Description
本発明は一般に木造家屋の耐震又は風圧強度測定方法に関するものであり、より特定的には、専門技術を必要とせず、継続的に安価で正確な耐震診断を行なうことができる耐震又は風圧強度測定方法に関する。この発明はまた、そのような測定方法を実現できる木造家屋の耐震又は風圧強度測定装置に関する。 The present invention relates generally to a method for measuring seismic or wind pressure strength of a wooden house, and more specifically, seismic or wind pressure strength measurement that does not require specialized techniques and can be performed continuously at low cost and accurately. Regarding the method. The present invention also relates to a seismic or wind pressure intensity measuring device for a wooden house that can realize such a measuring method.
図９を参照して、例えば地震時の建物は、下の階に対して上の階が水平移動して変形する。この変形（移動）の量を階高で割った値を層間変形角という。例えば、階高３ｍ（ｈ＝３００）で１０ｃｍ横移動(δ＝１０)すれば、θ=１０／３００＝１／３０ ｒａｄ となる。一般の木造住宅は、層間変形角が１／３０ ｒａｄになれば非常に危険である。これは、台風などの風圧による水平荷重がかかる場合にも同様である。 Referring to FIG. 9, for example, a building at the time of an earthquake is deformed by the upper floor moving horizontally relative to the lower floor. A value obtained by dividing the amount of deformation (movement) by the floor height is called an interlayer deformation angle. For example, if the floor is moved 3 cm (h = 300) and moved 10 cm laterally (δ = 10), θ = 10/300 = 1/30 rad. A general wooden house is very dangerous if the interlayer deformation angle becomes 1/30 rad. The same applies to a case where a horizontal load due to wind pressure such as a typhoon is applied.
従来の木造住宅の耐震精密診断は、耐震知識を持つ専門技術者が現地調査を行い、平面計画、地盤、老朽度を考慮し、「木造住宅の耐震精密診断と補強方法」の指標に基く机上検討で、水平耐力を算出し、想定される地震に対する耐震強度を算出するものである。 The conventional seismic precision diagnosis of wooden houses is carried out by a field engineer who has seismic knowledge and considers the floor plan, the ground, and the degree of aging. In the study, the horizontal strength is calculated and the seismic strength against the assumed earthquake is calculated.
特許文献１には、地震時の加速度、構造変位を、加速度センサージャイロによる電子機器を用いて診断する方法が開示されている。この診断方法は、加速度センサーとジャイロセンサーとを備えた地震計を用い、加速度センサーの出力から、建築構造物の並進変位成分を求めると共に、ジャイロセンサーの出力から建築構造物のロッキング成分及び／又はねじれ成分を求め、上記並進変位成分からロッキング成分及び／又はねじれ成分の影響を除去して、上記建築構造物の歪みを評価するものである。 Patent Document 1 discloses a method of diagnosing acceleration and structural displacement during an earthquake using an electronic device using an acceleration sensor gyro. This diagnostic method uses a seismometer equipped with an acceleration sensor and a gyro sensor, obtains a translational displacement component of the building structure from the output of the acceleration sensor, and rocks the building structure and / or from the output of the gyro sensor. The torsional component is obtained, the influence of the rocking component and / or the torsional component is removed from the translational displacement component, and the distortion of the building structure is evaluated.
また、特許文献２は、処理装置と記憶装置を有するコンピュータにより実行される簡易耐震診断処理方法を開示する。これは、処理装置と記憶装置とを有するコンピュータにより実行される簡易耐震診断処理方法であって、前記処理装置により、評価階以上の床面積と壁長とから第１のパラメータを算出し、前記記憶装置に格納する第１パラメータ算出ステップと、前記処理装置により、整形性に関する指標値と辺長比に関する指標値と地下室に関する指標値と平面剛性に関する指標値とから形状指標値を特定し、前記記憶装置に格納する形状指標値特定ステップと、前記処理装置により、前記記憶装置に格納された前記第１のパラメータと、予め定められた少なくとも上限値関数と下限値関数とから、第２のパラメータの上限値及び下限値を算出し、前記記憶装置に格納するステップと、前記処理装置により、経年に関する指標値と前記記憶装置に格納された前記形状指標値及び前記第２のパラメータの上限値及び下限値とから、構造耐震指標の上限値及び下限値を算出し、前記記憶装置に格納する構造耐震指標算出ステップと、を含む簡易耐震診断処理方法を開示する。
しかしながら、以上の従来技術による調査方法では、建物の施工性や積載状態、経年変化による劣化は考慮されず、簡易ではあるが建物使用状況に合致した正確な耐震診断が困難である。 However, the above-described conventional investigation methods do not consider deterioration due to building workability, loading conditions, and secular changes, and it is difficult to make an accurate seismic diagnosis that matches the building usage conditions, although it is simple.
また、電子機器による測定は、装置の取り付け、及び測定による数値の処理に専門的技術を要する。また地震時における電力の供給に対して脆弱であり、さらに設置に係る費用負担が大きい。 In addition, measurement by an electronic device requires specialized technology for device installation and processing of numerical values by measurement. In addition, it is vulnerable to power supply in the event of an earthquake, and the cost of installation is high.
