Definitions

  • EP 0 717 165 B1 describes a fire-retardant profile component which is manufactured as a multi-chamber profile from light metal, preferably from aluminum, with an insulating web which reduces the heat flow.
  • the outer and the inner shell each delimit a hollow chamber. These two hollow chambers are connected by means of an insulating web and embedded bridge webs, so that a three-chamber profile is formed.
  • Fire protection panels are inserted into these chambers, which are fixed by means of metal springs. In the event of a fire, the fire protection panels release crystal water, which cools the aluminum profile and prevents the aluminum profile facing the fire from melting.
  • the disadvantage of this construction is that it is only suitable for fire resistance times of up to 30 minutes. Higher fire resistance times of 60, 90 or 120 minutes cannot be achieved with this.
  • DE 44 43 762 A1 discloses a fire protection element, in particular for building a framework on a building for holding a clampable component, such as fire protection glazing or a panel, which has a core profile, a heat-insulating filler material surrounding the core profile, and a casing surrounding the filler material and has an outer cover strip for clamping the component, the core profile, the filling compound and the casing forming a composite body.
  • the framework is designed in such a way that light-metal profiles with a melting point lower than the temperature to be expected in the event of a fire and which affect the metal profiles can be used on the side facing the fire, the melting of these supporting light-metal profiles being prevented over a predetermined safety period.
  • the invention has for its object to provide a fire-resistant profile component that can be produced with less effort and a method for its production, the profile component being suitable for simple and inexpensive manufacture to withstand fire resistance times of 30, 60, 90 and 120 minutes.
  • the profile component has a supporting inner and outer support shell, which by means of an insulating web, the z. B. is made of polyamide or PVC, is positively and positively connected, so that for normal use, ie not in the event of fire, a statically stable composite profile is formed.
  • This composite profile surrounds a single hollow chamber which is partially filled with a fire protection insulating material at least in a core area.
  • the fire-resistant profile component according to the invention is thus an advantageously thermally decoupled single-chamber composite profile.
  • first two essentially U-shaped profile parts in particular made of extruded aluminum, which form an inner support shell and an outer support shell, are connected at their free leg ends by means of thermally separating insulating webs to form a composite profile surrounding a single hollow chamber, and then the hollow chamber is partially filled with a fire protection insulating compound at least in an inner core area.
  • a fire protection insulating compound at least in an inner core area.
  • the fire protection insulation can, for. B. consist of a matrix of glass fiber reinforced mineral substances.
  • the fire protection protective effect of the profile component according to the invention results from the interaction of the individual components.
  • the outer or inner aluminum support shell of the composite profile melts, depending on the location of the fire.
  • the melting point of aluminum is 600-650 ° C.
  • this temperature is reached after approx. 10 minutes in accordance with the ETK (standard temperature curve), after 30 minutes the temperature in the fire furnace is 822 ° C and after 90 minutes at 986 ° C.
  • the insulating bars which are made of a mechanically strong material with low thermal conductivity, prevent the heat from migrating to the aluminum tray on the side facing away from the fire.
  • this aluminum carrier shell together with the fire protection insulation, forms the statically supporting cross-section.
  • the frame system consists of one There is a single-chamber profile because the large hollow chamber allows the insulating compound to form a stable block together with the aluminum support shell on the side facing away from the fire, which then takes on the static load-bearing function.
  • the fire protection insulating composition has an insulating effect due to its composition, this insulating composition advantageously releasing crystalline water under the action of heat, as a result of which the entire profile component according to the invention is cooled and thus the fire resistance time is positively influenced.
  • Another possibility of controlling the fire resistance times is achieved by increasing or reducing the depth of the insulating webs and thus the distance between the aluminum outer and inner shells.
  • Another option is to change the depth of the inner or outer shells. In the event of a fire, it cannot be predicted from which side the fire will hit the profile component and the profile component with all anchorages, fittings, glass and panel brackets must ensure that the room is closed, all of these parts are on the outer and inner support shell of the aluminum composite profile attached.
  • the particular economic advantage of the single-chamber composite profile according to the invention is that the open, U-shaped aluminum inner and outer support shells are less expensive to produce than aluminum hollow profiles, and that there is the possibility of using metal corner angles to make the single-chamber composite profiles like normal thermally insulated Process aluminum profiles into frames and fill the fire protection insulation compound into the prefabricated frame through the large hollow chamber.
  • the particular fire protection advantage of the single-chamber composite profile according to the invention is that a large amount of fire protection insulating material can be filled into the single-chamber composite profile through the large hollow chamber, which forms a stable insulating block in which the corner brackets and connecting means can be embedded. To this extent this is not possible with multi-chamber composite profiles. It is also particularly advantageous if the fire-resistant component according to the invention is filled with a fire protection insulating compound which contains magnesium oxychloride cement or magnesium oxysulfate cement or consists entirely of magnesium oxychloride cement or magnesium oxysulfate cement.
  • magnesium oxychloride cement has heat and sound insulating properties.
  • the cement has a high bulk density, which among other things has led to efforts to create pores in the sense of a lightweight construction.
  • the cement is also only partially water-resistant, so that despite its fire-retardant properties, it is only limited, i.e. e.g. has been used as a fire-retardant impregnating agent, not as a solid component.
  • the high corrosiveness of the material also played a role.
  • magnesia screeds also called magnesite screeds
  • Beams, frames and pipes must therefore be clad with bitumen paper or other barrier material before laying the screed.
  • the profile component according to the invention is a composite body which can also have a supporting function, a high bulk density of the cement has an advantageous effect. If necessary, however, a reduction in density can be advantageously achieved for profile components according to the invention which are used in particular in a non-load-bearing manner. Corrosiveness can be counteracted by, for example, applying a protective coat to the Inner walls of the hollow chamber applied or this is made of aluminum. A possibly less high water resistance than that of conventionally used material is insignificant due to the existing casing of the mass.

