Description
本発明は木製筒状部材、及びこれを用いて形成された構造物に関する。特に長尺な木材の長さ方向に貫通する貫通孔を設けた木製筒状部材、及びこれを用いて形成された構造物に関する。
The present invention relates to a wooden tubular member and a structure formed using the same. In particular, the present invention relates to a wooden cylindrical member provided with a through-hole penetrating in the length direction of a long wood, and a structure formed using the same.
従来から、木材は加工が容易であることから、建築材料等として広く利用されている。特に十分に乾燥させた木材は、寸法変化の少ない優れた建築材料として長期的に使用することができる。しかしながら、木材は芯があることから、その乾燥収縮により、狂い、曲がり、割れなども少なからず発生してしまう。 Conventionally, wood has been widely used as a building material because it is easy to process. In particular, sufficiently dried wood can be used for a long time as an excellent building material with little dimensional change. However, since wood has a core, the dry shrinkage causes a lot of craving, bending, and cracking.
そこで従前においては、当該木材の芯を刳り貫く技術もいくつか提案されている。例えば特許文献１（実開昭６３−１７７５１６号公報）では、在来建築木材の外観の美を損なうことなく、ひびわれや狂いを防ぐために、柱の芯とその周囲をくりぬき貫通させ、その部分に木や鉄パイプを埋め込んだ柱を提案している。 Therefore, several techniques have been proposed in the past to penetrate the wood core. For example, in Patent Document 1 (Japanese Utility Model Publication No. 63-177516), in order to prevent cracking and distorting without impairing the beauty of the appearance of conventional building wood, the core of the pillar and its surroundings are perforated and penetrated into that part. Proposes pillars with embedded wood and steel pipes.
また、建築などに使用される木材、特に杉、檜等は、本来的に軟質材であることから堅牢度が低く、これよりその使用可能な範囲については自ずと制限が存在していた。更に、杉、檜等の成育過程において除去される間伐材は小径木であり、また、極めて柔らかく湾曲していることが多いことから、当該間伐材を建築材料(特に柱等)として使用できるものではなかった。 In addition, wood used for construction, in particular cedar, straw, etc., is inherently a soft material, so it has low fastness, and thus there is a limit to the usable range. Furthermore, thinned wood that is removed in the growing process of cedars, firewood, etc. is small-diameter wood, and because it is often extremely soft and curved, it can be used as building material (especially pillars, etc.) It wasn't.
そこで従前においては、当該木材を補強する為に金属などの骨材を使用する技術も提案されている。例えば特許文献２（実開昭６３−５４７１５号公報）では、梁、桁、柱等の長い木製構造部材に関し、特に内部に金属製の骨材を入れ補強し、強度を飛躍的に高め、木材の節約や軽量化と共に配線、配管などにも使用できるようにするべく、木材本体を縦に少なくとも２分割し、それらの分割面に溝を形成させ、該溝に金属製形鋼又はパイプ等の骨材を嵌合し、分割した木材本体を骨材と共に分割面で接合した木製構造部材が提案されている。 Therefore, in the past, a technique of using an aggregate such as metal to reinforce the wood has been proposed. For example, Patent Document 2 (Japanese Utility Model Publication No. 63-54715) relates to long wooden structural members such as beams, girders, pillars and the like, in particular, by reinforcing a metal aggregate inside to reinforce the strength. In order to be able to be used for wiring, piping, etc. as well as saving and reducing weight, the wood body is divided into at least two parts vertically and grooves are formed on the divided surfaces, and metal grooves or pipes are formed in the grooves. There has been proposed a wooden structural member in which an aggregate is fitted and a divided wood body is joined together with the aggregate on a divided surface.