同じくコンピュータを処理装置、記憶装置に利用した診断方法も前記同様高価であり、専門技術を要し且つ容易に確認できない。また電力に備える必要性が求められる。 Similarly, a diagnosis method using a computer as a processing device and a storage device is also expensive as described above, requires specialized techniques, and cannot be easily confirmed. In addition, it is necessary to prepare for electric power.

専門技術を必要とせず、継続的に安価で正確な耐震又は風圧強度に関する診断を行なうことができる耐震又は風圧強度測定方法を提供するという目的を、本発明に係る木造家屋の耐震強度又は風圧強度測定装置を、窓枠の上桟と縦桟の交差点に取付けることによって実現した。以下、この発明の実施の形態を、図を用いて説明する。 For the purpose of providing a seismic or wind pressure strength measuring method capable of making a diagnosis on seismic or wind pressure strength continuously and inexpensively without requiring specialized technology, the seismic strength or wind pressure strength of the wooden house according to the present invention is provided. The measuring device was realized by installing it at the intersection of the upper and vertical bars of the window frame. Embodiments of the present invention will be described below with reference to the drawings.
図１（Ａ）を参照して、建物は鉛直面１，２と水平面３，４，５で構成されている。 Referring to FIG. 1 (A), the building is composed of vertical planes 1 and 2 and horizontal planes 3, 4 and 5.
図１（Ｂ）を参照して、地震又は風圧により、水平方向に荷重が加わったとき（水平荷重時という）、それに伴って、木造家屋の鉛直面１及び鉛直面２が傾く。水平荷重に直交する鉛直面１，２は変形し、家屋に付随する窓６，７も同様の変形が起こる。１階回転角度に対応して窓も図のように変形する。２階回転角度に対応して窓も図のように変形する。本発明では、窓６，７の変形を耐震又は風圧強度測定装置８で測定し、層間変形角を求めるのである。変形は、１階部分と２階部分で、それぞれ異なった値となり、また同一階でも互いに直交するＸ方向、Ｙ方向（後述する）で異なる値となる。併せて測定位置によりＸ方向、Ｙ方向の値も違ってくる。同一階のＸｎ方向、Ｙｎ方向（Ｘｎ：東西南北、北東、北西等種々の方角を意味している）を変えて、層間変形角を求めると、建物の回転ベクトルが得られる。 Referring to FIG. 1B, when a load is applied in the horizontal direction due to an earthquake or wind pressure (referred to as horizontal load), the vertical plane 1 and the vertical plane 2 of the wooden house are inclined accordingly. The vertical planes 1 and 2 orthogonal to the horizontal load are deformed, and the windows 6 and 7 associated with the house are similarly deformed. The window is also deformed as shown in the figure corresponding to the first floor rotation angle. The window is also deformed as shown in the figure corresponding to the second floor rotation angle. In the present invention, the deformation of the windows 6 and 7 is measured by the earthquake resistance or wind pressure intensity measuring device 8 to determine the interlayer deformation angle. The deformation has different values for the first floor portion and the second floor portion, and also has different values in the X direction and Y direction (described later) on the same floor. In addition, the values in the X and Y directions vary depending on the measurement position. By changing the Xn direction and Yn direction on the same floor (Xn: various directions such as east, west, south, north, northeast, and northwest) and determining the interlayer deformation angle, a rotation vector of the building can be obtained.
図１(Ｃ)を参照して、各階の層間変形角と同階のイ、ロ層間変形角の差により、建物の水平回転角が求められる。 With reference to FIG. 1 (C), the horizontal rotation angle of a building is calculated | required by the difference of the interlayer deformation angle of each floor | floor and the b and b interlayer deformation angle of the same floor.
窓６，７は、ガラスをはめ込む枠である上桟と下桟と縦桟を有し、本発明に係る耐震強度又は風圧強度測定装置を取付ける、横架材と鉛直材の例として代表的なものである。 The windows 6 and 7 have an upper frame, a lower beam, and a vertical beam, which are frames into which glass is fitted, and are typical examples of horizontal members and vertical members to which the seismic strength or wind pressure strength measuring device according to the present invention is attached. Is.
