Description

【0001】
【発明の属する技術分野】
本発明は、外壁本体の一部に開口部が設けられ、前記外壁本体の表面に胴縁が取り付けられる外壁構造に関する。
【0002】
【背景の技術】
近年、建物の構築についてはその工業化が進み、例えば壁や床、屋根といった構成要素を予め工場にてパネル化しておき、施工現場でこれらのパネルを組み立てることにより、建物を構築するといったパネル工法が一部に採用されている。このようなパネル工法に用いられる外壁パネルとして、例えば、図3に示すようなパネルが知られている。
【0003】
図3に示す外壁パネル100は、縦框材101,101と横框材102,102とが矩形枠状に組み立てられるとともに、この矩形枠の内部に補強芯材103…が縦横に組まれて枠体104が形成され、枠体104の一方の面に合板等の面材105が貼設されたものである。
そして、複数の外壁パネル100の側端面部どうしを連結させることにより、建物の外壁が構築されるようになっている。
また、この外壁パネルには、外側の面に防水シートが張設され、その上から胴縁が取り付けられる。
【0004】
前記胴縁は、例えば、特開平9−111896号公報に示すような、横方向に所定の間隔で取り付ける縦胴縁と、或いは、例えば、特開平7−158181号公報に示すような、縦方向に所定の間隔で取り付ける横胴縁と、がある。
縦胴縁は上下方向に空間が設けられているので、横胴縁に比べて通気性に優れるという特徴を有する。
【0005】
【発明が解決しようとする課題】
しかしながら、例えば、図2に示すように、開口部を有する連結外壁パネルの開口部直上の壁パネル(小壁パネル)に胴縁を取り付けた場合、開口部内に水が入り込まないようにコーキング処理等により開口部付近の防水処理を行っていたが、特に、開口部直上では、水が溜まりやすく念入りな防水処理を行っていたので、その作業が煩雑であるという問題点があった。
【0006】
本発明は上記問題点を解決するために為されたものであって、開口部付近の防水性をより簡易な手段により高めることが出来る外壁構造を提供することを目的とする。
【0007】
【課題を解決するための手段】
上記課題を解決するため、
請求項1記載の発明は、例えば、図1、図2に示すように、外壁本体3(例えば、パネル本体)の一部に開口部5が設けられ、前記外壁本体3の表面に胴縁6…が取り付けられる外壁構造であって、
前記開口部5の直上の前記外壁本体3に、水平方向に傾斜した斜め胴縁74が、前記開口部5の両側縁線a、aを上方に延長した仮想線を横切るようにして設けられ
前記斜め胴縁74の傾斜方向下方の端部74a(例えば、右下端部)と、前記開口部5の側縁部5aとの間の外壁本体3に、前記側縁部5aと略平行に上下に長尺な縦胴縁71が設けられ、当該縦胴縁71は、上端71aの位置が前記斜め胴縁74の傾斜方向下方の端部74aと同一か或いはそれ以上高く、且つ下端71bの位置が前記開口部5の下縁部5bと同一か或いはそれ以上低くなっていることを特徴としている。
【0008】
請求項1記載の発明によれば、外壁本体3表面の水は、斜め胴縁74の上面の傾斜に沿って下方に流れるので開口部5付近に溜まることなく排出出来るとともに、斜め胴縁74は、開口部5の両側縁線a、aが上方に延長された仮想線K1を横切るように設けられているので、水が開口部5内に流入することがないこととなって、開口部5の防水性を容易に且つ確実に高めることが出来る。
即ち、従来の縦胴縁或いは横胴縁にしても、開口部の上部付近には水が溜まりやすく、そのためコーキング打ち等の防水処理を十分に行う必要があったが、この斜め胴縁74を用いれば、開口部5の上部付近に溜まることなく水を開口部5の外側に流すことが出来ることとなって、開口部5の防水性を高めることができて開口部5付近の防水処理をより簡略化しても従来以上の防水性を得ることが可能となる。
また、斜め胴縁74の傾斜方向下方の端部74aと開口部5の側縁部5aとの間の外壁本体3に、前記側縁部5aと略平行に、且つ上端71aの位置が前記斜め胴縁74の下端部74aと同一か或いはそれ以上高く、下端71bの位置が前記開口部5の下縁部5bと同一か或いはそれ以上低い縦胴縁71が設けられているので、斜め胴縁74の下端部74aから流れた水が開口部5の側縁部5aから開口部5内に回り込むことがないこととなって、より開口部5の防水性を高めることが出来る。
【0009】
ここで、外壁本体3は、在来工法によって構築されたものであってもよいし、或いはパネル工法によって構築されたものであってもよい。
【0010】
請求項2記載の発明は、請求項1記載の外壁構造において、
斜め胴縁74上方の外壁本体3の表面に、上下に長尺な縦胴縁6…が水平方向に所定の間隔で設けられていることを特徴としている。
【0011】
請求項2記載の発明によれば、斜め胴縁74上方の外壁本体3の表面に水平方向に所定の間隔で上下に長尺な縦胴縁6…が設けられているので、特に、請求項1記載の効果をより顕著に得ることが出来る。
