Description

本発明は、例えばカーテンウォールの内窓として使用される開口部装置に関する。 The present invention relates to an opening arrangement, for example for use as an inner window in a curtain wall.

例えば特許文献1には、建物の外壁を構成するカーテンウォールにおいて、防火構造を備えた構成が開示されている。この構成では、防火設備が必要な部分と必要でない部分とでカーテンウォールの構造を異ならせ、これにより延焼のおそれがある部分での防火対策を構築している。また、特許文献2には、建物の外壁を構成するカーテンウォールの室内側に内窓として開き窓を設置した構成が開示されている。 For example, Patent Literature 1 discloses a configuration in which a curtain wall constituting an outer wall of a building is provided with a fireproof structure. In this configuration, the structure of the curtain wall is made different between the part that requires fire prevention equipment and the part that does not, thereby constructing fire prevention measures in the part where there is a risk of fire spreading. Further, Patent Document 2 discloses a configuration in which a casement window is installed as an inner window on the indoor side of a curtain wall that constitutes the outer wall of a building.

実開平3-58589号公報Japanese Utility Model Laid-Open No. 3-58589

上記特許文献1のカーテンウォールは、防火部分と非防火部分とで建物の外観が異なるため、建物の外観意匠を低下させている。そこで、この対策として、カーテンウォール自体は全て同一の非防火設備で構成し、その室内側に防火対策を施した内窓(開口部装置)を設けることで、必要な部分での防火対策を構築することが考えられる。ところが、カーテンウォールの室内側に内窓を設置すると、カーテンウォールと内窓との間の空間に結露を生じ、或いはこの空間に塵や虫等が侵入する懸念がある。このため、内窓は、容易に移動させてメンテナンスや掃除を行えることが望ましい。なお、上記特許文献2の構成は、内窓として開き窓を設けており、メンテナンスや掃除を容易に行うことができる。 The curtain wall of Patent Document 1 degrades the exterior design of the building because the exterior of the building differs between the fireproof portion and the non-fireproof portion. Therefore, as a countermeasure, the curtain wall itself is all constructed with the same non-fireproof equipment, and fireproof measures are established in the necessary parts by installing inner windows (opening devices) with fireproof measures on the interior side. can be considered. However, when the inner window is installed on the indoor side of the curtain wall, there is a concern that dew condensation may occur in the space between the curtain wall and the inner window, or dust, insects, and the like may enter this space. Therefore, it is desirable that the inner window can be easily moved for maintenance and cleaning. In addition, the configuration of Patent Document 2 is provided with a casement window as an inner window, so that maintenance and cleaning can be easily performed.

但し、このようなメンテナンスや掃除は、年に数回程度しか行わないことが想定される。このため、内窓についても、非メンテナンス時には高い外観品質が求められる。従って、特許文献2の構成のように、内窓に一般的な窓用の開口部装置を適用すると、障子やその操作部等が外観に露出し、好ましくない。なお、このような開口部装置は、カーテンウォール用の内窓以外、すなわち通常時には開閉しないが、必要な場合に開閉させたい窓にも有用である。 However, it is assumed that such maintenance and cleaning are performed only several times a year. For this reason, the inner window is also required to have a high appearance quality during non-maintenance. Therefore, if a general window opening device is applied to the inner window as in the configuration of Patent Document 2, the shoji and its operation part are exposed to the outside, which is not preferable. It should be noted that such an opening device is also useful for windows other than interior windows for curtain walls, that is, windows that are normally not opened and closed but are desired to be opened and closed when necessary.

本発明は、上記従来技術の課題を考慮してなされたものであり、外観品質を確保しつつ、必要な場合に容易にメンテナンスを行うことができる開口部装置を提供することを目的とする。 SUMMARY OF THE INVENTION It is an object of the present invention to provide an opening device that can be easily maintained when necessary while ensuring good appearance quality.

本発明に係る開口部装置は、上枠、下枠、及び左右の縦枠で開口部を形成した枠体と、前記開口部内で前記枠体に支持される障子と、前記枠体に対して着脱可能に装着され、前記障子の框体の室内側見付け面を保持する押縁と、を備える開口部装置であって、前記枠体は、一方の縦枠の内側見込み面に、第1蝶番部品を長手方向に沿って移動可能に装着可能なポケット部を有し、前記障子は、前記一方の縦枠と対向配置される縦框の外側見込み面に、前記第1蝶番部品と回転可能に連結される第2蝶番部品を取付可能な取付孔を有し、前記ポケット部は、前記押縁によって隠されることを特徴とする。 An opening device according to the present invention includes: a frame body having an opening formed by an upper frame, a lower frame, and left and right vertical frames; a shoji screen supported by the frame body within the opening; and a rim that is detachably mounted and holds the indoor facing surface of the frame of the shoji, wherein the frame has a first hinge part on the inner side of one of the vertical frames. The shoji is rotatably connected to the first hinge part on the outer projected surface of the vertical frame arranged to face the one vertical frame. and a mounting hole for mounting the second hinge part, and the pocket portion is hidden by the ridge.

本発明によれば、外観品質を確保しつつ、必要な場合に容易にメンテナンスを行うことができる。 ADVANTAGE OF THE INVENTION According to this invention, maintenance can be easily performed when needed, ensuring appearance quality.

各框30a~30dは、それぞれ内側に開口した開口溝30eを有する。開口溝30eは、面材31の縁部を保持する部分である。図4Aに示すように、開口溝30eの開口幅Wは、面材31の板厚tよりも僅かに小さい寸法に設定されている。面材31の縁部には、R形状部31aが形成されている。これにより面材31は、その板厚tよりも狭い開口幅Wの開口溝30eに対して、R形状部31aを先頭にして円滑に挿入できる(図4B参照)。R形状部31aは、火災時の面材31の耐熱強度を向上させる機能も有する。この際、面材31の縁部はゴムや樹脂で形成された断面U字状のガスケットを介して開口溝30eに保持される。 Each of the frames 30a-30d has an opening groove 30e that opens inward. The opening groove 30 e is a portion that holds the edge of the face member 31 . As shown in FIG. 4A , the opening width W of the opening groove 30 e is set to be slightly smaller than the plate thickness t of the face member 31 . An edge portion of the face member 31 is formed with an R-shaped portion 31a. As a result, the face member 31 can be smoothly inserted into the opening groove 30e having an opening width W narrower than the plate thickness t, with the R-shaped portion 31a leading (see FIG. 4B). The R-shaped portion 31a also has a function of improving the heat resistance strength of the face material 31 in case of fire. At this time, the edge of the face member 31 is held in the opening groove 30e via a gasket having a U-shaped cross section made of rubber or resin.

障子14は、面材31の板厚tよりも開口溝30eの開口幅Wが狭いため、火災時にガスケットが焼失した場合にも開口溝30eからの面材31の脱落を抑制できる。図4A及び図4Bは、縦框30cの開口溝30eと面材31との関係を例示しているが、他の框30a,30b,30dの開口溝30eと面材31との関係も同様な構造である。 Since the opening width W of the opening groove 30e of the shoji 14 is narrower than the plate thickness t of the face material 31, it is possible to prevent the face material 31 from coming off the opening groove 30e even when the gasket is destroyed by fire. 4A and 4B exemplify the relationship between the opening groove 30e of the vertical frame 30c and the surface material 31. The relationship between the opening grooves 30e of the other frames 30a, 30b, and 30d and the surface material 31 is similar. Structure.

押縁16は、枠体12に対して室内側から開口部12eに挿入され、装着される。押縁16は、その室外側見付け面で障子14の框体30の室内側見付け面30fを保持する。障子14の室外側見付け面30gは、枠体12の室外側見付け片21で保持される。つまり押縁16は、開口溝26の室内側壁部を構成する。この際、各框30a~30dの室外側見付け面30gは、第2気密材29の室外側気密部29aと密着し、これにより障子14の室内外が気密される。 The rim 16 is inserted into the opening 12e of the frame 12 from the inside of the room and mounted thereon. The rim 16 holds the indoor facing surface 30f of the frame 30 of the shoji 14 on its outdoor facing surface. The outdoor facing surface 30 g of the shoji 14 is held by the outdoor facing piece 21 of the frame 12 . That is, the rim 16 constitutes the inner side wall portion of the opening groove 26 . At this time, the outdoor facing surface 30g of each of the frames 30a to 30d is in close contact with the outdoor airtight portion 29a of the second airtight member 29, so that the interior and exterior of the shoji 14 are airtight.

押縁16は、上縁材16a、下縁材16b、及び左右の縦縁材16c,16dを有する。各縁材16a~16bは、アルミニウム等の金属の押出形材である。図2及び図3に示す構成例では、上縁材16a及び下縁材16bは、中空部とコ字状とを合わせた断面形状を有し、左右の縦縁材16c,16dはコ字状の断面形状を有する。各縁材16a~16dは、それぞれ同一又は異なる断面形状を有する形材でもよい。各縁材16a~16dの外側見込み面には、枠外側へと突出した見込み方向で一対の爪部16eが設けられている。各縁材16a~16dは、それぞれの爪部16eが各枠12a~12dのポケット部24に係合する。これにより各縁材16a~16dは、各枠12a~12dに着脱可能に装着される。縦縁材16dの爪部16eは、後述する蝶番部品34,35,38,39に重なる部分が切り取られている。 The rim 16 has an upper edge member 16a, a lower edge member 16b, and left and right vertical edge members 16c and 16d. Each edge member 16a-16b is an extruded profile of metal such as aluminum. In the configuration example shown in FIGS. 2 and 3, the upper edge member 16a and the lower edge member 16b have a cross-sectional shape combining a hollow portion and a U-shape, and the left and right vertical edge members 16c and 16d have a U-shape. has a cross-sectional shape of Each edge member 16a-16d may be a profile member having the same or different cross-sectional shape. A pair of claw portions 16e are provided on the outer projection surface of each of the edge members 16a to 16d in the projection direction projecting to the outside of the frame. Each of the rim members 16a-16d engages with the pocket portion 24 of each of the frames 12a-12d at the respective claw portion 16e. As a result, the frame members 16a-16d are detachably attached to the frames 12a-12d. A claw portion 16e of the vertical rim member 16d is cut at portions overlapping hinge parts 34, 35, 38, and 39, which will be described later.

