【発明の属する技術分野】
本発明は例えば柱や、土台、梁、桁等の主幹部材に、火打ちばりや、方づえ、筋かい、合掌、或いは出隅、入隅等に設ける隅木部材に取付けるもや材等の接合部材を、斜めに連結するための木造建築部材の連結具に関する。
【０００２】
【従来の技術】
上記した種類の木造建築部材の連結構造は、主幹部材に形成した堀込みに、接合部材の端部を嵌込み、ボルト、ナットや、かすがいで連結する構造が従来より知られている。ところが、堀込みの加工は高度な技術を必要とする厄介な作業であり、腕の立つ職人が不足している現状もあって、加工の容易な連結構造が建築業界で望まれている。また、堀込みを形成すると、その部分の太さがその他の箇所に比べて格段に細くなり、木材の強度が大巾に低下するため、太い木材を用いないと十分な強度が得られないものであった。
【０００３】
【発明が解決しようとする課題】
本発明は上記実情に鑑みて成されたものであり、その目的とするところは、木材の連結部分に施す加工を容易に行えると共に、加工を施した後も木材の強度を良好な状態に保持できる木造建築部材の連結具を提供することである。
【０００４】
【課題を解決するための手段】
上記目的を達成するために、本発明のうち請求項１記載の発明は、主幹部材に接合部材の端面を当接する状態で斜めに連結する為に、両者の内部に収納された状態で締結手段によって固定される木造建築部材の連結具であって、接合部材の接合面に設けた係合溝に嵌まり込む接続片と、主幹部材若しくは接合部材の接合面に設けた凹部に嵌まり込む状態で接続片の端部に屈折して連続する支持片と、主幹部材の接合面に設けた嵌合穴に嵌まり込む状態で支持片から突設する突起体と、から構成してあることを特徴とする木造建築部材の連結具である。主幹部材とは柱や、土台、梁、桁等から成るものである。接合部材とは火打ちばりや、方づえ、筋かい、合掌、或いは出隅、入隅等に設ける隅木部材に取付けるもや材等から成るものである。締結手段はボルト、ナットを少なくとも備えるものである。接続片は接続片より僅かに幅広の係合溝内にがたつきなく収納される状態となる。突起体は突起体の径より僅かに大きな嵌合穴にがたつきなく収納される状態となる。
【０００５】
【０００６】
請求項２記載の発明は、主幹部材の一部に二本の接合部材の端面を当接する状態で斜めに連結する為に、三者の内部に収納された状態で締結手段によって固定される木造建築部材の連結具であって、Ｖ字型に交差する二本の接合部材の各接合面に設けた係合溝に嵌まり込むＶ字型に連続する二枚の接続片と、主幹部材の接合面に設けた嵌合穴に嵌まり込む状態で両接続片が連続する部分から突設する突起体と、から構成してあることを特徴とする。主幹部材に二本の接合部材を連結した状態は略「Ｋ」字型となる。
【０００７】
木造建築部材の連結具はＶ字型に連続する二枚の接続片と、両接続片が連続する部分から突設する突起体と、から構成する構造に限らず、請求項３記載の発明のように、主幹部材若しくは接合部材の接合面に設けた凹部に嵌まり込む支持片と、支持片の対向する両端部から「ハ」字型に突出する二枚の接続片と、支持片から突設する突起体と、から構成しても良い。

【００１１】
【００１２】
【発明の実施の形態】
木造建築部材の連結構造の第一実施形態は図１に示すように、直交する梁及び桁からなる二本の主幹部材１，１と、火打ちばりからなる接合部材２と、両主幹部材１，１の隅角部分に接合部材２を斜めに連結する為の連結具３と、連結具３を主幹部材１並びに接合部材２に夫々固定する締結手段９１、９２とから構成されている。
【００１３】
連結具３は図１〜図４に示してあり、そのうちの図４（イ）に基づいて説明すれば、右肩上がりに傾斜する長方形状の接続片４と、接続片４の下辺端部の中間部から下向きに突設したカップ状の突起体５とから構成される金属製品である。接続片４と突起体５を一体にする手段は、接続片４の下辺端部の中間部に、突起体５の周壁の端面の対向箇所を、押し当てた状態で強固に溶接することによって行われている。火打ちばりは梁や桁に約４５度の角度で連結する構造が一般的であるので、突起体５に対して接続片４を約４５度の角度で傾斜してある。また、連結具３は接続片４の突出方向が接合部材２の連結方向となるが、突起体５を中心にして１８０度回転させれば、右肩上がりに傾斜する状態の接続片４が、左肩上がりに傾斜する状態になり、これを利用することによって、接合部材２の両端部を同一構造の連結具３で固定できるようにしてある。
【００１４】
接続片４は数ミリの厚みの板体であり、ボルトＢ、ナットＮ、係止ピンＰからなる締結手段９２で接合部材２に固定されるもので、突起体５を設けた下辺の端部には、突起体５を固定する締結手段９１のボルトＢ若しくはナットＮを挿入する為のＵ字型の切欠部４１を備え、突起体５を設けた辺に直交する両辺の対向箇所に、ボルトＢの軸部を引掛けるＵ字型の受孔４２を外部に開口する状態で設けると共に、さらに、上辺の端部には、係止ピンＰを挿通して支持する二つの取付孔４３を対向する箇所に備えている。
【００１５】
突起体５は主幹部材１にボルトＢ、ナットＮからなる締結手段９１で固定されるもので、上向きに開口するカップ形状の内部をボルトＢの頭部若しくはナットＮを収める収納部５１となし、その底壁にボルトＢの軸部を挿通する通孔５２を備えている。なお、収納部５１の径は、ボルトＢの頭部、若しくはナットＮの径の大きさより僅かに大きい程度であっても良いし、ボルトＢの頭部、若しくはナットＮに嵌め込んで締付ける工具が入る大きさに形成してあっても良い。
【００１６】
主幹部材１は図２に示すように、その側面には、接合部材２の端面が当接する接合面の中央部分に、前記突起体５を嵌込む円盤形の嵌合穴１１を備え、嵌合穴１１の底面には、突起体５の通孔５２に対応する箇所に、ボルトＢの軸部を挿通する抜孔１２を、反対面に貫通して設けてある。
【００１７】
