Description

本発明は、例えば、一般住宅、集合住宅、ホテル、公共施設等の防火ドアとして用いられる木製防火ドア装置に関するものである。
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wooden fire door device used as a fire door for, for example, ordinary houses, collective housing, hotels, public facilities, and the like.

建築物においては、建築基準法施工令第１１２条における防火区画の規定及び耐火建築物または準耐火建築物の外壁の開口部で延焼の恐れのある部分の規定において、前者については、特定防火設備(旧甲種防火戸に相当)、後者の規定については、防火設備(旧乙種防火戸に相当)の設置が義務付けられている。
そして、現状では、特定防火設備のような性能を有する防火ドア及びドア枠材としては、鉄製が多く使用されている。 In buildings, in the provisions of fire protection compartments in Article 112 of the Building Standards Law Enforcement Ordinance and the provisions of openings in the outer walls of fire-resistant buildings or quasi-fire-resistant buildings where there is a risk of fire spreading, the former is specified as a specific fire prevention facility. (equivalent to the former class A fire door), and the latter provision requires the installation of fire prevention equipment (equivalent to the former class B fire door).
At present, steel is often used for fire doors and door frame materials that have performance similar to that of specific fire prevention equipment.

しかしながら、鉄製防火ドアについては以下のような課題が指摘されている。
すなわち、火災時に、熱変形によりドアが開かなくなり、人命救助、消火の妨げとなる。また、火災時には、火災発生の反対側のドア面の温度が数百度という高温となり、その輻射熱により近くの可燃物への着火の恐れを生じさせたり、退避する際の妨げとなるとの課題がある。
また、鉄製防火ドアは重量が極めて重くなってしまう。さらに、建築物のデザインによっては、ドアおよびドア枠の質感が異なり、意匠上、不具合を生じる場合が発生する。 However, the following problems have been pointed out for steel fire doors.
That is, in the event of a fire, the door cannot be opened due to thermal deformation, which hinders lifesaving and extinguishing. In addition, in the event of a fire, the temperature of the door surface on the opposite side of the fire will rise to a high temperature of several hundred degrees, and the radiant heat may ignite nearby combustibles and hinder evacuation. .
Also, steel fire doors are extremely heavy. Furthermore, depending on the design of the building, the door and the door frame may have different textures, which may cause problems in terms of design.

よって、このような課題を克服する手段のーつとして木質系防火ドアおよびドア枠が提案されるに至っている。 Therefore, wood-based fireproof doors and door frames have been proposed as one means of overcoming such problems.

ここで、木材は、一般的に、鉄に比較し、耐火性、防火性に劣ると言われている(特に薄くなるとこれは顕著となる)。そこで、木材の欠点を補い、耐火性、防火性を高める手段として、木材に薬剤を減圧含浸させ、木材そのものの耐火性、防火性を高める。また、不燃性材料と併用して耐火性、防火性を高めるなどのアイディアが提案されている。 Here, wood is generally said to be inferior to iron in fire resistance and fire resistance (this becomes more pronounced as the wood becomes thinner). Therefore, as a means of compensating for the drawbacks of wood and increasing fire resistance and fire resistance, wood is impregnated with a chemical agent under reduced pressure to increase fire resistance and fire resistance of wood itself. In addition, some ideas have been proposed to improve fire resistance and fire resistance by using them together with noncombustible materials.

しかし、実際に、木製の防火ドアを製作する場合において、木材に薬剤を減圧含浸し、木材そのものの耐火性、防火性を高めようとする場合では、設備的に特殊な含浸装置を必要とし、非常に高価な材料となる。よって木製の防火ドアとしても非常に高価となり市場性が狭く、限定した用途にのみ使用されることとなる。 However, in the actual manufacture of a wooden fire door, if it is desired to impregnate wood with a chemical agent under reduced pressure to increase the fire resistance and fire resistance of the wood itself, a special impregnation device is required in terms of equipment, It becomes a very expensive material. Therefore, even as a wooden fire door, it is very expensive, has a narrow marketability, and is used only for limited applications.

また、後者のように不燃性材料、例えば、ケイ酸カルシウム板、ロックウール断熱材などを併用して耐火性、防火性を高めようとする場合においては、建具としての実用面から框組が必須となる(框組がなく、ケイ酸カルシウム板、ロックウール断熱材などを併用すると著しく耐久性に劣るドアとなり、市場性がなくなる)。 In addition, as in the latter, when trying to improve fire resistance and fire resistance by using noncombustible materials such as calcium silicate board, rock wool insulation, etc., frame assembly is essential from the practical aspect of fittings. (If calcium silicate board, rock wool insulation, etc. are used together without a frame, the door will be significantly inferior in durability and will not be marketable.)

