Definitions

  • the invention relates to a multi-pane Isoller glass with at least two parallel panes, which are surrounded by a frame formed from plastic profile bars, each pane engages with its edge in a glass retaining groove of the frame and between at least part of the groove wall and the pane engaging therein there is an adhesive sealant and the frame has a film-like vapor diffusion barrier layer at least in the region of the space between the adjacent panes.
  • Plastic profiles offer many advantages over other materials, such as wood, aluminum and the like. Like., But they are not vapor diffusion tight.
  • a vapor diffusion barrier layer must be provided which prevents or at least considerably complicates the penetration of water vapor into the space between the panes.
  • the vapor diffusion barrier layer is embedded in the plastic profile rod when it is extruded.
  • this method of production is relatively complex and, on the other hand, it is problematic to carry out the barrier layer up to the edge of the profile bar.
  • the shape of the barrier layer is largely predetermined by the cross-sectional shape of the plastic profile rod, which leads to a compromise in the formation of the vapor barrier.
  • the object of the invention is to provide a multi-pane insulating glass of the type mentioned, which ensures a particularly good design of the vapor barrier in a frame made entirely of plastic with the exception of the vapor diffusion barrier layer with the simplest and therefore most economical structure.
  • the multi-pane insulating glass is designed in accordance with the preamble of claim 1 in accordance with the characterizing part of the first claim.
  • the two-part design of the plastic profile bars eliminates the expensive process of embedding the vapor diffusion barrier layer when extruding the plastic profile. Instead, the film-like vapor diffusion barrier layer is placed on one part of the plastic profile rod and subsequently connected to the other plastic profile part. The barrier layer can easily extend over the entire width of the space between the two panes.
  • the material for the plastic profile bars is primarily polyvinyl chloride (PVC).
  • a preferred embodiment of the invention provides that the two plastic profile rod parts are held together by means of a snap-in or snap-in connection device and the connection device is at the same time a holding device for the film-like vapor diffusion barrier layer.
  • the one plastic profile bar part has essentially the shape of a U-rail and the free ends of the legs are each designed as one half of the snap-in connecting device and that the one plastic profile bar part forms at least part of a spacer for the washers.
  • the two-part design of the plastic profile bars means that there is no additional effort, because the one plastic profile bar part can still be used as a spacer or at least as part of the latter, and even with previously known multi-pane insulating glasses, the spacer is a separately manufactured part.
  • the snap or snap connection of the two parts of the plastic profile bars allows the use of the same material and thus the formation of the plastic spacer, which is much more advantageous than the use of the known Aluminum spacers.
  • An object of the invention is also seen here. Otherwise, the other plastic profile rod part is the main component of the plastic profile rod and thus the frame.
  • a further embodiment of the invention provides that the film-like vapor diffusion barrier layer to form a chamber for a moisture-absorbing agent is overlapped by the U-center web of the one plastic profile rod part, the vapor diffusion barrier layer resting on the other plastic profile part.
  • the support surface is expediently designed to be flat, which enables the use of a flat barrier film.
  • An aluminum foil is preferably used for the latter.
  • a particularly advantageous variant of the invention provides that the longitudinal edges of the film-like vapor diffusion barrier layer protrude beyond the snap-in connecting device of the two plastic profile rod parts and extend into the interior of the glass holding grooves.
  • the flexible material of the barrier layer film allows the protruding longitudinal edge to be shaped in any way and thus the diffusion path in the area of the glass holding groove to be designed as required. The longer you choose the vapor diffusion route, the more effective it is this vapor diffusion barrier.
  • the protruding longitudinal edge of the film-like vapor diffusion barrier layer advantageously extends into the glass holding groove approximately perpendicular to the pane plane before the pane is inserted.
  • the edge of the pane presses the protruding longitudinal edge of the barrier layer inwards, as a result of which both edges lie flat against one another.
  • the edge of the barrier layer protruding into the latter can be bent inwards.
  • the use of an aluminum spacer is customary in the previously known multi-pane insulating glass.
