Description

本発明は、接合金物を有する建築物に関し、詳しくは、対象物間の相対変位に伴って減衰部材が降伏して減衰効果を発揮する接合金物を有する建築物に関する。   The present invention relates to a building having a metal joint, and more particularly, to a building having a metal joint that exhibits a damping effect by yielding of a damping member with relative displacement between objects.
従来、ツーバイフォー構造や木質壁パネル構造、薄板軽量形鋼造などの枠組壁工法建築物において、木材や形鋼からなる枠組材に面材を固定した耐力壁が一般的に用いられている。そして、枠組壁工法建築物では、地震や風等により建築物に作用する水平力(外力)に対し、耐力壁の面材がせん断力として水平力を負担することで、建物全体としての水平耐力が確保されるようになっている。
ところで、耐力壁を用いた建築物では一般的に、最下層(1階)の耐力壁の壁脚部がホールダウン金物等を介して基礎のアンカーボルトに連結されており、水平力を負担した耐力壁がロッキングした際に、ホールダウン金物やアンカーボルトが破損しないように設計されている。すなわち、ホールダウン金物やアンカーボルトが破損してしまうと、ロッキングにより耐力壁が回転してしまって所定の水平力が負担できなくなり、建物全体としての水平耐力が低下するという不具合が生じてしまう。また逆に、耐力壁は比較的高い水平耐力が確保できるものの、水平剛性も高くなることから、地震による入力エネルギーが大きくなってしまい、より高い水平耐力が必要になるというデメリットもある。
2. Description of the Related Art Conventionally, in a frame wall construction method such as a two-by-four structure, a wooden wall panel structure, and a thin and light-weight steel structure, a load bearing wall in which a face material is fixed to a frame material made of wood or shape steel is generally used. And in framed wall construction buildings, the horizontal strength of the building as a whole is borne by the bearing material of the load bearing wall bearing the horizontal force as a shearing force against the horizontal force (external force) acting on the building due to earthquakes and winds. Is to be secured.
By the way, in a building using a load bearing wall, the wall legs of the load bearing wall in the lowermost layer (first floor) are generally connected to the anchor bolts of the foundation via hole-down hardware and bear the horizontal force. It is designed so that the hole-down hardware and anchor bolt are not damaged when the bearing wall is locked. That is, if the hole-down hardware or the anchor bolt is damaged, the load bearing wall rotates due to locking, and a predetermined horizontal force cannot be borne, resulting in a problem that the horizontal strength of the entire building is lowered. On the other hand, the bearing wall can secure a relatively high horizontal strength, but also has a disadvantage that the horizontal rigidity becomes high, so that the input energy due to the earthquake becomes large and a higher horizontal strength is required.
一方、耐力壁ではなく柱の柱脚部において、基礎(ベースプレート)と柱脚との間に曲げパネルやせん断パネルを設置し、入力エネルギーの低減を図った柱脚部の制震構造が提案されている(例えば、特許文献1参照)。
特許文献1に記載された制震構造では、曲げパネルやせん断パネルの一方側が溶接等によって柱脚部に接合され、他方側が取付プレート(支持プレート)を介してベースプレートに接合されている。そして、地震等により柱が浮き上がる方向の引張り力が作用した際に、曲げパネルが曲げ降伏したりせん断パネルがせん断降伏したりすることで、引張り力を吸収するように構成されている。
On the other hand, a seismic structure for the column base that reduces the input energy by installing a bending panel or shear panel between the foundation (base plate) and the column base at the column base instead of the bearing wall has been proposed. (For example, refer to Patent Document 1).
In the vibration control structure described in Patent Document 1, one side of a bending panel or a shear panel is joined to a column base by welding or the like, and the other side is joined to a base plate via a mounting plate (support plate). When the tensile force in the direction in which the column is lifted due to an earthquake or the like is applied, the bending panel is bent and yielded or the shearing panel is sheared and yielded, so that the tensile force is absorbed.
