Abstract

<P>PROBLEM TO BE SOLVED: To provide a water resistant substrate material which is most suitable for constructing wall, floor or the like of water use section. <P>SOLUTION: An organic foamed board 14 having water resistance and non-water absorptiveness is joined to a water-resistant substrate board 15 for bonding a finished material with water-resistant adhesive 16. The organic foamed board 14 and the water-resistant substrate board 15 are joined and integrated with the water-resistant adhesive 16, so that a water resistant composite board has excellent heat insulating property and water resistance as a whole and total thickness is made large, so that bending rigidity of the water resistant composite body is made larger than that of a substrate board formed of a singular body. Although the total thickness is made large, the organic foamed board 14 is used and hence total weight of the water resistant composite board is not so remarkably increased as the one formed of a singular body. In addition, finished materials 13 such as tiles are adherent to a surface of the substrate board 15 and the total thickness is made large, so that the water resistant composite board can stand itself when installed. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

本発明は、水回り空間の壁や床等を構築する耐水性複合板に関するものである。   The present invention relates to a water-resistant composite board for constructing walls and floors of a water space.

従来、耐水性の有る下地板としては、発泡ポリスチレン板（非特許文献１）等の有機系発泡板や、セメントボード（特許文献１）等の無機系板がある。
ＪＩＳ Ａ ９５１１ 特許第２６７３９２７号公報参 Conventionally, as a base plate having water resistance, there are an organic foam plate such as a foamed polystyrene plate (Non-Patent Document 1) and an inorganic plate such as a cement board (Patent Document 1).
JIS A 9511 Refer to Japanese Patent No. 2673927

有機系発泡板は、優れた断熱性を有するものの局部的に荷重が加わったとき窪んだりして変形するため、局部荷重に弱い問題がある。また、無機系板は、軽量化のために肉厚を薄くすると曲げ剛性が小さくなり過ぎ、水回り空間の壁や床等を構築する耐水性下地材としの強度が不足す問題が生じ、逆に、肉厚を厚くすると重くなり、施工性が低下する問題が生じる。   Although the organic foam plate has excellent heat insulating properties, it has a problem that it is weak against local load because it is depressed and deformed when a load is locally applied. In addition, if the thickness of the inorganic board is reduced in order to reduce the weight, the bending rigidity becomes too small, resulting in a problem of insufficient strength as a water-resistant base material for constructing walls and floors of water-filled spaces. In addition, when the wall thickness is increased, it becomes heavier and the workability is degraded.

そこで、本発明は、従来の前記問題に鑑み創案したものであって、局部荷重に強く且つ重量を増大させることなく全体の肉厚を厚くして、水回り空間の壁，床又は天井等を構築する耐水性下地材として最適な耐水性複合板の提供を目的とする。   Therefore, the present invention was devised in view of the conventional problems described above, and is strong against local load and thickened without increasing the weight, so that the wall, floor, ceiling, etc. An object is to provide a water-resistant composite board optimal as a water-resistant base material to be constructed.

水回り空間の壁や床等を構築するのに最適な耐水性下地材を得るために本発明が採用した手段は、耐水性が有り吸水性のない有機系発泡板と、耐水性の有る仕上材接着用下地板を耐水性の有る接着剤で接合したことを特徴とする耐水性複合板である。前記仕上材接着用下地板に複数枚の無機質の仕上板を接着剤のみで接合したものとすることもある。この耐水性複合板は、水回り空間の壁，床，天井等を構築するための内装用の面材とすることもある。ここで言う水回り空間とは、浴槽，洗面器，流し台，便器，洗濯機，給湯器又は温水器等の水を扱う設備品を備えた浴室，洗面室，調理室，トイレ室，洗濯室又は設備室等がある。   The means adopted by the present invention in order to obtain an optimal water-resistant base material for constructing walls and floors in the water space are an organic foam plate that is water-resistant and has no water absorption, and a water-resistant finish. It is a water-resistant composite board characterized in that a base plate for material adhesion is joined with an adhesive having water resistance. A plurality of inorganic finishing plates may be joined to the finishing material bonding base plate only with an adhesive. This water-resistant composite board may be used as a surface material for interiors for constructing walls, floors, ceilings, etc. in the water space. The water space here means a bath, a washroom, a cooking room, a toilet room, a laundry room, or a bathroom equipped with water handling equipment such as a bathtub, washbasin, sink, toilet, washing machine, water heater or water heater. There are equipment rooms.

