Description

本発明は、パネル工法の木造建築物に制震を目的として取り付けられる木造用制震フレームと、その木造用制震フレームを木造建築物に取り付けるための取付構造とに関する。   BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a wooden vibration control frame mounted for the purpose of damping a wooden structure with a panel construction method, and a mounting structure for mounting the wooden vibration control frame to a wooden structure.

軸組の木造建築物において、高い耐震性を得るために、土台と梁、柱との間に形成された矩形空間に、当該空間に嵌合する外枠と、その外枠内に架設される筋交いとからなる耐力パネルを組み付けるパネル工法が知られている(例えば特許文献1)。このパネル工法は、耐力パネルを予め工場で製造しておき、建築現場で軸組内に取り付けることで施工されるため、品質管理や施工が容易で工期が短縮できる利点がある。   In the framed wooden building, in order to obtain high seismic resistance, it is constructed in the rectangular space formed between the base, the beam and the pillar, the outer frame fitted in the space, and the outer frame A panel construction method is known in which a load-bearing panel consisting of braces is assembled (for example, Patent Document 1). This panel construction method is constructed by manufacturing a load-bearing panel in a factory in advance and attaching it to a shaft assembly at a construction site, so there is an advantage that quality control and construction are easy and the construction period can be shortened.

特開2002−106067号公報JP, 2002-106067, A

このようなパネル工法においても、耐力パネル内に粘弾性ダンパー等の制震ダンパーを組み込んで制震フレームとして機能させる試みがある。例えば制震ダンパーがブレース状に組み込まれる制震フレームの場合、制震ダンパーの両端長手方向に延長木材等の取付部材を接合した制震ブレースを、ブラケットを介してフレームに接合して制震フレームを予め製造することになるが、この制震フレームでは、施工現場でフレームを軸組内に取り付けることはできても、フレーム内の制震ブレースを土台や柱等の軸組に連結することができないため、軸組の変形に伴う軸方向力が制震ブレースに十分に伝わらず、効果的な制震作用が得られない。従って、パネル工法への適用は難しく、制震ブレースを直接軸組に取り付ける施工にとどまっていた。   Also in such a panel construction method, there is an attempt to incorporate a damping damper such as a visco-elastic damper into a load-bearing panel to function as a damping frame. For example, in the case of a vibration control frame in which the vibration control damper is incorporated in a brace shape, the vibration control frame is formed by joining a vibration control brace including mounting members such as extension wood in the longitudinal direction of both ends of the vibration control damper In this seismic control frame, although it is possible to mount the frame in the framework at the construction site, it is possible to connect the seismic control brace in the frame to the foundation such as the base or pillars. Because the axial force resulting from the deformation of the shaft is not sufficiently transmitted to the seismic control brace, an effective seismic control action can not be obtained. Therefore, application to the panel construction method is difficult, and it has been limited to the construction in which the vibration control brace is directly attached to the shaft assembly.

そこで、本発明は、パネル工法に適用できて必要な制震作用が得られる木造用制震フレームと、その木造用制震フレームを木造建築物に取り付けるための取付構造とを提供することを目的としたものである。   Therefore, the present invention aims to provide a wooden vibration control frame which can be applied to a panel construction method to obtain necessary vibration control action, and a mounting structure for mounting the wooden vibration control frame to a wooden building.

Hereinafter, embodiments of the present invention will be described based on the drawings.
[Form 1]
FIG. 1 is a front view showing an example of a wooden vibration control frame (hereinafter simply referred to as "vibration control frame"). The vibration control frame 1 is composed of a vertically elongated rectangular frame 2 fitted in a framework of a wooden building, and a vibration control brace 3 diagonally installed in the frame 2. The frame 2 is formed by a pair of left and right vertical frames 4, 4 and a pair of upper and lower horizontal frames 5, 5 whose both ends are joined to the upper and lower ends of the vertical frames 4, 4 The reinforcement frames 6 and 6 parallel to the vertical frame 4 are joined to each other.
The vibration control brace 3 is formed by joining extension woods 8 and 8 as mounting members at both ends in the longitudinal direction of the viscoelastic damper 7 as a vibration control damper. The visco-elastic damper 7 is obtained by coaxially partially polymerizing the cylindrical outer tube 9 and the inner tube 10 and bonding a visco-elastic body (not shown) between the two tubes 9 and 10. A joint 11 extended to the end is joined to one extension wood 8, and the end of the inner pipe 10 and the other extension wood 8 are joined by a joint fitting 12.

