiment, the load-bearing walls 7 and 8 were constructed in which the wood shaft material 3 was erected in the vertical direction and the penetration manner of the fastening wires 5a and 5b was changed.

本願発明は、木造軸組構法に用いる耐力面材と耐力面構造に関し、特に、構造用軸組材である木軸（柱又は間柱）と同様の木軸材を用いて形成した耐力面材と、これを用いた耐力面構造に関する。 The present invention relates to a load bearing surface material and a load bearing surface structure used in a wooden frame construction method , and in particular, a load bearing surface material formed using a tree shaft material similar to a wooden shaft (column or stud) which is a structural shaft assembly material; The present invention relates to a load bearing surface structure using the same.

木造軸組構法の耐力面の構築において、特に、耐力壁面の構築の場合、土台に所定間隔で柱を立設固定し、この柱間に筋交いを取り付けて壁の耐力を確保している。そして、この柱間に断熱材や防音材を充填させて後、合板やサイディングなどの面材を取り付ける工法を採っているのが一般的である。 In the construction of the load bearing surface of the wooden frame construction method , particularly in the case of building a load bearing wall, columns are erected and fixed at a predetermined interval on the base, and bracing is attached between the columns to ensure the strength of the wall. In general, a method of attaching a face material such as plywood or siding after filling the pillars with a heat insulating material or a soundproofing material is employed.

そこで、本願発明は、上記実情に鑑み発明されたものであり、簡易な構造でありながら強度が向上するだけでなく、長期経年による耐力低下を回避すると共に、複数の面材幅に迅速に対応できる耐力面材を提供するものである。さらに、これを用いて構築する木造軸組構法の耐力面構造を提供するものである。 Accordingly, the present invention has been invented in view of the above circumstances, and not only improves the strength while being a simple structure, but also avoids a decrease in yield strength due to long-term aging, and quickly responds to a plurality of face material widths. It provides a load-bearing face material that can be used. Furthermore, the present invention provides a load bearing surface structure of a wooden frame construction method constructed using this.

次に、本面材を用いた木造軸組構法の耐力面構造（以下、「本構造」と称する。）は、上記構成の耐力面材を、木造軸組構法の軸組材の間に取り付けたことを特徴としている。
ここで、木造軸組構法の軸組材としては、例えば、通し柱や間柱、土台、及び桁や胴差し等を示し、これらから成る軸組材に取り付ける場合、壁面を構成する耐力面構造となる。他にも、土台、大引きで成る軸組材に配置すれば床面を構成する耐力面構造となり、桁、梁で成る軸組材に配置すれば天井面を構成する耐力面構造となる。 Next, the load-bearing surface structure of the wooden frame construction method using the main face material (hereinafter referred to as “the present structure”) is constructed by attaching the load bearing face material having the above-described structure between the frame members of the wooden frame construction method. It is characterized by that.
Here, as the frame structure material of the wooden frame structure method , for example, through pillars, studs, foundations, girders, trunks, etc. are shown. . In addition, if it is arranged on a shaft assembly made of a base and a large pull, it becomes a load bearing surface structure that constitutes a floor surface, and if it is arranged on a shaft assembly made of a girder and a beam, it becomes a load bearing surface structure that constitutes a ceiling surface.

次に、本面材を用いた本構造は、木造軸組構法の軸組材を構成する木軸と同様の木軸材を用いて構成しているため、筋交いや断熱材や防音材や保温材等を省略することができ、
充填作業等の別作業をすることなく大工作業のみで構築できるため、作業効率と工期の短縮を図ることできる。特に、内装施工に関しては、木材の肌が表面に表れるので、これをそのまま内装仕上げとすることができ、材料削減や工期短縮、引いてはコスト削減にも資する。 Next, this structure using the main face material is constructed using the same wooden shaft material as the wooden shafts that make up the wooden frame construction method , so bracing, insulation, soundproofing materials, and heat insulation. Materials can be omitted,
Since it can be constructed only by carpenter work without performing separate work such as filling work, work efficiency and work period can be shortened. In particular, for interior construction, the skin of wood appears on the surface, so that it can be used as it is for interior finishing, which contributes to material reduction, shortening the construction period, and cost reduction.

