Description

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。   The present invention is, for example, main members such as pillars, foundations, beams, girders, etc. It is related with the connection tool of the wooden building member for connecting these diagonally.

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。   As for the connection structure of the above-mentioned types of wooden building members, a structure in which an end portion of a joining member is fitted into a pit formed in a main trunk member and connected by bolts, nuts, or a brace is conventionally known. However, the excavation processing is a troublesome operation that requires high technology, and there is a current situation where skilled craftsmen are lacking. Therefore, an easy-to-process connection structure is desired in the construction industry. In addition, when the digging is formed, the thickness of the part becomes much thinner than other parts and the strength of the wood is greatly reduced, so that sufficient strength cannot be obtained unless thick wood is used Met.

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。   The present invention has been made in view of the above circumstances, and the object of the present invention is to easily perform the processing applied to the connecting portion of the wood and to maintain the strength of the wood in a good state after the processing. It is to provide a connecting tool for a wooden building member.

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、接続片の端部から主幹部材の接合面に設けた嵌合穴に嵌まり込む状態で突設する突起体と、から構成し、突起体はカップ形状であって、カップ形状の内部を主幹部材用の締結手段のボルトの頭部若しくはナットを収める収納部とし、嵌合穴の底面の抜孔にボルトの軸部を挿通する通孔を、カップ形状の底部に備えていることを特徴とする。   In order to achieve the above-mentioned object, the invention according to claim 1 of the present invention is characterized in that the fastening means is accommodated in both the main member and the main member so as to be obliquely connected with the end face of the joining member being in contact. A connecting piece of a wooden building member fixed by a connecting piece that fits into an engaging groove provided on the joining surface of the joining member, and a fitting hole provided on the joining surface of the main member from the end of the connecting piece A projection that projects in a state of being fitted into the cup, and the projection is cup-shaped, and the inside of the cup is used as a storage portion for accommodating the head of the bolt or nut of the fastening means for the main member, The cup-shaped bottom part is provided with a through-hole through which the shaft part of the bolt is inserted into the hole on the bottom surface of the fitting hole.

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。   The main member is composed of pillars, foundations, beams, girders and the like. The joining member is made of firewood, bracing, bracing, jointing, or a heddle material attached to a corner member provided at a protruding corner, an entering corner, or the like. The fastening means includes at least a bolt and a nut. The connection piece is stored in the engagement groove slightly wider than the connection piece without rattling. The protrusion is stored in a fitting hole slightly larger than the diameter of the protrusion without rattling.

また、請求項２記載の発明は、接続片は長方形状であって、突起体を設けた辺の端部には、主幹部材用の締結手段のボルト若しくはナットを挿入するＵ字型の切欠部を備え、突起体を設けた辺に直交する両辺の対向箇所には、係合溝を経て両側面に貫通する透孔に挿通する接合部材用の締結手段のボルトの軸部を引っ掛けるＵ字型の受孔を外部に開口する状態で設けると共に、突起体を設けた辺とは対向する辺の端部には、係合溝を経て両側面に貫通する貫通孔に打ち込む接合部材用の締結手段の係止ピンを挿通して支持する取付孔を、対向する箇所に備えていることを特徴とする。   In the invention according to claim 2, the connection piece has a rectangular shape, and a U-shaped cutout portion into which a bolt or nut of a fastening means for the main member is inserted at the end of the side provided with the protrusion. A U-shaped hook that hooks a shaft portion of a bolt of a fastening member for a joining member that is inserted into a through-hole penetrating to both side surfaces through an engaging groove at opposite positions on both sides orthogonal to the side on which the protrusion is provided. The fastening means for the joining member is provided in a state where the receiving hole is opened to the outside, and is driven into the through hole penetrating the both side surfaces through the engaging groove at the end of the side opposite to the side provided with the protrusion. A mounting hole for inserting and supporting the locking pin is provided at an opposite position.

請求項１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。   If the connection tool of the wooden building member of Claim 1 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.

