Description

本発明は木造建築物又は鉄骨建造物における柱構造材と該柱構造材に連結する他の構造材との接合部に架け渡して用いられる建築物及び建造物の補強部材を使用した防振性及び耐震性に優れた建築物及び建造物の補強構造に関する。   The present invention relates to an anti-vibration property using a building and a reinforcing member for a building that are used across a junction between a column structure material in a wooden building or a steel structure and another structure material connected to the column structure material. Further, the present invention relates to a building excellent in earthquake resistance and a reinforcing structure of the building.

木造建築物及び鉄骨建造物における防振性、耐震性の必要性は近年、益々理解が深まり、その関心度も高くなっている。なお、本発明において木造建築物というときは、木造建築物或いは木造建造物を含んだ意味で用いられ、鉄骨構造建造物というときは、軽量鉄骨建築物及び重量鉄骨建造物を含んだ意味で用いられる。   In recent years, the need for anti-vibration and seismic resistance in wooden buildings and steel structures has become more and more deeply understood, and the degree of interest has increased. In the present invention, the term “wooden building” is used to include a wooden building or a wooden structure, and the term “steel structure building” is used to include a lightweight steel structure and a heavy steel structure. It is done.

従来、木造建築物及び鉄骨建造物を補強するための補強構造としては、木造軸組建築物における柱、間柱、土台、梁及び胴差等の構造材間、木造枠組壁工法建築物における角材等の構造材間において構築される筋交いやブレス構造等の補強材を架け渡した補強構造、又は鉄骨建造物における柱、梁材等の構造材間に設けられたラーメン構造やブレス構造等の補強構造が用いられ広く知られている。   Conventionally, as reinforcement structures for reinforcing wooden buildings and steel frame buildings, there are structural members such as columns, studs, foundations, beams and trunk differences in wooden framed buildings, square members in wooden framed wall construction buildings, etc. Reinforcement structure spanning reinforcements such as braces and breath structures constructed between these structural materials, or reinforcement structures such as ramen structures and breath structures provided between structural materials such as columns and beams in steel structures Is widely used.

上記のラーメン構造やブレス構造等の補強構造は、このような補強構造が存在しない構造の建築物や建造物に比べて、耐震性や防振性が向上する。建築物及び建造物を補強するための補強構造として、制震構造を用いて耐震性能をより高いものとするための補強構造が、例えば、特許文献１、特許文献２により知られている。
特許文献１、２に示された補強構造は、一方の構造材（構造材Ａ）と他の構造材（構造材Ｂ）とで形成される角部において、構造材Ａの途中から他方の構造材Ｂの途中に、バネ鋼からなる補強部材を架け渡して固定してなるものである。また特許文献２に記載の補強構造は、上記構造材Ａと構造材Ｂとバネ鋼からなる補強部材とで構成される空間部内に合成樹脂発泡体を圧縮状態で固定してなるものである。
また、例えば、特許文献３には、建築物や建造物における二つの構造材で形成された仕口に設置される補強部材であって、耐震性能の高い制震構造を有し、該仕口の変形に追従して減衰効果を発揮し、また該仕口の角度を正常な位置に復元するための復元力が発揮された補強部材および補強構造が示されている。
また、特許文献４には、土台と土台上に立設する柱とを締結する１枚の平板状金具に係止爪を設けた構造の柱脚金具を用いた補強構造が開示されている。 Reinforcing structures such as the above-mentioned ramen structure and breath structure are improved in earthquake resistance and vibration resistance as compared with buildings and structures having such a structure. As a reinforcing structure for reinforcing a building and a building, for example, Patent Document 1 and Patent Document 2 disclose a reinforcing structure for improving seismic performance using a damping structure.
The reinforcing structures shown in Patent Documents 1 and 2 are the structure of the other structure from the middle of the structural material A at the corner formed by one structural material (structural material A) and the other structural material (structural material B). In the middle of the material B, a reinforcing member made of spring steel is bridged and fixed. The reinforcing structure described in Patent Document 2 is obtained by fixing a synthetic resin foam in a compressed state in a space formed by the structural material A, the structural material B, and a reinforcing member made of spring steel.
Further, for example, Patent Document 3 is a reinforcing member installed in a joint formed of two structural materials in a building or a building, and has a seismic control structure with high seismic performance. A reinforcing member and a reinforcing structure are shown which exhibit a damping effect following the deformation and exhibit a restoring force for restoring the angle of the joint to a normal position.
Further, Patent Document 4 discloses a reinforcing structure using a column base metal fitting having a structure in which a locking claw is provided on a single plate-like metal fitting for fastening a base and a column standing on the base.

