  As shown in FIG. 17, in the conventional double-layer glass, a spacer 90 containing a desiccant is bonded to the inner side surfaces of the glasses 91a and 91b with primary seals 92 and 92, and between the glasses 91a and 91b on the outer peripheral side of the spacer 90. A secondary seal 93 is filled in the gap and bonded to form an air layer 94 sealed between the glasses. In such a conventional double-glazed glass, the inner surfaces of the glasses 91a and 91b are only bonded by primary and secondary seals, so that interlayer displacement is likely to occur between the glasses, and the seals 92 and 93 are cut off accordingly. Water vapor may enter the air layer 94 between the glasses. Further, when the glass is a glass with a mesh 95, the mesh 95 is exposed to the glass edge 96, so that it was necessary to treat the glass edge 96 with rust. Further, since the amount of the secondary seal 93 is large and the secondary seal 93 is exposed on the outer peripheral surface of the multilayer glass, the secondary seal 93 is melted and a combustible gas is generated in a fire, and the combustible gas is ignited.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a first embodiment of a multilayer glass 20 of the present invention. The double-glazed glass 20 is composed of two glasses 1a and 1b, a spacer 9 disposed between the glass 1a and 1b at the four-round edges of the glasses 1a and 1b, and a spacer 9 at the four-edge of the glasses 1a and 1b. And an edge member 2 disposed on the outer peripheral side of the glass, and an air layer 21 sealed between the glasses 1a and 1b is formed. One glass 1a is a glass containing a net 22.
The spacer 9 is a thin aluminum plate formed into a cylindrical shape by roll forming, the desiccant 8 is put inside, a vent hole 39 is provided on the inner peripheral wall, and a seam 23 is provided on the outer peripheral side. have. The spacer 9 is bonded to the inner side surfaces 6 and 6 of the respective glasses 1a and 1b by primary sealing materials 10 and 10. In addition, the spacer 9 can use what is used for the conventional multilayer glass as it is.
The edge member 2 is formed by roll forming a stainless steel plate, and has a trapezoidal shape that extends into the gap between the bases 3 and 3 facing the small openings 5 and 5 of the glasses 1a and 1b and the glasses 1a and 1b. The extending portion 4 is provided. A gas vent 24 is provided at the top of the extended portion 4 in at least one position in the longitudinal direction, and the gas vent 24 is closed with a lid 25 formed of resin, wax or the like that melts with heat in the event of a fire. . A secondary sealing material 7 is filled in the gap between the small openings 5 and 5 and the base portions 3 and 3 of the glass 1a and 1b and the gap between the inner side surfaces 6 and 6 of the glass 1a and 1b and the extension portion 4. .

  The multilayer glass 20 is manufactured in such a manner that the primary sealing materials 10 and 10 are attached to both side surfaces of the spacer 9, the glass 1a and 1b are pressed from both sides of the spacer 9, and the spacer 9 is pressed by the primary sealing materials 10 and 10 into the glass 1a. , 1b are bonded to the inner side surfaces 6 and 6. Thereafter, the secondary sealant 7 is filled in the gap between the glass 1a and 1b on the outer peripheral side of the spacer 9, and the edge member 2 is pressed from the outer peripheral side. The secondary sealing material 7 protrudes to the small openings 5 and 5 side of the glass 1a and 1b when the extended portion 4 of the edge member 2 is inserted between the glasses 1a and 1b, and the extended portion 4 and the base portion 3 of the edge member 2 are inserted. , 3 are continuously bonded by the secondary sealant 7 to the inner side surfaces 6 and 6 and the small openings 5 and 5 of the glass 1a and 1b.

  In this way, the double-glazed glass 20 is bonded to the base portions 3 and 3 and the extension portion 4 of the edge member 2 by the secondary sealing material 7 that continues the small openings 5 and 5 and the inner side surfaces 6 and 6 of the glasses 1a and 1b. By doing so, it can prevent reliably that the sealing materials 7 and 10 are cut and water vapor enters between the glasses 1a and 1b. Moreover, the adhesive strength of glass 1a, 1b improves, and the interlayer displacement between glass 1a, 1b can be prevented. Even when the glass 1a is a glass 22 with a mesh 22, since the edge 5 of the glass 1a is covered with the secondary sealing material 7 and the base 3 of the edge member 2, there is no need to perform rust prevention treatment. Furthermore, since the extension part 4 of the edge member 2 is inserted into the gap between the glasses 1a and 1b, the amount of the secondary sealing material 7 can be reduced, so that the cost can be reduced and the secondary sealing material 7 can be used in a fire. Since the combustible gas generated by melting is also reduced, the fireproof performance can be improved. Furthermore, since the secondary sealing material 7 is covered with the edge member 2 made of stainless steel, the secondary sealing material 7 can be prevented from melting and firing. Further, in the event of a fire, the gas in the air layer 21 between the glasses 1a and 1b expands. However, the lid 25 melts due to the heat of the fire, and the gas vent hole 24 of the edge member 2 opens, and the expanded gas passes through the gas vent hole 24. Since it comes off, it is possible to suppress the glass 1a and 1b from being deformed so as to swell. Since the secondary sealing material 7 is covered with the edge member 2, the secondary sealing material 7 can be prevented from aging. Further, the desiccant 8 provided in the spacer 9 absorbs moisture between the glasses 1a and 1b with the desiccant 8 and prevents condensation on the inner side surfaces 6 and 6 of the glasses 1a and 1b.

With. The outer shoji 18a and the inner shoji 18b are composed of an upper eaves 13a, a lower eaves 13b, a door-end eaves 13c, and a summoning eaves 13d, and a multi-layer glass 20 is incorporated therein. This sash is provided with the multilayer glass 20 of the first embodiment described above, so that it is possible to reliably prevent the sealing material from breaking and water vapor from entering between the glasses, and to prevent interlayer displacement between the glasses. The effect that the fireproof performance can be improved is obtained.
