Description

接合金物及び建物構造Bonded hardware and building structure
　本発明は、支持材に横架材を接合する際に用いる接合金物及び該接合金物を用いて支持材と横架材を接合した建物構造に関する。 The present invention relates to a joint metal used when a horizontal member is joined to a support member, and a building structure in which the support member and the horizontal member are joined using the joint member.
　従来から、木造建築物において、柱等の木材と梁等の木材を接合する方法としては、施工の効率化や接合部の耐力確保等の目的から様々な形状の接合金物が利用されている。 Conventionally, as a method of joining wood such as a pillar and wood such as a beam in a wooden building, joining hardware of various shapes has been used for the purpose of improving the efficiency of construction and ensuring the strength of the joint.
　このような接合金物としては、例えば、柱の側面に接触した状態で固定される前面板と、該前面板の両端が折り曲げられて梁側に突出した一対の側面板とによりコの字状に構成されるものがある（例えば、特許文献１参照）。この接合金物では、前面板にボルトを挿通するための前孔が上下に並んで複数形成されている。前面板は、これらの前孔に挿通されたボルトが柱を貫通した状態でナットによって締結されることにより、柱の側面に固定される。また、側面板は、上下に並んで複数のピン孔が形成されており、梁の端面に形成された溝に挿入された状態で、梁の側面に形成された横孔からドリフトピンが打ち込まれることにより、梁に連結される。 As such a joint metal fitting, for example, a front plate fixed in contact with the side surface of the column and a pair of side plates bent at both ends of the front plate and projecting to the beam side are formed into a U shape. Some are configured (see, for example, Patent Document 1). In this metal joint, a plurality of front holes for inserting bolts through the front plate are formed side by side. The front plate is fixed to the side surface of the column by fastening the bolt inserted through these front holes with a nut in a state of passing through the column. The side plate is formed with a plurality of pin holes arranged vertically, and a drift pin is driven from a lateral hole formed on the side surface of the beam while being inserted into a groove formed on the end surface of the beam. As a result, it is connected to the beam.
　しかしながら、このような接合金物では、接合部に過大な荷重が作用した場合に、当該金物が変形する前に、梁にひび割れが生じ、最終的には梁が割裂して接合部が破壊される。また、木材は、含水率等の要因で強度に個体差があるため、このような接合金物を用いた場合には、木材の割裂が降伏点の決定要因となり、降伏耐力等のバラつきが大きくなる。そこで、側面板に形成されたピン孔以外の領域で上下左右に広く開口した欠損部を複数形成することにより、梁に過大な荷重が作用した際に、側面板が塑性変形し、この塑性変形でエネルギーを吸収することで、梁に作用する局所的な負荷を軽減して、梁のひび割れの発生を遅くする接合金物が開示されている（例えば、特許文献２参照）。 However, in such a joint hardware, when an excessive load is applied to the joint, the beam is cracked before the hardware is deformed, and eventually the beam is split and the joint is destroyed. . In addition, because wood has individual differences in strength due to factors such as moisture content, when using such a joint hardware, the splitting of wood becomes a determinant of the yield point, resulting in large variations in yield strength, etc. . Therefore, by forming multiple notches that open widely in the top, bottom, left, and right in areas other than the pin holes formed in the side plate, the side plate plastically deforms when an excessive load is applied to the beam, and this plastic deformation The joint hardware which reduces the local load which acts on a beam and absorbs energy by delaying the generation | occurrence | production of the crack of a beam is disclosed (for example, refer patent document 2).

　しかしながら、特許文献２の接合金物では、側面板に形成されている欠損部の領域が側面板の大部分を占めているため、金物全体の剛性が低くなり、接合部に荷重が作用した際に、必要以上に早い段階で塑性変形が生じる。そのため、降伏耐力の値が低くなるので、梁の破壊挙動のバラつきは小さくなるものの、接合部全体として必ずしも高い強度性能が得られるというものではなかった。また、図２７に示すように、従来のコの字状に形成される接合金物１００では、ボルトを挿通するための前孔が形成されている前面板４を高トルクでボルト６を締め付けて柱２等の側面に固定した場合に、図２７（ａ）に示すように、前面板４がボルト６側（矢印方向）に引き寄せられ、図２７（ｂ）に示すように、一対の側面板５が内側又は外側へと倒れることがあり、梁の端面に形成された溝と干渉してしまうという問題がある。 However, in the joint hardware of Patent Document 2, since the region of the missing portion formed on the side plate occupies most of the side plate, the rigidity of the entire hardware is reduced, and a load acts on the joint. Plastic deformation occurs at an earlier stage than necessary. For this reason, since the yield strength value is lowered, the variation in the fracture behavior of the beam is reduced, but high strength performance is not necessarily obtained as a whole joint. Further, as shown in FIG. 27, in a conventional metal fitting 100 formed in a U-shape, a front plate 4 in which a front hole for inserting a bolt is formed is fastened with a bolt 6 with a high torque to a column. When fixed to the side surface such as 2, the front plate 4 is drawn toward the bolt 6 (arrow direction) as shown in FIG. 27 (a), and the pair of side plates 5 as shown in FIG. 27 (b). May fall inward or outward and interfere with the grooves formed in the end face of the beam.
　本発明は、上記のような課題に鑑みてなされたものであって、柱等の支持材と梁等の横架材の接合部に過大な荷重が作用した際に、接合部の降伏耐力、初期剛性、エネルギー吸収力等が損なわれず、且つ接合部としての強度の安定性に優れた信頼性の高い接合金物及び建物構造を提供することを目的とする。また、支持材の側面に固定される固定板がボルトで締め付けられた際に、固定板から横架材側に突出して設けられる連結板が倒れるのを抑制することができる接合金物及び建物構造を提供することを目的とする。 The present invention has been made in view of the problems as described above, and when an excessive load is applied to a joint between a support member such as a column and a horizontal member such as a beam, the yield strength of the joint portion, An object of the present invention is to provide a highly reliable joint metal fitting and building structure in which initial rigidity, energy absorption ability, and the like are not impaired and the strength stability as a joint portion is excellent.

