Description

本発明はターンバックルに関する。さらに詳しくは、減衰機能を有するターンバックルに関する。   The present invention relates to a turnbuckle. More specifically, the present invention relates to a turnbuckle having a damping function.

阪神淡路大震災において木造住宅が多く倒壊した教訓を受けて、木造住宅の耐震性の向上を図ることがなされている。   In response to the lessons learned from the collapse of many wooden houses in the Great Hanshin Earthquake, efforts have been made to improve the earthquake resistance of wooden houses.

この耐震性の向上を図る一手段として、仕口に衝撃吸収力を持たせるようにすることがなされている。例えば、図５に示すように、仕口５０に仕口ダンパー６０を設けることがなされている。図中、符号７０は基礎を示し、符号８０は土台を示す。   As a means for improving the seismic resistance, the joint is made to have an impact absorbing ability. For example, as shown in FIG. 5, a joint damper 60 is provided in the joint 50. In the figure, reference numeral 70 indicates the foundation, and reference numeral 80 indicates the foundation.

図６に、仕口ダンパー６０の一例を示す。仕口ダンパー６０は、図６に示すように、柱５１に取り付けられる柱側鋼板６１と、梁５２に取り付けられる梁側鋼板６２と、その間に密着される粘弾性体６３とからなるものとされる。   FIG. 6 shows an example of the joint damper 60. As shown in FIG. 6, the joint damper 60 includes a column side steel plate 61 attached to the column 51, a beam side steel plate 62 attached to the beam 52, and a viscoelastic body 63 in close contact therebetween. The

この仕口ダンパー６０を仕口５０に設けることにより、地震などによる住宅の揺れが粘弾性体により吸収され、住宅の倒壊が防止される。   By providing the joint damper 60 in the joint 50, the shaking of the house due to an earthquake or the like is absorbed by the viscoelastic body, and the house is prevented from collapsing.

しかしながら、仕口ダンパー６０を設けた場合には、その取付作業が必要となり、しかもそれが従来の作業にない余分な作業であるため、施工が煩雑となり、かつ、施工の長期化を招来するという問題がある。この施工の長期化という問題は、迅速な施工が要求される既設住宅の耐震補強を図る際に大きな問題となる。   However, when the joint damper 60 is provided, its installation work is required, and since it is an extra work that does not exist in the conventional work, the construction becomes complicated and the construction is prolonged. There's a problem. This problem of prolonged construction is a major problem when retrofitting existing houses that require rapid construction.

本発明はかかる従来技術の課題に鑑みさなれたものであって、従来の施工手順によりながら、住宅とりわけ木造住宅の耐震性を向上させるターンバックルを提供することを目的としている。   The present invention has been made in view of the problems of the prior art, and an object of the present invention is to provide a turnbuckle that improves the earthquake resistance of a house, particularly a wooden house, according to a conventional construction procedure.

本発明のターンバックルは、ロッド状ブレースからの振動を減衰させる減衰部材を備えてなることを特徴とする。   The turnbuckle of the present invention includes a damping member that attenuates vibration from the rod-shaped brace.

本発明のターンバックルの第１形態は、本体と減衰部材とナットとを備えてなるターンバックルであって、前記本体は両端部にロッド状ブレースが挿通される透孔を有し、前記本体の空間部の幅は、ナットが本体のサイドから挿入はされるが、回転しないようにされ、前記減衰部材は、前記ロッド状ブレースが挿通される透孔が先端から後端に向けて貫通形成され、前記減衰部材の形状は、前記本体内面に沿うようにされてなることを特徴とする。   A first form of the turnbuckle of the present invention is a turnbuckle comprising a main body, a damping member, and a nut, the main body having a through hole through which a rod-shaped brace is inserted at both ends, The width of the space is such that the nut is inserted from the side of the main body, but is not rotated, and the damping member is formed with a through hole through which the rod-shaped brace is inserted from the front end toward the rear end. The shape of the damping member is adapted to be along the inner surface of the main body.

本発明のターンバックルの第２形態は、本体と減衰部材とナットとを備えてなるターンバックルであって、前記本体は両端部にロッド状ブレースが挿通される透孔を有し、前記減衰部材は角筒体とされて前記ナットの外周に密着させて配設され、前記減衰部材の辺の長さは、該減衰部材が本体のサイドから挿入はされるが、回転しないようにされてなることを特徴とする。   A second form of the turnbuckle of the present invention is a turnbuckle comprising a main body, a damping member, and a nut, and the main body has a through hole through which a rod-shaped brace is inserted at both ends, and the damping member Is a square cylinder and is disposed in close contact with the outer periphery of the nut, and the length of the side of the damping member is such that the damping member is inserted from the side of the main body but does not rotate. It is characterized by that.

しかして、本発明のターンバックルは、住宅の耐震補強に用いられる。   Thus, the turnbuckle of the present invention is used for seismic reinforcement of a house.

本発明によれば、従来のターンバックル補強と同様の施工手順により住宅の耐震性を向上できるという優れた効果を奏する。   According to the present invention, there is an excellent effect that the earthquake resistance of the house can be improved by the same construction procedure as that of the conventional turnbuckle reinforcement.