即ち、縦胴縁6…の場合には胴縁と胴縁との間に上下方向に長い空間が形成されるので、下方に水が溜まりやすいが、斜め胴縁74によって水を溜めることなく開口部5の側方からさらに下方に流入させることができることとなって、開口部5の防水性を高めることが出来る。
【0014】
請求項記載の発明は、請求項1又は2記載の外壁構造において、
外壁本体3の表面に、防水シート4が張設され、その上から前記斜め胴縁74が前記外壁本体3に取り付けられていることを特徴としている。
【0015】
請求項記載の発明によれば、請求項1又は2記載の発明と同様の効果が得られることは無論のこと、特に、外壁本体3の表面に、防水シート4が張設され、その上から斜め胴縁74が外壁本体3に取り付けられているので、外壁全体としての防水性能が更に高まる。
【0016】
ここで、外壁本体3への防水シート4の張設は、工場で行ってもよいし、或いは現場で行ってもよい。
防水シート4は、防水性を有するものであればどのようなものでもよいが、防水性と同時に透湿性を有するものであってもよい。
【0017】
請求項記載の発明は、請求項1〜3の何れかに記載の外壁構造において、
外壁本体3は複数のパネル2a、2b、2cが連結してなる連結パネルであることを特徴としている。
【0018】
請求項記載の発明によれば、外壁本体3は複数のパネル2a、2b、2cが連結してなる連結パネルにより構成されているので、このパネル2a、2b、2cを現場で連結させたり、或いは工場等で予め連結したものを現場で立設することが出来て、在来工法に比べて外壁構築を容易にすることが出来る。
【0019】
【発明の実施の形態】
以下、図を参照して本発明に係る外壁構造および外壁への胴縁取付方法の実施の形態について詳細に説明する。
図1は、本発明に係る外壁構造を示す外壁要部の正面図であり、図2は、同斜視図である。
図1〜3に示す本発明に係る外壁1は、いわゆるパネル工法によって構築されるものであって、外壁パネル2の端面部どうしが連結されてパネル本体3(外壁本体)が形成されている。
即ち、前記外壁1は、2つの側壁パネル2a、2aと、この側壁パネル2a、2aの上方の側端面部と、下方の側端面部どうしに接合された小壁パネル2bと腰壁パネル2cとからなるロ字状のパネル本体3(図2)と、該パネル本体3の一方の面に張設された防水シート4を備えている。そして、このパネル本体3の中央部には、開口部5が設けられている。
【0020】
側壁パネル2a、2aと小壁パネル2bおよび腰壁パネル2cは、例えば、縦框材21、21と横框材22、22とが矩形状に組み立てられるとともに、この矩形枠の内部に補強芯材(図示省略)が縦横に組まれて枠体が形成され、枠体の一方の面に合板等の面材23、23が貼設されたものである。
側壁パネル2a、2a、小壁パネル2bおよび腰壁パネル2cどうしの接合は、図示はしないが、接着剤、締結用のボルト、或いは釘打ちによってなされる。このように、パネル本体3は複数のパネル2a、2b、2cが連結してなる連結パネルにより構成されているので、このパネル2a、2b、2cから構築されているので、在来工法に比べて外壁構築を容易にすることが出来る。
【0021】
前記防水シート4は、例えば、ステープル打ち或いは接着剤によって外壁パネル2に張設されている。
防水シート4は、防水性および透湿性のシートであり、例えば、タイベック(商品名:デュポン社製)などを使用する。
また、防水シート4の上からは、パネル本体3の横方向にそって所定の間隔で縦胴縁6…がパネル本体3に取り付けられている。
【0022】
また、前記開口部5の周囲には、該開口部側縁部5aに縦胴縁71、72が、下縁部5bには横胴縁73が、上縁部5cには斜め胴縁74がそれぞれ設けられている。
前記縦胴縁71は、開口部5の側縁部5aと略平行となっているとともに、上端71aの位置が前記斜め胴縁74の右下端部74aより高く、且つ下端71bの位置が開口部5の下縁部5bよりも低くなっている。
前記斜め胴縁74は、開口部5と縦胴縁6の間の小壁パネル2bに右下がりに傾斜して取り付けられている。
【0023】
前記斜め胴縁74は、開口部5の両側縁部(側縁線)a、aを上方に延長した仮想線(破線で示す)を横切る長さを有し、右下端部74aが縦胴縁71の上端71aよりも下に位置している。
従って、斜め胴縁74の上方から小壁パネル2bを伝って流れてきた水は、斜め胴縁74の上面の傾斜にそって右下端部74a方向に流れ、更に側壁パネル2a下方に流れるようになっているので、水が開口部5の側縁部5aから開口部5内に回り込むことがないこととなって、より開口部5の防水性を高めることが出来るようになっている。
【0024】
また、斜め胴縁74は、小壁パネル2bにコーキング材が塗布された上から取り付けられ、これによって小壁パネル2bとの間のすき間が埋められている。
