Abstract

<P>PROBLEM TO BE SOLVED: To provide a wall panel connection structure which exhibits excellent design, contributes to shortening of the construction period, and ensures high water cutoff performance by preventing infiltration of water caused by capillarity. <P>SOLUTION: The wall panel 1 connection structure is obtained by vertically abutting a plurality of wall panels 1 (1A, 1B) each having a projection 10a on one vertical end face thereof and a recess 11a in the other vertical end thereof, on each other by tongue and groove fitting. Each wall panel 1 has a step portion 10b at the tip of the projection 10a formed thereon, and a space S for eliminating the capillarity, in a tongue and groove fitting portion between the adjacent wall panels 1A, 1B. According to the wall panel connection structure, the capillarity is eliminated by the space S formed in the tongue and groove fitting portion, and therefore the high cutoff performance is ensured at the tongue and groove fitting portion between the wall panels 1A, 1B, which positively prevents water leakage to the outside of the wall panels 1A, 1B. Accordingly, water-proofing of the wall panels by using caulking materials or joint members is dispensed with, which leads to shortening of the construction period. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

【発明の属する技術分野】
本発明は、ユニットバスの壁面等の構築に適用される壁パネルの結合構造であって、更に詳細には上下端面の一方に凸部を他方に凹部を形成して成る複数の壁パネルを凹凸嵌合によって上下方向に積み重ねて結合する壁パネルの結合構造に関するものである。
【0002】
【従来の技術】
例えば、ユニットバスの壁面を構築する形態として、図6に示すように、縦長の複数の壁パネル101を左右方向に結合する方式が採用されていた。この方式では、図7に示すように、壁パネル101の裏面又は木口面に取り付けられたジョイント部品113,114を用いて、隣り合う壁パネル101同士が図8に示すように結合される。尚、図7は結合前、図8は結合後の壁パネル101の部分横断面図(図6のB−B線断面図)である。
【0003】
ところが、上記方式では、図8(a)に示すように壁パネル101の厚み公差によって壁パネル101の表面に段差Δtが生じたり、同図(b)に示すようにジョイント部品113,114の取付公差によって壁パネル101の表面に段差Δaが生じるという問題があった。
【0004】
又、ジョイント部品113,114は壁パネル101の高さ方向に部分的に嵌合されるため、壁パネル101が反っている場合には、ジョイント部品113,114が無い部分では壁パネル101の表面に段差が生じていた。
【0005】
更に、壁パネル101間の目地の幅が広いために意匠性が悪いという問題があった。
【0006】
又、図8に示すように、壁パネル101間の目地部をコーキング材115や目地材等で止水処理しているが、見え掛かり面にパネル意匠とは別の意匠であるコーキング材115が存在するために意匠性が損なわれる他、コーキング材115や目地材等による止水処理を要するため、コーキング材115の塗布、目地材の嵌め込み等の作業が必要となり、施工時間が長くなるという問題があった。
【0007】
そこで、図9に示すように、上下端面の一方に凸部210aを他方に凹部211aを形成して成る複数の壁パネル201を凹凸嵌合によって上下方向に積み重ねて結合する方式が提案されている(例えば、特開平10−311111号、特開平6−42075号公報参照)。
【0008】
【発明が解決しようとする課題】
しかしながら、上記提案に係る壁パネル結合構造においては、隣り合う壁パネル201の凹凸嵌合部の隙間から水が毛細管現象によって浸入するために止水性が悪く、壁パネル201外部への漏水が発生するという問題があった。
【0009】