特許文献１及び特許文献２に示されたような従来の補強構造は、一方の構造材と他方の構造材（例えば、柱と梁や桁あるいは柱と土台）との間に形成される角部において、一方の構造材と他方の構造材との間に補強部材を架け渡して補強する方式である。このような補強構造では、柱の曲げ歪が大きくなると接合部分が離れ補強作用が十分に発揮されない。また木造建築物の場合、木部自体の強度が固定部材の強度に負け木部が破壊する虞がある等、柱の曲げ強度や固定部の強度等の性能に大きく影響され易いという問題がある。   The conventional reinforcing structure as shown in Patent Document 1 and Patent Document 2 is a corner portion formed between one structural material and the other structural material (for example, a column and a beam, a girder, or a column and a base). In this method, a reinforcing member is bridged between one structural material and the other structural material for reinforcement. In such a reinforcing structure, when the bending strain of the column is increased, the joint portion is separated and the reinforcing action is not sufficiently exhibited. In the case of a wooden building, there is a problem that the strength of the wooden part itself is likely to be greatly affected by the performance such as the bending strength of the column and the strength of the fixing part, such as the possibility that the wooden part may be damaged by the strength of the fixing member. .

Tension of the joint between the column structure material and other structural materials (horizontal materials such as beams and girders or foundations) without being greatly affected by the direct mounting, performance such as the bending strength of the column structure material itself and the strength of the fixed part The present invention has proposed a reinforcing member and a reinforcing structure using the reinforcing member that can absorb and attenuate shearing force and elongation force and can absorb bending strain.

なお、本発明において「柱構造材及び土台」を総称して「構造材」と呼称する。また「柱構造材」を「柱部材」ということがある。   In the present invention, “column structure material and foundation” are collectively referred to as “structure material”. Further, the “column structure material” is sometimes referred to as a “column member”.

本発明の補強構造に使用される補強部材は、建築物及び建造物の構造材への取付け用金属部材（以下、単に「取付け用金属部材」ということがある）、エネルギー吸収体及び表面金属部材とで構成されており、前記エネルギー吸収体が前記取付け用金属部材と前記表面金属部材との間に連続して配置されて挟持され、前記金属部材と相互に接合されて一体に構成されている構造からなる。   The reinforcing member used in the reinforcing structure of the present invention is a metal member for mounting on a building and a structural material of a building (hereinafter, simply referred to as “mounting metal member”), an energy absorber, and a surface metal member.

前記構造からなる本発明における補強部材は、前記取付け用金属部材と表面金属部材との間に挟持されたエネルギー吸収体が、建築物及び建造物の構造材に対して外部から加わる引張り剪断力や伸縮力（引張／圧縮及び剪断による複合力）等のエネルギー（変形エネルギー）を吸収し、減衰させ構造体の変形を抑制することにより防振性及び耐震性に優れた補強構造が発現される。   The reinforcing member according to the present invention having the structure described above includes a tensile shear force applied from the outside to the building and the structural material of the building by the energy absorber sandwiched between the mounting metal member and the surface metal member.

FIG. 1 shows a belt-shaped reinforcing member placed over a joint between a column structure material and a base, and an auxiliary member made of a plate-like metal member is disposed between the base and the foundation to form a set with the reinforcing member. The embodiment of the combined reinforcement structure of this invention is shown.

Indicates. In FIG. 1, reference numeral 50 denotes an auxiliary member made of a plate-like metal member. Reference numeral 12 denotes a column structure material, 14 denotes a base, and 15 denotes a foundation.