押縁16は、室内側からポケット部24を覆い隠し、開口部装置10の外観品質を向上させる。押縁16は、枠体12の開口部12e内に収容されるため、開口部装置10の室内側に突出せず、一層高い外観品質が得られる。 The ridge 16 hides the pocket portion 24 from the inside of the room and improves the appearance quality of the opening device 10.例文帳に追加Since the rim 16 is accommodated in the opening 12e of the frame 12, it does not protrude into the interior of the opening device 10, and a higher appearance quality can be obtained.

図2及び図3中の参照符号32は、熱膨張性部材である。熱膨張性部材32は、例えば上枠12a、縦枠12c,12dの外側見込み面20aの室内側端部と、縦枠12c,12dの内側見込み面20bと、各框30a~30dの外側見込み面と、に設けられている。熱膨張性部材32は、加熱された場合に膨張する黒鉛等によって形成された加熱発泡材である。熱膨張性部材32は、各部材の長手方向に沿って延在するように貼り付けられている。 Reference numeral 32 in FIGS. 2 and 3 is a thermal expansion member. The thermally expandable member 32 includes, for example, the indoor end portions of the outer projected surfaces 20a of the upper frame 12a and the vertical frames 12c and 12d, the inner projected surfaces 20b of the vertical frames 12c and 12d, and the outer projected surfaces of the frames 30a to 30d. and is provided. The thermally expandable member 32 is a thermally foamed material made of graphite or the like that expands when heated. The thermally expandable member 32 is attached so as to extend along the longitudinal direction of each member.

<1.2 開き窓構造の説明>
次に、開口部装置10を障子14を室内側へと内開き可能な開き窓構造とする場合の具体的な構成を説明する。
<1.2 Explanation of casement window structure>
Next, a specific configuration will be described in the case where the opening device 10 has a casement window structure in which the shoji 14 can be opened to the inside of the room.

図5A及び図5Bに示すように、開き窓構造では、枠体12の縦枠12c,12dの一方、例えば右側の縦枠12dのポケット部24に、金属製の第1蝶番部品34,35を装着する。第1蝶番部品34は、ポケット部24の上部に配設される。第1蝶番部品35は、ポケット部24の下部に配設される。第1蝶番部品34,35は、縦縁材16dの爪部16eを装着するポケット部24を兼用することで、構造の簡素化と低コスト化が図られている。 As shown in FIGS. 5A and 5B, in the casement window structure, metal first hinge parts 34 and 35 are placed in the pocket portion 24 of one of the vertical frames 12c and 12d of the frame 12, for example, the right vertical frame 12d. Installing. A first hinge component 34 is disposed on top of the pocket portion 24 . The first hinge component 35 is arranged below the pocket portion 24 . The first hinge parts 34 and 35 also serve as the pocket portion 24 for mounting the claw portion 16e of the longitudinal edge member 16d, thereby simplifying the structure and reducing the cost.

図5Aに示すように、上側の第1蝶番部品34は、ポケット部24の上部に装着され、上下2段に調整可能である。第1蝶番部品34は、円柱部34aと、係合板34bと、第1ピン34cと、を有する。円柱部34aは、上下方向に延びた棒状部材である。円柱部34aは、ポケット部24の見込み幅よりも小さい外径を有する。 As shown in FIG. 5A, the upper first hinge component 34 is attached to the upper portion of the pocket portion 24 and can be adjusted in two steps, upper and lower. The first hinge component 34 has a cylindrical portion 34a, an engaging plate 34b and a first pin 34c. The cylindrical portion 34a is a rod-shaped member extending vertically. The cylindrical portion 34a has an outer diameter smaller than the expected width of the pocket portion 24. As shown in FIG.

係合板34bは、第1蝶番部品34の縦枠12dに対する取付部である。係合板34bは、ポケット部24に上下にスライド可能な状態で係合される。係合板34bは、例えば円柱部34aの外周面に固定され、見込み方向に幅広な板状部材である。図3に示すように、係合板34bの見込み幅は、ポケット部24の見込み幅よりも僅かに小さい。係合板34bの板厚は、ポケット部24の深さよりも僅かに小さい。これにより係合板34bは、ポケット部24の狭幅な開口縁部に保持された状態でポケット部24に上下動可能に係合できる。 The engagement plate 34b is an attachment portion of the first hinge part 34 to the vertical frame 12d. The engagement plate 34b is engaged with the pocket portion 24 so as to be vertically slidable. The engagement plate 34b is, for example, a plate-shaped member that is fixed to the outer peripheral surface of the cylindrical portion 34a and that is wide in the projection direction. As shown in FIG. 3, the expected width of the engaging plate 34b is slightly smaller than the expected width of the pocket portion 24. As shown in FIG. The plate thickness of the engaging plate 34b is slightly smaller than the depth of the pocket portion 24. As shown in FIG. As a result, the engaging plate 34b can be engaged with the pocket portion 24 so as to be vertically movable while being held by the narrow opening edge portion of the pocket portion 24. As shown in FIG.

係合板34bの下部からは、取付板34dが突出している。取付板34dは、板厚方向の貫通孔を有し、ねじ36でポケット部24の底面に形成された上下のねじ穴24a,24bの一方に選択的に締結される。上のねじ穴24aは、障子14の開閉時に利用される。下のねじ穴24bは、障子14の開閉が不要な通常時に利用される。これにより、第1蝶番部品34は、上下方向にスライドさせて位置調整し、2段の高さ位置で縦枠12dに固定できる。 A mounting plate 34d protrudes from the lower portion of the engaging plate 34b. The mounting plate 34 d has a through hole extending in the plate thickness direction, and is selectively fastened to one of the upper and lower screw holes 24 a and 24 b formed in the bottom surface of the pocket portion 24 with a screw 36 . The upper screw hole 24a is used when the shoji 14 is opened and closed. The lower screw hole 24b is used normally when opening and closing the shoji 14 is unnecessary. As a result, the first hinge component 34 can be vertically slid to adjust its position and fixed to the vertical frame 12d at two height positions.

第1ピン34cは、円柱部34aの上端面から上方に突出したシャフトである。第1ピン34cは、障子14の回転軸として機能する。 The first pin 34c is a shaft protruding upward from the upper end surface of the cylindrical portion 34a. The first pin 34 c functions as a rotating shaft of the shoji 14 .

図5Bに示すように、下側の第1蝶番部品35は、ポケット部24の下部に装着される。第1蝶番部品35は、第1筒体35aと、係合板35bと、を有する。第1筒体35aは、上下方向に延びた筒状部材である。第1筒体35aは、円柱部34aと略同一の外径を有し、縦縁材16d内に収容可能である(図3参照)。第1筒体35aには、上下方向に沿った軸孔35cが形成されている。軸孔35cには、第2ピン37(図7B参照)が回転可能に挿入される。 As shown in FIG. 5B, the lower first hinge component 35 is attached to the lower portion of the pocket portion 24 . The first hinge component 35 has a first cylindrical body 35a and an engaging plate 35b. The first tubular body 35a is a tubular member extending in the vertical direction. The first cylindrical body 35a has substantially the same outer diameter as the columnar portion 34a, and can be accommodated in the vertical rim member 16d (see FIG. 3). A shaft hole 35c extending in the vertical direction is formed in the first cylindrical body 35a. A second pin 37 (see FIG. 7B) is rotatably inserted into the shaft hole 35c.

係合板35bは、第1筒体35aの外周面に固定されている。係合板35bは、上側の第1蝶番部品34の係合板34bと上下方向長さが多少異なる以外は同一形状及び同一機能を有するため、詳細な説明は省略する。第1蝶番部品35は、ポケット部24の下端部に装着されるため、縦枠12dに固定しなくても下枠12bの内側見込み面20bに当接して上下方向に位置決めされる。第1蝶番部品35は、ねじ止め等によって縦枠12dに固定してもよい。 The engagement plate 35b is fixed to the outer peripheral surface of the first cylindrical body 35a. The engaging plate 35b has the same shape and the same function as the engaging plate 34b of the upper first hinge component 34 except that the length in the vertical direction is slightly different, so detailed description thereof will be omitted. Since the first hinge component 35 is attached to the lower end of the pocket portion 24, it is positioned vertically by coming into contact with the inner projected surface 20b of the lower frame 12b without being fixed to the vertical frame 12d. The first hinge part 35 may be fixed to the vertical frame 12d by screwing or the like.

図6A及び図6Bに示すように、開き窓構造では、障子14の縦框30c,30dの一方、例えば右側の縦框30dに、金属製の第2蝶番部品38、39を装着する。第2蝶番部品38は、縦框30dの外側見込み面30hの上端部に固定される。第2蝶番部品39は、縦框30dの外側見込み面30hの下端部に固定される。 As shown in FIGS. 6A and 6B, in the casement window structure, metal second hinge parts 38 and 39 are attached to one of the vertical frames 30c and 30d of the shoji 14, for example, the right vertical frame 30d. The second hinge component 38 is fixed to the upper end of the outer projection surface 30h of the vertical frame 30d. The second hinge part 39 is fixed to the lower end of the outer projection surface 30h of the vertical frame 30d.