本発明は上記問題に鑑みてなされたもので、その目的とする処は、高い意匠性の確保と施工時間の短縮を図りつつ、毛細管現象による水の浸入を防いで高い止水性を確保することができる壁パネルの結合構造を提供することにある。
【0010】
【課題を解決するための手段】
上記目的を達成するため、請求項1記載の発明は、上下端面の一方に凸部を他方に凹部を形成して成る複数の壁パネルを凹凸嵌合によって上下方向に積み重ねて結合する壁パネルの結合構造において、前記各壁パネルに形成された凸部の頂部に段部を形成し、隣り合う壁パネルの凹凸嵌合部内に、毛細管現象をカットするための空間を形成したことを特徴とする。
【0011】
従って、請求項1記載の発明によれば、隣り合う壁パネルの凹凸嵌合部内に形成された空間によって毛細管現象がカットされるため、壁パネルの凹凸嵌合部に高い止水性が確保され、壁パネル外部への漏水が確実に防がれる。従って、コーキング材や目地材を用いた止水処理が不要となり、施工時間を短縮することができるとともに、壁パネルの目地部にコーキング材や目地材等が存在せず、更に凹凸嵌合によって壁パネルに段差が発生しないため、見た目に美しく、高い意匠性が確保される。
【0012】
又、複数の壁パネルが凹凸嵌合によって上下方向に積み重ねて結合されるため、壁パネル間の目地幅が小さく抑えられて清掃性が高められるとともに、目地部をコーキングしないためにカビの発生が抑えられる。
【0013】
更に、壁パネルに反りがあっても、凹凸嵌合によって反りが矯正されるため、壁パネル間の段差が解消されて高い意匠性が確保される。
【0014】
請求項2記載の発明は、請求項1記載の発明において、前記各壁パネルの上端面に凸部を、下端面に凹部を形成したことを特徴とする。
【0015】
従って、請求項2記載の発明によれば、壁パネルの凹凸嵌合部での止水効果が更に高められる。
【0016】
請求項3記載の発明は、請求項1又は2記載の発明において、前記凸部と凹部を壁パネルの表面を基準として形成したことを特徴とする。
【0017】
従って、請求項3記載の発明によれば、凸部と凹部が壁パネルの表面を基準として形成されるため、壁パネルの厚み公差等とは無関係に、隣り合う壁パネルの段差が解消されて高い意匠性が確保される。
【0018】
請求項4記載の発明は、請求項1〜3の何れかに記載の発明において、前記各壁パネルに形成された凸部の高さを凹部の深さよりも小さく設定したことを特徴とする。
【0019】
従って、請求項4記載の発明によれば、隣り合う壁パネル同士が上下方向に密着するため、両者間の目地幅が最小限に抑えられ、高い意匠性と止水性及び清掃性が確保される。
【0020】
請求項5記載の発明は、請求項4記載の発明において、隣り合う壁パネルの凹凸嵌合部の凹部と凸部との間に止水材を介設したことを特徴とする。
【0021】
従って、請求項5記載の発明によれば、壁パネルの凹凸嵌合部に形成された空間による毛細管現象のカットによる止水効果に、止水材による2次的な止水効果が加えられるため、水の浸入が一層確実に防がれる。
【0022】
【発明の実施の形態】
以下に本発明の実施の形態を添付図面に基づいて説明する。
【0023】
図1は本発明に係る壁パネルの結合構造を備えるユニットバスルームの斜視図である。
【0024】
図1に示すユニットバスルームにおいては、横長の複数の壁パネル1を本発明に係る結合構造によって上下方向に積み重ねて結合することによって側壁が構成されている。
【0025】
又、ユニットバスルームには、洗い場を構成する床面パネル2の長手方向に沿って浴槽3が配置され、床面パネル2には、不図示の排水口を覆う着脱可能な蓋4が設けられている。尚、浴槽3には水栓金具5が付属しており、側壁の一部には手摺6が縦方向に長く取り付けられている。
【0026】
次に、本発明に係る壁パネルの結合構造を図2〜図4に基づいて説明する。尚、図2〜図4は隣り合う壁パネルの嵌合端部の部分縦断面図であり、図2は結合前の状態、図3は結合中の状態、図4は結合後の状態(図1のA−A線断面図)をそれぞれ示す。
【0027】
図2において、1(1A),1(1B)は厚さ約20mm程度の前記壁パネルであって、各壁パネル1は、矩形板状の保温材7の両面を厚さ3〜5mmの薄い矩形板状の表面化粧板8と裏面板9でサンドイッチ状に挟み込んで接着し、その上下端部の表面化粧板8と裏面板9の間(保温材7が無い部分)に芯材10,11を挟み込んで接着することによって構成されている。ここで、保温材7は発泡スチロール(高発泡PS材)等で構成され、バスルーム側(表面側)に位置する表面化粧板8は化粧樹脂板や化粧鋼板等で構成され、外面側の裏面板9は樹脂板や鋼板等で構成され、芯材10,11はアルミニウム押出材や樹脂等で構成されている。
【0028】
而して、各壁パネル1(芯材10)の上端面の幅方向中央には凸部10aが長さ方向(横方向)全長に亘って一体に形成されており、同壁パネル1(芯材11)の下端面の幅方向中央には矩形溝状の凹部11aが長さ方向(横方向)全長に亘って形成されている。この場合、凸部10aと凹部11aは壁パネル1の表面(バスルーム側の化粧面)を基準として加工することによって形成されている。
【0029】
ここで、上記凸部10aの頂部の表面側(バスルーム側)の隅部には矩形状の段部10bが形成されており、凸部10aの高さh(本実施の形態では10mm)は凹部11aの深さd(本実施の形態では15mm)よりも小さく設定されている(h<d)。又、凹部11aの幅Bは凸部10aの幅bよりも僅か(本実施の形態では0.1〜0.3mm程度。即ち、B−b=0.1〜0.3mm)大きく設定されている(B>b)。
