Description

この発明は、たとえば、一般住宅、ユニットハウス、バンガロー、社寺建築、簡易店舗、東屋、物置、倉庫、ガレージなどの建築に用いるのに好適な接合金物に関する。 The present invention relates to a joint metal fitting suitable for use in buildings such as general houses, unit houses, bungalows, shrines and temples, simple stores, eastern stores, storerooms, warehouses, and garages.

上記のような接合金物には、梁受け金物、柱脚金物など様々なものがあるが、これらは軸組を構成する線材同士を接合するのに際して、これらを互いに直に接触した状態で接合するものである。つまり、木造軸組の線材は接合部分において上下方向または水平方向で相互に重なった状態になっている。このような状態で線材が接合されるので、強固な固定状態が得られるものの、線材が腐食したりした場合に、線材を接合部分から全体的に取り替えることができない。 There are various types of joint hardware as described above, such as beam support hardware and column base hardware, but these are joined in a state in which they are in direct contact with each other when joining the wires constituting the shaft assembly. Is. That is, the wire rods of the wooden frame are in a state where they overlap each other in the vertical direction or the horizontal direction at the joint portion. Since the wire is joined in such a state, a strong fixed state can be obtained, but when the wire is corroded, the wire cannot be entirely replaced from the joined portion.

このため、長期間にわたって使用できる建物とするには難点がある。 For this reason, there exists a difficulty in making it a building which can be used over a long period of time.

この点、下記特許文献１のような木造軸組系ユニットハウスが提案されている。このユニットハウスは、ユニット本体の開口部に取り付ける間柱をドリフトピンで固定して、着脱可能にしたものである。
特許第２８５６６２９号公報 In this regard, a wooden frame system unit house as disclosed in Patent Document 1 below has been proposed. This unit house is configured such that a stud that is attached to an opening of a unit main body is fixed with a drift pin to be detachable.
Japanese Patent No. 2856629

しかし、間柱以外の柱と梁などの接合部分は一般的な接合金物を用いて固定されている。このため、間柱については取替えが可能であろうが、その他の部分については取替えができない。 However, joint portions such as columns and beams other than the inter-columns are fixed using a general joint hardware. For this reason, it will be possible to replace the studs, but not the other parts.

また、ドリフトピンによる固定は、梁に一部を挿入したホゾパイプを用いるものであって、間柱と梁との間はホゾパイプと、部材同士の接触で支えられている。このため、特に水平力がかかったときにめり込みなどが発生するおそれがあり、ホゾパイプのみに頼らなければならず、強度の面で難点がある。 In addition, the fixing by the drift pin uses a hozo pipe having a part inserted into the beam, and the space between the stud and the beam is supported by the contact between the hozo pipe and the members. For this reason, there is a possibility that indentation or the like may occur particularly when a horizontal force is applied, and it is necessary to rely only on the hozo pipe, which is difficult in terms of strength.

そこで、この発明は、柱材等の線材の取替えが可能である上に、構造上、十分な強度を得ることができるようにすることを主たる目的とする。 In view of this, the main object of the present invention is to make it possible to replace a wire rod such as a column member and to obtain a sufficient structural strength.

そのための手段は、軸組を構成する線材を接合する建築用の接合金物であって、線材の長さ方向の端面間に挟まれてこれらの線材を接合すべく、上記の端面間に収まる中空の外郭部を有するとともに、該外郭部における線材の端面を接合する部位に接合面が形成され、これら接合面には、線材を接合するための結合具、またはこれを保持する保持部が備えられ、上記外郭部内には、上下方向に延びる支柱部が備えられ、該支柱部が、上記外郭部材内の中央部分に備えられるとともに、上側部材と下側部材で構成され、これらが上下方向に不分離で、かつ水平方向で相対移動可能に連結された建築用の接合金物である。 The means for this is a metal fitting for construction which joins the wire constituting the shaft assembly, and is sandwiched between the end faces in the length direction of the wire so as to join these wires so that the hollow fits between the end faces. A joint surface is formed at a portion where the end faces of the wire rods in the outer shell portion are joined, and these joint surfaces are provided with a coupler for joining the wire rods or a holding portion for holding the joint. The outer shell is provided with a support column extending in the vertical direction. The support column is provided in the central portion of the outer shell member and is composed of an upper member and a lower member. It is a joint metal fitting for construction which is separated and connected so as to be relatively movable in the horizontal direction .

上記外郭部は、線材の端面間に位置して、一つの線材の端面と、他の線材の側面が重なり合わないように、複数本の線材の端面間の位置関係を保持する。使用箇所によって全周が囲繞される場合も、一部が露出する場合もある。外郭部は６面に線材の端面を固定できるようにするほか、２面や３面、４面、５面に線材の端面を固定することも、また、六角堂のような特異な形態の建物を構成することも、さらには、小屋組の棟木と棟束等の接合を行うこともできる。 The said outer part is located between the end surfaces of a wire, and maintains the positional relationship between the end surfaces of a several wire, so that the end surface of one wire and the side surface of another wire may not overlap. Depending on the place of use, the entire circumference may be surrounded, or a part may be exposed. In addition to being able to fix the end face of the wire to 6 sides, it is also possible to fix the end face of the wire to 2 side, 3 side, 4 side, 5 side, etc. In addition, it is possible to join the purlin of the hut and the bunches.

使用にあたっては、外郭部の接合面に線材の端面を接合する。結合具にはボルトなどの適宜の手段が使用でき、この結合具を保持する保持部は、結合具の種類に応じて貫通孔、ねじ孔、フック状の係合構造などで構成される。 In use, the end face of the wire is joined to the joint surface of the outer shell. Appropriate means such as bolts can be used for the coupler, and the holding portion for holding the coupler is constituted by a through hole, a screw hole, a hook-like engagement structure, or the like according to the type of the coupler.

必要な線材が接合されると、接合金物は線材の端面間に収まった状態となり、相互に接合される線材の端面と側面が面接触しない状態となる。そして、支柱部が、上下方向にかかる荷重に耐えるように外郭部を支持して、この状態で線材の結合が行われる。 When a necessary wire is joined, the joint metal is placed between the end faces of the wire, and the end face and the side face of the wire joined together are not in surface contact. And a support | pillar part supports an outline part so that it can bear the load concerning an up-down direction, and a wire is couple | bonded in this state.

なお、外郭部の接合面は、線材の端面を固定可能にするものであって、すべての接合面に対して線材の端面を固定しなければならないわけではなく、一部の接合面が露出する場合には、そのままにしておいたり、目隠しやアジャスタなどの適宜の部材を固定したりすることもできる。 In addition, the joint surface of the outer portion enables the end surface of the wire to be fixed, and the end surface of the wire does not have to be fixed to all the joint surfaces, and a part of the joint surface is exposed. In some cases, it can be left as it is, or an appropriate member such as a blindfold or an adjuster can be fixed.

以上のように、この発明によれば、接合する線材の端面間に外郭部が介在した状態で接合を行うので、柱材等の線材を丸ごと取り替えることができるうえに、取替え作業も容易である。しかも、中空の外郭部の内部には支柱部が備えられているので、十分な強度を得られるとともに、上下に柱材を接合する場合には、支柱部内にボルト等の結合具を通すことで上下の柱の一体性を高めることができる。 As described above, according to the present invention, since the joining is performed in a state in which the outer portion is interposed between the end faces of the wires to be joined, it is possible to replace the wire materials such as the pillars as a whole and to easily perform the replacement work. . In addition, since the column portion is provided inside the hollow outer portion, sufficient strength can be obtained, and when joining column members up and down, a coupling tool such as a bolt can be passed through the column portion. The integrity of the upper and lower pillars can be increased.

