Description

本発明は面外方向に貫通して形成された開口部に二重サッシを収納した二重サッシ内蔵壁パネルに関するものである。   The present invention relates to a double sash built-in wall panel in which a double sash is accommodated in an opening formed so as to penetrate in an out-of-plane direction.

例えば屋外に面した外壁の開口部に二重サッシを収納することは、外壁において各サッシ間に形成される空気層の存在による断熱性とそれを利用した換気性能を確保する目的で採用されることが多く（特許文献１、２参照）、サッシ間の空気層に屋内、もしくは屋外の空気を通過させることにより空気層の温度変化（主に温度上昇）とそれに伴う輻射熱を抑え、屋内温度を一定に保持することが期待される。   For example, storing the double sash in the opening of the outer wall facing the outside is adopted for the purpose of ensuring heat insulation by the presence of an air layer formed between the sashes on the outer wall and ventilation performance using the sash. In many cases (see Patent Documents 1 and 2), indoor or outdoor air is allowed to pass through the air layer between the sashes to suppress the temperature change of the air layer (mainly temperature rise) and the accompanying radiant heat, thereby reducing the indoor temperature. Expected to remain constant.

一方、ユニット化されたカーテンウォールのパネルにおいても、例えば屋外の空気を屋外に面したガラスの屋内側に取り込み、ガラスの屋内側に存在する空間（空気層）を通過させることにより断熱効果と換気効果を得ることがある（特許文献３〜６参照）。   On the other hand, in the united curtain wall panel, for example, the outdoor air is taken into the indoor side of the glass facing the outside, and the space (air layer) existing on the indoor side of the glass is passed through, thereby insulating and ventilating. An effect may be acquired (refer patent documents 3-6).

二重サッシを収納する外壁においても、ガラス（障子）を収納するカーテンウォールパネルにおいても、空気層を通過した空気は屋外に排出されるか、屋内に取り込まれて循環させられることになるが、特に空気層を通過した空気を屋内に取り込む場合には、サッシ等を収納したサッシ枠の周辺に排気のためのダクトを接続することが必要になる（特許文献２、４〜６参照）。   In the outer wall that houses the double sash and the curtain wall panel that houses the glass (shoji), the air that has passed through the air layer is either discharged to the outside or taken in and circulated indoors. In particular, when taking air that has passed through the air layer indoors, it is necessary to connect a duct for exhausting around a sash frame that houses a sash or the like (see Patent Documents 2 and 6).

サッシ枠の周囲にダクトを接続する場合、ダクトはサッシ枠の内、屋内に面する見付け面とサッシ枠の外周面である見込み面のいずれかに接続されるが、サッシ等を収納するサッシ枠は概して見込み幅が見付け幅より大きい形状をするため、ダクトはサッシ枠の見込み面（外周面）に接続されることが多い（特許文献１、２）。ダクトを見付け面に接続する場合には、サッシ枠はダクトの接続のために特に適した断面形状に形成されることが必要になる（特許文献４）。   When a duct is connected around the sash frame, the duct is connected to either the locating surface facing indoors or the prospective surface that is the outer peripheral surface of the sash frame, but the sash frame that stores the sash frame, etc. Since the prospective width is generally larger than the found width, the duct is often connected to the prospective surface (outer peripheral surface) of the sash frame (Patent Documents 1 and 2). When connecting the duct to the finding surface, the sash frame needs to be formed in a cross-sectional shape particularly suitable for connecting the duct (Patent Document 4).

二重サッシ間の、もしくはガラス背面側の空気層を通過させられた空気は多くの例のようにサッシ枠の上枠から屋内に還気させられる他（特許文献１、２、５、６）、上枠を通じて屋外に排気させられる（特許文献３、４）。   The air passed between the double sashes or through the air layer on the back side of the glass is returned to the interior from the upper frame of the sash frame as in many examples (Patent Documents 1, 2, 5, and 6). The air is exhausted outdoors through the upper frame (Patent Documents 3 and 4).

上記カーテンウォールユニットとして使用される壁パネルの本体（フレーム）が例えばプレキャストコンクリート製等の場合には、コンクリート等自体が脆性材料であることで、フレーム自体は中実断面で形成されるが、その関係でフレームを構成する枠部に薄肉の部分を形成することができないため、開口部に二重サッシを収納し、フレームの例えば上枠部に二重サッシ間の空気層に連通する排気口等としての貫通孔を形成しようとする場合、貫通孔の形成位置を確保することが難しい。   When the main body (frame) of the wall panel used as the curtain wall unit is made of, for example, precast concrete, the frame itself is formed with a solid cross section because the concrete itself is a brittle material. Because a thin part cannot be formed in the frame part that constitutes the frame, the double sash is accommodated in the opening part, and the upper frame part of the frame communicates with the air layer between the double sashes, for example. When it is going to form the through-hole as, it is difficult to ensure the formation position of a through-hole.

二重サッシの内側サッシと外側サッシは採光の目的から同等の形状と面積を持ち、高さ方向に段差が付いて配置されることはないため、仮にフレームの上枠部に貫通孔を形成することができたとしても、貫通孔は内側サッシと外側サッシ間の空気層に連通するよう、上枠部を見付け方向（パネルの面内方向）に貫通する形で形成されざるを得ない。   The inner sash and the outer sash of the double sash have the same shape and area for the purpose of lighting, and are not arranged with a step in the height direction, so a through hole is temporarily formed in the upper frame part of the frame Even if it is possible, the through hole must be formed so as to penetrate in the direction of finding the upper frame (in-plane direction of the panel) so as to communicate with the air layer between the inner sash and the outer sash.

従ってその貫通孔にダクトを接続しようとすれば、ダクトをフレームの外周側に配置せざるを得ないため、特許文献２、５、６のようにフレーム外の部位との取り合いを必要とし、ダクトの敷設が各層（各階）単位での工事では済まなくなることもあり、ダクトの敷設工事の複雑化を余儀なくされることになる。   Accordingly, if a duct is to be connected to the through-hole, the duct must be arranged on the outer peripheral side of the frame, and therefore, as in Patent Documents 2, 5, and 6, it is necessary to engage with a part outside the frame. However, the construction of the ducts may not be completed by each layer (each floor) unit, which complicates the construction of the ducts.

本発明は上記背景より、パネル本体であるフレームがプレキャストコンクリート等の中実断面である場合にも、サッシを収納する開口部の周囲のフレーム（枠部）の見付け面に、空気層を通過させた空気を排出するための排気口、もしくは還気するための還気口を形成可能な形態の二重サッシ内蔵壁パネルを提案するものである。   In the present invention, the air layer is passed through the finding surface of the frame (frame portion) around the opening for housing the sash even when the frame as the panel body has a solid cross section such as precast concrete. The present invention proposes a double sash built-in wall panel capable of forming an exhaust port for exhausting air or a return air port for returning air.

「壁パネル」は壁として使用されるユニット化された版のことであり、主に外壁に使用されるが、耐力壁（耐震壁を含む）か非耐力壁（間仕切り壁）かを問わず、内壁に使用されることもある。外壁に使用される場合には、耐力壁としての外壁に形成された開口部に収納される場合と、カーテンウォールのパネルとして躯体に支持される場合がある。壁パネルが屋内の内壁に使用されることもあることから、壁パネルを挟んだ一方側（内側）と他方側（外側）を室内側と室外側を呼ぶが、内壁に使用される壁パネルを隔てた室の内外は相対的な関係に過ぎず、一方の室の室内側は他方の室の室外側になる。室外は屋外を含む。   A “wall panel” is a unitized plate used as a wall, and is mainly used for outer walls. Regardless of whether it is a load-bearing wall (including earthquake-resistant wall) or a non-bearing wall (partition wall), Sometimes used for inner walls. When used as an outer wall, it may be housed in an opening formed in the outer wall as a load bearing wall, or may be supported by a housing as a curtain wall panel. Since wall panels are sometimes used for indoor inner walls, one side (inner side) and the other side (outer side) sandwiching the wall panel are called indoor side and outdoor side. The inside and outside of the separated chambers are only a relative relationship, and the indoor side of one chamber is the outdoor side of the other chamber. Outdoor includes outdoor.

「サッシ」はガラス、もしくはそれに類似するアクリル板等の合成樹脂板（以下、ガラス等と言う）とその周囲を保持する框組みからなる障子単体の場合と、障子（ガラス等）を嵌殺し状態に、もしくは開閉自在に収納したサッシ枠を含む場合がある。開口部を除くフレームはプレキャストコンクリート、もしくはコンクリートと同等のモルタル、合成樹脂、あるいはアルミニウム合金等で形成され、材料に応じ、中実断面で形成される。 "Sash" is a single shoji made of glass or a synthetic resin plate (hereinafter referred to as glass, etc.) such as an acrylic plate, and a braid that holds the surrounding area, and a state in which the shoji (glass, etc.) is inserted. Or a sash frame that can be freely opened and closed. Frame except the opening is formed by precast concrete or concrete equivalent mortar, synthetic resin or an aluminum alloy or the like, depending on the material, it is formed in solid cross section.

「開口部が厚さ方向に貫通」とは、開口部が壁パネルの厚さ方向に貫通していることを言う。壁パネルの厚さ方向とフレームの厚さ方向は同義である。フレームは壁パネルの内、開口部を除いた部分であり、開口部を包囲するように周回し、開口部上下の上枠部と下枠部、及び幅方向両側の縦枠部とに区分される。開口部は壁パネルの厚さ方向には内側サッシが収納される内側開口部と外側サッシが収納される外側開口部とに区分される。   “The opening penetrates in the thickness direction” means that the opening penetrates in the thickness direction of the wall panel. The thickness direction of the wall panel is synonymous with the thickness direction of the frame. The frame is a portion of the wall panel excluding the opening. The frame wraps around the opening and is divided into an upper frame portion and a lower frame portion above and below the opening portion, and vertical frame portions on both sides in the width direction. The The opening is divided in the thickness direction of the wall panel into an inner opening for accommodating the inner sash and an outer opening for accommodating the outer sash.

