Description

本発明は、木部材どうしを接合するための受け金具，連結金具及び建築用接合金具に関し、特に、角棒状の受け金具と、先端部を鉤状に折り曲げた平板部材を連結させた連結金具を備えることにより、十分な接合強度を維持しつつ、受け金具の突出量を大幅に低減し、積載効率を向上させることができる受け金具，連結金具及び建築用接合金具に関する。   BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a receiving metal fitting, a connecting metal fitting, and a building connecting metal fitting for joining wooden members, and in particular, a connecting metal fitting that connects a square bar-shaped receiving metal fitting and a flat plate member whose tip is bent into a bowl shape. The present invention relates to a receiving metal fitting, a connecting metal fitting, and a building metal fitting that can significantly reduce the protruding amount of the metal fitting and improve the loading efficiency while maintaining sufficient bonding strength.

従来、梁等の横木部材と柱等の縦木部材を接合する建築用木部材の接合方法として、ほぞ加工やぬき加工を木材に施し、これら木材どうしを組み合わせて接合する方法が用いられてきた。
しかし、近年では、建築用接合金具を用いて横木部材と縦木部材を接合すると、木材どうしを組み合わせて接合することにより強固に接合でき、かつ、施工現場での作業効率を向上させることができることから、様々な構造の建築用接合金具が提案されている。 Conventionally, as a method of joining a wooden member for construction that joins a cross member such as a beam and a vertical member such as a column, a method of applying mortise processing or unpiercing processing to wood and combining these pieces of wood has been used. .
However, in recent years, if a cross member and a vertical member are joined using a construction fitting, it can be firmly joined by joining wood together, and work efficiency at the construction site can be improved. Therefore, various types of construction metal fittings have been proposed.

たとえば、特許文献１には、梁などの横架材の端部に対向して止着される、先端部を折り曲げた係止片を有する平板状の一対の接合金物と、接合金物の先端側の上方に、横架材を貫通して架設される掛止杆と、対向する係止片の隙間を貫通した状態で、上記掛止杆を受支する、柱や胴差などの構造材の側面に突設された第一突子と、第一突子の下方であって、かつ、構造材の側面に、上記隙間を貫通した状態で突設された適宜数の第二突子と、第二突子に掛止される第二掛止杆と、第一突子と第二突子の一方又は双方の下部に係止される係止杆とを備えた横架材の接合装置の技術が開示されている。   For example, in Patent Document 1, a pair of flat metal fittings each having a locking piece bent at a front end portion, which are fixed to be opposed to an end portion of a horizontal member such as a beam, and a front end side of the joint hardware Of the structural member such as a column or trunk that receives and supports the above-mentioned latching rod while penetrating through the gap between the latching rods installed through the horizontal member and the opposing locking pieces. A first protrusion projecting on the side surface, and an appropriate number of second projecting members projecting in a state of passing through the gap on the side surface of the structural material, below the first projecting element, An apparatus for joining horizontal members, comprising: a second hook that is hooked to the second protrusion; and a locking hook that is locked to a lower portion of one or both of the first protrusion and the second protrusion. Technology is disclosed.

また、特許文献２には、柱などの主幹部材から突設する基本金物（受け金具）と、梁などの結合部材内に収容される付属金物（連結金具）からなり、基本金物が、支持板と、この支持板から突出しかつ結合部材の端部に形成された係合溝に嵌り込む、対向した一対の接合板を有し、付属金物が、係合溝と連通する嵌合溝に嵌り込む接続板を有する、木造建築部材の連結金物の技術が開示されている。
特開２００３−１８４１８１号公報 特開２００４−２７０２５４号公報 Further, Patent Document 2 includes a basic hardware projecting from a main member such as a pillar (receiving metal fitting) and an accessory hardware (connecting metal fitting) accommodated in a coupling member such as a beam. And a pair of opposing joining plates that protrude from the support plate and fit into the engaging groove formed at the end of the coupling member, and the accessory fitting fits into the fitting groove that communicates with the engaging groove. A technique for connecting hardware of a wooden building member having a connection plate is disclosed.
JP 2003-184181 A JP 2004-270254 A

しかしながら、特許文献１に開示された横架材の接合装置は、掛止杆，第二掛止杆及び係止杆が、各突子に対して掛止及び係止することにより、接合する構造としてあり、十分な接合強度を得ることができないといった根本的な問題があった。
また、特許文献２に開示された木造建築部材の連結金物は、十分な接合強度を実現するには、接合板に穿設された通孔から接合板の端部までの距離を確保する必要があり、基本金物（受け金具）の突出量を低減しすぎると、接合強度が低下するといった問題があった。 However, the horizontal member joining apparatus disclosed in Patent Document 1 has a structure in which a latching rod, a second latching rod, and a locking rod are joined to each protrusion by latching and locking. There was a fundamental problem that sufficient joint strength could not be obtained.
Moreover, in order to achieve a sufficient joint strength, the connecting hardware of the wooden building member disclosed in Patent Document 2 needs to secure a distance from the through hole formed in the joint plate to the end of the joint plate. In addition, there is a problem in that the bonding strength decreases when the protruding amount of the basic hardware (the metal fitting) is excessively reduced.

さらに、近年、様々な構造の優れた建築用接合金具が商品化されているが、接合金具の取付け作業や木部材どうしの接合作業における作業効率をさらに向上させることが要望されていた。たとえば、梁に取り付けられる連結金具が対向する一対の連結板を有し、柱に固定される受け金具が対向する一対の平板部材を有する構成の建築用接合金具においては、上記平板部材と連結板に連結ピンを係入させる際、一方の連結板と平板部材に連結ピンが斜めに挿入されると、他方の平板部材と連結板のピン挿入孔に連結ピンを挿入しずらくなり、作業性が低下するといった問題があった。また、接合強度を維持しつつ受け金具の突出量を大幅に低減し、積載効率を向上させる点に関しては、さらなる技術改良が要望されていた。   Furthermore, in recent years, excellent architectural fittings having various structures have been commercialized, but there has been a demand for further improving the work efficiency in the fitting work of the fittings and the joining work of the wooden members. For example, in a construction joint fitting having a pair of connecting plates attached to a beam and having a pair of connecting plates opposed to each other and a receiving member fixed to a column facing the connecting plate, the flat plate member and the connecting plate When the connecting pin is inserted into the connecting plate, if the connecting pin is obliquely inserted into one connecting plate and the flat plate member, it becomes difficult to insert the connecting pin into the pin insertion hole of the other flat plate member and the connecting plate. There has been a problem of lowering. Further, there has been a demand for further technical improvements in terms of significantly reducing the protruding amount of the metal fitting while maintaining the bonding strength and improving the loading efficiency.

