図１は、第１実施形態の改装サッシ１の横方向断面図である。改装サッシ１は、新設障子１４と組み合わせて建具の一部として用いられる。室内空間と室外空間とを仕切る壁部２に開口部４を形成する躯体２８が設けられ、その躯体２８に改装サッシ１を含む建具が設けられる。躯体２８は、複数の骨組み材を組んだ骨組み構造体であって、ネジを螺合可能な木材や樹脂材などの材料で形成され、額縁部材２４等を支持する。室内空間と室外空間は、改装サッシ１に納められる新設障子１４の見込み方向両側に位置する。 FIG. 1 is a cross-sectional view of the modified sash 1 of the first embodiment. The refurbished sash 1 is used as a part of fittings in combination with the newly installed shoji screen 14. A skeleton 28 forming an opening 4 is provided in a wall portion 2 that separates an indoor space from an outdoor space, and the skeleton 28 is provided with fittings including a refurbished sash 1. The skeleton 28 is a skeleton structure in which a plurality of skeleton materials are assembled, and is made of a material such as wood or a resin material to which screws can be screwed, and supports a frame member 24 or the like. The indoor space and the outdoor space are located on both sides in the prospective direction of the new shoji screen 14 housed in the refurbished sash 1.

改装サッシ１は、新設枠１０、新設障子１４、ベース材１６、スペーサ１８、介在部材２０、見切材３２、気密テープ３４、カバー材３６、第１ネジ４０、第４ネジ４６、第５ネジ４８および第６ネジ４９を有する。 The refurbished sash 1 includes a new frame 10, a new shoji 14, a base material 16, a spacer 18, an intervening member 20, a parting material 32, an airtight tape 34, a cover material 36, a first screw 40, a fourth screw 46, and a fifth screw 48. And has a sixth screw 49.

新設枠１０は、改装のために新たに取り付けられ、新設障子１４を支持する枠体として機能する。新設枠１０は、金属材料や樹脂材料で押出成形等により形成され、新設上枠、新設下枠および一対の新設縦枠を有し、新設上枠、新設下枠および一対の新設縦枠を連結して矩形状に形成される。図１では、一方の縦枠を示し、一方の縦枠と同形状である他方の縦枠を省略する。 The new frame 10 is newly attached for refurbishment and functions as a frame body for supporting the new shoji screen 14. The new frame 10 is formed of a metal material or a resin material by extrusion molding or the like, has a new upper frame, a new lower frame, and a pair of new vertical frames, and connects the new upper frame, the new lower frame, and the pair of new vertical frames. Is formed into a rectangular shape. In FIG. 1, one vertical frame is shown, and the other vertical frame having the same shape as one vertical frame is omitted.

新設障子１４は、新設枠１０の内周側に設けられ、新設枠１０に取り付けられる。図１の例では、新設障子１４が２枚の態様を示すが、２枚に限られず、１枚、または３枚以上であってよい。なお以下の説明では、新設障子１４の厚み方向を見込み方向といい、見込み方向に直交する方向を見付け方向という。 The new shoji 14 is provided on the inner peripheral side of the new frame 10 and is attached to the new frame 10. In the example of FIG. 1, the newly installed shoji 14 shows an embodiment of two sheets, but the number is not limited to two, and may be one or three or more. In the following description, the thickness direction of the newly installed shoji 14 is referred to as the prospective direction, and the direction orthogonal to the prospective direction is referred to as the finding direction.

既設枠１２は、矩形状の枠体であって、改装前から第２ネジ４２および第３ネジ４４等により躯体２８に取り付けられている。既設枠１２および額縁部材２４は連結されている。既設枠１２は、既設上枠、既設下枠および一対の既設縦枠を有し、これらを連結して矩形状に形成される。既設枠１２は、金属材料で押出成形等により形成される。額縁部材２４は板材により矩形に形成される。 The existing frame 12 is a rectangular frame body, and is attached to the skeleton 28 by the second screw 42, the third screw 44, and the like before the remodeling. The existing frame 12 and the frame member 24 are connected to each other. The existing frame 12 has an existing upper frame, an existing lower frame, and a pair of existing vertical frames, and these are connected to form a rectangular shape. The existing frame 12 is made of a metal material and is formed by extrusion molding or the like. The frame member 24 is formed in a rectangular shape by a plate material.

