しかしながら、上記した従来の変位センサーでは、検出器によって最大変位量を検出するため、簡単な目視によって制震ブレースの変形を把握することができないという問題が存在する。また、上記した従来の変位センサーは、高価であって初期の設置費が高く、また維持費も相当かかるため、経済性の観点から十分な数の変位センサーを取り付けることは困難であるという問題が存在する。   However, the above-described conventional displacement sensor has a problem that the deformation of the vibration control brace cannot be grasped by simple visual inspection because the maximum displacement is detected by the detector. Further, the above-described conventional displacement sensors are expensive, have high initial installation costs, and require considerable maintenance costs. Therefore, it is difficult to attach a sufficient number of displacement sensors from the viewpoint of economy. Exists.

本発明は、上記した従来の問題が考慮されたものであり、簡単な目視によって制震ブレースの変形を把握することができるとともに、安価に設置し且つ維持することできる変位センサー、制震ダンパー及び制震構造を提供することを目的としている。   The present invention has been made in consideration of the above-described conventional problems, and it is possible to grasp the deformation of the vibration control brace by simple visual inspection, and to install and maintain the vibration control device at low cost, the vibration control damper, and The purpose is to provide a damping structure.

請求項３記載の発明は、隣り合う柱と、該柱の間に架設されて上下で対向する梁とからなる架構フレームを制震補強する制震構造において、前記架構フレーム内には、斜めに延在する請求項２記載の制震ダンパーが配置されていることを特徴としている。   According to a third aspect of the present invention, there is provided a seismic control structure for controlling and reinforcing a frame composed of adjacent columns and beams that are installed between the columns and are vertically opposed to each other. An extended damping damper according to claim 2 is arranged.

このような特徴により、地震などによって建物の層間変形が生じ、このときの振動エネルギーを内側部が吸収して内側部に変形が生じた場合、これに伴って刃部材は粘弾性体部材を切り裂きつつ移動し、粘弾性体部材には切れ目が形成される。   Due to such features, when an interlayer deformation of a building occurs due to an earthquake, etc., and the vibration energy at this time is absorbed by the inner part and the inner part is deformed, the blade member cuts the viscoelastic body member accordingly. The viscoelastic body member moves while forming a cut.

By doing so, the maximum displacement of the damping damper can be measured. In addition, since this displacement sensor has a simple configuration, it can be installed at a low cost, and when the cut is formed in the viscoelastic body member due to an earthquake or the like, only the viscoelastic body member has to be replaced, so that it is inexpensive. Maintenance can be performed at maintenance costs.

次に、上記した構成からなる変位センサー９、制震ダンパー４及び制震構造の施工方法について説明する。   Next, the construction method of the displacement sensor 9, the damping damper 4 and the damping structure having the above-described configuration will be described.

まず、図２、図３、図４に示すように、予め変位センサー９を制震ダンパー４に取り付ける工程を行う。制震ダンパー４の中間部のカバープレート１１に制震ダンパー４の軸方向に延在する長孔１７をあけ、第２の芯部材１５の側面を露出させる。そして、長孔１７に対向して露出する第２の芯部材１５側面の中央部に両刃の刃部材１９を接合して立設する。刃部材１９は両方の刃１９ａを制震ダンパー４の軸方向にそれぞれ向けて配置し、刃部材１９の上端部は長孔１７から外側に突出させる。次に、長孔１７に粘弾性体部材１８を被せて、枠２１の内側に形成されたセンサー粘弾性体２２に刃部材１９を貫通させ、枠２１の四隅をカバープレート１１にネジ２０で固定する。このとき、センサー粘弾性体２２の中央部に刃部材１９を貫通させるための孔や切れ目を予め形成しておき、この切れ目に刃部材１９を挿通させる。   First, as shown in FIGS. 2, 3, and 4, a process of attaching the displacement sensor 9 to the vibration control damper 4 in advance is performed. A long hole 17 extending in the axial direction of the damping damper 4 is formed in the cover plate 11 in the middle of the damping damper 4 to expose the side surface of the second core member 15. A double-edged blade member 19 is joined and erected at the center of the side surface of the second core member 15 exposed to face the long hole 17. The blade member 19 has both blades 19a arranged in the axial direction of the damping damper 4 and the upper end of the blade member 19 protrudes outward from the long hole 17. Next, the viscoelastic body member 18 is covered with the elongated hole 17, the blade member 19 is passed through the sensor viscoelastic body 22 formed inside the frame 21, and the four corners of the frame 21 are fixed to the cover plate 11 with screws 20. To do. At this time, a hole or a cut for penetrating the blade member 19 is formed in the center of the sensor viscoelastic body 22 in advance, and the blade member 19 is inserted into the cut.