そして従前においては、木造建築に関し、柱状体の連結構造についても検討されている。例えば特許文献３（特開平６−１１７０２１号公報）では、従来の柱状体の連結はかすがいや羽子板ボルトで固定するため、連結すると連結が緩んだ場合や立てり等の調整が不可能で融通性に欠けるところがあったことに鑑みて、連結される柱状体の鋼性を増し、全体が一体化した構造体とすると共に、筋交いとして使用もでき、又ワイヤー固定Ｌ型レベル金物の取り付けで建物の立てりを見ることができ、かつ、運搬も容易にした木造建築に於ける柱状体の連結構造を提案している。即ちこの文献では、連結する柱状体に連結方向に貫通孔を穿設し、該貫通孔にパイプが嵌入されると共に、パイプ内にワイヤーが挿通され、該ワイヤーを緊締することにより柱状体の連結を強固にする木造建築に於ける柱状体の連結構造を提案している。 In the past, with regard to wooden construction, the connection structure of columnar bodies has also been studied. For example, in Patent Document 3 (Japanese Patent Laid-Open No. 6-117021), the connection of the conventional columnar bodies is fixed with a shading or a wing plate bolt. In view of the lack of, there is an increase in the steel properties of the connected columnar bodies, and the entire structure is integrated, and can also be used as a brace. We propose a connecting structure of columnar bodies in a wooden building that allows you to see the stand and to carry it easily. That is, in this document, a through hole is formed in a connecting direction in a connecting columnar body, a pipe is inserted into the through hole, a wire is inserted into the pipe, and the columnar body is connected by tightening the wire. It proposes a connecting structure of columnar bodies in wooden construction that strengthens the structure.
前述の通り、従前においても木材の長さ方向に貫通する孔部を形成した木製筒状部材はいくつか提案されていた。しかしながら、従前において提供されている木製筒状部材は、その端部が切り落とされた構造となっていたことから、これを使用する場合には、別途結合部材が必要であった。 As described above, several wooden tubular members in which a hole penetrating in the length direction of the wood has been proposed. However, since the wooden cylindrical member provided in the past has a structure in which the end portion is cut off, a separate connecting member is required when using this.
そこで本発明は、木製筒状部材だけでも連結することができるようにした木製筒状部材を提供することを課題とする。
Then, this invention makes it a subject to provide the wooden cylindrical member which enabled it to connect only with a wooden cylindrical member.

Further, in addition to the connection structure portion being formed at any one end in the length direction, the connection structure portion may be formed on both sides in the length direction. The through hole may be formed so as to penetrate an eccentric position in addition to penetrating the center of the long wood. Furthermore, the number of the through holes is not limited to one, and two or more through holes may penetrate in the length direction. Furthermore, the through-hole may have a circular, cross-sectional shape, a triangle, a quadrangle, or other shapes. Further, the inner diameter and the cross-sectional shape of the through hole are the same in the length direction of the long wood, and the size of the inner diameter at an arbitrary place can be changed, or the cross-sectional shape at an arbitrary place can be changed.
かかる木製筒状部材を使用することにより、少なくとも何れかの端面に形成された連結構造部により、他の部材との連結を行うことができる。これにより、木製筒状部材だけでも連結することができるようにした木製筒状部材を提供することができる。ただし、この連結構造部による連結部分には、補強などの要請がある場合には、他の連結具（連結金具など）を使用することもできる。 By using such a wooden tubular member, it is possible to connect to another member by a connecting structure portion formed on at least one of the end faces. Thereby, the wooden cylindrical member which enabled it to connect only with a wooden cylindrical member can be provided. However, when there is a demand for reinforcement or the like in the connecting portion by the connecting structure portion, another connecting tool (such as a connecting metal fitting) can be used.
また、上記木製筒状部材において、前記貫通孔は、他の部材と連結するための連結構造部の凹凸形状部分を避けた位置に開口するように形成する他、当該連結構造部（凹凸形成部分）も貫通するように形成することができる。 Further, in the wooden tubular member, the through hole is formed so as to open at a position avoiding the uneven shape portion of the connection structure portion for connecting to another member, and the connection structure portion (the uneven formation portion). ) Can also be formed.

It can be set as the filling member which was excellent in at least any of the property. By inserting the reinforcing member, the strength of the wooden tubular member can be increased. Moreover, the characteristic of a wooden cylindrical member can be improved by interpolating the said filling member according to the characteristic of the said filling member. Furthermore, the members to be inserted into the through-holes are selected according to the purpose, such as metal pipes such as iron pipe, H steel, angle steel, channel steel, joist steel, lip groove steel, and other wood and resin.

The structure formed can be provided.
