Definitions

  • the invention relates to a spacer frame for edge-glued insulating glass panes with the features specified in the preamble of claim 1.
  • a spacer frame for edge-glued insulating glass panes with the features specified in the preamble of claim 1.
  • two individual glass panes are put together with a spacer frame coated on both sides with an adhesive (usually a polyisobutylene).
  • the spacer frames are usually made of hollow profile bars, which mostly consist of aluminum or steel. It is known to produce the spacer frames by bending from a single hollow profile rod in such a way that the two ends of the hollow profile rod do not meet in the area of a corner, but in the area between two adjacent corners.
  • the frame is then closed by inserting a connecting element into the two hollow profile rod ends and pushing the two hollow profile rod ends together, forming a butt joint that is as tightly closed as possible.
  • the necessary anchoring of the connecting element in the end sections of the hollow profile rod can be achieved e.g. by gluing or - as shown by the Austrian patent application No. 7018/78, from which the preamble of claim 1 is derived - by clamping.
  • the spacer frames not only serve to keep two individual glass panes at a distance, they also fulfill a task for sealing and keeping the interior of an insulating glass pane dry.
  • the spacer frames are generally filled with a drying agent, for example molecular sieves or silica gel, which is connected to the interior of the insulating glass pane via small openings in the inner wall of the spacer frame.
  • the inner wall is understood here to mean that wall of the spacer frame which extends transversely to the two individual glass panes and delimits the interior space formed between them.
  • flanks of the spacer frame - these are the two profile walls parallel to the individual glass panes - carry the adhesive mentioned, by means of which the bond between the individual glass panes and the spacer frame is produced.
  • the adhesive applied to the flanks is not sufficient to seal the interior of the insulating glass pane from the outside in a moisture-tight manner.
  • the peripheral edge joint of the insulating glass pane is also filled with a sealing compound (usually a polysulfide such as Thiokol).
  • the edge joint is limited by the inner sides of the two glass panes and by the outer wall of the spacer frame; the outer wall is understood to mean the hollow profile wall opposite the inner wall.
  • the layer thickness of the sealing compound in the edge joint should not be less than a certain minimum thickness.
  • a hump could arise at the connection point of the spacer frame, where the two ends of the hollow profile rod meet, caused, for example, by elastic resilience of the profile material after the corner bending processes, which can also be caused by a tight fitting connector can not be fully absorbed.
  • This hump reduces the depth of the edge joint and thus the possible layer thickness of the sealing compound. This is particularly critical above the connection point of the spacer frame because there is a particularly high risk of moisture penetration due to the existing butt joint in the spacer frame.
  • the invention provides additional sealing depth in the edge joint of an insulating glass pane above the connection point of the spacer frame by opening the section of the butt joint in the outer wall of the spacer frame.
  • a sealing compound When filling the edge joint with a sealing compound, it can pass through the open butt joint and reach into the interior of the hollow spacer profile, whereby the claimed design and position of the connecting element ensures that at the connection point of the spacer frame under the outer wall, one of the open butt joint actually is available from open space.
  • This space can be provided in different ways.
  • a connecting element consisting predominantly of solid material
  • a recess can be provided in the center for this purpose.
  • an opening which is not too small can be provided in that wall which lies directly below the outer wall of the spacer frame.
  • An I-profile could also be used as a connecting element choose which is inserted into the ends of the spacer hollow profile such that the two parallel walls of the I-profile abut the flanks of the spacer frame.
  • a solid connecting element which is sufficiently rigid on the one hand and closes the ends of the spacer hollow profile with its cross section, and on the other hand easily allows the molding of limited recesses in the area of the later butt joint of the spacer frame (claim 3).
  • a design of the connecting element with a U-shaped cross-sectional shape is also suitable, at least in the central region, which lies under the butt joint of the spacer frame (claim 4), in particular a design as a U-profile, which is closed at the ends by a raised tab (claim 5) .
  • Such a connecting element produced as a U-profile can be produced very inexpensively with a combined stamping and bending tool made of sheet metal; However, when choosing the material for fasteners, you are by no means limited to metal, you can also use plastics.
  • the above-mentioned U-profile should be inserted with its back (including the middle profile wall that connects the two outer, parallel side parts of the U-profile) into the still open spacer frame so that this back lies against the inner wall of the spacer frame, so that the open side of the connecting element faces the outside of the spacer frame.
  • a solid connecting element is best anchored by clamping it in the spacer hollow profile.
  • tabs are expediently cut out of the profile back, which with their free ends face the insertion direction and do not oppose the insertion movement, but an attempt to pull the connecting element out of the hollow spacer profile again, because the one pointing in the pulling direction Claw clings to the hollow profile wall.
  • These tabs can advantageously be formed by a suitably designed, combined punching and bending tool in one and the same operation as the other parts of the connecting element.
