Description

本発明は、建物の壁面を利用して建物の振動を減衰する制震構造に関し、特にロッキング式外壁構造を備えた低層住宅の制震構造に関する。   The present invention relates to a vibration control structure that attenuates vibration of a building by using a wall surface of the building, and more particularly to a vibration control structure of a low-rise house having a locking outer wall structure.

地震等による水平振動を減衰する制震構造を採用した建物が多く提案或いは提供されている。このような制震構造の中で、建物の壁面を利用した制震構造として、特許文献１に示す構成のものがある。これは、梁と柱で囲まれた空間に板ガラス等の板材を配置して、その板材の４辺の夫々略中央部を粘弾性体を介して梁又は柱に支持させた構成となっている。   Many buildings have been proposed or provided that employ a vibration control structure that attenuates horizontal vibration caused by earthquakes. Among such vibration control structures, there is a structure shown in Patent Document 1 as a vibration control structure using a wall surface of a building. This is a structure in which a plate material such as plate glass is arranged in a space surrounded by a beam and a column, and approximately four central portions of the plate material are supported by the beam or the column via a viscoelastic body. .

一方、住宅の外壁取り付け工法として、ロッキング式外壁取付工法がある。これは、外壁を保護するために、軸組フレームごとに軸組フレームと略同一形状に形成した外壁パネルを軸組フレームに緊結せず、回転（ロッキング）可能に取り付けて壁面を形成する工法であり、例えば特許文献２に開示されているような取付金具を用いて、壁面パネルの左右端部を軸組フレームに連結して、地震等の振動により変形する構造体に合わせて回転運動可能に取り付けられる。こうして、軸組フレームの変形に対して、外壁のひび割れや脱落を防止している。   On the other hand, there is a rocking type outer wall mounting method as an outer wall mounting method for a house. In order to protect the outer wall, the outer wall panel formed in approximately the same shape as the shaft frame is attached to the shaft frame so that it can be rotated (locked) to form a wall surface in order to protect the outer wall. Yes, for example, by using mounting brackets as disclosed in Patent Document 2, the left and right ends of the wall panel are connected to the frame frame so that it can rotate according to the structure deformed by vibrations such as earthquakes. It is attached. In this way, the outer wall is prevented from cracking or falling off against deformation of the frame.

図６は、このように取り付けられた壁面を示し、（ａ）は正面説明図、（ｂ）は横断面説明図であり、１５は軸組フレームの柱、１６は梁、１７は外壁パネル、１８は取付金具、１９は外壁パネル１７を支持する支持金具を示している。このように、外壁パネル１７の側部の複数ヶ所を取付金具１８で軸組フレームに取り付けることで、通常は取付金具１８の摩擦力で外壁パネル１７は構造体に押さえ込まれているが、地震等による構造体の変形力が取付金具１８の摩擦力を上回ると外壁パネル１７をフリーにし、この取付金具１８を支点に、構造体が変形する方向に外壁パネル１７を回転させる。   FIG. 6 shows the wall surface attached in this manner, (a) is a front explanatory view, (b) is a transverse cross-sectional explanatory view, 15 is a column of a frame frame, 16 is a beam, 17 is an outer wall panel, Reference numeral 18 denotes a mounting bracket, and 19 denotes a support bracket for supporting the outer wall panel 17. As described above, the outer wall panel 17 is normally pressed into the structure by the frictional force of the mounting bracket 18 by attaching a plurality of portions on the side of the outer wall panel 17 to the frame frame with the mounting bracket 18. When the deformation force of the structure due to the above exceeds the frictional force of the mounting bracket 18, the outer wall panel 17 is made free, and the outer wall panel 17 is rotated in the direction in which the structure is deformed with the mounting bracket 18 as a fulcrum.

しかし、上記特許文献１の技術は、制震構造とするためにはダンパー以外に非構造部材である板材が必要であるため、この構成を上記特許文献２のような取付金具を用いたロッキング式外壁を備えた住宅に適用しようとした場合、複雑な壁面構造となり、大きなコスト増となってしまう。また、粘弾性体取り付け位置が板材の４辺略中央部であるため軸組フレームの初期変形時にダンパーに変形が入り辛かった。
そこで、本発明はこのような問題点に鑑み成されたもので、ロッキング式の外壁構造を有する建物にあっては、外壁パネルのロッキング作用を利用して簡易な構造で、且つ初期変形時を含めて効果的に制震できる制震構造を提供することを目的とする。 However, since the technique of Patent Document 1 requires a plate material that is a non-structural member in addition to the damper in order to obtain a damping structure, this configuration is a locking type using a mounting bracket as in Patent Document 2 above. When trying to apply to a house with an outer wall, it becomes a complicated wall structure, resulting in a large cost increase. Further, since the viscoelastic body mounting position is substantially the center of the four sides of the plate material, it was difficult to deform the damper during the initial deformation of the frame frame.
Therefore, the present invention has been made in view of such problems, and in a building having a rocking-type outer wall structure, it has a simple structure using the locking action of the outer wall panel and can be used at the time of initial deformation. The purpose is to provide a vibration control structure that can effectively control the vibration.

