Description

本発明は、建物の非構造壁と梁や柱との境界部の構造スリットに設けられて地震時に制震機能を発揮する制震スリット構造に関するものである。   The present invention relates to a vibration control slit structure that is provided in a structural slit at the boundary between a non-structural wall of a building and a beam or a column and that exhibits a vibration control function in the event of an earthquake.

近年、鉄筋コンクリート造の建物において、剛性バランスを整える一方で偏心率を抑えることを目的として、雑壁などの非構造壁と梁や柱との境界部に構造スリットを設けている。この構造スリットにより、地震の揺れによる非構造壁自身のひび割れ等の損傷を低減することができる。   In recent years, in a reinforced concrete building, a structural slit is provided at the boundary between a non-structural wall such as a miscellaneous wall and a beam or a column in order to adjust the rigidity balance and suppress the eccentricity. This structural slit can reduce damages such as cracks in the non-structural wall itself due to earthquake shaking.

ところで、従来の構造スリットには、例えば発泡ウレタン等の材質の緩衝材をスリット材として埋め込み、壁と梁・柱の縁を切る処理が施されてきた（例えば、特許文献１および２参照）。そして、地震時には緩衝材であるスリット材自身が変形することにより、壁と梁・柱とはそれぞれ個別の挙動を示し、お互いに影響を及ぼさないようにしていた。また、地震時に非構造壁が柱梁フレームの面外に変形することを防ぐ目的で、壁と梁・柱とをスリット材を貫通する連結筋によって繋いでいた。   By the way, the conventional structure slit has been subjected to a process of embedding a cushioning material made of urethane foam or the like as a slit material and cutting the edges of the walls, beams and columns (for example, see Patent Documents 1 and 2). In addition, the slit material itself, which is a buffer material, is deformed during an earthquake, so that the walls and beams / columns show individual behaviors so that they do not affect each other. In addition, in order to prevent the non-structural wall from being deformed out of the plane of the column beam frame during an earthquake, the wall and the beam / column were connected by a connecting bar penetrating the slit material.

ところで、上記の従来の構造スリットは、連結筋やスリット材を施工する手間が掛かるだけでなく、地震力に対して抵抗することを前提とするものではないため、結果として建物の主体構造の耐震性を向上させるための物量を増やす一因となっていた。こうしたことから、偏心率を抑える構造スリット本来の機能を確保し、しかも地震に対する制震デバイスとしての機能を有する合理的な構造で、かつ、意匠的な配慮を払う必要がない構造の開発が要望されていた。   By the way, the above-mentioned conventional structural slits are not only required to construct connecting bars and slit materials, but are also not premised on resisting seismic force. It contributed to the increase of the quantity for improving the performance. For this reason, it is desirable to develop a rational structure that has the original function of a structural slit that suppresses the eccentricity, and that also functions as a vibration control device against earthquakes, and that does not require design considerations. It had been.

本発明は、上記に鑑みてなされたものであって、構造スリット本来の機能を確保し、しかも地震に対する制震デバイスとしての機能を有する合理的な構造で、かつ、意匠的な配慮を払う必要がない制震スリット構造を提供することを目的とする。   The present invention has been made in view of the above, and it is necessary to pay a design consideration with a rational structure that secures the original function of the structural slit and has a function as a vibration control device against earthquakes.

And an energy absorbing means for absorbing vibration energy transmitted to the building.

また、本発明の請求項２に係る制震スリット構造は、上述した請求項１において、前記エネルギー吸収手段は、前記スリットを貫通して前記非構造壁と梁または柱とを連結する極低降伏点鋼を有してなることを特徴とする。   Further, the vibration control slit structure according to claim 2 of the present invention is the above-described vibration suppression slit structure according to claim 1, wherein the energy absorbing means penetrates the slit and connects the non-structural wall and the beam or the column. It is characterized by having spot steel.

また、本発明の請求項３に係る制震スリット構造は、上述した請求項１または２において、前記エネルギー吸収手段は、前記スリット内に設けた粘弾性体を有してなることを特徴とする。   The vibration control slit structure according to claim 3 of the present invention is characterized in that in claim 1 or 2, the energy absorbing means has a viscoelastic body provided in the slit. .

