Description

本発明は、構造が簡易でコンパクトな履歴型ダンパ及び制震構造に関する。 The present invention relates to a hysteretic damper and a vibration control structure that are simple in structure and compact.

従来、柱と梁を有する門型の構造物の耐震性を高める為、ブレースや方杖等が用いられているが、構造物の制震を行う為、これらの一部にダンパを設ける場合がある。ダンパには、流体抵抗を利用した油圧ダンパ、摩擦抵抗を利用した摩擦ダンパ、部材の弾塑性変形を利用した履歴型ダンパ等がある。特に履歴型ダンパは、コストや取り扱いやすさに優れている。 Conventionally, braces and wands have been used to increase the earthquake resistance of gate-type structures with columns and beams. However, dampers may be provided on some of these structures to control the structures. is there. Examples of the damper include a hydraulic damper using fluid resistance, a friction damper using friction resistance, and a hysteretic damper using elastic-plastic deformation of a member. In particular, the hysteresis damper is excellent in cost and ease of handling.

履歴型ダンパにも種々の構造があり、ブレースに取り付けられるダンパとしては、従来から知られる座屈拘束型ブレースがある。座屈拘束型ブレースは、コンクリートの内部に鋼材を埋設した構造を有する。しかしこのような方式では、コンパクトにダンパを構成することができず、また、取替え作業を単純化することができない。このような問題に対し、鋼材のみから構成されるダンパとして、(1)3段のフランジと、フランジと直交する2段のウェブ部を有し、横断面形状が「王」字状となるエネルギー吸収体を有するブレースダンパ(特許文献1)(2)筒体部または湾曲部と平板部とを接合してなるダンパ(特許文献2)や、(3)平板を湾曲させ、平板部と湾曲部からなるダンパ(特許文献3)、がある。

Hysteretic dampers also have various structures, and conventionally known buckling-restrained braces are known as dampers attached to the braces. The buckling-restrained brace has a structure in which a steel material is embedded inside concrete. However, in such a system, the damper cannot be configured in a compact manner, and the replacement work cannot be simplified. In order to solve such problems, as a damper composed of only steel materials, (1) energy having a three-stage flange and a two-stage web portion orthogonal to the flange and having a cross-sectional shape of a “king” shape. A brace damper having an absorber (Patent Document 1) (2) A damper (Patent Document 2) formed by joining a cylindrical body portion or a curved portion and a flat plate portion, or (3) a flat plate, and a flat plate portion and a curved portion There is a damper made of (Patent Document 3).
JP 2000-199279 A JP 2001-207679 A JP 2006-52824 A

しかしながら、(1)のブレースダンパは、振動によるエネルギーの吸収が、ダンパを構成する板部材の面内方向の変形によるものであるため、大きなエネルギーに対しては有効であるが、小さなエネルギーでは降伏を起こさせることが難しく、ダンパとしての機能を発揮せず、また、板部材の面外座屈という問題がある。 However, the brace damper (1) is effective for large energy because the absorption of energy due to vibration is due to deformation in the in-plane direction of the plate member constituting the damper. It is difficult to cause a problem, the function as a damper is not exhibited, and there is a problem of out-of-plane buckling of the plate member.

(2)のダンパでは筒体部または湾曲部の塑性変形を利用してエネルギーを吸収するため、ダンパ製造時の接合及び曲げ加工時の寸法ばらつき等の影響で、同一形状を得ることが難しく、同一条件下でも筒体部または湾曲部の変形が一定しない。また、筒体部または湾曲部を大変形させた時、ダンパの安定な減衰力特性を得ることが難しいという問題がある。 In the damper of (2), since the energy is absorbed by utilizing plastic deformation of the cylindrical part or the curved part, it is difficult to obtain the same shape due to the influence of the dimensional variation at the time of joining and bending at the time of manufacturing the damper, Even under the same conditions, the deformation of the cylindrical portion or the curved portion is not constant. Further, there is a problem that it is difficult to obtain a stable damping force characteristic of the damper when the cylindrical body portion or the curved portion is largely deformed.

(3)のダンパは、湾曲部および平板部の弾塑性変形にてエネルギーを吸収するものであるが、ダンパに湾曲箇所が多いため、ダンパ製造時の曲げ加工が困難であり、同一形状のダンパを得ることが難しい。また、ある程度以上の湾曲部の曲げ半径が必要である為、ダンパ自体が大型化するという問題がある。 The damper (3) absorbs energy by elastic-plastic deformation of the curved portion and the flat plate portion. However, since the damper has many curved portions, it is difficult to bend at the time of manufacturing the damper, and the damper having the same shape. Difficult to get. In addition, since the bending radius of the curved portion is required to some extent, there is a problem that the damper itself is enlarged.

