Definitions

  • the invention relates to an insulating glazing with holding system, which is preferably provided for a glass facade, with at least two glass panes, wherein at least one outer surface of a glass pane, the facade outside and at least one outer surface of a glass pane forms the facade inside, wherein the glass sheets are connected via at least one spacer and at least form a cavity between the glass sheets, wherein a support structure is provided with holders for the insulating glazing.
  • VSG Vinyl s afety g las
  • PVB polyvinylbutyl
  • the glass sheets are very often held as a filler by frame structures.
  • a holding system for insulating glazings described In this writing is in FIG. 2 a multi-pane double-glazed windows shown, with two staggered glass panels are mounted on the facade outside with the support structure located on the inside of the facade.
  • This holding system shows a visually disturbing edge surrounding the insulating glazing.
  • These frame structures and brackets look visually very disturbing, especially because of the transparent glass. So it is the desire of many customers to reduce these annoying frame parts and brackets or omit.
  • the inventor has made it his mission to make insulating glazings, preferably for glass facades, such that in compliance with all safety-relevant requirements optically disturbing frame and fixtures are largely avoided.
  • the support elements meet the task according to the required regulations to derive the weight of each individual disc, in case of failure of the central Scheibenverklebung on the building.
  • This is achieved in that the support element at least partially surrounds the glass panes, whereby a positive connection of the glass pane, which form the facade inside and the glass pane which forms the facade outside, is created.
  • a positive connection in which parts contours interlock is on Dubbel: "Paperback for Mechanical Engineering” 15th edition; See chapter Component Connections on page 388.
  • the support elements can be chosen in their dimensions so that they are barely visible on the facade exterior and facade interior. The previously visually very disturbing frame systems are thereby avoided and it creates the impression of a glass façade.
  • Such a support element can be realized in a particularly simple manner by means of at least one elongated connection element.
  • an elongated connection element the inventor understands elements such as a wire, a string or a closable clip element of metal and / or plastic, which circulate the insulating glazing in the region of a corner in a closed path.
  • Such a closed track can be realized by a wire whose ends are twisted.
  • This elongated connecting element creates a mechanical connection between the outer side of the facade and the facade inside glass pane and thus the legally required mechanical connection of all glass with the building. A pure bond is not a legally compliant connection.
  • the at least one elongated connecting element extends at least partially in at least one groove.
  • the groove prevents the elongated connecting element from slipping off.
  • the groove acts as a predetermined breaking point of the glass pane.
  • Such a groove can particularly easy on the glass surface, the outer facade surface, and / or on the glass surface, which forms the facade inner surface, are ground.
  • the groove can also be mounted on one or both sides of the edge of the glazing.
  • a variant of the holding system may be that the support elements consist of at least 2-legged angles whose leg length extends only over part of the edge length of the double glazing. These angles are attached to the insulating glazing, for example by a safety wire, which surrounds the insulating glazing at the edge.
  • the supporting elements are mainly made of metal because of their supporting function. Due to their heat-conducting properties, metals show the undesired effect of thermal bridge formation already described above. For this reason, a limitation of the leg length of the support elements makes sense.
  • the resulting gaps between two adjacent insulating glazings can be inexpensively sealed, for example with a transparent silicone.
  • the support elements transferred in the event of failure of the adhesive bond, the weight of the outside facade glass panels to the support structure and thus to the building. Since other forces, for example shear forces, act on the glass panes on facades, partly due to wind pressure and wind suction, a more homogeneous force transfer to the building is made possible by the 2-limb structure of the support elements.
  • the inventor also proposes that the width of the angle is adapted to the edge of the insulating glazing, that both the outside of the facade forming glass as also the facade inside forming glass is supported by the support element wherein the angle is not wider than the edge width of the double glazing.
  • the inventor has recognized that the support elements should be designed so that they can not fall out of the spaces between adjacent glazing. For this reason, the inventor proposes to make constrictions along the leg length of the support elements. These constrictions, which engage the edge of the insulating glass, act as a mechanical locking of the support elements. In addition, can be inserted in these constrictions of the edge on the circumference of the insulating glazing security wire, which thus fixes the support member to the glazing.
  • the support elements may have at least one retaining element per leg.
  • This holding element can be realized by simply punching or folding a leg part surface at the leg end or at the leg intersection.
  • insulating glazings often have an elastic bond between the adjacent glass panes in the edge region. In the bond, the holding elements can be easily pressed.
  • a particularly secure method to attach the support elements to the glazing is a screw connection of the support elements with the spacers of the glazing.
  • connection surfaces which are arranged perpendicular to the leg surface.
  • These connection surfaces can open the façade outside of the glazing, preferably exclusively on the outside facade of the glazing, be arranged.
  • the connecting surfaces can be welded as triangles or quarter-circular surfaces between the legs of the support elements. If, for example, a wind suction, the glass pane of the facade outside of the bond with the spacer to solve, it prevents the glass pane can fall down as a whole piece.
  • the connecting surfaces cause splintering of the glass pane. This function is required by a legal requirement. So far, these so-called emergency brackets were usually designed as a full-page surrounding frame. In the embodiment of the invention, the connecting surfaces in the corners form the required emergency brackets. Since these connection surfaces do not wrap around the insulating glass on the complete side, they are visually barely perceptible.
