Description

本発明は、吊り天井構造体の制振方法及び制振装置に係わり、更に詳しくは非耐震性の吊り天井構造体とフロア構造体間に制振機能を備えたパネル構造体を設置して地震時における吊り天井構造体の振動を抑制する吊り天井構造体の制振方法及び制振装置に関するものである。   The present invention relates to a vibration damping method and a vibration damping device for a suspended ceiling structure, and more particularly, by installing a panel structure having a vibration damping function between a non-earthquake-resistant suspended ceiling structure and a floor structure. The present invention relates to a vibration damping method and a vibration damping device for a suspended ceiling structure that suppresses vibration of the suspended ceiling structure at the time.

通常、オフィスビル等は、複数のスラブで各階が形成され、上スラブの下面側には吊り天井構造体が構築され、下スラブの上面側にはフロア構造体が構築され、構造壁で囲まれた空間を間仕切装置で適宜に区画されている。通常、吊り天井構造体は、上スラブから垂下した吊支部材(吊りボルト)によって、縦横に張り巡らした天井支持レールを吊下げ状に保持し、該天井支持レールに天井パネルの周囲を係止する構造である。このような吊り天井構造体を有する室内に天井パネルからフロア構造体にわたって、間仕切パネルやドアパネルを組み合わせた間仕切装置を設置する。ここで、間仕切パネルは、天井パネルの下面側で天井支持レールを利用して固定した天レールと、フロア構造体の上面に敷設した地レールとの間に、複数の支柱を立設するとともに、隣接する支柱間にパネル板を装着して構成する。   Normally, an office building or the like is formed of a plurality of slabs and each floor is formed, a suspended ceiling structure is constructed on the lower surface side of the upper slab, and a floor structure is constructed on the upper surface side of the lower slab and surrounded by a structural wall. The space is appropriately partitioned by a partition device. In general, a suspended ceiling structure holds a ceiling support rail suspended vertically and horizontally by suspension support members (suspending bolts) suspended from an upper slab, and locks the periphery of the ceiling panel to the ceiling support rail. It is a structure to do. A partition device combining partition panels and door panels is installed in the room having such a suspended ceiling structure from the ceiling panel to the floor structure. Here, the partition panel is provided with a plurality of support columns standing between a ceiling rail fixed using a ceiling support rail on the lower surface side of the ceiling panel and a ground rail laid on the upper surface of the floor structure, A panel board is mounted between adjacent columns.

従来、吊り天井構造体に対する耐震基準はなく、東日本大震災によって多くの吊り天井構造体が落下し、破損したことを受けて、天井の耐震性を高める機運が高まっている。従来の吊り天井構造体は、天井支持レール及び天井パネルの端部が建物の構造壁面と殆ど隙間なく接しており、建物が地震で変形した際に、天井支持レール及び天井パネルの端部が壁面に激しく衝突して破損するとともに、吊り天井構造体の水平方向変位も大きく、そのため吊り天井構造体の下に設けた間仕切パネルも端部が損傷する。特に、長周期振動による共振現象によって吊り天井構造体が水平方向に大きく変位し、あるいは建物のスラブや壁面とは異なる挙動をすることにより被害が拡大していた。因みに、体育館や劇場等の大型建築物の吊り天井構造体に対しては、吊りボルトにブレースを設けて耐震性を高めるとともに、壁や柱等の構造体と吊り天井構造体との間にクリアランスを設けて天井パネルの端部の破損を防止する等の耐震基準が提案されている。そして、新耐震基準では、層間変位角が1/40、震度7、天井面加速度が2.2Gに耐えることが要求されている。   Conventionally, there is no seismic standard for suspended ceiling structures, and due to the fact that many suspended ceiling structures have been dropped and damaged by the Great East Japan Earthquake, the momentum for improving the earthquake resistance of the ceiling is increasing. In the conventional suspended ceiling structure, the end of the ceiling support rail and the ceiling panel are in contact with the structural wall of the building with almost no gap, and when the building is deformed by an earthquake, the end of the ceiling support rail and the ceiling panel is the wall. The suspended ceiling structure is greatly displaced in the horizontal direction, and the partition panel provided under the suspended ceiling structure is also damaged at the ends. In particular, the suspended ceiling structure is greatly displaced in the horizontal direction due to a resonance phenomenon caused by long-period vibration, or the damage is expanded due to a behavior different from that of a slab or wall of a building. By the way, for suspended ceiling structures of large buildings such as gymnasiums and theaters, bracing is provided on the suspension bolts to improve earthquake resistance and clearance between the structures such as walls and pillars and the suspended ceiling structure Seismic standards have been proposed to prevent damage to the end of the ceiling panel. The new earthquake resistance standard requires that the interlaminar displacement angle is 1/40, the seismic intensity is 7, and the ceiling acceleration is 2.2G.

