Description

この発明は、建造物の耐震補強構造に係り、特に地震時等の振動で枠体が急激に倒壊するのを回避する建造物の耐震補強構造に関するものである。 The present invention relates to a seismic reinforcing structure for a building, and more particularly to a seismic reinforcing structure for a building that prevents a frame body from abruptly collapsing due to vibration during an earthquake or the like.

先年、関西・四国方面において大規模な地震が発生し、この震災状況が異常に大きかったことから、地震に対する心構えが改善されている。 Last year, a large-scale earthquake occurred in the Kansai and Shikoku areas, and the situation of the earthquake was unusually large.

特に、木造家屋である一般住宅や高層ビル等における建造物の耐震構造に力が入れられ、その中でも、一般住宅においては、新築時に耐震構造とするのみでなく、既設建造物の改築時に耐震構造を施す等の方策が見られている。 In particular, emphasis is put on the earthquake-resistant structure of buildings in ordinary houses and high-rise buildings that are wooden houses. Among them, earthquake-resistant structures are not only made for ordinary houses when they are newly built, but also when existing buildings are renovated. Measures such as applying are seen.

ところで、従来、図１４に示す如く、特に一般住宅の建造物１０２においては、地盤（図示せず）にコンクリートによる基礎１０４を敷設し、この基礎１０４上には枠体１０６を立設している。この枠体１０６は、基礎１０４上に載置された土台１０８と、この土台１０８に所定間隔で立設された複数の柱１１０と、土台１０８に対して平行で複数の柱１１０の上部に設けられた桁１１２と、隣接する柱１１０・１１０の間に配設された間柱１１４とにより構築されている。また、図示しないが、各柱１１０・１１０の間には、壁体を構成するように、内壁材と外壁材とを設けている。 Conventionally, as shown in FIG. 14, in particular, in a general residential building 102, a concrete foundation 104 is laid on the ground (not shown), and a frame body 106 is erected on the foundation 104. . The frame body 106 is provided on a base 108 placed on the foundation 104, a plurality of pillars 110 erected on the base 108 at a predetermined interval, and on top of the pillars 110 parallel to the base 108. Spar 112 and an inter-column 114 arranged between adjacent columns 110 and 110. Moreover, although not shown in figure, the inner wall material and the outer wall material are provided between each pillar 110 * 110 so that a wall body may be comprised.

しかしながら、このような建造物１０２の構造にあっては、つまり、枠体１０６の隣接する柱１１０・１１０の間に間柱１１４を配設した構造においては、地震時等に、例えば、左右方向の振動が発生すると、図１４の破線で示す如く、各柱１１０及び間柱１１４が変形し易く、枠体１０６全体が急激に倒壊してしまう。 However, in such a structure of the building 102, that is, in a structure in which the inter-columns 114 are disposed between the adjacent columns 110 and 110 of the frame body 106, for example, in the horizontal direction in the event of an earthquake, for example. When vibration occurs, as shown by the broken lines in FIG. 14, the columns 110 and the intermediate columns 114 are easily deformed, and the entire frame 106 collapses rapidly.

このような不具合を解消するために、枠体の隣接する柱の間において、斜め状態に木製の筋交いを設けた構造がある。 In order to solve such a problem, there is a structure in which wooden braces are provided in an oblique state between adjacent columns of the frame.

ところが、このような筋交いにおける耐震構造においては、新築時には対応し得るものの、改築時には、壁体の表面に筋交いを取り付けることができなかったり、あるいは、小スペースでの作業が困難なために、壁体の全域を取り除き、その後に施工を行う必要があり、その作業性が面倒であるという不都合があった。 However, in such a seismic structure for bracing, although it can be accommodated at the time of new construction, it cannot be attached to the surface of the wall at the time of reconstruction, or work in a small space is difficult, so It was necessary to remove the entire body and then perform the construction, and there was an inconvenience that the workability was troublesome.

この発明は、基礎上に載置された土台と、この土台に所定間隔で立設された複数の柱と、前記土台に対して平行で前記複数の柱の上部に設けられた桁と、隣接する前記柱の間に配設された間柱とにより構築された枠体を有する建造物において、少なくとも隣接する前記柱の上部に索条支持具を夫々取り付け、これら索条支持具に索条を支持させるとともに、この索条が緊張するように前記索条の両端部を前記土台に固定した耐震補強手段を設け、前記枠体が傾斜したときに前記索条と前記索条支持具との間に摩擦を発生させる摩擦発生手段を設けたことを特徴とする。 The present invention relates to a base placed on a foundation, a plurality of pillars erected on the foundation at a predetermined interval, a girder provided on top of the plurality of pillars in parallel to the foundation, and adjacent to the base In a building having a frame constructed by the inter-columns arranged between the pillars to be attached, a rope support is attached to each upper part of at least the adjacent pillars, and the ropes are supported by these rope supports. And providing seismic reinforcement means for fixing both ends of the rope to the base so that the rope is tensioned, and when the frame body is inclined, the rope is placed between the rope and the rope support. Friction generating means for generating friction is provided.