「互いに異なる立面形状をする内側開口部と外側開口部」とは、内側開口部と外側開口部が、それぞれを壁パネルの室内側と室外側から見たときに異なる立面形状をしていることである。「異なる立面形状」とは、例えば内側開口部と外側開口部が方形状をしている場合に、互いに同一（合同）でない方形状をしていることであり、具体的には図１に示すように内側開口部と外側開口部のいずれか一方の高さ寸法（内法）が他方の高さ寸法より小さい（大きい）か、図２に示すようにいずれか一方の幅寸法（内法）が他方の幅寸法より小さい（大きい）ことを言う。但し、内側開口部と外側開口部は共に、必ずしも方形状である必要はない。   “Inner and outer openings having different elevational shapes” means that the inner and outer openings have different elevational shapes when viewed from the indoor side and the outdoor side of the wall panel. It is that you are. “Different elevation shape” means that, for example, when the inner opening and the outer opening have a rectangular shape, they have a rectangular shape that is not the same (congruent) with each other. As shown in FIG. 2, the height dimension (inner method) of either the inner opening or the outer opening is smaller (larger) than the other height dimension, or as shown in FIG. ) Is smaller (larger) than the other width dimension. However, both the inner opening and the outer opening are not necessarily rectangular.

「内側開口部と外側開口部にそれぞれ異なる寸法の内側サッシと外側サッシが収納される」とは、内側開口部と外側開口部の内法に対応した寸法の内側サッシと外側サッシがそれぞれに収納されることを言う。内側サッシ４と外側サッシ５はそれぞれ内側開口部３１と外側開口部３２の内周側に、図１、図２における外側サッシ５のように完全に納まる（内付けされる）場合と、内側サッシ４のように壁パネル１の面外方向（見込み方向）に突出して納まる（外付け・半外付けされる）場合がある。内側開口部３１と外側開口部３２のそれぞれに内側サッシ４と外側サッシ５が収納されることで、内側サッシ４の室外側の面と外側サッシ５の室内側の面との間に空気層６が形成される。   “Inner sash and outer sash of different sizes are stored in the inner opening and outer opening, respectively” means that the inner sash and outer sash of the size corresponding to the inner method of the inner opening and outer opening are stored in each. Say that will be. The inner sash 4 and the outer sash 5 are completely fitted (internally attached) on the inner peripheral side of the inner opening 31 and the outer opening 32, respectively, as in the outer sash 5 in FIGS. As shown in FIG. 4, the wall panel 1 may be protruded and stored in the out-of-plane direction (forecast direction) (externally or semi-externally attached). The inner sash 4 and the outer sash 5 are housed in the inner opening 31 and the outer opening 32, respectively, so that the air layer 6 is formed between the outdoor surface of the inner sash 4 and the indoor surface of the outer sash 5. Is formed.

図１は外側開口部３２の高さ寸法（内法）が内側開口部３１の高さ寸法（内法）より大きい場合の壁パネル１の形成例を示す。ここに示すように下枠部２２における外側開口部３２の内周面（上向き面：見込み面）と内側開口部３１の内周面（上向き面：見込み面）が同等のレベルに位置し、実質的に揃えられている場合、内側開口部３１と外側開口部３２が互いに異なる立面形状をすることで、開口部３を除いたフレーム２を構成する上枠部２１と下枠部２２、及び縦枠部２３、２３の少なくともいずれかの枠部の室内側を向く室内側見付け面の見付け幅と室外側を向く室外側見付け面の見付け幅を相違させることが可能になる。   FIG. 1 shows an example of forming the wall panel 1 when the height dimension (inner method) of the outer opening 32 is larger than the height dimension (inner method) of the inner opening 31. As shown here, the inner peripheral surface (upward surface: prospective surface) of the outer opening 32 in the lower frame portion 22 and the inner peripheral surface (upward surface: prospective surface) of the inner opening 31 are located at the same level, and substantially If the inner opening 31 and the outer opening 32 have different elevational shapes, the upper frame part 21 and the lower frame part 22 constituting the frame 2 excluding the opening part 3, and It is possible to make the finding width of the indoor-side finding surface facing the indoor side of at least one of the vertical frame portions 23, 23 different from the finding width of the outdoor-side finding surface facing the outdoor side.

図１、図２の例では上枠部２１の室内側見付け面２１ａの見付け幅が室外側見付け面２１ｂの見付け幅より大きく、一方の縦枠部２３の室内側見付け面２３ａの見付け幅が室外側見付け面２３ｂの見付け幅より大きくなっているが、内側開口部３１と外側開口部３２の立面形状と面積に応じ、上枠部２１のみ等、いずれか１本の枠部のみの見付け幅が室内側と室外側とで相違する場合と、いずれか２本以上の枠部の見付け幅が室内側と室外側とで相違する場合がある。   In the example of FIGS. 1 and 2, the finding width of the indoor-side finding surface 21a of the upper frame portion 21 is larger than the finding width of the outdoor-side finding surface 21b, and the finding width of the indoor-side finding surface 23a of one vertical frame portion 23 is the room. Although it is larger than the finding width of the outer finding surface 23b, the finding width of only one of the frame portions, such as only the upper frame portion 21, depending on the elevation shape and area of the inner opening portion 31 and the outer opening portion 32. May be different between the indoor side and the outdoor side, and the finding width of any two or more frame portions may be different between the indoor side and the outdoor side.

請求項１ではフレーム２を構成する上枠部２１と下枠部２２、及び縦枠部２３、２３の少なくともいずれかの枠部の、室内側見付け面２１ａの見付け幅と室外側見付け面２１ｂの見付け幅を相違させることができる結果、室内側見付け面２１ａと室外側見付け面２１ｂの内、見付け幅が大きい見付け面（室内側見付け面２１ａ）の反対側の、二重サッシ４、５間に形成される空気層６に面する位置に中間部見付け面２１ｃを形成することが可能になる（請求項２）。中間部見付け面２１ｃは上枠部２１と下枠部２２、及び縦枠部２３、２３の少なくともいずれかの枠部の見込み方向中間部に形成される。「見付け面の反対側の面」は枠部での見付け面の反対側に位置する面を指す。   In claim 1, the finding width of the indoor side finding surface 21 a and the outside finding surface 21 b of at least one of the upper frame portion 21, the lower frame portion 22, and the vertical frame portions 23, 23 constituting the frame 2. As a result of the difference in the finding width, between the double sashes 4 and 5 on the opposite side of the finding surface (indoor finding surface 21a) having a large finding width among the indoor finding surface 21a and the outdoor finding surface 21b. It is possible to form the intermediate portion finding surface 21c at a position facing the air layer 6 to be formed (claim 2). The intermediate portion finding surface 21 c is formed in the prospective direction intermediate portion of at least one of the upper frame portion 21, the lower frame portion 22, and the vertical frame portions 23 and 23. The “surface opposite to the finding surface” refers to a surface located on the opposite side of the finding surface in the frame portion.

図１の上枠部２１で言えば、室内側見付け面２１ａの見付け幅が室外側見付け面２１ｂの見付け幅より大きいため、室内側見付け面２１ａの反対側に空気層６に面する中間部見付け面２１ｃが形成される。図１の上枠部２１が室内側と室外側を入れ換えた形になった場合には、室外側見付け面２１ｂの見付け幅が室内側見付け面２１ａの見付け幅より大きくなるため、室外側見付け面２１ｂの反対側に空気層６に面する中間部見付け面２１ｃが形成されることになる。   Speaking of the upper frame portion 21 in FIG. 1, since the finding width of the indoor-side finding surface 21 a is larger than the finding width of the outdoor-side finding surface 21 b, the intermediate portion finding facing the air layer 6 on the opposite side of the indoor-side finding surface 21 a is found. Surface 21c is formed. When the upper frame portion 21 in FIG. 1 has a shape in which the indoor side and the outdoor side are interchanged, the finding width of the outdoor finding surface 21b is larger than the finding width of the indoor finding surface 21a. An intermediate portion finding surface 21c facing the air layer 6 is formed on the opposite side of 21b.

また図２に示す一方の縦枠部２３（室内から室外を見たときの左側の縦枠部２３）に着目すれば、室内側見付け面２３ａの見付け幅が室外側見付け面２３ｂの見付け幅より大きいため、室内側見付け面２３ａの反対側に空気層６に面する中間部見付け面２３ｃが形成される。ここでも縦枠部２３が室内側と室外側を入れ換えた形になった場合には、室外側見付け面２３ｂの見付け幅が室内側見付け面２３ａの見付け幅より大きくなるため、室外側見付け面２３ｂの反対側に空気層６に面する中間部見付け面２３ｃが形成されることになる。   If attention is paid to one vertical frame portion 23 shown in FIG. 2 (the left vertical frame portion 23 when the outside is viewed indoors), the finding width of the indoor-side finding surface 23a is larger than the finding width of the outdoor-side finding surface 23b. Since it is large, an intermediate portion finding surface 23c facing the air layer 6 is formed on the opposite side of the indoor side finding surface 23a. Here, when the vertical frame portion 23 has a shape in which the indoor side and the outdoor side are interchanged, the finding width of the outdoor finding surface 23b is larger than the finding width of the indoor finding surface 23a. An intermediate portion finding surface 23c facing the air layer 6 is formed on the opposite side.

請求項２では枠部の見込み方向中間部の空気層６に面する位置に中間部見付け面２１ｃが形成されることで、中間部見付け面２１ｃとその反対側の、見付け幅が大きい室内側見付け面２１ａ、もしくは室外側見付け面２１ｂとの間に、還気口、もしくは排気口として利用可能な貫通孔２４を形成することが可能になる（請求項３）。貫通孔２４は枠部を見込み方向に貫通して形成される。   In claim 2, the intermediate portion finding surface 21c is formed at a position facing the air layer 6 in the intermediate portion in the prospective direction of the frame portion, so that the intermediate portion finding surface 21c and the opposite side of the intermediate portion finding surface 21c have a large finding width. A through-hole 24 that can be used as a return air outlet or an exhaust port can be formed between the surface 21a or the outdoor-side finding surface 21b (Claim 3). The through hole 24 is formed through the frame portion in the prospective direction.

図１の例では上枠部２１における外側開口部３２の内周面（下向き面：：見込み面２１ｄ）が内側開口部３１の内周面（下向き面：見込み面２１ｆ）より上に位置し、外側開口部３２の内周面（見込み面２１ｄ）と内側開口部３１の内周面（見込み面２１ｆ）をつなぐ中間部見付け面２１ｃは外側サッシ５の室内側に位置し、室外側を向いた状態で外側サッシ５の室内側に存在する空気層６に面する。この場合の上枠部２１では中間部見付け面２１ｃとその反対側の室内側見付け面２１ａとの間に枠部（上枠部２１）を見込み方向に貫通する貫通孔２４が形成される。図１の上枠部２１が室内側と室外側を入れ換えた形になった場合には、中間部見付け面２１ｃとその反対側の室外側見付け面２１ｂとの間に貫通孔２４が形成される。   In the example of FIG. 1, the inner peripheral surface (downward surface :: prospective surface 21 d) of the outer opening 32 in the upper frame portion 21 is located above the inner peripheral surface (downward surface: prospective surface 21 f) of the inner opening 31. An intermediate portion finding surface 21c that connects the inner peripheral surface (expected surface 21d) of the outer opening 32 and the inner peripheral surface (expected surface 21f) of the inner opening 31 is located on the indoor side of the outer sash 5, and faces the outdoor side. It faces the air layer 6 existing on the indoor side of the outer sash 5 in a state. In this case, in the upper frame portion 21, a through hole 24 penetrating the frame portion (upper frame portion 21) in the prospective direction is formed between the intermediate portion finding surface 21c and the indoor side finding surface 21a on the opposite side. When the upper frame portion 21 in FIG. 1 has a shape in which the indoor side and the outdoor side are interchanged, a through-hole 24 is formed between the intermediate portion finding surface 21c and the opposite outdoor side finding surface 21b. .

