Description

本発明は、各種木構造において、様々な方向に伸びる複数の部材を一括して一体化できる連結具と、この連結具を用いた屋根構造に関する。 The present invention relates to a connector that can integrate together a plurality of members extending in various directions in various tree structures, and a roof structure using the connector.

木造建築で広く普及している軸組構法では、強度を向上するため、筋交いなどの斜材を配置することが多い。また近年は、公共施設などを中心に斬新なデザインの木造建築が施工されるようになり、多数の部材を様々な交角で配置することもある。このように木造建築においては、部材同士を直角ではなく斜方向に連結することも多いが、その施工作業は複雑化しやすい上、強度の確保も難しい。そのため以前から様々な技術開発が進められており、例として後記特許文献が挙げられる。 In the frame construction method widely used in wooden construction, diagonal materials such as braces are often arranged in order to improve the strength. In recent years, wooden buildings with novel designs have been constructed mainly in public facilities, and many members may be arranged at various intersections. In this way, in wooden construction, members are often connected obliquely rather than at right angles, but the construction work is easily complicated and it is difficult to ensure strength. For this reason, various technological developments have been undertaken since before, and the following patent documents can be cited as examples.

特許文献１では、構成が簡素で施工費の低減を図ることのできる木材の接合構造が開示されている。この接合構造は、木材に埋め込む全螺子ボルトと、円環部材を用いており、円環部材は、文字通りの円筒状で、二部材の境界に配置され、また全螺子ボルトは、連結される個々の部材に埋め込むが、その一端は部材から突出させる。そして、部材から突出する全螺子ボルトを円環部材の挿通孔に差し込み、その先端にナットを螺合させて締め付けることで、円環部材を介して二部材が連結される。この技術は、円環部材の挿通孔の位置を調整することで、二部材を自在な角度で接合可能である。 Patent Document 1 discloses a wood joining structure that has a simple configuration and can reduce the construction cost. This joining structure uses a whole screw bolt embedded in wood and a ring member, and the ring member is literally cylindrical and is arranged at the boundary of two members, and the whole screw bolt is connected individually. Embedded in the member, one end of which protrudes from the member. Then, all the screw bolts protruding from the member are inserted into the insertion hole of the annular member, and a nut is screwed to the tip of the annular bolt and tightened, thereby connecting the two members via the annular member. In this technique, the two members can be joined at an arbitrary angle by adjusting the position of the insertion hole of the annular member.

また特許文献２では、二部材を斜方向に接合するために用い、単純な構造で強度にも優れた建築用接合金具が開示されている。この接合金具は、母屋などの部材の端面に埋め込む連結棒と、二部材の間に配置する円筒形の受け金具で構成され、母屋の端面から突出させた連結棒を受け金具の係入溝に差し込み、さらに連結棒の先端にナットを螺合させて締め付ける。併せて、ボルトとナットを用い、受け金具を隅木などの部材に取り付ける。 Further, Patent Document 2 discloses a building joint for construction which is used for joining two members in an oblique direction and has a simple structure and excellent strength. This joining bracket is composed of a connecting rod embedded in the end face of a member such as a purlin and a cylindrical receiving bracket disposed between the two members, and the connecting rod projected from the end face of the purlin is inserted into the engaging groove of the receiving bracket. Insert and tighten the nut by screwing it onto the tip of the connecting rod. At the same time, using a bolt and a nut, attach the bracket to a member such as a corner tree.

次に特許文献３では、木造住宅などで用いられる複数の部材の接合構造が開示されている。ここでは、二本以上の副部材を主部材に接合することを想定しており、主部材と副部材は、連結部材を介して接合される。この連結部材は、アルミニウム合金などを素材としており、第一部材と第二部材で構成され、第一部材の側周面には、カギ型の嵌合孔を複数形成してあり、また第二部材の先端には、嵌合孔に嵌まり込む突起部を形成してある。そして主部材に第一部材を取り付け、副部材に第二部材を取り付け、第一部材と第二部材を嵌合することで、束と梁などの接合が実現する。 Next, Patent Document 3 discloses a joining structure of a plurality of members used in a wooden house or the like. Here, it is assumed that two or more sub members are joined to the main member, and the main member and the sub member are joined via the connecting member. This connecting member is made of an aluminum alloy or the like, and is composed of a first member and a second member. A plurality of key-shaped fitting holes are formed on the side peripheral surface of the first member. A protrusion that fits into the fitting hole is formed at the tip of the member. Then, the first member is attached to the main member, the second member is attached to the sub member, and the first member and the second member are fitted to each other, thereby joining the bundle and the beam.

前記のように、木造建築のデザインの多様化により、複数の部材を様々な交角で配置し、部材同士を斜方向に連結することも多い。このような場合において、様々な方向に伸びる部材を一括して一体化できるならば、現地での作業時間の短縮が期待できるほか、施工不良による強度の低下を招くこともない。なお特許文献２の建築用接合金具は、円筒形の受け金具を用いることで、角度に対する制約は大きく改善されるが、受け金具の軸線方向に部材を接合することを想定したものではない。 As described above, due to diversification of the design of wooden buildings, a plurality of members are often arranged at various intersection angles and the members are often connected in an oblique direction. In such a case, if the members extending in various directions can be integrated together, the work time at the site can be shortened, and the strength is not reduced due to poor construction. In addition, although the restriction | limiting with respect to an angle is greatly improved by using the cylindrical receiving metal fitting for the construction joining metal fitting of patent document 2, it does not assume joining a member in the axial direction of a receiving metal fitting.

近年は、森林資源の有効活用などの観点から、木造建築の大型化が進められており、その具体例として、大断面の登り梁を合掌形状に配置する構造が挙げられる。この登り梁には、常時下向きの大荷重が作用するため、その下端部同士を引き寄せ、倒伏を防ぐことが多い。この「下端部同士の引き寄せ」には、木材やテンションロッドなどを用いるが、単に対向する登り梁を引き寄せるのではなく、複数組の登り梁を接続することで、建築物の強度を一段と向上することができる。 In recent years, from the viewpoint of effective utilization of forest resources, the size of wooden buildings has been increased, and a specific example thereof is a structure in which climbing beams having a large cross section are arranged in a palm shape. Since a large downward load is always applied to the climbing beam, the lower ends of the climbing beam are often pulled together to prevent lodging. Wood and tension rods are used for this "drawing of the lower ends", but the strength of the building is further improved by connecting multiple pairs of climbing beams rather than simply pulling up the opposing climbing beams. be able to.

本発明はこうした実情を基に開発されたもので、様々な方向に伸びる複数の部材を一括して一体化できる連結具と、この連結具を用いた屋根構造の提供を目的としている。 The present invention has been developed based on such a situation, and an object of the present invention is to provide a connecting tool capable of integrating a plurality of members extending in various directions at once and a roof structure using the connecting tool.