この発明の建造物の耐震補強構造は、地震時等に、振動によって枠体が傾斜したときに、耐震補強手段の索条と索条支持具との間に、摩擦発生手段によって摩擦を発生させることから、索条に大きな張力を発生させ、これにより、枠体の変形を抑制し、枠体全体が急激に倒壊するのを回避することができ、また、新築時や改築時に、耐震補強手段や摩擦発生手段を、枠体内の小スペースに容易に設置することが可能であり、既存の建造物にも容易に設置させて汎用性を高くすることができ、さらに、耐震補強手段や摩擦発生手段の設置の作業性を容易とし、しかも、構成が簡単で、廉価とすることができる。 The seismic reinforcement structure of a building according to the present invention generates friction between the rope of the earthquake-proof reinforcement means and the rope support by the friction generating means when the frame is inclined by vibration during an earthquake or the like. Therefore, it is possible to generate a large tension on the rope, thereby suppressing the deformation of the frame body and avoiding the collapse of the entire frame body. And friction generating means can be easily installed in a small space inside the frame, and can be easily installed in existing buildings to increase versatility. The installation workability of the means is facilitated, and the configuration is simple and inexpensive.

地震時等において建造物の枠体が急激に倒壊するのを回避する目的を、耐震補強手段の索条と索条支持具との間に摩擦を発生させて実現するものである。
以下図面に基づいてこの発明の実施例を詳細且つ具体的に説明する。 The purpose of avoiding sudden collapse of the building frame during an earthquake or the like is realized by generating friction between the rope of the seismic reinforcement means and the rope support.

この枠体６には、建造物２を耐震補強するように、耐震補強手段１８が設けられる。 The frame 6 is provided with earthquake-proof reinforcing means 18 so as to provide earthquake-proof reinforcement for the building 2.

この耐震補強手段１８は、隣接する第１柱１０−１・第２柱１０−２の上部に、例えば、滑車（プーリー）等からなる第１索条支持具２０−１・第２索条支持具２０−２の第１軸２２−１・第２軸２２−２を、第１保持部材２４−１・第２保持部材２４−２によって夫々取り付けるとともに、間柱１４の取付用切除部２６には、前記第１索条支持具２０−１・第２索条支持具２０−２と略同一の高さで、同様に、滑車等からなる第３索条支持具２０−３の第３軸２２−３を、第３保持部材２４−３によって取り付け、そして、これら第１〜第３索条支持具２０−１〜２０−３には、例えば、ワイヤロープ等からなる索条２８を支持させるように巻き掛けて設け、さらに、この索条２８が緊張するように、例えば、索条２８の一方の一端部２８Ａを、第２索条支持具２０−２の下方で、土台４と第２柱１０−２の下部との接合部位で第２固定具３０−２によって固定するとともに、索条２８の他方の他端部２８Ｂを、第１索条支持具２０−１の下方で、土台４と第１柱１０−１の下部との接合部位で第１固定具３０−１によって固定して構成される。前記索条支持具２０は、軸２２に対して回転可能であるが、軸２２に対して抵抗によって回転しにくくなるように、例えば、軸２２の外面と索条支持具２０の軸孔内面との間で滑り摩擦を生じさせる所要の回転抑制手段（図示せず）によって軸２２に取り付けられている。 This seismic reinforcement means 18 is provided on the upper part of the adjacent first pillar 10-1 and second pillar 10-2, for example, a first rope support 20-1 and a second rope support made of a pulley (pulley) or the like.

The third shaft 22 of the third rope support 20-3, which is substantially the same height as the first rope support 20-1 and the second rope support 20-2, and is made of a pulley or the like. -3 is attached by the third holding member 24-3, and the first to third rope support tools 20-1 to 20-3 are supported by the rope 28 made of, for example, a wire rope. For example, one end portion 28 of the rope 28 is arranged so that the rope 28 is tensioned. Is fixed by the second fixing tool 30-2 at the junction between the base 4 and the lower part of the second pillar 10-2 below the second rope support 20-2, and the other of the rope 28 The end portion 28B is configured to be fixed by the first fixing tool 30-1 below the first rope support tool 20-1 at the joint portion between the base 4 and the lower portion of the first pillar 10-1. For example, the outer surface of the shaft 22 and the inner surface of the shaft hole of the cable support 20 are arranged so that the cable support 20 can rotate with respect to the shaft 22 but is less likely to rotate with resistance to the shaft 22. Is attached to the shaft 22 by required rotation restraining means (not shown) that generates sliding friction between them.

