Description

壁面構造体、及び、建物Wall structure and building
 本発明は、壁面構造体、及び、建物に関する。更に詳しくは、外壁部分の少なくとも一部にログ壁を使用することで炭素貯蔵効果及び省エネルギー効果を奏し、新築時におけるログ壁の施工を容易にすると共に、経年によるログ材の乾燥収縮で水平に積んだ各段の間に隙間が生じる現象(以下「ログ材の収縮現象」という)が生じた際に、ログ材間の隙間調整を容易に行うことができる、壁面構造体、及び、建物を提供することを目的とする。 The present invention relates to a wall structure and a building. More specifically, by using a log wall for at least a part of the outer wall part, a carbon storage effect and an energy saving effect can be achieved, facilitating the construction of the log wall at the time of new construction, and horizontally due to the drying shrinkage of the log material over time. A wall structure and a building that can easily adjust the gap between log materials when a gap occurs between each stacked stage (hereinafter referred to as "log material shrinkage phenomenon"). The purpose is to provide.
 近年、耐震性向上のため、建物の躯体に耐力構造体を使用するケースが増えている。主な耐力構造体としては、鉄骨を用いるケース(いわゆる鉄骨造であり、軽量鉄骨造及び重量鉄骨造のいずれも含む意味で使用する。以下「鉄骨造」という)や、鉄筋コンクリート等が挙げられる。 In recent years, in order to improve earthquake resistance, the number of cases where load-bearing structures are used for the building frame is increasing. Examples of the main load-bearing structure include a case using a steel frame (so-called steel structure, which is used in the sense of including both a lightweight steel structure and a heavy steel structure; hereinafter referred to as “steel structure”), reinforced concrete, and the like.
 しかしながら、材料となる鉄骨や鉄筋、コンクリートの原料となるセメントは、その製造にあたって二酸化炭素を多く排出し、エネルギーを多く消費する。この課題に対し、本発明者は、外壁部分の構造材として木材に着目し、外壁部分の少なくとも一部にログ壁を使用する構造を想到した。 However, steel frames and reinforcing bars, which are the materials, and cement, which is the raw material for concrete, emit a lot of carbon dioxide and consume a lot of energy in their production. In response to this problem, the present inventor focused on wood as a structural material for the outer wall portion, and came up with a structure in which a log wall is used for at least a part of the outer wall portion.
 建物の外壁としてログ壁を構築する技術の一例として、特許文献1に示すような発明が提案されている。特許文献1記載の発明によれば、通しボルトにより地震力や風圧力に起因するログ壁の引抜力を十分に拘束し、ログ壁の回転を抑えることで、剛性が増したログ壁を提供することができるとされている。 An invention as shown in Patent Document 1 has been proposed as an example of a technique for constructing a log wall as an outer wall of a building. According to the invention described in Patent Document 1, a log wall having increased rigidity is provided by sufficiently restraining the pulling force of the log wall caused by seismic force and wind pressure by a through bolt and suppressing the rotation of the log wall. It is said that it can be done.

 ところで、ログ壁は、経年によるログ材の収縮現象が生じるため、収縮後の各ログ材の間に生じた隙間を詰める調整作業(以下「ログ材間の隙間調整」という)が必要であるが、特許文献1では、このような課題の解決手段が開示されていない。 By the way, since the log wall shrinks due to aging, it is necessary to perform adjustment work (hereinafter referred to as "gap adjustment between log materials") to close the gap generated between each log material after shrinkage. , Patent Document 1 does not disclose a means for solving such a problem.
 また、特許文献1には明示されていないが、一般的にログ壁を構築する際に、桁や屋根あるいは軒等と、ログ壁の最上段に配置したログ材の上部との間に、隙間が形成され、この前述の隙間をコーキング材等で埋めるような作業を要する場合が多い。 Further, although not specified in Patent Document 1, generally, when constructing a log wall, there is a gap between a girder, a roof, an eave, etc. and an upper part of a log material arranged at the uppermost stage of the log wall. Is formed, and it is often necessary to fill the above-mentioned gap with a caulking material or the like.
 一方、昨今、建築分野における熟練工が不足傾向にあり、本来ある程度の熟練を要する作業であるコーキング作業を行うためには、熟練工による着手の順番を待つか、又は、熟練工ではない者が作業を担当することになる。しかしながら、熟練工の順番を待つ場合は工期の遅れに繋がり、熟練工ではない者が作業を担当した場合も工期の遅れが予期され、加えて、十分な作業品質が確保されないおそれもある。 On the other hand, in recent years, there is a tendency for skilled workers in the construction field to be in short supply, and in order to perform caulking work, which is a work that originally requires a certain amount of skill, either wait for the turn of skilled workers to start, or a person who is not a skilled worker is in charge of the work. Will be done. However, waiting for the turn of skilled workers leads to a delay in the construction period, and even if a person who is not a skilled worker is in charge of the work, the delay in the construction period is expected, and in addition, sufficient work quality may not be ensured.
 本発明は、以上の点を鑑みて創案されたものであり、外壁部分の少なくとも一部にログ壁を使用することで炭素貯蔵効果及び省エネルギー効果を奏し、新築時におけるログ壁の施工を容易にすると共に、経年によるログ材の収縮現象が生じた際にログ材間の隙間調整を容易に行うことができる、壁面構造体、及び、建物を提供することを目的とする。 The present invention was devised in view of the above points, and by using a log wall for at least a part of the outer wall portion, a carbon storage effect and an energy saving effect can be obtained, and the construction of the log wall at the time of new construction can be facilitated. At the same time, it is an object of the present invention to provide a wall surface structure and a building capable of easily adjusting the gap between log materials when a shrinkage phenomenon of log materials occurs due to aging.
 上記の目的を達成するために本発明の壁面構造体は、設置基部と、該設置基部から屋根あるいは上階の床レベルの高さの間に配置され、ログ壁である部分を含む外壁と、該外壁に係る前記ログ壁の間隔を調整可能なログ壁調整部とを備え、前記設置基部が、所定の高さで立設された壁状部を有し、該壁状部は、その高さ方向中間の領域に、建物外に向けて開口した開口部又は開放された開放部が形成されていると共に、一端が前記壁状部の上部に開口し、他端が前記開口部内又は前記開放部内に開口した第1貫通孔が形成されており、前記外壁が、その一部又は全部の領域が、長軸方向が略水平となるように横設した複数のログ材を積重してなる構造であり、最上段に位置する前記ログ材の上面から最下段に位置する前記ログ材の下面に至る第2貫通孔が、前記第1貫通孔と連通する配置で形成されたログ壁部、及び、該ログ壁部の最上段に配置されたログ材の上部に取り付けられた断熱性を有する中間部材、を有し、前記ログ壁調整部が、少なくとも、前記第1貫通孔とこれに連通した前記第2貫通孔とに通した挿通状態で、該第1貫通孔の他端側開口から雄ネジ部が所定長さで露出する長さに設けられた緊結ボルト、及び、同第1貫通孔の他端側開口から露出した雄ネジ部に締結されたナット、を有する構造である。 In order to achieve the above object, the wall structure of the present invention is arranged between the installation base and the floor level height of the roof or the upper floor from the installation base, and includes an outer wall including a portion which is a log wall. The log wall adjusting portion for adjusting the interval of the log wall related to the outer wall is provided, the installation base portion has a wall-shaped portion erected at a predetermined height, and the wall-shaped portion has a height thereof. An opening or an open opening that opens toward the outside of the building is formed in the region in the middle in the horizontal direction, and one end opens to the upper part of the wall-shaped portion and the other end is inside the opening or the opening. A first through hole opened in the portion is formed, and the outer wall is formed by stacking a plurality of log materials horizontally arranged so that a part or all of the area thereof is substantially horizontal in the long axis direction. A log wall portion having a structure in which a second through hole extending from an upper surface of the log material located at the uppermost stage to a lower surface of the log material located at the lowermost stage communicates with the first through hole. And an intermediate member having heat insulating properties attached to the upper part of the log material arranged at the uppermost stage of the log wall portion, and the log wall adjusting portion communicates with at least the first through hole. A binding bolt provided at a length in which the male screw portion is exposed to a predetermined length from the opening on the other end side of the first through hole in the inserted state through the second through hole, and the first through hole. The structure has a nut fastened to a male screw portion exposed from the opening on the other end side of the hole.
 ここで、本発明の壁面構造体は、設置基部を備えることにより、その上部で前述した外壁下部を支持すると共に、ログ壁調整部の一部を設けることできる。壁状部は、前述の第1貫通孔が形成されていることにより、連通する第2貫通孔と共に、緊結ボルトを通すことができる。 Here, by providing the installation base portion, the wall surface structure of the present invention can support the lower part of the outer wall described above at the upper portion thereof and can provide a part of the log wall adjusting portion. Since the above-mentioned first through hole is formed in the wall-shaped portion, the fastening bolt can be passed through the wall-shaped portion together with the second through hole that communicates with the wall-shaped portion.
 なお、「設置基部」は、例えば、1階部分に本発明の壁面構造体を設置する態様にあっては、建物基礎が該当する。そして、1階部分等の階下部分がコンクリート構造体であり、上階部分に本発明の壁面構造体を設置する態様にあっては、同壁面構造体を設置する上階と下階の間に位置する床スラブ部分が該当する。 The "installation base" corresponds to, for example, the building foundation in the embodiment in which the wall surface structure of the present invention is installed on the first floor. The lower floor portion such as the first floor portion is a concrete structure, and in the embodiment in which the wall surface structure of the present invention is installed on the upper floor portion, the wall surface structure is installed between the upper floor and the lower floor. This corresponds to the floor slab part where it is located.
 更に、壁状部は、前述の開口部又は開放部が形成されていることにより、第1貫通孔の他端から露出した雄ネジ部に対してナットを締結する作業を容易に行うことができる。そして、開口部又は開放部は、建物外に向けて開口した又は開放された構造であるため、建築して所定期間経過後にログ壁調整作業を行う際に、建物内に立ち入ることなく(換言すると建物外から直接)作業を行うことができるので、建物使用者のプライバシーを保つことができる。 Further, since the wall-shaped portion is formed with the above-mentioned opening or opening portion, the work of fastening the nut to the male screw portion exposed from the other end of the first through hole can be easily performed. .. Since the opening or opening has a structure that is open or open toward the outside of the building, when the log wall adjustment work is performed after the lapse of a predetermined period of construction, the building does not enter (in other words,). Since the work can be performed directly from outside the building, the privacy of the building user can be maintained.
