Definitions
- the invention relates to a heat-insulating glazing element with the features of the preamble of claim 1, and method for its production. Also, uses of the glazing element are described.
- vacuum insulating glass with at least two glass plates, which include an evacuated gap and are connected to each other via defined spacers and a peripheral RandaMichtungs noticed.
- the spacers are distributed between the glass plates over their surface, z. B. with a uniform dot matrix with a distance from each other from 20 mm to approx. 50 mm or above.
- the generation of the vacuum in the intermediate space can be effected by evacuation devices mounted in one of the glass plates and / or at the edge seal and / or in a vacuum chamber.
- a glazing element is described with a glass plate arrangement whose Randabdich- timgs spur comprises a profiled frame which is vacuum-tightly secured to inner sides of outer glass plates of the glass plate arrangement.
- the task of the vacuum is to prevent heat losses through convection and heat conduction of the gas between the glass plates. It is the decisive factor for achieving high thermal insulation values with vacuum insulating glass. Therefore, high demands are placed on the quality of the vacuum (achievable pressure), its maintenance and improvement (vacuum-tightness and gettering) as well as on the methods for providing the evacuation device and the edge sealing device.
- the edge seal has a special meaning, because by this not only vacuum tightness is ensured, but also the occurring during use of the component mechanical and thermo-mechanical stresses and the forced deformations z. B. due to the thermal expansions without loss of function least partially absorbed or compensated. In conventional techniques, such distortions acting in all spatial directions have not yet been taken into account or are not sufficiently taken into account. Loads arise in particular by the combination of the external air pressure and the different thermal expansion of the individual glass plates against each other. The latter is due to the fact that the individual glass plates occupy different temperatures depending on their intended use. In the case of glazing, for example in buildings, the inner glass plate usually has an almost constant temperature, while the outer glass plate, on the other hand, can have a significantly higher or significantly lower temperature.
- the vacuum insulating glazings in the corner areas where thermal expansion phenomena occurring in all directions overlap locally, and because of the associated mechanical stresses can even lead to distortions or the like, have a particularly high susceptibility.
- damage or damage to conventional vacuum glazing elements in the form of cracks and flaking in the entire edge area in case of improper use of ductile or glassy adhesive or bonding materials can be determined.
- distortions along the edges of the glass are also observed. For example, in local shadowing, local cooling or the like.
- Such locally variable or locally acting load or force components must also be able to be compensated or compensated by a functional edge seal.
- a first disadvantage of the known vacuum insulating glazings is that only very small volumes, which are formed between the glass plates, are available for the evacuation. For typical distances of the glass plates of z. B. about 50 ⁇ ⁇ ⁇ to 300 ⁇ arise for the volumes values of only about 0.05 1 to 0.3 1 per square meter.
- the inner surface is very large at the glass surfaces oriented towards the evacuated intermediate spaces, so that the known vacuum insulating glazings have extremely low volume-surface ratios of less than 0.5 mm (typically between about 0.025 mm and 0.15 mm) mm) are equipped.
- These particularly unfavorable conditions mean that the residual gas molecules adsorbed or bound to the inner surfaces, in the near-surface regions or the spacers even in very small concentrations (eg water, hydrocarbons, etc.) or other contaminations due to, for example, As desorption or diffusion processes or the like are released and thus lead to an undesirable increase in pressure in the evacuated spaces.
- a second disadvantage of conventional vacuum insulating glazings is that in order to provide the required vacuum below 10 " 1 Pa to 10 " 3 Pa or below, extremely long evacuation times in the range of several minutes to sometimes several hours are required, so that the production of the Components is very expensive and sometimes even a high technical and financial cost for the evacuation system is required.
- evacuation there is a transition from the viscous gas flow at high pressures to the molecular flow at low pressures. Molecular flow sets in when the mean free path of molecule-molecule collisions is approximately equal to the distance of the glass plates.
- the evacuation time depends on the cross-sectional dimensions of the spaces to be evacuated between the glass plates. Due to the small distances of the glass plates (low conductance), the gas molecules take a very long time, mainly to pass through the shocks with the glass surfaces to and finally through the evacuation device, and then pumped by a vacuum pump. Another aspect is that the actual evacuation is usually carried out locally either by an evacuation tube attached to the edge of the glazing unit or by an evacuation tube attached to one of the glass plate surfaces.
- the evacuation pipes can only be fitted with conventional vacuum insulating glazings for design reasons. diameter of typically from about 1mm to about 2mm.
- a third disadvantage of conventional vacuum insulating glazings is the fact that the very small volumes between the glass plates do not provide sufficient space to accommodate a sufficient amount of getter materials.