以下、添付図面を参照しながら本発明を実施形態に基づいて説明するが、本発明はかかる実施形態のみに限定されるものではない。   Hereinafter, although the present invention is explained based on an embodiment, referring to an accompanying drawing, the present invention is not limited only to this embodiment.

実施形態１
図１に、本発明の実施形態１に係るターンバックルが適用された木造住宅の軸組を概略図で示す。この木造住宅は、図１に示すように、ロッド状ブレース１をターンバックル１０により張設して横揺れ防止を図ってなるものである。 Embodiment 1
FIG. 1 is a schematic view showing a wooden house framework to which a turnbuckle according to Embodiment 1 of the present invention is applied. As shown in FIG. 1, this wooden house has a rod-shaped brace 1 stretched by a turnbuckle 10 to prevent rolling.

図２および図３に、ターンバックル１０の詳細を示す。なお、図１中、符号２は柱を示し、符号３は梁を示し、符号４は基礎を示し、符号５は土台を示す。   2 and 3 show the details of the turnbuckle 10. In FIG. 1, reference numeral 2 indicates a pillar, reference numeral 3 indicates a beam, reference numeral 4 indicates a foundation, and reference numeral 5 indicates a base.

ターンバックル１０は、図２および図３に示すように、本体１２と、減衰部材１４と、ナット１６とを主要構成要素として備えてなる。   As shown in FIGS. 2 and 3, the turnbuckle 10 includes a main body 12, a damping member 14, and a nut 16 as main components.

本体１２は、基本的には通常のターンバックルに用いられているものと同様とされているが、ロッド状ブレース１が挿通される透孔１２ａは、ブレース１端部に形成されている雄ねじ１ａと螺合する雌ねじが形成されておらず、単なる透孔されている点が異なる。また、本体１２の空間部１２ｂの幅ｗは、ナット１６をサイドから挿入はできるが、ナット１６が回転しないように調整されている。   The main body 12 is basically the same as that used for a normal turnbuckle, but the through hole 12a through which the rod-shaped brace 1 is inserted is a male screw 1a formed at the end of the brace 1. There is a difference in that a female screw is not formed and is simply perforated. The width w of the space 12b of the main body 12 is adjusted so that the nut 16 can be inserted from the side, but the nut 16 does not rotate.

減衰部材１４は例えば低反発性のスポンジや防振ゴムなどからなる先端部が円錐台状とされた円筒体とされ、ロッド状ブレース１が挿通される透孔１４ａが先端から後端に向けて貫通形成されている。また、減衰部材１４の形状は、本体１２の端部内面に沿うようにされている。   The damping member 14 is a cylindrical body having a truncated cone shape at the front end portion made of, for example, a low resilience sponge or vibration proof rubber, and a through hole 14a through which the rod-shaped brace 1 is inserted is directed from the front end toward the rear end. It is formed through. Further, the shape of the attenuation member 14 is adapted to be along the inner surface of the end portion of the main body 12.

ナット１６はブレース１端部に形成されている雄ねじ１ａと螺合するようにされた、例えば六角ナットとされる。   The nut 16 is, for example, a hexagonal nut adapted to be screwed into a male screw 1a formed at the end of the brace 1.

次に、かかる構成とされたターンバックル１０による住宅の耐震補強の一例について説明する。   Next, an example of the earthquake-proof reinforcement of the house by the turnbuckle 10 having such a configuration will be described.

手順１：本体１２の一端部に一方のブレース１Ａの雄ねじ１ａが形成された基端部を挿通し、他端部に他方のブレース１Ｂの雄ねじ１ａが形成された基端部を挿通する。   Procedure 1: One end of the main body 12 is inserted through the base end portion where the male screw 1a of one brace 1A is formed, and the other end portion is inserted through the base end portion where the male screw 1a of the other brace 1B is formed.

手順２：ブレース１Ａ，１Ｂの基端部に減衰部材１４を挿通した後、ナット１６を仮留めする。   Procedure 2: After the damping member 14 is inserted into the base ends of the braces 1A and 1B, the nut 16 is temporarily fixed.

手順３：一方のブレース１Ａの先端を仕口部例えば上方の仕口部に常法により取り付け、他方のブレース１Ｂの先端を対角に位置する仕口部例えば対角下方の仕口部に常法により取り付ける。   Step 3: The front end of one brace 1A is attached to a joint part, for example, an upper joint part in a conventional manner, and the front end of the other brace 1B is always attached to a joint part located diagonally, for example, a joint part below the diagonal. Install by law.

手順４：ターンバックル１０、具体的には本体１２を回転させてブレース１Ａ，１Ｂを張設する。   Procedure 4: The turnbuckle 10, specifically the main body 12, is rotated to stretch the braces 1A and 1B.