 本発明の壁面構造体は、前述した外壁を備えることにより、建物における設置基部から屋根あるいは上階の床レベルの高さの領域(以下「屋根等までの領域」という)の外装を構成することができる。なお、本発明の壁面構造体は、平屋である場合は「屋根」、二階建て以上である場合は「上階の床レベル」に適用するものである。そして、用語「上階の床レベル」は、「上階の床を構成する水平面の高さ」の意味で使用しており、二階の床レベルであってもよいし、それ以上の階の床レベルであってもよい。 By providing the above-mentioned outer wall, the wall surface structure of the present invention constitutes the exterior of a region at the height of the roof or the floor of the upper floor (hereinafter referred to as "the region to the roof or the like") from the installation base in the building. Can be done. The wall structure of the present invention is applied to the "roof" in the case of a one-story building and the "floor level of the upper floor" in the case of two or more floors. The term "upper floor level" is used to mean "the height of the horizontal plane that constitutes the upper floor", and may be the floor level of the second floor or the floor of a higher floor. It may be a level.
 外壁は、前述した構造のログ壁部を有することにより、建物外観あるいは内観の審美性を向上させることができる。なお、ログ壁部は、外壁の全部の領域に配設された態様であってもよいし、外壁の一部の領域に配設され、他の領域には外壁パネルや窓を配置した態様であってもよい。また、ログ壁部は、前述の第2貫通孔が形成されていることにより、連通する第1貫通孔と共に、緊結ボルトを通すことができる。 By having the log wall portion of the structure described above, the outer wall can improve the aesthetics of the exterior or interior of the building. The log wall portion may be arranged in the entire area of the outer wall, or may be arranged in a part of the outer wall, and the outer wall panel or the window may be arranged in the other area. There may be. Further, since the above-mentioned second through hole is formed in the log wall portion, the binding bolt can be passed through the log wall portion together with the first through hole that communicates with the log wall portion.
 加えて、木材であるログ材を使用したことにより、(a)木材中の炭素を長期間にわたって貯蔵することに繋がる(炭素貯蔵効果)と共に、(b)鉄等の建材と比較して、製造・加工時(以下「製造等」という)に要するエネルギーが少なく、製造等に要する二酸化炭素の排出量が抑制され(省エネルギー効果)、(a)及び(b)の効果を以て、地球温暖化防止、温室効果ガス排出削減に寄与することができる。 In addition, the use of log material, which is wood, leads to (a) long-term storage of carbon in wood (carbon storage effect), and (b) production compared to building materials such as iron. -The energy required during processing (hereinafter referred to as "manufacturing, etc.") is small, the amount of carbon dioxide emissions required for manufacturing, etc. is suppressed (energy saving effect), and the effects of (a) and (b) prevent global warming. It can contribute to the reduction of greenhouse gas emissions.
 前述のログ材は、例えば、いわゆる丸ログ、Dログ、あるいは角ログ等といわれる形状のものが挙げられるが、特に限定するものではなく、また、ハンドカットあるいはマシンカット等のいずれであってもよい。 Examples of the above-mentioned log material include so-called round logs, D logs, square logs, and the like, but the log material is not particularly limited, and may be hand-cut or machine-cut. good.
 中間部材は、屋根あるいは上階の床レベルの下部(以下「屋根等の下部」という)とログ壁部の最上段の間の隙間を塞ぎ、建物内への外気の流入を抑制することができる。なお、中間部材は、例えば、前述した外壁の一部の領域にログ壁部が配設された態様にあっては、外壁パネルや窓等の区画部材の下部と、ログ壁部の最上段の間に配置される。 The intermediate member can close the gap between the lower part of the roof or the upper floor level (hereinafter referred to as "the lower part of the roof, etc.") and the uppermost part of the log wall, and suppress the inflow of outside air into the building. .. The intermediate member is, for example, in the above-described embodiment in which the log wall portion is arranged in a part of the outer wall, the lower portion of the partition member such as the outer wall panel or the window, and the uppermost stage of the log wall portion. Placed in between.
 加えて、中間部材は、その設置が最上段に配置したログ材の上部に取り付けるだけでよいため、前述の隙間をコーキング材等で埋めるような施工方法と比較して、施工を簡易且つ速やかに行うことができる。ところで、前述の隙間をコーキング材等で埋めるような施工方法は、本来ある程度の熟練を要する作業であったが、前述の中間部材によれば、予め製造された部材を使用して取り付ける作業のみで済むため、熟練した作業者でなくとも(作業者の能力に影響されることなく)容易に行うことができ、昨今の熟練工不足にも対応したものとなっている。 In addition, since the intermediate member only needs to be installed on the upper part of the log material arranged at the uppermost stage, the construction is simpler and faster than the above-mentioned construction method in which the gap is filled with caulking material or the like. It can be carried out. By the way, the above-mentioned construction method of filling the gap with a caulking material or the like originally required a certain amount of skill, but according to the above-mentioned intermediate member, only the work of attaching using a pre-manufactured member is required. Therefore, it can be easily performed even by a non-skilled worker (without being affected by the ability of the worker), and it corresponds to the recent shortage of skilled workers.
 ログ壁調整部は、各ログ材の結合状態を保持すると共に、ログ材の収縮現象が生じたとしても、ログ材の隙間を調整することができる。そして、ログ壁調整部は、緊結ボルト及びナットを有することにより、前述の第1貫通孔とこれに連通した第2貫通孔に緊結ボルトを挿通させ、第1貫通孔の他端側開口から露出した緊結ボルトの雄ネジ部にナットを締結することで、設置基部と外壁とを緊結することができる。 The log wall adjusting unit can maintain the bonded state of each log material and can adjust the gap of the log material even if the log material shrinks. Then, by having the binding bolt and the nut, the log wall adjusting portion allows the binding bolt to be inserted into the above-mentioned first through hole and the second through hole communicating with the first through hole, and is exposed from the other end opening of the first through hole. By fastening the nut to the male screw portion of the tightening bolt, the installation base and the outer wall can be fastened.
 緊結ボルトは、少なくとも雄ネジ部が設けられた先端が第1貫通孔から露出する構造であればよく、例えば、他端は雄ネジ部を設けて他のナット(ワッシャーを組み合わせてもよい)を締結する構造や、L字状に屈曲させて屈曲部を最上段に位置するログ材の上面に掛止する構造等であってもよい。また、ナットとしては、一般的なナットが挙げられるが、これに限定するものではなく、例えば、ダブルナット構造(ワッシャーを組み合わせてもよい)や、増し締めが可能で緩み止め機能を有する特殊ナット等であってもよい。 The tightening bolt may have a structure in which at least the tip provided with the male screw portion is exposed from the first through hole. For example, the other end may be provided with a male screw portion and another nut (a washer may be combined). It may be a structure to be fastened, a structure to be bent in an L shape, and a structure in which the bent portion is hooked on the upper surface of the log material located at the uppermost stage. The nut includes, but is not limited to, a general nut, for example, a double nut structure (a washer may be combined) or a special nut that can be retightened and has a loosening prevention function. And so on.
 また、外壁が、中間部材の上部から屋根あるいは上階の床レベルの高さの間の領域に設けられ、建物内外に区画する板状の区画壁部を有する場合は、ログ壁部よりも上方である前述の領域を建物内外に区画し、外壁の一部を構成することができる。この場合、前述した中間部材は、ログ壁部と区画壁部の間に配置されることになり、ログ壁部と区画壁部の隙間を埋めて、建物内への外気の流入を抑制することになる。 Further, when the outer wall is provided in the area between the upper part of the intermediate member and the floor level height of the roof or the upper floor and has a plate-shaped partition wall portion for partitioning inside and outside the building, the outer wall is above the log wall portion. The above-mentioned area is divided into the inside and outside of the building, and a part of the outer wall can be formed. In this case, the above-mentioned intermediate member is arranged between the log wall portion and the partition wall portion, and fills the gap between the log wall portion and the partition wall portion to suppress the inflow of outside air into the building. become.
 更に、区画壁部は、板状であることにより、設置基部から屋根等までの領域が全面ログ壁である外壁と比較して、外壁の構造重量を軽減することができ、これによって建物上部の構造重量が軽減され、耐震性が向上した構造となる。なお、区画壁部は、板状であればその構造を特に限定するものではなく、例えば、サイディングボード等のパネル外壁材が挙げられると共に、高窓(ハイサイドライト)を区画壁部の一部又は全面として配置してもよい。 Further, since the partition wall portion has a plate shape, the structural weight of the outer wall can be reduced as compared with the outer wall in which the area from the installation base to the roof etc. is the entire log wall, whereby the structural weight of the outer wall can be reduced. The structure weight is reduced and the structure has improved earthquake resistance. The structure of the partition wall portion is not particularly limited as long as it is plate-shaped. For example, a panel outer wall material such as a siding board may be used, and a high window (high side light) may be a part of the partition wall portion. Alternatively, it may be arranged as the entire surface.
 また、壁面構造体が、建物において外壁よりも屋内側に配置される耐力構造体に接続可能な接続体を更に備える場合は、接続体を介して壁面構造体と耐力構造体に接続することができる。なお、本発明の外壁部分は必ずしも耐力壁ではないが、この接続体によって壁面構造と耐力構造体が容易に脱離しない態様で接続され、耐震性が付加された構造となる。なお、用語「耐力構造体」は、少なくとも鉛直荷重に対する耐力を有するものであり、水平荷重に対する耐力を有することが更に好ましく、鉄骨や鉄筋コンクリート等の柱体、又は、鉄筋コンクリート等の耐力壁、その他の耐力性を有する構造物を含む意味で使用している。 Further, when the wall surface structure further includes a connection body that can be connected to the load-bearing structure arranged on the indoor side of the outer wall in the building, it may be connected to the wall surface structure and the load-bearing structure via the connecting body. can. The outer wall portion of the present invention is not necessarily a load-bearing wall, but the wall structure and the load-bearing structure are connected by this connecting body in such a manner that they are not easily detached to form a structure to which earthquake resistance is added. The term "bearing structure" has at least a bearing capacity against a vertical load, and more preferably has a bearing capacity against a horizontal load, such as a pillar body such as a steel frame or a reinforced concrete, a bearing wall such as a reinforced concrete, or the like. It is used in the sense that it includes a structure with bearing capacity.