請求項２記載の木造建築部材の連結具は、突起体を締結手段のボルト、ナットによって主幹部材に締結し、接合部材の係合溝に接続片を嵌め込むようにすると、接合部材に止めた別の締結手段のボルトの軸部が接続片の受孔に引っ掛かるし、接合部材の貫通孔から係止ピンを打ち込むだけで接続片の取付孔に固定できるので、組立作業を容易に行える。また、連結具を１８０度回転させれば、接続片が右肩上がりに傾斜する状態から左肩上がりに傾斜する状態になり、連結具を有効活用できる。   When the projection is fastened to the main member by the bolts and nuts of the fastening means and the connecting piece is fitted in the engaging groove of the joining member, the connecting member of the wooden building member according to claim 2 is stopped by the joining member. Since the shaft portion of the bolt of another fastening means is caught in the receiving hole of the connecting piece, and can be fixed to the mounting hole of the connecting piece simply by driving the locking pin from the through hole of the joining member, the assembling work can be easily performed. Further, if the connecting tool is rotated 180 degrees, the connecting piece changes from a state in which the connecting piece is inclined to the right shoulder to a state in which the connecting piece is inclined to the left shoulder, and the connecting tool can be effectively used.

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。   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.

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。   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.

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。   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.

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。   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.

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。   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.

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。   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.

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。   The assembly procedure of the first embodiment described above will be described below. First, after fitting the projections 5 of the coupler 3 into the fitting holes 11 of the main members 1 and adjusting the connection pieces 4 so as to face the installation direction of the joining member 2, the projections are used using the fastening means 91. The shaft portion of the bolt B is inserted into the hole 12 of the main trunk member 1 from the through hole 52 of the main shaft 1, and the nut N 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 each end 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 connection 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.

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。   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.

木造建築部材の連結構造の第二実施形態は図５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６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。   As shown in FIG. 5, in the second 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. A large number of attachment holes 43 are provided. In this case, the main member 1 is provided with the fitting holes 11 according to the number of the protrusions 5, and the joining member 2 is provided with the through holes 23 according to the number of the attachment holes 43. The protrusion 5 may have a cup shape having a circular bottom portion, or may have a cup shape having a square bottom portion. As shown in FIG. 6, the connection piece 4 and the protrusion 5 are originally separate and are integrated by welding, but in order to firmly weld the protrusion 5 to the connection piece 4. The portion of the projection 5 facing the peripheral wall is cut into a V-shape and welded with the cut-out portion pressed against the peripheral edge of the cut-out portion 41 of the connection piece 4 to widen the welding area and reinforce. It is. In this case, it is necessary to cut the entrance side portion of the engagement groove 21 formed on the joining surface of the joining member 2 in order to fit the reinforcing portion of the peripheral wall of the protrusion 5.

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。   The connection structure of the wooden building members is not limited to the above embodiment. For example, when the connecting piece 3 composed of one connecting piece 4 and the protrusion 5 is arranged so that the connecting piece 4 faces the installation direction of the joining member 2 in FIG. The abutting side has a structure in which the side is in an upright state. However, the structure is not limited to this structure, and when the connection piece 4 is directed in the installation direction of the joining member 2, the contact piece 4 contacts the main member 1. The contact side may be a tilted structure or a horizontal structure. In this case, the engagement groove 21 of the joining member 2 into which the connecting piece 4 is fitted is formed by the main member 1 and the joining member 2. Instead of being provided in a state of penetrating in a direction orthogonal to the two longitudinal directions, it may be provided in a state of penetrating according to the inclination of the connecting piece 4 of the connector 3. In addition, the connecting tool 3 composed of the single connection piece 4 and the protrusion 5 is formed so that the protruding direction of the connection piece 4 completely coincides with the installation direction of the joining member 2. In this case, the depth direction of the engaging groove 21 of the joining member 2 is not parallel to the longitudinal direction of the joining member 2 but may be provided according to the protruding direction of the connecting piece 4. .

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。   Furthermore, a nut N may be welded in advance and integrally provided in the storage portion 51 formed on the protrusion 5 of the connector 3. In addition, the connecting tool 3 projects the protrusion 5 obliquely with respect to the connection piece 4 at an angle of about 45 degrees, but is not necessarily limited to this projecting angle, and the main member 1 and the joining member. There is no problem changing the angle according to the connection angle of 2. In addition, the connection piece 4 may have a structure that does not have the receiving hole 42.