上記課題を解決するため、請求項１の発明は、梁と柱から構成される軸組フレームと、前記軸組フレームにロッキング可能に取り付けられた外壁パネルとを備えた建物の制震構造であって、外壁パネルの少なくとも４隅を含む部位と軸組フレームとの間に粘弾性ダンパーを介在させて、外壁パネルのロッキングに伴って発生する粘弾性ダンパーの剪断変形により建物を制震させることを特徴とする。
この構成により、地震等により軸組フレームに変形が生ずると、外壁パネルはロッキングし、外壁パネルと軸組フレームの間にズレが生ずる。このズレにより粘弾性ダンパーは剪断変形するが、粘弾性ダンパーの復元力により制震される。
このように、外壁パネルのロッキングを利用して制震させるので、制震のための部材が粘弾性ダンパーだけで済む。また、ロッキング時のズレが最も大きい４隅に粘弾性ダンパーが取り付けられるので、軸組フレームの初期変形時にも効果的に粘弾性ダンパーの減衰力が働き、制震させることができる。 In order to solve the above-mentioned problems, the invention of claim 1 is a building vibration control structure comprising a frame frame composed of beams and columns, and an outer wall panel attached to the frame frame so as to be lockable. In addition, a viscoelastic damper is interposed between the part including at least four corners of the outer wall panel and the frame frame, and the building is damped by shear deformation of the viscoelastic damper generated along with the locking of the outer wall panel. Features.
With this configuration, when the shaft frame is deformed by an earthquake or the like, the outer wall panel is locked, and a deviation occurs between the outer wall panel and the shaft frame. This displacement causes shear deformation of the viscoelastic damper, but is controlled by the restoring force of the viscoelastic damper.
As described above, since the damping is performed by using the locking of the outer wall panel, only the viscoelastic damper is required for the damping member. In addition, since the viscoelastic dampers are attached to the four corners where the displacement at the time of locking is the largest, the damping force of the viscoelastic dampers can effectively work and control the vibration even during the initial deformation of the frame frame.

請求項２の発明は、請求項１の発明において、粘弾性ダンパーは、シート状の粘弾性体を鋼板で挟持して形成された板状体であり、前記粘弾性体の剪断面が連結する外壁パネルの壁面に平行であることを特徴とする。
この構成により、粘弾性ダンパーはサンドイッチ構造で簡易な形状で済み、作製が容易である。また、粘弾性体の剪断面が壁面方向即ち外壁パネルのロッキング方向に平行なので、粘弾性ダンパーは外壁パネルのロッキングに直接作用して確実に制震動作するし、壁面背部に貼着するように取り付けできるので粘弾性ダンパーの設置スペースは僅かで済む。 According to a second aspect of the present invention, in the first aspect of the invention, the viscoelastic damper is a plate-like body formed by sandwiching a sheet-like viscoelastic body between steel plates, and the shear planes of the viscoelastic body are connected. It is characterized by being parallel to the wall surface of the outer wall panel.
With this configuration, the viscoelastic damper has a sandwich structure and a simple shape, and is easy to manufacture. In addition, since the shearing surface of the viscoelastic body is parallel to the wall surface direction, that is, the locking direction of the outer wall panel, the viscoelastic damper acts directly on the locking of the outer wall panel to reliably control the vibration and stick to the back of the wall surface. Since it can be installed, the installation space for the viscoelastic damper is small.

請求項３の発明は、請求項１又は２の発明において、軸組フレームの粘弾性ダンパー取付位置は、柱であることを特徴とする。
この構成により、軸組フレームの変形時の外壁パネルとのズレが最も大きい部位に粘弾性ダンパーが設置されるので効果的に粘弾性体を変形させることができる。 The invention of claim 3 is characterized in that, in the invention of claim 1 or 2, the viscoelastic damper mounting position of the shaft frame is a pillar.
With this configuration, the viscoelastic damper can be effectively deformed because the viscoelastic damper is installed at a position where the deviation from the outer wall panel at the time of deformation of the shaft frame is the largest.

