溝部２４にユニット１を嵌合し、ユニットの下端の溝部
２４の底２４ａとの間には珪酸カルシウム等のセツティ
ングブロック２５を介在せしめてユニットヲ支持する。The unit 1 is fitted into the groove 24, and a setting block 25 made of calcium silicate or the like is interposed between the bottom 24a of the groove 24 at the lower end of the unit to support the unit.
ユニット１の左右の側面と図示しないが上部と溝部２４
との間には間隙充填材２６を充填し支持する。The left and right sides of the unit 1, the upper part (not shown), and the groove 24
A gap filler 26 is filled and supported between the two.
充填材２６としては例えばイソラント・パブコック社製
の商品名「カオウール」の綿状品の如きセラミックファ
イバーを用いた。As the filler 26, a ceramic fiber such as a cotton-like product manufactured by Isolant Pubcock under the trade name "Kao Wool" was used.
ユニット１の一方のガラス板２周辺と起枠２３との間に
は不燃性充填材２７を充填して支持せしめ、不燃性充填

適宜種類混合したものを用い、特にカルシウムの化合物
は高温状態でガラスと反応して接合層を形成することか
ら、不燃性充填材にトけるカルシウム化合物の含有量が
高いことが好ましい。A noncombustible filler 27 is filled between the periphery of one glass plate 2 of the unit 1 and the frame 23 for support. Examples of the noncombustible filler include glass putty, fireclay, asbestos, glass fiber, and plaster. The content of calcium compounds in the non-combustible filler is low, especially since calcium compounds react with glass at high temperatures to form a bonding layer. Preferably high.
ユニット１の他方のガラス板３の周辺外側部には押縁２
８をビス２９で溝部２４端、即ち開口部２２端に固着し
、との押縁２８とガラス板３周辺部間には上記と同様に

従って現場施工は極めて簡易となり、作業もし易く、作
業時間も大幅に短縮でき、作業性、施工性は極めて良好
である。Therefore, on-site construction is extremely simple, the work is easy, the work time can be significantly shortened, and the workability and construction efficiency are extremely good.
そして金属線入りガラス板の複数及びスペーサ反意は耐
熱性接着材で接合されているため、火災時にガラス板が
相当軟化しても剛性が保たれ、従って変形に伴なう枠体
からの抜は出しは従来に比し遅延することとなる。Furthermore, since the plurality of glass plates containing metal wires and the spacers are bonded together with a heat-resistant adhesive, their rigidity is maintained even if the glass plates become considerably softened in the event of a fire, so they can be pulled out of the frame due to deformation. The launch will be delayed compared to before.
ところで火災時防火扉２０は加熱され、ユニット１のガ
ラス板２，３の火災側は火災にさらされ、或いは周囲の
温度で加熱される。By the way, in the event of a fire, the fire door 20 is heated, and the fire side of the glass plates 2, 3 of the unit 1 is exposed to the fire or heated at the ambient temperature.
これに伴なって気密の中間層８内の気体は膨張し、ガラ
ス板の軟化等と併せ、或いは単純に気体膨張による圧力
で外側に湾曲変形し、最後には破損する虞もある。Along with this, the gas in the airtight intermediate layer 8 expands, which may cause the glass plate to soften, or simply be bent outward due to the pressure caused by the gas expansion, and may eventually break.
しかしながら実施例のように中間層８を通孔５゜６とで
外気に連通させ、通孔６を熱易融性物質で閉塞した構造
とすれば、常温では中間層８を気密に保持しているが、
火災時の加熱、温度上昇で熱易融性物質１４は溶解し、
これにより通孔６の閉塞は解除されて開口し、通孔５、
空間７、通孔６を介して中間層８は外気と連通ずること
となる。However, if the intermediate layer 8 is made to communicate with the outside air through the holes 5 and 6 and the holes 6 are closed with a thermofusible substance as in the embodiment, the intermediate layer 8 can be kept airtight at room temperature. There are, but
The thermofusible substance 14 melts due to heating and temperature rise during a fire,
As a result, the through hole 6 is unblocked and opened, and the through hole 5,
The intermediate layer 8 communicates with the outside air via the space 7 and the through hole 6.
従って中間層８内の膨張した気体は排出されて内部は大
気圧となり、ガラス板２，３への圧力はなくなり、これ
の圧力に起因する変形、破損は防止される。Therefore, the expanded gas in the intermediate layer 8 is discharged and the inside becomes atmospheric pressure, so that no pressure is applied to the glass plates 2 and 3, and deformation and damage caused by the pressure are prevented.
従ってガラス自体の軟化、これの垂れによって上辺部が
枠上部から脱落し、開口を生成する迄ガラス板は健在に
火災遮断機能を発揮することとなる。Therefore, the glass plate continues to perform its fire-blocking function until the glass itself softens and sag, causing the top side to fall off the top of the frame and create an opening.
かくして平常時においては複層ガラス本来の利点である
断熱防音機能を発揮し、しかも火災時の火災遮断機能を
長時間に亘り維持し、火災遮断性能、耐火性、防火性に
優れる防火用窓ガラスを得ることができる。In this way, in normal times, it exhibits the heat and sound insulation function that is the inherent advantage of double-glazed glass, and also maintains its fire-blocking function in the event of a fire for a long time, making it a fire-prevention window glass that has excellent fire-blocking performance, fire resistance, and fire prevention properties. can be obtained.
以上は防火扉にユニットヲ取り付けたが、防火用構造体
は任意で、本考案にかかる複層ガラスコニットの施工す
る対象は任意である。Although the unit is attached to the fire door in the above, the fire prevention structure is arbitrary, and the object to which the double-glazed conite according to the present invention is constructed is arbitrary.
以上要するに、火災時には、スプーサに設けられた通孔
の熱易融性物質が溶けることにより、密封された中間層
気体が外気と連通ずる。In short, in the event of a fire, the heat-fusible material in the through hole provided in the spouser melts, allowing the sealed intermediate layer gas to communicate with the outside air.

用窓ガラスとして優れた複層ガラスを得ることができる
。Therefore, the gas in the intermediate layer expands and prevents the glass plate from bending and breaking, and since the metal wire-containing glass plate and spacer are bonded together with a heat-resistant adhesive, the glass plate will not soften considerably in the event of a fire. Therefore, removal from the frame due to deformation is significantly delayed compared to conventional methods, and the inherent fire-blocking performance of the glass plate and its support is maintained over a long period of time. It is possible to obtain double-glazed glass that is excellent as a fire prevention window glass.