なお、斜め胴縁74の上面は、水が流れやすいように溝状にしてもよい。また、この斜め胴縁74には水が集まりやすいので、防水性を有する材料或いは防水処理されたもの(例えば、防水シートで覆ったもの)を使用するとより好ましい。
【0025】
続いて、上記パネル本体3への胴縁取付方法について説明する。
まず、パネル本体3の一方の面に防水シート4を張設し、次いで、パネル本体3の横方向にそって所定の間隔で防水シート4の上から縦胴縁6…を取り付ける。この防水シート4を張設することによって、外壁全体としての防水性能が更に高まる。
次いで、コーキング材をパネル本体3の上に塗布する。
そして、このコーキング材が塗布されたパネル本体3の上から、開口部5の両側縁線a、aを上方に延長した仮想線(破線で示す)を横切るとともに、右下端部74aの位置が縦胴縁71の上端71aより低くなるように、斜め胴縁74を取り付ける。
【0026】
以上説明した本発明に係る外壁(外壁構造)によれば、パネル本体3表面の水は、斜め胴縁74の上面の傾斜に沿って下方に流れるので、開口部5付近に溜まることなく水を開口部5の外側に排出出来るとともに、斜め胴縁74が開口部5の幅より長くなっているので水が開口部5内に流入されることがないこととなって、開口部5付近の防水性を容易に且つ確実に高めることが出来る。
即ち、従来の縦胴縁6…の場合、胴縁間に上下方向に長い空間が形成されるので、パネル本体3の表面を伝って開口部5の上部付近に水が溜まりやすく、そのためコーキング施工或いは防水シート4の張設等の防水処理を十分に行う必要があったが、この斜め胴縁74を用いれば、水は開口部5の上部付近に溜まることなく開口部5の外側に流すことが出来ることとなって、開口部5の防水性を高めることができて開口部5付近の防水処理の簡略化も可能となる。
【0027】
なお、斜め胴縁74と小壁パネル2bとの間のすき間は、防水シートを斜め胴縁の上から被せるようにすることによって遮断してもよい。
また、斜め胴縁の傾斜角度は、設計事項であり、任意に決めてよい。
【0028】
【発明の効果】
請求項1記載の発明によれば、外壁本体表面の水は、斜め胴縁の上面の傾斜に沿って下方に流れるので開口部付近に溜まることなく排出出来るとともに、斜め胴縁は、開口部の両側縁線が上方に延長された仮想線を横切るように設けられているので、水が開口部内に流入することがないこととなって、開口部の防水性を容易に且つ確実に高めることが出来る。
また、斜め胴縁の傾斜方向下方の端部と開口部の側縁部との間の外壁本体に、前記側縁部と略平行に、且つ上端の位置が前記斜め胴縁の下端部と同一か或いはそれ以上高く、下端の位置が前記開口部の下端部と同一か或いはそれ以上低い縦胴縁が設けられているので、斜め胴縁の下端部から流れた水が開口部の側縁部から開口部内に回り込むことがないこととなって、より開口部の防水性を高めることが出来る。
【0029】
請求項2記載の発明によれば、斜め胴縁上方の外壁本体の表面に所定の間隔で縦胴縁が設けられているので、特に、請求項1記載の効果をより顕著に得ることが出来る。
【0031】
請求項記載の発明によれば、請求項1又は2記載の発明と同様の効果が得られることは無論のこと、特に、外壁本体の表面に、防水シートが張設され、その上から斜め胴縁が外壁本体に取り付けられているので、外壁全体としての防水性能が更に高まる。
【0032】
請求項記載の発明によれば、外壁本体は複数のパネルが連結してなる連結パネルにより構成されているので、このパネルを現場で連結させたり、或いは工場等で予め連結したものを現場で立設することが出来て、在来工法に比べて外壁構築を容易にすることが出来る。

[0002]
[Background technology]
In recent years, the construction of buildings has been industrialized. For example, there is a panel construction method in which components such as walls, floors, and roofs are panelized in the factory in advance, and these panels are assembled at the construction site to construct the building. Adopted in some areas. As an outer wall panel used in such a panel construction method, for example, a panel as shown in FIG. 3 is known.
[0003]
