また、各ログ材40における、小口41側端部からノッチ部42（他のログ材40との交差部）までの間の部分は、ノッチエンド部43などと呼ばれる。つまり、各ログ材40における、ノッチ部42よりも先端側の部分が、ノッチエンド部43である。
また、各ログ材40の上面には、一方の小口41側端部から他方の小口41側端部まで至る、２本の凸条44が設けられている。これら２本の凸条44は、細長い突起であって、所定間隔を空けて平行に形成されている。
In addition, a notch portion 42 which is a recess formed by cutting out from the top, bottom, left and right is provided at a position a predetermined distance from the end portion of each log member 40 on the small mouth 41 side. The notch portion 42 becomes an intersecting portion with other log members 40 when the plurality of log members 40 are stacked while alternately intersecting.
In addition, a portion between each end of the log material 40 and the notch 41 side end portion to the notch portion 42 (intersection with the other log material 40) is referred to as a notch end portion 43 or the like. That is, the notch end portion 43 is a portion on the tip side of the notch portion 42 in each log member 40.
Further, on the upper surface of each log member 40, two ridges 44 extending from one end portion on the small edge 41 side to the other end portion on the small edge 41 side are provided. These two ridges 44 are elongated protrusions, and are formed in parallel at a predetermined interval.
また、各ログ材40の下面には、一方の小口41側端部から他方の小口41側端部まで至る、２本の凹条45が設けられている。これら２本の凹条45は、細長い溝であって、前記２本の凸条44の間隔と同じ間隔を空けて平行に形成されており、さらには、前記２本の凸条44とそれぞれ嵌合可能に形成されている。
そして、第１のログ材40の上に、第１のログ材40に対して交差させて、第２のログ材40を載せる。このとき、第１のログ材40のノッチ部42の上側と、第２のログ材40のノッチ部42の下側とが、互いに嵌り合うようにする。さらに、第２のログ材40の上に、第２のログ材40に対して交差させて、第３のログ材40を載せる。このとき、第２のログ材40のノッチ部42の上側と、第３のログ材40のノッチ部42の下側とが、互いに嵌り合うようにし、同時に、第１のログ材40の上に、第１のログ材40と平行に、第３のログ材40が積み重なるようにし、さらに、第１のログ材40の上面に設けた各凸条44と、第３のログ材40の下面に設けた各凹条45とが、それぞれ互いに嵌り合うようにする。さらに、第３のログ材40の上に、第３のログ材40に対して交差させて、第４のログ材40を載せる。このとき、第３のログ材40のノッチ部42の上側と、第４のログ材40のノッチ部42の下側とが、互いに嵌り合うようにし、同時に、第２のログ材40の上に、第２のログ材40と平行に、第４のログ材40が積み重なるようにし、さらに、第２のログ材40の上面に設けた各凸条44と、第４のログ材40の下面に設けた各凹条45とが、それぞれ互いに嵌り合うようにする。
Further, on the lower surface of each log member 40, two concave strips 45 extending from one end portion on the small edge 41 side to the other end portion on the small edge 41 side are provided. These two ridges 45 are elongated grooves, and are formed in parallel with the same interval as the interval between the two ridges 44, and are fitted into the two ridges 44, respectively. It is formed to be compatible.
Then, the second log material 40 is placed on the first log material 40 so as to intersect the first log material 40. At this time, the upper side of the notch portion 42 of the first log member 40 and the lower side of the notch portion 42 of the second log member 40 are fitted to each other. Further, the third log material 40 is placed on the second log material 40 so as to intersect the second log material 40. At this time, the upper side of the notch portion 42 of the second log member 40 and the lower side of the notch portion 42 of the third log member 40 are fitted to each other, and at the same time on the first log member 40. The third log material 40 is stacked in parallel with the first log material 40, and each protrusion 44 provided on the upper surface of the first log material 40 and the lower surface of the third log material 40 are arranged. The provided concave strips 45 are fitted with each other. Further, the fourth log material 40 is placed on the third log material 40 so as to intersect the third log material 40. At this time, the upper side of the notch portion 42 of the third log member 40 and the lower side of the notch portion 42 of the fourth log member 40 are fitted to each other, and at the same time on the second log member 40. The fourth log material 40 is stacked in parallel with the second log material 40, and the protrusions 44 provided on the upper surface of the second log material 40 are arranged on the lower surface of the fourth log material 40. The provided concave strips 45 are fitted with each other.
