Pile up. The form of stacking is not limited to this, and many forms can be considered. The shape of the crosspiece used is not limited to the long rectangular cross section shown in the example shown, but can also be approximately cubic. good. When stacked together, ventilation spaces are created between the timbers, allowing for artificial or natural drying. It is not limited to a specific shape as long as it is configured so as to fit. In addition, the material used for the crosspiece is Often made of wood, iron, aluminum, etc.
【０００３】 しかしながら、現在使用されている桟には以下にまとめて示すような問題点が ある。 (1) 乾燥ムラが出る。 (2) 変色が出る。 (3) 汚れが付着する。 (4) 割れが出る。 (5) 時間がかかる。 (6) 不良率が高い。 (7) 変形が出る。 (8) 乾燥コストが高い。 (9) カビが生え易い。0003 However, the currently used crosspieces have the following problems: be.

本考案者らは、上記目的を実現すべく種々検討を重ねた結果、遠赤外線を放射 する材料で桟を構成することによって効果的な乾燥が行われることを知り、本考 案を完成した。 すなわち、本考案によれば、遠赤外線波長２〜100 μm の放射率が80％以上と なるような電磁波放射機能を持つ桟を使用することによって、前記従来技術の問 題点を解決しようとするのである。 As a result of various studies to achieve the above purpose, the inventors of the present invention emitted far-infrared rays. We learned that effective drying can be achieved by constructing the crosspiece with a material that Completed the draft. In other words, according to the present invention, the emissivity at far infrared wavelengths of 2 to 100 μm is over 80%. By using a crosspiece with an electromagnetic wave radiation function, the problems of the prior art can be solved. They try to solve problems.
【０００７】 より具体的には、本考案によれば、木材の桟積みに使用される木材乾燥用の桟 を、セラミックを混入したポリエチレン系樹脂、ポリプロピレン系樹脂、もしく は繊維強化プラスチック(F.R.P) で成形するか、あるいは、木材、鉄、もしくは アルミニウムから形成した桟にセラミックをコーティングすることによって、遠 赤外線放射体としての桟を構成するのである。 本考案の好適態様によれば、上記桟は、積み上げる木材との接触を線接触ある いは点接触とすべく、その外周を波形に成形するとともに、短期温度上昇をはか るためにその内部を中空としてもよい。[0007] More specifically, the present invention provides a timber drying rack used for stacking timber. , polyethylene resin mixed with ceramic, polypropylene resin, or may be molded from fiber-reinforced plastic (F.R.P) or made from wood, steel, or By coating the crosspiece made of aluminum with ceramic, it is possible to It constitutes a crosspiece as an infrared radiator. According to a preferred embodiment of the present invention, the crosspiece makes contact with the timber to be piled up by a line contact. In order to make point contact, the outer periphery is shaped into a corrugated shape, and measures are taken to prevent short-term temperature rise. The inside may be made hollow in order to
【０００８】[0008]
次に、添付図面を参照して本考案にかかる桟の構造およびその作用についてさ らに詳述する。 図１は、本考案に桟10を示す図面であって、図１(a) は正面図、そして図１(b ) は側面図である。 図中、全体が断面矩形の長尺体をなす桟10の外周には波形12が全面にわたって 設けられており、この場合には桟積みしたとき木材( 図示せず）との接触は線接 触となる。桟10の中心には中空部14が設けられている。この中空部14の大きさは 桟10としての機械的強度が確保される限り、より大きな通気量を確保するために は大きいのが好ましい。 Next, the structure and function of the crosspiece according to the present invention will be explained with reference to the attached drawings. This will be explained in detail below. FIG. 1 is a drawing showing the crosspiece 10 of the present invention, FIG. 1(a) is a front view, and FIG. 1(b) is a front view. ) is a side view. In the figure, a waveform 12 is formed all over the outer periphery of the crosspiece 10, which is an elongated body with a rectangular cross section. In this case, the contact with the timber (not shown) is tangential when stacked. It becomes a touch. A hollow portion 14 is provided at the center of the crosspiece 10. The size of this hollow part 14 is To ensure greater ventilation as long as the mechanical strength as crosspiece 10 is ensured is preferably large.
【０００９】 なお、乾燥すべき木材との接触を点接触とするには、桟外表面に多数の突起を 設け、それによって木材を支持するようにする。 上述のように遠赤外線を放射するセラミックとしては、既に周知のものを使用 すればよく、例えばAl2O3 、SiO2、TiO2、Fe203 、ZrO2などを混入するか、適宜 バインダーとともに表面に塗布すればよい。場合によってはさらに焼結処理を行 い一定の強度を確保し、桟積み時の圧壊を防止するようにしてもよい。[0009]In order to make point contact with the wood to be dried, a large number of protrusions are provided on the outer surface of the crosspiece to support the wood. As mentioned above, as the ceramic that emits far infrared rays, it is sufficient to use a well-known ceramic, for example, by mixing Al 2 O 3 , SiO 2 , TiO 2 , Fe 2 0 3 , ZrO 2 or the like, or adding a binder as appropriate. It can be applied to the surface along with the Depending on the case, a sintering treatment may be further performed to ensure a certain level of strength and prevent crushing during stacking.