前記の課題を解決するための請求項１記載の発明は、周接材と端接材を一体化する連結具であって、円筒状の本体と、該本体の端面を塞ぐ一対の閉止板と、該閉止板の表面から突出する接合手段と、前記本体の内部から差し込む固定ボルトと、一対の前記閉止板を引き寄せる寄せボルトと、からなり、前記周接材は、前記本体の半径方向に配置して、前記端接材は、前記本体の軸線方向に配置して、前記本体の側周面には、前記固定ボルトの軸部を差し込むため、内外を貫く貫通孔を設け、一対の前記閉止板は、前記本体の内部を貫通する前記寄せボルトで該本体と一体化して、前記固定ボルトにより、前記周接材を前記本体の外周面に引き寄せると共に、前記接合手段により、該本体の両端面に前記端接材を取り付け可能であることを特徴とする連結具である。 The invention according to claim 1 for solving the above-mentioned problem is a coupling tool for integrating the peripheral contact material and the end contact material, and includes a cylindrical main body and a pair of closing plates for closing the end face of the main body. A joining means projecting from the surface of the closing plate, a fixing bolt inserted from the inside of the main body, and a pair of bolts pulling the pair of the closing plates, and the circumferential contact member is disposed in the radial direction of the main body. The end connecting material is arranged in the axial direction of the main body, and a through hole is formed on the side peripheral surface of the main body so as to insert the shaft portion of the fixing bolt. The plate is integrated with the main body by the advancing bolts penetrating the inside of the main body, and the peripheral contact material is drawn to the outer peripheral surface of the main body by the fixing bolt, and both end surfaces of the main body by the joining means. The end connecting material can be attached to A consolidated tool for.

本発明による連結具は、木造建築の骨格など、各種木構造で用いるが、あらゆる状況で使用可能で、便宜上、連結される部材を周接材および端接材と称するものとする。周接材および端接材は、原則として木材（各種集成材を含む）であるが、圧縮荷重が作用することなく、安全性にも問題がないならば、一部をテンションロッドやワイヤーロープなど、金属製の部品に置き換えることもできる。 The connection tool according to the present invention is used in various wooden structures such as a skeleton of a wooden building, but can be used in any situation. For convenience, the members to be connected shall be referred to as a peripheral material and an end material. As a general rule, the surrounding material and the end material are wood (including various laminated materials), but if there is no problem with safety without any compressive load acting, part of it is tension rod, wire rope, etc. It can also be replaced with metal parts.

連結具は、本体と閉止板と接合手段と固定ボルトと寄せボルトを中心に構成され、他に付属品として、ナットやワッシャなどを用いることもある。そして本体は、円筒状の金属管で、その外周面は周接材の端面と向かい合い、何らかの手段で周接材の端面を本体に引き寄せる。なお一個の本体に対し、複数本の周接材を引き寄せることを想定している。さらに、この引き寄せを実現するため、周接材の端面には、ラグスクリューや異形棒鋼などの金属部品を埋め込み、本体の内部からこれらに向けて固定ボルトを差し込む。 The coupling tool is mainly composed of a main body, a closing plate, a joining means, a fixing bolt, and a gathering bolt, and a nut or a washer may be used as an accessory. The main body is a cylindrical metal tube, and the outer peripheral surface thereof faces the end surface of the surrounding material, and the end surface of the surrounding material is drawn to the main body by some means. It is assumed that a plurality of peripheral members are drawn to one main body. Furthermore, in order to realize this drawing, metal parts such as a lag screw and a deformed steel bar are embedded in the end face of the surrounding material, and a fixing bolt is inserted from the inside of the main body toward them.

閉止板は、本体の端面を塞ぐ円盤状のフタであり、両端面を塞ぐため、一個の本体に対して二枚用いる。したがって閉止板の直径は、本体の直径とほぼ等しくなる。また閉止板は、本体と一体化させる必要があり、対向する二枚の閉止板を寄せボルトで引き寄せ、閉止板を本体の端面に密着させる。なお寄せボルトの配置や使用数は自在で、寄せボルトと螺合するナットやメネジの配置も自在である。 The closing plate is a disc-shaped lid that closes the end face of the main body, and two pieces are used for one main body in order to close both end faces. Therefore, the diameter of the closing plate is approximately equal to the diameter of the main body. Further, the closing plate needs to be integrated with the main body, and the two closing plates facing each other are drawn together with a bolt so that the closing plate is brought into close contact with the end surface of the main body. The arrangement and number of use of the gathering bolts are arbitrary, and the arrangement of nuts and female screws that are screwed to the gathering bolts is also possible.

接合手段は、端接材を閉止板に取り付ける役割を担う。端接材は、本体の軸線方向に伸びる部材で、その端面は閉止板と向かい合い、閉止板と端接材との間に接合手段を介在させ、双方を一体化する。したがって、接合手段の具体的な構成は、端接材の種類に応じて都度異なる。なお接合手段は、溶接などで閉止板と一体化させる場合もあれば、閉止板の表面に載せる場合もある。接合手段を閉止板の表面に載せる場合、対向する接合手段を寄せボルトで引き寄せ、その内側で閉止板を挟み込む。 The joining means plays a role of attaching the end connecting material to the closing plate. The end contact material is a member extending in the axial direction of the main body, and its end face faces the closing plate, and a joining means is interposed between the closing plate and the end contact material to integrate both. Therefore, the specific configuration of the joining means varies depending on the type of end connecting material. The joining means may be integrated with the closing plate by welding or the like, or may be placed on the surface of the closing plate. When the joining means is placed on the surface of the closing plate, the opposing joining means are drawn together with a draw bolt, and the closing plate is sandwiched between them.

貫通孔は、前記の固定ボルトの軸部を差し込むため、本体の側周面に設ける孔で、想定される周接材の配置に基づき、その個数や位置を決める。なお貫通孔は、単純な丸孔ではなく、長孔とすることで、周接材の取り付け角度を調整できるようになる。そのほか本体の内周面は曲面で、そのままでは固定ボルトの頭部を安定して据え置くことができない。そこで半月状のワッシャを用いることが多い。 The through holes are holes provided on the side peripheral surface of the main body in order to insert the shaft portion of the fixing bolt, and the number and position thereof are determined based on the assumed arrangement of the surrounding material. The through hole is not a simple round hole but a long hole, so that the attachment angle of the circumferential contact material can be adjusted. In addition, the inner peripheral surface of the main body is a curved surface, and the head of the fixing bolt cannot be stably placed as it is. Therefore, a half-moon washer is often used.

このように、本体と閉止板と接合手段などからなる連結具を用いることで、本体の半径方向に伸びる複数の周接材と、本体の軸線方向に伸びる端接材と、を一個の連結具を用い、一括して一体化することができる。しかも周接材の取り付けは、本体の内部から固定ボルトを差し込み、これを締め付けるだけで完了し、現地での作業を簡単に終えることができる。また端接材の取り付けについても、接合手段により、作業性は良好である。 In this way, by using a connector composed of a main body, a closing plate, and a joining means, a plurality of peripheral contact materials extending in the radial direction of the main body and an end contact material extending in the axial direction of the main body are provided as one connector. Can be integrated together. Moreover, the attachment of the surrounding material can be completed simply by inserting a fixing bolt from the inside of the main body and tightening it, and the work at the site can be easily completed. In addition, the workability of the end attachment material is good due to the joining means.