図２（Ａ）を参照して、実施の形態に係る耐震又は風圧強度測定装置８（その構成の一例を実施例１で詳述する）は、平常時に、窓枠の上桟２１と縦桟２２に接して取り付けられる。耐震又は風圧強度測定装置８は、横支持部材８ａと縦支持部材８ｂとからなるＬ字状部材を含む。この取り付け操作は簡単であり、既存の建物の測定を容易にし、専門知識を要しない。実施例に係る耐震又は風圧強度測定装置８は、測定ピン２５と表示部３３を備え、水平荷重時に、予め定められた位置、すなわち測定ピン２５の位置において、Ｌ字状部材の横支持部材８ａと上桟２１との離隔の距離の変化を測定する。詳細は後述するが、図２（Ｂ）に示すように、窓枠が地震時Ａ方向に歪むと（回転角Ａ）、Ｌ字状部材の横支持部材８ａと上桟２１との離隔の距離は図のように広がる。一方、図２（Ｃ）に示すように、窓枠が地震時Ｂ方向に歪むと（回転角Ｂ）、測定ピン２５の位置において、Ｌ字状部材の横支持部材８ａと上桟２１との離隔の距離は図のように縮まる。 Referring to FIG. 2 (A), the seismic resistance or wind pressure intensity measuring device 8 (an example of the configuration thereof will be described in detail in Example 1) according to the embodiment, 22 is attached in contact with. The seismic or wind pressure strength measuring device 8 includes an L-shaped member composed of a lateral support member 8a and a longitudinal support member 8b. This installation operation is simple, facilitates the measurement of existing buildings and does not require specialized knowledge. The seismic or wind pressure intensity measuring device 8 according to the embodiment includes a measurement pin 25 and a display unit 33, and at the time of a horizontal load, at a predetermined position, that is, the position of the measurement pin 25, a lateral support member 8a of an L-shaped member. The change in the distance between the upper rail 21 and the upper rail 21 is measured. Although details will be described later, as shown in FIG. 2 (B), when the window frame is distorted in the direction A during the earthquake (rotation angle A), the distance between the L-shaped lateral support member 8a and the upper rail 21 Spreads as shown. On the other hand, as shown in FIG. 2C, when the window frame is distorted in the B direction at the time of the earthquake (rotation angle B), the L-shaped member horizontal support member 8a and the upper rail 21 are located at the position of the measurement pin 25. The distance of the separation is reduced as shown in the figure.
このＬ字状部材の横支持部材と前記横架材との離隔の距離の変化を増幅して角度の変形量に変換し、この角度の変形量の最大を、前記水平荷重時における層間変形角に換算して表示部３３に表示させる。 A change in the distance between the lateral support member of the L-shaped member and the horizontal member is amplified and converted into an angular deformation amount, and the maximum deformation amount of the angle is determined as an interlayer deformation angle during the horizontal load. Is converted and displayed on the display unit 33.
すなわち、図２（Ｂ）に示すように、地震時Ａ方向に回転角Ａで窓枠が傾いた時、針Ａが動いて、変形量が角度の変形量として表示される。針Ａは、動いた位置に留まるように構成されており、変形量を履歴として目視できる。図２（Ｃ）に示すように、地震時Ｂ方向に回転角Ｂで窓枠が傾いた時、針Ｂが動いて、変形量が角度の変形量として表示される。針Ｂは、動いた位置に留まっており、変形量を履歴として目視できる。いずれの場合も、指針は最大変形角を表示し、建物の復元に追随しない。 That is, as shown in FIG. 2B, when the window frame is tilted at the rotation angle A in the A direction at the time of the earthquake, the needle A moves and the deformation amount is displayed as the angular deformation amount. The needle A is configured to remain in the moved position, and the deformation amount can be visually observed as a history. As shown in FIG. 2C, when the window frame is tilted at the rotation angle B in the B direction at the time of the earthquake, the needle B moves and the deformation amount is displayed as the angular deformation amount. The needle B remains in the moved position, and the deformation amount can be visually observed as a history. In either case, the pointer displays the maximum deformation angle and does not follow the restoration of the building.
図３は、表示部３３の正面図である。表示部３３には、指針の位置により層間変形の状態をわかりやすくするために、中央（平常時の針の位置）から時計回りに右方向注意ゾーン、右方向警戒ゾーン、右方向危険ゾーンが順に表示され、中央から反時計回りに左方向注意ゾーン、左方向警戒ゾーン、左方向危険ゾーンが順に表示されている。これらは、建物変位の計算から、層間変形角を求めたものを表示している。図中、１／２４０位置、１／１２０位置は、計算で求めた層間変形角を表している。すなわち、表示部３３では、上記角度の変形量の最大が、水平荷重時における層間変形角に換算して表示される。 FIG. 3 is a front view of the display unit 33. In order to make it easy to understand the state of interlayer deformation depending on the position of the pointer, the display unit 33 includes a right caution zone, a right caution zone, and a right danger zone in order from the center (the position of the needle at normal times) in a clockwise direction. The left caution zone, the left caution zone, and the left danger zone are displayed in order counterclockwise from the center. These display the values obtained for the interlaminar deformation angles from the building displacement calculations. In the figure, the 1/240 position and the 1/120 position represent the interlayer deformation angles obtained by calculation. That is, the display unit 33 displays the maximum deformation amount of the angle in terms of the interlayer deformation angle at the time of horizontal load.
