Description

本発明は、制振建物を構成する躯体フレームと壁の間に介装させる振動吸収部材と該振動吸収部材を備えた制振建物に係り、特に、躯体フレームと壁の施工誤差に追従しながら設置することができ、十分に振動吸収性能を発揮することのできる振動吸収部材と該振動吸収部材を備えた制振建物に関する。   The present invention relates to a vibration absorbing member interposed between a frame and a wall constituting a vibration-damping building and a vibration-damping building including the vibration absorbing member, and in particular, following a construction error between the frame and the wall. The present invention relates to a vibration absorbing member that can be installed and can sufficiently exhibit vibration absorbing performance and a vibration-damping building including the vibration absorbing member.

高層建築物においては、地震や風による該建築物の揺れを低減するために、該建築物と同調するように振動する重錘と減衰材とからなる受動的な制振装置や、機械的に該建築物の振動を制御する積極的な制振装置などが該建築物内に設置されている。受動的な制振装置としては例えばＴＭＤ（Ｔｕｎｅｄ Ｍａｓｓ Ｄａｍｐｅｒ）が、積極的な制振装置としては例えばＡＭＤ（Ａｃｔｉｖｅ Ｍａｓｓ Ｄａｍｐｅｒ）がそれぞれ一例として挙げられる。また、鉄骨構造のラーメン架構からなる建築物では、一般に主要なフレーム構造部分をなす柱や梁と可動的にパネル（外壁や内壁）を接合させた構成もある。可動的な接合とは、壁パネルをボルトやリベットなどでフレーム構造に接合させたり、フレーム構造にピン結合乃至ピンローラー結合された補助フレームに壁パネルを接合させたり、壁パネルとフレーム構造の間に弾性部材などを介装させてなる接合構造のことをいう。さらには、梁や柱からなるフレーム架構内に粘弾性のブレス材を設置して、建物振動時の振動エネルギーをブレス材にて吸収する構成もある。耐震性能や風などに対する制振性能を備えた上記する建物、すなわち、制振建物は、高層建築物に限定されるものではなく、近時では、階層が２又は３階の木造や鉄骨造のユニット式戸建て住宅もその対象となっている。   In a high-rise building, in order to reduce the shaking of the building due to an earthquake or wind, a passive damping device composed of a weight and a damping material that vibrates in synchronization with the building, or mechanically An active vibration control device for controlling vibration of the building is installed in the building. Examples of passive vibration control devices include TMD (Tuned Mass Damper), and examples of active vibration control devices include AMD (Active Mass Damper). In addition, in a building composed of a steel frame rigid frame, there is generally a structure in which a panel (outer wall or inner wall) is movably joined to a column or beam forming a main frame structure. Movable joining refers to joining the wall panel to the frame structure with bolts or rivets, joining the wall panel to an auxiliary frame that is pin-coupled or pin-roller joined to the frame structure, or between the wall panel and the frame structure. It means a joining structure in which an elastic member or the like is interposed. Furthermore, there is also a configuration in which a viscoelastic brace material is installed in a frame structure made up of beams and columns, and vibration energy at the time of building vibration is absorbed by the brace material. Buildings with the above-mentioned anti-seismic performance and vibration control performance against wind etc., that is, the vibration control building is not limited to high-rise buildings, and recently, the floor is made of 2 or 3 floor wooden or steel structure This is also the case for unit-type detached houses.

制振建物の建設に際し、上記するような受動的な制振装置や積極的な制振装置を設置することは、超高層ビルなどの大規模建築物には容易に適用することはできても、中〜低層建築物、特にユニット式の戸建て住宅などには設置スペースやコストの面から適用し難いのが現状である。   When constructing a vibration control building, installing passive vibration control devices or active vibration control devices as described above can be easily applied to large-scale buildings such as skyscrapers. In the present situation, it is difficult to apply to medium to low-rise buildings, especially unit-type detached houses from the viewpoint of installation space and cost.

上記の問題に対して、特許文献１では、建物自体の構成部材で該建物の振動を減衰させる制振建物において、建物の躯体フレームと相対的に変位する外壁パネルとの間に振動吸収部材を介装させる発明が開示されている。この振動吸収部材としては、硬化後に弾性性状を示す接着剤や同性状を示す粘着テープを使用し、これらを躯体フレームや外壁パネルに両面固定することにより振動吸収部材の取り付けが行われることとなる。   With respect to the above problem, in Patent Document 1, in a vibration-damping building that attenuates the vibration of the building by a component of the building itself, a vibration absorbing member is provided between the building frame and the outer wall panel that is relatively displaced. An intervening invention is disclosed. As the vibration absorbing member, an adhesive that exhibits elasticity after curing or an adhesive tape that exhibits the same property is used, and the vibration absorbing member is attached by fixing them to a frame or an outer wall panel on both sides. .