本発明は、上記諸問題を解決すべく、十分な接合強度を維持しつつ、受け金具の突出量を大幅に低減し、積載効率を向上させることができる受け金具，連結金具及び建築用接合金具の提供を目的とする。   In order to solve the above-described problems, the present invention provides a receiving metal fitting, a connecting metal fitting, and a building metal fitting that can significantly reduce the protruding amount of the receiving metal and improve the loading efficiency while maintaining sufficient bonding strength. The purpose is to provide.

この目的を達成するために、本発明の受け金具は、木部材どうしを接合するため、ボルトによって前記木部材の一方の木部材に固定される受け金具であって、角棒状の受け金具本体を備え、この受け金具本体には、正面から背面にかけて、前記ボルトの挿入されるボルト孔が貫設され、かつ、一方の側面から他方の側面にかけて、前記木部材の他方の木部材に取り付けられた連結金具と連結するための連結ピンが挿入される連結ピン孔が貫設され、さらに、前記受け金具本体の少なくとも一端部に、前記連結金具の被係止部が係入される係止部が形成された構成としてある。   In order to achieve this object, the metal fitting of the present invention is a metal fitting fixed to one wooden member of the wooden member by a bolt in order to join the wooden members, and a rectangular bar-shaped metal fitting body is provided. The bolt body is provided with a bolt hole through which the bolt is inserted from the front side to the back side, and attached to the other wooden member of the wooden member from one side surface to the other side surface. A connection pin hole into which a connection pin for connecting to the connection metal fitting is inserted, and a locking portion into which a locked portion of the connection metal fitting is inserted into at least one end of the receiving metal fitting body. As a formed configuration.

このように、受け金具本体を角棒状とすることにより、受け金具の機械的強度を向上させることができるので、受け金具を小型化することができるとともに、一方の木部材（たとえば、柱）からの受け金具の突出量を大幅に低減させることができる。これにより、受け金具を一方の木部材に固定したとき、一方の木部材からの受け金具の突出量を低減することができ、たとえば、プレカット工場で受け金具が固定された一方の木部材を、施工現場まで輸送する際、一方の木部材をかさばることなく効率よくトラックに積めるので、積載効率を向上させることができる。
また、係止部に他方の木部材（たとえば、梁）を係止することができるので、接合作業を容易かつ安全に行うことができる。さらに、構造が単純化できるので、製造原価のコストダウンを図ることができる。 Thus, since the mechanical strength of the metal fitting can be improved by making the metal fitting body into a square bar shape, the metal fitting can be reduced in size and from one wooden member (for example, a pillar). The amount of protrusion of the receiving bracket can be greatly reduced. Thereby, when the metal fitting is fixed to one wooden member, the protruding amount of the metal fitting from one wooden member can be reduced, for example, one wooden member to which the metal fitting is fixed at a pre-cut factory, When transporting to a construction site, one wooden member can be efficiently loaded on the truck without being bulky, so that loading efficiency can be improved.
Moreover, since the other wooden member (for example, beam) can be latched by the latching | locking part, joining work can be performed easily and safely. Furthermore, since the structure can be simplified, the manufacturing cost can be reduced.

また、本発明の受け金具は、前記受け金具本体の両端部に前記係止部を形成し、さらに、前記受け金具本体の長手方向の中央位置に対し、対称となるように二以上の前記連結ピン孔を貫設し、かつ、穿設された各前記連結ピン孔から、前記長手方向の一方向に同じ距離だけ離して、前記ボルト孔を貫設した構成としてある。
このようにすると、他方の木部材を直交取付けする際、第二の受け金具を長手方向に反転させて一方の木部材に固定するだけでよく、受け金具の共用化を図ることができる。 Further, in the metal fitting of the present invention, the locking portions are formed at both end portions of the metal fitting body, and two or more of the couplings are symmetric with respect to the longitudinal center position of the metal fitting body. A pin hole is penetrated, and the bolt hole is penetrated by being separated from each of the drilled connecting pin holes by the same distance in one direction of the longitudinal direction.
If it does in this way, when attaching the other wooden member orthogonally, it is only necessary to invert the second receiving metal fitting in the longitudinal direction and fix it to the one wooden member, so that the common receiving metal can be used.

また、上記目的を達成するために、本発明の連結金具は、木部材どうしを接合するため、被接合側の前記木部材に取り付けられる連結金具であって、対向する二枚の平板部材と、前記平板部材を連結する連結部材を備え、前記平板部材に、被接合側の前記木部材に取り付けるための取付け部材が挿入される取付け孔が穿設され、かつ、接合側の前記木部材に固定された受け金具と連結するための、連結ピンが挿入される連結ピン孔が穿設され、さらに、前記連結部材が、前記受け金具に形成された係止部に係入される構成としてある。
このようにすると、連結金具の一体化を図ることによって、被接合側の木部材（たとえば、梁）に容易に取り付けることができ、また、受け金具の係止部によって連結部材が係止されるので、接合作業を容易かつ安全に行うことができる。 Further, in order to achieve the above object, the connection fitting of the present invention is a connection fitting attached to the wood member on the joined side in order to join the wooden members, and two opposing flat plate members, A connecting member for connecting the flat plate member is provided, and the flat plate member is provided with a mounting hole into which a mounting member for mounting to the bonded wooden member is inserted, and fixed to the bonded wooden member. A connection pin hole into which a connection pin is inserted is formed to connect to the received metal fitting, and the connection member is engaged with a locking portion formed in the metal fitting.
If it does in this way, it can attach to a to-be-joined wooden member (for example, beam) easily by aiming at integration of a connection metal fitting, and a connection member is latched by a latching part of a receiving metal fitting. Therefore, the joining operation can be performed easily and safely.

また、本発明の連結金具は、前記連結部材を、前記連結部材用孔に挿入した状態で、前記平板部材に溶接した構成としてある。
このようにすると、連結部材と平板部材の接合強度を向上させることができるとともに、容易に製造することができるので、製造原価のコストダウンを図ることができる。 Moreover, the connection metal fitting of this invention is set as the structure welded to the said flat plate member in the state inserted in the said hole for connection members.
If it does in this way, while being able to improve the joint strength of a connection member and a flat plate member and being able to manufacture easily, the cost reduction of manufacturing cost can be aimed at.