このようにして、複数のログ材40を交互に交差させながら積み重ねることにより、ログ壁30が構築される。
そして、第１のログ材40のノッチ部42の上側と、第２のログ材40のノッチ部42の下側とが、互いに嵌り合い、また、第２のログ材40のノッチ部42の上側と、第３のログ材40のノッチ部42の下側とが、互いに嵌り合うが、このように、交差する２本のログ材40における、互いに嵌り合う部分が、「ログ材40同士の交差部」である。
また、第１のログ材40の上に、第１のログ材40と平行に、第３のログ材40が積み重なり、また、第２のログ材40の上に、第２のログ材40と平行に、第４のログ材40が積み重なるが、このように、上下に重なり合う、２本の平行なログ材40が、「重なり合うログ材40同士」である。
In this way, the log wall 30 is constructed by stacking a plurality of log members 40 while alternately intersecting.
Then, the upper side of the notch portion 42 of the first log material 40 and the lower side of the notch portion 42 of the second log material 40 fit each other, and the upper side of the notch portion 42 of the second log material 40. And the lower side of the notch portion 42 of the third log member 40 are fitted to each other. Thus, the portions of the two log members 40 that intersect with each other are “intersection of the log members 40”. Part ".
In addition, a third log material 40 is stacked on the first log material 40 in parallel with the first log material 40, and the second log material 40 is formed on the second log material 40. The fourth log members 40 are stacked in parallel. In this way, the two parallel log members 40 that overlap vertically are “the overlapping log members 40”.
（防水部材50）
各ログ材40の小口41側端部近傍を除き、一のログ材40の上面の各凸条44と、その上に積み重ねられたログ材40の下面の各凹条45との間には、それぞれ防水部材50が介装されている。
ここで、防水部材50としては、テープ状のものを用いることができる。
そして、一のログ材40の上面の各凸条44の上に、この各凸条44に沿って防水部材50を貼り付け、その後に、その上に、他のログ材40を積み重ねる。そうすると、一のログ材40の上面の各凸条44と、その上に積み重ねられたログ材40の下面の各凹条45との間に、それぞれ防水部材50が介装されることとなる。
(Waterproof material 50)
Except for the vicinity of the edge 41 side end of each log material 40, between each convex strip 44 on the upper surface of one log material 40 and each concave strip 45 on the lower surface of the log material 40 stacked thereon, Waterproof members 50 are respectively interposed.
Here, as the waterproof member 50, a tape-shaped member can be used.
And the waterproof member 50 is affixed on each protruding item | line 44 of the upper surface of the one log member 40 along this each protruding item | line 44, Then, the other log member 40 is piled up on it. Then, the waterproof member 50 is interposed between each protrusion 44 on the upper surface of one log member 40 and each recess 45 on the lower surface of the log member 40 stacked thereon.
またここで、各凸条44の上に防水部材50を貼り付ける際には、小口41側端部の手前数センチメートルのところで、防水部材50を切る。このようにして、小口41側端部近傍には、防水部材50を介装しないようにする。
仮に小口41側端部に至るまで防水部材50を介装すると、ログ材40の小口41側から防水部材50の端部が見えてしまい、ログ壁30の見栄えが悪くなってしまうところ、小口41側端部の手前数センチメートルのところで防水部材50を切って、小口41側端部近傍には防水部材50を介装しないようにすると、ログ材40の小口41側から防水部材50が見えなくなり、ログ壁30の見栄えを良くすることができる。
Further, here, when the waterproof member 50 is pasted on each ridge 44, the waterproof member 50 is cut at a few centimeters before the end portion on the side of the fore edge 41. In this way, the waterproof member 50 is not interposed in the vicinity of the end portion on the side of the fore edge 41.
