Composite vacuum glass with large-spacing hollow layer and vacuum glass component

The utility model discloses composite vacuum glass with a large-spacing hollow layer and a vacuum glass component. The vacuum glass comprises two vacuum glass substrates, a sealing edge and a supporting object, the sealing edge is arranged at the peripheral edge position between the two vacuum glass substrates, the two vacuum glass substrates and the sealing edge jointly define a vacuum layer, a glass unit is further arranged on the outer side of one vacuum glass substrate, and the supporting object is arranged on the outer side of the other vacuum glass substrate. A hollow layer is arranged between the vacuum glass substrate and the adjacent glass unit, a plurality of spacing assemblies are arranged on the peripheral edge of the hollow layer, the plurality of spacing assemblies are connected end to end to form a ring, the vacuum glass substrate, the glass unit and the plurality of spacing assemblies enclose to form the large-spacing hollow layer, the thickness T of the large-spacing hollow layer is 30-100 mm