防火設備用ドア枠としては、楢、ブナ、ホワイトオークなどの高比重の材料を使用することも可能であるが、国内的には、木材資源の枯渇が進み、輸入するとしても、価格的に高止まり傾向にある。 It is possible to use materials with high specific gravity such as oak, beech, and white oak for fire prevention equipment door frames. It tends to stay high.

よって安価に、大量に入手できる材料を使用できるドア枠が求められている。
Therefore, there is a need for a door frame that is inexpensive and can use materials that are available in large quantities.

本発明によれば、木製の防火ドア装置であるにもかかわらず、鉄製の防火ドアに劣ることなく耐火性、防火性に優れ、しかも原材料が大量に入手でき、製造コストも安価にしうるとの優れた効果を奏する。
According to the present invention, although the fire door is made of wood, it is as good in fire resistance and fire resistance as iron fire doors. It works great.

以下、本発明の製造方法を図に基づいて説明する。
まず、本発明の木製防火ドア装置を製造する際に使用するべき部材から説明する。 The manufacturing method of the present invention will be described below with reference to the drawings.
First, the members to be used in manufacturing the wooden fire door apparatus of the present invention will be described.

防火ドア８の基本的な部材となるドア芯材用積層パネル１に使用する木製材料としては桐集成材などの板材が考えられる。桐集成材は比較的高温に耐えうる部材だからである。また、集成材であるため桐材であっても販売コストが安価である。 As a wooden material used for the door core laminated panel 1, which is a basic member of the fire door 8, a plate material such as laminated paulownia wood can be considered. This is because laminated paulownia wood is a member that can withstand relatively high temperatures. Also, since it is laminated wood, the sales cost is low even if it is paulownia wood.

次に、前記ドア芯材用積層パネル１の表裏面に貼着すべくシート状をなす耐熱性材料が使用される。前記パネルの表裏面に貼着され、耐火性、防火性を向上させるものとなる。 Next, a sheet-like heat-resistant material is used to be attached to the front and rear surfaces of the door core laminated panel 1 . It is attached to the front and back surfaces of the panel to improve fire resistance and fire resistance.

この耐熱性材料としては、耐熱性織物、耐熱性網類がある。
耐熱性織物としてはシリカ繊維、アルミナ繊維などの耐熱性繊維から作られた織物がある。耐熱性を有する金属性織物、網類としては鉄、ステンレス鋼、銅などの金属製織物、網がある。
なかでも比較的安価で入手しやすく、加工性に優れ、及び耐火性、防火性に優れたシリカクロス２が最適である。本発明ではシート状のシリカクロス２を使用している。 Heat-resistant materials include heat-resistant fabrics and heat-resistant nets.
Heat-resistant fabrics include fabrics made from heat-resistant fibers such as silica fibers and alumina fibers. Metal fabrics and nets having heat resistance include fabrics and nets made of metals such as iron, stainless steel and copper.
Among them, silica cloth 2 is most suitable because it is relatively inexpensive and readily available, has excellent workability, and has excellent fire resistance and fire resistance. In the present invention, sheet-like silica cloth 2 is used.

ここで、該シリカクロス２の織り方としては、平織り、綾織、朱子織などがある。織物の厚さは０．１ｍｍから１．５ｍｍ程度のものが適当である。
ここで、特定防火設備のように長時間の耐火性を要求される場合においては、綾織、朱子織のような緻密に織られた織物が好ましく、特に朱子織のものは隙間がなく織られており、耐火性に優れている。
また、その厚さは０．５～０．７ｍｍ程度が、価格、耐火、防火性、加工作業性などから最適である。 Here, the weaving method of the silica cloth 2 includes plain weave, twill weave, and satin weave. A suitable thickness of the woven fabric is about 0.1 mm to 1.5 mm.
Here, when long-term fire resistance is required, such as in specific fire prevention equipment, densely woven fabrics such as twill weave and satin weave are preferable. and has excellent fire resistance.
In addition, the thickness of about 0.5 to 0.7 mm is optimal from the viewpoint of price, fire resistance, fire resistance, workability, and the like.