Further, a bolt hole 21 and a counterbore hole 22 are formed on the side surface of the support member 2. The bolt hole 21 is for inserting a bolt 6 for fixing the fixing plate 4. The counterbore hole 22 is for accommodating the nut 7 screwed into the bolt 6 inserted into the bolt hole 21. When fixing the fixing plate 4 to the side surface of the support member 2, in a state where the back surface portion 42 of the fixing plate 4 is in contact with the side surface of the support member 2 so that the fixing hole 41 and the bolt hole 21 coincide with each other, The bolt 6 is inserted from the fixing hole 41. The fixing plate 4 is fixed to the side surface of the support member 2 by screwing the nut 7 with the bolt 6 inserted until the tip of the bolt 6 reaches the counterbore hole 22. The fixing method of the fixing plate 41 is not limited to this, and may be fixed by driving a nail or the like into the side surface of the support member 2 from the fixing hole 41 instead of the bolt 6.
　連結板５は、横架材３に連結されるものであって、図１及び図２に示すように、固定板４の両端から略直角に折り曲げられて、横架材３側へ突出するように延びている。この連結板５は、略Ｕ字状に切り欠かれたピン溝５１と、該ピン溝５１の下方側の周囲を切り欠いて形成された第６欠損部５３１と、横架材３に連結されるためのドリフトピン８が挿通される複数の連結孔５２と、該連結孔５２の周囲を切り欠いて形成された複数の第２欠損部５３２、５３３とを有している。 The connecting plate 5 is connected to the horizontal member 3, and is bent at substantially right angles from both ends of the fixed plate 4 so as to protrude toward the horizontal member 3 as shown in FIGS.

A plurality of connecting holes 52 through which the drift pins 8 are inserted, and a plurality of second defect portions 532 and 533 formed by cutting out the periphery of the connecting holes 52.
　ピン溝５１は、ドリフトピン８を受けることができるように、連結板５の上端に形成されている。連結孔５２は、ピン溝５１の下方で鉛直方向に並んで複数形成されており、このピン溝５１及び複数の連結孔５２が並ぶ鉛直方向の直線Ａ上を通るように鉛直方向に長尺なスリット状の第６欠損部５３１及び複数の第２欠損部５３２、５３３が形成されている。また、横架材３の端面には、一対の連結板５をそれぞれ挿入するための溝３１が縦方向（鉛直方向）に渡って形成されおり、側面にはドリフトピン８を打ち込むためのピン孔３２が縦方向に並んで複数形成されている。この横架材３と連結板５とを連結させる際は、まず支持材２の側面に固定板４が固定された接合金物１の上方に位置するよう横架材３を移動させる。この際、横架材３の一番上に位置するピン孔３２には、予めドリフトピン８を打ち込んでおく。そして、横架材３を打ち込み済みのドリフトピン８がピン溝５１に当接するまで徐々に下降させて、一対の連結板５が横架材３の溝３１に挿入された状態で、残りのピン孔３２にドリフトピン８を打ち込むことにより横架材３と連結板５とが連結される。 The pin groove 51 is formed at the upper end of the connecting plate 5 so as to receive the drift pin 8. A plurality of connection holes 52 are formed in the vertical direction below the pin grooves 51, and are elongated in the vertical direction so as to pass on the straight line A in the vertical direction in which the pin grooves 51 and the plurality of connection holes 52 are arranged. A slit-like sixth defect portion 531 and a plurality of second defect portions 532 and 533 are formed. Further, grooves 31 for inserting the pair of connecting plates 5 are formed in the end surface of the horizontal member 3 in the vertical direction (vertical direction), and pin holes for driving the drift pins 8 on the side surfaces. A plurality of 32 are formed side by side in the vertical direction. When connecting the horizontal member 3 and the connecting plate 5, first, the horizontal member 3 is moved so as to be positioned above the joint hardware 1 in which the fixing plate 4 is fixed to the side surface of the support member 2. At this time, the drift pin 8 is driven in advance into the pin hole 32 positioned at the top of the horizontal member 3. Then, the horizontal member 3 is gradually lowered until the drift pin 8 that has been driven is in contact with the pin groove 51, and the remaining pins are inserted with the pair of connecting plates 5 inserted into the grooves 31 of the horizontal member 3. The horizontal member 3 and the connecting plate 5 are connected by driving the drift pin 8 into the hole 32.
　連結板５に形成される第６欠損部５３１及び第２欠損部５３２、５３３は、連結板５と横架材３が連結された状態で、支持材２と横架材３の接合部に過大な荷重が作用した際に、ピン溝５１及び連結孔５２の周囲を変形し易くすることにより、横架材の割裂を抑制させるためのものである。図１に示すように、第６欠損部５３１は、ピン溝５１と当該ピン溝５１と鉛直方向に隣接して形成される第２欠損部５３２との間に鉛直方向へ長尺に形成されている。また、第２欠損部５３２は、鉛直方向に隣接する連結孔５２の間に位置するように、それぞれの連結孔５２から所定間隔離れた位置に形成されている。この第２欠損部５３２は、それぞれの連結孔５２の中心を通る鉛直方向の直線Ａ上に沿って長尺に形成されている。また、第２欠損部５３２は、図１に示すように、その幅は連結孔５１の直径Φより狭く形成されており、固定板４から所定距離Ｗ離れた位置に設けられている。 The sixth defect portion 531 and the second defect portions 532 and 533 formed on the connecting plate 5 are excessively large at the joint between the support member 2 and the horizontal member 3 in a state where the connecting plate 5 and the horizontal member 3 are connected. This is intended to suppress the splitting of the horizontal member by facilitating deformation of the periphery of the pin groove 51 and the connecting hole 52 when a heavy load is applied. As shown in FIG. 1, the sixth defect portion 531 is elongated in the vertical direction between the pin groove 51 and the second defect portion 532 formed adjacent to the pin groove 51 in the vertical direction. Yes. Moreover, the 2nd defect | deletion part 532 is formed in the position away from each connection hole 52 by predetermined spacing so that it may be located between the connection holes 52 adjacent in the perpendicular direction. The second defect portion 532 is formed to be long along a vertical straight line A passing through the center of each connecting hole 52. Further, as shown in FIG. 1, the second defect portion 532 has a width narrower than the diameter Φ of the connection hole 51 and is provided at a position away from the fixed plate 4 by a predetermined distance W.