 また、中間部材が、下方が開口した逆溝形であり、溝内が最上段に位置するログ材の上面及び側部に沿う形状に設けられている場合は、予め製造された中間部材を使用し、最上段に配置したログ材の上部に被せるだけで設置が済むため、非熟練作業者であっても、施工を簡易且つ更に速やかで正確に行うことができる。 If the intermediate member has an inverted groove shape with an opening at the bottom and the inside of the groove is provided along the upper surface and side of the log material located at the uppermost stage, a pre-manufactured intermediate member is used. However, since the installation is completed simply by covering the top of the log material arranged at the top, even an unskilled worker can perform the construction easily, more quickly and accurately.
 また、外壁が、建物の屋内を向いた側に配設された背板部を有し、背板部は、ログ壁部上部の方向へ所定長さを以て垂下した垂下部分を含む構造である場合は、ログ材の収縮現象が生じてログ材の隙間を調整した際に、垂下部分によりログ壁部上端とその上部にある構造材下端の間に生じる隙間を塞ぐことができる。なお、「ログ壁部の上部にある構造材」としては、軒桁や前述した区画壁部が挙げられる。 Further, when the outer wall has a back plate portion arranged on the side facing the inside of the building, and the back plate portion has a structure including a hanging portion that hangs down with a predetermined length in the direction of the upper part of the log wall portion. Can close the gap generated between the upper end of the log wall portion and the lower end of the structural material above the log wall portion by the hanging portion when the shrinkage phenomenon of the log material occurs and the gap of the log material is adjusted. Examples of the "structural material above the log wall portion" include eaves girders and the above-mentioned partition wall portion.
 詳しくは、本発明の壁面構造体は、ログ材の収縮現象が生じた際に、ログ壁調整部のナットを増し締めすることで設置基部と外壁とが再緊結され、ログ材の間が詰まって隙間が埋まる構造であるが、ログ材の隙間を調整すると、ログ壁部の高さが低くなり、ログ壁部上端とその上部にある構造材下端の間に、新たな隙間が生じることになる。しかしながら、前述の背板部を有する場合は、前述した垂下した垂下部分によって、中間部材の交換やシーリング材の充填の作業を要することなく、建物の屋内を向いた側からこの新たな隙間を塞ぐことができる。 Specifically, in the wall surface structure of the present invention, when the log material shrinks, the installation base and the outer wall are re-tightened by tightening the nut of the log wall adjusting portion, and the space between the log materials is clogged. However, if the gap between the log materials is adjusted, the height of the log wall will be lowered, and a new gap will be created between the upper end of the log wall and the lower end of the structural material above it. Become. However, when the above-mentioned back plate portion is provided, the above-mentioned hanging portion closes this new gap from the side facing the inside of the building without requiring replacement of the intermediate member or filling of the sealing material. be able to.
 なお、垂下部分の「所定長さ」は、ログ材の収縮現象による収縮量と積重したログ材の数から算出して設定することができる。 The "predetermined length" of the hanging portion can be set by calculating from the amount of shrinkage due to the shrinkage phenomenon of the log material and the number of stacked log materials.
 また、設置基部が、建物の基礎部分であり、前記壁状部が、地面から所定の高さで立設された地上部と、前記地上部の上端において建物外となる方向に張り出し、且つ、張り出した部分の下面が地面から所定高さを空けて設けられた張出部とを有し、該張出部に前記第1貫通孔が形成されている場合は、外壁を張出部の鉛直方向に設けることができる。なお、張出部の下面と地面との間の空間は、前述した「開放部」に相当する。 Further, the installation base is the foundation portion of the building, and the wall-shaped portion projects above the ground portion erected at a predetermined height from the ground and at the upper end of the above-ground portion in a direction outside the building. When the lower surface of the overhanging portion has an overhanging portion provided at a predetermined height from the ground and the first through hole is formed in the overhanging portion, the outer wall is vertically formed on the overhanging portion. Can be provided in the direction. The space between the lower surface of the overhanging portion and the ground corresponds to the above-mentioned "open portion".
 建物の基礎部分は、前述した構造の張出部により、地上部に開口部を形成する必要が無く、開口部の無い地上部は、開口部が形成された地上部よりも耐荷重性が向上している。また、建物の基礎部分は、前述した構造の地上部により、外壁下部を支持し、外壁下部と地面との間に所定の距離を確保することができる。更にまた、地上部は、前述の第1貫通孔が形成されていることにより、連通する第2貫通孔と共に、緊結ボルトを通すことができる。 It is not necessary to form an opening in the above-ground part of the foundation part of the building due to the overhanging part of the structure described above, and the above-ground part without the opening has improved load bearing capacity as compared with the above-ground part having the opening. doing. Further, the foundation portion of the building supports the lower part of the outer wall by the above-ground part of the above-mentioned structure, and a predetermined distance can be secured between the lower part of the outer wall and the ground. Furthermore, since the above-mentioned first through hole is formed in the above-ground portion, the binding bolt can be passed through together with the second through hole that communicates with the ground portion.
 そして、建物の基礎部分は、例えば、耐荷重性の高い地上部の鉛直方向に耐力構造体を設けることができ、この場合、建物の基礎部分は、その上に外壁と耐力構造体とが近接配置され、纏まりが良く、屋内空間も広く確保できる構造にすることができる。また、外壁と耐力構造体が近接配置されることで、接続体の長さを短くでき、地震等の横揺れ時に接続体に加わる応力を低減することができる。 Then, for example, the foundation portion of the building can be provided with a load-bearing structure in the vertical direction of the above-ground portion having high load bearing capacity. The structure can be arranged, well organized, and a large indoor space can be secured. Further, by arranging the outer wall and the load-bearing structure close to each other, the length of the connecting body can be shortened, and the stress applied to the connecting body at the time of rolling such as an earthquake can be reduced.
 また、外壁が、少なくとも前記ログ壁を覆う耐火壁部あるいは防火壁部を有する場合は、ログ壁部分に耐火性あるいは防火性を付与することができる。これにより、例えば、都市部等において、本発明の壁面構造体を適用する建物が、隣接する建物との距離が近い場合であっても、隣の建物に向いた側の壁面に耐火壁部を設けることによって、隣の建物が火災に遭ったとしても、木材であるログ壁が延焼しにくい構造となる。ここで、用語「防火」は、「耐火」よりも火熱を遮る時間が短い能力を意味している。また、用語「耐火」は、「耐火」以下「防火」以上の火熱を遮る「準耐火」能力を含む意味で使用している。 Further, when the outer wall has at least a fireproof wall portion or a fireproof wall portion covering the log wall, the log wall portion can be imparted with fire resistance or fire resistance. As a result, for example, in an urban area or the like, even if the building to which the wall structure of the present invention is applied is close to the adjacent building, the fireproof wall portion is provided on the wall surface facing the adjacent building. By providing it, even if the next building is hit by a fire, the log wall, which is made of wood, will not spread easily. Here, the term "fire protection" means the ability to block fire heat for a shorter period of time than "fire resistance". In addition, the term "fireproof" is used to include "quasi-fireproof" ability to block fire heat of "fireproof" or lower and "fireproof" or higher.
 上記の目的を達成するために本発明の壁面構造体は、設置基部と、該設置基部から屋根あるいは上階の床レベルの高さの間に配置され、少なくともその一部又は全部の領域が、長軸方向が略水平となるように横設した複数のログ材を積重してなる構造のログ壁部、及び、該ログ壁部の最上段に配置したログ材の上部に取り付けられ、上方が上部の構造物を受けるか又は該構造物と当接して同構造物との間を閉塞可能な形状であると共に、下方が開口した逆溝形で、溝内が最上段に位置する前記ログ材の上面及び側部に沿う形状に設けられ、断熱性を有する中間部材、を有する外壁と、該外壁に設けられ、牽引力を以て前記ログ壁の間隔を調整可能なログ壁調整部とを備える。 In order to achieve the above object, the wall structure of the present invention is arranged between the installation base and the floor level height of the roof or the upper floor from the installation base, and at least a part or all of the area thereof is.

Examples of the "installation base" include a building foundation on the first floor and a floor slab portion located between the upper and lower floors.
 本発明の壁面構造体は、前述した外壁を備えることにより、建物における設置基部から屋根等までの領域の外装を構成することができる。外壁は、前述したログ壁部を有することにより、建物外観の審美性を向上させることができる。なお、ログ壁部は、外壁の全部の領域に配設された態様であってもよいし、外壁の一部の領域に配設され、他の領域には外壁パネルや窓を配置した態様であってもよい。加えて、壁面構造体は、ログ材の使用により、炭素貯蔵効果、及び、製造等における省エネルギー効果を以て、地球温暖化防止、温室効果ガス排出削減に寄与することができる。 By providing the above-mentioned outer wall, the wall surface structure of the present invention can form the exterior of the area from the installation base to the roof or the like in the building.

The intermediate member is, for example, in the above-described embodiment in which the log wall portion is arranged in a part of the outer wall, the lower part of the partition member such as the outer wall panel or the window, which is the upper structure, and the log. It is placed between the tops of the wall and receives the upper structure. In addition, since the intermediate member only needs to be installed on the upper part of the log material arranged at the uppermost stage, it is not a skilled worker as compared with the above-mentioned construction method in which the gap is filled with caulking material or the like. In both cases, the construction can be carried out easily and quickly.
 ログ壁調整部は、牽引力を以て各ログ材の結合状態を保持すると共に、ログ材の収縮現象が生じたとしても、ログ材の隙間を調整することができる。なお、ログ壁調整部は、例えば、緊結ボルト及びナット(ターンバックル等を含む)の組み合わせであってもよい。 The log wall adjusting unit maintains the bonded state of each log material by traction force, and can adjust the gap of the log material even if the log material shrinks. The log wall adjusting unit may be, for example, a combination of a tightening bolt and a nut (including a turnbuckle and the like).

