Description

本発明は、座具、それを使用した木質部材の接合構造及び木質部材の接合方法に関するものである。詳しくは、木軸構造体を施工するに当たり、迅速な施工を可能にすると共に、施工後の構造体を下方から見たときに金属製の部品の露出が少なく、積極的に木質の構造体を見せる上で、意匠的に、より好ましい形態とすることができるものに関する。 The present invention relates to a sitting tool, a wood member joining structure using the sitting tool, and a wood member joining method. Specifically, when constructing a wooden shaft structure, it enables rapid construction, and when the structure after construction is viewed from below, there is less exposure of metal parts, and a wooden structure is actively It is related with what can be made into a more preferable form in terms of design.

近年、木質の橋や屋根等の各種構造物の骨組等、各種の木軸構造体が広く施工されている。木軸構造体は、構成部材である柱部材や梁部材等の木質部材を連結ボルトや連結金具等の連結具により接合して構築されている。木質部材を接合する構造としては、様々なものが採用されているが、例えば本願発明者が提案した特許文献１に記載された木質部材の接合構造がある。なお、特許文献１には、木質部材の接合構造に使用する座具が発明として開示されている。 In recent years, various wooden shaft structures such as a framework of various structures such as wooden bridges and roofs have been widely constructed. The wooden shaft structure is constructed by joining wooden members such as column members and beam members, which are constituent members, with a connecting tool such as a connecting bolt or a connecting bracket. Various structures are used for joining the wood members. For example, there is a wood member joining structure described in Patent Document 1 proposed by the present inventor. Patent Document 1 discloses a sitting tool used for a wood member joining structure as an invention.

特許文献１に記載された木質部材の接合構造は、接合する木質部材の接合部で連結ボルトを隣接交差させて通し孔に通し、各連結ボルトを座具とナットを介し固定して木質部材を連結するものである。また、各連結ボルトの両端部で使用される座具は、木繊維方向の面に対し作用する荷重による当該面の変形を抑えて、木軸構造体の施工後の緩みや変形を抑止できるというものである。 In the wood member joining structure described in Patent Document 1, the connection bolts are adjacently crossed at the joint portion of the wood members to be joined and passed through the through holes, and each connection bolt is fixed via a seat and a nut. To be connected. In addition, the sitting tool used at both ends of each connecting bolt can suppress the deformation and deformation after the construction of the wooden shaft structure by suppressing the deformation of the surface due to the load acting on the surface in the direction of the wood fiber. Is.

上記従来の木質部材の連結構造及び座具は、木軸構造体の施工後の緩みや変形を抑止することができる点においては、充分に有用である。しかしながら、当該接合構造の施工を実地に重ねて行くに伴い、更に改良の余地があることも分かってきた。 The connection structure and the sitting tool of the conventional wooden member are sufficiently useful in that the loosening and deformation after the construction of the wooden shaft structure can be suppressed. However, it has been found that there is room for further improvement as the construction of the joint structure is repeated on the ground.

すなわち、座具を収容する穴を木質部材にあらかじめ加工しておく必要があると共に、連結ボルト一本当たり、二個の座具及びナットが必要になる。このため、連結ボルトを接合部に固定する作業に相当な手間がかかるので、施工に長い時間を要するという課題を生じていた。 That is, it is necessary to process a hole for accommodating the sitting tool in advance in the wooden member, and two sitting tools and nuts are required for each connecting bolt. For this reason, since the work which fixes a connection bolt to a junction takes considerable time, the subject that construction requires a long time has arisen.

また、施工後、接合部を下方から見たとき、連結ボルト一本当たり、一箇所に座具とナットが露出しており、近年の傾向として、隠すよりむしろ積極的に構造物の細部を見せることも多い木軸構造では、木質部分に露出した金属製の部品が点在している形態は、意匠的に見てもあまり好ましいとはいえなかった。 In addition, when the joint is viewed from below after construction, the seating fixture and nut are exposed at one location for each connecting bolt, and as a recent trend, the details of the structure are actively shown rather than hidden. In many cases, in a wooden shaft structure, a form in which metal parts exposed on a wood portion are scattered is not so preferable from the viewpoint of design.

本発明は、以上の点を鑑みて創案されたものであり、木軸構造体を施工するに当たり、迅速な施工を可能にすると共に、施工後の構造体を下方から見たときに金属製の部品の露出が少なく、積極的に木質の構造体を見せる上で、意匠的に、より好ましい形態とすることができる座具、それを使用した木質部材の接合構造及び木質部材の接合方法を提供することを目的とするものである。 The present invention was devised in view of the above points. In constructing a wooden shaft structure, the present invention enables rapid construction, and is made of metal when the structure after construction is viewed from below. Providing a seating tool that can be made into a more preferable form in terms of design with less exposure of parts and positively showing a woody structure, a woody member joining structure using the same, and a woody member joining method It is intended to do.

（１）上記の目的を達成するため、本発明は、長方形で平板状の座具本体と、該座具本体の相対する位置にある一組の端縁部の接合面と反対の面に形成され、先端縁へ向け板厚が薄くなるよう所要角度で傾斜した平らな座面と、前記座具本体の前記端縁部に設けられ、前記座面から前記座面と直角方向に反対の面に貫通した、ラグスクリューを通すための所要数の通し孔とを備える木質部材の接合構造に使用する座具である。 (1) In order to achieve the above object, the present invention is formed on a surface opposite to a joint surface of a rectangular flat plate seat body and a pair of end edges located at opposite positions of the seat body. And a flat seat surface inclined at a required angle so that the plate thickness is reduced toward the tip edge, and a surface opposite to the seat surface from the seat surface in a direction perpendicular to the seat surface. It is a sitting tool used for the joining structure of the wooden member provided with the required number of through-holes for letting the lag screw pass through.

