Description
【０００１】[0001]
この考案は、免震構造部の床板と非免震構造部の床板との間に掛け渡す緩衝板 の取付け構造に関する。 The present invention relates to a mounting structure for a buffer plate that is hung between a floor plate of a base isolation structure and a floor plate of a non-seismic isolation structure.
【０００２】[0002]
建物の全体を免震構造にすると免震装置が過大となるために、建物の一部のみ を免震構造として重要機器を設置し、他の部分は非免震構造とすることがある。 この場合、免震構造部の床板と非免震構造部の床板との間には緩衝板が掛け渡さ れるが、地震時の揺れが両構造部で異なるから、緩衝板は両構造部の揺れの相違 を吸収できる取付け構造とする必要がある。 このような緩衝板の取付け構造としては実願平３−８０４８３号があり、これ は、免震構造部の床板の端部に受け金物を固定し、該受け金物と係合する固定金 物を一端に固定した緩衝板を非免震構造部の床板の上面に掛け渡した取付け構造 において、前記受け金物を外方に張り出した後に上方に立ち上がる形状に形成し 、前記固定金物を受け金物に嵌入する箱型に形成した構造である。 If the entire building is seismically isolated, the seismic isolation device will be too large. Therefore, only a part of the building may have seismic isolation structure and important equipment may be installed, while the other parts may have a seismic isolation structure. In this case, a buffer plate is laid between the floor plate of the base-isolated structure part and the floor plate of the non-base-isolated structure part.However, since the shaking at the time of an earthquake is different in both structural parts, the buffer plate is the shaking of both structural parts. It is necessary to have a mounting structure that can absorb the difference in. Japanese Patent Application No. 3-80483 discloses a mounting structure for such a buffer plate, which fixes a receiving member to the end of the floor plate of the base isolation structure and mounts a fixing member that engages with the receiving member. In a mounting structure in which a buffer plate fixed at one end is hung on the upper surface of the floor plate of the non-seismic isolation structure, the receiving hardware is formed so that it extends outward and then rises upward, and the fixed hardware is fitted into the receiving hardware. It has a box-shaped structure.
【０００３】[0003]
上記従来の緩衝板の取付け構造では、水平動についてはこれを吸収することが できるが、凹字状に形成された受け金物に箱型の固定金物が嵌入しているから、 非免震構造部が上方に移動したときには固定金物と緩衝板との固定部に過大な応 力が作用して、該固定部の破損を招くおそれがある。一応の目安として水平動を ２００〜３００ｍｍの移動巾、また上下動として２０〜３０ｍｍの移動高さを目 標にしている。 したがって本考案は、垂直動を含む地震動を吸収することができる緩衝板の取 付け構造を提供することを目的とする。 The above conventional buffer plate mounting structure can absorb horizontal movement, but since the box-shaped fixed metal fitting is fitted into the concave-shaped receiving metal fitting, the non-seismic isolation structure part When is moved upward, an excessive force may act on the fixed portion between the fixed metal member and the buffer plate, and the fixed portion may be damaged. As a rough guide, horizontal movement is set to a movement width of 200 to 300 mm, and vertical movement is set to a movement height of 20 to 30 mm. Therefore, it is an object of the present invention to provide a mounting structure for a buffer plate that can absorb earthquake motion including vertical motion.

【課題を解決するための手段】 本考案は上記目的を達成するためになされたものであり、すなわち、免震構造 部の床板と非免震構造部の床板とのいずれか一方の床板の端部に受け金物を固定 し、該受け金物と係合する固定金物を一端に固定した緩衝板を前記いずれか他方 の床板の上面に掛け渡した免震床構造において、前記受け金物は、外方に張り出 した後に上方に立ち上がる形状に形成され、前記固定金物は、下方に向って外方 に傾斜する傾斜面を有することを特徴とする免震床構造である。Means for Solving the Problems The present invention has been made to achieve the above-mentioned object, that is, one of the floor plate of the base-isolated structure part and the floor plate of the non-seismic-isolated structure part ends. In a seismic isolation floor structure in which a receiving member is fixed to a portion, and a buffer plate having one end fixed with a fixing member that engages with the receiving member is hung over the upper surface of the other floor plate, the receiving member is an outward The seismic isolation floor structure is characterized in that it is formed in a shape that rises upward and then rises upward, and that the fixed hardware has an inclined surface that inclines outward toward the downward direction.