以下、本発明の実施の形態を詳細に説明する。図1は本実施の形態に係る履歴型ダンパ1を示す図であり、図1(a)は履歴型ダンパ1の斜視図、図1(b)は履歴型ダンパ1の側面図である。履歴型ダンパ1は、一対の板状部材である平板部3と、直方体である連結部5等から構成される。一対の平板部3の両端は連結部5により連結され、一対の平板部3は略平行に設けられる。平板部3は、外力を受けると主に平板部の曲げ方向へ弾塑性変形し、これによりエネルギーを吸収し、構造体に減衰力を与える。 Hereinafter, embodiments of the present invention will be described in detail. 1A and 1B are diagrams showing a hysteresis damper 1 according to the present embodiment, in which FIG. 1A is a perspective view of the hysteresis damper 1 and FIG. 1B is a side view of the hysteresis damper 1. The hysteretic damper 1 includes a flat plate portion 3 that is a pair of plate members, a connecting portion 5 that is a rectangular parallelepiped, and the like. Both ends of the pair of flat plate portions 3 are connected by a connecting portion 5, and the pair of flat plate portions 3 are provided substantially in parallel. When receiving an external force, the flat plate portion 3 is elastically plastically deformed mainly in the bending direction of the flat plate portion, thereby absorbing energy and giving a damping force to the structure.

連結部5は、平板部3の端部で挟まれており、平板部3と連結部5は「口」字状に連結される。平板部3と連結部5は、貫通するボルト9、ナット11にて固定される。平板部3の略中央は、構造体との接合部7が設けられる。接合部7は、構造体との接合のためのボルト穴13が設けられる。 The connecting portion 5 is sandwiched between the end portions of the flat plate portion 3, and the flat plate portion 3 and the connecting portion 5 are connected in a “mouth” shape. The flat plate portion 3 and the connecting portion 5 are fixed by a penetrating bolt 9 and a nut 11. A substantially central portion of the flat plate portion 3 is provided with a joint portion 7 with the structure. The joint 7 is provided with a bolt hole 13 for joining to the structure.

平板部3は、弾塑性変形によりエネルギーを吸収する機能を有すれば、材質は特定しないが、例えば炭素鋼やステンレス鋼で良い。また、連結部5は、荷重入力時においても一対の平板部3を連結できれば良く、材質は特定しないが、例えば炭素鋼やステンレス鋼で良い。平板部3、連結部5の厚み、長さ、幅等は、取り付け状態や使用条件に応じて計算等により設定される。 The flat plate portion 3 is not specified as long as it has a function of absorbing energy by elastic-plastic deformation, but may be carbon steel or stainless steel, for example. Moreover, the connection part 5 should just be able to connect a pair of flat plate part 3 at the time of load input, and although a material is not specified, it may be carbon steel or stainless steel, for example. The thickness, length, width, and the like of the flat plate portion 3 and the connecting portion 5 are set by calculation or the like according to the mounting state and use conditions.

図2(a)〜図2(c)は、履歴型ダンパ1を構造体へ取り付けた制震構造を示す図である。図2(a)に示すように、構造体としての一対のV型(横向き、逆向きに設置されるものを含む。以下同じ)のブレース19a、19bへ履歴型ダンパ1が設けられる。ブレース19a、19bは、構造物の柱15、梁17により囲まれた角部の対角線上に、クロスするように設けられ、クロスする部位の上方がブレース19a、下方がブレース19bである。履歴型ダンパ1は、ブレース19a、19bが合流する位置に設けられる。 Fig.2 (a)-FIG.2 (c) are figures which show the damping structure which attached the hysteresis type damper 1 to the structure. As shown in FIG. 2A, the hysteretic damper 1 is provided on a pair of V-shaped braces 19a and 19b (including those installed in the horizontal direction and the reverse direction, the same applies hereinafter) as a structure. The braces 19a and 19b are provided so as to cross on the diagonal lines of the corners surrounded by the column 15 and the beam 17 of the structure. The braces 19a are above the crossed portions and the braces 19b are below. The hysteretic damper 1 is provided at a position where the braces 19a and 19b join.

ブレース19a、19bには、予め接合部材である接合板21が設けられる。ブレース19a、19bにそれぞれ設けられた接合板21は、履歴型ダンパ1の平板部3a、3bそれぞれの接合部7と図示を省略したボルトにより接合される。即ち、上方のブレース19aは履歴型ダンパ1の上方の平板部3aへ接合され、下方のブレース19bは、履歴型ダンパ1の下方の平板部3bへ接合される。なお、接合板21の材質は特定しないが、例えば炭素鋼やステンレス鋼で良い。 The braces 19a and 19b are previously provided with a joining plate 21 as a joining member. The joining plates 21 provided on the braces 19a and 19b are joined to the joining portions 7 of the flat plate portions 3a and 3b of the hysteresis damper 1 by bolts (not shown). That is, the upper brace 19 a is joined to the upper flat plate portion 3 a of the hysteresis type damper 1, and the lower brace 19 b is joined to the lower flat plate portion 3 b of the hysteresis type damper 1. Although the material of the joining plate 21 is not specified, for example, carbon steel or stainless steel may be used.

なお、履歴型ダンパ1は、図2(b)に示すように、それぞれの長さが異なる、構造体としての一対のV型のブレース19c、19dに設けられてもよい。すなわち、構造物の柱15、梁17により囲まれた角部の対角線上から、鉛直方向の上下いずれかの方向にずれた位置において、ブレース19c、19dが合流し、履歴型ダンパ1は、ブレース19c、19dが合流する位置に設けられてもよい。 As shown in FIG. 2B, the hysteretic damper 1 may be provided on a pair of V-type braces 19c and 19d as structures having different lengths. That is, the braces 19c and 19d merge at a position shifted in the vertical direction from the diagonal of the corner surrounded by the column 15 and the beam 17 of the structure, and the hysteretic damper 1 It may be provided at a position where 19c and 19d merge.

