Description of the invention (1) [Application fields in the industry] (Please read the cautions on the back and fill out this page) The present invention is about the gap between the pair of plate glass with the space retaining member sandwiched between them. Around the entire periphery of the outer edges of the two sheets of glass, a heat-melt-type outer peripheral sealing portion is provided, so that the space between the two sheets of glass is hermetically sealed in a decompressed state. [Advanced technology] As a sheet glass with higher thermal insulation performance than a sheet glass, it is a conventional multilayer glass that is tied between a pair of sheet glass and integrated as an air layer as a thermal insulation layer. However, since such a glass plate has a large thickness and contains an elastic pad, it has a problem that the appearance is easily damaged. Here, I think that if I want to have a thinner thickness and higher heat insulation, I want to arrange a plurality of spacer members between a pair of sheet glass, and individually surround the entire periphery between the outer edges of the two sheet glass. It is made integrally with a heat-melted outer peripheral sealed portion (for example, low-melting glass), and the aforementioned gap portion is made in a reduced pressure state to make a glass plate that is thinner and has a lower heat flow rate. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, and regarding the formation of the above-mentioned peripheral sealed portion, the low-melting-point glass solder (paste) is placed on the outer peripheral portion of the two sheets of glass and heated to the aforementioned low-melting point. Above the melting point of glass, the low-melting glass after melting is adhered between the outer peripheral portions of the two sheets of glass, and when the temperature is returned to normal temperature, the hardened low-melting glass forms the outer sealed portion. This kind of conventional glass plate, as a pair of plate glass, basically uses the same type of plate glass (for example, a float plate). This paper size is applicable to the Chinese National Standard (CNS) A4 specification ( 210x 297 mm) A7 B7 V. Description of the invention (2) Glass), or when used in a fire-resistant partition, the panel glass on either side is made of reticular glass. (Please read the note on the back 8 and fill in this page first.) However, the conventional glass sheet mentioned above has the following problems. ‘That is, when the aforementioned outer peripheral sealed portion is formed, it is necessary to raise the ambient temperature of the glass plate as described above and then return to normal temperature. At this time, a pair of plate glass should expand and contract according to the surrounding temperature. The expansion and contraction of such sheet glass is affected by individual linear expansion coefficients. For example, when the linear expansion coefficients of a pair of sheet glass are different, when the ambient air temperature rises, the sheet glass with a larger linear expansion coefficient has a larger expansion amount. When the ambient air temperature returns to normal temperature, the two sheets of glass individually shrink back to their original size. When the outer peripheral edge portions of the two sheets of glass are connected to each other at the hermetically sealed portion of the preface, the two sheets of glass are connected under different temperature expansion conditions. When the temperature returns to normal temperature, the plate glass with a larger linear expansion coefficient shrinks more than the other plate glass. The result is printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. There will be two sheets of glass that are bent due to the difference in the amount of shrinkage, and the glass sheet will be bent. When the amount of bending is too large, the internal pressure may be reduced. At that time, the glass plate was broken due to the atmospheric pressure. As described above, according to the conventional glass sheet, if a pair of sheet glass is used separately, two sheets of glass may be bent and broken, and even if there is no damage, internal stress will remain in the two sheets of glass, and Can not reach a certain intensity and so on. This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) A7 _____B7____ V. Description of the invention (3) The purpose of the present invention is to eliminate the aforementioned problems and provide a plate glass with different combined expansion ratios. The glass plate can be easily obtained with appropriate strength, and can be in a constant state for a long time even when the interior is decompressed. [Disclosure of the invention] The characteristic structure of the glass plate of the present invention is as follows. As for the glass plate in the first patent application scope, as shown in Fig. 1, it is designed to 'interpose the space maintaining member between a pair of plate glasses while surrounding the entire periphery of the two plate glasses'. There is a heat-sealed outer peripheral sealed portion, so that the space between the two sheets of glass is a closed glass plate under reduced pressure; it is characterized in that among the pair of plate glasses, The coefficient of linear expansion (αΐ) and the coefficient of linear expansion (α 2) of the glass on the other side are set to satisfy: (α 1-a 2) X △ TS 6 X 1 0-5 …… (1) α1 > α2, α 1: —The linear expansion coefficient of the glass on the side (/ ° C) “α 2: The coefficient of linear expansion of the glass on the other side (/ ° C), △ T: (the solidification temperature of the outer sealed portion -Ambient temperature of glass plate) (° C), as long as it has such a structure, among the aforementioned pair of plate glass, the coefficient of linear expansion of the glass on one side and the coefficient of linear expansion of the glass on the other side are used.

It is 3 2 0 ~ 3 0 0 t), or after the low-melting glass 8 for forming a sealing portion is coated on the protruding portion 5, the plate glass 1 B on the other side is overlapped after being sufficiently dried. In this embodiment, the drawing glass 3B on the other side of the glass plate 1B is formed in advance as the suction port 3a. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs [3] The two sheets of glass IA, 1B are heated (around ambient air temperature of 50 ° C), and the aforementioned low-melting glass 8 for forming the sealing portion is melted and cooled. To normal temperature (20 ° C in this embodiment). Thereby, the low-melting glass 8 for sealing portion formation is hardened to form a sealing portion (see FIG. 5). [4] After the air in the gap portion V is drawn through the suction port 3a, the suction portion is sealed to form a glass plate P (see Figs. 6 and 7). In addition, regarding the glass plate P of the present invention, the Chinese national standard (CNS) A4 specification (210 X 297 mm) can be applied to the paper size of the decompression ring as follows: -11-A7 B7 V. Description of the invention (9) Manufacturing. _ (Please read the notes on the back first and fill in this page) [1] First, as shown in Figure 8, a spacer 2 is placed on a certain position of the glass 1 A on one side. _ [2] As shown in Fig. 9, under a reduced pressure environment (for example, in a vacuum furnace), the projection 5 is coated with a low-melting glass 8 for forming a seal portion (the softening point is 3 2 0 to 3 9 0 ° C) On one side of the sheet glass_1 A, overlap the other side of the sheet glass 1 B. In this case, it is not necessary to provide an extraction port 3 a on the other side of the glass 1 B. [3] Furthermore, as shown in FIG. 10, the two sheets of glass 1A and 1B are heated (the ambient air temperature is about 50 t), the low-melting glass 8 for forming the seal portion is melted, and then cooled to Normal temperature (20 ° C in this embodiment). Thereby, the low-melting glass 8 for sealing portion formation is hardened to form a sealing portion. According to the above-mentioned process, as shown in Fig. 10, the glass plate P having the reduced-pressure void portion V is formed. (Evaluation of glass plates) Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs Generally, when the linear expansion coefficients of the two sheets of glass 1 A and 1 B are different, when the sealing portion 4 is formed, the two sheets of glass are formed. When 1 A, 1 B is cooled from a warmed state to a normal temperature state, the two sheets of glass 1 A, 1 B cause different shrinkage amounts. This difference in the amount of shrinkage causes the glass plate P to bend, causing breakage. But what about the glass sheet of the present invention? 'Although it is a combination of plate glass 1 A and 1 B with different thermal expansion coefficients', it is a structure that satisfies the above formula (1) or (2), so it is possible to prevent the internal stress from increasing.
