Description

【０００１】
【発明の属する技術分野】
本発明は、地震、台風等により木造建築物に強度の振動が負荷されても崩壊しないように、直交差して接続される建築構造材の接合部に取付けて、この接合部を弾発的に補強することを目的とする建築用補強金具に関する。
【０００２】
【従来の技術】
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型金具を取付けるなど種々の方法が採用されている。
しかし、これら補強具では、地震、台風等により強度の振動が負荷された場合に、建築構造材の接合部における振動を吸収する緩衝能力が不足しがちになるために、建築構造材から補強具が離脱したり、補強具が破損してしまう等のトラブルを招き、酷い場合にはこれが原因で木造建築物が倒壊してしまうこともある。
【０００３】
そこで、地震、台風等による強度の振動に耐え得るものとして、図６に斜視図で示すような補強金具６１が考案され、使用されている。
この補強金具６１は、高張力鋼よりなる板材をＬ字状に折曲すると共に、両片部６２１，６２２の各々の中間部に外側に折曲した折曲膨出部６２１ａ，６２２ａを各々形成したＬ形基材６２を設け、このＬ形基材６２の折曲角部６２３に高張力鋼よりなる板材を折曲した補強部材６３を溶接により固着し、上記Ｌ形基材６２の四ヶ所に吸震ゴム等よりなる緩衝部材６４を係着したものである。
【０００４】
これによれば、Ｌ形基材６２全体及びその折曲膨出部６２１ａ，６２２ａにより、垂直、水平両方向の振動がある程度吸収されるが、木造建築物に強い振動が負荷された場合に、変形したＬ形基材６２を復元させるには不十分であり、建築構造材相互の接合部で破損する虞れがある。
【０００５】
【発明が解決しようとする課題】
即ち、上述の如く、補強金具６１は、両片部６２１，６２２の中間部を外側に折曲して平坦な折曲膨出部６２１ａ，６２２ａを形成してあるだけなので、垂直方向の振動、鉛直回りの揺動を吸収したり、Ｌ形基材６２の変形を復元させる等の作用効果が不十分であると共に、Ｌ形基材６２に補強部材６３を溶接して、Ｌ形基材６２の折曲角部６２３と補強部材６３の折曲角部６３１との間が固着されているために、弾性変形量が少なくなって、補強部材６３に直接的に過大な集中負荷が加わることとなり、締結用のボルトが飛んだり補強部材６３に亀裂が生じたりするという問題があった。
【０００６】
本発明は、かかる問題点を解決すべく為されたものであって、垂直方向や水平方向の振動、鉛直回りの揺動を吸収して、地震、台風等により木造建築物に強度の振動が負荷されても崩壊しないように、直交差する建築構造材の双方に跨がって弾発的に補強する補強金具を固着して、耐震性能を一層向上させるようにした建築用補強金具を提供することを目的とする。

BACKGROUND OF THE INVENTION
The present invention attaches to a joint part of a building structure material connected at a right angle so that it does not collapse even if strong vibration is applied to a wooden building due to an earthquake, a typhoon, etc. The present invention relates to a reinforcing metal fitting for building intended to be reinforced.
[0002]
[Prior art]
Conventionally, as a method of reinforcing a joint portion of a structural member of a wooden building, various methods such as providing a brace or a fire beam, wiping, and attaching an L-shaped metal fitting have been adopted.
However, these reinforcing tools tend to have insufficient buffering capacity to absorb vibrations at the joints of building structural materials when strong vibrations are applied due to earthquakes, typhoons, etc. May cause troubles such as detachment or damage to the reinforcing tool. In severe cases, this may cause the wooden building to collapse.
[0003]
Accordingly, a reinforcing metal fitting 61 as shown in a perspective view in FIG. 6 has been devised and used as one that can withstand strong vibrations such as earthquakes and typhoons.
The reinforcing metal fitting 61 bends a plate made of high-strength steel into an L shape, and forms bent bulging portions 621a and 622a that are bent outward at intermediate portions of both pieces 621 and 622, respectively. The L-shaped base material 62 is provided, and reinforcing members 63 obtained by bending a plate material made of high-tensile steel are fixed to the bent corner portion 623 of the L-shaped base material 62 by welding. Further, a buffer member 64 made of a seismic absorbing rubber or the like is attached.
[0004]
According to this, vibrations in both the vertical and horizontal directions are absorbed to some extent by the entire L-shaped base material 62 and its bent bulging portions 621a and 622a, but when a strong vibration is applied to the wooden building, it is deformed. It is insufficient to restore the L-shaped base material 62, and there is a risk of damage at the joint between the building structure materials.
[0005]
[Problems to be solved by the invention]
That is, as described above, the reinforcing metal fitting 61 is formed by merely bending the intermediate portions of the two pieces 621 and 622 outward to form flat bent bulged portions 621a and 622a. The effects such as absorbing the swinging around the vertical and restoring the deformation of the L-shaped base material 62 are insufficient, and the reinforcing member 63 is welded to the L-shaped base material 62 so that the L-shaped base material 62 is welded. Since the bent corner portion 623 and the bent corner portion 631 of the reinforcing member 63 are fixed to each other, the amount of elastic deformation is reduced and an excessive concentrated load is directly applied to the reinforcing member 63. There is a problem that a fastening bolt is blown or a crack is generated in the reinforcing member 63.
[0006]
The present invention has been made to solve such problems, and absorbs vibrations in the vertical direction and horizontal direction, and swings in the vertical direction, and strong vibration is applied to the wooden building due to earthquakes, typhoons, and the like. Providing building reinforcement brackets that further improve seismic performance by fixing reinforcement brackets that elastically reinforce across both of the building structure materials orthogonal to each other so that they do not collapse even when loaded The purpose is to do.
[0007]
[Means for Solving the Problems]
The gist of the present invention is a reinforcing metal fitting for joining building structural materials orthogonal to each other, and is a bent portion of an equilateral mountain-shaped steel bent in an L shape, and a buffer curved portion bulging outward is formed. The first metal fitting and a second metal fitting provided at both ends with fixing portions fixed to both ends of the first metal fitting and having a buffer curved portion formed in the middle central portion, A construction reinforcing metal fitting characterized in that both fixing portions of two metal fittings are fixed to both orthogonal building structural materials to reinforce the joints of the building structural materials.
[0008]