図6Aに示すように、上側の第2蝶番部品38は、第2筒体38aと、取付板38bと、を有する。第2筒体38aには、上下方向に沿った軸孔38cが形成されている。第2筒体38a及び軸孔38cは、第1蝶番部品35の第1筒体35a及び軸孔35cと同一形状でよい。軸孔38cには、第1ピン34cが回転可能に挿入される。 As shown in FIG. 6A, the upper second hinge component 38 has a second tubular body 38a and a mounting plate 38b. A shaft hole 38c extending in the vertical direction is formed in the second cylindrical body 38a. The second cylinder 38 a and the shaft hole 38 c may have the same shape as the first cylinder 35 a and the shaft hole 35 c of the first hinge part 35 . A first pin 34c is rotatably inserted into the shaft hole 38c.

取付板38bは、第2蝶番部品38の縦框30dに対する取付部である。取付板38bは、第2筒体38aの外周面から外径方向に突出した板状部材である。取付板38bは、上下2段の貫通孔が形成されており、各貫通孔にそれぞれねじ40が挿通される。ねじ40は、縦框30dを上框30aに固定するためのねじである。つまり取付板38bは、ねじ40を用いて縦框30dと共に上框30aに共締めされ、これにより第2蝶番部品38が縦框30dに固定される。 The mounting plate 38b is a mounting portion of the second hinge part 38 to the vertical frame 30d. The mounting plate 38b is a plate-like member protruding radially outward from the outer peripheral surface of the second cylindrical body 38a. The mounting plate 38b is formed with two upper and lower through-holes, and screws 40 are inserted through the respective through-holes. The screw 40 is a screw for fixing the vertical frame 30d to the upper frame 30a. That is, the mounting plate 38b is fastened together with the vertical frame 30d to the upper frame 30a using the screws 40, thereby fixing the second hinge component 38 to the vertical frame 30d.

図6Bに示すように、下側の第2蝶番部品39は、第2筒体39aと、取付板39bと、を有する。第2筒体39aには、上下方向に沿った軸孔39cが形成されている。第2蝶番部品39の第2筒体39a、取付板39b、軸孔39cは、上記した第2蝶番部品38の第2筒体38a、取付板38b、軸孔38cと上下対称形状である以外は基本的に同一構造である。なお、取付板39bは、取付板38bと同様なねじ40を用いて縦框30dと共に下框30bに共締めされる。軸孔39cには、第2ピン37が挿入される。第2筒体39aの外周面には、軸孔39cまで貫通したねじ孔39dが形成されている。ねじ孔39dには、第2ピン37を固定するねじ39eが螺合される。ねじ39eは、いもねじやホーローセットと呼ばれる止めねじである。 As shown in FIG. 6B, the lower second hinge component 39 has a second tubular body 39a and a mounting plate 39b. A shaft hole 39c extending in the vertical direction is formed in the second cylindrical body 39a. The second cylinder 39a, the mounting plate 39b, and the shaft hole 39c of the second hinge part 39 are vertically symmetrical with the second cylinder 38a, the mounting plate 38b, and the shaft hole 38c of the second hinge part 38. They have basically the same structure. The mounting plate 39b is fastened together with the vertical frame 30d to the lower frame 30b using screws 40 similar to those used for the mounting plate 38b. A second pin 37 is inserted into the shaft hole 39c. A screw hole 39d penetrating to the shaft hole 39c is formed in the outer peripheral surface of the second cylindrical body 39a. A screw 39e for fixing the second pin 37 is screwed into the screw hole 39d. The screw 39e is a set screw called a set screw or hollow set.

図7Aに示すように、第1蝶番部品34は、その上に第2蝶番部品38が配置され、軸孔38cに第1ピン34cが挿入される。これにより上側の蝶番部品34,38は、1つの蝶番として機能する。図7Bに示すように、第1蝶番部品35は、その上に第2蝶番部品39が配置され、軸孔39c,35cに第2ピン37が上から連続して挿入され、ねじ39eによって第2蝶番部品39が第2ピン37と固定される。これにより下側の蝶番部品35,39も、1つの蝶番として機能する。その結果、開口部装置10は、上下2つの蝶番で障子14を枠体12に対して開閉可能に支持した状態となる。 As shown in FIG. 7A, the first hinge part 34 has the second hinge part 38 disposed thereon and the first pin 34c is inserted into the axial hole 38c. The upper hinge parts 34, 38 thereby function as one hinge. As shown in FIG. 7B, the first hinge part 35 has the second hinge part 39 arranged thereon, the second pin 37 is continuously inserted into the shaft holes 39c, 35c from above, and the second hinge part 35 is screwed by the screw 39e. A hinge part 39 is fixed with the second pin 37 . As a result, the lower hinge parts 35, 39 also function as one hinge. As a result, the opening device 10 is in a state in which the shoji 14 is supported so as to be openable and closable with respect to the frame 12 by two upper and lower hinges.

<1.3 障子の開閉動作の説明>
次に、開き窓構造での障子14の開閉動作を説明する。
<1.3 Explanation of opening and closing operation of shoji>
Next, the opening and closing operation of the shoji 14 in the casement window structure will be described.

先ず、障子14の開閉動作の説明に先立ち、障子14の開閉が不要な通常時の状態を説明する。開口部装置10は、障子14の開閉が不要な通常時には、図8Aに示すように、上側の第1蝶番部品34を下段のねじ穴24bで固定し、第1ピン34cを第2蝶番部品38の軸孔38cから抜去しておく。また、図8Aに示すように、下側の第2ピン37は、軸孔35c,39cから抜去し、別途保管しておく。さらに、各枠12a~12dには、押縁16の各縁材16a~16dを装着し、障子14を保持しておく。その結果、蝶番部品34,35,38,39は、通常時、押縁16で覆い隠され(図9参照)、開口部装置10の外観に露出しない。このため、開口部装置10は、通常時、蝶番部品34等が外観に露出せず、高い外観品質が得られる。 First, before explaining the opening and closing operation of the shoji 14, the normal state in which the opening and closing of the shoji 14 is unnecessary will be described. In the opening device 10, when the shoji 14 does not need to be opened and closed normally, as shown in FIG. is withdrawn from the shaft hole 38c. Further, as shown in FIG. 8A, the lower second pin 37 is removed from the shaft holes 35c and 39c and stored separately. Furthermore, the frame members 16a to 16d of the rim 16 are attached to the frames 12a to 12d to hold the shoji 14. As shown in FIG. As a result, hinge parts 34 , 35 , 38 , 39 are normally hidden by ledge 16 (see FIG. 9 ) and are not exposed to the exterior of opening device 10 . Therefore, in the opening device 10, the hinge parts 34 and the like are not normally exposed to the outside, and a high appearance quality can be obtained.

また、この状態では、各ピン34c,37が軸孔38c,35c,39cから抜去され、障子14が枠体12に拘束されていない。その結果、開口部装置10は、通常時に地震等の影響で層間変位が生じた際、障子14がフリーな状態にあるため、建物躯体からの外力が枠体12を介して框体30に作用し、面材31が破損することが抑制される。 Also, in this state, the pins 34c, 37 are removed from the shaft holes 38c, 35c, 39c, and the shoji 14 is not restrained by the frame 12. As shown in FIG. As a result, in the opening device 10, when an inter-story displacement occurs under the influence of an earthquake or the like in normal times, the shoji 14 is in a free state. As a result, damage to the face material 31 is suppressed.

次に、例えば外窓であるカーテンウォール18と内窓である開口部装置10との間の空間のメンテナンスや掃除を行うために、障子14を開閉する必要がある場合は、先ず、押縁16を取り外す。次いで、図8Bに示すように、第1蝶番部品34は、ねじ36を下段のねじ穴24bから外して上に移動させ、上段のねじ穴24aで縦枠12dに固定する。この際、第1ピン34cは、第2蝶番部品38の軸孔38cに下から挿入する。さらに、図8A中に1点鎖線で示す矢印のように、第2ピン37は、上下に並んだ蝶番部品39,35の軸孔39c,35cに上から挿入する。その結果、各蝶番部品34,38及び35,39がそれぞれ1つの蝶番を構成し、障子14は各ピン34c,37を回転軸として回動可能な状態となる。そこで、障子14は、蝶番部品34等と逆側の縦框30c側を室内側に引き寄せることで、容易に開閉することができる(図7A及び図7B参照)。なお、本実施形態の開口部装置10は、障子14が相当な重量物である。このため、障子14は、開いた際、下框30bと建物の床面等との間に、その重量を受け止めるブロック材等を配置するとよい。 Next, when it is necessary to open and close the shoji 14 in order to maintain or clean the space between the curtain wall 18, which is an outer window, and the opening device 10, which is an inner window, for example, the rim 16 is first removed. Remove. Next, as shown in FIG. 8B, the first hinge part 34 is fixed to the vertical frame 12d by removing the screw 36 from the lower threaded hole 24b, moving it upward, and fixing it to the vertical frame 12d with the upper threaded hole 24a. At this time, the first pin 34c is inserted into the shaft hole 38c of the second hinge part 38 from below. 8A, the second pin 37 is inserted from above into the shaft holes 39c, 35c of the vertically aligned hinge parts 39, 35, as indicated by the dashed-dotted arrows. As a result, each of the hinge parts 34, 38 and 35, 39 constitutes one hinge, and the shoji 14 becomes rotatable about the pins 34c, 37 as the rotation axis. Therefore, the shoji 14 can be easily opened and closed by pulling the vertical frame 30c side opposite to the hinge parts 34 and the like to the indoor side (see FIGS. 7A and 7B). It should be noted that the shoji 14 of the opening device 10 of the present embodiment is quite heavy. For this reason, when the shoji 14 is opened, it is preferable to arrange a block material or the like to receive the weight between the lower frame 30b and the floor of the building or the like.