さらに、本願発明は、壁面構築においては本面材を構成する木軸材を縦方向にして立設させているため、地震による影響が大きい横揺れへの抵抗力をより高めることでき、木造軸組構法としては強度がより向上した耐力壁を構築することができる。この耐力壁の強度向上によって耐力壁数を減少できるために設計自由度が増すことになり、例えば、住宅に大きな開口部を設けることが可能となる。加えて、接着剤を使用しないため、ハウスシック症候群のおそれもなく、住環境にやさしいものである。 Furthermore, in the present invention, since the wooden shaft material constituting the main surface material is set up in the vertical direction in the wall surface construction, it is possible to further increase the resistance to rolling, which is greatly affected by the earthquake, As a construction method, it is possible to construct a bearing wall with improved strength. Since the number of bearing walls can be reduced by improving the strength of the bearing walls, the degree of freedom in design increases. For example, a large opening can be provided in a house. In addition, since no adhesive is used, there is no risk of house sick syndrome and it is friendly to the living environment.

図１の図符号１は、本面材２を壁面として用いた本構造である。本構造１は、基礎９１の上面に載置した土台９２に所定の離隔距離で２本の柱９３を立設し、柱間の上部には桁９４を跨ぐように配設して木造軸組構法の軸組材９を成し、この軸組材内に本面材２を固定して構成している。 Reference numeral 1 in FIG. 1 is a main structure using the main face material 2 as a wall surface. In this structure 1, two pillars 93 are erected at a predetermined separation distance on a base 92 placed on the upper surface of a foundation 91, and arranged between the pillars so as to straddle the girders 94. A shaft assembly material 9 is constructed , and the main surface material 2 is fixed in the shaft assembly material.

なお、本面材２は、実施例のように壁面に限定するものでなく、取り付ける木造軸組構法の軸組材９によっては、壁面の他、床面や天井面として構成するようにしても良い。 The face material 2 is not limited to the wall surface as in the embodiment, and may be configured as a floor surface or a ceiling surface in addition to the wall surface depending on the frame material 9 of the wooden frame construction method to be attached. good.

すなわち、同一横断面形の角柱木軸材の複数本を、それぞれ側面当接させて面一状に配置して固定一体化して成り、該固定一体化が、２本又は３本の前記木軸材間に跨る長さの木材用ビスをねじ込み締結すると共に、該ねじ込み締結箇所を、上記耐力面材の適宜の複数箇所に分散配置して行っていることを特徴としている。なお、上記木材用ビスは、木材用雄ネジに変更しても良い。 That is, a plurality of prismatic wooden shafts having the same cross-sectional shape are arranged so as to be flush with each other by abutting the side surfaces, and the fixed integration is composed of two or three wooden shafts. It is characterized in that a screw for wood having a length straddling between materials is screwed and fastened, and the screwed fastening locations are distributed and arranged at a plurality of appropriate locations on the load bearing face material. The wood screw may be changed to a wood male screw.

また、木材用ビスのねじ込み方向は、木軸材の長さ方向に対して直角方向、斜め方向、又はこれらの組合せを採用したことを特徴としている。 In addition, the screwing direction of the wood screw is characterized by adopting a direction perpendicular to the length direction of the wood shaft material, an oblique direction, or a combination thereof.

上記角柱木軸材の側面当接においては、側面に形成した凹条又は凸条の適合によるものであることを特徴としている。凹条及び凸条は、側面の一部又は全面に渡って形成しても良い。 The side contact of the prismatic wooden shaft is characterized by conforming a concave line or a convex line formed on the side surface. The concave stripe and the convex stripe may be formed over a part of the side surface or the entire surface.

また、前記凹凸条の当接適合が、角柱木軸材の面取り成形に適合する凹条成形によるものでも良い。具体的には、一方の角柱木軸材を面取り成形して側面全体を凸条形とし、他方の適合側は上記面取り部に適合する凹条を側面全体に成形するものである。 Moreover, the contact conformity of the said uneven | corrugated strip may be based on the concave strip shaping | molding suitable for the chamfering shaping | molding of a prismatic wooden shaft. Specifically, one of the prismatic wood shaft member chamfered forming the entire side and convex shape, the other fit side is intended to mold the entire side surface of the concave conforming to the chamfer.

