【０００１】
【発明の属する技術分野】
本発明は、ログ材を用いた組立家屋の壁構造に関する。
【０００２】
【従来の技術】
ログ材を用いた組立家屋の壁は、一般に、水平方向における向きを互いに９０°異ならせた第１の群のログ材と第２の群のログ材とをそれらの端部において下から上へと交互に重ねていくようになされており、ログ材の端部に深くて大きな切欠き加工が施されていて、これら切欠き部同士を嵌合することで、ログ材が各群において上下方向に隙間なく重なるようになされている。
【０００３】
【発明が解決しようとする課題】
しかしながら、上記のような構造では、ログ材の端部にログ材間の間隙をなくすための深くて大きい切欠き加工を施さなければならず、そのための加工や、そのようなログ材の製作が非常に厄介であるという問題がある。
【０００４】
本発明は、上記のような問題点に鑑み、壁を構成する各群のログ材から従来のような深くて大きな切欠きを排除することができ、それでいて、無用な風雨が入るのを防ぐことができるログ材を用いた組立家屋の壁構造を提供することを課題とする。
【０００５】
【課題を解決するための手段】
上記の課題は、複数本のログ材からなり、それらが水平方向を向いて上下方向に並列状態となるよう互いに平行に並べられる第１のログ材群と、
同じく、複数本のログ材からなり、それらが水平方向を向いて上下方向に並列状態となるよう互いに平行に並べられる第２のログ材群と
が備えられ、
第１の群のログ材と第２の群のログ材とが、各群のログ材間に間隙を形成するように、それらの端部又は中間部において下から上へと交互に重ねられ、
前記間隙にプレートが設置されて壁を形成していることを特徴とするログ材を用いた組立家屋の壁構造を提供することを課題とする。
【０００６】
この壁構造では、そもそも、第１の群のログ材と第２の群のログ材とを、各群のログ材間に間隙が形成されるように重ねていくようにしているので、各群のログ材から従来のような深くて大きい切欠きを排除することができ、ログ材の加工や製作を容易に行うことができる。しかも、各群のログ材間の間隙にはプレートを設置するようにしているので、無用な風雨が入るのを防ぐことができる。
【０００７】
加えて、各群のログ材間に間隙を形成し、間隙にプレートを設置して壁を形成するようにしているので、プレートの設置される部分に足をかけることができ、下のログ材を足場にしながら高所のログ材の積み上げを行っていくことができ、脚立などの足場を別途用意する必要性を低くすることができる。また、各間隙においてプレートを挟むいずれか一方又は両方を収納に用いることも可能である。
【０００８】
また、前記プレートの少なくとも一部が透光板からなる場合は、家屋の中に壁を通じて採光することができ、壁側からの採光のために壁にわざわざ開口部を形成する必要もなくなる。
【０００９】
また、各群において、上ログ材の下面に溝が設けられると共にこのログ材と隣り合う下ログ材の上面に溝が設けられ、プレートがこれら上下の溝に差し込まれて上下のログ材間に保持されている場合は、ログ材の上面の溝にプレートの下部を差し込み、その上に次のログ材を重ねるに際してそのログ材の下面の溝にプレートの上部を差し込むというようにしてプレートを設置していくことができ、ログ材間の間隙内へのプレートの設置を容易に行っていくことができる。
【００１０】
また、ログ材には、それらの重ねられる部分の下面と上面のそれぞれに位置決め用の凹所が備えられ、ログ材の上面凹所にインサート部材が上方に突出するように嵌合され、該インサート部材の上方突出部が上側のログ材の下面の凹所に嵌合されることにより、隣り合う上下のログ材が水平方向において位置決め状態に保持されるようになされているとよい。
【００１１】
この場合は、各群のログ材を交互に重ねていく過程で、それらのログ材が水平方向に変位して壁がくずれてしまうのをインサート部材が阻止し、ログ材を重ねていく作業を安全に行っていくことができる。
【００１２】
また、ログ材の上面凹所と下面凹所がそれぞれ円形凹所からなり、各円形凹所の内周面に凹所開口部側に開く溝が設けられ、
インサート部材は円形凹所内にしっくり嵌合するよう外周が円形であって、その高さ方向の両端部を除く中間部に、隣り合う上下のログ材の対向する円形凹所の両溝内に突出する突起が備えられ、突起と溝との嵌合により、隣り合う上下のログ材の相対回転が規制されるようになされているとよい。
【００１３】