本発明によれば、建物の非構造壁と梁または柱との境界部に設けた構造スリットと、前記スリットに設けられ、前記建物に伝わる震動エネルギーを吸収するエネルギー吸収手段とを備えるので、エネルギー吸収手段が地震に対する制震デバイスとして機能する。しかも、このエネルギー吸収手段はスリットに設けられて外部からは見えない。したがって、構造スリット本来の機能を確保し、しかも地震に対する制震デバイスとしての機能を有する合理的な構造で、かつ、意匠的な配慮を払う必要がない制震スリット構造を提供することができるという効果を奏する。   According to the present invention, since it comprises a structural slit provided at the boundary between a non-structural wall of a building and a beam or a column, and an energy absorbing means provided in the slit and absorbing vibration energy transmitted to the building, The absorbing means functions as a vibration control device for earthquakes. Moreover, the energy absorbing means is provided in the slit and cannot be seen from the outside.

Note that the present invention is not limited to the embodiments.

［実施例１］
まず、本発明に係る実施例１の制震スリット構造１０について説明する。
図３に示すように、本発明に係る実施例１の制震スリット構造１０は、鉄筋９が埋設された鉄筋コンクリート（以下、ＲＣという。）造の建物２において、上部梁４と下部梁６の間に設けた雑壁８（非構造壁）の下部梁６との境界部に設けられる。図１に示すように、この実施例１の制震スリット構造１０は、雑壁８と下部梁６の境界部に設けた構造スリット１２と、このスリット１２に設けられ、建物２に伝わる震動エネルギーを吸収するエネルギー吸収手段としてのアンカー筋１４とを備える。 [Example 1]
First, the damping slit structure 10 of Example 1 which concerns on this invention is demonstrated.
As shown in FIG. 3, the damping slit structure 10 according to the first embodiment of the present invention includes an upper beam 4 and a lower beam 6 in a reinforced concrete (hereinafter referred to as RC) building 2 in which a reinforcing bar 9 is embedded. It is provided in the boundary part with the lower beam 6 of the miscellaneous wall 8 (non-structural wall) provided in between. As shown in FIG. 1, the vibration control slit structure 10 of the first embodiment includes a structure slit 12 provided at the boundary between the miscellaneous wall 8 and the lower beam 6, and vibration energy transmitted to the building 2 provided in the slit 12. And an anchor muscle 14 as energy absorbing means for absorbing water.

アンカー筋１４は、スリット１２内の中央側に緩衝材として充填してあるポリエチレンフォーム１６を貫通して雑壁８と下部梁６とを連結する極低降伏点鉄筋（極低降伏点鋼）からなる。このアンカー筋１４には、例えばＪＩＳ Ｋ５２６５のような塗料を１回塗りすることにより、防錆塗装を施してある。   The anchor bars 14 are made of extremely low yield point reinforcing bars (ultra low yield point steels) that penetrate the polyethylene foam 16 filled as a buffer material on the center side in the slit 12 and connect the miscellaneous wall 8 and the lower beam 6. Become. For example, JIS K5265 is applied to the anchor bar 14 once to provide a rust-proof coating.

スリット１２内の室内Ａ側にはロックウール１８が充填してある。また、スリット１２の壁厚方向最奥側には、室外Ｂ側の凹部２２と連通して雑壁８と下部梁６とを縁切りする数ｍｍ程度の小さな隙間２４が形成してあり、この隙間２４に、塩ビ見切材２６と、室外Ｂ側からの雨水の浸入を防止する水膨張止水材２８とが積層充填してある。さらに、室外Ｂ側の凹部２２には、バックアップ材３０とシール材３２とが介装してある。   Rock wool 18 is filled on the room A side in the slit 12. Further, on the innermost side in the wall thickness direction of the slit 12, there is formed a small gap 24 of about several millimeters communicating with the concave portion 22 on the outdoor B side and cutting the miscellaneous wall 8 and the lower beam 6. 24 is laminated and filled with a PVC parting material 26 and a water expansion waterproofing material 28 for preventing rainwater from entering the outdoor B side. Further, a backup material 30 and a sealing material 32 are interposed in the concave portion 22 on the outdoor B side.

上記実施例１の構成の動作および作用について説明する。
地震発生時に建物２に震動力が作用すると、雑壁８と下部梁６はスリット１２部分を境界として相対的に水平変位する。この水平変位に伴い、双方を繋ぐアンカー筋１４に水平方向の震動力が作用する。このアンカー筋１４は、降伏点が極めて低い極低降伏点鉄筋からなり、わずかな変形で降伏し、かつ、普通鉄筋の２倍程度の変形能力を持つことから、小さな震動から大きな震動まで広範囲の震動エネルギーを吸収することが可能である。このため、震動力でアンカー筋１４が変形することで、建物２に伝わった震動エネルギーの一部を吸収することができる。 The operation and action of the configuration of the first embodiment will be described.
When seismic force acts on the building 2 when an earthquake occurs, the miscellaneous wall 8 and the lower beam 6 are relatively horizontally displaced with the slit 12 as a boundary. Along with this horizontal displacement, a horizontal seismic force acts on the anchor muscle 14 connecting both. This anchor bar 14 consists of a very low yield point rebar with a very low yield point, yields with a slight deformation, and has a deformability about twice that of a normal rebar, so it can be used in a wide range from small to large vibrations. It is possible to absorb vibration energy. For this reason, a part of the seismic energy transmitted to the building 2 can be absorbed by the anchor muscles 14 being deformed by the seismic power.

