Description

【０００１】
【発明の属する技術分野】
本発明は壁パネルの連結構造に関するものである。
【０００２】
【従来の技術】
従来浴室ユニット等の壁パネルとしては、鋼板を折り曲げて形成したもの、あるいは金属製の枠にセメント系の面板を取着したもの、あるいは金属製の枠に合成樹脂製の面板を取着したものがある。
【０００３】
鋼板を折り曲げて壁パネルを構成したものは、鋼板製の面板部の側端部を折り曲げて鋼板製の側枠部を形成したものであり、この鋼板製の側枠部部分において壁パネル同士を連結するための連結部材に連結していた。
【０００４】
また、金属製の枠にセメント系の面板を取着した壁パネルや金属製の枠に合成樹脂製の面板を取着した壁パネルにおいては、金属製の枠部分において壁パネル同士を連結するための連結部材に連結していた。
【０００５】
しかしながら、前者の従来例にあっては、鋼板を折り曲げて形成したものであるから、側枠部の先端が鋼板の切断端面となってこの部分から錆が発生しやすいという問題がある。更に、鋼板の切断端面が露出すると壁パネルの運搬、施工の際に手などを傷付けるおそれがある。また、鋼板であるため、冷たい感じがして浴室の壁パネルとしてあまり好ましくない。
【０００６】
また、後者の従来例にあっては、金属製の枠に面板を取着して壁パネルを形成している
ため、壁パネルの形成が面倒で、製造コストが高くなるという問題があり、また、枠と面板との取着部分が防水上完全でないとこの部分から水が染み出るという問題があり、更に、枠に面板を取着するための接着剤が面板の表面側に流れ出ると商品価値が低下してしまうという問題がある。
【０００７】
そこで、本発明者は本発明に至る過程で面板部の側端部に背方に向けて側枠部を突設した壁パネルを合成樹脂により一体に成形することを考えた。これだと、合成樹脂の一体成型により壁パネルを形成できるので、錆のおそれがなく、外観もよく、更に、金属製の枠を後工程で取着する必要もなく、生産性が向上するものである。
【０００８】
しかしながら、合成樹脂で一体成形した壁パネルにおいては面板の側端部から背方に突出した側枠部が合成樹脂であるため従来の金属の枠に比べて強度が劣り、変形しやすいという問題があった。特に、壁パネルは大型であるため、運搬、施工の際に側端部の合成樹脂製の側枠部が変形しやすいものである。また、合成樹脂製の側枠部は側枠部自体が変形しやすいだけでなく、側枠部の突出基部であるコーナ部分から変形しやすいという問題があり、また、連結の際にコーナ部分に力が作用すると変形だけでなくクラックが生じたりするおそれがあり、このものにおいては、施工した際に、外観が悪く、連結部材との連結強度が弱いだけでなく、変形していると側枠部と目地材との密着が均一でなくて変形箇所から水漏れが生じたりするおそれもある。
【０００９】
【発明が解決しようとする課題】
本発明は上記の点に鑑みてなされたものであり、壁パネルを合成樹脂により一体成形することで、外観が向上し、錆が発生せず、生産性が向上し、しかも、連結部材との連結の際に側枠部や側枠部と面板部とのなすコーナ部分の変形やクラックの発生を防止して確実且つ強固に連結できる壁パネルの連結構造を提供することを課題とするものである。
【００１０】
【課題を解決するための手段】
上記課題を解決するために本発明に係る壁パネルの連結構造は、面板部１の側端部に背方に向けて一体に側枠部２を突設した壁パネル３を合成樹脂により一体に形成し、この合成樹脂製の壁パネル３の面板部１の側枠部２側端部と側枠部２をコーナ部を含めて面板部１の他の部分よりも肉厚の厚い厚肉補強部４とし、側枠部の内面部に壁パネルと一体に成形された係止突起を突設し、隣接する合成樹脂製の壁パネル３の隣接する側枠部２をそれぞれ連結部材５の連結用溝７に嵌め込むと共に各側枠部２の内面部の係止突起６をそれぞれ連結用溝７の両内側面部の被係止突起８に係止する壁パネルの連結構造であって、被係止突起８の一端を係止突起６に係止すると共に被係止突起８の他端を面板部１の厚肉補強部４を構成する側枠部２側端部の背面に当接して成ることを特徴とするものである。このような構成とすることで、壁パネル３を合成樹脂により一体成形できて壁パネル３の外観が向上し、錆が発生せず、生産性が向上し、しかも、合成樹脂の一体成形品であるにもかかわらず、連結部材５との連結部分である側枠部２が肉厚の厚い厚肉補強部４であるので側枠部２の変形を防止しながら連結部材５との連結、特に、厚肉補強部４の一部を構成する側枠部２の内側面に断面山形形状をした係止突起６と、連結部材５の連結用溝７の内側面部の被係止突起８との係止が確実且つ強固にできるだけでなく、面板部１の側枠部２側の端部とコーナ部も肉厚の厚い厚肉補強部４であるため、側枠部２の突出基部部分であるコーナ部付近における変形やクラックを防止できるものである。また、壁パネル３の側枠部２を連結溝用７に前方より嵌め込んで係止突起６を被係止突起８に係止することで簡単に壁パネル３を側枠部２に連結できるものである。更には被係止突起８の一端を係止突起６に係止すると共に被係止突起８の他端を面板部１の厚肉補強部４を構成する側枠部２側端部の背面に当接したものにおいては、係止がより確実で安定し、しかもコーナ部及び面板部１の側枠部２側の端部の変形を防止することができるものである。
【００１１】
【発明の実施の形態】
以下、本発明を添付図面に示す実施形態に基づいて説明する。
【００１２】
面板部１の側端部に背方に向けて一体に側枠部２を突設し、更に、面板部１の背面には補強リブ９が突設してあり、上記側枠部２の内面部には断面山形形状をした係止突起６が突設してあって、壁パネル３が構成してあり、この壁パネル３はＦＲＰのような合成樹脂
の一体成形品である。
【００１３】
上記のように合成樹脂により一体に形成した壁パネル３において、本発明においては、合成樹脂製の壁パネル３の面板部１の側枠部２側端部と側枠部２をコーナ部を含めて面板部１の他の部分よりも肉厚の厚い厚肉補強部４としてある。つまり、図１においてクロスハッチングで示す面板部１の側枠部２側端部と、側枠部２とで構成されるコーナ部を含む壁パネル３の端部の断面Ｌ形の部分の肉厚ｔ１を面板部１の他の部分の肉厚ｔ２よりも厚くしてある。
【００１４】
上記のような構成の合成樹脂により一体成形した壁パネル３は例えば浴室ユニットの壁を構成するための壁パネルとして用いるものであり、合成樹脂製の壁パネル３を厚肉の側枠部２部分において隣接する合成樹脂製の壁パネル３同士を連結するための連結部材５に取付けるものである。
【００１５】