請求項２記載の発明は、本体を一部改良したもので、本体の外周面には、一本の周接材の端面を載せるため、板状の台座を設けてあり、該台座から該周接材に向けてネジ釘等を差し込み、双方を一体化することを特徴としている。台座は金属製の板で、周接材の端面と接触し、台座から周接材に向けてネジ釘などを差し込むことで、周接材を台座に引き寄せる。また台座は、溶接などで本体の外周面と一体化させる。 The invention according to claim 2 is a partial improvement of the main body, and a plate-like pedestal is provided on the outer peripheral surface of the main body so as to place an end face of a single circumscribing material. It is characterized by inserting screw nails or the like toward the contact material and integrating both. The pedestal is a metal plate that comes into contact with the end face of the surrounding material and inserts a screw nail or the like from the pedestal toward the surrounding material to draw the surrounding material to the pedestal. The pedestal is integrated with the outer peripheral surface of the main body by welding or the like.

台座は、一個の本体に対して一枚だけで、台座に載ることのない他の周接材については、貫通孔に差し込む固定ボルトで本体に引き寄せる。また、台座から周接材に向けてネジ釘を差し込めるよう、台座の外縁付近は、本体から突出させることが望ましい。このように台座を設けることで、台座に据え付ける周接材については、ラグスクリューや異形棒鋼などの金属部品の埋め込みを省略することもできる。 Only one pedestal is provided for one main body, and other peripheral members that do not rest on the pedestal are drawn to the main body with fixing bolts inserted into the through holes. Moreover, it is desirable to project the vicinity of the outer edge of the base from the main body so that the screw nails can be inserted from the base toward the surrounding material. By providing the pedestal in this way, embedding of metal parts such as a lag screw and a deformed steel bar can be omitted with respect to the surrounding material to be installed on the pedestal.

請求項３記載の発明は、接合手段を特定するもので、接合手段は、閉止板と密着する前板と、該前板から直角に突出し且つ端接材に設けたスリットに差し込む側板と、からなる金具であり、側板をスリットに差し込み、該側板と端接材をドリフトピンなどの棒材で一体化することを特徴とする。端接材を取り付ける接合手段については、様々なものを選択可能だが、この発明では、広く普及しているコの字形または丁字形の金具としている。 The invention according to claim 3 specifies the joining means, and the joining means includes: a front plate that is in close contact with the closing plate; and a side plate that projects from the front plate at a right angle and is inserted into a slit provided in the end contact material. The side plate is inserted into the slit, and the side plate and the end contact material are integrated with a rod material such as a drift pin. Various joining means for attaching the end joining material can be selected. However, in the present invention, a U-shaped or C-shaped metal fitting is widely used.

この金具は、中央に位置する前板と、この前板から直角方向に突出する側板で構成され、前板は、閉止板の表面に接触させ、さらに寄せボルトで閉止板と一体化させる。また側板は、端接材の端部に差し込む。なお側板を差し込むため、端接材には、あらかじめスリットを加工しておく。そしてスリットに側板を差し込み、側板と端接材を貫くように各種棒材を差し込むと、双方が一体化される。棒材については、ドリフトピンやボルトなどを用いる。この発明で用いる金具は、広く普及している既存品で、入手や取り扱いが容易である。 This metal fitting is composed of a front plate located at the center and a side plate protruding in a direction perpendicular to the front plate. The front plate is brought into contact with the surface of the closing plate, and is further integrated with the closing plate by a closing bolt. The side plate is inserted into the end portion of the end connecting material. In addition, in order to insert a side plate, a slit is processed in the end contact material beforehand. Then, when the side plate is inserted into the slit and various bar members are inserted so as to penetrate the side plate and the end contact material, both are integrated. For rods, drift pins or bolts are used. The metal fittings used in the present invention are existing products that are widely used, and are easy to obtain and handle.

請求項４記載の発明は、これまでに開示した連結具の使用例を示すもので、合掌形状に配置される一対の登り梁が所定の間隔で並ぶ屋根構造であって、前記周接材に相当する束材および水平材と、前記端接材に相当する縦列材と、を用い、前記連結具は、一対の前記登り梁の頂部直下に配置し、一対の該登り梁の頂部と該連結具を前記束材で結び、また前記登り梁の下端部と該連結具を前記水平材で結び、さらに該連結具は、一対の登り梁毎に配置し、隣接する該連結管同士は、前記縦列材で接続してあることを特徴とする屋根構造である。 Invention of Claim 4 shows the usage example of the coupling tool disclosed until now, Comprising: It is a roof structure where a pair of climbing beams arrange | positioned at a palm shape are located in a line at predetermined intervals, Comprising: A corresponding bundle member and a horizontal member, and a column member corresponding to the end connecting member, and the connector is disposed immediately below the tops of the pair of climbing beams, and the tops of the pair of climbing beams The tool is tied with the bundle material, the lower end of the climbing beam and the connector are tied with the horizontal member, and the connector is arranged for each pair of climbing beams, and the adjacent connecting pipes are It is a roof structure characterized by being connected by tandem members.

この屋根構造において、連結具は、合掌形状に並ぶ一対の登り梁の頂部直下に配置する。そして、登り梁の頂部から連結具に向け、垂直に伸びる束材を配置するほか、個々の登り梁の下端部からは、連結具に向け、水平に伸びる水平材を配置する。さらに連結具の本体は、その外周面に束材や水平材が接触するように配置する。したがって束材や水平材は、周接材となる。なお登り梁は、建物の奥行方向に沿って複数対が並ぶことを前提としており、一対の登り梁に対し、一個の連結具を配置する。 In this roof structure, the connector is arranged directly below the tops of a pair of climbing beams arranged in a palm shape. In addition to arranging a vertically extending bundle from the top of the climbing beam toward the connector, a horizontal member extending horizontally from the lower end of each climbing beam is disposed toward the connector. Further, the main body of the connector is arranged so that the bundle material and the horizontal material are in contact with the outer peripheral surface thereof. Therefore, a bundle material and a horizontal material become a surrounding material. The climbing beams are premised on a plurality of pairs arranged in the depth direction of the building, and one connecting tool is arranged for the pair of climbing beams.

縦列材は、建物の奥行方向に伸びる部材で、隣接する連結具同士をつなぎ、複数対の登り梁を一体化し、建築物の強度を高める役割を担う。この縦列材は、必然的に連結具の閉止板と対向するため、端接材となる。このように複数対の登り梁が並ぶ屋根構造において、その頂部直下に連結管を配置することで、様々な方向から伸びる部材が一括して一体化され、登り梁の変形を拘束し、建築物の安全性を高めることができる。 The column member is a member extending in the depth direction of the building, and connects adjacent connectors, integrates a plurality of pairs of climbing beams, and plays a role of increasing the strength of the building. Since this column member inevitably faces the closing plate of the connector, it becomes an end contact member. In the roof structure in which multiple pairs of climbing beams are arranged in this way, by arranging the connecting pipe directly below the top, members extending from various directions are integrated together, restraining the deformation of the climbing beam, and building Can improve the safety.