図１に示すように、本発明の補強構造は、建築物及び建造物の柱構造材への取付け用金属部材１および表面金属部材２が少なくとも２個の複数に分割された補強部材を用いて、前記補強部材を構成する分割された表面金属部材２の一つは、柱構造材１２と土台１４との接合部に架け渡して補強部材を配置し、分割された他方の表面金属部材２は固定部２１で柱構造材１２に固定されている。分割された取付け用金属部材１は、連続したエネルギー吸収体３を挟持した状態でそれぞれ土台１４、柱構造材１２に取付けられている。土台１４と基礎１５との間には板状金属部材からなる補助部材５０を配し、該補助部材５０の一方を基礎に固定し、他方を、補強部材を構成する表面金属部材２と連結して構成された補強構造である。上記は取付け用金属部材および表面金属部材が２つに分割された例を示したが、これらの金属部材は２つに分割されたものに限らず、３個、またはそれ以上に分割されていても差し支えないが、多分割することによる利点は特にない。   As shown in FIG. 1, the reinforcing structure of the present invention uses a reinforcing member in which a metal member 1 for attachment to a building and a pillar structure material of a building and a surface metal member 2 are divided into at least two pieces. One of the divided surface metal members 2 constituting the reinforcing member is arranged over the joint portion between the column structure material 12 and the base 14 and the reinforcing member is arranged, and the other divided surface metal member 2 is It is fixed to the column structure member 12 by a fixing portion 21. The divided mounting metal members 1 are respectively attached to the base 14 and the column structure member 12 with the continuous energy absorber 3 sandwiched therebetween. An auxiliary member 50 made of a plate-like metal member is arranged between the base 14 and the foundation 15, one of the auxiliary members 50 is fixed to the foundation, and the other is connected to the surface metal member 2 constituting the reinforcing member. This is a reinforced structure. The above shows an example in which the mounting metal member and the surface metal member are divided into two. However, these metal members are not limited to two, but are divided into three or more. However, there is no particular advantage of multi-segmentation.

上記の柱構造材と土台との接合部に架け渡された表面金属部材２と板状金属部材からなる補助部材５０との連結部２２はボルトナット７により連結されている。また板状金属部材からなる補助部材５０の基礎１５との固定はアンカーボルト５１等により固定されている。また、補強部材を構成する取付け用金属部材の柱構造材および土台への取付けは、スクリューネジ、釘、ネジ釘等の固定部品により取付けられる。   A connecting portion 22 between the surface metal member 2 and the auxiliary member 50 made of a plate-like metal member, which is spanned over the joint portion between the column structure material and the base, is connected by a bolt nut 7. Further, the auxiliary member 50 made of a plate-like metal member is fixed to the base 15 by anchor bolts 51 or the like. Further, the mounting metal member constituting the reinforcing member is attached to the column structure material and the base by a fixing part such as a screw screw, a nail or a screw nail.

本発明の補強構造に使用される前記補強部材を構成するエネルギー吸収体３は、外部からの応力により構造材間に加わる引張剪断力及び伸縮力（引張／圧縮及び剪断による複合力）を吸収し、減衰し元の形状に復元させる機能を有する。このような観点からエネルギー吸収体３は、等価減衰定数（Ｈｅｑ）が１０〜６０％、剪断弾性係数（Ｇ）が０．０５〜２．０Ｎ／ｍｍ２を示すものが使用される。等価減衰定数（Ｈｅｑ）が１０％未満ではエネルギー吸収量が小さく好ましくない。また剪断弾性係数（Ｇ）が０．０５Ｎ／ｍｍ２未満のものは、柔らか過ぎてエネルギー吸収量が小さく、２．０Ｎ／ｍｍ２を超えるものでは、剛性が高すぎエネルギー吸収量が小さく、引張剪断力や伸縮力によるエネルギーを十分に吸収し、かつ変形に対して抗することができず所期の目的が得られない。実用的な観点から等価減衰定数（Ｈｅｑ）は１０〜４０％が好ましい。また、剪断弾性係数（Ｇ）は好ましくは、０．１〜１．２Ｎ／ｍｍ２である。
この様な特性を示し本発明に使用される補強部材に使用し得るエネルギー吸収体としては、例えば、高減衰性ゴムや粘弾性熱可塑性樹脂が挙げられ、粘弾性熱可塑性樹脂は、例えば、硬質ウレタン樹脂、シリコン樹脂等が挙げられる。これらのうち、特に高減衰性ゴムが好適である。 The energy absorber 3 constituting the reinforcing member used in the reinforcing structure of the present invention absorbs the tensile shear force and expansion / contraction force (combined force by tension / compression and shear) applied between the structural members due to external stress. , Has a function to attenuate and restore the original shape. From such a viewpoint, the energy absorber 3 having an equivalent damping constant (Heq) of 10 to 60% and a shear elastic modulus (G) of 0.05 to 2.0 N / mm 2 is used. If the equivalent attenuation constant (Heq) is less than 10%, the amount of energy absorption is small, which is not preferable. A material having a shear elastic modulus (G) of less than 0.05 N / mm 2 is too soft and has a small energy absorption amount, and a material having a shear elastic modulus (G) of more than 2.0 N / mm 2 has a too high rigidity and a small amount of energy absorption. Energy due to shearing force and stretching force is sufficiently absorbed, and the intended purpose cannot be obtained because it cannot resist deformation. From a practical viewpoint, the equivalent attenuation constant (Heq) is preferably 10 to 40%. The shear elastic modulus (G) is preferably 0.1 to 1.2 N / mm 2 .
Examples of the energy absorber that exhibits such characteristics and can be used for the reinforcing member used in the present invention include high-damping rubber and viscoelastic thermoplastic resin, and viscoelastic thermoplastic resin is, for example, hard Examples thereof include urethane resin and silicon resin. Of these, high-damping rubber is particularly preferable.

