Description
本発明は、高断熱・高気密の木造住宅を造る場合横加材間の耐力壁に対し断熱材を用いないで蒸煮・乾燥処理した無垢の厚板部材に形状加工を施したログ部材を用いて現場で施行する壁構築工法に関するものである。この工法は、非耐力壁の構築工法にも適用できる。 The present invention uses a log member obtained by performing shape processing on a solid plank member that has been steamed and dried without using a heat-insulating material against a load-bearing wall between laterally-added materials when building a highly heat-insulated and air-tight wooden house. It relates to the wall construction method to be implemented on site. This method can also be applied to the construction method of non-bearing walls.
国土交通省の次世代省エネルギー基準に基づき、建材業界においては各種の断熱材・新建材が商品化され、それに対応した各種の高断熱・高気密に対応した建築物工法が実用化され,木造住宅にも適用されている。しかし、これらの新建材を多用する現行の高断熱・高気密の木造建築物はグローバルな地球温暖化防止・地球環境保全・省資源・省エネルギーの見地から課題があり、今後早急に解決すべき必須事項である。 Based on the next-generation energy-saving standards of the Ministry of Land, Infrastructure, Transport and Tourism, various heat insulation materials and new building materials have been commercialized in the building materials industry, and various high heat insulation and high airtight building construction methods have been put into practical use, and wooden houses It has also been applied. However, current high-insulation and air-tight wooden buildings that make heavy use of these new building materials have problems from the viewpoints of global warming prevention, global environmental protection, resource saving, and energy saving. It is a matter.
次に、木材の経年変化に伴う動き(干割れ、曲がりや収縮等)を安定化し,樹脂の成分を除去する蒸煮・乾燥技術、また木材の防火処理技術により木材の短所は解消されてきている。更に、木材は蓄熱・調湿・遮熱・遮音・防臭、そして癒し等の効果を有し,また無垢の木材を建築部材として使用する場合の総エネルギーは新建材に比べ少なく、理想の建材として見直されてきた。 Next, the shortcomings of wood have been eliminated by steaming / drying technology that removes resin components by stabilizing movement (dry cracking, bending, shrinkage, etc.) associated with aging of wood, and fire prevention technology of wood. . Furthermore, wood has effects such as heat storage, humidity control, heat insulation, sound insulation, deodorization, and healing, and the total energy when using solid wood as a building material is less than that of new building materials, making it an ideal building material. It has been reviewed.
これらの木材処理技術の進歩に加え,木材の形状加工技術は加工機の進歩により、複雑な形状加工が精度よく行えるようになった。 In addition to these advances in wood processing technology, the shape processing technology of wood has made it possible to perform complex shape processing with high precision due to advances in processing machines.
在来の軸組木造建築においては、屋根下地部には桁と棟木との間に複数本の垂木を適切な間隔に配置して固定し,垂木の上に木板を敷き詰めクギで打ち付け、その上に屋根材を敷設していた。また床部においても,大引きに複数本の根太を適切な間隔に配置して固定し,根太の上に木板を敷き詰めクギで打ち付け、その上に畳を敷いていた。この工法では垂木と木板との間、根太と木板との間に空隙が生じるが、今まで,これらの空隙に所要の気密をしようという概念はなかった。 In conventional framed wooden construction, a plurality of rafters are arranged at appropriate intervals between the girders and purlins on the roof base, and a wooden board is laid on the rafters and nailed with nails. The roofing material was laid on. Also, on the floor, a large number of joists were fixed and placed at appropriate intervals, and a wooden board was laid on the joists and nailed with nails, and tatami mats were laid on them. In this method, there are gaps between the rafters and the wooden board, and between the joists and the wooden board, but until now there has been no concept of achieving the required airtightness in these gaps.
壁部において、内壁では柱間の空間を木板や新建材のボード等で敷設し,内壁と新建材の外壁との間にグラスウールやウレタン等の断熱材を充填し、断熱材を防湿気密シートで覆っていた。防湿気密シートを繋ぐ場合には、シートの継ぎ目で一部重ね合わせて固定する作業または重ね合わせずに継ぎ目に密着テープを施して固定する作業等があった。更に、グラスウールや防湿気密シートは水分吸収による変形、固定鋲の腐食によって剥離・脱落が起こると、断熱・気密性が確保できなかった。 In the wall, the space between the pillars on the inner wall is laid with a wooden board or a board of new building material, and a heat insulating material such as glass wool or urethane is filled between the inner wall and the outer wall of the new building material, and the heat insulating material is a moisture-proof and airtight sheet. I covered it. When connecting moisture-proof and air-tight sheets, there is an operation of partially overlapping and fixing at the joint of the sheets, an operation of applying an adhesive tape to the seam without overlapping, and the like. Furthermore, if the glass wool or moisture-proof and air-tight sheet is peeled off or dropped due to deformation due to moisture absorption or corrosion of the fixing rod, heat insulation and air tightness cannot be secured.