【０００５】[0005]
受け金物は外方に張り出した後に上方に立ち上がっているのに対して、固定金 物は傾斜面を有するから、前記いずれか他方の床板が上方に移動したときにも、 固定金物を固定した緩衝板は無理なく回転することができ、したがって固定金物 と緩衝板との固定部に過大な応力は作用しない。 また地震動が止んだときには、固定金物とこれを取り付けた緩衝板は、固定金 物の傾斜面に沿って滑落するから、自然に原形状に復帰する。 The receiving metal object rises upward and then rises upward, whereas the fixed metal object has an inclined surface, and therefore, even when one of the above-mentioned other floor plates moves upward, the fixed metal object buffers. The plate can rotate without difficulty, and therefore, excessive stress does not act on the fixed portion between the fixed metal member and the buffer plate. When the earthquake motion stops, the fixed hardware and the cushioning plate to which it is attached slide down along the inclined surface of the fixed metal and naturally return to the original shape.

本考案の一実施例を図面によって説明する。図１に示されているごとく、建物 の床スラブ１上の壁２際には、非免震部支持脚３を介してボーダー部床板４が固 定されている。他方、建物の床スラブ１上には、図示しない免震装置を介して免 震部構造部材５が設けられており、この免震部構造部材５上に、免震部支持脚６ を介して免震部床板７が固定されている。この免震部床板７上には、電子計算機 、その他の重要機器（図示せず）が載置される。免震部支持脚６のうち最外周の ものには受け金物８が固定されており、この受け金物８に固定金物９が係合して いる。固定金物９は緩衝板１０に固定されており、緩衝板１０の先端（図面左端 をいう。以下同じ。）はボーダー部床板４の上面に掛け渡されている。 An embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, a border floor plate 4 is fixed to the wall 2 on the floor slab 1 of the building through the non-seismic isolation support legs 3. On the other hand, a seismic isolation part structural member 5 is provided on the floor slab 1 of the building via a seismic isolation device (not shown), and on this seismic isolation part structural member 5 via seismic isolation part support legs 6. The base plate 7 of the seismic isolation unit is fixed. An electronic computer and other important devices (not shown) are placed on the base plate 7 of the seismic isolation unit. A receiving metal object 8 is fixed to the outermost one of the seismic isolation part support legs 6, and a fixing metal object 9 is engaged with the receiving metal object 8. The fixed hardware 9 is fixed to the buffer plate 10, and the tip of the buffer plate 10 (referred to as the left end in the drawing; the same applies below) is laid over the upper surface of the border floor plate 4.
【０００７】 受け金物８は、図２に示されているごとく、内板部８ａと底板部８ｂと外板部 ８ｃと上板部８ｄとをその順に直角に折り曲げた形状をなし、アルミ合金の押し 出し成形によって形成されている。内板部８ａの上端面は免震部床板７の上面と 面一に形成されており、底板部８ｂにおいて免震部支持脚６にビス止めされてお り、外板部８ｃの高さは内板部８ａの高さよりも低い。また上板部８ｄの幅は底 板部８ｂの幅よりも狭く、したがって上板部８ｄの端面と内板部８ａとの間に固 定金物９を挿入すべき間隙が形成されている。 固定金物９は、上板部９ａと傾斜部９ｂと垂直部９ｃと下板部９ｄとをその順 に折り曲げた形状をなし、アルミ合金の押し出し成形によって形成されている。 また上板部９ａと傾斜部９ｂとの境界に、受け金物の上板部８ｄの内側端部が当 接する垂直面９ｅが形成されており、上板部９ａにおいて緩衝板１０にビス止め されている。緩衝板１０の上面は免震部床板７の上面と面一に形成されており、 下面はボーダー部床板４の上面と面一に形成されている。As shown in FIG. 2, the receiving member 8 has a shape in which an inner plate portion 8a, a bottom plate portion 8b, an outer plate portion 8c, and an upper plate portion 8d are bent at right angles in that order, and is made of an aluminum alloy. It is formed by extrusion. The upper end surface of the inner plate portion 8a is formed flush with the upper surface of the base plate 7 of the seismic isolation portion, and the bottom plate portion 8b is screwed to the support leg 6 of the seismic isolation portion, and the height of the outer plate portion 8c is It is lower