Description

本発明は、耐火剤処理液を含浸した桐材を用い、防火性に優れた桐材を用いた防火ドアに関するものである。   The present invention relates to a fireproof door using a paulownia material impregnated with a fireproofing agent treatment liquid and using a paulownia material excellent in fireproofing property.

従来、高層建築物、デパート、ホテルなどの大勢の利用者が集積しやすい施設においては、一度火災が発生すると甚大な被害が予想されることから、消防法により防火ドアを備えることが義務づけられている。これにより、万一火災が発生した場合であっても延焼防止により、最小限の被害に止められるよう配慮されている。また、実際に火災が発生した場合には、その熱によって環境は数百度以上の温度となるため、防火ドアに求められる性能としては、遮炎性、遮煙性、遮熱性、耐熱性等が挙げられている。そこで、従来防火ドアとしては、金属製のものが広く普及している。   Conventionally, in facilities where large numbers of users, such as high-rise buildings, department stores, hotels, etc., are likely to accumulate, once a fire breaks out, it is expected to cause tremendous damage. Yes. As a result, even if a fire breaks out, consideration is given to minimizing damage by preventing the spread of fire. In addition, when a fire actually occurs, the temperature of the environment becomes several hundred degrees or more due to the heat, so the performance required for fire doors is flameproof, smokeproof, heatproof, heat resistant, etc. Are listed. Therefore, metal fire doors are widely used.

一方、近年、木材を主体とした木製ドアが脚光を浴びている。これは、木製独特の木目模様の美観、熱伝導率が低いという素材的特徴、加工の容易さ等といった点が再評価されたためと考えられる他に、国土交通大臣の認定を受けることによって、耐火建築物・準耐火建築物の防火ドアとして使用できるようになったという背景も認められる。   On the other hand, in recent years, wooden doors mainly made of wood have attracted attention. This is thought to be due to the re-evaluation of the aesthetic appearance of the wood pattern unique to wood, the material characteristics of low thermal conductivity, ease of processing, etc. There is also a background that it can be used as a fire door for buildings and semi-fireproof buildings.

そこで、木製防火ドアに関する発明として、特開平7−293127号が挙げられる。当該発明は、ドアを構成する主要部材となる芯材に、歪が生じにくく比重の小さい難燃性の桐材を用い、木製防火ドアを軽量化すると共に、建物が火災にあった際に、木製防火ドアがその芯部まで完全燃焼し尽くしたり大きく歪んだりするのを防ぐものであり、上記芯材の表裏面には不燃紙を介して、化粧板をそれぞれ貼着し、上記不燃紙で木製防火ドアの耐火性を高めるようにしたものである。また、上記発明の特徴的な効果は、従来の金属製の防火ドアに比べ
断然軽量であることが挙げられる。ここで、防火ドアの外周囲に金属製枠を固定したものは、耐熱性の点では問題はないが、必然的に重いという欠点がある。特に、通常のドアは回転可能な蝶番を中心軸にして開閉するため、中心軸の回りの慣性モーメントの大小がドアの操作性に大きく影響している。即ち、ドアの慣性モーメントは、中心軸から質点までの距離の二乗に比例している。よって、ドアの外周面に重量物を固定するほど、ドアの開け閉めの際の操作性が悪化するという課題があった。
特開平7−293127号
Japanese Patent Laid-Open No. 7-293127 is an example of an invention related to a wooden fire door. The invention uses a flame-resistant paulownia material that is less likely to be distorted and has a small specific gravity for the core material that constitutes the door, reducing the weight of the wooden fire door, and when the building is in fire, The wooden fire door is designed to prevent the core from being completely burned up to the core or being greatly distorted, and a decorative board is attached to the front and back surfaces of the core material via non-combustible paper. This is to improve the fire resistance of wooden fire doors. Further, the characteristic effect of the present invention is that it is lighter than the conventional metal fire door. Here, what fixed the metal frame to the outer periphery of the fire door has no problem in terms of heat resistance, but has a drawback that it is necessarily heavy. In particular, since a normal door opens and closes around a rotatable hinge as a central axis, the magnitude of the moment of inertia around the central axis greatly affects the operability of the door. That is, the moment of inertia of the door is proportional to the square of the distance from the central axis to the mass point. Therefore, the problem that the operability at the time of opening and closing the door deteriorates as the heavy object is fixed to the outer peripheral surface of the door.
JP-A-7-293127