また、本発明の連結金具は、前記二枚の平板部材の先端部をそれぞれ向き合う方向に鉤状に折り曲げて、折り曲げ部を形成し、かつ、前記平板部材の後端部に、前記連結ピン孔を穿設した構成としてある。
このようにすると、折り曲げ部によって、先端部の機械的強度が向上するので、接合側の木部材（たとえば、柱）側の端部のより端に接近した位置に、連結ピン孔を穿設することができる。これにより、接合側の木部材からの受け金具の突出量を低減することができるので、たとえば、プレカット工場で受け金具が固定された接合側の木部材を、施工現場まで輸送する際、接合側の木部材をかさばることなく効率よくトラックに積むことができ、積載効率を向上させることができる。 Further, the connection fitting of the present invention is formed by bending the front end portions of the two flat plate members in a hook shape in the facing direction to form a bent portion, and the connection pin hole is formed at the rear end portion of the flat plate member. It is set as the structure which perforated.
In this case, the mechanical strength of the tip portion is improved by the bent portion, so that the connecting pin hole is formed at a position closer to the end of the end portion on the joining side wooden member (for example, column) side. be able to. As a result, it is possible to reduce the protruding amount of the metal fitting from the wood member on the joining side. For example, when transporting the wood member on the joining side to which the metal fitting is fixed at the precut factory to the construction site, the joint side The wooden members can be efficiently loaded on the truck without being bulky, and the loading efficiency can be improved.

また、本発明の連結金具は、前記二枚の平板部材における折り曲げ部の隙間の距離を、前記受け金具本体の正面幅とほぼ同じとした構成としてある。
このようにすると、鉤状に折り曲げられた折り曲げ部の隙間に、受け金具を嵌入させることができ、連結金具の左右方向への移動を受け金具が係止し抑制するので、左右方向に対する接合強度を向上させることができる。また、連結部材を受け金具の係止部に係入させる際、両折り曲げ部が、連結金具を導くガイドとして機能するので、係入作業をより容易に行うことができる。 Moreover, the connection metal fitting of this invention is set as the structure which made the distance of the clearance gap between the bending parts in the said 2 flat plate member substantially the same as the front width of the said receiving metal fitting main body.
In this way, the receiving metal fitting can be inserted into the gap between the bent portions bent in a bowl shape, and the metal fitting is locked and restrained in response to the movement of the connecting metal fitting in the left-right direction. Can be improved. Further, when the connecting member is engaged with the engaging portion of the metal fitting, the both bent portions function as a guide for guiding the coupling metal, so that the engagement operation can be performed more easily.

また、上記目的を達成するために、本発明の建築用接合金具は、木部材どうしを接合するため、前記木部材の一方の木部材に固定される受け金具と、前記木部材の他方の木部材に取り付けられる連結金具を有する建築用接合金具であって、上記請求項１又は２に記載された前記受け金具と、上記請求項３〜６のいずれかに記載された前記連結金具とを具備した構成としてある。
このように、本発明は、建築用接合金具の発明としても有効である。 In order to achieve the above object, the architectural fitting of the present invention includes a receiving fitting fixed to one wooden member of the wooden member and the other wooden member of the wooden member for joining the wooden members together. A construction fitting having a connecting fitting attached to a member, comprising: the receiving fitting according to claim 1 or 2; and the connecting fitting according to any one of claims 3 to 6. It is as a configuration.
Thus, this invention is effective also as invention of the joining metal fitting for construction.

本発明における受け金具，連結金具及び建築用接合金具によれば、十分な接合強度を維持しつつ、受け金具の突出量を大幅に低減し、積載効率を向上させることができる。また、連結金具の取付け作業や木部材どうしの接合作業における作業効率をさらに向上させるとともに、廉価な受け金具，連結金具及び建築用接合金具を提供することができる。   According to the receiving metal fitting, the connecting metal fitting, and the architectural fitting in the present invention, it is possible to greatly reduce the protruding amount of the receiving metal and improve the loading efficiency while maintaining sufficient bonding strength.

[第一実施形態]
図１は、本発明の第一実施形態にかかる建築用接合金具の概略斜視図を示している。
同図において、建築用接合金具１は、縦木部材である柱５に横木部材である梁６を接合する接合金具であって、柱５の側面に、ボルト４１，ナット４２及び平座金４３によって固定される受け金具２と、梁６の端部に、取付け部材である連結金具固定ピン４４によって取り付けられる連結金具３を備え、連結ピン４５を後打ちすることによって、梁６と柱５を接合させる構成としてある。
なお、柱５に梁６を接合する例について説明するが、この例に限定されないことはもちろんである。 [First embodiment]
FIG. 1: has shown the schematic perspective view of the joining metal fitting for construction concerning 1st embodiment of this invention.
In FIG. 1, a construction joint 1 is a joint that joins a beam 6 that is a cross member to a column 5 that is a vertical member, and a bolt 41, a nut 42, and a plain washer 43 are attached to the side of the pillar 5. The receiving metal fitting 2 to be fixed and the connecting metal fitting 3 attached to the end of the beam 6 by the connecting metal fixing pin 44 as an attaching member are provided. This is a configuration to be made.
In addition, although the example which joins the beam 6 to the pillar 5 is demonstrated, of course, it is not limited to this example.

（受け金具）
図２は、本発明の第一実施形態にかかる建築用接合金具の受け金具の概略図であり、（ａ）は斜視図を、（ｂ）は拡大正面図を、（ｃ）は拡大側面図を示している。
同図において、受け金具２は、四角棒状の角鋼からなる受け金具本体２１を備え、受け金具本体２１の正面から背面にかけて、柱５に固定するためのボルト４１が挿入されるボルト孔２２を、上部，中央部及び下部の三箇所に貫設してある。また、梁６に取り付けられた連結金具３と連結するための、連結ピン４５が挿入される連結ピン孔２３を、受け金具本体２１の一方の側面から他方の側面にかけて、上部，中央部及び下部の三箇所に貫設してある。このようにして、受け金具２を角棒状とすると、機械的強度を向上させることができるので、受け金具２を小型化して、柱５からの受け金具２の突出量を大幅に低減させることができる。これにより、たとえば、プレカット工場で受け金具２が固定された柱５を、施工現場まで輸送する際、柱５からの受け金具２の突出量が少なくなるので、木部材をかさばることなく効率よくトラックに積め、積載効率を向上させることができる。 (Receiver bracket)
FIG. 2 is a schematic view of a receiving metal fitting for a construction metal fitting according to the first embodiment of the present invention, in which (a) is a perspective view, (b) is an enlarged front view, and (c) is an enlarged side view. Is shown.
In the same figure, the metal fitting 2 includes a metal fitting body 21 made of square bar-shaped square steel, and a bolt hole 22 into which a bolt 41 for fixing to a pillar 5 is inserted from the front surface to the back surface of the metal fitting body 21. It penetrates in three places, upper part, central part and lower part. Further, the connecting pin hole 23 into which the connecting pin 45 is inserted for connecting to the connecting metal 3 attached to the beam 6 is formed from one side surface to the other side surface of the receiving metal body 21 at the upper part, the central part and the lower part. It is penetrated in three places. In this way, the mechanical strength can be improved when the bracket 2 has a square bar shape. Therefore, the bracket 2 can be miniaturized and the amount of protrusion of the bracket 2 from the column 5 can be greatly reduced. it can. Thus, for example, when the pillar 5 to which the bracket 2 is fixed at the precut factory is transported to the construction site, the amount of projection of the bracket 2 from the pillar 5 is reduced, so that the truck can be efficiently tracked without bulking the wooden member. It is possible to improve the loading efficiency.