このように、本発明の制震スリット構造１０は、水平変位の生じる構造スリット１２部分に極低降伏点鉄筋からなるアンカー筋１４を組み込むことにより、地震に対する制震デバイスとしての機能を発揮させ、震動エネルギーの吸収を企図するものである。こうすることで、建物２の地震時の応答値が抑えられ、建物２の主体構造の物量を減らすことが可能となり、コスト削減を図ることができる。   Thus, the vibration control slit structure 10 of the present invention exhibits the function as a vibration control device for earthquakes by incorporating the anchor bars 14 made of extremely low yield point reinforcing bars into the structural slits 12 where horizontal displacement occurs, It is intended to absorb vibration energy. By doing so, the response value at the time of the earthquake of the building 2 can be suppressed, the amount of the main structure of the building 2 can be reduced, and the cost can be reduced.

また、アンカー筋１４はスリット１２に設けられて外部からは見えない。したがって、構造スリット本来の機能を確保し、しかも地震に対する制震デバイスとしての機能を有する合理的な構造で、かつ、意匠的な配慮を払う必要がない制震スリット構造を提供することができる。   The anchor muscle 14 is provided in the slit 12 and cannot be seen from the outside. Therefore, it is possible to provide a seismic control slit structure that secures the original function of the structural slit and has a rational structure having a function as a seismic control device against an earthquake, and that does not require design consideration.

［実施例２］
次に、本発明に係る実施例２の制震スリット構造２０について説明する。
図３に示すように、この実施例２の制震スリット構造２０は、雑壁８と下部梁６の境界部に設けた構造スリット１２と、このスリット１２内の中央側に設けられ、建物２に伝わる震動エネルギーを吸収するエネルギー吸収手段としての粘弾性体３４とを備える。粘弾性体３４は、雑壁８の下面と下部梁６の上面とにそれぞれ当接する状態で設けてある。 [Example 2]
Next, the damping slit structure 20 of Example 2 which concerns on this invention is demonstrated.
As shown in FIG. 3, the damping slit structure 20 of the second embodiment is provided with a structural slit 12 provided at the boundary between the miscellaneous wall 8 and the lower beam 6, and a central side in the slit 12. And viscoelastic body 34 as an energy absorbing means for absorbing the vibration energy transmitted to. The viscoelastic body 34 is provided in contact with the lower surface of the miscellaneous wall 8 and the upper surface of the lower beam 6.

スリット１２内の室内Ａ側にはロックウール１８が充填してある。また、スリット１２の壁厚方向最奥側には、室外Ｂ側の凹部２２と連通して雑壁８と下部梁６とを縁切りする数ｍｍ程度の小さな隙間２４が形成してあり、この隙間２４に、塩ビ見切材２６と、室外Ｂ側からの雨水の浸入を防止する水膨張止水材２８とが積層充填してある。さらに、室外Ｂ側の凹部２２には、バックアップ材３０とシール材３２とが介装してある。   Rock wool 18 is filled on the room A side in the slit 12. Further, on the innermost side in the wall thickness direction of the slit 12, there is formed a small gap 24 of about several millimeters communicating with the concave portion 22 on the outdoor B side and cutting the miscellaneous wall 8 and the lower beam 6. 24 is laminated and filled with a PVC parting material 26 and a water expansion waterproofing material 28 for preventing rainwater from entering the outdoor B side. Further, a backup material 30 and a sealing material 32 are interposed in the concave portion 22 on the outdoor B side.

上記実施例２の構成の動作および作用について説明する。
地震発生時に建物２に震動力が作用すると、雑壁８と下部梁６はスリット１２部分を境界として相対的に水平変位する。この水平変位に伴い、雑壁８と下部梁６との間に設けた粘弾性体３４に水平方向の震動力が作用する。この震動力で粘弾性体３４がせん断変形することで、建物２に伝わった震動エネルギーの一部を吸収することができる。 The operation and action of the configuration of the second embodiment will be described.
When seismic force acts on the building 2 when an earthquake occurs, the miscellaneous wall 8 and the lower beam 6 are relatively horizontally displaced with the slit 12 as a boundary. With this horizontal displacement, horizontal seismic force acts on the viscoelastic body 34 provided between the miscellaneous wall 8 and the lower beam 6. A part of the seismic energy transmitted to the building 2 can be absorbed by the viscoelastic body 34 being shear-deformed by this seismic power.