接合部材２は主幹部材１の側面に当接する接合面である両端面を、長手方向に対して傾斜して形成してあり、各端面には、接続片４を嵌込む係合溝２１を、主幹部材１と接合部材２の両長手方向に直交する方向に貫通し且つ接合部材２の長手方向を深さ方向とする状態で設けてある。また、接合部材２の側面には、前記した二つの受孔４２の一つ（図１で説明すれば、上側の受孔４２）の奥部に対応する箇所に、ボルトＢの軸部を挿通する透孔２２を、係合溝２１を経て反対面に貫通する状態で設けると共に、取付孔４３に対応する箇所に、係止ピンＰを打ち込んで保持する貫通孔２３を設けてある。ところで係合溝２１は、主幹部材１の長手方向に対して平行となる二辺を二等分する箇所に設けることが、接合部材２の強度上最も望ましいが、多少ずれた箇所に設けても何等支障ない。なお、主幹部材１と接合部材２には、丸ノコやドリル等の切削工具を用いて加工を行う。
【００１８】
上記した第一実施形態の組立手順を以下に説明する。まず、各主幹部材１の嵌合穴１１に連結具３の突起体５を夫々嵌込み、接続片４が接合部材２の架設方向を向くように調整した後に、締結手段９１を用い、突起体５の通孔５２から主幹部材１の抜孔１２にボルトＢの軸部を挿通し、ナットＮを締付けて連結具３を固定する。次に、接合部材２の各端部に有する透孔２２に、締結手段９２のボルトＢを夫々挿通して、ナットＮを締付ける。続いて、接続片４の上方から接合部材２を下ろして、接合部材２の係合溝２１に接続片４を嵌め込むようにすると、接合部材２に固定したボルトＢの軸部が、接続片４の受孔４２に引掛っかり、接合部材２が接続片４に支持される。最後に、接合部材２の貫通孔２３から、接続片４の取付孔４３に係止ピンＰを打ち込んで固定する。
【００１９】
上記した組み立て作業は、ボルトＢの軸部が受孔４２に引っ掛かることから、組立作業を一人で行える。また、受孔４２の開口幅は、先部に近付くに連れて徐々に幅広くなるように設けてあるので、接合部材２に固定したボルトＢの軸部を、接続片４の受孔４２に引掛ける作業が行い易くなっている。なお、係止ピンＰは接合部材２から食み出さないように、貫通孔２３と同じか、若しくは幾分短い長さにして、体裁を良くしてある。
【００２０】
図５及び図６は木造建築部材の連結構造の第二実施形態を示すもので、図６を基準に説明すれば、連結具３が、主幹部材１の接合面に当接する水平な支持片６と、支持片６の左端部から左肩下がりに突設する接続片４と、支持片６から上方に突出する突起体５とから構成され、接合部材２の端面に、支持片６を嵌め込む凹部２４を、係合溝２１の入り口部分に連通する状態で備えていることを特徴とするものである。この凹部２４は切削工具を用いて、係合溝２１と同様に、主幹部材１と接合部材２の両長手方向に直交する方向に貫通する状態で設けてある。
【００２１】
木造建築部材の連結構造の第三実施形態は図７及び図８に示すように、柱からなる主幹部材１の一部を中心として、その中心部分に、筋かいからなる四本の接合部材２を放射状に連結する為に、主幹部材１の中心部分の左右両側面に連結具３を夫々固定し、一つの連結具３に対して二つの接合部材２の端部を固定してあることを特徴とするものである。
【００２２】
これに用いる連結具３は、Ｖ字型に連続する二枚の接続片４，４と、両接続片４，４の連続部分から突設した突起体５とから構成してある。各接合部材２はその端部を、頂部が直角な山型に形成し、その頂部から長手方向に沿って係合溝２１を形成し、直交する一組の傾斜面のうち一面を主幹部材１に当接する接合面となし、他面を他の接合部材２に当接する面となすものである。また、主幹部材１の両側面の対向箇所に突起体５を嵌め込む嵌合穴１１を形成してある。
【００２３】
木造建築部材の連結構造の第四実施形態は図９に示すように、大きな接続片４を用いた場合には、連結具３の突起体５を複数個設けると共に、係止ピンＰを保持する取付孔４３を多数設けたことを特徴とするものである。この場合、主幹部材１には、突起体５の数に合わせて嵌合穴１１を設け、接合部材２には、取付孔４３の数に合わせて貫通孔２３を設けておくものである。突起体５は円形の底部を有するカップ形状であっても良いし、方形の底部を有するカップ形状であっても良い。なお、図１０に示すように、接続片４と突起体５は元々別体であり、これを溶接して一体としたものであるが、突起体５を接続片４に強固に溶接するために、突起体５の周壁の対向箇所をＶ字型に切欠き、その切欠いた部分を接続片４の切欠部４１の周縁部に押し当てた状態で溶接することによって、溶接面積を広くして補強してある。この場合、接合部材２の接合面に形成した係合溝２１の入り口側部分を、突起体５の周壁の補強部分を嵌め込む為に切削しておく必要がある。
【００２４】
木造建築部材の連結構造の第五実施形態は図１１及び図１２に示すように、連結具３が長方形状の支持片６と、支持板６の左右両端から「ハ」字型に斜めに突出する二枚の接続片４，４と、該支持片６の中央部から突設する突起体５とから構成してあることを特徴とするもので、この場合、Ｖ字型に連続する二本の接合部材２，２の両接合面に亘って支持片６を嵌め込む凹部２４を形成してある。
【００２５】
木造建築部材の連結構造は上記実施形態に限定されるものではない。例えば、一枚の接続片４と突起体５とから構成される連結具３は、図１では接続片４を接合部材２の架設方向を向くようにすると、接続片４の、主幹部材１に当接する辺が、直立した状態となる構造であったが、この構造に限らず、接続片４を接合部材２の架設方向を向くようにした際に、接続片４の、主幹部材１に当接する辺が、傾斜した状態となる構造や、水平な状態となる構造であっても良く、この場合、接続片４を嵌め込む接合部材２の係合溝２１は、主幹部材１と接合部材２の両長手方向に直交する方向に貫通する状態で設けるのではなく、連結具３の接続片４の傾斜具合に応じて貫通する状態で設けておけば良い。また、一枚の接続片４と突起体５とから構成される連結具３は、接続片４の突出方向が接合部材２の架設方向と完全に一致する状態となるように形成してあるが、多少ずれても良く、この場合、接合部材２の係合溝２１の深さ方向は、接合部材２の長手方向に対して平行ではなく、接続片４の突出方向に応じて設ければ良い。なお、一枚の接続片４と突起体５と支持片６から構成される連結具３も、上記した２通りの構造であっても良く、この場合、支持片６を嵌め込む凹部２４は、主幹部材１若しくは接合部材２の接合面に、支持片６の傾斜具合に応じて貫通する状態で形成しておけば良い。
【００２６】
