Description

本発明は、反りや歪みを生じることが少なく、吸音性、遮音性、断熱性に優れたハニカムコアドア及びその製造方法に関するものである。   The present invention relates to a honeycomb core door that is less likely to be warped or distorted and has excellent sound absorbing properties, sound insulating properties, and heat insulating properties, and a method for manufacturing the same.

特許文献１によれば、図８に示すごとく、断面略波状の形成板９を板状物８に接着剤を介して平面板（フランジ）８に接合した「木質系軽量横架材」が開示されている。   According to Patent Document 1, as shown in FIG. 8, a “woody lightweight horizontal member” is disclosed in which a forming plate 9 having a substantially corrugated cross section is joined to a flat plate (flange) 8 via an adhesive to a plate-like object 8. Has been.

上記波状の成形板９は、「ウェブとしての湾曲凹面部９１と湾曲凸面部９２とからなり、軽量で安価で座屈強度が大きいものであると開示されている。ウェブの素材は植物片、好ましくは粉末状、繊維状、チップ状の木材からなるものである」ことが開示されている。   The wavy shaped plate 9 is disclosed as “consisting of a curved concave surface portion 91 and a curved convex surface portion 92 as a web, and is lightweight, inexpensive and has high buckling strength. The material of the web is a plant piece, “It is preferably made of powdered, fibrous, or chip-shaped wood”.

そして、特許文献１には、図９に示すごとく、ウェブ９１、９２は、金型形成プレス７を用いて製造されることが特許文献１における図５により、具体的に開示されている。   In Patent Document 1, as shown in FIG. 9, it is specifically disclosed in FIG. 5 in Patent Document 1 that the webs 91 and 92 are manufactured using the mold forming press 7.

一方、特許文献２によれば、図１０に示すごとく、防音ドア９の中空部内に断面略波状の吸音材９３と遮音シート９４とが配設されている（特許文献２の図１参照）。
特開平１１−３６５１４号公報 特開２００２−８９１４２号公報 On the other hand, according to Patent Document 2, as shown in FIG. 10, a sound absorbing material 93 and a sound insulating sheet 94 having a substantially wave-shaped cross section are disposed in the hollow portion of the soundproof door 9 (see FIG. 1 of Patent Document 2).
Japanese Patent Laid-Open No. 11-36514 JP 2002-89142 A

しかしながら、上記従来の技術には、下記に示すような諸課題がある。   However, the above conventional techniques have the following problems.

まず、特許文献１に係る波状の成形板９は、接着剤を介して板状物８に接合されるに当り、垂直状態、即ち図８に例示された状態に維持することが困難である場合が多い。なぜならば、成形板９は、一般に厚さが薄く、軽量であるため、横方向から風などの気流変動により倒れ易いからである。   First, when the wavy shaped plate 9 according to Patent Document 1 is joined to the plate-like object 8 via an adhesive, it is difficult to maintain the vertical shape, that is, the state illustrated in FIG. There are many. This is because the molded plate 9 is generally thin and lightweight, and therefore easily collapses due to airflow fluctuations such as wind from the lateral direction.

次に、図９に示すごとく、金型成形プレス７による波状の成形板９の製造は、一般に長尺物、即ち長手方向の長さが長いものに対しては不向きである。なぜならば、原料（素材）が前述のごとく、粉末状又はチップ状、或いは繊維状物の植物片を金型７０内に投入することが困難であり、少なくとも連続供給には多大の困難を伴う場合が多いからである。   Next, as shown in FIG. 9, the production of the corrugated forming plate 9 by the mold forming press 7 is generally unsuitable for long objects, that is, those having a long length in the longitudinal direction. This is because, as described above, it is difficult to feed the plant pieces in the form of powder, chips, or fibers into the mold 70 as described above, and at least there is a great difficulty in continuous supply. Because there are many.

そして、金型７０は、比較的高価で複雑形状を有し、その製作には多大の労力及び費用を伴う場合が多い。   The mold 70 is relatively expensive and has a complicated shape, and its manufacture often involves a great deal of labor and cost.

また、金型７０の中央部７１と端部又は周縁部７２との間では、温度差を生じ易く、局部的な加熱温度のバラツキによる製品不良を生じ易い問題点がある。しかも、バッチ式であり、連続生産が困難である。   Further, there is a problem that a temperature difference is likely to occur between the central portion 71 and the end portion or the peripheral portion 72 of the mold 70, and a product defect is likely to occur due to local variations in heating temperature. Moreover, it is a batch type, and continuous production is difficult.