図４を参照して、方角の一をＸ方向として、それに直交する方向をＹ方向としたとき、横架材の延びている方角がＸ方向の場所及び横架材の延びている方角がＹ方向の場所の少なくとも２つの場所において、横架材と鉛直材の交差点付近に、横支持部材と縦支持部材とからなるＬ字状部材を取り付けて、それぞれ、上記測定方法を実行する。これにより、水平変位の大きな部分は、耐震力が小さく補強を必要とすることが容易に診断できる。各測定位置の水平変位の差により建物の回転角を導き出す。これにより、その回転方向に建物が倒壊することが診断できる。複数階を有する家屋では、各階でそれぞれ、上記測定方法を実行する。 Referring to FIG. 4, when one direction is the X direction and the direction orthogonal thereto is the Y direction, the direction in which the horizontal member extends is the X direction and the direction in which the horizontal member extends is Y. At least two locations in the direction, an L-shaped member composed of a lateral support member and a longitudinal support member is attached in the vicinity of the intersection between the horizontal member and the vertical member, and the above measurement method is executed. Thereby, it can be easily diagnosed that a portion having a large horizontal displacement has a small seismic force and requires reinforcement. The rotation angle of the building is derived from the difference in horizontal displacement at each measurement position. Thereby, it can be diagnosed that a building collapses in the rotation direction. In a house having a plurality of floors, the measurement method is executed on each floor.
耐震又は風圧強度測定装置８の取り付けは、横架材と鉛直材であれば、窓枠の上桟と縦桟の組み合わせ以外にも、土台、梁と柱の組み合わせでも可能である。 The seismic resistance or wind pressure strength measuring device 8 can be mounted by a combination of a base, a beam and a column in addition to a combination of an upper frame and a vertical beam of a window frame, as long as it is a horizontal member and a vertical member.
実施の形態に係る耐震又は風圧強度測定装置８の使用方法をさらに詳しく説明する。 The usage method of the earthquake-resistant or wind-pressure-strength measuring apparatus 8 which concerns on embodiment is demonstrated in detail.
図１，２，３を再び参照して、水平荷重時（地震や台風で建物が揺れた時）、まず、装置の表示部３３の表示を確認する。これにより、即時に水平荷重による建物への影響が確認できる。危険ゾーンに針Ａ，針Ｂが止まっていれば、次の水平荷重時に倒壊することの可能性が高く、建物外への非難を検討する。同針が警戒ゾーンや注意ゾーンに停止しても、わずかな水平荷重で針Ａ又はＢが動くならば、建物の耐力が小さく、耐震補強を必要とする。また、後述する図７で説明する針Ｃが中央に復帰しない場合は、水平荷重による影響が弾性変形を超える変形があったことが確認できる。災害後建物使用に関する調査が専門員によって行なわれるが、現地で確認できるのは災害後の層間変形角だけであるが、この装置の表示には災害時の最大層間変形角の記録が残り、より正確な使用測定が容易にできる。 Referring to FIGS. 1, 2 and 3 again, when a horizontal load is applied (when a building is shaken by an earthquake or a typhoon), first, the display on the display unit 33 of the apparatus is confirmed. Thereby, the influence on a building by a horizontal load can be confirmed immediately. If the needle A and needle B are stopped in the danger zone, there is a high possibility of collapsing during the next horizontal load. Even if the needle stops in the warning zone or the caution zone, if the needle A or B moves with a slight horizontal load, the strength of the building is small and seismic reinforcement is required. Moreover, when the needle | hook C demonstrated in FIG. 7 mentioned later does not return to a center, it can confirm that the influence by a horizontal load had the deformation | transformation exceeding elastic deformation. A survey on building use after a disaster is conducted by specialists, but only the interlayer deformation angle after the disaster can be confirmed on site, but the record of the maximum interlayer deformation angle at the time of the disaster remains on the display of this device, and more Accurate use measurement can be easily performed.
上記の測定により耐震補強を行なう場合、各部装置の針を読み取り、建物の脆弱な部分を想定する。大きく針が動いた方向に補強を要するのが安易に理解できる。また、各部の測定の値の比較で、建物の構造的バランスを導くのが容易である。また、目視できない部分の損傷も層間変形角と壁材との関係から容易に想定できる。例えば、モルタル塗りの外壁は層間変形角が１／３０ｒａｄを越えても、表面損傷が見受けられないが、下地は層間変形角が１／１２０ｒａｄを超える変形で、すでに内部は損傷が始まっている。 When earthquake-proof reinforcement is performed by the above measurement, the needle of each part device is read and a weak part of the building is assumed. It can be easily understood that reinforcement is required in the direction in which the needle moved greatly. Moreover, it is easy to derive the structural balance of the building by comparing the measured values of each part. In addition, damage of a portion that cannot be visually observed can be easily assumed from the relationship between the interlayer deformation angle and the wall material. For example, even if the interlayer deformation angle exceeds 1/30 rad on the outer wall of the mortar coating, no surface damage is observed, but the underlying layer is a deformation whose interlayer deformation angle exceeds 1/120 rad, and the inside has already started to be damaged.