以下、図面を参照しながら、本実施の形態にかかる木製筒状部材10と、これを用いて構築した構造物30を具体的に説明する。 Hereinafter, the wooden cylindrical member 10 according to the present embodiment and the structure 30 constructed using the same will be specifically described with reference to the drawings.
図１は第１の実施の形態にかかる木製筒状部材10を示す六面図であり、（Ａ）正面図、（Ｂ）右側面図、（Ｃ）左側面図、（Ｄ）背面図、（Ｅ）平面図、（Ｆ）底面図である。この実施の形態にかかる木製筒状部材10は、角材11を用いて形成されており、その長さ方向の端部には、段状に切り欠いた連結構造部12を形成している。そして長さ方向に貫通する貫通孔13が穿孔されており、当該貫通孔13は、前記連結構造部12を通って形成されている。ただし、貫通孔13は、前記連結構造部12を外れた位置に形成することもでき、当該貫通孔13が、連結構造部12を形成した面（端面など）に１又は２以上開口するように形成しても良い。 FIG. 1 is a six-sided view showing a wooden tubular member 10 according to the first embodiment, (A) front view, (B) right side view, (C) left side view, (D) rear view, (E) Top view, (F) Bottom view. A wooden cylindrical member 10 according to this embodiment is formed using a square member 11, and a connecting structure portion 12 cut out in a step shape is formed at an end portion in the length direction. A through hole 13 penetrating in the length direction is perforated, and the through hole 13 is formed through the connecting structure portion 12. However, the through hole 13 can also be formed at a position away from the connection structure portion 12, and the through hole 13 opens one or more on the surface (end surface or the like) where the connection structure portion 12 is formed. It may be formed.
特に本実施の形態において、当該連結構造部12は、段状に切り欠いた構造（アイジャクリ構造）として形成しているが、その他にもホゾ構造、寄席ホゾ構造、短ホゾ構造、鎌継手構造、アリ継手構造、仕口アリ構造、胴差ホゾ構造、横差しホゾ構造、茶臼構造などのように、凹凸構造部からなり、木材同士を連結する結合構造によって形成することができる。また、本実施の形態において、当該貫通孔13は断面形状を円形に形成しているが、矩形など任意の形状であって良い。またこの貫通孔13の開口径は任意であって良く、当該木製筒状部材10に要求される強度や、当該貫通孔13に内挿する部材の大きさ等によって適宜調整することができる。 In particular, in the present embodiment, the connection structure portion 12 is formed as a stepped structure (eye-jackle structure), but in addition, a side-by-side structure, a side-by-side structure, a short side-by-side structure, a sickle joint structure, It can be formed by a joint structure composed of a concavo-convex structure portion, such as an ant joint structure, a joint ant structure, a body difference side structure, a transverse side structure, a tea mill structure, etc., and connects woods together. In the present embodiment, the through-hole 13 has a circular cross-sectional shape, but may have an arbitrary shape such as a rectangle. The opening diameter of the through hole 13 may be arbitrary and can be appropriately adjusted depending on the strength required for the wooden tubular member 10, the size of the member inserted into the through hole 13, and the like.
以上のように形成した木製筒状部材10では、中心部分を刳り貫いていることから、軽量化を図ることができ、更に当該木材の中心部に穿った貫通孔13により、当該木材の割れや変形などを解消することができる。また当該貫通孔13は配線等を通すための通路として利用することもでき、これにより配線を露出させることなく、構造部内に設置することができる。 In the wooden cylindrical member 10 formed as described above, since the center portion is pierced through, the weight can be reduced, and further, through the through-hole 13 drilled in the center portion of the wood, Deformation etc. can be eliminated. The through-hole 13 can also be used as a passage through which wiring or the like passes, and thus can be installed in the structure without exposing the wiring.