これらの断熱材は内外壁の間、天井の上、床下に敷設されるが,経年変化・特性劣化の進行状況を外部から監視できない。加えて、それらの修復は容易ではなかった。また、これらの断熱材を用いた壁は構造的に脆弱で耐力壁にはなりえず、安全・蓄熱・調湿等の特性は木材に比べ本質的に劣り、癒し効果もない。 These insulations are laid between the inner and outer walls, above the ceiling and under the floor, but the progress of aging and characteristic deterioration cannot be monitored from the outside. In addition, their repair has not been easy. In addition, the walls using these heat insulating materials are structurally fragile and cannot become load bearing walls, and their safety, heat storage, humidity control, and other characteristics are essentially inferior to wood and have no healing effect.
現在,本発明に直接係る公知例は見当たらない。同じ課題を解決する特許文献としては、例えば、特開20002−167879号公報がある。この公報に在来木造建築物の内外壁、床、屋根下地材を無垢の木材のみで高断熱・高気密用に最小単位の無垢木材の接触面に接着剤を塗布し繋ぎながら所要形状の耐力パネルに成形加工し、それを横加材間に敷設する構築工法が提案されている。しかし、このパネル構築工法には部材として蒸煮・乾燥した木材を用いることや特殊形状加工した部材を用いる等の記載はない。このパネル構築工法では、部材の経年変化・調湿作用により接合面が剥離すると、気密性が損なわれる懸念がある。また、パネルの成形作業、その現場取付け作業に専門技術者が必要である。 At present, there are no known examples directly related to the present invention. As a patent document that solves the same problem, there is, for example, Japanese Unexamined Patent Publication No. 20002-167879. In this gazette, the inner and outer walls, floors, and roof base materials of conventional wooden buildings are made of pure wood only, and the required strength of the required shape while applying adhesive to the contact surfaces of the smallest solid wood for high insulation and high airtightness. A construction method has been proposed in which a panel is molded and then laid between side panels. However, in this panel construction method, there is no description such as using steamed and dried wood as a member, or using a member with a special shape processing. In this panel construction method, there is a concern that the airtightness is impaired when the joint surface peels off due to aging and humidity control of the members. In addition, a specialist engineer is required for the panel forming work and the field mounting work.
木造住宅の面構築において、蒸煮・乾燥処理した無垢の厚板部材に特殊形状加工を施したログ部材を用いて気密性を確保しながら現場で一枚ずつ上下の横加材に剛体定着し、かつ各ログ部材同士を剛体として繋ぎ左右の横加材に剛体定着し耐力面壁として用いるという構築工法の発想は今までなかった。
無垢の部材を用いた在来の軸組木造住宅は断熱性・気密性に劣り、壁面に断熱材を併用する。また、横加材間には筋交いや間柱が必要であり、建築完成までに異なる職種が必要となり、それぞれに工数がかかった。これらの課題を解決する。 Conventional timber framed wooden houses using solid materials are inferior in heat insulation and airtightness, and use heat insulation on the wall. In addition, bracing and studs were required between the side bracings, and different job types were required before the construction was completed, each requiring man-hours. Solve these issues.
本発明の耐力壁の構築工法においては、断熱特性を持たせるのに十分な厚さに製材した無垢の厚板部材を蒸煮・乾燥処理した後、左右両側面に雇いザネや本ザネ等の気密加工を施し、更に上下両木口にスリット加工を施し、この部材を面構成の最小要素として用いる。以下、この最小要素の部材をログ部材、雇いザネの溝に挿入する多面体の芯をライナー、ログ部材上下両木口のスリットと上下横加材内面のスリットとの間に挿入する接続板をプレートと記す。またプレートの内、耐力壁用を耐力プレート、非耐力壁用を非耐力プレートと記す。 In the construction method of the bearing wall according to the present invention, a solid plank member made to a thickness sufficient to give heat insulation properties is steamed and dried, and then airtight on the left and right sides, such as hires and saps. Processing is performed, and slit processing is further performed on the upper and lower ends, and this member is used as the minimum element of the surface configuration. Hereinafter, this minimum element member is referred to as a log member, a polyhedron core inserted into the groove of the hiring rod, a liner, and a connecting plate inserted between the slits of the upper and lower ends of the log member and the slits of the inner surfaces of the upper and lower lateral members are referred to as plates. . Of the plates, the bearing wall is referred to as a bearing plate, and the non-bearing wall is referred to as a non-bearing plate.
