Description

本発明は、アルミ型材と木材とを組み合わせて構成される複合障子の框構造に関する。   The present invention relates to a saddle structure of a composite shoji configured by combining an aluminum mold and wood.

建物の窓開口部等に設置されるサッシの断熱性を高める技術として、障子の四周を構成する框材を、アルミ型材からなる屋外側框材と木材からなる屋内側框材とを組み合わせて構成した、いわゆる複合障子が公知である。かかる複合障子は、例えば特許文献１、２、３等に開示されている。また、特許文献４等には、アルミ型材からなる屋外側框材と木材からなる屋内側框材との間に合成樹脂製の中間材を介在させて、断熱性をさらに向上させた複合障子が提案されている。   As a technology to improve the thermal insulation of sashes installed in the window openings of buildings, etc., the fences that make up the four sides of the shoji are combined with outdoor side fences made of aluminum molds and indoor side fences made of wood So-called compound shojis are known. Such a composite shoji is disclosed in, for example, Patent Documents 1, 2, 3, and the like. Further, in Patent Document 4 and the like, there is a composite shoji that further improves the heat insulating property by interposing a synthetic resin intermediate material between an outdoor side material made of aluminum and an indoor side material made of wood. Proposed.

上記のような複合障子においては、アルミ型材と木材、あるいは樹脂製の中間材を含むこれらの異素材同士を、合理的な断面の框構造によって確実に結合する必要がある。さらに、それら部材の結合においては、とくに屋内側からの外観にビスの頭部などが現れないような意匠的配慮も要求される。   In the composite shoji as described above, it is necessary to securely bond these different materials including an aluminum mold and wood or an intermediate material made of resin with a rational cross-sectional ridge structure. Furthermore, in the coupling of these members, design considerations are required so that the head of the screw does not appear on the exterior from the indoor side.

特許文献１記載の複合障子は、アルミ型材からなる屋外側框材に形成した凹部に、木材からなる屋内側框材に形成した凸部を、両框材の長さ方向全体にわたって通し込み状に嵌合させ、上下左右の屋内側框材を枠組みした後、その四隅を相互にビス止めする框構造を採用している。   In the composite shoji described in Patent Document 1, the concave portion formed on the outdoor side fence made of aluminum mold material has the convex part formed on the indoor side fence made of wood penetrated over the entire length direction of the both sides. After the frame is fitted and framed on the upper, lower, left, and right indoor side frame material, the frame structure is adopted in which the four corners are screwed together.

特許文献２記載の複合障子は、アルミ型材からなる屋外側框材に形成した溝部に、木材からなる屋内側框材に取り付けた樹脂製の係止ファスナーを挿入し、この係止ファスナーを回動させて、その張出部分を溝部内に係止させて固定する框構造を採用している。   In the composite shoji described in Patent Document 2, a resin-made locking fastener attached to an indoor-side frame made of wood is inserted into a groove formed in an outdoor-side frame made of an aluminum mold, and the locking fastener is rotated. Thus, a hook structure is employed in which the protruding portion is locked and fixed in the groove.

特許文献３記載の複合障子は、アルミ型材からなる屋外側框材に一対のアタッチメントを取り付け、これらのアタッチメントの突片を屋内側に突出させて係合部となし、この係合部に、木材からなる屋内側框材に形成した凸部を、両框材の長さ方向全体にわたって通し込み状に係合させる框構造を採用している。   In the composite shoji described in Patent Document 3, a pair of attachments are attached to an outdoor side fence made of an aluminum mold, and the protruding pieces of these attachments are projected into the indoor side to form an engagement portion. The ridge structure is employed in which the convex portions formed on the indoor side lining material made of are engaged in a penetrating manner over the entire length direction of both lining materials.

特許文献４記載の複合障子は、まず、木材からなる屋内側框材に対して樹脂製の中間材をビス止めし、樹脂製の中間材に形成した溝状の係止部に、アルミ型材からなる屋外側框材に形成した係止部を、両框材の長さ方向全体にわたって通し込み状に嵌合させる框構造を採用している。

上記のような複合障子のうち特許文献１、３、４記載の複合障子は、アルミ型材からなる屋外側框材と木材からなる屋内側框材とが互いに係合し合う断面形状に加工され、両框材の略全長にわたって通し込み状に結合されている。したがって、サッシの建込み工事に先立って両框材を予め結合しておく必要があり、施工上の制約を受けるという不便がある。   Among the composite shojis as described above, the composite shojis described in Patent Documents 1, 3, and 4 are processed into a cross-sectional shape in which an outdoor side eaves made of an aluminum mold material and an indoor side eaves made of wood are engaged with each other, It is connected in a penetrating manner over substantially the entire length of both brazing materials. Therefore, it is necessary to join both the brazing materials in advance prior to the sash erection work, and there is an inconvenience that the construction is restricted.