特開2004−92096号公報JP 2004-92096 A
しかしながら、前記特許文献1に記載の制震構造では、曲げパネルやせん断パネルを介して柱がベースプレートに連結され、柱とベースプレートとは接合されていないため、柱を立設する際の施工精度が確保しにくく、施工手間も増大してしまう。さらに、曲げパネルやせん断パネルを柱脚部に直接接合しているため、これらのパネルを地震後に取り換えたり、より高性能のものに交換したりなどができず、メンテナンス性が劣るという問題もある。また、特許文献1に記載の制震構造では、柱脚部の周辺に曲げパネルやせん断パネルを配置するための広いスペースが必要となるため、枠組壁工法建築物における耐力壁の壁脚部に利用することが困難である。さらに、耐力壁の壁脚部に利用したとして、壁脚部の片側に特許文献1のようなパネルを接合すると、壁脚部にパネルからの反力が作用してしまうため、壁脚部が破損したり壁脚部の補強が必要になるなど、耐震性能の低下やコスト増加の原因ともなる。   However, in the vibration control structure described in Patent Document 1, since the column is connected to the base plate via a bending panel or a shear panel, and the column and the base plate are not joined, the construction accuracy when the column is erected is high. It is difficult to secure, and the construction labor will increase. In addition, since bent panels and shear panels are joined directly to the column base, these panels cannot be replaced after an earthquake or replaced with higher performance ones, resulting in poor maintenance. . In addition, in the vibration control structure described in Patent Document 1, a large space is required for arranging bent panels and shear panels around the column base, so that the wall base of the load-bearing wall in the frame wall construction method It is difficult to use. Furthermore, since it used for the wall leg part of a load bearing wall, when a panel like patent document 1 is joined to one side of a wall leg part, since the reaction force from a panel will act on a wall leg part, It may cause damage and / or cost increase due to damage and / or reinforcement of wall legs.
本発明の目的は、地震等のエネルギーを効果的に吸収できる接合金物を有する建築物を提供することにある。   An object of the present invention is to provide a building having a metal joint that can effectively absorb energy such as an earthquake.

すなわち、耐力壁10の一方側から水平力が作用した場合には、一方側の縦の枠組材11下端部が基礎2から浮き上がるように耐力壁10がロッキングし、一方側の枠組材11に取り付けた接合金物20がアンカーボルト6に引っ張られることで変形し、減衰効果を発揮するようになっている。この際、他方側の縦の枠組材11下端部は、基礎2の上面に載置されているために移動量が極めて小さく、他方側の枠組材11に取り付けた接合金物20には変形が生じないようになっている。   That is, when a horizontal force is applied from one side of the bearing wall 10, the bearing wall 10 is locked so that the lower end of the vertical frame member 11 on one side is lifted from the foundation 2, and is attached to the frame member 11 on one side. The joint metal 20 is deformed by being pulled by the anchor bolt 6 and exhibits a damping effect. At this time, the lower end of the vertical frame member 11 on the other side is placed on the upper surface of the foundation 2, so that the amount of movement is extremely small, and the joint hardware 20 attached to the frame member 11 on the other side is deformed. There is no such thing.
次に、接合金物20について、図4および図5に基づいて詳しく説明する。
図4は、接合金物20およびアンカーボルト6を示す斜視図である。図5は、接合金物20の変形状態を示す側面図である。

鋼材22,23で形成された四周枠状のフレーム24を備えて構成されている。また、上部補強用鋼材22および下部補強用鋼材23の略中央には、アンカーボルト6を挿通させるための挿通孔22A,23Aが形成されている。
Next, the metal joint 20 will be described in detail based on FIG. 4 and FIG.
FIG. 4 is a perspective view showing the joint hardware 20 and the anchor bolt 6. FIG. 5 is a side view showing a deformed state of the metal joint 20.
In FIG. 4 and FIG. 5, the metal joint 20 extends over the wall connecting steel plates 21 as a pair of wall connecting portions connected to the flange 14 of the frame member 11 and the upper portions of the pair of wall connecting steel plates 21. An upper reinforcing steel member 22 to be joined and a lower reinforcing steel member 23 to be joined across the lower portions of the pair of wall connecting steel plates 21 are provided. These wall connecting steel plates 21, upper and lower reinforcing steel members 22 are provided. , 23 and a frame 24 having a quadrilateral frame shape. Further, insertion holes 22 </ b> A and 23 </ b> A for inserting the anchor bolts 6 are formed in the approximate center of the upper reinforcing steel material 22 and the lower reinforcing steel material 23.