金属製織物および網類は、製品そのものの剛性、反り、ねじれおよび一度付けられた折り目、凹凸等が入ると元に戻し難く、加工作業性が悪いことが指摘されている。 It has been pointed out that metal fabrics and nets are difficult to restore once they are bent, twisted, creases, unevenness, etc. due to the rigidity of the product itself, and have poor processing workability.

ところで、不燃紙、ケイ酸カルシウム板または加熱膨張性黒鉛を含有した加熱発泡性不燃紙を木質のドア芯材用の積層パネルと前記耐熱性織物の間に挿入することで防火ドアとしての耐火性、防火性を向上させることが可能となり、また防火ドアとしての厚さの低減を図れる効果がある。 By the way, by inserting noncombustible paper, calcium silicate plate, or heat-expandable noncombustible paper containing heat-expandable graphite between the laminated panel for the wooden door core material and the heat-resistant fabric, fire resistance as a fire door can be improved. , it is possible to improve the fire resistance, and there is an effect that the thickness of the fire door can be reduced.

従って、不燃紙、ケイ酸カルシウム板または加熱膨張性黒鉛を含有した加熱発泡性不燃紙は、本発明の防火ドア装置（防火ドアとドア枠材）の製造方法を行う上で使用することが好ましい。 Therefore, noncombustible paper, calcium silicate plate or thermally expandable noncombustible paper containing heat-expandable graphite is preferably used in carrying out the method of manufacturing the fire door device (fire door and door frame material) of the present invention. .

また、防火ドアおよびドア枠材として、前記耐熱性織物の上に化粧板、つき板合板、ダップ樹脂化粧板等の仕上げ材を接着、貼合するものとなり、これらの部材も製造上要求される部材である。 In addition, as a fire door and door frame material, a finishing material such as a veneer, veneer plywood, DAP resin veneer, etc. is adhered or laminated on the heat-resistant fabric, and these members are also required for manufacturing. It is a member.

さらに、防火ドアとしては高さ方向二辺に大手材を貼合し、錠前、ドアノブ、丁番を取り付けるための細部の加工を行っている。
他方、ドア枠においても、ドアと同様に耐火性織物の上から仕上げ材を接着、貼合し、錠前、丁番取り付けのための細部加工を行っている。
最後にドアとドア枠を丁番により合体させて、最終的に防火ドア装置として形成している。 In addition, as a fire door, large lumber is pasted on two sides in the height direction, and details are processed to attach a lock, doorknob, and hinge.
On the other hand, in the door frame, as with the door, finish materials are adhered and laminated on top of the fire-resistant fabric, and detailed processing is performed to attach locks and hinges.
Finally, the door and door frame are hinged together to finally form a fire door system.

使用する接着剤としては、酢酸ビニル系、エポキシ系、ウレタン系など一般的に使用されている合成樹脂系接着剤で充分である。
特に、木質系芯材とシリカクロス、アルミナクロスを接着する時、加熱発泡性黒鉛を含有した接着剤を使用すると、耐火性織物または網と木質系芯材との間に不燃紙等を挿入した場合と同様の効果が得られ、不燃紙等を挿入する必要がなくその分だけ防火ドアの厚さ低減が可能となる。 As the adhesive to be used, generally used synthetic resin adhesives such as vinyl acetate, epoxy, and urethane are sufficient.
In particular, when using an adhesive containing heat-expandable graphite when bonding a wood-based core material to silica cloth or alumina cloth, non-combustible paper or the like may be inserted between the fire-resistant fabric or net and the wood-based core material. The same effect as in the case can be obtained, and the thickness of the fire door can be reduced by that amount without inserting incombustible paper or the like.

接着剤用樹脂に対する加熱発泡性黒鉛の配合割合は、多ければ多い程、加熱発泡時の断熱性能は増すが、添加量に反比例し、接着力が低下する。よって必要とされる接着力を考盧して決定する。 As the blending ratio of heat-expandable graphite to the adhesive resin increases, the heat-insulating performance at the time of heat-expanding increases, but it is inversely proportional to the added amount, and the adhesive strength decreases. Therefore, the adhesive force required is considered and determined.

