Abstract: A glass panel unit assembly includes a pair of glass substrates arranged to face each other, a peripheral wall, a partition, an air passage, and an evacuation port. The peripheral wall has a frame shape and is provided between the pair of glass substrates. The partition partitions an internal space, surrounded with the pair of glass substrates and the peripheral wall, into a first space and a second space. The air passage connects the first space and the second space together. The evacuation port connects the second space to an external environment. The partition has a broader width than the peripheral wall.

Abstract: A method for manufacturing a glass panel unit, which reduces the amount of a getter material to enable a gettering ability to be realized at a relatively low temperature less likely to cause damage. The method includes a step of producing a getter material by heating an unprocessed getter material at a temperature higher than a prescribed temperature Te; a step of producing a preassembled component including a first and second glass pane, a heat-fusible sealing material, an internal space, and a gas adsorbent containing the getter material, and an evacuation port; a step of forming a frame body hermetically bonding the first glass pane and the second glass pane together by melting the heat-fusible sealing material with heat; and a step of heating the gas adsorbent at the prescribed temperature Te while the internal space is evacuated by exhausting air in the internal space through the evacuation port.

Abstract: A glass panel unit manufacturing method includes a punching step and a pillar mounting step. In the punching step, a punch punches at least one of a plurality of portions from a base material of a sheet to form at least one pillar. Each of the plurality of portions is surrounded by a corresponding one of a plurality of loop-shaped grooves in the base material. In the pillar mounting step, the at least one pillar is mounted on a surface of a first substrate including a glass pane.

Abstract: A glass panel unit having an inner space at a reduced pressure and a building component including such a glass panel unit are provided such that no traces of an exhaust pipe are left on their outer surface. To achieve this, a glass panel unit manufacturing method includes a bonding step, a pressure reducing step, and a sealing step. The bonding step includes bonding together a first substrate (10) and a second substrate (20) with a first sealant (410) to create an inner space (510). The pressure reducing step includes producing a reduced pressure in the inner space (510) through an exhaust port (50) that the first substrate (10) has. The sealing step includes melting a second sealant (420) inserted into the exhaust port (50) by locally heating the second sealant (420), and deforming the second sealant (420) by pressing the second sealant (420) toward the second substrate (20), to seal the exhaust port (50) up with the second sealant (420) melted and deformed. A glass panel unit manufacturing method includes a bonding step, a pressure reducing step, and a sealing step. The bonding step includes bonding together a first substrate and a second substrate with a first sealant to create an inner space. The pressure reducing step includes producing a reduced pressure in the inner space through an exhaust port that the first substrate has. The sealing step includes melting a second sealant inserted into the exhaust port by locally heating the second sealant, and deforming the second sealant by pressing the second sealant toward the second substrate, to seal the exhaust port up with the second sealant melted and deformed.

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

Abstract: The glass panel unit includes a first glass substrate, a second glass substrate, a sealing member, an inside space, and a plurality of spacers. The inside space is hermetically enclosed by the first glass substrate, the second glass substrate, and the sealing member, and has reduced pressure. The plurality of spacers are placed in the inside space. At least one of the first glass substrate and the second glass substrate is a wire-embedded glass panel with a wire structure embedded therein. The plurality of spacers are arranged so as to overlap with part of the wire structure in a plan view.

Abstract: A first glass substrate and a second glass substrate which are placed to face each other with a seal member in-between are bonded to each other with the seal member. Subsequently, the first glass substrate, the seal member, and the second glass substrate are cut collectively along a cut plane passing through the seal member from one of the first glass substrate and the second glass substrate bonded to each other. Thereby, a glass panel unit is manufactured.
