In order to move in the state, the bubbles in the moving hydrogel 5 move up along the inner surface of the glass plate 1 and are concentrated and concealed on the concave inner surface side of the upper spacer portion 2, and then the tunnel portion of the ultraviolet irradiation device. 8, the hydrogel 5 which has been irradiated and irradiated by the ultraviolet lamps 11, 11,...
Was converted into a polymerized gel to become a transparent foamable refractory material, and even when the fireproof glass body 6 taken out from the exit of the roll conveyor 9 was visually observed from the glass plates 1 and 1 side, no bubbles were observed in the plane. .

造することができる。According to the present invention, since a double-glazed structure containing water-containing gel is irradiated with ultraviolet rays simultaneously from both sides, the polymer is instantly polymerized and gelled regardless of the thickness of the structure, thereby ensuring a good transparent state. In the unlikely event that bubbles remaining in the hydrogel are also tilted before irradiation and then injected into the UV irradiation device, they are hidden on the inner surface of the upper side of the spacer, so apparent bubbles may be generated. No fireproof glass can be produced.