新設の建築物では、最初から耐震性の吊り天井構造体を構築し、耐震性の吊り天井構造体とフロア構造体との間に耐震性間仕切装置を設置することが理想的である。既設の耐震性能が不足している吊り天井構造体の場合でも、天井裏に入ってブレース等を追加する耐震補強工事を施すことができればよいが、そのような耐震補強工事が困難である場合も多い。   In a new building, it is ideal to construct an earthquake-resistant suspended ceiling structure from the beginning and install an earthquake-resistant partition device between the earthquake-resistant suspended ceiling structure and the floor structure. Even in the case of a suspended ceiling structure that lacks existing seismic performance, it is only necessary to be able to perform seismic retrofitting work that adds braces etc. into the back of the ceiling, but such seismic retrofitting work may be difficult. Many.

建築物の耐震性を高める工夫は各種提供されている。例えば、特許文献1には、多数の透孔を略格子状に設けた鋼板を基板とし、前記鋼板の上下各端部が上下の床スラブに固定された制振壁設置部に設置される制震壁であって、前記鋼板の両側縁部に、上下の各端部をピン接合とした平行維持装置を設けた制震壁の構造が開示されている。更に、フロア内に複数の制震壁を直交した異なる2方向に設ける点も開示されている。   Various devices for improving the earthquake resistance of buildings are provided. For example, in Patent Document 1, a steel plate provided with a large number of through holes in a substantially lattice shape is used as a substrate, and upper and lower ends of the steel plate are installed on a damping wall installation section fixed to upper and lower floor slabs. A structure of a seismic wall, which is a seismic wall and is provided with a parallel maintaining device in which both upper and lower ends are pin-joined at both side edges of the steel plate is disclosed. Further, it is also disclosed that a plurality of damping walls are provided in two different directions orthogonal to each other in the floor.

また、特許文献2には、二つの金属板間を粘弾性体で連結した構造の粘弾性ダンパーが開示され、それをブレースに用いて構成した制振パネルが開示されている。   Further, Patent Document 2 discloses a viscoelastic damper having a structure in which two metal plates are connected by a viscoelastic body, and a damping panel configured by using the viscoelastic damper for a brace.

更に、特許文献3には、建築物を構成する複数の枠材の交差部に取り付けられる振動吸収要素としての板バネ制振ユニットを備えた制振装置であって、前記板バネ制振ユニットは、一方の前記枠材と他方の前記枠材に夫々両端部を固定された少なくとも一枚の湾曲したベースバネ板と、該ベースバネ板の少なくとも一端部に対して一端部を固定配置されると共に該一端部を除いた内側面の少なくとも一部を該ベースバネ板の一面と摺擦可能に積層された少なくとも一枚の第1の摺擦バネ板と、を備え、前記第1の摺擦バネ板は、前記ベースバネ板よりも短尺であることを特徴とする制振装置が開示されている。   Further, Patent Document 3 discloses a vibration damping device including a leaf spring damping unit as a vibration absorbing element attached to an intersection of a plurality of frame members constituting a building, wherein the leaf spring damping unit includes: And at least one curved base spring plate having both ends fixed to the one frame member and the other frame member, and one end portion fixed to at least one end portion of the base spring plate and the one end At least a portion of the inner surface excluding the portion, and at least one first rubbing spring plate that is slidably laminated with one surface of the base spring plate, and the first rubbing spring plate includes: A vibration damping device is disclosed that is shorter than the base spring plate.

しかし、これらの特許文献に記載されたものは、何れも制振パネルを柱や梁あるいはスラブに固定して建築物自体の耐震性を高めるというものであり、吊り天井構造体の横揺れを抑制するという発想ではない。   However, all of those described in these patent documents are to improve the seismic resistance of the building itself by fixing the damping panel to the pillar, beam or slab, and to suppress the rolling of the suspended ceiling structure. It is not the idea of doing.

