Description

本発明は、木造建造物を構成する木製部材を接合する際に使用する木造構造物用の接合金物に関する。   The present invention relates to a metal fitting for a wooden structure used when joining wooden members constituting a wooden structure.

土台と柱の接合部など、第1木材と第2木材とが直角に接合した接合部を補強する場合には、第1金物片と第2金物片とを直角に折り曲げた接合金物を使用していた。この場合、接合部に荷重が作用した際に、接合金物の第1金物片と第2金物片との直角を維持して、また接合金物の第1金物片および第2金物片がめくれ上がったりせずに、それぞれ第1木材、第2木材との表面に密着性していることが必要となっていた。   To reinforce a joint where the first wood and the second wood are joined at right angles, such as a joint between the base and the pillar, use a joint hardware obtained by bending the first hardware piece and the second hardware piece at a right angle. It was. In this case, when a load is applied to the joint, the right angle between the first hardware piece and the second hardware piece of the joining hardware is maintained, and the first hardware piece and the second hardware piece of the joining hardware are turned up. In addition, it was necessary to adhere to the surfaces of the first wood and the second wood, respectively.

これを維持するために、第1金物片と第2金物片との間に深い補強リブを形成し(特許文献1図10)、あるいは第1金物片と第2金物片の外側とに補強板を連設して(特許文献1図8、図14)、構成していた。また、補強リブと補強板の両方を形成する場合もあった(特許文献2)。   In order to maintain this, a deep reinforcing rib is formed between the first hardware piece and the second hardware piece (FIG. 10 of Patent Document 1), or a reinforcing plate on the outside of the first hardware piece and the second hardware piece. (Patent Document 1 FIGS. 8 and 14). In some cases, both a reinforcing rib and a reinforcing plate are formed (Patent Document 2).

また、第1金物片と第2金物片との間に、帯状膨出リブを形成する提案もあった(特許文献3)。また、第1金物片と第2金物片とが直角に接合された金物ではないが、比較的浅い凸条を縦横に交叉させて突出方向で一体の浅い凸条、あるいは円状の凸条を設けて補強をする提案もあった(特許文献4)。   There has also been a proposal to form a belt-like bulging rib between the first hardware piece and the second hardware piece (Patent Document 3). In addition, the first metal piece and the second metal piece are not a metal object joined at a right angle, but a relatively shallow ridge is crossed vertically and horizontally to form an integral shallow ridge or a circular ridge in the protruding direction. There was also a proposal to provide and reinforce (Patent Document 4).

Moreover, in each said invention, it is the following structure, It is the joining metal fitting for wooden structures characterized by the above-mentioned.
(1) When the thickness of the hardware base material is t0,
A level difference t1 between the surface of the metal base material and the surface of the first bulge portion,

前記における「第2膨出部は、第1膨出部より深い構造で形成した。」とは、「金物基材の表面と第1膨出部の表面との距離(長さ)」より、「第1膨出部の表面と第2膨出部の表面との距離(長さ)」が大きいことをいう。一般に、第1膨出部の表面は平坦な構造を想定しているが、第2膨出部の表面は凹凸があることも想定され、さらに金物基材は第1金物基材片と第2金物基材片とで構成される。したがって、第1金物基材片と第2金物基材片とのそれぞれにおいて、あるいは第1金物基材片と第2金物基材片の全体において、さらに金物基材の表面、第1膨出部の表面、あるいは第2膨出部の表面の凹凸にかかわらず、前記における大きさの比較は、平均や最大での大きさで判断される。   In the above, “the second bulging portion is formed in a structure deeper than the first bulging portion” means “the distance (length) between the surface of the metal base and the surface of the first bulging portion”. “The distance (length) between the surface of the first bulge and the surface of the second bulge” is large. In general, the surface of the first bulge portion is assumed to have a flat structure, but the surface of the second bulge portion is also assumed to have irregularities, and the metal base material is composed of the first metal base material piece and the second metal base material piece. It consists of a metal base piece. Therefore, in each of the first hardware base piece and the second hardware base piece, or in the whole of the first hardware base piece and the second hardware base piece, the surface of the hardware base, the first bulging portion Regardless of the unevenness of the surface or the surface of the second bulging portion, the comparison of the sizes is determined by the average or the maximum size.