 <接続体3>
 接続体3は、建物1の屋内側に配置され、耐力構造体4に接続されている。接続体3は、L字型であり、水平部31と垂直部32を有する。なお、接続体3は、水平荷重の応力集中を回避する等の観点から、ログ壁部22の屋内側において、ログ壁部22の横幅方向に複数(図示省略)設置されている。
<Connector 3>
The connecting body 3 is arranged on the indoor side of the building 1 and is connected to the load-bearing structure 4. The connecting body 3 is L-shaped and has a horizontal portion 31 and a vertical portion 32. From the viewpoint of avoiding stress concentration of the horizontal load, a plurality of connecting bodies 3 are installed on the indoor side of the log wall portion 22 in the lateral width direction of the log wall portion 22 (not shown).
 水平部31は、接続体3の設置時(すなわち、外壁21と耐力構造体4との接続時)において、外壁21と耐力構造体4の間に位置する部分である。また、水平部31は、その先端近傍に孔311が形成されている。 The horizontal portion 31 is a portion located between the outer wall 21 and the load-bearing structure 4 when the connecting body 3 is installed (that is, when the outer wall 21 and the load-bearing structure 4 are connected). Further, the horizontal portion 31 has a hole 311 formed in the vicinity of the tip thereof.
 水平部31は、その先部を、ログ壁部22を構成する所定位置のログ材の間(上段と下段の間)に挟み、孔311に釘、ネジ、ボルト等の軸体を挿通させてログ材に固定し、ログ材の間から抜けないように固定されている。 The horizontal portion 31 has its tip sandwiched between log materials (between the upper and lower stages) at predetermined positions constituting the log wall portion 22, and a shaft body such as a nail, a screw, or a bolt is inserted into the hole 311. It is fixed to the log material and fixed so that it does not come off between the log materials.
 接続体3(の少なくとも一つ)は、ログ壁部22の第1貫通孔204が設けられた位置に合わせて設置している。このとき、同接続体3は、水平部31の孔311と第1貫通孔204の位置を合わせ、ここに緊結ボルト271を通すことでログ材の間から抜けないように固定される。 The connection body 3 (at least one) is installed according to the position where the first through hole 204 of the log wall portion 22 is provided. At this time, the connecting body 3 is fixed so as not to come out from between the log materials by aligning the positions of the holes 311 of the horizontal portion 31 and the first through holes 204 and passing the binding bolts 271 there.
 垂直部32は、接続体3の設置時(すなわち、外壁21と耐力構造体4との接続時)において、その高さ方向が耐力構造体4の高さ方向に沿って当接する部分である。また、垂直部32は、長孔321が形成されており、垂直部32の長手方向と、長孔321の長手方向は一致している。 The vertical portion 32 is a portion whose height direction abuts along the height direction of the load-bearing structure 4 when the connecting body 3 is installed (that is, when the outer wall 21 and the load-bearing structure 4 are connected). Further, the vertical portion 32 is formed with an elongated hole 321, and the longitudinal direction of the vertical portion 32 and the longitudinal direction of the elongated hole 321 coincide with each other.
 垂直部32は、耐力構造体4からの屋外方向に向けて突出した接続ボルト41を長孔321に嵌挿し、耐力構造体4の表面に沿うように当接させる。そして、垂直部32が耐力構造体4表面をスライド可能な遊嵌状態で、フランジ付きナット42を接続ボルト41に締結している。 The vertical portion 32 is fitted with a connecting bolt 41 projecting from the load-bearing structure 4 in the outdoor direction into the elongated hole 321 and brought into contact with the vertical portion 32 along the surface of the load-bearing structure 4. Then, the flanged nut 42 is fastened to the connecting bolt 41 in a loosely fitted state in which the vertical portion 32 can slide on the surface of the load-bearing structure 4.
 壁面構造体2は、接続体3の他の態様である補助接続体3aが設けられている。補助接続体3aもL字型であり、水平部と垂直部(ともに符号省略)を有する。補助接続体3aは、区画壁部24の屋内側となる部分に設けられ、水平部先部が区画壁部24の背面(に位置する背板部25)に、垂直部が耐力構造体4に、それぞれ取り付けられている。なお、補助接続体3aの配置は、ログ材の収縮現象で移動する箇所でないため、垂直部が耐力構造体4表面をスライド可能な構造ではない点で、接続体3と相違する。 The wall surface structure 2 is provided with an auxiliary connecting body 3a, which is another aspect of the connecting body 3. The auxiliary connecting body 3a is also L-shaped and has a horizontal portion and a vertical portion (both are omitted in reference numerals). The auxiliary connecting body 3a is provided on the indoor side portion of the partition wall portion 24, the horizontal portion tip portion is on the back surface (positioned back plate portion 25) of the partition wall portion 24, and the vertical portion is on the load-bearing structure 4. , Each is attached. The arrangement of the auxiliary connecting body 3a is different from that of the connecting body 3 in that the vertical portion is not a structure that can slide on the surface of the load-bearing structure 4 because it is not a place where the auxiliary connecting body 3a moves due to the shrinkage phenomenon of the log material.

For example, the upper surface is formed to a predetermined thickness and the side surface is thinner than the upper surface. It may be an embodiment formed to a thickness. In this case, for example, when the intermediate member moves in the vertical direction, it can be made difficult or less likely to interfere with the side surface of the back plate portion.
 本実施の形態において、垂下部分は、背板部の板面の鉛直線上から、屋内方向に僅かにずらして設けられているが、これに限定するものではなく、例えば、中間部材の側面が薄く形成され、上下方向に移動する際にその側面と干渉しないのであれば、垂下部分は背板部の板面が鉛直線上で面一に一致する態様であってもよい。また、垂下部分を、背板部の板面が鉛直線上で面一に一致する態様に設け、中間部材の側面と相対する部分を切り欠き、中間部材の側面と干渉しない構造にしてもよい。 In the present embodiment, the hanging portion is provided so as to be slightly displaced in the indoor direction from the vertical line of the plate surface of the back plate portion, but the present invention is not limited to this, and for example, the side surface of the intermediate member is thin. As long as it is formed and does not interfere with its side surface when moving in the vertical direction, the hanging portion may have a form in which the plate surface of the back plate portion is flush with each other on a vertical line. Further, the hanging portion may be provided so that the plate surface of the back plate portion is flush with each other on the vertical line, and the portion facing the side surface of the intermediate member is cut out so as not to interfere with the side surface of the intermediate member.
 本実施の形態において、接続体は、ログ壁部の屋内側において、ログ壁部の横幅方向に複数設置しているが、例えば、壁面の広さ等の事情に応じた単数設置を除外するものではない。 In the present embodiment, a plurality of connecting bodies are installed on the indoor side of the log wall portion in the width direction of the log wall portion, but for example, a single installation depending on the circumstances such as the width of the wall surface is excluded. is not it.

 (作 用)
 建物1の作用効果について説明する。建物1は、建物基礎20により、壁面構造体2を含む建物を支持することができる。また、建物基礎20は、地上部202により、外壁21下部を支持し、外壁21下部と地面Gとの間に所定の距離を確保することができる。また、地上部202は、第1貫通孔204により、連通する第2貫通孔223と共に、緊結ボルト271を通すことができる。
(For use)
The action and effect of the building 1 will be described. The building 1 can support the building including the wall surface structure 2 by the building foundation 20. Further, the building foundation 20 supports the lower part of the outer wall 21 by the above-ground portion 202, and can secure a predetermined distance between the lower part of the outer wall 21 and the ground G. Further, the above-ground portion 202 can pass the fastening bolt 271 together with the second through hole 223 that communicates with the first through hole 204.
 建物基礎20は、張出部203上面で外壁21(直接的にはログ壁部22)を支持し、地上部202上面で耐力構造体4を支持している。つまり、建物基礎20は、耐荷重性の高い地上部202の鉛直方向に耐力構造体4を配置し、外壁21を近接配置しており、耐力構造体4が屋内側に配置された纏まりが良い構造となっている。また、外壁21と耐力構造体4が近接配置されることで、接続体3(の水平部31)の長さを短くでき、横揺れ時に接続体3(の水平部31)に加わる応力が低減される。 The building foundation 20 supports the outer wall 21 (directly the log wall portion 22) on the upper surface of the overhanging portion 203, and supports the load-bearing structure 4 on the upper surface of the above-ground portion 202. That is, in the building foundation 20, the load-bearing structure 4 is arranged in the vertical direction of the above-ground portion 202 having a high load-bearing capacity, and the outer wall 21 is arranged close to each other. It has a structure. Further, by arranging the outer wall 21 and the load-bearing structure 4 in close proximity to each other, the length of the connecting body 3 (horizontal portion 31) can be shortened, and the stress applied to the connecting body 3 (horizontal portion 31) during rolling is reduced. Will be done.
 更にまた、建物基礎20は、地上部202が前述の構造であることで、第1貫通孔204の開口部206から露出した雄ネジ部に対してナット272を締結する作業を容易に行うことができる。そして、開口部206は、その配置が建物1外に向けて開放された構造であるため、建築して所定期間経過後にログ壁調整作業を行う際に、建物1内に立ち入ることなく作業を行うことができるので、建物1の使用者のプライバシーを保つことができる。 Furthermore, since the above-ground portion 202 of the building foundation 20 has the above-mentioned structure, the work of fastening the nut 272 to the male screw portion exposed from the opening 206 of the first through hole 204 can be easily performed. can. Since the opening 206 has a structure in which the arrangement is open toward the outside of the building 1, when the log wall adjustment work is performed after the lapse of a predetermined period of time after construction, the work is performed without entering the building 1. Therefore, the privacy of the user of the building 1 can be maintained.
 外壁21は、建物1における建物基礎20から屋根10までの領域の外装を構成する。外壁21は、ログ壁部22を有することで、建物外観あるいは内観の審美性が向上している。加えて、ログ壁部22は、木材に係る炭素貯蔵効果及び省エネルギー効果を以て、地球温暖化防止、温室効果ガス排出削減に寄与する。 The outer wall 21 constitutes the exterior of the area from the building foundation 20 to the roof 10 in the building 1. Since the outer wall 21 has the log wall portion 22, the aesthetic appearance of the exterior or interior of the building is improved. In addition, the log wall portion 22 contributes to the prevention of global warming and the reduction of greenhouse gas emissions by the carbon storage effect and the energy saving effect of wood.
