Description

本発明は、複層ガラスの周端部が框材に収容された障子および建具に関する。 [Technical Field] The present invention relates to a shoji and joinery in which a peripheral end portion of a multilayer glass is accommodated in a saddle member.

複層ガラスの周端部が框材に収容された障子および建具としては、例えば、樹脂枠体内に、合成樹脂製の下框、上框および縦框を框組みした框体に複層ガラス（ガラス体）を納めてなる内障子および外障子を引違い状で走行自在となるように納めた樹脂サッシが知られている（例えば、特許文献１参照）。下框、上框及び縦框はいずれも断面形状が略同形状になるように形成されており、それぞれ傾斜状に形成された下框、上框、縦框の各端部同士が突き合わされて溶着にて連結されて框体をなしている。 Examples of the shoji and fittings in which the peripheral edge of the multi-layer glass is housed in a frame include, for example, a multi-layer glass ( There is known a resin sash in which inner and outer shojis containing a glass body are housed so as to be able to run in a dragged manner (see, for example, Patent Document 1). The lower heel, upper heel, and vertical hook are all formed so that their cross-sectional shapes are substantially the same, and the ends of the lower heel, upper heel, and vertical heel formed in an inclined shape are abutted with each other. Connected by welding to form a housing.

このような障子および建具は、枠体が形成する開口を閉塞するように内障子および外障子を閉じると、各障子の下框、上框と戸先側の縦框は、枠体に沿って係合しているため変形し難いが、各々の召合せ部となる縦框は、上下の端部のみが枠体と係合しているだけなので、変形しやすい。このため、上記障子の召合せ部となる縦框には、互いに対向する部位にそれぞれアルミニウムなどの金属製の煙返し部材がそれぞれ固定されている。 When such shojis and fittings close the inner and outer shojis so as to close the opening formed by the frame, the lower arm, upper arm and the vertical spatula of each shoji are along the frame. Although it is difficult to deform because it is engaged, the vertical hooks that are the respective summing parts are easily deformed because only the upper and lower ends are engaged with the frame. For this reason, metal smoke return members, such as aluminum, are being fixed to the mutually facing parts, respectively, in the vertical fence that is the summoning part of the shoji.

特許第４０２７９２０号公報Japanese Patent No. 4027920

互いに連結されて框体をなす下框、上框および縦框等の框材の材質が互いに相違しており、各框材の端部同士を溶着にて強固に連結できない場合には、各框の端部同士をねじ固定にて連結する方法がある。このとき、例えば、真夏の日照等により加熱されて各框材が伸長した際に、各々の連結部に応力が作用し、框材が変形または破損するおそれがあるという課題がある。 When the materials of the brazing material such as the lower brace, the upper gutter and the vertical gutter which are connected to each other are different from each other, and the ends of each brazing material cannot be firmly connected by welding, There is a method of connecting the end portions of each other with screws. At this time, for example, when each brazing material is heated by midsummer sunlight or the like, stress is applied to each connecting portion, and there is a problem that the brazing material may be deformed or broken.

本発明は、かかる課題に鑑みてなされたものであり、その目的とするところは、互いに材質が異なる框材を備えていても加熱または冷却による歪みが生じ難い障子及びこの障子を備えた建具を提供することにある。 The present invention has been made in view of such problems, and an object of the present invention is to provide a shoji that is difficult to be distorted by heating or cooling, even if it is provided with different materials from each other, and a fitting provided with this shoji. It is to provide.

かかる目的を達成するために本発明の障子は、対面する２枚の板ガラスがその周縁部に不燃性または難燃性の骨材を介して接合された複層ガラスと、前記複層ガラスの周端部を収容し、互いに材質が異なる複数種類の框材と、を有し、前記複層ガラスの上下左右に配置される４本の前記框材は、前記骨材に各々固定されていることを特徴とする障子である。

In order to achieve such an object, the shoji of the present invention comprises a double-layer glass in which two facing glass plates are bonded to the peripheral edge thereof via an incombustible or flame-retardant aggregate, and a periphery of the multi-layer glass. housing the end portion, anda plurality of rail members having different materials from each other, four said rail members that are arranged vertically and horizontally of the double glazing, it being respectively fixed to the aggregate It is a shoji characterized by.

このような障子によれば、複層ガラスの周端部を収容し互いに材質が異なる複数種類の框材は、複層ガラスの２枚の板ガラスの周縁部に設けられて２枚の板ガラスを接合する不燃性または難燃性の骨材に各々固定されているので、框材同士を接合する必要はない。このため、たとえ複層ガラスの周端部を収容し材質が互いに異なる複数種類の框材が加熱または冷却されたとしても、各框材が複層ガラスの骨材に固定されて互いに連結されていないので、各々の伸縮を、隣り合う框材が規制しないため歪みが生じ難い障子を提供することが可能である。 According to such a shoji, a plurality of types of saddles that accommodate the peripheral edge of the multi-layer glass and are made of different materials are provided on the peripheral edge of the two glass plates of the multi-layer glass and join the two glass plates. Since it is fixed to the non-combustible or flame-retardant aggregate, it is not necessary to join the brazing materials. For this reason, even if a plurality of types of brazing materials that contain the peripheral edge of the multilayer glass and are different from each other are heated or cooled, the brazing materials are fixed to the aggregate of the multilayer glass and connected to each other. Therefore, it is possible to provide a shoji that is less likely to be distorted because each adjacent expansion / contraction material is not restricted.