請求項４の発明は、請求項２又は３の発明において、粘弾性体が、高減衰エラストマー組成物であることを特徴とする。
この構成により、良好な振動減衰特性を得ることが可能となる。 The invention of claim 4 is characterized in that, in the invention of claim 2 or 3, the viscoelastic body is a highly damped elastomer composition.
With this configuration, it is possible to obtain good vibration damping characteristics.

本発明によれば、外壁パネルのロッキングを利用して制震させるので、制震のための部材が粘弾性ダンパーだけで済む。また、ロッキング時のズレが最も大きい４隅に粘弾性ダンパーが取り付けられるので、軸組フレームの初期変形時にも効果的に粘弾性ダンパーが働き、制震させることができる。   According to the present invention, since the vibration control is performed by using the locking of the outer wall panel, only the viscoelastic damper is required as a member for vibration control. In addition, since the viscoelastic dampers are attached to the four corners where the displacement at the time of locking is the largest, the viscoelastic dampers can effectively work and control the vibration even during the initial deformation of the frame frame.

以下、本発明を具体化した実施の形態を、図面に基づいて詳細に説明する。図１，図２は、本発明に係る制震構造を採用した建物壁面の要部を示し、図１は背面説明図、図２は平面説明図である。図において、１は梁、２は柱、３は粘弾性ダンパーであり、梁１及び柱２で軸組フレームは構成されている。尚、この実施形態も上記図６に示されている様な取付金具１８により、外壁パネルはロッキング可能に軸組フレームに連結されているが、ここでは取付金具を省略してある。また、図１において斜線のハッチング部は外壁パネル４を示し、図１では軸組フレームの背部に設置されている。更に、クロスハッチング部は粘弾性ダンパー３に設けられた粘弾性体部を示している。   DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, embodiments of the invention will be described in detail with reference to the drawings. 1 and 2 show the main part of a building wall surface adopting the vibration control structure according to the present invention, FIG. 1 is a rear view, and FIG. 2 is a plan view. In the figure, 1 is a beam, 2 is a column, 3 is a viscoelastic damper, and the frame 1 and the column 2 constitute a frame. In this embodiment, the outer wall panel is connected to the shaft frame so as to be lockable by the mounting bracket 18 as shown in FIG. 6, but the mounting bracket is omitted here. In FIG. 1, the hatched portion with hatching indicates the outer wall panel 4, and in FIG. Further, the cross hatching portion indicates a viscoelastic body portion provided in the viscoelastic damper 3.

また、図３はＡ部拡大図を示し、図４，図５はその平面説明図及び右側面説明図を示している。この図に示すように、粘弾性ダンパー３は、軸組フレームに取り付けるためのフレーム連結部材５と、長方形シート状の粘弾性体６と、外壁フレーム４に取り付けるための外壁パネル連結部材７とから構成されている。
フレーム連結部材５は、鋼板をＬ字状に折り曲げて形成され、一方の面が柱２に連結するフレーム連結部５ａ、他方の面が粘弾性体を貼着する粘弾性体取付部５ｂとなり、折り曲げた内側中央には、フレーム連結部５ａから粘弾性体連結部５ｂに亘り補強板５ｃが溶接形成されて堅牢な構造となっている。そして、フレーム連結部５ａは、一対のボルト挿通孔が設けられ、ボルト９により柱に連結される。詳しくは、図５に示すように、柱２はＣ形チャンネルで形成されており、その内部に柱２に係合するボルト９の座金としての菱形金具１０が配置され、その菱形金具１０とフレーム連結部５ａとで柱２を挟持してボルト９とナット１１とで固定し、フレーム連結部材５を柱２に連結している。 3 shows an enlarged view of part A, and FIGS. 4 and 5 show a plan view and a right side view thereof. As shown in this figure, the viscoelastic damper 3 includes a frame connecting member 5 for attaching to the frame frame, a rectangular sheet-like viscoelastic body 6, and an outer wall panel connecting member 7 for attaching to the outer wall frame 4. It is configured.
The frame connecting member 5 is formed by bending a steel plate into an L shape, and one surface is a frame connecting portion 5a that connects to the pillar 2, and the other surface is a viscoelastic body attaching portion 5b that adheres a viscoelastic body, A reinforcing plate 5c is welded from the frame connecting portion 5a to the viscoelastic body connecting portion 5b at the bent inner center to form a robust structure. The frame connecting portion 5 a is provided with a pair of bolt insertion holes and is connected to the pillars by the bolts 9. Specifically, as shown in FIG. 5, the pillar 2 is formed by a C-shaped channel, and a rhombus fitting 10 as a washer for the bolt 9 that engages the pillar 2 is disposed therein, and the rhombus fitting 10 and the frame The column 2 is sandwiched between the connecting portions 5 a and fixed with bolts 9 and nuts 11 to connect the frame connecting member 5 to the columns 2.

