Definitions

  • the invention relates to frameless glazing (structural glazing), the edge regions of single or multi-pane glazing being attached to elements of the facade, such as facade posts and transoms, or element facades via load-bearing seals, in particular made of silicone rubber (see EP-A-0251834).
  • glazing is framelessly attached on two or four sides to facade profiles, such as facade posts and facade bars.
  • the glazing consists of a pane or insulating glazing made of two or more panes and is sealed directly onto the elements of the facades, the sealing not only performing a sealing function, but also providing static functions, such as the transmission of wind loads (wind pressure and wind suction) , and partly also carries the weight of the glazing.
  • the sealing is done in particular with a one- or two-component silicone rubber.
  • the invention has for its object to provide a frameless glazing, in which it is ensured that in the event of a fire, the pane or panes cannot fall off the building as a whole.
  • This object is achieved in that between the elements of the facades and at least the outer pane holder are arranged, which are attached to the glazing with a highly heat-resistant adhesive, and do not exert constraints on the glazing when the load-bearing seal is intact.
  • the arrangement of holders ensures that after a failure of the load-bearing seal in the event of a fire, the glazing cannot fall down as a whole, but is held and, if necessary, broken into smaller pieces by the action of heat.
  • Available high heat resistant adhesives are able to maintain their function at temperatures up to 1600 ° C and more. Temperatures of up to approx. 1200 ° C occur during the prescribed fire tests, so that adequate safety is guaranteed.
  • the silicone bonding takes over the removal of forces such as wind, temperature and sometimes. Own weight.
  • the glued brackets secure the pane.
  • the holders are preferably designed such that they can follow movements of the load-bearing seal, so that no constraints are exerted on the glazing when the silicone bond is flexible.
  • holders are arranged on the elements of the facade with play, so that a shift in the direction perpendicular to the plane of the glazing can take place.
  • a layer made of an elastic material preferably silicone, is arranged between a holder and a facade element, and the holder is slidably held on a screw or the like.
  • the holders are preferably of I, T, L or double T shape in cross section and engage in appropriately designed grooves or undercuts on the elements of the facade, such as facade posts and ledgers or on the element facades.
  • the holders are designed as springs and glued to the back or the peripheral edge of the outer pane of the glazing.
  • the holders are preferably made of metal and in particular stainless steel, so that cold bridges are avoided.
  • the outer pane of the glazing is secured by four brackets arranged at the corner areas.