壁部に対しては、ログ部材と接する横加材間で、このログ部材を上下の横加材に耐力プレートを介してダボやピンで剛体定着し、また左右の横加材を含めログ部材同士をライナーで気密接続し、更にログ部材をダボやピンで剛体定着してパネル化し、このパネルを左右の横加材のいずれかを可動柱としてピンやダボで左右の横加材に剛体定着して耐力壁とする。なお、このログ部材は一枚あるいは数枚単位で繋ぐこともできる。 For the wall, between the lateral members in contact with the log member, this log member is rigidly fixed to the upper and lower lateral members with a dowel or pin via a load bearing plate, and the log members including the left and right lateral members are lined together. In addition, the log member is rigidly fixed with dowels and pins to form a panel, and this panel is fixed to the left and right lateral members with pins and dowels using either of the left and right lateral members as a movable column. To do. The log members can be connected one by one or several units.
また屋根下地部や床部に対しては、ログ部材を一枚ないし数枚ずつ気密接続して所定のスペースに敷設し、ボルトやビスで土台や桁に固定する。また2階の天井を施工する場合は、ログ部材面を桁上部に床部と同様に気密接続して所定のスペースに敷設し、ボルトやビスで横加材材に固定する。 In addition, one or several log members are hermetically connected to the roof base and floor, and laid in a predetermined space, and fixed to a base or a girder with bolts or screws. When constructing the ceiling of the second floor, the log member surface is hermetically connected to the upper part of the girders in the same manner as the floor part, and is laid in a predetermined space, and is fixed to the transverse material with bolts or screws.
なお、これらのログ部材面と躯体の構造材との接触面の内部にはコーキングを施して回り縁で封じ気密を確保する。また、外部にはコーキングを施して回り縁や水切りで封じ気密・防水を確保する。 In addition, caulking is applied to the inside of the contact surface between the log member surface and the structural member of the casing to ensure sealing and airtightness at the peripheral edge. In addition, caulking is applied to the outside and sealed with a peripheral edge or drainage to ensure airtightness and waterproofness.
なお、防火規制地域にログ部材壁を外壁として共用する場合は、規制地域に応じ防火・表面温度硬化処理を施したログ部材またはこのログ部材壁の外部に耐火新建材やレンガ等の外壁を併設することができる。 In addition, when sharing a log member wall as an outer wall in a fire prevention regulated area, a log member that has been subjected to fire prevention and surface temperature hardening treatment according to the regulated area or an external wall such as a fireproof new building material or brick outside the log member wall can do.
本発明は、蒸煮・乾燥処理を施した厚板部材を用いた面構築工法であるため,次のような効果がある。
○ 本構築工法は引張り応力に対してはプレートによる横加材との剛体定着で、せん断応力に対してはダボによるログ部材間および横加材との剛体定着で対抗できるため、筋交いや間柱なしに現場作業でログ部材を用いて耐力壁の構築ができる。部材点数が少なく、壁の構築工法は簡単で専門技術者でなくてもこの作業に参加でき、建築工数を軽減できる。
○ 木材のみを用いた木造住宅でありながら建築物の大半を占める面構成の部材は安定で断熱性・気密性に優れ、木材の蓄熱効果と相俟って、暖冷房電力費の少ない快適な居住性が確保できる。
○ 面壁に断熱材や新建材を一切用いていないため、部屋に有害物質の放出はなく、安全・健康・調湿・癒し等の面でも良好な居住性が確保できる。
○ 壁面は内外一枚構成のため、壁面の監視は容易であり、リホームも簡単である。特に,電気工事・配管工事は表面作業が可能となり、工数低減が可能となる。
○ 木材のみを用いた木造住宅のため、解体処理時における地球環境汚染防止・省資源に関し廃棄・リサイクル、更に林業の活性化、森林や治水の保存・環境保全に貢献できる。Since the present invention is a surface construction method using a thick plate member that has been steamed and dried, the following effects are obtained.
○ This construction method can counteract tensile stress by fixing the rigid body to the side plate with a plate, and counteracting shear stress between the log members using dowels and fixing the body to the side material. A load bearing wall can be constructed using log members in the work. The number of members is small, the wall construction method is simple, and even non-specialists can participate in this work, reducing the construction man-hours.
○ Although it is a wooden house that uses only wood, the surface components that occupy the majority of the building are stable and have excellent heat insulation and airtightness, combined with the heat storage effect of wood, it is comfortable with low heating and cooling power costs. Residential property can be secured.
○ Since no heat insulating materials or new building materials are used on the face walls, no harmful substances are released into the room, ensuring good comfort in terms of safety, health, humidity control and healing.
○ Since the wall surface is composed of one piece inside and outside, it is easy to monitor the wall surface and rehome easily. In particular, electrical work and piping work can be surface work, and man-hours can be reduced.
○ Because it is a wooden house that uses only timber, it can contribute to the prevention and conservation of global environmental pollution and resource conservation during demolition processing, further activation of forestry, conservation of forests and flood control, and environmental protection.