図２では前記一方の縦枠部２３における外側開口部３２の内周面（見込み面２３ｄ）が内側開口部３１の内周面（見込み面２３ｆ）より開口部３の中心に対して外周側に位置し、外側開口部３２の内周面（見込み面２３ｄ）と内側開口部３１の内周面（見込み面２３ｆ）をつなぐ中間部見付け面２３ｃは外側サッシ５の室内側に位置し、室外側を向いた状態で外側サッシ５の室内側に存在する空気層６に面する。   In FIG. 2, the inner peripheral surface (expected surface 23 d) of the outer opening 32 in the one vertical frame portion 23 is on the outer peripheral side with respect to the center of the opening 3 from the inner peripheral surface (expected surface 23 f) of the inner opening 31. An intermediate portion finding surface 23c that is located and connects the inner peripheral surface (expected surface 23d) of the outer opening 32 and the inner peripheral surface (expected surface 23f) of the inner opening 31 is located on the indoor side of the outer sash 5, and It faces the air layer 6 existing on the indoor side of the outer sash 5 in a state of facing.

この一方の縦枠部２３では中間部見付け面２３ｃとその反対側の室内側見付け面２３ａとの間に二点鎖線で示すように枠部（縦枠部２３）を見込み方向に貫通する貫通孔２４が形成可能になっている。図２の一方の縦枠部２３が室内側と室外側を入れ換えた形になった場合には、中間部見付け面２３ｃとその反対側の室外側見付け面２３ｂとの間に貫通孔２４が形成可能になる。貫通孔２４が形成される枠部は上枠部２１と縦枠部２３には限られず、下枠部２２に形成されることもある。   In this one vertical frame portion 23, a through-hole penetrating the frame portion (vertical frame portion 23) in the prospective direction as shown by a two-dot chain line between the intermediate portion finding surface 23c and the indoor side finding surface 23a on the opposite side. 24 can be formed. When one vertical frame portion 23 in FIG. 2 has a shape in which the indoor side and the outdoor side are interchanged, a through-hole 24 is formed between the intermediate portion finding surface 23c and the opposite outdoor side finding surface 23b. It becomes possible. The frame part in which the through hole 24 is formed is not limited to the upper frame part 21 and the vertical frame part 23, and may be formed in the lower frame part 22.

また図１に示す例の上枠部２１における外側開口部３２の内周面（見込み面２１ｄ）と、図２に示す例の一方の縦枠部２３における外側開口部３２の内周面（見込み面２３ｄ）の、外側サッシ５より室内側に位置する部分（区間）は中間部見付け面２１ｃ、２３ｃに連続することで、二重サッシ４、５間の空気層６に面する状態にあるため、これらの両枠部２１、２３における外側開口部３２の内周面（見込み面２１ｄ、２３ｄ）は空気層６を通過した空気を、外側開口部３２を通じて室外側へ排出するために利用可能となる。   Moreover, the inner peripheral surface (expected surface 21d) of the outer opening portion 32 in the upper frame portion 21 in the example shown in FIG. 1 and the inner peripheral surface (expected portion) of one vertical frame portion 23 in the example shown in FIG. A portion (section) of the surface 23d) located on the indoor side from the outer sash 5 is continuous with the intermediate portion finding surfaces 21c and 23c, and thus faces the air layer 6 between the double sashes 4 and 5. The inner peripheral surfaces (prospective surfaces 21d and 23d) of the outer opening 32 in both the frame parts 21 and 23 can be used to discharge the air that has passed through the air layer 6 to the outdoor side through the outer opening 32. Become.

具体的には例えば図１における上枠部２１の室外側の部分と図２における縦枠部２３の室外側の部分に二点鎖線で示すように外側開口部３２の内周面（見込み面２１ｄ、２３ｄ）から、各枠部２１、２３の室外側見付け面２１ｂ、２３ｂとの間に連続する、排気口としての貫通孔２１ｅ、２３ｅを形成することで、空気層６を通過した空気を外側開口部３２の内周面（見込み面２１ｄ、２３ｄ）から室外へ排出することが可能である。外側開口部３２の内周面（見込み面２１ｄ、２３ｄ）を通じた排気の状況は図４−（ｂ）、（ｄ）に示す排気の形態に相当する。   Specifically, for example, the inner peripheral surface (expected surface 21d) of the outer opening 32 as indicated by a two-dot chain line in the outdoor portion of the upper frame portion 21 in FIG. 1 and the outdoor portion of the vertical frame portion 23 in FIG. 23d), through holes 21e and 23e as exhaust ports that are continuous between the outdoor side finding surfaces 21b and 23b of the frame portions 21 and 23, the air that has passed through the air layer 6 is It is possible to discharge from the inner peripheral surface (expected surfaces 21d, 23d) of the opening 32 to the outside of the room. The state of exhaust through the inner peripheral surface (expected surfaces 21d, 23d) of the outer opening 32 corresponds to the exhaust form shown in FIGS. 4- (b) and (d).

貫通孔２４は枠部（フレーム２）が中実断面の場合、中間部見付け面２１ｃと室内側見付け面２１ａ、もしくは室外側見付け面２１ｂとの間に貫通して形成されればよく、例えばフレーム２を成形するための型枠（堰板）内の貫通孔２４の形成位置に中空断面の、または離脱可能な部材を埋設しておくことで形成される。枠部が中空断面の場合には、中間部見付け面２１ｃと室内側見付け面２１ａ、もしくは室外側見付け面２１ｂへの孔の形成では還気、もしくは排気すべき空気が枠部の内部に漏れるため、枠部の中間部見付け面２１ｃと室内側見付け面２１ａ、もしくは室外側見付け面２１ｂとの間に中空の管を跨設することにより貫通孔２４を枠部の内部に連通させることなく形成することが必要になる。
When the frame portion (frame 2) has a solid cross section, the through hole 24 may be formed so as to penetrate between the intermediate portion finding surface 21c and the indoor side finding surface 21a or the outdoor side finding surface 21b. 2 is formed by embedding a hollow cross-section or detachable member at a position where the through hole 24 is formed in a mold (dam plate) for molding 2. When the frame portion has a hollow cross section, return air or air to be exhausted leaks into the inside of the frame portion when forming holes in the intermediate portion finding surface 21c and the indoor side finding surface 21a or the outdoor side finding surface 21b. The through hole 24 is formed without communicating with the inside of the frame portion by straddling a hollow tube between the intermediate portion finding surface 21c of the frame portion and the indoor side finding surface 21a or the outdoor side finding surface 21b. it is ing to need.

請求項３では見付け幅が大きい室内側見付け面２１ａ、もしくは室外側見付け面２１ｂと空気層６に面する中部見付け面２１ｃとの間に貫通孔２４を形成可能であることで、空気層６を通過した空気を室内側へ取り込むための還気用等のダクト８等をフレーム２のいずれかの枠部の室内側に直接、接続することが可能になる。この結果、ダクト８等とフレーム２（壁パネル１）外の部位との取り合いが不要になるため、ダクト８の敷設を各層（各階）単位で済ませることができ、敷設工事が単純化される。貫通孔２４を還気口として利用する場合、還気口に入り込む空気は一旦、室内に取り込まれた後に、ダクト８を通じて室外（屋外）へ排出されることもあり、その場合には還気口（貫通孔２４）は結果的には排気口になる。   According to the third aspect, the through hole 24 can be formed between the indoor-side finding surface 21a or the outdoor-side finding surface 21b having a large finding width and the middle finding surface 21c facing the air layer 6, so that the air layer 6 is formed. It becomes possible to directly connect a duct 8 or the like for returning air for taking in the air that has passed into the room to the room inside of any frame portion of the frame 2. As a result, since the connection between the duct 8 and the like and the portion outside the frame 2 (wall panel 1) is not required, the laying of the duct 8 can be completed in units of each layer (each floor), and the laying work is simplified. When the through hole 24 is used as a return air port, the air that enters the return air port is once taken into the room and then discharged to the outside (outdoor) through the duct 8. The (through hole 24) eventually becomes an exhaust port.

図１における上枠部２１の中間部見付け面２１ｃと外側サッシ５のガラス等、障子５１の室内側の面との間には内側サッシ４との間に存在する空気層６に連続するクリアランスがフレーム２（枠部）の見込み方向（厚さ方向）に形成され、中間部見付け面２１ｃはこのクリアランスに面することで、空気層６に面する状態にある。空気層６は外側サッシ５の障子５１の室内側の面と内側サッシ４のガラス等、障子４１の室外側の面との間に形成され、内側サッシ４と外側サッシ５間の空気層６を通過した空気はクリアランスを経由して上枠部２１の中間部見付け面２１ｃに到達する。   The clearance which continues to the air layer 6 which exists between the inner side sash 4 between the intermediate | middle part finding surface 21c of the upper frame part 21 in FIG. It is formed in the prospective direction (thickness direction) of the frame 2 (frame part), and the intermediate part finding surface 21c faces the air layer 6 by facing this clearance. The air layer 6 is formed between the indoor surface of the shoji 51 of the outer sash 5 and the outdoor surface of the shoji 41 such as the glass of the inner sash 4, and the air layer 6 between the inner sash 4 and the outer sash 5 is formed. The passed air reaches the intermediate part finding surface 21c of the upper frame part 21 via the clearance.

従って図１の例で言えば、上枠部２１において空気層６に面する中間部見付け面２１ｃとその反対側に位置する（反対側の面である）室内側見付け面２１ａとの間に両面間を貫通する貫通孔２４が形成されれば、貫通孔２４は空気層６と室内の双方に連通するため、空気層６を通過した空気を二重サッシの外側である室内側へ、または室内を通じて室外側へ排出することが可能になる。   Therefore, in the example of FIG. 1, both surfaces of the upper frame portion 21 are provided between the intermediate portion finding surface 21c facing the air layer 6 and the indoor side finding surface 21a located on the opposite side (the opposite surface). If the through-hole 24 penetrating therethrough is formed, the through-hole 24 communicates with both the air layer 6 and the room. Therefore, the air that has passed through the air layer 6 is directed to the indoor side that is outside the double sash or the room. It becomes possible to discharge to the outdoor side through.

