A vacuum glass panel includes a first glass plate (10), a second glass plate (20) facing the first glass plate (10), a frame member (30) having a frame shape and bonding the first glass plate (10) to the second glass plate (20), and a heat reflective film (11) disposed on an inner surface of the first glass plate (10). A vacuum space (50) is provided between the first glass plate (10) and the second glass plate (20). The heat reflective film (11) separates the first glass plate (10) from the vacuum space (50) without a gap. The frame member (30) is in contact with the first glass plate (10).

The multiple pane includes: a first glass panel; a second glass panel disposed facing the first glass panel with a predetermined interval in-between; and a hermetically-bonding member hermetically bonding peripheries of the first glass panel and the second glass panel to form a hermetically-enclosed space between the first glass panel and the second glass panel. The multiple pane further includes an adsorbing member (5) which is fixed on a surface of the first glass panel so as to be inside the hermetically-enclosed space, has a height equal to or less than a length of the predetermined interval, and is for adsorbing a gas inside the hermetically-enclosed space. The hermetically-enclosed space is made to be in a reduced-pressure state. Consequently, it is possible to facilitate arrangement of the adsorbing member, and therefore provide a high-quality multiple pane.

An object would be to propose a glass panel unit with improved thermally insulating and fireproof properties as well as improved appearance, and a glass window including the same. The glass panel unit includes a first glass substrate (1), a second glass substrate (2), a sealing member (3), an inside space (4), and a plurality of spacers (5). The inside space (4) is hermetically enclosed by the first glass substrate (1), the second glass substrate (2), and the sealing member (3), and has reduced pressure. The plurality of spacers (5) are placed in the inside space (4).

An object of the present invention would be to propose a glass panel unit which does not have an outlet and an evacuation pipe but has improved thermal insulating properties. The glass panel unit (10) of one aspect according to the present invention is a predetermined part separated from a completed assembly (110) obtained by subjecting a temporary assembly (100) to a predetermined process. In the temporary assembly (100), the inside space (500) enclosed by the first and second glass substrates (200, 300) and the frame (410) is divided into the first space (510) and the second space (520) with the partition (420) and the gas adsorbent (60) is inside the first space (510). The predetermined process includes: converting the first space (510) into the evacuated space (50) by evacuating the first space (510) through the gas passage (600), the second space (520), and the outlet (700); and changing a shape of the partition (420) to close the gas passage (600) to form the seal (40) enclosing the evacuated space (50). The predetermined part includes: a first and second glass panels (20, 30) being parts of the first and second glass substrates (200, 300); the seal (40); the evacuated space (50); and the gas adsorbent (60).
摘要:
An object would be to propose a manufacturing method for glass panel unit enabling efficient manufacture of a glass panel unit with desired shape and dimensions. A first glass substrate (1) and a second glass substrate (2) which are placed to face each other with a seal member (3) in-between are bonded to each other with the seal member (3). Subsequently, the first glass substrate (1), the seal member (3), and the second glass substrate (2) are cut collectively along a cut plane (900) passing through the seal member (3) from one of the first glass substrate (1) and the second glass substrate (2) bonded to each other. Thereby, a glass panel unit is manufactured. It is preferable that an inside space (4) with thermally insulating properties is formed between the first glass substrate (1) and the second glass substrate (2).
摘要:
An object would be to efficiently manufacture a glass panel unit where one or more spacers are sandwiched between a pair of glass substrates. A first glass substrate (11), a die (2) including a penetrating space (21), a seat member (3), and a punching member (4) are set so as to be arranged in this order. Subsequently, the seat member (3) is punched by the punching member (4) to remove part from the seat member (3) through the penetrating space (21) of the die (2). The part removed, is placed on the first glass substrate (11) by the punching member (4) so as to allow the part to serve as at least one spacer. Thereafter, the second glass substrate is placed on the first glass substrate (11) with the at least one spacer in-between to form a glass panel unit.
