Description
【考案の詳細な説明】 本考案はと石膏ボードの改良を目的とする。[Detailed explanation of the idea] The purpose of this invention is to improve plasterboard.
石膏ボードは、価格が他の材料に比べて安く、
施工も比較的容易であるために、建築用不地材と
して広く利用されているが、石膏の性質から曲げ
強度や衝撃強度に弱く、通路や階段、子供部屋の
壁には使用出来ず、又比重が高く、結露しやすい
ので、室内結露などにより表面に貼つた化粧紙が
剥れたり、化粧紙貼り替え時に表面厚紙も一緒に
剥れてしまつて石膏ボード自体を張り替えねばな
らない等の欠点を有していた。 Gypsum board is cheaper than other materials,
Because it is relatively easy to construct, it is widely used as a building material, but due to the nature of plaster, it has low bending strength and impact strength, so it cannot be used for walls in hallways, stairs, and children's rooms. It has a high specific gravity and is prone to condensation, so it has disadvantages such as the decorative paper attached to the surface peeling off due to indoor condensation, and when replacing the decorative paper, the cardboard on the surface also peels off and the plasterboard itself has to be replaced. had.
本考案はこれ等の欠点を全て解決し、優れた建
築用板材を提供するものである。以下実施例に基
づいて詳述する。 The present invention solves all of these drawbacks and provides an excellent construction board. A detailed explanation will be given below based on examples.

５〜50m／ｍ程度、穴は円形でなくてもよいが円
形が応力を分散して好ましい。 The core layer 1 of gypsum is commonly used, and may be strengthened by incorporating fibrous materials as necessary. The front and back cardboards 2, 2 are mainly made of waste paper, and must have water absorption of a certain amount or more, and if necessary, the water resistance can be improved with resin or the like. As shown in Figure 2, the holes 4 that stop midway through the thickness of the plaster core layer 1 of the cardboard-gypsum board made by pasting cardboard 2 and 2 together on the front and back sides have a diameter of 3 to 15 m/m, and the holes are spaced from each other. The diameter of the hole is approximately 5 to 50 m/m. Although the hole does not have to be circular, it is preferable that the hole is circular in order to disperse stress.
天然木薄板３は、接着剤で前記厚紙上に接着さ
れており、広葉樹単板、針葉樹単板のいずれでも
良く、ロータリーカツト、スライスカツトのどち
らを用いてもよい。接着剤は熱硬化型、常温硬化
型のいずれでもよいが、硬化後収縮量の少ないも
のが好ましい。 The thin natural wood board 3 is bonded onto the cardboard with an adhesive, and may be either a hardwood veneer or a softwood veneer, and may be cut by rotary cut or slice cut. The adhesive may be either a thermosetting type or a room temperature curing type, but it is preferable to use one with a small amount of shrinkage after curing.
収縮量が大きいと接着後板が反つたり、ねじれ

てから行なうのが好ましい。接着剤はスプレツダ
ーにより石膏板の両面に塗布する。このようにす
ると接着剤中の水分が厚紙−石膏板内に浸透し、
熱圧締後反りやねじれが生じない。 This is because if the amount of shrinkage is large, the board is likely to warp or twist after bonding. If you use a thermosetting water-based adhesive, use a hot press to bond. Urea resin adhesives are commonly used, but it is necessary to add an extender or the like to reduce the shrinkage force. It is preferable that the hot pressing is carried out at 5 to 10 kg/cm 2 and 80 to 110° C., and after the natural wood thin plates 3 have been adhered and deposited for at least 30 minutes before the hot pressing. Adhesive is applied to both sides of the plasterboard using a spreader. In this way, the moisture in the adhesive will penetrate into the cardboard-gypsum board.
No warping or twisting occurs after hot pressing.
天然木薄板３の厚みは１枚で0.2〜3m／ｍの範
囲がよいが、1m／ｍ前後が経済的、性能的には
好ましい。0.2m／ｍ以下では強度面での向上が

く、かつ厚紙は石膏の芯層１と一体に張着されて
いるので、天然木薄板３の木口は厚紙−石膏板の
木口よりごくわづかに飛び出た形になる。 The thickness of each thin natural wood board 3 is preferably in the range of 0.2 to 3 m/m, but is preferably around 1 m/m from an economical and performance standpoint. This is because if it is less than 0.2 m/m, there is little improvement in strength, and if it is more than 3 m/m, the shrinkage force and twisting of the wood will be affected. After the construction board material of the present invention is integrated in this manner, it is cut into predetermined dimensions using a double sizer. At this time, the thin natural wood board 3 is strong and has a large restoring force, and the plaster is plastic and has no restoring power, and the cardboard is bonded together with the core layer 1 of the plaster, so the end of the thin natural wood board 3 is made of cardboard. -The shape slightly protrudes from the end of the plasterboard.

る。(Effects of the present invention) Sound insulation, gypsum board Since the cardboard-gypsum board has a hole 4 that stops halfway through the thickness of the gypsum core layer 1, the sound that passes through the thin natural wood board 3 is absorbed within the hole 4. At the same time, the sound is insulated by the plaster in the portion where the hole 4 does not penetrate through the cardboard-gypsum board.
すなわち、本考案の建築用材は遮音性と吸音性
を併する。 That is, the construction material of the present invention has both sound insulation and sound absorption properties.
防湿、放湿性

性を助長する。 Moisture-proofing and moisture-releasing properties Moisture that enters the holes 4 that stop midway through the thickness of the gypsum core layer 1 is absorbed by the gypsum core layer 1, and moisture-proofing properties are maintained. Moreover, the absorbed moisture is released into the atmosphere when it dries. Furthermore, natural wood thin board 3 and cardboard 2
It also has moisture absorbing and moisture-proofing properties, and promotes the moisture-proofing properties of the above-mentioned cardboard-gypsum board.

昭60−107331号参照）
このように天然木薄板の木口が飛び出すことに
より、第３図のようにつきつけ部の相互の密着が
確実にできる。 Ease of sticking Also, the above manufacturing method provides the following advantages. In other words, when the cardboard-gypsum board and the natural wood thin board 3 are heat pressed together and then cut with a double sizer, the cardboard-gypsum board is plastic and has no restoring force, whereas the natural wood thin board 3 has no elasticity. is strong and has a large restoring force, so the wood of the thin natural wood board 3 protrudes very slightly from the end of the cardboard-gypsum board. (Refer to Japanese Patent Application Laid-Open No. 60-107331.) By protruding the ends of the thin natural wood sheets in this way, it is possible to ensure that the butting parts are in close contact with each other as shown in FIG.
もし、厚紙−石膏板の木口が天然木薄板３の木
口より飛び出すと、天然木薄板３のつきつけ部は
密着できないことになる。 If the end of the cardboard-gypsum board protrudes from the end of the thin natural wood board 3, the abutting portion of the thin natural wood board 3 will not be able to make close contact.