さらに、受け金具２は、受け金具本体２１の一端に、背面側から中央部に掛けて切欠部２４２を設け、後述するピン３２が係入される係止部２４を形成してある。この係止部２４は、正面側に位置する壁部２４０の先端にガイド面２４１が形成してあり、ピン３２を係止部２４へ容易に係入できるようにしてある。
なお、受け金具２は、受け金具本体２１の下端に、上端の係止部２４と同様の係止部２４´を形成してもよく、このようにすると、受け金具本体２１を長手方向に反転させて、柱５に固定して使用することができる。 Furthermore, the receiving metal fitting 2 is provided with a notch 242 at one end of the receiving metal body 21 from the back side to the center, and a locking portion 24 into which a pin 32 described later is engaged. The locking portion 24 has a guide surface 241 formed at the tip of the wall portion 240 located on the front side so that the pin 32 can be easily engaged with the locking portion 24.
In addition, the catch 2 may be formed with a locking portion 24 ′ similar to the locking portion 24 at the upper end at the lower end of the catch body 21, and in this way, the catch body 21 is inverted in the longitudinal direction. It can be used by being fixed to the pillar 5.

また、受け金具２は、受け金具本体２１の長手方向の中央位置２０に対し、対称となるように（中央位置２０から距離Ｈだけ離れた位置に）二以上の連結ピン孔２３を貫設し、かつ、貫設された各連結ピン孔２３から、長手方向の一方向に同じ距離Δｈだけ離して、ボルト孔２２を貫設してある。本実施形態では、受け金具本体２１の中央位置２０，上部及び下部の三箇所に連結ピン孔２３を貫設し、各連結ピン孔２３から上方向に同じ距離だけ離して、三箇所にボルト孔２２を貫設してある。このようにすると、図３に示すように、梁６を直交して取り付けるため、柱５の直交する面にそれぞれ受け金具２を取り付ける際、一方の受け金具２を長手方向に反転させて柱５に固定することにより、直交する受け金具２のボルト孔２２に挿入されるボルト４１どうしの柱５内での干渉を防止することができる。
これにより、一種類の受け金具２でありながら、異なった態様での使用が可能となり、組合せて同時に使用することも可能となる。 Further, the receiving metal fitting 2 has two or more connecting pin holes 23 penetrating so as to be symmetrical with respect to the central position 20 in the longitudinal direction of the receiving metal body 21 (at a distance H from the central position 20). In addition, the bolt holes 22 are provided so as to be separated from the connecting pin holes 23 provided therethrough by the same distance Δh in one direction in the longitudinal direction. In the present embodiment, connecting pin holes 23 are provided at three positions of the center position 20 and the upper and lower portions of the receiving metal body 21, and are separated from each connecting pin hole 23 by the same distance upward, and bolt holes are formed at three positions. 22 is penetrated. In this way, as shown in FIG. 3, in order to attach the beam 6 orthogonally, when attaching the receiving metal fittings 2 to the orthogonal surfaces of the pillars 5, one of the receiving metal fittings 2 is inverted in the longitudinal direction to make the pillar 5 It is possible to prevent interference between the bolts 41 inserted into the bolt holes 22 of the orthogonal receiving metal fittings 2 in the pillar 5.
Thereby, although it is one type of receiving metal fitting 2, it can be used in different modes and can be used simultaneously in combination.

また、受け金具２は、横断面が正四角形としてあり、このようにすると、ほぼ同じ直径の連結ピン孔２３とボルト孔２２を貫設することができるので、受け金具２の小型化を図ることができる。しかし、横断面は正四角形に限定されるものではない。
なお、本実施形態の受け金具２は、両端に係止部２４，２４´を形成し、一方の受け金具２を長手方向に反転させて柱５に固定することを可能とした構造としてあるが、この構造に限定されるものではない。たとえば、図４に示すように、上端にのみ係止部２４を形成してもよく、また、受け金具本体２１の一方の側面から他方の側面にかけて、中央部及び下部の二箇所に連結ピン孔２３を貫設した構造としてもよい。 Further, the receiving metal fitting 2 has a square shape in cross section, and in this way, the connecting pin hole 23 and the bolt hole 22 having substantially the same diameter can be penetrated, so that the receiving metal fitting 2 can be miniaturized. Can do. However, the cross section is not limited to a regular square.
In addition, although the receiving metal fitting 2 of this embodiment forms the latching | locking parts 24 and 24 'at both ends, it has a structure which made it possible to invert one receiving metal fitting 2 and to fix to the pillar 5 in a longitudinal direction. The structure is not limited to this. For example, as shown in FIG. 4, the locking portion 24 may be formed only at the upper end, and the connecting pin hole is formed at two locations, the central portion and the lower portion, from one side surface to the other side surface of the metal fitting body 21. It is good also as a structure which 23 was penetrated.

FIG. 5 is a schematic view of a connecting fitting of a building joint fitting according to the first embodiment of the present invention, where (a) is a perspective view, (b) is an enlarged front view, and (c) is an enlarged side view. Is shown.
In the figure, a connecting bracket 3 is attached to a wooden member such as a beam 6 joined to a wooden member such as a pillar 5 and connects two opposing flat plate members 31 and the flat plate members 31 together. 2 is provided with a pin 32 that is locked to the locking portion 24 formed in the area 2.

このピン３２は、平板部材３１の先端部側の上部に穿設したピン用孔３７に挿入された状態で、平板部材３１に溶接してある。このようにすると、ピン３２がピン用孔３７に係止されるので、たとえば上下方向の外力に対して、ピン３２と平板部材３１の接合強度を向上させることができる。また、梁６の柱５側かつ上部にピン３２が設けられているので、ピン３２を係止部２４に係入させる作業を容易に行うことができ、係入作業の安全性を向上させることができる。   The pin 32 is welded to the flat plate member 31 in a state where the pin 32 is inserted into a pin hole 37 formed in the upper portion of the flat plate member 31 on the distal end side. If it does in this way, since the pin 32 is latched by the hole 37 for pins, the joint strength of the pin 32 and the flat plate member 31 can be improved with respect to the external force of an up-down direction, for example. Moreover, since the pin 32 is provided on the column 5 side and the upper part of the beam 6, the work of engaging the pin 32 with the engaging portion 24 can be easily performed, and the safety of the engaging operation can be improved. Can do.