次に、本面材を用いた木造軸組構法の耐力面構造（以下、「本構造」と称する。）は、上記構成の耐力面材を、木造軸組構法の軸組材の間に取り付けて耐力壁面としたことを特徴としている。ここで、木造軸組構法の軸組材としては、例えば、通し柱や間柱、土台、及び桁や胴差し等を示し、これらから成る軸組材に取り付け固定する。その場合、木軸材を、縦方向にして土台に立設させて木造軸組の柱間又は間柱間に取付け固定すれば、耐力壁面を構成する耐力面構造となる。他にも、耐力面材を取り付ける部位が、土台、大引きであれば床面を構成する耐力面構造となり、桁、梁であれば天井面を構成する耐力面構造となる。 Next, the load-bearing surface structure of the wooden frame construction method using the main face material (hereinafter referred to as “the present structure”) is constructed by attaching the load bearing face material having the above-described structure between the frame members of the wooden frame construction method. It is characterized by having a load bearing wall . Here, as a shaft assembly material of the wooden frame construction method, for example, a through column, a stud, a base, a girder, a body insertion, and the like are shown, and they are attached and fixed to the shaft assembly composed of these . In that case, if the wooden shaft material is installed in the vertical direction and is erected on the base and attached and fixed between the columns of the wooden frame or between the columns, a load bearing surface structure constituting a load bearing wall is obtained. Additional sites for attaching the load-bearing surface material, foundation, if large pull becomes load bearing surface structure forming the floor surface, digits, the load bearing surface structure forming the ceiling surface, if the beams.

また、本面材を構成する角柱木軸材の断面形を、取付け固定する部位の軸組材の木軸と同一横断面形としても良い。この場合、本面材と軸組材間には凹凸面が生じず、美観を確保できると共に余計な引っ掛かりもないため安全面も向上する。 Further, the cross-sectional shape of the prismatic wood shaft material constituting the face material may be the same cross-sectional shape as the wood shaft of the shaft assembly material of the portion to be attached and fixed . In this case, an uneven surface is not formed between the main face material and the shaft assembly material, and an aesthetic appearance can be ensured, and safety is improved because there is no extra catch.

本面材は上記構成を採用することにより、複数の角柱木軸材間に跨るようにねじ込み締結させた複数の木材用ビスによって木軸材の連結状態を高めることができる。本面材は、所定の外力が繰り返し作用しても複数箇所に配設した各木材用ビスが、隣接する角柱木軸材どうしと個別的に結着しているため、面材の耐力低下を招くことはない。また、長期経年の作用によって生じる応力緩和やクリープは、各木材用ビス限りのものであって、かつその方向性が区々であるため、面材としての耐力を安定的に維持することができる。 By adopting the above-described configuration, the present face material can enhance the connection state of the wood shaft materials by a plurality of wood screws screwed and fastened so as to straddle between the plurality of prismatic wood shaft materials. Even if a predetermined external force is repeatedly applied, this wood face material is used to connect each of the wood screws arranged at multiple locations individually to adjacent prismatic wood shafts, thus reducing the strength of the face material. There is no invitation. In addition, stress relaxation and creep caused by long-term aging are limited to the screws for each wood , and the directionality varies, so the proof stress as a face material can be stably maintained. .

また、木材用ビスのねじ込み方向を直角方向だけでなく斜め方向にして組み合わせた場合は、面材へ作用する外力を木材用ビスのねじ込み方向に適宜に分散することができるため、耐力面材をより強固に構築することかできる。 In addition, when the screwing direction of the wood screw is combined in an oblique direction as well as a right angle direction, the external force acting on the face material can be appropriately dispersed in the screwing direction of the wood screw. Can be built more firmly.

さらに、角柱木軸材の側面当接を、凹条又は凸条の適合としているため、木軸材どうしの当接時や木材用ビスのねじ込み締結による位置ズレが抑制され、面材の面を一にした安定品質の耐力面材を形成することができる。 Furthermore, because the side contact of the prismatic wooden shaft material is adapted to the concave or convex shape, positional displacement due to the contact between the wooden shaft materials and screwing of the screws for wood is suppressed, and the surface of the surface material is reduced. It is possible to form a single bearing surface with stable quality.

また、軸組材を構成する木軸と同一横断面形（同一寸法角）の角柱木軸材を用いて耐力面材を形成した場合は、壁面や床面や天井面の内装面の工事を省略することができる。これにより、当該工事費の削減が図れるだけでなく、内装及び外装の美観向上にも寄与する。 In addition, when a load bearing surface is formed using a prismatic wooden shaft that has the same cross-sectional shape (same dimension angle) as the wooden shaft that constitutes the shaft assembly, the interior surface of the wall surface, floor surface, or ceiling surface must be constructed. Can be omitted. This not only reduces the construction cost, but also contributes to improving the aesthetics of the interior and exterior.
