となっている。This foamable fire-resistant glass 1 is a foam material 11 having a heat-foaming property.
A plurality of glass plates (12) are laminated through the above, and the foam material (11) foams due to heating of a fire such as a fire and expands its volume, thereby exhibiting heat resistance. Further, although the foam material 11 is usually transparent, it becomes opaque due to foaming and also has an effect of blocking radiant heat. And
Due to its thickness, weight, etc., this foamable fireproof glass 1 has a structure in which it is mounted using a mounting frame 2 fixed to a mounting portion 3 such as a window or door as shown in FIG. As shown in FIG. 7, the structure in which the peripheral edge of the foamable fireproof glass 1 is inserted into the groove 2'provided in the mounting frame 2 and fixed by the fixing member 4 such as caulking material or standard gasket provided in the groove 2 ' Has become.

方法を柔軟にすれば、このようなクラックの発生を制御
できることも実験によって確認されている。However, in the conventional mounting structure shown in FIGS. 6 and 7, if the width of the groove 2'is narrow, expansion of the foamable refractory glass 1 in the groove 2'is prevented on the way as shown in FIG. Therefore, stress concentrates on the inner and outer boundary portions of the groove 2'of the foamable refractory glass 1 and the crack 5 is generated. This problem occurs not only in relation to the width of the groove 2 ', but also when the fixing material 4 is a standard gasket having high hardness. The glass crack itself is
It will inevitably occur when heated,
Unnatural cracks due to such stress concentration are heated,
It has been confirmed by an experiment that heat is likely to pass through because a large fault will be generated soon and a large fault will be formed, and the fire resistance of the foamable fire-resistant glass 1 will be significantly reduced. It has also been confirmed by experiments that the generation of such cracks can be controlled by making the fixing method flexible.

なくなる。In order to prevent cracks generated due to such stress concentration, it is necessary to take measures such as expanding the width of the groove 2'and changing the material of the fixing material 4, but with this, the groove 2'and the fixing material 4 are also accompanied. It also becomes necessary to consider how to prevent the deterioration of the surrounding fire resistance.
本発明は前述の問題点を解決するためになされたもの
で、その目的は、発泡性耐火ガラスへの応力集中を緩和
し、なおかつ取付構造の耐火性を向上することにある。The present invention has been made to solve the above-mentioned problems, and an object thereof is to alleviate the stress concentration on the foamable refractory glass and to improve the fire resistance of the mounting structure.

性材としたものである。The attachment structure of the foamable fireproof glass according to the present invention is such that the peripheral edge of the foamable fireproof glass obtained by laminating a plurality of glass plates through a foam material having a heat-foaming property is inserted into the groove of the attachment frame, and is inserted into the groove. In a mounting structure of foamable fireproof glass, which is formed by fixing foamable fireproof glass with a fixed material having fireproofness, the groove has a width that allows expansion of the foamable fireproof glass, and the fixing material is foamable fireproof glass. It is an elastic material that shrinks following the expansion of the.

The stress is not concentrated on the inner and outer boundary parts of the glass, and no unnatural cracks are generated in the foamable fireproof glass.
以下、本発明の実施例を第１図〜第５図に基づいて説明

ている。In the embodiment shown in FIG. 1, the width of the groove 2'of the mounting frame 2 is enlarged to form a gap that allows expansion of the foamable fireproof glass 1,
The fixing material 4 made of the elastic material 41 is press-fitted into this gap. As the elastic member 41, a leaf spring in which a metal plate as shown in FIG. 3 is bent in a relative direction is used. However, a wire spring in which a metal wire is similarly formed, and a metal plate as shown in FIG. 4 is bent in a zigzag manner. It is also possible to use a leaf spring, a coil spring or the like. The elastic material 41 is provided in the groove 2'at regular intervals, and the elasticity thereof presses the foamable refractory glass 1 to one side of the groove 2 '. The groove 2'around the elastic material 41 is filled with the fixing material 4 made of a refractory material 42 such as asbestos or glass wool, and the upper part of the groove 2'is covered with the elastic material 41 and the refractory material 42. A fixing material 4 made of caulking material 43 is provided.

Therefore, the fixing strength is not reduced as compared with the conventional one.

を防止している。FIG. 2 shows the heating state of the embodiment shown in FIG.
The expanded foamed refractory glass 1 is shown contracting the elastic material 41. When the foamable refractory glass 1 is heated by a fire or the like, the foam material 11 foams (glass plate 12
The thermal expansion of the glass also occurs.) The expandable refractory glass 1 expands,
The elastic material 41 contracts by this expansion, but retains the foamable refractory glass 1 fixed by its elasticity. Therefore, the foamable refractory glass 1 does not rattle, and
The concentration of stress causing the crack 5 as shown in FIG. 8 cannot occur. Further, since the elastic material 41 and the outermost glass plate 12 of the foamable fireproof glass 1 are only partially in pressure contact with each other, the friction is weak and the outermost glass plate 12 is not cracked. The refractory material 42 seals the gap between the foamable refractory glass plate 1 and the groove 2'when the foamable refractory glass plate 1 is expanded, thereby preventing the fire resistance from deteriorating.

ため、取付作業が簡便化される利点がある。FIG. 5 shows an embodiment in which the elastic material 41 shown in FIG. 1 is replaced by a leaf spring or the like and a tube-shaped refractory gasket is used. According to this embodiment, since the elastic member 41 made of a fireproof gasket can be press-fitted and attached along the groove 2 ', there is an advantage that the attaching work is simplified.
