Definitions

  • the invention relates to a fire protection facade with the features of the preamble of claim 1.
  • Fire protection facades comprise fire protection panels, which often consist of fire-resistant glass and are held between sealing strips. There is a glazing between two adjacent fire protection panels.
  • a pressure profile with facade screws is fixed against a base profile of the facade outside, with the facade screws extending through the glass rebate and the pressure profile fixed the fire protection panels between the sealing strips.
  • Fire protection facades must meet prescribed fire protection requirements, with a suitable solution is sought, which nevertheless achieves good thermal insulation in addition to the requirement of sufficient fire protection properties.
  • Required fire protection requirements not only affect the desired service life under the influence of high temperatures, but also the prevention of the spread of smoke, the spread of flames or the generation of toxic gases and possibly the limitation of the temperature increase on the side facing away from the fire.
  • a two-part support structure 4 which consists of a base profile 4a and a substructure 4b.
  • the shape of the previously known from the prior art support structure is given only by way of example and not significant for the understanding of the fire protection measures.
  • the base profile 4a holds inner sealing strips 5, which, as in the Fig. 2 and 3 illustrated examples, can also be designed in one piece.
  • fire protection glasses are 3.
  • a pressure profile is stretched using cladding screws 9 against the support structure and thereby fixes the fire-resistant glasses 3 between the outer sealing strips 6 and the inner sealing strip 5.
  • a Dämmsteg is arranged for better thermal insulation, in the in State of the art usual way of easily combustible plastic, such as PA, PP or ABS.
  • Intumescentst Shape 2 Intumescent materials are thermally irreversible foaming materials that fill and seal the cavities accessible to the intumescent material in the event of fire in the event of fire.
  • IntumescentstMail has the disadvantage that in addition to high material costs an additional Step means.
  • Another disadvantage of IntumescentstMail is that they have a high thermal conductivity and reduce the insulating effect of Dämmstege accordingly.
  • the EP 0 320 604 A2 describes a fireproof glazing system with fire-resistant glazing, wherein in the glazing between two adjacent fire-resistant glazing insulating material is arranged.
  • This insulating material is preferably covered with a seal.
  • the insulating material may consist of silicone foam, which silicifies in case of fire and then fills the limited space of the glazing elements, so that no flue gases can pass. In this way, temperature increases in the area of the frame should be reliably prevented.
  • the fixation of a facade outside pressure profile by means of facade screws takes place in separately provided, internally threaded bolts which are welded to the outside of the fire structure.
  • the EP 0 320 604 A2 represents the closest prior art.
  • the invention has for its object to propose a fire protection facade, which achieves a high thermal insulation without the use of Intumescentstsammlung, but still meets the fire protection requirements.
  • the invention is based on the idea to design a fire protection façade mentioned above in such a way that in the glass rebate there is an insulating body consisting of foamed material of low density.
  • foamed material of low density such, also known in the art as Dämmkeder insulating body has due to the open-pored or closed-cell structure with a variety of individual or interconnected cavities very good thermal insulation properties.
  • intumescent-free, foamed insulating body made of a material with low density because such insulating body has only a very small mass and therefore depending on the foam material used, possibly early burning, but at the same time only one generates very small amount of smoke and represents fire load.
  • the insulating body consists of a hydrocarbon-based polymer foam. This has the advantage that exclusively or largely predominantly hydrogen and carbon dioxide, but not highly toxic gases, are released when the polymer foam burns off. In this context, it has proved to be particularly advantageous to form the insulating body of PE foam, because polyethylene is completely hydrogen and Carbon dioxide burns. Although such insulating body are for example from the EP 1 127 990 A2 known, but not for a fire protection facade.
  • the sealing strips comprise a one-piece inner seal.
  • the sealing strips are preferably made of chloroprene or EPDM, the burning of the sealing material also occurs only in a temperature range or after an exposure time, which is advantageous for achieving the desired fire protection function.
  • the insulating body By extending the one-piece inner seal over the screw of the base profile and having a mounting receptacle for positive reception of the insulating body, the insulating body can be mounted in a convenient manner in Glasfalz Scheme by this is retracted into the mounting receptacle of the one-piece inner seal.