また、特許文献２では、振動吸収部材として発砲プラスチックやゴム状弾性体からなる制振テープを使用し、該制振テープの一側面は躯体フレームや壁パネルと接着させ、他側面は躯体フレームや壁パネルと接着または高摩擦抵抗状態で圧接させる方法が開示されている。
特開２００１−３４５５号公報 特開２００１−３２３６８５号公報 In Patent Document 2, a vibration damping tape made of foamed plastic or rubber-like elastic material is used as a vibration absorbing member, one side of the vibration damping tape is bonded to a frame or wall panel, and the other side is a frame or There is disclosed a method of pressure-contacting a wall panel in an adhesive or high friction resistance state.
JP 2001-3455 A Japanese Patent Laid-Open No. 2001-323865

特許文献１、２に開示の振動吸収部材によれば、ユニット式の戸建て住宅などにおいても、比較的低コストで容易に制振性能を具備させることができる。しかし、振動吸収部材がテープ状の部材である場合は、建物の施工誤差を十分に吸収することができない。すなわち、施工誤差によって振動吸収部材の設置部分の空隙が大きくなると該振動吸収部材が
十分に圧着できず、よってその性能を十分発揮することができなくなるし、振動吸収部材の設置部分の空隙が狭くなると、該振動吸収部材が躯体フレームや壁パネルを押し広げることとなって躯体フレームや壁パネルに反りや変形を生じさせる場合がある。 According to the vibration-absorbing members disclosed in Patent Documents 1 and 2, even in a unit-type detached house or the like, vibration damping performance can be easily provided at a relatively low cost. However, when the vibration absorbing member is a tape-like member, it is not possible to sufficiently absorb building construction errors. That is, if the gap in the installation portion of the vibration absorbing member becomes large due to construction errors, the vibration absorbing member cannot be sufficiently crimped, and thus the performance cannot be sufficiently exhibited, and the gap in the installation portion of the vibration absorbing member is narrow. As a result, the vibration absorbing member pushes and expands the frame and the wall panel, which may cause the frame and the wall panel to be warped and deformed.

また、振動吸収部材が硬化後に弾性性状を示す接着剤の場合には、硬化によって振動吸収部材の硬度が高くなることがある。振動吸収部材の硬度が高い場合、躯体フレームや壁パネルの変形が大きくなると、振動吸収部材の該変形に対する抵抗力が大きいために（振動吸収部材が壁パネルや躯体フレームを拘束する拘束力が大きいために）、躯体フレームや壁パネルのうち振動吸収部材との接着部分が損傷してしまうといった問題が生じ得る。   In the case where the vibration absorbing member is an adhesive that exhibits elasticity after curing, the hardness of the vibration absorbing member may be increased by curing. When the hardness of the vibration absorbing member is high, if the deformation of the frame or wall panel increases, the resistance of the vibration absorbing member to the deformation is large (the binding force that the vibration absorbing member constrains the wall panel or frame is large) For this reason, there may be a problem that the bonded portion of the frame or wall panel with the vibration absorbing member is damaged.

本発明の振動吸収部材は、上記する問題に鑑みてなされたものであり、比較的低コストで容易に躯体フレームと壁（壁パネル）との間に介装することができ、建物の施工誤差にも十分に追従でき、設置後にはその振動吸収性能を十分に発揮できる振動吸収部材を提供することを目的としている。また、かかる振動吸収部材を備えることによって、低コストで容易に制振構造を具備し得る制振建物を提供することを目的としている。   The vibration absorbing member of the present invention has been made in view of the above-described problems, and can be easily interposed between a frame and a wall (wall panel) at a relatively low cost. It is an object of the present invention to provide a vibration absorbing member that can sufficiently follow the vibration and can sufficiently exhibit its vibration absorbing performance after installation. Another object of the present invention is to provide a vibration-damping building that can easily include a vibration-damping structure at low cost by including such a vibration absorbing member.

前記目的を達成すべく、請求項１に記載の発明による振動吸収部材は、制振建物を構成する躯体フレームと壁の間に介装させる振動吸収部材であって、その表面に凹凸部が形成されていることを特徴とする。ここで、制振建物とは、耐震性能や風などに対する制振性能を備えた建物のことを意味しており、建物の構成は、低層のユニット式戸建て住宅をはじめ、中層〜高層の建物全般を示す広い概念である。また、躯体フレームとは、鉄骨造や木造を問わず、建物の主要な構造である梁や柱からなるフレームを意味している。さらに、壁とは例えば壁パネルを意味し、躯体フレームの内側に取り付く内壁と、外側に取り付く外壁を含んだ概念である。   In order to achieve the above object, the vibration absorbing member according to the first aspect of the present invention is a vibration absorbing member interposed between a frame and a wall constituting a vibration-damping building, and an uneven portion is formed on the surface thereof. It is characterized by being. Here, a vibration-damped building means a building that has seismic performance and vibration-damping performance against wind, etc., and the structure of the building is a low-rise unit-type detached house, as well as medium to high-rise buildings in general. Is a broad concept. In addition, the frame of the frame means a frame made of beams and pillars, which is the main structure of a building, regardless of whether it is steel or wooden. Furthermore, a wall means a wall panel, for example, and is a concept including an inner wall attached to the inside of the frame and an outer wall attached to the outside.

