It is in.

以下、図6〜図10を適宜参照しながら建物の取付枠4の開口部4aに枠体10を取り付ける手順について説明を行う。なお、上枠11、下枠12及び左右の縦枠13をそれぞれまぐさ2、窓台3及び柱1に取り付ける手順は互いにほぼ共通である。従って、以下においては代表例として、一方の縦枠13を柱1に取り付ける手順について説明することとする。 Hereinafter, a procedure for attaching the frame body 10 to the opening 4a of the attachment frame 4 of the building will be described with reference to FIGS. 6 to 10 as appropriate. The procedure for attaching the upper frame 11, the lower frame 12, and the left and right vertical frames 13 to the lintel 2, the window sill 3, and the pillar 1 is almost the same. Therefore, in the following, as a typical example, a procedure for attaching one of the vertical frames 13 to the pillar 1 will be described.

まず、図6に示すように、見付け下張り材5の室外側面5aに固定用フィン部70を当接させ、この状態から固定用フィン部70を介して取付枠4にネジ74を螺合すれば、モール部13Bを柱1に取り付けることが可能となる。このとき、固定用フィン部70は、縦枠基板部60からの外周側への突出寸法が防水用フィン部71よりも大きく設定してあるため、ネジ74を螺合する作業を容易に行うことができる。この状態から固定用フィン部70及び見付け下張り材5の室外側面5aを覆うように断熱材8を配置する。断熱材8としては、固定用フィン部70と防水用フィン部71との相互間隔にほぼ等しい板厚を有したものを適用している。 First, as shown in FIG. 6, the fixing fin portion 70 is brought into contact with the outdoor surface 5a of the finding underlaying material 5, and from this state, the screw 74 is screwed into the mounting frame 4 via the fixing fin portion 70. , The molding portion 13B can be attached to the pillar 1. At this time, since the fixing fin portion 70 is set to have a larger protrusion dimension from the vertical frame substrate portion 60 to the outer peripheral side than the waterproof fin portion 71, the work of screwing the screw 74 can be easily performed. Can be done. From this state, the heat insulating material 8 is arranged so as to cover the outdoor side surface 5a of the fixing fin portion 70 and the finding underlaying material 5. As the heat insulating material 8, a material having a plate thickness substantially equal to the mutual distance between the fixing fin portion 70 and the waterproof fin portion 71 is applied.

断熱材8を配置した後においては、図7に示すように、防水用フィン部71の室外側面71aから断熱材8の室外側面8aの間にわたって防水テープ(防水部材)80を貼り付け、さらに防水テープ80を覆い隠すように、防水用フィン部71の室外側面71aから断熱材8の室外側面8a全域にわたって防水シート(防水部材)81を配設する。この状態においては、防水シート81によって断熱材8の室外側面8aが完全に覆われるとともに、防水テープ80によって断熱材8と防水用フィン部71との隙間が塞がれた状態となる。従って、断熱材8の室外側から水が付着したとしても、その水が断熱材8に浸入したり、断熱材8と防水用フィン部71との隙間から取付枠4側に浸入したりするおそれがなくなる。 After arranging the heat insulating material 8, as shown in FIG. 7, a waterproof tape (waterproof member) 80 is attached between the outdoor surface 71a of the waterproof fin portion 71 and the outdoor surface 8a of the heat insulating material 8, and further waterproofed. A waterproof sheet (waterproof member) 81 is arranged over the entire area from the outdoor surface 71a of the waterproof fin portion 71 to the outdoor surface 8a of the heat insulating material 8 so as to cover the tape 80. In this state, the outdoor surface 8a of the heat insulating material 8 is completely covered by the waterproof sheet 81, and the gap between the heat insulating material 8 and the waterproof fin portion 71 is closed by the waterproof tape 80. Therefore, even if water adheres from the outdoor side of the heat insulating material 8, the water may infiltrate into the heat insulating material 8 or enter the mounting frame 4 side through the gap between the heat insulating material 8 and the waterproof fin portion 71. Is gone.

次いで、図8及び図9に示すように、断熱材8の適宜箇所に胴縁82を設け、断熱材8の室外側面8aとの間に通気層Vを確保した状態で外壁材9を配置する。外壁材9の端面とモール部13Bの外周面との間にシーリング材83を充填すれば、取付枠4に対するモール部13Bの取り付けが完了する。図には明示していないが、上述したように、上枠11のモール部11B及び下枠12のモール部12Bについても同様の手順で取付枠4に取り付けられることになる。 Next, as shown in FIGS. 8 and 9, the furring strip 82 is provided at an appropriate position of the heat insulating material 8, and the outer wall material 9 is arranged in a state where the ventilation layer V is secured between the heat insulating material 8 and the outdoor surface 8a. .. If the sealing material 83 is filled between the end surface of the outer wall material 9 and the outer peripheral surface of the molding portion 13B, the attachment of the molding portion 13B to the mounting frame 4 is completed. Although not explicitly shown in the drawing, as described above, the molding portion 11B of the upper frame 11 and the molding portion 12B of the lower frame 12 are also attached to the mounting frame 4 in the same procedure.