この発明は、浅い第1膨出部(ビード加工)の中に、深い第2膨出部(リブ加工)を形成したので、接合金物の変形に対して、第1膨出部(ビード加工)はねじり剛性と効果範囲に優れ、第2膨出部(リブ加工)は曲げ剛性に優れている。したがって、第1膨出部(ビード加工)の中に、深い第2膨出部(リブ加工)を形成したので、両膨出部の効果を合わせ、より耐力を高めた接合金物を構成できる。このような接合金物は、とりわけ第1木材と第2木材とが直角に接合されかつ引き抜き力が作用するような接合部での適用が最適である。   In the present invention, since the deep second bulge portion (rib processing) is formed in the shallow first bulge portion (bead processing), the first bulge portion (bead processing) against the deformation of the joint hardware. Is excellent in torsional rigidity and effective range, and the second bulging portion (rib processing) is excellent in bending rigidity. Therefore, since the deep 2nd bulge part (rib process) was formed in the 1st bulge part (bead process), the effect of both bulge parts was match | combined and the joining metal hardware which raised the yield strength can be comprised. Such a joint metal fitting is optimally applied particularly at a joint where the first wood and the second wood are joined at right angles and a pulling force acts.

第1金物片5、第2金物片15で、木材に当接する面を裏面7a、17aとし、裏面7a、17aの他面を表面7、17とする。すなわち、第1金物片5、第2金物片15で90°(=θ)で対向している面が表面7、17となり、270°となっている側が裏面7a、17aとなる(図1(c))。
また、第1金物片5、第2金物片15で、屈曲線3を基端とした場合、自由端側(屈曲線3の反対側)を先端6、16とする(図1)。
(1) The steel plate is bent at about 90 ° to form the metal base 1 composed of the first metal piece 5 and the second metal piece 15. A boundary between the first hardware piece 5 and the second hardware piece 15, that is, a bent position is defined as a bending line 3. The first metal piece 5 is a member that is fixed in close contact with the surface of the first wood, and the second metal piece 15 is a member that is fixed in close contact with the surface of the second wood. Therefore, when the bending line 3 is viewed in the axial direction, the side of the first hardware piece 5 and the side of the second hardware piece 15 intersect at an angle θ (angle θ = 90 °) with the bending line 3 as the center. (FIG. 1 (c)).
In the first metal piece 5 and the second metal piece 15, the surfaces contacting the wood are the back surfaces 7 a and 17 a, and the other surfaces of the back surfaces 7 a and 17 a are the front surfaces 7 and 17. That is, the surfaces of the first metal piece 5 and the second metal piece 15 facing each other at 90 ° (= θ) are the front surfaces 7 and 17, and the sides facing the 270 ° are the back surfaces 7 a and 17 a (FIG. 1 ( c)).

第1膨出部30は、いわゆるビードで、浅く形成し、第1木材当接部9(金物基材1)の厚さをt0とした場合、第1膨出部30の厚さもt0で、第1木材当接部9の表面11と第1膨出部30の表面31との段差の距離t1とすると、
t1=(0.4〜0.5)×t0
程度で形成する。なお、第1木材当接部9の裏面と第1膨出部30の裏面との段差もt1となっている(図示していない)。
同様に、第2木材当接部19(金物基材1)の厚さもt0で、第2木材当接部19の表面21と第1膨出部30の表面31との段差の距離t1とすると、
t1=(0.4〜0.5)×t0
程度で形成されている。なお、第2木材当接部19の裏面と第1膨出部30の裏面との段差もt1となっている(図示していない)。
したがって、第1膨出部30は、第1金物片5側と第2金物片15側で表面7、11(裏面7a、17a)は90°の角度になっており、金物基材1の屈曲線3に応じた第1膨出部30の屈曲線32が形成される(図1(a)(b)、図2)。