　この所定距離Ｗは、図１（ｂ）に示すように、連結板５の基端から第６欠損部５３１及び第２欠損部５３２、５３３の基端側までの距離のことである。また、この距離Ｗは、連結孔５２の位置等に応じて変わるものであるが、連結孔５２、第６欠損部５３１、及び第２欠損部５３２、５３３は、それぞれ連結板５の水平方向の幅Ｗ１の中央よりも先端側に設けられることが好ましい。これにより、連結孔５２の周囲以外の領域の剛性をより向上させることができる。尚、連結板５の固定板４側を基端側とし、連結板５の開放側を先端側としている。また、第６欠損部５３１、第２欠損部５３２、５３３の縦方向の長さは、ピン溝５１の位置や連結孔５２の縦方向の間隔に応じて変わるものであり、本実施形態に係る接合金物１では、ピン溝５１と一番上に位置する連結孔５２の間に設けられる第６欠損部５３１の長さＬ１と一番下に位置する連結孔５２の下側に設けられる第２欠損部５３３は、連結孔５２の間に設けられる第２欠損部５３２より短く形成されている。 The predetermined distance W is a distance from the proximal end of the connecting plate 5 to the proximal end sides of the sixth defect portion 531 and the second defect portions 532 and 533, as shown in FIG. The distance W varies depending on the position of the connection hole 52 and the like. The connection hole 52, the sixth defect portion 531, and the second defect portions 532 and 533 are each in the horizontal direction of the connection plate 5. It is preferable to be provided on the tip side from the center of the width W1. Thereby, the rigidity of the region other than the periphery of the connection hole 52 can be further improved. The fixed plate 4 side of the connecting plate 5 is the base end side, and the open side of the connecting plate 5 is the leading end side. In addition, the longitudinal lengths of the sixth defect portion 531 and the second defect portions 532 and 533 vary depending on the position of the pin groove 51 and the distance between the connection holes 52 in the longitudinal direction. In the metal joint 1, the length L1 of the sixth defect portion 531 provided between the pin groove 51 and the uppermost connecting hole 52 and the second lower portion provided below the lowermost connecting hole 52. The defect part 533 is formed shorter than the second defect part 532 provided between the connection holes 52.
　次に、本発明の第２の実施形態に係る接合金物１ａについて、図３及び図４を参照しつつ説明する。この接合金物１ａは、主に第１の実施形態に係る接合金物１の第６欠損部５３１及び第２欠損部５３２、５３３の形状を変更したものであり、接合金物１と同様の構成等については、同一の符号を付し、その詳細な説明については省略する。 Next, a metal joint 1a according to a second embodiment of the present invention will be described with reference to FIGS. This metal joint 1a is obtained by changing the shapes of the sixth defect portion 531 and the second defect portions 532 and 533 of the metal joint 1 according to the first embodiment. Are denoted by the same reference numerals, and detailed description thereof will be omitted.
　接合金物１ａは、連結孔５２の周囲に該連結孔５２を中心とする同径の円弧状の長穴である第１欠損部５４を周方向に等間隔で３個形成し、ピン溝５１の下方側の周囲にも円弧状の第５欠損部５５を２個形成したものである。第１欠損部５４及び第５欠損部５５の周方向に直交する幅は、連結孔５２の直径の半分以下に形成されている。また、円弧の長さは第１欠損部５４の方が、第５欠損部５５より長く形成されている。このように、接合金物１ａでは、連結孔５２及びピン溝５１の周囲のみに第１欠損部５４及び第５欠損部５５を設けているので、連結板５ａと横架材３が連結された状態で、支持材２と横架材３の接合部に過大な荷重が作用した際に、連結孔５２及びピン溝５１の周囲を効率良く変形させることができ、横架材３の割裂を抑制することができる。 The metal joint 1 a is formed with three first deficient portions 54 that are arc-shaped elongated holes having the same diameter around the connection hole 52 around the connection hole 52 at equal intervals in the circumferential direction. Two arc-shaped fifth defect portions 55 are also formed around the lower side. The width perpendicular to the circumferential direction of the first defect portion 54 and the fifth defect portion 55 is formed to be half or less of the diameter of the connection hole 52. Further, the length of the arc is such that the first defect portion 54 is longer than the fifth defect portion 55. In this way, in the metal joint 1a, since the first defect portion 54 and the fifth defect portion 55 are provided only around the connection hole 52 and the pin groove 51, the connection plate 5a and the horizontal member 3 are connected. Thus, when an excessive load is applied to the joint between the support member 2 and the horizontal member 3, the periphery of the connection hole 52 and the pin groove 51 can be efficiently deformed, and the split of the horizontal member 3 is suppressed. be able to.
　また、周方向に隣り合う第１欠損部５４は、図４に斜線を引いて示すように、それぞれ結合部５６によって結ばれている。この結合部５６は、隣り合う第１欠損部５４の端部の間に位置する部分であり、図３及び図４に示すように、第１欠損部５４が３個形成される場合には、連結孔５２の周囲に３箇所設けられることになる。また、接合金物１ａでは、結合部５６のうちの１つは、連結孔５２の中心を通って水平方向に延びる仮想線Ｂ上で、且つ連結孔５２より連結板５ａの先端側に位置するように設けられている。これにより、この連結板５ａと横架材３が連結された状態で、横架材３に対して連結板５ａの水平方向側へ作用する引張り荷重に対する耐力を向上させることができる。また、第１欠損部５４は、直線Ｂに対して線対称に形成されているので、横架材３に対して鉛直方向の上下いずれの向きに過大な荷重が作用する際にも、効率良く連結孔の周囲が変形して横架材３の割裂を抑制することができる。尚、この第１欠損部５４も第２欠損部５３２と同様に、所定の剛性を保つために連結板５ａの水平方向の幅の中央よりも先端側に設けられていることが好ましい。 Further, the first defect portions 54 adjacent in the circumferential direction are connected by the connecting portions 56 as shown by hatching in FIG. The coupling portion 56 is a portion located between the end portions of the adjacent first defect portions 54. As shown in FIGS. 3 and 4, when three first defect portions 54 are formed, Three places are provided around the connection hole 52. Further, in the joint hardware 1 a, one of the coupling portions 56 is located on the imaginary line B that extends in the horizontal direction through the center of the coupling hole 52, and on the distal end side of the coupling plate 5 a from the coupling hole 52. Is provided. Thereby, in the state which this connection plate 5a and the horizontal member 3 were connected, the yield strength with respect to the tensile load which acts on the horizontal direction side of the connection plate 5a with respect to the horizontal member 3 can be improved. Moreover, since the 1st defect | deletion part 54 is axisymmetrically formed with respect to the straight line B, even when an excessive load acts on the horizontal member 3 in any of the vertical direction, it is efficient. The periphery of the connecting hole can be deformed to prevent the horizontal member 3 from being split. In addition, like the 2nd defect | deletion part 532, it is preferable that this 1st defect | deletion part 54 is provided in the front end side rather than the center of the horizontal width | variety of the connection plate 5a in order to maintain predetermined rigidity.
