本考案は溝加工予定部分のみ未加工予定部分よりも多層
で形成されて成る無機質板に関するものであり、その目
的とするところは鋸引き等の加工性を損うことなしに、
溝加工部分の強化を図ることの出来る無機質板に関する
ものである。[Detailed description of the invention] The present invention relates to an inorganic plate in which the portion to be grooved is formed with more layers than the portion not to be processed, and its purpose is to impair the workability of sawing, etc. Without,
This invention relates to an inorganic plate that can strengthen the grooved portion.
従来の無機質板は抄造された基板を数層積層したのち高
圧プレスで成形し、次いで数日乃至数週間養生して作ら
れており、全体が同一積層数で構成されていた。Conventional inorganic boards are made by laminating several layers of paper-made substrates, molding them using a high-pressure press, and then curing them for several days to several weeks, and the entire board is made up of the same number of layers.
その為に部分的に切削して溝を形成した場合には、溝部
分が他の部分に比較して極端に弱くなり、わずかの曲げ
や振動でもって溝部分が折れてしまい易い欠点を有して
いた。For this reason, when a groove is formed by partially cutting, the groove part becomes extremely weak compared to other parts, and the groove part has the disadvantage of being easily broken by slight bending or vibration. was.
この改善策として無機質板を高密度化する方法も汎く提
案されてはいたが、この場合においては、強度は向上し
、溝を形成しても容易には破損しなくなる反面、鋸引き
等の加工が困難となり使用しにくくなるという欠点を有
していた。As a method to improve this problem, a method of increasing the density of the inorganic plate has been widely proposed. It has the disadvantage that it is difficult to process and difficult to use.
本考案は上記従来の無機質板のかかる欠点を改善し、加
工性を損うことなしに且つ溝を形成した場合においても
容易には破損しにくい無機質板に関するものである。The present invention improves the drawbacks of the conventional inorganic plates mentioned above, and relates to an inorganic plate that does not impair workability and is not easily damaged even when grooves are formed.
以下、本考案を実施例の図面に基づいて詳細に説明する
。Hereinafter, the present invention will be described in detail based on drawings of embodiments.
本考案は第１図に示すように溝加工予定部分１のみ未加
工予定部分２よりも一層多く積層形成されて戊る無機質
板３であり、第２図は無機質板３に溝４を刻設形成した
ものである。As shown in Fig. 1, the present invention is an inorganic plate 3 in which the grooved portion 1 is laminated more than the unprocessed portion 2, and Fig. 2 shows the grooves 4 carved in the inorganic plate 3. It was formed.
本考案の無機質板３の製造方法を詳述すると、第３図に
示すようにミキー５内にアスベストの長繊維、グラスウ
ール、植物繊維、ポルトランド等を投入し、混合したの
ち、いったんチェスト６内に貯蔵し、次いで各抄造容器
７内に導入し、抄造容器７内を回転している丸網８でも
って抄造していく。To explain in detail the manufacturing method of the inorganic board 3 of the present invention, as shown in FIG. Then, they are introduced into each paper-making container 7, and paper-made using a circular screen 8 rotating inside the paper-making container 7.
丸網８で抄造された基板は、丸網８の上を通っている金
網コンベア９に順次転写されていく。The substrates formed using the circular mesh 8 are sequentially transferred onto a wire mesh conveyor 9 passing over the circular mesh 8.
丸網８から８３へ順次積層されながら金網コンベア９に
転写されていき、メーキングロール１０で所定の大きさ
に裁断され、高圧プレス工程、養生工程へと移動加工さ
れていく。The wire meshes 8 to 83 are sequentially stacked and transferred to the wire mesh conveyor 9, cut into a predetermined size by a making roll 10, and moved to a high-pressure pressing process and a curing process.
尚８乃至８２の丸網は第４図に示すような長胴形状であ
り、その巾寸法は所望の無機質板の巾寸法と略同−であ
るが８３の丸網は第５図に示すように複数個に分割され
ており、それぞれの小丸網８′の巾寸法及びその取り付
は位置は、得られた無機質板に刻設する溝の巾寸法、溝
の創設位置と略同−にしである。Note that the circular nets 8 to 82 have a long body shape as shown in FIG. 4, and their width is approximately the same as the width of the desired inorganic board, but the circular net 83 has a long body shape as shown in FIG. The width of each small round screen 8' and its mounting position are approximately the same as the width of the groove to be carved in the obtained inorganic board and the position of the groove. be.
第６図はプレス前の多数の抄造した基板１１を積層した
状態を示しており、第５図の基板１１′は部分的に突設
した状態になっているが、高圧プレスでもって圧縮形成
することにより平担な表面となる。Figure 6 shows a stacked state of a large number of paper-made substrates 11 before pressing, and although the substrate 11' in Figure 5 is partially protruding, it is compressed and formed using a high-pressure press. This results in a flat surface.
本考案の無機質板の用途としては、防火建材として建物
の内装用、外装用に使用するのが適しているが、その際
に無機質板の表面に塩化ビニール樹脂シート、印刷紙等
の化粧シートを貼着するとともにＶ形、Ｕ形、角形の溝
を形成すれば良い。The inorganic board of the present invention is suitable for use as a fireproof building material for the interior and exterior of buildings, but in this case, decorative sheets such as vinyl chloride resin sheets or printed paper may be applied to the surface of the inorganic board. What is necessary is to form a V-shaped, U-shaped, or rectangular groove at the same time as adhesion.
本考案の無機質板は上記の如く構成されており溝を刻設
形成する部分のみ高密度で出来ているので、溝を形成し
ても溝部分が破損し易くなるということはなくなり、又
鋸引き等の加工性も損なわれることはないという効果を
有している。The inorganic board of the present invention is constructed as described above, and only the part where the grooves are carved is made of high density, so even if the grooves are formed, the groove part will not be easily damaged, and the sawed part will not be easily damaged. This has the effect that the processability of the materials, etc., is not impaired.
