Description

【0001】
【発明の属する技術分野】
本発明は、ふかし壁部分の気密構造に関し、天井の気密ラインと壁の気密ラインをつなげるふかし壁部分の気密構造に関するものである。
【0002】
【従来の技術】
図6は、従来の間仕切壁と天井の接合部の気密構造20を示したものである。すなわち、図示するように、上面に気密シート26が一体となるように設けられた天井ボード7が、天井面に配置された天井野縁21の下面にビスなどの固定具によって固定された後、前記天井ボード7の下面及び床面に取付けられた断面コの字型の間仕切ランナー22によって間仕切スタッド23が固定され、該間仕切スタッド23及び前記間仕切ランナー22の両側面に間仕切ボード24がビスなどの固定具によって取付けられたものである。
【0003】
気密シート26は、四角形の天井ボード7よりも若干大きい面積を有し、且つ天井ボード7と相似形の四角形に形成されたものであり、一の角部を合わせて天井ボード7の上面に配置されることにより、前記一の角部の対角において隣接する天井ボード7の2辺の端縁から突出することとなり、突出部27が形成されている。したがって、天井ボード7が気密シート26の突出部27が同一方向に位置するように、そして、気密シート26の突出部27が隣接する他の天井ボード7の上面に設けられた気密シート26と重なるように天井野縁21の下面に固定することにより、天井ボード7の上面と天井野縁21の下面との間に気密面が構成され、屋内側と屋外側との間の気密性が確保されている。
【0004】
この天井ボード7の施工は、間仕切壁25の設置前に行われるため、間仕切壁25と接合していない一般部における気密面の形成と間仕切壁25の接合部分における気密面の形成が同時に行えるため、天井と間仕切壁25との接合部においても前記一般部と同じ気密構造を形成することができ、間仕切壁25を施工した後に気密シート26を取付ける場合に比べて、施工手順を簡易化して気密施工に要する作業工数を減少させると共に、施工ミスを減少させてより確実に気密性を確保することができる。

【発明が解決しようとする課題】
しかしながら、和室で内障子を設置するために、図7に示すように通常の下地材にふかし材を配設して該ふかし材に壁ボード5を貼設してふかし壁6を設けた場合、上記の天井ボード7の上面に配置された気密シート26により形成された気密面と壁面に沿って形成された気密面3とがふかし壁6内部で繋がっていないため、天井ボード7の上方の空気がふかし壁6内部に流入してしまい、壁ボード5に結露を生じてしまう等の問題点がある。
【0007】
本発明は、上記課題に鑑みてなされたものであって、本発明の目的は、ふかし壁内部に天井上方の空気が流入するのを防止してふかし壁部分における気密性を確保することである。
【0008】
【課題を解決するための手段】
上記目的を達成するために、請求項1記載のふかし壁部分の気密構造は、住宅の壁に沿って形成された気密面の屋内側にふかし材が列設され、該ふかし材に壁ボードを貼設してふかし壁が設けられたふかし壁部分の気密構造であって、前記壁ボードと天井ボードとが気密ジョイントにより接続され、前記ふかし材間に、天井ボードと略同高さとなるように、弾力性を有する気密部材が密嵌されたことを特徴としている。
【0009】
請求項2記載のふかし壁部分の気密構造は、請求項1に記載のふかし壁部分の気密構造において、前記気密部材の両端部は、中央部より易変形性であることを特徴としている。
【0010】
請求項3記載のふかし壁部分の気密構造は、請求項1又は2に記載のふかし壁部分の気密構造において、前記気密部材は、独立気泡の発泡合成樹脂からなるものであることを特徴としている。
【0011】
請求項4記載のふかし壁部分の気密構造は、請求項1乃至3に記載のふかし壁部分の気密構造において、前記気密ジョイントは、断面略L字型の長尺部材の内側面に弾性気密シートが貼設されたものであり、該弾性気密シートにより前記壁ボードと天井ボードとの接続部を密封するように前記ふかし材に固定されたものであることを特徴としている。
【0012】
【発明の実施の形態】
以下、本発明に係るふかし壁部分の気密構造について図面に基づき説明する。本発明の実施の形態に係るふかし壁部分の気密構造1は、図1及び図2に示すように、住宅の壁2に沿って形成された気密面3の屋内側にふかし材4が列設され、該ふかし材4に壁ボード5を貼設してふかし壁6が設けられており、該壁ボード5と天井ボード7とが気密ジョイント8により接続され、前記ふかし材4間に、天井ボード7と略同高さとなるように、弾力性を有する気密部材9が前記ふかし材4、気密面3、及び気密ジョイント8に密接するように嵌め込まれたものである。
【0013】
前記住宅の壁2に沿って形成された気密面3は、住宅の壁2の内側に所定の間隔で立設した下地材12の間に断熱材10を施工した後、図3に示すように、該断熱材10の室内側に防湿フィルム11を貼設することによって該防湿フィルム11に沿って形成されるものである。なお、本発明の実施の形態においては、気密面3は住宅の外壁に沿って形成されたものであるが、気密面3が形成される前記壁2は外壁に限定されるものではなく、断熱材10が施工されその全面を覆うように防湿フィルム11が貼設された壁であれば、間仕切壁等であってもよい。
【0014】
前記ふかし壁6は、図1及び図2に示すように、前記防湿フィルム11の屋内側にふかし材4が前記下地材12に沿って列設され、該ふかし材4に気密ジョイント8が天井ボード7を設置する高さと略同位置となるように固定され、壁ボード5が、上端部を気密ジョイント8に密接するようにしてふかし材4に固定されて構成されている。
【0015】