　図５に示す接合金物１ａは、連結孔５２の周囲に２個の円弧状の第１欠損部５４ａを形成したものである。この第１欠損部５４ａは、図３に示す第１欠損部５４と幅は同一であるが、円弧の長さが長く形成されている。この第１欠損部５４ａも第１欠損部５４と同様に周方向に隣り合う第１欠損部５４ａは、それぞれ結合部５６によって結ばれており、結合部５６のうちの１つは、連結孔５２の中心を通って水平方向に延びる仮想線Ｂ上で、且つ連結孔５２より連結板５ａの先端側に位置するように設けられている。 5 is formed by forming two arc-shaped first defect portions 54a around the connection hole 52. As shown in FIG. The first defect 54a has the same width as the first defect 54 shown in FIG. 3, but has a long arc. Similarly to the first defect part 54, the first defect part 54 a adjacent in the circumferential direction is connected by the coupling part 56, and one of the coupling parts 56 is connected to the connection hole 52. It is provided so that it may be located on the front end side of the connection board 5a on the imaginary line B which extends in the horizontal direction through the center of the connection hole 52.
　図６に示す接合金物１ａの第１欠損部５４ｂは、図４に示す第１欠損部５４よりも周方向に直交する幅を約２倍近く広めに形成したものである。この第１欠損部５４ａのように、連結孔５２の周囲で欠損領域を広くすることで、連結板５ａと横架材３が連結された状態で、横架材３に過大な荷重が作用した際に、連結孔５２の周囲をより効率良く変形させることができる。また、図７に示す接合金物１ａの第１欠損部５４ｃは、図５に示す第１欠損部５４ｂと同一の幅で、円弧の長さを長く形成したものである。 The first chipped portion 54b of the metal joint 1a shown in FIG. 6 is formed to have a width that is approximately twice as wide as that of the first chipped portion 54 shown in FIG. Like the first defect 54a, an excessive load is applied to the horizontal member 3 in a state where the connection plate 5a and the horizontal member 3 are connected by widening the defect region around the connection hole 52. In this case, the periphery of the connection hole 52 can be deformed more efficiently. Moreover, the 1st defect | deletion part 54c of the metal joint 1a shown in FIG. 7 is the same width | variety as the 1st defect | deletion part 54b shown in FIG. 5, and forms the length of the circular arc long.

The metal joint 1b is formed by forming a third defect portion 57 and a fourth defect portion 58 having different shapes on the connecting plate 5b. The same reference numerals are given to the same components as the metal joints 1 and 1a. Detailed description thereof will be omitted.
　接合金物１ｂの連結板５ｂは、図８に示すように、図３に示す接合金物１ａの連結板５ａに形成されている円弧状の第１欠損部５４と同様の形状の第３欠損部５７と、図１及び図２に示す接合金物１の連結板５に形成されている鉛直方向に長尺なスリット状の第２欠損部５３２、５３３とそれぞれ同様の形状の第４欠損部５８１、５８２とを有するものである。この第３欠損部５７及び第４欠損部５８は、図８に示すように、求められる耐力等に応じて、それぞれ連結孔５２の周囲及び鉛直方向に隣接する連結孔５２の間に形成されていれば良い。 As shown in FIG. 8, the connecting plate 5b of the metal joint 1b has a third defective portion 57 having the same shape as the arc-shaped first defective portion 54 formed on the connecting plate 5a of the metal joint 1a shown in FIG. And fourth defect portions 581 and 582 having the same shape as the slit-shaped second defect portions 532 and 533 formed in the connecting plate 5 of the metal joint 1 shown in FIGS. It has. As shown in FIG. 8, the third defect portion 57 and the fourth defect portion 58 are formed around the connection hole 52 and between the connection holes 52 adjacent in the vertical direction, respectively, according to the required yield strength and the like. Just do it.
　次に、本発明の第４の実施形態に係る接合金物１ｃについて、図９を参照しつつ説明する。この接合金物１ｃは、連結孔５２と連なるようにして横長のスリット状の第７欠損部５９を形成したものであり、接合金物１と同様の構成等については、同一の符号を付し、その詳細な説明については省略する。 Next, a metal joint 1c according to a fourth embodiment of the present invention will be described with reference to FIG. This metal joint 1c is formed by forming a horizontally elongated slit-like seventh defect portion 59 so as to be continuous with the connecting hole 52. The same reference numerals are given to the same components as the metal joint 1 and the like. Detailed description is omitted.