階別の層間変形角をもとに、階別の耐震補強が可能であり、的確な補強は工事費の低減につながる。また測定器の取り付け位置が自由なため、建物平面が複雑で水平構造面が複数存在する、又は不確定な建物の正確な耐震診断ができるのも、本耐震又は風圧強度測定装置の特徴である。 Seismic reinforcement for each floor is possible based on the interlayer deformation angles for each floor, and accurate reinforcement leads to a reduction in construction costs. In addition, because the installation position of the measuring instrument is free, it is also a feature of this earthquake resistance or wind pressure intensity measuring device that the building plane is complicated and there are multiple horizontal structure planes, or an accurate earthquake resistance diagnosis of an indeterminate building can be performed. .
なお、図４は、２階建ての建物の例示であるが、平屋建て、３階建て等の複数階を有する建物にも同じく使用することができる。また増築や複雑な平面を有する（例凹型）の構造的に一体と扱えない建物の測定も可能である。測定装置は横架材と鉛直材で挟まれる角度の変化を記録できるものであればよく、その一具体例を実施例１で説明する。 Although FIG. 4 is an example of a two-story building, it can also be used in a building having a plurality of floors such as a one-story building and a three-story building. In addition, it is possible to measure buildings that cannot be handled as a unitary structure, such as an extension or a complicated plane (eg, concave type). Any measuring device may be used as long as it can record a change in the angle between the horizontal member and the vertical member, and one specific example thereof will be described in the first embodiment.
図５（Ａ）は、実施例１に係る耐震又は風圧強度測定装置８を窓枠の上桟２１と縦桟２２に接するように取付けたときの概念図である。図６は、実施例１に係る耐震又は風圧強度測定装置８の突起部３１付近の拡大図である。 FIG. 5A is a conceptual diagram when the earthquake resistance or wind pressure intensity measuring device 8 according to the first embodiment is attached so as to contact the upper frame 21 and the vertical beam 22 of the window frame. FIG. 6 is an enlarged view of the vicinity of the protrusion 31 of the seismic or wind pressure strength measuring device 8 according to the first embodiment.
実施例１に係る耐震又は風圧強度測定装置８は、横支持部材８ａと縦支持部材８ｂとからなるＬ字状部材を備える。Ｌ字状部材に、水平荷重時における層間変形角を直接測定して表示する層間変形角測定手段が設けられる。層間変形角測定手段は、測定ピン２５と、測定ピン２５の位置における、横支持部材８ａと上桟２１との離隔の距離の変化を測定し、これを増幅して角度の変形量として変換する手段（第１のアーム２４，第２のアーム２９，第３のアーム３０，突起物３１）と、上記角度の変形量を一点を固定点として、時計回り又は反時計回りに回転して示す第１の針Ａと第２の針Ｂと、これらの針Ａ，Ｂの回転角度を表示する表示部３３を備える。表示部３３は、第１及び第２の針Ａ，Ｂの後方に設けられる。 The earthquake resistance or wind pressure intensity measuring device 8 according to the first embodiment includes an L-shaped member composed of a horizontal support member 8a and a vertical support member 8b. The L-shaped member is provided with interlayer deformation angle measuring means for directly measuring and displaying the interlayer deformation angle at the time of horizontal load. The interlayer deformation angle measuring means measures a change in the distance between the horizontal support member 8a and the upper rail 21 at the position of the measurement pin 25 and the measurement pin 25, amplifies this, and converts it as an angular deformation amount. Means (first arm 24, second arm 29, third arm 30, projection 31) and the amount of deformation of the angle shown by rotating clockwise or counterclockwise with one point as a fixed point The first needle A, the second needle B, and the display unit 33 that displays the rotation angles of the needles A and B are provided. The display unit 33 is provided behind the first and second hands A and B.
さらに詳細に説明すると、Ｌ字状部材の縦支持部材８ｂは、窓枠の縦桟２２にビス２８で固定される。第１のアーム２４の一方端は、横支持部材８ａに回動点２４ａで回動可能に取付けられている。第１のアーム２４から枝分かれするように、ピン支持部材２６が設けられている。ピン支持部材２６には測定ピン２５が回動可能に取付けられている。測定ピン２５は窓枠が、水平荷重時に変形するとき、上桟２１の上面を変位に追従し転動する。 More specifically, the L-shaped member vertical support member 8b is fixed to the vertical frame 22 of the window frame with screws 28. One end of the first arm 24 is attached to the lateral support member 8a so as to be rotatable at a rotation point 24a. A pin support member 26 is provided so as to branch from the first arm 24. A measurement pin 25 is rotatably attached to the pin support member 26. The measuring pin 25 rolls following the displacement of the upper surface of the upper rail 21 when the window frame is deformed during a horizontal load.
図５（Ａ）と図６を参照して、第１のアーム２４の他方端には、第２のアーム２９の一方端が回動可能に取付けられている。第２のアーム２９の他方端は、第３のアーム３０の一方端に回動可能に取付けられている。第３のアーム３０の他方端は、横支持部材８ａに回動点３０ａで回動可能に取付けられている。 Referring to FIGS. 5A and 6, one end of second arm 29 is rotatably attached to the other end of first arm 24. The other end of the second arm 29 is rotatably attached to one end of the third arm 30. The other end of the third arm 30 is attached to the lateral support member 8a so as to be rotatable at a rotation point 30a.