本発明に係る座具は、長方形で平板状の座具本体の相対する位置にある一組の端縁部の接合面と反対の面に、先端縁へ向け板厚が薄くなるよう所要角度で傾斜した平らな座面を有しているので、座面に設けられる通し孔の配列方向を、座具の両側の端縁部で平行にすることができる。これによれば、ラグスクリューの位置が揃うので、施工がしやすくなる。 The sitting tool according to the present invention is formed at a required angle so that the plate thickness decreases toward the tip edge on the surface opposite to the joint surface of the pair of end edges located at the opposite positions of the rectangular and flat seat body. Since it has the inclined flat seat surface, the arrangement direction of the through-hole provided in a seat surface can be made parallel in the edge part of the both sides of a sitting tool. According to this, since the positions of the lag screws are aligned, it becomes easy to perform the construction.

また、座面は、ラグスクリューを木質部材に斜めにねじ込んだ際に、ラグスクリューが有するヘッドが圧着する部分となる。更に、座面は、反対側の接合面に対して傾斜しており、このため接合面に密着する木質部材の接合面に対しても傾斜するので、ラグスクリューを木質部材に斜めにねじ込んだときにヘッドの圧着面と座面は隙間なく平行に密着し、これにより最大面積で均等な圧力を以て密着する。 Further, the seat surface becomes a portion to which the head of the lag screw is crimped when the lag screw is obliquely screwed into the wooden member. Furthermore, the seating surface is inclined with respect to the joint surface on the opposite side. Therefore, the seat surface is also inclined with respect to the joint surface of the wooden member that is in close contact with the joint surface, so that when the lag screw is screwed into the wooden member obliquely. In addition, the pressure-bonding surface and the seating surface of the head are in close contact with each other without any gaps, and thereby are in close contact with a uniform pressure with a maximum area.

更に、座具は、木質部材の接合構造に使用した際に、ラグスクリューを座具の通し孔に通し、木質部材に斜めにねじ込むことで、木質部材との接合が可能になるので、従来のように連結ボルト一本当たり、二個の座具とナットを使用して固定する構造と比較して、施工の手間が軽減され、木軸構造体を施工するに当たり、迅速な施工が可能になる。なお、本発明にいう「長方形」の用語は、いうまでもなく「正方形」を含む意味で使用している。 Furthermore, when the sitting tool is used for the joining structure of the wooden member, it is possible to join the wooden member by passing the lag screw through the through hole of the sitting tool and screwing it diagonally into the wooden member. Thus, compared to a structure that uses two seating fixtures and nuts to fix each connection bolt, the labor of construction is reduced and rapid construction is possible when constructing a wooden shaft structure. . It should be noted that the term “rectangle” in the present invention is used to mean “square”.

（２）本発明の座具は、長方形で平板状の座具本体と、該座具本体の相対する位置にある一組の端縁部の表裏両側の接合面に形成され、先端縁へ向け板厚が薄くなるよう所要角度で傾斜した平らな座面と、前記座具本体の前記端縁部に設けられ、表裏両側の前記座面のうち一方の座面と直角方向に反対の面に貫通した、ラグスクリューを通すための所要数の通し孔、及び他方の座面と直角方向に反対の面に貫通した、ラグスクリューを通すための所要数の通し孔とを備える。 (2) The sitting tool of the present invention is formed on a joint surface on both front and back sides of a pair of end edges located at opposite positions of the rectangular and flat sitting tool body and facing the leading edge. A flat seat surface inclined at a required angle so as to reduce the plate thickness, and provided on the edge portion of the seat body, on a surface opposite to one of the seat surfaces on both the front and back sides in a direction perpendicular to the seat surface. A required number of through-holes for passing the lag screw and a required number of through-holes for passing the lag screw penetrated in a surface perpendicular to the other seating surface.

本発明に係る座具は、長方形で平板状の座具本体の相対する位置にある一組の端縁部の表裏両側の接合面に、先端縁へ向け板厚が薄くなるよう所要角度で傾斜した平らな座面を有しているので、座面に設けられる通し孔の配列方向を、座具の両側の端縁部で平行にすることができる。これによれば、ラグスクリューの位置が揃うので、施工がしやすくなる。 The sitting tool according to the present invention is inclined at a required angle so that the plate thickness is reduced toward the tip edge on the joint surfaces on both the front and back sides of a pair of end edges located at opposite positions of the rectangular and flat seat body. Therefore, the arrangement direction of the through holes provided in the seating surface can be made parallel at the edge portions on both sides of the sitting tool. According to this, since the positions of the lag screws are aligned, it becomes easy to perform the construction.

また、座面は、ラグスクリューを木質部材に斜めにねじ込んだ際に、ラグスクリューが有するヘッドが圧着する部分となる。更に、座面は、各接合面に対して傾斜しており、このため接合面に密着する木質部材の接合面に対しても傾斜するので、ラグスクリューを通し孔に通して木質部材に斜めにねじ込んだときに、ヘッドの圧着面と座面は隙間なく平行に密着し、これにより最大面積で均等な圧力を以て密着する。 Further, the seat surface becomes a portion to which the head of the lag screw is crimped when the lag screw is obliquely screwed into the wooden member. Furthermore, the seating surface is inclined with respect to each joint surface, and therefore also with respect to the joint surface of the wooden member that is in close contact with the joint surface, so that the lug screw is passed through the through hole and obliquely on the wooden member. When screwed in, the pressure-bonding surface and the seating surface of the head are in close contact with each other without any gap, and thereby are in close contact with even pressure in the maximum area.