ところで、開口部装置10は、上記の通り、開き窓構造を採用しない嵌め殺し構造(FIX構造)として施工することもできる。開口部装置10は、嵌め殺し構造とする場合には、蝶番部品34,35,38,39を上記した開き窓構造から省略するだけでよい。つまりこの構成では、第1蝶番部品34,35をポケット部24に装着せず、第2蝶番部品38,39を框体30の組立時にねじ40で固定しないだけで、容易に嵌め殺し構造が構築される。嵌め殺し構造の開口部装置10は、カーテンウォール18と開口部装置10との間の空間のメンテナンスや掃除を行う場合には、先ず押縁16を取り外す。次に、障子14は、所定の吸盤器具等を利用して持ち上げて室内側に移動させ、枠体12から抜き取ればよい。このように、本実施形態の開口部装置10は、蝶番部品34等を除くほとんどの部品を共用して、開き窓構造と嵌め殺し構造との2つの仕様を選択的に構成できるため、高い汎用性が得られ、部品コスト及び製造コストを低減できる。 By the way, as described above, the opening device 10 can also be constructed as a non-fitting structure (FIX structure) without adopting the casement structure. If the opening device 10 were to be of a mating construction, the hinge parts 34, 35, 38, 39 would simply be omitted from the casement construction described above. In other words, in this configuration, the fitting structure can be easily constructed simply by not attaching the first hinge parts 34 and 35 to the pocket portion 24 and fixing the second hinge parts 38 and 39 with the screws 40 when assembling the frame body 30. be done. For the one-to-one opening assembly 10, the ledge 16 is first removed when the space between the curtain wall 18 and the opening assembly 10 is to be maintained or cleaned. Next, the shoji 14 can be lifted using a predetermined sucker or the like, moved into the room, and removed from the frame 12 . In this way, the opening device 10 of the present embodiment shares most of the parts except for the hinge part 34 and the like, and can selectively configure two specifications, the casement window structure and the fitted structure, so that it is highly versatile. This results in reduced parts and manufacturing costs.

<2.開口部装置の施工時の納まり構造の説明>
次に、開口部装置10の建物での施工構造の一例を説明する。本実施形態の開口部装置10は、建物の仕様やユーザの要望に応じて、2つの納まり(露出配置、隠蔽配置)に兼用できる。開口部装置10は、防火仕様を有することにより、非防火仕様の外窓であるカーテンウォール18の内窓として、延焼の可能性のある位置に適宜施工される。カーテンウォール18は、複数のユニットが左右に並列されるため、開口部装置10も必要に応じて左右に並んで施工される。
<2. Explanation of fitting structure at the time of construction of opening device>
Next, an example of construction structure of the opening device 10 in a building will be described. The opening device 10 of the present embodiment can be used in two ways (exposed arrangement and concealed arrangement) depending on the specifications of the building and user's request. Since the opening device 10 has a fireproof specification, it is appropriately constructed as an inner window of the curtain wall 18, which is a non-fireproof exterior window, at a position where a fire may spread. Since a plurality of units are arranged side by side in the curtain wall 18, the opening devices 10 are also arranged side by side as required.

<2.1 露出配置の説明>
先ず、露出配置について説明する。図10A~図10Dに示すように、建物42は、外窓であるカーテンウォール18の室内側に、内窓である開口部装置10を設置した構成である。カーテンウォール18は、2層の面材18a,18bの四周を上下左右の外窓枠43や縦材となる方立48で保持した構成である。外窓枠43及び方立48は、建物42の壁等の躯体42aに対してファスナー44を利用して固定される。露出配置では、開口部装置10は、外窓枠43の枠内側に張り出した位置に配置される。
<2.1 Description of Exposure Arrangement>
First, the exposed arrangement will be described. As shown in FIGS. 10A to 10D, the building 42 has a configuration in which the opening device 10, which is an inner window, is installed on the indoor side of the curtain wall 18, which is an outer window. The curtain wall 18 has a configuration in which four layers of face members 18a and 18b are held by upper, lower, left, and right outer window frames 43 and mullions 48 serving as vertical members. The outer window frame 43 and the mullion 48 are fixed to the frame 42a such as the wall of the building 42 using fasteners 44 . In the exposed configuration, the opening device 10 is located in a position overhanging the frame inside of the exterior window frame 43 .

開口部装置10は、躯体42aに固定された下地材46(図10A~図10C参照)と、外窓枠43と連結された方立48(図10D参照)とに取り付けられる。下地材46は、躯体42aと固定された躯体部材である。方立48は、左右に並んだカーテンウォール18の各ユニット間を仕切る躯体部材であり、例えばアルミニウムの押出形材である。方立48は、上下の枠部43a,43b間に連結され、ファスナー44を介して連結される。図10A~図10C中の参照符号50は、額縁部材(膳板)である。 The opening device 10 is attached to a base material 46 (see FIGS. 10A to 10C) fixed to the frame 42a and a mullion 48 (see FIG. 10D) connected to the outer window frame 43. The base material 46 is a frame member fixed to the frame 42a. The mullion 48 is a frame member that partitions between the units of the curtain wall 18 arranged on the left and right, and is, for example, an extruded shape of aluminum. The mullion 48 is connected between the upper and lower frame portions 43 a and 43 b and connected via the fastener 44 . Reference numeral 50 in FIGS. 10A to 10C denotes a frame member (table plate).

図10A~図10Dに示すように、露出配置において、枠体12は、第1取付部25aを用いて躯体部材に取り付ける。図10Aに示すように、上枠12aは、外側見込み面20aを天井側の下地材46の見込み面に額縁部材50を挟んで突き当てる。さらに上枠12aは、室外側見付け片21を外窓枠43の左右の縦枠部43c,43dの室内側見付け面52に突き当てる。上枠12aは、第1取付孔20cを介して壁部20をねじ27で下地材46に締結することで、下地材46を介して躯体42aと固定される。 As shown in Figures 10A-10D, in the exposed configuration, the frame 12 is attached to the body member using first attachment portions 25a. As shown in FIG. 10A, the upper frame 12a abuts the outer prospective surface 20a against the prospective surface of the base material 46 on the ceiling side with the frame member 50 interposed therebetween. Furthermore, the upper frame 12a abuts the outdoor side facing piece 21 against the indoor side facing surfaces 52 of the left and right vertical frame portions 43c and 43d of the outside window frame 43. As shown in FIG. The upper frame 12a is fixed to the frame 42a via the base material 46 by fastening the wall portion 20 to the base material 46 with screws 27 through the first attachment holes 20c.

図10Bに示すように、下枠12bは、外側見込み面20aを床側の下地材46の見込み面に額縁部材50を挟んで突き当てる。さらに下枠12bは、室外側見付け片21を外窓枠43の縦枠部43c,43dの室内側見付け面52に突き当てる。下枠12bは、第1取付孔20cを介して壁部20をねじ27で下地材46に締結することで、下地材46を介して躯体42aと固定される。 As shown in FIG. 10B, the lower frame 12b abuts the outer prospective surface 20a against the prospective surface of the base member 46 on the floor side with the frame member 50 interposed therebetween. Furthermore, the lower frame 12b abuts the outdoor side facing piece 21 against the indoor side facing surface 52 of the vertical frame portions 43c and 43d of the outer window frame 43. As shown in FIG. The lower frame 12b is fixed to the frame 42a via the base material 46 by fastening the wall portion 20 to the base material 46 with screws 27 through the first attachment holes 20c.

図10C及び図10Dに示すように、縦枠12c,12dは、その施工される位置により、下地材46を介して躯体42aと固定される場合(第1露出配置)と、方立48に固定される場合(第2露出配置)とがある。縦枠12dの施工状態は図示していないが、図10C及び図10Dに示す縦枠12cと左右対称構造である以外は同一でよい。 As shown in FIGS. 10C and 10D, the vertical frames 12c and 12d are fixed to the frame 42a via the base material 46 (first exposed arrangement) or fixed to the mullion 48, depending on the position where they are constructed. There is a case (second exposed arrangement). Although the construction state of the vertical frame 12d is not illustrated, it may be the same as the vertical frame 12c shown in FIGS. 10C and 10D except that it has a bilaterally symmetrical structure.

図10Cに示すように、第1露出配置の縦枠12c(12d)は、外側見込み面20aを側壁側の下地材46の見込み面に額縁部材50を挟んで突き当てる。さらに縦枠12c(12d)は、室外側見付け片21を外窓枠43の下枠部43bの室内側見付け面53及び縦枠部43c,43dの室内側見付け面52に突き当てる。縦枠12c(12d)は、第1取付孔20cを介して壁部20をねじ27で下地材46に締結することで、下地材46を介して躯体42aと固定される。 As shown in FIG. 10C, the vertical frame 12c (12d) in the first exposed arrangement abuts the projected outer surface 20a against the projected surface of the base material 46 on the sidewall side with the frame member 50 interposed therebetween. Further, the vertical frame 12c (12d) abuts the outdoor facing piece 21 against the indoor facing surface 53 of the lower frame portion 43b of the outer window frame 43 and the indoor facing surfaces 52 of the vertical frame portions 43c and 43d. The vertical frame 12c (12d) is fixed to the frame 42a via the base material 46 by fastening the wall part 20 to the base material 46 with screws 27 through the first mounting holes 20c.

