Definitions

  • the invention relates to a revision flap for reversibly closing a Opening in a wall and ceiling covering with a frame, one removable panel and a flame-resistant plate that the Essentially fills the opening. Furthermore, the invention relates to a Inspection flap, in which an air gap is sealed in such a way that a Flame penetration or smoke penetration is prevented.
  • the fire protection regulations of buildings stipulate that the walls of Fire sections or shaft walls or suspended ceilings with fire retardant or at least high temperature and / or flame resistant Materials must be covered. These linings are usually mats or sheets of refractory fibrous or foamed materials. There according to the regulations, the entire cladding must be flame-resistant this also applies to the inspection flaps.
  • the inspection flaps known from practice are placed in openings in wall, Shaft or ceiling cladding used and if necessary Revision opened by opening or removing the flap. After Dismantling the inspection flaps are usually placed next to the opening.
  • the flame-resistant plate is placed on a substructure of the ceiling, see above that they are removed from the inspection flap and opened to the side must be asked. Similarly, before closing the inspection flap, the flame-resistant plate in turn be placed on the substructure before it can be pushed back into the opening in the ceiling cladding.
  • the Opening and reclosing the inspection flaps is therefore difficult and time consuming and it cannot be ruled out that the flame retardant before The inspection flap does not close or does not close correctly on the panel flap is attached.
  • such a flame retardant is for Wall coverings unsuitable because it is due to the inspection flap Gravity doesn't hold.
  • the tightness of the opening is in even after the inspection flap has been closed usually not guaranteed.
  • the cladding in the is kept essentially flame and gas tight. Only through such tightness is ensures that one created behind the wall and ceiling cladding Fire or smoldering no unlimited amounts of oxygen added become.
  • the flames and the Smoke not unobstructed in the area of everyone closed with an inspection flap Emerge from the opening. It is precisely through the smoke outlet that toxic gases can be released large areas of a building complex are distributed.
  • an inspection flap has thus been made available which can be closed reversibly and in which the flame-resistant plate with the Cladding panel is permanently connected. So when you open the revision flap according to the invention separating the flame-resistant plate from the cladding panel is no longer necessary and no longer possible.
  • An installation of the Inspection flap according to the invention is thus also in the wall coverings of Buildings possible.
  • the inspection flap according to the invention also ensures a great security against the penetration of flames through the wall and Ceiling cladding and against the escape of smoke or other toxic Gases.
  • the inspection flap according to the invention is also simple in construction and therefore easy and inexpensive to manufacture. An additional advantage is that for Ceilings and wall structures used the same fire dampers can be.
  • a wall and ceiling covering in the sense of the invention can be made of any kind rigid materials can be existing cladding.
  • Such wall and Ceiling coverings are preferably made of a plaster material, such as the one below the name GKF is known. These materials are usually in shape standardized panels of different thicknesses, but with the same length and width dimensions in front.
  • the wall claddings are made by putting these standard panels together manufactured.
  • the wall and ceiling cladding offer the possibility Supply lines also flexible in existing buildings and to the to suit individual needs without laying the walls of the building to have to pry open. There is also the possibility of two layers of such Moving in wall cladding as an independent partition and thus larger Divide rooms individually. The supply lines are in one Fall between the layers of wall cladding.
  • these panels have openings at regular intervals that serve to hide the hidden supply lines, be it for energy, Water or air.
  • Inspection flaps are reversibly closed.
  • the inspection flaps usually face a frame, preferably a metallic frame, on the opening of the Bordered wall or ceiling cladding.
  • the Cladding panel can be closed reversibly, preferably with the help of Frame hinges preferably hung hinged.
  • the Cladding panel is preferably made of the same material from which the remaining wall and ceiling cladding is manufactured, usually GKF.
  • the Cladding panel essentially hides the opening in the wall or Ceiling panels.
  • the cladding panel is one made of a flame resistant Material existing additional plate permanently connected to the Cladding panel protects against the effects of flames or heat or at least supported.
  • the flame-resistant material preferably covers the entire opening.
  • the flame-resistant plate is a preferred one Embodiment of the invention made of a fibrous or foamed material.
  • the flame-resistant plate is in an advantageous embodiment of the invention from enclosed in a stabilizing frame. As a result, the Dimensional stability of the flame-resistant plate is permanently guaranteed.
  • the permanent connection between the cladding panel and the flame resistant plate can be in any conceivable way, for example by Glue, done.
  • the connection by using suitable push-through means are a particularly preferred embodiment of the invention Screws through the cladding panel into the flame resistant panel be screwed in.
  • the permanent connection in an extremely preferred embodiment, in that the screws through the Connection plate through into the frame surrounding the flame-resistant plate or in parts connected to this frame. This enables to use flame-resistant materials, for example, because of their The structure is not suitable for screwing.