3 has a vertical frame member 101, 101 and a horizontal frame member 102, 102 assembled in a rectangular frame shape, and a reinforcing core member 103 is assembled vertically and horizontally inside the rectangular frame. A body 104 is formed, and a face material 105 such as plywood is attached to one surface of the frame body 104.
And the outer wall of a building is constructed | assembled by connecting the side end surface parts of the some outer wall panel 100. FIG.
In addition, a waterproof sheet is stretched on the outer surface of the outer wall panel, and a trunk edge is attached thereto.
[0004]
The trunk edge is, for example, as shown in Japanese Patent Application Laid-Open No. 9-111896, with a vertical body edge attached at a predetermined interval in the horizontal direction, or, for example, as shown in Japanese Patent Application Laid-Open No. 7-158181, in the vertical direction. And a horizontal torso edge attached at a predetermined interval.
Since the vertical trunk edge is provided with a space in the vertical direction, the vertical trunk edge has a feature of excellent air permeability as compared with the horizontal trunk edge.
[0005]
[Problems to be solved by the invention]
However, for example, as shown in FIG. 2, when a trunk edge is attached to a wall panel (small wall panel) immediately above the opening of the connecting outer wall panel having an opening, a caulking process or the like is performed so that water does not enter the opening. However, there was a problem that the work was complicated because water was easily collected in the vicinity of the opening so that water was easily collected.
[0006]
The present invention has been made to solve the above-described problems, and an object of the present invention is to provide an outer wall structure capable of enhancing the waterproofness in the vicinity of the opening by simpler means.
[0007]
[Means for Solving the Problems]
To solve the above problem,
In the first aspect of the present invention, for example, as shown in FIGS. 1 and 2, an opening 5 is provided in a part of an outer wall main body 3 (for example, a panel main body), and a trunk edge 6 is formed on the surface of the outer wall main body 3. Is an outer wall structure to which ...