  • the special way of holding the barrier layer made of aluminum foil or the formation of protruding longitudinal edges of the barrier layer protruding into the glass retaining groove now enable the connection of aluminum and glass in a very advantageous manner despite the use of a pure plastic profile for the frame. There is no need to apply a primer that is usually required for plastics because this task is performed by the longitudinal edge of the barrier layer.
  • the loose, clamped locking layer and the two-part design of the plastic profile bar have the advantage that one can do without the primer application step and still get a perfect connection between the panes and the frame.
  • the steam diffusion path is extended.
  • this embodiment allows the use of plastic, in particular PVC, for the entire frame, including the spacer, which is also another object of the invention.
  • the protruding longitudinal edge of the film-like vapor diffusion barrier layer extends inclined to the plane of the pane in the direction of the mouth of the glass holding groove before the pane is inserted, and the free edge of the longitudinal rim is at a distance from the inner wall of the outer web Glass holding groove.
  • a strand or a bead of silicone is preferably placed on the base of the glass holding groove, while a bead of polysulfide, such as Thiokol (registered trademark) and the like, is applied to the outwardly facing surface of the barrier layer edge.
  • Silicone has particularly good adhesive properties, while Thiokol is characterized by rapid setting.
  • the longitudinal edge of the barrier layer protruding into the glass holding groove can be kept wider than in the first embodiment and consequently, when the pane is inserted, it clings to a larger area than is the case with the first embodiment. This not only benefits the better connection, but also the extension of the diffusion path and thus the improvement of the vapor barrier.
  • each glass holding groove there is a sealing strip, which is preferably formed on both sides and extends in the interior thereof.
  • These sealing strips take on the task of centering the pane as well as sealing the glass retaining groove from the outside.
  • the penetration of dust and moisture into the glass holding groove is prevented by these sealing lips and, on the other hand, they prevent the adhesive sealant from escaping when the pane is inserted into the glass holding groove.
  • the adhesive sealant in the glass holding groove is subjected to a compression by the disc, which ensures that the adhesive sealant is pressed even into the most distant groove and corner of the glass holding groove.
  • a first sealing strip of each glass retaining groove is expediently molded onto the one plastic profile rod part and a second sealing strip onto the other plastic profile rod part, the first sealing strip being designed as a soft sealing strip and the second as a hard sealing strip. Since the inner sealing strips of each glass retaining groove are softer than the outer sealing strips, the glass pane can at best be moved against the soft sealing strip and thus against the spacer under the influence of the compression pressure. This means that the adhesive sealant in the gap between the pane and the spacer is under a pressure which is sufficient to completely fill this gap.
  • Another advantage of using at least one soft sealing strip is that the gap formed by the two sealing strips can be elastically widened and chipping at the edge of the pane is prevented when it is inserted.
  • the formation of the plastic profile bar from two parts or the use of a plastic spacer has proven itself, because the spacer-side sealing strip can be molded onto the spacer.
  • plastics technology it is now easily possible to form part of the cross-section with a hardness other than the rest of the cross section. In this respect, it is therefore not a problem to produce the plastic profile rod part or the spacer with the necessary hardness and to form a sealing strip which is softer in comparison therewith.
  • At least the first sealing strip advantageously has an approximately wedge-shaped shape and preferably runs inclined into the interior of the glass holding groove. As soon as the compression increases when the pane is pressed into the glass retaining groove, at least the softer sealing strip is raised by the adhesive sealant and thereby pressed even more firmly against the pane.
  • the groove side walls of the glass retaining grooves are preferably roughened, in particular provided with longitudinal grooves or the like, in order to achieve better anchoring of the adhesive sealing compound.
  • the lower tooth in cooperation with the connecting device for the two plastic profile rod parts, can be used to automatically give the projecting longitudinal edge of the vapor diffusion barrier layer a predetermined position in the glass holding groove after the plastic profile rod parts have been assembled.
  • This lowermost tooth or the like can serve as a deflector or stop for the longitudinal edge of the film.
  • a further embodiment of the invention provides that there is a longitudinal support strip or the like.
  • This support strip or the like forms a stop at which the insertion movement of the pane into the glass holding groove ends. It ensures that there is still adhesive sealant at least below part of the front edge of the pane. Since the support strip or the like prevents the lowering of the pane to the bottom of the glass retaining groove, the multi-pane insulating glass according to the invention for curing the adhesive sealant can be stored vertically in a very advantageous and space-saving manner.