  • Another object of the present invention is an inspection flap, at which is a flame breakthrough through air gap in the area of the inspection flap, which too inevitably occur with a closed inspection flap, at least is reduced.
  • this is achieved by attaching at least two means arranged one behind the other, which start at a certain temperature
  • Enlarging volumes greatly enables.
  • the increase in volume can be done by The agent swells or foams.
  • the foaming material is designed in such a way that after reaching it the temperature required for foaming very quickly and very strongly, particularly preferably foams up to 7 times its original volume and the foaming process at higher temperatures for a certain time, preferably lasts more than one hour, particularly preferably at least 90 min.
  • the rapid foaming preferably takes place at at least about 100 ° C. and that Continue foaming at temperatures of at least 150 ° C.
  • the air gap is sealed by a swelling and a foaming agent.
  • the volume jump of both means also at different temperatures, which is based on the Flame source preferably foams first agent and the second middle itself expands and the first agent starts preferably at a lower temperature as the second means.
  • the seal can be used depending on the range of Opening temperatures occur. It is also guaranteed that at particularly high temperatures nevertheless achieved the greatest possible sealing effect can be. Furthermore, this sealing arrangement is an additional one Hedging given. If the flames penetrate the first seal, there is another fuse that only starts.
  • a first means between the flame-resistant plate and the frame surrounding it appropriate.
  • a second means is Invention between the frame surrounding the opening and the Cladding panel attached.
  • each air gap is opposed to one the closing direction of the inspection flap prestressed seal, preferably a Flat gasket, covered.
  • the seal is in the area of the frame of the opening the wall and / or ceiling cladding mounted and protrudes into the opening.
  • At the The cladding panel or a flame protection located thereon is closed pressed against the seal.
  • Air gaps covered with particularly simple means and when closing the Inspection flap a positive connection between the seal and the wall and Ensures ceiling cladding in the area of the air gap. This form fit reduces the escape of toxic gases from the fire area and the ingress of Air and thus oxygen to the fire area.
  • the flat gasket consists of a preferably heat-resistant material, preferably metal, the for its part preferably has a deformable lip which between the Seal and the flap is arranged and due to the bias is squeezed.
  • the lip improves the form fit and thus the Sealing effect of the seal.
  • FIG. 1 shows the top view of an inspection flap 1 according to the invention.
  • the flame-resistant plate 4 is enclosed by a frame 8 which has reinforcements 10 in the region of two adjacent corners.
  • the flame-resistant plate essentially fills the opening in the wall or ceiling covering.
  • FIG. 2 shows a side view of the inspection flap 1 cut along the line AA from FIG. 1.
  • the inspection flap 1 has on its outer side 14 two identical cladding panels 3 lying one on top of the other.
  • a flame-resistant plate 4 is arranged on the cladding panels 3.
  • the flame-resistant plate 4 is surrounded by the frame 8.
  • FIG. 3 shows an enlarged illustration of the detail designated X in FIG. 2.
  • the trim panels 3 are surrounded by a frame 12 which has a plurality of projections 15 which form a positive and non-positive connection with the trim panels.
  • the person skilled in the art recognizes that a cladding panel would also be sufficient for the functioning of the inspection flap according to the invention.
  • the flame-resistant plate 4 is irreversibly connected to the upper of the two cladding plates.
  • the frame 2 encloses the opening in the wall and ceiling cladding (not shown). The inspection flap can be closed with the lock.
  • a sealant 6 is attached, which does not completely seal the air gap below a defined temperature, but foams strongly above this temperature, so that the entire air gap 5 seals around the flame-resistant plate 4 becomes.
  • the sealant is a ROKU strip from the Kuhn company.
  • a further sealant 7 which expands greatly at a preferably higher temperature than the means 6 and thus the air gap 5 seals around flame penetration in the area of means 6.
  • FIG. 4 shows an enlarged representation of a partial area of the inspection flap 1 according to the invention, here with a metal flat gasket 9 covering the air gap 5.
  • the flat seal 9 is connected to the frame 8 in a prestressed manner such that its end 17 is pressed onto the flame-resistant plate 4 in a non-positive and positive manner.
  • a compressible, in a preferred, but not necessary embodiment, temperature-resistant rubber seal is arranged around the end 17, which improves the positive connection between the seal 9 and the flame-resistant plate 4. Sealing of the air gap 5 is thus achieved even below the temperatures at which the sealant 6 applied between the frame 8 and the flame-resistant plate 4 or the sealant 7 applied between the frame 2 and the frame 12 encompassing the cladding panels experience a jump in volume. Due to the preload, the flat gasket seals both under or overpressure.