更に、座具は、木質部材の接合構造に使用した際に、表裏両側の座面のうち一方の座面と直角方向に反対の面に貫通した通し孔にラグスクリューを通し、他方の座面と直角方向に反対の面に貫通した通し孔にラグスクリューを通して、木質部材にねじ込まれる。すなわち、この座具によれば、座具の表裏両方向へラグスクリューをねじ込むことができるので、座具を挟んで表裏両側の接合面に接合面を密着させた木質部材同士を接合することが可能になる。 Furthermore, when the sitting tool is used for the joining structure of the wooden members, the lag screw is passed through the through hole penetrating the opposite surface in the direction perpendicular to one of the seat surfaces on the front and back sides, and the other seat surface. The lug screw is passed through a through-hole penetrating the opposite surface in the direction perpendicular to the wood and screwed into the wooden member. That is, according to this sitting tool, the lug screw can be screwed in both the front and back directions of the sitting tool, so that it is possible to join the wooden members having the bonding surfaces in close contact with the bonding surfaces on both the front and back surfaces with the sitting tool interposed therebetween. become.

また、従来のように連結ボルト一本当たり、二個の座具とナットを使用して固定する構造と比較して、施工の手間が軽減され、木軸構造体を施工するに当たり、迅速な施工が可能になる。 In addition, compared to the conventional structure that uses two seating fixtures and nuts to fix each connection bolt, the construction effort is reduced, and the construction of the wooden shaft structure is quicker. Is possible.

（３）本発明の座具は、前記通し孔が、前記通し孔の配列方向へ交互に異なる表裏両側の前記座面に設けられるよう配置されている構成とすることもできる。 (3) The sitting tool of the present invention may be configured such that the through holes are provided on the seating surfaces on both front and back sides that are alternately different in the arrangement direction of the through holes.

この場合は、通し孔に通して木質部材に斜めにラグスクリューをねじ込む際に、配列方向において交互に逆傾斜となるようにねじ込むことが可能になる。これによれば、平行にねじ込まれるラグスクリューの間隔を、一本分だけ広げることができ、ラグスクリュー間の木質部分の強度を充分に確保することができる。よって、施工後の木質部材の割れや亀裂の発生を抑制することが可能で、構築物としての安全性を高めるために、より好ましい。 In this case, when the lag screw is obliquely screwed into the wooden member through the through hole, it can be screwed so as to be alternately inclined in the arrangement direction. According to this, the space | interval of the lag screw screwed in parallel can be expanded only by one, and the intensity | strength of the wooden part between lag screws can fully be ensured. Therefore, it is possible to suppress the occurrence of cracks and cracks in the wooden member after construction, and it is more preferable in order to increase the safety as a structure.

（４）上記の目的を達成するため、本発明は、複数の可動腕部を有する接合具と、前記可動腕部の先端に取り付けられており、長方形で平板状の座具本体と、該座具本体の相対する位置にある一組の端縁部の接合面に形成され、先端縁へ向け板厚が薄くなるよう所要角度で傾斜した平らな座面と、前記座具本体の前記端縁部に設けられ、前記座面から前記座面と直角方向に反対の面に貫通した、ラグスクリューを通すための所要数の通し孔とを備える座具と、接合面を前記座具の接合面に当接し、前記接合面と所要角度を以て所要深さに形成された下穴を有している木質部材と、前記座具の前記通し孔から前記木質部材の前記下穴に通すようにねじ込まれ、前記座具と前記木質部材を接合しているラグスクリューとを備える木質部材の接合構造である。 (4) In order to achieve the above object, the present invention provides a connector having a plurality of movable arm portions, a rectangular flat plate seat body attached to the distal end of the movable arm portion, and the seat. A flat seating surface formed at a joint surface of a pair of end edges at opposite positions of the fixture body and inclined at a required angle so that the plate thickness decreases toward the tip edge, and the edge of the seat fixture body A seating tool provided with a required number of through holes for passing a lag screw, which is provided in a section and penetrates from the seating surface to a surface opposite to the seating surface in a direction perpendicular to the seating surface; A wood member having a prepared hole formed at a required depth at a required angle with the joint surface, and screwed to pass from the through hole of the sitting tool to the prepared hole of the wooden member. A wood member joining structure comprising: the sitting tool and a lag screw joining the wood member It is.

本発明に係る木質部材の接合構造は、接合具に複数の可動腕部を備えており、その先端に取り付けられている座具に、あらかじめ設けてある下穴にラグスクリューをねじ込んで、木質部材を接合することができる。したがって、複数の木質部材を、接合具を中心として、異なる方向へ配する施工を行うことができ、主に木質部材同士を接合するだけの従来の施工形態のバリエーションを、より広げることが可能になる。なお、座具に係る各作用については、前記（１）に記載した説明と同様であるので、ここでは省略する。 The wood member joining structure according to the present invention includes a plurality of movable arm portions in the joint, and a lug screw is screwed into a prepared hole provided in advance in a seat attached to the tip of the joint. Can be joined. Therefore, it is possible to perform construction in which multiple wooden members are arranged in different directions with the joint as the center, and it is possible to further expand the variation of the conventional construction form that mainly joins wooden members together Become. In addition, about each effect | action which concerns on a sitting tool, since it is the same as that of the description described in said (1), it abbreviate | omits here.