柱材等の線材の取替えが可能である上に、構造上、十分な強度を得ることができるように線材を接合するという目的を、線材の長さ方向の端面間に挟まれてこれらの線材を接合すべく、上記の端面間に収まる中空の外郭部を有するとともに、該外郭部における線材の端面を接合する部位に接合面を形成し、これら接合面には、線材を接合するための結合具、またはこれを保持する保持部を備え、上記外郭部内には、上下方向に延びる支柱部を備え、該支柱部が、上記外郭部材内の中央部分に備えられるとともに、上側部材と下側部材で構成され、これらが上下方向に不分離で、かつ水平方向で相対移動可能に連結されるという構成にて実現した。 The wire rods such as pillars can be replaced, and the purpose of joining the wire rods so that sufficient strength can be obtained structurally is sandwiched between the end faces in the length direction of the wire rods. In addition to having a hollow outer portion that fits between the end surfaces, a bonding surface is formed at a portion where the end surfaces of the wire rod in the outer portion are bonded, and these bonding surfaces are bonded to bond the wire. Or a holding portion for holding the same, and a support column portion extending in the vertical direction is provided in the outer shell portion, and the support column portion is provided in a central portion in the outer shell member, and an upper member and a lower member. in the configuration, it is in nondisjunction in the vertical direction and is realized by configuration in the horizontal direction Ru is relatively movably connected.

以下、この発明を実施するための一形態を、図面を用いて説明する。
この発明の建築用の接合金物には、適用される部位に応じて大きく分けると、柱脚部用の接合金物と梁部用の接合金物がある。
以下、順に説明する。 Hereinafter, an embodiment for carrying out the present invention will be described with reference to the drawings.
The joint metal fittings for construction according to the present invention are roughly classified into a joint metal for the column base and a joint metal for the beam, depending on the portion to be applied.
Hereinafter, it demonstrates in order.

（柱脚部用の接合金物）
図１は、柱脚部用の接合金物１１を示す斜視図であり、図２はその分解斜視図、図３はその縦断面図である。 (Joint hardware for column base)
FIG. 1 is a perspective view showing a metal joint 11 for a column base, FIG. 2 is an exploded perspective view thereof, and FIG. 3 is a longitudinal sectional view thereof.

接合金物１１は、上記のように中空の外郭部２１と、外郭部２１内で上下方向に延びる支柱部３１を有する。そして、外郭部２１における線材６１（柱材、土台）の端面を接合する部位に接合面２２が形成されている。接合面２２は、上端面と外周の４箇所に形成される。上端面の接合面２２部分には、線材６１（柱材）を接合するための結合具としてのボルト３２が保持され、他の外周の接合面には、結合具としてのボルト４１（図４参照）を保持する保持部としての保持孔２２ａが形成され、図４に示したようにボルト４１，３２が螺合するコア５１（図４参照）を介して、接合面２２に線材６１の端面６１ａが接合される。 As described above, the metal joint 11 includes the hollow outer portion 21 and the column portion 31 extending in the vertical direction within the outer portion 21. And the joining surface 22 is formed in the site | part which joins the end surface of the wire 61 (column material, a base) in the outer part 21. FIG. The joint surface 22 is formed at four locations on the upper end surface and the outer periphery. A bolt 32 as a coupling tool for joining the wire 61 (column material) is held on the joining surface 22 portion of the upper end surface, and a bolt 41 (see FIG. 4) as a coupling tool is provided on the other outer joint surface. ) Is formed, and the end surface 61a of the wire rod 61 is joined to the joining surface 22 via the core 51 (see FIG. 4) to which the bolts 41 and 32 are screwed as shown in FIG. Are joined.

外郭部２１は、弓形をなす４個の屈曲板２５と、これらの上下両端部を結合する上板２６および下板２７からなる。屈曲板２５は、短冊状の金属板をプレス成形してなるもので、長さ方向の中間部に略正方形状の上記接合面２２を有し、長さ方向におけるこれらの両側に、図１に示した如く組み立てたときに面取り状になる傾斜面２５ａが連設されている。そして傾斜面２５ａの先端部には、接合面２５ａに対して直角の方向に延びる結合面２５ｂが延設される。この結合面２５ｂの先端には接合金物１１の上端面部分に保持される上記ボルト３２等をぬすむ切欠２５ｃが形成されている。また結合面２５ｂは、組み立てに際して用いるねじ部材２８を挿通する挿通孔２５ｄを有する。挿通孔２５ｄは、上記ねじ部材２８としての皿ねじの頭部を収められるように略逆円錐状に形成されている。なお、ねじ部材２８の長さは、屈曲板２５と上板２６または下板２７の厚さを合わせた長さに設定され、螺合時にねじ部材２８が突出しないようにされている。 The outer portion 21 includes four bent plates 25 each having an arcuate shape, and an upper plate 26 and a lower plate 27 that connect the upper and lower ends thereof. The bent plate 25 is formed by press-molding a strip-shaped metal plate. The bent plate 25 has the substantially square-shaped joining surface 22 in the middle in the length direction, and on both sides of the length direction in FIG. An inclined surface 25a that is chamfered when assembled as shown is continuously provided. A coupling surface 25b extending in a direction perpendicular to the bonding surface 25a is provided at the tip of the inclined surface 25a. A notch 25c is formed at the front end of the coupling surface 25b so as to cut the bolt 32 and the like held on the upper end surface portion of the metal joint 11. The coupling surface 25b has an insertion hole 25d through which the screw member 28 used for assembly is inserted. The insertion hole 25d is formed in a substantially inverted conical shape so that the head of a countersunk screw as the screw member 28 can be accommodated. The length of the screw member 28 is set to the total length of the bending plate 25 and the thickness of the upper plate 26 or the lower plate 27 so that the screw member 28 does not protrude when screwed.

上記上板２６は、略正方形をなす金属板で形成され、中央には上記のボルト３２が通る貫通孔２６ａが形成されるとともに、外周部に、上記屈曲板２５の結合面２５ｂの挿通孔２５ｄと対応する位置にねじ孔２６ｂが形成されている。また、外周縁の端面２６ｃは、上記傾斜面２５ａの傾斜に対応するように傾斜している。 The upper plate 26 is formed of a substantially square metal plate. A through hole 26a through which the bolt 32 is passed is formed at the center, and an insertion hole 25d of the coupling surface 25b of the bent plate 25 is formed on the outer periphery. A screw hole 26b is formed at a position corresponding to. Moreover, the end surface 26c of the outer peripheral edge is inclined so as to correspond to the inclination of the inclined surface 25a.

この上板２６は、各屈曲板２５の結合面２５ｂの下側において、各屈曲板２５を一体に結合する。 The upper plate 26 integrally couples the bent plates 25 below the coupling surface 25b of the bent plates 25.