　接合金物１ｃの連結板５ｃは、連結孔５２に連なって切り欠かれた第７欠損部５９を有している。この第７欠損部５９は、連結孔５２を通る水平方向の直線Ｃ上に沿って長尺に形成されている。また、この第７欠損部５９の鉛直方向の幅は、連結孔５２の直径より小さく形成されており、連結孔５２から連結板５ｃの基端側及び先端側の両側に向かってそれぞれ形成されている。基端側へと長尺に延びて形成されている第７欠損部５９ａの長さＷ３は、先端側に延びて形成されている第７欠損部５９ｂの長さＷ４より長尺に形成されている。このような第７欠損部５９が連結板５ｃに形成される接合金物１ｃでは、連結板５ｃと横架材３が連結された状態で、支持材２と横架材３の接合部に過大な荷重が作用した際に、連結孔５２の周囲を効率良く変形させることができるので、横架材３の割裂を抑制することができる。また、連結孔５２の周囲以外の領域の剛性を向上させることができる。尚、本実施形態では、ピン溝５１の下方側の周囲には、欠損部が形成されていないが、図１に示すような縦長のスリット状の第６欠損部５３１や図３に示すような円弧状の第５欠損部５５を形成するようにしても良い。 The connecting plate 5 c of the metal joint 1 c has a seventh deficient portion 59 that is cut out continuously to the connecting hole 52. The seventh defect portion 59 is formed in a long shape along a horizontal straight line C passing through the connection hole 52. Further, the width of the seventh defect portion 59 in the vertical direction is smaller than the diameter of the connection hole 52 and is formed from the connection hole 52 toward both the proximal end side and the distal end side of the connection plate 5c. Yes. The length W3 of the seventh defect portion 59a formed to extend to the base end side is longer than the length W4 of the seventh defect portion 59b formed to extend to the distal end side. Yes. In the metal joint 1c in which such a seventh deficient portion 59 is formed in the connecting plate 5c, the connecting plate 5c and the horizontal member 3 are connected to each other, and the connecting portion between the support member 2 and the horizontal member 3 is excessive. Since the periphery of the connecting hole 52 can be efficiently deformed when a load is applied, the splitting of the horizontal member 3 can be suppressed. Further, the rigidity of the region other than the periphery of the connection hole 52 can be improved. In the present embodiment, no missing portion is formed around the lower side of the pin groove 51, but a vertically long slit-like sixth missing portion 531 as shown in FIG. 1 or as shown in FIG. An arcuate fifth defect 55 may be formed.

　表１に示すように、実施例１～３を比較例１と比べた場合、降伏耐力Ｐｙにおいて、その平均値は実施例１～３のいずれも比較例１に対して遜色ない値を保ちつつ、ばらつき係数が大幅に改善されていることから、耐力評価値は明らかに向上している。また、２／３Ｐｍａｘにおいても、その平均値は実施例１～３のいずれも比較例１に対して遜色ない値を保ちつつ、ばらつき係数が大幅に改善されていることから、耐力評価値は明らかに向上している。初期剛性及びエネルギーにおいては、その平均値は実施例１～３のいずれも比較例１に対して目立った低下はなかった。 As shown in Table 1, when Examples 1 to 3 were compared with Comparative Example 1, the average yield value of the yield strength Py was maintained in comparison with Comparative Example 1 in all of Examples 1 to 3. Since the variation coefficient is greatly improved, the proof stress evaluation value is clearly improved. In addition, the average value of 2 / 3Pmax is clearly the same as that of Examples 1 to 3 while maintaining the same value as that of Comparative Example 1 and the variation coefficient is greatly improved. Has improved. In the initial stiffness and energy, the average values of Examples 1 to 3 did not significantly decrease compared to Comparative Example 1.

In addition, the average value of 2 / 3Pmax was not lowered in any of Examples 1 to 3 as in Comparative Example 2, and the variation coefficient was improved over that of Comparative Example 2. The value is clearly improving.

　本実施形態では、１対の連結板５～５ｃを備える上面視コの字状の接合金物１～１ｃを用いて説明してきたが、必ずしも１対の連結板５～５ｃに限定されるものではなく、連結板５～５ｃが１枚だけの上面視Ｔ字状の接合金物に適用することも可能である。 In the present embodiment, the description has been made using the U-shaped joining hardware 1 to 1c provided with the pair of connecting plates 5 to 5c, but the present invention is not necessarily limited to the pair of connecting plates 5 to 5c. In addition, the present invention can be applied to a T-shaped joining hardware with only one connecting plate 5 to 5c.
　以下、固定板４がボルト等の固定具で締め付けられた際に、連結板５が図２７に示すように、倒れてしまうのを抑制するための補強を施した実施形態について図１６～図２６を参照しつつ説明する。尚、接合金物１と同様の構成等については、同一の符号を付し、その詳細な説明については省略する。 In the following, with respect to an embodiment in which reinforcement is performed to prevent the connecting plate 5 from falling down as shown in FIG. 27 when the fixing plate 4 is tightened with a fixture such as a bolt. Will be described with reference to FIG. In addition, about the structure similar to the joining metal fitting 1, the same code | symbol is attached | subjected and the detailed description is abbreviate | omitted.
　本発明の第５の実施形態に係る接合金物１ｄは、図１６～図１８に示すように、固定板４の両端から略直角に折り曲げられて、略水平に突出した一対の連結板５が設けられるものであり、上面視コの字状に構成されている。接合金物１ｄは、第１の実施形態に係る接合金物１と同様に、固定板４には、ボルト等の固定具（不図示）を挿通するための固定孔４１が縦方向に複数並んで形成されており、連結板５には、略Ｕ字状に切り欠かれたピン溝５１と、該ピン溝５１の下方で鉛直方向に並んで設けられる連結孔５２と、このピン溝５１及び複数の連結孔５２が並ぶ鉛直方向の直線Ａ上を通るように鉛直方向に長尺なスリット状の第６欠損部５３１及び複数の第２欠損部５３２、５３３とが形成されている。 As shown in FIGS. 16 to 18, the metal joint 1d according to the fifth embodiment of the present invention is provided with a pair of connecting plates 5 which are bent substantially at right angles from both ends of the fixing plate 4 and project substantially horizontally. It is configured in a U shape when viewed from above. Similar to the metal joint 1 according to the first embodiment, the metal joint 1d is formed with a plurality of fixing holes 41 arranged in the vertical direction in the fixing plate 4 for inserting a fixture (not shown) such as a bolt. The connecting plate 5 has a pin groove 51 cut out in a substantially U-shape, a connecting hole 52 provided in the vertical direction below the pin groove 51, and the pin groove 51 and the plurality of pin grooves 51. A slit-like sixth defect portion 531 and a plurality of second defect portions 532 and 533 are formed so as to pass along a vertical straight line A in which the connection holes 52 are arranged.