また、平板部材３１は、後端部側付近の中央部及び下部に、梁６に取り付けるための部材である連結金具固定ピン４４が挿入される取付け孔３３を穿設し、先端部側付近の中央部及び下部に、受け金具２と連結するための連結ピン４５が挿入される連結ピン孔３４を穿設してある。このようにすると、連結金具３の一体化を図ることによって、連結金具３を梁６に容易に取り付けることができ、また、受け金具２の係止部２４によってピン３２が係止されるので、接合作業を容易かつ安全に行うことができる。   Further, the flat plate member 31 is provided with an attachment hole 33 into which a connecting metal fitting fixing pin 44 as a member for attaching to the beam 6 is inserted in the central portion and the lower portion in the vicinity of the rear end portion side. A connecting pin hole 34 into which a connecting pin 45 for connecting to the receiving metal fitting 2 is inserted is formed in the central portion and the lower portion. In this way, by integrating the connecting fitting 3, the connecting fitting 3 can be easily attached to the beam 6, and the pin 32 is locked by the locking portion 24 of the receiving bracket 2. The joining operation can be performed easily and safely.

また、連結金具３は、二枚の平板部材３１の先端部をそれぞれ向き合う方向に鉤状に折り曲げて、折り曲げ部３５を形成してある。このようにすると、折り曲げ部３５によって、先端部側の機械的強度が向上するので、柱５側により接近した位置に、連結ピン孔３４を穿設することができる。これにより、柱５からの受け金具２の突出量を、より低減化することができる。   In addition, the connection fitting 3 is formed with a bent portion 35 by bending the tip portions of the two flat plate members 31 in a hook shape in directions facing each other. By doing so, the bending portion 35 improves the mechanical strength on the tip side, so that the connecting pin hole 34 can be formed at a position closer to the column 5 side. Thereby, the protrusion amount of the bracket 2 from the pillar 5 can be further reduced.

また、連結金具３は、対向するように鉤状に折り曲げられた平板部材３１の折り曲げ部３５先端どうしの隙間３６の距離（幅Ｗ）を、受け金具２の正面幅とほぼ同じとするとよい。このようにすると、連結金具３が受け金具２に係止したとき、折り曲げ部３５どうしの隙間３６に受け金具２が嵌入し、連結金具３の左右方向への移動を受け金具２が抑制するので、左右方向に対する接合強度を向上させることができる。また、連結部材３を受け金具２の係止部２４に係入させる際、両折り曲げ部３５が、連結金具３を導くガイドとして機能するので、係入作業をより容易に行うことができる。なお、両折り曲げ部３５の下部に、下方に向かって幅が広がるガイド面３５１を形成すると、連結金具３が受け金具２に嵌入する際、ガイド面３５１によって連結金具３がガイドされ、係入作業をさらに容易に行うことができる。   In addition, in the connecting metal 3, the distance (width W) of the gap 36 between the ends of the bent portions 35 of the flat plate member 31 bent in a bowl shape so as to face each other is preferably substantially the same as the front width of the receiving metal 2. In this way, when the connecting metal fitting 3 is locked to the receiving metal fitting 2, the receiving metal fitting 2 is fitted into the gap 36 between the bent portions 35, and the metal fitting 2 is restrained by receiving the movement of the connecting metal fitting 3 in the left-right direction. The bonding strength in the left-right direction can be improved. Further, when the connecting member 3 is engaged with the engaging portion 24 of the metal fitting 2, the both bent portions 35 function as a guide for guiding the connection metal fitting 3, so that the engagement operation can be performed more easily. In addition, when the guide surface 351 whose width | variety expands below is formed in the lower part of both the bending parts 35, when the connection metal fitting 3 fits in the receiving metal fitting 2, the connection metal fitting 3 is guided by the guide surface 351, and engagement work Can be performed more easily.

次に、建築用接合金具の接合手順について、図面を参照して説明する。
図６は、本発明の第一実施形態にかかる建築用接合金具の接合手順を説明するための概略斜視図を示している。
建築用接合金具１は、受け金具２と連結金具３から構成されている。このうち、受け金具２は、柱５にボルト４１，ナット４２及び平座金４３によって固定されている。ここで、柱５と受け金具２に挟まれた平座金４３は、通常、厚さ約１〜２ｍｍとしてあり、ボルト４１を締め付けることにより、柱５にめり込み、平座金４３の上面が柱５の側面と同一面となるので、受け金具２が柱５にめり込み載置面２４２が狭くなるといった不具合を回避することができる。また、柱５にめり込んだ平座金４３がボルト４１及び受け金具２の位置決め部材として機能するので、梁６の上面を梁天端予定位置５１に精度よく位置決めすることができる。 Next, the joining procedure of the construction joint fitting will be described with reference to the drawings.
FIG. 6: has shown the schematic perspective view for demonstrating the joining procedure of the joining metal fittings for construction concerning 1st embodiment of this invention.
The construction fitting 1 includes a receiving fitting 2 and a connecting fitting 3. Among these, the metal fitting 2 is fixed to the column 5 with bolts 41, nuts 42, and flat washers 43. Here, the flat washer 43 sandwiched between the column 5 and the receiving metal fitting 2 is usually about 1 to 2 mm in thickness. By tightening the bolt 41, the flat washer 43 is fitted into the column 5, and the upper surface of the flat washer 43 is Since it becomes the same surface as the side surface, it is possible to avoid the problem that the receiving metal fitting 2 is fitted into the column 5 and the mounting surface 242 is narrowed. In addition, since the flat washer 43 recessed into the column 5 functions as a positioning member for the bolt 41 and the receiving metal fitting 2, the upper surface of the beam 6 can be accurately positioned at the beam top end planned position 51.