見切材３２、気密テープ３４、カバー材３６は、室内側に設けられ、新設枠１０および既設枠１２の間を室内側から覆う。見切材３２は、第４ネジ４６により額縁部材２４に固定される。気密テープ３４は、新設枠１０および既設枠１２の室内側の隙間を覆うように設けられ、新設枠１０の室内側の端部および額縁部材２４に亘って取り付けられる。これにより水密性および気密性を高められる。カバー材３６は、新設枠１０および見切材３２の間に設けられ、新設枠１０側に取り付けられる。見切材３２およびカバー材３６により、新設枠１０および既設枠１２の室内側の隙間を覆って、改装サッシ１の室内側の意匠面を構成する。なお、見切材３２およびカバー材３６は２部材で構成される態様に限られず、飾り部材として１部材で構成されてよい。 The parting material 32, the airtight tape 34, and the cover material 36 are provided on the indoor side and cover the space between the new frame 10 and the existing frame 12 from the indoor side. The parting material 32 is fixed to the frame member 24 by the fourth screw 46. The airtight tape 34 is provided so as to cover the gap between the new frame 10 and the existing frame 12 on the indoor side, and is attached over the indoor end of the new frame 10 and the frame member 24. This enhances watertightness and airtightness. The cover material 36 is provided between the new frame 10 and the parting material 32, and is attached to the new frame 10 side. The parting material 32 and the cover material 36 cover the gaps on the indoor side of the new frame 10 and the existing frame 12, and form the indoor design surface of the refurbished sash 1. The parting material 32 and the cover material 36 are not limited to the embodiment composed of two members, and may be composed of one member as a decorative member.

ベース材１６は、既設枠１２の内周側に取り付けられ、新設枠１０を取り付けるために用いられる。ベース材１６と新設枠１０の間には介在部材２０が設けられる。ベース材１６は、第１ネジ４０により、既設枠１２および躯体２８に固定される。第１ネジ４０は、スペーサ１８に挿通する。スペーサ１８は、ベース材１６および既設枠１２の間に配置される。 The base material 16 is attached to the inner peripheral side of the existing frame 12 and is used for attaching the new frame 10. An intervening member 20 is provided between the base material 16 and the new frame 10. The base material 16 is fixed to the existing frame 12 and the skeleton 28 by the first screw 40. The first screw 40 is inserted through the spacer 18. The spacer 18 is arranged between the base material 16 and the existing frame 12.

新設枠１０は、ベース材１６の内周側で第５ネジ４８および第６ネジ４９によりベース材１６に固定される。第５ネジ４８は、室外側に位置し、ベース材１６および新設枠１０を連結する。第６ネジ４９は、室内側に位置し、ベース材１６および新設枠１０を連結する。なお、第６ネジ４９は、点線で示す第２ネジ４２に対して見付け方向にずれて位置する。新設枠１０の取り付けにベース材１６を用いることで、既設枠１２の形状に合わせた形状に新設枠１０を作り替える場合が少なくなり、新設枠１０を取り付け可能な既設枠１２の種類が増す。また、ベース材１６が第１ネジ４０により既設枠１２および躯体２８に固定されることで、ベース材１６と既設枠１２との間に介在部材を設けて、既設枠１２と介在部材に固定するネジと、ベース材１６と介在部材に固定するネジとを用いる場合と比べて、ネジ止め工程を減らすことができる。 The new frame 10 is fixed to the base material 16 by the fifth screw 48 and the sixth screw 49 on the inner peripheral side of the base material 16. The fifth screw 48 is located on the outdoor side and connects the base material 16 and the new frame 10. The sixth screw 49 is located on the indoor side and connects the base material 16 and the new frame 10. The sixth screw 49 is positioned so as to be offset in the finding direction with respect to the second screw 42 shown by the dotted line. By using the base material 16 for attaching the new frame 10, it is less likely that the new frame 10 will be remade into a shape that matches the shape of the existing frame 12, and the types of the existing frame 12 to which the new frame 10 can be attached will increase. Further, by fixing the base material 16 to the existing frame 12 and the skeleton 28 by the first screw 40, an intervening member is provided between the base material 16 and the existing frame 12 and fixed to the existing frame 12 and the intervening member. The number of screwing steps can be reduced as compared with the case where a screw and a screw fixed to the base material 16 and the intervening member are used.