また、履歴型ダンパ1は、図2(c)に示すように、構造体としてのV型のブレース19eに設けられてもよい。すなわち、構造物の柱15、梁17の合流部から、上下いずれかの方向の梁17までV型ブレース19eが延長され、履歴型ダンパ1の一方の平板部3aが接合板21を介してブレース19eと接合され、履歴型ダンパ1のもう一方の平板部3bが接合板21を介して梁17と接合されてもよい。なお、以後の説明においては、履歴型ダンパ1は、図2(a)の取り付け状態で構造体と接合されているとして説明する。 Further, as shown in FIG. 2C, the hysteresis damper 1 may be provided in a V-shaped brace 19e as a structure. That is, the V-shaped brace 19e is extended from the joining portion of the column 15 and the beam 17 of the structure to the beam 17 in either the upper or lower direction, and one flat plate portion 3a of the hysteretic damper 1 is brazed via the joint plate 21. The other flat plate portion 3b of the hysteretic damper 1 may be joined to the beam 17 via the joining plate 21. In the following description, it is assumed that the hysteretic damper 1 is joined to the structure in the attached state of FIG.

次に、履歴型ダンパ1の動作について説明する。図3は、地震等により構造物が振動し、構造体であるブレース19a、19bが相対的に変位した状態を示す図であり、図3(a)は全体図、図3(b)は履歴型ダンパ1の拡大図である。図3(a)に示すように、地震や風などにより、梁17が矢印A方向へ変位し、ブレース19a、19bがそれぞれ相対的に変位すると、履歴型ダンパ1は変形部22で変形する。 Next, the operation of the hysteresis damper 1 will be described. FIG. 3 is a diagram showing a state in which the structure vibrates due to an earthquake or the like, and the braces 19a and 19b, which are structures, are relatively displaced. FIG. 3 (a) is an overall view, and FIG. 3 is an enlarged view of a mold damper 1. FIG. As shown in FIG. 3A, when the beam 17 is displaced in the direction of arrow A and the braces 19a and 19b are relatively displaced by an earthquake or wind, the hysteretic damper 1 is deformed by the deforming portion 22.

履歴型ダンパ1の変形は、平板部3の曲げ方向への弾塑性変形である。即ち、履歴型ダンパ1は、平板部3が曲げ方向へ弾塑性変形することで、外力のエネルギーを吸収する。なお、図3(b)に示すように、平板部3と連結部5との接合部や、構造体との接合部7はほとんど変形せず、エネルギー吸収にはほとんど寄与しない。即ち、実質的に変形を行う部位は、平板部3において、連結部5との接合部と、構造体との接合部7との間に位置する変形部22となる。 The hysteretic damper 1 is deformed by elastic-plastic deformation in the bending direction of the flat plate portion 3. That is, the hysteretic damper 1 absorbs the energy of external force by the elastic deformation of the flat plate portion 3 in the bending direction. In addition, as shown in FIG.3 (b), the junction part of the flat plate part 3 and the connection part 5, and the junction part 7 with a structure hardly deform | transform, and hardly contribute to energy absorption. That is, the portion that substantially deforms is the deformed portion 22 located between the joint portion with the connecting portion 5 and the joint portion 7 with the structure in the flat plate portion 3.

なお、平板部3の断面形状は一定でも良く、平板部3の幅および厚さのいずれか一方又は両方を変化させた変断面であってもよい。すなわち、変形部22の幅や厚みを変化させ、断面積を変化させてもよい。例えば、図4(a)は幅狭部24を有する履歴型ダンパ1の平面図であるが、平板部3の変形部22の一部に幅狭部24を設ければ、平板部3へ力が加わった際に、その幅狭部24を優先的に降伏させることができる。従って、減衰力を調整することができる。 In addition, the cross-sectional shape of the flat plate part 3 may be constant, or may be a variable cross section in which one or both of the width and thickness of the flat plate part 3 are changed. That is, the cross-sectional area may be changed by changing the width and thickness of the deformable portion 22. For example, FIG. 4A is a plan view of the hysteretic damper 1 having the narrow portion 24, but if the narrow portion 24 is provided in a part of the deformed portion 22 of the flat plate portion 3, force is applied to the flat plate portion 3. When the is added, the narrow portion 24 can be preferentially yielded. Accordingly, the damping force can be adjusted.

また、図4(b)はあて板26を有する履歴型ダンパ1の側面図であるが、変形部22の一部にあて板26を溶接等により接合し補強すれば、平板部3へ力が加わった際に、変形部22部の変形を抑制することができる。従って、減衰力を調整することができる。なお、あて板26の材質は特定しないが、例えば炭素鋼やステンレス鋼で良い。 4B is a side view of the hysteretic damper 1 having the contact plate 26. If the contact plate 26 is joined and reinforced to a part of the deformable portion 22 by welding or the like, a force is applied to the flat plate portion 3. FIG. When added, the deformation of the deformable portion 22 can be suppressed. Accordingly, the damping force can be adjusted. The material of the contact plate 26 is not specified, but may be, for example, carbon steel or stainless steel.