第２のアーム２９の他方端の近傍には、突起部３１が設けられている。突起部３１は、針Ａの根元から側方に延びる針延長部ａに下から接触し、かつ、針Ｂの根元から側方に延びる針延長部ｂに上から接触する。突起部３１が回転すると、針Ａ又はＢを回転中心３２を中心に回転させる。針Ａ，Ｂの後方には表示部３３が設けられている。表示部３３には突起部３１が通過する、円弧状の通路３３ａが、彫り抜かれている。突起部３１が、円弧状の通路３３ａに沿って、反時計回りに移動すると、突起部３１は、針Ｂの針延長部ｂを押し上げ、これにより針Ｂは回転中心３２を中心にして、反時計方向に回転する。突起部３１が、円弧状の通路３３ａに沿って、下方向（矢印）に移動すると、突起部３１は、針Ａの針延長部ａを押し下げ、これにより針Ａは、回転中心３２を中心にして、時計方向に回転する。 A protrusion 31 is provided in the vicinity of the other end of the second arm 29. The protrusion 31 comes into contact with a needle extension a that extends laterally from the root of the needle A, and comes into contact with a needle extension b that extends laterally from the root of the needle B from above. When the protrusion 31 rotates, the needle A or B is rotated about the rotation center 32. A display unit 33 is provided behind the needles A and B. An arcuate passage 33a through which the protrusion 31 passes is carved out of the display unit 33. When the protruding portion 31 moves counterclockwise along the arc-shaped passage 33a, the protruding portion 31 pushes up the needle extension portion b of the needle B, whereby the needle B rotates counterclockwise around the rotation center 32. Rotate clockwise. When the protruding portion 31 moves downward (arrow) along the arc-shaped passage 33a, the protruding portion 31 pushes down the needle extension portion a of the needle A, whereby the needle A is centered on the rotation center 32. Rotate clockwise.
次に、水平荷重時に、予め定められた位置における、Ｌ字状部材の横支持部材と、窓の上桟との離隔の距離の変化を、角度の変形量に変換する動作について説明する。 Next, an operation for converting a change in the distance between the lateral support member of the L-shaped member and the upper rail of the window at a predetermined position into a deformation amount of an angle during a horizontal load will be described.
図５（Ａ）、図６、図２（Ｂ）を参照して、地震時、窓枠がＡ方向に変形したとする。このとき、測定ピン２５の位置において、Ｌ字状部材の横支持部材８ａと窓枠の上桟２１との離隔の距離は広がる。これにつれて、測定ピン２５は窓枠の上桟２１の上面を転動する。すると第１のアーム２４の他方端は下方向に押し下げられ、第２アーム２９の他方端は下方向に押し下げられ、突起部３１は、通路３３ａに沿って下方向に移動し、針Ａの針延長部ａを押し下げ、これにより針Ａは回転中心３２を中心にして、時計方向に回転する。 Referring to FIGS. 5A, 6 and 2B, it is assumed that the window frame is deformed in the A direction during an earthquake. At this time, at the position of the measurement pin 25, the distance of the separation between the L-shaped lateral support member 8a and the upper frame 21 of the window frame increases. Accordingly, the measuring pin 25 rolls on the upper surface of the upper frame 21 of the window frame. Then, the other end of the first arm 24 is pushed down, the other end of the second arm 29 is pushed down, and the protruding portion 31 moves downward along the passage 33a. The extension a is pushed down, whereby the needle A rotates clockwise around the rotation center 32.
一方窓枠が、逆に変形した場合、即ち、窓枠がＢ方向に、すなわち図２（Ｃ）に示すように変形したとする。このとき、測定ピン２５の位置において、Ｌ字状部材の横支持部材８ａと窓枠の上桟２１との離隔の距離は縮まり、測定ピン２５は窓枠の上桟２１の上面を転動する。すると第１のアーム２４の他方端は上方向に押し上げられ、第２アーム２９の他方端は上方向に押し上げられ、突起部３１は、通路３３ａに沿って上方向に移動し、針Ｂの針延長部ｂを押し上げ、これにより針Ｂは回転中心３２を中心にして、反時計方向に回転する。 On the other hand, it is assumed that the window frame is deformed in the opposite direction, that is, the window frame is deformed in the B direction, that is, as shown in FIG. At this time, at the position of the measurement pin 25, the distance between the lateral support member 8a of the L-shaped member and the upper frame 21 of the window frame is reduced, and the measurement pin 25 rolls on the upper surface of the upper frame 21 of the window frame. . Then, the other end of the first arm 24 is pushed upward, the other end of the second arm 29 is pushed upward, and the protrusion 31 moves upward along the passage 33a. The extension part b is pushed up, whereby the needle B rotates counterclockwise around the rotation center 32.