図２（Ａ）は、ベース材１６、スペーサ１８および第１ネジ４０の側面図であり、図２（Ｂ）は、ベース材１６、スペーサ１８および第１ネジ４０の平面図である。ベース材１６は、新設枠１０の長手方向に沿って長手状に形成され、新設枠１０の全長に合わせた長さに形成される。 FIG. 2A is a side view of the base material 16, the spacer 18, and the first screw 40, and FIG. 2B is a plan view of the base material 16, the spacer 18, and the first screw 40. The base material 16 is formed in a longitudinal shape along the longitudinal direction of the new frame 10, and is formed to have a length that matches the total length of the new frame 10.

ベース材１６は、台座部６２、凹部６４、長孔部６６、外壁部６８および延出片７０を有する。台座部６２は、平板状であり、見込み方向に離れて一対形成される。台座部６２は、介在部材２０を介して新設枠１０を受ける座面として機能する。一対の台座部６２の間に凹部６４が形成される。台座部６２は、新設枠１０を固定するための固定部として機能する。 The base material 16 has a pedestal portion 62, a recess 64, an elongated hole portion 66, an outer wall portion 68, and an extension piece 70. The pedestal portions 62 have a flat plate shape and are formed in pairs separated from each other in the viewing direction. The pedestal portion 62 functions as a seat surface that receives the new frame 10 via the intervening member 20. A recess 64 is formed between the pair of pedestals 62. The pedestal portion 62 functions as a fixing portion for fixing the new frame 10.

複数の長孔部６６が凹部６４に見付け方向に離れて形成される。長孔部６６は、見込み方向に沿って長手状に形成される。長孔部６６は、長手状であるため第１ネジ４０を長孔部６６内でスライド可能であり、見込み方向のいずれかの位置に第１ネジ４０を挿入できる。これにより、異なる形状の既設枠１２に取り付け可能にできる。長孔部６６が台座部６２より凹んだ凹部６４に形成されることで、第１ネジ４０のネジ頭が台座部６２よりはみ出て介在部材２０に干渉しないようにできる。 A plurality of elongated holes 66 are formed in the recesses 64 apart from each other in the finding direction. The elongated hole portion 66 is formed in a longitudinal shape along the prospective direction. Since the elongated hole portion 66 has a longitudinal shape, the first screw 40 can be slid in the elongated hole portion 66, and the first screw 40 can be inserted at any position in the prospective direction. As a result, it can be attached to the existing frame 12 having a different shape. By forming the elongated hole portion 66 in the recess 64 recessed from the pedestal portion 62, the screw head of the first screw 40 can be prevented from protruding from the pedestal portion 62 and interfering with the intervening member 20.

外壁部６８は、ベース材１６の室外側端部から屈曲して見付け方向に延出する。延出片７０は、室外側に位置するが外壁部６８よりも室内側に形成され、既設枠１２に向かって延出する。延出片７０は、外壁部６８より長く延出する。延出片７０は、延出方向（横方向）の長さを短縮可能に設けられ、延出片７０を所定の長さで破断可能な切れ目を有する。切れ目は、ベース材１６の長手方向に沿って形成され、所定間隔毎に複数形成されてよい。作業者は、延出片７０の先端部を折り返すようにすれば、切れ目に沿って延出片７０の先端部が破断して、延出片７０の長さを短くすることができる。これにより、ベース材１６から既設枠１２までの距離に応じて、延出片７０の長さを変えることができ、延出片７０の先端を既設枠１２のベース板部５０に近接または当接した状態で取り付けることができる。 The outer wall portion 68 bends from the outdoor end portion of the base material 16 and extends in the finding direction. Although the extension piece 70 is located on the outdoor side, it is formed on the indoor side of the outer wall portion 68 and extends toward the existing frame 12. The extension piece 70 extends longer than the outer wall portion 68. The extension piece 70 is provided so that the length in the extension direction (lateral direction) can be shortened, and has a cut in which the extension piece 70 can be broken at a predetermined length. A plurality of cuts may be formed along the longitudinal direction of the base material 16 and may be formed at predetermined intervals. By folding back the tip of the extension piece 70, the operator can break the tip of the extension piece 70 along the cut and shorten the length of the extension piece 70. As a result, the length of the extension piece 70 can be changed according to the distance from the base material 16 to the existing frame 12, and the tip of the extension piece 70 is close to or abuts on the base plate portion 50 of the existing frame 12. It can be installed in the same state.

