Description

本発明は、受け部と、該受け部上を滑動する動部とを有する免震装置及びそれを備えて下部構造体を鉄筋コンクリート造とし、上部構造体を建物とし、前記下部構造体に免震装置の受け部を固定すると共に、前記上部構造体に前記免震装置の動部を固定した免震住宅に関するものである。   The present invention provides a seismic isolation device having a receiving part and a moving part that slides on the receiving part, and the lower structure is made of reinforced concrete, the upper structure is a building, and the lower structure is seismically isolated. The present invention relates to a base-isolated house in which a receiving portion of the device is fixed and a moving portion of the base isolation device is fixed to the upper structure.

免震構造は免震装置がある層の相関変位を大きくすることで、地震の揺れを建物に伝え難くする構造である。ビル等の免震構造は敷地の制約が小さいため大きいレベルの地震を想定しても免震層の変形を大きくすることで設計が可能である。一方、住宅の場合は敷地の制約条件から変形制限がビルに比べて厳しいことが多い。また、建物が軽いことから暴風時による移動が生じる可能性がある。そのため住宅の場合、変形制限装置の設置は必要となる。そこで衝撃の極力少ない変形制限装置が必要となってくる。   The seismic isolation structure increases the relative displacement of the layer where the seismic isolation device is located, making it difficult to transmit the shaking of the earthquake to the building. The seismic isolation structure such as a building can be designed by increasing the deformation of the seismic isolation layer even if a large level of earthquake is assumed because the site constraints are small. On the other hand, in the case of a house, deformation restrictions are often stricter than buildings due to site constraints. In addition, because the building is light, there is a possibility of movement due to storms. Therefore, in the case of a house, installation of a deformation limiting device is necessary. Therefore, a deformation limiting device with as little impact as possible is required.

例えば、特開平１１−００２０４６号公報（特許文献１）には、免震構造の浮き上がり防止装置として、上部構造体が下部構造体から浮き上がることを防止して、積層ゴムに引張り力がかからないようにする免震構造の浮き上がり防止装置が提案されている。   For example, in Japanese Patent Laid-Open No. 11-002046 (Patent Document 1), as an anti-lifting device for a seismic isolation structure, the upper structure is prevented from being lifted from the lower structure so that a tensile force is not applied to the laminated rubber. An anti-lifting device with a seismic isolation structure has been proposed.

特開平１１−００２０４６号公報JP-A-11-002046

しかしながら、前述の特許文献１の技術では、積層ゴムに引き抜きが発生しない付属装置であるため免震装置の設置場所とは別の場所に設置が必要となり敷地の制約が小さいビル等では支障がないが、敷地の制約条件が厳しい都市型住宅の場合は適用が困難となる場合がある。   However, in the technique of the above-mentioned Patent Document 1, since it is an attached device that does not cause the laminated rubber to be pulled out, it is necessary to install it in a place different from the place where the seismic isolation device is installed, and there is no problem in a building or the like with small site restrictions. However, it may be difficult to apply in the case of urban housing with severe site constraints.

また、住宅において、変形制限装置を免震装置とは別に設置しようとすると床下の設置スペースが限定されるため、コンパクトにする必要があり、変形制限装置に動部が衝突した場合の衝撃も極力小さく抑えた上で、浮上りを防止する必要がある。   In addition, if the deformation limiting device is installed separately from the seismic isolation device in a house, the installation space under the floor is limited, so it is necessary to make it compact, and the impact when a moving part collides with the deformation limiting device is as much as possible. It is necessary to prevent the lift while keeping it small.

本発明は前記課題を解決するものであり、その目的とするところは、敷地の制約条件が厳しい都市型住宅の場合であっても過大変形時の衝撃を小さくするとともに、上部構造が下部構造から浮き上がることを防止する機能の適用が容易な免震装置及びそれを備えた免震住宅を提供せんとするものである。   The present invention solves the above-mentioned problems, and the object of the present invention is to reduce the impact at the time of excessive deformation even in the case of urban housing with severe site constraints, and the upper structure from the lower structure. The purpose of the present invention is to provide a seismic isolation device that can easily be applied with the function of preventing it from floating and a seismic isolation housing equipped with the same.