If the waterproof member 50 is interposed up to the end of the small edge 41, the end of the waterproof member 50 can be seen from the small edge 41 side of the log member 40, and the appearance of the log wall 30 is deteriorated. If the waterproofing member 50 is cut at a few centimeters in front of the side end portion and the waterproofing member 50 is not interposed near the end portion on the side of the small edge 41, the waterproofing member 50 becomes invisible from the small edge 41 side of the log material 40. The appearance of the log wall 30 can be improved.
そして、防水部材50が介装される部分と、防水部材50が介装されない部分との境界が、「防水境界60」である。
（排水孔70）
各ログ材40のノッチエンド部43には、上面から下面まで貫通する排水孔70が設けられている。
また、排水孔70は、防水境界60よりもログ材40同士の交差部側の位置に設けられている。つまり、排水孔70は、防水境界60よりもノッチ部42寄りの位置に設けられている。
また、排水孔70は、２本の凸条44の間に設けられ、さらに、排水孔70の直径は、２本の凸条44の間隔とほぼ等しくされている。
The boundary between the portion where the waterproof member 50 is interposed and the portion where the waterproof member 50 is not interposed is the “waterproof boundary 60”.
(Drain hole 70)
The notch end portion 43 of each log member 40 is provided with a drain hole 70 penetrating from the upper surface to the lower surface.
Further, the drain hole 70 is provided at a position closer to the crossing portion between the log members 40 than the waterproof boundary 60. That is, the drain hole 70 is provided at a position closer to the notch portion 42 than the waterproof boundary 60.
The drain hole 70 is provided between the two ridges 44, and the diameter of the drain hole 70 is substantially equal to the interval between the two ridges 44.
これにより、複数のログ材40を交互に交差させながら積み重ねてログ壁30を構築すると、ログ壁30における、各ログ材40の小口41側端部からログ材40同士の交差部までの間の所定位置に、最上段のログ材40の上面から最下段のログ材40の下面まで貫通し、かつ、重なり合うログ材40同士の間隙に浸入した水が下方へ抜ける、排水孔70が設けられることとなる。
なお、図１に示すように、本実施の形態では、ノッチエンド部43（各ログ材40における、小口41側端部からノッチ部42（他のログ材40との交差部）までの間の部分）は、基礎10や土台20よりも外側に突出している。このため、ノッチエンド部43の下方には、基礎10や土台20はない。これにより、排水孔70を伝って流下してきた雨水は、ログ壁30の外部へ速やかに排出されて、地面に落下するようになっている。
As a result, when the log wall 30 is constructed by stacking a plurality of log materials 40 alternately intersecting, the log wall 30 between the end portion of each log material 40 from the edge 41 side to the intersection of the log materials 40 A drain hole 70 is provided at a predetermined position so that water penetrating from the upper surface of the uppermost log member 40 to the lower surface of the lowermost log member 40 and allowing water that has entered the gap between the overlapping log members 40 to escape downward. It becomes.
As shown in FIG. 1, in the present embodiment, the notch end portion 43 (between each log member 40 and the notch 41 side end portion to the notch portion 42 (intersection with another log member 40)). Part) protrudes outside the foundation 10 and the base 20. For this reason, there is no foundation 10 or base 20 below the notch end portion 43. As a result, the rainwater flowing down through the drain hole 70 is quickly discharged to the outside of the log wall 30 and falls to the ground.
