Description
【０００１】 イ．考案の目的 (1) 産業上の利用分野 この考案は、建築物等の上部構造と基台等の下部構造との間に介装され、常時 は上部構造を支持し、地震動等に対しその介装体のもつ揺動作用により上部構造 の揺れを低減する免震支持装置に関し、特には、木造家屋、低層コンクリ−ト構 造物等の軽荷重構造物に用いて好適ないわゆる軽荷重用免震支持装置に関する。B. Purpose of the invention (1) Industrial field of application This invention is installed between an upper structure such as a building and a lower structure such as a base, always supports the upper structure, and supports it against earthquake motion. The present invention relates to a seismic isolation support device that reduces the shaking of the upper structure by the swinging action of the body, and is particularly suitable for light load seismic isolation suitable for light load structures such as wooden houses and low-rise concrete structures. Regarding support device.
【０００２】 (2) 従来の技術 この種の軽荷重用免震支持装置において、介装体として球体を使用した特許第 ６１１３５号公報のものが公知である。 該公知技術によれば、建築物の基礎上にその凹球面部を上に向けて設置した皿 形盤と建築物の台材にその凹球面部を下に向けて設置した皿形盤との間に球体を 介装させてなる構成を採る。 しかして、この構成により、地震の発生で基礎が前後・左右動したとき、球体 が上下の凹球面部間を転動し、台材にその揺れを伝えず、建築物は静止状態を保 持し、建築物の破損を防止するという作用効果を奏するものである。 しかしながら、該公知技術によれば、球体は点接触により建築物を支持するた めに荷重支持能力が小さく、また、経年変化により球面表面の錆などにより性能 低下が著しいという問題がある。更に、この公知技術の構成のみでは地震エネル ギーを減衰する機能を備えておらず、別途ダンパーを設置する必要があり、設置 費用が嵩むという問題もある。(2) Conventional Technique In this type of seismic isolation support device for light load, there is known one disclosed in Japanese Patent No. 61135 which uses a sphere as an interposer. According to the known technique, a dish-shaped board having its concave spherical surface portion placed on the foundation of a building and a dish-shaped board having its concave spherical surface portion placed on the base of a building are placed downward. A structure with a sphere in between is adopted. With this configuration, when the foundation moves back and forth and left and right due to the occurrence of an earthquake, the sphere rolls between the upper and lower concave spherical parts, the sway is not transmitted to the base material, and the building remains stationary. However, it has the effect of preventing damage to the building. However, according to the known technique, the spherical body has a problem that the load supporting ability is small because the spherical body supports the building by point contact, and the performance deteriorates remarkably due to aging of the spherical surface due to aging. Furthermore, the structure of this known technology alone does not have a function of attenuating seismic energy and requires a separate damper to be installed, which causes a problem of increased installation cost.
【０００３】 (3) 考案が解決しようとする問題点 本考案は上記実情に鑑みなされたものであり、この種の軽荷重用免震支持装置 において、介装体に着目し、荷重支持能力が大きく、別途にダンパーを設ける必 要のない軽荷重用免震支持装置を提供することを目的とするものである。(3) Problems to be Solved by the Invention The present invention has been made in view of the above circumstances, and in this type of light load seismic isolation support device, attention is paid to the interposer, and the load support ability is It is intended to provide a seismic isolation support device for light loads that is large and does not require a separate damper.