振動吸収部材は、例えば薄層のシートからなり、その一側面または両側面に凹凸部を備えた部材である。振動吸収部材の層厚は、躯体フレームと壁（壁パネル）との間の所望の隙間に介装でき、かつ躯体フレームおよび壁と確実に接着できる適宜の厚さであればよい。凹凸部の形状は多様な実施形態が考えられるが、例えば、凸部が振動吸収部材の側面において点状に散在することによって凹凸部を形成する場合や、断面視が凸状で一条形態の凸部が複数条設けられていることによって凹凸部を形成する場合などがある。凸部が振動吸収部材の側面において点状に散在するように成形するためには、例えばシートの側面に複数の凸部を突出させた形状に成形したり、シートの側面に複数の凹部を刻設することによって凹凸部が成形される。   The vibration absorbing member is a member made of, for example, a thin sheet, and provided with an uneven portion on one side surface or both side surfaces thereof. The layer thickness of the vibration absorbing member may be an appropriate thickness that can be interposed in a desired gap between the frame and the wall (wall panel) and can be securely bonded to the frame and the wall. Various embodiments can be considered for the shape of the concavo-convex part.For example, when the concavo-convex part is formed by scattering the convex part in a dotted shape on the side surface of the vibration absorbing member, or when the concavo-convex part is convex in a cross-sectional view, An uneven part may be formed by providing a plurality of parts. In order to form the convex portions so as to be scattered in the form of dots on the side surfaces of the vibration absorbing member, for example, the convex portions are formed in a shape in which a plurality of convex portions protrude from the side surface of the sheet, or a plurality of concave portions are etched on the side surface of the sheet. As a result, the concavo-convex part is formed.

かかる凹凸部を振動吸収部材の一側面または両側面に設けることにより、躯体フレームおよび壁の構築に際して生じ得る施工誤差に追従しながら、躯体フレームと壁の間に該振動吸収部材を介装することができる。すなわち、予め、躯体フレームと壁との間の設計上の隙間よりも厚めに成形した振動吸収部材を用意しておき、施工誤差により実際の隙間が設計上の隙間よりも大きな場合にはそのまま振動吸収部材を設置することができる。一方、隙間が設計上の隙間よりも狭い場合には凸部が凹部側に潰れることで振動吸収部材の厚みは自在に変化できるため、振動吸収部材をかかる隙間に容易に設置することができる。このように、振動吸収部材の凸部は凹部側に潰れることによって振動吸収部材の厚みを変化させることができるため、該振動吸収部材が躯体フレームや壁を過度に押圧するといった問題は生じない。   By providing such uneven portions on one or both sides of the vibration absorbing member, the vibration absorbing member is interposed between the frame and the wall while following construction errors that may occur when building the frame and wall. Can do. That is, prepare a vibration absorbing member molded in advance thicker than the design gap between the frame and the wall, and if the actual gap is larger than the design gap due to construction errors, it will vibrate as it is. An absorbent member can be installed. On the other hand, when the gap is narrower than the designed gap, the thickness of the vibration absorbing member can be freely changed by crushing the convex portion toward the concave portion, so that the vibration absorbing member can be easily installed in the gap. Thus, since the convex part of the vibration absorbing member can be crushed to the concave part side, the thickness of the vibration absorbing member can be changed, so that the problem that the vibration absorbing member excessively presses the frame or the wall does not occur.

また、請求項２に記載の発明による振動吸収部材は、部材内部に空洞部が形成されていることを特徴とする。ここで、空洞部とは、球体状の空洞や、一条形態の空洞など適宜の形状を選定できる。かかる空洞部が振動吸収部材の内部に形成されていることによって、
上記の凹凸部と同様に、施工誤差に追従した振動吸収部材の設置が可能となる。上記の凹凸部の場合は、凸部が凹部側に潰れることによって設置される隙間に柔軟に対応することができるが、この空洞部を設けた場合は、該空洞部の体積が減少するように潰されることによって振動吸収部材がその厚さ方向に潰れることができ、隙間に柔軟に対応することができる。 The vibration absorbing member according to the second aspect of the invention is characterized in that a cavity is formed inside the member. Here, as the hollow portion, an appropriate shape such as a spherical hollow or a single-row hollow can be selected. By forming such a cavity inside the vibration absorbing member,
Similarly to the above-described uneven portion, it is possible to install a vibration absorbing member that follows construction errors. In the case of the above concavo-convex part, the convex part can be flexibly accommodated to the gap that is set by collapsing to the concave part side, but when this hollow part is provided, the volume of the hollow part is reduced. By being crushed, the vibration absorbing member can be crushed in the thickness direction, and the gap can be flexibly handled.