（５）上記の目的を達成するため、本発明は、中心軸を同一直線に合わせて配され、接合面と所要角度を以て所要深さに形成された下穴を有している一組の木質部材と、各木質部材の接合面で挟まれており、長方形で平板状の座具本体と、該座具本体の相対する位置にある一組の端縁部の表裏両側の接合面に形成され、先端縁へ向け板厚が薄くなるよう所要角度で傾斜した平らな座面と、前記座具本体の前記端縁部に設けられ、表裏両側の前記座面のうち一方の座面と直角方向に反対の面に貫通した、ラグスクリューを通すための所要数の通し孔、及び他方の座面と直角方向に反対の面に貫通した、ラグスクリューを通すための所要数の通し孔とを備える座具と、該座具の前記通し孔から前記各木質部材の前記下穴に通すようにねじ込まれ、前記木質部材同士を接合しているラグスクリューとを備える木質部材の接合構造である。 (5) In order to achieve the above object, the present invention provides a set of woods having a pilot hole that is arranged with the central axis aligned with the same straight line and formed at a required depth with a required angle with the joint surface. It is sandwiched between the members and the joint surfaces of the wooden members, and is formed on the joint surfaces on both the front and back sides of a pair of end edges located at opposite positions of the rectangular and flat plate-like seat body. A flat seat surface inclined at a required angle so that the plate thickness is reduced toward the tip edge, and provided at the end edge portion of the seat body, and perpendicular to one of the seat surfaces on both sides And a required number of through-holes for passing the lag screw, and a required number of through-holes for passing the lag screw perpendicularly to the other seating surface. A seating tool and screwed to pass through the through hole of the seating tool to the pilot hole of each wooden member; Serial is a joint structure of the wood member and a lag screw that joins the wood members together.

本発明に係る木質部材の接合構造は、接合する木質部材を、中心軸を同一直線に合わせて配することで、各木質部材をずれのない状態とすることができる。そして、木質部材の接合構造を施工するに際して、座具には、表裏両側の座面のうち一方の座面と直角方向に反対の面に貫通した通し孔にラグスクリューが通され、他方の座面と直角方向に反対の面に貫通した通し孔にラグスクリューが通されて木質部材にねじ込まれる。 In the wood member joining structure according to the present invention, the wood members to be joined can be placed in a state in which there is no deviation by arranging the wood members to be joined with the central axis aligned with the same straight line. Then, when constructing the joining structure of the wooden members, the lag screw is passed through the through hole penetrating the surface opposite to the one of the seat surfaces on both sides of the seat member in the direction perpendicular to the seat surface, and the other seat. A lag screw is passed through a through-hole penetrating the opposite surface in the direction perpendicular to the surface and screwed into the wood member.

すなわち、座具の表裏両方向へラグスクリューをねじ込むことができるので、座具を挟んで表裏両側の接合面に接合面を密着させた木質部材同士を接合することが可能になる。なお、座具に係る各作用については、前記（２）に記載した説明と同様であるので、ここでは省略する。 That is, since the lag screw can be screwed in both the front and back sides of the sitting tool, it is possible to join the wood members having the bonding surfaces in close contact with the joining surfaces on both the front and back sides with the sitting tool interposed therebetween. In addition, about each effect | action which concerns on a sitting tool, since it is the same as that of the description described in said (2), it abbreviate | omits here.

（６）本発明の木質部材の接合構造は、前記木質部材の前記接合面に、少なくとも施工時に下側となる前記接合面を密着させて、前記座具を収容する収容凹部が形成されている構成としてもよい。 (6) In the wood member joining structure of the present invention, an accommodation recess for housing the seating tool is formed by bringing the joining surface of the wood member into close contact with at least the lower joining surface during construction. It is good also as a structure.

この場合は、施工後の構造体の接合部を下方から見たときに、木質部材の下側が密着しているので、仮に座具が側面に露出しているとしても、見えにくい。また、座具の座面に位置する、ラグスクリューのヘッドも、同様に見えにくくなっている。したがって、木質部材に金属製の部品の露出がなく、積極的に木質の構造体を見せる上で、意匠的に、より好ましい形態とすることができる。 In this case, when the joined portion of the structure after construction is viewed from below, the lower side of the wooden member is in close contact, so even if the sitting tool is exposed to the side, it is difficult to see. Also, the head of the lag screw located on the seat surface of the sitting tool is similarly difficult to see. Therefore, there is no exposure of metal parts on the wooden member, and it is possible to obtain a more preferable form in terms of design when actively showing a wooden structure.

（７）本発明の木質部材の接合構造は、前記木質部材に、他方の木質部材の下穴と対応し方向を同じくして設けられた、ラグスクリューを入れる入れ孔が形成されている構成としてもよい。 (7) The wood member joining structure of the present invention has a structure in which the wood member is provided with a slot for inserting a lag screw provided in the same direction as the other wood member corresponding to the prepared hole. Also good.

この場合は、入れ孔にラグスクリューのヘッドが収まることになるので、仮に木質部材の施工時に下側となる部分にラグスクリューのヘッドが位置する場合でも、施工後の構造体の接合部を下方から見たときに、座具やラグスクリューは見えにくい。 In this case, since the head of the lag screw will fit in the insertion hole, even if the head of the lag screw is located in the lower part when constructing the wooden member, the joint part of the structure after construction is moved downward It is difficult to see the sitting tool and lag screw when viewed from above.

（８）上記の目的を達成するため、本発明は、複数の可動腕部を有する接合具の前記可動腕部の先端に取り付けた、長方形で平板状の座具本体と、該座具本体の相対する位置にある一組の端縁部の接合面に形成され、先端縁へ向け板厚が薄くなるよう所要角度で傾斜した平らな座面と、前記座具本体の前記端縁部に設けられ、前記座面から前記座面と直角方向に反対の面に貫通した、ラグスクリューを通すための所要数の通し孔とを備える座具の前記接合面に、前記接合面と所要角度を以て所要深さに形成された下穴を有している木質部材の接合面を当接し、前記座具の前記通し孔から前記木質部材の前記下穴に通すようにラグスクリューをねじ込んで固定し、前記座具と前記木質部材を接合する木質部材の接合方法である。 (8) In order to achieve the above object, the present invention provides a rectangular flat plate seat body attached to the distal end of the movable arm portion of a connector having a plurality of movable arm portions, A flat seat surface formed at a joint surface of a pair of end edges located at opposite positions and inclined at a required angle so that the plate thickness decreases toward the tip edge, and provided at the end edge of the seat body The seating surface of the seating tool having a required number of through holes for passing the lag screw, which penetrates from the seating surface to a surface opposite to the seating surface in a direction perpendicular to the seating surface, is required with the jointing surface and a required angle. Abutting the joint surface of the wooden member having a pilot hole formed to a depth, and fixing by screwing a lag screw so as to pass from the through hole of the sitting tool to the pilot hole of the wooden member; It is the joining method of the wooden member which joins a sitting tool and the said wooden member.