また、アルミ型材と木材という、強度や耐久性の異なる素材を組み合わせて構成された複合障子においては、長期間使用するうちに、アルミ型材に比して強度や耐久性に劣る木材が、例えば伸縮や乾燥によるひび割れ、屋内の湿気による腐食、傷や汚れ、といった劣化現象をアルミ型材よりも早期に生じやすく、その結果、木材からなる屋内側框材を取り替える必要に迫られることも生じる。このような場合、屋外側框材と屋内側框材とを通し込みによって結合した特許文献１、３、４記載の複合障子では、障子全体を一旦、サッシ枠から完全に取り外さなければ屋内側框材の交換ができないという不便もある。   Also, in composite shojis made by combining materials with different strengths and durability, such as aluminum molds and wood, wood that is inferior in strength and durability compared to aluminum molds, for example, expands and contracts over time. Deterioration phenomena such as cracks due to dryness, corrosion due to moisture in the interior, scratches and dirt are likely to occur earlier than aluminum molds, and as a result, it is necessary to replace the indoor side brazing material made of wood. In such a case, in the composite shoji described in Patent Documents 1, 3, and 4 in which the outdoor side eaves and the indoor side eaves are joined by passing through, the indoor side eaves must be removed once the entire shoji is not completely removed from the sash frame. There is also the inconvenience that the material cannot be replaced.

特許文献２記載の複合障子は、ガラスパネルを挟み込んでいる屋内側の押縁を取り外して屋内側框材の側端部を開口させ、この開口からスパナ等の工具を操作して樹脂製の係止ファスナーを回動操作することにより、障子をサッシ枠内に建て込んだままで屋内側框材を屋外側框材から取り外すことができるように構成されている。しかし、この場合でも、上下左右それぞれの屋内側框材に取り付けられた複数個の係止ファスナーをひとつずつ回動させなければならず、取り外し、取り付けともに面倒な作業が要求される。   In the compound shoji described in Patent Document 2, the indoor side edge that sandwiches the glass panel is removed to open the side end of the indoor side wall material, and a tool such as a spanner is operated from this opening to lock the resin. By rotating the fastener, the indoor side frame can be removed from the outdoor side frame while the shoji is built in the sash frame. However, even in this case, it is necessary to rotate a plurality of locking fasteners attached to the indoor side lining materials of the top, bottom, left, and right, one by one, and both removal and attachment are troublesome.

かかる事情に鑑みて、本出願人らは、複合障子をサッシ枠内に建て込んだままでも、屋内側框材を屋外側框材に対して容易かつ確実に着脱しうるような新規の框構造を研究してきた。そして、この研究により、屋外側框材の屋内面に、その長さ方向にわたる凹部を断面一様に形成し、この凹部内にリップ付きの溝形断面を有する短尺の受けピースを複数個、適宜間隔で取り付ける一方、屋内側框材の屋外面には、上記受けピースのリップに係合しうる張出部を備えた係合ピースを、上記受けピースと対応する位置に複数個取り付け、この屋内側框材を屋外側框材の屋内面に当てがって長さ方向に摺動させることにより、上記係合ピースを受けピースに嵌合させて屋内側框材を屋外側框材に着脱自在に結合する框構造を完成させた（特願２００５−１８３３５１号）。   In view of such circumstances, the present applicants have proposed a new cage structure that can easily and reliably attach and detach the indoor side fence to the outdoor side fence even when the composite shoji is built in the sash frame. Have studied. And by this research, a concave portion extending in the length direction is formed uniformly on the indoor surface of the outdoor side wall material, and a plurality of short receiving pieces having a groove-shaped cross section with a lip are appropriately formed in the concave portion. On the other hand, on the outdoor surface of the indoor side wall material, a plurality of engaging pieces having a protruding portion that can engage with the lip of the receiving piece are attached to the outdoor surface of the indoor side fence material at positions corresponding to the receiving piece. The inner frame is placed on the indoor surface of the outdoor frame and slid in the length direction so that the indoor piece can be attached to and detached from the outdoor frame by fitting the engagement piece to the receiving piece. The heel structure that is bonded to the slab was completed (Japanese Patent Application No. 2005-183351).