針Ａ、針Ｂは、建物の復元に基いて窓枠の変形が復元しても、それに追随せず、動いた位置（最大変形角の位置）で留まっており、変形量を履歴として目視できる。 Even if the deformation of the window frame is restored based on the restoration of the building, the needle A and the needle B remain in the moved position (the position of the maximum deformation angle) and can visually check the deformation amount as a history. .
なお、図５（Ｂ）を参照して、第１アーム２４のＬ１とＬ２の長さの比を調節することにより、テコの原理により、横支持部材と上桟との離隔の距離の変化を、角度の変形量に変換する際の、増幅度を調節することができる。 Referring to FIG. 5B, by adjusting the ratio of the lengths L1 and L2 of the first arm 24, the distance between the lateral support member and the upper rail can be changed according to the lever principle. It is possible to adjust the degree of amplification when converting into the amount of deformation of the angle.
図７を参照して、本実施例は、実施例１の変形例に係る。針Ａ、針Ｂは、上述のとおり、動いた位置で留まっており、最大変形角を表示する。一方、家屋の変形はその後弾性力により回復するが、その回復後の状態の現状変形角は針Ａ、針Ｂだけでは表示できない。そこで、実施例２では、図７に示すように、針Ａ、針Ｂに加えて、現状変形角を表示させる針Ｃを設ける。針Ｃの針延長部ｃは２つに分枝し、突起物３１を挟むようになっている。針Ａ、針Ｂ、針Ｃのうち、針Ｃは最背位に配置させる。地震時、針Ｃは、突起物３１の押圧により、針Ａ又は針Ｂと同じ変位まで、回転する。さて、突起物３１は、家屋の変形が弾性力によりある程度回復する（この回復した時の家屋の変形角を現状変形角という）と、現状変形角の位置まで戻る。すると針Ｃの延長部ｃは、延長部ｃが挟んでいる突起物３１とともに、突起物３１が戻る位置まで押し戻される。これによって、針Ｃは、現状変形角を表示することになる。 With reference to FIG. 7, the present embodiment relates to a modification of the first embodiment. As described above, the needle A and the needle B remain in the moved position and display the maximum deformation angle. On the other hand, the deformation of the house is then recovered by the elastic force, but the current deformation angle in the state after the recovery cannot be displayed only with the needle A and the needle B. Therefore, in Example 2, in addition to the needle A and the needle B, a needle C for displaying the current deformation angle is provided as shown in FIG. The needle extension portion c of the needle C is branched into two and sandwiches the protrusion 31. Of the needle A, the needle B, and the needle C, the needle C is disposed at the most back position. During an earthquake, the needle C rotates to the same displacement as the needle A or the needle B due to the pressing of the protrusion 31. The protrusion 31 returns to the position of the current deformation angle when the deformation of the house recovers to some extent by the elastic force (the deformation angle of the house at the time of recovery is referred to as the current deformation angle). Then, the extension portion c of the needle C is pushed back to the position where the projection 31 returns together with the projection 31 sandwiched by the extension c. As a result, the needle C displays the current deformation angle.
本実施例は、実施例１のさらなる変形例に係る。本実施例では、図６又は図７の構成に加えて、針Ａ，Ｂが危険ゾーンに入ったときに警告音が鳴るように構成する。例えば針Ａ，Ｂが危険ゾーンに入った時に、上記針延長部ａ，ｂが、例えばブザーのスイッチ（図示せず）を押す構成にすると、ブザーが鳴り続ける。これは、次回の地震時には倒壊することの警告となる。 The present embodiment relates to a further modification of the first embodiment. In this embodiment, in addition to the configuration of FIG. 6 or FIG. 7, a warning sound is generated when the hands A and B enter the danger zone. For example, when the needles A and B enter the danger zone, if the needle extensions a and b are configured to press a buzzer switch (not shown), for example, the buzzer continues to sound. This is a warning that the next earthquake will collapse.
本実施例は、実施例１のさらなる変形例に係る。図８（Ａ）は、実施例４に係る、ラックアンドピニオン構造を有する耐震又は風圧強度測定装置を窓に取付けたときの概念図である。実施例４に係る、耐震又は風圧強度測定装置は、図５実施例と以下の点を除いて、同一であるので、同一又は相当する部分には同一の参照番号を付し、その説明を繰り返さない。図８（Ｂ）はラックアンドピニオン構造部を抜き出して示した分解図であり、図８（Ｃ）は表示部３３を抜き出して、説明の便宜上拡大して示した分解図である。 The present embodiment relates to a further modification of the first embodiment. FIG. 8A is a conceptual diagram when an earthquake-proof or wind-pressure strength measuring device having a rack and pinion structure according to Example 4 is attached to a window. Since the seismic resistance or wind pressure intensity measuring apparatus according to the fourth embodiment is the same as the embodiment shown in FIG. 5 except for the following points, the same or corresponding parts are denoted by the same reference numerals, and the description thereof is repeated. Absent. FIG. 8B is an exploded view showing the rack and pinion structure part extracted, and FIG. 8C is an exploded view showing the display part 33 extracted and enlarged for convenience of explanation.
