One ebbs and another, especially the requirement of energy saving is an important factor to be considered. The requirements for K value in national standards are becoming more and more stringent (K value is the reciprocal of the thermal resistance R ₀ of the material), and single-layer glass has been unable to meet the requirements of national standards. The K value required in the standard, so double-glazed windows and triple-glazed windows have appeared. The K value currently achievable by double-glazed windows is generally in the national standard GB/T8484-2002 in the building exterior window insulation performance classification table The K value of the triple-glazed outer window can reach 5-7 (that is, the K value is 3.5-2.5). The existing triple-glazed outer window structure is generally triple-glazed with equal thickness, etc. The distance is juxtaposed and combined with the window frame after being fixed. The thickness of the general glass is 5-6mm, and the distance between adjacent glasses is 6-7mm. With the sash frame, the weight of the window is quite large.

Description of drawings:

Fig. 1 is a structural schematic diagram of an embodiment of the present utility model.

Detailed ways:

Please refer to Fig. 1, the specific embodiment of the present utility model is as follows: comprise outer layer glass 1, middle glass 2 and inner layer glass 3, also comprise outer air layer 4, inner air layer 5 and the strengthened outer seal of the end of three layers of glass Edge 9, the inner and outer layers of glass (3, 1) described here are defined for the annotations in the corresponding drawings, not to limit the outer layer of glass 1 to only be used outside the window (room) and to limit the inner layer of glass 3 It can only be used in the window (chamber). The outer air layer 4 refers to the air layer between the outer glass 1 and the middle glass 2, and the inner air layer 5 refers to the air layer between the inner glass 3 and the middle glass 2. The air layer, the key is that the three layers of glass are set with different thicknesses, and there is a sealant 6 between the ends of adjacent glass layers; the strengthened outer edge 9 refers to the material thickness or structure of the outer edge 9 It needs to be thickened or strengthened to resist large external wind pressure or deformation of its own weight. The above-mentioned unequal thickness setting means that at least two layers of glass in the three-layer glass have different thicknesses. The air layer, the window sashes with three layers of glass should have five layers and isolate the indoor and outdoor spaces. The density difference between glass and air is huge, and the thermal conductivity is also different. Glass has reflective properties, and the interface between glass and air is a The interface with a huge difference in density, for sound waves, this interface will produce quite complex physical phenomena of reflection and incidence, and there is an energy conversion between sound waves and heat, and the thickness of different air layers will make the temperature of different air layers Different, for example, the temperature of the air layer close to the high-temperature end in the environment can be made a little higher, which can increase the thermal resistance of the entire triple-layer glass (correspondingly reduce the K value). The propagation of relative heat waves will also produce quite complex physical phenomena. Due to the existence and temperature difference of indoor and outdoor temperature differences, the combination of the above-mentioned glass with different thicknesses and different air layers produces much higher than that of the prior art. The technical effect of thermal insulation and sound insulation of the traditional three-layer glass structure with thick glass and the same air interval has been confirmed by many tests by authoritative organizations.

The outer air layer 4 and the inner air layer 5 between the three layers of glass can be the same thickness, such as 5mm or 6mm, and the combination of glass with different thickness can reduce the K value, the smaller the K value, the higher the calorific value. The bigger, the better the heat insulation and sound insulation effect, the above-mentioned outer air layer 4 and inner air layer 5 can be of different thicknesses, such as the outer air layer 4 is 5mm and the inner air layer 5 is 6mm, or vice versa or other options, with different thicknesses The combination of glass can not only reduce the K value, but also combine a variety of glass-air layers with better arrangement and combination settings to adapt to climate conditions in different regions, such as different latitudes, altitudes or temperature differences; Above-mentioned outer layer glass 1 and inner layer glass 3 are equal thickness, and the thickness of intermediate glass 2 is less than inner and outer layer glass (3,1), and the thickness of preferred outer layer glass 1 is 4mm, and the thickness of intermediate glass 2 is 3mm, inner layer The thickness of the glass 3 is 4mm, and the total thickness of the three-layer glass is 11mm, which is only about 10% more than the total thickness of the traditional two-layer glass of 5mm, but the thermal insulation performance is improved by 2 to 3 K value grades, Compared with the traditional three-layer 5mm glass, the total thickness is greatly reduced, but the thermal insulation performance can still be improved by more than 1 K value level. In the above-mentioned three-layer glass, the thickness of the outer air layer 4 is set to be greater than or smaller than the inner The thickness of the air layer 5 can better provide optimized options.

The thickness of the described triple-layer glass is gradually reduced from outside to inside, and the thickness of its preferred outer glass 1 is 5mm, the thickness of the middle glass 2 is 4mm, and the thickness of the inner glass 3 is 3mm; K value, the outer layer of glass 1 faces the outside and maintains a strong requirement for outdoor wind pressure, and the total weight of the glass is greatly reduced compared with the total weight of the traditional three-layer glass; in the above cases, the The thickness of the outer air layer 4 is greater than the thickness of the inner air layer 5, or the thickness of the outer air layer 4 is smaller than the thickness of the inner air layer 5, the K value can be further reduced, and the selectivity of specific settings can be appropriately increased, such as the outer air Layer 4 is 5mm or 6mm or vice versa or other options.

The two ends of the intermediate glass 2 are shorter than the inner and outer glass (3, 1), the outer end surface 8 of the sealant 6 is basically flush with the end surface of the intermediate glass 2, and a gap is formed between the inner and outer glass 3, 1 and the outer edge 9. Sealed cavity 7; the window sash is a main transmission channel of heat inside and outside the building, the frame of the window sash is generally an aluminum alloy frame, and the thermal conductivity of aluminum alloy is quite high, so the heat lost by the frame is measured as a percentage of the heat lost by the window sash Thirty or so, the existence of the above-mentioned cavity 7 makes the heat conduction channel of the outer sealing edge 9 be cut off from the side wall, and the heat dissipation channels of the parallel front and rear sides of the outer sealing edge 9 are cut off by the cavity 7, which can further reduce the K value. An elastic seal is arranged between the inner and outer glass (3, 1) and the outer sealing edge 9, which can further reduce the K value.