  • the plastic profile rods prefferably be attached to the panes when they are in the vertical position, so that even the largest insulating glass panes can be produced with a minimal space requirement.
  • the support strip or the like can be attached to the bottom of the glass retaining groove in the middle or offset, i.e. H. the disc does not necessarily have to be supported in the middle region of its front edge.
  • a special embodiment of the invention is characterized in that the inner wall of each glass holding groove is formed in its outer region by a plastic profile rod part and in its inner region by the other plastic profile rod part, on which the outer wall of each glass holding groove is molded, and in that one web of the other plastic profile rod part is formed at the same time forms the inner part of the glass holding groove and part of a fastening groove for fitting parts, which is open opposite to the glass holding groove.
  • the inner wall of each glass holding groove is formed in its outer region by a plastic profile rod part and in its inner region by the other plastic profile rod part, on which the outer wall of each glass holding groove is molded, and in that one web of the other plastic profile rod part is formed at the same time forms the inner part of the glass holding groove and part of a fastening groove for fitting parts, which is open opposite to the glass holding groove.
  • a very important design of the multi-pane insulating glass, the frame of which consists of miter-worked plastic profile bars, can be seen in the fact that the glass-holding grooves are connected to one another at each miter surface via a transverse channel which is accessible from the outside.
  • the glass-holding grooves are filled in by the adhesive sealant when the panes are inserted up to their miter ends, so that no sealing problems occur at this point. Accordingly, the critical point is only the connection of the two miter surfaces. If you now connect the two glass retaining grooves at each corner to each other via a transverse channel, you can introduce a flowable, curable sealant, for example injection, through the bore that leads to the outside.
  • the miter-side ends of the U-legs of a plastic profile rod part are provided with a recess in their area assigned to the chamber for moisture-absorbing means to form the transverse channel and this or the like at both ends by means of a plug. is closed, each stopper forming a wall of the transverse channel.
  • the stopper not only prevents the subsequently injected sealing material from penetrating between the grains of the moisture-absorbing agent, but rather creates the conditions for generating sufficient pressure in the injected sealing material so that it squeezes into the last crack and thus a 100 percent seal in guaranteed this area.
  • Each transverse channel is advantageously accessible via a bore and filled with a sprayable sealant.
  • the invention also relates to a method for producing the multi-pane insulating glass with at least two parallel panes, which are surrounded by a frame made of plastic profile bars with miter surfaces, each pane engaging with its edge in a glass holding groove of the frame and between at least one part the groove wall and the disk engaging in it an adhesive Sealant is located and the frame has a film-like vapor diffusion barrier layer at least in the area between the panes.
  • the task is to create a process for the production of this melamine insulating glass which, with the use of simple and inexpensive basic elements, enables rapid, problem-free, space-saving production which meets the requirements for high quality of the framed multi-pane insulating glass.
  • the plastic profile rods or the plastic profile rod parts can be produced in a simple manner by extrusion, preferably from PVC (polyvinyl chloride).
  • PVC polyvinyl chloride
  • the vapor diffusion barrier layer which preferably consists of an aluminum foil, is fastened at the same time.
  • the profile bars are preferably attached to the cleaned and spaced disks in such a way that one of these profile bars is held in a suitable manner and the disks are mounted thereon in a vertical position. Subsequently, the remaining three profile bars are pushed onto the previously formed unit.
  • the adhesive sealant previously introduced into the glass holding grooves, in particular injected, is displaced from the penetrating edge of the panes, so that it fills the entire glass holding groove. After curing, a firm, tight connection is created between the profile bars and the panes.
  • sealant is injected into the four transverse channels connecting the glass retaining grooves on the miter surfaces with such pressure that it completely fills these transverse channels.
  • the profile bars are held together by suitable devices until the sealant and the adhesive sealant in the glass holding grooves have hardened.
  • the loose plastic profile rods are advantageously mitered after the plastic profile rod parts have been joined together, so that smooth, continuous miter surfaces result and the film-like vapor diffusion barrier layer extends into the miter surfaces.
