Abstract
Description
本発明は、床材、天井、天井などの建築内装用化粧板であって、複数の矩形部材を連接して広い面を施工可能とする化粧板に関する。 The present invention relates to a decorative board for building interior such as a flooring material, a ceiling, and a ceiling, and relates to a decorative board that allows a wide surface to be constructed by connecting a plurality of rectangular members.
従来、上記のような化粧材の構成では、その端面を図２で示すような連結構造として組み合わせていくものが知られている。しかしながらこのような構造である場合、嵌合はずれや水の浸入といった問題が発生していた。 Conventionally, in the configuration of the decorative material as described above, it is known that end surfaces thereof are combined as a connection structure as shown in FIG. However, in such a structure, problems such as disengagement and water intrusion have occurred.
それに対して、化粧板基材の両面下部に凹部を設けて連結部材でこれらを連結する方法も知られている。しかしながら、このような場合であっても、先の場合より顕著ではないものの、嵌合はずれや水の浸入は避けられないものであった。
本発明はこのような問題点を解決するためになされたものであり、その課題とするところは、嵌合はずれや水の浸入の問題のない化粧板を得ることにある。 The present invention has been made to solve such problems, and the object of the present invention is to obtain a decorative board free from problems of disengagement and water intrusion.
本発明はこの課題を解決するものであり、すなわちその請求項１記載の発明は、底板部の両側に上向きの突出部を備えたコ字状の連結部材によって隣り合う化粧板基材が連結される化粧板において、前記突出部が傘状であり、前記突出部により嵌合されるような係止溝が、化粧板基材の両端部の幅方向の裏面に設けてなり、前記化粧板基材の弾性率は１９００〜４０００ＭＰａであり、前記突出部と前記係止溝の隙間をａとしたときに、化粧板どうしの隙間を２ａとなるように設け前記隙間ａが０．２〜０．７ｍｍであり、前記突出部の傘状の最大幅をＡ、最小幅をＢとしたときにＡ−Ｂが０．０５〜０．５ｍｍとなるように設けてなることを特徴とする化粧板である。 The present invention solves this problem. That is, in the invention according to claim 1, adjacent decorative plate base materials are connected by U-shaped connecting members having upward projecting portions on both sides of the bottom plate portion. In the decorative board, the protruding portion is umbrella-shaped, and a locking groove to be fitted by the protruding portion is provided on the back surface in the width direction of both end portions of the decorative plate base. The elastic modulus of the material is 1900 to 4000 MPa, and when the clearance between the protruding portion and the locking groove is a, the clearance between the decorative plates is 2a, and the clearance a is 0.2 to 0. A decorative board characterized in that it is 7 mm and is provided so that A-B is 0.05 to 0.5 mm when the maximum width of the umbrella-shaped protrusion is A and the minimum width is B. is there.
本発明により、嵌合時の破損がなく、嵌合後も嵌合はずれや水の侵入といった問題も発生することがない化粧板を提供することが可能になるという効果を奏する。 According to the present invention, there is an effect that it is possible to provide a decorative board that is not damaged at the time of fitting and that does not cause problems such as disengagement or intrusion of water even after fitting.
以下、本発明を図面に基づき詳細に説明する。図１に本発明の化粧板の一実施例の断面の構造を示す。

本発明における化粧板基材１は、弾性率が１９００〜４０００ＭＰａのものが用いられる。具体的には、ポリオレフィン系樹脂に木粉その他の充填剤、添加剤を添加して得られる木質系樹脂を異型押出成形にて成形するものが好適に用いられ、その際に意匠的に問題のない範囲でその添加割合を調整すれば良い。具体的には、ホモポリプロピレン８０重量部にマレイン酸変成ポモポリプロピレン２０重量部を混合したものに平均粒径１００μｍに粉砕した木粉を１００重量部添加してなるものが好適である。 As the decorative board substrate 1 in the present invention, one having an elastic modulus of 1900 to 4000 MPa is used. Specifically, it is suitable to use a wood-based resin obtained by adding wood powder or other fillers and additives to a polyolefin-based resin by profile extrusion molding. What is necessary is just to adjust the addition ratio in the range which is not. Specifically, a mixture of 80 parts by weight of homopolypropylene mixed with 20 parts by weight of maleic acid-modified pomopolypropylene and 100 parts by weight of wood powder ground to an average particle size of 100 μm is preferable.
本発明における係止溝２は、化粧板基材１の成形時に設けるものでもよいし、成形後に切削加工により設けても良い。 The locking groove 2 in the present invention may be provided when the decorative board substrate 1 is molded, or may be provided by cutting after molding.
本発明における連結部材３は、化粧板基材と同様の材料、同様の方法により成形するのが好適であるが、特にこれに限定するものではなく、同様の弾性率と求める範囲の形状のものが得られれば良い。 The connecting member 3 in the present invention is preferably formed by the same material and the same method as the decorative board base material, but is not particularly limited to this, and has the same elastic modulus and the required shape. If it is obtained.
本発明における傘状突起４は、連結部材３の成形時に設けるものでもよいし、成形後に切削加工により設けても良い。 The umbrella-shaped protrusion 4 in the present invention may be provided when the connecting member 3 is formed, or may be provided by cutting after forming.