この場合は、インサート部材の突起とログ材の溝との係合作用により、第１の群のログ材と第２の群のログ材をそれぞれ正確に所定の向きに向けて重ねていくことができる。
【００１４】
しかも、ログ材上面凹所へのインサート部材の嵌合は、まず、インサート部材の端部の外周円形部を、回転方向における位置を気にせずに、ログ材の円形凹所内に嵌合させるようにすればよく、次いで、この嵌合状態においてインサート部材を回転させていけば、その過程で突起と円形凹所の溝とが一致し、突起が溝内に嵌まり込み、それにより、回転方向におけるインサート部材の位置が決まり、ログ材上面凹所へのインサート部材の嵌合を容易に行うことができる。
【００１５】
また、インサート部材へのログ材下面凹所の嵌合についても、まずログ材下面の円形凹所を、ログ材の回転方向における位置を気にせずに、インサート部材の端部の外周円形部と嵌合させるようにし、次いで、この嵌合状態においてログ材を首振りさせれば、その過程で突起と円形凹所の溝とが一致し、突起が溝内に嵌まり込んで、回転方向におけるログ材の位置が決まり、インサート部材へのログ材下面凹所の嵌合も容易に行うことができる。
【００１６】
更に、ログ材には、それらの重ねられる部分において上下方向に貫通する連結孔が設けられると共に、各インサート部材に該連結孔と同心に連結孔が設けられ、これら連結孔を貫通するように連結棒が差し込まれてログ材同士が連結されているとよい。このように、連結棒が通しで差し込まれてログ材同士が連結されるので、壁構築後に外力によって壁がくずれてしまうのを確実に防ぐことができる。この場合に、各インサート部材に前記結孔と同心に連結孔が設けられ、連結棒が各インサート部材の連結孔にも通されている場合は、ログ材同士の心合わせをインサート部材で行わせることができ、連結棒の挿入を容易に行うことができる。
【００１７】
【発明の実施の形態】
次に、本発明の実施形態を図面に基づいて説明する。
【００１８】
図１に示す実施形態の組立家屋は、家族でも庭先等に楽しみながら楽に組み立てられる簡易家屋に構成されているもので、１は基礎、２は壁、３は屋根、１６は床である。なお、４は出入り口である。基礎１は樹脂タンクからなっていて内部に水を入れることで基礎としての重量を確保できるようになされたものであり、屋根３は開閉式で夜間に開いて天体観測をしたり、新鮮な空気を取り入れることなどができるようになっており、床１６は壁２に用いるのと同じログ材を多数隣接並列状態に並べて構成したものであるが、基礎、屋根、床はこれらに限られるものではない。
【００１９】
壁２は、ログ材を用いて形成されている。即ち、壁２には、図１（ロ）、図２及び図７に示すように、複数本のログ材５ａ…，６ａ…で構成される第１、第２のログ材群５，６が備えられ、各群５，６において、ログ材５ａ…，６ａ…はそれぞれ、水平方向を向いて上下方向に並列状態となるよう互いに平行に並べられる。
【００２０】
各群５，６のログ材５ａ…，６ａ…はそれぞれ、図３に示すように、角材からなっていて、通常の木材が用いられてもよいが、本実施形態ではリサイクル材を使用し、芯部を低発泡、外周側を高発泡とした木樹脂による軽量人工木材が用いられている。なお、ログ材５ａ…，６ａ…に丸材などが用いられてもよく、外周形状に特に制限はない。
【００２１】
そして、第１の群５のログ材５ａ…と第２の群６のログ材６ａ…とは、図１（ロ）、図２及び図７に示すように、向きを水平方向に９０°異ならせ、各群５，６においてログ材間に間隙７…が形成されるように、各群５，６のログ材５ａ…，６ａ…がそれらの端部において下から上へと交互に重ねられ、かつ、ログ材５ａ…，６ａ…間の各間隙７…にはプレート８…が設置され、各群５，６のログ材５ａ…，６ａ…とプレート８…とで壁２を構成している。本実施形態では、プレート８…のすべてが、採光のため、アクリル板などの透光性を有する板で構成されているが、一部のプレートを透光板とし残りを不透光板としてもよいし、全部不透光板としてもよい。また、一部又は全部のプレートとしてガラリ板などの通風板を用いるようにしてもよい。
【００２２】
そして、プレート８の設置のため、次のような構造が採られている。即ち、各群５，６のログ材５ａ…，６ａ…の上下の面部には、図３に示すように、幅方向の中間部位置において、ログ材の全長にわたって延びるプレート上下差込み用の溝９，９が備えられている。これにより、プレート８は、各群５，６において、その下部が下ログ材の上面の差込み溝９に差し込まれると共に、上部が上ログ材の下面の差込み溝９に差し込まれ、それによって、上下のログ材間の間隙７内に保持されるようになされている。