この状態から、図10及び図11に示すように、モール部11B,12B,13Bに対して窓枠部11A,12A,13Aを一体化させれば、取付枠4の開口部4aに建具を取り付けることができる。より具体的には、図10に示すように、見込み下張り材7と窓枠部13Aとの間にスペーサ部材90を介在させた状態でモール部13Bと窓枠部13Aとをそれぞれ一体化し、この状態から、図2に示すように、固定ヒレ部32及びスペーサ部材90を介して柱1にネジ75を螺合させれば、左右の縦枠13をそれぞれ取付枠4の開口部4aに取り付けることができる。スペーサ部材90としては、室内側に位置する部分と、室外側に位置する部分とで異なる材質のものを適用することが好ましい。すなわち、固定ヒレ部32を介してネジ75を螺合する室内側の部分には、木質材等のように比較的剛性を有したスペーサ部材90aを適用し、室外側となる部分については、断熱性の高い材質から成るスペーサ部材90bを適用すれば、窓枠部13Aの取付枠4への取り付けを確実にすることができるとともに、スペーサ部材90が室外と室内との間の熱橋となる事態を防止して断熱性の向上を図ることができる。 From this state, as shown in FIGS. 10 and 11, if the window frame portions 11A, 12A, and 13A are integrated with the molding portions 11B, 12B, and 13B, the fitting is attached to the opening 4a of the mounting frame 4. be able to. More specifically, as shown in FIG. 10, the molding portion 13B and the window frame portion 13A are integrated with the spacer member 90 interposed between the prospective underlaying member 7 and the window frame portion 13A. From the state, as shown in FIG. 2, if the screw 75 is screwed into the pillar 1 via the fixed fin portion 32 and the spacer member 90, the left and right vertical frames 13 are attached to the openings 4a of the attachment frame 4, respectively. Can be done. As the spacer member 90, it is preferable to use different materials for the portion located on the indoor side and the portion located on the outdoor side. That is, a spacer member 90a having a relatively high rigidity such as a wooden material is applied to the portion on the indoor side where the screw 75 is screwed via the fixed fin portion 32, and the portion on the outdoor side is heat-insulated. By applying the spacer member 90b made of a highly rigid material, it is possible to ensure that the window frame portion 13A is attached to the mounting frame 4, and the spacer member 90 becomes a thermal bridge between the outdoor and the indoor. Can be prevented and the heat insulating property can be improved.

ネジ75を螺合した固定ヒレ部32については、その内周側の内周側額縁部材91を配設することによってネジ75の頭部が外部に露出する事態を防止することができる。スペーサ部材90については、内周側額縁部材91から内壁材6の室内に臨む表面までの間に見付け側額縁部材92を配設することによって室内側に露出する事態を防止することができる。 With respect to the fixed fin portion 32 into which the screw 75 is screwed, it is possible to prevent the head of the screw 75 from being exposed to the outside by disposing the inner peripheral side frame member 91 on the inner peripheral side thereof. The spacer member 90 can be prevented from being exposed to the indoor side by disposing the finding side frame member 92 between the inner peripheral side frame member 91 and the surface of the inner wall material 6 facing the room.