前記気密ジョイント8は、図4に示すように、その断面が略L字型である長尺部材であり、その内側面であって天井ボード7と当接する面に、弾性気密シート13が貼設されている。該弾性気密シート13は、気密ジョイント8と略同長さで、発泡合成樹脂からなるシート状の部材である。このように構成された気密ジョイント8が、図3に示すように天井ボード7の貼設位置に、前記弾性気密シート13が下方を向くようにふかし材4に固定され、該弾性気密シート13が、その後に天井野縁に固定される天井ボード7の端縁の上面及び壁ボード5の上端面と圧接して、天井ボード7と壁ボード5との接続部の気密を確保するものとなっている。
【0016】
前記気密部材9は、図5に示すように弾力性を有する略直方体形状の部材であり、中央部15とその両端部14とからなり、その幅Wはふかし材4間の距離よりも若干大きくなるように、そして、奥行Dは気密面3、すなわち防湿フィルム11から気密ジョイント8までの距離よりも若干大きくなるように構成されている。なお、気密部材9の高さHは該気密部材9を確実に配置することができ、所定の気密性を確保することができる高さであれば特に限定されるものではない。
【0017】
前記両端部14は、中央部よりも易変形性であり、具体的には中央部15よりも発泡率の高い発泡合成樹脂で形成されている。一方、その中央部15は、ふかし材4間に配設された際に略直方体形状を維持できる程度の硬さのものである。また、両端部14を易変形性とすることにより、ふかし材4間の寸法誤差を両端部14の変形で吸収できるので、現場で、ふかし材4間の寸法に合わせて加工する必要がなく、また、ふかし材4間に圧入することも容易となる。
【0018】
また、気密部材9は、例えば、発泡合成樹脂から作製することができる。この発泡合成樹脂は、連続気泡の発泡合成樹脂であっても一定の気密性を確保することはできるが、より高い気密性を確保するためには、気密部材9は独立気泡の発泡合成樹脂で形成することが好ましい。このように構成された気密部材9が、ふかし材4、気密ジョイント8、及び防湿フィルム11間の空間に圧縮されるようにして配置され、ふかし材4、気密ジョイント8、及び防湿フィルム11と密接して、該空間の気密性を確保するようになっている。
【0019】
前記天井ボード7は、天井野縁の下面にビスなどの固定具によって天井全面に隙間なく固定される。該天井ボード7は、天井下地を構成する板状の部材であり、気密性を有する部材で形成するとが好適であるが、その上面に気密シートを貼設して、天井面の気密を確保してもよい。これにより、天井ボード7に沿って気密面が形成される。また、壁ボード5と接する部分に固定される天井ボード7は、図1に示したように、その端縁の上面が気密ジョイント8の弾性気密シート13と圧接し、壁ボード5と接続されている。
【0020】
以上説明したように、壁2の下地材12間に施工された断熱材10の屋内側に貼設された防湿シート11によって形成された気密面3と、ふかし材4に固定された気密ジョイント8との間には気密部材9が密接に嵌め込まれており、また、天井ボード7とふかし壁6の壁ボード5とは気密ジョイント8によって気密性が確保されている。したがって、壁2に沿って形成された気密面3と天井ボード7によって形成された天井の気密面がつながっているため、天井上方の空気がふかし壁6内に流入するのを防止してふかし壁6部分における気密性を確保することができる。なお、本発明の実施の形態においては、気密部材9はふかし材4に壁ボード5を貼設した後にふかし材4間に配置するものとしたが、壁ボード5を貼設する前に配置してもよく、この場合、気密部材9を嵌め込むふかし材4間の空隙の上方と下方が開口しているため、気密部材9をより容易に嵌め込むことができる。
【0021】
【発明の効果】
請求項1記載のふかし壁部分の気密構造は、ふかし壁内のふかし材間に天井ボードと略同高さとなるように気密部材が密嵌されているので、壁に沿って構成された気密面と天井面に沿って構成された気密面とがつながり、天井上方の空気がふかし壁内部に流入するのを防いでふかし壁部分の気密性を確保することができる。また、気密部材は、弾力性を有しているため、ふかし材間に密接するように容易に嵌め込むことができ、ふかし材間及び気密ジョイントと気密面の間に隙間ができるのを防止して確実に気密性を確保することができる。
【0022】
請求項2記載のふかし壁部分の気密構造は、気密部材の両端部が中央部より易変形性であるため、ふかし材間の寸法に多少の誤差があっても配置することが可能であり、木材等のように現場で加工を行う必要がないため、気密施工にかかる時間を短縮することができる。
【0023】
請求項3記載のふかし壁部分の気密構造は、気密部材が独立気泡の発泡合成樹脂からなるものであるので、連続気泡の発泡合成樹脂からなる気密部材に比べ、より高い気密性を確保することができる。
【0024】
請求項4記載のふかし壁部分の気密構造は、気密ジョイントが断面略L字型の長尺部材の内側面に弾性気密シートが貼設されたものであるため、壁ボードと天井ボードとの接続部が密封されて、壁ボードと天井ボードの間の気密性が気密ジョイントにより確保される。したがって、ふかし材間に、気密ジョイント及び気密面に密接するように気密部材を配置することで、ふかし壁部分の気密性を容易に確保することができる。

