Definitions

  • the present invention relates to a fire-resistant facade construction equipped with a swelling seal.
  • the invention relates to a facade construction of the curtain wall type.
  • curtain walls are known and built around a skeleton of profiles made from aluminium or the like in the form of mullions and transoms which form adjoining frames for façade panels, typically glass panels.
  • the panels are clamped along the edges against the aforementioned front sides of the mullions and transoms by means of screws which are screwed in the aforementioned screw channels through an insulation profile made from thermal insulation material which has been pushed into the screw channel in advance with an insert edge.
  • Said swelling seals are made of a material which in the event of a fire will swell up under the influence of the heat, with the intention of filling the space around the panels thereby preventing hot air from flowing to the non-burning side such that the flames are at least temporarily prevented from flashing over and no oxygen is supplied to the burning side which could fan the fire.
  • said swelling seals are glued separately on the aluminium profiles when building the facade construction, typically on either side of the ribs defining the screw channel.
  • Another disadvantage is that when applying the swelling seals at low temperatures and damp weather a bad adhesion of the glue is obtained and glueing in adverse weather conditions is thus not recommended.
  • the spacer of the swelling seal contains a U-shaped profiled section with legs which run essentially parallel with the swelling strips, whereby the form and the dimensions of said U-shaped section are preferably such that upon mounting the swelling seal it fittingly slides in the screw channel.
  • the swelling seal is first slid over said insert edge of the insulation profile with the U-shaped section, after which the assembly can be slid as a whole into the screw channel of the facade profile, such that the swelling seal is affixed.
  • a facade construction according to the invention containing a skeleton of profiles made from aluminium or the like in the form of mullions and transoms of adjoining frames for facade panels and which on their front sides facing the outside of the façade construction are provided with an open screw channel delimited by two parallel protruding ribs of the profiles which define a rebate in which the panels are attached with a certain lateral play by means of clamping profiles which cover the edges of the panels and which are clamped against said front sides of the mullions and transoms by means of screws which are screwed in said screw channels, wherein the facade construction is provided with swelling seals containing two swelling strips made of a material which in the event of a fire swell up under the influence of heat, the swelling strips being interconnected by at least one spacer which holds the swelling strips at a distance from each other and containing a U-shaped profiled section with legs that run parallel with the swelling strips, whereby the swelling seals are fittingly slid over the ribs of the screw channels of
  • Said type of swelling seal makes it easy to also use insulating parts (Hi-foam) in combination with a swelling seal.
  • the swelling seal according to the invention is slid over the ribs of the screw channel with the swelling strips on either sides of the ribs of the screw channel.
  • the swelling seal is kept in place by the insulation profile and the screws in the screw channel.
  • the advantage is that the swelling seal does not necessarily have to be glued.
  • the strips can be applied in all weather conditions, even in cold and damp weather.
  • the swelling seal is made as an extruded profile or a co-extruded profile if the spacer is made from another material than that of the swelling strips, for example from synthetic material.
  • Figure 1 shows the skeleton of a facade construction 1 according to the invention which is constructed from mullions 2 and transoms 3 in the form of profiles made from aluminium or the like.
  • the front sides of the profiles 2 and 3 facing the outside 4 of the facade construction 5 are provided with an open screw channel 6 that is delimited by two parallel protruding ribs 7 of the profiles 2 and 3 which define a rebate 8 in which, as shown in figure 4 , glass or other panels 9 are attached with a certain play S by means of clamping profiles 10 which clamp the edges of the panels 9 between seals 11 on the front side 5 of the profiles and the underside of the clamping profiles 10.
  • the clamping profiles 10 are screwed against the panels 9 by means of screws 12 which are screwed in the screw channels 6 through insulation profiles 13 made from insulation foam or the like which are enclosed in the screw channels 6 in the known way with a longitudinal insert edge 14.
  • the clamping profiles 10 and screws 12 are covered by means of finishing profiles 15 which are snapped onto the clamping profiles 10.
  • the facade construction 1 is made with swelling seals 16 according to the invention which are made with two parallel tape-shaped swelling strips 17 made from a material which in the event of a fire swell up under the influence of heat.
  • swelling strips 17 are interconnected by at least one spacer 18 made from synthetic material or the like which interconnects the swelling strips 17 and holds them at a distance A from each other which is essentially equal to the breadth B measured between the outsides of the two ribs 7.
  • the spacer 18 contains a U-shaped profiled section 19 with legs 20 which run essentially parallel with the swelling strips 17 at a distance from the swelling strips 17 equal to the breadth B' of the ribs 7 and which at their free end are each connected with a swelling strip 17 by means of a cross member 21 at a distance from both longitudinal edges 22 of the swelling strips 17, respectively at a distance C and D.
  • the form and dimensions of the swelling seals 16 are such that the swelling seals 16 can be fittingly slid over the ribs 7 with the U-shaped section 19 in the screw channels 6 with the opening to the outside 4 of the facade construction 1 and the swelling strips 17 fittingly over the outside of the ribs 7 and over the entire or practically entire length E of the ribs 7.
  • the swelling seal 16 is thereby first slid with the U-shaped section 19 over said insert edge 14 of the insulation profile 13 for example, after which the assembly can be slid as a whole into a screw channel 6 of the profiles 2 and 3, such that the swelling seal is affixed as shown in the figures 2 and 3 .
  • the spacer 18 may be made from another material than the swelling strips 17, in which case the swelling seals 16 may, for example, be co-extruded.
  • the entire swelling seal 16 is made from the same material by extrusion or the like.
  • the swelling strips are glued or co-extruded on a slat-shaped support made from synthetic material or the like which analogously as above are interconnected by a spacer.
  • the support and spacer can also be obtained by injection moulding, for example, and the spacer can also be interrupted lengthways of the swelling seal.
  • the insulation profiles 13 show a beam-shaped body 23, the breadth of which is approximately equal to the breadth on the outside of the ribs 7 of the screw channels 6 and which over a certain length fits on the side of the insert edge 14 between the swelling strips 17.
  • the swelling strips 17 overlap the body 23 over a said distance D and the body 23 protrudes with a section with length F from the swelling seal 16, whereby said section is or can be surrounded by insulating parts 24 with laterally projecting wings 25 from high-grade thermal insulation foam.
  • figures 5 and 6 show the situation for the mullions 2 with a swelling seal 16 and insulation profile 13 with essentially the same properties as aforementioned but a slightly deviating form and dimensions.