本発明に係る木質部材の接合方法は、複数の木質部材を、接合具を中心として、異なる方向へ配する施工を行うことができ、主に木質部材同士を接合するだけの従来の施工形態のバリエーションを、より広げることが可能になる。なお、座具に係る各作用については、前記（１）に記載した説明と同様であるので、ここでは省略する。 The method of joining wooden members according to the present invention can perform construction in which a plurality of wooden members are arranged in different directions with a joint as a center, and the conventional construction mode mainly involves joining together wooden members. Variations can be expanded further. In addition, about each effect | action which concerns on a sitting tool, since it is the same as that of the description described in said (1), it abbreviate | omits here.

（９）上記の目的を達成するため、本発明は、接合部に接合面と所要角度を以て所要深さに形成された下穴を有し、前記接合面と下穴の角度は、平行な表裏両面に対する通し孔の角度と同じに設定されている一組の木質部材を、中心軸を同一直線に合わせて配する工程と、各木質部材の接合面の間に、長方形で平板状の座具本体と、該座具本体の相対する位置にある一組の端縁部の表裏両側の接合面に形成され、先端縁へ向け板厚が薄くなるよう所要角度で傾斜した平らな座面と、前記座具本体の前記端縁部に設けられ、表裏両側の前記座面のうち一方の座面と直角方向に反対の面に貫通した、ラグスクリューを通すための所要数の通し孔、及び他方の座面と直角方向に反対の面に貫通した、ラグスクリューを通すための所要数の通し孔とを備える座具を挟む工程と、各通し孔から、各通し孔に対応する位置にある各下穴に通すようにラグスクリューをねじ込んで固定し、各木質部材を連結する工程とを備える木質部材の接合方法である。 (9) In order to achieve the above-mentioned object, the present invention has a pilot hole formed at a required depth with a required angle with a bonded surface in a bonded portion, and the angle between the bonded surface and the lower hole is parallel to the front and back.

図２、図３に示す木質部材の接合構造Ｃ１は、座具１とラグスクリュー４を使用して、木質部材２、３を接合した構造である。なお、ラグスクリュー４は、六角のボルトヘッド様のヘッドを有する大きな木ねじ様のものであるが、特に限定するものではなく、同様の作用を有するものであれば、他の木ネジ様のネジ等を代用することも可能である。 Please refer to FIG. 2 and FIG.
The wood member joining structure C1 shown in FIGS. 2 and 3 is a structure in which the wood members 2 and 3 are joined using the sitting tool 1 and the lag screw 4. The lag screw 4 is a large wood screw-like one having a hexagonal bolt head-like head, but is not particularly limited. Can be substituted.

木質部材の接合構造Ｃ１では、角材である木質部材２、３が中心軸を同一直線に合わせて配されている。木質部材２、３は、一方の正方形の木口が接合面２００、３００である。木質部材２、３は、接合面２００、３００から木部内部へ所要角度を以て所要深さに形成された下穴２４、２４ａ、及び下穴３４、３４ａを有している。 In the wood member joining structure C1, the wood members 2 and 3 which are square members are arranged with their central axes aligned with the same straight line. In the wooden members 2 and 3, one square end is the joint surfaces 200 and 300. The wood members 2 and 3 have pilot holes 24 and 24a and pilot holes 34 and 34a formed from the joint surfaces 200 and 300 to the inside of the timber at a required depth with a required angle.

木質部材２の下穴２４、２４ａは、接合面２００に対し、６８°の角度で互いに平行に、かつ投影状態で交差する方向へ、すなわち逆傾斜で形成されており、それぞれラグスクリュー４とほぼ同じ長さを有している。また、同様に、木質部材３の下穴３４、３４ａは、接合面３００に対し、６８°の角度で互いに平行に、かつ投影状態で交差する方向へ、すなわち逆傾斜で形成されており、それぞれラグスクリュー４とほぼ同じ長さを有している。 The lower holes 24, 24a of the wood member 2 are formed in parallel to each other at an angle of 68 ° with respect to the joint surface 200 and in a direction intersecting in a projected state, that is, in a reverse inclination. Have the same length. Similarly, the pilot holes 34 and 34a of the wooden member 3 are formed in parallel to each other at an angle of 68 ° with respect to the joint surface 300 and in a direction intersecting in a projected state, that is, in a reverse inclination. It has substantially the same length as the lag screw 4.

なお、各下穴の角度は、上記に限定されるものではなく、木質部材２、３の中に収まる範囲内において、適宜設定することが可能である。また、下穴の本数も特に限定せず、下穴の間の木質部の強度を充分に確保できる範囲内において、適宜設定することが可能である。これについては、後述する木質部材の接合構造Ｃ２、Ｃ３の場合でも同様である。 The angle of each pilot hole is not limited to the above, and can be set as appropriate within a range that can be accommodated in the wooden members 2 and 3. Further, the number of pilot holes is not particularly limited, and can be appropriately set within a range in which the strength of the wood portion between the pilot holes can be sufficiently secured. The same applies to the case of the wood member joining structures C2 and C3 described later.

