Description

【０００１】
【発明の属する技術分野】
この発明は、住宅等の建築において、柱、土台、梁、桁等の木質構造材同士の接合や、当該木質構造材と布基礎等のコンクリート構造材との接合、あるいはこれらと鋼構造材との接合、さらには鋼構造材同士の接合を行うために使用する接合金具に関するものである。
【０００２】
【従来の技術】
住宅等の建築において、柱と梁等の接合に際しては、旧来よりそれら柱等に「ほぞ」や「ほぞ穴」等の継ぎ手加工を施して行ってきた。また、明治以降、西洋からボルトとナットを使用する工法が伝来し、更に、最近では各種の金具が創案され使用されている。
【０００３】
本出願人も、図９に示すような、パイプ等の棒片とこれに直交する複数の取付ピン１０ｂを使用した接合金具１０を開発した（特願２０００−１８７２４３）。そして、これを使用することで施工の簡易化を図ることのできる手段の研究を続けている。
【０００４】
この接合金具１０は比較的簡単な構造で、接合部分の強度を飛躍的に高めることが可能なので、最近では採用が増えている。また、この接合金具１０は、通常、取付けに精度が要求されるので、高精度の加工機械の備え付けられた工場等において柱等の構造材の所定位置に穿孔しておいて、施工現場では、これらの孔に棒片１０ａを装着し、構造材と接合金具１０を連通する取付ピン１０ｂを打ち込んで固定する施工手段が採られている。
【０００５】
【発明が解決しようとする課題】
しかしながら、上記の接合金具１０を使用した施工は、次に示すような改善すべき点がある。
（１）施工に時間がかかる。
多数の取付ピン１０ｂを打ち込む必要があるので、施工に時間を要する。取付ピン１０ｂの数を減少させれば施工時間の減少が図れるが、それでは強度の低下を招く恐れが有る。
（２）バリエーションが多数必要。
接合しようとする構造材に合わせてそれぞれ最適な取付ピン１０ｂの数が決まってくるが、そうなると必然的に多くの種類の棒片１０ａを予め用意しておく必要がある。例えば、被接合材が４種類あって、それぞれに異なった本数の取付ピン１０ｂが必要だとすると、１６種類の接合金具１０を準備する必要がある。
（３）撤去に時間がかかる。
一旦解体等する場合に、施工時と同様に多数の取付ピン１０ｂを撤去しなければならないので、多くの時間がかかる。
（４）破損しやすい。
接合する構造材の一方に棒片１０ａを工場等で予め取り付けておく事も考えられるが、施工時に構造材が衝突したりすると、曲がったりして破損しやすい。従って、輸送時には取り付けたままでは破損の危険性があり、このため実際には、破損防止のため施工の直前に取り付ける必要が有る。
（５）ガタツキが生じやすい。
仮設建造物等の何度か組立・解体を必要とする建築物では、２回目以降の組立においては、同じ孔に取付ピン１０ｂを打ち込むので、初回に比較して緩く接合される。従って、ガタツキが生じやすい。
（６）施工ミスの恐れがある。
上記（２）に示したように、バリエーションが多数必要なので、金具１０を取り違える恐れが有る。万一取り付けを誤ると、再び多数の取付ピン１０ｂの撤去および取付けが必要である。
【０００６】
そこで本発明の目的とするところは、施工時間が短くて済み、多くのバリエーションを必要とせず、撤去にも時間が掛からず、破損し難く、ガタツキが生じ難く、さらに施工ミスの恐れがない接合金具を提供することにある。

【００２１】
【発明の実施の形態】
図１および図２を参照して、本発明の第一実施形態に係る接合金具１について説明する。図１は接合金具１の連結部材４を連結する前の状態を示す斜視図であり、図２は連結後を示す斜視図である。従来例で示したものと同一部分には同一符号を付した。
【００２２】
本発明の第一実施形態に係る接合金具１は、二本の構造材９同士（ここでは柱と梁の場合を示したが、これに限定されることなく例えば柱と柱の場合や梁と梁の場合等もある）を固定するために両構造材９間に設けられる接合金具であって、一対の接合部材の一例を示す棒材２と複数の固定ピン３と、そして連結部材４とで構成される。本実施形態においては、二つの接合金具１を使用している。
棒材２は、両構造材９の当接面から各構造材９の内部に向かって直線的に開けた孔に全体が差込まれ、長手方向に複数の貫通孔２ａを所定間隔で穿設したものである。固定ピン３は、その棒材２の貫通孔２ａに相対するように一方の構造材９（柱）の一側面に水平に開けられた複数の差込孔と、他方の構造材９（梁）の二側面に開けられた複数の差込孔を介して前記複数の貫通孔２ａに差込まれ、棒材２を構造材９に固定する。
また、連結部材４は、前記一対の棒材２間に着脱自在に介在し、両棒材２を着脱自在に連結することによって両構造材９を接合する。そして、接合部材となる棒材２と固定ピン３は、構造材９が施工現場に搬送されるに先立って、工場で機械によって自動的に取付けられるものである。
【００２３】
この連結部材４は、一対の部材で構成され、各部材の構造材９側である後端部に螺条部４ａを形成して対応する棒材２に螺合結合し、構造材９側とき逆側となる相互に対向する側である前端部に凹部４ｂと凸部４ｃを形成して嵌込み結合している。凹部４ｂと凸部４ｃは、例えば図１や図３に示す形態がある。
【００２４】
本実施形態に係る接合金具１において、棒材２と固定ピン３は、工場で機械によって自動的に取付けられるので、施工現場では、連結部材４を接合するのみで良く、従って、施工時間を大幅に短縮することができる。また、棒材２と固定ピン３は予め構造材９に取付けられるので、施工現場でピンの数を揃える必要がなく、よって、構造材９によって異なるバリエーションを考慮する必要がない。また、連結部材４は棒材２間に着脱自在であるため、建築物を一旦解体等する場合でも、容易に取り外すことができ、作業時間を短縮することができる。また、棒材２は、その全体が構造材９の孔に差込まれているので突出しておらず、従って、構造材９を搬送する際に障害物にぶつかって破損することがない。さらに、連結部材４が棒材２間に着脱自在に介在しているので、仮設建造物等の複数回におよぶ組立てと解体を必要とする場合でも連結部分が緩むことがなく、よってガタツキが生じない。またさらに、施工現場では、連結部材４だけを取付けるといった容易な作業で構造材９を接合することができるので、施工ミスの恐れがない。なお、連結部材４を一対の部材で構成し、螺合結合と嵌込み結合によって構造材９を接合しているので、取付けや取外しが容易であり、よって施工時間をより短縮することができる。
【００２５】
なお、連結部材４は、図４および図５に示すように、一つの部材で構成し、その一方端部に右螺子部４ｄを形成して対応する棒材２に螺合結合し、他方端部に左螺子部４ｅを形成して対応する棒材２に螺合結合することができる。