平板部3の一部や連結部5については、部分焼き入れなどを施した熱処理部28を設けても良い。例えば、図4(c)は、熱処理部28(ハッチング部)を有する履歴型ダンパ1の平面図であるが、連結部5近傍について部分焼入れを行い、部分的に部材の強度を上げた熱処理部28を設けることで、平板部3へ力が加わった際に、熱処理部28の変形を抑制し、降伏させる部位を特定する事ができる。従って、減衰力を調整することができる。 For a part of the flat plate part 3 and the connecting part 5, a heat treatment part 28 subjected to partial quenching or the like may be provided. For example, FIG. 4C is a plan view of the hysteretic damper 1 having the heat treatment portion 28 (hatching portion), and the heat treatment portion in which the strength of the member is partially increased by partially quenching the vicinity of the connecting portion 5. By providing 28, when force is applied to the flat plate portion 3, it is possible to suppress deformation of the heat treatment portion 28 and specify a portion to yield. Accordingly, the damping force can be adjusted.

次に、構造体と履歴型ダンパ1の取り付け状態による他の制震構造について説明する。図5(a)は、第2の制震構造を示す図であり、履歴型ダンパ1を鉛直方向にブレース19へ取り付けた状態を示す図である。図3(a)と同様に、ブレース19a、19bは、構造物の柱15、梁17により囲まれた角部の対角線上に、クロスするように設けられ、クロスする部位の一方の側(図中左側)がブレース19a、他方(図中右側)がブレース19bである。 Next, another damping structure according to the attachment state of the structure and the hysteresis damper 1 will be described. FIG. 5A is a diagram showing the second vibration control structure, and is a diagram showing a state in which the hysteretic damper 1 is attached to the brace 19 in the vertical direction. Similarly to FIG. 3A, the braces 19a and 19b are provided so as to cross on the diagonal line of the corner surrounded by the column 15 and the beam 17 of the structure, and one side of the crossing portion (FIG. The middle left side is the brace 19a, and the other side (right side in the figure) is the brace 19b.

ブレース19a、19bには予め接合板21が設けられる。履歴型ダンパ1は、ブレース19a、19bが合流する位置に設けられる。ブレース19a、19bにそれぞれ設けられた接合板21と、履歴型ダンパ1の平板部3a、3bのそれぞれの接合部7とが図示を省略したボルトにより接合される。地震等により構造物が振動し、構造体であるブレース19a、19bが相対的に変位すると、履歴型ダンパ1は図3(b)と同様に変形し、エネルギーを吸収することができる。 A joining plate 21 is provided in advance on the braces 19a and 19b. The hysteretic damper 1 is provided at a position where the braces 19a and 19b join. The joining plates 21 provided on the braces 19a and 19b and the joining portions 7 of the flat plate portions 3a and 3b of the hysteretic damper 1 are joined by bolts (not shown).

地震等により構造物が振動し、構造体である壁23a、23bが相対的に変位すると、履歴型ダンパ1は図3(b)と同様に変形し、エネルギーを吸収することができる。なお、壁23a、23bが相対的に変位可能とするため、壁23a、23bと梁17との間には隙間が設けられる。 When the structure vibrates due to an earthquake or the like and the walls 23a and 23b, which are structures, are relatively displaced, the hysteretic damper 1 is deformed similarly to FIG. 3B and can absorb energy. In addition, a gap is provided between the walls 23a and 23b and the beam 17 so that the walls 23a and 23b can be relatively displaced.

図8は、第5の制震構造を示す図であり、履歴型ダンパ1を水平方向に構造体である柱27に取り付けた状態を示す図である。柱27は、柱15、15間に設けられる。柱27a、27bはそれぞれ梁17と接合されており、柱27aは梁17から下方に設けられ、柱27bは梁17から上方へ設けられる。柱27a、27bには予め接合部材である接合板21が設けられる。柱27a、27bにそれぞれ設けられた接合板21と、履歴型ダンパ1の平板部3a、3bのそれぞれの接合部7は、図示を省略したボルト等により接合される。即ち、履歴型ダンパ1は、柱27a、27bとの間に、平板部3を水平方向にして設けられる。 FIG. 8 is a diagram showing a fifth seismic damping structure, and is a diagram showing a state in which the hysteretic damper 1 is attached to the pillar 27 as a structure in the horizontal direction. The column 27 is provided between the columns 15 and 15. Each of the columns 27 a and 27 b is joined to the beam 17, the column 27 a is provided below the beam 17, and the column 27 b is provided above the beam 17.

That is, the hysteretic damper 1 is provided with the flat plate portion 3 in the horizontal direction between the pillars 27a and 27b.

なお、履歴型ダンパ1の柱27への取り付け状態としては、図8に示す状態に限られず、図2(a)に示す履歴型ダンパ1の取り付け状態に対する図2(b)に示す履歴型ダンパ1の取り付け状態と同様であってもよい。すなわち、柱27a、27bの長さが異なり、履歴型ダンパ1の設置位置が、構造物の柱15、梁17により囲まれた角部の中心より、上下方向へずれた位置であっても良い。また、図2(a)に示す履歴型ダンパ1の取り付け状態に対する図2(c)に示す履歴型ダンパ1の取り付け状態と同様であってもよい。すなわち、柱27と梁17との間に履歴型ダンパ1が設けられても良い。 The mounting state of the hysteretic damper 1 to the column 27 is not limited to the state illustrated in FIG. 8, and the hysteretic damper illustrated in FIG. 2B with respect to the mounting state of the hysteretic damper 1 illustrated in FIG. 1 may be the same as the attached state. That is, the lengths of the pillars 27a and 27b may be different, and the installation position of the hysteretic damper 1 may be a position shifted in the vertical direction from the center of the corner surrounded by the pillars 15 and beams 17 of the structure. . Moreover, it may be the same as the mounting state of the hysteretic damper 1 shown in FIG. 2C with respect to the mounting state of the hysteretic damper 1 shown in FIG. That is, the hysteretic damper 1 may be provided between the column 27 and the beam 17.