than the height of the inner plate portion 8a. Further, the width of the upper plate portion 8d is narrower than the width of the bottom plate portion 8b, so that there is formed a gap between the end surface of the upper plate portion 8d and the inner plate portion 8a in which the fixed metal product 9 should be inserted. The fixed hardware 9 has a shape in which an upper plate portion 9a, an inclined portion 9b, a vertical portion 9c, and a lower plate portion 9d are bent in that order, and is formed by extrusion molding of an aluminum alloy. At the boundary between the upper plate portion 9a and the inclined portion 9b, a vertical surface 9e with which the inner end portion of the upper plate portion 8d of the receiving member contacts is formed, and is screwed to the buffer plate 10 at the upper plate portion 9a. There is. The upper surface of the cushioning plate 10 is formed flush with the upper surface of the base isolation floorboard 7, and the lower surface is formed flush with the upper surface of the border floorboard 4.
【０００８】 本実施例は以上のように構成されており、地震のない通常状態において、緩衝 板１０の免震部床板７側への移動については、緩衝板１０の端面が受け金物８の 内板部８ａに当接し、緩衝板１０のボーダー部床板４側への移動については、固 定金物の垂直面９ｅが受け金物の上板部８ｄに当接するから、緩衝板１０は左右 方向にガタつくことがない。また前後方向には隣接する緩衝板があるから、前後 方向にもガタつくことがない。The present embodiment is configured as described above, and in a normal state without an earthquake, with respect to the movement of the buffer plate 10 to the base isolation floor plate 7 side, the end surface of the buffer plate 10 is inside the receiving member 8. With respect to the movement of the buffer plate 10 toward the border part floor plate 4 side while contacting with the plate portion 8a, since the vertical surface 9e of the fixed metal member contacts the upper plate portion 8d of the receiving metal member, the buffer plate 10 is rattled in the left and right direction. I can't get it. Also, since there are adjacent cushion plates in the front-back direction, there is no rattling in the front-back direction.
【０００９】 しかして地震動が生じると、免震部床板７とボーダー部床板４とは異なる動き をなす。先ずボーダー部床板４が水平動、すなわち前後動又は左右動をしたとき には、緩衝板１０の下面とボーダー部床板４の上面とが摺動するだけであって、 特段の問題を生じない。 次に上下動のうち、ボーダー部床板４が下降したときには、図３に示すごとく 緩衝板１０は反時計方向に僅かに回転しつつその先端がボーダー部床板４の上面 に当接し、こうして緩衝板１０はボーダー部床板４の下降に無理なく追従するこ とができる。この状態で更に水平動が加重しても、緩衝板１０の先端とボーダー 部床板４の上面とが摺動するだけであって、なおも地震動に追随することができ る。Then, when an earthquake motion occurs, the base isolation floorboard 7 and the border floorboard 4 move differently. First, when the border part floor plate 4 horizontally moves, that is, moves back and forth or left and right, only the lower surface of the buffer plate 10 and the upper surface of the border part floor plate 4 slide and no particular problem occurs. Next, in the vertical movement, when the border part floor plate 4 descends, the buffer plate 10 slightly rotates counterclockwise as shown in FIG. 3 and its tip comes into contact with the upper surface of the border part floor plate 4, and thus the buffer plate 10 10 can reasonably follow the lowering of the border floor plate 4. Even if horizontal motion is further applied in this state, only the tip of the buffer plate 10 and the upper surface of the border floor plate 4 slide, and the seismic motion can still be followed.