図10Dに示すように、第2露出配置の縦枠12c(12d)は、方立48の内側見込み面48aの側部に配置される。縦枠12c(12d)は、外側見込み面20aを方立48の内側見込み面48aに突き当てる。縦枠12c(12d)は、第1取付孔20cを介して壁部20をねじ27で方立48に締結することで、躯体部材である方立48と固定される。 As shown in FIG. 10D, the vertical frame 12c (12d) of the second exposed arrangement is arranged on the side of the inner projection surface 48a of the mullion 48. As shown in FIG. The vertical frame 12 c ( 12 d ) abuts the outer projection surface 20 a against the inner projection surface 48 a of the mullion 48 . The vertical frame 12c (12d) is fixed to the mullion 48, which is a frame member, by fastening the wall portion 20 to the mullion 48 with screws 27 through the first mounting holes 20c.

このように、露出配置では、特に図10Dに示す方立48との取付部において、開口部装置10が室内側に張り出すことがない。このため、開口部装置10が、建物42の内観を損なうことを抑制できる。このような露出配置において、上枠12a及び下枠12bと外窓枠43との間は、第2気密材29の室外側気密部29aが室内側見付け面52に密着することで室内外に気密される(図10A及び図10B参照)。また、第1露出配置の縦枠12c(12d)は、壁部20の外側見込み面20aから突出した第1気密材23が、室内側見付け面53及び額縁部材50に密着することで室内外に気密される(図10C参照)。さらに、第2露出配置の縦枠12c(12d)は、壁部20の外側見込み面20aから突出した第1気密材23が、方立48の内側見込み面48aに密着することで室内外に気密される(図10D参照)。 Thus, in the exposed arrangement, the opening device 10 does not protrude into the room, particularly at the attachment to the mullion 48 shown in FIG. 10D. Therefore, it is possible to prevent the opening device 10 from impairing the interior appearance of the building 42 . In such an exposed arrangement, between the upper frame 12a and the lower frame 12b and the outer window frame 43, the outdoor-side airtight portion 29a of the second airtight member 29 is in close contact with the indoor-side viewing surface 52, thereby airtightly airtight to the inside and outside of the room. (see FIGS. 10A and 10B). In addition, the vertical frame 12c (12d) of the first exposed arrangement has the first airtight member 23 protruding from the outer projected surface 20a of the wall portion 20, which is in close contact with the interior facing surface 53 and the frame member 50. It is hermetically sealed (see FIG. 10C). Further, the vertical frame 12c (12d) of the second exposed arrangement is airtight both indoors and outdoors by the first airtight member 23 protruding from the outer projected surface 20a of the wall portion 20 closely contacting the inner projected surface 48a of the mullion 48. (see FIG. 10D).

<2.2 隠蔽配置の説明>
次に、隠蔽配置について説明する。図11A~図11Dに示すように、隠蔽配置では、開口部装置10は、外窓枠43の室内側に隠された位置に配置される。上記した露出配置と同様、隠蔽配置においても、開口部装置10は、下地材46(図11A~図11C参照)と、方立48(図11D参照)と、に取り付けられる。
<2.2 Description of Concealment Arrangement>
Next, the hidden arrangement will be described. As shown in FIGS. 11A-11D, in the concealed configuration, the opening device 10 is located in a concealed position on the interior side of the exterior window frame 43 . Similar to the exposed configuration described above, in the concealed configuration, aperture device 10 is attached to substrate 46 (see FIGS. 11A-11C) and mullion 48 (see FIG. 11D).

図11A及び図11Bに示すように、隠蔽配置において、上枠12a及び下枠12bは、第1取付部25aを用いて躯体部材に取り付ける。図11Aに示すように、上枠12aは、外側見込み面20aを天井側の下地材46の見込み面に突き当てる。さらに上枠12aは、室外側見付け片21を外窓枠43の上枠部43aの室内側見付け面54に突き当てる。上枠12aは、第1取付孔20cを介して壁部20をねじ27で下地材46に締結することで、下地材46を介して躯体42aと固定される。これにより上枠12aは、その大部分が外窓枠43の上枠部43aの室内側に隠され、室外側見付け片21の先端側の一部のみが僅かに上枠部43aよりも枠内側に張り出した隠蔽状態で設置される。 As shown in FIGS. 11A and 11B, in the concealed arrangement, the upper frame 12a and the lower frame 12b are attached to the frame member using first attachment portions 25a. As shown in FIG. 11A, the upper frame 12a abuts the projected outer surface 20a against the projected surface of the base material 46 on the ceiling side. Further, the upper frame 12 a abuts the outdoor side facing piece 21 against the indoor facing side 54 of the upper frame portion 43 a of the outside window frame 43 . The upper frame 12a is fixed to the frame 42a via the base material 46 by fastening the wall portion 20 to the base material 46 with screws 27 through the first attachment holes 20c. As a result, most of the upper frame 12a is hidden inside the upper frame portion 43a of the outer window frame 43, and only a portion of the front end side of the outdoor side tab 21 is slightly inside the upper frame portion 43a. It is installed in a concealed state overhanging.

図11Bに示すように、下枠12bは、外側見込み面20aを床側の下地材46の見込み面に突き当てる。さらに下枠12bは、室外側見付け片21を外窓枠43の下枠部43bの室内側見付け面53及び縦枠部43c,43dの室内側見付け面52に突き当てる。下枠12bは、第1取付孔20cを介して壁部20をねじ27で下地材46に締結することで、下地材46を介して躯体42aと固定される。これにより下枠12bは、その大部分が外窓枠43の下枠部43bの室内側に隠され、室外側見付け片21の先端側の一部のみが僅かに下枠部43bよりも枠内側に張り出した隠蔽状態で設置される。 As shown in FIG. 11B, the lower frame 12b abuts the projected outer surface 20a against the projected surface of the substrate 46 on the floor side. Further, the lower frame 12b abuts the outdoor facing piece 21 against the indoor facing surface 53 of the lower frame portion 43b of the outer window frame 43 and the indoor facing surfaces 52 of the vertical frame portions 43c and 43d. The lower frame 12b is fixed to the frame 42a via the base material 46 by fastening the wall portion 20 to the base material 46 with screws 27 through the first attachment holes 20c. As a result, most of the lower frame 12b is hidden inside the lower frame portion 43b of the outer window frame 43, and only a portion of the front end side of the outdoor side tab 21 is slightly inside the lower frame portion 43b. It is installed in a concealed state overhanging.

図11C及び図11Dに示すように、隠蔽配置においても、縦枠12c,12dは、その施工される位置により、下地材46を介して躯体42aと固定される場合(第1隠蔽配置)と、方立48に固定される場合(第2隠蔽配置)とがある。縦枠12dの施工状態は図示していないが、図11C及び図11Dに示す縦枠12cと左右対称構造である以外は同一でよい。 As shown in FIGS. 11C and 11D, even in the concealed arrangement, the vertical frames 12c and 12d are fixed to the frame 42a via the base material 46 depending on the construction position (first concealed arrangement), It may be fixed to the mullion 48 (second hidden arrangement). Although the construction state of the vertical frame 12d is not illustrated, it may be the same as the vertical frame 12c shown in FIGS. 11C and 11D except that it has a symmetrical structure.

図11Cに示すように、第1隠蔽配置において、縦枠12c(12d)は、第1取付部25aを用いて躯体部材に取り付ける。第1隠蔽配置の縦枠12c(12d)は、外側見込み面20aを側壁側の下地材46の見込み面に突き当てる。さらに縦枠12c(12d)は、室外側見付け片21を下枠部43bの室内側見付け面53及び縦枠部43c,43dの室内側見付け面52に突き当てる。縦枠12c(12d)は、第1取付孔20cを介して壁部20をねじ27で下地材46に締結することで、下地材46を介して躯体42aと固定される。これにより第1隠蔽配置の縦枠12c(12d)は、略全体が外窓枠43の縦枠部43c(43d)の室内側に隠蔽された状態で設置される。 As shown in FIG. 11C, in the first concealed arrangement, the vertical frame 12c (12d) is attached to the frame member using the first attachment portion 25a. The vertical frame 12c (12d) of the first concealed arrangement abuts the projected outer surface 20a against the projected surface of the base member 46 on the sidewall side. Further, the vertical frame 12c (12d) abuts the outdoor facing piece 21 against the indoor facing surface 53 of the lower frame portion 43b and the indoor facing surfaces 52 of the vertical frame portions 43c and 43d. The vertical frame 12c (12d) is fixed to the frame 42a via the base material 46 by fastening the wall part 20 to the base material 46 with screws 27 through the first mounting holes 20c. As a result, the vertical frame 12c (12d) of the first concealed arrangement is installed in a state where substantially the entirety is concealed inside the vertical frame portion 43c (43d) of the exterior window frame 43. As shown in FIG.

図11Dに示すように、第2隠蔽配置において、縦枠12c(12d)は、第2取付部25bを用いて躯体部材に取り付ける。第2隠蔽配置の縦枠12c(12d)は、方立48の室内側見付け面48bの室内側に配置される。縦枠12c(12d)は、室外側見付け片21の室外側見付け面を方立48の室内側見付け面48bに当てる。縦枠12c(12d)は、第2取付孔21aを介して室外側見付け片21をねじ27で方立48に締結することで、躯体部材である方立48と固定される。これにより第2隠蔽配置の縦枠12c(12d)は、略全体が方立48の室内側に隠蔽された状態で設置される。なお、図11D中の参照符号56は、縦枠12c(12d)を覆い隠すカバー部材である。参照符号57は、カバー部材56の一端部を支持する支持部材である。 As shown in FIG. 11D, in the second concealed arrangement, the vertical frame 12c (12d) is attached to the frame member using the second attachment portion 25b. The vertical frame 12 c ( 12 d ) of the second concealed arrangement is arranged on the indoor side of the indoor-side facing surface 48 b of the mullion 48 . The vertical frame 12 c ( 12 d ) brings the outdoor facing surface of the outdoor facing piece 21 into contact with the indoor facing surface 48 b of the mullion 48 . The vertical frame 12c (12d) is fixed to the mullion 48, which is a frame member, by fastening the outdoor side facing piece 21 to the mullion 48 with screws 27 through the second mounting holes 21a. As a result, the vertical frame 12 c ( 12 d ) of the second concealed arrangement is installed in such a state that substantially the entirety thereof is concealed inside the mullion 48 . Reference numeral 56 in FIG. 11D denotes a cover member that covers the vertical frame 12c (12d). Reference numeral 57 is a support member that supports one end of the cover member 56 .