In the outer wall main body 3 immediately above the opening 5, an oblique trunk edge 74 inclined in the horizontal direction is provided so as to cross a virtual line extending upward on both side edge lines a, a of the opening 5 ,
In the outer wall main body 3 between the end 74a (for example, the lower right end) of the oblique trunk edge 74 in the inclination direction and the side edge 5a of the opening 5, the upper and lower sides are substantially parallel to the side edge 5a. Is provided with a long vertical drum edge 71, and the vertical drum edge 71 has a position of the upper end 71 a that is equal to or higher than the end 74 a of the slanted drum edge 74 in the inclination direction and a position of the lower edge 71 b. Is characterized by being equal to or lower than the lower edge 5b of the opening 5 .
[0008]
According to the first aspect of the present invention, the water on the surface of the outer wall main body 3 flows downward along the slope of the upper surface of the slanted trunk edge 74, so that it can be discharged without accumulating near the opening 5. Since both side edge lines a, a of the opening 5 are provided so as to cross the imaginary line K1 extended upward, water does not flow into the opening 5 and the opening 5 Can be easily and reliably improved.
That is, even with the conventional vertical or horizontal trunk edge, water tends to accumulate near the upper part of the opening, and therefore it was necessary to perform sufficient waterproofing treatment such as caulking. If used, water can flow outside the opening 5 without accumulating in the vicinity of the upper part of the opening 5, so that the waterproofness of the opening 5 can be improved and the waterproof treatment in the vicinity of the opening 5 can be performed. Even if it is further simplified, it is possible to obtain a waterproof property that is higher than conventional ones.
Further, the outer wall main body 3 between the lower end 74a of the oblique trunk edge 74 and the side edge 5a of the opening 5 is substantially parallel to the side edge 5a and the position of the upper end 71a is inclined. Since the vertical trunk edge 71 is provided which is equal to or higher than the lower end part 74a of the trunk edge 74 and whose lower end 71b is equal to or lower than the lower edge part 5b of the opening 5, the oblique trunk edge The water flowing from the lower end portion 74a of 74 does not enter the opening portion 5 from the side edge portion 5a of the opening portion 5, so that the waterproofness of the opening portion 5 can be further improved.
[0009]
Here, the outer wall main body 3 may be constructed by a conventional construction method, or may be constructed by a panel construction method.
[0010]
The invention according to claim 2 is the outer wall structure according to claim 1,
Longitudinal vertical trunk edges 6 are vertically provided at predetermined intervals in the horizontal direction on the surface of the outer wall main body 3 above the oblique trunk edge 74.
[0011]
According to the second aspect of the present invention, since the vertical wall edges 6 are vertically provided at predetermined intervals in the horizontal direction on the surface of the outer wall main body 3 above the oblique body edge 74, The effect described in 1 can be obtained more remarkably.
That is, in the case of the longitudinal trunk edges 6..., A long space is formed between the trunk edges in the vertical direction, so that water tends to collect downward, but the oblique trunk edges 74 open the water without collecting water. Since it can be made to flow further downward from the side of the part 5, the waterproofness of the opening part 5 can be improved.
[0014]
The invention according to claim 3 is the outer wall structure according to claim 1 or 2 ,
The waterproof sheet 4 is stretched on the surface of the outer wall main body 3, and the oblique trunk edge 74 is attached to the outer wall main body 3 from above .
[0015]
According to the invention described in claim 3, it is needless to say that the same effect as that of the invention described in claim 1 or 2 can be obtained. In particular, the waterproof sheet 4 is stretched on the surface of the outer wall body 3, Since the slanted trunk edge 74 is attached to the outer wall main body 3, the waterproof performance as the entire outer wall is further enhanced.
[0016]
Here, the stretching of the waterproof sheet 4 to the outer wall main body 3 may be performed at a factory or on site.
The waterproof sheet 4 may be anything as long as it has waterproofness, but may be waterproof and moisture permeable at the same time.