An intermediate structure 3 having a vibration damping function is installed between the suspension ceiling structure 1 and the rolling structure of the suspended ceiling structure 1 to suppress rolling. Here, the intermediate structure 3 having the vibration damping function is constituted by at least one of the panel structure A, the storage fixture B, and the support frame structure C. In this case, since the direction of the roll due to the earthquake is not fixed, it is necessary to give a vibration damping function to different directions including at least two orthogonal directions by the intermediate structure 3.

図1は、複数の間仕切パネルD,…を用いてフロアを区画し、一部に制振機能を備えたパネル構造体Aを配置した典型的な実施形態を示している。図1中符号Wは壁面である。この実施形態のパネル構造体Aは、通常の間仕切パネルDと同じ外観を有し、内部に制振機能が組み込まれた構造であり、制振方向はパネルの面内方向である。図1には、パネル構造体Aによる制振方向をPとQで示してあり、それらの方向は直交している。少なくともフロアの一定面積において、P方向とQ方向に制振機能を備えたパネル構造体A,Aを配置することにより、地震による横揺れがどの方向に生じても、前記吊り天井構造体1の横揺れを両パネル構造体A,Aが協同して抑制できるのである。   FIG. 1 shows a typical embodiment in which a floor is partitioned using a plurality of partition panels D,... And a panel structure A having a vibration damping function is arranged in part. In FIG. 1, symbol W is a wall surface. The panel structure A of this embodiment has the same appearance as a normal partition panel D and has a structure in which a vibration damping function is incorporated therein, and the vibration damping direction is the in-plane direction of the panel. In FIG. 1, the vibration control directions by the panel structure A are indicated by P and Q, and these directions are orthogonal to each other. By arranging the panel structures A and A having vibration damping functions in the P direction and Q direction at least in a certain area of the floor, the suspended ceiling structure 1 Both panel structures A and A can suppress rolling in cooperation.

ここで、「制振機能を備えた」又は「制振機構を内蔵した」とは、中間構造物3自体に一体的に制振機構を設ける場合と、中間構造物3自体には制振機構を設けていないが、該中間構造物3が作る空間内で制振機構を介して吊り天井構造体1に連結する場合とを含む概念である。本発明の基本構成は、制振機構が組み込まれた中間構造物3の上下端を吊り天井構造体1とフロア構造体2に固定するものと、剛性の高い中間構造物3の下端をフロア構造体2に固定するとともに、該中間構造物3の上端を吊り天井構造体1に制振機構を介して連結するものがある。   Here, “provided with a damping function” or “built-in damping mechanism” means that a vibration damping mechanism is provided integrally with the intermediate structure 3 itself, and a vibration damping mechanism is provided in the intermediate structure 3 itself. However, it is a concept including a case where the intermediate structure 3 is connected to the suspended ceiling structure 1 via a vibration control mechanism in the space formed by the intermediate structure 3.

図4(a)は、パネル構造体Aの他の実施形態を示し、通常構造の間仕切パネルAの支柱6に制振機構を組み込んだような構造である。本実施形態のパネル構造体Aは、前記吊り天井構造体1の下面に取付けた天レール4と前記フロア構造体2の上面に取付けた地レール5との間に、複数の支柱6,…を所定間隔を隔てて立設するとともに、該支柱6を用いて表裏両面にパネル板7,…を装着し、各支柱6の下端を前記地レール5に固定するとともに、上端を前記天レール4に対して面内変位可能に保持し、前記支柱6,…のうち少なくとも1つの前記支柱6の上部両側と前記天レール4を介して吊り天井構造体1に固定した天ブラケット9,9間を傾斜状態に配置した粘弾性ダンパー10,10で連結した構造である。具体的には、前記支柱6の両側に天ブラケット9,9を取付け、該支柱6の上部両側に支柱ブラケット11,11を側設し、それぞれの側で天ブラケット9と支柱ブラケット11とを傾斜状態に配置した前記粘弾性ダンパー10で連結している。   Fig.4 (a) shows other embodiment of the panel structure A, and is a structure which incorporated the damping mechanism in the support | pillar 6 of the partition panel A of a normal structure. The panel structure A of the present embodiment includes a plurality of support columns 6,... Between a ceiling rail 4 attached to the lower surface of the suspended ceiling structure 1 and a ground rail 5 attached to the upper surface of the floor structure 2. The panel plates 7 are mounted on both the front and back surfaces by using the support posts 6 to fix the lower ends of the support posts 6 to the ground rail 5 and the upper ends to the top rail 4. The upper brackets 9 and 9 fixed to the suspended ceiling structure 1 via the top rail 4 and the upper both sides of at least one of the columns 6... It is the structure connected with the viscoelastic dampers 10 and 10 arrange | positioned in the state. Specifically, the top brackets 9 and 9 are attached to both sides of the column 6, the column brackets 11 and 11 are provided on both sides of the top of the column 6, and the ceiling bracket 9 and the column bracket 11 are inclined on each side. The viscoelastic dampers 10 arranged in a state are connected.