 外壁21は、区画壁部24を有することで、ログ壁部22上方の領域を建物内外に区画している。また、外壁21は、板状の区画壁部24の存在により、外壁が全面ログ壁である場合と比較して、外壁21の構造重量が軽減されている。ひいては、建物1は、上部の構造重量が軽減され、耐震性が向上した構造となっている。そして、区画壁部24は、ログ壁部22よりも加工や改変が容易である。このため、建物1のように、屋根10を勾配の付いた平屋根にすることも容易で、屋根を含む建物上部のデザインについて自由度が高い。 The outer wall 21 has a partition wall portion 24, so that the area above the log wall portion 22 is partitioned inside and outside the building. Further, due to the presence of the plate-shaped partition wall portion 24 of the outer wall 21, the structural weight of the outer wall 21 is reduced as compared with the case where the outer wall is a full log wall. As a result, the building 1 has a structure in which the structural weight of the upper part is reduced and the earthquake resistance is improved. The partition wall portion 24 is easier to process and modify than the log wall portion 22. Therefore, it is easy to make the roof 10 a flat roof with a slope like the building 1, and there is a high degree of freedom in designing the upper part of the building including the roof.
 外壁21は、中間部材23を有することで、ログ壁部22と区画壁部24の隙間が閉じられ、建物1内への外気の流入が抑制される。また、中間部材23は、工場等で製造されたされたものを建築現場に持ち込むのみである。そして、中間部材23は、最上段に位置するログ材221の上部に被せるだけで設置が済む。つまり中間部材23を使用すれば、非熟練作業者であっても、施工を簡易且つ更に速やかで正確に行うことができる。 Since the outer wall 21 has the intermediate member 23, the gap between the log wall portion 22 and the partition wall portion 24 is closed, and the inflow of outside air into the building 1 is suppressed. Further, the intermediate member 23 only brings a product manufactured in a factory or the like to a construction site. Then, the intermediate member 23 can be installed simply by covering the upper part of the log material 221 located at the uppermost stage. That is, if the intermediate member 23 is used, even an unskilled worker can perform the construction easily, more quickly and accurately.
 外壁21は、背板部25を有することで、ログ材の収縮現象が生じてログ材の隙間を調整した際に、垂下部分251によりログ壁部22上端と区画壁部24(すなわち、その上部にある構造材)下端の間に新たな生じる隙間を塞ぐことができる。また、外壁21は、幕板部26を設けたことで、中間部材23近傍の領域を風雨雪から遮断することができる。そして、外壁21は、背板部25と幕板部26が中間部材23近傍の領域を表裏で挟むように配置されていることで、外気や風雨雪から遮断し、虫等の侵入も抑制される。 Since the outer wall 21 has the back plate portion 25, when the shrinkage phenomenon of the log material occurs and the gap of the log material is adjusted, the upper end of the log wall portion 22 and the partition wall portion 24 (that is, the upper portion thereof) are provided by the hanging portion 251. (Structural material in) It is possible to close the newly created gap between the lower ends. Further, the outer wall 21 is provided with the curtain plate portion 26 so that the region near the intermediate member 23 can be shielded from wind, rain and snow. The outer wall 21 is arranged so that the back plate portion 25 and the curtain plate portion 26 sandwich the region near the intermediate member 23 on the front and back sides, thereby blocking from the outside air and wind, rain and snow, and suppressing the invasion of insects and the like. Will be done.
 壁面構造体2は、連通する第1貫通孔204及び第2貫通孔223に緊結ボルト271を通したログ壁調整部27によって、各ログ材の結合状態を保持する。詳しくは、ログ壁調整部27を構成する緊結ボルト271は、第1貫通孔204及び第2貫通孔22に挿通し、第1貫通孔204の開口部206から雄ネジ部が露出しており、この雄ネジ部にナット27を締結している。これにより、ログ壁調整部27として、建物基礎20と外壁21とが緊結している。 The wall surface structure 2 maintains the bonded state of each log material by the log wall adjusting portion 27 in which the binding bolt 271 is passed through the first through hole 204 and the second through hole 223 that communicate with each other. Specifically, the tightening bolt 271 constituting the log wall adjusting portion 27 is inserted into the first through hole 204 and the second through hole 22, and the male screw portion is exposed from the opening 206 of the first through hole 204. A nut 27 is fastened to this male screw portion. As a result, the building foundation 20 and the outer wall 21 are tightly connected as the log wall adjusting unit 27.
 そして、ログ壁調整部27は、ログ材の収縮現象が生じた際に、ナット27を増し締めすることで建物基礎20と外壁21とが再緊結され、ログ材の間が詰まって隙間が閉じる(換言すると、ログ材の隙間を調整する)構造になっている(図5参照)。 Then, when the log material shrinks, the log wall adjusting unit 27 re-tightens the nut 27 to re-tighten the building foundation 20 and the outer wall 21, and the space between the log materials is clogged to close the gap. It has a structure (in other words, adjusts the gap of the log material) (see FIG. 5).
 主に図5を参照して、ログ材の収縮現象と壁面構造体2各部の作用について詳述する。
 図5(a)は建築直後の壁面構造体2各部を示している。このとき、ログ材の間は詰まり、区画壁部24下端と中間部材23上面の間にも隙間は生じていない。
Mainly referring to FIG. 5, the shrinkage phenomenon of the log material and the action of each part of the wall surface structure 2 will be described in detail.
FIG. 5A shows each part of the wall surface structure 2 immediately after construction. At this time, the space between the log materials is clogged, and no gap is formed between the lower end of the partition wall portion 24 and the upper surface of the intermediate member 23.
 図5(b)は、建築から所定期間経過後で、ログ材の収縮現象が生じた状態の壁面構造体2各部を示している。ログ材は、黒矢印の示す方向(軸中心に向かう方向)に収縮し、この結果、ログ材の間には白矢印の示す方向へ隙間が生じる。 FIG. 5B shows each part of the wall surface structure 2 in a state where the shrinkage phenomenon of the log material occurs after a lapse of a predetermined period from the construction. The log material contracts in the direction indicated by the black arrow (direction toward the center of the axis), and as a result, a gap is formed between the log materials in the direction indicated by the white arrow.
 図5(c)は、図5(b)の状況を受けて、ログ壁調整作業を行った後の壁面構造体2各部を示している。詳しくは、ログ壁調整部27のナット272を増し締めすることで、建物基礎20と外壁21とが再緊結され、黒矢印の示す方向にログ材の間が詰まって隙間が埋まっている。 FIG. 5 (c) shows each part of the wall surface structure 2 after performing the log wall adjustment work in response to the situation of FIG. 5 (b). Specifically, by tightening the nut 272 of the log wall adjusting portion 27, the building foundation 20 and the outer wall 21 are re-tightened, and the space between the log materials is clogged in the direction indicated by the black arrow to fill the gap.
 しかし、ログ材の隙間を調整する(ログ材の間を詰める)と、ログ壁部22全体の高さが低くなる。この結果、ログ壁部22上端(より詳しくは、中間部材23上面)と区画壁部24下端の間において、白矢印の示す方向へ新たな隙間が生じることになる。このとき、背板部25を有することで、垂下部分251が、新たに生じた隙間を覆う。これにより、中間部材23の交換やシーリング材の充填の作業を要することなく、建物1の屋内側からこの新たな隙間を塞ぐことができる。 However, if the gap between the log materials is adjusted (the space between the log materials is closed), the height of the entire log wall 22 becomes lower. As a result, a new gap is generated in the direction indicated by the white arrow between the upper end of the log wall portion 22 (more specifically, the upper surface of the intermediate member 23) and the lower end of the partition wall portion 24. At this time, by having the back plate portion 25, the hanging portion 251 covers the newly generated gap. As a result, this new gap can be closed from the indoor side of the building 1 without requiring replacement of the intermediate member 23 and filling of the sealing material.
 そして、ログ壁調整部27のナット272を増し締めにより、ログ壁部22全体の高さが低くなったとしても、接続体3は、垂直部32が耐力構造体4表面をスライド可能な遊嵌状態で取り付けられているので(図4参照)、耐力構造体4の接続ボルト41は、ログ壁部22全体の下方移動に追従して接続体3の長孔321を移動する。これにより、ログ壁調整作業に起因して、接続体3が破断するか、又は、接続体3の取付箇所に係るログ壁部22あるいは耐力構造体4の破損を招くことなく、ログ壁部22と耐力構造体4の接続が維持される。 Then, even if the height of the entire log wall portion 22 is lowered by tightening the nut 272 of the log wall adjusting portion 27, the vertical portion 32 of the connecting body 3 is loosely fitted so that the vertical portion 32 can slide on the surface of the load-bearing structure 4. Since it is attached in a state (see FIG. 4), the connection bolt 41 of the load-bearing structure 4 moves the elongated hole 321 of the connection body 3 following the downward movement of the entire log wall portion 22. As a result, the log wall portion 22 is not broken due to the log wall adjusting work, or the log wall portion 22 or the load-bearing structure 4 related to the attachment location of the connection body 3 is not damaged. And the connection of the load bearing structure 4 is maintained.
 耐力構造体4は、建物1に耐力を付加している。そして、接続体3は、建物1の屋内側において、ログ壁部22と耐力構造体4とを接続し、外壁21に耐震性を付加した構造にしている。接続体3の水平部31は、ログ壁部22と耐力構造体4のスペーサーであると共に、外壁21に加わる水平荷重等の応力を耐力構造体4に負担させている。接続体3の垂直部32は、耐力構造体4に当接して支えている。また、補助接続体3aは、建物1の屋内側において、区画壁部24と耐力構造体4とを接続し、外壁21に耐震性を付加した構造にしている。 The proof stress structure 4 adds proof stress to the building 1. Then, the connecting body 3 connects the log wall portion 22 and the load-bearing structure 4 on the indoor side of the building 1 to have a structure in which earthquake resistance is added to the outer wall 21. The horizontal portion 31 of the connecting body 3 is a spacer between the log wall portion 22 and the load-bearing structure 4, and also causes the load-bearing structure 4 to bear stress such as a horizontal load applied to the outer wall 21. The vertical portion 32 of the connecting body 3 abuts and supports the load-bearing structure 4. Further, the auxiliary connecting body 3a has a structure in which the partition wall portion 24 and the load-bearing structure 4 are connected on the indoor side of the building 1 to add earthquake resistance to the outer wall 21.
