Description

本発明は、ブレースの支持体の構造に関するものである。
The present invention relates to the structure of a brace support.

建築のRC造、SRC造、S造のラーメン構造の柱部分にブレースを取り付ける構造として各種のものが開発されている。
その場合に、ブレースの端部をどのように柱に取り付けるか、が技術上の問題となる。
その解決策として、柱にバンド状に補強プレートを巻きつけて設置し、このプレート間にダンパーを取り付ける構造が知られている。
その際に、このバンド状の補強プレートをどのように柱に設置するか、がさらに問題となる。
そのため、例えば引用文献1のように、柱と梁の接合部に、上下階に亘りPC鋼棒で締め付けてブレースを固定する方法、あるいは引用文献2のように、柱の4面にプレートを配置し、柱内を貫通させたPC鋼棒で対向面のプレートを締め付けて固定する方法などが知られている。
Various structures have been developed for attaching braces to the pillar portions of RC structures, SRC structures, and S frame structures.
In that case, how to attach the end of the brace to the pillar is a technical problem.
As a solution, a structure is known in which a reinforcing plate is wound around a pillar in a band shape and a damper is attached between the plates.
At that time, how to install the band-shaped reinforcing plate on the column becomes a further problem.
Therefore, for example, as in Cited Document 1, a method of fixing braces by fastening with PC steel bars across the upper and lower floors at the joint between the pillar and beam, or arranging plates on the four sides of the pillar as in Cited Document 2 In addition, a method is known in which a plate on the opposite surface is fastened and fixed with a PC steel rod penetrating the column.

特開2003−13614号公報。Japanese Patent Laid-Open No. 2003-13614. 特許第3559025号公報。Japanese Patent No. 3559025.

前記した従来のブレースの支持体の構造にあっては、次のような問題点がある。
<1>引用文献1記載の発明では、施工する階が上下に亘るために工事範囲が大規模になり、経済的、工期的に負担が大きくなる。
またスラブを貫通させたPC鋼棒を締め付けるために、防火区画や建物用途により防水や遮音の問題が生じる。
<2>引用文献2記載の発明では、既存柱を貫通して削孔するため、主筋やせん断補強筋を切断してしまう可能性があり、切断してしまうと補強どころか弱点になってしまう。
The conventional brace support structure described above has the following problems.
<1> In the invention described in the cited document 1, since the floors to be constructed extend vertically, the construction range becomes large, and the burden is increased economically and on the construction schedule.
Moreover, in order to fasten the PC steel bar which penetrated the slab, the problem of waterproofing or sound insulation arises by a fire prevention zone or a building use.
<2> In the invention described in the cited document 2, since the hole is drilled through the existing column, there is a possibility that the main reinforcing bar or the shear reinforcing bar may be cut, and if cut, it becomes a weak point rather than a reinforcement.

上記のような課題を解決するために、本発明のブレースの支持体の構造は、柱の対向面に平行に配置する側板と、側板間に、側板と直交する方向に取り付けた受圧体と、側板間に、側板と直交する方向に配置し、対象とする柱を挟む状態で柱の両面に配置する緊張材と、側板の柱側の面に取り付けたアルミ板とより構成し、受圧体においてブレースやダンパーの力を受けるように構成したものである。
さらに本発明のブレースの支持体の構造は、上記の支持体の側板の外部に補強材を取り付けて構成し、その取り付け位置は、前記の緊張材間であって支持体を柱に取り付けた場合にほぼ水平方向となる位置である。
In order to solve the problems as described above, the structure of the brace support of the present invention includes a side plate arranged in parallel to the opposing surface of the column, a pressure receiving body attached between the side plates in a direction perpendicular to the side plate, Between the side plates, arranged in a direction orthogonal to the side plates, and composed of a tension material arranged on both sides of the column with the target column in between, and an aluminum plate attached to the column side surface of the side plate, It is configured to receive the power of braces and dampers.
Furthermore, the structure of the support body of the brace of the present invention is configured by attaching a reinforcing material to the outside of the side plate of the support body, and the attachment position is between the above-mentioned tension materials and the support body is attached to the column It is a position that is almost horizontal.