また、連結金具３は、梁６の端面に加工された切欠６１及びこの切欠６１の両側に連続して形成された二本の溝６２に平板部材３１が挿入される。そして、梁６の側面に穿設された挿入孔６３から打ち込まれた連結金具固定ピン４４が、取付け孔３３を貫通することにより、梁６に取り付けられる。ここで、連結金具３は、折り曲げ部３５の外面が梁６の端面と同一面となり、かつ、平板部材３１の下端面が梁６の下面と同一面となるように挿入されると、取付け孔３３と挿入孔６３の孔位置が一致する構成としてある。これにより、連結金具３の挿入作業及び連結金具固定ピン４４の打ち込み作業を効率よく行うことができる。
なお、通常、梁６の二本の溝６２は、既存の、溝間距離がほぼ規格化された溝加工装置によって加工されるが、本実施形態では、受け金具２の正面幅寸法が短くなっているものの、連結金具３に折り曲げ部３５を設けることにより、二枚の平板部材３１の間隔を、既存の溝加工装置の溝間距離と同じとなるようにしてある。これにより、既存の溝加工装置を用いて、従来と同じように溝加工を行うことができる。 Further, in the connection fitting 3, the flat plate member 31 is inserted into a notch 61 formed on the end surface of the beam 6 and two grooves 62 formed continuously on both sides of the notch 61. Then, the connecting fixture fixing pin 44 driven from the insertion hole 63 formed in the side surface of the beam 6 is attached to the beam 6 by passing through the attachment hole 33. Here, when the connecting fitting 3 is inserted so that the outer surface of the bent portion 35 is flush with the end face of the beam 6 and the lower end face of the flat plate member 31 is flush with the lower face of the beam 6, 33 and the insertion hole 63 have the same hole position. Thereby, the insertion operation of the connection fitting 3 and the driving operation of the connection fitting fixing pin 44 can be performed efficiently.
Normally, the two grooves 62 of the beam 6 are processed by an existing groove processing apparatus in which the distance between the grooves is substantially standardized. However, in this embodiment, the front width dimension of the receiving metal fitting 2 is shortened. However, by providing the connecting metal fitting 3 with the bent portion 35, the distance between the two flat plate members 31 is made the same as the distance between the grooves of the existing groove processing apparatus. Thereby, it is possible to perform groove processing as in the conventional case using an existing groove processing apparatus.

通常、プレカット工場で上記前段取り作業が施された柱５及び梁６は、施工現場に輸送される。この際、本実施形態の受け金具２は角棒を使用しているので、柱５からの受け金具２の突出量を大幅に低減することができる。したがって、プレカット工場で受け金具２が固定された柱５を、施工現場まで輸送する際、柱５をかさばることなく効率よくトラックに積めるので、積載効率を向上させることができる。なお、本発明の受け金具２は、柱５から突出量を大幅に低減しているが、受け金具本体２１を角鋼としてあるので、十分強固な機械的強度を維持することができる。   Usually, the column 5 and the beam 6 which have been subjected to the above-described preparatory work in a precut factory are transported to a construction site. At this time, since the bracket 2 of the present embodiment uses a square bar, the protruding amount of the bracket 2 from the column 5 can be greatly reduced. Therefore, when the pillar 5 to which the metal fitting 2 is fixed in the pre-cut factory is transported to the construction site, the pillar 5 can be efficiently loaded on the truck without being bulky, so that the loading efficiency can be improved. In addition, although the receiving metal fitting 2 of this invention has reduced the protrusion amount significantly from the pillar 5, since the receiving metal main body 21 is made from square steel, it can maintain sufficient firm mechanical strength.

施工現場において、立設された柱５に梁６を接合させる際、まず、連結金具３のピン３２が、受け金具２の係止部２４に係止される。この際、ガイド面２４１によって、ピン３２を係止部２４に容易に係止することができる。また、連結金具３が受け金具２に係止されるので、連結ピン４５の後打ち作業を安全に行うことができる。また、連結ピン４５を打ち込む際、本実施形態の受け金具２は、受け金具本体２１が角棒状としてあるので、連結ピン孔２３の内面がガイド面として機能するので、連結ピン４５の先端が向こう側の孔に挿入しにくくなるといった不具合を回避することができる。
また、打ち込まれた連結ピン４５は、折り曲げ部３５によって補強された連結ピン孔３４及び角鋼によって十分な機械的強度を有する受け金具２の連結ピン孔２３に挿入され、連結金具３と受け金具２を強固に接合させるので、梁６と柱５の接合強度を向上させることができる。 At the construction site, when the beam 6 is joined to the upright column 5, first, the pin 32 of the connection fitting 3 is locked to the locking portion 24 of the receiving bracket 2. At this time, the pin 32 can be easily locked to the locking portion 24 by the guide surface 241. Further, since the connecting metal 3 is locked to the receiving metal 2, the post-working operation of the connecting pin 45 can be performed safely. Further, when the connecting pin 45 is driven, the receiving metal fitting 2 of this embodiment has the receiving metal body 21 in the shape of a square bar, so that the inner surface of the connecting pin hole 23 functions as a guide surface, so that the tip of the connecting pin 45 faces away. It is possible to avoid the problem that it is difficult to insert into the side hole.
The driven connection pin 45 is inserted into the connection pin hole 34 reinforced by the bent portion 35 and the connection pin hole 23 of the receiving metal fitting 2 having sufficient mechanical strength by the square steel, and the connection metal fitting 3 and the receiving metal fitting 2 are inserted. Is strongly bonded, so that the bonding strength between the beam 6 and the column 5 can be improved.

このように、本実施形態にかかる建築用接合金具１は、十分な接合強度を維持しつつ、柱５からの受け金具２の突出量を大幅に低減し、積載効率を向上させることができる。また、連結金具３の取付け作業や梁６の接合作業における作業効率をさらに向上させるとともに、廉価な建築用接合金具１を提供することができる。   As described above, the architectural joining bracket 1 according to the present embodiment can significantly reduce the amount of protrusion of the receiving bracket 2 from the pillar 5 and improve the loading efficiency while maintaining sufficient joint strength. In addition, it is possible to further improve the working efficiency in the connecting work of the connecting fitting 3 and the joining work of the beam 6, and to provide an inexpensive construction fitting 1.

＜応用例＞
図７は、本発明の第一実施形態にかかる建築用接合金具の応用例を説明するための要部の概略斜視図を示している。
同図において、建築用接合金具１ａは、第一実施形態と比較して、上下方向の長さを短くしてあり、受け金具２ａが、上部及び下部の二箇所にそれぞれボルト孔２２及び連結ピン孔２３が穿設され、連結金具３ａが、平板部材３１の柱５側の端部であって、かつ、下部の一箇所に連結ピン孔３４が穿設された点が相違する。他の構成要素は第一実施形態とほぼ同様としてある。
したがって、図７において、図１，２，５と同様の構成部分については同一の符号を付して、その詳細な説明を省略する。 <Application example>
FIG. 7: has shown the schematic perspective view of the principal part for demonstrating the application example of the joint fitting for construction concerning 1st embodiment of this invention.
In the figure, the construction fitting 1a is shorter in the vertical direction than the first embodiment, and the receiving fitting 2a has bolt holes 22 and connecting pins at two locations, the upper and lower parts, respectively. The difference is that the hole 23 is drilled, the connecting fitting 3a is the end of the flat plate member 31 on the column 5 side, and the connecting pin hole 34 is drilled at one location below. Other components are substantially the same as those in the first embodiment.
Therefore, in FIG. 7, the same components as those in FIGS. 1, 2, and 5 are denoted by the same reference numerals, and detailed description thereof is omitted.