請求項１記載の発明のように、連結具を本体と閉止板と接合手段などで構成することで、本体の外周面には、固定ボルトを介して周接材を取り付け、さらに本体の端面には、接合手段を介して端接材を取り付けることができる。そのため一個の連結具だけを用い、複数本の周接材と端接材を一括して一体化でき、現地での施工作業の簡素化や、占有空間の削減などが実現する。しかも周接材の取り付け作業は、本体の内部から固定ボルトを差し込み、これを締め付けるだけであり、施工不良による強度の低下を招きにくい。また端接材の取り付けについても、接合手段を用いるため、その作業は容易である。 As in the first aspect of the invention, the connecting tool is constituted by the main body, the closing plate, the joining means, and the like, so that a peripheral contact material is attached to the outer peripheral surface of the main body via a fixing bolt, and further to the end surface of the main body. Can attach the end fitting through the joining means. For this reason, only one connecting tool can be used, and a plurality of peripheral and end joints can be integrated together, simplifying construction work on site and reducing occupied space. In addition, the attaching work of the surrounding material only involves inserting a fixing bolt from the inside of the main body and tightening it, and it is difficult to cause a decrease in strength due to poor construction. In addition, since the joining means is used for attaching the end connecting material, the operation is easy.

請求項２記載の発明のように、本体の外周面に板状の台座を設け、一本の周接材の端面を台座に載せ、さらに台座から周接材に向けてネジ釘などを差し込むことで、周接材に対し、ラグスクリューや異形棒鋼などの金属部品の埋め込みを省略することもできる。そのため施工前の準備作業が簡素化する。なお、引張荷重に対する強度を向上させたい場合には、ラグスクリューなどとネジ釘との併用も可能である。 As in the invention described in claim 2, a plate-like pedestal is provided on the outer peripheral surface of the main body, the end surface of one peripheral member is placed on the pedestal, and screw nails are inserted from the pedestal toward the peripheral member. Thus, embedding of metal parts such as lag screw and deformed steel bar can be omitted with respect to the surrounding material. Therefore, the preparatory work before construction is simplified. In addition, when it is desired to improve the strength against a tensile load, a lag screw or the like and a screw nail can be used in combination.

請求項３記載の発明のように、接合手段として、前板と側板とからなるコの字形または丁字形の金具を用いることで、端接材の取り付け作業が一般的な形態となり、現地での利便性が向上する。しかも前板に寄せボルトを差し込むことで、金具を本体や閉止板と一体化することも容易である。そのほか金具は、広く普及している既存品を流用できるため、入手や取り扱いも容易である。 As in the invention described in claim 3, by using a U-shaped or C-shaped bracket made of a front plate and a side plate as a joining means, the attachment work of the end fitting becomes a general form, and on-site Convenience is improved. Moreover, it is easy to integrate the metal fitting with the main body and the closing plate by inserting the bolts into the front plate. In addition, the metal fittings are easy to obtain and handle because existing products that are widely spread can be used.

請求項４記載の発明のように、合掌形状に配置される一対の登り梁が所定の間隔で並ぶ屋根構造において、一対の登り梁の頂部直下に連結管を配置し、登り梁から伸びる束材や水平材を連結管で一括して一体化することで、少ない作業で登り梁の強度を高めることができる。しかも、隣接する連結管同士を縦列材で接続することで、複数対の登り梁が一体化され、建築物の強度が一段と向上する。 In a roof structure in which a pair of climbing beams arranged in a palm shape are arranged at a predetermined interval as in the invention described in claim 4, a connecting pipe is disposed immediately below the top of the pair of climbing beams, and the bundle extends from the climbing beam The strength of the climbing beam can be increased with a small amount of work by integrating the horizontal members and the horizontal members together with the connecting pipe. Moreover, by connecting adjacent connecting pipes with a column material, a plurality of pairs of climbing beams are integrated, and the strength of the building is further improved.

図１は、本発明による連結具の構成例を示しており、一個の連結具を用い、三本の周接材５１、５２と二本の端接材６１を一括して一体化することを想定している。この連結具は、本体１１と閉止板２１と金具３１を中心に構成され、本体１１の端面を閉止板２１と金具３１で挟み込む。また周接材５１、５２と端接材６１のいずれも、棒状の木材（各種集成材を含む）で、周接材５１、５２は、その一端面が本体１１の外周面と対向し、一本の周接材５１は垂直に伸びるが、残る二本の周接材５２は水平に伸びる。対して端接材６１は、本体１１の軸線方向に伸び、その一端が金具３１で保持される。なお図１では、余白の都合で端接材６１を一本だけ描いているが、実際には本体１１を挟み、二本を対向するように配置する。 FIG. 1 shows an example of the structure of a connector according to the present invention, wherein a single connector is used to integrate three peripheral members 51 and 52 and two end members 61 together. Assumed. This connector is configured around the main body 11, the closing plate 21 and the metal fitting 31, and the end surface of the main body 11 is sandwiched between the closing plate 21 and the metal fitting 31. Each of the surrounding members 51 and 52 and the end member 61 is a rod-like wood (including various laminated materials), and one end surface of each of the surrounding members 51 and 52 is opposed to the outer peripheral surface of the main body 11. The two circumferential members 51 extend vertically, while the remaining two circumferential members 52 extend horizontally. On the other hand, the end contact member 61 extends in the axial direction of the main body 11, and one end thereof is held by the metal fitting 31. In FIG. 1, only one end contact member 61 is drawn for the sake of margin, but actually, the main body 11 is sandwiched and the two are arranged to face each other.

連結具は、前記のように本体１１と閉止板２１と金具３１を中心に構成されるが、そのうち本体１１は金属製の円筒形で、その外周面に周接材５１、５２を引き寄せる。そのため本体１１の側周面には、複数の貫通孔１４を設けてある。貫通孔１４は、周接材５１、５２を引き寄せる固定ボルト１８の軸部を差し込むためのもので、本体１１の内外周面を貫き、周接材５１、５２の配置に応じて複数個所に設けてあり、位置調整ができるよう、いずれも周方向に伸びる長孔としてある。 As described above, the connector is mainly composed of the main body 11, the closing plate 21, and the metal fitting 31, and the main body 11 is made of a metal cylinder and draws the surrounding members 51 and 52 to the outer peripheral surface thereof. Therefore, a plurality of through holes 14 are provided on the side peripheral surface of the main body 11. The through-hole 14 is for inserting the shaft portion of the fixing bolt 18 that draws the peripheral contact materials 51 and 52, penetrates the inner and outer peripheral surfaces of the main body 11, and is provided at a plurality of locations according to the arrangement of the peripheral contact materials 51 and 52. Each of them is a long hole extending in the circumferential direction so that the position can be adjusted.

閉止板２１は、本体１１の両端面を塞ぐ担う円盤状の金属板で、必然的に本体１１を挟んで二枚用いる。閉止板２１と本体１１の直径（外径）は等しく、また閉止板２１と本体１１が同心に揃うよう、個々の閉止板２１の片面には、二箇所に突起２５を設けてある。突起２５は、本体１１の内周面に接触するように配置してあり、閉止板２１と本体１１との変位を規制する。そして二枚の閉止板２１は、寄せボルト３９で引き寄せ、本体１１を挟み込む。そのため閉止板２１は、本体１１と一体化する。 The closing plate 21 is a disk-shaped metal plate that closes both end surfaces of the main body 11, and necessarily uses two sheets sandwiching the main body 11. The diameters (outer diameters) of the closing plate 21 and the main body 11 are equal, and protrusions 25 are provided at two locations on one side of each closing plate 21 so that the closing plate 21 and the main body 11 are concentrically aligned. The protrusion 25 is disposed so as to come into contact with the inner peripheral surface of the main body 11 and restricts displacement between the closing plate 21 and the main body 11. Then, the two closing plates 21 are attracted by the abutting bolt 39 to sandwich the main body 11. Therefore, the closing plate 21 is integrated with the main body 11.