このように、隠蔽配置では、内窓の枠体12が、外窓の外窓枠43の室内側に隠蔽された状態で配置される。このため、開口部装置10は、枠体12や框体30がカーテンウォール18の面材18a,18b越しに建物42の外部から視認されることが抑制される。その結果、建物42の外観品質が向上する。また、開口部装置10は、枠体12や框体30が外窓枠43で隠されることで、露出配置よりも面材31の開口面積が拡大するという利点もある。このような隠蔽配置において、上枠12a及び下枠12bと外窓枠43との間は、第2気密材29の室外側気密部29aが室内側見付け面52に密着することで室内外に気密される(図11A及び図11B参照)。また、第1露出配置の縦枠12c(12d)は、壁部20の外側見込み面20aから突出した第1気密材23が、室内側見付け面53及び額縁部材50に密着することで室内外に気密される(図11C参照)。さらに、第2露出配置の縦枠12c(12d)は、第2気密材29の室外側気密部29aが、方立48の室内側見付け面48bに密着することで室内外に気密される(図11D参照)。 Thus, in the concealed arrangement, the frame 12 of the inner window is arranged in a concealed state on the indoor side of the outer window frame 43 of the outer window. Therefore, the opening device 10 prevents the frame 12 and the frame 30 from being seen from the outside of the building 42 through the panel members 18 a and 18 b of the curtain wall 18 . As a result, the appearance quality of the building 42 is improved. In addition, the opening device 10 has the advantage that the opening area of the face member 31 is enlarged as compared with the exposed arrangement because the frame 12 and the frame 30 are hidden by the outer window frame 43 . In such a concealed arrangement, between the upper frame 12a and the lower frame 12b and the outer window frame 43, the outdoor-side airtight portion 29a of the second airtight member 29 is in close contact with the indoor-side viewing surface 52, so that the room is airtight to the outside. (see FIGS. 11A and 11B). In addition, the vertical frame 12c (12d) of the first exposed arrangement has the first airtight member 23 protruding from the outer projected surface 20a of the wall portion 20, which is in close contact with the interior facing surface 53 and the frame member 50. It is hermetically sealed (see FIG. 11C). Further, the vertical frame 12c (12d) of the second exposed arrangement is airtight to the inside and outside of the room when the outdoor side airtight portion 29a of the second airtight member 29 is in close contact with the indoor side face 48b of the mullion 48 (Fig. 11D).

<2.3 コーナー部での露出配置及び隠蔽配置の説明>
次に、建物42のコーナー部での開口部装置10の納まり構造の一例を説明する。コーナー部は、例えば図12に示すように隣接する開口部装置10同士が出隅を形成する配置(出隅配置)と、図13に示すように隣接する開口部装置10同士が入隅を形成する配置(入隅配置)とが想定される。
<2.3 Explanation of Exposed Arrangement and Concealed Arrangement at Corner>
Next, an example of the fitting structure of the opening device 10 at the corner of the building 42 will be described. For example, as shown in FIG. 12, adjacent opening devices 10 form external corners (external corner arrangement), and as shown in FIG. 13, adjacent opening devices 10 form internal corners. (inside corner arrangement) is assumed.

図12に示す出隅配置では、隣接するカーテンウォール18同士のコーナー部は、斜め方向に延びたコーナー方立60で連結されている。コーナー方立60は、室内側の端面に略三角形の断面形状を有するコーナー材61を有する。互いに隣接して出隅部を形成する開口部装置10,10は、それぞれコーナー材61の第1見込み面61aと第2見込み面61bとに取り付けられる。第1見込み面61a側の開口部装置10は、縦枠12cの外側見込み面20aが第1見込み面61aに突き当てられ、ねじ27でコーナー材61に締結される。第2見込み面61b側の開口部装置10は、縦枠12dの外側見込み面20aが第2見込み面61bに突き当てられ、ねじ27でコーナー材61に締結される。 In the external corner arrangement shown in FIG. 12, the corners of adjacent curtain walls 18 are connected by corner mullions 60 extending obliquely. The corner mullion 60 has a corner member 61 having a substantially triangular cross-sectional shape on the end face on the room side. The opening devices 10, 10 forming external corners adjacent to each other are attached to the first projection surface 61a and the second projection surface 61b of the corner member 61, respectively. The opening device 10 on the side of the first projection surface 61a is fastened to the corner member 61 with the screw 27 while the outer projection surface 20a of the vertical frame 12c abuts against the first projection surface 61a. The opening device 10 on the side of the second projection surface 61b is fastened to the corner member 61 with the screw 27 while the outer projection surface 20a of the vertical frame 12d abuts against the second projection surface 61b.

この出隅配置では、各開口部装置10が各カーテンウォール18間を連結するコーナー方立60よりも枠内側にある露出配置となっており、室内側に大きく張り出すことがない。このため、開口部装置10が、建物42の内観を損なうことを抑制できる。このような出隅配置において、各縦枠12c,12dと各見込み面61a,61bとの間は、第1気密材23が各見込み面61a,61bに密着することで室内外に気密される。 In this external corner arrangement, each opening device 10 is exposed inside the frame relative to the corner mullion 60 connecting the curtain walls 18, and does not protrude into the room. Therefore, it is possible to prevent the opening device 10 from impairing the interior appearance of the building 42 . In such an external corner arrangement, the space between the vertical frames 12c, 12d and the prospective surfaces 61a, 61b is airtight to the inside and outside of the room by the first airtightness member 23 coming into close contact with the prospective surfaces 61a, 61b.

図12中の参照符号62は、コーナー部で隣り合う開口部装置10同士の縦縁材16c,16dをまとめて覆うカバー部材である。参照符号63は、コーナー部で隣り合う各開口部装置10の室外側見付け片21の先端に設けられた第3気密材である。第3気密材63は、第2気密材29における室外側気密部29aの機能を持たず、室内側気密部29bと同様に機能する。 Reference numeral 62 in FIG. 12 denotes a cover member that collectively covers the vertical edge members 16c and 16d of the opening devices 10 adjacent to each other at the corner. A reference numeral 63 is a third airtight member provided at the tip of the outdoor side facing piece 21 of each opening device 10 adjacent at the corner. The third airtight member 63 does not have the function of the outdoor airtight portion 29a of the second airtight member 29, and functions similarly to the indoor airtight portion 29b.

図13に示す入隅配置は、図12に示す出隅配置と略同様な構造のコーナー方立60及びコーナー材61を有する。互いに隣接して入隅部を形成する開口部装置10,10は、それぞれコーナー材61の第1見込み面61aと第2見込み面61bとに取り付けられる。第1見込み面61a側の開口部装置10は、縦枠12cの室外側見付け片21が第1見込み面61aに当てられ、ねじ27でコーナー材61に締結される。第2見込み面61b側の開口部装置10は、縦枠12dの室外側見付け片21が第2見込み面61bに当てられ、ねじ27でコーナー材61に締結される。また、コーナー材61の室内側には、略六角形の断面形状を有するポスト材64が固定されている。各縦枠12c,12dの外側見込み面20aは、それぞれポスト材64の見込み面に突き当てられている。 The internal corner arrangement shown in FIG. 13 has corner mullions 60 and corner members 61 having substantially the same structure as the external corner arrangement shown in FIG. The opening devices 10, 10 forming the internal corners adjacent to each other are attached to the first projection surface 61a and the second projection surface 61b of the corner member 61, respectively. The opening device 10 on the side of the first projection surface 61 a is fastened to the corner member 61 with screws 27 while the outdoor side facing piece 21 of the vertical frame 12 c is brought into contact with the first projection surface 61 a. The opening device 10 on the side of the second projection surface 61b is fastened to the corner member 61 with the screw 27 while the exterior side edge piece 21 of the vertical frame 12d is brought into contact with the second projection surface 61b. A post member 64 having a substantially hexagonal cross-sectional shape is fixed to the interior side of the corner member 61 . The outer projected surfaces 20a of the vertical frames 12c and 12d are abutted against the projected surfaces of the post members 64, respectively.