一方、上枠11及び下枠12については、図11に示すように、窓台3に直接下枠12の窓枠部12Aを配置する一方、まぐさ2と窓枠部11Aとの間にスペーサ部材90を介在させた状態でモール部11B,12Bと窓枠部11A,12Aとをそれぞれ一体化する。この状態から、図1に示すように、固定ヒレ部32を介して窓台3にネジ75を螺合するとともに、固定ヒレ部32及びスペーサ部材90を介してまぐさ2にネジ75を螺合すれば、上枠11及び下枠12をそれぞれ取付枠4の開口部4aに取り付けることができる。縦枠13と同様、固定ヒレ部32については、その内周側の見付け面に内周側額縁部材91を配設することによってネジ75の頭部が外部に露出する事態を防止することができる。上枠11のスペーサ部材90については、内周側額縁部材91から内壁材6の室内に臨む表面までの間に見付け側額縁部材92を配設することによって室内側に露出する事態を防止することができる。下枠12については窓枠部12Aを直接窓台3に当接させているが、上枠11と同様、内周側額縁部材91から内壁材6の室内に臨む表面までの間に見付け側額縁部材92を配設するようにしている。 On the other hand, regarding the upper frame 11 and the lower frame 12, as shown in FIG. 11, the window frame portion 12A of the lower frame 12 is directly arranged on the window base 3, while the spacer between the lintel 2 and the window frame portion 11A. The molding portions 11B and 12B and the window frame portions 11A and 12A are integrated with the member 90 interposed therebetween. From this state, as shown in FIG. 1, the screw 75 is screwed into the window sill 3 via the fixed fin portion 32, and the screw 75 is screwed into the forage 2 via the fixed fin portion 32 and the spacer member 90. Then, the upper frame 11 and the lower frame 12 can be attached to the opening 4a of the attachment frame 4, respectively. Similar to the vertical frame 13, by disposing the inner peripheral side frame member 91 on the finding surface on the inner peripheral side of the fixed fin portion 32, it is possible to prevent the head of the screw 75 from being exposed to the outside. .. The spacer member 90 of the upper frame 11 is prevented from being exposed to the indoor side by arranging the finding side frame member 92 between the inner peripheral side frame member 91 and the surface of the inner wall material 6 facing the room. Can be done. Regarding the lower frame 12, the window frame portion 12A is directly brought into contact with the window base 3, but like the upper frame 11, the found side frame is between the inner peripheral side frame member 91 and the surface of the inner wall material 6 facing the room. The member 92 is arranged.

さらに、この建具では、図1及び図2に示すように、縦枠取付部62にそれぞれブラケット101を介してルーバユニット(外付け部品)100が保持してある。ブラケット101は、取付ネジ102の頭部と、縦枠取付部62に配置した連結プレート103との間に挟持された状態で縦枠取付部62に取り付けてある。従って、縦枠取付部62の長手方向においてブラケット101の取り付け位置を変更することにより、ルーバユニット100の取り付け位置を調整することが可能となる。 Further, in this fitting, as shown in FIGS. 1 and 2, the louver unit (external component) 100 is held by the vertical frame mounting portion 62 via the bracket 101, respectively. The bracket 101 is attached to the vertical frame mounting portion 62 in a state of being sandwiched between the head of the mounting screw 102 and the connecting plate 103 arranged in the vertical frame mounting portion 62. Therefore, the mounting position of the louver unit 100 can be adjusted by changing the mounting position of the bracket 101 in the longitudinal direction of the vertical frame mounting portion 62.

上記のように構成した建具では、枠体10を構成する枠材11,12,13が、取付枠4との取り付けに必要となる固定用フィン部70に加えて、断熱材8の室外側面8aに当接する防水用フィン部71を有し、かつ防水用フィン部71の室外側面71aと断熱材8の室外側面8aとにわたって防水テープ80及び防水シート81を設けるようにしている。従って、外壁材9との間の通気層Vに雨水等の水が浸入した場合にも、断熱材8が水濡れすることがなく、その断熱性に支障を来すおそれもない。さらに、モール部11B,12B,13B及び窓枠部11A,12A,13Aによって枠材11,12,13を構成し、断熱材8の内周面8bや外壁材9の内周面9bの見切り材としてモール部11B,12B,13Bを配置するようにしているため、窓枠部11A,12A,13Aを室内側に配置して取付枠4との掛かり代を十分に確保することができる。しかも、取付枠4との取り付けについては、固定用フィン部70と取付枠4との間が直接ネジ74で螺合されるため、ふかし材等の調整部材を要しない。これらの結果、この建具によれば、取付枠4の開口部4aに対して高い寸法精度で枠体10を取り付けることが可能となる。 In the fittings constructed as described above, the frame members 11, 12, and 13 constituting the frame body 10 are the outdoor side surface 8a of the heat insulating material 8 in addition to the fixing fin portion 70 required for mounting with the mounting frame 4. The waterproof fin portion 71 is provided in contact with the waterproof fin portion 71, and the waterproof tape 80 and the waterproof sheet 81 are provided over the outdoor surface 71a of the waterproof fin portion 71 and the outdoor surface 8a of the heat insulating material 8. Therefore, even when water such as rainwater infiltrates the ventilation layer V between the outer wall material 9 and the heat insulating material 8, the heat insulating material 8 does not get wet and there is no possibility that the heat insulating property is hindered. Further, the frame members 11, 12, 13 are formed by the molding portions 11B, 12B, 13B and the window frame portions 11A, 12A, 13A, and the inner peripheral surface 8b of the heat insulating material 8 and the inner peripheral surface 9b of the outer wall material 9 are parting members. Since the molding portions 11B, 12B, and 13B are arranged as such, the window frame portions 11A, 12A, and 13A can be arranged on the indoor side to sufficiently secure the hooking allowance with the mounting frame 4. Moreover, for mounting with the mounting frame 4, since the fixing fin portion 70 and the mounting frame 4 are directly screwed with the screw 74, an adjusting member such as a puffing material is not required. As a result, according to this fitting, the frame body 10 can be attached to the opening 4a of the attachment frame 4 with high dimensional accuracy.

