[0005]
1). In a portion where the setting block 7a 'is not provided, the lower surface of the double-glazed glass 5 comes into contact with the outside air, so that there is a problem that the temperature is apt to decrease greatly in winter, the amount of glass condensation is increased, and freezing is easily promoted. When the amount of dew condensation on the glass increases or freezes, the dew condensation water W is less likely to be drained, and the dew condensation water W easily drops into the room.
[0006]
2). Even in a portion of the setting block 7a ', the water-side tip of the portion along the lower surface of the glass of the setting block 7a' is located below the water-side edge of the sealing spacer 4 by a distance c, and is mainly composed of aluminum. This does not completely cover the portion of the sealing spacer 4 to be formed, and also in this respect, there is a problem that the temperature of the lower surface of the glass tends to decrease, the amount of dew condensation in the glass increases, and the freezing is easily promoted.
[0007]
3). Since the water-side end of the setting block 7a 'has a vertical surface a, the condensed water W easily accumulates in this portion, and the condensed water W easily accumulates and freezes. There is a problem that it becomes easier.
[0008]
4). When the dew condensation water W flows under the support member 12 made of a metal such as aluminum, there is a problem that freezing of the dew condensation water is promoted by cold heat transferred from the support member 12.
[0009]
The present invention has been made in view of the above-mentioned points, and it is possible to drastically reduce the condensation of dew condensation water inside a room even in a weather such as a cold wave in winter when a day below the freezing point continues. It is an object of the present invention to provide a drainage structure.