そして、各延長木材8は、積層材で形成されて、ブラケット金具13を介してフレーム2のコーナー部(縦枠4と横枠5との仕口部)に接合される。このブラケット金具13は、図2に示すように、矩形状のダンパー固定部14と、ダンパー固定部14の長辺と短辺とからそれぞれ直角に折曲される第1取付部15及び第2取付部16とからなり、ダンパー固定部14には、延長木材8が配設される傾斜方向に沿って複数のビス孔17,17・・が形成されている。   Each extension wood 8 is formed of a laminated material, and is joined to the corner portion of the frame 2 (the connection portion between the vertical frame 4 and the horizontal frame 5) through the bracket 13. As shown in FIG. 2, the bracket fitting 13 includes first and second attachment portions 15 and 2 that are bent at a right angle from the long and short sides of the rectangular damper fixing portion 14 and the damper fixing portion 14, respectively. A plurality of screw holes 17, 17... Are formed in the damper fixing portion 14 along the inclination direction in which the extension wood 8 is disposed.

このビス孔は、第1取付部15と第2取付部16とにおいても形成されるが、ここでは端部側の本固定部S1と、ダンパー固定部14側の仮固定部S2とに領域が分けられて、本固定部S1に本固定用ビス孔18,18・・が、仮固定部S2に仮固定用ビス孔19,19・・がそれぞれ形成されている。この本固定部S1は、ダンパー固定部14の内面側に接合された延長木材8を第1取付部15及び第2取付部16に投影させた場合に、投影部分の外側に露出する領域で、仮固定部S2は、投影部分内に収まる領域となっている。また、第1、第2取付部15,16において、本固定用ビス孔18の数は、仮固定用ビス孔19の数よりも多く形成されている。   Although this screw hole is also formed in the first attachment portion 15 and the second attachment portion 16, here, there is a region between the main fixing portion S1 on the end side and the temporary fixing portion S2 on the damper fixing portion 14 side. .. Are separately formed in the main fixing portion S1, and screw holes 19, 19... For temporary fixing are formed in the temporary fixing portion S2. The main fixing portion S1 is an area exposed to the outside of the projected portion when the extended wood 8 joined to the inner surface side of the damper fixing portion 14 is projected onto the first mounting portion 15 and the second mounting portion 16. The temporary fixing portion S2 is an area that fits within the projection portion. Further, in the first and second attachment portions 15 and 16, the number of the permanent fixing screw holes 18 is larger than the number of the temporary fixing screw holes 19.

以上の如く構成された制震フレーム1は、工場等で予め製造することができる。まずフレーム2を作製した後、制震ブレース3が架設される対角線上の仕口部において、ブラケット金具13,13をそれぞれ取り付ける。このとき、図4に示すように各ブラケット金具13のダンパー固定部14の外面がフレーム2の厚み方向の端面と一致する位置で、第1取付部15の仮固定部S2を、仮固定用ビス孔19,19・・を用いてフレーム2の縦枠4に仮固定用ビス20,20によって固定し、第2取付部16の仮固定部S2を、仮固定用ビス孔19,19・・を用いてフレーム2の横枠5に仮固定用ビス20,20・・によって固定する。   The vibration control frame 1 configured as described above can be manufactured in advance in a factory or the like. First, after the frame 2 is manufactured, the bracket fittings 13 and 13 are attached to the diagonal connection at which the vibration control brace 3 is installed. At this time, as shown in FIG. 4, the temporary fixing portion S2 of the first mounting portion 15 is used as a screw for temporary fixing at a position where the outer surface of the damper fixing portion 14 of each bracket 13 coincides with the end face of the frame 2 in the thickness direction. Using the holes 19, 19 · · · fixed to the vertical frame 4 of the frame 2 with the temporary fixing screws 20, 20, the temporary fixing portion S 2 of the second mounting portion 16 It fixes to the horizontal frame 5 of the flame | frame 2 by bis | screws 20 and 20 ... for temporary fixing.