  • a further development of the invention is characterized in that the end faces of the plastic profile bars serving as spacers are provided on both sides with a recess in order to produce a connection between each glass holding groove and the associated end of the transverse channel for the sealant.
  • the recesses can be made, for example, by milling the front ends of a plastic profile rod part at the relevant points or by punching the recess.
  • Another embodiment of the invention is characterized in that the one, at least partially forming a spacer, the plastic profile rod part of the loose profile rods is provided with holes which are stamped in particular after assembly. Punching in the assembled state is possible because the surface in question of one profile bar part has a sufficiently large distance from the preferably parallel surface of the other profile bar part that is necessary to form a chamber for the moisture-absorbing agent.
  • web recesses, bores and the like for fitting parts are made on the plastic profile bars before the adhesive sealant is introduced. Carrying out this operation on the loose profile bars is important because the web recesses and the like are also used, for example, for inserting holding elements with which the profile bars are held together during the curing of the adhesive sealant.
  • a moisture-absorbing agent be filled into the chamber formed by the vapor diffusion barrier layer and the one plastic profile rod part and closed at one end by means of a stopper, and then the other end of the chamber is also closed by means of a stopper. It is expedient to introduce the moisture-absorbing agent into the chambers of the frame before the frame is formed, because it is then possible to dispense with an outward-opening fill opening, the sealing of which would require a complex operation. In addition, the complete filling of the chamber of each individual profile bar is easier and safer to carry out than the filling of a peripheral chamber of the finished frame.
  • An advantageous development of the invention is characterized in that the protruding longitudinal edges of the vapor diffusion barrier layer projecting into the glass holding grooves are at least largely bent into the interior of their glass holding groove before the adhesive sealant is introduced. This ensures that they assume their intended position correctly in the final assembly position of the panes and, on the other hand, this facilitates the introduction of the adhesive sealant.
  • Another variant of the invention is characterized in that on both sides of the protruding longitudinal edge of the vapor diffusion barrier layer protruding into each glass holding groove, a strand of adhesive sealant is introduced, in particular injected, and subsequently these longitudinal edges are pressed into the glass holding groove by the entering edge of the pane while nestling against the latter will.
  • a strand of adhesive sealant is introduced, in particular injected, and subsequently these longitudinal edges are pressed into the glass holding groove by the entering edge of the pane while nestling against the latter will.
  • a further embodiment of the invention provides that the panes are inserted into the lower plastic profile bar in an approximately vertical position and then the three remaining plastic profile bars are pushed onto the free pane edges.
  • the adhesive sealant When the panes are pressed into the glass holding grooves, the adhesive sealant is displaced and a small amount of the miter surfaces can also escape. As a result, it is usually not necessary to coat the miter surfaces with adhesive sealant. Because the adhesive sealant takes some time to reach its final state and harden, the profile bars must be held together in a suitable manner to ensure a tight corner connection.
  • the corners of the frame formed from plastic profile bars are held together by means of, in particular, insertable and / or snap-in corner brackets, the corner brackets being fastened before the sealant is injected. The latter is injected into the longitudinal channel connecting the two glass retaining grooves in the miter area.
  • a firm pressing together of the miter surfaces requires a correspondingly precise design of these corner angles and precise recesses, in particular notches or the like. If one chooses a latching or hooking connection of the corner brackets with the two profile bars of this corner, one can do without special fastening elements for the corner brackets, such as screws or the like. If you choose the corner angle to be particularly small, which is advantageous in itself, and assigns it, for example, to the area of one pane, it can be advantageous if an element is also attached in the area of the other pane, which holds the profile bars together at this point .
  • an additional angle in addition or as an alternative to the corner angle, an additional angle, in particular a plastic angle, is inserted into an outer fastening groove and is preferably connected to the frame by means of ultrasound, the additional angle being fastened before the sealant is injected.
  • Both angles and the like can be used in suitable grooves of the profile bars, which can be easily molded when extruding the PVC profile bars.

  • a corner bracket 31 is inserted into a frame groove 30 in each corner, which has an extension 32 on each of its legs, which extends into a web recess 33 engages and is supported on the edge 34 of the web recess 33 adjacent to the miter surface 29 (FIG. 3). This corner bracket 31 pull the miter surfaces 29 firmly together.
