本発明は、 地震、 台風等により木造家屋に強度の振動が負荷されても崩 壊しないように、 土台、 柱、 梁、 桁等の建築構造材の接合部に取付けて補 強することを目的とする耐震補強金具に関する。 背景技術  An object of the present invention is to attach and reinforce a joint of a building structural material such as a base, a column, a beam, and a girder so that the wooden house does not collapse even when a strong vibration is applied to the wooden house due to an earthquake, a typhoon, or the like. It relates to the seismic reinforcement metal fittings. Background art
従来、 木造建築物の構造材の接合部を補強する方法としては、 筋かいや 火打梁を設けたり、 かすがい、 L型金具を取付けたり等、 種々の方法が採 用されている。  Conventionally, various methods have been used to reinforce the joints of structural members of wooden buildings, such as providing braces and fire beams, scoring, attaching L-shaped fittings, and the like.
しかし、 上記の如き方法では、 地震、 台風等により強度の振動が負荷さ れた場合の補強効果は十分ではなく、 接合部で構造材が離反したり、 破損 したりして、 木造建築物がその接合部において破壊したり、 酷い場合には 倒壌してしまう虞れもあった。  However, the above methods do not provide sufficient reinforcement when strong vibration is applied due to an earthquake, typhoon, etc., and the structural material is separated or damaged at the joints, resulting in a wooden building. There was a risk that the joint would break down or, in severe cases, collapse.
そこで、 地震、 台風等による強度の振動にも十分耐え得るものとして、 図 5に斜視図で示すような補強金具 4 1が考案され、 使用されている。 この補強金具 4 1は、 高張力鋼よりなる板材を L形に折曲すると共に、 両片部 4 2 a , 4 2 bの中間部に内側に折曲した折曲膨出部 4 3 a , 4 3 bを形成した L形基材 4 2を設け、 この L形基材 4 2の折曲角部 4 2 cに 高張力鋼よりなる扳材を折曲した補強部材 4 4を溶接により固着し、 上記 L形基材 4 2の数ケ所に吸震ゴム等よりなる緩衝部材 4 5を係止したもの であな。  Therefore, a reinforcing bracket 41 as shown in a perspective view in FIG. 5 has been devised and used as a device capable of sufficiently withstanding a strong vibration due to an earthquake, a typhoon, or the like. The reinforcing bracket 41 is formed by bending a plate made of high-strength steel into an L-shape, and bending inwardly at the middle of the two pieces 42a, 42b. The L-shaped base material 42 with 4 3b formed is provided, and a reinforcing member 4 4 made of a high-strength steel material bent at the bent corner 4 2c of the L-shaped base material 4 2 is fixed by welding. In addition, a cushioning member 45 made of vibration-absorbing rubber or the like is locked at several places of the L-shaped base material 42.
これによれば、 L形基材 4 2全体及びその折曲膨出部 4 3 a , 4 3 bに より、 垂直、 水平両方向の強い振動を吸収して L形基材 4 2の変形を復元 することができるから、 強い振動が負荷されても木造建築物が接合部にお いて容易に破壊したり倒壊することは少ない。 しかし、 上記補強金具 4 1は L型形状の基材 4 2であって、 該基材 4 2 の両片が、 その構造上、 直交する構造材同士の同一内面側に跨設して取付 けなければならないと云う制約があるものであり、 例えば、 接合しようと する構造材相互間に他の構造材が存在する場合など、 それが邪魔立ちして 補強金具 4 1の取付けができないと云う不都合を生ずる。 According to this, strong deformation in both vertical and horizontal directions is absorbed by the entire L-shaped base material 42 and the bent bulging portions 43a, 43b to restore the deformation of the L-shaped base material 42 Wooden buildings are not easily destroyed or collapsed at joints even under strong vibration. However, the reinforcing metal member 41 is an L-shaped base member 42, and both pieces of the base member 42 are mounted so as to straddle the same inner surface side of orthogonal structural members due to the structure. There is a restriction that it must be used. For example, when there is another structural material between the structural materials to be joined, it interferes with the installation of the reinforcing metal fittings 41. Is generated.