そして上記木製筒状部材10は貫通孔13を備えることから、当該貫通孔13には、当該角材11（即ち、長尺な木材）よりも、圧縮強度、引張強度、曲げ強度およびせん断強度の少なくとも何れかが大きい補強部材14、及び／又は吸湿性、保温性および防錆性の少なくとも何れかが優れた充填部材を内挿することができる。そして、これらを内挿することにより、簡易に複合材料を形成することができ、これを建築用途で建築材料（例えば柱や梁などの柱状部材）として使用することもできる。 Since the wooden tubular member 10 includes the through-hole 13, the through-hole 13 has at least compressive strength, tensile strength, bending strength, and shear strength as compared with the square member 11 (that is, long wood). It is possible to interpolate a reinforcing member 14 that is large and / or a filling member that is excellent in at least one of hygroscopicity, heat retention and rust prevention. By interpolating these, a composite material can be easily formed, and this can be used as a building material (for example, a columnar member such as a column or a beam) in a building application.
図２は、上記貫通孔13に補強部材14を内挿する状態を示す工程図であり、（Ａ）分解図、（Ｂ）連結状態図である。この図２に示すように、前記貫通孔13を有する木製筒状部材10を連結する際には、当該木製筒状部材10の連結部分をアイジャクリ組み（相欠き組）によって連結し、この連結部分を貫通して補強部材14が存在するように構成することができる。これにより当該連結部の結合強度を高めることができ、建築物に使用した場合には、構造強度を高めることができる。これは、本実施の形態にかかる木製筒状部材10が、長さ方向の端部に結合構造が形成され、且つ前記貫通孔13が当該結合構造を貫通して形成されていることによるものである。即ち、このように形成した木製筒状部材10では、木材同士の連結部分における強度を補強部材14によって補強し、補強部材14同士では連結が困難な点を木材の連結構造部12によって補強することができる。 FIG. 2 is a process diagram showing a state in which the reinforcing member 14 is inserted into the through-hole 13, and is an (A) exploded view and a (B) connected state diagram. As shown in FIG. 2, when connecting the wooden cylindrical member 10 having the through-hole 13, the connecting portion of the wooden cylindrical member 10 is connected by an eye-jaw assembly (phase missing assembly). The reinforcing member 14 can be formed so as to pass through. Thereby, the joint strength of the said connection part can be raised, and when used for a building, structural strength can be raised. This is because the wooden cylindrical member 10 according to the present embodiment has a coupling structure formed at the end in the length direction, and the through hole 13 is formed through the coupling structure. is there. That is, with the wooden tubular member 10 formed in this way, the strength at the connecting portion between the timbers is reinforced by the reinforcing member 14, and the point that is difficult to connect between the reinforcing members 14 is reinforced by the connecting structure portion 12 of timber. Can do.
本実施の形態にかかる木製筒状部材10では、貫通孔13に補強部材14を内挿していることから、当該貫通孔13に内挿された補強部材14によって、当該木製筒状部材10自体の強度を高めることができる。よって、例えば間伐材などのように、木材の強度を特定できない場合であっても、当該貫通孔13に内挿した補強部材14に基づく強度を得ることができる。よって、本実施の形態にかかる木製筒状部材10により、間伐材の有効活用を実現できる。 In the wooden cylindrical member 10 according to the present embodiment, since the reinforcing member 14 is inserted into the through hole 13, the wooden cylindrical member 10 itself is inserted by the reinforcing member 14 inserted into the through hole 13. Strength can be increased. Therefore, for example, even when the strength of wood cannot be specified, such as thinned wood, strength based on the reinforcing member 14 inserted into the through hole 13 can be obtained. Therefore, effective utilization of the thinned wood can be realized by the wooden tubular member 10 according to the present embodiment.
上記貫通孔13に内挿する補強部材14は、鉄パイプを使用する他、Ｈ鋼、アングル鋼、他の木材、樹脂、セラミックなど、木材よりも、圧縮強度、引張強度、曲げ強度およびせん断強度の少なくとも何れかが大きい部材であれば使用できる。特に、鉄パイプであれば、貫通した中空部を有することから、この内部空間に配線などを通すこともできる。前記貫通孔13の断面形状と、当該貫通孔13に通される補強部材14の断面形状とは、必ずしも同一又は相似形である必要はなく、例えば貫通孔13を丸孔として、これにＨ鋼などを挿入することもできる。 The reinforcing member 14 to be inserted into the through hole 13 uses an iron pipe, H steel, angle steel, other wood, resin, ceramic, etc., more compressive strength, tensile strength, bending strength and shear strength than wood. Any member can be used as long as at least one of them is large. In particular, since an iron pipe has a hollow portion that penetrates, it is possible to pass wiring or the like through this internal space. The cross-sectional shape of the through-hole 13 and the cross-sectional shape of the reinforcing member 14 passed through the through-hole 13 do not necessarily have to be the same or similar. Etc. can also be inserted.