前記目的を達成するための本発明に係る免震装置は、受け部と、該受け部上を滑動する動部とを有する免震装置において、前記動部の水平周囲に環状の突部を設け、前記受け部の外周に立ち上がり壁を設け、前記動部の突部に対応する前記立ち上がり壁に緩衝材を設け、前記動部が前記受け部上を水平移動して前記動部の突部が前記緩衝材に接したのち該緩衝材を凹ませた時、前記環状の突部を係止して前記動部が上方に浮き上がることを阻止する水平突出部を前記立ち上がり壁に設けたことを特徴とする。   To achieve the above object, a seismic isolation device according to the present invention includes a receiving part and a moving part that slides on the receiving part, and an annular protrusion is provided around the horizontal part of the moving part. A rising wall is provided on the outer periphery of the receiving portion, a cushioning material is provided on the rising wall corresponding to the protruding portion of the moving portion, and the moving portion horizontally moves on the receiving portion so that the protruding portion of the moving portion is The rising wall is provided with a horizontal protruding portion that locks the annular protrusion and prevents the moving portion from floating upward when the cushioning material is recessed after contacting the cushioning material. And

また、本発明に係る免震住宅は、前記免震装置が、鉄筋コンクリート造からなる下部構造体と、建物である上部構造体との間に設けられ、前記下部構造体に前記免震装置の受け部を固定すると共に、前記上部構造体に前記免震装置の動部を固定したことを特徴とする。   Further, the seismic isolation house according to the present invention is such that the seismic isolation device is provided between a lower structure made of reinforced concrete and an upper structure that is a building, and the lower structure receives the seismic isolation device. And a moving part of the seismic isolation device is fixed to the upper structure.

本発明に係る免震装置によれば、免震装置の受け部の外周に立ち上がり壁を設け、該免震装置の動部の突部に対応する該立ち上がり壁に緩衝材を設け、動部の水平周囲に設けた環状の突部を係止して該動部が上方に浮き上がることを阻止する水平突出部を該立ち上がり壁に備えているため、水平方向の震動により動部の水平周囲に設けた環状の突部が緩衝材に当り、衝突時の衝撃を緩和させ、その後、動部が上方に浮き上がろうとした場合に動部の水平周囲に設けた環状の突部が立ち上がり壁の水平突出部に衝突して係止され過大変形時の衝撃が緩和され、浮き上がりの抑制にもつながる。   According to the seismic isolation device of the present invention, a rising wall is provided on the outer periphery of the receiving portion of the seismic isolation device, a buffer material is provided on the rising wall corresponding to the protrusion of the moving portion of the seismic isolation device, Since the rising wall is provided with a horizontal protrusion that locks the ring-shaped protrusion provided around the horizontal and prevents the moving part from floating upward, it is provided around the horizontal of the moving part by horizontal vibration. The ring-shaped protrusion provided around the horizontal part of the moving part rises to the horizontal of the rising wall when the ring-shaped protruding part hits the cushioning material and alleviates the impact at the time of the collision. It collides with the protrusion and is locked, and the impact at the time of excessive deformation is mitigated, leading to suppression of lifting.

立ち上がり壁に設ける緩衝材としては、発砲スチロール製の捨て型枠とすることで施工が容易に出来る。   As the cushioning material provided on the rising wall, construction can be facilitated by using a foamed styrene foam frame.

また、本発明に係る免震住宅によれば、上記免震装置を、鉄筋コンクリート造からなる下部構造体と、建物である上部構造体との間に設け、前記下部構造体に前記免震装置の受け部を固定すると共に、前記上部構造体に前記免震装置の動部を固定したことにより、敷地の制約条件が厳しい都市型住宅の場合であっても鉄骨建物からなる上部構造が鉄筋コンクリート造からなる下部構造から浮き上がることを防止する機能の適用が容易な免震装置を備えた免震住宅を提供することが出来る。   Moreover, according to the seismic isolation house according to the present invention, the seismic isolation device is provided between a lower structure made of reinforced concrete and an upper structure that is a building, and the seismic isolation device is installed in the lower structure. While fixing the receiving part and fixing the moving part of the seismic isolation device to the upper structure, the upper structure made of steel building is made of reinforced concrete even in the case of urban housing with severe site constraints It is possible to provide a seismic isolation house equipped with a seismic isolation device that can be easily applied with the function of preventing the substructure from being lifted.