一方、上記特開平7−293127号に係る発明に中で、芯材として選択された桐はゴマノハグサ科の落葉高木であり、その特徴は成長が早く、幹は高さ10mにも達するものである。また、桐材は比重が0.31と樹木の中で最も軽く、木目が美しく、材としての狂いが少ないことが特徴と考えられる。更に、充分に乾燥処理した桐材は伸縮率・収縮率が小さく、湿度の通過性や熱伝導率がきわめて小さいという特性を有しているため、古来からその用途としては箪笥、刀剣、掛け軸など高級貴重品を収納するための箱、琴・琵琶等の楽器、下駄等の日用品に至るまで広範囲な使用が成されている。ここで、桐材の熱伝導性と吸水性に係る独特な特徴は、桐の導管の構造に理由があることが研究によって判明している。即ち、普通の木材は導管が木の成長方向に形成されると共に互いに絡み合い干渉し合っている構造となっているが、これに対して桐は木の成長方向に対して垂直に連続した袋状の導管を形成していると共に導管同士の干渉がない独立した構造となっている。ここで、上記連続した袋状の導管内には空気や水分等が溜め込まれている。このような特殊な構造であるが故、桐材は一般の木材に比べ乾燥時間が約3倍程も要す結果となっている。また、桐材の熱伝導率は、0.063Kcal/mh°Cであって、パーティクルボードを構成するブナ、マカンバ、ミズナラ、ケヤキ等の通常汎用される木材の熱伝導率の0.117〜0.123Kcal/mh°Cに比べても大幅に低く、このことは桐材が熱を伝え難いことを示している。更に、桐材は耐火性にも優れており、その発火点は400°C以上といわれており、仮に着火した場合にも炭化することから、燃え難いという性質をもっている。   On the other hand, the paulownia tree selected as the core material in the invention according to the above-mentioned Japanese Patent Application Laid-Open No. 7-293127 is a deciduous tree of the scorpion family, whose characteristics are fast growth and the trunk reaches a height of 10 m. . In addition, paulownia has the specific gravity of 0.31 and is the lightest among the trees, has a beautiful grain, and is considered to be characterized by little deviation as a material. Furthermore, paulownia wood that has been thoroughly dried has characteristics such as low stretch and shrinkage, and extremely low humidity permeability and thermal conductivity. It is used in a wide range of applications, including boxes for storing high-class valuables, musical instruments such as kotos and koto, and daily necessaries such as clogs. Here, research has revealed that the unique characteristics of the paulownia wood's thermal conductivity and water absorption are due to the structure of the paulownia conduit. In other words, ordinary timber has a structure in which conduits are formed in the growth direction of the tree and entangled with each other to interfere with each other, whereas paulownia has a continuous bag shape perpendicular to the growth direction of the tree. It is an independent structure which forms the conduit of the above and has no interference between the conduits. Here, air, moisture and the like are stored in the continuous bag-shaped conduit. Because of this special structure, paulownia wood requires about three times as much drying time as ordinary wood. Moreover, the thermal conductivity of the paulownia wood is 0.063 Kcal / mh ° C., which is 0.117 to 0 of the thermal conductivity of commonly used wood such as beech, mackerel, mizunara, and zelkova that constitute the particle board. This is significantly lower than that of 123 Kcal / mh ° C., indicating that the paulownia is difficult to conduct heat. Furthermore, paulownia has excellent fire resistance, and its ignition point is said to be 400 ° C. or higher, and since it carbonizes even when ignited, it has the property of being difficult to burn.