【００２３】
更に本実施形態では、各群５，６のログ材５ａ…，６ａ…の端部の両側の側面部に高さ方向の全長にわたって延びる端部開放のプレート側部差込み用の溝１０，１０が備えられ、プレート８の上下が一方の群５の上下のログ材５ａ，５ａの向き合う差込み溝９，９に差し込まれた状態で、プレート８の側部がもう一方の群６のログ材６ａの端部の側面の差込み溝１０に差し込まれて、プレート８がよりしっかりと保持されるようになされている。
【００２４】
第１、第２の群５，６のログ材５ａ…，６ａ…は、第１の群５のログ材５ａの端部の上面に第２の群６のログ材６ａの端部を重ね、このログ材６ａの端部上面に第１の群５のログ材５ａの端部を重ね、このログ材５ａの端部上面に第２の群６のログ材６ａの端部を重ねることを繰り返して組み立てられていくが、そのなかで、プレート８は、第２の群６のログ材６ａの端部を重ねた後であって第１の群５の次のログ材５ａの端部を重ねる前に、プレート８の側部を、第２の群６のログ材６ａの側部差込み溝１０に上方より差し込み、下方にスライドさせ、その下部を第１の群５のログ材５ａの上面の差込み溝９に差し込み、そして、第１の群５の次のログ材５ａを重ねて、その下面の差込み溝９にプレート８の上部を差し込み状態にするというようにしてログ材５ａ…間に組み込まれていく。第２の群６のログ材６ａ…間のプレート８…についても同様である。
【００２５】
こうしてログ材５ａ…，６ａの端部を重ねて壁２を形成していくなかで、ログ材５ａ…，６ａ…の端部が水平方向に位置ズレを起こさないように、次のような構造が採用されている。即ち、図３に示すように、各群５，６のログ材５ａ，６ａの端部の上下の面にはそれぞれ位置決め用の凹所１１，１１が備えられ、図４に示すように、一方の群６のログ材６ａの上面凹所１１にインサート部材１２が上方に突出するように嵌合され、該インサート部材１２の上方突出部がもう一方の群５の上側のログ材５ａの下面の凹所１１に嵌合され、それにより、隣り合う上下のログ材５ａ，６ａが水平方向において位置決め状態に保持されるようになされている。
【００２６】
更に、各群５，６のログ材５ａ…，６ａ…がそれぞれ所定の方向を向いて重ねられていくように、次のような構造が採用されている。
【００２７】
即ち、上記の上下の凹所１１，１１はそれぞれ円形凹所からなっていて、各円形凹所１１，１１の内周面に凹所開口部側に開く２つの溝１３，１３が備えられている。更に、本実施形態では、プレート８の上下を差し込む差込み溝９が円形凹所１１を横断し、この差込み溝１１も凹所開口部側に開く溝として機能するようになされていて、円形凹所１１には、周方向に４つの溝が備えられている。なお、この溝は少なくとも一つ備えられていればよく、また、円形凹所１１を横断するプレート差込み溝９のみで溝を構成するようにしてもよい。
【００２８】
そして、インサート部材１２は、図４乃至図６に示すように、上記の円形凹所１１内にしっくり嵌合するよう外周が円形をしていて、高さ方向の両端部を除く中間部に、隣り合う上下のログ材５ａ，６ａの対向する円形凹所１１,１１内の両溝１３…，１３…内に突出する突起１２ａ…が備えられ、突起１２ａ…と溝１３…，１３…との嵌合により、隣り合う上下のログ材５ａ，６ａの相対回転が規制され、各群５，６のログ材５ａ…，６ａ…がそれぞれ所定の方向を向いて重ねられていくようになされている。
【００２９】
また、このような構造を採用することで、インサート部材の嵌込みを容易に行うことができる。
【００３０】
即ち、ログ材６ａの上面凹所１１へのインサート部材１２の嵌合は、まず、図５（イ）に示すように、インサート部材１２の端部の外周円形部１２ｂを、回転方向における位置を気にせずに、ログ材６ａの円形凹所１１内に嵌合させるようにすればよく、次いで、図５（ロ）に示すように、この嵌合状態においてインサート部材１２を回転させていけば、その過程で突起１２ａ…と円形凹所１１の溝１３…とが一致し、図５（ハ）に示すように、突起１２ａ…が溝１３…内に落ち込み、それにより、回転方向におけるインサート部材１２の位置が決まる。こうして、ログ材６ａの上面凹所１１へのインサート部材１２の嵌合を容易に行うことができる。
【００３１】
