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 the 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.

The reinforcing structure of the present invention will be specifically described with reference to the drawings.
FIG. 1 shows a reinforcing structure according to the present invention in which a T-shaped reinforcing member is arranged so as to span a junction between a column structure material and a base, and an auxiliary member made of a plate-shaped metal member having a Z-shaped cross section is used. An embodiment is shown. (1) is a front view, (2) is a side view, and (3) is an enlarged view of a portion indicated by a circle X in (2). FIG. 2 shows an auxiliary member having a Z-shaped cross section made of a plate-like metal member having a refracting portion that is refracted in opposite directions at both ends used in the reinforcing structure of the present invention. (1) is a side view and (2) is a perspective view. In FIG. 2, reference numerals 601 and 602 denote refraction parts, and 603 denotes a fixing hole.

図1に示すように、本発明の補強構造は、補強部材を構成する表面金属部材2のT字形状の横長部を、柱構造材12と連結する土台14に配置し、T字形状の縦長部を柱構造材12と土台14とに架け渡して補強部材を配置し、取付け用金属部材1は柱構造材12および土台14にそれぞれ取付け、T字形状の縦長部を柱構造材12に取付けた補強構造である。図1の補強構造においては、前記板状金属部材からなる断面形状がZ字状の補助部材60を用い、該断面形状Z字状の補助部材60の屈折部の一方602を土台14と基礎15との間に挿着し、他方の屈折部601が、土台14の上面側で前記補強部材の表面金属部材2のT字形状の横長部の上縁部に当接可能に配置して土台14に設置し補強部材と重合して固定してなる補強構造である。   As shown in FIG. 1, in the reinforcing structure of the present invention, the T-shaped laterally long portion of the surface metal member 2 constituting the reinforcing member is disposed on the base 14 connected to the column structural member 12, and the T-shaped vertically long The reinforcing member is arranged across the column structure material 12 and the base 14, the mounting metal member 1 is attached to the column structure material 12 and the base 14, and the T-shaped vertically long portion is attached to the column structure material 12. Reinforced structure. In the reinforcing structure of FIG. 1, an auxiliary member 60 having a Z-shaped cross section made of the plate-like metal member is used, and one of the refracting portions 602 of the auxiliary member 60 having the Z-shaped cross section is used as the base 14 and the foundation 15. The other refracting portion 601 is disposed so as to be able to contact the upper edge of the T-shaped laterally long portion of the surface metal member 2 of the reinforcing member on the upper surface side of the base 14. It is a reinforcing structure that is installed on and fixed with a reinforcing member.

本発明の補強構造において、補強部材を構成する取付け用金属部材1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。また前記補助部材60は固定穴603でスクリューネジ、釘、ネジ釘等の固定部品により土台に取付けられる。   In the reinforcing structure of the present invention, the mounting metal member 1 constituting the reinforcing member is attached to the pillar structure material and the base by a fixing part such as a screw screw, a nail, or a screw nail. The auxiliary member 60 is attached to the base by fixing parts such as a screw screw, a nail, and a screw nail through a fixing hole 603.

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/mm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/mm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/mm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/mm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.

本発明の補強構造に使用される前記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 in the reinforcing member used in the reinforcing structure of the present invention is the material and type of the energy absorber, the material of the building or the structural material of the building on which the reinforcing member of the present invention is constructed. Depending on the type and type, i.e., the wood or steel member, or the construction site, an appropriate thickness is taken into consideration, but if the thickness is too thick, the reinforcing member itself is too thick, If it is too thin, the intended purpose cannot be 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. Moreover, the width | variety of the energy absorber 3 should just be the range of 10-90% with respect to the width | variety of a column member, and is equivalent to the width | variety of a surface metal member, and 20-80% is normally employ | adopted. The width of the mounting metal member is 50 to 100% with respect to the width of the column member.

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前記断面形状がZ字状の補助部材は、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。また幅は補強部材のT字形状の横長部の長さより少なくとも左右5mm以上長いことが望ましい。あまりに長くても補助部材のもたらす効果を高めるものでなく、コストが高くなる。また屈折部間の長さは土台の厚み幅に相当する長さであり、屈折部の長さは土台に挿着する側は、少なくとも100mmで、通常100〜150mmであればよい。一方補強部材のT字形状の横長部と当接する側は、少なくともT字形状の横長部の上縁部に接し浮き上がるのを抑えるに要する長さ(出張り)があることが必要であり、前記横長部の厚みにもよるが通常4〜15mmであり、好ましくは5〜12mmである。   The auxiliary member having a Z-shaped cross section used in the reinforcing structure of the present invention is usually made of steel plate, stainless steel or spring steel, and its thickness is generally 1 to 6 mm, preferably 1 .5 to 5 mm. The width is desirably at least 5 mm longer than the length of the T-shaped laterally long portion of the reinforcing member. If the length is too long, the effect of the auxiliary member is not enhanced, and the cost is increased. Further, the length between the refracting portions is a length corresponding to the thickness width of the base, and the length of the refracting portion is at least 100 mm on the side to be inserted into the base, and is usually 100 to 150 mm. On the other hand, the side of the reinforcing member that comes into contact with the T-shaped laterally long portion needs to have at least a length (projection) required to prevent it from coming into contact with the upper edge of the T-shaped laterally long portion, Although it depends on the thickness of the horizontally long portion, it is usually 4 to 15 mm, preferably 5 to 12 mm.

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断面形状Z字状の補助部材を用い、該断面形状Z字状の補助部材の屈折部の一方を土台と基礎との間に挿着し、他方の屈折部が、土台の上面側で前記補強部材の表面金属部材のT字形状の横長部の上縁部に当接可能に配置して土台に設置してT字形状の横長部の浮き上がるのを防止するようにされた構造であるので、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 a cross-sectional Z-shaped auxiliary member made of the plate-like metal member in addition to the reinforcing member having the above-described structure, and the refracting part of the auxiliary member having the Z-shaped cross-sectional shape. One is inserted between the foundation and the foundation, and the other refracting part is arranged so as to be able to contact the upper edge of the T-shaped horizontally long part of the surface metal member of the reinforcing member on the upper surface side of the foundation. Since it is a structure that is installed on the base to prevent the T-shaped laterally long part from floating, the extension force at the joint between the column structure material and the base, tearing coupled with the reinforcing action by the reinforcing member Further, the resistance to pulling out and the like is further increased.