しかし、上記の框構造においては、屋外側框材の屋内面に設けた凹部と屋内側框材との間に、框材の長さ方向に連続する溝空間が形成されることとなり、この溝空間内に入り込んだ空気中の水分が屋外側框材の屋内面に結露して、特に縦框においては、その結露水が凹部に沿って流下し、縦框の下部に溜まって、木材からなる屋内側框材の下端木口面を濡らす場合があることが確認された。このような現象によって屋内側框材の木口面が濡れると、木材が腐食し易くなるので好ましくない。そこで、本発明は、上記框構造をさらに改良し、屋外側框材と屋内側框材との間に生じる結露水の排水対策を講じて、屋内側框材が濡れるのを万全に防止することを解決課題としている。   However, in the above-described cage structure, a groove space continuous in the length direction of the fence material is formed between the concave portion provided on the indoor surface of the outdoor tile material and the indoor side fence material. Moisture in the air that has entered the space condenses on the indoor surface of the outdoor side wall material, and in particular, in the vertical wall, the condensed water flows down along the recesses and collects in the lower part of the vertical wall and is made of wood. It has been confirmed that the lower end of the indoor side wood may get wet. Such a phenomenon is not preferable because the lumber surface of the indoor side timber gets wet, because the wood tends to corrode. Therefore, the present invention further improves the above-described dredging structure and takes measures against drainage of condensed water generated between the outdoor dredging material and the indoor dredging material to prevent the indoor dredging material from getting wet. Is a solution issue.

上記した目的を達成するため、本発明の框構造は、アルミ型材、又はアルミ型材と樹脂材との複合材からなる屋外側框材の屋内面に、該屋外側框材の長さ方向にわたる凹部を断面一様に形成し、この凹部内にリップ付きの溝形断面を有する短尺の受けピースを複数個、適宜間隔で取り付ける一方、木材からなる屋内側框材の屋外面に、上記受けピースのリップに係合しうる張出部を備えた係合ピースを、上記受けピースと対応する位置に複数個取り付け、この屋内側框材を屋外側框材の屋内面に当てがって長さ方向に摺動させることにより、上記係合ピースが受けピースに嵌合されて、屋内側框材が屋外側框材に着脱自在に結合されるように構成した框構造において、少なくとも縦方向の框材については、受けピースと係合ピースとの嵌合箇所に隙間を設け、上記凹部内の溝空間を縦方向に連通させるとともに、その下端部に底蓋部材を取り付けて、この底蓋部材に排水孔を貫通形成したことを特徴とする。   In order to achieve the above-described object, the eaves structure of the present invention has a concave portion extending in the length direction of the outdoor side eaves on the indoor surface of the outdoor eaves made of an aluminum mold material or a composite material of an aluminum mold material and a resin material. A plurality of short receiving pieces having a groove-shaped cross section with a lip are attached at appropriate intervals in the recess, and the receiving piece of the receiving piece is placed on the outdoor surface of the indoor side frame made of wood. A plurality of engaging pieces having overhanging parts that can engage with the lip are attached at positions corresponding to the receiving pieces, and the indoor side wall material is applied to the indoor surface of the outdoor side wall material in the length direction. In the eaves structure in which the engagement piece is fitted to the receiving piece and the indoor side eaves are detachably coupled to the outdoor side eaves, at least the vertical eaves For the fitting part between the receiving piece and the engaging piece In a gap, with communicating the groove space in the recess in the longitudinal direction, by attaching a bottom cover member at its lower end, characterized by being formed through a drainage hole in the bottom cover.

上述のように構成される本発明の框構造によれば、短尺の受けピースと、これに対応する係合ピースとの嵌合により屋外側框材と屋内側框材とが結合される。したがって、従来の複合障子のように、屋外側框材と屋内側框材とを、それらの略全長にわたって通し込み状に係合あるいは嵌合させる必要がなく、屋内側框材を受けピースの長さ相当分だけ摺動させるという簡単な操作で屋内側框材を取り付けることができる。障子をサッシ枠内に建て込んだままでも屋内側框材の着脱が可能になるので、サッシの建込み作業や屋内側框材の交換も容易になる。   According to the eaves structure of the present invention configured as described above, the outdoor eaves and the indoor eaves are coupled by fitting the short receiving piece and the corresponding engagement piece. Therefore, unlike the conventional composite shoji, there is no need to engage or fit the outdoor side fence and the indoor side fence in a penetrating manner over their entire length, and the length of the receiving piece of the indoor side fence is increased. The indoor side wall material can be attached with a simple operation of sliding by a considerable amount. Even if the shoji is installed in the sash frame, it is possible to attach and detach the indoor frame material, so it is easy to install the sash and replace the indoor frame material.