  • angles 35 are used at the four corners, which can in particular consist of plastic. They are inserted into a fastening groove 36 and are preferably connected to the plastic profit rods 6, 7 by ultrasonic welding. These angles 35 consist of metal in FIG. 3 and are equipped with threads for screwing in threaded bolts 47.
  • a longitudinal support bar 37 on which the completely inserted pane 4 and 5 is supported. It can be arranged and dimensioned such that the disc 4, 5 can be placed against it, but a layer of adhesive sealant 14, 15 remains between part of the disc end edge and the groove base. Thus, the adhesive sealant 14, 15 can be set with the insulating glass standing vertically. It is therefore expedient to attach the frame 3 to the vertically standing panes 4, 5.
  • the webs 38 and 39 of the one plastic profile rod part 8 form part of the glass retaining groove 1, 2 in FIG. 5 and at the same time also the outer grooves of the fastening grooves 36 and 40 for fitting parts (not shown) which are used there as window casements when using the framed multi-pane insulating glass , for example, clip.
  • the miter surfaces 29 form critical points.
  • the two glass retaining grooves 1, 2 of the two profile rod ends of each corner are bridged by an injectable sealant 41. It is applied with such pressure that it squeezes into all the cracks in this area and thus securely seals the miter surface 29 inwards.
  • the two U-legs 11, 12 of the plastic profile rod part 9 are provided in the miter region with recesses 43 which extend to the vapor diffusion barrier layer 17 according to FIG.
  • the sealant 41 can thus also contact the inward-facing surface of the barrier layer 17.
  • the web 22 has at least one of the two profile rod ends with a bore 45, to which a corresponding spray nozzle can be attached.
  • the spray nozzle is pulled off, which then also fills the bore 45, as illustrated in FIG. 1 of the drawing.
  • the sealing means 41 cannot penetrate between the grains of the moisture-absorbing means 24, the two ends of the chamber 23 assigned to each corner are closed by means of a plug 46 each.
  • This has a cap-like shape, the opening being assigned to the transverse channel 42, so that the plug 46 can also be filled with sealant 41.
  • the two plugs 46 thus also limit the transverse channel 42 at the same time.
  • the plastic profile bars 6, 7 or plastic profile bar parts 8, 9 are produced by extrusion and brought to the necessary length.
  • the vapor diffusion barrier layer 17, which consists of an aluminum foil is placed on the web 22 of the plastic profile rod part 8.
  • the plastic profile rod part 9 is placed over it and the two plastic profile rod parts 8, 9 are clipped together by snapping the connecting devices 10 together.
  • so-called yard goods that is to say, for example, six-meter-long profile rod bars, in which the barrier layer 17 has already been applied, and then to cut them to length. This has the advantage that after cutting or Miter saws do not have to rework the vapor diffusion barrier layer 17.
  • the recesses 43 are now made at the two miter ends by milling, for example with the aid of an end mill.
  • the one plastic profile rod part 9 is provided with the holes 25. They can be drilled or preferably also punched without a die.
  • the profile bar part 8 As well as the web recesses 33 and the bore 45.
  • each chamber 23 After the moisture-absorbing agent 24 has been filled in, the two ends of each chamber 23 are closed with the aid of a stopper 46.
  • At least one strand of adhesive sealant 14, 15 is now introduced into the glass holding grooves 1, 2. If necessary, at the same time or before, in the case of two strands, possibly also after the lower strand has been introduced, the longitudinal edge 21 of the vapor diffusion barrier layer 17 projecting beyond the connecting device 10 is bent or at least pre-bent.
  • the plastic profile rod 7 prepared in this way is now inserted into a profile receptacle of a glass reef.
  • the two cleaned and dried panes 4, 5 are then fed to the glass reef at a predetermined distance and preferably in an upright position.
  • After aligning the washers 4, 5 and the lower plastic profile rod 7, both are put together.
  • the glass holding grooves 1, 2 are completely filled with adhesive sealant 14, 15.
  • Sufficient adhesive sealants 14, 15 are normally located on the miter surfaces 29 to securely seal the miter surfaces 29.