また、インサート部材１２へのログ材５ａの下面凹所１１の嵌合についても、まず、図６（イ）に示すように、ログ材５ａの下面円形凹所１１を、回転方向における位置を気にせずに、インサート部材１２の端部の外周円形部１２ｂと嵌合させるようにし、次いで、図６（ロ）に示すように、ログ材５ａを首振りさせれば、その過程で突起１２ａ…と円形凹所１１の溝１３…とが一致し、図６（ハ）に示すように、突起１２ａ…が溝１３…内に嵌まり込み、それにより、回転方向におけるログ材５ａの位置が決まり、インサート部材１２へのログ材５ａの下面凹所１１の嵌合も容易に行うことができる。
【００３２】
そして、各群５，６のログ材５ａ…，６ａ…の端部をインサート部材１２…を用いて交互に重ねていって壁を形成したのち、ログ材５ａ…，６ａ…の不本意な浮き上がりによって壁２がくずれてしまわないよう、次のような構造が採られている。即ち、図７に示すように、各群５，６のログ材５ａ…，６ａ…の端部には、上下の凹所１１，１１内の中央側に位置して上下方向に貫通する連結孔１４…が設けられると共に、インサート部材１２…には該連結孔１４と同心に連結孔１２ｃが設けられ、これら連結孔１４…，１２ｃ…を貫通するように連結棒１５が差し込まれて各群５，６のログ材５ａ…，６ａ…同士が連結されている。連結棒１５は、単に差し込まれているだけであってもよいし、ログ材５ａ…，６ａ…が上下方向に変位するのを規制するように差し込まれていてもよいし、ログ材５ａ…，６ａ…が上下方向において緊結されるように差し込まれていてもよい。こうして形成された壁２の上に屋根３を設置することで図１に示すような家屋の壁２が形成される。
【００３３】
このように、上記の壁２では、そもそも、第１の群５のログ材５ａ…と第２の群６のログ材６ａ…とを、各群５，６のログ材５ａ…，６ａ…間に間隙７…が形成されるように重ねていくようにしているので、各群５，６のログ材５ａ…，６ａ…から従来のような深くて大きな切欠きを排除することができ、ログ材の加工や製作を容易に行うことができる。しかも、各群５，６のログ材５ａ…，６ａ…間の間隙７…にはプレート８を設置するようにしているので、壁２を通じて無用な風雨が家屋の中に入るのを防ぐことができる。
【００３４】
加えて、各群５，６のログ材５ａ…，６ａ…間に間隙７…を形成し、間隙７…にプレート８…を設置して壁２を形成するようにしているので、プレート８…の設置される部分のログ材に足をかけて上方のログ材５ａ…，６ａ…やプレート８…の組付けを行っていくことができ、脚立などの足場を別途用意して組付けを行っていく必要性を少なくすることができるし、各間隙７においてプレートを挟むいずれか一方又は両方を収納に用いることも可能である。
【００３５】
更に、本実施形態では、プレート８…が透光板からなるので、家屋の中に壁を通じて採光することができ、採光のための開口部をわざわざ形成する必要がない。また、透光板からなるプレートの数を上下左右方向に増加することで壁全体からの採光も可能となり、明るい屋内を形成することができる。
【００３６】
以上に、本発明の実施形態を示したが、本発明はこれに限られるものではなく、発明思想を逸脱しない範囲で、各種の変更が可能である。例えば、上記の実施形態では、各群５，６のログ材５ａ…，６ａ…を互いに直交する方向に向けて端部同士を重ねた場合を示しているが、図８に示すように、各群５，６のログ材５ａ…，６ａ…を一直線上に直列に並べて端部同士を重ねるようにしてもよいし、あるいは、図示しないけれども、各群のログ材を互い直交する方向に向けて中間部同士を重ねるようにしてもよいし、一方の群のログ材の端部ともう一方の群のログ材の中間部とを重ねるようにしてもよい。また、上記の実施形態では庭などに家族で組み立てられる簡易な組立家屋の壁に適用した場合を示しているが、普通の組立家屋の壁に用いることも可能である。
【００３７】
【発明の効果】
本発明は、以上のとおりのものであるから、壁を構成する各群のログ材から従来のような深くて大きな切欠きを排除することができてログ材の加工や製作を容易に行うことができ、それでいて、無用な風雨が入り込むのを防ぐことができる。

BACKGROUND OF THE INVENTION
The present invention relates to a wall structure of an assembly house using a log material.
[0002]
[Prior art]
