Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は家屋における屋根材の下地材として用いられる
野地板およびその製造方法に関する。TECHNICAL FIELD The present invention relates to a base plate used as a base material for a roof material in a house and a method for manufacturing the same.
一般に屋根の野地板として平面平滑な合板、繊維板が用
いられた。In general, flat and smooth plywood and fiberboard were used as roof boards.
しかしながら、上記従来の野地板は保温性が低いため、
屋根裏あるいは天井裏に厚い繊維マットなどを別々に敷
くことを行なわれており、作業性の低下はもちろん、コ
スト高の原因となっていた。However, since the above-mentioned conventional baseboard has low heat retention,
Thick fiber mats are laid separately in the attic or attic, which not only lowers workability but also causes high cost.
また板表面が平滑面であり、屋根構造下地に釘打ちなど
によって施工されるが、傾斜面であるため、施工した板
面が非常に滑り易く、該板の施工時又施工した板上にア
スァルトフェルト、ルーフィングなどの防水材の施工
時、滑りによる屋根資材、作業者の落下の危険性があっ
た。Also, the plate surface is a smooth surface and is constructed by nailing on the roof structure foundation, but since it is an inclined surface, the constructed plate surface is very slippery, and there is no asphalt during the construction of the plate or on the constructed plate. There was a risk of falling roof materials and workers due to slippage when constructing waterproof materials such as Altfeld and roofing.
本発明は上記のような従来の野地板の問題点を解決する
ため次のような構成をとったものである。The present invention has the following constitution in order to solve the problems of the conventional ground plate as described above.
すなわち、本発明野地板は芯部ａに比し、表裏面に高比
重部ｂを有する木質繊維板を基板とし、その少なくとも
片側表面に保温用凹部ｃを設けたものである。That is, the base plate of the present invention uses a wood fiberboard having a high specific gravity portion b on the front and back surfaces as a substrate, as compared with the core portion a, and has a heat insulating recess c provided on at least one surface thereof.
本発明の野地板は上記構成をとることにより、保温性が
良くて、屋根裏あるいは天井裏に繊維マットなどを必要
とせず、かつ、作業者の落下の危険性の少ない野地板を
提供し得たものである。The field board of the present invention, having the above-described configuration, can provide a field board that has good heat retaining properties, does not require a fiber mat or the like in the attic or the attic, and has a low risk of a worker falling. It is a thing.
以下本発明の実施例について説明する。 Examples of the present invention will be described below.
基板としては、芯部ａに比して高比重部ｂの表裏面を有
する木質繊維板を用いる。As the substrate, a wood fiber board having front and back surfaces of the high specific gravity portion b as compared with the core portion a is used.
木質繊維板は芯部の比重が0.3 〜0.7 表裏面の比重が
0.7〜1.3 の範囲にあることが好ましく、またその全体
比重として0.5 〜1.0 が適当であり芯部、表裏部の比重
差が0.2 以上であることが好ましい。Wood fiberboard has a core specific gravity of 0.3 to 0.7
The specific gravity is preferably in the range of 0.7 to 1.3, the total specific gravity thereof is preferably 0.5 to 1.0, and the specific gravity difference between the core portion and the front and back portions is preferably 0.2 or more.
表裏面に高比重部ｂが形成されるためサンドイッチ効果
によって十分に強度が得られ、その芯部ａの比重を下げ
ることができ、また結果として、全体比重を下げること
ができる。したがって、持ち運び、施工性が容易とな
る。この場合全体比重が0.5 以下であると、強度が低
く、1.0 以上であると重くなってしまい、持ち運び、施
工性に困難を感ずる。Since the high specific gravity portion b is formed on the front and back surfaces, sufficient strength can be obtained by the sandwich effect, the specific gravity of the core portion a can be reduced, and as a result, the overall specific gravity can be reduced. Therefore, it is easy to carry and construct. In this case, if the overall specific gravity is 0.5 or less, the strength will be low, and if it is 1.0 or more, it will be heavy, making it difficult to carry and workability.
芯部ａ、高比重部ｂの比重下が0.2 以下であると全体比
重が高くなるだけで強度向上にはならない。If the specific gravity of the core portion a and the high specific gravity portion b is 0.2 or less, the overall specific gravity is increased and the strength is not improved.
また、それら芯部ａと表裏高比重部ｂの厚さ方向の厚さ
割合は１：１〜５：１とすることが好ましい。Further, the thickness ratio of the core portion a and the front and back high specific gravity portions b in the thickness direction is preferably 1: 1 to 5: 1.
