The brace fixing portion extends over the entire length of the column receiving member. , To provide a damping hardware.

本考案は、上記した課題を解決するための手段により、次のような効果の少なくとも一つを得ることができる。
（１）小変形〜中変形に対しては、粘弾性体により制振機能が働く。
（２）大変形に対しては、変位抑止部材によって変位が制限されることにより耐震機能が働く。
（３）許容を超える大変形によって粘弾性体の制振機能が喪失する前に変位を制限することにより、耐震機能と合わせて制振機能を維持できる。
（４）筋かい固定部が制振金物の全長に亘っているため、梁せいや柱の太さに合わせた筋かいの位置に対応することができる。 The present invention can obtain at least one of the following effects by means for solving the above-described problems.
(1) For small deformation to medium deformation, the vibration damping function works by the viscoelastic body.
(2) For large deformations, the displacement is restricted by the displacement restraining member, so that the seismic resistance function works.
(3) By limiting the displacement before the damping function of the viscoelastic body is lost due to a large deformation exceeding the tolerance, the damping function can be maintained together with the seismic function.

The column receiving member 11 abuts the outside of one plane forming one side of the L-shape with the column member 2a and is fixed by screws 7 (FIG. 3). Since it fixes with the screw 7 in the state which contact | abutted the plane, it can attach easily and the brace receiving member 12 is adhere | attached inside the other plane.
On the surface of the column receiving member 11 to which the brace receiving member 12 is bonded, a vertically long hole 111 that is long in the vertical direction is provided near the upper end and the lower end.

（２−２）筋かい受け部材
筋かい受け部材１２は鋼板であり、柱受け部材１１に接着する接着部１２１と、柱受け部材から延出する筋かい固定部１２２と、からなる。
筋かい受け部材１２は、接着部１２１を柱受け部材１１と接着した際に、筋かい固定部１２２が柱受け部材１１の全長に亘って延出する。
筋かい受け部材１２の側面と柱受け部材１１や柱材２ａとの間には間隔を設ける。
筋交い受け部材１２は平板であり、平面を当接した状態でビスにより筋かい４、６を固定するため、容易に取り付けることができる。
筋かい受け部材１２の筋かい固定部１２２は、柱受け部材１１の全長に亘っている。このため、筋かい４、６を固定する高さを自由に選択でき、梁せいや柱の太さに合わせた筋かいの位置に対応することができる。
筋かい受け部材１２には、柱受け部材１１の縦長孔１１１に対応してボルト孔１２３を設ける。
そして、縦長孔１１１とボルト孔１２３を重ね合わせた状態で、柱受け部材１１と筋かい受け部材１２を貫通するように、変位抑制部材１４となるボルト１４１を縦長孔１１１およびボルト孔１２３に挿通してナット１４２を螺合する。 (2-2) Brace receiving member The brace receiving member 12 is a steel plate, and includes an adhesive portion 121 that adheres to the column receiving member 11 and a brace fixing portion 122 that extends from the column receiving member.
In the brace receiving member 12, the brace fixing portion 122 extends over the entire length of the column receiving member 11 when the bonding portion 121 is bonded to the column receiving member 11.
A space is provided between the side surface of the brace receiving member 12 and the column receiving member 11 or the column member 2a.
The brace receiving member 12 is a flat plate, and since the braces 4 and 6 are fixed with screws in a state where the flat surface is in contact, the brace receiving member 12 can be easily attached.
The brace fixing portion 122 of the brace receiving member 12 extends over the entire length of the column receiving member 11. For this reason, the height which fixes the braces 4 and 6 can be selected freely, and it can respond to the position of the brace according to the beam or the thickness of the column.
The brace receiving member 12 is provided with a bolt hole 123 corresponding to the vertically long hole 111 of the column receiving member 11.
Then, in a state where the vertically long hole 111 and the bolt hole 123 are overlapped, the bolt 141 serving as the displacement suppressing member 14 is inserted into the vertically long hole 111 and the bolt hole 123 so as to penetrate the column receiving member 11 and the brace receiving member 12. Then, the nut 142 is screwed.