  • magnesium oxychloride-magnesium oxysulfate cement formed by admixing magnesium sulfate has a composition with a molar ratio of MgCl 2 / MgSO 4 of 1: (0.02 to 1.9).
  • Such a magnesium oxysulfate cement used in a fire protection element according to the invention can advantageously have a composition with a molar ratio MgSO 4 / Mg (OH) 2 / H 2 O of 1: (2.5 to 3.5): (6 to 10) ,
  • the filler of a magnesium oxysulfate cement can also be made with the addition of magnesium chloride.
  • a matrix with a qualitative composition can be formed, as described above for a magnesium oxychloride cement when magnesium sulfate is added.
  • An advantageous composition is a MgSO / MgCl 2 molar ratio of 1: (0.02 to 1.9).
  • a filling compound with a low chloride content is less corrosive than a filling compound with a high chloride content.
  • a mixed cement which is formed from magnesium chloride and magnesium sulfate is referred to as a magnesium oxychloride-magnesium oxysulfate cement if the proportion of magnesium chloride in the preparation of the composition is higher than the proportion of magnesium sulfate, and of a magnesium oxysulfate-magnesium oxychloride cement if the situation is reversed.
  • the water resistance increases on the one hand, but on the other hand the mechanical stability of the cement also decreases.
  • the purity of the raw materials used or crystal water contained in the salts must be taken into account from the outset.

Abstract

L'invention concerne un élément profilé (1) réfractaire servant à produire des fenêtres, des portes, des éléments muraux, des façades et similaires. Ledit élément comprend deux parties profilées sensiblement en U, notamment en aluminium extrudé, qui forment une coque support intérieure (3) et une coque support extérieure (4) et sont reliées, à leurs extrémités libres (300, 301 et 400, 401) des branches (5) du profilé en U, au moyen d'entretoises isolantes (6) à séparation par voie thermique, en un profilé composite (35) entourant une unique chambre creuse (H). La chambre creuse (H) est remplie au moins en partie avec une matière isolante ignifuge (7). Le principal avantage, en termes d'ignifugeage, du profilé composite à chambre unique selon l'invention réside dans le fait que l'unique chambre creuse (H) de dimensions importantes permet de remplir le profilé composite à chambre unique, d'une très grande quantité de matière isolante ignifuge, qui forme de ce fait un bloc isolant stable dans lequel les cornières d'angle et les éléments de jonction peuvent également être incorporés, ce qui n'est pas possible dans le contexte de l'invention, avec les profilés composites à chambres multiples connus. L'invention concerne en outre différentes variantes de production dudit élément profilé (1), qui prévoient entre autres l'utilisation d'une matière isolante ignifuge (7) durcissable à base de mortier, l'utilisation de parties en matière isolante préfabriquées et l'évidement de chambres partielles (37) non remplies, dans la chambre creuse (H).