  • These lateral troughs are preferably filled with an adhesive and sealing compound before the spacer frames are installed in an insulating glass pane, in particular with a polyisobutylene or similar material which is used in any case for coating the two flanks of the spacer frames before they are installed in an insulating glass pane .
  • This measure significantly improves the tightness of an insulating glass pane in the area of the butt joint of the spacer frame.
  • the free space in the connecting element under the butt joint of the spacer frame is as wide as possible (claim 8), that is, it should extend as far as possible to the side parts of the connecting element which are still necessary for reasons of stability .
  • the opening of the butt joint in the outer wall of the spacer frame between the flanks of the spacer frame should also be as large as possible.
  • the outer wall of a typical spacer hollow profile usually runs parallel to the profile back in a central region, whereas the edge regions the outer wall are bevelled. With such a profile shape, the opening of the butt joint should extend at least over the entire width of the central region of the outer wall (claim 9).
  • the butt joint can be opened in various ways, e.g. you could provide a corresponding cutout in the outer wall at the two ends of the hollow profile rod.
  • the opening of the butt joint is simply effected by - after inserting the connecting element - bending the outer wall of the spacer frame inwards on both sides of the butt joint, so that the edge of the outer wall of the spacer frame is then directed obliquely towards the inner wall of the spacer frame (claim 10).
  • This can be achieved in only one work step by means of a pressure stamp and has the further advantage that an additional anchoring of the connecting element is possible.
  • the spacer frame shown in FIG. 1 is bent from a hollow profile bar and closed at a connection point 1 between two corners 2 and 3 by a connecting element 4 inserted into the two ends 5, 6 of the hollow profile bar.
  • the cross-sectional shape of the hollow profile can be seen from FIGS. 4 and 6:
  • the hollow profile has an inner wall 7 which extends at right angles to the individual panes 8 and 9 of an insulating glass pane, two flanks 10 and 11 parallel to the individual panes 8 and 9, and an outer wall 12 which runs parallel to the inner wall 7, but is narrower than this and is connected to the flanks 10 and 11 via inclined surfaces 13 and 14.
  • the connecting element 4 has a cross-sectionally U-shaped basic shape and is dimensioned and inserted into the hollow profile rod at both ends so that the back 17 of the inner wall 7 of the spacer frame rests, whereas the side parts 18 and 19 abut the flanks 10 and 11 of the spacer frame and up to reach shoulders 15 and 16.
  • the ends of the back 17 protrude beyond the side parts 18 and 19 and are bent in the direction of the outer wall 12 to form tabs 20 and 21, which largely close the cross section of the spacer frame profile and thereby prevent the filled-in drying agent from trickling out the back 7 tabs 22 and 23 cut out and raised, which are directed with their free sharp ends 24 and 25 of the direction of insertion and resist pulling out of the connecting element 4 in that they claw with their ends 24 and 25 in the outer wall 12 .
  • a bead 26 is provided to limit the insertion depth.
  • the outer wall 12 After inserting the connecting element 4 into the two ends 5 and 6 of the spacer frame profile, the outer wall 12 becomes the joint on both sides joint 27 bent inward, for example by means of a pressure stamp, whereby the butt joint 27 at the same time spreads in the area of the outer wall 12.
  • the sealing compound 28 can penetrate through the opened butt joint 27 into the interior of the spacer frame and much more sealing compound can be applied and securely anchored to the critical joint than in the prior art was possible.
  • Methods for regulating the quantity of the sealant when applying the sealant are state of the art. So it is e.g. It is possible to arrange a measuring device in front of the nozzle from which the sealing compound emerges, which continuously measures the depth of the edge joint and controls the supply of the sealing compound according to the measurement.
  • the connecting element 4 ' is a solid profile bar, the cross-sectional shape of which is closely matched to the clear cross-sectional shape of the hollow profile bar.
  • the upper side 40 of the connecting element 4 ′ is provided with a concave recess 41, which is most easily produced by milling, the milling tool being transverse to the longitudinal direction of the connecting element 4 ′ and is parallel to its top 40 extending axis of rotation, so that the surface of the concave recess 41 takes the shape of part of a cylindrical surface.
  • This connecting element 4 ' is inserted to close a spacer frame in the two mutually facing ends of the spacer profile, so that the notches 42 and 43 lie exactly in the butt joint 27'; then the outer wall 12 'of the spacer profile is pressed in until it rests in the recess 41 on the upper side 40 of the connecting element 4' (FIGS. 9 and 10, left half).
  • the butt joint 27 ' is then sprayed out with a sealant and adhesive 44 (FIG. 10, right half), in particular with a butyl rubber such as e.g. Polyisobutylene, with which the flanks 10 'and 11' of the spacer frame must be coated anyway before they are installed in an insulating glass pane.