金具３１は、端接材６１を連結具に取り付ける役割を担う接合手段で、図１では既存品をそのまま流用している。この金具３１は、図１の右上に示すように、鋼鈑を二箇所で折り曲げ、コの字形にしたもので、中央に位置する前板３３の左右両端から側板３５が突出している。そして前板３３には、円柱状に突出するホゾ３４を上下二箇所に設けてあり、また側板３５には、ピン溝３７とピン孔３８を設けてある。ピン溝３７とピン孔３８は、金具３１と端接材６１を一体化するドリフトピン６８を差し込むためのもので、二枚の側板３５とも同形で配置してある。 The metal fitting 31 is a joining means that plays a role of attaching the end connecting member 61 to the coupling tool, and the existing product is used as it is in FIG. As shown in the upper right of FIG. 1, the metal fitting 31 is formed by bending a steel plate in two places into a U shape, and side plates 35 protrude from left and right ends of a front plate 33 located at the center. The front plate 33 is provided with columnar protrusions 34 that protrude in a columnar shape, and the side plate 35 is provided with pin grooves 37 and pin holes 38. The pin groove 37 and the pin hole 38 are for inserting a drift pin 68 that integrates the metal fitting 31 and the end contact material 61, and are arranged in the same shape on the two side plates 35.

金具３１の前板３３は、閉止板２１の表面に密着させるが、双方の変位を規制するため、閉止板２１にはホゾ穴２４を設けてあり、そこに金具３１のホゾ３４を嵌め込む。したがってホゾ３４とホゾ穴２４は、緩みなく嵌まり込むよう、直径を調整してある。また金具３１は、閉止板２１と同様、二個を対向するように配置し、これらを寄せボルト３９で引き寄せる。 The front plate 33 of the metal fitting 31 is brought into close contact with the surface of the closing plate 21, but in order to restrict the displacement of both, the closing plate 21 is provided with a relief hole 24 into which the relief 34 of the metal fitting 31 is fitted. Accordingly, the diameters of the side holes 34 and the side holes 24 are adjusted so that they fit into each other without looseness. Further, like the closing plate 21, the metal fittings 31 are arranged so as to face each other, and these are pulled together by a closing bolt 39.

寄せボルト３９は、一方の金具３１の側板３５の間から差し込み、ホゾ３４を経て対向する金具３１に到達させ、その先端に寄せナット４９を螺合させる。そして、寄せボルト３９と寄せナット４９を締め付けると、対向する金具３１が閉止板２１を挟み込み、本体１１と一体化される。なお寄せボルト３９の頭部や、寄せナット４９は、ホゾ３４の内部に収容され、前板３３の裏面から突出することはない。そのほかホゾ３４の中央には、寄せボルト３９の軸部を通すため、丸孔３６を設けてある。 The shift bolt 39 is inserted from between the side plates 35 of one metal fitting 31, reaches the metal fitting 31 that is opposed to the metal fitting 31 via the horn 34, and a movement nut 49 is screwed to the tip thereof. When the clamping bolt 39 and the clamping nut 49 are tightened, the opposing metal fitting 31 sandwiches the closing plate 21 and is integrated with the main body 11. It should be noted that the head of the gathering bolt 39 and the gathering nut 49 are accommodated inside the horn 34 and do not protrude from the back surface of the front plate 33. In addition, a round hole 36 is provided in the center of the horn 34 so as to pass the shaft portion of the closing bolt 39.

端接材６１は、金具３１を介して連結具と一体化する。そのため端接材６１の端部には、金具３１の側板３５を差し込むため、二列のスリット６５を加工してある。また端接材６１の端面において、二列のスリット６５の間には、前板３３を収容する段差８８を加工してある。さらに端接材６１の側面には、ドリフトピン６８を差し込むため、上下三列の側孔６４を加工してある。側孔６４は、ピン溝３７やピン孔３８と対応しており、ドリフトピン６８を介して端接材６１が金具３１と一体化する。なお施工時を考慮し、一番上の側孔６４には、あらかじめドリフトピン６８を打ち込んでおく。このドリフトピン６８は、スリット６５に側板３５を差し込んだ際、ピン溝３７で受け止められ、端接材６１の落下を防ぐ。 The end contact material 61 is integrated with the connector via the metal fitting 31. Therefore, in order to insert the side plate 35 of the metal fitting 31 into the end portion of the end contact member 61, two rows of slits 65 are processed. On the end face of the end contact member 61, a step 88 for accommodating the front plate 33 is processed between the two rows of slits 65. Further, side holes 64 in three upper and lower rows are processed on the side surface of the end contact member 61 in order to insert the drift pins 68. The side hole 64 corresponds to the pin groove 37 and the pin hole 38, and the end contact member 61 is integrated with the metal fitting 31 through the drift pin 68. In consideration of the construction, a drift pin 68 is driven in advance in the upper side hole 64. The drift pin 68 is received by the pin groove 37 when the side plate 35 is inserted into the slit 65, thereby preventing the end contact member 61 from falling.

周接材５１、５２を本体１１に引き寄せるため、図１では、周接材５１、５２の端面中央にラグスクリュー４１を埋め込んでいる。ラグスクリュー４１は円柱状の金属棒で、その側周面には螺旋状に伸びる凸条４４を設けてあるほか、一端面には六角形の頭部４３を設けてあり、その中心には、軸線方向に伸びるメネジ４５を設けてある。凸条４４は、周接材５１、５２の内部に食い込み、ラグスクリュー４１を不動状態にする。またラグスクリュー４１を埋め込む際は、頭部４３に工具を掛ける。 In order to draw the surrounding members 51 and 52 toward the main body 11, the lag screw 41 is embedded in the center of the end surfaces of the surrounding members 51 and 52 in FIG. 1. The lag screw 41 is a cylindrical metal rod, and has a spirally extending ridge 44 on its side circumferential surface, and a hexagonal head 43 on one end surface, A female screw 45 extending in the axial direction is provided. The ridges 44 bite into the surrounding members 51 and 52 to make the lag screw 41 immobile. When embedding the lag screw 41, a tool is hung on the head 43.

