Definitions

  • Wall-insulating glazing element and method for its production
  • the invention relates to a heat-insulating glazing element having the features of the preamble of claim 1, a method for its production, and uses of the glazing element.
  • ends of the evacuation tubes should not possibly end, in order to avoid damage during use, transport or installation.
  • they When attaching the evacuation openings on the front, they should preferably not protrude above the glass surfaces and in a lateral arrangement do not protrude beyond the nominal dimensions of the glass panes.
  • the evacuation tubes used in the conventional method have proven to be less practicable.
  • the pipe ends usually have to be protected by additional covers from mechanical damage and external corrosive influences. Not only does this affect aesthetics and design, it also creates additional production costs.
  • the evacuation opening must be opened on site and without destruction of the glazing in a simple manner and sealed vacuum-tight.
  • WO 2003/004430 describes a glass panel with an evacuation opening, which is arranged in the front region of a glass pane. To produce the opening, a stepped bore is first introduced into the glass pane, in then a glass tube is used. The vacuum tightness between the glass tube and the glass sheet is made on the glass surface by a solder glass. After evacuation of the gap, the end of the tube is fused by external heat.
  • the entire component In order for the vacuum-tight melting of the glass tube not the entire component must be placed in a complex vacuum chamber, but the evacuation and sealing can be done under normal air pressure conditions, a special evacuation device must be used.
  • the evacuation device is placed on the glass surface and sealed by vacuum seals against the glass surface so that a separate vacuum chamber is formed around the soldered glass tube. This chamber is then evacuated through a separate port so that the required vacuum can be made in the glass panel. After reaching the desired final pressure, the end of the evacuation tube is melted within the chamber.
  • a disadvantage of this method is that the pipe end protrudes at least a few millimeters above the glass surface and thus can be easily damaged by an external load. Therefore, the pipe must be protected by an additional cover with a diameter of about 10 mm to 15 mm. Just such a cover in the field of view of the component inevitably means an unacceptable impairment of the aesthetics of the glazing element.

  • a separate vacuum chamber is made around the opening to be closed in this process by placing an evacuation device on the glass surface.
  • the ball is then softened at a temperature of 450 0 C and thus closed the opening. So that the ball material does not protrude beyond the glass surface after softening, the surface of the glass pane must additionally be provided by mechanical chamfering with a cavity of a defined geometry into which the ball material can flow.
  • WO 91/02878 describes a method in which an evacuation means is arranged in the periphery of the vacuum insulating glass in such a way that the melted tube stump, which consists of the material glass, essentially does not protrude beyond the nominal glass dimensions. In these vacuum insulating glass is only a small distance of the two glass panes of about 0.1 mm before.
  • the use of the proposed evacuating means requires that the vacuum insulating glass either contain special channels directly in the glass surface, or glass panes with at least one corner removed, or panes of glass with specially prepared edges.
  • the proposed technique is therefore very complex and prone to failure. Additional measures to protect against mechanical damage are required.
