Description
本発明は、防火性を備えた建具に関する。 The present invention relates to a fitting having fire protection.
防火性を備えた建具は、火災時に防火性能を確保するために、枠と障子との間に加熱発泡材を備え、火災の熱により発泡した加熱発泡材により枠と障子との間に障子の全周に渡って連続した火炎に対するタイトラインが形成されることが望ましい。 Fittings with fire protection are equipped with a heated foam between the frame and the shoji to ensure fire protection in the event of a fire. It is desirable that a tight line for a continuous flame is formed over the entire circumference.
建具は、開口を形成する枠に開閉自在に障子が設けられる場合には、枠と障子との間に、取付部材として、例えばヒンジが設けられている場合がある。ヒンジは、障子のサイズが大きい場合には、障子を支持する為にヒンジ自体にも高い剛性が求められる。このため、枠と障子にそれぞれ固定される、ヒンジの部位は、リブなどを設けて剛性が高められている。 In the case of a fitting, when a frame forming an opening is provided with an openable / closable shoji, a hinge, for example, may be provided between the frame and the shoji as an attachment member. When the size of the hinge is large, the hinge itself is required to have high rigidity in order to support the hinge. For this reason, the portions of the hinge fixed to the frame and the shoji each have a rib or the like to increase rigidity.
上記建具のように、剛性が高いヒンジにより障子が枠に固定されている建具では、固定されているヒンジの表面に凹凸があるため、加熱発泡材等を貼り付けたとしても接着面積が十分に確保できず貼り付けられない、或いは、接着し難い虞があり、ヒンジが設けられている範囲においてタイトラインが連続して形成できず防火性が低下するという課題がある。
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、より防火性が高い建具を提供することにある。
As in the case of the above fittings, in fittings in which the shoji is fixed to the frame by a hinge having high rigidity, the surface of the fixed hinge has irregularities, so even if a heating foam material or the like is attached, the bonding area is sufficient. There is a possibility that it cannot be secured and cannot be stuck, or there is a possibility that adhesion is difficult, and there is a problem that a tight line cannot be continuously formed in a range where a hinge is provided, and fire resistance is reduced.
The present invention has been made in view of such a problem, and an object of the present invention is to provide a fitting having higher fire resistance.
かかる目的を達成するために本発明の建具は開口を形成する枠体と、前記開口に設けられる障子と、表面に複数の突部を有し、前記枠体と前記障子が対向する部位に取り付けられる取付部材と、前記取付部材が有する前記複数の突部を覆う平坦な面をなす平坦部を備えて、当該取付部材が取り付けられている前記枠体または前記障子に固定されるカバー部材と、前記平坦部に接着されている加熱発泡材と、を有することを特徴とする建具である。 In order to achieve such an object, the fitting of the present invention has a frame forming an opening, a shoji provided in the opening, and a plurality of protrusions on a surface, and is attached to a portion where the frame and the shoji face each other. A mounting member, comprising a flat portion that forms a flat surface covering the plurality of protrusions that the mounting member has, a cover member that is fixed to the frame or the sash to which the mounting member is mounted, And a heated foam material adhered to the flat portion.
このような建具によれば、表面に複数の突部を有している取付部材が、枠体と障子が対向する部位に取り付けられており、取付部材の表面を覆う平坦部を備えたカバー部材の平坦部に加熱発泡材が接着されている。このため、加熱発泡材は、複数の突部を有する取付部材の表面ではなく、取付部材の表面を覆うカバー部材の平坦部に接着されているので、十分な接着面積を確保して加熱発泡材を備えることが可能である。このため、枠体と障子とが対向する部位の表面に複数の突部を備えている取付部材が設けられていたとしても、加熱発泡材は外れ難く、より確実に配置しておくことが可能である。このため、枠体と障子とが対向する部位に連続した火炎に対するタイトラインが形成しやすいので、より防火性が高い建具を提供することが可能である。 According to such a fitting, a mounting member having a plurality of protrusions on the surface is mounted on a portion where the frame body and the shoji are opposed to each other, and a cover member having a flat portion covering the surface of the mounting member. The heated foam material is adhered to the flat part of. For this reason, the heating foam material is bonded not to the surface of the mounting member having a plurality of protrusions but to the flat portion of the cover member that covers the surface of the mounting member. Can be provided. For this reason, even if an attachment member having a plurality of protrusions is provided on the surface of the portion where the frame body and the shoji face each other, the heated foam material is unlikely to come off and can be more securely arranged. It is. For this reason, a tight line for a continuous flame is easily formed at a portion where the frame and the shoji face each other, so that it is possible to provide a fitting with higher fire resistance.
かかる建具であって、前記カバー部材は、前記平坦部から突出し、前記加熱発泡材が前記平坦部との間に配置される突出部を備えていることが望ましい。
このような建具によれば、加熱発泡材は、カバー部材の平坦部から突出する突出部と平坦部との間に配置されているので、加熱発泡材の剥がれる方向への移動が突出部により規制される。このため、加熱発泡材はより剥がれにくいので、より確実に平坦部に留めておくことが可能である。
In such fittings, it is preferable that the cover member includes a protruding portion that protrudes from the flat portion and the heated foam material is disposed between the flat member and the flat portion.