なお、上記する凹凸部と空洞部を組み合わせた構成としてもよい。例えば、一条形態の凸部を備えた振動吸収部材において、該凸部内に、凸部の延伸方向に沿うように一条形態の空洞部を備えた構成とすることなどが考えられる。   In addition, it is good also as a structure which combined the above-mentioned uneven | corrugated | grooved part and a cavity part. For example, in a vibration absorbing member having a single-line-shaped convex part, a configuration in which a single-line-shaped hollow part is provided in the convex part along the extending direction of the convex part may be considered.

また、請求項３に記載の発明による前記振動吸収部材は、弾性体からなる特徴とする。ここでいう弾性体とは、例えばゴム製材料のように弾性性能を備えた材質からなるものをいう。振動吸収部材が弾性性能を備えていることと、上記するような凹凸部や空洞部を備えた形状であることが相俟って、施工誤差に追従した振動吸収部材の設置が可能となり、また躯体フレームと壁にそれぞれ確実に振動吸収部材を接着することができるため、躯体フレームおよび壁の相対変位エネルギーを効果的に該振動吸収部材にて吸収することができる。   According to a third aspect of the present invention, the vibration absorbing member is made of an elastic body. An elastic body here means what consists of a material provided with elastic performance like a rubber material, for example. In combination with the vibration absorbing member having elastic performance and the shape having the uneven part and the hollow part as described above, it is possible to install the vibration absorbing member following the construction error. Since the vibration absorbing member can be securely bonded to the housing frame and the wall, the relative displacement energy of the housing frame and the wall can be effectively absorbed by the vibration absorbing member.

また、請求項４に記載の発明による前記振動吸収部材は、発砲樹脂体からなることを特徴とする。ここで、発砲樹脂体とは、発砲ポリスチロールや発砲ポリウレタンなどの発砲プラスチックなどをいう。発砲樹脂体は、軽量で多孔質であるために施工性がよく、クッション性（弾性）や断熱性に優れた材料である。かかる発砲樹脂体からなる振動吸収部材を使用することにより、上記の弾性体と同様の効果が期待できる。   According to a fourth aspect of the present invention, the vibration absorbing member is made of a foamed resin body. Here, the foamed resin body refers to a foamed plastic such as a foamed polystyrene or a foamed polyurethane. Since the foamed resin body is lightweight and porous, it has good workability and is excellent in cushioning properties (elasticity) and heat insulation. By using a vibration absorbing member made of such a foamed resin body, the same effect as that of the elastic body can be expected.

また、請求項５に記載の発明による前記振動吸収部材は、その一側面が少なくとも粘着性能を備え、その他側面が少なくとも摩擦性能を備えていることを特徴とする。例えば、振動吸収部材のうち、粘着性能を備えた一側面を躯体フレームを構成する梁や柱に接着する。一方、摩擦性能を備えた他側面としては、例えば高摩擦抵抗材シール面として壁（壁パネル）に接着したり、高摩擦抵抗材からなる面として壁に圧接する。   The vibration absorbing member according to the invention described in claim 5 is characterized in that one side surface thereof has at least adhesive performance and the other side surface thereof has at least friction performance. For example, of the vibration absorbing member, one side surface having adhesive performance is bonded to a beam or a column constituting the frame. On the other hand, as another side surface provided with friction performance, it adheres to a wall (wall panel), for example as a high friction resistance material sealing surface, or press-contacts to a wall as a surface which consists of high friction resistance materials.

かかる構成とすることにより、建物が振動することによって躯体フレームと壁との相対変位が大きくなり、該相対変位によって生じる力が振動吸収部材の摩擦性能を備えた面の摩擦力を超えると、振動吸収部材は一定の摩擦抵抗を発揮しながら所望の減衰性能をも発揮して、建物の変形に追従することができる。すなわち、想定される相対変位量に対応する適宜の最大摩擦力で該摩擦抵抗力はピークカットされるため、該振動吸収部材が過度に壁（または躯体フレーム）を拘束することがなく、したがって壁や躯体フレームを損壊させることもない。   With this configuration, the relative displacement between the frame and the wall increases due to the vibration of the building, and if the force generated by the relative displacement exceeds the frictional force of the surface having the frictional performance of the vibration absorbing member, The absorbing member exhibits a desired friction performance while exhibiting a certain frictional resistance, and can follow the deformation of the building. That is, since the frictional resistance force is peak-cut at an appropriate maximum frictional force corresponding to the assumed relative displacement amount, the vibration absorbing member does not excessively restrain the wall (or the housing frame), and thus the wall There is no damage to the frame.

