The remarkable advantage of the present invention is that the edge folding makes the vacuum glass form a three-dimensional force-bearing structure, thereby significantly enhancing the bending and flexural strength, and significantly enhancing the peripheral strength of the vacuum glass. The unique structure and manufacturing method of hemming, multiple vacuum layers, and high-thickness vacuum layers endow the product with excellent thermal insulation performance and excellent safety and reliability. So as to solve the bottleneck and chronic problem of low safety of the existing vacuum glass which seriously restricts the development of the industry, it is very important for the development of projects, products and industries. The durability of the product is more than ten times that of the existing vacuum glass, and it can truly achieve the same life as the building. As an integrated product of structure and function, it has a broad application market. Through the adjustment of the height and thickness of the hem, the thickness of the vacuum layer, the number of layers and the degree of vacuum, the bending resistance, bending resistance, impact strength and thermal insulation performance are set accordingly. %, comprehensive requirements for curtain walls, walls, roofs, doors and windows for passive and zero-energy buildings.
