Definitions

  • the present invention relates to a spacer profile made of an elastically-plastically deformable, poorly heat-conducting material for a spacer frame, which is to be attached in the edge region of at least two spaced apart panes, in particular transparent panes for insulating pane units, to form a pane spacing, the spacer profile comprising a chamber, which has in one of its walls a plastically deformable ner reinforcing element which extends in the longitudinal direction of the profile, and the spacer profile has a diffusion-proof layer which extends essentially over its entire width and length.
  • elastically-plastically deformable materials mean those materials in which elastic restoring forces are effective after the bending process, as is typically the case with plastics, part of the bending taking place via plastic, non-reversible deformation.
  • Plastically deformable materials include those materials in which practically no elastic restoring forces act after the deformation, as is typically the case when bending metals beyond the yield point.
  • Poorly heat-conducting or heat-insulating materials should be understood to mean those materials which, compared to metals, have a significantly lower, ie at least a factor of 10, lower thermal conductivity.
  • the thermal conductivity values are typically of the order of magnitude ⁇ 5 W / (mK) and below, preferably they are less than 1 W / (mK) and more preferably less than 0.3 W / (mK).
  • the panes of the insulating pane unit are normally glass panes made of inorganic or organic glass within the scope of the invention, but the invention is not restricted to this.
  • the panes can be coated or refined in some other way to give the insulating pane unit special functions, such as increased thermal insulation or soundproofing.
  • spacer frames The most important task of spacer frames is to keep panes of a pane unit at a distance, to ensure the mechanical strength of the unit and to protect the space between the panes from external influences.
  • insulating pane units with high thermal insulation it should be noted that the heat transfer characteristics of the edge bond and thus of the spacer profile from which the spacer frame is made require special attention.
  • plastic spacer profiles have also been used for a long time to take advantage of the low thermal conductivity of these materials.
  • materials of this type generally have a low diffusion tightness in comparison with metals.
  • filler gases such as argon, krypton, xenon and sulfur hexafluoride, with which the space between the panes is filled, must be kept within minimal limits
  • Use of plastic profiles usually requires special measures. For this reason z. B. proposed in DE 33 02 659 AI to provide a spacer profile with a vapor barrier by applying a metal foil or a metallized plastic film to the plastic profile.
  • Plastic profiles also have the disadvantage that they can be bent only with great effort or not at all to produce one-piece spacer frames.
  • plastic profiles become straight rods in the dimensions of each Cut the unit of appropriate dimensions and connect it to a spacer frame using several corner connectors.
  • the profile should be cold-bendable with conventional, if necessary slightly modified, conventional bending systems, that is to say it should be bendable with little or no heating so that disruptive deformations do not occur.
  • the reinforcing elements are embedded in the side walls of the spacer profile made of poorly heat-conducting material or are arranged on their surfaces and thus no direct thermal contact between the panes is produced by them, the heat conduction from one pane to the other is achieved by the spacer profile the reinforcing elements are influenced only to an extremely small extent.
  • the reinforcing elements are influenced only to an extremely small extent.
  • the arrangement of the reinforcing elements according to the invention ensures that when selecting the main volume fraction of the profile, the elastically-plastically deformable, poorly heat-conducting material, its plastic deformability is not in the foreground, but also almost completely elastic materials can be used if these are concerned of thermal insulation.
  • the reinforcement elements can be selected specifically with regard to their plastic deformability and their properties during the bending process, without their dimensions or their material being subject to significant restrictions with regard to the level of their thermal conductivity.
  • the material and the thickness of the diffusion-tight layer can only be selected with regard to their diffusion-tightness, without the diffusion-tight layer having to contribute to the deformability of the profile.
  • comparatively thin, diffusion-tight layers can be used within the scope of the invention, which is advantageous for cost reasons and for reducing the heat conduction through the profile. It is within the scope of the invention to dispense with a separate diffusion-proof layer if the material of the profile itself is already sufficiently diffusion-proof.