さらに、この連結部材４は、図６に示すように、一つの部材で構成し、その一方端部に凸部４ｃを形成して対応する棒材２に回転自在に嵌込み結合し、他方端部に螺条部４ａを形成して対応する棒材２に螺合結合するものでも良い。
これらの連結部材４は一つの部材で構成しているので、二つの部材で構成する場合と比較して部材数を削減することができ、製造コストの低廉化を図ることができる。
【００２６】
本実施形態においては、接合部材として棒材２と複数の固定ピン３を例としてあげたが、構造材９に予め差し込まれることにより取付けられるもので、連結部材４によって連結されるものであればよい。
なお、棒材には図示した丸材の他に角材も含まれる。
【００２７】
図７および図８を参照して、本発明の第二実施形態に係る接合金具１について説明する。図７は接合金具１の連結部材４を連結する前の状態を示す斜視図であり、図８は連結後を示す斜視図である。ここでも、従来例で示したものと同一部分には同一符号を付した。
【００２８】
本発明の第二実施形態に係る接合金具１は、二本の構造材９同士（ここでは柱とコンクリート製の布基礎）を固定するために両構造材９間に設けられる接合金具１であって、棒材２、複数の固定ピン３、連結プレート５および連結具６で構成される。
【００２９】
棒材２は、一方の構造材９（柱）の当接面から当該構造材９の内部に向かって直線的に開けた孔に全体が差込まれ、長手方向に複数の貫通孔２ａを所定間隔で穿設したものである。複数の固定ピン３は、棒材２の貫通孔２ａに相対するように構造材９の二側面に開けられた複数の差込孔を介して前記複数の貫通孔２ａに差込まれ、棒材２を構造材９に固定する。また、連結プレート５は、他方の構造材９（布基礎）にアンカーボルト７とナット８で固定されるプレート部５ａから二つの接続部５ｂを突設したものである。さらに、連結具６は二つ設けられ、それぞれが棒材２と連結プレート５の接続部５ｂとの間に着脱自在に介在し、当該棒材２と接続部５ｂを着脱自在に連結することによって両構造材９を接合する。そして、棒材２と固定ピン３は、構造材９が施工現場に搬送されるに先立って、工場で機械作業により自動的に取付けられるものである。
【００３０】
本実施形態における連結具６は、一つの部材で構成し、その一方側にネジ部６ａを形成して棒材２に螺合結合し、他方側に嵌合部６ｂを形成し、連結プレート５の接続部５ｂに嵌込み結合している。なお、本実施形態における接合金具１は、柱と布基礎を接合しているが、柱と梁を接合することもできる。
【００３１】
本実施形態に係る接合金具１においても、棒材２と固定ピン３は、工場で機械によって自動的に取付けられるので、施工時間を大幅に短縮することができる。また、棒材２と固定ピン３は予め構造材９に取付けられるので、構造材９によって異なるバリエーションを考慮する必要がない。また、連結具６は棒材２間に着脱自在であるため、建築物を一旦解体等する場合でも、容易に取り外すことができ、作業時間を短縮することができる。また、棒材２は、その全体が構造材９の孔に差込まれているので、構造材９を搬送する際に破損することがない。さらに、連結具６が棒材２間に着脱自在に介在しているので、複数回におよぶ組立てと解体を必要とする場合でもガタツキが生じない。またさらに、施工現場では、連結具６を取付けるといった容易な作業で構造材９を接合することができるので、施工ミスの恐れがない、といった多くの作用効果を発揮する。
【００３２】

以上のとおり、本発明の請求項１乃至３に記載の接合金具によれば、以下の効果が発揮される。
（１）接合部材は、構造材が施工現場に搬送されるに先だって工場等で取付けられる。従って、施工現場では、連結部材を棒材間に介在させて、二本の構造材を接合するのみで良く、施工時間を大幅に短縮することができる。これにより、作業性の向上と建設コストの削減を図ることができる。
（２）例えば棒材と固定ピンとからなる接合部材の場合、予め構造材に取付けられることから、施工現場でピンの数を揃える必要がない。したがって、構造材によって異なるバリエーションを考慮する必要がない。これによっても作業性の大幅な向上と建設コストの削減を図ることができる。

BACKGROUND OF THE INVENTION
In the construction of a house or the like, the present invention can be used for joining wooden structures such as columns, foundations, beams, girders, joining the wooden structures and concrete structures such as cloth foundations, and steel structures. In addition, the present invention relates to a joint fitting used for joining steel structural materials.
[0002]
[Prior art]
In the construction of houses, etc., when connecting columns and beams, etc., joints such as “mortise” and “mortise” have been applied to these columns from the past. Also, since the Meiji era, construction methods using bolts and nuts have been introduced from the West, and recently, various metal fittings have been created and used.
[0003]
The present applicant has also developed a joint fitting 10 using a bar piece such as a pipe and a plurality of mounting pins 10b orthogonal to the pipe piece as shown in FIG. 9 (Japanese Patent Application No. 2000-187243). And we continue research on means that can simplify the construction by using this.
[0004]