ここで、図１に示す壁パネル１は外側開口部３２の高さ寸法が内側開口部３１の高さ寸法より大きいことで、上枠部２１は室内側見付け面２１ａの見付け幅が室外側見付け面２１ｂの見付け幅より大きい形状をするため、室内側見付け面２１ａに突き合わせる形でダクト８等を接続するだけで、貫通孔２４にダクト８等を連通させることが可能であり、壁パネル１の範囲外に及ぶことなく、壁パネル１の立面の範囲内にダクト８を配置すればよくなる。図１に示す例の場合、上枠部２１の室内側見付け面２１ａの領域（範囲）内に、具体的には室内側見付け面２１ａの内、室外側見付け面２１ｂの重なり部分を除いた領域（範囲）内に貫通孔２４が形成されるため、室内側見付け面２１ａに直接、上記したダクト８を突き合わせて接続することが可能になっている。   Here, in the wall panel 1 shown in FIG. 1, the height dimension of the outer opening 32 is larger than the height dimension of the inner opening 31, so that the upper frame portion 21 has a finding width of the indoor-side finding surface 21a. Since the shape is larger than the finding width of the surface 21b, it is possible to connect the duct 8 and the like to the through hole 24 simply by connecting the duct 8 and the like so as to abut against the indoor-side finding surface 21a. What is necessary is just to arrange | position the duct 8 in the range of the elevation of the wall panel 1, without extending outside the range. In the case of the example shown in FIG. 1, a region within the region (range) of the indoor-side finding surface 21 a of the upper frame portion 21, specifically, the region excluding the overlapping portion of the indoor-side finding surface 21 a and the outdoor-side finding surface 21 b. Since the through hole 24 is formed in (range), the above-described duct 8 can be directly abutted and connected to the indoor-side finding surface 21a.

以上のことを整理すれば、請求項１の「内側開口部３１と外側開口部３２が互いに異なる立面形状をすること」の要件から「フレーム２を構成する上枠部２１と下枠部２２、及び縦枠部２３、２３の内、少なくともいずれかの枠部の室内側見付け面２１ａの見付け幅と室外側見付け面２１ｂの見付け幅が相違すること」が言える。この要件から直接的に「室内側見付け面２１ａと室外側見付け面２１ｂの内、見付け幅が大きい見付け面の反対側に、空気層６に面する中間部見付け面２１ｃが形成されること」（請求項２）の要件が導出される。更に「中間部見付け面２１ｃが空気層６に面する状態で形成されること」の要件から「見付け幅の大きい室内側見付け面２１ａ、もしくは室外側見付け面２１ｂとそれに対向する中間部見付け面２１ｃとの間に貫通孔２４が形成可能であること」の要件が導出される（請求項３）。   To summarize the above, from the requirement “the inner opening 31 and the outer opening 32 have different elevational shapes” according to claim 1, “the upper frame portion 21 and the lower frame portion 22 constituting the frame 2”. It can also be said that the finding width of the indoor-side finding surface 21a and the finding width of the outdoor-side finding surface 21b of at least one of the vertical frame portions 23 and 23 are different. Directly from this requirement, “the intermediate part finding surface 21c facing the air layer 6 is formed on the opposite side of the finding surface having the large finding width among the indoor finding surface 21a and the outdoor finding surface 21b” (see FIG. The requirement of claim 2) is derived. Furthermore, from the requirement that “the intermediate portion finding surface 21c is formed in a state facing the air layer 6,” “the indoor side finding surface 21a or the outdoor side finding surface 21b having a large finding width and the intermediate portion finding surface 21c opposed thereto”. The requirement that the through hole 24 can be formed between them is derived (claim 3).

外側サッシ５と内側サッシ４間の空気層６には例えば図１に示すように下枠部２２と内側サッシ４との間に形成された通気口（通気孔）２５から室内空気（内気）が送り込まれるか、または下枠部２２と外側サッシ５との間に形成される通気口（通気孔）２５から室外空気（外気）が取り込まれる。すなわち、通気口（通気孔）２５は貫通孔２４が形成された枠部（上枠部２１）以外の枠部（下枠部２２、もしくは縦枠部２３）、もしくはその枠部に保持される少なくともいずれかのサッシの枠（サッシ枠４２、５２）、または枠部とサッシの枠（サッシ枠４２、５２）との間の少なくともいずれかに形成され、室内、もしくは室外に連通する（請求項４）。通気口の「口」はフレーム２の枠部、もしくはサッシ枠、框等に穿設される孔と、枠部とサッシ枠間、またはサッシ枠と框間等に確保される空隙等の空間その他、開口全般を含む。   In the air layer 6 between the outer sash 5 and the inner sash 4, for example, as shown in FIG. 1, indoor air (inside air) is supplied from a vent (vent hole) 25 formed between the lower frame portion 22 and the inner sash 4. Outdoor air (outside air) is taken in through a vent (vent hole) 25 that is fed in or formed between the lower frame portion 22 and the outer sash 5. That is, the vent hole (vent hole) 25 is held in a frame part (lower frame part 22 or vertical frame part 23) other than the frame part (upper frame part 21) in which the through hole 24 is formed, or in the frame part. It is formed in at least one of at least one of the sash frames (sash frames 42 and 52) or between the frame portion and the sash frames (sash frames 42 and 52), and communicates indoors or outdoors (claims). 4). The “mouth” of the ventilation hole is a space such as a hole secured in the frame part of the frame 2 or a sash frame, a sash frame, a space between the frame part and the sash frame, or a space secured between the sash frame and the sash, etc. Including all openings.

ここで言う「枠部」は壁パネル１のフレーム２を構成する上枠部２１と下枠部２２、及び縦枠部２３、２３の少なくともいずれかの枠部を指し、「サッシの枠」は内側開口部３１に収納される内側サッシ４、もしくは外側開口部３２に収納される外側サッシ５の枠（サッシ枠４２、５２）であり、上枠４２１、５２１、下枠４２２、５２２、縦枠４２３、５２３の少なくともいずれかを指す。室内側の通気口２５は例えば図１に示すようにサッシ枠４２を構成する下枠４２２と内側サッシ４の下框４１２との間に空隙を確保するか、または下枠４２２の、室内に面するいずれかの部分に孔を穿設するか、ガラリを配置する、あるいは無双窓式のスライド自在な板を配置することにより形成される。室外側の通気口２５も同様である。   The “frame portion” here refers to at least one of the upper frame portion 21 and the lower frame portion 22 and the vertical frame portions 23 and 23 constituting the frame 2 of the wall panel 1, and the “sash frame” is A frame (sash frames 42 and 52) of the inner sash 4 accommodated in the inner opening 31 or the outer sash 5 accommodated in the outer opening 32 (sash frames 42 and 52), upper frames 421 and 521, lower frames 422 and 522, vertical frames 423 or 523 is pointed out. For example, as shown in FIG. 1, the air vent 25 on the indoor side secures a gap between the lower frame 422 constituting the sash frame 42 and the lower collar 412 of the inner sash 4, or the lower frame 422 faces the room. It is formed by drilling a hole in any of the parts, disposing a louver, or disposing a windowless slidable plate. The same applies to the vent hole 25 on the outdoor side.

請求項４では貫通孔２４が上枠部２１と下枠部２２と縦枠部２３のいずれかに形成され、空気層６を通過する空気が、貫通孔２４が形成される枠部以外のいずれかの枠部の通気口２５から取り込まれることで、図４−（ａ）〜（ｄ）に示すように空気の取り込み口（導入口）としての通気口２５と空気層６を通過した空気の排出口、もしくは還気口としての貫通孔２４の組み合わせを複数通りに設定することが可能である。   In claim 4, the through hole 24 is formed in any one of the upper frame portion 21, the lower frame portion 22, and the vertical frame portion 23, and any air other than the frame portion in which the through hole 24 is formed is allowed to pass through the air layer 6. By being taken in from the vent 25 in the frame part, the air that has passed through the vent 25 and the air layer 6 as an air intake (inlet) as shown in FIGS. It is possible to set a plurality of combinations of the through holes 24 as discharge ports or return air ports.

図４−（ａ）は図１の例と同じく通気口２５を下枠部２２の室内側に形成し、還気口としての貫通孔２４を上枠部２１の室内側に形成した場合、（ｂ）は通気口２５を下枠部２２の室内側に形成し、排出口としての貫通孔２４を上枠部２１の室外側に形成した場合である。（ｃ）は通気口２５を下枠部２２の室外側に形成し、還気口としての貫通孔２４を上枠部２１の室内側に形成した場合、（ｄ）は通気口２５を下枠部２２の室外側に形成し、排出口としての貫通孔２４を上枠部２１の室外側に形成した場合である。   4A, when the vent 25 is formed on the indoor side of the lower frame portion 22 and the through hole 24 as the return air port is formed on the indoor side of the upper frame portion 21, as in the example of FIG. b) shows a case where the air vent 25 is formed on the indoor side of the lower frame portion 22 and the through hole 24 as a discharge port is formed on the outdoor side of the upper frame portion 21. (C) is a case where the air vent 25 is formed on the outdoor side of the lower frame portion 22 and the through hole 24 as a return air port is formed on the indoor side of the upper frame portion 21, and FIG. This is a case where it is formed on the outdoor side of the portion 22 and a through hole 24 as a discharge port is formed on the outdoor side of the upper frame portion 21.

但し、図４の各図に矢印で示すように下枠部２２における通気口２５と、上枠部２１における還気口、もしくは排気口としての貫通孔２４、あるいは貫通孔２１ｅは季節に応じて互いに逆転することもあり、上枠部２１の貫通孔２４、２１ｅが導入口としての通気口になり、下枠部２２の通気口が還気口、もしくは排気口になることもある。その他、例えば通気口２５を上枠部２１、もしくは縦枠部２３に形成し、貫通孔２４、２３ｅを下枠部２２、もしくは縦枠部２３に形成する等、通気口２５と貫通孔２４、２３ｅはそれぞれ下枠部２２と上枠部２１以外にも形成可能であるから、通気口２５と貫通孔２４、２１ｅ、２３ｅ間の、空気層６を通じた通気は図４以外にも複数通りに設定可能である。   However, as shown by the arrows in each figure of FIG. 4, the vent 25 in the lower frame 22 and the through-hole 24 or the through-hole 21e as the return or exhaust in the upper frame 21 are in accordance with the season. The through holes 24 and 21e of the upper frame portion 21 may serve as an introduction port, and the ventilation port of the lower frame portion 22 may serve as a return or exhaust port. In addition, for example, the air vent 25 is formed in the upper frame portion 21 or the vertical frame portion 23, and the through holes 24 and 23e are formed in the lower frame portion 22 or the vertical frame portion 23. 23e can be formed other than the lower frame portion 22 and the upper frame portion 21, respectively. Therefore, the ventilation through the air layer 6 between the vent hole 25 and the through holes 24, 21e, 23e can be performed in a plurality of ways other than FIG. It can be set.

