Problems solved by technology

like Figure 13 , the original vacuum glass has a natural defect of uneven stress distribution, which is easy to cause glass breakage, and the structure of composite vacuum glass amplifies this defect
Because there is a closed cavity in the composite vacuum glass, when the temperature of the gas in the closed cavity changes greatly due to solar radiation, the air pressure in the cavity will also change greatly, which brings Concave-convex deformation occurs on the glass surface, and this deformation will cause the vacuum glass to be subject to greater stress impact, which will eventually aggravate the potential risk of vacuum glass breakage

Embodiment Construction

[0039] Such as figure 1 The composite vacuum glass with double-hollow suspension film shown includes outer glass 2, outer warm edge spacer frame 7.2, middle cover plate frame 6, optical plastic film 1, stretch film frame 4, and inner warm edge spacer frame 7.1 and vacuum glass3. The optical plastic film 1 is fixed on the inner side of the vacuum glass 3 by the stretch film frame 4, and is surrounded by a warm-side spacer frame (that is, an inner warm-side spacer frame 7.1) outside the cavity formed by the optical plastic film and the vacuum glass. The center cover frame 6 is installed on the inner warm edge spacer frame, and then the warm edge spacer frame of the same structure (that is, the outer warm edge spacer frame 7.2) is installed on the center cover plate frame and the outer glass 2, and finally the optical plastic film 1 separates the inner cavity formed by the outer glass 2 and the vacuum glass 3 into a buffer double hollow inner cavity for offsetting the stress im...

Abstract

Disclosed is composite vacuum glass with a dual-hollowed suspension membrane. The structure from the outer side to the inner side is configured into external glass, an outside warm edge parting strip frame, a halving cover plate frame, an optical plastic membrane, a stretching membrane frame, an inside warm edge parting strip frame and vacuum glass. The optical plastic membrane is fixed to the inner side of the vacuum glass through the stretching membrane frame. The outer side of a cavity formed by the optical plastic membrane and the vacuum glass is defined by the inside warm edge parting strip frame. The halving cover plate frame is arranged on the inside warm edge parting strip frame, then, the outside warm edge parting strip frame of the same structure as the inside warm edge parting strip frame is additionally arranged between the halving cover plate frame and the external glass, and finally the optical plastic membrane is used for forming a buffering dual-hollow inner cavity for compensating for stress impact caused by temperature and wind pressure. The excellent heat insulation performance of the vacuum glass is further improved, and use is safer and more reliable.

Description

technical field [0001] The invention belongs to the technical field of exterior protection of green energy-saving buildings, and in particular relates to a composite vacuum glass with double hollows with suspended films. Background technique [0002] With the promotion and wide application of passive house concepts and standards in green and energy-saving buildings, higher requirements are put forward for the glass used in the outer enclosure. The overall U value of energy-saving windows is required to be lower than 0.8w / m 2 .k or less. Ordinary insulating glass units cannot meet the requirements at all, and double insulating glass units made of triple-layer glass can only barely meet the requirements by filling expensive inert gases such as krypton. However, vacuum glass has excellent thermal insulation performance, and the U value can be reduced to 0.5w / m 2 .k or less, very suitable for the requirements of energy-saving windows for passive house enclosures. [0003] Al...