次に、図１に示すように、制震ダンパー４を架構フレーム３内に設置する工程を行う。このとき、予め架構フレーム３の上枠を形成する梁２の中央部に、第１のガセットプレート５を垂設させるとともに、架構フレーム３の下枠を形成する梁２の両端部と柱１との入隅に第２のガセットプレート６を設けておく。そして、上方中央の第１のガセットプレート５と下方両側の第２のガセットプレート６との間に制震ダンパー４をそれぞれ配置する。そして、制震ダンパー４の上端である第１の芯部材１４の上端を高力ボルトによって第１のガセットプレート５に摩擦接合するとともに、制震ダンパー４の下端である第２の芯部材１５の下端を高力ボルトによって第２のガセットプレート６に摩擦接合する。   Next, as shown in FIG. 1, a step of installing the damping damper 4 in the frame 3 is performed. At this time, the first gusset plate 5 is suspended from the central portion of the beam 2 that forms the upper frame of the frame 3 in advance, and both ends of the beam 2 and the columns 1 that form the lower frame of the frame 3 A second gusset plate 6 is provided in the corner of the. And the damping damper 4 is each arrange | positioned between the 1st gusset plate 5 of an upper center, and the 2nd gusset plate 6 of the downward both sides. The upper end of the first core member 14 that is the upper end of the vibration damper 4 is frictionally joined to the first gusset plate 5 with a high-strength bolt, and the second core member 15 that is the lower end of the vibration damper 4 is The lower end is frictionally joined to the second gusset plate 6 with a high-strength bolt.

上記した構成からなる変位センサー９、制震ダンパー４及び制震構造によれば、変位センサー９には、外側部７に取り付けられた粘弾性体部材１８と、制震ダンパー４の軸方向に向けて内側部８に固定され粘弾性体部材１８のセンサー粘弾性体２２を貫通する両刃の刃部材１９とが備えられているため、内側部８が変形した場合、第１の芯部材１４と第２の芯部材１５との間に介在されたダンパー粘弾性体１６が粘性抵抗によって振動エネルギーを吸収し、刃部材１９はセンサー粘弾性体２２を切り裂きつつ移動し、センサー粘弾性体２２には切れ目が形成される。この切れ目の長さを目視により確認することで、制震ダンパー４の最大変位量を測定することができる。   According to the displacement sensor 9, the damping damper 4 and the damping structure having the above-described configuration, the displacement sensor 9 has a viscoelastic body member 18 attached to the outer portion 7 and the axial direction of the damping damper 4. And a double-edged blade member 19 that passes through the sensor viscoelastic body 22 of the viscoelastic body member 18 and is fixed to the inner portion 8, so that when the inner portion 8 is deformed, the first core member 14 and the first core member 14 The damper viscoelastic body 16 interposed between the two core members 15 absorbs vibration energy by viscous resistance, the blade member 19 moves while tearing the sensor viscoelastic body 22, and the sensor viscoelastic body 22 has a break. Is formed. The maximum amount of displacement of the damping damper 4 can be measured by visually confirming the length of the cut.

また、この変位センサー９は簡単な構成からなるため、安価に設置することができるとともに、地震などによりセンサー粘弾性体２２に切れ目が形成された場合に粘弾性体部材１８だけ取り替えればよいため、安価な維持費でメンテナンスすることができる。   Further, since the displacement sensor 9 has a simple configuration, it can be installed at a low cost and only the viscoelastic member 18 needs to be replaced when a break is formed in the sensor viscoelastic body 22 due to an earthquake or the like. It can be maintained at low maintenance costs.