 このように、建物1(壁面構造体2)によれば、ログ壁を使用した良好な美観の外壁であると共に、施工及びログ材の収縮現象が生じた際の隙間調整を容易に行うことができる。 As described above, according to the building 1 (wall structure 2), the outer wall has a good appearance using the log wall, and the gap can be easily adjusted during construction and when the log material shrinks. can.

[Modification 3]
FIG. 7A is another aspect (modification example) of the outer wall 21 shown in FIG. 2, and the modification 3 will be described with reference to the same figure. Since the log wall portion 22 and the partition wall portion 24 are the same as those in the first embodiment, the description of their structures and actions and effects will be omitted.
 変形例3において、中間部材23cは、断熱性及び弾性を有する合成樹脂製で、上面部分よりも下方が開口した逆溝形であり、溝内が最上段に位置するログ材221の上面及び側部に沿う形状に設けられている。そして、中間部材23cは、その上面部分に、区画壁部24の下部を受ける区画壁受け部231aが立設されている。中間部材23cは、最上段に配置されたログ材211の上部に取り付けられる。 In the third modification, the intermediate member 23c is made of a synthetic resin having heat insulating properties and elasticity, has an inverted groove shape with an opening below the upper surface portion, and has an upper surface and a side surface of the log material 221 in which the inside of the groove is located at the uppermost stage. It is provided in a shape along the portion. The intermediate member 23c has a partition wall receiving portion 231a that receives the lower portion of the partition wall portion 24 erected on the upper surface portion thereof. The intermediate member 23c is attached to the upper part of the log material 211 arranged at the uppermost stage.
 区画壁受け部231aは、中間部材23cの上面部分の長手方向に亘って平行配置され、基端が上面部分に固着された2枚の板体で構成されている。区画壁受け部231aを構成する板体は、その間隔が、区画壁部24の厚みと略同じか、同厚みよりも僅かに幅広となっており、同間隔部分が溝部232aを構成している。区画壁受け部231aを構成する板体は、その一方が、中間部材23cの下垂部分の室内側となる側面部分と面一になっている。 The partition wall receiving portion 231a is composed of two plates that are arranged in parallel in the longitudinal direction of the upper surface portion of the intermediate member 23c and whose base end is fixed to the upper surface portion. The space between the plates constituting the partition wall receiving portion 231a is substantially the same as or slightly wider than the thickness of the partition wall portion 24, and the same spacing portion constitutes the groove portion 232a. .. One of the plates constituting the partition wall receiving portion 231a is flush with the side surface portion on the indoor side of the hanging portion of the intermediate member 23c.
 区画壁受け部231aは、その高さが、ログ壁部22の段数と経年によるログ材の収縮現象が生じた際の収縮率を計算し、収縮現象が生じたログ壁部22の隙間をログ壁調整部27で詰めることで生じる沈下状態で、区画壁受け部231aの内部から区画壁部24下縁が出ないか、あるいは、区画壁受け部231a上縁と区画壁部24下縁が略同一の高さ(0.01cm以上3cm未満)になるように設定されたものであることが好ましい。 The height of the partition wall receiving portion 231a calculates the shrinkage rate when the shrinkage phenomenon of the log material occurs due to the number of stages of the log wall portion 22 and the aging, and logs the gap of the log wall portion 22 where the shrinkage phenomenon occurs. In the subsidence state caused by packing with the wall adjusting portion 27, the lower edge of the partition wall portion 24 does not come out from the inside of the partition wall receiving portion 231a, or the upper edge of the partition wall receiving portion 231a and the lower edge of the partition wall portion 24 are omitted. It is preferable that the heights are set to be the same (0.01 cm or more and less than 3 cm).
 中間部材23cは、前述の構造であることにより、無加工又は最小限の加工で最上段に配置されたログ材221の上部に容易に取り付けることができ、作業効率が良い。そして、中間部材23cは、区画壁受け部231aの溝部232aに区画壁部24を嵌入させるだけの容易な作業で施工が完了するため、作業効率が良い。 Since the intermediate member 23c has the above-mentioned structure, it can be easily attached to the upper part of the log material 221 arranged at the uppermost stage with no processing or minimal processing, and the work efficiency is good. Since the construction of the intermediate member 23c is completed by simply fitting the partition wall portion 24 into the groove portion 232a of the partition wall receiving portion 231a, the work efficiency is good.
 中間部材23cは、区画壁受け部231aの高さが、ログ壁部22の沈下状態で、区画壁受け部231aの内部から区画壁部24下縁が出ないか、あるいは、区画壁受け部231a上縁と区画壁部24下縁が略同一の高さになるように設定されたものであることにより、経年収縮によるログ材間の隙間をログ壁調整部27により詰めた後に、ログ壁部22上端と区画壁部24下端の間に隙間が生じないように塞ぐことができる。 In the intermediate member 23c, when the height of the partition wall receiving portion 231a is in the submerged state of the log wall portion 22, the lower edge of the partition wall portion 24 does not come out from the inside of the partition wall receiving portion 231a, or the partition wall receiving portion 231a Since the upper edge and the lower edge of the partition wall portion 24 are set to have substantially the same height, the log wall portion is formed after the gap between the log materials due to aged shrinkage is closed by the log wall adjusting portion 27. It can be closed so that no gap is formed between the upper end of the 22 and the lower end of the partition wall portion 24.
 なお、本変形例において、区画壁受け部231aは、その高さが前述の態様であることが好ましいが、例えば、経年によるログ材の収縮現象が生じた際のログ材間の隙間をログ壁調整部27により詰めた後に、区画壁受け部231a上縁と区画壁部24下縁の間に多少の隙間(背板部25の垂下部分251でカバーできる程度。第1実施形態の例であれば、3cm以上10cm未満)が形成される態様であってもよい。この態様であっても、容易な作業で施工が完了するため作業効率が良く、前述した垂下部分251を以て、ログ壁部22上端と区画壁部24下端の間に新たな生じる隙間を塞ぐことができる。 In this modified example, the height of the partition wall receiving portion 231a is preferably in the above-described embodiment. After packing by the adjusting portion 27, there is a slight gap between the upper edge of the partition wall receiving portion 231a and the lower edge of the partition wall portion 24 (to the extent that it can be covered by the hanging portion 251 of the back plate portion 25. For example, 3 cm or more and less than 10 cm) may be formed. Even in this embodiment, the work efficiency is good because the construction is completed by a simple work, and the above-mentioned hanging portion 251 can be used to close the newly generated gap between the upper end of the log wall portion 22 and the lower end of the partition wall portion 24. can.
 〔変形例4〕
 図7(b)は、図2に示した外壁21の他の態様(変形例)であり、同図を参照して変形例4について説明する。なお、ログ壁部22と区画壁部24は、第1実施形態と同様であるため、その構造および作用効果の説明は省略する。
[Modification example 4]
FIG. 7B is another aspect (modification example) of the outer wall 21 shown in FIG. 2, and the modification 4 will be described with reference to the same figure. Since the log wall portion 22 and the partition wall portion 24 are the same as those in the first embodiment, the description of their structures and actions and effects will be omitted.
 変形例4において、中間部材23dは、断熱性及び弾性を有する合成樹脂製で、所定の高さを有し、上面部分及び下面部分が開口している。中間部材23dは、下面部分が下方向に開口した逆溝形であり、溝内が最上段に位置するログ材221の上面及び側部に沿う形状に設けられている。中間部材23dは、最上段に配置されたログ材211の上部に取り付けられる。 In the modified example 4, the intermediate member 23d is made of a synthetic resin having heat insulating properties and elasticity, has a predetermined height, and the upper surface portion and the lower surface portion are open. The intermediate member 23d has a reverse groove shape in which the lower surface portion opens downward, and is provided in a shape along the upper surface and side portions of the log material 221 whose inside of the groove is located at the uppermost stage. The intermediate member 23d is attached to the upper part of the log material 211 arranged at the uppermost stage.
 そして、中間部材23dは、その上面部分の幅方向中央且つ上面部分の長手方向に亘って形成された所定深さの凹溝(溝部232b)である区画壁受け部231bが形成されている。区画壁受け部231bは、その溝部232bの間隔が、区画壁部24の厚みと略同じか、同厚みよりも僅かに幅広となっている。 The intermediate member 23d is formed with a partition wall receiving portion 231b which is a concave groove (groove portion 232b) having a predetermined depth formed in the center of the upper surface portion in the width direction and in the longitudinal direction of the upper surface portion. The space between the groove portions 232b of the partition wall receiving portion 231b is substantially the same as or slightly wider than the thickness of the partition wall portion 24.
 区画壁受け部231bは、溝部232bの深さが、ログ壁部22の段数と経年によるログ材の収縮現象が生じた際の収縮率を計算し、収縮現象が生じたログ壁部22の隙間をログ壁調整部27で詰めることで生じる沈下状態で、区画壁受け部231bの内部から区画壁部24下縁が出ないか、あるいは、区画壁受け部231b上縁と区画壁部24下縁が略同一の高さ(0.01cm以上3cm未満)になるように設定されたものであることが好ましい。 In the partition wall receiving portion 231b, the depth of the groove portion 232b calculates the shrinkage rate when the shrinkage phenomenon of the log material occurs due to the number of stages of the log wall portion 22 and the aging, and the gap of the log wall portion 22 where the shrinkage phenomenon occurs. In the subsidence state caused by packing the log wall adjusting portion 27, the lower edge of the partition wall portion 24 does not come out from the inside of the partition wall receiving portion 231b, or the upper edge of the partition wall receiving portion 231b and the lower edge of the partition wall portion 24 Is preferably set so as to have substantially the same height (0.01 cm or more and less than 3 cm).