なお、長孔部６６は、３個である例を示しているが、これに限られなくてよく、既設枠１２に合わせたベース材１６の長さにもとづいて長孔部６６の個数が設定される。 Although the number of the elongated hole portions 66 is shown in the example of three, the number of the elongated hole portions 66 is not limited to this, and the number of the elongated hole portions 66 is set based on the length of the base material 16 according to the existing frame 12. Will be done.

スペーサ１８は、角柱状に形成され、第１ネジ４０を挿通される。スペーサ１８がベース材１６および既設枠１２に当接することで、新設枠１０および新設障子１４の荷重を受けたベース材１６の取付状態を安定させることができる。 The spacer 18 is formed in a prismatic shape, and the first screw 40 is inserted through the spacer 18. When the spacer 18 comes into contact with the base material 16 and the existing frame 12, the mounting state of the base material 16 under the load of the new frame 10 and the new shoji 14 can be stabilized.

図３は、既設枠１２に取り付けたベース材１６の斜視図である。図３では、既設枠１２の既設縦枠１２ａおよび既設下枠１２ｂと、ベース材１６の縦枠用の第１ベース材１６ａおよび下枠用の第２ベース材１６ｂが示される。 FIG. 3 is a perspective view of the base material 16 attached to the existing frame 12. FIG. 3 shows the existing vertical frame 12a and the existing lower frame 12b of the existing frame 12, the first base material 16a for the vertical frame of the base material 16, and the second base material 16b for the lower frame.

ベース材１６は、既設枠１２の一辺に対して１つずつ設けられ、ベース材１６を固定する既設枠１２の一辺の長さＬ２に応じた長さＬ１に設定される。このベース材１６の長さＬ１は、既設枠１２の一辺に沿う方向の長さであり、ベース材１６の長手方向の長さである。 The base material 16 is provided one by one for each side of the existing frame 12, and is set to a length L1 corresponding to the length L2 of one side of the existing frame 12 for fixing the base material 16. The length L1 of the base material 16 is the length in the direction along one side of the existing frame 12, and is the length in the longitudinal direction of the base material 16.

例えば、ベース材１６は、既設枠１２の一辺の全長（Ｌ２）をカバーするようにその一辺に亘った長さＬ１に設定され、既設枠１２の一辺の全長（Ｌ２）とほぼ同じ長さＬ１に設定されてよい。これにより、既設枠の一辺に対して複数のベース材を設ける場合より、部品点数を減らすことができ、取付作業を容易にできる。また、ベース材１６の長さＬ１は、既設枠１２の全長（Ｌ２）の２／３以上の長さに設定されてよい。 For example, the base material 16 is set to a length L1 over one side so as to cover the total length (L2) of one side of the existing frame 12, and is substantially the same length L1 as the total length (L2) of one side of the existing frame 12. May be set to. As a result, the number of parts can be reduced and the mounting work can be facilitated as compared with the case where a plurality of base materials are provided on one side of the existing frame. Further, the length L1 of the base material 16 may be set to a length of 2/3 or more of the total length (L2) of the existing frame 12.

図４（Ａ）は、上方から見たスペーサ１８の斜視図であり、図４（Ｂ）は、下方から見たスペーサ１８の斜視図である。スペーサ１８は、本体部７２、挿通孔７４、首部７６、頭部７８および被係合部８０を有する。 FIG. 4A is a perspective view of the spacer 18 seen from above, and FIG. 4B is a perspective view of the spacer 18 seen from below. The spacer 18 has a main body portion 72, an insertion hole 74, a neck portion 76, a head portion 78, and an engaged portion 80.

本体部７２は、断面長方形の柱状に形成される。本体部７２の断面の長辺に沿う方向を本体部７２の幅方向という。本体部７２を幅方向に長く形成することで、断面正方形である場合と比べて、既設枠１２への当接面積を確保できる。また、既設枠１２の形状に合わせて本体部７２の回転位置を変えることで、異なる形状の既設枠１２に取り付けやすくなる。 The main body 72 is formed in a columnar shape having a rectangular cross section. The direction along the long side of the cross section of the main body 72 is called the width direction of the main body 72. By forming the main body portion 72 longer in the width direction, it is possible to secure a contact area with the existing frame 12 as compared with the case where the cross section is square. Further, by changing the rotation position of the main body portion 72 according to the shape of the existing frame 12, it becomes easy to attach to the existing frame 12 having a different shape.