つまり、索条２８は、一端部２８Ａが第２索条支持具２０−２の下方の第２固定具３０−２に固定され、そして、第１索条支持具２０−１の上側に巻き掛けられるとともに、第３索条支持具２０−３では下側に巻き掛けられ、さらに、第２索条支持具２０−２の上側に巻き掛けられ、さらに、他端部２８Ｂが第１索条支持具２０−１の下方の第１固定具３０−１に固定され、しかも、一端部２８Ａ側と他端部２８Ｂ側とでは、間柱１４の挿通用切除部３２で交差して配設されている。 That is, the one end 28A of the rope 28 is fixed to the second fixing tool 30-2 below the second rope support 20-2, and is wound around the upper side of the first rope support 20-1. At the same time, the third rope support 20-3 is wound downward, and further wound around the second rope support 20-2, and the other end 28B is supported by the first rope support. The first fixing tool 30-1 below the tool 20-1 is fixed, and the one end portion 28A side and the other end portion 28B side are arranged so as to intersect with each other at the insertion cutting section 32 of the stud 14. .

また、枠体６には、該枠体６が傾斜したときに、索条２８と第１〜第３索条支持具２０−１〜２０−３との間に摩擦を発生させる摩擦発生手段３４が設けられる。 The frame 6 has a friction generating means 34 for generating friction between the cable 28 and the first to third cable supports 20-1 to 20-3 when the frame 6 is inclined. Is provided.

この摩擦発生手段３４は、この第１実施例において、例えば、図２に示す如く、第１索条支持具２０−１・第２索条支持具２０−２を枠体６の一側面６Ａから所定の距離Ｌ１の位置に配設するとともに、第３索条支持具２０−３を枠体６の他側面６Ｂから所定の距離Ｌ２の位置に配設し、平面視で、第１索条支持具２０−１・第２索条支持具２０−２の位置に対して第３索条支持具２０−３の巻き掛けた位置から距離Ｄ１だけ枠体６の両側面方向Ｘにずらし、さらに、索条２８を、第１索条支持具２０−１・第２索条支持具２０−２の上側に巻き掛ける一方、第３索条支持具２０−３では下側に巻き掛け、枠体６が傾斜したときに、索条２８と第１〜第３索条支持具２０−１〜２０−３との間に、抵抗力により、摩擦を発生させ、枠体６の傾斜に応じて、索条２８の引張力を大きくし、枠体６の変形を抑制し、枠体６が急激に傾斜して倒壊するのを回避させる。 In the first embodiment, for example, as shown in FIG. 2, the friction generating means 34 is configured to move the first rope support 20-1 and the second rope support 20-2 from one side surface 6 A of the frame body 6. The third strip support 20-3 is disposed at a predetermined distance L2 from the other side surface 6B of the frame body 6 and is disposed at a predetermined distance L1. Shifted in the direction X on both sides of the frame 6 by a distance D1 from the position where the third rope support 20-3 is wound with respect to the position of the tool 20-1 and the second rope support 20-2, While the rope 28 is wound on the upper side of the first rope support 20-1 and the second rope support 20-2, the third rope support 20-3 is wound on the lower side, and the frame 6 When the heel is inclined, friction is generated between the rope 28 and the first to third rope supports 20-1 to 20-3 by the resistance force, and the frame 6 is inclined. Depending on, to increase the tensile force of the rope 28, to suppress the deformation of the frame 6, frame 6 is prevented from collapsing rapidly tilted.

また、索条２８には、緊張力調整手段３６が設けられる。 In addition, the rope 28 is provided with tension adjusting means 36.

この緊張力調整手段３６は、例えば、第２索条支持具２０−２と間柱１４の挿通用切除部３２との間の索条２８の途中に、索条２８の張力を調整可能なターンバックル３８を介設するとともに、間柱１４の挿通用切除部３２と他端部２８Ｂとの間の索条２８の途中には、索条２８に付勢力としての収縮力を付与するスプリング４０を介設している。 This tension adjusting means 36 is, for example, a turnbuckle that can adjust the tension of the rope 28 in the middle of the rope 28 between the second rope support 20-2 and the insertion cutting part 32 of the intermediary column 14. 38, and a spring 40 for applying a contracting force as an urging force to the rope 28 in the middle of the rope 28 between the insertion cutting portion 32 of the stud 14 and the other end 28B. is doing.

次に、この第１実施例の作用を説明する。 Next, the operation of the first embodiment will be described.