地震等により構造物が振動し、構造体である柱27a、27bが相対的に変位すると、履歴型ダンパ1は図3(b)と同様に変形し、エネルギーを吸収することができる。 When the structure vibrates due to an earthquake or the like and the columns 27a and 27b, which are structures, are relatively displaced, the hysteretic damper 1 is deformed in the same manner as in FIG. 3B and can absorb energy.

このように、本実施の形態にかかる履歴型ダンパ1によれば、一対の平板部3と連結部5とを主な構成要素とし、これらをボルト9で接合するものであり、構造が簡易でコンパクトあり、履歴型ダンパ1の製造時において板の曲げ加工がなく製造も容易である。また、平板部3のストレート部を曲げ方向へ降伏させる為、湾曲部や筒体部の降伏や、板の面内方向に降伏させるよりも強度設計や制御が容易である。 Thus, according to the hysteresis type damper 1 concerning this Embodiment, a pair of flat plate part 3 and the connection part 5 are made into the main components, and these are joined with the volt | bolt 9, and a structure is simple. There is no need to bend the plate when manufacturing the hysteretic damper 1, and it is easy to manufacture. Further, since the straight portion of the flat plate portion 3 is yielded in the bending direction, strength design and control are easier than yielding of the curved portion and the cylindrical body portion and yielding in the in-plane direction of the plate.

また、柱15と梁17で囲まれた一つの四辺形部の対角線長さが長く、構造体が長い場合でも、履歴型ダンパ1は一対の構造体のほぼ中央に設けられることができるため、構造体の座屈が抑えることができる。また、一つの四辺形部に対して、複数の履歴型ダンパを用いる必要がなく、一体の履歴型ダンパ1を設けることで、制震効果を得ることができるため、効率が良い。 In addition, even when the diagonal length of one quadrangular portion surrounded by the column 15 and the beam 17 is long and the structure is long, the hysteretic damper 1 can be provided at substantially the center of the pair of structures. The buckling of the structure can be suppressed. In addition, it is not necessary to use a plurality of hysteresis dampers for one quadrilateral portion, and providing the integral hysteresis damper 1 provides a vibration control effect, which is efficient.

次に、第2の実施の形態について説明する。図9は第2の実施の形態に係る履歴型ダンパ30を示す図である。以下の実施の形態において、図1に示す履歴型ダンパ1と同一の機能を果たす構成要素には、図1と同一番号を付し、重複した説明を避ける。 Next, a second embodiment will be described. FIG. 9 is a diagram showing a hysteretic damper 30 according to the second embodiment. In the following embodiment, components having the same functions as those of the hysteresis type damper 1 shown in FIG.

履歴型ダンパ30は、平板部3と連結部5との接合部に、平板部3の幅方向に溝状の凹部31を有する。凹部31は、連結部5の幅と略同一幅であり、連結部5は凹部31へ勘合される。平板部3と凹部31へ嵌合された連結部5は、貫通するボルト9、ナット11によって固定される。 The hysteretic damper 30 has a groove-shaped recess 31 in the width direction of the flat plate portion 3 at the joint between the flat plate portion 3 and the connecting portion 5. The recessed portion 31 has substantially the same width as the width of the connecting portion 5, and the connecting portion 5 is fitted into the recessed portion 31. The connecting portion 5 fitted to the flat plate portion 3 and the concave portion 31 is fixed by a bolt 9 and a nut 11 that pass therethrough.

履歴型ダンパ30の接合部7を、履歴型ダンパ1と同様に構造体へ接合し、地震等により構造体から力を受けると、図3(b)における履歴型ダンパ1と同様に履歴型ダンパ30の変形部22が弾塑性変形し、エネルギーを吸収する。この際、連結部5は凹部31に嵌合されている為、変形の際に連結部5と平板部3との間に相対するすべりが生じない。 When the joint 7 of the hysteretic damper 30 is joined to the structure in the same manner as the hysteretic damper 1 and receives a force from the structure due to an earthquake or the like, the hysteretic damper is similar to the hysteretic damper 1 in FIG. Thirty deformable portions 22 undergo elasto-plastic deformation and absorb energy. At this time, since the connecting portion 5 is fitted in the recess 31, no slip occurs between the connecting portion 5 and the flat plate portion 3 during deformation.