The wall of an assembly house using log materials generally has a first group of log materials and a second group of log materials that are 90 ° different from each other in the horizontal direction from the bottom to the top at their ends. It is made to overlap with each other, deep and large notch processing is given to the end of the log material, and the log material is vertically moved in each group by fitting these notches It is made to overlap with no gap.
[0003]
[Problems to be solved by the invention]
However, in the structure as described above, it is necessary to perform a deep and large notch processing to eliminate the gap between the log materials at the end of the log material. There is a problem that it is very troublesome.
[0004]
In view of the above problems, the present invention can eliminate deep and large notches as in the past from each group of log members that constitute a wall, and yet prevent unnecessary wind and rain from entering. An object of the present invention is to provide a wall structure of an assembly house using a log material that can be used.
[0005]
[Means for Solving the Problems]
The above-mentioned problem is composed of a plurality of log materials, and a first log material group arranged parallel to each other so that they are in a parallel state in the vertical direction facing the horizontal direction,
Similarly, a plurality of log materials are provided, and a second log material group arranged parallel to each other so as to be in a parallel state in the vertical direction facing the horizontal direction,
The log material of the first group and the log material of the second group are alternately stacked from bottom to top at their end or middle so as to form a gap between the log materials of each group,
It is an object of the present invention to provide a wall structure of an assembly house using a log material, wherein a plate is installed in the gap to form a wall.