【０００４】 ロ. 考案の構成 (1) 問題点を解決するための手段 本考案の軽荷重用免震支持装置は上記目的を達成するため、次の技術的手段（ 構成）を採る。すなわち、下部構造に固定されるとともに上方に向けて凹球面に 形成された球面座を有する下沓と、上部構造に固定されるとともに下方に向けて 凹球面に形成された球面座を有する上沓と、前記上沓と下沓との間に介装され、 その上面のすべり面を上沓の球面座の曲率に合致し、その下面のすべり面を下沓 の球面座の曲率に合致し、実質的に円柱形状をなす摺動子と、からなることを特 徴とする。B. Structure of the Invention (1) Means for Solving Problems The light load seismic isolation support device of the invention adopts the following technical means (structure) to achieve the above object. That is, a lower shoe having a spherical seat that is fixed to the lower structure and is formed as a concave spherical surface upward, and an upper shoe that is fixed to the upper structure and has a spherical seat formed as a concave spherical surface downward. , And is interposed between the upper shoe and the lower shoe, the upper surface of the slip surface matches the curvature of the upper shoe spherical seat, and the lower surface of the slip surface matches the lower shoe spherical seat, It is characterized in that it comprises a slider having a substantially cylindrical shape.
【０００５】 (2) 作用 摺動子は上下面とも面接触をなし、上部構造の荷重を面的に支持し、大きな荷 重支持能力を発揮する。 地震により下部構造が水平振動すると、摺動子は上沓と下沓のそれぞれの球面 座間を摺動移動し、下部構造の変位に追従することはない。これにより、下沓の 変位を上沓に伝達させない。 摺動子の上下面は、上沓及び下沓の球面座に面接触し、その摩擦抵抗力により 減衰作用を奏する。(2) Action The slider makes surface contact with the upper and lower surfaces, supports the load of the superstructure in a plane, and exerts a large load supporting ability. When the substructure vibrates horizontally due to an earthquake, the slider slides between the spherical seats of the upper and lower shoes and does not follow the displacement of the substructure. This prevents the displacement of the lower shoe from being transmitted to the upper shoe. The upper and lower surfaces of the slider come into surface contact with the spherical seats of the upper and lower shoes, and the frictional resistance force exerts a damping action.
【０００６】 (3) 実施例 本考案の軽荷重用免震支持装置の実施例を図面に基づいて説明する。 図１〜図３はその一実施例を示す。すなわち、図１はこの軽荷重用免震支持装 置が適用される構造系の全体を示し、図２及び図３はその要部の構造を示す。(3) Embodiment An embodiment of the seismic isolation support device for a light load of the present invention will be described with reference to the drawings. 1 to 3 show an embodiment thereof. That is, Fig. 1 shows the entire structural system to which the seismic isolation support device for light loads is applied, and Figs. 2 and 3 show the structure of the main part thereof.
【０００７】 図において、Ｂは基台等の下部構造であり、Ｇは建築物等の上部構造であり、 本軽荷重用免震支持装置Ｓはこれらの下部構造Ｂと上部構造Ｇとの間に介装され 、上部構造Ｇの荷重を下部構造Ｂに伝達するとともに両者間の水平方向の相対的 変位を許容する。In the drawing, B is a lower structure such as a base, G is an upper structure such as a building, and the present seismic isolation support device S for light load is provided between the lower structure B and the upper structure G. The upper structure G transfers the load of the upper structure G to the lower structure B and allows relative displacement in the horizontal direction between the two.
【０００８】 本軽荷重用免震支持装置Ｓはこのため、下部構造Ｂ上に載置固定される下沓１ と、上部構造Ｇの下面に固定される上沓２と、これらの下沓１及び上沓２間に介 装される摺動子３とからなる。Therefore, the seismic isolation support device S for light loads has a lower shoe 1 mounted and fixed on the lower structure B, an upper shoe 2 fixed on the lower surface of the upper structure G, and the lower shoe 1 And a slider 3 interposed between the upper shoe 2.
【０００９】 以下、各部の構成を詳述する。 下沓１は円柱状体５を基体として、その下辺の四隅に開設されたアンカーボル ト挿通孔１ａを介して下部構造Ｂに埋設されたアンカーボルト６にナット７を締 め込んで固設される。Ｄは円柱状体５の差渡し径である。 そして、該下沓１の上面部には所定の曲率Ｒをもって上方に向けて凹球面に形 成された下部球面座８が凹設されている。The configuration of each unit will be described in detail below. The lower shoe 1 has a cylindrical body 5 as a base body, and is anchored by anchoring nuts 7 to anchor bolts 6 embedded in the lower structure B through anchor bolt insertion holes 1a formed at the four corners of the lower side thereof. It D is the delivery diameter of the cylindrical body 5. A lower spherical seat 8 is formed on the upper surface of the lower shoe 1. The lower spherical seat 8 has a predetermined curvature R and is upwardly formed into a concave spherical surface.