 中間部材23dは、前述の構造であることにより、無加工又は最小限の加工で最上段に配置されたログ材221の上部に容易に取り付けることができ、作業効率が良い。そして、中間部材23dは、区画壁受け部231bの溝部232bに区画壁部24を嵌入させるだけの容易な作業で施工が完了するため、作業効率が良い。加えて、中間部材23dは、区画壁受け部231bの側板となる部分(溝部232bの幅方向両側となる部分)が肉厚であるため、水平荷重が生じた際に区画壁部24の動きによって側板となる部分が破損することを抑制することができる。 Since the intermediate member 23d has the above-mentioned structure, it can be easily attached to the upper part of the log material 221 arranged at the uppermost stage with no processing or minimal processing, and the work efficiency is good. Since the construction of the intermediate member 23d is completed by simply fitting the partition wall portion 24 into the groove portion 232b of the partition wall receiving portion 231b, the work efficiency is good. In addition, since the portion of the intermediate member 23d that becomes the side plate of the partition wall receiving portion 231b (the portion that becomes both sides in the width direction of the groove portion 232b) is thick, the movement of the partition wall portion 24 when a horizontal load is generated causes the intermediate member 23d to move. It is possible to prevent the portion that becomes the side plate from being damaged.
 なお、本変形例において、区画壁受け部231bは、溝部232bの深さが前述の態様であることが好ましいが、例えば、経年収縮によるログ材間の隙間をログ壁調整部27により詰めた後に、区画壁受け部231b上縁と区画壁部24下縁の間に多少の隙間(背板部25の垂下部分251でカバーできる程度。第1実施形態の例であれば、3cm以上10cm未満)が形成される態様であってもよい。この態様であっても、容易な作業で施工が完了するため作業効率が良く、前述した垂下部分251を以て、ログ壁部22上端と区画壁部24下端の間に新たな生じる隙間を塞ぐことができる。 In this modification, the partition wall receiving portion 231b preferably has a groove portion 232b having a depth of the above-described embodiment. , Some gap between the upper edge of the partition wall receiving portion 231b and the lower edge of the partition wall portion 24 (to the extent that it can be covered by the hanging portion 251 of the back plate portion 25. In the example of the first embodiment, 3 cm or more and less than 10 cm) May be formed. Even in this embodiment, the work efficiency is good because the construction is completed by a simple work, and the above-mentioned hanging portion 251 can be used to close the newly generated gap between the upper end of the log wall portion 22 and the lower end of the partition wall portion 24. can.

 図8は、図2に示した建物基礎20の他の態様(変形例)であり、同図を参照して変形例5について説明する。なお、建物基礎20aは、後述する相違点を除き、第1実施形態と同様であるため、その構造および作用効果の説明は省略する。
[Modification 5]
FIG. 8 is another aspect (modification example) of the building foundation 20 shown in FIG. 2, and the modification 5 will be described with reference to the same figure. Since the building foundation 20a is the same as that of the first embodiment except for the differences described later, the description of its structure and its action and effect will be omitted.
 変形例5において、建物基礎20aは、地下基礎部(図示省略)と地上部202aを含み、地上部202aは地上部202よりも幅方向が厚く形成されている。地上部202aは、高さ方向の中間位置に、屋外側に開口した方形の切欠部207が形成されている。地上部202aは、その上面に開口部205aが形成され、切欠部207の天部に形成された開口部206aに至る、緊結ボルト271が挿通可能な第1貫通孔204aが形成されている。 In the modified example 5, the building foundation 20a includes an underground foundation portion (not shown) and an above-ground portion 202a, and the above-ground portion 202a is formed thicker in the width direction than the above-ground portion 202. The above-ground portion 202a has a square notch 207 opened to the outside at an intermediate position in the height direction. An opening 205a is formed on the upper surface of the above-ground portion 202a, and a first through hole 204a through which the binding bolt 271 can be inserted is formed up to the opening 206a formed at the top of the notch 207.
 建物基礎20aは、地上部202aが前述した構成であるため、その上面に、壁面構造体2と耐力構造体4を近接配置することができる。また、建物基礎20aは、幅方向に厚い構造であるため、切欠部207を有しながらも、地上部202よりも堅牢な構造となっている。 Since the above-ground portion 202a of the building foundation 20a has the above-mentioned configuration, the wall surface structure 2 and the load-bearing structure 4 can be arranged close to each other on the upper surface thereof. Further, since the building foundation 20a has a structure thick in the width direction, it has a structure that is more robust than the above-ground portion 202 even though it has a notch portion 207.

 図9は、図2に示した壁面構造体2の他の態様(変形例)であり、同図を参照して変形例6について説明する。なお、壁面構造体2aは、後述する相違点を除き、第1実施形態と同様であるため、その構造および作用効果の説明は省略する。
[Modification 6]
FIG. 9 is another aspect (modification example) of the wall surface structure 2 shown in FIG. 2, and the modification 6 will be described with reference to the same figure. Since the wall surface structure 2a is the same as that of the first embodiment except for the differences described later, the description of its structure and its action and effect will be omitted.
 壁面構造体2aを構成する外壁21aは、屋外側に耐火壁部5を有している。耐火壁部5は、屋根10の軒下面から、区画壁部24の全部及びログ壁部22の下端に至る領域を覆うように配設されている。 The outer wall 21a constituting the wall surface structure 2a has a fireproof wall portion 5 on the outdoor side. The fireproof wall portion 5 is arranged so as to cover an area from the lower surface of the eaves of the roof 10 to the entire partition wall portion 24 and the lower end of the log wall portion 22.
 なお、図8において、壁面構造体2aは、耐火壁部5が外壁21aの全面を覆う態様であるが、これに限定するものではなく、例えば、耐火壁部5が区画壁部24は覆わずにログ壁部22を覆う態様(つまり、「少なくともログ壁を覆う」態様)であってもよい。また、「耐火」壁部のみならず、「準耐火」あるいは「防火」壁部で代替することもできる。 In FIG. 8, the wall surface structure 2a has a mode in which the refractory wall portion 5 covers the entire surface of the outer wall 21a, but the present invention is not limited to this. For example, the refractory wall portion 5 does not cover the partition wall portion 24. It may be a mode of covering the log wall portion 22 (that is, a mode of "at least covering the log wall"). Moreover, not only the "fireproof" wall part but also the "quasi-fireproof" or "fireproof" wall part can be substituted.
 壁面構造体2aは、前述した耐火壁部5を有する構造であるため、ログ壁部22を含む外壁21に耐火性を付与している。これにより、壁面構造体2aは、これを適用する建物1を都市部等に建築した場合において、隣接して距離が近い建物が火災に遭ったとしても、木材であるログ壁22が延焼しにくい構造となる。 Since the wall surface structure 2a has the above-mentioned fireproof wall portion 5, the outer wall 21 including the log wall portion 22 is provided with fire resistance. As a result, when the building 1 to which the wall structure 2a is applied is constructed in an urban area or the like, the log wall 22 made of wood is unlikely to spread even if a building adjacent to the wall structure 2a is close to the fire. It becomes a structure.

 (作 用)
 建物1bの作用効果について説明する。
(For use)
The action and effect of the building 1b will be described.
 (建物1bの1階部分)
 建物1bは、建物基礎20により、建物躯体、壁面構造体2b、2cを含む建物を支持することができる。建物基礎20は、外壁21c下部と地面との間に所定の距離を確保することができる。また、建物基礎20は、張出部203上面で外壁21cを支持し、地上部202上面で耐力構造体4bを支持している。
(1st floor of building 1b)
The building 1b can support the building including the building frame and the wall surface structures 2b and 2c by the building foundation 20. The building foundation 20 can secure a predetermined distance between the lower part of the outer wall 21c and the ground. Further, the building foundation 20 supports the outer wall 21c on the upper surface of the overhanging portion 203 and the load-bearing structure 4b on the upper surface of the above-ground portion 202.
 つまり、建物基礎20は、耐荷重性の高い地上部202の鉛直方向に耐力構造体4bを配置し、外壁21cを近接配置しており、耐力構造体4bが屋内側に配置された纏まりが良い構造となっている。また、外壁21cと耐力構造体4bが近接配置されることで、接続体3(の水平部)の長さを短くでき、横揺れ時に接続体3(の水平部)に加わる応力が低減される。 That is, in the building foundation 20, the load-bearing structure 4b is arranged in the vertical direction of the above-ground portion 202 having a high load-bearing capacity, and the outer wall 21c is arranged close to each other. It has a structure. Further, by arranging the outer wall 21c and the load-bearing structure 4b close to each other, the length of the connecting body 3 (horizontal portion) can be shortened, and the stress applied to the connecting body 3 (horizontal portion) during rolling is reduced. ..
 また、建物基礎20に設けた第1貫通孔204は、連通する第2貫通孔223と共に、緊結ボルト271を通すことができ、第1貫通孔204の下方の開口部から露出した雄ネジ部に対してナット272を締結する作業を容易に行うことができる。そして、ナット272は、その配置が建物1b外に向けて開放された構造であるため、建築して所定期間経過後にログ壁調整作業を行う際に、建物1b内に立ち入ることなく作業を行うことができるので、建物1の使用者のプライバシーを保つことができる。 Further, the first through hole 204 provided in the building foundation 20 can pass the tightening bolt 271 together with the second through hole 223 that communicates with the male screw portion exposed from the opening below the first through hole 204. On the other hand, the work of fastening the nut 272 can be easily performed. Since the nut 272 has a structure in which the arrangement is open toward the outside of the building 1b, when the log wall adjustment work is performed after the lapse of a predetermined period of construction, the work is performed without entering the building 1b. Therefore, the privacy of the user of the building 1 can be maintained.
 外壁21cは、建物1bの1階部分の外装を構成する。ログ壁部22cは、木材に係る炭素貯蔵効果及び省エネルギー効果を以て、地球温暖化防止、温室効果ガス排出削減に寄与する。耐火壁部51は、ログ壁部22cを含む外壁21cに耐火性を付与している。これにより、壁面構造体2bは、これを適用する建物1bを都市部等に建築した場合において、隣接して距離が近い建物が火災に遭ったとしても、木材であるログ壁22cが延焼しにくい構造となる。 The outer wall 21c constitutes the exterior of the first floor of the building 1b. The log wall portion 22c contributes to the prevention of global warming and the reduction of greenhouse gas emissions by the carbon storage effect and the energy saving effect of wood. The fireproof wall portion 51 imparts fire resistance to the outer wall 21c including the log wall portion 22c. As a result, when the building 1b to which the wall structure 2b is applied is constructed in an urban area or the like, the log wall 22c, which is made of wood, is unlikely to spread even if a building adjacent to the wall structure 2b is close to the fire. It becomes a structure.