さらに、請求項６に記載の発明による制振建物は、躯体フレームに壁が可動的に取り付けられ、躯体フレームと壁の間に前記振動吸収部材を介装させたことを特徴とする。振動吸収部材は、上記するような凹凸部を備えた形状、その内部に空洞部を備えた形状、凹凸部および空洞部を備えた形状に成形でき、さらにはゴム製または発砲樹脂製の材質でかつ上記形状に成形されることもできる。また、上記形状や上記材質を備えるとともに、その一側面は粘着性能を、その他側面は摩擦性能を少なくとも有した振動吸収部材を使用することができる。かかる実施形態の振動吸収部材を躯体フレームを構成する柱や梁と、外壁や内壁となる壁パネルとの間に適宜介装させることにより、簡易な施工でかつ比較的低コストで制振建物を構築することが可能となる。   Furthermore, the vibration-damping building according to the invention described in claim 6 is characterized in that a wall is movably attached to the frame and the vibration absorbing member is interposed between the frame and the wall. The vibration-absorbing member can be formed into a shape having an uneven portion as described above, a shape having a hollow portion therein, a shape having an uneven portion and a hollow portion, and a material made of rubber or foaming resin. And it can also be formed into the above shape. Moreover, while providing the said shape and said material, the vibration absorption member which has the adhesive performance on the one side and at least the friction performance on the other side can be used. By suitably interposing the vibration absorbing member of such an embodiment between the pillars and beams constituting the frame and the wall panel as the outer wall and the inner wall, the vibration control building can be constructed with simple construction and at a relatively low cost. It becomes possible to construct.

ここで、「躯体フレームに壁が可動的に取り付けられ」とは、例えば、柱と梁からなる建物の主要な躯体フレーム内にボルト止め等された間柱（補助フレーム）に、内壁や外壁
をボルトやリベットなどで取り付けることをいう。この補助フレームは、ボルト止めのほか、取り付けられる梁の側面に設けた溝部に、間柱の取り付け端部に設けた突起が嵌装された構成とすることもできるなど多様である。このように、補助フレームは躯体フレームと完全拘束しない状態で取り付けられているため、補助フレームは躯体フレームの変形に容易に追従しながら変形することができる。さらに、躯体フレームと補助フレームの取り付け部は、ピン結合乃至ピンローラー結合を有していることから、かかる取り付け部には過度の断面力（曲げモーメント）が生じることがなく、したがって取り付け部の損壊の可能性は極めて低くなる。 Here, “the wall is movably attached to the frame” means, for example, that the inner wall and the outer wall are bolted to a stud (auxiliary frame) that is bolted in the main frame of the building consisting of columns and beams. Attaching with rivets. In addition to bolting, the auxiliary frame can be variously configured such that a groove provided on a side surface of a beam to be attached can be provided with a protrusion provided on an attachment end of a stud. As described above, since the auxiliary frame is attached without being completely restrained with the frame, the auxiliary frame can be deformed while easily following the deformation of the frame. Furthermore, since the attachment part of the frame and the auxiliary frame has a pin connection or a pin roller connection, an excessive cross-sectional force (bending moment) does not occur in the attachment part, and therefore the attachment part is damaged. The possibility of is very low.

例えば外壁を躯体フレームに取り付ける場合は、外壁の上端部および下端部は躯体フレームを構成する上梁および下梁に振動吸収部材を介してそれぞれ取り付け、外壁の左右端部は補助フレームである間柱にボルトやリベットなどで取り付けることができる。建物が振動して躯体フレームが変形した際には、補助フレームは躯体フレームに対して可動的に追従変形し、外壁は、その左右端において該補助フレームに同調するように変形するとともに、その上下端では振動吸収部材を介して躯体フレームに対して相対変形することとなる。このように、躯体フレームに対して可動的に取り付けられた補助フレームに壁を取り付けることによって、実質的には壁が躯体フレームに可動的に取り付けられていることとなる。   For example, when the outer wall is attached to the frame, the upper and lower ends of the outer wall are attached to the upper and lower beams constituting the frame by means of vibration absorbing members, and the left and right ends of the outer wall are attached to the studs that are auxiliary frames. Can be attached with bolts or rivets. When the building is deformed due to vibration of the building, the auxiliary frame is movably following the frame, and the outer wall is deformed so as to synchronize with the auxiliary frame at its left and right ends, and the upper and lower At the end, it is deformed relative to the housing frame via the vibration absorbing member. Thus, by attaching the wall to the auxiliary frame movably attached to the housing frame, the wall is substantially movably attached to the housing frame.

以上の説明から理解できるように、本発明の振動吸収部材によれば、施工誤差に柔軟に対応しながら躯体フレームと壁の間に該振動吸収部材を設置することができる。また、本発明の振動吸収部材は、躯体フレームおよび壁と確実に接合されるため、躯体フレームと壁の相対変位エネルギーを確実に吸収しながら建物全体の振動を緩和することができる。さらに、上記する振動吸収部材を備えた本発明の制振建物は、簡易かつ比較的低コストな施工で優れた制振性能を発揮することができる。   As can be understood from the above description, according to the vibration absorbing member of the present invention, it is possible to install the vibration absorbing member between the frame and the wall while flexibly responding to construction errors. In addition, since the vibration absorbing member of the present invention is reliably joined to the frame and the wall, the vibration of the entire building can be mitigated while reliably absorbing the relative displacement energy between the frame and the wall. Furthermore, the vibration-damping building of the present invention provided with the vibration absorbing member described above can exhibit excellent vibration-damping performance with simple and relatively low-cost construction.