厚さ割合がこの範囲外であると、高比重部ｂが多くな
り、板自体が重く施工性が悪く、逆に高比重部が少なく
なり、サンドイッチ効果が期待できない。When the thickness ratio is out of this range, the high specific gravity portion b increases, the plate itself is heavy and the workability is poor, and conversely, the high specific gravity portion decreases, and the sandwich effect cannot be expected.
また基板の表裏面の高比重部の少なくとも片側表面に切
削加工、エンボス加工などによって複数の保温用凹部ｃ
を形成する。In addition, a plurality of heat retaining recesses c are formed by cutting or embossing on at least one surface of the high specific gravity portion on the front and back surfaces of the substrate.
To form.
保温用凹部ｃはその大きさ又断面形状は何等限定される
ものではないが、その凹部ｃの開口面積が表面積に比し
て６０％以下とすることが好ましい。Although the size or cross-sectional shape of the heat retaining recess c is not limited in any way, the opening area of the recess c is preferably 60% or less of the surface area.
６０％以上であると凹部空気層割合が高くなり、保温性
は向上されるが逆に強度低下となってしまう。If it is 60% or more, the proportion of the air layer in the recesses becomes high, and the heat retaining property is improved, but the strength is decreased.
また凹部形成による内部応力バランスがくずれてしまう
ため、凹部側を凹とした反りの発生が非常に大きく発生
してしまう。In addition, since the internal stress balance due to the formation of the concave portion is lost, the warp in which the concave portion side is concave is extremely large.
さらに、高比重部ｂに形成された保温用凹部ｃを含む表
全面に合成樹脂、ラテックス、アスファルトなどを塗布
または含浸して防水層ｄを形成する。この場合防水層ｄ
を形成する合成樹脂、ラテックス、アスファルトなどに
は炭カル、珪砂、アルミナなど無機骨材を混合してもよ
い。Further, a waterproof layer d is formed by applying or impregnating synthetic resin, latex, asphalt or the like on the entire front surface including the heat insulating recess c formed in the high specific gravity portion b. In this case waterproof layer d
Inorganic aggregates such as calcium carbonate, silica sand, and alumina may be mixed with the synthetic resin, latex, asphalt, etc. forming the.
防水層ｄを形成することによって雨漏などによる雨水の
基板へ浸透を防止する。By forming the waterproof layer d, the permeation of rainwater into the substrate due to rain leakage or the like is prevented.
以上の如くして表面の裏比重部に保温用凹部を形成され
た木質繊維板からなる野地板を得た。As described above, a base plate made of a wood fiberboard having a heat retaining recess formed in the back specific gravity portion of the surface was obtained.
該野地板の施工においては、木等の屋根構造下地材上に
野地板の保温用凹部を表面側として釘打ちによって施工
し、次にその表全面にアスファルトフェルト、アスファ
ルトルーフィングなど防水シートを敷詰めた後屋根材を
施工する。In the construction of the base plate, the heat insulating recess of the base plate is nailed on the roof structure base material such as wood as the surface side, and then a waterproof sheet such as asphalt felt or asphalt roofing is spread over the entire surface. After installing the roof material.
本発明野地板と防水シートとの間に凹部空気層が形
成され、保温効果が向上され保温材料を薄いものとする
ことができる。また木質繊維板は木質粒子のマスである
ため、全体として均一な比重が得られ、保温効果も均一
になり、結果的に保温効果が合板などの他の素材に比べ
高い。A concave air layer is formed between the base plate of the present invention and the waterproof sheet, the heat insulating effect is improved, and the heat insulating material can be made thin. Moreover, since the wood fiberboard is a mass of wood particles, a uniform specific gravity is obtained as a whole, and the heat retaining effect is also uniform, and as a result, the heat retaining effect is higher than other materials such as plywood.
また該凹部外の凸部は高比重部で形成されるため持
ち運び、施工時に損傷されることがなく、その凸部が滑
り止め効果をもはたす。また保温用凹部の刻設もし易
い。Further, since the convex portion outside the concave portion is formed of a high specific gravity portion, it is carried and is not damaged during construction, and the convex portion has a non-slip effect. In addition, it is easy to engrave the heat insulating recess.
図面は本発明野地板の断面図を示す。 ａ：芯部、 ｂ：高比重部、 ｃ：保温用凹部。 The drawing shows a cross-sectional view of the inventive ground plate. a: core part, b: high specific gravity part, c: heat retaining recess.