【００１０】 上沓２は下沓１と同様に円柱状体１０を基体とし、その上辺に開設されたボル ト挿通孔を介して、ボルト・ナットの締結手段により上部構造Ｇに固設される。 図例では円柱状体１０の径は下沓１の円柱状体５の径Ｄに等しくされているが、 それに限定されるものではない。 そして、該上沓２の下面部には、所定の曲率ｒをもって下方に向けて凹球面に 形成された上部球面座１１が凹設されている。Similar to the lower shoe 1, the upper shoe 2 has a columnar body 10 as a base body, and is fixed to the upper structure G by bolt and nut fastening means through a bolt insertion hole formed on the upper side thereof. .. In the illustrated example, the diameter of the cylindrical body 10 is made equal to the diameter D of the cylindrical body 5 of the lower shoe 1, but the diameter is not limited to that. The lower surface of the upper shoe 2 is provided with an upper spherical seat 11 which has a predetermined curvature r and is formed in a downward spherical concave surface.
【００１１】 摺動子３は所定の径と所定の高さを有する円柱体をなし、その下面部には下沓 １の球面座８と同一曲率Ｒの球面部１３が形成され、上面部には上沓２の球状面 １１と同一曲率ｒの球面部１４が形成される。 この摺動子３の直径ｄは、荷重を支持するに必要な大きさを確保されるが、下 沓１及び上沓２の円柱状体５，１０の差渡し径Ｄよりも十分に小さく、後記する 摺動子３の摺動動作において十分な移動域を保持する。 また、該摺動子３の高さは、下沓１及び上沓２の球面座８，１１間の最大距離 をなす位置に介装された状態、すなわち、下沓１と上沓２とが同一位相で球面座 ８，１１の中心間の距離で、下沓１と上沓２とが接触しないような高さとされる 。The slider 3 is a columnar body having a predetermined diameter and a predetermined height, a spherical surface portion 13 having the same curvature R as the spherical seat 8 of the lower shoe 1 is formed on the lower surface portion, and the upper surface portion is formed on the upper surface portion. A spherical portion 14 having the same curvature r as the spherical surface 11 of the upper shoe 2 is formed. The diameter d of the slider 3 is ensured to be large enough to support the load, but is sufficiently smaller than the delivery diameter D of the cylindrical bodies 5 and 10 of the lower shoe 1 and the upper shoe 2, A sufficient range of movement is maintained in the sliding movement of the slider 3 described later. In addition, the height of the slider 3 is such that the slider 3 is interposed at a position that forms the maximum distance between the spherical seats 8 and 11 of the lower shoe 1 and the upper shoe 2, that is, the lower shoe 1 and the upper shoe 2 are At the same phase, the distance between the centers of the spherical seats 8 and 11 is such that the lower shoe 1 and the upper shoe 2 do not contact each other.
【００１２】 叙上の部材において、下沓１・上沓２・摺動子３は上部構造Ｇの荷重に耐える ものであり、剛体よりなる。 また、図例では、下沓１の球面座８の曲率Ｒと上沓２の球面座１１の曲率ｒと は同一にされているが、格別の差がなければ多少の差は許容されるものである。In the above member, the lower shoe 1, the upper shoe 2, and the slider 3 withstand the load of the superstructure G, and are made of rigid bodies. Further, in the illustrated example, the curvature R of the spherical seat 8 of the lower shoe 1 and the curvature r of the spherical seat 11 of the upper shoe 2 are the same, but some difference is allowed unless there is a particular difference. Is.