かかる障子と、構造体に固定されて前記障子により閉塞される開口を形成する枠体と、を備えた建具であって、前記複数種類の框材のうち前記障子が前記開口を閉塞した際に、前記枠体に沿って係合しない非係合框材は、前記枠体に沿って係合する係合框材と前記材質が異なることが望ましい。 A joinery comprising such a shoji and a frame that is fixed to a structure and forms an opening that is blocked by the shoji, and when the shoji closes the opening of the plurality of types of saddles The non-engaging saddle that does not engage along the frame is preferably different in material from the engaging saddle that engages along the frame.

このような建具によれば、構造体に固定された枠体に沿って係合する係合框材は障子を閉じた際には変形しにくい。一方枠体に沿って係合しない非係合框材は、障子を閉じた状態であっても変形しやすい。このため、非係合框材を係合框材より変形しにくい材質にて形成することにより、障子の変形を効率よく抑えることが可能である。 According to such a joinery, the engagement saddle that engages along the frame fixed to the structure is not easily deformed when the shoji is closed. On the other hand, the non-engaging saddle that does not engage along the frame body is easily deformed even when the shoji is closed. For this reason, it is possible to efficiently suppress the deformation of the shoji by forming the non-engaging saddle member from a material that is more difficult to deform than the engaging saddle member.

かかる建具であって、前記非係合框材の前記材質は金属であり、前記係合框材の前記材質は合成樹脂であることが望ましい。
このような建具によれば、非係合框材は金属製なので、火炎などに晒されたとしても変形を抑えることが可能であり、係合框材は合成樹脂製なので、全ての框材がたとえば金属などにて形成された建具より、断熱性が高い建具を提供することが可能である。 In this fitting, it is preferable that the material of the non-engaging saddle member is a metal, and the material of the engaging saddle member is a synthetic resin.
According to such a joinery, since the non-engaging brazing material is made of metal, it is possible to suppress deformation even when exposed to a flame or the like, and since the engaging brazing material is made of synthetic resin, For example, it is possible to provide a joinery having higher heat insulation than a joinery formed of metal or the like.

かかる建具であって、前記非係合框材は、召合せ框であることが望ましい。
召合せ框は、室内外の境界部分に位置するので、召合せ框を金属製の部材にすることにより変形しにくくなり、密閉性に優れた建具を提供することが可能である。 In such a joinery, it is preferable that the non-engaging saddle member is a summon barb.
Since the summon basket is located at the boundary between the inside and outside of the room, it becomes difficult to be deformed by making the summon basket into a metal member, and it is possible to provide a fitting with excellent sealing performance.

かかる建具であって、前記非係合框材は、突合せ框であることとしてもよい。
このような建具によれば、引分け戸や４枚建などの引戸の障子が備える突合せ框は室内外の境界部に位置するので、引分け戸や４枚建などの引戸においても、より密閉性を向上させることが可能である。 In such a joinery, the non-engaging saddle member may be a butt tack.
According to such a joinery, the butt rods provided in the sliding doors such as the sliding door and the four-story door are located at the boundary between the indoor and the outdoor. It is possible to improve the property.

本発明によれば、材質が互いに異なる框材を備えていても加熱または冷却による歪みが生じ難い障子及びこの障子を備えた建具を提供することが可能である。 According to the present invention, it is possible to provide a shoji that does not easily cause distortion due to heating or cooling, and a joinery equipped with this shoji, even if different materials are provided.

Have.

召合せ框２３は、戸先側に向かって開放されて複層ガラス１７の召合せ側の端部を収容するガラス収容溝２３ａを有し、ガラス収容溝２３ａと反対側には、平板状のカバー材２４により閉塞されて上下方向に貫通する中空部２３ｂが備えられている。 The summoning bowl 23 has a glass accommodating groove 23a that is opened toward the door end side and accommodates the end portion on the summing side of the multi-layer glass 17, and on the opposite side of the glass accommodating groove 23a, a flat plate-like shape is provided. A hollow portion 23b that is closed by the cover member 24 and penetrates in the vertical direction is provided.