また、木質部材２、３の接合面２００、３００側には、接合面２００、３００間に座具１を挟んで対向させたとき、各下穴２４、２４ａ、及び下穴３４、３４ａと同一直線上で切り欠かれた構造であり、他方の木質部材の下穴と対応し方向を同じくして設けられた入れ孔２２、３２が形成されている。 Further, when the seating tool 1 is sandwiched between the joint surfaces 200 and 300 on the side of the joint surfaces 200 and 300 of the wooden members 2 and 3, the same as the pilot holes 24 and 24a and the pilot holes 34 and 34a, respectively. The structure has a structure that is cut out on a straight line, and is formed with insertion holes 22 and 32 that are provided in the same direction corresponding to the prepared holes of the other wooden member.

入れ口２２は、木質部材２の接合面２００から一方の側面２０１にかけて二箇所に設けられ、接合面２００から他方の側面２０２にかけて二箇所に設けられている。また、入れ口３２は、木質部材３の接合面３００から一方の側面３０１にかけて二箇所に設けられ、接合面３００から他方の側面３０２にかけて二箇所に設けられている。 The inlets 22 are provided at two locations from the joint surface 200 of the wood member 2 to the one side surface 201, and are provided at two locations from the joint surface 200 to the other side surface 202. The inlets 32 are provided at two locations from the joint surface 300 of the wood member 3 to the one side surface 301 and are provided at two locations from the joint surface 300 to the other side surface 302.

そして、各入れ孔２２、３２からは、ラグスクリュー４が入れられて、座具１の通し孔１３０、１４０、１５０、１６０を通り、対応する下穴２４、２４ａ、３４、３４ａにねじ込まれる。各ラグスクリュー４は、ヘッド４０が各座面１３、１４、１５、１６に圧接されるようにねじ込まれ、木質部材２、３は、座具１と各ラグスクリュー４によって接合されている。 Then, the lag screw 4 is inserted from each of the insertion holes 22 and 32, passes through the through holes 130, 140, 150 and 160 of the sitting tool 1, and is screwed into the corresponding prepared holes 24, 24 a, 34 and 34 a. Each lag screw 4 is screwed so that the head 40 is pressed against each seating surface 13, 14, 15, 16, and the wooden members 2, 3 are joined to the sitting tool 1 by each lag screw 4.

（作用）
まず、座具１は、長方形で平板状の座具本体１０の相対する位置にある一組の端縁部の表裏両側の接合面１１、１２に、先端縁へ向け板厚が薄くなるよう傾斜した平らな座面１３、１４、及び座面１５、１６を有しているので、各座面１３、１４、１５、１６に設けられる通し孔１３０、１４０、１５０、１６０の配列方向を、座具１の両側の端縁部で平行にすることができる。これによれば、ラグスクリュー４の位置が揃うので、施工がしやすくなり、接合強度の向上にも寄与できる。 (Function)
First, the sitting tool 1 is inclined so that the plate thickness decreases toward the tip edge on the joint surfaces 11 and 12 on both sides of the pair of end edges at the opposing positions of the rectangular and flat sitting body 10. Flat seating surfaces 13 and 14 and seating surfaces 15 and 16, the arrangement direction of the through holes 130, 140, 150 and 160 provided in the respective seating surfaces 13, 14, 15 and 16 is determined according to the seating direction. It can be made parallel in the edge part of the both sides of the tool 1. FIG. According to this, since the position of the lag screw 4 is aligned, it becomes easy to perform the construction and can contribute to the improvement of the bonding strength.

また、座面１３、１４、及び座面１５、１６は、ラグスクリュー４を木質部材２、３の接合面２００、３００に斜めにねじ込んだ際に、ラグスクリュー４が有するヘッド４０が圧着する部分となる。更に、座面１３、１４、及び座面１５、１６は、各接合面２００、３００に対して傾斜しており、このため接合面２００、３００に密着する木質部材２、３の接合面に対しても傾斜するので、ラグスクリュー４を通し孔１３０、１４０、１５０、１６０に通して木質部材２、３に斜めにねじ込んだときに、ヘッド４０の圧着面と座面１３、１４、及び座面１５、１６は隙間なく平行に密着し、これにより最大面積で均等な圧力を以て密着する。 The seat surfaces 13 and 14 and the seat surfaces 15 and 16 are portions to which the head 40 of the lag screw 4 is pressure-bonded when the lag screw 4 is obliquely screwed into the joining surfaces 200 and 300 of the wooden members 2 and 3. It becomes. Furthermore, the seating surfaces 13 and 14 and the seating surfaces 15 and 16 are inclined with respect to the joining surfaces 200 and 300, and therefore, with respect to the joining surfaces of the wooden members 2 and 3 that are in close contact with the joining surfaces 200 and 300. However, when the lag screw 4 is passed through the through-holes 130, 140, 150, 160 and is screwed into the wooden members 2, 3, the pressure bonding surface of the head 40 and the seat surfaces 13, 14, and the seat surface 15 and 16 are closely contacted in parallel without a gap, thereby being closely contacted with a uniform pressure in the maximum area.

更に、座具１は、木質部材の接合構造Ｃ１に使用した際に、表裏両側の座面１３、１４、及び座面１５、１６のうち一方の座面１３、１５と直角方向に反対の面に貫通した通し孔１３０、１５０にラグスクリュー４を通し、他方の座面１４、１６と直角方向に反対の面に貫通した通し孔１４０、１６０にラグスクリュー４を通して、木質部材２、３にねじ込まれる。 Further, when the sitting tool 1 is used for the wood member joining structure C1, the surface opposite to the one of the seating surfaces 13, 15 on the front and back sides and the seating surfaces 15, 16 in the direction perpendicular to the one. The lug screw 4 is passed through the through-holes 130 and 150 penetrating through the lug, and the lug screw 4 is passed through the through-holes 140 and 160 penetrating through the opposite face of the other seating surface 14 and 16 into the wood members 2 and 3. It is.