また、前記木製筒状部材10の連結に際しては、その貫通孔13内に予め補強部材14を内挿しておき、これを連結する他、木製筒状部材10を連結した後に、補強部材14を装填することもできる。何れの工法を採用するかは、部材の長さや現場状況に応じて適宜選択することができる。 When connecting the wooden tubular member 10, the reinforcing member 14 is inserted in the through-hole 13 in advance, and in addition to connecting the wooden cylindrical member 10, the reinforcing member 14 is loaded. You can also Which method is used can be appropriately selected according to the length of the member and the situation at the site.
前記木材は、必ずしも無垢の木材である必要はなく、その他にも、集積材やコルク材等のように木材を加工して形成されたものや、或いは樹脂材料であっても良い。また必ずしも柱状に形成される必要はなく、その他にも、板状又はブロック状であっても良い。ただし長さ方向の少なくとも何れかの端部には、前記した連結構造部12を設ける必要がある。当該連結構造部12により、構造物30の構築を円滑に行うためである。 The wood is not necessarily solid wood, but may be a material formed by processing wood such as an accumulation material or a cork material, or a resin material. Moreover, it does not necessarily need to be formed in a columnar shape, and may be a plate shape or a block shape. However, it is necessary to provide the connecting structure portion 12 described above at least at one end in the length direction. This is because the structure 30 is smoothly constructed by the connection structure portion 12.
また、前記貫通孔13には、補強部材14とともに、又は補強部材14に代えて、吸湿性、保温性および防錆性の少なくとも何れかが優れた充填部材を充填することもできる。例えば、防腐剤を充填して木材の腐食を予防することができ、更にゼオライトや木炭を充填して、吸湿を図ることもできる。 Further, the through-hole 13 can be filled with a filling member excellent in at least one of hygroscopicity, heat retention, and rust prevention, together with the reinforcing member 14 or in place of the reinforcing member 14. For example, it is possible to prevent corrosion of wood by filling with a preservative, and to absorb moisture by filling with zeolite or charcoal.
以上のように形成した木製筒状部材10（又は複合材料）は、他の部材と連結して使用することができる。図３は第二の実施の形態にかかる木製筒状部材10を示す（Ａ）要部分解斜視図、（Ｂ）組み立て状態を示す斜視図である。 The wooden cylindrical member 10 (or composite material) formed as described above can be used by being connected to other members. FIG. 3A is an exploded perspective view of a main part showing a wooden cylindrical member 10 according to the second embodiment, and FIG. 3B is a perspective view showing an assembled state.
この図３に示す木製筒状部材10は、長尺な角材11（柱状部材）であって、その長さ方向端部に他の部材との連結を実現するための連結構造部12が形成されており、且つ当該角材11の中心部分に、長さ方向に貫通する貫通孔13を形成している。 特に本実施の形態において、当該木製筒状部材10は、その端部に形成される結合構造がホゾの例を示しているが、ホゾ以外であっても、前述したような様々な結合構造とすることもできる。 The wooden tubular member 10 shown in FIG. 3 is a long square member 11 (columnar member), and a connecting structure portion 12 for realizing connection with other members is formed at the end in the length direction. In addition, a through hole 13 penetrating in the length direction is formed in the central portion of the square member 11. In particular, in the present embodiment, the wooden cylindrical member 10 shows an example in which the coupling structure formed at the end portion thereof is a tenon. You can also
特にこの第二の実施の形態にかかる木製筒状部材10は、連結構造として形成されているホゾ部分にも貫通孔13が存在している。かかる貫通孔13の形成により、ホゾ部分自体は強度が弱まることも危惧されるが、本実施の形態では、当該ホゾ部分にも補強部材14が存在することから、むしろホゾ部分における連結構造自体が補強されたものとなっている。この実施の形態における木製筒状部材10は、連結構造を形成した後に、当該角材11の中心を長さ方向に貫通するように刳り貫くことにより形成することができる。そしてこの図３に示したような連結構造は、他の部材との連結に使用される。 In particular, in the wooden tubular member 10 according to the second embodiment, the through hole 13 is also present in the side portion formed as a connecting structure. The formation of the through-hole 13 may cause the strength of the hoso portion itself to be weakened. However, in this embodiment, since the reinforcing member 14 is also present in the hoso portion, the connecting structure itself in the hoso portion is rather reinforced. It has been made. The wooden tubular member 10 in this embodiment can be formed by punching through the center of the square member 11 in the length direction after forming the connecting structure. The connection structure as shown in FIG. 3 is used for connection with other members.