接合金物20のフレーム24内部には、一対の壁連結用鋼板21間に渡って設けられる上下のフランジ板25と、一対の壁連結用鋼板21間の中央位置にて上下のフランジ板25を連結する筒状鋼材26と、筒状鋼材26の左右から径方向に延びる減衰部材としてのダンパー用鋼板27とが設けられている。上下のフランジ板25は、壁連結用鋼板21に溶接接合され、これらのフランジ板25の中央部には、アンカーボルト6を挿通させるための挿通孔が形成されている。筒状鋼材26は、アンカーボルト6に連結されるアンカー連結部であって、その中空内部にアンカーボルト6を挿通した状態で、上下のフランジ板25の上下からナット28を締め付けることで、アンカーボルト6が連結されるようになっている。   The upper and lower flange plates 25 provided between the pair of wall connecting steel plates 21 and the upper and lower flange plates 25 are connected to each other at the center position between the pair of wall connecting steel plates 21 inside the frame 24 of the joint hardware 20. And a damper steel plate 27 as a damping member extending in the radial direction from the left and right of the cylindrical steel material 26 is provided. The upper and lower flange plates 25 are welded to the wall-connecting steel plate 21, and an insertion hole for inserting the anchor bolt 6 is formed in the center of these flange plates 25. The tubular steel member 26 is an anchor connecting portion connected to the anchor bolt 6, and the anchor bolt is tightened from above and below the upper and lower flange plates 25 in a state where the anchor bolt 6 is inserted into the hollow interior. 6 are connected.
一対のダンパー用鋼板27は、矩形状の鋼板から構成され、それぞれ外側の側端縁が壁連結用鋼板21の内面に溶接接合され、内側の側端縁が筒状鋼材26の周面に溶接接合され、上下端縁が上下のフランジ板25に溶接接合されている。そして、一対のダンパー用鋼板27は、アンカーボルト6の軸線に対して略線対称に配置されている。このような接合金物20は、図5に示すように、耐力壁10がロッキングして枠組材11が浮き上がった際に、枠組材11とともにフレーム24が上方に移動し、アンカーボルト6によって筒状鋼材26が下方に引っ張られることで、一対のダンパー用鋼板27がせん断変形する。そして、せん断変形したダンパー用鋼板27が所定のせん断耐力でせん断降伏し、このようなせん断変形−耐力関係の所定の履歴ループを描いて繰り返し変形することで、エネルギーを吸収するようになっている。すなわち、ダンパー用鋼板27の履歴吸収エネルギーに応じた減衰効果(履歴減衰)が発揮されるようになっている。   The pair of damper steel plates 27 is formed of a rectangular steel plate, the outer side edges are welded to the inner surface of the wall connecting steel plate 21, and the inner side edges are welded to the peripheral surface of the tubular steel material 26. The upper and lower edges are welded and joined to the upper and lower flange plates 25. The pair of damper steel plates 27 are disposed substantially symmetrically with respect to the axis of the anchor bolt 6. As shown in FIG. 5, when the bearing wall 10 is locked and the frame member 11 is lifted up, the frame 24 moves upward together with the frame member 11. By pulling 26 downward, the pair of damper steel plates 27 undergoes shear deformation. Then, the damper-deformed steel plate 27 for shear deformation yields with a predetermined shear strength, and draws a predetermined hysteresis loop of such a shear deformation-proof strength relationship to repeatedly deform, thereby absorbing energy. . That is, the damping effect (history damping) according to the hysteresis absorbed energy of the damper steel plate 27 is exhibited.
なお、耐力壁10に取り付ける接合金物としては、前述の構成に限らず、以下の図6および図7に示す接合金物30,40のような構成であってもよい。
図6および図7は、それぞれ本参考形態の変形例に係る接合金物20,30を示す斜視図および分解斜視図である。

Is provided. The tubular steel member 36 is an anchor connecting portion connected to the anchor bolt 6 so that the anchor bolt 6 is connected by tightening a nut from above and below in a state where the anchor bolt 6 is inserted into the hollow interior. It has become. Further, the damper steel plate 37 is formed in a substantially U-shaped cross section, and both ends thereof are welded (flared) to the wall connecting steel plate 31 and welded to the tubular steel member 36 via the slit 37A in the center. Joined (slot welding). That is, the damper steel plates 37 are joined by extending in a tangential direction along the peripheral surface of the cylindrical steel material 36, and two damper steel plates 37 are arranged between each of the pair of wall connecting steel plates 31 and the cylindrical steel material 36. Will be.
一方、図7に示す接合金物40は、前記フレーム24,34を備えず、アンカー連結部として上下一対で設けられる上端縁連結部材45および下端縁連結部材46と、前後一対で互いに対向して略平行に延びる2枚のダンパー用鋼板47とを有して構成されている。上端縁連結部材45および下端縁連結部材46は、2枚のダンパー用鋼板47の上端縁同
士および下端縁同士をそれぞれ連結するもので、アンカーボルト6を挿通させるための挿通孔45A,46Aを備えている。
On the other hand, the metal fitting 40 shown in FIG. 7 does not include the frames 24 and 34, and the upper and lower edge connecting members 45 and 46 provided as a pair of upper and lower anchors as the anchor connecting portions are substantially opposed to each other in a pair of front and rear. It is configured to have two damper steel plates 47 extending in parallel. The upper end edge connecting member 45 and the lower end edge connecting member 46 connect the upper end edges and the lower end edges of the two damper steel plates 47, respectively, and include insertion holes 45A and 46A for allowing the anchor bolts 6 to pass therethrough. ing.