こうして対角線上の仕口部に取り付けたブラケット金具13,13の間に、制震ブレース3を掛け渡して、各延長木材8の先端部を、各ブラケット金具13のダンパー固定部14の内面に、ビス孔17,17・・を用いてビス21,21・・によって固定する。最後に補強枠6,6を、制震ブレース3の架設側と反対側の端面からフレーム2内に取り付けると、フレーム2内に制震ブレース3が架設された制震フレーム1が得られる。この状態で各ブラケット金具13の第1、第2取付部15,16の本固定部S1は、延長木材8に隠されることなく露出している。   In this way, the vibration control brace 3 is bridged between the bracket fittings 13 and 13 attached to the diagonal connection parts, and the tip of each extension wood 8 is placed on the inner surface of the damper fixing part 14 of each bracket fitting 13 Using the screw holes 17, 17 ···, fix the screws 21 · 21 · · ·. Finally, when the reinforcing frames 6, 6 are attached to the frame 2 from the end face opposite to the installation side of the seismic control brace 3, a seismic control frame 1 in which the seismic control brace 3 is installed in the frame 2 is obtained. In this state, the main fixing portions S1 of the first and second mounting portions 15 and 16 of the bracket 13 are exposed without being hidden by the extension wood 8.

この制震フレーム1を木造建築物の施工現場で軸組に取り付ける場合は、図3,4に示すように、左右の柱31,31及び上下の梁32、土台33で形成される軸組30内にフレーム2を嵌め込み、各ブラケット金具13の第1取付部15における本固定部S1を、本固定用ビス孔18,18・・を用いて仮固定用ビス20よりも長い本固定用ビス34,34・・により、縦枠4を介して柱31までねじ込むことで固定する。そして、第2取付部16における本固定部S1も、本固定用ビス孔18,18・・を用いて横枠5を介して上側のブラケット金具13では梁32まで、下側のブラケット金具13では土台33まで本固定用ビス34,34・・をねじ込むことで固定する。すると、フレーム2が本固定用ビス34,34・・によって軸組30内に固定されると共に、制震ブレース3の延長木材8,8がブラケット金具13,13を介して軸組30に固定される。
よって、地震等によって軸組30が加振されると、水平方向の変位が制震ブレース3に伝わって軸方向に圧縮力と引張力とを交互に作用させるため、粘弾性ダンパー7の粘弾性体が剪断変形を生じさせて振動エネルギーを熱エネルギーに変換し、減衰作用を生じさせる。
When this vibration control frame 1 is attached to a framework at a construction site of a wooden building, as shown in FIGS. 3 and 4, a framework 30 formed by left and right columns 31, 31 and upper and lower beams 32, The frame 2 is fitted inside, and the main fixing portion S1 of the first mounting portion 15 of each bracket 13 is longer than the temporary fixing screw 20 by using the final fixing screw holes 18, 18 ···. , 34 · · · fixed by screwing to the column 31 through the vertical frame 4. Then, the main fixing portion S1 in the second mounting portion 16 is also to the beam 32 in the upper side bracket fitting 13 via the horizontal frame 5 using the final fixing screw holes 18, 18 ··· and the lower side bracket fitting 13 Fixing screws 34, 34 · · · for fixing to the base 33 by screwing. Then, the frame 2 is fixed in the shaft assembly 30 by the fixing screws 34, 34, ..., and the extension woods 8, 8 of the vibration control brace 3 are fixed to the shaft assembly 30 via the bracket fittings 13, 13. Ru.
Therefore, when the shaft 30 is excited by an earthquake or the like, the displacement in the horizontal direction is transmitted to the vibration control brace 3 to alternately exert the compressive force and the tensile force in the axial direction. The body shears to convert vibrational energy into thermal energy and produce a damping effect.

このように、上記形態1の制震フレーム1及びその取付構造によれば、軸組30内に嵌合固定される木製のフレーム2と、フレーム2内に配置される粘弾性ダンパー7と、粘弾性ダンパー7が延長木材8,8を介して間接的に固定されるダンパー固定部14、軸組30への本固定部S1、フレーム2への仮固定部S2を備えたブラケット金具13,13と、を含む制震フレーム1を予め製造して、ブラケット金具13を、ダンパー固定部14に延長木材8を固定した状態で、仮固定部S2を介してフレーム2に仮固定し、本固定部S1をフレーム2を介して軸組30に本固定するようにしたことで、予め製造した制震フレーム1を施工現場で軸組30に取り付けるパネル工法にも適用可能となり、必要な制震作用が得られる。よって、品質管理や施工が容易で工期が短縮できるというパネル工法による利点も享受できる。   As described above, according to the vibration control frame 1 of the first aspect and the mounting structure thereof, the wooden frame 2 fitted and fixed in the shaft set 30, the visco-elastic damper 7 disposed in the frame 2, and the viscosity A damper fixing portion 14 in which the elastic damper 7 is indirectly fixed via the extension woods 8 and 8, a main fixing portion S1 to the shaft assembly 30, and bracket fittings 13 and 13 having a temporary fixing portion S2 to the frame 2 , The bracket fitting 13 is temporarily fixed to the frame 2 via the temporary fixing portion S2 in a state where the extension wood 8 is fixed to the damper fixing portion 14, and the main fixing portion S1 is manufactured. By fixing the main frame 30 to the main frame 30 via the frame 2, it becomes possible to apply to a panel construction method in which the seismic control frame 1 manufactured in advance is attached to the main frame 30 at the construction site. Be Therefore, it is possible to enjoy the advantage of the panel method that quality control and construction are easy and the construction period can be shortened.