【0030】
更に、各壁パネル1の下端面の凹部11aを挟む部分において、裏面側の下端面aは表面側の下端面bよりも僅かに上方に位置しており、両者の間にはΔh(本実施の形態では0.2mm)の段差が形成されている。これに対して、各壁パネル1の上端面の凸部10aを挟む表面側と裏面側の端面c,dは同一高さ(つまり、面一)とされており、両者間に段差は設けられていない。
【0031】
次に、本発明に係る結合構造によって壁パネルを組み付ける要領について説明する。
【0032】
本発明に係る結合構造においては、下方の壁パネルの上に壁パネルが凹凸嵌合によって積み重ねられて結合される。即ち、図2〜図4に示す例について説明すると、既に結合された下方の壁パネル1Aの上端面には凸部10aが突出しており、この壁パネル1Aの上に壁パネル1Bを積み重ねて結合する際、図3に示すように、壁パネル1Bの下端面に形成された凹部11aに弾性材から成る止水材12が全幅に亘って嵌め込まれて貼り付けられる。尚、本実施の形態では、止水材12として厚さ10mmのゴム系のパッキンが用いられている。
【0033】
上述のように、結合すべき壁パネル1Bの凹部11aに止水材12を貼り付けると、図4に示すように、結合すべき壁パネル1Bの凹部11aを下方の壁パネル1Aの凸部10aに上方から嵌合すると、壁パネル1Bが凹凸嵌合によって下方の壁パネル1A上に積み重ねられて結合される。すると、止水材12が壁パネル1Aの凸部10aによって圧縮されて変形し、壁パネル1Bの凹部11a内で壁パネル1Aの凸部10aとの空間を全幅に亘って埋めて止水機能を果たす。又、壁パネル1Aの凸部10aの頂部には段部10bを形成したため、凹部11a内には毛細管現象をカットするための空間Sが長さ方向(横方向)全長に亘って形成される。
【0034】
ところで、前述のように凸部10aの高さh(=10mm)は凹部11aの深さd(=15mm)よりも小さく設定されており、壁パネル1Bの下端面の凹部11aを挟む端面a,bの間にはΔh(=0.2mm)の段差が形成されているため、壁パネル1Bの下端面と壁パネル1Aの上端面とは表面側(バスルーム側)においては密着し、裏面側には段差Δh分のガタが発生する。この結果、結合された壁パネル1A,1B間の目地幅が最小限に抑えられ、高い止水性及び清掃性が確保されるとともに、コーキング材や目地材を用いた止水処理が不要となるため、施工時間が短縮される。又、壁パネル1A,1Bの目地部にコーキング材や目地材等が存在しないため、カビの発生が抑えられる。
【0035】
又、前述のように、各壁パネル1において凹部11aの幅Bは凸部10aの幅bよりも僅か(0.1〜0.3mm程度)に大きく設定されているため、壁パネル1Bの凹部11aの壁パネル1Aの凸部10aへの嵌合が容易になされ、嵌合後の凹部11aと凸部10a間には図4に示すガタΔb(=0.1〜0.3mm)が発生する。
【0036】
以上と同様の要領によって複数の壁パネル1を凹凸嵌合によって上下方向に積み重ねて結合する作業を繰り返すことによって、図1に示すユニットバスルームの側壁が構築されるが、本発明によれば、上下の壁パネル1の凹凸嵌合部内に形成された空間Sによって毛細管現象がカットされるため、壁パネル1の凹凸嵌合部に高い止水性が確保され、壁パネル1外部への漏水が確実に防がれる。又、各壁パネル1の上端面に凸部10aを、下端面に凹部11aを形成したため、壁パネル1の凹凸嵌合部での止水効果が更に高められる。
【0037】
更に、上下の壁パネル1の凹凸嵌合部の凹部11aと凸部10aとの間に止水材12を介設したため、壁パネル1の凹凸嵌合部に形成された空間Sによる毛細管現象のカットによる前記止水効果に、止水材12による2次的な止水効果が加えられ、これによって水の浸入が一層確実に防がれる。
【0038】
又、各壁パネル1において、前述のように凸部10aと凹部11aを表面を基準として形成したため、壁パネル1の厚み公差等とは無関係に、上下の壁パネル1の段差が解消され、更に、壁パネル1に反りがあっても、凹凸嵌合によってその反りが矯正されるため、壁パネル1間の段差が解消されて高い意匠性が確保される。
【0039】
尚、以上の実施の形態では、止水材12を壁パネル1の凹部11a内に全幅に亘って貼り付けたが、図5に示すように、止水材12’を壁パネル1の凹部11a内に部分的貼り付けて凹凸嵌合部内に毛細管現象をカットするための大きな空間S’を確保するようにしても良い。
【0040】
【発明の効果】
以上の説明で明らかなように、本発明によれば、上下端面の一方に凸部を他方に凹部を形成して成る複数の壁パネルを凹凸嵌合によって上下方向に積み重ねて結合する壁パネルの結合構造において、前記各壁パネルに形成された凸部の頂部に段部を形成し、隣り合う壁パネルの凹凸嵌合部内に、毛細管現象をカットするための空間を形成したため、高い意匠性の確保と施工時間の短縮を図りつつ、毛細管現象による水の浸入を防いで高い止水性を確保することができるという効果が得られる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a connection structure of a wall panel applied to the construction of a wall surface of a unit bath, and more specifically, a plurality of wall panels formed by forming a convex portion on one of upper and lower end surfaces and a concave portion on the other. The present invention relates to a wall panel connecting structure that is vertically stacked and connected by fitting.