【００１３】 このように構成された実施例の軽荷重用免震支持装置Ｓは、次のように作用す る。The seismic isolation support device S for light loads of the embodiment thus configured operates as follows.
【００１４】常時 常時においては、摺動子３はその上下面をそれぞれ上沓２及び下沓１のそれぞ れの球面座８，１１に当接されているので、安定状態を採り、球面座８，１１の 中心に位置する。 上部構造Ｇの荷重は、摺動子３を介して面的に支持されるので、大きな荷重支 持能力を発揮する。 そして、この状態で、上部構造Ｇに多少の力（例えば風荷重）が加わったとし ても安定状態を保持するとともに、かつ、面接触による摩擦抵抗力も付加され、 この支持装置Ｓに起因して上部構造Ｇが揺れることはない。[0014]Always In the normal state, the upper and lower surfaces of the slider 3 are in contact with the spherical seats 8 and 11 of the upper shoe 2 and the lower shoe 1, respectively. Located in the center. Since the load of the superstructure G is supported in a plane through the slider 3, it exerts a large load bearing ability. In this state, even if some force (for example, wind load) is applied to the upper structure G, the stable state is maintained, and the frictional resistance force due to the surface contact is also added. The superstructure G does not shake.
【００１５】地震時 構造系に過大な外力例えば水平地震動が作用したとき、下部構造Ｂの水平振動 に伴い、該下部構造Ｂと上部構造Ｇとの間に相対的変位が惹起され、ひいては下 沓１と上沓２との間の相対的変位となってあらわれる。 摺動子３はこの下沓１と上沓２との間にあって、球面座８，１１に沿って滑り 、この相対的変位に追従することなく、ほぼ定位置で下沓１の変位を上沓２に伝 達させない。[0015]During an earthquake When an excessive external force such as a horizontal seismic motion is applied to the structural system, a relative displacement is caused between the lower structure B and the upper structure G due to the horizontal vibration of the lower structure B, which in turn lowers 1 and 2 It appears as a relative displacement between and. The slider 3 is located between the lower shoe 1 and the upper shoe 2, slides along the spherical seats 8 and 11, and does not follow the relative displacement, and the displacement of the lower shoe 1 is almost fixed at a fixed position. Do not reach 2.
【００１６】 図４〜図６はこの下沓１・上沓２・摺動子３の動きを示す。 すなわち、図４は下部構造Ｂの水平振動の初期状態を示し、下沓１の図上左方 向への変位に伴い、摺動子３はその下面で下沓１の球面座８の曲面に沿って這い 上がる。摺動子３はその移動により傾斜状態となるが、その上面は上沓２の球面 座１１と同一曲率で接しているので、上沓２が傾くことはない。 図５は、下部構造Ｂが最大に揺れた状態を示し、摺動子３は下沓１の球面座８ の右端に寄るとともに、上沓２の球面座１１の左端に寄ることになる。この状態 において、摺動子３の傾斜は大きくなるが、上沓２の球面座１１との曲率効果に より、上沓２はやはり傾くことがない。 下部構造Ｂが復帰方向に振動すると、図４の状態より図６の状態を経過して、 今度は逆の態様となる。 なお、図５は最大振幅の状態を示すものであって、通常はこの状態に至る前に 振動を繰り返すことになる。4 to 6 show the movements of the lower shoe 1, the upper shoe 2, and the slider 3. That is, FIG. 4 shows an initial state of horizontal vibration of the lower structure B. With the displacement of the lower shoe 1 to the left in the figure, the slider 3 is formed on the lower surface of the slider 3 on the curved surface of the spherical seat 8 of the lower shoe 1. Crawl along. Although the slider 3 is inclined due to its movement, the upper surface of the slider 3 is in contact with the spherical seat 11 of the upper shoe 2 with the same curvature, so that the upper shoe 2 does not tilt. FIG. 5 shows a state in which the lower structure B is maximally swayed, and the slider 3 is located near the right end of the spherical seat 8 of the lower shoe 1 and the left end of the spherical seat 11 of the upper shoe 2. In this state, the inclination of the slider 3 becomes large, but the upper shoe 2 never tilts due to the curvature effect of the upper shoe 2 with the spherical seat 11. When the lower structure B vibrates in the returning direction, the state shown in FIG. 6 is passed from the state shown in FIG. It should be noted that FIG. 5 shows the state of maximum amplitude, and usually the vibration is repeated before reaching this state.