以下、図面を参照して本発明の実施の形態を説明する。図１は、躯体フレームおよび補助フレームと壁パネルを取り付ける前の斜視図である。図２〜図５は、本発明の振動吸収部材の実施形態を示した斜視図である。なお、以下の説明では、制振建物２としてユニット式の戸建て住宅を想定し、躯体フレーム３に外壁用の壁パネル４を取り付ける場合について説明するが、制振建物はユニット式戸建て住宅に拘束されるものではなく、また内壁用の壁パネルを取り付ける場合にも本発明が適用されることは勿論である。   Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a housing frame, an auxiliary frame, and a wall panel before being attached. 2 to 5 are perspective views showing embodiments of the vibration absorbing member of the present invention. In the following description, a unit type detached house is assumed as the damping building 2 and a case in which a wall panel 4 for an outer wall is attached to the frame 3 is described. However, the damping building is restrained by the unit type detached house. Of course, the present invention is also applied to the case where a wall panel for an inner wall is attached.

図１は、柱３１、３１と梁３２，３２とからなる躯体フレーム３に壁パネル４を取り付ける前の状況を示している。なお、躯体フレーム３は、制振建物２の妻行き方向と桁行き方向にそれぞれ複数連接されるものである。壁パネル４は、制振建物２の重量に対して制振構造を構成するアブソーバー錘をなす適当な重量を有しているのが好ましい。躯体フレーム３を構成する上梁３２と下梁３２の間には、間柱などの補助フレーム５を介在させた構成としておく。この補助フレーム５の端部と梁３２との取り付け方法は、図示しないが、ボルト止めや、梁３２の側面に設けた溝部に、補助フレーム５の端部に設けた突起を嵌装させるなどして取り付けられる。また、プレート金具などを介してボルト止めすることもできる。補助フレーム５の壁パネル４が取り付く面には止め金具６（ボルトやリベットなど）嵌装用の穴５１が刻設してあり、壁パネル４の取り付け時には壁パネル４に設けた穴４１と補助フレーム５の穴５１を止め金具６が嵌装できるようになっている。かかる穴４１，５１は、予め刻設されずに止め金具６を打ち込む際にできる場合もある。   FIG. 1 shows a situation before the wall panel 4 is attached to the frame 3 composed of the columns 31 and 31 and the beams 32 and 32. Note that a plurality of the frame frames 3 are connected to each other in the direction of the wife and the direction of the girder of the damping building 2. It is preferable that the wall panel 4 has an appropriate weight that forms an absorber weight constituting the damping structure with respect to the weight of the damping building 2. An auxiliary frame 5 such as a stud is interposed between the upper beam 32 and the lower beam 32 constituting the frame 3. Although the method of attaching the end of the auxiliary frame 5 to the beam 32 is not shown in the figure, it can be bolted or a projection provided on the end of the auxiliary frame 5 can be fitted into a groove provided on the side of the beam 32. Attached. It can also be bolted via a plate fitting or the like. A hole 51 for fitting a stopper 6 (bolt, rivet, etc.) is provided on the surface of the auxiliary frame 5 to which the wall panel 4 is attached. When the wall panel 4 is attached, the hole 41 provided in the wall panel 4 and the auxiliary frame The stopper 5 can be fitted into the five holes 51. The holes 41 and 51 may be formed when the stopper 6 is driven without being previously engraved.

補助フレーム５の端部と梁３２との取り付け部の構造は、制振建物２の振動時に躯体フレーム３が変形を生じた際、かかる取り付け部にて過度の断面力が生じることなく、補助
フレーム５自体がスムーズに躯体フレーム３に追従した変形ができるようなピン結合構造乃至ピンローラー結合構造であればよく、かかる結合構造を満足する補助フレーム５と梁３２との取り付け方法であれば適宜の方法でよい。 The structure of the attachment portion between the end portion of the auxiliary frame 5 and the beam 32 is such that when the frame 3 is deformed during vibration of the vibration control building 2, the auxiliary frame does not generate excessive cross-sectional force at the attachment portion. 5 itself may be a pin coupling structure or a pin roller coupling structure that can be smoothly deformed following the frame 3, and any method can be used as long as the auxiliary frame 5 and the beam 32 are attached to satisfy the coupling structure. The method is fine.