（作用・効果）
以上説明したように、本実施の形態では、ログ壁30における、各ログ材40の小口41側端部からログ材40同士の交差部までの間の所定位置に、最上段のログ材40の上面から最下段のログ材40の下面まで貫通する排水孔70を設けている。このため、ログ材40の小口41側からログ材40同士の間隙に浸入してしまった雨水を、この排水孔70を介して、ログ壁30の外部へ排出できる。
つまり、本実施の形態では、一のログ材40の上面の各凸条44と、その上に積み重ねられたログ材40の下面の各凹条45との間に、防水部材50を介装させているため、ログ壁30の室外側から室内側へ向けては、雨水が浸入しにくくなっているが、ログ材40の小口41側からログ材40同士の間隙へは、雨水が浸入し得るところ、上述した排水孔70を設けることにより、ログ材40の小口41側からログ材40同士の間隙に浸入してしまった雨水を、この排水孔70を介して下方へ落として、ログ壁30の外部へ排出できるのである。
(Action / Effect)
As described above, in the present embodiment, in the log wall 30, the uppermost log material 40 is located at a predetermined position between the end portion of each log material 40 on the small edge 41 side and the intersection of the log materials 40. A drain hole 70 penetrating from the upper surface to the lower surface of the lowermost log member 40 is provided. For this reason, rainwater that has entered the gap between the log members 40 from the small opening 41 side of the log member 40 can be discharged to the outside of the log wall 30 through the drain hole 70.
In other words, in the present embodiment, the waterproof member 50 is interposed between each protrusion 44 on the upper surface of one log member 40 and each recess 45 on the lower surface of the log member 40 stacked thereon. Therefore, it is difficult for rainwater to enter from the outdoor side of the log wall 30 to the indoor side, but rainwater can enter the gap between the log members 40 from the small mouth 41 side of the log member 40. However, by providing the drain hole 70 described above, the rainwater that has entered the gap between the log members 40 from the small opening 41 side of the log member 40 is dropped downward through the drain hole 70, and the log wall 30. Can be discharged to the outside.
また、本実施の形態では、ログ材40上面の２本の凸条44の間に、２本の凸条44の間隔とほぼ等しい直径の排水孔70を設けたことから、ログ材40の小口41側からログ材40同士の間隙に浸入してしまった雨水を、排水孔70よりもノッチ側へ伝わらせることなく、ログ壁30の外部へほぼ確実に排出できるのである。
さらに、本実施の形態では、各ログ材40の小口41側端部近傍を除き、一のログ材40の上面に設けた凸条44と、その上に積み重ねられたログ材40の下面に設けた、前記凸条44と嵌合する凹条45との間に、防水部材50を介装したことから、各ログ材40の小口41側から防水部材50が見えないので、ログ壁30の見栄えを良くすることができ、その上、防水部材50が介装される部分とされない部分との境界である防水境界60よりもログ材40同士の交差部側の位置に、排水孔70を設けたことから、防水部材50が介装されない部分を設けたことによりログ材40同士の間隙に浸入してしまった雨水をも、ログ壁30の外部へほぼ確実に排出できるのである。
In the present embodiment, since the drain hole 70 having a diameter substantially equal to the interval between the two ridges 44 is provided between the two ridges 44 on the upper surface of the log member 40, Rainwater that has entered the gap between the log members 40 from the 41 side can be discharged almost reliably to the outside of the log wall 30 without being transmitted to the notch side from the drain hole 70.
Further, in the present embodiment, except for the vicinity of the edge portion 41 side end of each log member 40, the protrusion 44 provided on the upper surface of one log member 40 and the lower surface of the log member 40 stacked thereon are provided. In addition, since the waterproof member 50 is interposed between the convex strip 44 and the concave strip 45 to be fitted, the waterproof member 50 cannot be seen from the small edge 41 side of each log member 40. In addition, a drain hole 70 is provided at a position closer to the intersection of the log members 40 than the waterproof boundary 60, which is a boundary between a portion where the waterproof member 50 is interposed and a portion where the waterproof member 50 is not interposed. For this reason, the rainwater that has entered the gap between the log members 40 due to the provision of the portion where the waterproof member 50 is not interposed can be almost certainly discharged to the outside of the log wall 30.