　この接合金物１ｄは、図１６～図１８に示すように、固定板４と連結板５の境界である曲げ部９上に補強リブ１０が設けられているものである。補強リブ１０は、図１６及び図１７に示すように、鉛直方向において、隣接する固定孔４１の間にそれぞれ位置するように設けられている。 The metal fitting 1d is provided with a reinforcing rib 10 on a bent portion 9 which is a boundary between the fixed plate 4 and the connecting plate 5 as shown in FIGS. As shown in FIGS. 16 and 17, the reinforcing ribs 10 are provided so as to be positioned between the adjacent fixing holes 41 in the vertical direction.
　補強リブ１０は、例えば、プレス加工等により、図１８に示すように、上面視略三角形状で内側に突出するように形成される。従って、図１６（ｂ）に示すように、接合金物１ｄを外側から見た場合には、連結板５の基端側の外面には、平面視略三角形状の凹部が形成される。また、同様に、図１７に示すように、固定板４の背面部４２にも平面視略三角形状の凹部が形成される。このように、接合金物１ｄでは、曲げ部９上に補強リブ１０を設けることにより、曲げ部９の強度を向上させることができるので、固定板４を高トルクでボルト等の固定具で締め付けた際に、一対の連結板５が図２７に示すように、倒れてしまうのを抑制することができる。 The reinforcing rib 10 is formed, for example, by pressing or the like so as to protrude inward in a substantially triangular shape in a top view as shown in FIG. Therefore, as shown in FIG. 16B, when the metal joint 1d is viewed from the outside, a concave portion having a substantially triangular shape in plan view is formed on the outer surface on the base end side of the connecting plate 5. Similarly, as shown in FIG. 17, a concave portion having a substantially triangular shape in plan view is also formed on the back surface portion 42 of the fixing plate 4. In this way, in the joint hardware 1d, the strength of the bent portion 9 can be improved by providing the reinforcing rib 10 on the bent portion 9, and therefore, the fixing plate 4 is fastened with a fixture such as a bolt with high torque. At this time, the pair of connecting plates 5 can be prevented from falling as shown in FIG.
　尚、本実施形態では、図１に示す第１の実施形態に係る接合金物１のように連結板５にピン溝５１の下方側の周囲を切り欠いて形成された第６欠損部５３１と、連結孔５２の周囲を切り欠いて形成された複数の第２欠損部５３２、５３３とが形成された接合金物に補強リブ１０を設けた例を示しているが、連結板５の構造はこれに限定されるものではなく、図３～図９に示す他の連結板５ａ～５ｃを有する接合金物１ａ～１ｃにも適用できるものである。また、後述する他の実施形態についても同様である。 In the present embodiment, a sixth deficient portion 531 formed by cutting out the periphery of the lower side of the pin groove 51 in the connecting plate 5 as in the metal joint 1 according to the first embodiment shown in FIG. Although the example in which the reinforcing rib 10 is provided on the joint metal in which the plurality of second defect portions 532 and 533 formed by cutting out the periphery of the connection hole 52 is shown, the structure of the connection plate 5 is shown in FIG. The present invention is not limited, and the present invention can also be applied to the joint hardware 1a to 1c having the other connecting plates 5a to 5c shown in FIGS. The same applies to other embodiments described later.
　次に、本発明の第６の実施形態に係る接合金物１ｅについて、図１９及び図２０を参照しつつ説明する。この接合金物１ｅは、図１９及び図２０に示すように、固定板４に固定板補強ビード１１が設けられたものである。 Next, a metal joint 1e according to a sixth embodiment of the present invention will be described with reference to FIGS. As shown in FIGS. 19 and 20, the metal joint 1 e is obtained by providing a fixed plate reinforcing bead 11 on the fixed plate 4.
　固定板補強ビード１１は、図１９及び図２０に示すように、固定孔４１の左右両側に設けられており、固定孔４１の周囲を囲むように、固定孔４１を中心とする円弧が鉛直方向に複数連なった形状に形成されている。この固定板補強ビード１１は、例えば、プレス加工等により、図２０に示すように、固定板４の背面部４２から内側（連結板４の突出方向）に向けて突出するように形成されている。従って、図１９に示すように、接合金物１ｅを外側から見た場合には、固定板４の背面部４２には、固定孔４１を中心とする円弧が鉛直方向に複数連なった形状の凹部が形成される。このように、接合金物１ｅでは、支持材２の側面と当接する固定板４の背面部４２から連結板５の突出方向に向けて突出する固定板補強ビード１１が設けられているので、固定板４の剛性を向上させることができ、固定板４をボルト等の固定具で締め付けた際に、一対の連結板５が倒れてしまうのを抑制することができる。 As shown in FIGS. 19 and 20, the fixing plate reinforcing beads 11 are provided on both the left and right sides of the fixing hole 41, and an arc centered on the fixing hole 41 is formed in the vertical direction so as to surround the fixing hole 41. Are formed in a plurality of continuous shapes. The fixed plate reinforcing bead 11 is formed so as to protrude inward (in the protruding direction of the connecting plate 4) from the back surface portion 42 of the fixed plate 4 by, for example, pressing or the like, as shown in FIG. . Accordingly, as shown in FIG. 19, when the metal joint 1 e is viewed from the outside, the back surface portion 42 of the fixing plate 4 has a concave portion having a shape in which a plurality of arcs centered on the fixing hole 41 are arranged in the vertical direction. It is formed. Thus, in the metal joint 1e, the fixing plate reinforcing bead 11 protruding in the protruding direction of the connecting plate 5 from the back surface portion 42 of the fixing plate 4 that contacts the side surface of the support member 2 is provided. 4 can be improved, and the pair of connecting plates 5 can be prevented from falling when the fixing plate 4 is fastened with a fixing tool such as a bolt.