【００１７】 このような振動状態にあって、摺動子３は常に安定状態に復帰しようとする特 性が働くとともに、摺動子３の上下面は球面座８，１１に面的に接したものであ るので、その当接面に摩擦抵抗力が生じ、地震動エネルギーを吸収して、振動の 減衰作用を生ずる。 地震動による水平振動はどの方向にも起こり、振動子３はどの方向にも球面座 ８の曲面に沿って這い上がることになり、無方向の水平振動に対応する。In such an oscillating state, the slider 3 has the characteristic of always returning to a stable state, and the upper and lower surfaces of the slider 3 are in surface contact with the spherical seats 8 and 11. Therefore, a frictional resistance force is generated on the abutting surface, absorbs seismic motion energy, and damps vibrations. Horizontal vibration due to seismic motion occurs in any direction, and the oscillator 3 crawls along the curved surface of the spherical seat 8 in any direction, which corresponds to non-directional horizontal vibration.
【００１８】 このように、本実施例の軽荷重用免震装置Ｓによれば、地震動に対し、下部構 造Ｂの変位を上部構造Ｇに伝達させず、上部構造Ｇを常に水平状態に保持すると ともに、荷重支持能力も静止時と全く変わることなく、かつ、復元機能を有する とともに減衰機能も併せ持ち、多機能性を発揮する。As described above, according to the light load seismic isolation device S of the present embodiment, the displacement of the lower structure B is not transmitted to the upper structure G in response to the earthquake motion, and the upper structure G is always kept horizontal. At the same time, the load-carrying capacity does not change at all when stationary, and it has a restoring function and a damping function.
【００１９】 本考案は上記実施例に限定されるものではなく、本考案の基本的技術思想の範 囲内で種々設計変更が可能である。すなわち、以下の態様は本考案の技術的範囲 内に包含されるものである。The present invention is not limited to the above embodiment, and various design changes can be made within the scope of the basic technical idea of the present invention. That is, the following aspects are included within the technical scope of the present invention.
【００２０】 ハ. 考案の効果 本考案の軽荷重用免震支持装置は上記構成よりなり作用を奏するものであるの で、以下の効果を有する。 摺動子は静止時・震動時を通じてその上下面を面的に支持するので、大きな荷 重支持能力を発揮する。 震動状態において、上沓は下沓からの変位を受けず、かつ、水平状態を保持す るので、上部構造に損傷を与えない。 下沓・摺動子・上沓はそれらの互いに接する曲面効果により常に安定状態に復 帰する復元機能を有し、振動の吸収に寄与する。 摺動子の面的接触作用により摩擦抵抗が生じ、静止状態における停止作用があ るばかりでなく、震動状態には減衰効果が生じ、他のダンパー装置を必要としな い。C. Effect of the Invention Since the seismic isolation support device for a light load of the present invention has the above-mentioned configuration and functions, it has the following effects. Since the slider supports the upper and lower surfaces of the slider surface-wise while it is stationary or shaking, it exhibits a large load bearing capacity. In the shaking state, the upper shoe is not displaced from the lower shoe and maintains a horizontal state, so it does not damage the superstructure. The lower shoe, the slider, and the upper shoe have a restoring function that always returns to a stable state due to the curved surface effect in contact with each other, and contributes to the absorption of vibration. The surface contact action of the slider causes frictional resistance, which not only has a stopping action in a stationary state, but also has a damping effect in a vibration state, which does not require any other damper device.