そして、ここで使用される粘弾性体６の特性としては、減衰定数が３５％以上、また壁面に組み付けた状態では３０％以上が好ましい。具体的な材料としては、スチレン系ブロックポリマーを主成分とする高減衰エラストマー組成物で、例えば特開２００２−１３８１８４号公報で開示されている組成のもの、即ちスチレン系ブロックポリマー全体中のジブロック成分の割合が５０〜９５％のものが好適に使用できる。このような組成の粘弾性体６を用いることで、外壁パネル４のロッキング作用を利用して良好に制震させることが可能となる。また、この実施形態で使用される粘弾性体６の大きさは、例えば１００×２００ｍｍの長方形となっている。   And as a characteristic of the viscoelastic body 6 used here, a damping constant is 35% or more, and 30% or more is preferable in the state assembled | attached to the wall surface. Specific examples of the material include a highly damped elastomer composition mainly composed of a styrene block polymer having a composition disclosed in, for example, Japanese Patent Application Laid-Open No. 2002-138184, that is, diblock in the entire styrene block polymer. Those having a component ratio of 50 to 95% can be preferably used. By using the viscoelastic body 6 having such a composition, it is possible to satisfactorily dampen using the locking action of the outer wall panel 4. Moreover, the magnitude | size of the viscoelastic body 6 used by this embodiment is a rectangle of 100x200 mm, for example.

また、外壁パネル連結部材７は、長方形状の鋼板であり、図３に示すように中央部が粘弾性体６の貼着部であり、その上下にビス止め部７ａが形成されている。このビス止め部７ａには、ビス孔１２が複数穿設されており、このビス孔１２にビス１３を挿入することで、外壁パネル連結部材７は外壁パネル４にビス止めされる。
このように、粘弾性体６は、フレーム連結部材５と外壁パネル連結部材７とで挟持された単純なサンドイッチ構造で板状に形成され、外壁パネル４の裏面に貼着されるように取り付けられる。その結果、粘弾性体６の剪断方向が壁面に平行、即ち外壁パネルのロッキング動作面に平行となるよう配置されている。
尚、Ａ部以外の他の３ヶ所の粘弾性ダンパー３も同様に取り付けられ、外壁パネルの４隅が夫々柱２に連結される。また、粘弾性体６は、上記組成物でなくても使用可能であり、例えばポリウレタン系、或いはスチレン−イソプレン系のものであっても良い。 Moreover, the outer wall panel connection member 7 is a rectangular steel plate, and as shown in FIG. 3, the central portion is a sticking portion of the viscoelastic body 6, and screw fixing portions 7 a are formed on the top and bottom thereof. A plurality of screw holes 12 are formed in the screw fixing portion 7 a, and the outer wall panel connecting member 7 is screwed to the outer wall panel 4 by inserting screws 13 into the screw holes 12.
As described above, the viscoelastic body 6 is formed in a plate shape with a simple sandwich structure sandwiched between the frame connecting member 5 and the outer wall panel connecting member 7 and is attached so as to be attached to the back surface of the outer wall panel 4. . As a result, the viscoelastic body 6 is arranged so that the shear direction is parallel to the wall surface, that is, parallel to the rocking operation surface of the outer wall panel.
In addition, the three viscoelastic dampers 3 other than the portion A are similarly attached, and the four corners of the outer wall panel are respectively connected to the pillars 2. Further, the viscoelastic body 6 can be used even if it is not the above-described composition, and may be, for example, polyurethane-based or styrene-isoprene-based.