上框２０、下框２１、戸先框２２および召合せ框２３は、上框２０、下框２１、戸先框２２が有するレール収容溝２０ｂ、２１ｂまたは突出部収容溝２２ｂおよび召合せ框２３が有する中空部２３ｂに設けられた不燃性であるステンレス製の補強部材２５とともに、複層ガラス１７の骨材１６に固定されている。補強部材２５は、断面コ字状をなして各框材２０、２１、２２、２３の長手方向に沿ってほぼ全域に渡って設けられており、各框材２０、２１、２２、２３が複層ガラス１７に取り付けられた状態で障子３の外周側に、コ字状の補強部材２５において開放された側が向くように取り付けられる。 The upper rod 20, the lower rod 21, the door rod 22 and the summit rod 23 are the rail accommodating grooves 20b and 21b or the protrusion accommodating grooves 22b and the summon rod 23 which the upper rod 20, the lower rod 21, and the door rod 22 have. Together with a non-combustible stainless steel reinforcing member 25 provided in the hollow portion 23b of the multi-layer glass 17. The reinforcing member 25 has a U-shaped cross section and is provided over almost the entire area along the longitudinal direction of each brazing member 20, 21, 22, 23. In the state attached to the layer glass 17, it attaches to the outer peripheral side of the shoji 3 so that the open side in the U-shaped reinforcement member 25 may face.

上框２０、下框２１および戸先框２２は、枠体１０にて形成される開口１０ａが障子３により閉塞されると、上框２０及び下框２１のレール収容溝２０ｂ、２１ｂに上レール１２ａまたは下レール１１ａが収容され、戸先框２２の突出部収容溝２２ｂに突出部１３ａが収容されることにより、枠体１０に沿って係合する。すなわち、上框２０、下框２１および戸先框２２が枠体１０に沿って係合する係合框材に相当する。係合框材である上框２０、下框２１および戸先框２２は、開口１０ａを障子３が閉塞している状態で、躯体２に固定された枠体１０と、その長手方向のほぼ全域にて係合しているので、複層ガラス１７における面外方向に変形し難い。 When the opening 10 a formed in the frame 10 is closed by the shoji 3, the upper rod 20, the lower rod 21, and the door rod 22 are connected to the rail receiving grooves 20 b and 21 b of the upper rod 20 and the lower rod 21. 12a or the lower rail 11a is accommodated, and the projecting portion 13a is accommodated in the projecting portion accommodating groove 22b of the door rod 22 to be engaged along the frame body 10. That is, it corresponds to an engagement rod material in which the upper rod 20, the lower rod 21 and the door rod 22 are engaged along the frame body 10. The upper rod 20, the lower rod 21 and the door rod 22 which are the engagement rods are the frame 10 fixed to the frame 2 in a state where the shoji 3 is closed in the opening 10a, and almost the entire area in the longitudinal direction thereof. , The multi-layer glass 17 is hardly deformed in the out-of-plane direction.

召合せ框２３は、枠体１０にて形成される開口１０ａが障子３により閉塞された際に、上端部及び下端部のみが上枠１２または下枠１１と係合する。すなわち、召合せ框２３が枠体１０に沿って係合しない非係合框材に相当する。このため、非係合框材である召合せ框２３は、開口１０ａを障子３が閉塞している状態であっても、上框２０、下框２１および戸先框２２よりも、複層ガラス１７における面外方向に変形し易い。このため、召合せ框２３およびカバー材２４は、上框２０、下框２１および戸先框２２と異なりアルミニウム製の押出成形部材で構成されている。 When the opening 10 a formed in the frame body 10 is closed by the shoji 3, only the upper end and the lower end of the summoning cage 23 engage with the upper frame 12 or the lower frame 11. In other words, the summon bar 23 corresponds to a non-engagement bar that does not engage along the frame 10. For this reason, the summoning scissors 23 which are non-engaging scissors have a multi-layer glass rather than the upper scissors 20, the lower scissors 21 and the door end scissors 22 even when the shoji 3 is closing the opening 10a. 17 easily deforms in the out-of-plane direction. For this reason, the summoning bowl 23 and the cover material 24 are made of an extruded member made of aluminum, unlike the upper bowl 20, the lower bowl 21 and the door-end fence 22.

内障子３と外障子３とにおいて、上框２０同士、下框２１同士および戸先框２２同士はそれぞれ同形状であるが、召合せ框２３については、図５に示すように、内障子３の召合せ框３３は、補強部材２５が設けられている中空部３３ｂの室内側に突出する室内側中空部３３ｊを有している。この室内側中空部３３ｊにより、室内側からの火炎に対する防火性が向上するとともに風荷重に対する剛性も高められている。また、召合せ框２３、３３は、内障子３及び外障子３を閉じたときに室内側から見える部位に、アルミニウムの表面を覆うように化粧カバー２３１、３３１が設けられている。内障子３の化粧カバー３３１には、外障子３のカバー材２４に対応する部位も一体に形成されている。 In the inner shoji 3 and the outer shoji 3, the upper kites 20, the lower kites 21 and the door-end kites 22 have the same shape. The summoning bowl 33 has an indoor-side hollow portion 33j that protrudes to the indoor side of the hollow portion 33b in which the reinforcing member 25 is provided. The indoor side hollow portion 33j improves the fire resistance against the flame from the indoor side and also increases the rigidity against the wind load. In addition, as for the summon baskets 23 and 33, decorative covers 231 and 331 are provided so as to cover the surface of the aluminum in a portion that can be seen from the indoor side when the inner and outer shojis 3 and 3 are closed.