（受け金具）
受け金具２ａは、上端部に係止部２４が形成され、下端部に係止部２４´が形成されている。また、受け金具本体２１の長手方向の中央位置２０に対して対称となるように（中央位置２０から同じ距離だけ離れた位置に）、受け金具本体２１の上部及び下部の二箇所に連結ピン孔２３を穿設し、かつ、穿設された各連結ピン孔２３から、上方向に同じ距離だけ離して、ボルト孔２２を二箇所に穿設してある。このようにすると、梁背が短い梁６を接合する際、梁６の強度に応じた接合強度を実現することができる。また、受け金具２ａの長手方向の長さが短くなった場合でも、梁６を直交取付けする際、第二の受け金具（図示せず）を長手方向に反転させて柱５に固定することができ、受け金具２ａの共用化を図ることができる。 (Receiver bracket)
The catch 2a has a locking portion 24 at the upper end and a locking portion 24 'at the lower end. In addition, connecting pin holes are formed at two locations on the upper and lower portions of the receiving metal body 21 so as to be symmetric with respect to the central position 20 in the longitudinal direction of the receiving metal body 21 (at the same distance from the central position 20). 23, and the bolt holes 22 are drilled at two locations, spaced apart from each of the drilled connecting pin holes 23 by the same distance in the upward direction. If it does in this way, when joining the beam 6 with a short beam back, joining strength according to the strength of the beam 6 is realizable. Even when the longitudinal length of the metal fitting 2a is shortened, when the beam 6 is mounted orthogonally, the second metal fitting (not shown) can be inverted in the longitudinal direction and fixed to the column 5. It is possible to share the receiving metal fitting 2a.

（連結金具）
連結金具３は、柱５側の端部であって、かつ下部の一箇所に連結ピン孔３４を穿設してあり、ピン３２及び一本の連結ピン４５によって、梁６を柱５に接合させる構成としてある。すなわち、梁背が短い梁６を接合する際、梁６の強度に応じた接合強度を実現することができ、製造原価のコストダウンを図ることができる。 (Connecting bracket)
The connection fitting 3 is an end portion on the column 5 side and has a connection pin hole 34 drilled at a lower portion, and the beam 6 is joined to the column 5 by the pin 32 and one connection pin 45. This is a configuration to be made. That is, when joining the beam 6 having a short beam back, it is possible to realize the joining strength corresponding to the strength of the beam 6 and to reduce the manufacturing cost.

このように、第一実施形態の応用例にかかる建築用接合金具１ａは、接合する木部材の強度に応じて、小型化することができ、製造原価のコストダウンを図ることができる。   Thus, the construction fitting 1a according to the application example of the first embodiment can be reduced in size according to the strength of the wood member to be joined, and the manufacturing cost can be reduced.

［第二実施形態］
図８は、本発明の第二実施形態にかかる建築用接合金具を説明するための要部の概略図であり、（ａ）は端の梁背が低い梁を接合する場合の建築用接合金具の斜視図を、（ｂ）は端の梁背が高い梁を接合する場合の建築用接合金具の斜視図を示している。
同図において、建築用接合金具１ｂ，１ｃは、梁背が異なる梁６（図示せず）をそれぞれの柱５に接合する場合に使用される接合金具としてあり、建築用接合金具１ｂによる、低い梁背の梁６を柱５に接合する接合強度と同じ強さの接合強度で、建築用接合金具１ｃが、高い梁背の梁６を柱５に接合させる点が相違する。他の構成要素は第一実施形態とほぼ同様としてある。
したがって、図８において、図１，２，５と同様の構成部分については同一の符号を付して、その詳細な説明を省略する。 [Second Embodiment]
FIG. 8: is the schematic of the principal part for demonstrating the joint fitting for construction concerning 2nd embodiment of this invention, (a) is the joint fitting for construction in the case of joining a beam with a low end beam (B) has shown the perspective view of the joining bracket for construction in the case of joining a beam with a high end beam.
In the figure, building joints 1b and 1c are joints used when joining beams 6 (not shown) having different beam backs to respective pillars 5, and are low due to the construction joints 1b. The difference is that the building joint fitting 1c joins the high beam-back beam 6 to the column 5 with the same bonding strength as that for bonding the beam-back beam 6 to the column 5. Other components are substantially the same as those in the first embodiment.
Therefore, in FIG. 8, the same components as those in FIGS. 1, 2, and 5 are denoted by the same reference numerals, and detailed description thereof is omitted.

（建築用接合金具１ｂの受け金具）
建築用接合金具１ｂの受け金具２ｂは、第一実施形態と比較して、上下方向の長さを大幅に短くしてあり、上端部にのみ係止部２４が形成されている。また、長手方向のほぼ中央位置に、連結ピン孔２３を穿設し、かつ、穿設された連結ピン孔２３から、上下方向に同じ距離だけ離して、ボルト孔２２を二箇所に穿設し、さらに、下部正面から背面にかけて、釘（図示せず）を打ち込むための釘孔２５を貫設してある。このようにすると、梁背が低い梁６を接合する際、低い梁背の梁６の強度に応じた接合強度を実現することができる。 (Receiving bracket for construction fitting 1b)
As compared with the first embodiment, the receiving metal fitting 2b of the building joining metal fitting 1b has a length in the vertical direction significantly shortened, and a locking portion 24 is formed only at the upper end. Further, a connecting pin hole 23 is formed at a substantially central position in the longitudinal direction, and the bolt hole 22 is formed in two places, spaced apart from the formed connecting pin hole 23 by the same distance in the vertical direction. Further, a nail hole 25 for driving a nail (not shown) is provided from the lower front to the back. If it does in this way, when joining the beam 6 with a low beam back, the joint strength according to the intensity | strength of the beam 6 with a low beam back is realizable.