- the getter materials can be activated by, for example, thermal evaporation, without the vaporized materials being visibly obscured by the user, ultimately compromising the quality of the glazing elements equals.
- a critical area is also the corner regions of the conventional glazing elements, where the length or shape changes acting in different spatial directions are superimposed in a complex manner and the mechanical stresses occurring there assume particularly high values. In practice, cracks, chipping, material fatigue and even glass breakage are found in conventional glazing elements.
- the object of the invention is to provide an improved glazing element with which disadvantages of conventional glazing elements can be avoided.
- the glazing element should be characterized in particular by a high mechanical stability, a simple structure and a simplified production.
- the object of the invention is, in particular, to provide a glazing element with dimensions of up to 2,500 mm edge length and above in freely selectable geometries (shape, size) such that a high vacuum can be maintained in the glazing element over the entire product service life.
- the object of the invention is also to provide an improved method for producing a glazing element, with which disadvantages of conventional techniques for the production of glazing elements can be avoided.
- a glazing element which comprises a glass plate arrangement with at least two glass plates, of which a first outer glass plate projects beyond a second outer glass plate on all sides around a protruding surface.
- the glazing element further comprises spacer means having spacers adapted to adjust a distance between the glass plates.
- the spacers form a space between the glass plates in which a pressure reduced from an external atmospheric pressure is formed.
- the glazing element further comprises an edge sealing device arranged to seal the gap between the glass plates from the environment.
- the edge sealing device comprises a profiled frame which is vacuum-tightly vacuum-tightly attached to the overhang surface of the inner side of the first outer glass plate and to an outer side of the second outer glass plate and forms an evacuation space connected to the intermediate space at the lateral edge of the second outer glass plate.
- the edge sealing device is formed by a profiled frame of a sheet-like or foil-shaped, multi-curved, dimensionally stable material.
- the frame comprises fixing regions (connecting regions) on which the frame is connected in a planar manner to the glass plates, and profile surfaces which extend between the fixing regions.
- the fixing regions comprise two substantially planar and mutually parallel regions, which are rigidly formed by their connection to the glass plates. With a deformation of the glass plates (for example due to thermal expansion), no or only slight deformations of the fixing regions may occur so that no critical peeling forces occur perpendicular to the surfaces of the glass plates.
- the profile surfaces which form the transition from a first of the fixing regions on the first glass plate to the second fixing region, are mechanically deformable.
- the profile surfaces may be piecewise flat or curved. Parts of the profile surfaces that are more curved than their surroundings are called arc sections.
- the frame In the arch areas, the frame has a radius of curvature of at least 0.5 mm, preferably at least 1 mm.
- the frame forms a multiply curled winding or arched leaf that extends along the edges of the glass plates.
- the frame has the shape of a bellows, the folds are not kinked, but bent and formed by the arcuate areas.
- the profiling of the frame is formed by the choice of material and its thickness so that under the influence of the external air pressure, the shape of the profile surfaces including the arcuate areas is not or negligibly changed little. This represents a significant advantage over the foil provided in the conventional glazing element, in which strong deformations would occur due to the air pressure forces, so that the material would not withstand the forces occurring during the deformation of the glass plates.
- the dimensionally stable frame of the glazing element according to the invention by the connection with the inside of the larger glass plate and the outside of the smaller glass plate is suitable both to firmly connect the glass plates with each other, and to tolerate any deformations due to movements or changes in size of the glass plates, without the Vacuum-tight connection with the glass plates to interrupt.
- the evacuation space connected to the gap is compared to a conventional glazing element, e.g. B. increased according to EP 247 098, so that advantages for the evacuation of the glazing element and for the absorption of thermal movements of the glass plates are achieved relative to each other.
- the evacuation space is also increased by the multiple arc shape in the profile of the frame compared to a conventional glazing element, whereby advantageously an additional evacuable buffer and / or functional space is created.
- the above object is achieved by a device comprising at least one glazing element according to the above first aspect.
- the device is z.
- the construction element has an outside, which is intended to point in the installed state of the device in an external environment, and an inside, which is intended, in the installed state of the device in the interior z.
- the largest outer glass plate of the glass plate assembly may be provided on the inside or outside of the device.
- the above object is achieved by methods of manufacturing a glazing element according to the above first aspect.
- the frame of the glazing element has a plurality of arc portions extending along the lateral edges of the glass plates.
- the arc regions can be bent in a direction parallel to the sur- face area, ie the profile of the edge sealing device is corrugated perpendicularly to the extent of the glass plates.
- advantages for the enlargement of the evacuation space may result from a large number of arc areas over the sur- face area.