そして、上端縁連結部材45および下端縁連結部材46には、上下からナット48を締め付けることで、アンカーボルト6が連結されるとともに、左右両端部に折り曲げ形成された固定片部45B,46Bを介して枠組材11のフランジ14にボルト接合されるようになっている。また、ダンパー用鋼板47は、断面略コ字形に形成され、その両端部に折り曲げ形成された固定片部47Aが、上端縁連結部材45および下端縁連結部材46の固定片部45B,46Bとともに、枠組材11のフランジ14にボルト接合されるようになっている。すなわち、固定片部45B,46Bおよび固定片部47Aによって、接合金物40における壁連結部が構成されている。   The upper end edge connecting member 45 and the lower end edge connecting member 46 are tightened with nuts 48 from above and below to connect the anchor bolts 6 and through fixed pieces 45B and 46B which are bent at both left and right ends. Thus, the bolt is joined to the flange 14 of the frame assembly 11. Further, the damper steel plate 47 is formed in a substantially U-shaped cross section, and the fixed piece portions 47A bent at both end portions thereof, together with the fixed piece portions 45B and 46B of the upper edge connecting member 45 and the lower edge connecting member 46, It is bolted to the flange 14 of the frame member 11. In other words, the fixed piece portions 45B and 46B and the fixed piece portion 47A constitute a wall connecting portion in the metal joint 40.

The damper steel plate 47 includes a fixed piece portion 47A and ribs 47B. A plate-like portion located between the two is shear-deformed and exhibits a damping effect.
以上の参考形態によれば、次に示すような各種作用効果が得られる。
すなわち、枠組壁工法建築物1において、耐力壁10の壁脚部に建物基礎2と連結される接合金物20,30,40を設置したことで、地震等の水平力が建築物1に作用した際に、耐力壁10がロッキングして接合金物20,30,40のダンパー用鋼板27,37,47が変形することにより減衰効果が発揮される。従って、接合金物20,30,40の減衰効果に応じたエネルギー吸収を行うことで、建築物1の振動を抑制することができ、耐震性能を向上させることができる。そして、耐力壁10において所定のせん断力を負担した状態でのロッキングに対して、ダンパー用鋼板27,37,47がせん断降伏するような設定にしておくことで、耐力壁10の負担せん断力が過大にならず、かつダンパー用鋼板27,37,47の降伏によって建築物1の振動周期が長周期化することから、地震の入力エネルギー自体を抑制することができ、経済的な建築物1の設計が可能になる。
According to the above reference embodiment, the following various effects can be obtained.
That is, in the frame wall construction method building 1, horizontal forces such as earthquakes acted on the building 1 by installing the joint hardware 20, 30, 40 connected to the building foundation 2 on the wall leg portion of the load bearing wall 10. At this time, the load-bearing wall 10 is locked, and the damper steel plates 27, 37, and 47 of the metal joints 20, 30, and 40 are deformed, so that a damping effect is exhibited. Therefore, the vibration of the building 1 can be suppressed and the seismic performance can be improved by absorbing energy according to the damping effect of the joint hardware 20, 30, 40. And by setting so that the steel plates 27, 37, and 47 for the damper are shear-yield with respect to the rocking in a state where a predetermined shear force is borne in the load bearing wall 10, the load shear force of the load bearing wall 10 is reduced. Since the vibration period of the building 1 becomes longer due to the yielding of the damper steel plates 27, 37, and 47, the input energy of the earthquake itself can be suppressed, and the economic building 1 Design becomes possible.