一方、上梁３２と下梁３２の壁パネル４が取り付く面にはシート状の振動吸収部材１が接着されている。振動吸収部材１は、例えば、ゴム製材料からなる弾性体、または弾性性能を備えた発砲プラスチック材料などの発砲樹脂体から製作される。振動吸収部材１の実施形態を図２〜図５に示す。   On the other hand, the sheet-like vibration absorbing member 1 is bonded to the surface of the upper beam 32 and the lower beam 32 to which the wall panel 4 is attached. The vibration absorbing member 1 is manufactured, for example, from a foamed resin body such as an elastic body made of a rubber material or a foamed plastic material having an elastic performance. Embodiments of the vibration absorbing member 1 are shown in FIGS.

図２ａは、シート部１０の一側面に複数の凸部１１、１１、…を設けた形状の振動吸収部材１Ａを示している。かかる凸部１１，１１…を設けることによって、凸部１１と凸部１１の間には相対的に凹部が形成されることとなる。このシート部１０の厚さや凸部１１の高さ、シート部１０の下面から凸部１１の先端までの全体高さ（すなわち振動吸収部材１Ａの厚み）は、壁パネル４と躯体フレーム３の間の設計上の隙間に対応できる適宜の高さでよい。もっとも、設計上の隙間幅よりも施工誤差によって隙間幅が広がる場合を考慮して、予め全体高さを高めに（すなわち振動吸収部材１Ａの厚みを厚めに）製作しておくのが好ましい。施工誤差によって隙間幅が設計上の隙間幅よりも小さくなった場合でも、弾性性状を有する振動吸収部材１Ａは、凸部１１が凹部側に潰れることによって全体の厚みが小さくなり、容易に隙間内に設置される。なお、凸部１１，１１，…は、シート部１０の一側面のみでなく、両側面に設けることもできる。   FIG. 2A shows a vibration absorbing member 1A having a shape in which a plurality of convex portions 11, 11,. By providing the convex portions 11, 11..., A concave portion is relatively formed between the convex portion 11 and the convex portion 11. The thickness of the sheet part 10, the height of the convex part 11, and the total height from the lower surface of the sheet part 10 to the tip of the convex part 11 (that is, the thickness of the vibration absorbing member 1 </ b> A) are between the wall panel 4 and the housing frame 3. The height may be an appropriate height corresponding to the design gap. However, in consideration of the case where the gap width widens due to the construction error rather than the designed gap width, it is preferable that the overall height is increased in advance (that is, the thickness of the vibration absorbing member 1A is increased). Even when the gap width becomes smaller than the designed gap width due to the construction error, the vibration absorbing member 1A having elastic properties is reduced in the overall thickness due to the convex portion 11 being crushed toward the concave portion. Installed. The convex portions 11, 11,... Can be provided not only on one side surface of the sheet portion 10, but also on both side surfaces.

図２ｂは、シート部１０の一側面に凹部１２，１２…を刻設した振動吸収部材１Ｂを示している。このように、凹部１２，１２…を設けることによって、凹部１２と凹部１２の間には相対的に凸部が形成される。施工誤差によって振動吸収部材１Ｂを設置する隙間が狭い場合には、上記する実施形態と同様に、凸部が凹部１２側に潰れることによって全体の厚みを小さくすることができる。   FIG. 2 b shows a vibration absorbing member 1 </ b> B in which recesses 12, 12. Thus, by providing the recesses 12, 12..., A relatively convex portion is formed between the recess 12 and the recess 12. When the gap for installing the vibration absorbing member 1B is narrow due to construction errors, the entire thickness can be reduced by collapsing the convex portion toward the concave portion 12 as in the above-described embodiment.

図２ｃは、シート部１０の一側面に断面視が凸状で一条形態の凸部１３を複数条設けた振動吸収部材１Ｃが示されている。かかる実施形態も、一条形態の凸部１３、１３で挟まれた部分には相対的に凹部が形成され、凸部１３は凹部側へ容易に潰れることができる。   FIG. 2 c shows a vibration absorbing member 1 </ b> C in which one side surface of the sheet portion 10 has a convex shape in cross-sectional view and a plurality of one-shaped convex portions 13 are provided. In this embodiment as well, a concave portion is formed relatively in the portion sandwiched between the convex portions 13 and 13 in the form of a single line, and the convex portion 13 can be easily crushed toward the concave portion side.

図３には、シート部１０の内部に複数条の空洞部１４，１４、…が形成されてなる振動吸収部材１Ｄが示されている。なお、空洞部１４は、図示する一条形態のほか、楕円体や球状体であってもよい。振動吸収部材１Ｄを設置する隙間が狭い場合には、空洞部１４が潰されることによって振動吸収部材１Ｄ全体の厚みが小さくなることで施工誤差に追従することができる。   FIG. 3 shows a vibration absorbing member 1D in which a plurality of cavities 14, 14,... In addition, the hollow part 14 may be an ellipsoid or a spherical body in addition to the illustrated single-row form. When the gap for installing the vibration absorbing member 1D is narrow, the thickness of the entire vibration absorbing member 1D can be reduced by crushing the cavity portion 14 to follow the construction error.

