Telescopic spacing bar, telescopic hollow glass and manufacturing method of telescopic hollow glass

Abstract

The invention provides a telescopic spacing bar which is at least composed of two parts, a convex edge, a groove or a convex edge which are matched with each other are arranged between every two adjacent parts, and one part of the convex edge can be embedded into the groove of the other part or between the convex edges to form a telescopic structure. The invention further provides telescopic hollow glass, the number of the glass is two, and a closed hollow layer is formed between the two pieces of glass and the telescopic spacing bar. The outer side edge of the hollow layer is integrally sealed through a sealing tape or a sealing adhesive tape, and the sealing tape or the sealing adhesive tape forms a certain expansion amount through corrugation and can adapt to the breathing action of the hollow glass so as to synchronously stretch out and draw back with the telescopic spacing bar. The heat conduction performance of the spacing bar can be greatly reduced, the heat insulation and heat preservation performance of the hollow glass is further improved, especially the flatness of the surface of the glass is improved, the mirror surface effect is kept, and the service life of the hollow glass can be greatly prolonged.

Description

technical field [0001] The invention relates to the field of glass deep processing, in particular to a telescopic spacer, a telescopic hollow glass and a manufacturing method thereof. Background technique [0002] Energy conservation and environmental protection is one of the most important topics of current research. At present, the energy consumption of buildings accounts for more than 30% of the total energy consumption of society, and the energy consumption of doors and windows accounts for about 50% of building energy consumption. Improving the thermal insulation performance of doors and windows is The main way to promote energy saving in buildings; insulating glass is a building energy-saving product with good heat insulation and sound insulation properties. At present, the application of insulating glass is very common. During use, when there is a temperature difference between the inner and outer surfaces of the insulating glass, the heat transfer between the middle ...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides a telescopic spacer, which not only has a simple structure and is easy to manufacture, but also can greatly reduce its thermal conductivity, solve the problem of cold bridges at the edge of the insulating glass, and further improve the heat insulation of the insulating glass. Insulation performance; the present invention also provides a telescopic insulating glass, which can adapt to the breathing phenomenon of the insulating glass, and will not generate stress and deformation of the glass at the edge seal, prevent cracking and gaps at the sealing part, and affect the mirror effect of the insulating glass , greatly improving the aesthetics and service life of insulating glass