本発明のブレースの支持体の構造は以上説明したようになるから次のような効果を得ることができる。
<1> 柱の対向する平行面を両側から側板で押えて、側板と柱との摩擦抵抗によってブレースやダンパーの外力を受ける構造である。
<2> したがって柱を両面から押える力を、柱の強度に適合した大きさに調整してブレースなどの外力を受けることができる。
<3> 支持体の柱への取り付け強度が過度に大きいと、柱の支持体の取り付け部が破壊してしまう可能性がある。しかし本発明の構造では一定以上の外力を受けると側板が滑るように調整できるから、柱を破壊することがない。
<4> 配筋の複雑な柱に削孔するような加工を加えず、その外から取り付ける構造であるから、配筋を切断するような可能性がまったくなく、信頼性の高いものである。
<5> 支持体の取り付けは補強対象の階のみであって上下階にわたることがないから工事範囲が狭く、建物所有者や使用者の負担を最小限度に抑えることができる。
Since the structure of the brace support of the present invention is as described above, the following effects can be obtained.
<1> The structure is such that the parallel surfaces of the columns facing each other are pressed by the side plates from both sides and the external force of the braces and dampers is received by the frictional resistance between the side plates and the columns.
<2> Therefore, the force for pressing the column from both sides can be adjusted to a size suitable for the strength of the column to receive an external force such as a brace.
<3> If the attachment strength of the support to the pillar is excessively large, the attachment portion of the support of the pillar may be destroyed. However, in the structure of the present invention, the side plate can be adjusted so as to slide when subjected to an external force exceeding a certain level, so that the column is not broken.
<4> Since it is a structure that is attached from the outside without adding a drilling process to a complicated column of the bar arrangement, there is no possibility of cutting the bar arrangement and it is highly reliable.
<5> Since the support is attached only to the floor to be reinforced and does not extend to the upper and lower floors, the construction range is narrow, and the burden on the building owner and the user can be minimized.

以下図面を参照しながら本発明の好適な実施の形態を詳細に説明する。   DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

<1>本発明の対象。
本発明のブレースやダンパーなどの支持体Sは、 建築のRC造、SRC造、S造のラーメン構造の柱C部分にブレースBを取り付ける際に使用する部材である。
既存の建物の柱Cに取り付けて使用できるだけでなく、新設の建物においても、配筋の複雑な柱Cに貫通する部材がない、という利点からそのまま使用することができる。
<1> Subject of the present invention.
The support S such as a brace or a damper according to the present invention is a member used when the brace B is attached to the column C portion of the RC structure of the building, the SRC structure, or the S frame structure.
Not only can it be used by being attached to a pillar C of an existing building, but it can also be used as it is in a new building because of the advantage that there is no member penetrating through the complicated pillar C of the bar arrangement.

<2>側板。
側板1は、柱Cの対向面に平行に配置する鋼製の板である。
2枚の側板1は、同一の形状を呈する。
側板1の一部は、柱固定部11は柱Cへの取り付け部として機能する。
したがって柱固定部11の長さは、柱Cの水平方向の外寸法よりも大きく構成する。
側板1の柱固定部11以外の残りの部分は、後述する受圧体2を介して外力を受ける受圧部12として機能させる。
<2> Side plate.
The side plate 1 is a steel plate disposed in parallel with the opposing surface of the column C.
The two side plates 1 have the same shape.
In part of the side plate 1, the column fixing portion 11 functions as a mounting portion to the column C.
Accordingly, the length of the column fixing portion 11 is configured to be larger than the outer dimension of the column C in the horizontal direction.
The remaining part other than the column fixing part 11 of the side plate 1 is caused to function as a pressure receiving part 12 that receives an external force via the pressure receiving body 2 described later.

<3>受圧体。
2枚の側板1の受圧部12の間に、側板1と直交する方向に受圧体2を取り付ける。
この受圧体2は例えばH型鋼を利用できる。このH型鋼の端面を側板1の間にボルトで取り付ける。
この受圧体2の長さ、すなわち側板1と側板1の内寸法は、柱Cの水平方向の外寸法よりわずかに長い寸法に設定する。
この受圧体2の外側には、係合板21を突設する。
この係合板21にはピン穴を開口し、このピン穴を介してブレースBやダンパーの端部を係合して取り付ける。
<3> Pressure receiver.
The pressure receiving body 2 is attached between the pressure receiving portions 12 of the two side plates 1 in a direction orthogonal to the side plates 1.
For example, H-shaped steel can be used as the pressure receiving body 2. The end face of the H-shaped steel is attached between the side plates 1 with bolts.
The length of the pressure receiving body 2, that is, the inner dimension of the side plate 1 and the side plate 1 is set to a dimension slightly longer than the outer dimension of the column C in the horizontal direction.
On the outside of the pressure receiving body 2, an engagement plate 21 is projected.
A pin hole is opened in the engagement plate 21, and the brace B and the end of the damper are engaged and attached through the pin hole.