また、接合金物20,30,40において、壁連結部(壁連結用鋼板21,31、固定片部45B,46B,47A)が左右一対で配置され、減衰部材(ダンパー用鋼板27,37,47)がアンカーボルト6の軸線に対して略線対称に配置されることで、減衰効果を発揮する際の偏心による付加応力の発生が防止できる。従って、耐力壁10の壁脚部(枠組材11)に作用する偏心曲げモーメント等の付加応力に対する補強等が不要、あるいは最小限の補強とすることができ、耐力壁10の製造コストの増加が防止できる。さらに、付加応力が生じないことで、接合金物20,30,40を介したアンカーボルト6と耐力壁10との間の力の伝達がスムーズになり、ダンパー用鋼板27,37,47における力学的メカニズムが明確になって、減衰効果が確実かつ適切に発揮され、地震等による振動エネルギーを効果的に吸収することができる。   In addition, in the joint hardware 20, 30, 40, wall connecting portions (wall connecting steel plates 21, 31, fixing pieces 45 B, 46 B, 47 A) are arranged in a pair of left and right, and damping members (damper steel plates 27, 37, 47). ) Are arranged substantially symmetrically with respect to the axis of the anchor bolt 6, it is possible to prevent generation of additional stress due to eccentricity when exhibiting a damping effect. Accordingly, it is possible to eliminate or minimize reinforcement against additional stress such as an eccentric bending moment acting on the wall legs (frame member 11) of the load bearing wall 10, and increase the manufacturing cost of the load bearing wall 10. Can be prevented. Further, since no additional stress is generated, the force transmission between the anchor bolt 6 and the load bearing wall 10 via the joint hardware 20, 30, 40 becomes smooth, and the mechanical strength of the damper steel plates 27, 37, 47 is increased. The mechanism becomes clear, the damping effect is exhibited reliably and appropriately, and vibration energy due to earthquakes and the like can be absorbed effectively.
さらに、壁連結部(壁連結用鋼板21,31、固定片部45B,46B,47A)を耐力壁10の枠組材11に連結し、アンカー連結部(筒状鋼材26,36、上端縁連結部材45および下端縁連結部材46)をアンカーボルト6に連結することで、接合金物20,30,40を介して耐力壁10と建物基礎2とが連結されるので、耐力壁10や建物基礎2に通常の構造を用いることができる。そして、接合金物20,30,40内にダンパー用鋼板27,37,47が配置されているので、ダンパー用鋼板27,37,47自体を直接に耐力壁10に溶接する必要がないため、耐力壁10や接合金物20,30,40の
製造や設置作業が容易にできて、施工性を向上させることができる。さらに、接合金物20,30,40を耐力壁10から取り外すことも容易にでき、地震後の点検や交換などのメンテナンス性を向上させることができる。
Further, the wall connecting portions (wall connecting steel plates 21, 31 and fixed pieces 45B, 46B, 47A) are connected to the frame member 11 of the load bearing wall 10, and the anchor connecting portions (tubular steel members 26, 36, upper edge connecting members). 45 and the lower edge connecting member 46) are connected to the anchor bolt 6 so that the load bearing wall 10 and the building foundation 2 are connected to each other through the joint hardware 20, 30, 40. A normal structure can be used. Since the damper steel plates 27, 37, 47 are arranged in the joint hardware 20, 30, 40, it is not necessary to weld the damper steel plates 27, 37, 47 themselves directly to the load bearing wall 10. Manufacture and installation of the wall 10 and the joint hardware 20, 30, 40 can be facilitated, and workability can be improved. Furthermore, it is possible to easily remove the metal fittings 20, 30, and 40 from the bearing wall 10, and to improve maintenance such as inspection and replacement after the earthquake.
また、接合金物20,30において、一対の壁連結用鋼板21,31を上部補強用鋼材22,32および下部補強用鋼材23,33で連結してフレーム24,34を形成し、その内部にダンパー用鋼板27,37および筒状鋼材26,36を配置したことで、ダンパー用鋼板27,37からの減衰効果が壁連結用鋼板21,31に作用した際に、壁連結用鋼板21,31の変形等を防止することができる。さらに、上部補強用鋼材22,32および下部補強用鋼材23,33に形成した挿通孔22A,23A,32A,33Aにアンカーボルト6を挿通することで、アンカーボルト6とフレーム24,34との偏心をなくすことができ、偏心による付加応力の発生を防止することができ、ダンパー用鋼板27,37の減衰効果を適切に耐力壁10および建物基礎2に伝達することができる。   Further, in the metal joints 20 and 30, a pair of wall connecting steel plates 21 and 31 are connected by upper reinforcing steel materials 22 and 32 and lower reinforcing steel materials 23 and 33 to form frames 24 and 34, and dampers are formed therein. When the steel plates 27 and 37 and the tubular steel materials 26 and 36 are disposed, when the damping effect from the damper steel plates 27 and 37 acts on the wall connecting steel plates 21 and 31, the wall connecting steel plates 21 and 31 Deformation and the like can be prevented. Further, by inserting the anchor bolt 6 into the insertion holes 22A, 23A, 32A, 33A formed in the upper reinforcing steel materials 22, 32 and the lower reinforcing steel materials 23, 33, the anchor bolt 6 and the frames 24, 34 are eccentric. The generation of additional stress due to eccentricity can be prevented, and the damping effect of the damper steel plates 27 and 37 can be appropriately transmitted to the bearing wall 10 and the building foundation 2.
