Description

本発明は、少なくとも一方の構成部材と他方の構成部材を組み合わせて構成される天井材であって、主に浴室の天井を構成するプラスチック製天井材に関するものである。   The present invention relates to a ceiling material configured by combining at least one component member and the other component member, and mainly relates to a plastic ceiling material that constitutes a ceiling of a bathroom.

一対の構成部材を突き合わせ状に連結して構成されるプラスチック製天井材は、特開２００３−１６０９９６公報に記載されている。
特開２００３−１６０９９６公報 Japanese Unexamined Patent Publication No. 2003-160996 discloses a plastic ceiling material formed by connecting a pair of constituent members in a butted manner.
JP 2003-160996 A

特許文献１に記載されている天井材は、互いに突き合わせ状に連結される構造であって、その突き合わせ端面に凹凸嵌合構造をともなったものであるが、その接続構造は、一辺に沿った側端面のみを部分的に重ね合わせているものであるから、両者の全体的なあわせ具合があまり良くないものであり、また接合部の面が垂直のために結合ボルトが水平になり組み立てにくいものであった。   The ceiling material described in Patent Document 1 is a structure that is connected to each other in a butt-like manner, and has a concavo-convex fitting structure on the butt end surface, but the connection structure is a side along one side. Since only the end faces are partially overlapped, the overall fit of the two is not very good, and the joining bolts are horizontal and difficult to assemble because the joint faces are vertical. there were.

そこで本発明は、一対の構成部材を組み合わせて構成される天井材であっても、接合部が被さるように組み合わせる構造として、組立時にねじで固定する前でも離れ難く、また接合部の面が傾斜しているためにねじの組み立てが容易であるうえ、水平方向の仮の位置決めができて組み立て易いプラスチック製天井材を提供することを目的とするものである。   Therefore, the present invention is a ceiling material configured by combining a pair of structural members, so that it is difficult to separate even before fixing with a screw at the time of assembly as a structure to be combined so that the joint is covered, and the surface of the joint is inclined. Therefore, it is an object of the present invention to provide a plastic ceiling material that is easy to assemble screws and that can be temporarily positioned in the horizontal direction and is easy to assemble.

上記目的を達するための本発明の請求項１に係るプラスチック製天井材は、少なくとも一対の、天面およびそれに連なる側面よりなる構成部材を組み合わせて構成される、ブロー成形により一体に形成される天井材であって、一対の構成部材は重ね合わせ状に接合されるように、一方の構成部材には張出した山形の膨出部を有する突起部の斜面に接合面があり、他方の構成部材には一方の構成部材の前記接合面に被さるように取り付けフランジ部をもつと共に、 一方の構成部材の張出した突起部には段部が形成され、他方の構成部材には一方の構成部材の前記段部に対応した段部が形成されており、他方の構成部材のフランジ部が、一方の構成部材の突起部を囲むように組み合わされ、一方の構成部材の段部と反対側の傾斜面と他方の構成部材の段部と反対側の傾斜面とがネジで固定されて天井材が構成されていることを特徴とするものである。 To achieve the above object, a plastic ceiling material according to claim 1 of the present invention is a ceiling integrally formed by blow molding , which is composed of a combination of at least a pair of structural members including a top surface and side surfaces connected to the top surface. The one component member has a bonding surface on the slope of the protruding portion having a protruding ridge- shaped bulge so that the pair of component members are joined in an overlapping manner, and the other component member Has a mounting flange portion so as to cover the joint surface of one component member, and a protruding portion of one component member has a stepped portion, and the other component member has the step portion of one component member. A step portion corresponding to the step portion is formed, and the flange portion of the other component member is combined so as to surround the projection portion of the one component member, and the inclined surface on the side opposite to the step portion of the one component member and the other Components The ceiling portion is configured by fixing the stepped portion of the material and the inclined surface on the opposite side with a screw .

本発明の請求項２に係るプラスチック製天井材は、請求項１記載の構成において、天井材の中空部にはその一部又は全体に発泡材が充填されていることを特徴とするものである。 The plastic ceiling material according to claim 2 of the present invention is characterized in that, in the structure according to claim 1 , the hollow portion of the ceiling material is partially or entirely filled with a foam material. .

本発明によれば、一対の構成部材を組み合わせて構成される天井材であっても、接合部が被さるように組み合わせる構造として、組立時にネジで固定する前でも離れ難く、また接合部の面が傾斜しているためにねじの組み立てが容易であるうえ、水平方向の仮の位置決めができて組み立て易く、一方の構成部材と他方の構成部材との連結施工を簡便かつ的確にできる効果が得られる。   According to the present invention, even if it is a ceiling material configured by combining a pair of constituent members, it is difficult to separate even before fixing with screws at the time of assembly as a structure to be combined so that the joint is covered, and the surface of the joint is Since it is inclined, it is easy to assemble screws, and it is easy to assemble by temporarily positioning in the horizontal direction, and it is possible to obtain an effect that can easily and accurately connect one component member to the other component member. .