建造物２の枠体６内に形成される空間１６に耐震補強手段１８を構築する際には、空間１６の右下側で索条２８の一端部２８Ａを第２固定具３０−２によって空間部４の右下部の土台２に固定し、そして、この索条２８を空間１４の中間部位に位置する間柱１４の挿通用切除部３２を通過させた後に、空間１４の左上部の第１索条支持具２０−１の上側に巻き掛ける。 When constructing the seismic reinforcement means 18 in the space 16 formed in the frame 6 of the building 2, the one end 28 A of the rope 28 is spaced by the second fixture 30-2 on the lower right side of the space 16. After fixing the rope 28 to the base 2 in the lower right part of the section 4 and passing the insertion cut section 32 of the stud 14 located at the intermediate portion of the space 14, the first rope in the upper left portion of the space 14. It is wound on the upper side of the strip support 20-1.

さらに、索条２８を、空間１４の左上部の第１索条支持具２０−１から中央側の間柱１４の第３索条支持具２０−３の下側に巻き掛け、さらに、空間１４の右上部の第２索条支持具２０−２の上側に巻き掛け、そして、他端部２８Ｂを、挿通用切除部３２を通過させた後、第１固定具３０−１によって空間部４の左下部の土台２に固定する。 Further, the cord 28 is wound from the first cord support 20-1 at the upper left part of the space 14 to the lower side of the third cord support 20-3 of the middle pillar 14, The upper part of the second ridge support tool 20-2 in the upper right part is wound on the upper side, and the other end part 28B is passed through the insertion cutting part 32, and then the lower left part of the space part 4 by the first fixture 30-1. Fix to the base 2 of the department.

そして、索条２８の張力を、ターンバックル３８によって調整すると、スプリング４０の収縮力も加わって、索条２８には、適正な緊張力が付与される。 When the tension of the rope 28 is adjusted by the turnbuckle 38, the contraction force of the spring 40 is also applied, and an appropriate tension force is applied to the rope 28.

また、経年変化等により索条２８に弛みが生じようとした場合には、スプリング４０の収縮力によってその索条２８の弛みが自動的に回避される。 Further, when the slack is about to occur due to secular change or the like, the slack of the streak 28 is automatically avoided by the contraction force of the spring 40.

そして、地震時等に、振動によって枠体６が傾斜したときには、索条支持具２０が軸２２に対して重く回転するように取り付けられ、また、摩擦発生手段３４により、索条２８と第１〜第３索条支持具２０−１〜２０−３との間に、抵抗力により、摩擦を発生させることから、枠体６の傾斜に応じて、索条２８の引張力が大きくなり、枠体６の変形が抑制され、枠体６が急激に傾斜して倒壊するのを回避する。 When the frame body 6 is tilted by vibration during an earthquake or the like, the rope support 20 is attached so as to rotate heavy with respect to the shaft 22, and the friction generating means 34 and the rope 28 and the first are attached. Since friction is generated between the third rope support tools 20-1 to 20-3 by a resistance force, the tensile force of the rope 28 increases according to the inclination of the frame body 6, and the frame The deformation of the body 6 is suppressed, and the frame body 6 is prevented from tilting and collapsing.

この結果、枠体６が傾斜したときに、耐震補強手段１８の索条２８と索条支持具２０との間に摩擦発生手段３４によって摩擦を発生させることから、枠体６全体が急激に倒壊するのを回避することができる。 As a result, when the frame 6 is inclined, friction is generated by the friction generating means 34 between the rope 28 of the earthquake-proof reinforcing means 18 and the rope support 20, so that the entire frame 6 collapses suddenly. Can be avoided.

また、新築時や改築時に、耐震補強手段１８や摩擦発生手段３４を枠体６の空間１６内の小スペースに容易に設置することが可能であり、既存の建造物にも容易に設置させて汎用性を高くすることができ、さらに、耐震補強手段１８や摩擦発生手段３４の設置の作業性を容易とし、しかも、構成が簡単で、廉価とすることができる。 In addition, the seismic reinforcement means 18 and the friction generating means 34 can be easily installed in a small space in the space 16 of the frame 6 at the time of new construction or reconstruction, and can be easily installed in existing buildings. The versatility can be increased, the workability of installing the earthquake-proof reinforcing means 18 and the friction generating means 34 can be facilitated, and the configuration is simple and inexpensive.

更に、耐震補強手段１８の索条支持具２０を滑車とすることにより、索条２８の取り回し等が容易となり、その作業性を向上することができる。 Furthermore, by using the rope support 20 of the seismic reinforcement means 18 as a pulley, it is possible to easily handle the rope 28 and improve its workability.