一方、特許文献２に係る防音ドア９内の吸音材９１は、図１０に示すごとく、短形体８１の表裏面に板状体８２を張り合わせた箱状物８の中空部８０内において、吸音材９３と遮音シート９４とを接合して配設することには、相当の困難を伴う場合がある。なぜならば、箱状物８の中空部８０は、いわば閉じこめられた空間であり、たとえ接着剤（図示略）を介しても吸音材９３や遮音シート９４を接合することは不可能に近いからである。   On the other hand, as shown in FIG. 10, the sound absorbing material 91 in the soundproof door 9 according to Patent Document 2 is a sound absorbing material in the hollow portion 80 of the box-shaped object 8 in which the plate-like body 82 is bonded to the front and back surfaces of the short body 81. It may be accompanied by considerable difficulty to arrange | position and arrange | position 93 and the sound-insulation sheet | seat 94. FIG. This is because the hollow portion 80 of the box-like object 8 is a confined space, and it is almost impossible to join the sound absorbing material 93 and the sound insulating sheet 94 even through an adhesive (not shown). is there.

そこで、本発明は、前記問題点に鑑みてなされたものであり、本発明が解決しようとする課題は、反りや歪みを生じることがなく、比較的簡単な構造で、連続生産が可能なハニカムコアドア及びその製造方法を提供しようとするものである。   Therefore, the present invention has been made in view of the above problems, and the problem to be solved by the present invention is a honeycomb capable of continuous production with a relatively simple structure without causing warpage or distortion.

本発明の実施の形態について、実施例１及び実施例２、更には、請求項１〜請求項８に記載の発明と対応させながら、図面を参照して、本発明の各種の実施の態様をも具体的に説明する。   With respect to the embodiments of the present invention, various embodiments of the present invention will be described with reference to the drawings while corresponding to the first and second embodiments and further the first to eighth aspects of the present invention. Will also be described in detail.

まず、本発明に係るハニカムコアドア４は、図７に示すごとく、縦桟４２と横桟４３と中央桟４４とを有するフラッシュドアであって、このフラッシュドアの中空部４０には、補強桟４１の側面部において接合材３を介在して加熱成形素材からなる屈折板状変形体１が蜂の巣状に配設されて構成されている（請求項１、図３、図６参照）。   First, as shown in FIG. 7, the honeycomb core door 4 according to the present invention is a flash door having a vertical beam 42, a horizontal beam 43, and a central beam 44. The hollow portion 40 of the flash door includes a reinforcing beam. A refracting plate-like deformed body 1 made of a thermoforming material is disposed in a side surface portion 41 in a honeycomb shape with a bonding material 3 interposed therebetween (see claims 1, 3, and 6).

ここで、図７はハニカムコアドア４の切開正面図、図３及び図６は屈折板状変形体１を蜂の巣状に接合材３を介在して、補強桟４１に対して装着する状態を示す正面図である。なお、ここで注目すべきことは、屈折板状変形体１は加熱ロールによって略湾曲波形状に屈曲成形されていることである。これにより、比較的簡単な構造で反りや歪みを生じることがないハニカムコアドア４を桟取付け工程及びドア内組み込み工程などの手段を通じて、容易に構成することが出来ることである。   Here, FIG. 7 is an incision front view of the honeycomb core door 4, and FIGS. 3 and 6 show a state in which the refracting plate-like deformed body 1 is attached to the reinforcing bar 41 with the bonding material 3 interposed in a honeycomb shape. It is a front view. It should be noted that the refracting plate-like deformation body 1 is bent and formed into a substantially curved wave shape by a heating roll. Thus, the honeycomb core door 4 that has a relatively simple structure and does not warp or be distorted can be easily configured through means such as a crosspiece attaching step and a door-incorporating step.

ハニカムコアドア４の「ハニカム」とは、原義は、「蜂の巣」の構造体の名称のことであり、また「コア」とは「芯材」のことである。それ故、ハニカムコアドア４は、略湾曲波形状の屈折板状変形体１を蜂の巣状に配設したドアのことである。ハニカム構造体は、一般にはコルゲートコアともいい、略湾曲波形状の木材、クラフト紙、アルミニウ合金、ステンレス鋼、ガラス繊維強プラスチック材などが用いられている。   The “honeycomb” of the honeycomb core door 4 originally means the name of the structure of “honeycomb”, and the “core” means “core material”. Therefore, the honeycomb core door 4 is a door in which the refracting plate-like deformed body 1 having a substantially curved wave shape is arranged in a honeycomb shape. The honeycomb structure is generally referred to as a corrugated core, and substantially curved wave-shaped wood, kraft paper, aluminum alloy, stainless steel, glass fiber strong plastic material, or the like is used.

この点、本発明に係るハニカムコアドア４は、加熱成形素材１０（図１、図５参照）は、熱可塑性樹脂板状成形体、繊維強化熱可塑性樹脂板状成形体、不織布板状成形体、竹材板状加工体、厚紙・ダンボール板状体のいずれか１種又はい１種以上から構成される（請求項２〜請求項７参照）。
なお、上記厚紙・ダンボール板状体は、単なるクラフト紙からなるハニカム構造のダンボール紙に止まらず、これらの表裏面において、前記熱可塑性樹脂板状成形体を被覆したもの又は繊維強化熱可塑性樹脂板状成形体及び不織布板状成形体とのサンドイッチ構造のものを含むことを特徴としている。 In this respect, the honeycomb core door 4 according to the present invention includes a thermoforming material 10 (see FIGS. 1 and 5), a thermoplastic resin plate-shaped molded body, a fiber-reinforced thermoplastic resin plate-shaped molded body, and a nonwoven fabric plate-shaped molded body. It is comprised from any 1 type, or 1 type or more of a bamboo board processed body and a cardboard cardboard board (refer Claim 2-7).
The cardboard / cardboard plate-like body is not limited to a honeycomb-structured corrugated cardboard made of craft paper, and the front and back surfaces of the cardboard-coated body are coated with the thermoplastic resin plate-shaped body or fiber-reinforced thermoplastic resin plate. It is characterized by including the thing of the sandwich structure with a shape molded object and a nonwoven fabric plate-shaped molded object.