すなわち、この座具１によれば、座具１の表裏両方向へラグスクリュー４をねじ込むことができるので、座具１を挟んで表裏両側の接合面１１、１２に接合面２００、３００を密着させた木質部材２、３同士を接合することが可能になる。また、従来のように連結ボルト一本当たり、二個の座具とナットを使用して固定する構造と比較して、施工の手間が軽減され、木軸構造体を施工するに当たり、迅速な施工が可能になる。 That is, according to this sitting tool 1, since the lag screw 4 can be screwed in both the front and back sides of the sitting tool 1, the bonding surfaces 200 and 300 are brought into close contact with the bonding surfaces 11 and 12 on both sides of the sitting tool 1. The wood members 2 and 3 can be joined together. In addition, compared to the conventional structure that uses two seating fixtures and nuts to fix each connection bolt, the construction effort is reduced, and the construction of the wooden shaft structure is quicker. Is possible.

更に、座具１は、通し孔１３０、１４０、１５０、１６０が、通し孔の配列方向へ交互に異なる表裏両側の座面に設けられるよう配置されているので、通し孔に通して木質部材２、３の接合面２００、３００に斜めにラグスクリュー４をねじ込む際に、配列方向において交互に逆傾斜となるようにねじ込むことが可能になる。 Furthermore, since the sitting tool 1 is arranged so that the through holes 130, 140, 150, 160 are provided on the seating surfaces on both the front and back sides that are alternately different in the arrangement direction of the through holes, the wooden member 2 is passed through the through holes. When the lag screw 4 is screwed into the three joint surfaces 200 and 300 obliquely, it can be screwed so as to be alternately inclined in the arrangement direction.

これによれば、水平方向に平行にねじ込まれるラグスクリュー４の間隔を、一本分だけ広げることができ、ラグスクリュー４間の木質部分の強度を充分に確保することができる。よって、施工後の木質部材２、３の割れや亀裂の発生を抑制することが可能で、構築物としての安全性を、より高めることができる。 According to this, the space | interval of the lag screw 4 screwed in parallel in a horizontal direction can be extended only by one, and the intensity | strength of the wood part between the lag screws 4 can fully be ensured. Therefore, it is possible to suppress the occurrence of cracks and cracks in the wooden members 2 and 3 after construction, and the safety as a structure can be further enhanced.

また、木質部材の接合構造Ｃ１は、接合する木質部材２、３を、中心軸を同一直線に合わせて配することで、各木質部材２、３をずれのない状態とすることができる。そして、木質部材の接合構造Ｃ１を施工するに際して、座具１には、表裏両側の座面１３、１４、１５、１６のうち一方の座面１３、１５と直角方向に反対の面に貫通した通し孔１３０、１５０にラグスクリュー４が通され、他方の座面１４、１６と直角方向に反対の面に貫通した通し孔１４０、１６０にラグスクリュー４が通されて木質部材２、３にねじ込まれる。これにより、座具１の表裏両方向へラグスクリュー４をねじ込むことができるので、座具１を挟んで表裏両側の接合面１１、１２に接合面２００、３００を密着させた木質部材２、３を接合することが可能になる。 Further, in the wood member joining structure C1, the wood members 2 and 3 to be joined can be placed in a state in which the wood members 2 and 3 are not displaced by arranging the wood members 2 and 3 to be joined with their central axes aligned with the same straight line. And when constructing the joining structure C1 of the wooden member, the sitting tool 1 penetrated through the opposite surface in the direction perpendicular to one of the seating surfaces 13, 14, 15 and 16 on both sides of the front and back. The lag screw 4 is passed through the through holes 130, 150, and the lag screw 4 is passed through the through holes 140, 160 penetrating the surface opposite to the other seating surfaces 14, 16 and screwed into the wood members 2, 3. It is. Thereby, since the lag screw 4 can be screwed in both the front and back directions of the sitting tool 1, the wooden members 2, 3 in which the joining surfaces 200, 300 are brought into close contact with the joining surfaces 11, 12 on both sides of the sitting tool 1 are sandwiched. It becomes possible to join.

また、本実施の形態のラグスクリュー４を使用する接合構造は、木質部材２、３を座具１を介し接面させた後で、ラグスクリュー４によって固定するようになっているので、接合する木質部材の順序に関係なく接合でき、建て方施工が、容易である。 Moreover, since the joining structure which uses the lag screw 4 of this Embodiment makes the wooden members 2 and 3 contact the surface via the sitting tool 1, it fixes with the lag screw 4, so it joins. It can be joined regardless of the order of the wooden members, and construction is easy.

施工状態においては、ラグスクリューボルト４が木繊維方向と交差しているので、木質部材の割れに対して拘束力が良好であり、強度に優れ、安全性も高い。また、木質部材の鉛直剪断力に抵抗するだけでなく、木材繊維方向とラグスクリュー４が交差することで、引き抜き強度が増大する。 In the construction state, since the lag screw bolt 4 intersects the wood fiber direction, the restraining force is good with respect to the cracking of the wooden member, the strength is excellent, and the safety is high. In addition to resisting the vertical shearing force of the wooden member, the pulling strength is increased by crossing the wood fiber direction and the lag screw 4.