さらに、連結具３の突起体５に形成した収納部５１内にナットＮを予め溶接して一体として設けておいても良い。また、連結具３は突起体５を接続片４に対して約４５度の角度で斜めに突設してあるが、必ずしもこの突設角度に限定されるものではなく、主幹部材１と接合部材２の連結角度に応じて変えることは何等差し支えない。その他には、接続片４は受孔４２を有しない構造であっても良く、この場合、接続片４を接合部材２に固定する際には、接続片４の取付孔４３と、接合部材２の貫通孔２３を一致させ、その状態を保持しつつ貫通孔２３から取付孔４３にボルトＢの軸部を挿通し、ナットＮを締付けて固定する。
【００２７】
【発明の効果】
請求項２記載の木造建築部材の連結具を使用すれば、主幹部材に接合部材の端面を当接する状態で斜めに連結することができ、しかも、主幹部材と接合部材には、連結具を構成する接続片と突起体の形状に合わせて、嵌合穴や係合溝を形成するだけで良く、その上、嵌合穴や係合溝は切削工具を用いて加工することができるので、両部材に施す加工を簡便に行える。また、嵌合孔や係合溝を形成しても、各部材の太さは加工前と同じであるので、各部材の強度は加工前と遜色のない良好な状態に保持される。
【００２８】
請求項１及び３記載の木造建築部材の連結具を使用すれば、請求項２記載の連結具を使用した場合と同一の効果が得られることに加え、連結具が接続片と突起体に加えて支持片を有しているので、主幹部材若しくは接合部材の接合面に支持片の厚みに応じた凹部を形成する必要があるが、凹部は従来の堀込みに比べて遥かに浅く形成されるので、各部材の強度を良好な状態に保持することができる。

[0012]
DETAILED DESCRIPTION OF THE INVENTION
As shown in FIG. 1, the first embodiment of the connecting structure of the wooden building members includes two main members 1, 1 made of orthogonal beams and girders, a joining member 2 made of fire-fire, and both main members 1, 1. 1 includes a connecting tool 3 for connecting the connecting member 2 obliquely to one corner portion, and fastening means 91 and 92 for fixing the connecting tool 3 to the main member 1 and the connecting member 2, respectively.
[0013]
The connection tool 3 is shown in FIGS. 1 to 4, and will be described with reference to FIG. 4 (A), and a rectangular connection piece 4 inclined to the right shoulder and a lower edge of the connection piece 4. It is a metal product composed of a cup-shaped protrusion 5 projecting downward from an intermediate portion. The means for integrating the connecting piece 4 and the protrusion 5 is performed by firmly welding the opposite portion of the end face of the peripheral wall of the protrusion 5 to the middle portion of the lower end of the connecting piece 4 in a pressed state. It has been broken. Since the fire staking is generally connected to a beam or girder at an angle of about 45 degrees, the connection piece 4 is inclined with respect to the protrusion 5 at an angle of about 45 degrees. Further, in the coupling tool 3, the protruding direction of the connecting piece 4 is the connecting direction of the bonding member 2. By using this, the both end portions of the joining member 2 can be fixed with the connector 3 having the same structure.
[0014]
The connecting piece 4 is a plate having a thickness of several millimeters, and is fixed to the joining member 2 by fastening means 92 including a bolt B, a nut N, and a locking pin P. Includes a U-shaped notch 41 for inserting the bolt B or nut N of the fastening means 91 for fixing the protrusion 5, and bolts are provided at opposite positions on both sides perpendicular to the side on which the protrusion 5 is provided. A U-shaped receiving hole 42 for hooking the shaft portion of B is provided in a state of opening to the outside, and two mounting holes 43 for inserting and supporting the locking pin P are opposed to the end of the upper side. We prepare for place to do.