請求項１ではまた、内側開口部３１と外側開口部３２が互いに異なる立面形状をすることで、壁パネル１の外形線に対する外側サッシ５の外形線を任意の位置に配置することが可能になっているため、複数枚の壁パネル１が外壁７の構面に添って水平方向と鉛直方向に配列する場合に、図７に示すように各壁パネル１の外形線に対する外側サッシ５の外形線の位置を相違させることで、外壁７のデザインに変化を持たせる効果も得られる。   Further, the outer opening of the outer sash 5 with respect to the outer contour of the wall panel 1 can be arranged at an arbitrary position by forming the inner opening 31 and the outer opening 32 to have different elevational shapes. Therefore, when the plurality of wall panels 1 are arranged in the horizontal direction and the vertical direction along the construction surface of the outer wall 7, the outer shape of the outer sash 5 with respect to the outer contour line of each wall panel 1 as shown in FIG. By making the positions of the lines different, an effect of changing the design of the outer wall 7 can also be obtained.

壁パネル１は図６に示すように外壁７の構面に添った水平方向と鉛直方向にそれぞれ複数枚、配列したときに、統一感のある外壁面を構成する他、図７に示すように壁パネル１内の外側サッシ５が外壁面に無秩序に配列する等、窓の配列に変化を持たせるような外壁面を構成することが可能である。図７は同一形状で、同一寸法のフレーム２の立面形状（外郭形状）に対して異なる立面形状と面積の外側サッシ５を収納し、異なる外観を有する複数枚の壁パネル１を水平方向と鉛直方向に配列させたときの外壁面の構成例を示している。   As shown in FIG. 7, the wall panel 1 forms a uniform outer wall surface when a plurality of wall panels 1 are arranged in the horizontal direction and the vertical direction along the construction surface of the outer wall 7 as shown in FIG. It is possible to configure an outer wall surface that changes the arrangement of the windows, for example, the outer sash 5 in the wall panel 1 is randomly arranged on the outer wall surface. FIG. 7 shows a plurality of wall panels 1 having the same shape, housing different sashes 5 having different surface shapes and areas with respect to the surface shape (outer shape) of the frame 2 having the same dimensions, and having different appearances in the horizontal direction. And a configuration example of the outer wall surface when arranged in the vertical direction.

また例えば図１における上枠部２１の外周面（上端面）と下枠部２２の外周面（下端面）が図４−（ａ）〜（ｄ）に示すように平坦面に形成されているとすれば、壁パネル１（フレーム２）は面外方向（見込み方向）の両表面が室内側と室外側のいずれを向いても使用可能な形状をすることになる。   Further, for example, the outer peripheral surface (upper end surface) of the upper frame portion 21 and the outer peripheral surface (lower end surface) of the lower frame portion 22 in FIG. 1 are formed as flat surfaces as shown in FIGS. Then, the wall panel 1 (frame 2) has a shape that can be used regardless of whether the both surfaces in the out-of-plane direction (expected direction) face the indoor side or the outdoor side.

その場合、前記のように図１において貫通孔２４が形成されている室内側見付け面２１ａを室外側に向け、室外側見付け面２１ｂにしたときには、貫通孔２４は室外に連通するため、壁パネル１の向きを変えるだけで、貫通孔２４を排気口として利用し、空気層６を通過した空気を貫通孔２４を通じて二重サッシの外側である室外側へ排出することが可能になる。   In that case, when the indoor side finding surface 21a in which the through hole 24 is formed in FIG. 1 as described above is directed to the outdoor side and the outdoor side finding surface 21b is used, the through hole 24 communicates with the outdoor side. By simply changing the direction of 1, the through hole 24 can be used as an exhaust port, and the air that has passed through the air layer 6 can be discharged through the through hole 24 to the outside of the double sash.

このようにフレーム２の外周面が平坦面に形成される等、壁パネル１自身が室内側と室外側の向き（違い）を持たない場合には、同一の壁パネル１における枠部の貫通孔２４を還気用にも排気用にも使用でき、壁パネル１が室内側と室外側を単純に入れ換えて使用することに対応可能であるため、単一の壁パネル１を２通りの用途に兼用することが可能になる。   When the wall panel 1 itself does not have a direction (difference) between the indoor side and the outdoor side, such as when the outer peripheral surface of the frame 2 is formed as a flat surface in this way, the through hole of the frame portion in the same wall panel 1 24 can be used for both return air and exhaust, and the wall panel 1 can be used by simply replacing the indoor side and the outdoor side, so the single wall panel 1 can be used in two ways. It becomes possible to share.

図１に示す壁パネル１の室内側と室外側を単純に入れ換えた状態を想定すれば、上枠部２１の室外側（室外側見付け面２１ｂ）の見付け幅が大きくなるため、その室外側見付け面２１ｂの内、室内側見付け面２１ａの重なり部分を除いた領域（範囲）内に、上枠部２１を厚さ方向に貫通する貫通孔２４を形成することが可能である。このときの貫通孔２４は図１に示す壁パネル１における貫通孔２４と違いはないため、図１に示す壁パネル１の室内側と室外側を入れ換えるだけで、貫通孔２４を排気口として利用可能になる。   Assuming a state in which the indoor side and the outdoor side of the wall panel 1 shown in FIG. A through-hole 24 that penetrates the upper frame portion 21 in the thickness direction can be formed in a region (range) excluding the overlapping portion of the indoor-side finding surface 21a in the surface 21b. Since the through hole 24 at this time is not different from the through hole 24 in the wall panel 1 shown in FIG. 1, the through hole 24 can be used as an exhaust port only by replacing the indoor side and the outdoor side of the wall panel 1 shown in FIG. It becomes possible.

このように同一形態（形状）で、同一寸法の壁パネル１でありながら、室内側の面と室外側の面を入れ換えるだけで、上枠部２１等の見付け幅が大きい見付け面を室内側に向けたときに、貫通孔２４が形成された見付け面（室内側見付け面２１ａ）に還気用のダクト８を接続することができる。一方、上枠部２１等の見付け幅が大きい側を室外側に向けたときの室外側見付け面２１ｂとなる同一の見付け面に排気口（貫通孔２４）が形成されるため、１種類の壁パネル１の使用により還気と排気の２通りの設計に対応することが可能になる。室内側を向いたときの見付け面にダクト８が接続され、室外側を向いたときに排気口として利用される貫通孔２４の形成位置は上枠部２１には限らず、下枠部２２になることもあれば、縦枠部２３になることもある。   In this manner, the wall panel 1 having the same form (shape) and the same dimensions, but by simply replacing the indoor side surface and the outdoor side surface, the finding surface having a large finding width such as the upper frame portion 21 is placed on the indoor side. When turned, the return air duct 8 can be connected to the finding surface (the indoor-side finding surface 21a) in which the through holes 24 are formed. On the other hand, since the exhaust port (through hole 24) is formed on the same finding surface as the outdoor finding surface 21b when the large finding width of the upper frame portion 21 or the like is directed to the outdoor side, one type of wall is formed. Use of the panel 1 makes it possible to cope with two designs of return air and exhaust. The duct 8 is connected to the surface to be found when facing the indoor side, and the formation position of the through hole 24 used as the exhaust port when facing the outdoor side is not limited to the upper frame portion 21 but to the lower frame portion 22. Or the vertical frame portion 23.

開口部が内側開口部と外側開口部に壁パネルの厚さ方向に区分され、内側開口部と外側開口部が互いに異なる立面形状をすることで、開口部を除いたフレームを構成する上枠部と下枠部、及び縦枠部の少なくともいずれかの枠部の室内側を向く室内側見付け面の見付け幅と室外側を向く室外側見付け面の見付け幅を相違させることができる。この結果、いずれかの枠部の見付け幅が大きい室内側見付け面と、空気層に面する中間部見付け面との間に枠部を厚さ方向に貫通する貫通孔を形成することができる。   The upper frame constituting the frame excluding the opening by dividing the opening into an inner opening and an outer opening in the thickness direction of the wall panel, and the inner opening and the outer opening having different elevational shapes. The finding width of the indoor-side finding surface facing the indoor side of at least one of the frame portion, the lower frame portion, and the vertical frame portion can be made different from the finding width of the outdoor-side finding surface facing the outdoor side. As a result, a through-hole penetrating the frame portion in the thickness direction can be formed between the indoor-side finding surface where the finding width of any one of the frame portions is large and the intermediate finding surface facing the air layer.

空気層に面する中間部見付け面と室内側見付け面との間に貫通孔が形成可能であることで、室内側見付け面に直接、還気のためのダクト等を接続することができるため、壁パネルの立面の範囲内にダクト等を配置すればよく、ダクト等と壁パネル外の部位との取り合いが不要になる。この結果、ダクトの敷設を各層（各階）単位で済ませることができ、工事が単純化される。
Since a through-hole can be formed between the intermediate-side finding surface facing the air layer and the indoor-side finding surface, a duct or the like for returning air can be directly connected to the indoor-side finding surface, A duct or the like may be disposed within the range of the elevation of the wall panel, and the connection between the duct or the like and a portion outside the wall panel becomes unnecessary. As a result, ducts can be laid in units of each layer (each floor), and the construction is simplified.

FIG.

以下、図面を用いて本発明を実施するための最良の形態を説明する。   Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings.