<4>緊張材。
側板1の柱固定部11には、緊張材3を貫通する穴を開口し、この穴に緊張材3を貫通させて設置する。
この緊張材3は、たとえばPC鋼棒を採用し、側板1と直交する方向に配置する。
そして緊張材3は、支持体Sの取り付けの対象とする柱Cを挟む状態で柱Cの両面に配置する。
すなわち、柱Cは一組の対向面に位置する側板1と、他の一組の対向面に位置する緊張材3によって包囲する。
そして緊張材3に緊張を与えることによって、側板1を柱Cに強固に固定することができる。
このように緊張材3の位置を柱Cの外側とすることによって、柱Cへの貫通孔の削孔工程が不要となった。
そのために工期が短縮するだけでなく、柱C内部の鉄筋を切断してしまう可能性もなく信頼性の高い支持方法を提供できる。
<4> Tendon.
A hole that penetrates the tendon 3 is opened in the column fixing portion 11 of the side plate 1, and the tendon 3 is inserted through the hole.
This tendon 3 employs, for example, a PC steel rod and is arranged in a direction orthogonal to the side plate 1.
And the tension material 3 is arrange | positioned on both surfaces of the pillar C in the state which pinches | interposes the pillar C which is the object of attachment of the support body S.
That is, the column C is surrounded by the side plate 1 located on one set of facing surfaces and the tension material 3 located on the other set of facing surfaces.
The side plate 1 can be firmly fixed to the column C by applying tension to the tension member 3.
Thus, by setting the position of the tendon 3 to the outside of the column C, the step of drilling a through hole into the column C becomes unnecessary.
Therefore, not only the work period is shortened but also a reliable support method can be provided without the possibility of cutting the reinforcing bars inside the column C.

<5>アルミ板。
本発明の支持体Sは、地震時に生じるブレースBの軸力を、支持体Sと柱Cの接合面に生じる摩擦力で抵抗することを特徴としている。
そこで支持体Sと柱Cの摩擦力を向上させるために、側板1の柱C側の面には、アルミ合金板4を取り付ける。
するとアルミ合金板4を採用しない場合と比較して33%の摩擦力の向上が図れることが分かった。
また鋼材と鋼材との摩擦係数は0.45であるのに対し、アルミ合金板4にクロム処理をほどこした場合には0.60まで向上することが実験によって確認できた。
そこで本発明の側板1の柱C側の面を赤錆状態とし、一方アルミ合金板4の側板1に面する表面は素地にクロム処理を施す。
さらにアルミ合金板4の柱C側の面、すなわち摩擦面はグリットブラストRz50μにクロム処理を施す。
このように構成することによって大きな摩擦抵抗が得られることが実験によって分かった。
このよう大きな摩擦抵抗が得られることによって、側板1を柱Cに固定するための緊張材3の直径を小さくしたり、本数を低減でき、施工性の向上とコスト低減を図ることができる。
<5> Aluminum plate.
The support S of the present invention is characterized in that the axial force of the brace B generated during an earthquake is resisted by the frictional force generated on the joint surface between the support S and the column C.
Therefore, in order to improve the frictional force between the support S and the column C, an aluminum alloy plate 4 is attached to the surface of the side plate 1 on the column C side.
Then, it was found that the frictional force can be improved by 33% compared to the case where the aluminum alloy plate 4 is not used.
In addition, the friction coefficient between the steel material and the steel material is 0.45, but when the aluminum alloy plate 4 is subjected to chrome treatment, it can be confirmed that the friction coefficient is improved to 0.60.
Therefore, the surface of the side plate 1 of the present invention on the column C side is in a red rust state, while the surface of the aluminum alloy plate 4 facing the side plate 1 is subjected to chromium treatment.
Further, the surface of the aluminum alloy plate 4 on the column C side, that is, the friction surface, is subjected to chromium treatment on the grit blast Rz50μ.
It has been experimentally found that a large frictional resistance can be obtained by such a configuration.
By obtaining such a large frictional resistance, the diameter of the tension material 3 for fixing the side plate 1 to the column C can be reduced, the number of the tension members 3 can be reduced, and workability can be improved and the cost can be reduced.

