Description

本発明は、外壁躯体に形成された開口部にサッシ枠が設けられた外壁開口部構造に関する。   The present invention relates to an outer wall opening structure in which a sash frame is provided in an opening formed in an outer wall housing.

建物の外壁躯体に形成された開口部に、前記外壁躯体の表面より奥側にサッシ枠が取り付けられた外壁開口部構造の一例として特許文献１に記載の技術が知られている。
この技術では、建物の外壁は、外壁躯体としての壁パネルと、この壁パネルの室外面に設けられた外壁仕上げ材としての外装材と、壁パネルの室内面に設けられた内部仕上げ材としての石膏ボード等の内装材とを有して構成されている。
壁パネルは、格子状等に組んだパネル芯材と、このパネル芯材の室外側に固定されたパネル面材とで形成されている。また、外装材は、壁パネルの室外面にモルタルを所定厚さに吹きつけて形成されている。
この外壁には、矩形状の開口部が設けられており、縦辷り出し窓は、開口部内における外壁の室外面よりも見込み方向室内寄りに設けられた、いわゆる内付けサッシ窓である。
また、前記特許文献１では、外装材をモルタルに代えて、サイディング等のパネル材による乾式工法で構成した例が記載されている。パネル材には室内側に折れ曲がった折曲部が形成されている。
特開２００６−８３６６０号公報 As an example of an outer wall opening structure in which a sash frame is attached to an opening formed in an outer wall housing of a building on the back side from the surface of the outer wall housing, a technique described in Patent Document 1 is known.
In this technology, the outer wall of a building is a wall panel as an outer wall frame, an exterior material as an outer wall finishing material provided on the outdoor surface of the wall panel, and an inner finishing material provided on the indoor surface of the wall panel. And interior materials such as gypsum board.
The wall panel is formed of a panel core material assembled in a lattice shape and the like and a panel surface material fixed to the outdoor side of the panel core material. Further, the exterior material is formed by spraying mortar to a predetermined thickness on the outdoor surface of the wall panel.
The outer wall is provided with a rectangular opening, and the vertical extending window is a so-called internal sash window provided closer to the prospective room than the outdoor surface of the outer wall in the opening.

FIG.

躯体本体２の開口部３の上縁部には、断面略Ｌ型の役物外装材８が設けられている。この役物外装材８の一端部は、開口部３の上辺部に位置する外装材６の下端部に第１シーリング材９を介して接続されており、役物外装材８の他端部がサッシ枠５の上枠の縦片部５ａに第２シーリング材１０を介して接続されている。なお、第２シーリング材１０はＥＰＤＭゴム発泡体で形成されたエプトシーラーである。
役物外装材８と外壁躯体１の調整材４との間には、第２隙間Ｓ２が設けられており、この第２隙間Ｓ２は前記第１隙間Ｓ１と連通している。 An accessory exterior member 8 having a substantially L-shaped cross section is provided at the upper edge of the opening 3 of the housing body 2. One end of the accessory exterior material 8 is connected to the lower end of the exterior material 6 located on the upper side of the opening 3 via the first sealing material 9, and the other end of the accessory exterior material 8 is connected to the lower end of the exterior material 6. The upper frame 5a of the upper frame of the sash frame 5 is connected via a second sealing material 10. The second sealing material 10 is an ept sealer formed of EPDM rubber foam.
A second gap S2 is provided between the accessory exterior material 8 and the adjusting material 4 of the outer wall casing 1, and the second gap S2 communicates with the first gap S1.