また、略湾曲波形状の加熱成形素材からなる屈折板状変形体１を得るに当たっては、図１及び図５に示すごとく、蜂の巣状を経て、更には整形又は切断及び成形物調整工程を経て形成される。なお、蜂の巣状は、例えば図２にすごとく、断面形状が中央部において凹凸部（２０１、２０２）を有する加熱ロール２１、２２、２３、２４が用いられる。   Further, in order to obtain the refracting plate-like deformed body 1 made of a substantially curved wave-shaped thermoformed material, as shown in FIGS. 1 and 5, it is formed through a honeycomb shape and further through shaping or cutting and a molded article adjusting step. Is done. For example, as shown in FIG. 2, heating rolls 21, 22, 23, and 24 having a concavo-convex portion (201 and 202) at the center are used for the honeycomb shape.

これにより、図２の最下段に示すごとく、中央部において、凹凸曲面（１０１、１０２）を有する略湾曲波形状の屈折板状変形体１を得ることが出来る。したがって、図３及び図６に示すごとく、補強桟４１の側面部に接合材３を介在して、屈折板状変形体１を装着固定することが容易となる。   As a result, as shown in the lowermost stage of FIG. 2, a substantially curved wave-shaped refracting plate-like deformable body 1 having an uneven curved surface (101, 102) can be obtained at the center. Therefore, as shown in FIGS. 3 and 6, it is easy to attach and fix the refractive plate-shaped deformable body 1 with the bonding material 3 interposed between the side surfaces of the reinforcing bar 41.

なぜならば、屈折板状変形体１が図２最下段に示すごとく、中央部において、凹部１０２を有する屈折板状変形体１にあっては、接合材３、例えばスクリューネジやステーブルが打設し易く、屈折板状変形体１を補強桟４１の側面部において、迅速容易に取付け固定することが出来るからである。   This is because, as shown in the lowermost part of FIG. 2, the refractive plate-like deformable body 1 having the concave portion 102 is provided with a bonding material 3 such as a screw screw or a stable. This is because the refractive plate-like deformable body 1 can be quickly and easily attached and fixed on the side surface of the reinforcing bar 41.

次に、図３及び図６に示すごとく、上記屈折板状変形体１は側面形態（形状）が連続的な台形又は湾曲凸形状を有する。そのため、図７に示すごとく、屈折板状変形体１を補強桟４１の側面部に取付け固定すると、全体形状としては「蜂の巣状」のハニカム構造体を形成することが出来る。   Next, as shown in FIGS. 3 and 6, the refracting plate-like deformable body 1 has a trapezoidal shape or a curved convex shape in which the side surface shape (shape) is continuous. Therefore, as shown in FIG. 7, when the refracting plate-like deformable body 1 is attached and fixed to the side surface portion of the reinforcing bar 41, a honeycomb structure having a “honeycomb shape” as an overall shape can be formed.

なお、図７は、前述のごとく、ハニカムコアドア４の切開正面図を示すものであるが、図面を簡略化するため、「蜂の巣状」のハニカム構造体は、その一部のみか例示してある。   FIG. 7 shows a cutaway front view of the honeycomb core door 4 as described above. However, in order to simplify the drawing, only a part of the “honeycomb-like” honeycomb structure is illustrated. is there.

したがって、本発明に係るハニカムコアドア４は、本来、従来よりよく知られた「蜂の巣状」のハニカム構造体のごとく、フラッシュドアの中空部４０には従横に多数の補強桟４１が配設されているものである。これに伴い「蜂の巣状」のハニカム構造も多数形成され、屈折板状変形体１も従横に多数形成されたものである。   Accordingly, the honeycomb core door 4 according to the present invention is originally provided with a number of reinforcing bars 41 in the hollow portion 40 of the flash door, like a “honeycomb-like” honeycomb structure, which has been well known conventionally. It is what has been. Along with this, a large number of “honeycomb-like” honeycomb structures are formed, and a large number of refractive plate-like deformation bodies 1 are also formed sideways.