このように、本発明の制震スリット構造２０は、水平変位の生じる構造スリット１２部分に粘弾性体３４を組み込むことにより、地震に対する制震デバイスとしての機能を発揮させ、震動エネルギーの吸収を企図するものである。こうすることで、建物２の地震時の応答値が抑えられ、建物２の主体構造の物量を減らすことが可能となり、コスト削減を図ることができる。   Thus, the vibration control slit structure 20 of the present invention is intended to absorb the vibration energy by exerting a function as a vibration control device against an earthquake by incorporating the viscoelastic body 34 into the structure slit 12 where the horizontal displacement occurs. To do. By doing so, the response value at the time of the earthquake of the building 2 can be suppressed, the amount of the main structure of the building 2 can be reduced, and the cost can be reduced.

また、粘弾性体３４はスリット１２内に設けられて外部からは見えない。したがって、構造スリット本来の機能を確保し、しかも地震に対する制震デバイスとしての機能を有する合理的な構造で、かつ、意匠的な配慮を払う必要がない制震スリット構造を提供することができる。   The viscoelastic body 34 is provided in the slit 12 and is not visible from the outside. Therefore, it is possible to provide a seismic control slit structure that secures the original function of the structural slit and has a rational structure having a function as a seismic control device against an earthquake, and that does not require design consideration.

なお、上記の実施の形態において、実施例１のアンカー筋１４と実施例２の粘弾性体３４とを併用する構成とすることもできる。この場合、スリット１２内部に設けた粘弾性体３４をアンカー筋１４が上下に貫通する構成としてもよいし、雑壁８の幅方向（図中、紙面に垂直な方向）に異なる位置に粘弾性体３４とアンカー筋１４とを別個に配置してもよい。   In addition, in said embodiment, it can also be set as the structure which uses together the anchor muscle 14 of Example 1, and the viscoelastic body 34 of Example 2. FIG. In this case, it is good also as a structure which the anchor muscle 14 penetrates the viscoelastic body 34 provided in the inside of the slit 12 up and down, or viscoelasticity in the position which differs in the width direction (direction perpendicular to the paper surface in the figure) of the miscellaneous wall 8. The body 34 and the anchor muscle 14 may be arranged separately.

また、上記の実施の形態において、本発明を雑壁８と下部梁６との境界部に設けた構造スリット１２に適用する場合について説明したが、雑壁８の左右の柱との境界部の構造スリットに適用しても本発明と同一の作用効果を奏することができる。   In the above embodiment, the case where the present invention is applied to the structural slit 12 provided at the boundary between the miscellaneous wall 8 and the lower beam 6 has been described. Even when applied to the structure slit, the same effect as the present invention can be obtained.

以上説明したように、本発明によれば、建物の非構造壁と梁または柱との境界部に設けた構造スリットと、前記スリットに設けられ、前記建物に伝わる震動エネルギーを吸収するエネルギー吸収手段とを備えるので、エネルギー吸収手段が地震に対する制震デバイスとして機能する。しかも、このエネルギー吸収手段はスリットに設けられて外部からは見えない。したがって、構造スリット本来の機能を確保し、しかも地震に対する制震デバイスとしての機能を有する合理的な構造で、かつ、意匠的な配慮を払う必要がない制震スリット構造を提供することができる。   As described above, according to the present invention, the structural slit provided at the boundary between the non-structural wall of the building and the beam or column, and the energy absorbing means provided in the slit and absorbing the vibration energy transmitted to the building. Therefore, the energy absorbing means functions as a seismic control device for earthquakes. Moreover, the energy absorbing means is provided in the slit and cannot be seen from the outside. Therefore, it is possible to provide a seismic control slit structure that secures the original function of the structural slit and has a rational structure having a function as a seismic control device against an earthquake, and that does not require design consideration.

以上のように、本発明に係る制震スリット構造は、ＲＣ造の建物に設けられる構造スリットに有用であり、特に、地震時の応答値を低減し、建物の物量を減らしてコスト削減につなげるのに適している。   As described above, the damping slit structure according to the present invention is useful for a structural slit provided in an RC building, and particularly reduces the response value at the time of an earthquake, thereby reducing the amount of the building and reducing the cost.