（２−３）粘弾性体
粘弾性体１３は高減衰ゴム、アクリルゴム等からなる。
粘弾性体１３は、一方の面を柱受け部材１１に接着し、他方の面を筋かい受け部材１２の接着部１２１に接着して、柱受け部材１１と筋かい受け部材１２とを一体にする。（図３、図４）
粘弾性体１３の両面に柱受け部材１１及び筋かい受け部材１２を接着することにより、粘弾性体１３は、柱受け部材１１と筋かい受け部材１２の相対的な変位に合わせて変形し、制振を行う。 (2-3) Viscoelastic body The viscoelastic body 13 is made of high damping rubber, acrylic rubber, or the like.
The viscoelastic body 13 has one surface bonded to the column receiving member 11 and the other surface bonded to the bonding portion 121 of the brace receiving member 12 so that the column receiving member 11 and the brace receiving member 12 are integrated. To do. (Fig. 3, Fig. 4)
By adhering the column support member 11 and the brace receiving member 12 to both surfaces of the viscoelastic body 13, the viscoelastic body 13 is deformed in accordance with the relative displacement of the column support member 11 and the brace receiving member 12, Vibration suppression is performed.

（２−４）スケール
制振金物１には、変位量を目視するためのスケール１５を設ける。
スケール１５は、例えば、柱受け部材１１に長孔状のスケール孔１５１と、筋かい受け部材のスケール孔１５１の中央に対応する位置に形成したボルト孔１５２と、スケール孔１５１およびボルト孔１５２に挿通するボルト１５３およびボルト１５３に螺合するナット１５４によって構成する。
柱受け部材１１と筋かい受け部材１２の相対的な変位によってボルト１５２がスケール孔１５１の長さ方向端部に到達し、さらにそれ以上変位するとボルト１５２が折曲するような太さに構成する。折曲するときのボルト１５２の変位量は、変位抑制部材１４と柱受け部材１２の縦長孔１１１の長さ方向端部との間隔よりも短くする。（図５ａ） (2-4) Scale A damping metal 1 is provided with a scale 15 for visually observing the amount of displacement.
The scale 15 includes, for example, a long hole-shaped scale hole 151 in the pillar receiving member 11, a bolt hole 152 formed at a position corresponding to the center of the scale receiving member 151, and the scale hole 151 and the bolt hole 152. A bolt 153 to be inserted and a nut 154 screwed into the bolt 153 are configured.
The bolt 152 reaches the end in the length direction of the scale hole 151 due to the relative displacement of the column receiving member 11 and the brace receiving member 12, and the bolt 152 is configured to be bent when further displaced. . The amount of displacement of the bolt 152 when bending is made shorter than the distance between the displacement suppressing member 14 and the longitudinal end of the longitudinally long hole 111 of the column receiving member 12. (Fig. 5a)

（３）制振機能
（３−１）小変形〜中変形
地震により木造住宅に力が作用すると、柱材２ａ、２ｂに傾きが生じる。そして、柱材２ａと筋かい４、６とが変位し、それに合わせて柱受け部材１１と筋かい受け部材１２とが相対的に変位する。
筋かい４、６は筋かい受け部材１２に固定されているため、筋かい４、６と筋かい受け部材１２は柱材２ａ及び柱受け部材１１に対して上下方向に変位し、この変位に合わせて粘弾性体１３が変形し、制振機能が働く。
このとき、筋かい４、６は筋かい受け部材１２に固定されているが、柱材２ａには接触していないため、変位による力は柱材２ａに直接作用せずに分散される。 (3) Vibration control function (3-1) Small deformation to medium deformation When a force acts on a wooden house due to an earthquake, the column members 2a and 2b are inclined. Then, the column member 2a and the braces 4 and 6 are displaced, and the column receiving member 11 and the brace receiving member 12 are relatively displaced accordingly.
Since the braces 4 and 6 are fixed to the brace receiving member 12, the braces 4 and 6 and the brace receiving member 12 are displaced in the vertical direction with respect to the column member 2a and the column receiving member 11, and this displacement is caused. At the same time, the viscoelastic body 13 is deformed and the vibration damping function works.
At this time, the braces 4 and 6 are fixed to the brace receiving member 12 but are not in contact with the pillar material 2a, so that the force due to the displacement is dispersed without directly acting on the pillar material 2a.