首部７６は、本体部７２の一端面から円筒状に突出する。頭部７８は、首部７６の端部から径方向外向きに張り出し、フランジ状に形成される。首部７６は、本体部７２および頭部７８を連結する。挿通孔７４は、本体部７２、首部７６および頭部７８の中央に貫通して形成され、第１ネジ４０を挿通可能である。被係合部８０は、本体部７２の他端面に凹んで形成される。被係合部８０は後述する第２スペーサに係合する。 The neck portion 76 projects cylindrically from one end surface of the main body portion 72. The head 78 projects radially outward from the end of the neck 76 and is formed in a flange shape. The neck portion 76 connects the main body portion 72 and the head portion 78. The insertion hole 74 is formed so as to penetrate through the center of the main body portion 72, the neck portion 76, and the head portion 78, and the first screw 40 can be inserted therethrough. The engaged portion 80 is formed by being recessed in the other end surface of the main body portion 72. The engaged portion 80 engages with a second spacer described later.

首部７６および頭部７８は、ベース材１６の長孔部６６に挿入可能である。図２（Ａ）に示すスペーサ１８がベース材１６に取り付けられた状態で、首部７６が長孔部６６に挿入され、本体部７２の一端面がベース材１６に当接する。スペーサ１８の取付姿勢は、図２（Ｂ）に示すように、ベース材１６の長手方向に対してスペーサ１８の幅方向が平行になってよく、直交してもよい。スペーサ１８の取付姿勢は、既設枠１２の形状に応じて定められる。 The neck portion 76 and the head portion 78 can be inserted into the elongated hole portion 66 of the base material 16. With the spacer 18 shown in FIG. 2A attached to the base material 16, the neck portion 76 is inserted into the elongated hole portion 66, and one end surface of the main body portion 72 abuts on the base material 16. As shown in FIG. 2B, the mounting posture of the spacer 18 may be parallel to the longitudinal direction of the base material 16 in the width direction of the spacer 18, or may be orthogonal to each other. The mounting posture of the spacer 18 is determined according to the shape of the existing frame 12.

図５は、第１実施形態の改装サッシ１の横方向断面図であり、図１に示す改装サッシ１を拡大した図である。既設枠１２は、ベース板部５０、第１突条部５２ａ、第２突条部５２ｂ、着座部５３および外壁部５４を有する。 FIG. 5 is a cross-sectional view of the refurbished sash 1 of the first embodiment, which is an enlarged view of the refurbished sash 1 shown in FIG. The existing frame 12 has a base plate portion 50, a first ridge portion 52a, a second ridge portion 52b, a seating portion 53, and an outer wall portion 54.

ベース板部５０は、開口部４の縦辺に沿って延在するとともに、横方向断面において室外側から額縁部材２４に向かって見込み方向に延在する。第１突条部５２ａおよび第２突条部５２ｂは、ベース板部５０から内周向きに突出して形成される。 The base plate portion 50 extends along the vertical side of the opening 4 and extends in the prospective direction from the outdoor side toward the frame member 24 in the cross section in the horizontal direction. The first ridge portion 52a and the second ridge portion 52b are formed so as to project inward from the base plate portion 50.

外壁部５４は、ベース板部５０の室外側の端部から外周向きに突出する。着座部５３は、ベース板部５０の室内側の端部に形成され、額縁部材２４の表面に引っかかるように着座する。着座部５３は、第２ネジ４２により躯体２８にネジ止めされる。ベース板部５０は、第３ネジ４４により躯体２８にネジ止めされる。 The outer wall portion 54 projects outward from the outdoor end of the base plate portion 50. The seating portion 53 is formed at the end portion of the base plate portion 50 on the indoor side, and is seated so as to be caught on the surface of the frame member 24. The seating portion 53 is screwed to the skeleton 28 by the second screw 42. The base plate portion 50 is screwed to the skeleton 28 by the third screw 44.