本発明に使用される補強部材に用いられるエネルギー吸収体３の厚みは、エネルギー吸収体の材質や種類、本発明の補強部材が施工される建築物や建造物の構造材の材質や種類、即ち木質部材か鉄骨部材か、また施工される個所などにより異なり、これらを勘案して適宜の厚みが採用されるが、厚みが余りにも厚い場合には補強部材自体が厚くなりすぎ、また薄すぎる場合には所期の目的が達成されない。エネルギー吸収体が高減衰性ゴムの場合、通常１〜５０ｍｍ、好ましくは３〜３０ｍｍ、さらに好ましくは５〜２０ｍｍである。エネルギー吸収体の厚みが１ｍｍ未満の場合は変形に対するエネルギーを十分に吸収することができず、一方５０ｍｍを超えるような場合には、補強部材全体が厚くなり、またコスト高となる。また、エネルギー吸収体３の幅は表面金属部材の幅と同等で柱部材の幅に対し１０〜９０％の範囲であればよく、通常２０〜８０％が採用される。また前記取付け用金属部材の幅は柱部材の幅に対し５０〜１００％である。   The thickness of the energy absorber 3 used for the reinforcing member used in the present invention is the material and type of the energy absorber, and the material and type of the building material or the structural material of the building on which the reinforcing member of the present invention is constructed, that is, It depends on whether it is a wooden member or steel member, or the location where it is constructed, and an appropriate thickness is taken into account.However, if the thickness is too thick, the reinforcing member itself is too thick or too thin. The intended purpose is not achieved. When the energy absorber is a highly attenuating rubber, it is usually 1 to 50 mm, preferably 3 to 30 mm, and more preferably 5 to 20 mm. When the thickness of the energy absorber is less than 1 mm, energy for deformation cannot be sufficiently absorbed. On the other hand, when the thickness exceeds 50 mm, the entire reinforcing member becomes thick and the cost increases.

本発明の補強構造に使用される補強部材における取付け用金属部材と表面金属部材間に配置されるエネルギー吸収体を、取付け用金属部材と表面金属部材とで挟持し接合させて一体化するには、例えば、取付け用金属部材及び表面金属部材のエネルギー吸収体と接合される面を、接着性能を高めるためにブラスト研磨等を行い、両方の金属部材のエネルギー吸収体との接合面に、金属部材とエネルギー吸収体の両者に接着性を有する接着材、例えば、エポキシ系接着剤、ゴム系接着剤、フェノール樹脂／ゴム系接着材を塗布し、エネルギー吸収体を両金属部材間に挟持した状態で加圧下に加熱し加硫処理を行う等により取付け用金属部材及び表面金属部材とエネルギー吸収体とが一体的に強固に接合された本発明に係る補強部材を得ることができる。   To integrate the energy absorber disposed between the mounting metal member and the surface metal member in the reinforcing member used in the reinforcing structure of the present invention by sandwiching and joining the mounting metal member and the surface metal member For example, the surface of the metal member for attachment and the surface of the metal member to be bonded to the energy absorber are subjected to blast polishing or the like in order to enhance the adhesion performance, and the metal member is bonded to the surface of the energy absorber of both metal members. In the state where an adhesive having adhesiveness to both the energy absorber, for example, an epoxy adhesive, a rubber adhesive, a phenol resin / rubber adhesive is applied, and the energy absorber is sandwiched between both metal members It is possible to obtain the reinforcing member according to the present invention in which the mounting metal member and the surface metal member and the energy absorber are integrally and firmly joined by heating under pressure and vulcanizing. Kill.