次に、本発明に係るハニカムコアドア４の製造方法について説明する。図４及び請求項８においてフラッシュドアされているごとく、熱可塑性樹脂板状成形体、熱可塑性樹脂板状成形体繊維強化、不織布板状成形体、竹材板状加工体、厚紙・ダンボール板状体の形成工程と、加熱成形素材を風乾又は水蒸気下で加熱ロール２を介在して屈曲成形する加熱ロール成形工程と、屈曲成形された成形物（屈折板状変形体の１のこと）を整形又は切断する成形物調整工程と、縦桟４２と横桟４３と中央桟４４を凹凸嵌合接続する桟取付け工程と、補強桟４１に接合材を介在した屈折板状変形体１をフラッシュドアの中空部の内部に蜂の巣状に配設するドア内組み込み工程とからなるハニカムコアドア４の製造方法である。   Next, a method for manufacturing the honeycomb core door 4 according to the present invention will be described. As shown in FIGS. 4 and 8, a thermoplastic resin plate-shaped molded body, a thermoplastic resin plate-shaped molded body, fiber reinforcement, a nonwoven fabric plate-shaped molded body, a bamboo plate-shaped processed body, and a cardboard / cardboard plate-shaped body. Forming a thermoforming material, bending a thermoforming material by air-drying or steaming with a heating roll 2 interposed, and shaping or bending the molded product (refractive plate-like deformed body 1). The step of adjusting the molded product to be cut, the step of attaching the concave and convex portions of the vertical beam 42, the horizontal beam 43, and the central beam 44, and the refracting plate-like deformed body 1 with the bonding material interposed in the reinforcing beam 41 are hollow in the flash door. It is a manufacturing method of the honeycomb core door 4 which consists of the process in the door arrange | positioned inside a part in a honeycomb form.

ここで図４は、ハニカムコアドア４の製造フローシートを示す説明図であり、上記ハニカムコアドア４の製造方法と対応する物である。   Here, FIG. 4 is an explanatory view showing a manufacturing flow sheet of the honeycomb core door 4, and corresponds to the manufacturing method of the honeycomb core door 4.

まず、注目すべきことは、屈折板状変形体１は、図１、図２、図５に示すごとく、加熱成形素材１０を中央部において、凹部２０２及び凸部２０１を有する加熱成形素材２を使用することである。これにより、図２の最下段に示すごとく、中央部において、凹部１０２及び凸部１０１を有する屈折板状変形体１を得ることが出来る。   First, it should be noted that the refracting plate-like deformable body 1 has a thermoforming material 2 having a concave portion 202 and a convex portion 201 at the center portion as shown in FIGS. Is to use. Thereby, as shown in the lowermost stage of FIG. 2, it is possible to obtain the refracting plate-like deformed body 1 having the concave portion 102 and the convex portion 101 in the central portion.

したがって、図３及び図６に示すごとく、補強桟４１の側面部に対して、上記屈折板状変形体１を接合材３を介在して、取付け固定するに当たっては、迅速容易に屈折板状変形体１を補強桟４１の側面部に取付け装着することが出来る。これにより、図７に示すごとく、フラッシュドアの中空部４０において、蜂の巣状のハニカム構造体を有するハニカムコアドア４を迅速容易に得ることが出来る。   Therefore, as shown in FIGS. 3 and 6, when the above-mentioned refracting plate-like deformed body 1 is attached and fixed to the side surface portion of the reinforcing bar 41 with the bonding material 3 interposed, the refracting plate-like deformed shape can be quickly and easily fixed. The body 1 can be attached and attached to the side surface of the reinforcing bar 41. Thereby, as shown in FIG. 7, in the hollow portion 40 of the flash door, the honeycomb core door 4 having a honeycomb-like honeycomb structure can be obtained quickly and easily.

なぜならば、ハニカム構造体は、圧縮強度が大きく、断熱効果をも有するため、フラッシュドア内における空気中の水分や熱の移動を抑制することが出来る。   This is because the honeycomb structure has a high compressive strength and also has a heat insulating effect, so that movement of moisture and heat in the air in the flash door can be suppressed.

したがって、ハニカムコアドア４において反りや歪みの発生が少なく、比較的簡単な構造でもって、軽量で、吸音効果、遮音効果にも優れたハニカムコアドア４を容易に得ることが出来る。   Therefore, the honeycomb core door 4 is less likely to be warped or distorted, has a relatively simple structure, is lightweight, and can easily obtain the honeycomb core door 4 that is excellent in sound absorption effect and sound insulation effect.

ハニカム構造体は、あたかも多数の独立孔を有する「穴明き板」のような形状を有するため、上記のごとく、吸音効果、遮音効果が優れると共に、軽量で断熱効果をも有することになる。   Since the honeycomb structure has a shape like a “perforated plate” having a large number of independent holes, as described above, the honeycomb structure is excellent in sound absorption effect and sound insulation effect, and is lightweight and has a heat insulation effect.

また、屈折板状変形体１は、熱可塑性樹脂板状成形体、繊維強化熱可塑性樹脂板状成形体、不織布板状成形体、熱可塑性樹脂板状成形体を被覆した厚紙・ダンボール板状体によりなるため、１２０℃〜４００℃位の温度で、水蒸気雰囲気下、又は水漬膨潤の状態において、加熱ロール２を介在して屈曲成形される。   Further, the refractive plate-like deformable body 1 is a cardboard / cardboard plate-like body coated with a thermoplastic resin plate-like shaped body, a fiber reinforced thermoplastic resin plate-like shaped body, a nonwoven fabric plate-like shaped body, or a thermoplastic resin plate-like shaped body. Therefore, it is bent and formed at a temperature of about 120 ° C. to 400 ° C. in a water vapor atmosphere or in a submerged swelling state with the heating roll 2 interposed.