新設枠１０は、ベース板部５６、第１突条部５８ａ、第２突条部５８ｂ、第３突条部５８ｃ、第４突条部５８ｄおよび外壁部６０を有する。ベース板部５６は、開口部４の縦辺に沿って延在し、横方向断面において見込み方向に延在する。ベース板部５６は、第５ネジ４８等によりベース材１６の台座部６２に固定される。一対の台座部６２がそれぞれベース板部５６にネジ止めされてよい。第５ネジ４８および第６ネジ４９は、台座部６２にそれぞれネジ止めされる。第１突条部５８ａ、第２突条部５８ｂ、第３突条部５８ｃおよび第４突条部５８ｄは、ベース板部５６から内周側に突出する。外壁部６０は、ベース板部５６の室外側の端部から外周向きに突出する。 The new frame 10 has a base plate portion 56, a first ridge portion 58a, a second ridge portion 58b, a third ridge portion 58c, a fourth ridge portion 58d, and an outer wall portion 60. The base plate portion 56 extends along the vertical side of the opening 4 and extends in the prospective direction in the cross section in the transverse direction. The base plate portion 56 is fixed to the pedestal portion 62 of the base material 16 by a fifth screw 48 or the like. The pair of pedestals 62 may be screwed to the base plate 56, respectively. The fifth screw 48 and the sixth screw 49 are screwed to the pedestal portion 62, respectively. The first ridge portion 58a, the second ridge portion 58b, the third ridge portion 58c, and the fourth ridge portion 58d project from the base plate portion 56 toward the inner peripheral side. The outer wall portion 60 projects outward from the outdoor end of the base plate portion 56.

第１ネジ４０は、既設枠１２の形状に応じて長孔部６６のいずれかの位置に挿入されて既設枠１２を貫通して既設枠１２に止め付けられる。これにより、既設枠１２に孔部５５が形成される。つまり、長孔部６６の長手状の範囲のうち、既設枠１２に貫通させる位置に第１ネジ４０が挿入されて、既設枠１２に止め付けられる。これにより、ベース材１６が既設枠１２に固定される。第１ネジ４０は、長孔部６６に挿入された状態でスライド可能であるため、既設枠１２に止め付ける位置に応じて長孔部６６への挿入位置を変更できる。長孔部６６によりベース材１６を取り付け可能な既設枠１２の種類が増し、異なる幅の既設枠１２に対して第１ネジ４０を長孔部６６のいずれかの位置でねじ込むことが可能となる。 The first screw 40 is inserted into any position of the elongated hole portion 66 according to the shape of the existing frame 12, penetrates the existing frame 12, and is fastened to the existing frame 12. As a result, the hole 55 is formed in the existing frame 12. That is, the first screw 40 is inserted into the position of penetrating the existing frame 12 in the longitudinal range of the elongated hole portion 66, and is fixed to the existing frame 12. As a result, the base material 16 is fixed to the existing frame 12. Since the first screw 40 is slidable while being inserted into the elongated hole portion 66, the insertion position into the elongated hole portion 66 can be changed according to the position to be fastened to the existing frame 12. The types of the existing frame 12 to which the base material 16 can be attached are increased by the elongated hole portion 66, and the first screw 40 can be screwed into the existing frame 12 having a different width at any position of the elongated hole portion 66. ..

ベース材１６の長孔部６６は、額縁部材２４よりも内周側に位置する。長孔部６６は、額縁部材２４よりも室外側に位置しており、既設枠１２とベース材１６との距離が大きく空いている。第１ネジ４０は、躯体２８まで達する長さである。 The elongated hole portion 66 of the base material 16 is located on the inner peripheral side of the frame member 24. The elongated hole portion 66 is located on the outdoor side of the frame member 24, and the distance between the existing frame 12 and the base material 16 is large. The first screw 40 has a length that reaches the skeleton 28.

長孔部６６の周りは丸孔と比べてベース材１６の剛性が低下するおそれがあるが、既設枠１２およびベース材１６の間にスペーサ１８が設けられるため、新設枠１０からの荷重をベース材１６からスペーサ１８を介して既設枠１２に十分に伝達できる。 The rigidity of the base material 16 may be lower around the elongated hole portion 66 than that of the round hole, but since the spacer 18 is provided between the existing frame 12 and the base material 16, the load from the new frame 10 is used as the base. It can be sufficiently transmitted from the material 16 to the existing frame 12 via the spacer 18.