上記下板２７は、略正方形をなす金属板で形成され、中央にはアンカーボルト７１（図６参照）等を通すための貫通孔２７ａが形成されるとともに、外周部に、上記屈曲板２５の結合面２５ｂの挿通孔２５ｄと対応する位置にねじ孔２７ｂが形成されている。このねじ孔２７ｂのほかに、四隅には、アジャスタ２９を螺合可能に保持するためのねじ孔２７ｃも形成されている。さらに、外周縁のうち４辺の中央部部分の端面２７ｄは、上記の傾斜面２５ａの傾斜に対応するように傾斜している。なお、上記の貫通孔２７ａは、アンカーボルト７１等の太さよりも大きく形成されている。このため、上記屈曲板２５の下端の結合面２５ｂに形成する切欠２５ｃも、上端の結合面２５ｂの切欠２５ｃよりも大きく形成されている。 The lower plate 27 is formed of a substantially square metal plate, and a through hole 27a for passing an anchor bolt 71 (see FIG. 6) or the like is formed at the center. A screw hole 27b is formed at a position corresponding to the insertion hole 25d of the coupling surface 25b. In addition to the screw holes 27b, screw holes 27c for holding the adjusters 29 in a screwable manner are formed at the four corners. Furthermore, the end surface 27d of the central part of the four sides of the outer peripheral edge is inclined so as to correspond to the inclination of the inclined surface 25a. In addition, said through-hole 27a is formed larger than the thickness of anchor bolt 71 grade | etc.,. For this reason, the notch 25c formed in the coupling surface 25b at the lower end of the bent plate 25 is also formed larger than the notch 25c in the coupling surface 25b at the upper end.

上記支柱部３１は、全体として円柱状に形成され、円柱状をなす上側部材３５と下側部材３６で構成されている。上側部材３５と下側部材３６は、上下方向に不分離でありながらも、水平方向で相対移動可能に連結されている。 The column portion 31 is formed in a columnar shape as a whole, and is composed of a columnar upper member 35 and a lower member 36. The upper member 35 and the lower member 36 are coupled so as to be relatively movable in the horizontal direction while being not separated in the vertical direction.

すなわち、図３に示したように、上側部材３５は中空の円柱状に形成され、上端には、ねじ部を上方に向けた状態で上記のボルト３２が一体に保持されている。一体化には溶接等の適宜の接合手段が用いられる。 That is, as shown in FIG. 3, the upper member 35 is formed in a hollow cylindrical shape, and the bolt 32 is integrally held at the upper end with the threaded portion facing upward. For the integration, an appropriate joining means such as welding is used.

また、上側部材３５の下端には、抜け止めのための抜け止め部材３７が一体に固定されている。抜け止め部材３７は、上側部材３５の下端部に固定される固定部３７ａと、この下の小径部３７ｂと、小径部３７ｂの下で小径部３７ｂより大径の大径部３７ｃとを有する。図面においては便宜上、短円柱状に描いたが、上記の大径部３７ｃは、カシメて形成することも、ナットやボルトの頭部で構成することもできる。 In addition, a retaining member 37 for retaining is integrally fixed to the lower end of the upper member 35. The retaining member 37 has a fixed portion 37a fixed to the lower end portion of the upper member 35, a small-diameter portion 37b below this, and a large-diameter portion 37c having a diameter larger than the small-diameter portion 37b below the small-diameter portion 37b. In the drawing, for the sake of convenience, it is drawn in the shape of a short cylinder. However, the large diameter portion 37c can be formed by caulking, or can be constituted by the heads of nuts and bolts.

下側部材３６は、有底円筒状に形成され、上端には蓋部材３８が固定されている。この蓋部材３８の中央に、上記抜け止め部材３７の大径部３７ｃよりも小径で、小径部３７ｂよりも大径の穴部３８ａが形成されている。この穴部３８ａは、下板２７の貫通孔２７ａと同径である。 The lower member 36 is formed in a bottomed cylindrical shape, and a lid member 38 is fixed to the upper end. A hole 38 a having a smaller diameter than the large diameter portion 37 c of the retaining member 37 and a larger diameter than the small diameter portion 37 b is formed in the center of the lid member 38. The hole 38 a has the same diameter as the through hole 27 a of the lower plate 27.

下側部材３６の底面には、上記アンカーボルト７１（図６参照）等を通すため、これらに対応する径の貫通孔３６ａが形成され、貫通孔３６ａの上側にはナット３６ｂが保持されている。ナット３６ｂを用いずに、貫通孔３６ａに直接ねじを切るもよい。 In order to pass the anchor bolt 71 (see FIG. 6) and the like on the bottom surface of the lower member 36, a through hole 36a having a diameter corresponding thereto is formed, and a nut 36b is held above the through hole 36a. . You may cut a screw | thread directly to the through-hole 36a, without using the nut 36b.

また、これら上側部材３５と下側部材３６には、接合作業に際して回転力を入力するために、棒状の治具（図示せず）を挿入する係止孔３９が形成されている。図示のような円形の孔のほか、治具の形態に応じて適宜の形状にすることができる。 The upper member 35 and the lower member 36 are formed with a locking hole 39 into which a rod-shaped jig (not shown) is inserted in order to input a rotational force during the joining operation. In addition to the circular hole as shown in the figure, it can be formed in an appropriate shape according to the form of the jig.

このように構成された接合金物１１では、接合金物１１を所定位置に固定した後、図４に示したように、外郭部２１の外周部に存在する接合面２２に結合具としてのボルト４１を保持するとともに、線材６１としての土台６２の端面６１ａを接合し、その後、図５に示したように外郭部２１の上端の接合面２２部分に保持したボルト３２を用いて線材６１としての柱材６３の端面６１ａを接合する。 In the joining hardware 11 configured as described above, after fixing the joining hardware 11 in a predetermined position, as shown in FIG. 4, the bolt 41 as a coupling tool is attached to the joining surface 22 existing on the outer peripheral portion of the outer shell portion 21. While holding, it joins the end surface 61a of the base 62 as the wire rod 61, and then, as shown in FIG. 5, the pillar material as the wire rod 61 using the bolt 32 held on the joint surface 22 portion at the upper end of the outer shell portion 21. 63 end faces 61a are joined.

ボルト３２，４１と線材６１との間には、金属製のコア材５１とドリフトピン５５を介在させる。
コア材５１は、長さ方向の一方に雌ねじ５１ａを有し、他方に、ドリフトピン５５を挿通する挿通孔５１ｂが形成された構造である。 A metal core material 51 and a drift pin 55 are interposed between the bolts 32 and 41 and the wire rod 61.
The core material 51 has a structure in which a female screw 51a is formed on one side in the length direction and an insertion hole 51b through which the drift pin 55 is inserted is formed on the other side.

具体的には、図６に示したようにアンカーボルト７１に対して外郭部２１の下端部を挿嵌し、支柱部３１の下側部を回転しながら、アジャスタ２９で水平を出し、高さを調整して、アンカーボルト７１に対する固定を行う。下側部材３６の回転は、外郭部２１の接合面２２間の透き間を利用して行える。 Specifically, as shown in FIG. 6, the lower end portion of the outer shell portion 21 is inserted into the anchor bolt 71, and the lower portion of the column portion 31 is rotated, and the adjuster 29 is leveled to raise the height. Is fixed to the anchor bolt 71. The lower member 36 can be rotated using the gap between the joint surfaces 22 of the outer shell 21.