<6>補強材。
側板1を柱Cに取り付ける場合には、柱Cの両側に位置するPC鋼棒などの緊張材3に緊張を与えて行う。
その場合に側板1の強度が不十分であると、側板1は柱Cの両側に位置する緊張材3貫通部分で絞られて、中央部が柱Cの表面から離れるような形状に変形する可能性がある。
そこで図2に示すように、側板1の外部表面にL型チャンネルやH型鋼などの補強材5を取り付ける構成を採用することもできる。
この補強材5の取り付け方向、取り付け位置は、支持体Sを柱Cに取り付けた場合にほぼ水平方向であり、緊張材3の取り付け位置の間である。
<6> Reinforcing material.
When the side plate 1 is attached to the column C, tension is applied to the tension member 3 such as a PC steel rod located on both sides of the column C.
In this case, if the strength of the side plate 1 is insufficient, the side plate 1 can be squeezed by the tension material 3 penetrating portions located on both sides of the column C and deformed into a shape in which the central portion is separated from the surface of the column C. There is sex.
Therefore, as shown in FIG. 2, a configuration in which a reinforcing material 5 such as an L-shaped channel or H-shaped steel is attached to the outer surface of the side plate 1 can be employed.
The attachment direction and attachment position of the reinforcing member 5 are substantially horizontal when the support S is attached to the column C, and are between the attachment positions of the tension members 3.

<7>支持体Sの取り付け方法。
次に上記で説明した支持体Sを柱Cに取り付ける方法について説明する。
<7> A method of attaching the support S.
Next, a method for attaching the support S described above to the column C will be described.

<8>アルミ合金板4の取り付け。
側板1の柱C側の面にアルミ合金板4を取り付ける。
そのための取り付け方法として例えばアルミ合金板4をビス止めし、周辺をテープで止水養生する。
この理由は、側板1の鋼材とアルミ合金板4との間に後から充填材を充填するのであるが、それがモルタルであった場合にはそのモルタルの水分が侵入して電食が生じないようにするためである。
<8> Attaching the aluminum alloy plate 4.
The aluminum alloy plate 4 is attached to the surface of the side plate 1 on the column C side.
As an attachment method for that purpose, for example, the aluminum alloy plate 4 is screwed and the periphery is water-cured with tape.
The reason for this is that the filler is filled later between the steel material of the side plate 1 and the aluminum alloy plate 4, but when it is mortar, the moisture of the mortar invades and no electrolytic corrosion occurs. It is for doing so.

<9>側板1と受圧体2の取り付け。
柱Cの対向する両面に側板1を仮り設置する。
そして、両側板1の間に受圧体2をボルト止めして取り付ける。
この受圧体2の固定位置は、柱Cの断面外であり、ブレースBの設置位置側である。
<9> Attachment of the side plate 1 and the pressure receiving body 2.
The side plates 1 are temporarily installed on both sides of the column C facing each other.
And the pressure receiving body 2 is bolted and attached between the side plates 1.
The fixing position of the pressure receiving body 2 is outside the cross section of the column C, and is on the installation position side of the brace B.

<10>側板の固定。
柱Cの側板1を取り付けていない他の対向面の両側に、緊張材3を配置する。
その際にはまだ緊張材3に緊張力を与えない。
<10> Fixing the side plate.
Tensile members 3 are arranged on both sides of the other facing surface to which the side plate 1 of the column C is not attached.
At that time, the tension material 3 is not given tension yet.

<11>充填材の充填。
柱Cの外面と、側板1の内面との間に充填材を充填する。
この充填材として、たとえばエポキシ樹脂系接着剤や樹脂モルタル、低発熱型無収縮モルタルを採用することができる。
<11> Filling with filler.
A filler is filled between the outer surface of the column C and the inner surface of the side plate 1.
As this filler, for example, an epoxy resin adhesive, a resin mortar, or a low heat generation type non-shrink mortar can be employed.

<12>緊張材の緊張。
充填材、たとえば低発熱型無収縮モルタルの圧縮強度が所定の値に達したことを確認したら、緊張材3を緊張する。
こうして本発明の支持体Sと柱Cを強固に一体化することができる。
<12> Tension tension.
When it is confirmed that the compressive strength of the filler, for example, the low heat generation type non-shrink mortar, has reached a predetermined value, the tension material 3 is tensioned.
Thus, the support S and the pillar C of the present invention can be firmly integrated.

<13>ブレース材の取り付け。
図3に示すように、同一の面内において、ひとつの柱Cの上端と、他の柱Cの下端など対向する位置に支持体Sを固定する。
その固定が完了したら、この係合板21のピン穴を介してブレースBやダンパーの端部を係合して取り付けて工事は完成する。
<13> Installation of brace material.
As shown in FIG. 3, in the same plane, the support S is fixed at opposing positions such as the upper end of one column C and the lower end of another column C.
When the fixing is completed, the work is completed by engaging and attaching the ends of the brace B and the damper through the pin holes of the engagement plate 21.