Since the joining metal fitting 10 has a relatively simple structure and can greatly increase the strength of the joining portion, it has been increasingly used recently. In addition, since this fitting 10 is usually required for accuracy in installation, it is drilled at a predetermined position of a structural material such as a pillar in a factory or the like equipped with a high-precision processing machine. A construction means is employed in which the rod pieces 10a are mounted in these holes, and the mounting pins 10b for communicating the structural material and the joint fitting 10 are driven and fixed.
[0005]
[Problems to be solved by the invention]
However, the construction using the joint fitting 10 has the following points to be improved.
(1) Construction takes time.
Since it is necessary to drive a large number of mounting pins 10b, it takes time for the construction. If the number of mounting pins 10b is reduced, the construction time can be reduced, but this may cause a reduction in strength.
(2) Many variations are required.
The optimum number of mounting pins 10b is determined in accordance with the structural materials to be joined. In this case, it is inevitably necessary to prepare many kinds of rod pieces 10a in advance. For example, if there are four types of materials to be joined and each requires a different number of mounting pins 10b, it is necessary to prepare 16 types of joint fittings 10.
(3) It takes time to remove.
When dismantling and the like once, it takes a lot of time because a large number of mounting pins 10b must be removed as in the construction.
(4) Easy to break.
Although it is conceivable that the rod piece 10a is previously attached to one of the structural materials to be joined at a factory or the like, if the structural material collides at the time of construction, it is easily bent and damaged. Therefore, there is a risk of damage if it is attached during transportation, and therefore it is actually necessary to attach it immediately before construction in order to prevent damage.
(5) Backlash is likely to occur.
In a building that requires several times of assembly / disassembly, such as a temporary building, the mounting pin 10b is driven into the same hole in the second and subsequent assembly, so that they are loosely joined as compared to the first time. Therefore, rattling is likely to occur.
(6) There is a risk of construction errors.
As shown in the above (2), since many variations are necessary, there is a possibility that the metal fitting 10 is mistaken. If the attachment is wrong, it is necessary to remove and attach many attachment pins 10b again.
[0006]
Therefore, the purpose of the present invention is to shorten the construction time, do not require many variations, do not take much time to remove, are not easily damaged, do not easily rattle, and are not susceptible to construction errors. It is to provide metal fittings.
[0007]
[Means for Solving the Problems]