このとき、外郭部２１の下端面の貫通孔２７ａと、支柱部３１の下側部材３６における蓋部材３８の穴部３８ａは、アンカーボルト７１の径よりも大径に形成されているので、アンカーボルト７１の位置ずれを吸収し、柱材６３を適切な位置に建て込むことができる。 At this time, the through hole 27a on the lower end surface of the outer shell portion 21 and the hole portion 38a of the lid member 38 in the lower member 36 of the column portion 31 are formed to have a larger diameter than the diameter of the anchor bolt 71. The displacement of the bolt 71 can be absorbed, and the pillar material 63 can be built in an appropriate position.

つぎに、土台６２を接合する４個の接合面２２にボルト４１を保持し、このボルト４１に対してコア材５１とドリフトピン５５を用いて、図７に示したように四方に土台６２を固定する。 Next, the bolts 41 are held on the four joint surfaces 22 to which the base 62 is joined, and the base material 62 and the drift pins 55 are used for the bolts 41, as shown in FIG. Fix it.

そして、必要な土台６２を接合した後、上端から上に延びるボルト３２にコア材５１を螺合し、このコア材５１に柱材６３を挿入して、柱材６３の端面６１ａを接合面２２に面接触させて、ドリフトピン５５で固定する（図５参照）。 After the necessary base 62 is joined, the core material 51 is screwed into the bolt 32 extending upward from the upper end, the pillar material 63 is inserted into the core material 51, and the end surface 61 a of the pillar material 63 is joined to the joining surface 22. And are fixed by drift pins 55 (see FIG. 5).

接合金物１１が上記のように構成されて柱脚部の接合に用いられると、接合される４本の土台６２の端面６１ａと、１本の柱材６３の端面６１ａは、接合金物１１の外郭部２１を構成する接合面２２に突き当たった状態で固定される。このとき、土台６２と柱材６３の側面と端面６１ａが面接触する、噛み合うような接合状態とはならず、端面６１ａの縁が当接し合うような接合となって、端面６１ａで囲まれる空間内に接合金物１１が埋没する状態となる。このため、土台６２や柱材６３の交換が容易に行え、長期間にわたって使用できる優良な建築物を得ることができる。 When the metal joint 11 is configured as described above and is used for joining the column bases, the end surfaces 61a of the four bases 62 to be joined and the end surfaces 61a of the single pillar member 63 are the outlines of the joint hardware 11. It fixes in the state which contact | abutted to the joint surface 22 which comprises the part 21. FIG. At this time, the side surface of the base 62 and the column member 63 and the end surface 61a are in surface contact with each other, and are not joined to each other, but are joined so that the edges of the end surface 61a come into contact with each other. The joint hardware 11 is buried inside. For this reason, the base 62 and the pillar material 63 can be easily replaced, and an excellent building that can be used over a long period of time can be obtained.

しかも接合は、ボルト３２，４１とコア材５１とドリフトピン５５とによる簡素な構造で行え、接合作業は簡単である。そのうえ、土台６２や柱材６３に対する加工も少なくて済み、欠損をなくすことができる。このため、面同士が密に接した強固な固定状態が得られる。 Moreover, the joining can be performed with a simple structure using the bolts 32 and 41, the core material 51, and the drift pin 55, and the joining work is simple. In addition, the processing on the base 62 and the pillar material 63 can be reduced, and defects can be eliminated. For this reason, the firm fixed state which surfaces contact | connected closely is obtained.

また、外郭部２１の内部には、円柱状をなす支柱部３１が保持されているので、縦横の荷重に耐え得る堅固な構造にでき、頑丈な建築物を得ることができる。 Moreover, since the column-shaped support | pillar part 31 is hold | maintained inside the outer part 21, it can be set as the firm structure which can bear the load of length and width, and a sturdy building can be obtained.

さらに、外郭部２１は複数の部材を組み立てて構成される。このため、接合金物の管理や輸送に際してコンパクト化を図ることができ、コストの低減や取り扱い性の向上を図ることができる。 Further, the outer portion 21 is configured by assembling a plurality of members. For this reason, it is possible to reduce the size when managing and transporting the joint hardware, and it is possible to reduce the cost and improve the handleability.

しかも、外郭部２１を構成する屈曲板２５は弓形をなし、その長さ方向の中心に接合面２２が形成されているので、過度の応力集中を回避でき、左右方向での圧縮や引っ張りに強く、堅固な建築物を得ることができる。 In addition, the bent plate 25 constituting the outer portion 21 has an arcuate shape, and the joining surface 22 is formed at the center in the length direction, so that excessive stress concentration can be avoided and strong against compression and tension in the left-right direction. You can get a solid building.

また、外郭部２１は、弓形をなす４個の屈曲板２５を組み立てて形成されるので、線材６１の端面６１ａ間に埋没する形状でありながらも、材料を少なくすることができ、コストの低減や軽量化にも資する。 Further, since the outer shell portion 21 is formed by assembling four bow-shaped bent plates 25, the material can be reduced and the cost can be reduced even though the outer shell portion 21 is embedded in the end surface 61a of the wire rod 61. It also contributes to weight reduction.

さらに、各部材は、梁部用の接合金物１１等に流用することもできるので、この点からもコストの低減等に貢献できる。 Furthermore, since each member can also be diverted to the joint 11 for the beam portion, it is possible to contribute to cost reduction and the like from this point.

図８に示したように土台６２を三方に接合する部分では、外郭部２１のうちの１個の接合面２２が露出することになるが、この場合には、露出する接合面２２の外側を隠蔽するとよい。図８（ａ）に示したように、土台６２の端面６１ａと同一形状の板材８１を接合するほか、図８（ｂ）に示したように、逆Ｔ字形をなす周知の補強金物８２の接合で隠蔽することもできる。補強金物８２を用いれば、この補強金物８２によっても土台６２と柱材６３の接合ができ、より強固な固定状態を得られる。また、板材８１や補強金物８２の固定に際して、必要であれば、図８（ａ）に示したように、接合面２２等に固定に適した取り付け孔８３，８１ａなどの加工を施しておく。なお、接合面２２は、図８（ａ）に示したように、土台６２の表面位置よりも板材８１の厚みに対応するぶん内側に後退させておくと、板材８１の表面を土台６２の表面と面一にできるのでよい。 As shown in FIG. 8, at the portion where the base 62 is joined in three directions, one joining surface 22 of the outer shell portion 21 is exposed. In this case, the outside of the exposed joining surface 22 is exposed. It is good to hide. As shown in FIG. 8 (a), a plate 81 having the same shape as the end surface 61a of the base 62 is joined. In addition, as shown in FIG. 8 (b), a well-known reinforcing metal piece 82 having an inverted T-shape is joined. You can also hide it. If the reinforcement hardware 82 is used, the base 62 and the pillar material 63 can be joined also by this reinforcement hardware 82, and a stronger fixed state can be obtained. Further, when fixing the plate member 81 and the reinforcing hardware 82, if necessary, as shown in FIG. 8 (a), processing such as attachment holes 83 and 81a suitable for fixing is performed on the joint surface 22 and the like. As shown in FIG. 8A, when the joining surface 22 is moved back to the inside corresponding to the thickness of the plate 81 from the surface position of the base 62, the surface of the plate 81 is the surface of the base 62. It is good because it can be leveled with.