特にここでは、ブラケット金具13の本固定部S1と仮固定部S2とはそれぞれ別々に形成されるので、本固定部S1と仮固定部S2とを容易に区別でき、仮固定と本固定とに係る作業がやりやすくなる。
また、本固定部S1の本固定用ビス孔18の数を、仮固定部S2の仮固定用ビス孔19の数よりも多くしているので、作業者には本固定部S1と仮固定部S2との区別がよりしやすくなる上、本固定に必要な取付強度も確保できる。
Particularly in this case, since the main fixing portion S1 and the temporary fixing portion S2 of the bracket 13 are separately formed, the main fixing portion S1 and the temporary fixing portion S2 can be easily distinguished, and the temporary fixing and the final fixing can be performed. It becomes easy to do the work.
Further, since the number of main fixing screw holes 18 of the main fixing portion S1 is larger than the number of temporary fixing screw holes 19 of the temporary fixing portion S2, for the operator, the main fixing portion S1 and the temporary fixing portion This makes it easier to distinguish from S2, and also secures the mounting strength required for the final fixing.

なお、形態1において、ダンパー固定部のビス孔の数と、第1、第2取付部の本固定用ビス孔及び仮固定用ビス孔の数とは、上記形態に限らず、適宜増減可能である。但し、これらのビス孔は全て用いる必要はなく、一部を選択してビスをねじ込むようにしても差し支えない。
また、ダンパー固定部や第1、第2取付部の形状も、例えばダンパー固定部を矩形状以外に延長木材の接合方向へ突出する台形状としたり、正方形状や扇状としたり、第1、第2取付部をダンパー固定部よりも長く形成したり等、適宜変更可能である。
さらに、上記形態では、仮固定、本固定共にビスによる固定としているが、例えば仮固定を釘打ちとして本固定をビスとする等、仮固定と本固定とで固定手段を変えることもできる。

Next, another embodiment of the present invention will be described. However, the same components as in the first embodiment are assigned the same reference numerals and redundant explanations are omitted.
[Form 2]
Also in the vibration control frame 1A shown in FIG. 5, the vibration control brace 3 is attached to the connection portion of the frame 2 via the bracket fittings 40, 40. As shown in FIG. 6, the bracket 40 includes the damper fixing portion 41, the first attachment portion 42, and the second attachment portion 43 as in the first embodiment, but the first and second attachment portions 42 are provided. , 43 is formed to be approximately half the thickness of the frame 2 and lower than that in the first embodiment. Further, in the first and second attachment portions 42 and 43 here, the division of the main fixing portion S1 and the temporary fixing portion S2 is not divided, and a plurality of screw holes 44, 44 ··· are formed at random. Are partially selectable for permanent fixing, and the remaining temporarily fixed for temporary fixing. In other words, the first and second attachment portions 42 and 43 serve as dual purpose fixing portions that are shared by the main fixing portion S1 and the temporary fixing portion S2 in the same area.

以上の如く構成された制震フレーム1Aも、工場等で予め製造する場合、作製したフレーム2の対角線上の仕口部において、ブラケット金具40,40をそれぞれ取り付ける。このとき、図8に示すように各ブラケット金具40のダンパー固定部41がフレーム2の厚み方向の中央となるように片側へ寄せた位置で、第1取付部42を、3つのビス孔44,44・・を用いてフレーム2の縦枠4に仮固定用ビス20,20・・で固定し、第2取付部43も、3つのビス孔44,44・・を用いてフレーム2の横枠5に仮固定用ビス20,20・・で固定して仮固定を行う。   When the vibration control frame 1A configured as described above is also manufactured in advance in a factory or the like, bracket fittings 40, 40 are attached to the diagonal connection portions of the manufactured frame 2, respectively. At this time, as shown in FIG. 8, at the position where the damper fixing portion 41 of each bracket 40 is brought close to one side so as to be the center in the thickness direction of the frame 2, the first mounting portion 42 has three screw holes 44, 44 · · fixed to the vertical frame 4 of the frame 2 with the screws 20, 20 · · · temporarily fixed, the second mounting portion 43 also using the three screw holes 44 · · · · horizontal frame of the frame 2 Perform temporary fixing by fixing to 5 using temporary fixing screws 20, 20.