According to such a fitting, since the heating foam is disposed between the flat portion and the projection protruding from the flat portion of the cover member, the movement of the heating foam in the peeling direction is restricted by the projection. Is done. For this reason, since the heat-foamed material is harder to peel off, it is possible to more reliably keep the heat-foamed material on the flat portion.
かかる建具であって、前記枠体と前記障子との間には、前記カバー部材とともに全周に繋がるように、加熱発泡材が設けられていることが望ましい。
このような建具によれば、枠体と障子との間には、平坦部に加熱発泡材が設けられているカバー部材と、当該カバー部材とともに設けられる加熱発泡材とが全周に繋がっているので、ほぼ全周に渡って加熱発泡材が設けられている。枠体と障子とが対向する部位において、取付部材が設けられている部位の全域に加熱発泡材が設けられていない場合より、高い防火性を備えることが可能である。
In this fitting, it is preferable that a heating foam material is provided between the frame and the shoji so as to be connected to the entire circumference together with the cover member.
According to such a fitting, between the frame and the shoji, the cover member in which the heating foam is provided on the flat portion and the heating foam provided with the cover member are connected to the entire circumference. Therefore, the heating foam material is provided over almost the entire circumference. In a portion where the frame and the shoji face each other, it is possible to provide higher fire protection than a case where the heating foam material is not provided over the entire region where the attachment member is provided.
かかる建具であって、前記取付部材は、前記障子を前記枠体に開閉自在に支持するヒンジであることが望ましい。
このような建具によれば、例えば、剛性を高めるためにリブなどにより補強されることにより表面に複数の突部を有するヒンジは、大型の障子を支持することが可能なので、大きなサイズの建具にあっても、より高い防火性能を備えることが可能である。
In such a fitting, it is preferable that the attachment member is a hinge that supports the sash on the frame so as to be freely opened and closed.
According to such a fitting, for example, a hinge having a plurality of protrusions on its surface by being reinforced by a rib or the like to increase rigidity can support a large sash, so that a fitting of a large size can be used. Even so, it is possible to provide higher fire protection performance.
本発明によれば、より防火性が高い建具を提供することが可能である。 ADVANTAGE OF THE INVENTION According to this invention, it is possible to provide a more highly fireproof fitting.

I have. Further, the thermally expandable graphite 9 is attached to the left and right vertical frames 33 over the entire length of the left and right vertical frames 33 on the outdoor portion of the left and right vertical frames 33.
本実施形態の建具1によれば、枠体2と障子3の框体30が対向する部位には、表面に複数の框側リブ42cを備えているヒンジ4が取り付けられているが、ヒンジ4の表面を覆う平坦部8aを備えたカバー部材8の平坦部8aに熱膨張性黒鉛9が設けられているので、十分な接着面積を確保して熱膨張性黒鉛9を備えることが可能である。このため、枠体2と框体30とが対向する部位に表面に複数の框側リブ42cを備えているヒンジ4が設けられていたとして、熱膨張性黒鉛9は外れ難く、より確実に配置しておくことが可能である。このため、枠体2と框体30とが対向する部位に火炎に対するタイトラインを連続して形成しやすいので、より防火性が高い建具1を提供することが可能である。 According to the fitting 1 of the present embodiment, a hinge 4 having a plurality of frame-side ribs 42c on its surface is attached to a portion where the frame 2 and the frame 30 of the shoji 3 face each other. Since the heat-expandable graphite 9 is provided on the flat portion 8a of the cover member 8 having the flat portion 8a covering the surface of the heat-expandable graphite 9, the heat-expandable graphite 9 can be provided while securing a sufficient bonding area. . Therefore, assuming that the hinge 4 having the plurality of frame-side ribs 42c is provided on the surface where the frame 2 and the frame 30 face each other, the thermally expandable graphite 9 is unlikely to come off and is more securely arranged. It is possible to keep. Therefore, it is easy to continuously form a tight line against the flame at a position where the frame 2 and the frame 30 face each other, so that it is possible to provide the fitting 1 having higher fire resistance.
また、熱膨張性黒鉛9は、カバー部材8の平坦部8aより表面側に突出する曲起部8e及び先端近接部8fと平坦部8aとの間に配置されているので、剥がれる方向への熱膨張性黒鉛9の移動が曲起部8eにより規制される。このため、熱膨張性黒鉛9はより剥がれにくいので、より確実に平坦部8aに留めておくことが可能である。 In addition, since the heat-expandable graphite 9 is disposed between the flat portion 8a and the bent portion 8e protruding from the flat portion 8a of the cover member 8 to the surface side, and the flat portion 8a, the heat in the direction in which the graphite 9 peels off. The movement of the expandable graphite 9 is restricted by the bent portion 8e. For this reason, since the thermally expandable graphite 9 is harder to peel off, it is possible to more reliably hold the same on the flat portion 8a.