図４は、木材の一端側に、連結構造部12として短ホゾ構造を形成し、且つ当該連結構造部12を貫通するようにして、長さ方向に貫通する貫通孔13を形成し、当該貫通孔13には単管パイプ（連結構造部12）を内挿して形成した木製筒状部材10と、当該木製筒状部材10と連結する他の部材20との連結状態を示している。この実施の形態にかかる他の部材20は、その側面に当該木製筒状部材10を連結するように構成しており、当該連結部分には、ホゾ穴21を形成している。特に本実施の形態において、前記単管パイプからなる補強部材14の外径は、連結構造部12である短ホゾの短辺よりも大きく、はみ出していることから、前記ホゾ穴21には当該連結構造部12が挿入可能なように、中心部分を広げた形状に形成されている。 FIG. 4 shows that a short side structure is formed as a connecting structure portion 12 on one end side of the wood, and a through-hole 13 that penetrates in the length direction is formed so as to penetrate the connecting structure portion 12. The hole 13 shows a connection state between a wooden tubular member 10 formed by inserting a single pipe (connecting structure portion 12) and another member 20 connected to the wooden tubular member 10. The other member 20 according to this embodiment is configured so as to connect the wooden tubular member 10 to a side surface thereof, and a side hole 21 is formed in the connection portion. In particular, in the present embodiment, the outer diameter of the reinforcing member 14 made of the single pipe pipe is larger than the short side of the short side that is the connecting structure portion 12 and protrudes, so that the connecting hole 21 is connected to the connecting hole 21. The center portion is formed in a shape that allows the structure portion 12 to be inserted.
このような構成により、前記木製筒状部材10と、他の部材20との連結部には補強部材14が存在することができ、これにより当該連結部分の強度を高めることができる。 With such a configuration, the reinforcing member 14 can be present at the connecting portion between the wooden tubular member 10 and the other member 20, thereby increasing the strength of the connecting portion.
図５は図４に示した連結部に関連し、他の部材20に対して２つの木製筒状部材10を連結した状態を示す縦断面図である。この図に示すように、他の部材20に連結する木製筒状部材同士の少なくとも連結構造部12には、１つの補強部材14が貫通して存在することが望ましい。本実施の形態では１つの木製筒状部材10の中心を貫通し、他の部材20における連結部（ホゾ穴21）を貫通し、そして更に他の木製筒状部材10の中心を貫通するようにパイプ部材からなる補強部材14を存在させていることから、２つの木製筒状部材10と１つの他の部材21との連結を確実に行うことができる。 FIG. 5 is a longitudinal sectional view showing a state in which two wooden cylindrical members 10 are connected to another member 20 in relation to the connecting portion shown in FIG. As shown in this figure, it is desirable that one reinforcing member 14 penetrates through at least the connection structure portion 12 of the wooden cylindrical members connected to the other member 20. In the present embodiment, it passes through the center of one wooden cylindrical member 10, passes through the connecting portion (side hole 21) in the other member 20, and further passes through the center of the other wooden cylindrical member 10. Since the reinforcing member 14 made of a pipe member is present, the two wooden tubular members 10 and one other member 21 can be reliably connected.