こうして対角線上に取り付けたブラケット金具40,40の間に、制震ブレース3を掛け渡して、各延長木材8の先端部を、各ブラケット金具40のダンパー固定部41の外側(第1、第2取付部42,43の折曲側と反対側)の面にあてがった状態で、ビス孔17を用いてビス21によって固定する。最後に補強枠6,6を、制震ブレース3の架設側と反対の端面から取り付けると、フレーム2内に制震ブレース3が架設された制震フレーム1Aが得られる。この状態で各ブラケット金具40の第1、第2取付部42,43は延長木材8に隠されることなく露出している。   In this way, the vibration control brace 3 is bridged between the bracket fittings 40 and 40 attached on the diagonal, and the tip end portion of each extension wood 8 is the outer side of the damper fixing portion 41 of each bracket fitting 40 (first and second In a state of being applied to the surface opposite to the bending side of the mounting portions 42 and 43, the mounting portion 42 is fixed by the screw 21 using the screw hole 17.

なお、形態4において、ダンパー固定部のビス孔の数と、本固定用ビス孔及び仮固定用ビス孔の数とは、上記形態に限らず、適宜増減可能である。よって、仮固定用ビス孔を本固定用ビス孔よりも数を少なくすることもできる。本固定部と仮固定部とは左右逆であってもよい。但し、これらのビス孔は全て用いる必要はなく、一部を選択してビスをねじ込むようにしても差し支えない。
また、ダンパー固定部や板体の形状も、例えばダンパー固定部を矩形状以外に延長木材の接合方向へ突出する台形状としたり、正方形状や扇状としたり、板体の両端を同じ長さとしたり、仮固定部の幅を本固定部の幅よりも狭くしたり等、適宜変更可能である。
さらに、仮固定、本固定共にビスによる固定としているが、例えば仮固定を釘打ちとして本固定をビスとする等、仮固定と本固定とで固定手段を変えることもできる。
In the fourth embodiment, the number of screw holes in the damper fixing portion, and the number of permanent fixing screw holes and the temporary fixing screw holes are not limited to the above-described embodiment, and can be increased or decreased appropriately. Therefore, the number of screw holes for temporary fixing can be smaller than the number of screw holes for main fixing. The main fixing portion and the temporary fixing portion may be reversed. However, it is not necessary to use all of these screw holes, and it is also possible to select a part and screw in the screws.
Also, for the shape of the damper fixing portion and the plate, for example, the damper fixing portion has a trapezoidal shape protruding in the joining direction of the extension wood other than the rectangular shape, a square shape or a fan shape, or both ends of the plate have the same length. The width of the temporary fixing portion can be changed as appropriate, such as being narrower than the width of the main fixing portion.
Furthermore, although both temporary fixing and permanent fixing are fixed by screws, for example, the fixing means can be changed between temporary fixing and main fixing, such as temporary fixing being nailing and using this fixing as a screw.

そして、各形態に共通して、制震ブレースは、制震ダンパーの両端に延長木材を接合しているが、延長木材に限らず鋼材等の他の取付部材も採用できる。また、取付部材は制震ダンパーの両端に接合する以外に、例えば制震ダンパーの一端側のみに延長木材等の取付部材を接合して、制震ダンパーの他端を直接ブラケット金具に取り付けることも可能である。   And although it is common to each form, although the vibration control brace joins the extended wood to the both ends of the vibration control damper, not only the extended wood but other attachment members, such as steel materials, are employable. In addition to attaching the mounting member to both ends of the damping damper, for example, a mounting member such as an extension wood may be joined only to one end of the damping damper and the other end of the damping damper may be directly attached to the bracket. It is possible.