[0006]
In this wall structure, the log material of the first group and the log material of the second group are originally stacked so that a gap is formed between the log materials of each group. Thus, it is possible to eliminate a deep and large notch as in the past from the log material, and it is possible to easily process and manufacture the log material. In addition, since a plate is installed in the gap between the log members of each group, it is possible to prevent unnecessary wind and rain from entering.
[0007]
In addition, a gap is formed between the log members of each group, and a wall is formed by installing a plate in the gap, so that the portion where the plate is installed can be put on, and the lower log member It is possible to pile up log materials in high places while using as a scaffolding, and it is possible to reduce the need for separately preparing a scaffolding such as a stepladder. Moreover, it is also possible to use either one or both of which sandwich the plate in each gap for storage.
[0008]
In addition, when at least a part of the plate is made of a translucent plate, the light can be taken through the wall in the house, and there is no need to bother to form an opening in the wall for daylighting from the wall side.
[0009]
In each group, a groove is provided on the lower surface of the upper log material and a groove is provided on the upper surface of the lower log material adjacent to the log material. If it is held, insert the plate so that the lower part of the plate is inserted into the groove on the upper surface of the log material, and the upper part of the plate is inserted into the groove on the lower surface of the log material when the next log material is stacked on it. The plate can be easily installed in the gap between the log members.
[0010]
In addition, the log material is provided with a positioning recess on each of the lower surface and the upper surface of the overlapping portion, and the insert member is fitted into the upper surface recess of the log material so as to protrude upward, the insert It is preferable that the upper and lower log members adjacent to each other are held in a positioned state in the horizontal direction by fitting the upper protruding portion of the member into the recess on the lower surface of the upper log member.
[0011]
In this case, in the process of alternately stacking the log materials of each group, the insert member prevents the log materials from being displaced in the horizontal direction and the wall from collapsing, and the operation of stacking the log materials is performed. You can go safely.
[0012]
Further, the upper surface recess and the lower surface recess of the log material are each composed of a circular recess, and a groove that opens to the recess opening side is provided on the inner peripheral surface of each circular recess,
The insert member has a circular outer periphery so that it fits well into the circular recess, and protrudes into both grooves of the adjacent circular recesses of the adjacent upper and lower log members at the intermediate portion excluding both ends in the height direction. It is preferable that a protrusion is provided, and the relative rotation of adjacent upper and lower log members is restricted by the fitting between the protrusion and the groove.
[0013]
In this case, the first group of log members and the second group of log members can be accurately stacked in a predetermined direction by the engaging action of the protrusion of the insert member and the groove of the log member. it can.
[0014]
In addition, the insertion of the insert member into the log material upper surface recess is performed by first fitting the outer peripheral circular portion of the end portion of the insert member into the circular recess of the log material without worrying about the position in the rotation direction. Then, if the insert member is rotated in this fitted state, the protrusion and the groove of the circular recess coincide with each other in the process, and the protrusion fits into the groove. The position of the insert member is determined, and the fitting of the insert member into the log material upper surface recess can be easily performed.
[0015]
In addition, with respect to the fitting of the log material lower surface recess to the insert member, first, the circular recess on the log material lower surface and the outer peripheral circular portion at the end of the insert member without regard to the position in the rotation direction of the log material Then, if the log material is swung in this fitted state, the protrusion and the groove of the circular recess coincide with each other in the process, and the protrusion fits in the groove, and in the rotational direction. The position of the log material is determined, and the recess of the log material lower surface to the insert member can be easily performed.
[0016]
Further, the log members are provided with connecting holes that penetrate in the vertical direction in the overlapping portions, and each insert member is provided with a connecting hole concentrically with the connecting hole, and is connected so as to pass through these connecting holes. It is good that the log material is connected by inserting a stick. In this way, since the connecting rods are inserted through and the log members are connected to each other, it is possible to reliably prevent the wall from collapsing due to an external force after the construction of the wall. In this case, when each connecting member is provided with a connecting hole concentrically with the connecting hole and the connecting rod is also passed through the connecting hole of each insert member, the log members are aligned with each other by the insert member. And the connecting rod can be easily inserted.
[0017]