[0017]
The invention according to claim 4 is the outer wall structure according to any one of claims 1 to 3 ,
The outer wall body 3 is a connecting panel formed by connecting a plurality of panels 2a, 2b, and 2c.
[0018]
According to the invention of claim 4 , since the outer wall main body 3 is constituted by a connection panel formed by connecting a plurality of panels 2a, 2b, 2c, the panels 2a, 2b, 2c can be connected in the field, Or what was connected beforehand in a factory etc. can be erected on the spot, and an outer wall construction can be made easier compared with a conventional construction method.
[0019]
DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of an outer wall structure and a method for attaching a trunk edge to an outer wall according to the present invention will be described in detail with reference to the drawings.
FIG. 1 is a front view of a main part of an outer wall showing an outer wall structure according to the present invention, and FIG. 2 is a perspective view thereof.
The outer wall 1 according to the present invention shown in FIGS. 1 to 3 is constructed by a so-called panel method, and the end surface portions of the outer wall panel 2 are connected to form a panel body 3 (outer wall body).
That is, the outer wall 1 includes two side wall panels 2a and 2a, an upper side end surface portion of the side wall panels 2a and 2a, and a small wall panel 2b and a waist wall panel 2c joined to the lower side end surface portions. And a waterproof sheet 4 stretched on one surface of the panel body 3. An opening 5 is provided at the center of the panel body 3.
[0020]
The side wall panels 2a and 2a, the small wall panel 2b, and the waist wall panel 2c are, for example, the vertical rib members 21 and 21 and the horizontal rib members 22 and 22 assembled in a rectangular shape, and a reinforcing core material inside the rectangular frame. (Not shown) is assembled vertically and horizontally to form a frame, and face materials 23 such as plywood are pasted on one surface of the frame.
The side walls 2a, 2a, the small wall panel 2b, and the waist wall panel 2c are joined by an adhesive, a fastening bolt, or a nail, although not shown. Thus, since the panel body 3 is constituted by a connection panel formed by connecting a plurality of panels 2a, 2b, and 2c, it is constructed from the panels 2a, 2b, and 2c, and therefore, compared to the conventional construction method. Construction of the outer wall can be facilitated.
[0021]
The waterproof sheet 4 is stretched on the outer wall panel 2 by, for example, stapling or an adhesive.
The waterproof sheet 4 is a waterproof and moisture-permeable sheet, and for example, Tyvek (trade name: manufactured by DuPont) is used.
Further, from the top of the waterproof sheet 4, vertical trunk edges 6 are attached to the panel body 3 at predetermined intervals along the horizontal direction of the panel body 3.
[0022]
Further, around the opening 5, there are vertical trunk edges 71 and 72 on the opening side edge 5a, a horizontal trunk edge 73 on the lower edge 5b, and an oblique trunk edge 74 on the upper edge 5c. Each is provided.
The vertical trunk edge 71 is substantially parallel to the side edge part 5a of the opening 5, the position of the upper end 71a is higher than the right lower end part 74a of the oblique trunk edge 74, and the position of the lower end 71b is the opening part. 5 is lower than the lower edge 5b.
The oblique trunk edge 74 is attached to the small wall panel 2b between the opening 5 and the vertical trunk edge 6 so as to be inclined downward to the right.
[0023]
The oblique trunk edge 74 has a length that crosses the imaginary line (shown by a broken line) extending upward from both side edges (side edge lines) a, a of the opening 5, and the right lower end 74 a is a vertical trunk edge. It is located below the upper end 71a of 71.
Accordingly, the water flowing along the small wall panel 2b from above the oblique trunk edge 74 flows in the direction of the right lower end 74a along the inclination of the upper surface of the oblique trunk edge 74, and further flows below the sidewall panel 2a. Therefore, water does not flow into the opening 5 from the side edge 5a of the opening 5, and the waterproofness of the opening 5 can be further improved.