また、枠体2と框体30との間には、平坦部8aに熱膨張性黒鉛9が設けられているカバー部材8と熱膨張性黒鉛9とが全周に繋がっているので、ほぼ全周に渡って熱膨張性黒鉛9が設けられている。このため、枠体2と框体30とが対向する部位において、ヒンジ4が設けられている部位の全域に加熱発泡材が設けられていない場合より、高い防火性を備えることが可能である。また、下枠22と下框32との間の狭い空間内にて熱膨張性黒鉛9が発泡すると、下枠22と下框32との間において発泡した熱膨張性黒鉛9が充満する。このため、たとえカバー部材8のビス止め部8b及び傾斜部8cに熱膨張性黒鉛9が設けられていなくとも、発泡した熱膨張性黒鉛9が、熱膨張性黒鉛9が設けられていない僅かな空間にも回り込んで、全周に繋がった火炎に対するタイトラインを形成することが可能である。尚、ビス止め部8b及び傾斜部8cにも熱膨張性黒鉛9を設けても良い。 Also, between the frame 2 and the frame 30, the cover member 8 having the flat portion 8a provided with the heat-expandable graphite 9 and the heat-expandable graphite 9 are connected to the entire circumference, so that almost all A thermally expandable graphite 9 is provided around the circumference. For this reason, in the part where the frame body 2 and the frame body 30 face each other, it is possible to provide higher fire protection than when the heating foam material is not provided in the entire area where the hinge 4 is provided. When the thermally expandable graphite 9 foams in a narrow space between the lower frame 22 and the lower frame 32, the thermally expandable graphite 9 foamed between the lower frame 22 and the lower frame 32 is filled. For this reason, even if the thermally expandable graphite 9 is not provided on the screw stopper 8 b and the inclined portion 8 c of the cover member 8, the foamed thermally expandable graphite 9 is slightly removed without the thermally expandable graphite 9. It is also possible to form a tight line with respect to the flame connected to the entire circumference by going into the space. Incidentally, the thermally expandable graphite 9 may be provided on the screw stopper 8b and the inclined part 8c.
また、剛性を高めるために框側リブ42cや枠側リブ41aなどにより補強されて、表面に複数の凹凸が形成されているヒンジ4であっても、熱膨張性黒鉛9を確実に備えることが可能なので、大型の障子3を支持することが可能である。このため、大きなサイズの建具にあっても、より高い防火性能を備えることが可能である。 Further, even if the hinge 4 is reinforced by the frame-side rib 42c or the frame-side rib 41a in order to increase the rigidity and the surface of the hinge 4 has a plurality of irregularities, it is possible to surely provide the heat-expandable graphite 9. Since it is possible, it is possible to support a large sash 3. For this reason, even in the case of a fitting having a large size, it is possible to provide higher fire prevention performance.
上記実施形態においては、ヒンジ4において、下框32に固定される框側固定部42側にカバー部材8と熱膨張性黒鉛9とを設けた例について説明したが、これに限らず、例えば、下枠22の枠見込面部2aに固定される枠側固定部41側にカバー部材8と熱膨張性黒鉛9とを設けても構わない。 In the above-described embodiment, the example in which the cover member 8 and the thermally expandable graphite 9 are provided on the side of the frame-side fixing portion 42 fixed to the lower frame 32 in the hinge 4 has been described. The cover member 8 and the heat-expandable graphite 9 may be provided on the side of the frame-side fixing portion 41 fixed to the frame projection surface portion 2a of the lower frame 22.
また上記実施形態においては、取付部材をヒンジとしたが、取付部材は、室内外を貫通する可能性を有する空間に設けられて、連続して加熱発泡材を設けることを遮る部材であれば、ヒンジに限るものではない。
上記実施形態においては、加熱発泡材を熱膨張性黒鉛9としたが、加熱されて膨張する耐火材であれば、熱膨張性黒鉛に限るものではない。
Further, in the above embodiment, the attachment member is a hinge, but the attachment member is provided in a space having a possibility of penetrating the inside and outside of the room, as long as it is a member that blocks continuous provision of the heating foam material, It is not limited to hinges.
In the above embodiment, the heat-expandable material is the heat-expandable graphite 9. However, the heat-expandable material is not limited to the heat-expandable graphite as long as it is a refractory material that expands when heated.
上記実施形態においては、建具1として外倒し窓用の建具1を例に挙げて説明したが、これに限らず、例えば、引き違い窓、開き窓、すべり出し窓など、枠体により形成される開口を閉塞可能な障子を備えた建具であれば構わない。 In the above embodiment, the fitting 1 for the falling window has been described as an example of the fitting 1; however, the present invention is not limited to this. For example, an opening formed by a frame, such as a sliding window, a casement window, or a sliding window. Any fitting having a shoji that can close the door may be used.
また、上記実施形態は、本発明の理解を容易にするためのものであり、本発明を限定して解釈するためのものではない。本発明は、その趣旨を逸脱することなく、変更、改良され得ると共に、本発明にはその等価物が含まれることはいうまでもない。 Further, the above-described embodiment is for facilitating understanding of the present invention, and is not for limiting and interpreting the present invention. The present invention can be changed and improved without departing from the spirit thereof, and it goes without saying that the present invention includes equivalents thereof.