[0002]
[Prior art]
For example, as a mode of constructing the wall surface of the unit bus, a method of connecting a plurality of vertically long wall panels 101 in the left-right direction has been adopted as shown in FIG. In this method, as shown in FIG. 7, adjacent wall panels 101 are joined to each other as shown in FIG. 8 by using joint parts 113 and 114 attached to the back surface or the front end of the wall panel 101. 7 is a partial cross-sectional view (cross-sectional view taken along the line BB of FIG. 6) of the wall panel 101 before the connection and FIG. 8 after the connection.
[0003]
However, in the above method, a step Δt occurs on the surface of the wall panel 101 due to the thickness tolerance of the wall panel 101 as shown in FIG. 8A, or the mounting of the joint parts 113 and 114 as shown in FIG. There is a problem that a step Δa occurs on the surface of the wall panel 101 due to the tolerance.
[0004]
Also, since the joint parts 113 and 114 are partially fitted in the height direction of the wall panel 101, when the wall panel 101 is warped, the surface of the wall panel 101 is not provided where the joint parts 113 and 114 are not provided. Had a step.
[0005]
Further, there is a problem that the design is poor because the width of the joint between the wall panels 101 is wide.
[0006]
Further, as shown in FIG. 8, the joint between the wall panels 101 is subjected to a water stopping process with a caulking material 115 or a joint material, but the caulking material 115 which is a design different from the panel design is provided on the apparent surface. In addition to the fact that the design property is impaired due to the presence of the coking material 115 and the need for waterproofing treatment with the joint material, work such as application of the caulking material 115 and fitting of the joint material is required, and the construction time is prolonged. was there.
[0007]
Therefore, as shown in FIG. 9, a method has been proposed in which a plurality of wall panels 201 each having a convex portion 210a formed on one of the upper and lower end surfaces and a concave portion 211a formed on the other are vertically stacked by uneven fitting and joined. (See, for example, JP-A-10-311111 and JP-A-6-42075).