また、受け金具２ｂは、二箇所にボルト孔２２が穿設してあるので、二本のボルト４１を用いて、柱５に強固に固定することができる。なお、梁６を柱５に対して直交取付けする際は、いずれか一方のボルト孔２２に挿入する一本のボルト４１と釘孔２５に打ち込む釘によって受け金具２ｂを固定させることができる。   Moreover, since the bolt hole 22 is drilled in two places, the receiving metal fitting 2b can be firmly fixed to the column 5 using the two bolts 41. In addition, when the beam 6 is attached orthogonally to the column 5, the receiving metal fitting 2 b can be fixed by a single bolt 41 inserted into one of the bolt holes 22 and a nail driven into the nail hole 25.

（建築用接合金具１ｂの連結金具）
連結金具３ｂは、第二実施形態の連結金具３ａをさらに上下方向に短くした構造としてある。すなわち、平板部材３１ｂの高さをＨ０とし、先端部付近のほぼ中央部に連結ピン孔３４を穿設してある。 (Connecting metal fittings for architectural fittings 1b)
The connecting fitting 3b has a structure in which the connecting fitting 3a of the second embodiment is further shortened in the vertical direction. That is, the height of the plate member 31b and H 0, are bored a connecting pin hole 34 in a substantially central portion in the vicinity of the tip portion.

上記構造とすることにより、建築用接合金具１ｂは、梁背が低い梁６の強度に応じた接合強度で、梁６を柱５に接合させることができる。   By adopting the above-described structure, the building joint 1b can join the beam 6 to the column 5 with a joining strength corresponding to the strength of the beam 6 having a low beam back.

（建築用接合金具１ｃの受け金具）
建築用接合金具１ｃの受け金具２ｂは、建築用接合金具１ｂの受け金具２ｂと全く同じ構造としてある。このようにすると、梁背が高い梁６を接合する場合であっても、柱５に対する接合強度を調節することができる。 (Receiving bracket for construction fitting 1c)
The metal fitting 2b of the building joint 1c has the same structure as the metal fitting 2b of the building joint 1b. In this way, even when the beam 6 having a high beam height is joined, the joining strength with respect to the column 5 can be adjusted.

（建築用接合金具１ｃの連結金具）
連結金具３ｃは、柱５側の構造、すなわち、ピン３２，連結ピン孔３４及び折り曲げ部３５などの構造を、建築用接合金具１ｂの連結金具３ｂとほぼ同様とし、さらに、梁６に取り付けられる後端部側の平板部材３１ｃを、高い梁背に応じて、高さをＨ１（Ｈ１>Ｈ０）とし、平板部材３１の上部及び下部に取付け孔３３を穿設した構成としてある。このようにすると、連結金具３ｃと梁６の取付け強度を、高い梁背に応じた機械的強度を維持することができる。
なお、平板部材３１ｃは、第二の柱５側の下部を面取りしてあり、連結金具３ｃの軽量化を図っている。 (Connecting bracket for architectural fitting 1c)
The connection fitting 3c has the structure on the column 5 side, that is, the structure of the pin 32, the connection pin hole 34, the bent portion 35, etc., is substantially the same as the connection fitting 3b of the construction fitting 1b, and is attached to the beam 6. The flat plate member 31c on the rear end side is configured such that the height is set to H 1 (H 1 > H 0 ) according to a high beam back, and the mounting holes 33 are formed in the upper and lower portions of the flat plate member 31. If it does in this way, the mechanical strength according to the high beam back can be maintained for attachment strength of connecting metal fitting 3c and beam 6.
The flat plate member 31c is chamfered at the lower part on the second pillar 5 side, so that the weight of the connecting fitting 3c is reduced.

このように、本実施形態にかかる建築用接合金具１ｂ，１ｃは、梁背が異なる梁６を柱５に接合する場合に、梁背に応じた梁６と連結金具３ｂ，３ｃの機械的強度を維持しつつ、受け金具２ｂによる接合強度で、梁６を柱５に接合させることができる。
なお、本実施形態の建築用接合金具１ｂは、梁６と連結金具３ｂの取付け強度とほぼ同じ強度で、連結金具３ｂと受け金具２ｂを接合し、建築用接合金具１ｃは、連結金具３ｃと受け金具２ｂを接合する強度より強固な強度で、梁６に連結金具３ｃを取り付けた構成としてあるが、これに限定されるものではない。たとえば、建築用接合金具１ｃの代わりに、建築用接合金具１ａを用いることにより、梁６と連結金具３ａの取付け強度とほぼ同じ強度で、連結金具３ａと受け金具２ａを接合させる構成としてもよい。 As described above, when the beams 6 having different beam backs are bonded to the pillars 5 according to the present embodiment, the joint metal fittings 1b and 1c according to the present embodiment have the mechanical strength of the beam 6 and the connection brackets 3b and 3c according to the beam back. While maintaining the above, the beam 6 can be joined to the column 5 with the joining strength of the receiving metal fitting 2b.
Note that the building joint 1b according to the present embodiment has substantially the same strength as the mounting strength of the beam 6 and the connection fitting 3b, and joins the connection fitting 3b and the receiving fitting 2b. The building connection fitting 1c is connected to the connection fitting 3c. Although the connection metal fitting 3c is attached to the beam 6 with strength stronger than the strength of joining the receiving metal fitting 2b, it is not limited to this. For example, it is good also as a structure which joins the connection metal fitting 3a and the receiving metal fitting 2a with the intensity | strength substantially the same as the attachment intensity | strength of the beam 6 and the connection metal fitting 3a by using the construction metal fitting 1a instead of the construction metal fitting 1c. .

以上、本発明の受け金具，連結金具及び建築用接合金具について、好ましい実施形態を示して説明したが、本発明に係る受け金具，連結金具及び建築用接合金具は、上述した実施形態にのみ限定されるものではなく、本発明の範囲で種々の変更実施が可能であることは言うまでもない。
例えば、上記実施形態の受け金具２は、角棒状の受け金具本体２１を用いた構成としてあるが、この構成に限定されるものではなく、たとえば、四角筒状の受け金具本体２１を用いてもよく、このようにすると、受け金具の小型化及び軽量化を図ることができるとともに、柱５からの突出量を低減することができる。 As mentioned above, although the preferable embodiment was shown and demonstrated about the receiving metal fitting, connecting metal fitting, and construction joining metal fitting of the present invention, the receiving metal fitting, connecting metal fitting, and construction joining metal fitting concerning the present invention are limited only to the above-mentioned embodiment. It goes without saying that various modifications can be made within the scope of the present invention.
For example, the bracket 2 of the above embodiment has a configuration using the square-bar-shaped bracket main body 21, but is not limited to this configuration. For example, the square-tube-shaped bracket main body 21 may be used. If it does in this way, while being able to achieve size reduction and weight reduction of a receiving metal fitting, the protrusion amount from the pillar 5 can be reduced.