更に、本発明者らは、桐材の不燃化に対する研究において、含水率を9%以下に十分乾燥させた桐材を減圧条件下で防火薬剤に浸漬した後、防火薬剤に浸漬したまま所定圧毎に段階的に加圧を行なう方法によって、桐材に対する防火薬剤の含浸作用が極めて有効に改善され不燃性が付与されると共に桐材としての美観溢れる木肌を維持した桐材が得られるとの知見を得ている。具体的に、その防火性桐材は、桐材を乾燥して含水率9%以下と成した後、当該桐材を液温40〜70°Cの耐火剤溶液中に減圧下30〜40torrで6〜12時間浸漬し、次に常圧に戻し、その後所定圧力毎に段階的に圧力を付与し最高10気圧まで加圧した状態で6〜12時間浸漬して、続いて上記桐材を上記耐火剤液から取り出し、常温で20〜30日間乾燥させ、更にまた50〜80°Cで6〜12時間乾燥して、含水率を18%以下となしたものである。   Furthermore, the inventors of the present invention, in research on the incombustibility of paulownia wood, immerse the paulownia wood sufficiently dried to a moisture content of 9% or less in a fireproofing agent under reduced pressure conditions, and then immerse in the fireproofing agent at a predetermined pressure. By the method of applying pressure step by step every time, the impregnation action of the fireproofing agent on the paulownia wood is extremely effectively improved, nonflammability is imparted, and the paulownia wood that maintains the beautiful wood surface as the paulownia wood is obtained. We have knowledge. Specifically, the fireproof paulownia is made by drying the paulownia wood to a moisture content of 9% or less, and then the paulownia wood in a refractory solution having a liquid temperature of 40 to 70 ° C. under reduced pressure at 30 to 40 torr. Immerse for 6-12 hours, then return to normal pressure, then apply pressure stepwise for each predetermined pressure and soak for 6-12 hours under pressure up to 10 atm. It is taken out from the refractory solution, dried at room temperature for 20 to 30 days, and further dried at 50 to 80 ° C. for 6 to 12 hours to obtain a water content of 18% or less.

上記背景技術の項に記載の特開平7−293127号に関する木製防火ドアは、桐の小片木や桐の間伐材を寄せ集めてなる集成材や桐の板材をドアの芯材に用い、当該芯材の表裏面にノンアスベストの無機シート等の不燃紙を介して化粧板を貼着したものとされている。また、このようにして製作された木製防火ドアは、高さ2,100mm×幅900〜950mm×厚さ40〜43mmの通常の大きさのもので、その重量を36kg程度まで軽量化することができると記載されているが、未だ過重量でありドアの開閉の際の操作性が悪いという課題がある。更に、上記木製防火ドアは防火ドアとしての防火性能についても満足される域には至っていないとの課題がある。そこで、本発明は上記従来技術の課題等に鑑みる共に、上記記載の本発明者らの桐材の不燃化に対する継続的研究に基く種々の知見から成されたものであり、その目的とするところは、開閉時の操作性が良好な軽量な木製ドアであると共に、優れた防火性能が具備されている他、外観においても桐材における木目模様の美観を有した桐材を用いた防火ドアを提供することにある。   The wooden fire prevention door related to Japanese Patent Application Laid-Open No. 7-293127 described in the Background section above uses laminated timber made of paulownia timber pieces and paulownia thinned wood or paulownia plate material as the door core material. A decorative board is attached to the front and back surfaces of the material through non-combustible paper such as a non-asbestos inorganic sheet. In addition, the wooden fire door manufactured in this way has a normal size of 2,100 mm in height, 900 to 950 mm in width and 40 to 43 mm in thickness, and its weight can be reduced to about 36 kg. Although described as being possible, there is still a problem that it is excessively heavy and the operability when opening and closing the door is poor. Furthermore, there is a problem that the wooden fire door does not reach an area where the fire performance as a fire door is satisfied. Therefore, the present invention has been made in view of the above-mentioned problems of the prior art, and has been made from various findings based on the above-described continuous research on the incombustibility of the paulownia materials by the present inventors.