　図２１に示す本発明の第７の実施形態に係る接合金物１ｆは、第６の実施形態に係る接合金物１ｅのように固定板４に固定板補強ビード１１が設けられたものに、第５の実施形態に係る接合金物１ｄの補強リブ１０を更に設けたものである。接合金物１ｆでは、図２１に示すように、固定板補強ビード１１に干渉しないように、補強リブ１１が曲げ部９上に形成されている。このように、固定板補強ビード１１と補強リブ１０とを組み合わせるようにしても良い。これにより、固定板４の剛性を向上させると共に、曲げ部９の強度を高めることができる。 A metal fitting 1f according to the seventh embodiment of the present invention shown in FIG. 21 is the same as the metal fitting 1e according to the sixth embodiment, except that a fixing plate reinforcing bead 11 is provided on the fixing plate 4. The reinforcing rib 10 of the metal joint 1d according to the embodiment is further provided. In the joint hardware 1f, as shown in FIG. 21, the reinforcing rib 11 is formed on the bent portion 9 so as not to interfere with the fixed plate reinforcing bead 11. In this manner, the fixed plate reinforcing bead 11 and the reinforcing rib 10 may be combined. Thereby, the rigidity of the fixed plate 4 can be improved and the strength of the bent portion 9 can be increased.
　次に、本発明の第８の実施形態に係る接合金物１ｇについて、図２２～図２４を参照しつつ説明する。接合金物１ｇは、図２２～図２４に示すように、固定板４と連結板５の境界である曲げ部９を通って連結板５から固定板４へと連なるように曲げ部補強ビード１２が設けられているものである。 Next, a metal joint 1g according to an eighth embodiment of the present invention will be described with reference to FIGS. As shown in FIGS. 22 to 24, the joint hardware 1g has a bent portion reinforcing bead 12 passing through the bent portion 9 which is the boundary between the fixed plate 4 and the connecting plate 5 so as to continue from the connecting plate 5 to the fixed plate 4. It is provided.
　曲げ部補強ビード１２は、図２２に示すように、鉛直方向において、隣接する固定孔４１の間にそれぞれ位置するように設けられている。曲げ部補強ビード１２は、例えば、プレス加工等により、図２４に示すように、内側に向けて突出するように形成されており、上面視略Ｌ字状に形成されている。この曲げ部補強ビード１２は、図２２及び図２３に示すように、固定板４側には、幅Ｌ８で、曲げ部９から水平方向に所定距離Ｗ８だけ直線状に延びるように形成されており、連結板５側には、固定板４側と同様の幅Ｌ８で、当該連結板５の基端（曲げ部９）から先端側へ水平方向に所定距離Ｗ９だけ直線状に延びるように形成されている。従って、固定板４の背面部４２には、図２２に示すように、接合金物１ｇを外側から見た場合には、曲げ部９から水平方向に所定距離Ｗ８延びる凹部が形成され、連結板５の外面には、図２３に示すように、当該連結板５の曲げ部９から先端側へ水平方向に所定距離Ｗ９延びる凹部が形成される。このように、接合金物１ｇでは、曲げ部９を通って連結板５から固定板４へと連なるように曲げ部補強ビード１２を設けることにより、曲げ部９の強度を向上させることができるので、固定板４を高トルクでボルト等の固定具で締め付けた際に、一対の連結板５が倒れてしまうのを抑制することができる。また、曲げ部補強ビード１２は、固定板４及び連結板５の水平方向にそれぞれ所定距離Ｗ８及びＷ９延びるように設けられているので、固定板４及び連結板５の曲げ部９付近の強度を高めることができる。 The bending part reinforcement bead 12 is provided so as to be positioned between adjacent fixing holes 41 in the vertical direction, as shown in FIG. The bending portion reinforcing bead 12 is formed so as to protrude inward as shown in FIG. 24 by, for example, pressing or the like, and is formed in a substantially L shape in a top view. As shown in FIGS. 22 and 23, the bent portion reinforcing bead 12 is formed on the fixed plate 4 side so as to have a width L8 and extend linearly from the bent portion 9 by a predetermined distance W8 in the horizontal direction. The connecting plate 5 side is formed to have a width L8 similar to that of the fixed plate 4 side and extend linearly from the base end (bending portion 9) of the connecting plate 5 to the distal end side by a predetermined distance W9 in the horizontal direction. ing. Therefore, as shown in FIG. 22, when the bonding hardware 1g is viewed from the outside, a concave portion extending in the horizontal direction from the bending portion 9 by a predetermined distance W8 is formed on the back surface portion 42 of the fixed plate 4. As shown in FIG. 23, a concave portion extending in the horizontal direction from the bent portion 9 of the connecting plate 5 to the distal end side is formed on the outer surface of the connecting plate 5. Thus, in the joint hardware 1g, the strength of the bent portion 9 can be improved by providing the bent portion reinforcing bead 12 so as to continue from the connecting plate 5 to the fixed plate 4 through the bent portion 9. When the fixing plate 4 is fastened with a fixing tool such as a bolt with high torque, the pair of connecting plates 5 can be prevented from falling down. Further, since the bending portion reinforcing beads 12 are provided so as to extend by the predetermined distances W8 and W9 in the horizontal direction of the fixing plate 4 and the connecting plate 5, respectively, the strength of the fixing plate 4 and the connecting plate 5 near the bent portion 9 is increased. Can be increased.
　次に、本発明の第９の実施形態に係る接合金物１ｈについて、図２５及び図２６を参照しつつ説明する。接合金物１ｈは、図２５及び図２６に示すように、固定板４と連結板５の境界である曲げ部９を通って連結板５から固定板４へと連なるように曲げ部補強ビード１２ａと、固定板４の幅方向の両端部に、鉛直方向に長尺に形成される端部補強ビード１３とが設けられているものである。 Next, a metal joint 1h according to a ninth embodiment of the present invention will be described with reference to FIGS. As shown in FIGS. 25 and 26, the joint hardware 1 h passes through the bending portion 9, which is the boundary between the fixed plate 4 and the connecting plate 5, and is connected to the bent portion reinforcing bead 12 a and the connecting plate 5 to the fixed plate 4. The both ends of the fixing plate 4 in the width direction are provided with end reinforcing beads 13 that are elongated in the vertical direction.