図１、図２はサッシが収納される開口部３が厚さ方向に貫通して形成され、開口部３の周囲にフレーム２を有する二重サッシ内蔵壁パネル（以下、壁パネル）１の製作例と外壁７への設置例を示す。開口部３は図５に示すようにフレーム２の厚さ方向に、互いに異なる立面形状をする内側開口部３１と外側開口部３２とに区分され、内側開口部３１と外側開口部３２にそれぞれ異なる寸法の内側サッシ４と外側サッシ５が収納される。図５は図１、図２に示す壁パネル１の構成要素であるフレーム２と、その内側開口部３１と外側開口部３２に納まる内側サッシ４及び外側サッシ５との関係を示している。   1 and 2 show a double sash built-in wall panel (hereinafter referred to as a wall panel) 1 in which an opening 3 for accommodating a sash is formed in a thickness direction and a frame 2 is provided around the opening 3. An example and an installation example on the outer wall 7 are shown. As shown in FIG. 5, the opening 3 is divided into an inner opening 31 and an outer opening 32 that have different elevational shapes in the thickness direction of the frame 2, and is divided into an inner opening 31 and an outer opening 32, respectively. The inner sash 4 and the outer sash 5 having different dimensions are accommodated. FIG. 5 shows the relationship between the frame 2 that is a component of the wall panel 1 shown in FIGS. 1 and 2, and the inner sash 4 and the outer sash 5 that are housed in the inner opening 31 and the outer opening 32.

図１は図３に示す外壁７の一部を示し、図２は図１のｘ−ｘ線の断面を示している。図１〜図３は壁パネル１が構造物の梁、スラブ等の躯体に支持されるユニット式カーテンウォールのパネルの例を示しているが、壁パネル１は躯体としての外壁７の開口部に収納される場合と、屋内の壁に組み込まれる場合がある。図１〜図３はまた、サッシ（内側サッシ４と外側サッシ５）を除くフレーム２が中実断面のプレキャストコンクリート（モルタルを含む）製である場合の例であるが、フレーム２の材料は問われず、中実断面か否かも問われない。   1 shows a part of the outer wall 7 shown in FIG. 3, and FIG. 2 shows a cross section taken along line xx of FIG. 1 to 3 show an example of a unit type curtain wall panel in which the wall panel 1 is supported by a frame such as a beam or slab of a structure. The wall panel 1 is formed in an opening of an outer wall 7 as a frame. It may be stored or it may be built into an indoor wall. FIGS. 1 to 3 are also examples in which the frame 2 excluding the sash (the inner sash 4 and the outer sash 5) is made of solid-cast precast concrete (including mortar). It does not matter whether the cross section is solid or not.

図面では内側サッシ４が２枚の障子４１を内開き式にサッシ枠４２に収納したサッシで、外側サッシ５が１枚の障子５１（ガラス）を嵌殺し状態にサッシ枠５２に収納したサッシである場合の例を示しているが、内側開口部３１と外側開口部３２に収納される内側サッシ４と外側サッシ５の形態、すなわち固定状態に収納されるか、開閉自在に収納されるかも問われない。   In the drawing, the inner sash 4 is a sash in which two shojis 41 are housed in a sash frame 42 in an open manner, and the outer sash 5 is a sash in which one shoji 51 (glass) is fitted and housed in a sash frame 52. Although an example is shown, the inner sash 4 and the outer sash 5 stored in the inner opening 31 and the outer opening 32 may be stored in a fixed state, or may be stored in an openable / closable manner. I will not.

内側開口部３１と外側開口部３２は共に、フレーム２を構成する上枠部２１と下枠部２２、及び縦枠部２３、２３の各内周面が周回することにより形成され、各枠部の内周面が区画する内側開口部３１の立面形状と外側開口部３２の立面形状が図５に示すように相違する。   Both the inner opening portion 31 and the outer opening portion 32 are formed by the inner peripheral surfaces of the upper frame portion 21 and the lower frame portion 22 and the vertical frame portions 23 and 23 constituting the frame 2 circulated. As shown in FIG. 5, the elevational shape of the inner opening 31 and the elevational shape of the outer opening 32 defined by the inner peripheral surface are different.

図１、図２の例では下枠部２２における内側開口部３１の内周面（上向き面：見込み面）と外側開口部３２の内周面（上向き面：見込み面）がほぼ揃えられ、上枠部２１における内側開口部３１の内周面（下向き面：見込み面２１ｆ）と外側開口部３２の内周面（下向き面：見込み面２１ｄ）との間に段差が形成され、この段差の存在によって上枠部２１の内側開口部３１の内周面（見込み面２１ｆ）と外側開口部３２の内周面（見込み面２１ｄ）との間に後述の中間部見付け面２１ｃが形成される。   In the example of FIGS. 1 and 2, the inner peripheral surface (upward surface: prospective surface) of the inner opening 31 in the lower frame portion 22 and the inner peripheral surface (upward surface: prospective surface) of the outer opening 32 are substantially aligned. A step is formed between the inner peripheral surface (downward surface: prospective surface 21f) of the inner opening 31 in the frame portion 21 and the inner peripheral surface (downward surface: prospective surface 21d) of the outer opening 32, and this step exists. Thus, an intermediate portion finding surface 21c described later is formed between the inner peripheral surface (expected surface 21f) of the inner opening 31 of the upper frame portion 21 and the inner peripheral surface (expected surface 21d) of the outer opening 32.

図１、図２ではまた、一方（室内から室外を見たときの右側）の縦枠部２３における内側開口部３１の内周面（見込み面）と外側開口部３２の内周面（見込み面）がほぼ揃えられ、他方の縦枠部２３における内側開口部３１の内周面（見込み面２３ｆ）と外側開口部３２の内周面（見込み面２３ｄ）との間に段差が形成され、段差によって内側開口部３１の内周面と外側開口部３２の内周面との間に中間部見付け面２３ｃが形成されている。   In FIGS. 1 and 2, the inner peripheral surface (expected surface) of the inner opening 31 and the inner peripheral surface (expected surface) of the outer opening 32 in the vertical frame 23 on one side (the right side when viewed from the inside of the room). ) Are substantially aligned, and a step is formed between the inner peripheral surface (expected surface 23f) of the inner opening 31 and the inner peripheral surface (expected surface 23d) of the outer opening 32 in the other vertical frame portion 23. Thus, an intermediate portion finding surface 23 c is formed between the inner peripheral surface of the inner opening 31 and the inner peripheral surface of the outer opening 32.

但し、少なくともいずれかの枠部における内側開口部３１と外側開口部３２の各内周面間に段差が形成されていれば、内側開口部３１と外側開口部３２が互いに異なる立面形状をすることになるため、その他の枠部における内側開口部３１と外側開口部３２の各内周面が揃えられるか、段差が形成されるかは任意である。   However, if a step is formed between the inner peripheral surfaces of the inner opening 31 and the outer opening 32 in at least one of the frame portions, the inner opening 31 and the outer opening 32 have different elevational shapes. Therefore, whether the inner peripheral surfaces of the inner opening 31 and the outer opening 32 in the other frame portions are aligned or a step is formed is arbitrary.

フレーム２は開口部３の上側に位置する上枠部２１と、下側に位置する下枠部２２、及び幅方向両側に位置する縦枠部２３、２３に区分される。これらフレーム２を構成する上枠部２１と下枠部２２、及び縦枠部２３、２３の内、室内側を向く室内側見付け面２１ａの見付け幅と室外側を向く室外側見付け面２１ｂの見付け幅が相違する、少なくともいずれかの枠部の見込み方向中間部に、二重サッシ間に形成される空気層６に面する中間部見付け面２１ｃが形成される。   The frame 2 is divided into an upper frame portion 21 positioned above the opening 3, a lower frame portion 22 positioned on the lower side, and vertical frame portions 23 and 23 positioned on both sides in the width direction. Of the upper frame portion 21 and the lower frame portion 22 and the vertical frame portions 23, 23 constituting the frame 2, the finding width of the indoor-side finding surface 21a facing the indoor side and the outdoor-side finding surface 21b facing the outdoor side are found. An intermediate portion finding surface 21c facing the air layer 6 formed between the double sashes is formed at the prospective intermediate portion of at least one of the frame portions having different widths.

「室内側を向く室内側見付け面の見付け幅と室外側を向く室外側見付け面の見付け幅が相違するいずれかの枠部」は図１、図２の例では上枠部２１と一方の縦枠部２３であるが、下枠部２２の場合もあれば、全枠部の場合もある。室内側見付け面２１ａと室外側見付け面２１ｂ、及び中間部見付け面２１ｃは必ずしも平坦面である必要はない。   "Any frame part in which the finding width of the indoor-side finding surface facing the indoor side and the finding width of the outdoor-side finding face facing the outdoor side are different" is the upper frame part 21 and one of the vertical frames in the example of FIGS. The frame portion 23 may be the lower frame portion 22 or the entire frame portion. The indoor side finding surface 21a, the outdoor side finding surface 21b, and the intermediate portion finding surface 21c are not necessarily flat surfaces.

中間部見付け面２１ｃは前記のように室内側見付け面２１ａの見付け幅と室外側見付け面２１ｂの見付け幅が相違する枠部における内側開口部３１の内周面（見込み面２１ｆ）と外側開口部３２の内周面（見込み面２１ｄ）との間の段差によって形成される。図１、図２の例では上枠部２１における内側開口部３１の内周面（見込み面２１ｆ）と外側開口部３２の内周面（見込み面２１ｄ）との間に形成された段差によって内側開口部３１の内周面と外側開口部３２の内周面をつなぐ中間部見付け面２１ｃが形成される。図１、図２では上枠部２１における内側開口部３１の内周面（見込み面２１ｆ）が外側開口部３２の内周面（見込み面２１ｄ）より下に位置するため、中間部見付け面２１ｃは室外側を向いているが、上枠部２１における内側開口部３１の内周面（見込み面２１ｆ）が外側開口部３２の内周面（見込み面２１ｄ）より上に位置する場合には、中間部見付け面２１ｃは室内側を向く。   As described above, the intermediate portion finding surface 21c has the inner peripheral surface (expected surface 21f) and the outer opening portion of the inner opening 31 in the frame portion where the finding width of the indoor finding surface 21a and the finding width of the outdoor finding surface 21b are different. It is formed by the level | step difference between 32 inner peripheral surfaces (expected surface 21d). In the example of FIGS. 1 and 2, the inner side is formed by a step formed between the inner peripheral surface (expected surface 21 f) of the inner opening 31 in the upper frame portion 21 and the inner peripheral surface (expected surface 21 d) of the outer opening 32. An intermediate portion finding surface 21c that connects the inner peripheral surface of the opening 31 and the inner peripheral surface of the outer opening 32 is formed. In FIG. 1 and FIG. 2, since the inner peripheral surface (expected surface 21f) of the inner opening 31 in the upper frame portion 21 is positioned below the inner peripheral surface (expected surface 21d) of the outer opening 32, the intermediate portion finding surface 21c. Is facing the outdoor side, but when the inner peripheral surface (expected surface 21f) of the inner opening 31 in the upper frame portion 21 is located above the inner peripheral surface (expected surface 21d) of the outer opening 32, The intermediate portion finding surface 21c faces the indoor side.