なお、上記実施の形態では、排水孔70は、最上段のログ材40の上面から最下段のログ材40の下面まで貫通させたが、これに限られるものではない。
例えば、屋根の形状等により、最上段のログ材40と上から２段目のログ材40には雨水がかからず、上から３段目以下のログ材40に雨水がかかるとする。このような場合には、排水孔70は、上から３段目のログ材40の上面から最下段のログ材40の下面まで貫通させればよい。このようにしても、ログ材40の小口41側からログ材40同士の間隙に浸入してしまった雨水を、排水孔70を介してログ壁30の外部へ排出するのに十分である。
つまり、排水孔70は、多段に積み重ねられているうちのいずれかのログ材40の上面から最下段のログ材40の下面まで貫通させればよい。
In the above embodiment, the drain hole 70 is penetrated from the upper surface of the uppermost log member 40 to the lower surface of the lowermost log member 40, but the present invention is not limited to this.
For example, it is assumed that due to the shape of the roof, the uppermost log material 40 and the second log material 40 from the top are not subject to rainwater, and the third or lower log material 40 from the top is subject to rainwater. In such a case, the drain hole 70 may be penetrated from the upper surface of the third log material 40 from the top to the lower surface of the lowermost log material 40. Even in this case, it is sufficient to discharge the rainwater that has entered the gap between the log members 40 from the small mouth 41 side of the log member 40 to the outside of the log wall 30 through the drain hole 70.
That is, the drain hole 70 may be penetrated from the upper surface of any one of the log members 40 stacked in multiple stages to the lower surface of the lowermost log member 40.
また、排水孔70を「いずれのログ材40」の上面からにするかは、最上段から最下段までのログ材40の中から、雨水がかかるか否かにより、適宜選択することができる。
（他の実施の形態）
また、図示しないが、各ログ材40のノッチエンド部43の上面であって２本の凸条44の間に、排水孔70へ向けて高さが次第に低くなるように傾斜した面である、排水傾斜面を設けることができる。
そうすると、ログ材40の小口41側からログ材40同士の間隙に浸入してしまった雨水を、排水孔70へ誘導しやすくすることができ、ひいてはログ壁30の外部へ排出しやすくすることができるのである。
The drain hole 70 can be selected as appropriate depending on whether rainwater is applied or not from among the log materials 40 from the top to the bottom.

In addition, although not shown in the drawing, it is a top surface of the notch end portion 43 of each log member 40 and is a surface that is inclined so that the height gradually decreases toward the drain hole 70 between the two ridges 44. A drain slope can be provided.
Then, the rainwater that has entered the gap between the log members 40 from the small mouth 41 side of the log member 40 can be easily guided to the drain hole 70, and can be easily discharged to the outside of the log wall 30. It can be done.
また、図示しないが、各ログ材40のノッチエンド部43の上面であって２本の凸条44の間に、排水孔70へ向けて高さが次第に低くなるように傾斜した溝である、排水傾斜溝を設けることができる。
そうすると、ログ材40の小口41側からログ材40同士の間隙に浸入してしまった雨水を、排水孔70へ誘導しやすくすることができ、ひいてはログ壁30の外部へ排出しやすくすることができるのである。
なお、排水傾斜面を設けることなく、排水傾斜溝を設けてもよく、また、排水傾斜面を設けた上で、排水傾斜溝を設けてもよい。
Further, although not shown, it is a groove that is inclined on the upper surface of the notch end portion 43 of each log member 40 and between the two ridges 44 so that the height gradually decreases toward the drain hole 70. A drainage inclined groove can be provided.
Then, the rainwater that has entered the gap between the log members 40 from the small mouth 41 side of the log member 40 can be easily guided to the drain hole 70, and can be easily discharged to the outside of the log wall 30. It can be done.
In addition, a drainage inclined groove may be provided without providing a drainage inclined surface, and a drainage inclined groove may be provided after providing a drainage inclined surface.