また、第２隙間Ｓ２には、第１隙間Ｓ１から第２隙間Ｓ２に流れた水を、第２隙間Ｓ２から排水する排水手段１１が設けられている。
この排出手段１１は、所定の水勾配をもって横方向に延在するようにして設けられた樋１１である。この樋１１は、凹溝部１１ａと、樋１１を取り付けるための取付部１１ｂとを有しており、取付部１１ｂは凹溝部１１ａから上方に延出している。そして、この取付部１１ｂが躯体本体２の表面に取り付けられることによって、凹溝部１１ａが役物外装材８の内側、つまり第２隙間Ｓ２に設けられている。なお、取付部１１ｂは透湿防水シート７の下から躯体本体２の表面に取り付けられている。
凹溝部１１ａの前面は役物外装材８の内面に当接している。また、この凹溝部１１ａは前記開口部３の一方の側縁部から他方の側縁部にかけて延在しており、所定の水勾配が設けられている。例えば、凹溝部１１ａの下面は、開口部３の一方の側縁部から他方の側縁部にかけて下方に傾斜するか、または、開口部３の一方の側縁部と他方の側縁部の中央部から、それぞれ一方の縁部および他方の縁部に向けて下方に傾斜している。したがって、凹溝部１１ａにある水は水勾配に沿って流れて、凹溝部１１ａの端部から外側に流れ出て、躯体本体２と外装材６との間の第１隙間Ｓ１を下方に流れていくようになっている。 The second gap S2 is provided with drainage means 11 for draining the water that has flowed from the first gap S1 to the second gap S2 from the second gap S2.
The discharge means 11 is a trough 11 provided so as to extend laterally with a predetermined water gradient. The flange 11 has a recessed groove portion 11a and an attachment portion 11b for attaching the flange 11, and the attachment portion 11b extends upward from the recessed groove portion 11a. And by attaching this attachment part 11b to the surface of the housing body 2, the recessed groove part 11a is provided in the inside of the accessory exterior material 8, ie, 2nd clearance gap S2. In addition, the attachment part 11b is attached to the surface of the housing body 2 from under the moisture-permeable waterproof sheet 7.

The concave groove 11a extends from one side edge of the opening 3 to the other side edge, and is provided with a predetermined water gradient. For example, the lower surface of the groove 11 a is inclined downward from one side edge of the opening 3 to the other side edge, or the center of one side edge and the other side edge of the opening 3. Are inclined downward from the portion toward one edge and the other edge, respectively. Therefore, the water in the groove 11a flows along the water gradient, flows outward from the end of the groove 11a, and flows downward through the first gap S1 between the housing body 2 and the exterior material 6. It is like that.

本実施の形態によれば、第１隙間Ｓ１を下方に流れる雨水や結露水等の水は、第２隙間Ｓ２に設けられた樋１１の凹溝部１１ａに流れ込み、さらに、凹溝部１１ａをその水勾配に沿って流れ、凹溝部１１ａの端部から外側に流れ出て、躯体本体２と外装材６との間の第１隙間Ｓ１を下方に流れていくことによって排水される。したがって、水がサッシ枠５の上枠近傍の役物外装材８の内側で滞留するのを確実に防止できる。
また、調整材４の前面が、躯体本体２の前面より内側に位置しており、この調整材４に前記サッシ枠５が取り付けられているので、第２隙間Ｓ２の幅を大きくとることができる。したがって、第２隙間Ｓ２の通気性が向上するので、第２隙間Ｓ２に水が滞留するのを防止できる。 According to the present embodiment, water such as rain water and dew condensation water flowing downward through the first gap S1 flows into the concave groove portion 11a of the ridge 11 provided in the second gap S2, and further, the concave groove portion 11a passes through the water. It flows along the gradient, flows out from the end of the groove 11a, and drains by flowing downward through the first gap S1 between the housing body 2 and the exterior material 6. Therefore, water can be reliably prevented from staying inside the accessory exterior material 8 in the vicinity of the upper frame of the sash frame 5.
Moreover, since the front surface of the adjusting material 4 is located inside the front surface of the housing body 2 and the sash frame 5 is attached to the adjusting material 4, the width of the second gap S2 can be increased. . Therefore, since the air permeability of the second gap S2 is improved, water can be prevented from staying in the second gap S2.

（第２の実施の形態）
図２は、本発明に係る外壁開口部構造の第２例を示す縦断面図である。この図に示す外壁開口部構造が、図１に示す外壁開口部構造と異なる点は、排水手段であり、その他の構成要素は共通であるので、この共通構成要素には同一符号を付してその説明を省略する。
本例では、排水手段は、下方に水を抜く水抜き機能を備えた第２シーリング材１２である。第２シーリング材１２は合成樹脂等によって形成されたものであり、上下に延在する溝が複数形成されている。したがって、第１隙間Ｓ１から第２隙間Ｓ２に流れてきた水は、第２シーリング材１２の溝を通して下方に排水される。 (Second Embodiment)