鉄筋コンクリート造からなる下部構造体と鉄骨建物からなる上部構造体との間に免震装置が設けられた住宅において、鉄筋コンクリート造からなる下部構造体が住宅の１階、建物である上部構造体が２階以上にした場合、（１）狭小敷地のとき大地震等に起因して上部構造体は敷地に対して大きく水平移動するが下部構造体は敷地に対して移動しないので、下部構造体と例えば塀など外部設置物と距離が変わることがなく、人が挟まれることがない、（２）１階を鉄筋コンクリートにすることで、免震の必要のない例えばピロティにし車庫や物置などに自由に使えるようにできる。即ち、本当に免震の必要な居住空間である２階以上のみを免震住宅とすることができる。このような構造の住宅は集合住宅として使用するのに適する等の効果がある。   In a house in which a seismic isolation device is provided between a lower structure made of reinforced concrete and an upper structure made of steel frame, the lower structure made of reinforced concrete is the first floor of the house, and the upper structure that is a building is 2 When the floor is higher than the floor, (1) When the site is small, the upper structure moves horizontally relative to the site due to a large earthquake, but the lower structure does not move relative to the site. There is no change in distance from external installations such as fences, and people are not caught. (2) By using reinforced concrete on the first floor, there is no need for seismic isolation, for example, it can be freely used for garages and storages. You can That is, only the second floor or higher, which is a living space that really requires seismic isolation, can be made a seismic isolation house. The housing having such a structure is advantageous in that it is suitable for use as a collective housing.

FIG. 1 is a plan view and a cross-sectional explanatory view showing the structure of a seismic isolation device according to the present invention and a seismic isolation house equipped with the same, and FIG. 2 is provided between an upper part composed of a steel building and a lower part composed of a reinforced concrete structure. FIG. 3 is an explanatory cross-sectional view for explaining the operation of the seismic isolation device according to the present invention.

図１及び図２において、１は鉄筋コンクリート造からなる住宅建物の下部構造体であり、２は鉄骨建物からなる住宅建物の上部構造体である。鉄筋コンクリート造からなる下部構造体１と、鉄骨建物からなる上部構造体２との間には本発明に係る免震装置３が設けられて免震住宅が構成されている。   1 and 2, 1 is a lower structure of a residential building made of reinforced concrete, and 2 is an upper structure of a residential building made of a steel frame building. A seismic isolation device 3 according to the present invention is provided between a lower structure 1 made of reinforced concrete and an upper structure 2 made of a steel building to constitute a seismic isolation house.

鉄筋コンクリート造の下部構造体１には、免震装置３の受け部３ａが固定されている。受け部３ａは表面が平滑で滑り性能を有する鋼板等が適用可能である。また、鉄骨建物からなる上部構造体２の柱（或いは間柱）２ａの下端部には免震装置３の動部３ｂが固定されている。   The receiving part 3a of the seismic isolation device 3 is fixed to the reinforced concrete lower structure 1. A steel plate or the like having a smooth surface and sliding performance can be applied to the receiving portion 3a. Moreover, the moving part 3b of the seismic isolation device 3 is being fixed to the lower end part of the column (or space | interval) 2a of the upper structure 2 which consists of a steel frame building.

動部３ｂの水平周囲には環状の突部３ｃが設けられている。突部３ｃは動部３ｂの外周面よりも外側に突出した構成であれば良く、動部３ｂの支持軸３ｄの外周にリング状の部材を取り付けたものや、動部３ｂの支持軸３ｄの下面に円板状のフランジ部材を取り付けたものを採用することが出来る。   An annular protrusion 3c is provided around the horizontal portion of the moving part 3b. The protrusion 3c may be configured to protrude outward from the outer peripheral surface of the moving part 3b, such as a ring-shaped member attached to the outer periphery of the support shaft 3d of the moving part 3b, or the support shaft 3d of the moving part 3b. One having a disk-like flange member attached to the lower surface can be employed.

免震装置３の受け部３ａの外周には立ち上がり壁３ｅが設けられており、免震装置３の動部３ｂの突部３ｃに対応する立ち上がり壁３ｅに緩衝材３ｆが設けられている。本実施形態の立ち上がり壁３ｅは図２に示すように、受け部３ａの外周に円形状に設けられており、その内周面側にリング状の緩衝材３ｆが設けられている。緩衝材３ｆの上部には水平突出部３ｇが設けられている。本実施形態の緩衝材３ｆは、水平突出部３ｇを成形する際の発砲スチロール製の捨て型枠により構成されている。   A rising wall 3 e is provided on the outer periphery of the receiving portion 3 a of the seismic isolation device 3, and a buffer material 3 f is provided on the rising wall 3 e corresponding to the protrusion 3 c of the moving portion 3 b of the seismic isolation device 3. As shown in FIG. 2, the rising wall 3e of this embodiment is provided in a circular shape on the outer periphery of the receiving portion 3a, and a ring-shaped cushioning material 3f is provided on the inner peripheral surface side thereof. A horizontal protrusion 3g is provided on the top of the cushioning material 3f. The cushioning material 3f of the present embodiment is constituted by a discarded mold frame made of foamed polystyrene when the horizontal protrusion 3g is formed.