【００１０】 本考案によれば、遠赤外線波長２〜100 μm の放射率が80％以上になるように 上記セラミックを混入、塗布するが、これは遠赤外線としての効果に優れている のは波長２〜100 μm の範囲の電磁波であって、その放射率が80％以上でないと いわゆる木材の乾燥には十分でないためである。しかし、この程度の遠赤外線の 放射は例えばAl2O3 系セラミックをほぼ２〜30％配合するだけで、あるいは単に 塗布するだけで達成できる程度である。 ここに、放射率とは、理想黒体を基準とし、個々の物体の放射特性を測定する ことによって求められる値である。According to the present invention, the above-mentioned ceramic is mixed and coated so that the emissivity at far infrared wavelengths of 2 to 100 μm is 80% or more; This is because it is an electromagnetic wave in the range of 2 to 100 μm, and unless its emissivity is 80% or more, it is not sufficient to dry wood. However, this level of far-infrared radiation can only be achieved by adding about 2 to 30% of Al 2 O 3 based ceramics or simply by coating. Here, the emissivity is a value obtained by measuring the radiation characteristics of each object using an ideal black body as a reference.
【００１１】 図２は、本考案にかかる桟10を使用した木材20の桟積みの様子を示す略式斜視 図であって、前述の図３と比較して、遠赤外線放射体として構成した桟10を使用 している点を除いて両者は同一である。 図２の場合、乾燥すべき木材は、電磁波を放射する本考案にかかる桟10で桟積 されている。この桟10から放射される電磁波が木材に含まれる水分および周囲の 水分に反応し、水分の拡散、移動を促進する。 さらに、桟10が中空に成形されている場合には、桟10自体の効率よい温度上昇 が図れる。そのため、桟10の内部の水分を外部へ気化放出させ易くする。この働 きは乾燥時間を大幅に短縮させる。しかも、遠赤外線放射型の桟10が桟積みの内 部まで行き届いているため、木材の乾燥ムラが出ない。また、電磁波の作用で表 面乾燥を防ぐので、割れも発生し難い。さらに、これらの総合的作用によって含 水率分布のムラによる変形も防ぐことができる。[0011] FIG. 2 is a schematic perspective view showing how timber 20 is piled up using the crosspiece 10 according to the present invention. In this figure, compared to the above-mentioned figure 3, a crosspiece 10 configured as a far-infrared radiator is used. Both are the same except that In the case of Fig. 2, the wood to be dried is piled up on the crosspiece 10 according to the present invention that emits electromagnetic waves. has been done. The electromagnetic waves radiated from this crosspiece 10 are absorbed by the moisture contained in the wood and the surrounding area. Reacts with moisture and promotes moisture diffusion and movement. Furthermore, when the crosspiece 10 is formed hollow, the temperature of the crosspiece 10 itself can be increased efficiently. can be achieved. Therefore, the moisture inside the crosspiece 10 is easily vaporized and released to the outside. This work This greatly reduces drying time. Moreover, the far-infrared radiation type crosspiece 10 is inside the crosspiece. The wood is thoroughly dried, so there is no uneven drying of the wood. Also, it can be expressed by the action of electromagnetic waves. Since it prevents surface drying, cracking is less likely to occur. In addition, these comprehensive effects Deformation due to uneven water rate distribution can also be prevented.
【００１２】 本考案の好適態様に示すように遠赤外線放射型の桟10が図１のように外周に波 形を有する場合、乾燥すべき木材との接触部が線となり、通気性がさらに改善さ れるので接触部の乾燥遅れ、それに伴う乾燥速度の差による変形も起きない。 このようにして本考案にかかる遠赤外線放射型の桟によって桟積みされた木材 は天然乾燥されても、あるいは乾燥装置によって熱風を送ってもしくは大型乾燥 炉内に装入して人工的に乾燥してもよい。0012 As shown in a preferred embodiment of the present invention, a far-infrared radiation type crosspiece 10 has waves on the outer periphery as shown in FIG. If the material has a shape, the contact area with the wood to be dried becomes a line, further improving breathability. Therefore, there is no delay in the drying of the contact area and no deformation due to the resulting difference in drying speed. Wood stacked in this way using the far-infrared radiation type crosspiece according to the present invention may be dried naturally, or by blowing hot air with a drying device or drying on a large scale. It may also be placed in a furnace and dried artificially.

このように本考案によれば、従来とかく問題の多かった木材の乾燥が効果的に しかも短時間で行うことができるようになったのであり、特に最近のように省力 化、合理化が強く求められている木材産業のような伝統的産業分野における意義 は大きい。 In this way, according to this invention, drying of wood, which has traditionally had many problems, can be effectively done. Moreover, it has become possible to do it in a short time, especially in recent years, which saves labor. Significance in traditional industrial fields such as the timber industry, where there is a strong need for optimization and rationalization. is big.