そして、上記受けピース及び係合ピースが納められる凹部内の溝空間が、係合ピース及び受けピースによって分断されないように、受けピースと係合ピースとの嵌合箇所に隙間を設けている。これにより、凹部内の溝空間が長さ方向に連通し、縦方向の框材については、その中間部に生じた結露水を凹部の下端部まで流下させることができる。流下した結露水は、凹部の下端部に取り付けられた底蓋部材の排水孔から排出されて、下枠の表面又は内部を経由し、屋外に排出される。こうして、縦框の凹部内に万一、結露が生じた場合でも、その結露水を円滑に排出して、屋内側框材の下端部が濡れるのを防止することができる。   And the clearance gap is provided in the fitting location of a receiving piece and an engaging piece so that the groove space in the recessed part in which the said receiving piece and an engaging piece are stored is not parted by the engaging piece and the receiving piece. Thereby, the groove space in a recessed part is connected to the length direction, and about the vertical brazing material, the dew condensation water produced in the intermediate part can be flowed down to the lower end part of a recessed part. The condensed water that has flowed down is discharged from the drain hole of the bottom cover member attached to the lower end of the recess, and is discharged to the outside via the surface or the inside of the lower frame. In this way, even if dew condensation occurs in the concave portion of the vertical wall, the dew condensation water can be smoothly discharged to prevent the lower end portion of the indoor side wall material from getting wet.

以下、本発明の実施の形態について図を参照して説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

A screen door 36 is attached to the outdoor side of the shoji 1. In the present invention, the detailed cross-sectional shape of the sash frame 3 is not particularly limited.

外障子１及び内障子２の四周を構成する框材は、アルミ型材４１と樹脂型材４２との複合材からなる屋外側框材４（４ａ〜４ｈ）と、その屋内側に取り付けられた木材からなる屋内側框材５（５ａ〜５ｈ）とを組み合わせて構成されている。屋外側框材４を構成するアルミ型材４１と樹脂型材４２とは、双方に形成した係合部を、上下左右の各屋外側框材４の略全長にわたって通し込み状に係合させることにより予め一体化されている。そして、これらアルミ型材４１と樹脂型材４２との間に、複層ガラスからなるパネル面材４３が嵌め込まれている。   The saddle material that constitutes the four circumferences of the external shoji 1 and the internal shoji 2 is composed of an outdoor side saddle material 4 (4a to 4h) made of a composite material of an aluminum mold material 41 and a resin mold material 42, and wood attached to the indoor side. It is comprised combining the indoor side wall material 5 (5a-5h) which becomes. The aluminum mold 41 and the resin mold 42 constituting the outdoor side collar 4 are preliminarily engaged by engaging the engaging portions formed on both sides of the outdoor side collar 4 substantially vertically over the entire length. It is integrated. And between these aluminum mold material 41 and the resin mold material 42, the panel surface material 43 which consists of multilayer glass is engage | inserted.

屋外側框材４と屋内側框材５とは、受けピース６と係合ピース７との係合によって着脱自在に結合される。例示の形態では、上下左右の屋外側框材４を構成する樹脂型材４２の屋内面に、各屋外側框材４の長さ方向にわたって、見付幅が１０〜２０ｍｍ程度の凹部４４を断面一様に形成し、この凹部４４内に、屋内側框材５を結合させるための受けピース６を複数個、適宜間隔で取り付けている。   The outdoor side collar 4 and the indoor side collar 5 are detachably coupled by the engagement of the receiving piece 6 and the engagement piece 7. In the illustrated embodiment, a concave portion 44 having a width of about 10 to 20 mm is formed on the indoor surface of the resin mold member 42 constituting the outdoor side roofing material 4 on the top, bottom, left, and right. In this concave portion 44, a plurality of receiving pieces 6 for coupling the indoor side cage 5 are attached at appropriate intervals.

図３は、受けピース６と、これに結合される係合ピース７の構成を示す斜視説明図であり、図４は、上記両ピース６、７の結合状態を框材４、５の断面方向から見て示す説明図である。受けピース６は、長さが２０〜４０ｍｍ程度で、幅が上記凹部４４に納まる寸法に形成された、薄くて平らな矩形状の基板６１と、この基板６１の長手方向中間部に突設された一対のリップ６２、６２を有する樹脂製の短尺部材である。リップ６２は、基板６１の両縁から屋内側に向かって脚部を立ち上げ、その先端が断面略Ｌ字形に折曲されて互いに向かい合っている。リップ６２の脚部の立ち上がり高さは、上記凹部４４の深さと略合致している。向かい合うリップ６２、６２同士の間隔は、中央部よりも端部のほうがやや拡がっている。リップ６２の長さは１０〜３０ｍｍ程度に設定されている。この受けピース６は、基板６１に形成されたビス孔６３を利用して、屋外側框材４の凹部４４の底面にビス固定される。   FIG. 3 is an explanatory perspective view showing the structure of the receiving piece 6 and the engaging piece 7 coupled thereto, and FIG. 4 shows the coupled state of the two pieces 6 and 7 in the cross-sectional direction of the saddle members 4 and 5. FIG. The receiving piece 6 has a length of about 20 to 40 mm and a width and a dimension that can be accommodated in the recess 44, and is formed in a thin and flat rectangular substrate 61, and projects in the middle in the longitudinal direction of the substrate 61. A short member made of resin having a pair of lips 62, 62. The lip 62 has its legs raised from both edges of the substrate 61 toward the indoor side, and its tip is bent into a substantially L-shaped cross section and faces each other. The rising height of the leg portion of the lip 62 substantially matches the depth of the concave portion 44. The distance between the facing lips 62, 62 is slightly wider at the end than at the center. The length of the lip 62 is set to about 10 to 30 mm. The receiving piece 6 is screw-fixed to the bottom surface of the concave portion 44 of the outdoor side saddle member 4 using a screw hole 63 formed in the substrate 61.

