Definitions

  • the invention relates to a spacer with an adapter element for connecting a pane to the spacer having a fastening groove, insulating glazing with an adapter element, and a method for producing the insulating glazing with an adapter element and a use of the insulating glazing.
  • the insulating effect of glazing on buildings is a decisive factor, especially with regard to lower carbon dioxide emissions. But the protective effect of glazing also plays a crucial role in the construction of new buildings.
  • the DIN EN 356 standard regulates the testing of burglar-resistant glazing. It describes methods for testing for throw-through resistance and penetration resistance. For the higher classes, the penetration resistance test is based on standardized hammer and ax blows, whereby the effort required to open the glazing is determined. Breakthrough resistance is divided into three test classes P6B to P8B, with P6B corresponding to more than 30 hammer and ax blows, P7B to more than 50 hammer and ax blows and P8B to more than 70 hammer and ax blows.
  • US4243719A , DE 3486336 T2 and DE 102008043718 A1 disclose plastic-glass laminates of glass and polycarbonate or polymethyl methacrylate.
  • the panes are connected to each other over a large area using cast resins or laminating films.
  • the pane arrangement is preferably laminated in an autoclave process, with a thermoplastic polyurethane film generally being used for lamination between polymer panes and adjacent glass panes.
  • a thermoplastic polyurethane film generally being used for lamination between polymer panes and adjacent glass panes.
  • the production process is expensive due to the large number of steps required, such as drying the polymeric panes or the autoclave process.
  • raw material costs for thermoplastic polyurethane films are high.
  • the insulating effect of the laminate is low compared to the relevant insulating glazing.
  • EP 2 733 295 A1 discloses an insulating glazing comprising a first glass pane, a second glass pane and between them a shatterproof thermoplastic pane.
  • the thermoplastic disk is supported by a U-shaped receiving groove Surrounded receiving element, wherein the receiving element is bonded via a respective spacer with the first glass pane and the second glass pane.
  • U.S. 2009/139165 A1 , WO 2011/152569 A1 , WO 2016/091646 A1 and CH 329280 A each show an insulating glass pane with a spacer and an adapter element.
  • the object of the present invention is achieved according to the invention by a spacer with an adapter element for connecting a pane with the spacer having a fastening groove according to independent claim 1, insulating glazing with the adapter element according to claim 7, a method for producing the insulating glazing with the adapter element according to claim 13 and their use according to claim 14.
  • Preferred embodiments of the invention emerge from the dependent claims.
  • the adapter element for connecting a pane to a spacer having a fastening groove comprises at least one receiving profile for fastening to the pane and a lower part for fixing the adapter element to the spacer.
  • the lower part of the adapter element is formed in a form-fitting manner with the fastening groove of the spacer.
  • the fastening groove forms a depression running in the longitudinal direction of the spacer.
  • the cross-sectional shape of the base is designed to match the mounting groove.
  • the receiving profile connects to the lower part of the adapter element, with the receiving profile protruding completely out of the fastening groove when installed.
  • the receiving profile is U-shaped and comprises two side legs which are intended to rest at least partially on opposite surfaces of the pane in the peripheral edge region.
  • the receiving profile has a bottom surface which is intended to encompass a peripheral edge of the pane and thus to fix the pane. Lateral fixation of the pane is ensured by the side legs of the adapter element, with the side legs and the bottom surface of the receiving profile not necessarily contacting the pane but only limiting the position of the pane.
  • Such an adapter element simplifies the otherwise very complex Manufacturing process for insulating glazing with a break-through-resistant effect, since a standardized spacer can be used for all break-through classes.
  • a protection class of P6B, P7B or P8B is achieved.
  • the lower part of the adapter element has a trapezoidal shape.
  • the adapter element can thus enter into a so-called dovetail connection with the spacer. This increases the stability of the connection.
  • the adapter element is advantageously designed in one piece. This is particularly advantageous with regard to the mechanical stability of the adapter element and simple and inexpensive assembly.
  • the receiving profile of the adapter element is U-shaped.
  • the material thickness of the receiving profile is preferably 0.5 mm to 5 mm, particularly preferably 1 mm to 3 mm. In practice, the latter area in particular has proven to be a good compromise between sufficient stability and the lowest possible thermal conductivity.
  • the mounting profile optionally contains an insert that prevents the third pane from slipping and the resulting noise when opening and closing the window.
  • the mounting profile can be wider than the pane mounted in it, so that the insert mentioned can also be inserted into the mounting profile.
  • the insert helps to compensate for the thermal expansion of the third pane when it heats up, so that stress-free fixing is guaranteed regardless of the climatic conditions.
  • the insert can also only be attached in partial areas of the receiving profile, for example an empty space lying between the bottom surface and/or the legs and the peripheral edge of the third pane. In this case, only the possible empty spaces within the receiving profile are completely or partially filled by the insert.
  • the side legs are stepped and/or have a structure similar to a fir tree on their surface facing the pane.
  • the stepped side legs of the receiving profile are stepped in such a way that the pane to be inserted into the receiving profile can be fitted into one of the steps. Because the recording profile through has different widths due to the step-like course of the side legs, the adapter element does not have to be adjusted again when the pane thickness is changed. This is particularly advantageous for simplifying the production process, since a standardized spacer can be used for all penetration classes, regardless of the thickness of the panes used.
  • the adapter element preferably contains polyethylene (PE), polycarbonate (PC), polypropylene (PP), polystyrene, polybutadiene, polynitrile, polyester, polyurethane, polymethylmetacrylate, polyacrylate, polyamide, polyethylene terephthalate (PET), polybutylene terephthalate (PBT), preferably acrylonitrile-butadiene Styrene (ABS), acrylester-styrene-acrylonitrile (ASA), acrylonitrile-butadiene-styrene/polycarbonate (ABS/PC), styrene-acrylonitrile (SAN), PET/PC, PBT/PC and/or copolymers or mixtures thereof.
  • the adapter element can also be reinforced with glass fibers.
  • the adapter element can contain a metallic material.
  • the mechanical strength of metallic materials is usually higher than that of other materials. Furthermore, metallic materials do not tend to splinter fracture when subjected to force. Examples of suitable materials for producing the receiving profile are aluminium, iron, steel, stainless steel and/or mixtures and/or alloys thereof.
  • the receiving profile is formed in one piece from aluminum or aluminum alloys.
  • Aluminum or aluminum alloys have the advantage that they have high specific strength with low weight. Accordingly, when using these materials, a high level of edge strength and burglary protection can be achieved without significantly increasing the weight of the insulating glazing.