図９、図１０、図１１、図１２は、他の例に係る柱脚部用の接合金物１１の斜視図と、使用状態の縦断面図である。以下、これらの接合金物１１について説明するが、この説明において、先の構成と同一または同等の部位については、同一の符号を付してその詳しい説明を省略する。 FIG. 9, FIG. 10, FIG. 11, and FIG. 12 are a perspective view and a longitudinal sectional view of a use state of a metal fitting 11 for a column base according to another example. Hereinafter, although these joint hardware 11 is demonstrated, in this description, about the site | part which is the same as that of the previous structure, or the equivalent, the same code | symbol is attached | subjected and the detailed description is abbreviate | omitted.

図９は、図１に示した接合金物１１を、アンカーボルトを利用せずに設置した使用状態を示している。すなわち、支柱部３１に内蔵したナット３６ｂに対しては、外郭部２１と支柱部３１を結合一体化するためのボルト７２を下から螺合している。 FIG. 9 shows a use state in which the metal joint 11 shown in FIG. 1 is installed without using anchor bolts. That is, a bolt 72 for connecting and integrating the outer shell portion 21 and the column portion 31 from below is screwed to the nut 36 b built in the column portion 31.

図１０は、他の例に係る接合金物１１の斜視図であり、支柱部３１が円柱状ではなく、六角柱状に形成されている。このため上記のような係止孔なしでも回転して接合作業を行うことができる。 FIG. 10 is a perspective view of a metal joint 11 according to another example, in which the support column 31 is formed in a hexagonal column shape instead of a column shape. For this reason, even if there is no above-mentioned locking hole, it can rotate and can perform joining work.

図１１は、他の例に係る接合金物１１の斜視図であり、図１２はその使用状態の縦断面図である。この接合金物１１は、アンカーボルトなしで設置するも、アンカーボルトに固定して設置するも、いずれも可能なように構成されている。 FIG. 11 is a perspective view of a metal joint 11 according to another example, and FIG. 12 is a longitudinal sectional view of the usage state. The metal joint 11 can be installed without an anchor bolt or can be fixed to the anchor bolt.

上板２６の貫通孔２６ａも、下板２７の貫通孔２７ａも、ボルト７３又はアンカーボルトが通る大きさに設定されている。 Both the through hole 26a of the upper plate 26 and the through hole 27a of the lower plate 27 are set to a size through which the bolt 73 or the anchor bolt passes.

また、支柱部３１は円筒状に形成され、支柱部３１の上下両端が上板２６と下板２７に対して溶接等により固定される。あるいは、位置ずれを防止できればよいので、凹凸で着脱可能に係合するようにしてもよい。 The support column 31 is formed in a cylindrical shape, and the upper and lower ends of the support column 31 are fixed to the upper plate 26 and the lower plate 27 by welding or the like. Alternatively, as long as it is possible to prevent displacement, it may be detachably engaged with unevenness.

このように構成された接合金物１１では、ボルト７３又はアンカーボルトに外郭部２１の貫通孔２７ａ，２６ａを挿嵌し、上端から突出したボルト７３又はアンカーボルトの先端部にコア材５１を螺合し、このコア材５１とドリフトピン５５を用いて柱材６２の接合を行う。 In the metal joint 11 configured as described above, the through holes 27a and 26a of the outer shell portion 21 are inserted into the bolt 73 or the anchor bolt, and the core material 51 is screwed into the bolt 73 or the tip of the anchor bolt protruding from the upper end. The column material 62 is joined using the core material 51 and the drift pin 55.

ボルト７３又はアンカーボルトによって外郭部２１と支柱部３１が一体となり、この状態で土台６２と柱材６３の接合が行えるので、強固な接合状態が得られる。 The outer shell portion 21 and the column portion 31 are integrated by the bolt 73 or the anchor bolt, and the base 62 and the column member 63 can be joined in this state, so that a strong joined state is obtained.

（梁部用の接合金物）
図１３は、梁部用の接合金物１１の斜視図、図１４はその分解斜視図、図１５はその縦断面図である。これらの図に示すように、線材６１の端面６１ａを接合する接合面２２が上端と下端と周囲４箇所の合計６面に形成されている。 (Joint hardware for beams)
13 is a perspective view of the joint 11 for the beam portion, FIG. 14 is an exploded perspective view thereof, and FIG. 15 is a longitudinal sectional view thereof. As shown in these drawings, the joining surfaces 22 for joining the end surfaces 61a of the wire 61 are formed on a total of six surfaces including an upper end, a lower end, and four surroundings.

基本的には図１〜図３に示した接合金物１１と同様に形成されるが、上板２６と下板２７と、支柱部３１で相違する。以下の説明において、先の説明と同一または同等の部位については同一の符号を付してその詳しい説明を省略する。 Although it is basically formed in the same manner as the metal joint 11 shown in FIGS. 1 to 3, the upper plate 26, the lower plate 27, and the column portion 31 are different. In the following description, parts that are the same as or equivalent to those described above are assigned the same reference numerals, and detailed descriptions thereof are omitted.

上板２６の下面には、ねじ部を上板２６の上に突出した状態でボルト３２が固定される。 Bolts 32 are fixed to the lower surface of the upper plate 26 with the threaded portion protruding above the upper plate 26.

下板２７にはアジャスタが不要である関係上、下板２７は図２に示した上板２６と同一形状に形成されている。 Since the lower plate 27 does not require an adjuster, the lower plate 27 is formed in the same shape as the upper plate 26 shown in FIG.

支柱部３１は、有底円筒状をなす１個の部材で構成され、底には、下方に突出する結合具としてのボルト３３の頭部が保持されている。この支柱部３１の内径は、上板２６に固定したボルト３２の頭部よりも大径に形成され、支柱部３１が回転するようにされている。 The support column 31 is formed of a single member having a bottomed cylindrical shape, and the bottom of the head of a bolt 33 as a coupling tool protruding downward is held on the bottom. The inner diameter of the support column 31 is formed larger than the head of the bolt 32 fixed to the upper plate 26 so that the support column 31 rotates.

このように構成した接合金物１１では、支柱部３１に下板２７と上板２６を組みつけてから各屈曲板２５を組みあわせてねじ部材２８による固定を行う。 In the metal joint 11 configured as described above, the lower plate 27 and the upper plate 26 are assembled to the support 31, and then the bent plates 25 are combined to be fixed by the screw members 28.

そして、使用にあっては、図１６に示したように、下のボルト３３に対してコア材５１を固定したのち柱材６３に対して固定する。またはコア材５１を柱材６３に収容したのちコア材５１に対して螺合して固定する。 In use, as shown in FIG. 16, the core material 51 is fixed to the lower bolt 33 and then fixed to the column material 63. Alternatively, after the core material 51 is accommodated in the pillar material 63, the core material 51 is screwed and fixed to the core material 51.

つぎに、図１７、図１８に示したように、接合面２２にボルト４１を保持して、線材６１としての梁材６４を固定し、その後、柱材６３を固定する。 Next, as shown in FIGS. 17 and 18, the bolt 41 is held on the joint surface 22 to fix the beam member 64 as the wire member 61, and then the column member 63 is fixed.