本発明による防火設備または特定防火設備は、鉄製の防火設備、特定防火設備に比較し、断熱性、遮音性に劣るものではなく、従来の木質系防火設備、特定防火設備に比較し安価に提供することが可能となる。 The fire prevention equipment or specific fire prevention equipment according to the present invention is not inferior in heat insulation and sound insulation compared to steel fire prevention equipment and specific fire prevention equipment, and can be provided at a lower price than conventional wooden fire prevention equipment and specific fire prevention equipment. It becomes possible to

またドア枠が木質系ドア枠であることにより、一般的木質系住宅において使用されるドアおよびドア枠と同等に取り扱えることから、一般住宅への耐火性、防火性の高い防火ドア装置の普及が促進できる。 In addition, since the door frame is a wooden door frame, it can be handled in the same manner as the doors and door frames used in general wooden houses. can promote.

ここで、本発明の実施例につき、図に基づいて説明する。
（第１実施例）
木製防火ドアの作製
一般に市販されている、例えば１３ｍｍの厚さで、９１０ｍｍ×１８２０ｍｍの大きさからなる桐集成材の板材を使用する。そして、これら桐集成材の板材を、例えば４枚、前記接着剤を用いて接着、貼合し、積層パネルとする。 An embodiment of the present invention will now be described with reference to the drawings.
(First embodiment)
Preparation of Wooden Fire Door A plate of paulownia glue laminated lumber having a thickness of 13 mm and a size of 910 mm×1820 mm, which is generally commercially available, is used. Then, for example, four sheets of paulownia laminated lumber are adhered and bonded together using the adhesive to form a laminated panel.

次いで、前記の積層パネルを、例えば９００ｍｍ×１,２００ｍｍに切断加工し、ドア芯材用積層パネル１とする。
さらに、上記切断加工したドア芯材用積層パネル１の表裏面に、例えばシート状をなす０．６ｍｍ程度の厚さのシリカクロス２を前記接着剤で接着、貼合する。
さらに、上記製作のシリカクロス２を接着したドア芯材用積層パネル１の四方向端面にシリカクロス２の端面を巻き込み、木口に接着加工する。 Next, the laminated panel is cut into, for example, 900 mm×1,200 mm to obtain the laminated panel 1 for door core material.
Further, a sheet-like silica cloth 2 having a thickness of about 0.6 mm, for example, is adhered and bonded to the front and back surfaces of the laminated door core panel 1 thus cut using the adhesive.
Further, the end faces of the silica cloth 2 are wrapped around the four end faces of the door core laminated panel 1 to which the silica cloth 2 is adhered, and the end face is adhered to the butt end.

この際、ドア芯材用積層パネル１の四方向端面に巻き込んだシリカクロス２は、重ねるか或いは、中央部で突き合わせて巻き込み加工して取り付ける。そして、例えば火災時のシリカクロス２の落下防止のために釘、ビス又はステープル等の取付具３でドア芯材用積層パネル１に留め付けておく。 At this time, the silica cloth 2 wrapped around the four end surfaces of the laminated panel 1 for door core material is attached by stacking it or by abutting it at the center and winding it. Then, for example, in order to prevent the silica cloth 2 from falling in the event of a fire, it is fastened to the door core laminated panel 1 with a fixture 3 such as a nail, a screw or a staple.

さらに、前記で製作したシリカクロス２を張ったドア芯材用積層パネル１の表裏面に、例えば２．５ｍｍ厚の化粧板４につき接着剤を用いて貼合する。
そして、接着した化粧板４を切断加工し、さらに長手方向二辺に大手材５(楢材３ｍｍ)を接着して防火ドアパネル６とする。 Further, a decorative panel 4 having a thickness of 2.5 mm, for example, is attached to the front and rear surfaces of the laminated door core panel 1 on which the silica cloth 2 prepared above is stretched, using an adhesive.
Then, the adhered decorative panel 4 is cut, and a fire door panel 6 is formed by adhering a large material 5 (3 mm oak material) to two sides in the longitudinal direction.

大手材５の中央部には、例えば、幅、１０ｍｍ、深さ、１ｍｍの溝を掘り、底に加熱膨張材７を埋め込む。
また、防火ドアパネル６の上、下端面には、中央部に幅１０ｍｍの加熱膨張材７をドア幅にわたり貼りつける。 A groove of, for example, 10 mm width and 1 mm depth is dug in the central portion of the large member 5, and the thermal expansion material 7 is embedded in the bottom.
Further, on the upper and lower end surfaces of the fire door panel 6, a heat expansion material 7 with a width of 10 mm is pasted on the central portion over the width of the door.