[0012]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an airtight structure of a soft wall portion according to the present invention will be described with reference to the drawings. As shown in FIG. 1 and FIG. 2, the airtight structure 1 of the fussy wall portion according to the embodiment of the present invention has the fusible material 4 arranged on the indoor side of the airtight surface 3 formed along the wall 2 of the house. A wall board 5 is affixed to the plastering material 4 to provide a plastering wall 6, and the wall board 5 and the ceiling board 7 are connected by an airtight joint 8. 7, an airtight member 9 having elasticity is fitted so as to be in close contact with the softening material 4, the airtight surface 3, and the airtight joint 8.
[0013]
As shown in FIG. 3, the airtight surface 3 formed along the wall 2 of the house is constructed by installing a heat insulating material 10 between the base materials 12 erected at a predetermined interval inside the wall 2 of the house. The moisture-proof film 11 is formed on the indoor side of the heat insulating material 10 so as to be formed along the moisture-proof film 11. In the embodiment of the present invention, the airtight surface 3 is formed along the outer wall of the house. However, the wall 2 on which the airtight surface 3 is formed is not limited to the outer wall, and is insulated. A partition wall or the like may be used as long as the material 10 is applied and the moisture-proof film 11 is attached so as to cover the entire surface.
[0014]
As shown in FIG. 1 and FIG. 2, the softening wall 6 has a softening material 4 arranged on the indoor side of the moisture-proof film 11 along the base material 12, and an airtight joint 8 is connected to the softening material 4 on the ceiling board. The wall board 5 is fixed to the wiping material 4 so that the upper end of the wall board 5 is in close contact with the airtight joint 8.
[0015]
As shown in FIG. 4, the airtight joint 8 is a long member having a substantially L-shaped cross section, and an elastic airtight sheet 13 is affixed to the inner surface of the airtight joint 8 that contacts the ceiling board 7. Has been. The elastic hermetic sheet 13 is a sheet-like member that is substantially the same length as the hermetic joint 8 and is made of foamed synthetic resin. As shown in FIG. 3, the airtight joint 8 configured in this way is fixed to the covering material 4 so that the elastic airtight sheet 13 faces downward at the position where the ceiling board 7 is attached. Thereafter, the upper surface of the edge of the ceiling board 7 fixed to the ceiling edge and the upper end surface of the wall board 5 are pressed into contact with each other to ensure the airtightness of the connection portion between the ceiling board 7 and the wall board 5. Yes.