ベース材１６の台座部６２が見込み方向に沿って平行に設けられるよう、延出片７０は、延出片７０の先端がベース材１６および既設枠１２との距離に応じて破断される。これにより、ベース材１６が新設枠１０から荷重を受けた場合に、延出片７０が既設枠１２に当接して、ベース材１６の室外側部分の変形を抑えることができる。 In the extension piece 70, the tip of the extension piece 70 is broken according to the distance between the base material 16 and the existing frame 12 so that the pedestal portion 62 of the base material 16 is provided in parallel along the prospective direction. As a result, when the base material 16 receives a load from the new frame 10, the extension piece 70 comes into contact with the existing frame 12, and deformation of the outdoor portion of the base material 16 can be suppressed.

図６は、第２実施形態の改装サッシ１００について説明するための図であり、改装サッシ１００の横方向断面図を示す。第２実施形態の改装サッシ１００は、図５に示す第１実施形態の改装サッシ１と比べて、ベース材１６および既設枠１１２の距離が異なり、スペーサ１１８の軸方向長さが異なる。スペーサ１１８の軸方向長さとは、第１ネジ４０の軸方向に平行な長さである。 FIG. 6 is a diagram for explaining the refurbished sash 100 of the second embodiment, and shows a lateral sectional view of the refurbished sash 100. The refurbished sash 100 of the second embodiment has a different distance between the base material 16 and the existing frame 112 and a different axial length of the spacer 118 as compared with the refurbished sash 1 of the first embodiment shown in FIG. The axial length of the spacer 118 is a length parallel to the axial direction of the first screw 40.

既設枠１１２は、ベース板部５６の外周側にホロー形成部５７が設けられており、ホローを有している。第１ネジ４０は、既設枠１１２に止め付けられる。このように、ベース材１６が図５に示すように躯体２８および既設枠１２に固定されるだけでなく、既設枠１１２のみに固定されることがある。いずれにしても、ベース材１６は、既設枠１１２の内周側で既設枠１１２に固定される。 The existing frame 112 is provided with a hollow forming portion 57 on the outer peripheral side of the base plate portion 56, and has a hollow. The first screw 40 is fastened to the existing frame 112. In this way, the base material 16 is not only fixed to the skeleton 28 and the existing frame 12 as shown in FIG. 5, but may be fixed only to the existing frame 112. In any case, the base material 16 is fixed to the existing frame 112 on the inner peripheral side of the existing frame 112.

新設枠１１０は、見込み方向に延在する本体部１１０ａと、本体部１１０ａの室外側の端部に結合する外壁部１１０ｂとにより構成される。スペーサ１１８は、第１スペーサ１８ａおよび第２スペーサ１８ｂにより構成されている。このスペーサ１１８について新たな図面を参照して説明する。 The new frame 110 is composed of a main body portion 110a extending in the prospective direction and an outer wall portion 110b connected to the outdoor end of the main body portion 110a. The spacer 118 is composed of a first spacer 18a and a second spacer 18b. The spacer 118 will be described with reference to the new drawings.

図７（Ａ）は、スペーサ１１８の斜視図であり、図７（Ｂ）は、スペーサ１１８の分解図である。スペーサ１１８は、挿通孔７４の軸方向に連結可能であり、第１スペーサ１８ａに第２スペーサ１８ｂを連結させて長さ調整可能である。第１スペーサ１８ａに複数の第２スペーサ１８ｂが連結されてもよい。 7 (A) is a perspective view of the spacer 118, and FIG. 7 (B) is an exploded view of the spacer 118. The spacer 118 can be connected in the axial direction of the insertion hole 74, and the length can be adjusted by connecting the second spacer 18b to the first spacer 18a. A plurality of second spacers 18b may be connected to the first spacer 18a.

第１スペーサ１８ａは、図４（Ａ）および図４（Ｂ）に示すスペーサ１８と同じ形状であり、同じ構成を有する。図７（Ｂ）に示すように、第２スペーサ１８ｂは、係合部８２および挿通孔８４を有する。挿通孔８４は、第１ネジ４０を挿通可能であり、第１スペーサ１８ａの挿通孔７４と同軸に設けられる。 The first spacer 18a has the same shape as the spacer 18 shown in FIGS. 4A and 4B, and has the same configuration. As shown in FIG. 7B, the second spacer 18b has an engaging portion 82 and an insertion hole 84. The insertion hole 84 is capable of inserting the first screw 40 and is provided coaxially with the insertion hole 74 of the first spacer 18a.