次いで防火ドアパネル６に錠前、ドアノブそして丁番等の取り付け加工を行い防火ドア８とする。
尚、前記シリカクロス２を上、下端及び高さ方向二辺で巻き込み加工を行ったが、部分的に不燃材等により耐火性補強を行えばシリカクロス２の巻き込み加工の必要はない場合も考えられる。 Next, a lock, a doorknob, a hinge, etc. are attached to the fire door panel 6 to form a fire door 8. - 特許庁
In addition, although the silica cloth 2 was wrapped at the upper and lower ends and two sides in the height direction, it may be possible that the silica cloth 2 does not need to be wrapped if the fire resistance is partially reinforced with a noncombustible material. be done.

次に、ドア枠１１の製造につき説明する。
防火ドア８と同様に、例えば、市販されている１３ｍｍの厚みで９１０ｍｍ×１８２０ｍｍの大きさの桐集成材で形成した板材６枚を接着剤を用いて貼合し積層パネルを形成する。 Next, manufacturing of the door frame 11 will be described.
As with the fire door 8, for example, six commercially available paulownia laminated lumber plates having a thickness of 13 mm and a size of 910 mm x 1820 mm are bonded together to form a laminated panel.

そして、この積層パネルより図２の形状による縦枠材９および図３に示す上枠材１０を製作すべく、所定の長さに切断する。
この際、防火ドア８とドア枠体１１との間隙が３～５ｍｍになる様な長さに切断する。 Then, the laminated panel is cut to a predetermined length in order to manufacture the vertical frame member 9 having the shape shown in FIG. 2 and the upper frame member 10 shown in FIG.
At this time, the length is cut so that the gap between the fire door 8 and the door frame 11 is 3 to 5 mm.

しかして、前記長さに切断した枠材(縦枠用２本、上枠用１本)の上端、下端の２面を除くＬ字型を形成する６面に接着剤を用いてシリカクロス２を接合する。
この際、シリカクロス２にしわ、よじれ等が入らぬように補助板等を使用して貼合する。 Then, silica cloth 2 was applied to the six sides forming an L-shape except for the upper and lower ends of the frame members (two for the vertical frame and one for the upper frame) cut to the above length using an adhesive. to join.
At this time, an auxiliary plate or the like is used to prevent the silica cloth 2 from being wrinkled or twisted.

次いで、シリカクロス２の貼合面に、さらに化粧板４(２．５ｍｍ)を接着し仕上げとする。その際、防火ドア８と相対する面の化粧板４には、幅２０ｍｍ、深さ１ｍｍの溝をつけ、該溝に膨張黒鉛性発泡材を埋め込んでおく。 Next, a decorative plate 4 (2.5 mm) is further adhered to the bonding surface of the silica cloth 2 for finishing. At this time, a groove having a width of 20 mm and a depth of 1 mm is formed in the decorative plate 4 facing the fire door 8, and the expanded graphite foam material is embedded in the groove.

ドア枠材(縦枠用２本、上枠用１本)を用いて図のようにコ型に組み立てる。縦枠材９と上枠材１０の結合には、接着剤とビスを併用して結合する。
前記ドア枠１１に錠前、丁番等の取り付け加工を施した後、前記製作した防火ドアを取り付け防火ドア装置とする。取り付けの際、防火ドア８とドア枠１１との間隙は３～５ｍｍとなる様に取り付ける。
尚、ドア枠１１の作製方法としては、分割して作製後に一体化しても差し支えない。 Using the door frame materials (2 for the vertical frame and 1 for the upper frame), assemble in a U-shape as shown in the figure. The vertical frame member 9 and the upper frame member 10 are joined together using an adhesive and screws.
After the door frame 11 is processed to attach locks, hinges, etc., the manufactured fire door is attached to form a fire door device. At the time of installation, the fire door 8 and the door frame 11 are installed so that the gap between them is 3 to 5 mm.
In addition, as a method of manufacturing the door frame 11, it is possible to divide the door frame 11 and integrate it after manufacturing.

前記積層パネルの表裏面に、２ｍｍ厚の不燃紙を接着する。
この積層パネルを９００ｍｍ×１,２００ｍｍの大きさに切断加工し、ドア芯材用積層パネル１とする。 (Example 2)
For example, four laminated paulownia wood sheets with a thickness of 9 mm are adhered with an adhesive to form a laminated panel.
Noncombustible paper with a thickness of 2 mm is adhered to the front and back surfaces of the laminated panel.
This laminated panel is cut into a size of 900 mm×1,200 mm to obtain a laminated panel 1 for door core material.

切断加工したドア芯材用積層パネル１の表裏面に１．０ｍｍ厚のシリカクロス２を接着剤で接着する。