（３−２）大変形
柱受け部材１１と筋かい受け部材１２には、縦長孔１１１が設けられており、それに変位抑制部材１４が挿通されている。
このため、木造住宅に作用する力が大きくなると、柱材２ａと筋かい４、６との変位量が大きくなり、筋かい受け部材１２は、縦長孔１１１に沿って上下方向に変位する。
この変位により、制振機能と合わせて、力が筋かい４、６を介して分散されて、大きな力であっても壁構造が破壊されることがない。
筋かい受け部材１２の側面と柱受け部材１１や柱材２ａとの間には間隔を設けてあるため、大変形時でも筋かい受け部材１２が柱材２ａにめり込んで柱材２ａを破損することを防止できる。 (3-2) Large Deformation The columnar receiving member 11 and the brace receiving member 12 are provided with a vertically long hole 111, through which a displacement suppressing member 14 is inserted.
For this reason, when the force acting on the wooden house is increased, the amount of displacement between the column member 2 a and the brace 4, 6 is large, and the brace receiving member 12 is displaced in the vertical direction along the vertically long hole 111.
Due to this displacement, the force is distributed through the braces 4 and 6 together with the vibration damping function, and the wall structure is not destroyed even with a large force.
Since a space is provided between the side surface of the brace receiving member 12 and the column receiving member 11 or the column member 2a, the brace receiving member 12 is sunk into the column member 2a even in a large deformation and damages the column member 2a. Can be prevented.

（３−３）変位の抑制
柱受け部材１１と筋かい受け部材１２が、縦長孔１１１の長さ以上変位するような大変形の場合には、変位抑制部材１４が縦長孔１１１の長さ方向の端部に接触して変位を制限する。
よって、小変形〜中変形の際には、縦長孔１１１の範囲で相対変位し、その際の粘弾性体１３の変形によってエネルギーを吸収し、制振を行う。そして粘弾性体１３の変位量の制限を超えるような大変形に対しては、変位抑制部材１４によって変位が制限されることにより耐震機能が働くととも、粘弾性体１３の破断を防止する。粘弾性体１３は、破断されなければ、制限された変位量の範囲で制振機能を維持することができる。 (3-3) Suppression of displacement When the column receiving member 11 and the brace receiving member 12 are largely deformed so as to be displaced more than the length of the vertically long hole 111, the displacement suppressing member 14 is in the length direction of the vertically long hole 111. The displacement is limited by contacting the end of the plate.
Therefore, in the case of small deformation to medium deformation, relative displacement is performed in the range of the vertically long hole 111, and energy is absorbed by the deformation of the viscoelastic body 13 at that time, and vibration is suppressed. For a large deformation exceeding the limit of the displacement amount of the viscoelastic body 13, the displacement is restricted by the displacement suppressing member 14, and the seismic function functions and the fracture of the viscoelastic body 13 is prevented. If the viscoelastic body 13 is not broken, the damping function can be maintained within a limited displacement range.

（３−４）スケールによる変位量の検知
制振金物１にはスケール１５を設けてあるが、このスケール１５は、変位抑制部材１４と柱固定部材１１の縦長孔１１１の長さ方向端部との間隔よりも短い変位を検知する。（図５ｂ）
これにより、粘弾性体１３が小〜中変形した際の変位を検知でき、粘弾性体１３の寿命を確認することができる。 (3-4) Detection of displacement amount by scale A scale 15 is provided on the vibration control metal 1, and the scale 15 includes a displacement suppressing member 14 and end portions in the lengthwise direction of the elongated holes 111 of the column fixing member 11. Displacement shorter than the interval is detected. (Fig. 5b)
Thereby, the displacement when the viscoelastic body 13 is deformed from small to medium can be detected, and the life of the viscoelastic body 13 can be confirmed.