[0015]
The protrusion 5 is fixed to the main member 1 by fastening means 91 including a bolt B and a nut N, and has a cup-shaped interior that opens upward as a storage portion 51 that houses the head of the bolt B or the nut N. The bottom wall is provided with a through hole 52 through which the shaft portion of the bolt B is inserted. The diameter of the storage portion 51 may be slightly larger than the diameter of the head of the bolt B or the nut N, or a tool that is fitted into the head of the bolt B or the nut N and tightens. You may form in the magnitude | size which can enter.
[0016]
As shown in FIG. 2, the main member 1 is provided with a disc-shaped fitting hole 11 for fitting the protrusion 5 in the center portion of the joining surface with which the end face of the joining member 2 abuts. In the bottom surface of the hole 11, a through hole 12 through which the shaft portion of the bolt B is inserted is provided at a position corresponding to the through hole 52 of the protrusion 5 so as to penetrate the opposite surface.
[0017]
The joining member 2 is formed with both end faces, which are joining faces abutting against the side surfaces of the main trunk member 1, inclined with respect to the longitudinal direction, and engaging grooves 21 into which the connecting pieces 4 are fitted are formed on each end face. It penetrates in the direction orthogonal to both longitudinal directions of the main trunk member 1 and the joining member 2, and is provided in a state where the longitudinal direction of the joining member 2 is the depth direction. Further, on the side surface of the joining member 2, the shaft portion of the bolt B is inserted into a portion corresponding to the inner portion of one of the two receiving holes 42 described above (the upper receiving hole 42 in FIG. 1). The through-hole 22 is provided in a state of penetrating the opposite surface through the engagement groove 21, and the through-hole 23 for driving and holding the locking pin P is provided at a position corresponding to the attachment hole 43. By the way, the engagement groove 21 is most preferably provided at a position where the two sides parallel to the longitudinal direction of the main trunk member 1 are divided into two equal parts. However, the engagement groove 21 may be provided at a slightly shifted position. There is no problem. The main member 1 and the joining member 2 are processed using a cutting tool such as a circular saw or a drill.