加えて、この建具では、図10及び図11に示すように、内周側額縁部材91及び見付け側額縁部材92を取り外した後、固定ヒレ部32に螺合していたネジ75を取り外し、さらにスペーサ部材90を除去すれば、窓枠部11A,13Aとモール部11B,13Bとを連結しているネジ73の頭部が室内側に露出した状態となる。従って、このネジ73を取り外せば、モール部11B,13Bとの連結状態が解除された窓枠部11A,13Aを、窓枠部12Aとともに室内側に引き出すことができ、例えば、新たな窓枠部と交換することができる。このとき、モール部11B,12B,13Bは、いずれも取付枠4に取り付けられた状態のままであるため、防水テープ80や防水シート81を剥がしたり、固定用フィン部70に螺合したネジ74を取り外すために外壁材9を除去する等の作業を行う必要がない。従って、建具を交換する際の作業を容易に、かつ短時間に行うことが可能となる。 In addition, in this fitting, as shown in FIGS. 10 and 11, after removing the inner peripheral side frame member 91 and the finding side frame member 92, the screw 75 screwed to the fixed fin portion 32 is removed, and further. When the spacer member 90 is removed, the head of the screw 73 connecting the window frame portions 11A and 13A and the molding portions 11B and 13B is exposed to the indoor side. Therefore, if the screw 73 is removed, the window frame portions 11A and 13A whose connection with the molding portions 11B and 13B is released can be pulled out together with the window frame portion 12A to the indoor side. For example, a new window frame portion can be pulled out. Can be exchanged for. At this time, since the molding portions 11B, 12B, and 13B are all still attached to the mounting frame 4, the waterproof tape 80 and the waterproof sheet 81 are peeled off, and the screws 74 screwed into the fixing fin portions 70. It is not necessary to perform work such as removing the outer wall material 9 in order to remove the outer wall material 9. Therefore, it is possible to easily and in a short time the work of exchanging the fittings.

なお、上述した実施の形態では、縦すべり出し窓を例示しているが、必ずしも縦すべり出し窓である必要はなく、その他の障子を備える建具にも適用することが可能である。また、縦枠13のモール部13Bに縦枠取付部62を設け、縦枠取付部62を介してルーバユニット100を保持させるようにしているため、外壁材9にネジを螺合する必要がなく、躯体側への水の浸入を防止する点で有利となる。しかしながら、本発明では必ずしもモール部13Bに取付部62を設ける必要はない。なお、取付部に保持させる外付け部品としては、必ずしもルーバユニットに限らず、例えば面格子や日よけ等々のその他のものであってももちろん良い。 In the above-described embodiment, the vertical sliding window is illustrated, but it does not necessarily have to be the vertical sliding window, and it can be applied to other fittings provided with shoji screens. Further, since the vertical frame mounting portion 62 is provided in the molding portion 13B of the vertical frame 13 and the louver unit 100 is held via the vertical frame mounting portion 62, there is no need to screw screws into the outer wall material 9. , It is advantageous in preventing water from entering the skeleton side. However, in the present invention, it is not always necessary to provide the mounting portion 62 on the molding portion 13B. The external component to be held by the mounting portion is not necessarily limited to the louver unit, and may of course be other components such as a surface grid and a shade.

また、上述した実施の形態では、躯体に対する枠体10の取り付け手順として、先にモール部を取り付けた後にモール部に窓枠部を連結して両者を一体化させるようにしているが、予めモール部と窓枠部とを一体化した状態で躯体に取り付けるようにしても構わない。なお、取付枠4の見付け面に下張り材5,7を設けるようにしているが、これらの下張り材は必ずしも設ける必要はない。 Further, in the above-described embodiment, as a procedure for attaching the frame body 10 to the skeleton, the molding portion is first attached and then the window frame portion is connected to the molding portion to integrate the two. The portion and the window frame portion may be attached to the skeleton in an integrated state. Although the underlaying materials 5 and 7 are provided on the finding surface of the mounting frame 4, these underlaying materials do not necessarily have to be provided.