また、センサー粘弾性体２２はダンパー粘弾性体１６と同じ材質の粘弾性体から形成されているため、火災などによって制震ダンパー４が高温状態に晒された場合に、ダンパー粘弾性体１６が溶け出しや物性変化などの損傷が生じるときには、同じようにセンサー粘弾性体２２も損傷する。これによって、熱によるセンサー粘弾性体２２の溶け出しや物性の変化などの損傷具合を確認することで、外側部７に囲まれ外部から確認することができないダンパー粘弾性体１６の損傷具合を目視により確認することができ、サーマルセンサの機能を併せ持つ変位センサー９を提供することができる。   Further, since the sensor viscoelastic body 22 is formed of a viscoelastic body made of the same material as the damper viscoelastic body 16, when the vibration damper 4 is exposed to a high temperature state due to a fire or the like, the damper viscoelastic body 16 is When damage such as melting or physical property change occurs, the sensor viscoelastic body 22 is similarly damaged. Accordingly, the damage state of the damper viscoelastic body 16 that is surrounded by the outer portion 7 and cannot be confirmed from the outside is visually checked by confirming the damage state such as the melting of the sensor viscoelastic body 22 due to heat and the change in physical properties. Thus, it is possible to provide a displacement sensor 9 having both functions of a thermal sensor.

The rib plates 108 extending in the axial direction are welded to each other.

また、一方の溝形鋼１０４のウェブ１０４ｂには、内側部１０２の変位を測定する変位センサー１０９が取り付けられている。変位センサー１０９は、外側部１０１に取り付けられた板状の粘弾性体部材１１０と、内側部１０２に立設された両刃の刃部材１１１とから構成されている。粘弾性体部材１１０は、一方の溝形鋼１０４のウェブ１０４ｂに形成された長孔１１２の外側に配置されており、長孔１１２は粘弾性体部材１１０で塞がれている。粘弾性体部材１１０は、カバープレート１０５にネジ固定される枠１１３と、枠１１３の内側に形成されているセンサー粘弾性体１１４とから構成されている。刃部材１１１はセンサー粘弾性体１１４の中央部を貫通し、刃部材１１１の上端部はセンサー粘弾性体１１４から突出されている。   Further, a displacement sensor 109 that measures the displacement of the inner portion 102 is attached to the web 104 b of one channel steel 104. The displacement sensor 109 is composed of a plate-like viscoelastic body member 110 attached to the outer side portion 101 and a double-edged blade member 111 standing on the inner side portion 102. The viscoelastic body member 110 is disposed outside a long hole 112 formed in the web 104 b of one channel steel 104, and the long hole 112 is closed by the viscoelastic body member 110. The viscoelastic body member 110 includes a frame 113 that is screwed to the cover plate 105 and a sensor viscoelastic body 114 that is formed inside the frame 113. The blade member 111 passes through the center portion of the sensor viscoelastic body 114, and the upper end portion of the blade member 111 protrudes from the sensor viscoelastic body 114.

上記した構成からなる変位センサー１０９、制震ダンパー１００及び制震構造によれば、低降伏点鋼の内側部１０２が変形した場合、振動エネルギーが吸収され、これに伴って刃部材１１１はセンサー粘弾性体１１４を切り裂きつつ移動し、センサー粘弾性体１１４には切れ目が形成される。この切れ目の長さを目視により確認することで、制震ダンパー１００の最大変位量を測定することができる。   According to the displacement sensor 109, the damping damper 100, and the damping structure having the above-described configuration, when the inner portion 102 of the low yield point steel is deformed, the vibration energy is absorbed, and accordingly, the blade member 111 is moved to the sensor viscosity. The elastic body 114 moves while being cut, and a cut is formed in the sensor viscoelastic body 114. The maximum amount of displacement of the vibration damper 100 can be measured by visually checking the length of the cut.