【００１０】 他方上下動のうち、ボーダー部床板４が上昇したときには次のようになる。す なわちもしも緩衝板１０と固定金物との重心Ｇが、ボーダー部床板４の先端（図 面右端をいう。以下同じ。）よりも図面左側にあるときには、緩衝板１０の全体 がボーダー部床板４によって単に持ち上げられ、すなわち緩衝板１０はボーダー 部床板４の動きに追従する。この状態で更に水平動が加重されても、緩衝板１０ はボーダー部床板４によって持ち上げられたまま水平移動するだけであって、な おも地震動に追随することができる。On the other hand, of the vertical movements, when the border part floorboard 4 is raised, the following occurs. That is, when the center of gravity G between the buffer plate 10 and the fixed hardware is on the left side of the drawing with respect to the tip of the border floor plate 4 (the right end of the drawing; the same applies below), the entire buffer plate 10 is the floor plate of the border part. 4 is simply lifted, that is, the buffer plate 10 follows the movement of the border floor plate 4. Even if horizontal motion is further applied in this state, the buffer plate 10 only moves horizontally while being lifted by the border part floor plate 4, and can mainly follow seismic motion.
【００１１】 但し本実施例では緩衝板１０と固定金物との重心Ｇが、ボーダー部床板４の先 端よりも図面右側にあるために、図４に示すごとくボーダー部床板４の先端が緩 衝板１０の下面に当接しつつ緩衝板１０を時計方向に僅かに回転させ、こうして 緩衝板１０はボーダー部床板４の上昇に無理なく追従する。この状態で更に前後 動が加重しても、特段の変化は生じない。他方、左右動が加重すると、緩衝板１ ０の回転角度が変化して、なおも地震動に追随する。ボーダー部床板４の先端が 、図５に示すごとく緩衝板１０と固定金物との重心Ｇを越えて図面右側に移動し たときには、緩衝板１０と受け金物８との摩擦、及び固定金物９と受け金物８と の摩擦がなければ、緩衝板１０は一気に倒伏してボーダー部床板４上に倒れるが 、実際には上記摩擦があるために、緩衝板１０の回転角度が一層増す。その後ボ ーダー部床板４の右方向への移動が止んで左方向への移動に変わると同時に、図 ６に示すごとく緩衝板１０は一気に倒伏してボーダー部床板４上に倒れる。However, in this embodiment, since the center of gravity G between the buffer plate 10 and the fixed hardware is on the right side of the drawing with respect to the front end of the border floor plate 4, the tip of the border floor plate 4 is relaxed as shown in FIG. The buffer plate 10 is slightly rotated clockwise while being in contact with the lower surface of the plate 10, so that the buffer plate 10 naturally follows the rise of the border floor plate 4. In this state, even if the forward / backward movement is further weighted, no particular change occurs. On the other hand, when the lateral movement is weighted, the rotation angle of the buffer plate 10 changes and still follows the earthquake motion. When the tip of the border floor plate 4 moves to the right side of the drawing beyond the center of gravity G between the buffer plate 10 and the fixed hardware as shown in FIG. 5, the friction between the buffer plate 10 and the receiving metal 8 and the fixed hardware 9 If there is no friction with the receiving object 8, the cushioning plate 10 will fall at a stretch and fall on the border floor plate 4, but in reality, due to the friction, the rotation angle of the cushioning plate 10 is further increased. After that, the movement of the floor part 4 of the boarder part to the right stops and the movement to the left part is changed, and at the same time, as shown in FIG. 6, the buffer plate 10 lays down at once and falls on the floor part 4 of the border part.
【００１２】 以上のように地震動がいかように作用しようとも、緩衝板１０はボーダー部床 板４の動きに追随する。最終的に地震動が止んだときには、固定金具の傾斜部９ ｂの下面が傾斜面９ｆとなっているために、固定金物９を取り付けた緩衝板１０ は、この傾斜面９ｆに沿って滑落するから、自然に原形状に復帰する。As described above, the buffer plate 10 follows the movement of the border floor plate 4 regardless of how the earthquake motion acts. When the seismic motion finally stops, since the lower surface of the inclined portion 9b of the fixing bracket is the inclined surface 9f, the buffer plate 10 to which the fixed hardware 9 is attached slides down along the inclined surface 9f. , Naturally returns to its original shape.
