Definitions

  • the invention relates to a one-piece extruded, fire-protected Multi-chamber hollow profile made of aluminum or the like for the production of Frame elements for doors, windows, facades, glass roofs, partitions and the like, with an inner and outer chamber and at least two spaced, with the heat transport reducing, than in a row Arranged elongated holes formed openings provided the central webs Inner and outer chamber in which fire retardant materials are used, connect, with the central webs provided with the openings a spatial Form lattice structure and in the middle webs webs between the punched slots remain.
  • Hollow profiles of this type are known in various designs. It is from special importance that these are heat and heat resistant, so that Hollow profile in the event of fire before it is destroyed by exposure to heat for as long as possible resists. Therefore, such profiles are mostly made in one piece, i.e. the the center webs connecting the inner and outer chamber are made with the shells extruded in one piece.
  • composite profiles are known in which the inner and outer chambers are connected to one another by insulating webs made of a heat-insulating material, e.g. Plastic. In doing so the outer and inner shell pressed separately and subsequently through the insulating bars together. Since the insulating bars have a relatively low melting point, there is a risk when using such known profiles that they Exposure to heat no longer meets the requirements of today's fire protection correspond.
  • the first-mentioned embodiment in which the hollow profile is pressed in several parts, is primarily concerned with reducing the heat loss between the outer and inner shell of a profile. Increased fire protection can only be achieved through complex additional measures due to the insulating materials used for insulation with a very low melting point.
  • an insulating web made of a corresponding material is also used to reduce the heat loss. Because of the slot profiles lying one above the other in one plane, the only bridging web of the hollow profile is on the one hand excessively weakened, so that in the event of a fire the insulating strip made of the thermally insulating material is destroyed even at a low temperature. On the other hand, due to the extreme weakening of the remaining cross-section of the bridging bar, sufficient strength and overall stability of the window and facade construction, as specified by the fire protection requirements, can never be achieved.
  • the present invention is therefore based on the object of being fire-protected To form a multi-chamber hollow profile of the type described at the outset, that with favorable thermal insulation properties and low material use an im A sufficiently stable hollow profile as part of an overall structure arises.
  • the elongated holes around each central web preferably half the length of the elongated holes of the spaced apart are offset in such a way that within the grid of the opposite central webs in the axis of the elongated holes arranged in series, the ratio of the total length of the lattice webs to the length of the multi-chamber hollow profile is in a range of less than or close to 5%.
  • the spatial lattice structure formed creates an inherent stability for the in the loads that occur in practice on a building construction formed from it achieved that the static requirements of such fire protection constructions in fully sufficient.
  • This grid structure is concretely determined by the individual, reached with the central webs provided with the openings, which connect the inner and Take over the outer chamber.
  • the spatial lattice structure enables the remaining material content within the grid of each central web to less than 5% the total length can be limited.
  • each one Mittelsteges can be produced in a simple manner if the openings in one Row lie and are designed as elongated holes, because they then with a very simple tool can be punched out. So that the spaced Center webs within the grid are evenly loaded, that the elongated holes of a central web are preferably half the length of the Elongated holes of the spaced other central web are offset.
  • the fire retardant used in the inner and / or outer chambers Materials there are positively and / or non-positively held.
  • additional mechanical clamping or fastening elements such as clips or the like can be omitted.
  • the Length of the elongated holes and the length of the grid bars on the length of the middle bar are constant. Although this will result in a sufficient reduction in the Heat conduction is achieved with sufficient stability, it can in certain Applications be advantageous that the lengths of the elongated holes and the Lattice bars are different on the length of the middle bar. Then it is useful if a certain regularity is observed, i.e. the length a slot should then e.g. be twice or nearly twice as large as the length of two successive elongated holes, the grid bars between two shorter oblong holes should be shorter than the webs between a shorter and a longer slot.
  • a prefabricated, continuous profile bar is made of a foam material in the event of fire.
  • the multi-chamber hollow profiles 10 shown in Figures 1 and 2 made of aluminum have a closed outer chamber 11 and a closed inner chamber 12 on by two parallel central webs at a distance from each other 13, 14 are connected. In the illustrated embodiments, the outer sides facing away from one another are still T-shaped profile webs 13 ', 14' stated.
  • the multi-chamber hollow profile 10 shown is in the two Embodiments extruded in one piece.
  • the middle webs 13, 14 are in series, i.e. in same Distances to the outer and inner chambers 11, 12 slots 15 punched, whose lengths are significantly greater than those remaining between the elongated holes Lattice webs 16.
  • the figures show that the elongated holes 15 of the central web 13 around half the length are offset from those of the central web 14. Besides, they are Widths of the elongated holes 15 are significantly smaller than the central webs 13, 14. Since the Elongated holes 15 of both center webs 13, 14 equidistant from the outer and Stand inner chamber 11, 12, is a lattice structure maintaining stability formed because the elongated holes within the elongated holes 15 of each central web 13, 14 act like a space grid.
  • the ratio of the width of each central web 13, 14 to Width of an elongated hole 15 is in the illustrated exemplary embodiment according to the Fig. 1 approx. 3: 1.
  • the length of each elongated hole is 15 for example 200 mm and the average length of each grid web 5 mm. from that it follows that over a length of one meter of the multi-chamber hollow profile 10 five bars with a width of 5 mm are created. This results in 13 for each central web, 14 in total a total length of 50 mm or 5% of the respective length a multi-chamber hollow profile 10.
  • each elongated hole 15 could also be, for example, 125 mm and the middle Length of each grid web 16 be three millimeters. It then results per Meters of the multi-chamber hollow profile 10 fourteen webs with a total length of 42 mm, resulting in a share of 4.2% per running meter of the multi-chamber hollow profile - Based on each central web 13 or 14 - results.
  • the lengths of the elongated holes 15 and Crossbars 16 not the same.
  • an elongated hole 15 with a greater length of e.g. 103 mm two elongated holes 15a with a length of 50 mm each.
  • the length of the Lattice webs 16 would then have to be in the lengths of the elongated holes 15, 15a appropriate ratio will be brought, however, the summed up Overall length preferably not more than 5% of the length of the multi-chamber hollow profile 10 lie.
  • the outer chamber 11 and the inner chamber 12 are shown in FIGS Embodiments rectangular in cross section and with a fire-retardant material strips 17 filled, which form and / or is non-positively fixed in it, so that no parentheses or the like mechanical fasteners are necessary. It can be found on each center bar 13 and 14 one or two profile bars 18 are defined, which extend over the entire Extend length and made of a foam material in the event of fire are.