連結部材５は図２に示すように、断面コ字状をした金属製の縦長の補強スタッド５ａの溝内に断面コ字状をした金属製の縦長の連結スタッド５ｂを配設固着して構成してある。連結スタッド５ｂは弾性を有する金属板をコ字状に屈曲して構成してあり、連結スタッド５ｂの両側片の先端部を更に内側に２重に折り返してあって先端面が内側に巻き込まれて外に露出しないようにしてある。断面コ字状の連結スタット５ｂの内部は前方に開口した連結用溝７となっており、上記連結スタット５ｂの先端部の折り曲げ部分が連結用溝７の両内面部において突出していて被係止突起８となっている。
【００１６】
浴室ユニットは図３に示すように床パン１３を設置した後、床パン１３の外周の立ち上がり部の上端部の載置部１４に複数の壁パネル３を載置して建て込んで浴室ユニットの壁を構成し、その後、天井パネル（図示せず）を取付けて構成するものである。
【００１７】
ここで、縦長の連結部材５は上記載置部１４上に所定間隔を隔てて複数立設するものであり、連結部材５の下端部間、上端部間をそれぞれ下つなぎ材１５、上つなぎ材１６で連結する。
【００１８】
そして、上記のように複数個の連結部材５が所定間隔を隔てて複数本立設されるのであるが、合成樹脂製の壁パネル３は所定間隔を隔てて位置する２つの連結部材５間に配置し、合成樹脂製の壁パネル３を前方から押し込むようにして壁パネル３の両側の側枠部２を両側の連結部材５の連結用溝７にそれぞれ嵌め込んで両側の側枠部２の内面部の係止突起６をそれぞれ両側の連結用溝７の一方の内側面部の被係止突起８に係止するものである。このようにして次々と合成樹脂製の壁パネル３を側枠部２部分で連結部材５に連結するものである。
【００１９】
ここで、１つの連結部材５においては、図２に示すように連結スタット５ｂの前方に開口した連結用溝７内に隣接する合成樹脂製の壁パネル３の隣接する側枠部２をそれぞれ連結部材５の連結用溝７に嵌め込むと共に各側枠部２の内面部の係止突起６をそれぞれ連結用溝７の両内側面部の被係止突起８に係止されることになる。連結用溝７に嵌め込まれた隣接する合成樹脂製の壁パネル３の隣接する側枠部２間には乾式の目地材１７が嵌め込まれて両壁パネル３の隣接する側枠部２間から水漏れが生じないようにしている。
【００２０】
ところで、上記のようにして合成樹脂製の壁パネル３の側枠部２を連結部材５を構成する連結スタット５ｂに連結するに当たり、図１、図２においてクロスハッチングで示す面板部１の側枠部２側端部と、側枠部２とで構成されるコーナ部を含む壁パネル３の端部の断面Ｌ形の部分を厚肉補強部４としてあるので、側枠部２の変形を防止しながら連結部材５との連結が確実且つ強固にできるだけでなく、面板部１の側枠部２側の端部とコーナ部も肉厚の厚い厚肉補強部４であるため、側枠部２の突出基部部分であるコーナ部付近における変形やクラックを防止でき、これにより、壁パネル３を合成樹脂により一体成形したものを使用して連結部材５で連結しても従来の金属の枠と同様に連結できるものである。特に、図２のように被係止突起８が一端が厚肉補強部４である側枠部２の内面に突設した係止突起６に係止し、更に、被係止突起８の他端が面板部１の端部の背面にも当接係止する構造のものにおいては、面板部１の側枠部２側の端部とコーナ部も肉厚の厚い厚肉補強部４であるため、係止がより確実で安定し、しかもコーナ部及び面板部１の側枠部２側の端部の変形を防止することができるものである。
【００２１】
なお、本発明の合成樹脂により一体成形した壁パネル３には図に示すように背面側に必要に応じてウレタン等の断熱層１０を充填して断熱性を高めるようにしてもよい。図において符号１１はバックシートである。

【発明の効果】
上記のように本発明の請求項１記載の発明にあっては、面板部の側端部に背方に向けて一体に側枠部を突設した壁パネルを合成樹脂により一体に形成し、この合成樹脂製の壁パネルの面板部の側枠部側端部と側枠部をコーナ部を含めて面板部の他の部分よりも肉厚の厚い厚肉補強部とし、側枠部の内面部に壁パネルと一体に成形された係止突起を突設し、隣接する合成樹脂製の壁パネルの隣接する側枠部をそれぞれ連結部材の連結用溝に嵌め込むと共に各側枠部の内面部の係止突起をそれぞれ連結用溝の両内側面部の被係止突起に係止してあるので、壁パネルを合成樹脂により一体成形できて外壁パネルの外観が向上し、錆が発生せず、生産性が向上するものである。しかも、このように壁パネルが合成樹脂の一体成形品であるにもかかわらず、連結の際の側枠部、コーナ部、面板部の端部の変形やクラックを防止しながら連結部材との連結が確実且つ強固にできるものである。つまり、面板部の側枠部側端部と側枠部をコーナ部を含めて厚肉となった厚肉補強部とすると共に厚肉補強部の一部を構成する側枠部の内側面に断面山形形状をした係止突起を突設してあるので、厚肉補強部の一部を構成する側枠部の内面部に突設した係止突起と、連結部材の連結用溝の内側面部の被係止突起の係止が側枠部、コーナ部、面板部の端部の変形やクラックを防止しながら確実且つ強固にできるものであり、これにより、壁パネルを合成樹脂により一体成形したものを使用して連結部材で連結しても従来の金属の枠と同様に連結できるものである。また、壁パネルの側枠部２を連結溝用に前方より嵌め込んで係止突起を被係止突起に係止することで簡単に壁パネルを側枠部に連結できるものである。また被係止突起の一端を係止突起に係止すると共に被係止突起の他端を面板部の厚肉補強部を構成する側枠部側端部の背面に当接するので、係止がより確実で安定し、しかもコーナ部及び面板部の側枠部側の端部の変形を防止することができる。

However, since the former conventional example is formed by bending a steel plate, there is a problem that the tip of the side frame portion becomes a cut end surface of the steel plate and rust is likely to be generated from this portion. Furthermore, if the cut end face of the steel plate is exposed, there is a risk of damaging a hand or the like during transportation and construction of the wall panel. Moreover, since it is a steel plate, it feels cold and is not so preferable as a wall panel of a bathroom.