この入隅配置では、各開口部装置10が各カーテンウォール18間を連結するコーナー方立60で隠された隠蔽配置となっている。これにより、開口部装置10は、枠体12や框体30がカーテンウォール18の面材18a,18b越しに建物42の外部から視認されることが抑制され、建物42の外観品質が向上する。また、開口部装置10は、枠体12や框体30がカーテンウォール18で隠されることで、出隅配置よりも面材31の開口面積が拡大する。このような入隅配置において、各縦枠12c,12dと各見込み面61a,61bとの間は、第1気密材23がポスト材64の見込み面に密着に密着している。さらに、各縦枠12c,12dの第2気密材29の室外側気密部29aが各見込み面61a,61bに密着している。これにより、各開口部装置10は、室内外に気密されている。図13中の参照符号66は、コーナー部で隣り合う開口部装置10同士の縦縁材16c,16d及びポスト材64をまとめて覆うカバー部材である。 In this internal corner arrangement, each opening device 10 is hidden by a corner mullion 60 connecting each curtain wall 18 . As a result, the opening device 10 prevents the frame 12 and the frame 30 from being seen from the outside of the building 42 through the face members 18a and 18b of the curtain wall 18, thereby improving the appearance quality of the building 42. In addition, in the opening device 10, the frame 12 and the frame 30 are hidden by the curtain wall 18, so that the opening area of the face member 31 is enlarged compared to the external corner arrangement. In such an internal corner arrangement, the first airtight member 23 is in close contact with the projection surfaces of the post members 64 between the vertical frames 12c and 12d and the projection surfaces 61a and 61b. Further, the outdoor-side airtight portions 29a of the second airtight members 29 of the vertical frames 12c, 12d are in close contact with the projected surfaces 61a, 61b. Thereby, each opening device 10 is airtight inside and outside the room. Reference numeral 66 in FIG. 13 denotes a cover member that collectively covers the vertical edge members 16c and 16d and the post members 64 of the opening devices 10 adjacent to each other at the corner.

ところで、例えば上記した露出配置の場合、枠体12は、上枠12a、下枠12b、及び第1露出配置の縦枠12c,12dでは、第2気密材29の室外側気密部29aが気密ラインとなる(図10A、図10B及び図10C参照)。一方、第2露出配置の縦枠12c,12dは、第1気密材23が気密ラインとなる(図10D参照)。そして、隠蔽配置の各枠12a~12dも略同様となっている(図11A~図11B参照)。ところが、枠体12の気密ラインは、第1気密材23と第2気密材29とが見込み方向に位置ずれしており、途中に非連続部を生じる。そこで、図14に示すように、第1気密材23と第2気密材29の室外側気密部29aとの間を補助気密材68で接続し、気密ラインを四周で連続させることが好ましい。補助気密材68は、例えばスポンジやゴム等で形成される。 By the way, for example, in the case of the exposed arrangement described above, the frame body 12 includes the upper frame 12a, the lower frame 12b, and the vertical frames 12c and 12d of the first exposed arrangement. (See FIGS. 10A, 10B and 10C). On the other hand, in the vertical frames 12c and 12d in the second exposed arrangement, the first airtight member 23 serves as an airtight line (see FIG. 10D). The frames 12a to 12d in the hidden arrangement are also substantially the same (see FIGS. 11A to 11B). However, in the airtight line of the frame 12, the positions of the first airtight member 23 and the second airtight member 29 are shifted in the projection direction, and a discontinuous portion is generated in the middle. Therefore, as shown in FIG. 14, it is preferable to connect the first airtight member 23 and the outdoor airtight portion 29a of the second airtight member 29 with an auxiliary airtight member 68 so that the airtight line is continuous on all four sides. The auxiliary airtight material 68 is made of, for example, sponge or rubber.

なお、全ての枠12a~12dが露出配置の場合には、全ての枠12a~12dについて、例えば第1気密材ポケット22を利用し、全て第1気密材23で統一し、これにより、気密ラインを四周で連続させてもよい。同様に、全ての枠12a~12dが隠蔽配置の場合には、全ての枠12a~12dについて、例えば第2気密材ポケット28を利用し、全て第2気密材29の室外側気密部29aで統一し、これにより、気密ラインを四周で連続させてもよい。 In addition, when all the frames 12a to 12d are exposed, for example, the first airtight material pocket 22 is used for all the frames 12a to 12d, and the first airtight material 23 is used for all the frames 12a to 12d. may be continuous in four circles. Similarly, when all the frames 12a to 12d are arranged to be concealed, for example, the second airtight material pocket 28 is used for all the frames 12a to 12d, and the outdoor airtight part 29a of the second airtight material 29 is unified. However, this may allow the airtight line to be continuous on all four sides.

例えば図15に示すように、1つの開口部装置10で露出配置と隠蔽配置が併用されてもよい。図15は、上枠12a及び下枠12bを図10A及び図10Bと同様な露出配置とし、縦枠12c,12dを図11C及び図11Dと同様な隠蔽配置とした構成を例示している。この構成では、露出配置の枠12a,12bと外窓枠43との間の気密ラインを形成する第2気密材29の室外側気密部29aと、隠蔽配置の枠12c,12dと外窓枠43や方立48との間の気密ラインを形成する第1気密材23との間が、見込み方向に位置ずれする。そこで、この部分に補助気密材68を設け、気密ラインを四周で連続させている。 For example, as shown in FIG. 15, a single aperture device 10 may be used in both exposed and concealed configurations. FIG. 15 illustrates a configuration in which the upper frame 12a and the lower frame 12b are exposed as in FIGS. 10A and 10B, and the vertical frames 12c and 12d are concealed as in FIGS. 11C and 11D. In this configuration, the outdoor airtight portion 29a of the second airtight member 29 forming an airtight line between the frames 12a and 12b in the exposed arrangement and the outer window frame 43, the frames 12c and 12d in the concealed arrangement and the outer window frame 43 The first airtight member 23 forming an airtight line with the mullion 48 is displaced in the expected direction. Therefore, an auxiliary airtight material 68 is provided at this portion to make the airtight line continuous on all four sides.

以上のように、本実施形態の開口部装置10において、縦枠12c,12dは、外側見込み面20aに第1取付部25aを有し、室外側見付け面(室外側見付け片21)に第2取付部25bを有する。これにより枠体12は、建物42の躯体部材への取付時、少なくとも取付部25a,25bの一方を使用した柔軟な取り付けが可能となる。つまり開口部装置10は、上記した露出配置と隠蔽配置とで枠体12を兼用できる。その結果、開口部装置10は、高い汎用性が得られ、異なる設置状態に対応可能でありながらも製造コストを低減できる。なお、第2取付部25bは、上枠12a及び下枠12bにも設け、上枠12a及び下枠12bの設置状態をより柔軟に構成することもできる。 As described above, in the opening device 10 of the present embodiment, the vertical frames 12c and 12d have the first mounting portion 25a on the outer projection surface 20a, and the second mounting portion 25a on the outdoor side facing surface (outdoor facing piece 21). It has a mounting portion 25b. As a result, the frame 12 can be flexibly attached using at least one of the attachment portions 25a and 25b when attached to the frame member of the building 42. As shown in FIG. That is, the opening device 10 can use the frame 12 in both the exposed arrangement and the concealed arrangement. As a result, the opening device 10 can achieve high versatility and reduce manufacturing costs while being adaptable to different installation conditions. The second mounting portion 25b can also be provided on the upper frame 12a and the lower frame 12b, so that the installation state of the upper frame 12a and the lower frame 12b can be configured more flexibly.

また、本実施形態の開口部装置10において、各枠12a~12dは、外側見込み面20aに第1気密材ポケット22を有し、室外側見付け面(室外側見付け片21)に第2気密材ポケット28を有する。これにより枠体12は、建物42の躯体部材への取付時、少なくとも気密材ポケット22,28の一方に気密材23,29を装着した柔軟な気密ラインの構築が可能となる。つまり開口部装置10は、気密性能の面でも上記した露出配置と隠蔽配置とで枠体12を兼用できる。 In addition, in the opening device 10 of this embodiment, each of the frames 12a to 12d has the first airtight material pocket 22 on the outer prospective surface 20a, and the second airtight material pocket 22 on the outdoor side facing surface (outdoor side facing piece 21). It has a pocket 28 . As a result, when the frame 12 is attached to the frame member of the building 42, it is possible to construct a flexible airtight line in which the airtight materials 23, 29 are attached to at least one of the airtight material pockets 22, 28. - 特許庁In other words, the opening device 10 can use the frame 12 in both the exposed arrangement and the concealed arrangement in terms of airtightness.

図16Aに示すように、上枠12aの周辺部では、下地材46の躯体42a側のモルタル72が充填された空間に防火設備連結材70が設置されている。防火設備連結材70は、躯体42aと開口部装置10との間を直接的に連結する防火用の金属部材である。上枠12aは、ねじ27を介して防火設備連結材70と連結されている。図16A中の参照符号74は、下地材46の内側空間を塞ぐ難燃性の塞ぎ材である。 As shown in FIG. 16A, in the peripheral portion of the upper frame 12a, a fire prevention equipment connecting member 70 is installed in a space filled with mortar 72 on the frame 42a side of the base member 46. As shown in FIG. The fire prevention equipment connection member 70 is a metal member for fire prevention that directly connects between the frame 42 a and the opening device 10 . The upper frame 12 a is connected to the fire prevention equipment connecting member 70 via the screw 27 . Reference numeral 74 in FIG. 16A denotes a flame-retardant plugging member that plugs the inner space of the base member 46 .

図16Bに示すように、下枠12bの周辺部では、下地材46の躯体42a側のモルタル72が充填された空間に防火設備連結材70が設置されている。防火設備連結材70は、ねじ27を介して下枠12bと連結されている。 As shown in FIG. 16B, in the peripheral portion of the lower frame 12b, a fire prevention equipment connecting member 70 is installed in a space filled with mortar 72 on the frame 42a side of the base member 46. As shown in FIG. The fire prevention equipment connection member 70 is connected to the lower frame 12b via the screw 27. As shown in FIG.