以上の実施の形態に示した木製筒状部材10において、貫通孔13に補強部材14や充填部材を内挿する場合には、当該補強部材14や充填部材は貫通孔内に嵌入もしくは遊嵌する他、貫通孔13の内面と補強部材14や充填部材の外面との間に接着剤や樹脂などを存在させて、両者を一体化することもできる。特に補強部材14を木製筒状部材10の貫通孔内に一体化した場合には、連結部における強度や、当該木製筒状部材10自体（即ち複合材料）の強度を高めることができる。 In the wooden tubular member 10 shown in the above embodiment, when the reinforcing member 14 or the filling member is inserted into the through hole 13, the reinforcing member 14 or the filling member is fitted or loosely fitted into the through hole. In addition, an adhesive, a resin, or the like may be present between the inner surface of the through-hole 13 and the outer surface of the reinforcing member 14 or the filling member to integrate them. In particular, when the reinforcing member 14 is integrated into the through hole of the wooden cylindrical member 10, the strength at the connecting portion and the strength of the wooden cylindrical member 10 itself (ie, the composite material) can be increased.
図６は上記の実施の形態にかかる木製筒状部材10を用いて構築した構造物30を示す部分側面図である。特に本実施の形態では当該構造物30として、家屋などの建築物を例に説明する。この実施の形態にかかる構造物30において、前記木製筒状部材10は、通し柱38と、桁又は梁39に使用されている。 FIG. 6 is a partial side view showing the structure 30 constructed using the wooden tubular member 10 according to the above embodiment.

The wooden tubular member 10 according to the above embodiment is used for the beam or beam 39, and the reinforcing member 14 is inserted into the through hole 13 extending in the length direction. Therefore, by connecting the reinforcing member 14 extending from the beam or beam 39 to the reinforcing member 14 of the through pillar 38, the strength at the connecting portion can be increased. In the present embodiment, the girder or beam 39 is fixed to the through column 38 with the vertical pulling bolt 33, and the reinforcing members are connected to each other by the joint fitting 15 formed in a “T” shape, and the strength at the connecting portion is increased. It is increasing.
このように、建築物（構造物30）と基礎32、及び通し柱38と桁又は梁39との連結部分には、補強部材14を存在させることにより、地震や台風などにより、建築物に外力が作用して倒壊するような場合であっても、当該倒壊の恐れを極力減じると共に、当該補強部材14の曲げ耐力により、座屈の時間を確保することができる。 In this way, external force is applied to the building due to an earthquake, typhoon, etc. by the presence of the reinforcing member 14 at the connecting portion between the building (structure 30) and the foundation 32, and the through pillar 38 and the beam or beam 39. Even in the case of the collapse due to the action, the risk of the collapse can be reduced as much as possible, and the bending strength of the reinforcing member 14 can ensure the buckling time.

そして図７は、前記ジョイント金具を用いた連結構造部12を示す斜視図であり、図８は当該ジョイント金具を用いた連結工程を示す縦断面図である。これらの図に示すように、本実施の形態にかかる木製筒状部材10において、貫通孔13を通る補強部材同士は、Ｔ字状のジョイント金具15などを使用することにより、３方向に連結することができる。更に当該ジョイント金具15の構造によっては、４方向に連結することも可能である。 FIG. 7 is a perspective view showing the connecting structure portion 12 using the joint fitting, and FIG. 8 is a longitudinal sectional view showing the connecting step using the joint fitting. As shown in these drawings, in the wooden tubular member 10 according to the present embodiment, the reinforcing members passing through the through holes 13 are connected in three directions by using a T-shaped joint fitting 15 or the like. be able to. Further, depending on the structure of the joint fitting 15, it is possible to connect in four directions.
特に、当該ジョイント金具15を用いて補強部材同士を連結する場合には、当該連結構造部12による連結部分から外れた位置に、ジョイント金具15と補強部材14との連結部分が存在することが望ましい。このように形成すれば、ジョイント金具自体が補強部材14として機能し、当該連結部分の強度を高めることができる。即ち、木材と補強金具とにより相乗的な強度が得られる。
In particular, when the reinforcing members are connected to each other using the joint fitting 15, it is desirable that a connecting portion between the joint fitting 15 and the reinforcing member 14 exists at a position deviated from the connecting portion by the connecting structure portion 12. . If formed in this way, the joint fitting itself functions as the reinforcing member 14, and the strength of the connecting portion can be increased.