[0008]
[Problems to be solved by the invention]
However, in the wall panel coupling structure according to the above proposal, water infiltrates from the gap between the concave and convex fitting portions of the adjacent wall panels 201 due to capillary action, so that the water stoppage is poor, and water leakage to the outside of the wall panel 201 occurs. There was a problem.
[0009]
The present invention has been made in view of the above problems, and a purpose thereof is to secure high designability and shorten construction time, and to prevent water from entering by capillary action to ensure high water stopping performance. It is an object of the present invention to provide a joint structure of a wall panel that can be used.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, an invention according to claim 1 is directed to a wall panel in which a plurality of wall panels each having a convex portion formed on one of the upper and lower end surfaces and a concave portion formed on the other are vertically stacked and connected by uneven fitting. In the coupling structure, a step is formed at the top of the protrusion formed on each of the wall panels, and a space for cutting a capillary phenomenon is formed in the concave and convex fitting portion of the adjacent wall panel. .
[0011]
Therefore, according to the first aspect of the present invention, since the capillary phenomenon is cut by the space formed in the concavo-convex fitting portion of the adjacent wall panel, high waterproofness is secured in the concavo-convex fitting portion of the wall panel, Water leakage to the outside of the wall panel is reliably prevented. Therefore, a water stopping process using a caulking material or a joint material is not required, and the construction time can be reduced. In addition, the caulking material or the joint material does not exist in the joint portion of the wall panel, and the wall is further fitted by uneven fitting. Since there is no step on the panel, the appearance is beautiful and a high design property is secured.
[0012]
In addition, since a plurality of wall panels are vertically stacked and joined by the concave-convex fitting, the joint width between the wall panels is suppressed to be small, and the cleaning property is improved, and mold is generated because the joint part is not caulked. Can be suppressed.
[0013]
Furthermore, even if the wall panel has a warp, the warp is corrected by the concave and convex fitting, so that a step between the wall panels is eliminated, and a high design property is secured.
[0014]
The invention according to claim 2 is characterized in that, in the invention according to claim 1, a convex portion is formed on an upper end surface of each of the wall panels, and a concave portion is formed on a lower end surface.
[0015]
Therefore, according to the second aspect of the present invention, the water stopping effect at the uneven fitting portion of the wall panel is further enhanced.
[0016]
According to a third aspect of the present invention, in the first or the second aspect of the present invention, the convex portion and the concave portion are formed with reference to a surface of the wall panel.
[0017]
Therefore, according to the third aspect of the present invention, since the convex portion and the concave portion are formed with reference to the surface of the wall panel, the step between the adjacent wall panels is eliminated regardless of the thickness tolerance of the wall panel and the like. High designability is secured.
[0018]
According to a fourth aspect of the present invention, in the first aspect of the present invention, the height of the convex portion formed on each of the wall panels is set smaller than the depth of the concave portion.
[0019]
Therefore, according to the invention as set forth in claim 4, since the adjacent wall panels are closely attached in the up-down direction, the joint width between the two is minimized, and high designability, high waterproofness and cleanability are secured. .
[0020]
According to a fifth aspect of the present invention, in the fourth aspect of the present invention, a water blocking material is interposed between the concave portion and the convex portion of the concave and convex fitting portion of the adjacent wall panel.
[0021]
Therefore, according to the fifth aspect of the present invention, a secondary water stopping effect by the water stopping material is added to the water stopping effect by the cut of the capillary phenomenon by the space formed in the uneven fitting portion of the wall panel. In addition, water intrusion is more reliably prevented.
[0022]

The projection 10a projects from the upper end surface of the lower wall panel 1A that has already been connected, and the wall panel 1B is stacked on the wall panel 1A and connected. At this time, as shown in FIG. 3, a waterproof material 12 made of an elastic material is fitted over the entire width into a concave portion 11a formed on the lower end surface of the wall panel 1B and is attached. In this embodiment, a rubber-based packing having a thickness of 10 mm is used as the water-stopping material 12.
