Definitions

  • the invention relates to a fire blanket for escape routes in buildings according to the preamble of claim 1 protection.
  • a fire blanket of the type mentioned above, which serves to delineate an escape route from an area for cable and pipe guide and the like in a building is known from DE 92 05 288 U1.
  • Another fire blanket is known from DE 84 37 592 U1. This comprises several, juxtaposed, the width of the escape route spanning ceiling segments that rest on horizontally extending legs of attached to walls of the escape route, metallic L-profiles.
  • the ceiling segments are formed from a combination of metal and plasterboard, the metallic surfaces are arranged on the visible side and the plasterboard facing away from view.
  • This fire-resistant ceiling complies with the standard of fire protection class F30 of DIN 4102, Part 1.
  • the invention is therefore the object of the segments of a fire blanket of the type mentioned while retaining their benefits to go on to further that they can be tailored easily at the installation site.
  • the ceiling segments are made of lightly reinforced lightweight concrete, preferably cellular concrete.
  • This requirement leads to a fairly homogeneous basic structure of each ceiling segment, in which both the proposed reinforcement and the concrete takes over carrying function and in which a cut at the installation site with a saw readily possible because the surface of the ceiling segment even after a cut on site all visually satisfies requirements.
  • this construction offers a fire protection on both sides, since the metallic reinforcement is regularly arranged centrally in the ceiling segment. This eventually leads to this fire blanket according to the invention fulfilling the F90 standard for fire resistance.
  • the fire protection ceiling for escape routes in buildings illustrated in FIGS. 1 to 9 always comprises a plurality of ceiling segments 1 arranged side by side and spanning the width of the escape route, which rest on horizontally extending legs of L-profiles 2 fastened to walls of the escape route.
  • the metallic L-profiles 2 are preferably made of steel, in particular of high temperature resistant steel.
  • the L-profiles 2 a support area 4 for the ceiling segments 1, which is preferably not wider than 50 mm formed seen transversely to the L-profile.
  • the L-profiles 2 are fastened with screws on walls of the escape route. Of course, other attachment methods are also possible.
  • the ceiling segments 1 are made of lightweight concrete, preferably cellular concrete, provided with an internal reinforcement 3.
  • the lightweight concrete or aerated concrete
  • the lightweight concrete is provided with additives such as Styrofoam®, glass foam, vermiculite or perlite.
  • aerated concrete belongs to the group of lightweight concretes and is a highly heat-insulating solid construction material which, due to its closed-cell pore structure, can take over static as well as structural-physical properties - as a rule without additional measures and supplementary building materials.
  • the aerated concrete owes its properties to the raw materials used, the resource-saving production process and, above all, to the air, because up to 80% of its volume consists of this massive building material of air and only too much 20% solids
  • quartz sand, cement and / or lime as binder and water
  • the aerated concrete obtains its characteristic properties by steam hardening in an autoclave.
  • Among the outstanding properties of aerated concrete is a high strength at a relatively low density.
  • aerated concrete In combination with the low bulk density, aerated concrete is a solid building material with excellent thermal insulation. In addition there is a standard sound insulation. Ultimately, aerated concrete can only be characterized by the sum of its positive properties. Aerated concrete is suitable for the construction and modernization of detached and semi-detached houses, for multi-storey housing construction and the construction of commercial buildings. "
  • the ceiling segments 1 have a maximum width of 3 m and a thickness between 50 mm and 100 mm.
  • the inner reinforcement 3 is formed of metal and preferably arranged in a grid or net-like evenly distributed in lightweight concrete.
  • the ceiling segments 1 at least escape route side either funiert, painted, plastered or coated with a laminate. This leads to a visually appealing design, but still allows a processing of the ceiling segments 1 on site during assembly of the fire blanket.
  • the L-profiles 2 are provided with a lacquer layer 5, which is preferably applied on the escape path side.
  • the L-profiles 2 are coated with an intumescent layer-forming agent 6 preferably applied to the escape path, preferably expanded graphite. This requirement ensures a tight seal between wall and ceiling segment in case of fire.
  • insulating layer formers 11, preferably expandable graphite, are arranged on the ceiling segments 1 L or T profile side.
  • an approximately segment wide (preferably between 300 mm and 600 mm) L-profile 2 is arranged with at least one on a wall of the escape route by vertical displacement and detachable connection element 10. This is in a conventional manner from an opening in the angle plate, which is narrower in a first region and larger in a second region than a screw head.
  • the ceiling segments 1 can therefore be lifted over the L-profiles over the area at the suspended, segment-wide L-profile and placed. The last inserted ceiling segment 1 is then fastened with the segment-wide L-profile.
  • T-profiles 7 are arranged transversely to the L-profiles between them, wherein the horizontal part of the T-profiles 7 extends on the escape path side (that is arranged as an inverted T).
  • a particularly preferred embodiment of the T-sections 7 consists in that its vertical part preferably has edge sections 8 which are extended on both sides and bear on the support areas 4 of the L-profiles 2. This proviso results in the escape path side a smooth-surfaced, visually appealing conclusion. Since the T-profiles 7 do not have a supporting function due to the inner reinforcement of the ceiling segments 1, it is furthermore advantageously provided that these are formed from aluminum.
  • a seal 9 is optionally arranged between the L-profiles 2 and / or the T-profiles 7 and the ceiling segments 1.
  • this fire blanket consists of a ceiling segment made of lightweight concrete, which rests on mounted on the stipulatewegassin L-profiles.
  • a facing the building ceiling edge 12 is provided at the segment-side end of the L-profile 2. This is, for example, as shown, designed as a fold of the L-profile 2 itself.
  • metallic profiles 13 are provided on the ceiling segments 1, which have protrusions 14 facing the L-profiles 2.
  • These projections 14 are hook-shaped and have with their free ends at a distance from each other, which in particular allows a horizontal displaceability of the ceiling segment 1 to the L-profiles 2 arranged on both sides.
  • the hook-shaped projections 14 are formed in the facing the building ceiling edges 12 are hooked.
  • these provisos allow the ceiling segment 1 to be pushed to the left after lifting.
  • the in this way the L-profile no longer engaging behind end of the hook-shaped projection 14 can now be moved together with the entire ceiling segment 1 on the L-profile 2 in a pivoting down. Since on the other side of the supernatant 14 is hook-shaped, this can be hung on the edge 12 of the L-profile, so that the position shown in Figure 9 results.
  • this construction can of course also be used to advantage in the assembly of the fire blanket to first hang the ceiling segments on one side and then to pivot in their final position.
  • a horizontally extending leg 15 is also provided on the building ceiling facing end of the L-profile 2.
  • a gap between ceiling segment 1 and L-profile 2 projecting, at least fire-retardant plate member 16 is arranged on the leg 15.
  • Smoke-proofing is ensured by a smoke seal 17, preferably a compression belt, arranged between the ceiling segment 1 and the plate element 16.