木質部材の接合部の木口にラグスクリュー４を一方向に一定間隔を開けることで、ラグスクリュー４の応力作用点を分散させて、接合耐力の増大を図ることができる。更には、座具１またはラグスクリュー４のヘッド４０が、木質部材の内側に隠れて、側面からあまりはみ出さないので、金属部品が露出しにくく、意匠性に優れる。 By opening the lag screw 4 at a fixed interval in one direction at the mouth of the joint portion of the wooden member, the stress acting point of the lag screw 4 can be dispersed to increase the bonding strength. Furthermore, since the head 40 of the sitting tool 1 or the lag screw 4 is hidden behind the wooden member and does not protrude so much from the side surface, the metal parts are hardly exposed and the design is excellent.

The pilot holes 80 are formed in parallel to each other at an angle of 68 ° with respect to the joint surface 800 and in a direction intersecting in a projected state, that is, with a reverse inclination, and each has substantially the same length as the lag screw 4. ing.

そして、座具５の接合面５３に木質部材８の木口である正方形の接合面８００が当接され、座具５の通し孔５１０、５２０を通り、対応する下穴８０にねじ込まれる。各ラグスクリュー４は、ヘッド４０が各座面５１、５２に圧接されるようにねじ込まれ、木質部材８は、座具５と各ラグスクリュー４によって連結され、各木質部材８は接合具６を介し接合されている。 Then, a square joint surface 800 which is a lip of the wooden member 8 is brought into contact with the joint surface 53 of the sitting tool 5, passes through the through holes 510 and 520 of the sitting tool 5, and is screwed into the corresponding prepared hole 80. Each lag screw 4 is screwed so that the head 40 is pressed against each seating surface 51, 52, and the wooden member 8 is connected by the sitting tool 5 and each lag screw 4, and each wooden member 8 connects the connector 6. Are joined together.

（作用）
木質部材の接合構造Ｃ２に使用される座具５は、長方形で平板状の座具本体５０の相対する位置にある一組の端縁部の接合面５３と反対の面に、先端縁へ向け板厚が薄くなるよう所要角度で傾斜した平らな座面５１、５２を有しているので、座面５１、５２に設けられる通し孔５１０、５２０の配列方向を、座具５の両側の端縁部で平行にすることができる。これによれば、ラグスクリュー４の位置が揃うので、施工がしやすくなり、接合強度の向上にも寄与できる。 (Function)
The sitting tool 5 used in the wood member joining structure C2 is directed toward the tip edge on a surface opposite to the joining surface 53 of the pair of end edges at the opposing positions of the rectangular flat plate seat body 50. Since the flat seating surfaces 51 and 52 are inclined at a required angle so that the plate thickness is reduced, the arrangement direction of the through holes 510 and 520 provided in the seating surfaces 51 and 52 is set to the ends on both sides of the seating fixture 5. It can be parallel at the edges. According to this, since the position of the lag screw 4 is aligned, it becomes easy to perform the construction and can contribute to the improvement of the bonding strength.

また、座面５１、５２は、ラグスクリュー４を木質部材８に斜めにねじ込んだ際に、ラグスクリュー４が有するヘッド４０が圧着する部分となる。更に、座面５１、５２は、反対側の接合面５３に対して傾斜しており、このため接合面５３に密着する木質部材８の接合面８００に対しても傾斜するので、ラグスクリュー４を木質部材８に斜めにねじ込んだときにヘッド４０の圧着面と座面５１、５２は隙間なく平行に密着し、これにより最大面積で均等な圧力を以て密着する。 Further, the seat surfaces 51 and 52 are portions to which the head 40 of the lag screw 4 is pressure-bonded when the lag screw 4 is obliquely screwed into the wooden member 8. Furthermore, the seating surfaces 51 and 52 are inclined with respect to the opposite joining surface 53, and thus are also inclined with respect to the joining surface 800 of the wood member 8 that is in close contact with the joining surface 53. When screwed into the wooden member 8 at an angle, the pressure-bonding surface of the head 40 and the seating surfaces 51 and 52 are in close contact with each other without any gap, and thereby are in close contact with the maximum area with uniform pressure.

更に、座具５は、木質部材の接合構造Ｃ２に使用した際に、ラグスクリュー４を座具５の通し孔５１０、５２０に通し、木質部材８の接合面８００に斜めにねじ込むことで、木質部材８との接合が可能になるので、従来のように連結ボルト一本当たり、二個の座具とナットを使用して固定する構造と比較して、施工の手間が軽減され、木軸構造体を施工するに当たり、迅速な施工が可能になる。 Furthermore, when the sitting tool 5 is used for the wood member joining structure C2, the lug screw 4 is passed through the through holes 510 and 520 of the seating tool 5 and obliquely screwed into the joining surface 800 of the wood member 8, thereby Since joining with the member 8 is possible, compared to the conventional structure in which two seating fixtures and nuts are used for fixing each connecting bolt, the construction work is reduced, and the wooden shaft structure is reduced. When constructing the body, rapid construction becomes possible.

そして、木質部材の接合構造Ｃ２は、接合具６に二本の可動腕部６０を備えており、その先端に取り付けられている座具５に、あらかじめ設けてある下穴８０にラグスクリュー４をねじ込んで、木質部材８を接合することができる。これにより、二本の木質部材８を、接合具６を中心として、異なる方向へ配する施工を行うことができ、主に木質部材同士を接合するだけの従来の施工形態のバリエーションを、より広げることが可能になる。 And the joining structure C2 of a wooden member equips the joining tool 6 with the two movable arm parts 60, and attaches the lag screw 4 to the pilot hole 80 provided beforehand in the sitting tool 5 attached to the front-end | tip. The wood member 8 can be joined by screwing. Thereby, the construction which distributes the two wooden members 8 in different directions with the joint 6 as a center can be performed, and the variation of the conventional construction form which mainly joins the wooden members is further expanded. It becomes possible.