このように、第2の実施形態にかかる履歴型ダンパ30によれば、履歴型ダンパ1と同様の効果を奏する。また、凹部31と連結部5が嵌合することにより、変形の際に平板部3と連結部5との間にすべりが生じることがない。このため、同一荷重条件における平板部3の変形量が一定し、減衰性能が安定する。 Thus, according to the hysteresis type damper 30 concerning 2nd Embodiment, there exists an effect similar to the history type damper 1. FIG. Further, since the concave portion 31 and the connecting portion 5 are fitted, no slip occurs between the flat plate portion 3 and the connecting portion 5 at the time of deformation. For this reason, the deformation amount of the flat plate portion 3 under the same load condition is constant, and the damping performance is stabilized.

次に、第3の実施の形態に係る履歴型ダンパ40について説明する。図10は履歴型ダンパ40の側面図である。履歴型ダンパ40は、平板部3と連結部5とが溶接により接合される。溶接部41は、平板部3の対向面45と、連結部5の側面43との隅肉部に施される。なお、溶接方法は特定しないが、通常のアーク溶接で構わない。 Next, the hysteresis damper 40 according to the third embodiment will be described. FIG. 10 is a side view of the hysteresis damper 40. In the hysteresis damper 40, the flat plate portion 3 and the connecting portion 5 are joined by welding. The welded portion 41 is applied to the fillet portion between the facing surface 45 of the flat plate portion 3 and the side surface 43 of the connecting portion 5. The welding method is not specified, but normal arc welding may be used.

履歴型ダンパ40の接合部7を、履歴型ダンパ1と同様に構造体へ接合し、構造体から力を受けると、図3(b)における履歴型ダンパ1と同様に履歴型ダンパ40の変形部22が弾塑性変形し、エネルギーを吸収する。この際、連結部5は平板部3に溶接されている為、変形の際に連結部5と平板部3との間に相対するすべりが生じない。 When the joint 7 of the hysteretic damper 40 is joined to the structure in the same manner as the hysteretic damper 1 and receives a force from the structure, the hysteretic damper 40 is deformed in the same manner as the hysteretic damper 1 in FIG. The portion 22 is elastically plastically deformed and absorbs energy. At this time, since the connecting portion 5 is welded to the flat plate portion 3, no slip occurs between the connecting portion 5 and the flat plate portion 3 during deformation.

このように、第3の実施形態にかかる履歴型ダンパ40によれば、履歴型ダンパ1と同様の効果を奏する。また、平板部3の変形の際に平板部3と連結部5との間にすべりが生じることがないため、同一荷重条件における平板部3の変形量が一定し、減衰性能が安定する。更に、ボルト9、ナット11を使用しなくともよいため、部品点数を削減できる。 Thus, according to the hysteresis type damper 40 concerning 3rd Embodiment, there exists an effect similar to the history type damper 1. FIG. Further, since no slip occurs between the flat plate portion 3 and the connecting portion 5 when the flat plate portion 3 is deformed, the deformation amount of the flat plate portion 3 under the same load condition is constant, and the damping performance is stabilized. Furthermore, since it is not necessary to use the bolt 9 and the nut 11, the number of parts can be reduced.

次に、第4の実施の形態に係る履歴型ダンパ50について説明する。図11は、履歴型ダンパ50を示す図であり、図11(a)は、履歴型ダンパ50の連結部5側から見た図、図11(b)は履歴型ダンパ50の側面図である。履歴型ダンパ50の連結部5は、平板部3よりも幅広である。連結部5は、平板部3の幅方向両側に突出した状態で、平板部3の端部で挟まれ、溶接される。溶接部51は、平板部3の側面53と、平板部3の幅方向へ突出した連結部5の上下面55との隅肉部に施される。 Next, a hysteresis damper 50 according to the fourth embodiment will be described. FIG. 11 is a view showing the hysteresis damper 50, FIG. 11A is a view seen from the connecting portion 5 side of the hysteresis damper 50, and FIG. 11B is a side view of the hysteresis damper 50. . The connecting portion 5 of the hysteretic damper 50 is wider than the flat plate portion 3. The connecting portion 5 is sandwiched and welded between the end portions of the flat plate portion 3 in a state of projecting to both sides in the width direction of the flat plate portion 3. The welded portion 51 is applied to the fillet portion between the side surface 53 of the flat plate portion 3 and the upper and lower surfaces 55 of the connecting portion 5 protruding in the width direction of the flat plate portion 3.

履歴型ダンパ50の接合部7を、履歴型ダンパ1と同様に構造体へ接合し、構造体から力を受けると、図3(b)における履歴型ダンパ1と同様に履歴型ダンパ50の変形部22が弾塑性変形し、エネルギーを吸収する。この際、連結部5は平板部3に溶接されている為、変形の際に連結部5と平板部3との間に相対するすべりが生じない。 When the joint 7 of the hysteretic damper 50 is joined to the structure similarly to the hysteretic damper 1 and receives a force from the structure, the hysteretic damper 50 is deformed similarly to the hysteretic damper 1 in FIG. The portion 22 is elastically plastically deformed and absorbs energy. At this time, since the connecting portion 5 is welded to the flat plate portion 3, no slip occurs between the connecting portion 5 and the flat plate portion 3 during deformation.