一方、竹材板状加工体は、加熱ロール２によって容易に曲げ加工することが出来ると共に、柔軟性を有するものである。   On the other hand, the bamboo plate-like processed body can be easily bent by the heating roll 2 and has flexibility.

そのため、上記のごとく、屈折板状変形体１が熱可塑性樹脂板状成形体、繊維強化熱可塑性樹脂板状成形体、不織布板状成形体、熱可塑性樹脂板状成形体が両面に被覆された厚紙・ダンボール板状体などに、勝るとも劣らぬ加熱成形素材１０の一つである。しかも、現在では未利用に近い天然資材として、竹材板状加工体の積極的利用は好ましいものである。   Therefore, as described above, the refractive plate-shaped deformable body 1 is coated on both sides with a thermoplastic resin plate-shaped molded body, a fiber-reinforced thermoplastic resin plate-shaped molded body, a nonwoven fabric plate-shaped molded body, and a thermoplastic resin plate-shaped molded body. It is one of the thermoforming materials 10 that is not inferior to cardboard and corrugated cardboard. In addition, as a natural material that is almost unused at present, active use of a bamboo plate-like processed body is preferable.

以上の説明のごとく、本発明に係るハニカムコアドア４は、反りや歪みを生じることが少なく、断熱性、吸音性、遮音性に優れると共に、比較的簡単な構造で軽量なフラッシュドアから構成される。しかもハニカムコアドア４は、加熱ロール成形工程、整形又は切断、成形物調整工程などの諸手段により、比較的迅速容易に形成出来る。   As described above, the honeycomb core door 4 according to the present invention is formed of a lightweight flash door that is less likely to be warped or distorted, has excellent heat insulation properties, sound absorption properties, and sound insulation properties, and has a relatively simple structure. The Moreover, the honeycomb core door 4 can be formed relatively quickly and easily by various means such as a heating roll forming process, shaping or cutting, and a molded article adjusting process.

また、縦桟４２、横桟４３、中央桟４４は、蟻掛け凹凸嵌合や鎌掛け凹凸嵌合の採用により、強固で強靱やなハニカム構造のフラッシュドアからなるハニカムコアドア４を、比較的簡単な手段である凹凸嵌合接続、桟取付け工程、ドア内組み込み工程などの連続生産にも適した製造方法によりハニカムコアドア４を容易に得ることが出来る。   Further, the vertical crosspiece 42, the horizontal crosspiece 43, and the central crosspiece 44 are provided with a honeycomb core door 4 made of a flash door having a strong and tough honeycomb structure by adopting a dovetail concave and convex fitting or sickle hanging concave and convex fitting. The honeycomb core door 4 can be easily obtained by a manufacturing method suitable for continuous production such as uneven fitting connection, crosspiece attachment process, and door incorporation process, which are simple means.

これは屈折板状変形体１が熱可塑性樹脂板状成形体、繊維強化熱可塑性樹脂板状成形体、不織布板状成形体などの加熱すると容易に塑性変形を起こし、冷却すると可塑的に硬化する加熱成形素材１０からなる屈折板状変形体１の性質を巧みに利用することによって、特許文献１や特許文献２に開示されたごときハニカム構造体よりも迅速容易に屈曲成形することが可能な屈折板状変形体１の蜂の巣状コアを有するハニカムコアドア４を得ることが出来るのである。   This is because the refractive plate-shaped deformable body 1 easily undergoes plastic deformation when heated, such as a thermoplastic resin plate-shaped molded body, a fiber reinforced thermoplastic resin plate-shaped molded body, and a nonwoven fabric plate-shaped molded body, and when cooled, it is plastically cured. By utilizing the properties of the refractive plate-like deformable body 1 made of the thermoforming material 10, the refraction that can be bent and formed more quickly and easily than the honeycomb structure as disclosed in Patent Document 1 or Patent Document 2. The honeycomb core door 4 having the honeycomb core of the plate-like deformable body 1 can be obtained.

以下、本発明において好ましい実施例１及び実施例２について、図面を用いて具体的に説明する。   Hereinafter, preferred embodiments 1 and 2 of the present invention will be specifically described with reference to the drawings.

本発明に係るハニカムコアドア４は、図１〜図４に示すごとく、下記に示すような製造方法によって、比較的容易な手段によって得られるものである。   As shown in FIGS. 1 to 4, the honeycomb core door 4 according to the present invention is obtained by a relatively easy means by a manufacturing method as described below.

まず、図１に示すごとく、加熱成形素材１０は引出し整形用の加熱ロール２１によって予備加熱され、一旦平滑に整形加工される。均一の厚さの加熱ロール１０を得るためである。   First, as shown in FIG. 1, the thermoforming material 10 is preheated by a heating roll 21 for drawing shaping and is once shaped smoothly. This is for obtaining the heating roll 10 having a uniform thickness.