【００１３】 なお受け金物の内板部８ａと固定金物の垂直部９ｃは、特に設けない構成とす ることもできる。また固定金物の傾斜部９ｂのうち、傾斜面９ｆと反対側の面の 形状は特に問題とならない。 また固定金物の垂直面９ｅを設けない構成とすることもできるが、固定金物９ の横方向の寸法精度を高めるためにこれを設けて、受け金物の上板部８ｄ上面と 固定金物の上板部９ａ下面とのメタルタッチの確実を期することが好ましい。 また受け金物の上板部８ｄと固定金物の下板部９ｄとは、これを設けない構成 とすることもできるが、緩衝板１０のバウンドなどの事態を想定して、これを設 けて固定金物９が受け金物８から脱落しにくくすることが好ましい。なお受け金 物の上板部８ｄを設けない構成としたときには、固定金物の垂直面９ｅは受け金 物の外板部８ｄの内側端部に当接することとなる。The inner plate portion 8a of the receiving metal object and the vertical portion 9c of the fixed metal object may be configured not to be provided. Further, of the inclined portion 9b of the fixed metal object, the shape of the surface on the opposite side of the inclined surface 9f does not matter. Further, the vertical surface 9e of the fixed metal object may be omitted, but it is provided in order to improve the dimensional accuracy of the fixed metal object 9 in the lateral direction, and the upper surface 8d of the receiving metal object and the upper plate of the fixed metal object are provided. It is preferable to ensure the metal touch with the lower surface of the portion 9a. Further, the upper plate portion 8d of the receiving metal object and the lower plate portion 9d of the fixed metal object may be configured not to be provided, but in consideration of a situation such as the bounce of the buffer plate 10, it is fixed and fixed. It is preferable that the hardware 9 is less likely to fall off the receiving metal 8. When the upper plate portion 8d of the receiving member is not provided, the vertical surface 9e of the fixed metal member comes into contact with the inner end of the outer plate portion 8d of the receiving metal member.
【００１４】 また本実施例では、受け金物８を免震構造部側に取り付けて緩衝板１０を非免 震構造部側に掛け渡した場合を示したが、受け金物８を非免震構造部側に取り付 けて、緩衝板１０を免震構造部側に掛け渡すこともできる。また本実施例では各 床板４，７を各支持脚３，６で支持したフリーアクセスフロアの場合を示したが 、フリーアクセスフロアでない床面に本考案を適用することもできる。さらに緩 衝板１０を１枚ものを示しているが、下方向のみに曲がる例えば蝶番のようなも ので、緩衝板の一方がハネ上らないように屈曲することも可能である（図５点線 ）。Further, in the present embodiment, the case where the receiving object 8 is attached to the seismic isolation structure side and the buffer plate 10 is hung over the non-seismic isolation structure side is shown. It is also possible to mount it on the side and hang the buffer plate 10 on the seismic isolation structure side. Further, in the present embodiment, the case of the free access floor in which the floor plates 4 and 7 are supported by the support legs 3 and 6 is shown, but the present invention can be applied to the floor surface which is not the free access floor. Furthermore, although only one cushion plate 10 is shown, it can be bent only in the downward direction, for example, like a hinge, so that it is possible to bend one of the cushion plates so that it will not rise (see dotted line in FIG. 5). ).
【００１５】[0015]
本考案によれば、受け金物は外方に張り出した後に上方に立ち上がっているの に対して、固定金物は傾斜面を有するから、固定金物を固定した緩衝板は無理な く回転することができ、したがって固定金物と緩衝板との固定部に過大な応力は 作用しない。また地震動が止んだときには、固定金物とこれを取り付けた緩衝板 は、固定金物の傾斜面に沿って滑落するから、自然に原形状に復帰する。 According to the present invention, the receiving metal object is projected outward and then rises upward, whereas the fixed metal object has an inclined surface, so that the buffer plate to which the fixed metal object is fixed can rotate without difficulty. Therefore, excessive stress does not act on the fixed part between the fixed hardware and the buffer plate. Also, when the earthquake motion stops, the fixed hardware and the cushioning plate to which it is attached slide down along the inclined surface of the fixed hardware, and thus naturally return to the original shape.