このような構成において、水平方向の震動が発生したとき、図３（ａ）に示すように、免震装置３の動部３ｂが受け部３ａ上を水平移動して該動部３ｂの突部３ｃが緩衝材３ｆに接したのち（図３（ｂ）参照）、該緩衝材３ｆを凹ませた時（図３（ｃ）参照）、立ち上がり壁３ｅに設けた水平突出部３ｇにより環状の突部３ｃを係止して該動部３ｂが上方に浮き上がることを阻止することが出来る。   In such a configuration, when a horizontal vibration occurs, as shown in FIG. 3A, the moving part 3b of the seismic isolation device 3 moves horizontally on the receiving part 3a, and the protruding part of the moving part 3b. After 3c comes into contact with the cushioning material 3f (see FIG. 3B), when the cushioning material 3f is recessed (see FIG. 3C), an annular projection is formed by the horizontal projection 3g provided on the rising wall 3e. The portion 3c can be locked to prevent the moving portion 3b from floating upward.

即ち、下部に設けた免震装置３の受け部３ａの外周に立ち上がり壁３ｅを設け、上部に設けた免震装置３の動部３ｂの突部３ｃに対応する該立ち上がり壁３ｅに緩衝材３ｆを設け、該動部３ｂの水平周囲に設けた環状の突部３ｃを係止して該動部３ｂが上方に浮き上がることを阻止する水平突出部３ｇを該立ち上がり壁３ｅに備えているため、水平方向の震動により動部３ｂの水平周囲に設けた環状の突部３ｃが緩衝材３ｆに当り、衝突時の衝撃を緩和させ、その後、動部３ｂが上方に浮き上がろうとした場合に該動部３ｂの水平周囲に設けた環状の突部３ｃが立ち上がり壁３ｅの水平突出部３ｇに衝突して係止され、過大変形時の衝撃が緩和され、浮き上がりの抑制が出来る。   That is, the rising wall 3e is provided on the outer periphery of the receiving portion 3a of the seismic isolation device 3 provided at the lower portion, and the cushioning material 3f is provided on the rising wall 3e corresponding to the protrusion 3c of the moving portion 3b of the seismic isolation device 3 provided at the upper portion. The rising wall 3e is provided with a horizontal protrusion 3g that locks the annular protrusion 3c provided around the horizontal of the moving part 3b and prevents the moving part 3b from floating upward. When the annular protrusion 3c provided around the horizontal portion of the moving part 3b hits the shock absorbing material 3f due to the horizontal vibration, the shock at the time of the collision is reduced, and then the moving part 3b tries to lift upward. An annular projection 3c provided around the horizontal portion of the moving portion 3b collides with and is locked by the horizontal projection 3g of the rising wall 3e, so that an impact at the time of excessive deformation is alleviated and lifting can be suppressed.

立ち上がり壁３ｅに設ける緩衝材３ｆとして、発砲スチロール製の捨て型枠とすることで施工が容易に出来る。   The buffer material 3f provided on the rising wall 3e can be constructed easily by using a discarded mold made of foamed polystyrene.

また、上記免震装置３を、鉄筋コンクリート造からなる下部構造体１と、鉄骨建物からなる上部構造体２との間に設けることにより、敷地の制約条件が厳しい都市型住宅の場合であっても鉄骨建物からなる上部構造体２が鉄筋コンクリート造からなる下部構造体１から浮き上がることを防止する機能の適用が容易な免震装置３を備えた免震住宅を提供することが出来る。   Moreover, even if it is a case of a city-type house where the site restrictions are severe, by providing the seismic isolation device 3 between the lower structure 1 made of reinforced concrete and the upper structure 2 made of a steel building. It is possible to provide a base-isolated house including the base-isolation device 3 that can be easily applied with a function of preventing the upper structure 2 made of a steel building from floating from the lower structure 1 made of reinforced concrete.