[0024]
Further, the slanted trunk edge 74 is attached from the side where the caulking material is applied to the small wall panel 2b, thereby filling the gap between the small wall panel 2b and the small wall panel 2b.
The upper surface of the slanted trunk edge 74 may have a groove shape so that water can easily flow. Further, since water tends to collect on the slanted trunk edge 74, it is more preferable to use a waterproof material or a waterproof material (for example, a material covered with a waterproof sheet).
[0025]
Next, a method for attaching the trunk edge to the panel body 3 will be described.
First, the waterproof sheet 4 is stretched on one surface of the panel body 3, and then the vertical trunk edges 6 are attached from above the waterproof sheet 4 at predetermined intervals along the horizontal direction of the panel body 3. By stretching the waterproof sheet 4, the waterproof performance as the entire outer wall is further enhanced.
Next, a caulking material is applied on the panel body 3.
Then, from above the panel body 3 to which the caulking material is applied, it crosses a virtual line (shown by a broken line) extending upward from both side edges a, a of the opening 5, and the position of the right lower end 74a is vertical. The oblique trunk edge 74 is attached so as to be lower than the upper end 71 a of the trunk edge 71.
[0026]
According to the outer wall (outer wall structure) according to the present invention described above, the water on the surface of the panel body 3 flows downward along the inclination of the upper surface of the slanted trunk edge 74, so that the water is not collected in the vicinity of the opening 5. While being able to discharge to the outside of the opening 5, the slanted trunk edge 74 is longer than the width of the opening 5, so that water does not flow into the opening 5, so that the water around the opening 5 is waterproof. Can be easily and reliably improved.
That is, in the case of the conventional vertical body edge 6..., A long space is formed between the body edges in the vertical direction, so that water tends to accumulate near the upper part of the opening 5 along the surface of the panel body 3. Alternatively, it was necessary to sufficiently perform waterproofing processing such as stretching of the waterproof sheet 4, but if this oblique trunk edge 74 is used, water flows outside the opening 5 without collecting near the upper part of the opening 5. As a result, the waterproofness of the opening 5 can be improved, and the waterproofing treatment in the vicinity of the opening 5 can be simplified.
[0027]
In addition, you may interrupt | block the clearance gap between the slanting trunk edge 74 and the small wall panel 2b by making a waterproof sheet cover from a slanting trunk edge.
Further, the inclination angle of the oblique trunk edge is a design matter and may be arbitrarily determined.
[0028]
【The invention's effect】
According to the first aspect of the present invention, the water on the outer wall main body surface flows downward along the slope of the upper surface of the oblique trunk edge, so that it can be discharged without accumulating near the opening, and the oblique trunk edge Since both side edge lines are provided so as to cross the imaginary line extended upward, water will not flow into the opening, and the waterproofness of the opening can be easily and reliably increased. I can do it.
Further, the outer wall main body between the lower end of the oblique trunk edge in the inclination direction and the side edge of the opening is substantially parallel to the side edge, and the upper end position is the same as the lower end of the oblique trunk edge. Since the vertical trunk edge is higher or higher and the position of the lower end is the same as or lower than the lower end of the opening, water flowing from the lower end of the oblique trunk edge is provided on the side edge of the opening. Therefore, the waterproofness of the opening can be further improved.
[0029]
According to the second aspect of the present invention, since the vertical trunk edge is provided at a predetermined interval on the surface of the outer wall body above the oblique trunk edge, the effect of the first aspect can be obtained more remarkably. .
[0031]
According to the invention described in claim 3, it is needless to say that the same effect as that of the invention described in claim 1 or 2 can be obtained. In particular, a waterproof sheet is stretched on the surface of the outer wall main body, and obliquely inclined from above. Since the trunk edge is attached to the outer wall main body, the waterproof performance as the entire outer wall is further enhanced.
[0032]
According to invention of Claim 4 , since the outer wall main body is comprised by the connection panel formed by connecting a plurality of panels, this panel can be connected at the site, or what is connected in advance at the factory or the like at the site. It can be erected and the outer wall construction can be made easier compared to conventional construction methods.