図１では、三本の周接材５１、５２のいずれとも、その端面中央に下穴５４を加工し、そこにラグスクリュー４１を埋め込んでいる。凸条４４は下穴５４の内周面に食い込み、大きな摩擦が生じるため、ラグスクリュー４１は周接材５１、５２と強固に一体化する。そして本体１１の内部に固定ボルト１８を差し込み、その軸部を貫通孔１４から突出させ、そこにラグスクリュー４１のメネジ４５を螺合させると、周接材５１、５２が本体１１に引き寄せられる。なお固定ボルト１８の頭部を安定させるため、半月状の曲面ワッシャ１９を用いている。曲面ワッシャ１９は、本体１１の内周面と同じ曲面を有する。そのほか、固定ボルト１８が差し込まれる貫通孔１４は長孔で、周接材５１、５２の方向は、ある程度の範囲で調整可能である。 In FIG. 1, a pilot hole 54 is machined at the center of the end face of each of the three circumferential members 51 and 52, and a lag screw 41 is embedded therein. Since the ridge 44 bites into the inner peripheral surface of the pilot hole 54 and a large friction is generated, the lag screw 41 is firmly integrated with the peripheral members 51 and 52. Then, when the fixing bolt 18 is inserted into the inside of the main body 11, its shaft portion is protruded from the through hole 14, and the female screw 45 of the lag screw 41 is screwed there, the peripheral contact materials 51 and 52 are attracted to the main body 11. In order to stabilize the head of the fixing bolt 18, a half-moon shaped curved washer 19 is used. The curved washer 19 has the same curved surface as the inner peripheral surface of the main body 11. In addition, the through hole 14 into which the fixing bolt 18 is inserted is a long hole, and the direction of the peripheral contact members 51 and 52 can be adjusted within a certain range.

図２は、図１に描いた各要素を組み付けていく過程を示している。本体１１の内部から周接材５１、５２のラグスクリュー４１に向けて固定ボルト１８を差し込み、計三本の周接材５１、５２を本体１１に引き寄せている。なお固定ボルト１８の頭部は、曲面ワッシャ１９により、安定して据え置かれている。また固定ボルト１８を締め付けた後、閉止板２１のホゾ穴２４に金具３１のホゾ３４を嵌め込み、閉止板２１を本体１１の端面に接触させる。そして、本体１１を挟み込むように二枚の閉止板２１を配置した後、一方から寄せボルト３９を差し込み、その先端に寄せナット４９を螺合させると、対向する二個の金具３１が閉止板２１と本体１１を挟み込み、これらが一体化される。 FIG. 2 shows a process of assembling the elements drawn in FIG. The fixing bolt 18 is inserted from the inside of the main body 11 toward the lag screw 41 of the peripheral contact materials 51 and 52, and a total of three peripheral contact materials 51 and 52 are drawn toward the main body 11. The head of the fixing bolt 18 is stably placed by a curved washer 19. Further, after tightening the fixing bolt 18, the tenon 34 of the metal fitting 31 is fitted into the tenon hole 24 of the closing plate 21, and the closing plate 21 is brought into contact with the end surface of the main body 11. Then, after the two closing plates 21 are arranged so as to sandwich the main body 11, when a closing bolt 39 is inserted from one side and a closing nut 49 is screwed to the tip, the two opposing metal fittings 31 are connected to the closing plate 21. And the main body 11 are sandwiched, and these are integrated.

図３は、図１の最終形態を示し、連結具を中心として三本の周接材５１、５２と二本の端接材６１が一体化している。周接材５１、５２は、いずれもその一端側が本体１１の外周面に引き寄せられ、そのうち一本の周接材５１は、連結具から直立しており、残る二本の周接材５２は、対向するように水平に伸びている。また端接材６１は、金具３１を介して連結具に取り付けられ、本体１１の軸線方向に伸びている。したがって、この状態を真上から見下ろすと、二本の周接材５２と二本の端接材６１が十字状に並ぶ。このように、本発明による連結具は、様々な方向に伸びる複数の部材を一括して一体化することができる。 FIG. 3 shows the final form of FIG. 1, in which three peripheral contact members 51 and 52 and two end contact members 61 are integrated with a connector as a center. Each of the surrounding members 51 and 52 is drawn to the outer peripheral surface of the main body 11 at one end, and one of the surrounding members 51 stands upright from the coupling tool, and the remaining two surrounding members 52 are: It extends horizontally to face each other. The end contact member 61 is attached to the connector via the metal fitting 31 and extends in the axial direction of the main body 11. Therefore, when this state is looked down from directly above, the two surrounding contact members 52 and the two end contact members 61 are arranged in a cross shape. Thus, the connector according to the present invention can collectively integrate a plurality of members extending in various directions.

図１から図３では、周接材５１、５２を本体１１に引き寄せるため、周接材５１、５２の内部にラグスクリュー４１を埋め込んでいる。ただし本発明は、ラグスクリュー４１の使用を前提とする訳ではなく、様々な従来技術を用いることができ、他の例として、異形棒鋼が挙げられる。異形棒鋼は、接着剤で周接材５１、５２に固着させるが、固着後は、ラグスクリュー４１と同様の形態となる。他にも、周接材５１、５２の端面からシャフトを埋め込み、このシャフトを各種ピンで周接材５１、５２に固定した後、シャフトに設けたネジに向け、固定ボルト１８を差し込むこともできる。 In FIG. 1 to FIG. 3, the lag screw 41 is embedded in the peripheral contact members 51, 52 in order to draw the peripheral contact members 51, 52 to the main body 11. However, the present invention is not premised on the use of the lag screw 41, and various conventional techniques can be used. Another example is a deformed bar. The deformed steel bar is fixed to the circumferential contact materials 51 and 52 with an adhesive, but after fixing, the deformed steel bar has the same form as the lag screw 41. In addition, after the shaft is embedded from the end faces of the peripheral members 51 and 52 and the shaft is fixed to the peripheral members 51 and 52 with various pins, the fixing bolt 18 can be inserted toward the screw provided on the shaft. .

図４は、本発明による連結具と併用する係留具７１を示している。この係留具７１は、底板７２と筒体７４で構成され、一方材８１および他方材８２と称する二本の部材を一体化するために用い、一方材８１と他方材８２との交角を調整できることを特徴としている。係留具７１の底板７２は、一方材８１の表面に接触する金属板で、また筒体７４は底板７２の上面に載る。さらに底板７２と筒体７４は、溶接で強固に一体化してあり、双方の境界には、補強のためリブ７３を設けてある。 FIG. 4 shows a mooring tool 71 for use with a connector according to the invention. The mooring tool 71 is composed of a bottom plate 72 and a cylindrical body 74, and is used to integrate two members called one member 81 and the other member 82, and the crossing angle between the one member 81 and the other member 82 can be adjusted. It is characterized by. The bottom plate 72 of the mooring tool 71 is a metal plate that contacts the surface of the one material 81, and the cylindrical body 74 is placed on the upper surface of the bottom plate 72. Further, the bottom plate 72 and the cylindrical body 74 are firmly integrated by welding, and ribs 73 are provided at the boundary between them for reinforcement.

一方材８１の上面には、下穴８３を加工してあり、そこにラグスクリュー４１を埋め込む。その後、係留具７１の底板７２からラグスクリュー４１に向けて圧着ボルト７８を差し込むと、係留具７１が一方材８１に固定される。また他方材８２の下端面中央には、下穴８３を加工してあり、そこにもラグスクリュー４１を埋め込んである。そして筒体７４の側周面には、長孔状の調整孔７５を設けてあり、筒体７４の内部に固定ボルト７７を差し込み、その軸部を調整孔７５から突出させ、そこに他方材８２のラグスクリュー４１を螺合させ、他方材８２を筒体７４に引き寄せる。 On the other hand, a pilot hole 83 is processed on the upper surface of the material 81, and the lag screw 41 is embedded therein. Thereafter, when the crimping bolt 78 is inserted from the bottom plate 72 of the anchoring tool 71 toward the lag screw 41, the anchoring tool 71 is fixed to the one member 81. A pilot hole 83 is machined in the center of the lower end surface of the other material 82, and the lag screw 41 is embedded therein. An adjustment hole 75 having a long hole shape is provided on the side peripheral surface of the cylinder 74, and a fixing bolt 77 is inserted into the cylinder 74 so that the shaft portion protrudes from the adjustment hole 75, and the other material is provided there. The lag screw 41 of 82 is screwed together, and the other material 82 is drawn to the cylinder 74.