また、 L形基材 4 2に補強部材 4 4を溶接により固着させ、 L形基材 4 2の折曲角部 4 2 cと捕強部材 4 4の折曲角部 4 4 cとを密着させてある ので、 弾性変形量は小さく、 L形基材 4 2の変形を復元する効果も不十分 であった。 発明の開示  In addition, the reinforcing member 44 is fixed to the L-shaped base material 42 by welding, so that the bent corner portion 4 2c of the L-shaped base material 42 and the bent corner portion 4 4c of the reinforcing member 44 are in close contact with each other. Therefore, the amount of elastic deformation was small, and the effect of restoring the deformation of the L-shaped substrate 42 was insufficient. Disclosure of the invention

Thereafter, the fixing piece 11 on the lower side of the other reinforcing base 1 is fixed to the beam member A-1 via the buffer member 2 using the fixing tool 3, and then the upper side of the upper side of the other reinforcing base 1 is fixed. Fix the fixing piece 1 1 along the three faces a3 and four faces a4 of the bundled column member A-2, and fix it using the fixture 3 via the buffer member 2 attached to the end piece 17 of the fixing piece 11 Thus, the beam member A-1 of the structural material A and the bundle member A-2 can be securely joined.
そして、 上記両方の補強基材 1， 1共に、 他の構造材 Bを避けて梁部材 A— 1 と束柱部材 A— 2間を確実に接合することができる。  In addition, both the reinforcing base materials 1 and 1 can securely connect the beam member A-1 and the bundled column member A-2 while avoiding the other structural material B.
上記実施例では、 本発明を建築構造材 Aの梁部材 A— 1 と束柱部材 A— 2間を接合する場合について説明したが、 これに拘束されるものではなく、 拄部材と桁部材間、 或いは梁部材と桁部材間等の接合に有効に使用するこ とができるものである。  In the above embodiment, the present invention has been described for the case where the beam member A-1 of the building structural material A is joined to the bundle member A-2. However, the present invention is not limited to this. Alternatively, it can be effectively used for joining between a beam member and a girder member.
上記本発明により、 図 2に示す如く、 例えば接合しょうとする建築構造 材 Aの梁部材 A— 1 と束柱部材 A— 2との相互間に他の構造材 Bが存在し ている場合に、 補強金具の取付けができないと云う従来の不都合を回避す ることができると共に、 補強基材 1に形成した折曲膨出部 1 3や湾曲膨出 部 1 4、 或いは、 クッションラウンド 1 5の形成と相俟って、 建築構造材 Aと補強基材 1間にゴム弾性を有する緩衝部材 2が介在することにより、 建築構造材 Aに加わる垂直方向や水平方向の振動、 鉛直回りの揺動が吸収 されると共に復元力が増幅されるので、 地震、 台風等により木造家屋に強 度の振動が負荷されても片寄りや捩れに対する対抗力が増し、 耐震性能が 一層向上すると云う作用効果が得られる。 According to the present invention, as shown in FIG. 2, for example, when another structural material B exists between the beam member A-1 and the bundled column member A-2 of the building structural material A to be joined. In addition to avoiding the conventional inconvenience of not being able to attach the reinforcing bracket, the bent bulged portion 13 and the curved bulged portion 14 formed on the reinforcing base material 1 or the cushion round 15 can be formed. Together with the formation, the cushioning member 2 having rubber elasticity is interposed between the building structural material A and the reinforcing base material 1, The vertical and horizontal vibrations applied to the structural material A and the vertical oscillations are absorbed and the restoring force is amplified, so that even if strong vibration is applied to the wooden house due to an earthquake, typhoon, etc. The effect of increasing the resistance to leaning and twisting and further improving seismic performance is obtained.
本発明は上記構成よりなるので下記効果を奏する。  Since the present invention has the above configuration, the following effects can be obtained.
即ち、 本発明により、 建築構造材に加わる垂直方向や水平方向の振動、 鉛直回りの揺動が吸収され復元力が増幅されるので、 地震等により木造家 屋に強度の振動が負荷されても対抗力が増して耐震性能が一層向上すると 共に、 接合しょうとする構造材相互間に他の構造材が存在していても、 該 他の構造材を避けて補強金具の取付けができるので大変便利であると云う 作用効果を奏するものである。  That is, according to the present invention, vertical and horizontal vibrations and vertical vibrations applied to the building structural material are absorbed and the restoring force is amplified, so that even if a strong vibration is applied to the wooden house due to an earthquake or the like. This is very convenient because the counterforce is increased and the seismic performance is further improved, and even if there is another structural material between the structural materials to be joined, the reinforcing bracket can be attached avoiding the other structural materials. It has the function and effect.