さらに、ブラケット金具の形状によっては、ブラケット金具と軸組との間に跨がって補強プレートを設けることも可能である。図13,14はその一例を示すもので、形態1の制震フレーム1を軸組30に取り付ける際に、ブラケット金具13のダンパー固定部14の外側から、上側の仕口部ではダンパー固定部14と柱31及び梁32とに跨がって、下側の仕口部ではダンパー固定部14と柱31及び土台33とに跨がって矩形状の補強プレート70,70をそれぞれ固定している。ここではダンパー固定部14側ではビス21によって補強プレート70も同時に延長木材8へ固定され、柱31や梁32若しくは土台33側ではビス71によって補強プレート70が固定されている。
このような補強プレート70を設ければ、ブラケット金具13と軸組30とがより強固に固定される。なお、補強プレートの形状はこの変更例に限らず、柱側と横架材側とに分けて複数設けたり、ブラケット金具の形状によっては軸組の前後でブラケット金具を挟むように設けたりすることもできる。
Furthermore, depending on the shape of the bracket, it is also possible to provide a reinforcing plate across the bracket and the shaft assembly. FIGS. 13 and 14 show an example thereof. When mounting the vibration control frame 1 of the embodiment 1 to the shaft assembly 30, the damper fixing portion 14 is provided at the upper connection from the outside of the damper fixing portion 14 of the bracket fitting 13. Straddling the column 31 and the beam 32, and fixing the rectangular reinforcing plates 70 and 70 across the damper fixing portion 14 and the column 31 and the base 33 at the lower connection, respectively. . Here, the reinforcing plate 70 is also simultaneously fixed to the extension wood 8 by the screw 21 on the damper fixing portion 14 side, and the reinforcing plate 70 is fixed to the pillar 31, the beam 32 or the base 33 side by the screw 71.
If such a reinforcing plate 70 is provided, the bracket 13 and the shaft assembly 30 are more firmly fixed. In addition, the shape of the reinforcing plate is not limited to this modified example, but a plurality of divisions may be provided separately on the column side and the side of the horizontal mounting member, or depending on the shape of the bracket, the bracket may be provided in front of and behind the shaft assembly. You can also.

また、制震ブレースは対角線上に架設する以外に、一対の制震ダンパーを上下軸対称に配置するいわゆるKブレース状に架設することもできる。この場合も、フレームの仕口部で各制震ダンパーの一端側が取り付けられるブラケット金具と、柱の中間部位で両制震ダンパーの他端側が取り付けられるブラケット金具とに本固定部と仮固定部とを設ければよい。このとき、取付部材は省略して制震ダンパーの端部を直接ブラケット金具に取り付けることもできる。   Further, the vibration control braces may be constructed in a so-called K brace shape in which a pair of vibration control dampers are disposed symmetrically in the vertical axis, in addition to the diagonal arrangement of the vibration control braces. Also in this case, a main fixing portion and a temporary fixing portion are provided with a bracket fitting to which one end side of each damping damper is attached at a joint of the frame, and a bracket fitting to which the other end side of both damping dampers is attached If you At this time, the mounting member may be omitted and the end of the vibration control damper may be directly attached to the bracket.

一方、粘弾性ダンパーは、同軸で重合される複数の管とその間の粘弾性体とからなるスリーブ型に限らず、複数の帯状の鋼板とその間の粘弾性体とからなる積層型であってもよいし、制震ダンパーとしては粘弾性ダンパー以外にオイルダンパー等も採用できる。
また、制震ブレースに限らず、積層型の粘弾性ダンパーを取付部材を介して上下の梁と土台との間に架設する場合も、取付部材と梁及び土台とを接合するブラケット金具に本固定部と仮固定部とを設けて本発明を採用することができる。このような壁型の制震ダンパーでも取付部材を省略して制震ダンパーの端部を直接ブラケット金具に取り付けることは可能である。
On the other hand, the visco-elastic damper is not limited to a sleeve type consisting of a plurality of coaxially polymerized tubes and a visco-elastic body between them, and a multi-layered type consisting of a plurality of strip-like steel plates and visco-elastic body between them In addition to the visco-elastic dampers, oil dampers and the like can also be adopted as vibration control dampers.
In addition, even if a laminated visco-elastic damper is installed between the upper and lower beams and the base via the attachment member as well as the vibration control brace, the bracket is fixed to the bracket metal joining the attachment member to the beam and the base. The present invention can be adopted by providing a part and a temporary fixing part. It is possible to directly attach the end portion of the vibration control damper to the bracket with such a wall type vibration control damper, omitting the mounting member.