接合金物１１が上記のように構成されて梁部の接合に用いられると、接合される２本の柱材６３の端面６１ａと、４本の梁材６４の端面６１ａは、接合金物１１の外郭部２１を構成する接合面２２に突き当たった状態で固定される。このとき、柱材６３と梁材６４の側面と端面６１ａとが面接触する、噛み合うような接合状態とはならず、端面６１ａの縁が当接するような接合となって、端面６１ａで囲まれる空間内に接合金物１１が埋没する状態となる。このため、柱材６３や梁材６４の交換が容易に行え、長期間にわたって使用できる優良な建築物を得ることができる。 When the metal joint 11 is configured as described above and is used for joining the beam portion, the end surfaces 61a of the two column members 63 to be joined and the end surfaces 61a of the four beam members 64 are surrounded by the outline of the joint hardware 11. It fixes in the state which contact | abutted to the joint surface 22 which comprises the part 21. FIG. At this time, the side surfaces of the column member 63 and the beam member 64 and the end surface 61a are brought into surface contact with each other and are not engaged with each other, but are joined so that the edges of the end surface 61a come into contact with each other, and are surrounded by the end surface 61a. The joint hardware 11 is buried in the space. For this reason, it is possible to easily replace the column member 63 and the beam member 64, and to obtain an excellent building that can be used for a long period of time.

しかも、接合金物１１と柱材６３および梁材６４の接合は、ボルト３２，３３とコア材５１とドリフトピン５５とによる簡素な構造で接合でき、作業は簡単である。そのうえ、柱材６２や梁材６４に対する加工も少なくて済み、欠損をなくすことができる。このため、面同士が密に接した強固な固定状態が得られる。 In addition, the joining of the joint hardware 11 and the column member 63 and the beam member 64 can be performed with a simple structure using the bolts 32 and 33, the core member 51, and the drift pin 55, and the operation is simple. In addition, the processing for the column member 62 and the beam member 64 can be reduced, and defects can be eliminated. For this reason, the firm fixed state which surfaces contact | connected closely is obtained.

また、外郭部２１の内部には支柱部材３１が保持されているので、縦横の荷重に耐え得る堅固な構造にでき、頑丈な建築物を得ることができる。 Moreover, since the support | pillar member 31 is hold | maintained inside the outer part 21, it can be set as the firm structure which can endure the load of length and width, and a sturdy building can be obtained.

さらに、外郭部２１は複数の部材を組み立てて構成される。このため、接合金物１１の管理や輸送に際してコンパクト化を図ることができ、コストの低減や取り扱い性の向上を図ることができる。 Further, the outer portion 21 is configured by assembling a plurality of members. For this reason, it is possible to reduce the size of the joint hardware 11 when managing and transporting it, and it is possible to reduce costs and improve handling.

しかも、外郭部２１を構成する屈曲板２５は弓形をなし、その長さ方向の中心に接合面２２が形成されているので、過度の応力集中を回避でき、左右方向での圧縮や引っ張りに強い。このため、横からの力に対しても堅固な建築物を得ることができる。 In addition, the bent plate 25 constituting the outer portion 21 has an arcuate shape, and since the joining surface 22 is formed at the center in the length direction, excessive stress concentration can be avoided, and it is strong against compression and tension in the left-right direction. . For this reason, a firm building can be obtained even from the side force.

図１９は、４個の接合面２２のうちの１個の接合面２２に対する梁材６４の固定構造の他の例を示し、図示例のような梁受け金物８５を利用する。この場合、接合面２２の保持孔２２ａには、梁受け金物８５を固定するためのボルト８６が螺合する雌ねじが形成される。このようにすると、ボルト４１とコア材５１を用いる場合よりも、四方に接続する梁材６４のうちの最後の１本の梁材６４の接合が簡単に行え、取り外しも容易である。 FIG. 19 shows another example of the fixing structure of the beam member 64 to one of the four bonding surfaces 22, and uses a beam receiving object 85 as shown in the drawing. In this case, a female screw into which a bolt 86 for fixing the beam receiver 85 is screwed is formed in the holding hole 22a of the joint surface 22. In this way, the last beam member 64 of the beam members 64 connected in all directions can be easily joined and removed, as compared with the case where the bolt 41 and the core member 51 are used.

この他に、例えば図２０に示したように、１個の接合面２２の保持部としての保持孔２２ａを、上側の方が大径となる逆雪だるま形状に形成し、梁材６４の端面６１ａから接合面２２の厚さ分突出させた係合部材８７を引っ掛けるようにしてもよい。 In addition to this, for example, as shown in FIG. 20, a holding hole 22a as a holding portion of one joint surface 22 is formed in a reverse snowman shape having a larger diameter on the upper side, and an end face 61a of the beam member 64 is formed. Alternatively, the engaging member 87 that protrudes by the thickness of the joining surface 22 may be hooked.

図２１は、梁部用の接合金物１１が１階建ての建築物に用いられる場合や、複数階建ての建築物の上端部分に用いられる場合の例を示し、上端の接合面２２部分に突出しているボルト３２に、吊り下げ部材８８を取り付ける例を示している。吊り下げ部材８８は、上端部に環状部８８ａを設け、その下にボルト３２が螺合する螺合部８８ｂを有している。このような吊り下げ部材８８を取り付けると、建築物がユニットハウスの場合に行われる吊り下げに便利である。 FIG. 21 shows an example in which the joint 11 for the beam is used for a one-story building or used for the upper end part of a multi-story building, and protrudes from the joint surface 22 part at the upper end. The example which attaches the suspending member 88 to the volt | bolt 32 currently shown is shown. The suspension member 88 has an annular portion 88a at the upper end portion, and has a screwing portion 88b to which the bolt 32 is screwed. When such a suspension member 88 is attached, it is convenient for suspension performed when the building is a unit house.

なお、上端の接合面２２部分にボトル３２がなくとも、吊り下げ部材（図示せず）に形成された雄ねじを螺合するねじ孔が形成されていれば、吊り下げ部材の取り付けは可能である。 In addition, even if there is no bottle 32 in the joining surface 22 part of an upper end, if the screw hole which screws in the male screw formed in the suspension member (not shown) is formed, attachment of a suspension member is possible. .

図２２は、梁部用の接合金物１１で特殊な梁パネル６５を接合する例を示している。図中、６５ａは線材２１としての上部梁材、６５ｂは線材としての下部梁材、６５ｃは束部材、６５ｄは耐力パネルである。接合金物１１は、図１３に示したものと同一である。 FIG. 22 shows an example in which a special beam panel 65 is joined by a joint 11 for a beam part. In the figure, 65a is an upper beam material as the wire 21, 65b is a lower beam material as a wire, 65c is a bundle member, and 65d is a load-bearing panel. The metal joint 11 is the same as that shown in FIG.

すなわち、柱材６３の上端に第１の接合金物１１を接合した後、この第１の接合金物１１の上に線材としての補助柱材６３ａを接合する。補助柱材６３ａの上には、第２の接合金物１１を接合してから、各接合金物１１，１１の接合面２２にボルト４１とコア材５１を用いて梁パネル６５の上部梁材６５ａと下部梁材６５ｂの端面を接合する。 That is, after joining the first joining hardware 11 to the upper end of the pillar material 63, the auxiliary pillar material 63 a as a wire material is joined on the first joining hardware 11. After the second metal fitting 11 is joined on the auxiliary pillar 63a, the upper beam material 65a of the beam panel 65 is connected to the joining surface 22 of each joint metal 11, 11 using the bolt 41 and the core material 51. The end surfaces of the lower beam member 65b are joined.