また、連結部5の側面43との接触部近傍の平板部3の対向面45は変形部22に該当するため、この付近を溶接すると、熱影響により変形が安定しない恐れがある。しかし、履歴型ダンパ50の溶接部は、平板部3の側面53と、平板部3の幅方向へ突出した連結部5の上下面55であり、溶接部51が変形を伴わない部分である為、平板部3の変形部位は、溶接による影響を受けない。 In addition, since the facing surface 45 of the flat plate portion 3 in the vicinity of the contact portion with the side surface 43 of the connecting portion 5 corresponds to the deformed portion 22, if the vicinity is welded, the deformation may not be stabilized due to the influence of heat. However, the welded portion of the hysteretic damper 50 is the side surface 53 of the flat plate portion 3 and the upper and lower surfaces 55 of the connecting portion 5 protruding in the width direction of the flat plate portion 3, and the welded portion 51 is a portion that is not deformed. The deformed portion of the flat plate portion 3 is not affected by welding.

このように、第4の実施形態によれば、履歴型ダンパ50は、履歴型ダンパ1と同様の効果を奏する。また、履歴型ダンパ50の溶接部51が、平板部3の変形部22とは異なる部位であるため、変形部22は溶接による熱影響を受けることがない。このため、同一荷重条件における平板部3の変形量が一定し、減衰性能が安定する。 Thus, according to the fourth embodiment, the hysteresis damper 50 has the same effect as the hysteresis damper 1. Moreover, since the welding part 51 of the hysteresis type damper 50 is a different part from the deformation | transformation part 22 of the flat plate part 3, the deformation | transformation part 22 does not receive the heat influence by welding. For this reason, the deformation amount of the flat plate portion 3 under the same load condition is constant, and the damping performance is stabilized.

次に、第5の実施の形態に係る履歴型ダンパ60について説明する。図12は履歴型ダンパ60の側面図である。履歴型ダンパ60は、構造部材と接合するためのボルト61を具備している。ボルト61は、首下長さが平板部3同士の間隔よりも長く、ボルト頭部が平板部3の間に位置し、ボルト穴13へ挿入される。履歴型ダンパ60は、ボルト61をボルト穴13へ挿入した状態で、平板部3と連結部5とが溶接により接合される。したがって、ボルト61は、履歴型ダンパ60から抜け落ちない構造となっている。 Next, a hysteresis damper 60 according to a fifth embodiment will be described. FIG. 12 is a side view of the hysteresis damper 60. The hysteretic damper 60 includes a bolt 61 for joining with a structural member. The bolt 61 has a neck length that is longer than the interval between the flat plate portions 3, the bolt head portion is positioned between the flat plate portions 3, and is inserted into the bolt holes 13. In the hysteretic damper 60, the flat plate portion 3 and the connecting portion 5 are joined by welding in a state where the bolt 61 is inserted into the bolt hole 13. Therefore, the bolt 61 has a structure that does not fall off from the hysteresis damper 60.

履歴型ダンパ60の接合部7を、履歴型ダンパ1と同様に構造体へ接合し、構造体から力を受けると、図3(b)における履歴型ダンパ1と同様に履歴型ダンパ60の変形部22が弾塑性変形し、エネルギーを吸収する。 When the joint 7 of the hysteretic damper 60 is joined to the structure similar to the hysteretic damper 1 and a force is received from the structure, the hysteretic damper 60 is deformed in the same manner as the hysteretic damper 1 in FIG. The portion 22 is elastically plastically deformed and absorbs energy.

このように、第5の実施形態にかかる履歴型ダンパ60によれば、履歴型ダンパ1と同様の効果を奏する。また、履歴型ダンパ60と構造体とを取り付ける際に、ボルト61が予めボルト穴13に挿入されているため、狭い平板部3間でナット締結作業をする必要が無く、取り付け作業が簡便となる。 Thus, according to the hysteresis type damper 60 concerning 5th Embodiment, there exists an effect similar to the history type damper 1. FIG. Further, when attaching the hysteretic damper 60 and the structure, since the bolt 61 is inserted in the bolt hole 13 in advance, it is not necessary to perform a nut fastening operation between the narrow flat plate portions 3, and the mounting operation is simplified. .

次に、第6の実施の形態に係る履歴型ダンパ70について説明する。図13は、履歴型ダンパ70の斜視図である。履歴型ダンパ70は、角型の断面形状を成し、平板部3と連結部71とが一体で構成される。履歴型ダンパ70は、例えば、鍛造や板部材の曲げ加工により成形される。また、履歴型ダンパ70と同形状の断面を有する角鋼管等をスライス切断することでも得ることができる。 Next, a hysteresis damper 70 according to the sixth embodiment will be described. FIG. 13 is a perspective view of the hysteretic damper 70. The hysteretic damper 70 has a square cross-sectional shape, and the flat plate portion 3 and the connecting portion 71 are integrally formed. The hysteretic damper 70 is formed by, for example, forging or bending of a plate member. It can also be obtained by slicing a square steel pipe or the like having a cross section of the same shape as the hysteretic damper 70.

履歴型ダンパ70の接合部7を、履歴型ダンパ1と同様に構造体へ接合し、前記構造部材から力を受けると、図3(b)における履歴型ダンパ1と同様に履歴型ダンパ70の変形部22が弾塑性変形し、エネルギーを吸収する。 When the joint 7 of the hysteretic damper 70 is joined to the structure in the same manner as the hysteretic damper 1 and a force is received from the structural member, the hysteretic damper 70 of the hysteretic damper 70 is similar to the hysteretic damper 1 in FIG. The deformation part 22 is elastically plastically deformed and absorbs energy.