次に、加熱ロール１０は送りロール２２、２３によって、屈曲成形用の加熱ロール２４、２５に搬送される。この加熱ロール２４、２５は、その一部が示されているが、全体としては、加熱ロール２５の次には、加熱ロール２４の水平位置に、更に屈曲成形用の加熱ロール（図示略）が配設されている。そして、強制冷却されて、図２及び図３に示すごとく、断面形状が湾曲状の凸部１０１及び凹部１０２を有すると共に、側面形状が略湾曲台形状の屈折板状変形体１が得られる。ここで最も注目すべきことは、加熱ロール１０が屈曲成形されると一時的に加熱ロール２４、２５は回転を停止し、その間に強制冷却により５０℃以下に屈折板状変形体１が冷却され、冷却された所定形状の成形物を加熱ロールの横方向にアームを介して押し出す。これにより、略湾曲台形状に屈曲成形された成形物が得られることである。   Next, the heating roll 10 is conveyed by the feed rolls 22 and 23 to the heating rolls 24 and 25 for bending. Although a part of the heating rolls 24 and 25 is shown, as a whole, a heating roll (not shown) for bending is further placed next to the heating roll 25 at a horizontal position of the heating roll 24. It is arranged. 2 and 3, the refractive plate-like deformed body 1 having the convex portions 101 and the concave portions 102 having a curved cross-sectional shape and having a substantially curved trapezoidal shape on the side surface is obtained. The most notable point here is that when the heating roll 10 is bent, the heating rolls 24 and 25 temporarily stop rotating, and during that time, the refractive plate-shaped deformable body 1 is cooled to 50 ° C. or less by forced cooling. Then, the cooled molded product having a predetermined shape is extruded through the arm in the lateral direction of the heating roll. As a result, a molded product bent into a substantially curved trapezoidal shape is obtained.

これは、熱可塑性樹脂が略１５０℃〜４００℃に加熱すると塑性変形し、略１００℃〜０℃近くまで急冷することにより、そのままの形状で硬化成形される性質を利用したものである。つまり、押出成形や射出成形においても利用されている原理を、加熱と冷却との間欠的なロール成形にも応用するものである。   This utilizes the property that the thermoplastic resin is plastically deformed when heated to approximately 150 ° C. to 400 ° C., and is rapidly molded to approximately 100 ° C. to 0 ° C. to be cured and molded as it is. That is, the principle utilized also in extrusion molding and injection molding is applied also to intermittent roll forming of heating and cooling.

上記加熱ロール２１〜２５は、いずれも回動回転軸２０を有し、特に加熱ロール２５は下方において、強制冷却用の０℃〜５℃位の強風吹出しノズル２６を有する。これにより、加熱成形素材１０は、５０℃以下まで急冷されて、側面形状が略湾曲台形状の屈曲成形体としての屈折板状変形体１（図２の最下段図及び図３の１０３、１０４参照）を得ることが出来る。   Each of the heating rolls 21 to 25 has a rotating rotary shaft 20, and in particular, the heating roll 25 has a strong wind blowing nozzle 26 of about 0 ° C. to 5 ° C. for forced cooling below. As a result, the thermoformed material 10 is rapidly cooled to 50 ° C. or lower, and the refractive plate-like deformed body 1 as a bent molded body having a substantially curved trapezoidal side surface (the lowermost diagram in FIG. 2 and 103 and 104 in FIG. 3). See).

そして、上記加熱ロール２４、２５は、図２の上段図及び中段図に示すごとく、断面形状が中央部において、凹部２０１及び凸部２０２を有する。なお、加熱ロール２４、２５は、両端部において平滑部２０３を有する。加熱ロール１０の加熱ロール成形時に生じた、いわゆる「耳」と称する余尺物の加圧成形及び「送り出し」又は「引き出し」のためである。   And the said heating rolls 24 and 25 have the recessed part 201 and the convex part 202 in cross-sectional shape in the center part, as shown to the upper stage figure and middle stage figure of FIG. In addition, the heating rolls 24 and 25 have the smooth part 203 in both ends. This is for pressure forming and “feeding out” or “drawing” of an extra item, which is called “ear”, which occurred during the heating roll forming of the heating roll 10.

このようにして、断面形状が、図２の下段図に示すごとく、凹部１０２及び凸部を有する湾曲状の屈曲成形体としての屈折板状変形体１を得ることが出来る。また、側面形状は、図３に示すごとく、連続した略台形状の屈折板状変形体１を呈し、全体として略湾曲波形状の屈曲成形物の形状を有する。   In this way, as shown in the lower diagram of FIG. 2, the refractive plate-like deformable body 1 as a curved bent molded body having the concave portion 102 and the convex portion can be obtained. Further, as shown in FIG. 3, the side surface shape has a continuous substantially trapezoidal refracting plate-like deformed body 1, and has the shape of a bent product having a generally curved wave shape as a whole.