本発明に使用される補強部材を構成する取付け用金属部材及び表面金属部材の厚みは、これら金属部材の材質や本発明の補強部材が施工される建築物や建造物の構造材の材質や種類、即ち対象とする建築物や建造物が木質系か鉄骨系か、また施工される個所などにより異なり一概には決められないが、取付け用金属部材は通常１〜６ｍｍの範囲のものが使用され、好ましくは１．５〜５ｍｍである。また表面金属部材は２〜１２ｍｍの範囲のものが使用され、好ましくは２〜１０ｍｍで、より好ましくは１．５〜５ｍｍある。取付け用金属部材と表面金属部材との厚みは同一であることが望ましいが必ずしも同一である必要はない。木造建築物および建造物の場合には、上記両金属部材は、一般的には２〜３．５ｍｍの厚さのものが用いられる。これらの金属部材の厚みが薄い場合には、変形に対する強度が不十分となる虞があり、厚みが厚い場合は、補強部材の変形に対する強度の点では差し支えないが、全体の重量が大きくなり、例えば、木造建築物および建造物の柱部材や土台等の構造材への保持に対して構造材の固定部が耐えられなくなる虞がある。また全体のコストが高くなる。
これらの金属部材は通常鋼板やステンレスが使用され、取付け用金属部材と表面金属部材とは同じであっても異なってもよい。 The thickness of the metal member for mounting and the surface metal member constituting the reinforcing member used in the present invention is the material and type of the material of these metal members and the building or the structural material of the building where the reinforcing member of the present invention is constructed. In other words, it depends on whether the target building or building is a wood or steel frame, and the construction site, etc., but it can not be determined unconditionally, but metal members for mounting are usually in the range of 1 to 6 mm. The thickness is preferably 1.5 to 5 mm. The surface metal member is used in the range of 2 to 12 mm, preferably 2 to 10 mm, more preferably 1.5 to 5 mm. Although it is desirable that the mounting metal member and the surface metal member have the same thickness, they need not necessarily be the same. In the case of a wooden building and a building, the two metal members generally have a thickness of 2 to 3.5 mm. If the thickness of these metal members is thin, the strength against deformation may be insufficient.If the thickness is thick, there is no problem in terms of strength against deformation of the reinforcing member, but the overall weight increases. For example, there is a possibility that the fixed portion of the structural material cannot withstand holding to a structural material such as a wooden building and a pillar member or foundation of the building. In addition, the overall cost increases.
These metal members are usually steel plates or stainless steel, and the mounting metal member and the surface metal member may be the same or different.

本発明の補強構造に使用される板状金属部材からなる補助部材は、通常鋼板やステンレスあるいはバネ鋼が使用され、その厚みは一般的には、１〜６ｍｍであり、好ましくは、１．５〜５ｍｍである。また幅は補強部材を構成する取付け用金属部材あるいは表面金属部材と同等でよい。   The auxiliary member made of a plate-like metal member used in the reinforcing structure of the present invention is usually a steel plate, stainless steel or spring steel, and its thickness is generally 1 to 6 mm, preferably 1.5. ~ 5 mm. The width may be the same as that of the mounting metal member or the surface metal member constituting the reinforcing member.

本発明の補強部材に使用される前記補強部材は、取付け用金属部材と表面金属部材との金属部材間に高減衰ゴムのようなエネルギー吸収体が挟持されて一体的に構成されているので、外部応力の減衰効果が大きい。該補強部材を建築物又は建造物の柱構造材と土台との接合部に架け渡して設置した補強構造は、このような補強部材を使用しない場合に比べ、構造部材に加わる引張り剪断力の３０〜４０％の減衰効果が得られる。また地震等による応答加速度の変形は４０〜５０％の減衰効果が得られる。
そのうえ、本発明における補強構造は、前記構造からなる補強部材に加えて前記の板状金属部材からなる補助部材を使用し、該補助部材を土台および基礎部分に配置して、一方を基礎に固定し他方を前記表面金属部材と連結し板状金属部材からなる補助部材と補強部材とを組合わせた構造であるので、補強部材による補強作用と相俟って柱構造材と土台との接合部における伸長力、引き裂き、引抜き等に対する耐力が更に高められている。 Since the reinforcing member used for the reinforcing member of the present invention is integrally configured with an energy absorber such as a high damping rubber sandwiched between the metal members of the mounting metal member and the surface metal member, The attenuation effect of external stress is large. The reinforcing structure in which the reinforcing member is installed across the joint between the building or the pillar structure material of the building and the base has a tensile shear force of 30 applied to the structural member as compared with the case where such a reinforcing member is not used. A damping effect of ~ 40% is obtained. Moreover, the deformation of the response acceleration due to an earthquake or the like can obtain a damping effect of 40 to 50%.
In addition, the reinforcing structure in the present invention uses the auxiliary member made of the plate-like metal member in addition to the reinforcing member made of the structure, and arranges the auxiliary member on the base and the base portion, and fixes one to the foundation. However, since the other is connected to the surface metal member and the auxiliary member made of the plate-like metal member and the reinforcing member are combined, the joint portion between the column structure material and the base is combined with the reinforcing action by the reinforcing member. The strength against elongation, tearing, pulling, etc. is further increased.
