Description

【発明の詳細な説明】遮蔽板この発明は、特許請求の範囲の独立項の前提部分に規定された遮蔽板に関するものである。従来技術において、波形状及び平担状の紙製薄板を交互に重ね合わせたスラブ形状の遮蔽材は、フィンランド特許第３３，６７５号より知られている。このタイプの遮蔽材の問題は、垂直柱間において、これをどのようにして緊密に壁に接合させ得るか、ということである。他の問題は、波形状及び平担状の紙製薄板の間に残る空気路によって生起され、空気がこの路を流通し得て断熱性を低下させることである。本発明の目的は、断熱性、耐火性及び遮音性に優れていて、ある種の有機パルプ、特に、木製繊維パルプより製造される新規な遮蔽板を紹介することにある。本発明による遮蔽板は、請求項１の特徴部分に記載された新規な特徴により特徴づけられる。本発明の利点は、その遮蔽板が耐湿性があるとともに通気性があり、しかも優れた断熱性を有している。このタイプの遮蔽板は、上述のように当該板が木製繊維で形成されるので、木製建築物の断熱に用いるのに特に適している。本発明の他の利点は、遮蔽板がいくつかの多孔質の木製繊維材料層で形成され、この層は本来的に何等の接着剤を用いることなしに有利に接合される。もし、接着剤が用いられるなら、それには普通の商業的に手に入る木材用の接着剤が有利である。本発明のさらに、もう一つの利点は、木製繊維材料層が一緒に、それらの間に何等の開口空気孔を形成することなく均一な遮蔽板を形成することにある。本発明のさらにもう一つの利点は、遮蔽板が多孔質で可撓性があり、取り扱いが容易であることにある。たとえば、壁の垂直柱間の定寸遮蔽板として、迅速かつ緊密に設置することができる。本発明は、添付図面を参照しながら、以下により詳細に説明される。図１は、本発明による遮蔽板の斜視図である。図２は、図１の遮蔽板のＡ−Ａ断面を示す。図３は、図１の遮蔽板の他の適当なＡ−Ａ断面を示す。図４は、図１の遮蔽板の第３の適当なＡ−Ａ断面を示す。図５は、図１の遮蔽板の第４の適当なＡ−Ａ（部分）断面を示す。図６は、図５の遮蔽板のＢ−Ｂ断面を示す。遮蔽板１は、重ね合わされた多数の遮蔽板層２を含んでいる。遮蔽板層２は、ある種の多孔質有機パルプで形成され、難燃剤、腐食防止剤及び他の一般に有機性遮蔽材に使用されると同様の剤を添加することができる。前記の材料は、繊維長が１．０−５．０ｍｍ、最も有利には２．５−４．０ｍｍの範囲のハイバルクパルプと呼ばれる松の木より製造される加熱繊維化されたパルプであることが有利である。遮蔽板層２の厚さｅは、たとえば２−１５ｍｍである。遮蔽板層２において、繊維は均一に分散され、それぞれ異なる方向に不規則に配向されている。遮蔽板１は、たとえば、１０−５０枚の遮蔽板層２を重ね合わせて形成され、この場合、遮蔽板の厚さｋは例えば２５−１５０ｍｍとなる。遮蔽板１の幅１及び長さｐは、１＝５００−９００ｍｍ、ｐ＝１，０００−１，５００ｍｍ程度であるが、他の寸法とすることも可能である。遮蔽板１の断熱性能は、有利には０，０２５−０，０３５Ｗ／ｍＫ°程度である。遮蔽板１のかさ密度は、２５ｋｇ／ｍ³程度である。遮蔽板１の境界部３は、遮蔽板層２に対して垂直な面に配置された均一な遮蔽層４；５；６によって形成されており、この遮蔽層は、同一の有機パルプで形成される。遮蔽板１は、以下の要領で、有利に製造される。ハイバルクパルプ等の木製繊維パルプ中には、製造工程においてホウ砂等の適切な難燃剤と適切な腐食防止剤および白かび防止剤等がすでに混合されている。遮蔽板層２は、上記に述べたように、木製繊維パルプを数ミリメータの範囲内の厚さを持つ多孔質薄板に圧縮したものである。その後に、遮蔽板１は多数の遮蔽板層２を相互に重ね合わせ、薄板を一緒に圧縮し、それらを同時に所定の幅及び長さに切断することにより形成される。遮蔽板層の間には、予備の接着点７を例えば離間した点に設けることができ、ここには、層の把持を確実とするためのある種の接着剤、有利には木材用接着剤が塗布される（図５及び６）。遮蔽板１の境界部３は、含有されるリグニンの少なくとも一部を放出するように木製繊維パルプを分解させる水スプレーまたは水−接着剤スプレー（これは、水と木材用接着剤等の適当な無害の接着剤によって調製される水性接着剤混合物である）によって処理される。見方によっては、水の効果によって境界部３が溶解すると謂うこともできる。乾燥すると、湿潤した木製繊維パルプは均一な繊維パルプ層を形成すると同時に、遮蔽板層２を一緒に結合する。境界部３において、遮蔽板１の周囲には、均一な境界遮蔽層４が（図２）が遮蔽板１及び遮蔽板層２の面の横断方向に形成される。この変形例としては、重合する遮蔽板層２の端縁部において、遮蔽板片５，６が、境界遮蔽層として機能するべく、遮蔽板層に対して直角に、最も有利には適当な水ベースの無害な接着剤をもって接着されており、この遮蔽板片によって、遮蔽板層２は、均一な遮蔽板（図３及び４）として主に相互結合される。幅において、遮蔽板片５は、遮蔽板２（図３）の厚さに対応し、または遮蔽板片６は、遮蔽板１（図４）の厚さｋよりも広くなっている。後者の場合、遮蔽板片の端縁６ａ、６ｂは、折り返され、取り付けられ、例えば遮蔽板１の上面及び下面に接着される。Description: Shielding plate The present invention relates to a shielding plate as defined in the preamble of the independent claim. In the prior art, a slab-shaped shielding material in which corrugated and flat paper sheets are alternately stacked is known from Finnish Patent No. 33,675. The problem with this type of shield is how it can be tightly joined to the wall between the vertical columns. Another problem is that air passages remaining between the corrugated and flat paper sheets cause air to flow through the passages and reduce the insulation. SUMMARY OF THE INVENTION An object of the present invention is to introduce a novel shielding plate which is excellent in heat insulation, fire resistance and sound insulation and is made of a certain kind of organic pulp, especially wood fiber pulp. The shielding plate according to the invention is characterized by the novel features described in the characterizing part of claim 1. An advantage of the present invention is that the shielding plate has moisture resistance, air permeability, and excellent heat insulation. This type of shielding plate is particularly suitable for use in thermal insulation of wooden buildings, since the plate is formed of wooden fibers as described above. Another advantage of the present invention is that the shield is formed of several porous wood fiber material layers, which layers are advantageously joined together without the use of any inherent adhesive. If an adhesive is used, it is advantageous to use ordinary commercially available wood adhesives. Yet another advantage of the present invention is that the layers of wood fiber material together form a uniform shield without forming any open air holes between them. Yet another advantage of the present invention is that the shield is porous, flexible, and easy to handle. For example, it can be quickly and tightly installed as a fixed size shield between vertical columns of a wall. The present invention is described in more detail below