  • the profile according to the invention is designed as a hollow chamber profile, the chamber normally being filled with hygroscopic material and water-vapor-permeable regions, for example perforations, in the inner wall of the chamber facing the window space allowing steam or moisture to be exchanged between the window space and the chamber. This keeps the moisture content in the space between the panes low in order to avoid condensation at low temperatures.
  • the spacer profile can also have a U-shaped cross section which is open towards the space between the panes, if care is taken to ensure that the desiccant is firmly anchored in the chamber, for example by means of adhesion.
  • the cross section of the reinforcing elements can be designed in a variety of ways. So these elements z. B. be formed as wires, which enables simple and therefore inexpensive manufacture.
  • the reinforcing elements can also be designed as flat or angle profiles. This ensures a particularly high dimensional stability, especially in the cross-sectional corner areas, of the spacer profile.
  • a combination of wires and flat or angle profiles in a spacer profile is also possible.
  • the reinforcing elements generally consist of metal or a metal alloy, preferably aluminum or an aluminum alloy. This results in a particularly high plastic deformability of the spacer profile and a particularly low springback after bending
  • the diameter of the wires is preferably less than 3 mm, in particular about 1 mm, while the flat or angle profiles generally have a thickness of less than 3 mm, preferably a thickness of less than 1 mm.
  • Such a choice of the diameter of the wires or the thickness of the profiles ensures good plastic deformability with low material costs and low weight of the spacer profile.
  • the reinforcing elements are preferably arranged in cross-sectional corner regions of the spacer profile. These areas are very sensitive since they are particularly stressed by stretching or compression during the bending process, and damage occurs particularly at these points in conventional profiles during the bending process.
  • the arrangement of the reinforcing elements according to the invention in these areas prevents such damage from occurring.
  • reinforcing elements in the form of wires or angle profiles are arranged at least in the region of both ends of the two side walls, the bending resistance moment of the spacer profile advantageously increases thereby, so that particularly good cold bendability is achieved.
  • flat or angular profiles extend essentially over the entire height of the side walls of the spacer profile. The resulting high bending resistance moment gives the side walls a particularly high level of dimensional stability, so that the occurrence of disruptive deformations is reliably avoided.
  • angle profiles are provided in cross-sectional corner areas of the spacer profile, the cross-sectional shape of the angle profiles essentially corresponding to the cross-section of these corner areas, so that good protection of the spacer profile during the bending process and general handling and high dimensional stability is achieved .
  • reinforcing elements made of different materials within a profile.
  • Reinforcing elements made of composite materials can also be provided.
  • the reinforcing elements can have different materials or different thicknesses in their longitudinal direction or also over their cross section.
  • the plastic can contain conventional fillers, additives, dyes, UV protection agents, etc.
  • the diffusion-tight layer if present as a separate component, preferably consists of a material with a thermal conductivity ⁇ ⁇ 50 W / (mK). Metals have proven to be preferred materials for the diffusion-tight layer, in particular tinplate or also stainless steel.
  • the diffusion-tight layer can also consist of a plastic, such as a fluoropolymer, polyvinylidene chloride or ethyl vinyl acetate.
  • the diffusion-tight layer can be applied by physical or chemical coating processes, such as sputtering or plasma polymerization. However, it is preferably connected to the profile in a film-like manner. Here means “cohesively the "the permanent connection of the two components of the composite, for example by lamination, if necessary via an adhesion promoter, by embedding or similar techniques.
  • the diffusion-tight layer is arranged at least in the region of the outer wall of the chamber of the spacer profile, preferably also in the region of the side walls.
  • the diffusion-tight layer is preferably applied to the outside of the outer wall and, if appropriate, to the side walls of the chamber. But it can also be arranged on the inside or embedded in the walls. As a result, the bending process can be further simplified depending on the bending system, since direct contact of the mechanically sensitive diffusion-tight layer with force-exerting elements of the bending system can be avoided in this way. This also ensures permanent protection of the diffusion-tight layer.
  • the diffusion-tight layer can additionally be provided with a protective layer in order, for. B. largely avoid aging processes or radiation influences or damage caused by mechanical stresses.
  • the spacer profile is preferably glued to the inside of the panes with a butyl sealant based on polyisobutylene.