一方、屋内側框材５には、上記受けピース６のリップ６２に係合しうる係合ピース７が、受けピース６と対応する位置にそれぞれ取り付けられる。係合ピース７は、略円板状の張出部７１と、この張出部７１よりも細径の軸部７２とを備え、中央に形成された軸孔７３を利用して、屋内側框材５の屋外面にビス固定される。張出部７１の径は上記受けピース６のリップ６２の両脚部間に嵌まり込む大きさに設定され、張出部７１の厚さはリップ６２の脚部の立ち上がり高さよりもやや小さく設定されている。また、軸部７２の径はリップ６２同士の先端間隔よりもやや小さく、軸部７２の高さはリップ６２の先端の厚みと略合致している。   On the other hand, an engagement piece 7 that can be engaged with the lip 62 of the receiving piece 6 is attached to the indoor side frame 5 at a position corresponding to the receiving piece 6. The engagement piece 7 includes a substantially disc-shaped overhanging portion 71 and a shaft portion 72 having a diameter smaller than that of the overhanging portion 71. Screws are fixed to the outdoor surface of the material 5. The diameter of the overhanging portion 71 is set to a size that fits between both leg portions of the lip 62 of the receiving piece 6, and the thickness of the overhanging portion 71 is set slightly smaller than the rising height of the leg portion of the lip 62. ing. Further, the diameter of the shaft portion 72 is slightly smaller than the distance between the tips of the lips 62, and the height of the shaft portion 72 substantially matches the thickness of the tip of the lip 62.

上記のような受けピース６を取り付けた屋外側框材４の屋内面に、上記のような係合ピース７を取り付けた屋内側框材５を当てがって、両框材４、５を長さ方向に少しずらした状態で係合ピース７の張出部７１を屋外側框材４の凹部４４内に挿し込み、屋内側框材５を屋外側框材４に対して適正に重なる位置まで摺動させると、係合ピース７の張出部７１が受けピース６のリップ６２間に嵌合されて、屋内側框材５が屋外側框材４に結合される。屋内側框材５を逆方向、または同じ方向にさらに摺動させると、係合ピース７と受けピース６との嵌合が解けて、屋内側框材５を屋外側框材４から離脱させることができる。このような框構造によれば、屋内側框材５を長さ方向に沿って数ｃｍ摺動させるだけで、屋内側框材５を簡単に、かつ確実に着脱することができる。   The indoor side frame 5 attached with the engagement piece 7 as described above is applied to the indoor surface of the outdoor side frame 4 attached with the receiving piece 6 as described above. The protruding portion 71 of the engagement piece 7 is inserted into the recessed portion 44 of the outdoor side roofing material 4 with a slight shift in the vertical direction, and the indoor side roofing material 5 is properly overlapped with the outdoor side roofing material 4. When sliding, the projecting portion 71 of the engagement piece 7 is fitted between the lips 62 of the receiving piece 6, and the indoor side frame 5 is coupled to the outdoor side frame 4. When the indoor side frame 5 is further slid in the reverse direction or the same direction, the engagement piece 7 and the receiving piece 6 are unfitted and the indoor side frame 5 is separated from the outdoor side frame 4. Can do. According to such a saddle structure, the indoor saddle member 5 can be easily and reliably attached and detached simply by sliding the indoor saddle member 5 several centimeters along the length direction.