係留具７１と一方材８１は、変位不能に一体化されるが、他方材８２については、調整孔７５により、ある程度の範囲で揺動することができ、一方材８１と他方材８２との交角も調整可能である。ただし固定ボルト７７を強固に締め付けると、摩擦により変位不能となり、一方材８１と他方材８２が特定の交角で連結される。なお固定ボルト７７の頭部を安定して据え置くため、ここでも曲面ワッシャ７９を用いている。 The mooring tool 71 and the one material 81 are integrated so that they cannot be displaced, but the other material 82 can be swung within a certain range by the adjustment hole 75, and the intersection angle between the one material 81 and the other material 82. Can also be adjusted. However, if the fixing bolt 77 is firmly tightened, it cannot be displaced due to friction, and the one member 81 and the other member 82 are connected at a specific crossing angle. Note that a curved washer 79 is also used here in order to stably place the head of the fixing bolt 77.

図５は、本発明による連結具を用いた屋根構造を示す。この図では、図１などに描いた連結具を用い、合掌形状に配置された登り梁８５の変形を防ぎ、屋根構造の剛性を高めている。登り梁８５は、屋根全体の荷重を受け止め、室内空間を確保する極めて重要な骨格材で、屋根の傾斜に沿って伸びているが、本発明では、二本の登り梁８５を合掌形状に配置することを前提としており、対向する二本の登り梁８５の境界が頂部になる。そして連結具は、この頂部の直下に配置する。 FIG. 5 shows a roof structure using a connector according to the invention. In this figure, the connecting tool depicted in FIG. 1 or the like is used to prevent the climbing beam 85 arranged in a palm shape from being deformed and to increase the rigidity of the roof structure. The climbing beam 85 is an extremely important skeleton material that receives the load of the entire roof and secures an indoor space. The climbing beam 85 extends along the slope of the roof. In the present invention, the two climbing beams 85 are arranged in a palm shape. The boundary between the two climbing beams 85 facing each other is the top. And a connector is arrange | positioned directly under this top part.

図５の上方には、一対の登り梁８５を一個の連結具で補強した状態を描いてあり、一対の登り梁８５の中央には、垂直に伸びる周接材５１を配置してある。この周接材５１は束材で、登り梁８５の頂部と連結具を結んでいる。また個々の登り梁８５の下部には、図４で開示した係留具７１を取り付けてある。なお図５では、登り梁８５の下斜面に係留具７１を取り付けてあり、図４とは上下が反転している。そして係留具７１と連結具は、周接材５２で結ばれている。この周接材５２は、水平方向に伸びるため、水平材を称するものとする。このように連結具には、計三本の周接材５１、５２が集積しており、いずれも本体１１の外周面に引き寄せられている。 In the upper part of FIG. 5, a pair of climbing beams 85 is depicted as being reinforced by a single connecting tool, and a circumferential contact member 51 extending vertically is disposed at the center of the pair of climbing beams 85. The surrounding material 51 is a bundle material, and connects the top portion of the climbing beam 85 to the connecting tool. The anchoring tool 71 disclosed in FIG. 4 is attached to the lower part of each climbing beam 85. In FIG. 5, a mooring tool 71 is attached to the lower slope of the climbing beam 85, and is upside down from FIG. 4. The mooring tool 71 and the connecting tool are connected by a circumferential contact material 52. Since the circumferential contact material 52 extends in the horizontal direction, it is referred to as a horizontal material. Thus, a total of three contact materials 51 and 52 are accumulated in the connector, and all of them are drawn to the outer peripheral surface of the main body 11.

このように、三本の周接材５１、５２を連結具で一括して一体化することで、一対の登り梁８５は変形を拘束され、剛性が向上する。そのため登り梁８５の延長を増大させ、より広大な室内空間を確保することもできる。なお係留具７１は、図４に示すように調整孔７５を設けてあり、あらゆる傾斜角度の登り梁８５に対応できる。また登り梁８５の下端部は、柱８６に載せられている。そのほか、登り梁８５の頂部における周接材５１（束材）の取り付けは、様々な従来技術を用いている。 In this way, by integrally integrating the three circumferential members 51 and 52 with the connecting tool, the pair of climbing beams 85 is restrained from being deformed and the rigidity is improved. Therefore, the extension of the climbing beam 85 can be increased, and a vast indoor space can be secured. The mooring tool 71 is provided with an adjustment hole 75 as shown in FIG. 4 and can correspond to climbing beams 85 of any inclination angle. Further, the lower end portion of the climbing beam 85 is placed on the pillar 86. In addition, various conventional techniques are used for attaching the circumferential contact member 51 (bundle member) at the top of the climbing beam 85.

本発明による連結具は、周接材５１、５２のほか、端接材６１も取り付けることができる。そのため図５の下方に描くように、一対の登り梁８５が建物の奥行方向に並ぶ場合、隣接する連結具同士を端接材６１で結ぶことができる。なお端接材６１は、隣接する連結具の間を結ぶことから、縦列材と称するものとする。このように連結具を用い、周接材５１、５２や端接材６１を配置することで、あらゆる方向で屋根構造の剛性を高めることができる。 In addition to the peripheral contact materials 51 and 52, the end connection material 61 can be attached to the connector according to the present invention. Therefore, as illustrated in the lower part of FIG. 5, when a pair of climbing beams 85 are arranged in the depth direction of the building, adjacent connecting members can be connected by the end contact material 61. Note that the end connecting member 61 is referred to as a column member because it connects between adjacent connecting members. Thus, the rigidity of a roof structure can be improved in all directions by arrange | positioning the surrounding materials 51 and 52 and the end-connecting material 61 using a coupling tool.

図６は、本体１２の形状例を示す。本体１１、１２は、図１などに描くような単純な円筒形に限定されるものではなく、この図の本体１２のように、台座１５を設けることもできる。台座１５は、周接材５１の端面を載せる板で、溶接などで本体１２と一体化する。そして、実際に周接材５１を台座１５に載せた後、双方をネジ釘５６で一体化する。そのため台座１５には、ネジ釘５６の軸部を差し込む抜き孔１６と、その頭部を収容するザグリ１７を設けてある。なお抜き孔１６やザグリ１７は、ネジ釘５６が周接材５１の中心に向かうよう、台座１５の表面に対して傾きを有する。また本体１２は、ネジ釘５６の差し込みに支障がないよう、その延長を抑制してある。 FIG. 6 shows an example of the shape of the main body 12. The main bodies 11 and 12 are not limited to a simple cylindrical shape as depicted in FIG. 1 and the like, and a pedestal 15 can be provided as in the main body 12 in this figure. The pedestal 15 is a plate on which the end face of the circumferential contact material 51 is placed, and is integrated with the main body 12 by welding or the like. Then, after the circumferential contact member 51 is actually placed on the pedestal 15, both are integrated by the screw nails 56. Therefore, the pedestal 15 is provided with a punch hole 16 into which the shaft portion of the screw nail 56 is inserted and a counterbore 17 that accommodates the head portion. The punch hole 16 and the counterbore 17 are inclined with respect to the surface of the base 15 so that the screw nails 56 are directed toward the center of the circumferential contact member 51. Further, the main body 12 is restrained from being extended so that the insertion of the screw nails 56 is not hindered.