これにより、地震時に住宅が揺れた場合には、その揺れによる振動が減衰部材１２により吸収されるので、住宅の耐震性が向上する。なお、ブレース１の強度は従来と同様にブレース１の軸部の破断力により決定されるので、減衰機能を付与したことによる強度低下は招来しない。   Thereby, when a house shakes at the time of an earthquake, since the vibration by the shake is absorbed by the damping member 12, the earthquake resistance of the house is improved. In addition, since the intensity | strength of the brace 1 is determined by the breaking force of the axial part of the brace 1 similarly to the past, the intensity | strength fall by giving a damping function will not be caused.

このように、この実施形態１のターンバックル１０によれば、強度低下を生ずることなく、従来のターンバックルによる住宅の揺れに対する補強手順とほぼ同様の手順により住宅の耐震補強がなし得る。そのため、施工の迅速性が要求される既設木造住宅の耐震補強に好適である。   As described above, according to the turnbuckle 10 of the first embodiment, the earthquake-proof reinforcement of the house can be achieved by a procedure substantially similar to the reinforcement procedure for the shaking of the house due to the conventional turnbuckle without causing a decrease in strength. Therefore, it is suitable for seismic reinforcement of existing wooden houses that require rapid construction.

実施形態２
図４に、本発明の実施形態２に係るターンバックル２０を示す。このターンバックル２０は実施形態１のターンバックル１０を改変してなるものであって、ブレース１の基端部に螺合されるナット２４と、その外周に密着させて配設された減衰部材２６とを主要構成要素として備えてなる。 Embodiment 2
FIG. 4 shows a turnbuckle 20 according to Embodiment 2 of the present invention. The turnbuckle 20 is obtained by modifying the turnbuckle 10 of the first embodiment, and includes a nut 24 screwed into the base end portion of the brace 1 and a damping member 26 disposed in close contact with the outer periphery thereof. And as a main component.

減衰部材２４は例えば粘弾性体かなる角筒体とされ、その辺の長さは減衰部材２４を本体２２にサイドから挿入はできるが回転しないように調整されている
次に、かかる構成とされたターンバックル２０による住宅の耐震補強の一例について説明する。 The damping member 24 is, for example, a rectangular tube made of a viscoelastic body, and the length of the side thereof is adjusted so that the damping member 24 can be inserted into the main body 22 from the side but does not rotate. An example of the earthquake-proof reinforcement of the house by the turnbuckle 20 will be described.

手順１：本体２２の一端部に一方のブレース１Ａの雄ねじ１ａが形成された基端部を挿通し、他端部に他方のブレース１Ｂの雄ねじが形成された基端部を挿通する。   Procedure 1: One end of the main body 22 is inserted through the base end portion where the male screw 1a of one brace 1A is formed, and the other end portion is inserted through the base end portion where the male screw of the other brace 1B is formed.

手順２：ブレース１Ａ，１Ｂの基端部に外周に減衰部材２６が配設されたナット２４を仮留めする。   Procedure 2: Temporarily fasten the nut 24 having the damping member 26 disposed on the outer periphery to the base ends of the braces 1A and 1B.

手順３：一方のブレース１Ａの先端を仕口部例えば上方の仕口部に常法により取り付け、他方のブレース１Ｂの先端を対角に位置する仕口部例えば対角下方の仕口部に常法により取り付ける。   Step 3: The front end of one brace 1A is attached to a joint part, for example, an upper joint part in a conventional manner, and the front end of the other brace 1B is always attached to a joint part located diagonally, for example, a joint part below the diagonal. Install by law.

手順４：ターンバックル２０、具体的には本体２２を回転させてブレース１Ａ，１Ｂを張設する。   Procedure 4: The turnbuckle 20, specifically, the main body 22 is rotated to stretch the braces 1A and 1B.

これにより、地震時に住宅が揺れた場合には、その揺れによる振動でナット２４と減衰部材２６との間にせん断抵抗が発生して振動が吸収されるので、住宅の耐震性が向上する。なお、ブレース１の強度は従来と同様にブレース１の軸部の破断力により決定されるので、減衰機能を付与したことによる強度低下は招来しない。   Thereby, when a house shakes at the time of an earthquake, a shear resistance is generated between the nut 24 and the damping member 26 due to the vibration caused by the shake and the vibration is absorbed, so that the earthquake resistance of the house is improved. In addition, since the intensity | strength of the brace 1 is determined by the breaking force of the axial part of the brace 1 similarly to the past, the intensity | strength fall by giving a damping function will not be caused.

このように、この実施形態２のターンバックル２０によれば、強度低下を生ずることなく、従来のターンバックルによる住宅の揺れに対する補強手順とほぼ同様の手順により住宅の耐震補強がなし得る。そのため、施工の迅速性が要求される既設木造住宅の耐震補強に好適である。   As described above, according to the turnbuckle 20 of the second embodiment, the earthquake-proof reinforcement of the house can be performed by a procedure substantially similar to the reinforcement procedure for the shaking of the house due to the conventional turnbuckle without causing a decrease in strength. Therefore, it is suitable for seismic reinforcement of existing wooden houses that require rapid construction.

本発明は耐震補強が必要とされる住宅、とりわけ木造住宅に適用できる。   The present invention can be applied to a house that requires seismic reinforcement, in particular, a wooden house.