本発明に係る耐水性複合板は、有機系発泡板と耐水性の有る仕上材接着用下地板を耐水性の有る接着剤で接合して一体化してあるので、全体として断熱性や耐水性に優れていると共に、全体の肉厚を厚くすることで仕上材接着用下地板単体に比べて曲げ剛性を大きくできる。また、本発明に係る耐水性複合板は、全体の肉厚を厚くしても有機系発泡板を用いているため、仕上材接着用下地板単体で肉厚を厚くした場合に比べ全体の重量を著しく増大させることもない。更に、本発明に係る耐水性複合板は、仕上材接着用下地板の表面にタイル等の仕上材を接着できると共に、全体の肉厚を厚くすることで、施工時に自立させることも可能となる。   The water-resistant composite plate according to the present invention is integrally formed by joining an organic foam plate and a water-resistant finishing material bonding base plate with a water-resistant adhesive, so that the heat resistance and water resistance as a whole are improved. In addition to being excellent, bending rigidity can be increased by increasing the overall wall thickness as compared with the base plate for finishing material adhesion. In addition, the water-resistant composite plate according to the present invention uses an organic foam plate even if the overall thickness is increased, so that the overall weight is larger than when the finish plate adhesive base plate alone is increased in thickness. Is not significantly increased. Further, the water-resistant composite board according to the present invention can adhere a finishing material such as a tile to the surface of the finishing material bonding base plate, and can be made independent during construction by increasing the overall thickness. .

Similar to the apron 19, both the wall panels 20 and 21 are obtained by bonding a finishing plate 13 such as a tile to the base plate 15 of the composite plate 12 of the present invention, and the finishing plate 13 faces the interior of the bathroom 1. It is like that.

前記本発明複合板１２は、前記洗い場領域３に採用する以外に、図１に示す隣室４である脱衣室や洗面室等の水回り空間を形成する床、壁又は天井を構築するための内装用の面材として採用することも勿論可能である。例えば、隣室４の床に採用するときには、根太固定した木質合板等からなる下地板の上に本発明複合板１２を載設すると共に、本発明複合板１２の下地板１５の表面に配列したタイル等の仕上材１３を接着する。   The composite board 12 of the present invention is an interior for constructing a floor, wall, or ceiling that forms a water space such as a dressing room or a washroom which is the adjacent room 4 shown in FIG. Of course, it is also possible to employ it as a face material for use. For example, when employed in the floor of the adjacent room 4, the composite board 12 of the present invention is placed on a base board made of wood plywood or the like fixed with joists, and tiles arranged on the surface of the base board 15 of the composite board 12 of the present invention. A finishing material 13 such as is adhered.

前記本発明複合板１２は、有機系発泡板１４と耐水性の有る仕上材接着用下地板１５を耐水性の有る接着剤１６で接合して一体化してあるので、全体として断熱性や耐水性に優れていると共に、全体の肉厚を厚くすることで仕上材接着用下地板単体に比べて曲げ剛性を大きくできる。また、本発明複合板１２は、全体の肉厚を厚くしても有機系発泡板１４を用いているため、仕上材接着用下地板単体で肉厚を厚くした場合に比べ全体の重量を著しく増大させることもない。本発明複合板１２は、有機系発泡板１４を用いているので、保温性にも優れている。更に、本発明複合板１２は、仕上材接着用下地板１５の表面にタイル等の仕上材１３を接着できると共に、全体の肉厚を厚くすることで、エプロン１９や壁パネル２０，２１を施工時に自立させることも可能となる。   The composite plate 12 of the present invention is formed by joining the organic foam plate 14 and the water-resistant finishing material bonding base plate 15 with a water-resistant adhesive 16 so that the heat insulation and water resistance as a whole are integrated. In addition, the bending rigidity can be increased by increasing the overall wall thickness as compared with the base plate for finishing material adhesion alone. Further, since the composite plate 12 of the present invention uses the organic foamed plate 14 even if the overall thickness is increased, the overall weight is remarkably increased compared to the case where the thickness is increased only by the base plate for finishing material adhesion. There is no increase. Since the composite foam plate 12 of the present invention uses the organic foamed plate 14, it has excellent heat retention. Further, the composite plate 12 of the present invention can attach the finishing material 13 such as tiles to the surface of the finishing material bonding base plate 15 and increase the overall thickness, thereby constructing the apron 19 and the wall panels 20 and 21. Sometimes it is possible to be independent.