 中間部材23は、ログ壁部22cと天井部の隙間を閉じ、建物1b内への外気の流入を抑制する。中間部材23は、最上段に位置するログ材221cの上部に被せるだけで設置が済み、非熟練作業者であっても、施工を簡易且つ更に速やかで正確に行うことができる。なお、外壁21cは、背板部(図示省略)を有することで、ログ材の収縮現象が生じてログ材の隙間を調整した際に、ログ壁部22c上端と天井部の間に新たな生じる隙間を塞ぐことができる。 The intermediate member 23 closes the gap between the log wall portion 22c and the ceiling portion, and suppresses the inflow of outside air into the building 1b. The intermediate member 23 can be installed simply by covering the upper part of the log material 221c located at the uppermost stage, and even an unskilled worker can perform the construction easily, more quickly and accurately. Since the outer wall 21c has a back plate portion (not shown), when a shrinkage phenomenon of the log material occurs and the gap of the log material is adjusted, a new one is generated between the upper end of the log wall portion 22c and the ceiling portion. You can close the gap.
 壁面構造体2bは、前述した壁面構造体2と同様の作用効果を奏し、ログ壁調整部27によって、各ログ材の結合状態を保持すると共に、ログ材の収縮現象が生じた際に、ナット27の増し締めで再緊結し、ログ材の間が詰まって隙間を閉じる構造になっている。 The wall surface structure 2b has the same function and effect as the wall surface structure 2 described above, and the log wall adjusting unit 27 maintains the bonded state of each log material, and when a shrinkage phenomenon of the log material occurs, a nut It is re-tightened by retightening 27, and the structure is such that the space between the log materials is clogged and the gap is closed.
 耐力構造体4bは、建物1bに耐力を付加している。そして、接続体3は、建物1bの屋内側1階部分において、ログ壁部22cと耐力構造体4bとを接続し、外壁21cに耐震性を付加した構造にしている。接続体3は、その水平部がログ壁部22cと耐力構造体4bのスペーサーであると共に、外壁21cに加わる水平荷重等の応力を耐力構造体4bに負担させている。接続体3はその垂直部が耐力構造体4bに当接して支えている。なお、補助接続体(図示省略)も、建物1bの屋内側の屋内側1階部分において、ログ壁部22cと耐力構造体4bとを接続し、外壁21cに耐震性を付加した構造にしている。 The proof stress structure 4b adds proof stress to the building 1b. The connecting body 3 connects the log wall portion 22c and the load-bearing structure 4b on the first floor on the indoor side of the building 1b, and has a structure in which earthquake resistance is added to the outer wall 21c. The horizontal portion of the connecting body 3 is a spacer between the log wall portion 22c and the load-bearing structure 4b, and the load-bearing structure 4b bears stress such as a horizontal load applied to the outer wall 21c. The vertical portion of the connecting body 3 abuts on and supports the load-bearing structure 4b. The auxiliary connection body (not shown) also has a structure in which the log wall portion 22c and the load-bearing structure 4b are connected to the outer wall 21c to add earthquake resistance to the indoor first floor portion on the indoor side of the building 1b. ..
 (建物1bの2階部分)
 建物1bの2階部分は、上階床部11により、建物躯体の上階部、壁面構造体2cを含む建物を支持することができる。また、上階床部11は、その上面で外壁21dと耐力構造体4cを支持している。
(2nd floor of building 1b)
The second floor portion of the building 1b can support the building including the upper floor portion of the building frame and the wall surface structure 2c by the upper floor portion 11. Further, the upper floor portion 11 supports the outer wall 21d and the load-bearing structure 4c on the upper surface thereof.
 建物1bの2階部分においても、耐力構造体4cと外壁21dが近接配置され、耐力構造体4cが屋内側に配置された纏まりが良く、加えて、接続体3(の水平部)の長さを短くでき、横揺れ時に接続体3(の水平部)に加わる応力が低減される構造となっている。 Also on the second floor of the building 1b, the load-bearing structure 4c and the outer wall 21d are arranged close to each other, and the load-bearing structure 4c is arranged indoors. The structure is such that the stress applied to (the horizontal portion of) the connecting body 3 (horizontal portion) at the time of rolling can be reduced.
 外壁21dは、建物1bの2階部分の外装を構成する。ログ壁部22dは、木材に係る炭素貯蔵効果及び省エネルギー効果を以て、地球温暖化防止、温室効果ガス排出削減に寄与する。耐火壁部52は、ログ壁部22dを含む外壁21に耐火性を付与し、耐火壁部51と同様、近距離で火災が起きたとしても、ログ壁22dが延焼しにくい構造となる。 The outer wall 21d constitutes the exterior of the second floor of the building 1b. The log wall portion 22d contributes to the prevention of global warming and the reduction of greenhouse gas emissions by the carbon storage effect and the energy saving effect of wood. The fireproof wall portion 52 imparts fire resistance to the outer wall 21 including the log wall portion 22d, and like the fireproof wall portion 51, the log wall 22d has a structure that makes it difficult for the log wall 22d to spread even if a fire occurs at a short distance.
 中間部材23は、ログ壁部22dと天井部の隙間を閉じ、建物1b内への外気の流入を抑制する。中間部材23は、最上段に位置するログ材221dの上部に被せるだけで設置が済み、非熟練作業者であっても、施工を簡易且つ更に速やかで正確に行うことができる。なお、外壁21dは、背板部(図示省略)を有することで、ログ材の収縮現象が生じてログ材の隙間を調整した際に、ログ壁部22d上端と天井部の間に新たな生じる隙間を塞ぐことができる。 The intermediate member 23 closes the gap between the log wall portion 22d and the ceiling portion, and suppresses the inflow of outside air into the building 1b. The intermediate member 23 can be installed simply by covering the upper part of the log material 221d located at the uppermost stage, and even an unskilled worker can perform the construction easily, more quickly and accurately. Since the outer wall 21d has a back plate portion (not shown), when a shrinkage phenomenon of the log material occurs and the gap of the log material is adjusted, a new one is generated between the upper end of the log wall portion 22d and the ceiling portion. You can close the gap.
 ログ壁調整部27aは、開口部224からアクセスが容易なターンバックル273の胴を回転させるだけで、両端に取り付けられた2本の緊結ボルト271a、272bが締め込まれ、張力を容易に調節することができる。つまり、壁面構造体2cは、前述した壁面構造体2と近似した作用効果を奏し、ログ壁調整部27aによって、各ログ材の結合状態を保持すると共に、ログ材の収縮現象が生じた際に、ターンバックル273の増し締めで再緊結し、ログ材の間が詰まって隙間を閉じる構造になっている。 The log wall adjusting portion 27a simply rotates the body of the turnbuckle 273, which is easily accessible from the opening 224, and two fastening bolts 271a and 272b attached to both ends are tightened to easily adjust the tension. be able to. That is, the wall surface structure 2c exerts an action effect similar to that of the wall surface structure 2 described above, and when the log wall adjusting unit 27a maintains the bonded state of each log material and the shrinkage phenomenon of the log material occurs. , The turnbuckle 273 is retightened to re-tighten, and the log material is clogged to close the gap.
 耐力構造体4bは、建物1bに耐力を付加している。そして、接続体3は、建物1bの屋内側1階部分において、ログ壁部22cと耐力構造体4bとを接続し、外壁21cに耐震性を付加した構造にしている。接続体3は、その水平部がログ壁部22cと耐力構造体4bのスペーサーであると共に、外壁21cに加わる水平荷重等の応力を耐力構造体4bに負担させている。接続体3はその垂直部が耐力構造体4bに当接して支えている。なお、補助接続体(図示省略)も、建物1bの屋内側の屋内側1階部分において、ログ壁部22cと耐力構造体4bとを接続し、外壁21cに耐震性を付加した構造にしている。 The proof stress structure 4b adds proof stress to the building 1b. The connecting body 3 connects the log wall portion 22c and the load-bearing structure 4b on the first floor on the indoor side of the building 1b, and has a structure in which earthquake resistance is added to the outer wall 21c. The horizontal portion of the connecting body 3 is a spacer between the log wall portion 22c and the load-bearing structure 4b, and the load-bearing structure 4b bears stress such as a horizontal load applied to the outer wall 21c. The vertical portion of the connecting body 3 abuts on and supports the load-bearing structure 4b. The auxiliary connection body (not shown) also has a structure in which the log wall portion 22c and the load-bearing structure 4b are connected to the outer wall 21c to add earthquake resistance to the indoor first floor portion on the indoor side of the building 1b. ..
 〔変形例7〕
 図10(b)は、図10(a)に示した建物1bの他の態様(変形例)であり、同図を参照して変形例7について説明する。なお、建物1cは、後述する相違点を除き、第2実施形態と同様であるため、その構造および作用効果の説明は省略する。
[Modification 7]
FIG. 10B is another aspect (modification example) of the building 1b shown in FIG. 10A, and the modification 7 will be described with reference to the same figure. Since the building 1c is the same as the second embodiment except for the differences described later, the description of its structure and its operation and effect will be omitted.
 建物1cは、RC・SRC造であり、耐力構造体を有していない点、耐力構造体と壁面構造体を接続する接続体を有しない点、において建物1cと相違する。なお、RC造は、鉄筋コンクリート造(Reinforced Concrete Construction)の略で、SRC造は、鉄骨鉄筋コンクリート造(Steel Reinforced Concrete Construction)の略である。建物1cは、建物躯体が十分な強度を有し、壁面構造体に近接する耐力構造体が無く、構造を単純化することができる。 Building 1c is different from building 1c in that it is an RC / SRC structure and does not have a load-bearing structure and does not have a connecting body that connects the load-bearing structure and the wall surface structure. The RC structure is an abbreviation for Reinforced Concrete Construction, and the SRC structure is an abbreviation for Steel Reinforced Concrete Construction. The structure of the building 1c can be simplified because the building frame has sufficient strength and there is no load-bearing structure in the vicinity of the wall surface structure.