- the arcuate regions can be bent in a direction perpendicular to the overhang surface, ie the profile of the edge sealing device is corrugated parallel to the extension of the glass plates. In this case, there may be advantages for the enlargement of the evacuation space due to increased profile areas over the overhang area.
- the profile surfaces of the frame are aligned almost perpendicular or nearly parallel to the projection surface.
- the arc portions when bent parallel to the projection surface, are shaped such that the arc portions facing the first outer glass plate are at least partially in mechanical contact with the inner surface thereof.
- the arch areas abut the supernatant surface on the inside of the first glass plate, thereby advantageously forming mechanical support points which stabilize the frame.
- the fixing areas are connected to the glass plates along sealing surfaces.
- the first sealing surface and the second sealing surface are flat and formed parallel to each other.
- the attachment of the first fixing region of the frame over the first sealing surface on the always (respectively) larger glass plate inwardly and the attachment of the second fixing of the frame on the second sealing surface on the always (respectively) smaller glass plate to the outside has the advantage that one side (surface) of the frame material is connected to both the first and second outer glass plates. The connection is made without a surface change, which improves the stability of the frame.
- the first sealing surface and the second sealing surface comprise a glass solder or at least partially contain this, at a temperature less than 600 ° C, in particular less than 540 ° C, softened.
- the fixing regions have a coefficient of thermal expansion which is adapted to the coefficients of thermal expansion of the glass plates and the frame, i. H. is chosen with minimal difference to these. It has proved to be particularly advantageous if the sealing surfaces contain at least one of the oxides of the elements lead, lithium, bismuth, sodium, boron, phosphorus and silicon.
- the frame of the edge sealing device is shaped and connected to the glass plates such that, in the evacuated state of the glazing element, the external atmospheric pressure acts on the first and second fixing regions of the frame.
- the fixing areas are pressed against the sealing surfaces and additionally stabilized.
- a further advantageous embodiment of the invention is characterized in that a vertical distance of an inner, pointing to the evacuation space edge of the first sealing surface of a next spacer is less than or equal to 70 mm, in particular less than or equal to 45 mm.

- the sealing material 610, 620 is affixed to the outer regions 601, 602, 621, 622, 631, 632 of the edge sealing device 600 and / or parallel to the surfaces of the glass plates 1, 2, 3 corresponding parts of the glass surfaces 1-2, 2-2 applied. It is crucial that the precise position and precise application of the sealing materials using z. B. dosing completely circulating and without any interruptions, openings or the like.
- the preferred sealing materials 610, 620 preferably comprise vitreous materials and / or low-emissivity glasses (eg, glass solders, glass frits, or the like) containing substances, preferably in the form of binder and / or solvent containing pastes, suspensions, foils, tapes or the like. Subsequently, the glass plates are sequentially deposited on the sealing material 610, 620, so that the stack shown in Figure 8C is obtained. The provision of the stack can in principle be done in reverse order by first the glass plates are placed on each other and then only the application of the framing takes place.
- vitreous materials and / or low-emissivity glasses eg, glass solders, glass frits, or the like
- substances preferably in the form of binder and / or solvent containing pastes, suspensions, foils, tapes or the like.
- the fourth method step comprises providing the mechanical connection between the evacuation tube / coupling element 710 and the vacuum system, and assembling the stack and thus providing the vacuum tightness in the sealing surfaces 6-1, 6-2.
- the joining is preferably carried out by melting the sealing material by means of heat treatment.
- the particularly uniform contact pressure required for a reliable sealing surface 6 - 1, 6 - 2 over the entire component dimensions is at least for the most part provided by the weight of the glass plates 1, 2, 3.
- the provision of the required vacuum conditions within the glazing element 10 preferably takes place by evacuation by means of a vacuum system under external atmospheric pressure conditions.
- the evacuation can preferably be started even during the assembly, and precisely at the time when the molten sealing material is not yet fully cured or solidified and can still be deformed by forces.
- This, provided by the negative pressure additional contact pressure is particularly advantageous because provided by the externally acting air pressure particularly uniform pressure forces and thus production-related tolerances, dimensional inaccuracies, etc., the melted sealing material can be even better compensated.
- the vacuum-tight closing of the evacuation tube 710 is carried out using the described methods.
- the vacuum conditions can be further improved. Assembly, evacuation and vacuum tight sealing can also be done under vacuum conditions.
- the manufacture of the heat-insulating glazing element 10 with which particularly good thermal insulation values (U values) of approximately 0.5 to approximately 0.3 W / (m K) and even below can be achieved, has been completed.
- the device not only includes the use of glass or the like as plate materials, which is a special case for transparent or semi-transparent devices. In principle, all materials can be used which can be produced in larger plate-shaped or curved or curved geometries, have sufficient mechanical strength and are suitable for vacuum.