フレーム２を構成する各枠部２１、２２、２３における内側開口部３１の内周面と、外側開口部３２の内周面にはそれぞれ内側サッシ４のサッシ枠４２と、外側サッシ５のサッシ枠５２が配置され、サッシ枠４２、５２はそれぞれの定着部（アンカー）によって各枠部２１、２２、２３内に定着される。内側開口部３１の内周面と外側開口部３２の内周面の形状は各サッシ枠４２、５２内に収納される障子の形態に応じて決まり、図示するように段差が付く場合と平坦面に形成される場合がある。   A sash frame 42 of the inner sash 4 and a sash frame of the outer sash 5 are respectively provided on the inner peripheral surface of the inner opening 31 and the inner peripheral surface of the outer opening 32 in each of the frame portions 21, 22, and 23 constituting the frame 2. 52 is disposed, and the sash frames 42 and 52 are fixed in the frame portions 21, 22 and 23 by the respective fixing portions (anchors). The shape of the inner peripheral surface of the inner opening 31 and the inner peripheral surface of the outer opening 32 is determined according to the form of the shoji stored in each sash frame 42, 52, and a flat surface with a step as shown in the figure May be formed.

以下では図１、図２の例に基づき、「室内側見付け面の見付け幅と室外側見付け面の見付け幅が相違する枠部」を上枠部２１に代表させて説明する。図１の例では中間部見付け面２１ｃは室外側（外側サッシ５側）を向いているが、前記のように内側開口部３１の内周面が外側開口部３２の内周面より上に位置する場合、あるいは壁パネル１が図１の室内側と室外側を入れ換えた形をした場合には、中間部見付け面２１ｃは室内側（内側サッシ４側）を向くことになる。   Hereinafter, based on the example of FIGS. 1 and 2, the “frame portion in which the finding width of the indoor-side finding surface and the finding width of the outdoor-side finding surface are different” will be described as a representative of the upper frame portion 21. In the example of FIG. 1, the intermediate portion finding surface 21 c faces the outdoor side (outer sash 5 side), but the inner peripheral surface of the inner opening 31 is positioned above the inner peripheral surface of the outer opening 32 as described above. When the wall panel 1 has a shape in which the indoor side and the outdoor side in FIG. 1 are interchanged, the intermediate portion finding surface 21c faces the indoor side (inner sash 4 side).

室内側見付け面２１ａの見付け幅と室外側見付け面２１ｂの見付け幅が相違する枠部（上枠部２１）の空気層６に面する中間部見付け面２１ｃと、その枠部（上枠部２１）の室内側見付け面２１ａ、もしくは室外側見付け面２１ｂとの間には貫通孔２４が貫通して形成される。室内側見付け面の見付け幅と室外側見付け面の見付け幅が相違する枠部は下枠部２２、もしくは縦枠部２３であることもあり、全枠部であることもある。   An intermediate portion finding surface 21c facing the air layer 6 of the frame portion (upper frame portion 21) in which the finding width of the indoor side finding surface 21a and the finding width of the outdoor side finding surface 21b are different, and the frame portion (upper frame portion 21). ) Through-holes 24 are formed so as to penetrate between the indoor-side finding surface 21a and the outdoor-side finding surface 21b. The frame portion in which the finding width of the indoor-side finding surface and the finding width of the outdoor-side finding surface are different may be the lower frame portion 22 or the vertical frame portion 23, or may be the entire frame portion.

図示する例では上枠部２１と一方の縦枠部２３が「室内側見付け面の見付け幅と室外側見付け面の見付け幅が相違する枠部」に該当する。図面では上枠部２１にのみ、貫通孔２４を形成しているが、図２において一方の縦枠部２３の室内側見付け面２３ａと中間部見付け面２３ｃとの間にも貫通孔２４が形成されることがある。中間部見付け面２１ｃ、２３ｃが室内側を向く場合には、貫通孔２４は中間部見付け面２１ｃ、２３ｃと、室外側見付け面２１ｂ、２３ｂとの間に形成されることになる。   In the illustrated example, the upper frame portion 21 and one vertical frame portion 23 correspond to “a frame portion in which the finding width of the indoor-side finding surface and the finding width of the outdoor-side finding surface are different”. Although the through hole 24 is formed only in the upper frame portion 21 in the drawing, the through hole 24 is also formed between the indoor side finding surface 23a and the intermediate portion finding surface 23c of one vertical frame portion 23 in FIG. May be. When the intermediate portion finding surfaces 21c and 23c face the indoor side, the through hole 24 is formed between the intermediate portion finding surfaces 21c and 23c and the outdoor side finding surfaces 21b and 23b.

空気層６を通過して貫通孔２４から壁パネル１の外部に排出される空気は、貫通孔２４が形成された枠部（上枠部２１）以外の枠部（下枠部２２、縦枠部２３）、もしくはその枠部（下枠部２２、縦枠部２３）に保持される少なくともいずれかのサッシの枠であるサッシ枠４２、５２、または前記枠部（下枠部２２、縦枠部２３）とサッシの枠（サッシ枠４２、５２）との間の少なくともいずれかに形成され、室内、もしくは室外に連通する通気口２５から壁パネル１の内部に取り込まれ、空気層６に送り込まれる。   The air that passes through the air layer 6 and is discharged to the outside of the wall panel 1 from the through hole 24 is a frame portion (lower frame portion 22, vertical frame) other than the frame portion (upper frame portion 21) in which the through hole 24 is formed. Part 23), or sash frames 42 and 52 which are frames of at least one sash held by the frame part (lower frame part 22, vertical frame part 23), or the frame part (lower frame part 22, vertical frame). Portion 23) and the sash frame (sash frames 42, 52), which are taken into the wall panel 1 from the vent 25 communicating indoors or outdoors and sent into the air layer 6. It is.

図１、図２の例では内側サッシ４の、上枠４２１と下枠４２２、及び縦枠４２３、４２３からなるサッシ枠４２をフレーム２の内側開口部３１に固定し、各縦枠４２３に１枚の障子４１をそれぞれヒンジ４３を介して内開き式に支持させ、下枠４２２と障子４１の下框４１２との間に、常に開放する空隙（空間）を確保することによりこの空隙を通気口２５として利用している。図１、図２では障子４１の上框４１１と上枠４２１との間、及び縦框４１３と縦枠４２３との間も空隙が形成されるが、各空隙から取り込まれた室内空気はダクト９の先に接続されたファンによる強制吸気により貫通孔２４側へ移動しようとするため、空気層６の下端（下枠部２２）側には下枠４２２と下框４１２との間の空隙（通気口２５）から取り込まれることになる。   In the example of FIGS. 1 and 2, the sash frame 42 composed of the upper frame 421 and the lower frame 422 and the vertical frames 423 and 423 of the inner sash 4 is fixed to the inner opening 31 of the frame 2, and one sash frame 42 is attached to each vertical frame 423. Each of the shojis 41 is supported in an inward-opening manner via the hinges 43, and a space (space) that is always open is secured between the lower frame 422 and the lower collar 412 of the shoji 41, so that the air gaps are opened. 25 is used. In FIG. 1 and FIG. 2, gaps are also formed between the upper collar 411 and the upper frame 421 of the shoji 41 and between the vertical fence 413 and the vertical frame 423, but the indoor air taken in from each gap is duct 9. In order to move to the through-hole 24 side by forced intake by a fan connected to the tip of the air gap, a gap (ventilation) between the lower frame 422 and the lower rod 412 is formed on the lower end (lower frame portion 22) side of the air layer 6. It will be taken in from the mouth 25).

図１、図２ではまた、外側サッシ５の、上枠５２１と下枠５２２、及び縦枠５２３、５２３からなるサッシ枠５２をフレーム２の外側開口部３２に固定し、サッシ枠５２内に障子５１としてのガラスを嵌殺し状態で収納している。この場合、ガラスが直接、サッシ枠５２内に飲み込まれるため、上枠５２１と下枠５２２、及び縦枠５２３、５２３は障子５１の一部としての框が一体化した形状をしている。上枠５２１と下枠５２２、及び縦枠５２３、５２３の内のいずれか一部の枠（上枠５２１と縦枠５２３）にはガラスの収納と取り外しを可能にするための押縁５２４が着脱自在に接続される。   1 and 2, the sash frame 52 including the upper frame 521 and the lower frame 522 and the vertical frames 523 and 523 of the outer sash 5 is fixed to the outer opening 32 of the frame 2, and the obstacle is placed in the sash frame 52. The glass 51 is housed in a fitted state. In this case, since the glass is swallowed directly into the sash frame 52, the upper frame 521, the lower frame 522, and the vertical frames 523, 523 have a shape in which the ridges as a part of the shoji 51 are integrated. One of the upper frame 521, the lower frame 522, and the vertical frames 523, 523 (the upper frame 521 and the vertical frame 523) is detachably provided with a pressing edge 524 for allowing glass to be stored and removed. Connected to.

図１、図２では外側サッシ５のサッシ枠５２を框が一体化した形状の上枠５２１と下枠５２２、及び縦枠５２３、５２３から構成しているが、例えば上枠５２１の一部の空気層６に面する片（見込み片）と室外に面する片（見付け片）に両者間に連通する孔（開口）を形成し、図４−（ｂ）、（ｄ）に示すようにこの孔を排気口として利用することも可能である。その場合、排気口に強制排気のためのファンを配置することが難しいため、排気は自然に行われることになる。同様に下枠５２２、もしくは縦枠５２３の一部の空気層６に面する片（見込み片）と室外に面する片（見付け片）に両者間に連通する孔（開口）を形成し、図４−（ｃ）、（ｄ）に示すようにこの孔を通気口（排気口）２５として利用することも可能である。   1 and 2, the sash frame 52 of the outer sash 5 is composed of an upper frame 521, a lower frame 522, and vertical frames 523 and 523 in which the ridges are integrated. For example, a part of the upper frame 521 A hole (opening) communicating between the air layer 6 (expected piece) and the outdoor facing piece (finding piece) is formed between the two, as shown in FIGS. 4- (b) and (d). It is also possible to use the hole as an exhaust port. In that case, since it is difficult to dispose a fan for forced exhaust at the exhaust port, exhaust is naturally performed. Similarly, a hole (opening) that communicates between the lower frame 522 or a part of the vertical frame 523 facing the air layer 6 (a prospective piece) and a piece facing the outside (a finding piece) are formed. 4- (c), (d), this hole can be used as a vent (exhaust port) 25.