図16Cに示すように、縦枠12c,12dの周辺部では、カーテンウォール18,18同士を連結した方立48の室内側に別途設置された防火設備連結材76を介して、左右に並んだ開口部装置10,10同士が連結されている。防火設備連結材76は、左右の開口部装置10の縦枠12c,12dとそれぞれ連結される方立部76aを有する。方立部76aの一方の見込み面には、一方の開口部装置10の縦枠12dの外側見込み面20aが突き当てられ、ねじ27で固定されると共に、第1気密材23で気密されている。方立部76aの他方の見込み面には、他方の開口部装置10の縦枠12cの外側見込み面20aが突き当てられ、ねじ27で固定されると共に、第1気密材23で気密されている。防火設備連結材76の周囲は、コ字状の断面形状を有するカバー部材78で覆われ、外観品質が確保されている。 As shown in FIG. 16C, in the peripheral part of the vertical frames 12c, 12d, the curtain walls 18, 18 are arranged side by side via a fire prevention equipment connection member 76 separately installed on the indoor side of the mullion 48 that connects the curtain walls 18, 18 together.

As shown in FIG. The periphery of the fire prevention equipment connecting member 76 is covered with a cover member 78 having a U-shaped cross section to ensure the appearance quality.

<4.開口部装置の施工方法の説明>
次に、開口部装置10の施工方法の一手順を説明する。以下では、カーテンウォール18を構成する左右の縦材が共に方立48である場合に、左右の方立48,48間に開口部装置10の枠体12を取り付ける方法を代表的に説明する。但し、以下の施工方法は、カーテンウォール18を構成する左右の縦材のうち、一方が方立48であればよく、他方は図10C等に示す縦枠部43c,43dで構成されてもよい。
<4. Explanation of Construction Method of Opening Device>
Next, one procedure of the construction method of the opening device 10 will be described. A method of attaching the frame 12 of the opening device 10 between the left and right mullions 48, 48 when the left and right vertical members constituting the curtain wall 18 are both mullions 48 will be described below as a representative example. However, in the following construction method, one of the left and right vertical members forming the curtain wall 18 may be the mullion 48, and the other may be formed by the vertical frame portions 43c and 43d shown in FIG. 10C and the like. .

図17Aに示すように、左右の方立48は、その上下端部がいずれもファスナー44に対して左右にスライド可能に支持された仮固定状態としておく。この状態で、先ず、一方の方立48(図17A中で左側の方立48)を上下のファスナー44と固定し、この方立48の左右方向位置を位置決めする(位置決め工程)。 As shown in FIG. 17A, the left and right mullions 48 are in a temporarily fixed state in which both upper and lower ends thereof are supported so as to be slidable to the left and right relative to the fasteners 44 . In this state, first, one mullion 48 (the left mullion 48 in FIG. 17A) is fixed to the upper and lower fasteners 44, and the horizontal position of this mullion 48 is positioned (positioning step).

当該施工方法では、枠体12は、予め工場或いは施工現場にて四周が枠組みされている。具体的には、枠体12は、図18に示すように、上枠12aと左右の縦枠12c,12dがねじ80を用いて固定され、下枠12bと左右の縦枠12c,12dもねじ80を用いて固定されている。なお、図18では、上枠12aと縦枠12cとの連結部のみを図示しているが、他の連結部も同様な連結構造でよい。 In the construction method, the frame body 12 is framed on all four sides in advance at the factory or at the construction site. Specifically, as shown in FIG. 18, the frame 12 has an upper frame 12a and left and right vertical frames 12c and 12d fixed with screws 80, and a lower frame 12b and left and right vertical frames 12c and 12d are also screwed. 80 is used. Although FIG. 18 shows only the connecting portion between the upper frame 12a and the vertical frame 12c, other connecting portions may have the same connecting structure.

そこで、上記位置決め工程の後、予め枠組みされた枠体12を方立48,48間に配置し、一方の縦枠12cを位置決め工程で位置決めした方立48に当接させる。この際、上記した露出配置では、枠体12は、縦枠12cの外側見込み面20aを方立48の内側見込み面48aに当接させる(図10D参照。第1当接工程)。一方、上記した隠蔽配置では、枠体12は、縦枠12cの室外側見付け片21を方立48の室内側見付け面48bに当接させる(図11D参照。第1当接工程)。続いて、これら縦枠12cと方立48とをねじ27で固定する(第1固定工程)。なお、この第1固定工程は、下記の第2当接工程の後、第2固定工程と同時に又はその前後に行ってもよい。 Therefore, after the positioning process, the frame body 12 that has been framed in advance is arranged between the mullions 48, 48, and one vertical frame 12c is brought into contact with the mullion 48 positioned in the positioning process. At this time, in the exposed arrangement described above, the frame body 12 brings the outer prospective surface 20a of the vertical frame 12c into contact with the inner prospective surface 48a of the mullion 48 (see FIG. 10D, first contact step). On the other hand, in the concealed arrangement described above, the frame body 12 brings the outdoor-side facing piece 21 of the vertical frame 12c into contact with the indoor-side facing surface 48b of the mullion 48 (see FIG. 11D, first contact step). Subsequently, the vertical frame 12c and the mullion 48 are fixed with screws 27 (first fixing step). The first fixing step may be performed after the second contacting step described below, at the same time as or before or after the second fixing step.

なお、図10Cや図11Cに示すように、例えば枠体12の縦枠12cを、カーテンウォール18の縦枠部43cに固定する構成の場合は、上記位置決め工程は、縦枠部43cの躯体42a側への取付工程となり、上記第1当接工程及び第1固定工程は、縦枠部43cへの縦枠12cの当接工程及び固定工程となる。 As shown in FIGS. 10C and 11C, for example, in the case of a configuration in which the vertical frame 12c of the frame 12 is fixed to the vertical frame portion 43c of the curtain wall 18, the positioning step is performed by The first contacting step and the first fixing step correspond to the contacting step and fixing step of the vertical frame 12c to the vertical frame portion 43c.

次いで、第1当接工程で左右位置が位置決めされた枠体12に向かって、他方の方立48(図17A中で右側の方立48)をスライドさせ、他方の縦枠12dに当接させる。この際、上記した露出配置では、方立48は、縦枠12dの外側見込み面20aに内側見込み面48aを当接させる(図10D参照。第2当接工程)。一方、上記した隠蔽配置では、方立48は、縦枠12dの室外側見付け片21に室内側見付け面48bを当接させる(図11D参照。第2当接工程)。続いて、これら縦枠12dと方立48とをねじ27で固定する(第2固定工程)。 Next, the other mullion 48 (the right mullion 48 in FIG. 17A) is slid toward the frame 12 whose left and right positions have been positioned in the first contact step, and is brought into contact with the other vertical frame 12d. . At this time, in the exposed arrangement described above, the mullion 48 brings the inner prospective surface 48a into contact with the outer prospective surface 20a of the vertical frame 12d (see FIG. 10D, second contact step). On the other hand, in the concealed arrangement described above, the mullion 48 brings the indoor side facing surface 48b into contact with the outdoor side facing piece 21 of the vertical frame 12d (see FIG. 11D, second contacting step). Subsequently, the vertical frame 12d and the mullion 48 are fixed with screws 27 (second fixing step).

なお、開口部装置10を施工する上記各工程では、カーテンウォール18の面材18a,18bの施工も同時に行う。つまり、上記した第1当接工程及び第2当接工程時、方立48,48間に面材18a,18bを配置しておく。これにより、当該施工方法は、開口部装置10と共にカーテンウォール18の施工も同時に行うことができる。 In addition, in each of the steps for constructing the opening device 10, the surface members 18a and 18b of the curtain wall 18 are also constructed at the same time. That is, the face members 18a and 18b are arranged between the mullions 48 and 48 during the first contact step and the second contact step. Thus, the construction method can simultaneously construct the opening device 10 and the curtain wall 18 .

次いで、カーテンウォール18の上枠部43aと枠体12の上枠12aとの間に、上膳板となる額縁部材50を差し込み、上枠12aを下地材46や上枠部43aにねじ27で固定する(図10A及び図11A参照。上膳板設置工程)。さらに、この上膳板設置工程と同時に又は前後して、カーテンウォール18の下枠部43bと枠体12の下枠12bとの間に、下膳板となる額縁部材50を差し込み、下枠12bを下地材46や下枠部43bとねじ27で固定する(図10B参照。下膳板設置工程)。なお、図11Bに示す露出配置では、下枠部43bと下枠12bとの間に下膳板となる額縁部材50を設けていないため、下膳板設置工程では、下枠12b及び額縁部材50を下地材46や下枠部43bとねじ27で固定することになる。 Next, between the upper frame portion 43a of the curtain wall 18 and the upper frame portion 12a of the frame body 12, the frame member 50 serving as the upper plate is inserted, and the upper frame portion 12a is attached to the base material 46 and the upper frame portion 43a by screws 27. It is fixed (see FIGS. 10A and 11A. Upper tray installation step). Furthermore, at the same time as or before or after this step of installing the upper tray, the frame member 50 serving as the lower tray is inserted between the lower frame portion 43b of the curtain wall 18 and the lower frame 12b of the frame body 12, and the lower frame 12b is inserted. is fixed to the backing material 46 and the lower frame portion 43b with the screws 27 (see FIG. 10B. lower tray installation step). In the exposed arrangement shown in FIG. 11B, since the frame member 50 serving as the lower plate is not provided between the lower frame portion 43b and the lower frame 12b, the lower frame 12b and the frame member 50 are not provided in the lower plate installation step. are fixed to the backing material 46 and the lower frame portion 43b by the screws 27. As shown in FIG.

以上より、開口部装置10は、枠体12が躯体42aや躯体部材となる方立48等と固定される。そこで、必要に応じて蝶番部品34等を装着し、障子14を建て込んでから押縁16を取り付けることで、開口部装置10の施工が完了する。 As described above, in the opening device 10, the frame 12 is fixed to the frame 42a or the mullion 48 that serves as a frame member. Therefore, the construction of the opening device 10 is completed by attaching the hinge parts 34 and the like as necessary, erecting the shoji 14, and then attaching the rim 16. - 特許庁