[0033]
As described above, when the waterproof material 12 is attached to the concave portion 11a of the wall panel 1B to be joined, as shown in FIG. 4, the concave portion 11a of the wall panel 1B to be joined is changed to the convex portion 10a of the lower wall panel 1A. Is fitted from above, the wall panel 1B is stacked and joined on the lower wall panel 1A by the concave and convex fitting. Then, the water-stopping material 12 is compressed and deformed by the convex portion 10a of the wall panel 1A, and fills the space with the convex portion 10a of the wall panel 1A in the concave portion 11a of the wall panel 1B over the entire width to provide a water-stopping function. Fulfill. Further, since the step 10b is formed at the top of the projection 10a of the wall panel 1A, a space S for cutting the capillary phenomenon is formed in the recess 11a over the entire length in the length direction (lateral direction).
[0034]
By the way, as described above, the height h (= 10 mm) of the convex portion 10a is set smaller than the depth d (= 15 mm) of the concave portion 11a, and the end surfaces a, which sandwich the concave portion 11a on the lower end surface of the wall panel 1B. Since a step of Δh (= 0.2 mm) is formed between b, the lower end surface of the wall panel 1B and the upper end surface of the wall panel 1A are in close contact with each other on the front side (the bathroom side), and are on the back side. In this case, a play corresponding to the step Δh occurs. As a result, the joint width between the joined wall panels 1A and 1B is minimized, high water stopping performance and cleanability are secured, and the water stopping process using a caulking material or a joint material is not required. , Construction time is reduced. In addition, since there is no caulking material or joint material at the joint portions of the wall panels 1A and 1B, generation of mold is suppressed.
[0035]
Further, as described above, since the width B of the concave portion 11a in each wall panel 1 is set to be slightly larger (about 0.1 to 0.3 mm) than the width b of the convex portion 10a, the concave portion of the wall panel 1B is formed. The projection 11a of the wall panel 1A is easily fitted to the projection 10a, and a play Δb (= 0.1 to 0.3 mm) shown in FIG. 4 is generated between the recess 11a and the projection 10a after the fitting. .
[0036]
By repeating the operation of stacking and joining a plurality of wall panels 1 in the vertical direction by uneven fitting in the same manner as described above, the side wall of the unit bathroom shown in FIG. 1 is constructed. Capillary phenomena are cut by the spaces S formed in the concave and convex fitting portions of the upper and lower wall panels 1, so that high waterproofness is secured in the concave and convex fitting portions of the wall panel 1, and water leakage to the outside of the wall panel 1 is ensured. Is prevented. Further, since the convex portion 10a is formed on the upper end surface of each wall panel 1 and the concave portion 11a is formed on the lower end surface, the water stopping effect at the concave and convex fitting portion of the wall panel 1 is further enhanced.
[0037]
Furthermore, since the water blocking material 12 is interposed between the concave portion 11a and the convex portion 10a of the uneven fitting portion of the upper and lower wall panels 1, the capillary phenomenon due to the space S formed in the uneven fitting portion of the wall panel 1 is prevented. A secondary water stopping effect by the water stopping material 12 is added to the water stopping effect by the cut, whereby the infiltration of water is more reliably prevented.
[0038]
Further, in each of the wall panels 1, as described above, the projections 10a and the depressions 11a are formed with reference to the surface, so that the steps of the upper and lower wall panels 1 are eliminated irrespective of the thickness tolerance of the wall panel 1, and the like. Even if the wall panel 1 has a warp, the warp is corrected by the concave and convex fitting, so that a step between the wall panels 1 is eliminated, and a high design property is secured.
[0039]
In the above embodiment, the water-stopping material 12 is stuck over the entire width of the recess 11a of the wall panel 1, but the water-stopping material 12 'is attached to the recess 11a of the wall panel 1 as shown in FIG. A large space S ′ for cutting the capillary phenomenon in the concave-convex fitting portion may be secured by partially attaching the inside.
[0040]
【The invention's effect】
As is apparent from the above description, according to the present invention, a plurality of wall panels each having a convex portion formed on one of the upper and lower end surfaces and a concave portion formed on the other are vertically stacked by concave-convex fitting and joined. In the joint structure, a step is formed at the top of the protrusion formed on each of the wall panels, and a space for cutting the capillary phenomenon is formed in the concave and convex fitting portion of the adjacent wall panel, so that a high design property is obtained. An effect is obtained in that it is possible to secure high water stoppage by preventing water from entering by capillary action while securing and shortening the construction time.