図２３は、他の例に係る接合金物１１の斜視図であり、支柱部３１が円柱状ではなく、六角柱状に形成されている。このため上記のような係止孔なしでも回転して接合作業を行うことができる。 FIG. 23 is a perspective view of a metal joint 11 according to another example, in which the support column 31 is formed in a hexagonal column shape instead of a column shape. For this reason, even if there is no above-mentioned locking hole, it can rotate and can perform joining work.

図２４は、他の例に係る接合金物１１の縦断面図であり、外郭部２１内の支柱部内に、外郭部２１の高さよりも長くねじ部分だけの１本のボルト７４を一体に保持する構造を示している。 FIG. 24 is a vertical cross-sectional view of a metal joint 11 according to another example, and a single bolt 74 that is longer than the height of the outer portion 21 and has only a screw portion is integrally held in a support column in the outer portion 21. The structure is shown.

すなわち、外郭部２１の上板２６と下板２７の貫通孔２６ａ，２７ａは、ボルト７４を挿通可能な大きさに設定され、支柱部３１は１本の中空の円筒状に形成されている。そして、支柱部３１の上下両端の中心部には、ボルトを螺合するためのねじ孔３４が形成されている。 That is, the through holes 26a and 27a of the upper plate 26 and the lower plate 27 of the outer portion 21 are set to a size that allows the bolt 74 to be inserted, and the support column portion 31 is formed in a single hollow cylindrical shape. And the screw hole 34 for screwing a volt | bolt is formed in the center part of the up-and-down both ends of the support | pillar part 31. As shown in FIG.

このような構成の接合金物１１では、支柱部３１を内部に入れた状態で上板２６および下板２７と４個の屈曲板２５をねじ部材２８で固定するとともに、使用時にボルト７４を支柱部３１の上下両端のねじ孔３４に螺合する。そして、図２５に示したように、ボルト７４の両端部にコア材５１が螺合された状態となるように、柱材６３や梁材６４の接合を行う。 In the metal joint 11 having such a configuration, the upper plate 26 and the lower plate 27 and the four bent plates 25 are fixed with the screw members 28 in a state where the column portion 31 is inserted, and the bolts 74 are fixed to the column portion at the time of use. The screw holes 34 at both upper and lower ends of 31 are screwed together. Then, as shown in FIG. 25, the column material 63 and the beam material 64 are joined so that the core material 51 is screwed to both ends of the bolt 74.

この接合金物１１では、ボルト７４が中心に通っており、各部材の一体性がきわめて高いので、強固な接合状態を得られる。 In this metal joint 11, the bolt 74 passes through the center, and the integrity of each member is extremely high, so that a strong joint state can be obtained.

（小屋組用の接合金物）
図２６は、小屋組の一例を示し、線材としての棟束６６の上端に、線材としての複数本の垂木６７を接合する小屋組の例を示す縦断面図である。この図に示すように、接合金物１１は平面視六角形をなす下板２７と、これと相似形で下板２７よりも大きい上板２６と、これらを上下に挟み込むように取り付けられる６個の屈曲板２５で外郭部２１が形成され、この外郭部２１内には、上下に延びて下板２７と上板２６を結合する支柱部３１を有する。 (Joint fittings for huts)
FIG. 26 is a longitudinal cross-sectional view showing an example of a cabin set, in which an example of a cabin set in which a plurality of rafters 67 as wire rods are joined to the upper end of a bundle 66 as a wire rod. As shown in this figure, the metal joint 11 includes a lower plate 27 having a hexagonal shape in plan view, an upper plate 26 having a similar shape and larger than the lower plate 27, and six pieces attached so as to sandwich them vertically. An outer shell portion 21 is formed by the bent plate 25, and a column portion 31 that extends vertically and connects the lower plate 27 and the upper plate 26 is formed in the outer shell portion 21.

下板２７と上板２６の中央には貫通孔２７ａ，２６ａが形成され、上板２６の貫通孔２６ａには雌ねじが形成されている。また各屈曲板２５は短冊状の金属板からなり、長さ方向の中間部に接合面２２が形成され、この接合面２２の両端に結合面２５ｂが形成されている。接合面２２と上の結合面２５ｂの間が鋭角で、接合面２２と下の結合面２５ｂとの間が鈍角である。 Through holes 27 a and 26 a are formed in the center of the lower plate 27 and the upper plate 26, and female screws are formed in the through holes 26 a of the upper plate 26. Each bent plate 25 is made of a strip-shaped metal plate, and a joining surface 22 is formed at an intermediate portion in the length direction, and joining surfaces 25b are formed at both ends of the joining surface 22. There is an acute angle between the joint surface 22 and the upper joint surface 25b, and an obtuse angle between the joint surface 22 and the lower joint surface 25b.

このような小屋組用の接合金物１１は、支柱部３１を挟むように上板２６と下板２７を配置して、６個の屈曲板２５で挟むように組みつけてねじ部材２８で固定する。そして、上板２６から下板２７を突き抜ける長さのボルト７５とコア材５１とドリフトピン５５を用いて、接合金物１１の下端を棟束６６の上端の端面６１ａに固定する。つぎに、六方の接合面２２に垂木６７の端面６１ａを接合する。 Such a metal fitting 11 for a hut assembly has an upper plate 26 and a lower plate 27 disposed so as to sandwich the support column 31, and is assembled so as to be sandwiched between the six bent plates 25 and fixed by the screw member 28. . Then, the lower end of the metal joint 11 is fixed to the end surface 61 a at the upper end of the ridge bundle 66 by using the bolt 75, the core material 51, and the drift pin 55 having a length that penetrates the lower plate 27 from the upper plate 26. Next, the end surface 61 a of the rafter 67 is joined to the hexagonal joining surface 22.

なお、ユニットハウスの組み立てのときのように吊り下げるには、上記のボルト７５の頭部に、図２６に仮想線で示したような吊り部７５ａを有するものを使用するとよい。 In addition, in order to suspend like a unit house assembling, it is good to use what has the hanging part 75a as shown by the virtual line in FIG.

接合金物１１が上記のように構成されて小屋組の接合に用いられると、接合される棟束６６の端面６１ａと、６本の垂木６７の端面６１ａは、接合金物１１の外郭部２１を構成する接合面２２に突き当たった状態で固定される。このとき、棟束６６と垂木６７の側面と端面６１ａとが面接触する、噛み合ったような接合状態とはならず、端面６１ａの縁が当接するような接合となって、端面６１ａで囲まれる空間内に接合金物１１が埋没する状態となる。このため、棟束６６や垂木６７の交換が容易に行え、長期間にわたって使用できる優良な建築物を得ることかできる。 When the metal joint 11 is configured as described above and is used for joining the cabin set, the end surface 61a of the bunches 66 to be joined and the end surfaces 61a of the six rafters 67 constitute the outer portion 21 of the metal joint 11. It fixes in the state which contact | abutted to the joining surface 22 to do. At this time, the side surface of the ridge bundle 66 and the rafter 67 and the end surface 61a are brought into surface contact with each other, and are not in a joined state such that the edges of the end surface 61a come into contact with each other, and are surrounded by the end surface 61a. The joint hardware 11 is buried in the space. For this reason, the building bundle 66 and the rafter 67 can be easily replaced, and an excellent building that can be used for a long period of time can be obtained.