[0016]
The airtight member 9 is a substantially rectangular parallelepiped member having elasticity as shown in FIG. 5, and is composed of a central portion 15 and both end portions 14 thereof, and the width W thereof is slightly larger than the distance between the filler materials 4. The depth D is configured to be slightly larger than the distance from the airtight surface 3, that is, the moisture-proof film 11 to the airtight joint 8. Note that the height H of the airtight member 9 is not particularly limited as long as the airtight member 9 can be reliably disposed and a predetermined airtightness can be secured.
[0017]
The both end portions 14 are more easily deformable than the central portion, and specifically are formed of a foamed synthetic resin having a higher foaming rate than the central portion 15. On the other hand, the central portion 15 has a hardness that can maintain a substantially rectangular parallelepiped shape when disposed between the filler materials 4. In addition, by making the both end portions 14 easily deformable, the dimensional error between the filler materials 4 can be absorbed by the deformation of the both end portions 14, so there is no need to process in accordance with the dimensions between the filler materials 4 on site, Moreover, it becomes easy to press-fit between the filler materials 4.
[0018]
Moreover, the airtight member 9 can be made of, for example, a foamed synthetic resin. Although this foamed synthetic resin can ensure a certain airtightness even if it is an open-celled foamed synthetic resin, in order to ensure higher airtightness, the airtight member 9 is made of a closed-celled foamed synthetic resin. It is preferable to form. The airtight member 9 configured in this manner is disposed so as to be compressed in the space between the filler material 4, the airtight joint 8, and the moisture-proof film 11, and is in close contact with the filler material 4, the airtight joint 8, and the moisture-proof film 11. Thus, the airtightness of the space is ensured.
[0019]
The ceiling board 7 is fixed to the entire surface of the ceiling without a gap by a fixture such as a screw on the lower surface of the ceiling edge. The ceiling board 7 is a plate-like member that constitutes the ceiling base, and is preferably formed of an airtight member. However, an airtight sheet is attached to the upper surface of the ceiling board 7 to ensure the airtightness of the ceiling surface. May be. Thereby, an airtight surface is formed along the ceiling board 7. Further, as shown in FIG. 1, the ceiling board 7 fixed to the portion in contact with the wall board 5 is connected to the wall board 5 by pressing the upper surface of the edge with the elastic airtight sheet 13 of the airtight joint 8. Yes.
[0020]
As described above, the airtight surface 3 formed by the moisture-proof sheet 11 affixed on the indoor side of the heat insulating material 10 constructed between the base materials 12 of the wall 2 and the airtight joint 8 fixed to the covering material 4. An airtight member 9 is closely fitted between the ceiling board 7 and the wall board 5 of the cover wall 6 by the airtight joint 8 to ensure airtightness. Therefore, since the airtight surface 3 formed along the wall 2 and the airtight surface of the ceiling formed by the ceiling board 7 are connected to each other, the air above the ceiling is prevented from flowing into the soft wall 6 and the soft wall. Airtightness in the 6 parts can be ensured. In the embodiment of the present invention, the airtight member 9 is arranged between the plastering materials 4 after the wallboard 5 is pasted on the plastering material 4, but it is disposed before the wallboard 5 is pasted. In this case, since the upper and lower sides of the gap between the softening members 4 into which the airtight member 9 is fitted are opened, the airtight member 9 can be fitted more easily.
[0021]
【The invention's effect】

And an airtight surface configured along the ceiling surface are connected, and air above the ceiling is prevented from flowing into the interior of the wall, and the airtightness of the wall portion can be ensured. In addition, since the airtight member has elasticity, it can be easily fitted so as to be in close contact with the filler material, and a gap is prevented between the filler material and between the airtight joint and the airtight surface. It is possible to ensure airtightness reliably.
[0022]
The airtight structure of the softening wall portion according to claim 2 can be arranged even if there is some error in the dimension between the softening materials because both end portions of the airtight member are more easily deformable than the central portion. Since it is not necessary to perform on-site processing like wood, time required for airtight construction can be shortened.
[0023]
In the airtight structure of the soft wall portion according to claim 3, since the airtight member is made of a closed-cell foamed synthetic resin, higher airtightness is ensured than an airtight member made of an open-celled foam synthetic resin. Can do.
[0024]
In the airtight structure of the soft wall portion according to claim 4, the airtight joint is formed by attaching an elastic airtight sheet to the inner side surface of the long member having a substantially L-shaped cross section. The part is sealed, and the airtightness between the wall board and the ceiling board is ensured by the airtight joint. Therefore, by arranging the airtight member so as to be in close contact with the airtight joint and the airtight surface between the filler materials, the airtightness of the filler wall portion can be easily ensured.