図１の例では貫通孔２４は中間部見付け面２１ｃと、上枠部２１の室内側見付け面２１ａとの間に形成されていることで、壁パネル１の外部としては室内側見付け面２１ａにおいて室内に面するため、貫通孔２４は空気層６を通過した空気を室内に還気するための還気口になる。貫通孔２４を還気口として使用する場合には、上枠部２１の室内側見付け面２１ａに還気用のダクト８、もしくはチャンバー９が接続される。図１では室内側見付け面２１ａに、同一高さに配列する複数枚の壁パネル１の貫通孔２４からの空気を取り込むためのチャンバー９を接続し、チャンバー９にダクト８を接続している。ダクト８には強制的な吸気のためのファンが接続されることもあるが、ファンを使用することなく、空気層６での対流により自然に空気を循環させることもある。   In the example of FIG. 1, the through hole 24 is formed between the intermediate portion finding surface 21 c and the indoor side finding surface 21 a of the upper frame portion 21. Since it faces the room, the through hole 24 serves as a return port for returning the air that has passed through the air layer 6 to the room. When the through hole 24 is used as a return air port, the return air duct 8 or the chamber 9 is connected to the indoor-side finding surface 21 a of the upper frame portion 21. In FIG. 1, a chamber 9 for taking in air from the through holes 24 of a plurality of wall panels 1 arranged at the same height is connected to the indoor-side finding surface 21 a, and a duct 8 is connected to the chamber 9. A fan for forced intake may be connected to the duct 8, but air may be naturally circulated by convection in the air layer 6 without using the fan.

図１に示す断面形状の上枠部２１においては、中間部見付け面２１ｃに連続し、空気層６に面する外側開口部３２の内周面（見込み面２１ｄ）が形成されているため、見込み面２１ｄと室外側見付け面２１ｂとの間を貫通する貫通孔２１ｅを形成することで、その貫通孔２１ｅを上枠部２１における空気層６と室外が連通する排気口として利用することができる。   In the upper frame portion 21 of the cross-sectional shape shown in FIG. 1, the inner peripheral surface (expected surface 21 d) of the outer opening 32 that faces the air layer 6 and is continuous with the intermediate portion finding surface 21 c is formed. By forming the through-hole 21e penetrating between the surface 21d and the outdoor-side finding surface 21b, the through-hole 21e can be used as an exhaust port through which the air layer 6 in the upper frame portion 21 communicates with the outside.

同様に、図２に示す一方の断面形状の縦枠部２３においては、中間部見付け面２３ｃに連続し、空気層６に面する外側開口部３２の内周面（見込み面２３ｄ）が形成されているため、見込み面２３ｄと室外側見付け面２３ｂとの間を貫通する貫通孔２３ｅを形成することで、縦枠部２３に空気層６と室外が連通する排気口を形成することが可能である。   Similarly, in the vertical frame portion 23 having one cross-sectional shape shown in FIG. 2, an inner peripheral surface (a prospective surface 23 d) of the outer opening 32 facing the air layer 6 is formed continuously with the intermediate portion finding surface 23 c. Therefore, by forming the through-hole 23e that passes between the prospective surface 23d and the outdoor-side finding surface 23b, it is possible to form an exhaust port in the vertical frame portion 23 that allows the air layer 6 and the outdoor to communicate with each other. is there.

また図１に示す例では、貫通孔２４が上枠部２１の中間部見付け面２１ｃと室内側見付け面２１ａとの間に形成されているが、フレーム２が室内側と室外側の向きを入れ換えて使用されれば、貫通孔２４は上枠部２１の中間部見付け面２１ｃと室外側見付け面２１ｂとの間に形成されることになる。フレーム２が図１の状態にあるとき、貫通孔２４は壁パネル１の外部としては室内側見付け面２１ａにおいて室内に面するため、貫通孔２４は空気層６を通過した空気を室内に還気するための還気口になる。図１の状態の室内側と室外側を入れ換えてフレーム１を使用したときには、貫通孔２４は空気層６を通過した空気を室外に排出するための排気口になる。   Further, in the example shown in FIG. 1, the through hole 24 is formed between the intermediate portion finding surface 21 c and the indoor side finding surface 21 a of the upper frame portion 21, but the frame 2 is switched between the indoor side and the outdoor side. If used, the through hole 24 is formed between the intermediate portion finding surface 21c of the upper frame portion 21 and the outdoor side finding surface 21b. When the frame 2 is in the state shown in FIG. 1, the through-hole 24 faces the interior of the indoor-side finding surface 21 a as the outside of the wall panel 1, so the through-hole 24 returns the air that has passed through the air layer 6 to the room. Become a return vent to do. When the frame 1 is used by exchanging the indoor side and the outdoor side in the state of FIG. 1, the through hole 24 becomes an exhaust port for discharging the air that has passed through the air layer 6 to the outside of the room.

図４−（ａ）〜（ｄ）は壁パネル１に形成した通気口２５と貫通孔２４、２１ｅとの間における吸気と排気（還気）の形態（パターン）例を示す。（ａ）は図１に示した空気の流れと同じく、フレーム２の下枠部２２と内側サッシ４の下框４１２との間に形成した通気口２５から室内空気を空気層６に取り込み、フレーム２の上枠部２１に形成した貫通孔２４から還気（排気）する場合、（ｂ）は下枠部２２と下框４１２との間の通気口２５から室内空気を空気層６に取り込み、上枠部２１に形成した排気口（貫通孔２１ｅ）、もしくは上枠部２１と外側サッシ５の上框５１１との間に形成した上記排気口から室外へ排気する場合である。   FIGS. 4A to 4D show examples of patterns (patterns) of intake air and exhaust air (return air) between the air vent 25 formed in the wall panel 1 and the through holes 24 and 21e. (A) is the same as the air flow shown in FIG. 1, in which room air is taken into the air layer 6 from a vent 25 formed between the lower frame portion 22 of the frame 2 and the lower collar 412 of the inner sash 4. 2 when returning air (exhaust) from the through-hole 24 formed in the upper frame portion 21, (b) takes room air into the air layer 6 from the vent 25 between the lower frame portion 22 and the lower rod 412, In this case, the air is exhausted from the exhaust port (through hole 21e) formed in the upper frame portion 21 or the above-described exhaust port formed between the upper frame portion 21 and the upper collar 511 of the outer sash 5 to the outside.

図４−（ｃ）はフレーム２の下枠部２２に形成した通気口２５としての孔（開口）から室外空気を空気層６に取り込み、フレーム２の上枠部２１に形成した貫通孔２４から還気（排気）する場合、（ｄ）はフレーム２の下枠部２２の通気口２５から室外空気を空気層６に取り込み、フレーム２の上枠部２１に形成した排気口（貫通孔２１ｅ）、もしくは上枠部２１と外側サッシ５の上框５１１との間に形成した上記排気口から排気する場合である。なお、（ａ）〜（ｄ）のいずれの場合も、矢印で示すように空気の流れ、すなわち空気の取り込みと排気の位置が逆になることもある。   FIG. 4C shows that outdoor air is taken into the air layer 6 from a hole (opening) as a vent 25 formed in the lower frame portion 22 of the frame 2, and from the through hole 24 formed in the upper frame portion 21 of the frame 2. When returning air (exhaust), (d) is an exhaust port (through hole 21e) formed in the upper frame portion 21 of the frame 2 by taking outdoor air into the air layer 6 from the vent 25 of the lower frame portion 22 of the frame 2. Alternatively, the air is exhausted from the exhaust port formed between the upper frame portion 21 and the upper collar 511 of the outer sash 5. In any of the cases (a) to (d), as indicated by arrows, the air flow, that is, the intake and exhaust positions may be reversed.

図５は前記のように図１、図２に示す壁パネル１のフレーム２における内側開口部３１と外側開口部３２と、それぞれの内周面の形状に対応した形状の内側サッシ４及び外側サッシ５との関係を示している。ここに示すように図１、図２の例ではフレーム２の内側開口部３１と外側開口部３２の下枠部２２と一方の縦枠部２３における内周面は揃えられ、上枠部２１と他方の縦枠部２３における内周面に段差が形成されている。   FIG. 5 shows the inner opening 31 and the outer opening 32 in the frame 2 of the wall panel 1 shown in FIGS. 1 and 2, and the inner sash 4 and the outer sash having shapes corresponding to the shapes of the respective inner peripheral surfaces. 5 is shown. As shown here, in the example of FIGS. 1 and 2, the inner peripheral surface of the inner opening 31 and the outer opening 32 of the frame 2 and the inner peripheral surface of one vertical frame 23 are aligned, and the upper frame 21 A step is formed on the inner peripheral surface of the other vertical frame portion 23.

図６は図１、図２に示す同一の壁パネル１を建物の梁、もしくはスラブ等に支持させながら、水平方向と鉛直方向に配列させた外壁の外観を示す。同一の壁パネル１はフレーム２の開口部３に対する外側開口部３２（外側サッシ５）の配置と寸法が同一であることを言う。図６に示す壁パネル１の配列例では各壁パネル２のフレーム２に対する外側サッシ５の寸法と位置が統一されているため、同一の壁パネル１が整然と配列している外観になる。   FIG. 6 shows the appearance of the outer wall in which the same wall panel 1 shown in FIGS. 1 and 2 is arranged in a horizontal direction and a vertical direction while being supported by a beam or slab of a building. The same wall panel 1 means that the arrangement and dimensions of the outer opening 32 (outer sash 5) with respect to the opening 3 of the frame 2 are the same. In the arrangement example of the wall panels 1 shown in FIG. 6, the size and position of the outer sash 5 with respect to the frame 2 of each wall panel 2 are unified, so that the same wall panel 1 is arranged in an orderly manner.

図７はフレーム２の開口部３に対する外側開口部３２（外側サッシ５）の配置と寸法が壁パネル１毎に異なり、異なる外観を有する複数枚の壁パネル１を建物の梁、もしくはスラブ等に支持させながら、水平方向と鉛直方向に配列させた外壁の外観を示す。この場合、各壁パネル２のフレーム２に対する外側サッシ５の寸法と位置が統一されていないため、外側サッシ５、あるいはフレーム２の開口部３が不規則に配列している外観になる。   In FIG. 7, the arrangement and dimensions of the outer opening 32 (outer sash 5) with respect to the opening 3 of the frame 2 are different for each wall panel 1, and a plurality of wall panels 1 having different appearances are used as building beams or slabs. The external appearance of the outer wall arranged in the horizontal and vertical directions while being supported is shown. In this case, since the dimension and position of the outer sash 5 with respect to the frame 2 of each wall panel 2 are not unified, the outer sash 5 or the openings 3 of the frame 2 are irregularly arranged.