以上、本発明に係る変位センサー９、１０９、制震ダンパー４、１００及び制震構造の第１、第２の実施の形態について説明したが、本発明は上記した第１、第２の実施の形態に限定されるものではなく、その趣旨を逸脱しない範囲で適宜変更可能である。例えば、上記した第１の実施の形態では、変位センサー９をカバープレート１１に設けており、第２の芯部材１５の側面に刃部材１９を固定しているが、本発明は、刃部材１９を第１の芯部材１４の側面に固定してもよく、また、粘弾性系の制震ダンパー４の場合でも第２の実施の形態と同様に変位センサー９を溝形鋼１０のウェブに設けて、刃部材１９を溝形鋼１０のウェブに対向する面に固定してもよく、さらに、鋼材系の制震ダンパー１００の場合でも第１の実施の形態と同様に変位センサー９をカバープレート１１に設けてもよい。   The first and second embodiments of the displacement sensors 9 and 109, the damping dampers 4 and 100, and the damping structure according to the present invention have been described above.

Then, the blade member 19 may be fixed to the surface of the grooved steel 10 facing the web, and even in the case of the steel-based damping damper 100, the displacement sensor 9 is attached to the cover plate as in the first embodiment. 11 may be provided.

また、上記した第１の実施の形態では、センサー粘弾性体２２はダンパー粘弾性体１６と同じ材質の粘弾性体から形成されているが、本発明は、センサー粘弾性体２２をダンパー粘弾性体１６が損傷する温度以下の温度で損傷する性質の粘弾性体から形成してもよい。これによって、ダンパー粘弾性体１６が損傷する前に温度を検知することができ、制震ダンパー４に与える悪影響を抑止することができる。また、上記した第１、第２の実施の形態では、センサー粘弾性体２２、１１４は１種類の粘弾性体から形成されているが、温度特性が異なる複数種類の粘弾性体を組み合わせて形成してもよい。これによって、制震ダンパー４、１００の周りの温度を段階的に把握することができる。   In the first embodiment described above, the sensor viscoelastic body 22 is formed of a viscoelastic body made of the same material as that of the damper viscoelastic body 16, but in the present invention, the sensor viscoelastic body 22 is made of the damper viscoelastic body. You may form from the viscoelastic body of the property damaged at the temperature below the temperature which the body 16 damages. As a result, the temperature can be detected before the damper viscoelastic body 16 is damaged, and adverse effects on the damping damper 4 can be suppressed. In the first and second embodiments described above, the sensor viscoelastic bodies 22 and 114 are formed from one type of viscoelastic body, but are formed by combining a plurality of types of viscoelastic bodies having different temperature characteristics. May be. Thereby, the temperature around the vibration dampers 4 and 100 can be grasped step by step.

また、上記した第１、第２の実施の形態では、枠２１、１１３はネジ固定されているが、本発明は、溶接によって固定してもよく、接着剤を介在して接着してもよく、そのほか嵌め込み式に取り付けてもよい。また、上記した第１の実施の形態では、センサー粘弾性体２２は長さ１５０ｍｍ〜２００ｍｍ、幅３０ｍｍ〜４０ｍｍ、厚さ５ｍｍ〜１０ｍｍ程度に形成されているが、本発明は、予想される最大変位量に応じてセンサー粘弾性体２２の長さを適宜変更してもよく、内側部が変形した際のセンサー粘弾性体２２に形成される切れ目の制震ダンパー４の軸方向に対するずれや刃部材１９の太さ等を考慮してセンサー粘弾性体２２の幅を変更してもよく、耐久性を考慮してセンサー粘弾性体２２の厚さを変更しても良い。   In the first and second embodiments described above, the frames 21 and 113 are fixed with screws. However, the present invention may be fixed by welding or may be bonded with an adhesive. In addition, it may be attached in a fitting type. In the first embodiment described above, the sensor viscoelastic body 22 is formed to have a length of 150 mm to 200 mm, a width of 30 mm to 40 mm, and a thickness of about 5 mm to 10 mm. The length of the sensor viscoelastic body 22 may be changed as appropriate according to the amount of displacement, and the deviation or blade of the break damping damper 4 in the axial direction formed in the sensor viscoelastic body 22 when the inner part is deformed or the blade. The width of the sensor viscoelastic body 22 may be changed in consideration of the thickness of the member 19, and the thickness of the sensor viscoelastic body 22 may be changed in consideration of durability.