次に、上記略湾曲波形状の屈曲成形物としての屈折板状変形体１は、補強桟４１の側面部において、ボトル３１とナット３２の接合材３によって間欠的に接続固定される。なお、接合材３は、ボルト３１やナット３２に代えて、各種形状のタッピングネジ６やステープル６１に代えることが出来る（図６参照）。なお、上記補強桟の側面部には、屈折板状変形体１が当接する部分に位置安定用の凹部を形成することが好ましい。   Next, the refracting plate-like deformed body 1 as a bent product having a substantially curved wave shape is intermittently connected and fixed at the side surface portion of the reinforcing bar 41 by the bonding material 3 of the bottle 31 and the nut 32. Note that the bonding material 3 can be replaced with tapping screws 6 or staples 61 of various shapes instead of the bolts 31 and the nuts 32 (see FIG. 6). In addition, it is preferable that a concave portion for position stabilization is formed on a side portion of the reinforcing bar at a portion where the refracting plate-like deformable body 1 abuts.

そして、前記屈折板状変形体１は、請求項３〜請求項５に例示の各種の加熱ロール１０により構成する。また、補強桟４１は、縦桟４２、横桟４３、中央桟４４と共に、各種木材、例えば針葉樹木材、広葉樹木材、集成材、ランバー特殊合板などにより構成する。また、前記屈折板状変形体１は、全体形状として略湾曲波形状の屈曲成形物である。   And the said refractive plate-shaped deformation body 1 is comprised by the various heating roll 10 illustrated in Claims 3-5. The reinforcing bar 41 is made of various kinds of wood such as coniferous wood, hardwood wood, laminated lumber, lumbar special plywood, and the like, together with the vertical rail 42, the horizontal rail 43, and the central rail 44. The refracting plate-like deformable body 1 is a bent product having a substantially curved wave shape as a whole.

また、屈折板状変形体１は、全体形状として、蜂の巣状に接合材３を介在して補強桟４１の側面部に取付け固着される。このようにして、略湾曲波形状の屈曲成形物としての屈折板状変形体１は、補強桟４１の側面部に接合材３を介在して、全体形状として蜂の巣状に配設され、フラッシュドアの中空部４０内において、ハニカム構造体を形成する。   Further, the refracting plate-like deformable body 1 is attached and fixed to the side surface portion of the reinforcing bar 41 with the bonding material 3 interposed in a honeycomb shape as an overall shape. In this way, the refracting plate-like deformed body 1 as a bent product having a substantially curved wave shape is disposed in a honeycomb shape as a whole shape with the bonding material 3 interposed on the side surface portion of the reinforcing bar 41, and a flash door. A honeycomb structure is formed in the hollow portion 40.

その結果、フラッシュドアとしてのハニカムコアドア４を製造することが出来る（図７参照）。ハニカムコアドア４の製造方法は、図４に示すごとく、（１）加熱成形素材１０の形成工程である「原料調整工程」と、この加熱成形素材１０を全体形状として略湾曲波形状に屈曲成形された屈折板状変形体１を得る（２）「加熱ロール成形工程」と、（３）屈曲成形を所定の長さや形状に整形又は切断する「成形物調整工程」と、図３に示すごとき「桟取付け工程」と、ハニカムコアドア４の最終工程である「ドア内組み込み工程」（図７参照）とよりなる。   As a result, the honeycomb core door 4 as a flash door can be manufactured (see FIG. 7). As shown in FIG. 4, the manufacturing method of the honeycomb core door 4 is as follows: (1) “Raw material adjustment process” that is a process of forming the thermoforming material 10 and bending the thermoforming material 10 as a whole into a substantially curved wave shape. (2) “heating roll forming step”, (3) “molded product adjusting step” for shaping or cutting the bent forming into a predetermined length or shape, and as shown in FIG. It consists of a “crosspiece attaching step” and a “door-incorporating step” (see FIG. 7), which is the final step of the honeycomb core door 4.

これにより、反りや歪みを生じることが少なく、比較的簡単な構造で連続生産が可能なハニカムコアドア４及びその製造方法を提供することが出来る。   As a result, it is possible to provide a honeycomb core door 4 that is less likely to be warped or distorted and can be continuously produced with a relatively simple structure, and a method for manufacturing the same.

また、本例によれば、軽量なフラッシュドアとしての比較的簡単な構造で、圧縮強度、吸音性、遮音性、断熱性に優れたハニカムコアドア４（図７参照）を迅速容易に得ることが出来る。そして、加熱成形素材１０として竹材板状加工体を使用する態様においては、断面形状が凹凸湾曲物（図２の最下段参照）を容易に得ることが出来る。   Moreover, according to this example, the honeycomb core door 4 (see FIG. 7) having a relatively simple structure as a lightweight flash door and excellent in compressive strength, sound absorption, sound insulation, and heat insulation can be obtained quickly and easily. I can do it. And in the aspect which uses a bamboo board-shaped processed object as the thermoforming raw material 10, a cross-sectional shape can obtain an uneven | corrugated curved object (refer the lowest step of FIG. 2) easily.