周接材５１、５２を柔軟に配置できるよう、一個の本体１２に対し、台座１５は一個に留めることが望ましい。したがって台座１５から離れた位置には、これまでと同様に貫通孔１４を設ける。台座１５を設けることで、周接材５１にはラグスクリュー４１などを埋め込む必要がなく、部品点数の削減を期待できる。またネジ釘５６は、複数本差し込むことから、連結具と周接材５１にねじれが生じることもない。なお、周接材５１に過大な引張荷重が作用する場合、その中心にラグスクリュー４１を埋め込み、ラグスクリュー４１とネジ釘５６の双方で荷重を受け止めることもできる。ただしこれを実現するには、台座１５や本体１２に孔などを設ける必要がある。 It is desirable that the pedestal 15 is fastened to a single body 12 so that the surrounding members 51 and 52 can be arranged flexibly. Therefore, the through hole 14 is provided at a position away from the base 15 as before. By providing the pedestal 15, it is not necessary to embed the lag screw 41 or the like in the circumferential contact material 51, and a reduction in the number of parts can be expected. Further, since a plurality of screw nails 56 are inserted, the connector and the peripheral contact member 51 are not twisted. When an excessive tensile load acts on the circumferential contact member 51, the lag screw 41 can be embedded in the center thereof and the load can be received by both the lag screw 41 and the screw nail 56. However, in order to realize this, it is necessary to provide holes or the like in the base 15 or the main body 12.

図７は、端接材６２としてテンションロッドを用いた場合を示す。本発明による周接材５１、５２や端接材６１、６２は、原則として木材であるが、圧縮荷重が作用することなく、安全性にも問題がないならば、一部をテンションロッドやワイヤーロープなど、金属製の部品に置き換えることも可能で、図７では、端接材６２としてテンションロッドを用いている。またこの端接材６２に対応し、接合手段としてクレビス２６を用いている。テンションロッドは、引張荷重を伝達する金属棒だが、他の部材との接続のため、その端部にはヘッド６６を結合してあり、ヘッド６６の側面にはピン孔６７を設けてある。 FIG. 7 shows a case where a tension rod is used as the end connecting material 62. The peripheral contact materials 51 and 52 and the end contact materials 61 and 62 according to the present invention are made of wood in principle. However, if there is no problem in terms of safety without the application of a compressive load, a part of them may be a tension rod or a wire. It can be replaced with a metal part such as a rope. In FIG. 7, a tension rod is used as the end contact member 62. Further, the clevis 26 is used as a joining means corresponding to the end connecting material 62. The tension rod is a metal rod that transmits a tensile load. For connection with other members, a head 66 is coupled to an end portion of the tension rod, and a pin hole 67 is provided on a side surface of the head 66.

クレビス２６は、二個が平行に並んでおり、その間にヘッド６６が入り込む。またクレビス２６の先端付近にもピン孔２７を設けてあり、クレビス２６とヘッド６６のピン孔２７、６７を同心に揃え、そこに支点ピン６９を差し込むと、端接材６２が連結具に取り付けられる。なおクレビス２６は、溶接で閉止板２２と一体化してある。さらに、図の右側の閉止板２２の中心には、寄せボルト３９の軸部を差し込む丸孔２８を設けてあり、図の左側の閉止板２２の中心には、寄せボルト３９と螺合するメネジ２９を設けてある。このように、閉止板２２や接合手段の構成を変えることで、あらゆる端接材６１、６２を取り付けることができる。そのほか実際には、支点ピン６９の抜け止め対策も必要である。 Two clevises 26 are arranged in parallel, and the head 66 enters between them. Also, a pin hole 27 is provided in the vicinity of the tip of the clevis 26. When the clevis 26 and the pin holes 27 and 67 of the head 66 are aligned concentrically, and the fulcrum pin 69 is inserted there, the end contact member 62 is attached to the coupling tool. It is done. The clevis 26 is integrated with the closing plate 22 by welding. Further, a round hole 28 into which the shaft portion of the contact bolt 39 is inserted is provided at the center of the right closing plate 22 in the figure, and a female screw that is screwed into the contact bolt 39 is provided at the center of the left closing plate 22 in the figure. 29 is provided. In this way, any end contact materials 61 and 62 can be attached by changing the configuration of the closing plate 22 and the joining means. In addition, actually, it is necessary to take measures to prevent the fulcrum pin 69 from coming off.

図８は、図１の形態を一部変更した構成を示し、接合手段として丁字形の金具３２を用いている。この金具３２は、前板３３の中央から側板３５が突出しており、前板３３には寄せボルト３９を差し込むため、丸孔３６を設けてあり、側板３５にはドリフトピン６８を通すため、ピン溝３７とピン孔３８を設けてある。また閉止板２３には、寄せボルト３９を差し込むため、四箇所に丸孔２８を設けてある。そして、対向する金具３２を寄せボルト３９と寄せナット４９で引き寄せると、その間に閉止板２３が挟み込まれ、本体１１と閉止板２３と金具３２が一体化する。 FIG. 8 shows a configuration in which the form of FIG. 1 is partly changed, and a letter-shaped fitting 32 is used as a joining means. The metal plate 32 has a side plate 35 projecting from the center of the front plate 33, a round hole 36 is provided in the front plate 33 for inserting the approach bolt 39, and a drift pin 68 is passed through the side plate 35. A groove 37 and a pin hole 38 are provided. The closing plate 23 is provided with round holes 28 at four locations for inserting the bolts 39. Then, when the opposing metal fitting 32 is pulled by the adjusting bolt 39 and the adjusting nut 49, the closing plate 23 is sandwiched therebetween, and the main body 11, the closing plate 23, and the metal fitting 32 are integrated.

金具３２に対応し、端接材６１の中央には一列のスリット６５を加工してあり、そこに金具３２の側板３５を差し込み、双方を貫くようにドリフトピン６８を打ち込むと、端接材６１が連結具と一体化する。なお寄せボルト３９の頭部や、寄せナット４９を埋め込むため、端接材６１の端面には、何らかの空洞を設ける必要がある。 Corresponding to the metal fitting 32, a row of slits 65 is machined in the center of the end fitting 61, and when the side plate 35 of the metal fitting 32 is inserted therein and the drift pin 68 is driven so as to penetrate both, the end fitting 61 Is integrated with the connector. In addition, in order to embed the head of the gathering bolt 39 and the gathering nut 49, it is necessary to provide some cavity on the end surface of the end connecting material 61.