係合部８２は、第２スペーサ１８ｂの端面に突出して、一対形成される。係合部８２は、図４（Ｂ）に示す被係合部８０に挿入されて係合する。係合部８２は、外周面にリブ８２ａを有する。リブ８２ａは、外周面から径方向外向きに突出し、被係合部８０へ挿入すると被係合部８０の内周面に圧接する。これにより、第２スペーサ１８ｂが第１スペーサ１８ａに連結される。なお、被係合部８０および係合部８２の凹凸関係は逆であってよく、被係合部８０が凸状に形成され、係合部８２が凹状に形成されてよい。 The engaging portions 82 project to the end faces of the second spacer 18b and form a pair. The engaging portion 82 is inserted into and engaged with the engaged portion 80 shown in FIG. 4 (B). The engaging portion 82 has a rib 82a on the outer peripheral surface. The rib 82a protrudes radially outward from the outer peripheral surface, and when inserted into the engaged portion 80, the rib 82a is in pressure contact with the inner peripheral surface of the engaged portion 80. As a result, the second spacer 18b is connected to the first spacer 18a. The concave-convex relationship between the engaged portion 80 and the engaged portion 82 may be reversed, and the engaged portion 80 may be formed in a convex shape and the engaged portion 82 may be formed in a concave shape.

図６に戻る。作業者は、ベース材１６と既設枠１１２の距離に合わせて第１スペーサ１８ａに第２スペーサ１８ｂを連結する。これにより、スペーサ１１８の軸方向長さを調整できる。なお、第１スペーサ１８ａに第２スペーサ１８ｂは複数連結され、第２スペーサ１８ｂに別の第２スペーサ１８ｂが連結されてもよい。既設枠１２のベース板部５０と着座部５３との高さが異なる種類の既設枠１２においても、スペーサ１１８の軸方向長さを調整してベース材１６を取り付け可能となる。このように、スペーサ１１８の軸方向長さの調整によって、ベース材１６を取り付け可能な既設枠１２の種類を増すことができる。 Return to FIG. The operator connects the second spacer 18b to the first spacer 18a according to the distance between the base material 16 and the existing frame 112. Thereby, the axial length of the spacer 118 can be adjusted. A plurality of second spacers 18b may be connected to the first spacer 18a, and another second spacer 18b may be connected to the second spacer 18b. Even in the existing frame 12 of a type in which the heights of the base plate portion 50 and the seating portion 53 of the existing frame 12 are different, the base material 16 can be attached by adjusting the axial length of the spacer 118. In this way, by adjusting the axial length of the spacer 118, it is possible to increase the types of the existing frame 12 to which the base material 16 can be attached.

延出片７０の延出方向の長さは、第１スペーサ１８ａおよび第２スペーサ１８ｂを連結した場合に合わせて設定される。第１スペーサ１８ａおよび第２スペーサ１８ｂを連結した場合には、延出片７０の先端部の破断は不要であるが、第１スペーサ１８ａのみを取り付ける場合には、延出片７０の先端部を切れ目７０ａに沿って破断して取り付けられる。 The length of the extension piece 70 in the extension direction is set according to the case where the first spacer 18a and the second spacer 18b are connected. When the first spacer 18a and the second spacer 18b are connected, it is not necessary to break the tip of the extension piece 70, but when only the first spacer 18a is attached, the tip of the extension piece 70 is broken. It is attached by breaking along the cut 70a.

延出片７０は、第１スペーサ１８ａの長さに合わせた位置で破断可能に設けられ、第２スペーサ１８ｂの長さ分を折って切り捨てることができる。延出片７０とスペーサ１１８とにより既設枠１１２とベース材１６との距離を調整することで、台座部６２を見込み方向に平行に取り付けて、ベース材１６の取付状態を安定させることができる。また、ベース材１６と既設枠１２を室外側部分で固定する必要がなくなるため、取付作業を容易にすることができる。切れ目７０ａは延出片７０に複数設けられてよい。 The extension piece 70 is provided so as to be breakable at a position corresponding to the length of the first spacer 18a, and the length of the second spacer 18b can be folded and cut off. By adjusting the distance between the existing frame 112 and the base material 16 by the extension piece 70 and the spacer 118, the pedestal portion 62 can be attached in parallel in the prospective direction, and the attached state of the base material 16 can be stabilized. Further, since it is not necessary to fix the base material 16 and the existing frame 12 at the outdoor side portion, the mounting work can be facilitated. A plurality of cuts 70a may be provided in the extension piece 70.