  • the inner seals are given sufficient stability even in case of fire over a prolonged period of time and as long as possible to maintain a firm connection with the fastening screw.
  • the fastening screw is made of refractory metal according to a preferred embodiment.
  • one or more additional holders made of steel or stainless steel can additionally be arranged on the pressure profile on the outside of the facade.
  • This additional measure is particularly advantageous if the pressure profile is made of aluminum.
  • the pressure profile made of aluminum can be produced inexpensively in the extrusion process and with the appropriate mounting geometries for the outer sealing strips but also the facade outside as Decorative element attached cover strips provided. Only in case of fire, after the melting of the aluminum pressure profile or over the length of several additional elements made of steel or stainless steel arranged on the outside in the area of the fastening screws, the function of the pressure profile.
  • the fire protection facade according to the invention has a Glasfalz Scheme, in which there are exclusively a one-piece inner seal, the insulating body, the facade screws and optionally glass blocks for the fire protection panels. In other words, there are no intumescent strips in the glazing area.
  • FIG. 1 is deliberately shown to be in substantial accordance with the prior art fire protection façade structures described above.
  • fire protection facade is shown in a sectional view. In the illustrated section, no glass blocks for the fire protection panels are shown. It should be clear, however, that in the bolt area, the fire protection panels are supported on glass blocks.
  • the support structure is provided in two parts in the present case and comprises a basic profile 4a made of steel or stainless steel and a substructure 4b shown in the present case as a hollow profile, which may have a different shape and may also consist of a solid material profile body.
  • a basic profile 4a made of steel or stainless steel
  • a substructure 4b shown in the present case as a hollow profile, which may have a different shape and may also consist of a solid material profile body.
  • aluminum and wood are also suitable materials for the substructure.
  • a one-piece support structure 4 made of steel or stainless steel is conceivable.
  • the basic profile is connected in the present embodiment with the substructure, wherein at reference numeral 11 both a screw or a suitable material pairing a weld is conceivable.
  • the basic profile has fastening lugs 12 for a one-piece provided inner sealing strip 5, which is hooked into the attachment lugs 12 and extends over the formed in the base profile screw 13.
  • At the inner sealing strip 5 are the fire-resistant glasses 3, the outside of the facade are again held by outer seals 6.
  • Both the inner seals and the outer seals are preferably made of chloroprene or EPDM, as these materials have proven to be suitable for fire protection facades.
  • the outer seals 6 are received in suitable receiving geometries of a pressure profile 7, wherein the pressure profile 7 made of steel, stainless steel or aluminum.
  • one or more auxiliary holder 8 are additionally provided.
  • the additional holders are made of steel or stainless steel and are provided either in the fastening screws 9 piecewise or continuously.
  • the fastening screws are made of refractory metal, such as steel or stainless steel and engage in the screw 13.
  • the inner seal 5 is provided in the area by extending over the screw with a mounting receptacle 14, which consists of a limited by two hook-like strips receiving space and the insertion of an insulating body 18 is used in the Glasfalz Scheme between the inner seal 5 and the Antikprofil. 7 is arranged.
  • the insulating body 18 consists of an optimized insulating material without the use of Intumescentmaterial. Foam material with low density has proven to be a suitable insulating material, preferably using PE foam.
  • the insulating body 18 is provided with a hammerhead-like projection 15, which is shaped so that it can be positively received in the mounting receptacle 14 of the one-piece inner seal 5.
  • the insulating body 18 of a foamed material with low density has only a very small mass, the insulating body burns with only a small amount of smoke, so that the required fire protection properties can still be achieved using the insulating body 18. At the same time a very good thermal insulation is achieved by the insulating body 18.
  • the advantages of the insulating body according to the invention over the solutions described in the prior art are that can realize significant cost savings. In particular, compared to the solution using a Dämmsteges with attached IntumescentstMail the material costs are significantly lower and the introduction of IntumescentstMail deleted. At the same time, however, an improved thermal insulation can be realized by using the foam spring 18, because both in Fig.
