Summary of the invention

In order to overcome the shortcoming that existing vacuum glass exists; the purpose of this utility model provides simple, the practical building vacuum glass plate of a kind of form of structure; thereby can realize production low-costly and in high volume; this hollow plate glass has better thermal insulation, sound insulation property and has higher wind pressure resistant strength; limit, angle are protected, have reduced the breakage rate in transportation, the installation process.

The technical scheme that realizes the utility model purpose is: the structure of this building vacuum glass plate is to be formed by stacking by two sheet glass.Between two blocks of glass, its periphery is to be not less than 3 millimeters sealing-in band with the width that the glass for bonding material forms.Zone line is uniform-distribution with the glass for bonding material and makes, and spacing is that 10 millimeters to 100 millimeters, diameter are 0.2 millimeter to 2.0 millimeters supporting pad.After vacuum seal technology, sealing-in band that the glass for bonding material is made and supporting pad two nonvolatil sealing of glass plate, and by controlling the thickness of glass for bonding, separate two glass plates the vacuum chamber that forms the yardstick that requires.Need not process, install extract opening and corresponding extract opening seal protecting device.Peripheral sealing-in band and supporting-point that the solder glass material is made can (for example typography) be finished in same operation.At last, periphery is loaded onto the matrix rubber ring, makes the building vacuum glass plate that the utility model proposes.

The beneficial effects of the utility model are, the disclosed building vacuum glass plate of (1) the utility model operation of need not finding time specially, the trouble of removed processing from, extract opening, sealing and protection extract opening being installed; Need not lay specially, supporting masses such as fixing pottery, wire, removed the laying of supporting mass, fixedly operation and material and equipment accordingly from, saved material, equipment and man-hour.Simultaneously, eliminated the possibility that these operations cause waste product.(2) the equally distributed supporting pad in mesozone with the sealing-in band of periphery, is welded into an integral body to two blocks of glass, has improved the bulk strength and the rigidity of building vacuum glass plate, has strengthened the resisting wind press capacity of building vacuum glass plate; (3) sealing-in of glass plate is to carry out in the vacuum seal stove, and high vacuum environment and high temperature move back the building vacuum glass that the gas effect can be made condition of high vacuum degree.Thereby its thermal insulation, defening effect are better; (4) Zhou Bian matrix rubber ring can effectively prevent in transportation, broken by collision in glass edge, angle in the installation process, because the limit of glass, angle are the most flimsy places of building vacuum glass plate.(5), be suitable for mechanization, produce high-quality building vacuum glass plate in enormous quantities, cheaply because product structure is simple, practical.