しかも、接合金物１１と棟束６６および垂木６７の接合は、ボルト７５，４１とコア材５１とドリフトピン５５とによる簡素な構造で接合でき、作業は簡単である。そのうえ、棟束６６や垂木６７に対する加工も少なくて済み、欠損をなくすことができる。このため、面同士が密に接した強固な固定状態が得られる。 Moreover, the joining hardware 11, the bunches 66 and the rafters 67 can be joined with a simple structure using the bolts 75 and 41, the core material 51, and the drift pin 55, and the work is simple. In addition, processing on the bunches 66 and rafters 67 can be reduced, and defects can be eliminated. For this reason, the firm fixed state which surfaces contact | connected closely is obtained.

また、外郭部２１の内部には支柱部３１が保持されているので、縦横の荷重に耐え得る堅固な構造にでき、頑丈な建築物を得ることができる。 Moreover, since the support | pillar part 31 is hold | maintained inside the outer part 21, it can be set as the firm structure which can bear the load of length and breadth, and a sturdy building can be obtained.

しかも、外郭部２１は、短冊状をなす金属板を長さ方向に折曲した６個の屈曲板２５を組み立てて形成されるので、棟木６６と垂木６７の端面６１ａ間に埋没する形状でありながらも、材料を少なくすることができ、コストの低減や軽量化にも資する。 In addition, the outer shell portion 21 is formed by assembling six bent plates 25 obtained by bending a metal plate having a strip shape in the length direction, so that it is buried between the purlin 66 and the end surface 61a of the rafter 67. However, the material can be reduced, which contributes to cost reduction and weight reduction.

図２７は、たとえば平面視六角形などの異形建築物を構成するのに用いられる異形建築物用の接合金物１１を用いた異形建築物の一部破断平面図である。図２７では梁部の状態を示しているが、柱脚部でも同様である。 (Joint hardware for odd-shaped buildings)
FIG. 27 is a partially cutaway plan view of a deformed building using a joint metal 11 for a deformed building used to form a deformed building such as a hexagon in plan view. FIG. 27 shows the state of the beam portion, but the same applies to the column base.

この図に示すように、外郭部２１は、外側が鈍角に突出し、内側が鈍角に凹む平面視凹多角形状をなす上板２６と下板２７と、これらにおける所定角度で対向する２辺に取り付けられる２個の屈曲板２５とで外郭部２１が構成される。そして、上板２６と下板２７の間に突っ張るように円柱状の支柱部３１が保持される。支柱部３１の構造は、図２や図１５の場合と同様である。 As shown in this figure, the outer portion 21 is attached to two sides facing each other at a predetermined angle, with an upper plate 26 and a lower plate 27 having a concave polygonal shape in plan view in which the outside protrudes at an obtuse angle and the inside is recessed at an obtuse angle. The outer portion 21 is configured by the two bent plates 25 formed. A columnar column 31 is held so as to stretch between the upper plate 26 and the lower plate 27. The structure of the column part 31 is the same as that of FIG. 2 and FIG.

具体的な形状は異なるものの、基本的な構成は先に説明した接合金物のそれと同一であるので、同一または同等の部位については同一の符号を付してその詳しい説明を省略する。 Although the specific shape is different, the basic configuration is the same as that of the joint hardware described above, and therefore, the same or equivalent parts are denoted by the same reference numerals and detailed description thereof is omitted.

接合金物１１が上記のように構成されて異形建築物の梁部や柱脚部の接合に用いられると、接合される各線材６１の端面６１ａは、接合金物１１の外郭部２１を構成する接合面２２に突き当たった状態で固定される。このとき、線材６１の側面と端面６１ａとが面接触する、噛み合ったような接合状態とはならず、端面６１ａの縁が当接するような接合となって、端面６１ａで囲まれる空間内に接合金物１１が埋没する状態となる。このため、線材６１の交換が容易に行え、長期間にわたって使用できる優良な建築物を得ることができる。 When the joint hardware 11 is configured as described above and used for joining the beam portion or the column base portion of the odd-shaped building, the end surface 61a of each wire 61 to be joined is a joint constituting the outer portion 21 of the joint hardware 11. It is fixed in a state where it abuts against the surface 22. At this time, the side surface of the wire 61 and the end surface 61a are in surface contact with each other, and are not joined as if they are engaged with each other, but are joined so that the edges of the end surface 61a come into contact with each other, and are joined in the space surrounded by the end surface 61a. The hardware 11 is buried. For this reason, the wire 61 can be easily replaced, and an excellent building that can be used over a long period of time can be obtained.

しかも、接合金物１１と線材６１の接合は、ボルト３２，４１とコア材５１とドリフトピン５５とによる簡素な構造で接合でき、作業は簡単である。そのうえ、線材６１に対する加工も少なくて済み、欠損をなくすことができる。このため、面同士が密に接した強固な固定状態が得られる。 In addition, the joining hardware 11 and the wire 61 can be joined with a simple structure using the bolts 32 and 41, the core material 51, and the drift pin 55, and the work is simple. In addition, processing for the wire 61 can be reduced, and defects can be eliminated. For this reason, the firm fixed state which surfaces contact | connected closely is obtained.

しかも、外郭部２１を構成する屈曲板２５は弓形をなし、その長さ方向の中心に接合面２２が形成されているので、左右方向での圧縮や引っ張りに強く、堅固な建築物を得ることができる。 In addition, the bent plate 25 constituting the outer portion 21 has an arcuate shape, and the joining surface 22 is formed at the center in the length direction, so that it is resistant to compression and pulling in the left-right direction, and a solid building is obtained. Can do.

また、外郭部２１は、弓形をなす２個の屈曲板を組み立てて形成されるので、線材６１の端面６１ａ間に埋没する形状でありながらも、材料を少なくすることができ、コストの低減や軽量化にも資する。 Further, since the outer shell portion 21 is formed by assembling two bent plates having an arcuate shape, the material can be reduced while the shape is buried between the end surfaces 61a of the wire rod 61. Contributes to weight reduction.

（その他の形態）
上記の一形態では１個に付き１個の接合面２２を有する屈曲板２５で外郭部２１を構成したが、図２８、図２９に示したように外郭部２１を構成する部材を、接合面２２を相対向する位置に２個有する側面視略長方形枠状に形成し、これらの組み合わせで外郭部２１が構成されるようにすることなどもできる。 (Other forms)
In the above embodiment, the outer portion 21 is constituted by the bent plate 25 having one joining surface 22 per one. However, as shown in FIGS. 28 and 29, the members constituting the outer portion 21 are connected to the joining surface. It is also possible to form a substantially rectangular frame shape in side view having two 22 at opposite positions, and to form the outer portion 21 by a combination thereof.

図２８は、他の例に係る柱脚部用の接合金物１１の斜視図、図２９はその分解斜視図であるが、梁部用や小屋組用、異形建築物用などでも同様である。 FIG. 28 is a perspective view of a joint 11 for a column base part according to another example, and FIG. 29 is an exploded perspective view thereof. However, the same applies to a beam part, a hut assembly, a deformed building, and the like.