これらの図を参照して、実施例１と異なる点は、予め定められた位置における、Ｌ字状部材の横支持部材８ａと窓枠の上桟２１との離隔の距離の変化を増幅して角度の変形量として変換する機構が、ラックギア４１とピニオンギア４２を含むラックアンドピニオン構造で構成している点である。 Referring to these drawings, the difference from the first embodiment is that a change in the distance between the L-shaped lateral support member 8a and the upper frame 21 of the window frame at a predetermined position is amplified. The mechanism for converting the amount of deformation of the angle is a rack and pinion structure including a rack gear 41 and a pinion gear 42.
ピニオンギア４２の回転中心４２ａと、突起物３１がその他方端に固定されたアーム３０の一方端は、回転中心３０ａで回動可能に、連結部材４３で連結されている。アーム３０が回転中心３０ａを中心に回転すると、突起部３１は、円弧状の通路３３ａに沿って上下方向に動く。突起部３１が、円弧状の通路３３ａに沿って、上方向に移動すると、突起部３１は、針Ｂの針延長部ｂを押し上げ、これにより針Ｂは回転中心３０ａを中心にして、反時計方向に回転する。突起部３１が、円弧状の通路３３ａに沿って、下方向（矢印）に移動すると、突起部３１は、針Ａの針延長部ａを押し下げ、これにより針Ａは、回転中心３０ａを中心にして、時計方向に回転する。 The rotation center 42a of the pinion gear 42 and one end of the arm 30 to which the protrusion 31 is fixed at the other end are connected by a connecting member 43 so as to be rotatable at the rotation center 30a. When the arm 30 rotates around the rotation center 30a, the protrusion 31 moves in the vertical direction along the arc-shaped passage 33a. When the protrusion 31 moves upward along the arc-shaped passage 33a, the protrusion 31 pushes up the needle extension b of the needle B, whereby the needle B is counterclockwise around the rotation center 30a. Rotate in the direction. When the protruding portion 31 moves downward (arrow) along the arc-shaped passage 33a, the protruding portion 31 pushes down the needle extension portion a of the needle A, whereby the needle A is centered on the rotation center 30a. Rotate clockwise.
次に動作について説明する。図８（Ａ）（Ｂ）（Ｃ）と図２（Ｂ）を参照して、地震時、窓枠がＡ方向に、変形したとする。このとき、ラックギア４１が存在する位置における、Ｌ字状部材の横支持部８ａと窓枠の上桟２１との離隔の距離は広がる。これにつれて、ラックギア４１は下方向に降りる。するとピニオンギア４２が回転中心４２ａを中心に時計方向に回転し、連結部材４３が時計方向に回転する。すると、アーム３０の他方端は下方向に押し下げられ、突起部３１は、通路３３ａに沿って下方向に移動し、針Ａの針延長部ａを押し下げ、これにより針Ａは回転中心３０ａを中心にして、時計方向に回転する。 Next, the operation will be described. Referring to FIGS. 8A, 8B, 8C and 2B, it is assumed that the window frame is deformed in the A direction during an earthquake. At this time, the distance between the L-shaped member lateral support portion 8a and the upper frame 21 of the window frame at the position where the rack gear 41 is present increases. As a result, the rack gear 41 descends downward. Then, the pinion gear 42 rotates clockwise around the rotation center 42a, and the connecting member 43 rotates clockwise. Then, the other end of the arm 30 is pushed downward, and the protrusion 31 moves downward along the passage 33a to push down the needle extension part a of the needle A, whereby the needle A is centered on the rotation center 30a. And rotate clockwise.
一方、図８（Ａ）（Ｂ）（Ｃ）と図２（Ｃ）を参照して、地震時、窓枠が上とは逆方向に、変形したとする。このとき、Ｌ字状部材の横支持部材と窓枠の上桟２１との離隔の距離は縮まる。これにつれて、ラックギア４１は上方向に昇る。するとピニオンギア４２が回転中心４２ａを中心に反時計方向に回転し、連結部材４３が反時計方向に回転する。すると、アーム３０の他方端は上方向に押し上げられ、突起部３１は、通路３３ａに沿って上方向に移動し、針Ｂの針延長部ｂを押し上げ、これにより針Ｂは回転中心３０ａを中心にして反時計方向に回転する。 On the other hand, with reference to FIGS. 8 (A), (B), (C) and FIG. 2 (C), it is assumed that the window frame is deformed in the opposite direction to the top during an earthquake. At this time, the distance between the lateral support member of the L-shaped member and the upper frame 21 of the window frame is reduced. As a result, the rack gear 41 rises upward. Then, the pinion gear 42 rotates counterclockwise around the rotation center 42a, and the connecting member 43 rotates counterclockwise. Then, the other end of the arm 30 is pushed upward, the protrusion 31 moves upward along the passage 33a, pushes up the needle extension b of the needle B, and thereby the needle B is centered on the rotation center 30a. And rotate counterclockwise.