with reference to the accompanying drawings. FIG. 1 is a perspective view of a shielding plate according to the present invention. FIG. 2 shows an AA cross section of the shielding plate of FIG. FIG. 3 shows another suitable AA section of the shielding plate of FIG. FIG. 4 shows a third suitable AA section of the shielding plate of FIG. FIG. 5 shows a fourth suitable AA (partial) cross section of the shielding plate of FIG. FIG. 6 shows a BB cross section of the shielding plate of FIG. The shielding plate 1 includes a number of overlapping shielding plate layers 2. The shield plate layer 2 is formed of some kind of porous organic pulp and may contain flame retardants, corrosion inhibitors and other agents commonly used in organic shields. Said material may be a heated fiberized pulp made from pine trees called high bulk pulp having a fiber length in the range of 1.0-5.0 mm, most preferably 2.5-4.0 mm. It is advantageous. The thickness e of the shielding plate layer 2 is, for example, 2 to 15 mm. In the shielding plate layer 2, the fibers are uniformly dispersed and are randomly oriented in different directions. The shielding plate 1 is formed by stacking, for example, 10 to 50 shielding plate layers 2, and in this case, the thickness k of the shielding plate is, for example, 25 to 150 mm. The width 1 and the length p of the shielding plate 1 are about 1 = 500-900 mm and p = about 1,000-1500 mm, but other dimensions are also possible. The heat insulation performance of the shielding plate 1 is advantageously about 0,025-0,035 W / mK °. The bulk density of the shielding plate 1 is about 25 kg / m ³ . The border 3 of the shielding plate 1 is formed by uniform shielding layers 4; 5; 6 arranged in a plane perpendicular to the shielding plate layer 2, this shielding layer being made of the same organic pulp. You. The shielding plate 1 is advantageously manufactured in the following manner. In a wooden fiber pulp such as a high bulk pulp, a suitable flame retardant such as borax and a suitable corrosion inhibitor and a mildew inhibitor are already mixed in a manufacturing process. As described above, the shielding plate layer 2 is obtained by compressing wooden fiber pulp into a porous thin plate having a thickness in the range of several millimeters. Thereafter, the shielding plate 1 is formed by laminating a number of shielding plate layers 2 on one another, compressing the sheets together and cutting them simultaneously to a predetermined width and length. Between the shield layers, a preliminary adhesive point 7 can be provided, for example, at a spaced-apart point, in which some adhesive, preferably wood adhesive, is used to ensure the gripping of the layer. Is applied (FIGS. 5 and 6). The border 3 of the shield 1 is provided by a water spray or a water-adhesive spray which breaks down the wood fiber pulp to release at least a part of the lignin contained therein, which may be a suitable spray such as water and wood glue. Which is an aqueous adhesive mixture prepared with harmless adhesives). Depending on the viewpoint, it can be said that the boundary portion 3 is dissolved by the effect of water. Upon drying, the wet wood fiber pulp forms a uniform fiber pulp layer while simultaneously bonding the shield layers 2 together. At the boundary 3, a uniform boundary shielding layer 4 (FIG. 2) is formed around the shielding plate 1 in a direction transverse to the surfaces of the shielding plate 1 and the shielding plate layer 2. As a variant of this, at the edge of the overlapping shielding plate layer 2, the shielding plate pieces 5, 6 are at right angles to the shielding plate layer, most advantageously suitable water, so as to function as a boundary shielding layer. Adhered with a harmless adhesive on the base, the shield pieces allow the shield layer 2 to be mainly interconnected as a uniform shield (FIGS. 3 and 4). In width, the shielding plate piece 5 corresponds to the thickness of the shielding plate 2 (FIG. 3), or the shielding plate piece 6 is wider than the thickness k of the shielding plate 1 (FIG. 4). In the latter case, the edges 6a, 6b of the shielding plate pieces are folded, attached, and adhered to, for example, the upper and lower surfaces of the shielding plate 1.