　曲げ部補強ビード１２ａは、第８の実施形態に係る接合金物１ｇに設けられる曲げ部補強ビード１２よりも鉛直方向に短い間隔で複数設けられている。また、曲げ部補強ビード１２ａの幅Ｌ９は、８の実施形態に係る接合金物１ｇに設けられる曲げ部補強ビード１２の幅Ｌ８よりも幅広に形成されている。 A plurality of bent portion reinforcing beads 12a are provided at intervals shorter in the vertical direction than the bent portion reinforcing beads 12 provided in the joint hardware 1g according to the eighth embodiment. The width L9 of the bent portion reinforcing bead 12a is formed wider than the width L8 of the bent portion reinforcing bead 12 provided in the joint hardware 1g according to the eighth embodiment.
　端部補強ビード１３は、図２５に示すように、幅Ｗ１０が曲げ部補強ビード１２ａの固定板４側に曲げ部９から水平方向に延びる寸法よりも長く形成されている。この端部補強ビード１３は、固定板４の両端部の鉛直方向（縦方向）に亘って形成されている。端部補強ビード１３は、例えば、プレス加工等により、固定板４の背面部４２から内側（連結板４の突出方向）に向けて突出するように形成されている。従って、図２５に示すように、接合金物１ｈを外側から見た場合には、固定板４の背面部４２の両端には、鉛直方向に長尺な形状の凹部が形成される。尚、本実施形態では、端部補強ビード１３が固定板４の両端部の鉛直方向に亘って形成されている例を示しているが、これに限定されるものではなく、固定板４の鉛直方向の途中で途切れるように形成されていても良い。このように、接合金物１ｈでは、固定板の幅方向の両端部に端部補強ビード１３を設けているので、固定板の幅方向両端の強度を向上させることができる。 As shown in FIG. 25, the end portion reinforcing bead 13 has a width W10 that is longer than the dimension extending in the horizontal direction from the bent portion 9 on the fixed plate 4 side of the bent portion reinforcing bead 12a. The end reinforcing beads 13 are formed across the vertical direction (vertical direction) of both end portions of the fixed plate 4. The end portion reinforcing beads 13 are formed so as to protrude from the back surface portion 42 of the fixed plate 4 toward the inside (the protruding direction of the connecting plate 4) by, for example, pressing. Therefore, as shown in FIG. 25, when the metal joint 1 h is viewed from the outside, concave portions having a shape elongated in the vertical direction are formed at both ends of the back surface portion 42 of the fixing plate 4. In the present embodiment, an example in which the end reinforcing beads 13 are formed in the vertical direction of both end portions of the fixed plate 4 is shown, but the present invention is not limited thereto, and the vertical plate of the fixed plate 4 is not limited thereto. You may form so that it may interrupt in the middle of a direction. Thus, in the joint hardware 1h, since the end reinforcement beads 13 are provided at both ends in the width direction of the fixed plate, the strength at both ends in the width direction of the fixed plate can be improved.
　以下、本発明に係る接合金物１ｄ～１ｇの固定板４を図２７に示すように、ボルト６で締め付けて支持材２に固定する際の一対の連結板５の変形量を測定した実験結果について説明する。ここでは、ボルトを締め付ける前の図１６に示すＱの位置における一対の連結板５の間隔Ｗ１１と、４０Ｎ・ｍ及び８０Ｎ・ｍで締め付けた際の一対の連結板５の間隔Ｗ１１の寸法を測定し、締結前の寸法に対する変形率を求めた。実験には、以下の実施例４～７、及び比較例３、４に示す形状の接合金物を用いた。尚、実施例４～７、及び比較例４の接合金物については、補強部の有無及び形状のみが異なるものであり、それ以外の形状については同じものを用いている。また、比較例３については、実施例４～７、及び比較例４よりも固定板４及び連結板５の板厚が厚いものを用いている。 Hereinafter, as shown in FIG. 27, the experimental results of measuring the amount of deformation of the pair of connecting plates 5 when the fixing plates 4 of the metal fittings 1d to 1g according to the present invention are fastened with bolts 6 and fixed to the support material 2 are shown. explain. Here, the dimension of the distance W11 between the pair of connecting plates 5 at the position Q shown in FIG. 16 before tightening the bolts and the distance W11 between the pair of connecting plates 5 when tightened at 40 N · m and 80 N · m are measured. Then, the deformation ratio relative to the dimensions before fastening was obtained. In the experiment, joint metal fittings having the shapes shown in Examples 4 to 7 and Comparative Examples 3 and 4 below were used. Note that the bonding hardware of Examples 4 to 7 and Comparative Example 4 differ only in the presence or absence of the reinforcing portion and the shape, and the other shapes are the same. In Comparative Example 3, the fixing plate 4 and the connecting plate 5 are thicker than those in Examples 4 to 7 and Comparative Example 4.

　また、実施例４～７は、比較例４のように補強を施すことなく、固定板４及び連結板５の板厚ｔを薄板化した接合金物を用いた場合に比べて、大幅に強度が向上していることがわかる。特に、８０Ｎ・ｍの高トルクにおいてはその差が大きくなっている。 Further, in Examples 4 to 7, the strength is significantly higher than that in the case of using a metal joint in which the plate thickness t of the fixing plate 4 and the connecting plate 5 is reduced without reinforcing as in the comparative example 4. It can be seen that it has improved. In particular, the difference is large at a high torque of 80 N · m.
　表２の測定結果から、実施例４～７に示すように、それぞれ補強リブ１０、固定板補強ビード１１、及び曲げ部補強ビード１２のいずれかを設けた接合金物を用いることで、高トルクでボルトを締め付けた際でも、一対の連結板５が図２７に示すように、倒れてしまうことを抑制することができる。これにより、強度を確保しつつ、固定板４及び連結板５の板厚ｔを薄板化を図ることができる。 From the measurement results in Table 2, as shown in Examples 4 to 7, by using a joint metal provided with any one of the reinforcing rib 10, the fixed plate reinforcing bead 11, and the bent portion reinforcing bead 12, the high torque can be obtained. Even when the bolt is tightened, the pair of connecting plates 5 can be prevented from falling as shown in FIG. Thereby, it is possible to reduce the thickness t of the fixing plate 4 and the connecting plate 5 while ensuring the strength.