さらに、例示の形態においては、屋内側框材５を屋外側框材４の屋内面に沿って摺動させるときの操作を容易にするために、屋外側框材４には屋内側に突出して長さ方向に延びる断面一様の突条４５を１〜２本程度形成する一方、屋内側框材５の屋外面には上記突条４５に合致する溝条５１を断面一様に形成している。これにより、屋外側框材４に当てがった屋内側框材５を長さ方向に摺動させるときの横ブレを防いで着脱操作を容易にすることができる。   Furthermore, in the illustrated embodiment, in order to facilitate the operation when sliding the indoor side anchor 5 along the indoor surface of the outdoor side anchor 4, the outdoor side anchor 4 protrudes indoors. About one or two ridges 45 with a uniform cross section extending in the length direction are formed, while grooves 51 that match the ridges 45 are formed on the outdoor surface of the indoor side roofing material 5 with a uniform cross section. Yes. Thereby, it is possible to prevent the lateral blur when sliding the indoor side eaves 5 applied to the outdoor side eaves 4 in the length direction, thereby facilitating the attachment / detachment operation.

図１、２に示した引き違い式のサッシについて、サッシ枠３内に建て込まれた状態の屋外側框材４に屋内側框材５を取り付ける際の具体的な手順を図５〜１２に示す。各図には屋内側から見たサッシを簡略化して取付手順を示した案内図と、当該手順において取り付けられる屋外側框材４及び屋内側框材５の要部断面斜視図とを並べて示す。   1 and 2, the specific procedure for attaching the indoor side frame 5 to the outdoor side frame 4 built in the sash frame 3 is shown in FIGS. Show. In each figure, a guide diagram showing the installation procedure by simplifying the sash viewed from the indoor side, and a cross-sectional perspective view of a main part of the outdoor side roofing material 4 and the indoor side roofing material 5 attached in the procedure are shown side by side.

まず、図５のように外障子１と内障子２とを逆に引き違わせて、外障子１の召合せ部を右側に引き出す。そして、この召合せ部の屋外側框材４ａに屋内側框材５ａを取り付ける。外障子１の召合せ部にはクレセント錠の受け金具８１が取り付けられるため、屋内側框材５ａは、この受け金具８１を間に挟んで上下に分割されている。この召合せ部は、閉鎖時には内障子２の召合せ部に隠れて見えなくなるので、屋内側框材５ａは屋外側框材４ａに対して屋内側からビス固定される。   First, as shown in FIG. 5, the shoji 1 and the shoji 2 are reversed and the summing unit of the shoji 1 is pulled out to the right. And the indoor side collar 5a is attached to the outdoor side collar 4a of this summoning part. Since the crescent lock receiving metal fitting 81 is attached to the summoning portion of the external shoji 1, the indoor side casing 5a is divided vertically with the receiving metal fitting 81 interposed therebetween. Since this summoning portion is hidden behind the summoning portion of the shoji 2 when it is closed, the indoor side roofing material 5a is screw-fixed from the indoor side to the outdoor side roofing material 4a.

次いで図６〜７のように外障子１及び内障子２を閉め、外障子１の下框及び上框に屋内側框材５ｂ、５ｃを取り付ける。ここでの取り付けは、屋外側框材４ｂ、４ｃに当てがった屋内側框材５ｂ、５ｃを、それぞれ戸先側（左側）から召合せ側（右側）へと摺動させて、先に取り付けた召合せ部の屋内側框材５ａに突き当てつつ、受けピース６に係合ピース７を嵌め込む。   Next, as shown in FIGS. 6 to 7, the shoji 1 and the inner shoji 2 are closed, and the indoor side covering materials 5 b and 5 c are attached to the lower arm and the upper arm of the shoji 1. The installation is performed by sliding the indoor side fences 5b and 5c applied to the outdoor side fences 4b and 4c from the door side (left side) to the calling side (right side), respectively. The engaging piece 7 is fitted into the receiving piece 6 while abutting against the indoor side cage 5a of the attached summoning section.

次いで、図８のように、外障子１の左戸先に屋内側框材５ｄを取り付ける。ここでの取り付けは、屋外側框材４ｄに当てがった屋内側框材５ｄを上から下へ摺動させて、受けピース６に係合ピース７を嵌め込む。通常のサッシは、障子の上端とサッシ枠３との間に若干の隙間が設けられるので、サッシ枠３の枠内でも、このような取付操作が可能である。   Next, as shown in FIG. 8, the indoor side roofing material 5 d is attached to the left door of the shoji 1. In this attachment, the indoor side frame 5d applied to the outdoor side frame 4d is slid from top to bottom, and the engagement piece 7 is fitted into the receiving piece 6. Since a normal sash is provided with a slight gap between the upper end of the shoji and the sash frame 3, such a mounting operation is possible even within the frame of the sash frame 3.