こうして形成された粘弾性ダンパー３は、粘弾性体６に剪断方向の力（振動）が加えられると、粘弾性体６が剪断変形する。そして、フレーム連結部材５と外壁パネル連結部材７とが位置ズレを発生するが、そのときフレーム連結部材５と外壁パネル連結部材７の間の相対変位量に比例した大きさの抵抗力が粘弾性体６に発生する。この抵抗力により振動が減衰し、外力が無くなれば粘弾性体６の復元作用で元の位置関係に復帰する。
即ち、地震等により軸組フレームが変形すると、外壁パネルはロッキングし、外壁パネル４に貼着するように取り付けられた粘弾性ダンパー３は、そのロッキングに比例して剪断変形する。その結果、粘弾性体６は変形量に比例した抵抗力を生じ、その復元力により制震される。 In the viscoelastic damper 3 thus formed, when a shearing force (vibration) is applied to the viscoelastic body 6, the viscoelastic body 6 undergoes shear deformation. Then, the frame connecting member 5 and the outer wall panel connecting member 7 are displaced. At that time, the resistance force having a magnitude proportional to the relative displacement between the frame connecting member 5 and the outer wall panel connecting member 7 is viscoelastic. Occurs in the body 6. When this resistance force attenuates the vibration and the external force disappears, the original positional relationship is restored by the restoring action of the viscoelastic body 6.
That is, when the frame is deformed due to an earthquake or the like, the outer wall panel is locked, and the viscoelastic damper 3 attached so as to adhere to the outer wall panel 4 is shear-deformed in proportion to the locking. As a result, the viscoelastic body 6 generates a resistance force proportional to the amount of deformation and is controlled by the restoring force.

このように、外壁パネルを利用して制震させるので、制震のために必要な部材が粘弾性ダンパーだけであり、僅かな部材で構成できる。また、ロッキング時のズレが最も大きい４隅に粘弾性ダンパーが取り付けられるので、軸組フレームの初期変形時にも効果的に粘弾性ダンパーの減衰力が働き、制震させることができる。特に粘弾性ダンパーの軸組フレーム側取付部位を柱とすることで、軸組フレームの変形時の外壁パネルとのズレが最も大きい部位に粘弾性ダンパーが設置されることになり、効果的に粘弾性体を変形させることができる。
また、粘弾性体の剪断方向が壁面方向即ち外壁パネルのロッキング方向に平行なので、粘弾性ダンパーは外壁パネルのロッキングに直接作用して確実に制震動作するし、壁面背部に貼着するように取り付けできるので粘弾性ダンパーの設置スペースは僅かで済む。そして、粘弾性ダンパーはサンドイッチ構造で簡易な形状なので容易に作製できる。 As described above, since the outer wall panel is used to suppress the vibration, only the viscoelastic damper is necessary for the vibration suppression, and a small number of members can be used. In addition, since the viscoelastic dampers are attached to the four corners where the displacement at the time of locking is the largest, the damping force of the viscoelastic dampers can effectively work and control the vibration even during the initial deformation of the frame frame. In particular, by using the attachment part of the viscoelastic damper on the side of the frame frame as a column, the viscoelastic damper is installed at the site where the deviation from the outer wall panel during deformation of the frame frame is the largest, so that The elastic body can be deformed.
In addition, since the shear direction of the viscoelastic body is parallel to the wall surface direction, that is, the locking direction of the outer wall panel, the viscoelastic damper acts directly on the locking of the outer wall panel to reliably control the vibration and stick to the back of the wall surface. Since it can be installed, the installation space for the viscoelastic damper is small. The viscoelastic damper can be easily manufactured because it has a sandwich structure and a simple shape.

尚、上記実施形態では、外壁パネル４と外壁パネル連結部材７とをビスにより連結しているが、接着剤による貼着で連結しても良い。また、外壁パネル４に専用の取付部材を溶接或いは埋め込み等で製造時に取り付けておき、ボルト止めする構造としても良く、そうすれば、粘弾性ダンパーを取り付けた後でも容易に外壁パネルを取り外すことが可能となり、粘弾性ダンパーの交換も可能となる。
また、粘弾性ダンパー３の取り付け位置は、外壁パネル４の４隅の４ヶ所としているが、更に多くの部位、例えば柱２の中央部も粘弾性ダンパー３で連結しても良い。但し、４隅がロッキング時に最も変位量が大きくなるので、この位置に設けるだけでも十分効果的に振動を吸収でき制震作用を奏する。 In addition, in the said embodiment, although the outer wall panel 4 and the outer wall panel connection member 7 are connected with the bis | screw, you may connect by sticking with an adhesive agent. Further, a dedicated attachment member may be attached to the outer wall panel 4 at the time of manufacture by welding or embedding, and may be bolted so that the outer wall panel can be easily removed even after the viscoelastic damper is attached. The viscoelastic damper can be replaced.
In addition, although the attachment positions of the viscoelastic damper 3 are four positions at the four corners of the outer wall panel 4, more parts, for example, the central part of the column 2 may be connected by the viscoelastic damper 3. However, since the amount of displacement becomes the largest when the four corners are rocked, the vibration can be absorbed sufficiently effectively even if it is provided at this position.