「もうそうちく」や「しばちく」のごとく、直径が比較的大きな竹材を４〜５等分に分割すれば、図３の最下段図に示すごとく、凹部１０２及び凸部１０１を有する断面形状が湾曲形状の屈折板状変形体１を得ることが容易だからである。   If a bamboo material having a relatively large diameter is divided into 4 to 5 equal parts, as in “Motosokuchi” and “Shibachiku”, a cross section having a concave portion 102 and a convex portion 101 as shown in the bottom stage diagram of FIG. This is because it is easy to obtain the refracting plate-like deformed body 1 having a curved shape.

本例は、図５〜図７に示すごとく、側面形状が実施例１における略湾曲台形状の屈折板状変形体１に代えて、連続エス字状の略湾曲波形状を呈する屈折板状変形体１からなるハニカムコアドア４及びその製造方法を提供するものである。   In this example, as shown in FIG. 5 to FIG. 7, the side surface shape replaces the substantially curved trapezoidal refracting plate-like deformation body 1 in the first embodiment, and the refracting plate-like deformation presents a substantially curved wave shape having a continuous s-shape. A honeycomb core door 4 made of a body 1 and a method for manufacturing the same are provided.

屈折板状変形体１は、図５に示すごとく、トンネル長方体形状の加熱ロール室５を用いて屈曲成形するものである。加熱ロール室５内には、多数の連続生産用の加熱ロール５１を有する。この加熱ロール５１は、中央部に回動回転軸５０を有し、前半は水蒸気雰囲気下であり、後半はエアーカーテン５２を境界として強制冷却用の強風雰囲気下にある。   As shown in FIG. 5, the refracting plate-like deformed body 1 is formed by bending using a heating roll chamber 5 having a tunnel rectangular shape. The heating roll chamber 5 has a number of heating rolls 51 for continuous production. The heating roll 51 has a rotating shaft 50 at the center, the first half is in a steam atmosphere, and the second half is in a strong wind atmosphere for forced cooling with the air curtain 52 as a boundary.

そして、屈折板状変形体１は、図６に示すごとく、補強桟４１の側面部において、接合材６としてのタッピングネジ６２及び又はコ字状のステープル６２を介在して、取付け固定される。そして、このように構成された屈折板状変形体１は、図７に示すごとく、桟取付け工程及びドア内組み込み工程において、縦桟４２と横桟４３と中央桟４４とを少なくとも有するフラッシュドアの中空部４０内において、ハニカム構造体として、蜂の巣状に配設される。その他の構成は、実施例１と同様にした。 Then, as shown in FIG. 6, the refractive plate-like deformable body 1 is attached and fixed on the side surface portion of the reinforcing bar 41 with a tapping screw 62 and / or a U-shaped staple 62 as the bonding material 6 interposed. Then, as shown in FIG. 7, the refracting plate-shaped deformable body 1 configured as described above is a flash door having at least a vertical beam 42, a horizontal beam 43, and a central beam 44 in the beam mounting process and the door mounting process. In the hollow portion 40, the honeycomb structure is disposed in a honeycomb shape. Other configurations were the same as those in Example 1.

これにより、図７に示すごとく、連続した略湾曲波形状の屈折板状変形体１が従横に多数配設されたハニカムコアドア４を得ることが出来る。このハニカムコアドア４は、実施例１により得られたフラッシュドアと同様に軽量で比較的簡単な構造でありながら、圧縮強度、吸音性、遮音性、断面性などに優れた反りや歪みを生じることが少ないハニカムコアドア４を比較的迅速容易に得ることが出来る。   As a result, as shown in FIG. 7, a honeycomb core door 4 in which a large number of continuous substantially curved wave-shaped refracting plate-like deformed bodies 1 are disposed laterally can be obtained. The honeycomb core door 4 has a light and relatively simple structure similar to the flash door obtained in the first embodiment, but generates warpage and distortion excellent in compressive strength, sound absorption, sound insulation, and cross-section. The honeycomb core door 4 with a small amount can be obtained relatively quickly and easily.

したがって、本例によれば、竹材板状加工体や熱可塑性樹を両面被覆した厚紙・ダンボール板状体などのごとく、比較的に多くの独立気泡を有する多孔体からなる水分（湿分）の吸収能を有する加熱成形素材１０を使用することにより、水蒸気雰囲気下で水漬膨潤状態の加熱成形素材１０を連続生産が可能である。そして、比較的簡単な構造によるハニカム構造体としてのハニカムコアドア４を、比較的迅速容易に得ることが出来る。   Therefore, according to this example, moisture (moisture) composed of a porous body having a relatively large number of closed cells, such as a bamboo board-like processed body or a cardboard / cardboard board-like body coated on both sides of a thermoplastic tree. By using the thermoformed material 10 having an absorption capacity, it is possible to continuously produce the thermoformed material 10 in a swollen and swollen state under a steam atmosphere. And the honeycomb core door 4 as a honeycomb structure by a comparatively simple structure can be obtained comparatively quickly and easily.