次いで、図９のように、内障子２の召合せ部に屋内側框材５ｅを取り付ける。ここでの取り付けも、屋外側框材４ｅに当てがった屋内側框材５ｅを上から下へ摺動させて、受けピース６に係合ピース７を嵌め込む。さらに、召合せ部の左側見付面にも化粧木材５２を取り付ける。内障子２の召合せ部にはクレセント錠の掛け金具８２が取り付けられるため、化粧木材５２には掛け金具８２の位置及び形状に合わせた切欠部５３が形成されている。   Next, as shown in FIG. 9, the indoor side covering material 5 e is attached to the summoning part of the inner shoji 2. Also in this mounting, the engagement piece 7 is fitted into the receiving piece 6 by sliding the indoor frame 5e applied to the outdoor frame 4e from top to bottom. Furthermore, the decorative wood 52 is also attached to the left side of the summoning section. Since a hanging bracket 82 of a crescent lock is attached to the summoning portion of the inner shoji 2, a cutout portion 53 is formed in the decorative wood 52 according to the position and shape of the hanging bracket 82.

次いで図１０〜１１のように、内障子２の下框及び上框に屋内側框材５ｆ、５ｇを取り付ける。ここでの取り付けは、屋外側框材４ｆ、４ｇに当てがった屋内側框材５ｆ、５ｇを、それぞれ戸先側（右側）から召合せ側（左側）へと摺動させて、先に取り付けた召合せ部の屋内側框材５ｅに突き当てつつ、受けピース６に係合ピース７を嵌め込む。   Next, as shown in FIGS. 10 to 11, the indoor side covering materials 5 f and 5 g are attached to the lower and upper heels of the inner shoji 2. The installation is performed by sliding the indoor side fences 5f and 5g applied to the outdoor side fences 4f and 4g from the door side (right side) to the calling side (left side), respectively. The engaging piece 7 is fitted into the receiving piece 6 while abutting against the indoor side cage 5e of the attached summoning section.

次いで、図１２のように、内障子２の右戸先に屋内側框材５ｈを取り付ける。ここでの取り付けは、図８に示した外障子１の左戸先の取り付けと同様である。   Next, as shown in FIG. 12, the indoor side roofing material 5 h is attached to the right door tip of the inner shoji 2. The attachment here is the same as the attachment of the left door tip of the shoji 1 shown in FIG.

このように、本発明の框構造によれば、外障子１及び内障子２をサッシ枠３内に建て込んだ状態でも、屋内側框材５を屋外側框材４の見付面に当てがって数センチ摺動させるだけで、屋内側框材５に取り付けた係合ピース７を屋外側框材４に取り付けた受けピース６に嵌め込んで結合することができる。また、逆手順による屋内側框材５の分離解体も容易である。屋内側框材５の着脱に際しては、パネル面材４３の着脱は不要である。また、屋内側から見える部分にビス頭が露出してしまうこともないので、美麗な外観意匠も得られる。   As described above, according to the cage structure of the present invention, the indoor cage 5 is applied to the surface of the outdoor cage 4 even in the state in which the outer shoji 1 and the inner shoji 2 are built in the sash frame 3. Therefore, the engagement piece 7 attached to the indoor side roofing material 5 can be fitted into and joined to the receiving piece 6 attached to the outdoor side roofing material 4 only by sliding a few centimeters. In addition, separation and disassembly of the indoor side roofing material 5 by the reverse procedure is easy. When the indoor side wall material 5 is attached / detached, the panel face material 43 need not be attached / detached. In addition, since the screw head is not exposed in the portion visible from the indoor side, a beautiful appearance design can be obtained.

上記のような受けピース６と係合ピース７とを結合させる框構造は、樹脂型材４２を介在させずに、アルミ型材４１のみからなる屋外側框材４と木材からなる屋内側框材５とを結合させる構成にも摘要可能であるが、例示形態では、アルミ型材４１と木材との間に木材と同程度の熱伝導率を有する樹脂型材４２を挟み込んで、アルミ型材４２と木材とを直接、接触させないように構成している。さらに、アルミ型材４２と木材とを結合する受けピース６及び係合ピース７も樹脂により形成している。このような框構造においては、結露は通常、熱伝導率の高いアルミ型材の表面にのみ生じるが、屋内外の気象条件やサッシの使用状態等によっては、アルミ型材４１に接触している樹脂型材４２も多少冷却されて、その屋内側の表面に結露を生じる可能性がある。そこで、本発明の框構造は、万一、屋外側框材４を構成する樹脂形材４２の表面に結露を生じても、その結露水が屋内側框材５を構成する木材を濡らすことなく良好に排水されるような対策を講じている。   The eaves structure for coupling the receiving piece 6 and the engagement piece 7 as described above includes an outdoor eave 4 made of only the aluminum mold 41 and an indoor eave 5 made of wood without the resin mold 42 interposed. However, in the exemplary embodiment, a resin mold 42 having the same thermal conductivity as that of the wood is sandwiched between the aluminum mold 41 and the wood so that the aluminum mold 42 and the wood are directly connected. It is configured not to contact. Further, the receiving piece 6 and the engaging piece 7 for joining the aluminum mold 42 and the wood are also formed of resin. In such a saddle structure, dew condensation usually occurs only on the surface of an aluminum mold having a high thermal conductivity. However, depending on the indoor / outdoor weather conditions, the sash usage, etc., the resin mold that is in contact with the aluminum mold 41 is used. 42 is also cooled slightly, and there is a possibility that condensation occurs on the indoor surface. Therefore, in the case of the cage structure of the present invention, even if dew condensation occurs on the surface of the resin profile 42 constituting the outdoor side cage material 4, the condensed water does not wet the wood constituting the indoor side cage material 5. Measures are taken to ensure good drainage.