図４には、振動吸収部材１Ｃと振動吸収部材１Ｄを組み合わせたような実施形態（振動吸収部材１Ｅ）が示されている。ずなわち、シート部１０の一側面には一条形態の凸部１３を複数条設け、かかる凸部１３とシート部１０の内部には球状体や一条形態の空洞部１４を設けたものである。かかる実施形態によれば、凸部１３は施工誤差に応じて空洞部１４がない場合よりも潰れ易くなるため、凸部１３の高さをより高く製作しておく（すなわち、振動吸収部材１Ｅの厚みをより厚く製作しておく）ことができ、例えば振動吸収部材１Ｃよりも広範囲の施工誤差に追従することが可能となる。   FIG. 4 shows an embodiment (vibration absorbing member 1E) in which the vibration absorbing member 1C and the vibration absorbing member 1D are combined. That is, a plurality of strip-shaped convex portions 13 are provided on one side of the sheet portion 10, and a spherical body or a single-strand-shaped hollow portion 14 is provided inside the convex portion 13 and the sheet portion 10. . According to this embodiment, since the convex portion 13 is more easily crushed than the case where there is no hollow portion 14 depending on the construction error, the height of the convex portion 13 is made higher (that is, the vibration absorbing member 1E). For example, it is possible to follow a wider range of construction errors than the vibration absorbing member 1C.

以上説明した振動吸収部材１は、上記するように、例えばシート部１０のフラットな一側面を上梁３２または下梁３２と接着し、凸部１１，１３や凹部１２を備えた他側面で壁パネル４と圧接または接着されることによって躯体フレーム３と壁パネル４の間に介装される。   As described above, the vibration absorbing member 1 described above has, for example, a flat one side surface of the seat portion 10 bonded to the upper beam 32 or the lower beam 32 and a wall on the other side surface including the convex portions 11 and 13 and the concave portion 12. The panel 4 is interposed between the frame 3 and the wall panel 4 by being pressed or bonded to the panel 4.

図５には、図３に示す振動吸収部材１Ｄの一側面に粘着性能を有する例えば粘着シール層１５を備え、他側面には高摩擦抵抗材層１６を備えてなる振動吸収部材１Ｆを示している。例えば、粘着シール層１５と上梁３２または下梁３２とを接着させ、高摩擦抵抗材層１６を壁パネル４と圧接させる。高摩擦抵抗材層１６は、所定のピーク値まで摩擦抵抗性能を発揮でき、ピーク値を超える外力が作用した際にはピークカットされてそれ以上の摩擦抵抗を発揮しない性能をもっている。かかる性能によって、躯体フレーム３と壁パネル４との間に生じる相対変位に対してはある一定の範囲までは摩擦抵抗によって追従でき、一定の範囲を超えると振動吸収部材１Ｅは壁パネル４をピークの摩擦抵抗でしか拘束しなくなる。したがって、壁パネル４は、躯体フレーム３に可動的に取り付けられた補助フレーム５とともに躯体フレーム３の変形に追従しながら変形することとなる。摩擦抵抗をある一定値でピークカットさせることにより、振動吸収部材１Ｅによって壁パネル４を過度に躯体フレーム３に拘束しないこととなり、一定の摩擦抵抗と振動吸収部材１Ｅによる振動減衰性能を発揮しながら、躯体フレーム３や壁パネル４に損傷を与えることなく制振建物２の振動を緩和または収束させることが可能となる。   FIG. 5 shows a vibration absorbing member 1F including an adhesive seal layer 15 having adhesive performance on one side surface of the vibration absorbing member 1D shown in FIG. 3 and a high friction resistance material layer 16 on the other side surface. Yes. For example, the adhesive seal layer 15 and the upper beam 32 or the lower beam 32 are bonded, and the high friction resistance material layer 16 is pressed against the wall panel 4. The high frictional resistance material layer 16 can exhibit frictional resistance performance up to a predetermined peak value, and has a performance that is not peaked when an external force exceeding the peak value is applied and does not exhibit further frictional resistance. With such performance, the relative displacement generated between the frame 3 and the wall panel 4 can be tracked by frictional resistance up to a certain range, and the vibration absorbing member 1E peaks the wall panel 4 beyond the certain range. It becomes restrained only by the frictional resistance. Therefore, the wall panel 4 is deformed while following the deformation of the frame 3 together with the auxiliary frame 5 movably attached to the frame 3. By peak-cutting the frictional resistance at a certain value, the wall panel 4 is not excessively restrained by the housing frame 3 by the vibration absorbing member 1E, and while exhibiting a constant frictional resistance and vibration damping performance by the vibration absorbing member 1E. The vibration of the vibration control building 2 can be reduced or converged without damaging the frame 3 and the wall panel 4.