[0018]
The assembly procedure of the first embodiment described above will be described below. First, the protrusions 5 of the coupler 3 are respectively fitted in the fitting holes 11 of the main members 1 and adjusted so that the connection pieces 4 face the installation direction of the joining member 2. The shaft portion of the bolt B is inserted into the through hole 12 of the main trunk member 1 from the through hole 52 of the main shaft 1 and the nut 3 is tightened to fix the connector 3. Next, the bolts B of the fastening means 92 are respectively inserted into the through holes 22 provided at the ends of the joining member 2, and the nuts N are tightened. Subsequently, when the joining member 2 is lowered from above the connecting piece 4 and the connecting piece 4 is fitted into the engaging groove 21 of the joining member 2, the shaft portion of the bolt B fixed to the joining member 2 is connected to the connecting piece 2. 4, the connecting member 4 is supported by the connecting piece 4. Finally, the locking pin P is driven and fixed from the through hole 23 of the joining member 2 to the mounting hole 43 of the connection piece 4.
[0019]
The above assembling operation can be performed by one person because the shaft portion of the bolt B is caught in the receiving hole 42. Further, since the opening width of the receiving hole 42 is gradually increased as it approaches the tip, the shaft part of the bolt B fixed to the joining member 2 is pulled to the receiving hole 42 of the connecting piece 4. The work to hang is easy to do. Note that the locking pin P has the same appearance as the through-hole 23 or has a slightly shorter length so as not to protrude from the joining member 2.
[0020]

If described with reference to FIG. 6, the horizontal support piece 6 in which the connector 3 comes into contact with the joint surface of the main member 1 will be described. And a connecting piece 4 projecting downward from the left end of the support piece 6 and a protrusion 5 projecting upward from the support piece 6, and a recess for fitting the support piece 6 into the end surface of the joining member 2 24 is provided in a state communicating with the entrance portion of the engagement groove 21. The recess 24 is provided in a state of penetrating in a direction perpendicular to both longitudinal directions of the main trunk member 1 and the joining member 2, similarly to the engagement groove 21, using a cutting tool.
[0021]

Are connected to the left and right side surfaces of the central portion of the main member 1, and the ends of the two joining members 2 are fixed to one connector 3. It is a feature.
[0022]
The connecting tool 3 used for this is composed of two connection pieces 4 and 4 that are continuous in a V-shape, and a protrusion 5 that protrudes from a continuous portion of both connection pieces 4 and 4. Each joining member 2 has an end portion formed in a mountain shape with a perpendicular top, an engagement groove 21 is formed along the longitudinal direction from the top portion, and one surface of a set of inclined surfaces orthogonal to each other is the main member 1. The other surface is a surface that contacts the other bonding member 2. Further, a fitting hole 11 into which the projection body 5 is fitted is formed at the opposite location on both side surfaces of the main trunk member 1.
[0023]
As shown in FIG. 9, in the fourth embodiment of the connecting structure of the wooden building members , when a large connecting piece 4 is used, a plurality of protrusions 5 of the connecting tool 3 are provided and the locking pin P is held.

【The invention's effect】
If the connection tool of the wooden building member of Claim 2 is used, it can connect diagonally in the state which contact | abuts the end surface of a joining member to a main trunk member, and also comprises a connecting tool in a main trunk member and a joining member. It is only necessary to form a fitting hole or engagement groove according to the shape of the connecting piece to be projected and the protrusion, and the fitting hole and the engagement groove can be processed using a cutting tool. The processing applied to the member can be easily performed. Moreover, even if the fitting hole or the engagement groove is formed, the thickness of each member is the same as that before processing, so that the strength of each member is maintained in a good state that is not inferior to that before processing.
[0028]
If the connecting tool of the wooden building member according to claims 1 and 3 is used, the same effect as that when the connecting tool according to claim 2 is used is obtained, and the connecting tool is added to the connection piece and the protrusion. Therefore, it is necessary to form a recess according to the thickness of the support piece on the joining surface of the main member or the joining member. However, the recess is formed much shallower than the conventional excavation. Therefore, the strength of each member can be kept in a good state.