[0006]
Moreover, in the latter conventional example, since the wall panel is formed by attaching the face plate to the metal frame, there is a problem that the formation of the wall panel is troublesome and the manufacturing cost becomes high, In addition, there is a problem that water is oozed out from this part when the attachment part between the frame and the face plate is not waterproof, and further, if the adhesive for attaching the face plate to the frame flows out to the surface side of the face plate, the product value There is a problem that will decrease.
[0007]
In view of this, the present inventor considered that a wall panel in which a side frame portion protrudes from the side end portion of the face plate portion toward the back in the course of the present invention is integrally formed with a synthetic resin. This makes it possible to form a wall panel by integral molding of synthetic resin, so there is no risk of rust, good appearance, and there is no need to attach a metal frame in a later process, improving productivity It is.

However, in the wall panel integrally molded with synthetic resin, the side frame portion protruding backward from the side edge of the face plate is made of synthetic resin, so the strength is inferior compared to a conventional metal frame, and there is a problem that it is easily deformed. there were. Particularly, since the wall panel is large, the side frame portion made of synthetic resin at the side end portion is easily deformed during transportation and construction. In addition, the side frame made of synthetic resin not only tends to deform itself, but also has a problem that it easily deforms from the corner part that is the protruding base of the side frame part. If a force is applied, there is a risk of not only deformation but also cracking. In this case, when it is constructed, not only the appearance is poor and the connection strength with the connection member is weak, but also the side frame when it is deformed There is also a possibility that the contact between the part and the joint material is not uniform, and water leaks from the deformed portion.
[0009]
[Problems to be solved by the invention]
The present invention has been made in view of the above points, and by integrally molding the wall panel with a synthetic resin, the appearance is improved, rust is not generated, productivity is improved, and the connection member is It is an object of the present invention to provide a wall panel connection structure that can be securely and firmly connected by preventing deformation and cracking of a corner portion formed by a side frame portion or a side frame portion and a face plate portion at the time of connection. is there.