図4(b)に示したパネル構造体Aは、図4(a)の構造に加えて、前記支柱6の両側に地ブラケット13,13を取付け、前記支柱6の下部両側に支柱ブラケット11,11を側設し、それぞれの側で地ブラケット13と支柱ブラケット11とを傾斜状態に配置した前記粘弾性ダンパー10で連結した構造である。その他の構成は、図4(a)に示した構成と同じであるので、同一構成には同一符号を付してその説明は省略する。   In addition to the structure shown in FIG. 4A, the panel structure A shown in FIG. 4B is provided with ground brackets 13 and 13 on both sides of the column 6 and column brackets 11 and 13 on both sides below the column 6. 11, the ground bracket 13 and the column bracket 11 are connected to each other by the viscoelastic damper 10 arranged in an inclined state.

The vibration energy is absorbed by the deformation of the body 18. In other words, the horizontal displacement caused by the earthquake causes an interlayer displacement in the vertical slab. At this time, the column 6 tilts with respect to the suspended ceiling structure 1, pulls one viscoelastic damper 10 and compresses the other viscoelastic damper 10. As a result, the viscoelastic body 18 of each viscoelastic damper 10 is deformed and absorbs the energy of rolling. As a result, the rolling of the suspended ceiling structure 1 can be suppressed, and damage and collapse can be prevented.

そこで、図16に示すように、断面コ字形の前記天レール4の上面板45に正方形の4辺に対応する位置に4つのスリット46,…を形成するとともに、その内方に単又は複数の貫通孔47を形成した。そして、新たに剣山金物48を作製した。前記剣山金物48は、正方形の基板49の4辺に直角に爪片50,…を立起させるとともに、基板49に対角線上に4つの取付孔51,…を形成した構造である。前記岩綿吸音板43の下面に天レール4の上面板45を沿わせた状態で、下方から前記剣山金物48の爪片50,…を、前記スリット46,…を通して前記岩綿吸音板43に突き刺し、前記ネジ44を剣山金物48の取付孔51と天レール4の貫通孔47を通して前記天井支持レール40に螺合するのである。ここで、本発明の中間構造物3を設ける位置の前後を含めて対応する領域では、前記天レール4を前記ネジ44と剣山金物48とのセットで、密に等間隔で吊り天井構造体1に固定し、横揺れによる荷重を分散させる。例えば、一枚の前記パネル構造体Aに対して10箇所で天レール4を吊り天井構造体1に固定する。   Therefore, as shown in FIG. 16, four slits 46,... Are formed at positions corresponding to the four sides of the square on the top plate 45 of the top rail 4 having a U-shaped cross section, and one or a plurality of slits 46 are formed on the inside thereof. A through hole 47 was formed. Then, a new Kenyama hardware 48 was produced. The sword mountain hardware 48 has a structure in which claw pieces 50 are vertically raised on four sides of a square substrate 49 and four attachment holes 51 are formed on the substrate 49 diagonally. With the upper surface plate 45 of the top rail 4 along the lower surface of the rock wool sound absorbing plate 43, the claw pieces 50,... Of the sword mountain hardware 48 are passed from below to the rock wool sound absorbing plate 43 through the slits 46,. The screw 44 is screwed into the ceiling support rail 40 through the mounting hole 51 of the sword mountain hardware 48 and the through hole 47 of the top rail 4. Here, in the corresponding region including before and after the position where the intermediate structure 3 according to the present invention is provided, the ceiling rail 4 is a set of the screw 44 and the sword mountain hardware 48, and is suspended from the ceiling structure 1 closely at equal intervals. The load due to rolling is distributed. For example, the ceiling rail 4 is fixed to the suspended ceiling structure 1 at ten locations with respect to one panel structure A.