  • An advantageous embodiment of the invention provides that in the glass pane, which is arranged to the facade inside, at least one opening is attached.
  • This opening may be a bore which has a smaller cross-section towards the inside of the facade, for example a conically narrowing bore.
  • the composite construction of the glass pane but also allows a layer by layer step-shaped cross-sectional constriction of the opening.
  • the opening which can be realized very easily, acts as a connection point of the holder with the insulating glazing.
  • connection point engages a bolt element elastically connected to the holder. Since laminated safety glass, especially in the area of edges, are very susceptible to breakage, this elastic storage makes sense.
  • the elastic bearing can be realized by a rubber sealing element which is arranged between the contact surface of the opening and the engaging bolt element. But also an elastic storage in the form of a vibration damper between a holder of the glazing and the support structure is conceivable.
  • the insulating glazing with holding system to use insulating glazings having two or more cavities.
  • the heat transfer coefficient of the insulating glazing generally referred to as k value or U value can be reduced.
  • the loss of heat output per façade surface is thereby reduced and follows the positive trend towards energy savings.
  • the support elements according to the invention have a positive effect on the unwanted heat losses, occupy a minimal area of the total facade and thereby represent only minimal heat or cold bridges.
  • FIG. 1 shows an embodiment of the support element according to the invention.
  • the support element consists of a 90 ° angle 5, which was made of a flat material with two equal long about 50 mm long legs. At the two leg ends partial surfaces are folded, which form the holding elements 7. These retaining elements 7 can engage in the edge sealing of the insulating glazing 1.
  • the attachment of this support element is very simple by, for example, a flat metal wire, the edge of the circumference of the insulating glazing and the angle 5 rotates realized.
  • FIG. 2 shows a further embodiment of the support element according to the invention.
  • the structure of the angle 5 corresponds to the structure of the angle 5 from FIG. 1 , only in this embodiment, in addition, a triangular connecting surface 8 in the vicinity of the leg intersection point attached.
  • This connection surface 8 acts as an emergency support for the glass pane 2 b 'of the facade exterior of an insulating glazing 1.
  • FIG. 3 shows a section perpendicular to the glass sheets 2, 2a ', 2b' of an insulating glazing invention 1.
  • This insulating glazing 1 is formed by three glass sheets 2, 2a ', 2b'.
  • a glass pane 2a ' forms the façade outside and two glued glass panes 2, 2b' are located on the façade inside, with only the glass pane 2b 'forms the facade inside.
  • the glass sheet 2a ' is connected to the glass sheets 2,2b' by means of a spacer 3. This creates between the glass sheets 2a 'and 2, a thermally insulating acting cavity 4.
  • the holder 12 of the support structure 11 are exclusive attached to the glass sheet 2b '.
  • a groove 9 is ground.
  • a wire 10 here a stainless steel wire, inserted and stretched around the glazing 1 and twisted at its ends. This results in a mechanical connection of the glass pane 2a 'with the glass pane 2b'.
  • FIG. 4 shows a double glazing 1 with a, running in a groove 9 and the insulating glazing 1 rotating wire 10.
  • a stainless steel wire 10 is inserted, which is stretched around the insulating glazing 1.
  • This wire 10 forms the support element in this embodiment. But it can also be attached in addition a 2-legged angle 5, wherein the wire 10, the two legs and the insulating glazing 1 can rotate. This results in a particularly secure design of the glass pane support.
  • FIG. 5 shows a further possibility, a wire 10 in the region of the corners of an insulating glazing 1, to secure a glazing 1.
  • two grooves 9 are ground at the edge region of two adjacent edge sides of the insulating glazing 1.
  • FIG. 6 shows a view from the facade inside of an insulating glazing 1 according to the invention with brackets 12 and supporting structure 11.
  • the insulating glazing 1 consists of three glass panes 2, 2a ', 2b', wherein the glass pane 2b 'forms the facade inside.
  • the glass panes 2, 2b ' are adhesively bonded to the glass pane 2a' forming the facade outside. Only the glass pane 2b 'is connected directly to the support structure 11 via the brackets 12.
  • the glass sheet 2 is glued flat with a PVB film to the glass sheet 2b '.
  • the glass sheet 2a ', which is glued with spacers 3 to the glass sheet 2 is additionally by the support members 5 (in FIG. 6 not shown) secured against accidental falling out.
  • FIG. 7 shows a section through the insulating glazing 1 according to the invention with a holding system in the plane in which the opening for the bolt member 14 extends.
  • the insulating glazing 1 consists of three 8 mm thick laminated safety glass panes 2, 2a ', 2b', wherein the glass pane 2b 'forms the facade inside. Via a spacer 3 and a 16mm wide cavity 4, the glass sheets 2, 2b 'with the facade outside forming glass sheet 2a' glued.
  • the glass pane 2b ' there is an opening 13 which tapers conically towards the inside of the facade.
  • FIG. 8 shows a view of the facade inside of an insulating glazing 1 according to the invention with a holding system.
  • the insulating glazing 1 also consists in this embodiment of three each 8mm thick laminated safety glass panes 2, 2a ', 2b', wherein the glass sheet 2b 'forms the facade inside.