すなわち、受けピース６を取り付けるために設けた屋外側框材４の凹部４４を、長さ方向に連続する一様断面に形成するとともに、受けピース６と係合ピース７との嵌合箇所においては、受けピース６の基板６１と係合ピース７の張出部７１との間、及び凹部４４の側壁と受けピース６の基板６１の側縁との間にそれぞれ若干の隙間Ｓ１、Ｓ２を確保して（図４参照）、上記凹部４４内の溝空間を長さ方向に連通させている。これにより、少なくとも戸先や召合せ部に配される縦框に関しては、凹部４４内に生じた結露水を凹部４４に沿って下方に流下させることができる。   That is, the concave portion 44 of the outdoor side frame 4 provided for attaching the receiving piece 6 is formed in a uniform cross section continuous in the length direction, and at the fitting position between the receiving piece 6 and the engaging piece 7 A slight gap S1, S2 is secured between the substrate 61 of the receiving piece 6 and the overhanging portion 71 of the engaging piece 7 and between the side wall of the recess 44 and the side edge of the receiving plate 6 of the receiving piece 6. (See FIG. 4), the groove space in the recess 44 is communicated in the length direction. Thereby, the dew condensation water generated in the concave portion 44 can flow downward along the concave portion 44 at least with respect to the vertical gutter arranged at the door tip or the summoning portion.

図１３は、戸先側の縦框（屋外側框材４ｈ及び屋内側框材５ｈ）を図１中のＸ−Ｘ’断面で切断した縦断面図である。縦框の上端部には樹脂製の上蓋部材９１が嵌装され、縦框の下端部には樹脂製の底蓋部材９２が嵌装されて、凹部４４の上下の開口をそれぞれ塞ぐとともに、吸水に弱い屋内側框材５ｈの木口面をカバーしている。そして、底蓋部材９２には、凹部４４の直下に連続するようにして排水孔９３が貫通形成されている。凹部４４内の結露水は、この排水孔９３を経由して下部の枠材３上に流下し、さらに枠材３に設けられた排水経路（図２中の破線）を通じて、屋外に排出される。図２中の符号９４は排水弁である。こうして、万一、凹部４４内に結露を生じても、その結露水は屋内側框材５を構成する木材の木口面を濡らすことなく、良好に排水される。   FIG. 13 is a longitudinal cross-sectional view of the doorside side vertical fence (outdoor side frame 4h and indoor side frame 5h) cut along the X-X ′ cross section in FIG. 1. A resin upper lid member 91 is fitted to the upper end of the vertical hook, and a resin bottom lid member 92 is fitted to the lower edge of the vertical hook to close the upper and lower openings of the recess 44 and absorb water. Covers the wood face of the indoor side wall material 5h, which is vulnerable to damage. A drain hole 93 is formed through the bottom lid member 92 so as to continue immediately below the recess 44. Condensed water in the recess 44 flows down onto the lower frame member 3 through the drain holes 93 and is discharged to the outside through a drainage path (broken line in FIG. 2) provided in the frame member 3. . Reference numeral 94 in FIG. 2 denotes a drain valve. In this way, even if dew condensation occurs in the recess 44, the dew condensation water is drained well without wetting the lumber surface of the wood constituting the indoor side wall material 5.

なお、横方向に配される上框及び下框については、凹部４４内での空気が上下方向には対流しないので、縦框に比べて結露が生じる可能性は極めて小さい。したがって、上記のような排水対策を講じなくとも実用面での支障はないと考えられる。   In addition, since the air in the recessed part 44 does not convect to the up-down direction about the upper side and the lower side which are arranged in the horizontal direction, the possibility of dew condensation is extremely small compared to the vertical side. Therefore, it is considered that there is no practical problem without taking the above drainage measures.