このように、第6の実施形態にかかる履歴型ダンパ70によれば、履歴型ダンパ1と同様の効果を奏する。また、履歴型ダンパ70の変形の際に、平板部3と連結部71との間にすべりが生じることがないため、同一荷重条件における平板部3の変形量が一定し、減衰性能が安定する。また、履歴型ダンパ70は、平板部3と連結部71とを接合する必要がないため、構造が簡易であり、ダンパ組み立てが容易である。 Thus, according to the hysteresis type damper 70 concerning 6th Embodiment, there exists an effect similar to the history type damper 1. FIG. Further, since no slip occurs between the flat plate portion 3 and the connecting portion 71 when the hysteretic damper 70 is deformed, the deformation amount of the flat plate portion 3 under the same load condition is constant, and the damping performance is stabilized. . Moreover, since the hysteresis type damper 70 does not need to join the flat plate part 3 and the connection part 71, its structure is simple and the damper assembly is easy.

次に、第7の実施の形態に係る履歴型ダンパ80について説明する。図14は、履歴型ダンパ80の斜視図である。履歴型ダンパ80は、平板部3と湾曲した連結部81とが一体で構成される。履歴型ダンパ80は、例えば、鍛造や板部材の曲げ加工により成形される。また、丸鋼管等をスライス切断し、鋼管を押しつぶして平板部3を形成しても良い。 Next, a hysteresis damper 80 according to a seventh embodiment will be described. FIG. 14 is a perspective view of the hysteresis damper 80. In the hysteresis damper 80, the flat plate portion 3 and the curved connecting portion 81 are integrally formed. The hysteretic damper 80 is formed by, for example, forging or bending of a plate member. Further, the flat plate portion 3 may be formed by slicing and cutting a round steel pipe or the like and crushing the steel pipe.

履歴型ダンパ80の接合部7を、履歴型ダンパ1と同様に構造体へ接合し、構造材から力を受けると、図3(b)における履歴型ダンパ1と同様に履歴型ダンパ80の変形部22が弾塑性変形し、エネルギーを吸収する。なお、この際、平板部3の平坦な部分のみが、弾塑性変形によりエネルギーを吸収する変形部22となり、湾曲した連結部81はほとんど弾性変形するため、エネルギーの吸収には寄与しない。 When the joint 7 of the hysteretic damper 80 is joined to the structure in the same manner as the hysteretic damper 1 and receives a force from the structural material, the hysteretic damper 80 is deformed in the same manner as the hysteretic damper 1 in FIG. The portion 22 is elastically plastically deformed and absorbs energy. At this time, only the flat portion of the flat plate portion 3 becomes the deformed portion 22 that absorbs energy by elasto-plastic deformation, and the curved connecting portion 81 is almost elastically deformed, so that it does not contribute to energy absorption.

このように、第7の実施形態にかかる履歴型ダンパ80によれば、履歴型ダンパ1と同様の効果を奏する。また、変形の際に、平板部3と連結部5との間にすべりが生じることがないため、同一荷重条件における平板部3の変形量が一定し、減衰性能が安定する。また、履歴型ダンパ80は、平板部3と連結部81とを接合する必要がないため、構造が簡易であり、ダンパ組み立てが容易である。 Thus, according to the history type damper 80 concerning 7th Embodiment, there exists an effect similar to the history type damper 1. FIG. Further, since no slip occurs between the flat plate portion 3 and the connecting portion 5 during the deformation, the deformation amount of the flat plate portion 3 under the same load condition is constant, and the damping performance is stabilized. Moreover, since the hysteresis type damper 80 does not need to join the flat plate part 3 and the connection part 81, its structure is simple and the damper assembly is easy.

以上、添付図を参照しながら、本発明の実施の形態を説明したが、本発明の技術的範囲は、前述した実施の形態に左右されない。当業者であれば、特許請求の範囲に記載された技術的思想の範疇内において各種の変更例または修正例に想到し得ることは明らかであり、それらについても当然に本発明の技術的範囲に属するものと了解される。 As mentioned above, although embodiment of this invention was described referring an accompanying drawing, the technical scope of this invention is not influenced by embodiment mentioned above. It is obvious for those skilled in the art that various modifications or modifications can be conceived within the scope of the technical idea described in the claims, and these are naturally within the technical scope of the present invention. It is understood that it belongs.

例えば、履歴型ダンパ60のように予めボルトを挿入する構成は、他の履歴型ダンパと組み合わせることも出来る。また、幅狭部24、あて板26および、熱処理部28は、履歴型ダンパ30〜80についても設けることができる。また、履歴型ダンパ1の構造体との取り付けは、接続部材を用いて、ボルト等で接合したが、構造体と履歴型ダンパを直接溶接というによって取り付けても良い。この場合、接合部7にはボルト穴13は不要である。 For example, the configuration in which the bolt is inserted in advance like the hysteresis type damper 60 can be combined with other history type dampers. Moreover, the narrow part 24, the cover plate 26, and the heat processing part 28 can be provided also about the hysteresis type dampers 30-80. In addition, the hysteresis damper 1 is attached to the structure using a connecting member and joined with a bolt or the like, but the structure and the hysteresis damper may be attached by direct welding. In this case, the bolt hole 13 is not necessary in the joint portion 7.
