The application relates to the technical field of
toughened glass, and discloses a multilayer composite laminated
toughened glass, which comprises inner layer glass and outer layer glass, the two sides of the inner layer glass are provided with the outer layer glass, through holes are formed in the surface edges of the inner layer glass and the outer layer glass, connecting seats are arranged at the through holes of the inner layer glass, bolt columns are welded on the two sides of the connecting seats, and the bolt columns are penetrated into the through holes of the outer layer glass. In the application, the
functional module layer is arranged between the outer layer glass and the inner layer glass, the connecting seat, the bolt column and the double-nut structure at the through hole of the inner layer glass are matched, the
functional module layer can be quickly disassembled or replaced, the outer layer glass and the inner layer glass can be separated by only rotating the double nuts, the overall structure of the glass does not need to be damaged, the difficulty and the
time cost of replacement are greatly reduced, the glass always maintains the best functional state, and remarkable economic and
environmental protection benefits are achieved.
