Definitions

  • the invention relates to a fire protection door made of asbestos-silicate material with a frame and with cover plates which cover the frame and the filling plate lying between them, the upper and the lateral parts of the frame and the cover plates being covered by two fire protection strips which are covered by a good heat-conducting material strips are separated.
  • fire protection doors are known. These often consist of a steel frame and steel plates. These fire protection doors are very heavy, their dimensions cannot be changed afterwards and they no longer meet the newer requirements for fire protection.
  • a fire protection door of the type mentioned at the outset is known, in which the two fire protection strips are separated from one another by the highly heat-conducting material strip.
  • the good heat-conducting material strip ensures that the heat is distributed evenly, so that the fire protection strips foam up evenly.
  • the second fire protection strip foams at the same time as the first. (FR - A 1 517 444).
  • a fire protection door made of metal has become known, in which several fire protection strips are arranged on the outside of the metal frame designed as a hollow profile, between which there is a metal fastening plate. These parts are held by a screw that is screwed into and through the metal frame. Another fire protection strip is provided between the metal frame and the filling, which is as wide as the metal frame (DE-OS 25 25 309).
  • the invention is based on the object of creating a fire door of the type mentioned which meets the increased requirements of fire protection, in particular the downtimes in the event of a fire, and is also simple in construction and also allows its dimensions to be adapted on the construction site.
  • This object is basically achieved in that a frame strip is arranged between the fire protection strip resting on the frame and the material strip.
  • the two fire protection strips are not only separated by the good heat-conducting material strip but also by the frame strip. It is hereby achieved that the fire protection strip, which is in direct contact with the highly heat-conducting material strip, first foams. Only later, when the heat development continues and increases, does the second fire protection strip foam up. The expansion of the two fire protection strips takes place over time. This significantly extends the service life of the fire protection door in the event of a fire. Tests have shown that the new, stricter fire protection requirements are met for over 100 minutes. This surpasses previous fire protection doors. Through the interaction of the two fire protection strips, they exert correspondingly laterally directed high compressive forces on the door, which counteracts arching of the door. The fire protection strips, including those that take effect second, extend practically across the entire width of the door leaf frame.
  • the fire protection strips are basically known products for this purpose.
  • This product consists of a core of essentially water-containing sodium silicate.
  • the core layer also contains small amounts of organic additives as well as glass fibers and a glass fabric or a wire mesh.
  • a double-sided epoxy resin layer protects the core against atmospheric influences, especially carbon dioxide. They can be plastically deformed in a temperature range between 60 and 100 ° C. They increase their volume above 100 ° C, especially by foaming. The result is an incombustible, fine-pored, crack-resistant, pressure-resistant and heat-resistant foam layer, the melting range of which is over 900 ° C. When foaming occurs, a relatively high pressure is created.
  • the fire door can be designed such that the filler plate is made of asbestos silicate material of lower density than the cover plates. As a result, the weight of the door is reduced without losing the protective effect.
  • the heat-conducting material can advantageously be an aluminum strip.
  • a covering can be made with different wood materials.
  • the covering of the fire protection strips in the area of the sides and in the upper area by wooden strips enables adaptation to the construction site by planing or the like.
  • a fire protection strip is not provided on the lower edge, since for known reasons the risk of striking through in the event of a fire is very much lower . In this area, particularly due to the lack of a metal frame or the like, machining and adaptation to different dimensions is very easy and possible in a large area.
  • a steel strip can advantageously be fastened between the filler plate and the frame of the hinges, into which a thread for a corresponding threaded screw for fastening the hinge is then cut. It is also possible to attach the components additionally or solely by means of special screws, on the thread of which a coil spring is seated. After the threaded hole has been drilled, this helical spring is fastened in the threaded hole the first time it is screwed in, ie it remains in the threaded hole when the screw is loosened and thus forms the thread in the material which is normally very poorly suited for this purpose.
  • the fire door shown in the drawing consists of a frame 2 and frame strips 4 made of asbestos-silicate material.
  • this frame is a filler plate 1, which is covered by cover plates 3.
  • the asbestos-silicate material of the filling plate preferably has a lower density.
  • a fire protection strip 5 of the type defined at the outset is located on the outside of the frame strip 4 in the region of the upper edge and in the lateral region, an aluminum strip 7 being provided between the fire protection strip 5 and the frame strip 4.
  • a fire protection strip 6 is also provided, but without an additional aluminum strip. Outside, the fire protection strip 5 is covered by a wooden strip 8. The entire structure is protected on the outer surfaces by veneered plywood 9.
  • the asbestos-silicate material of plates 1 and 3 is glued by a component adhesive 12.
  • screws 13 are provided for attachment.
  • the veneered plywood 9 is glued on by a contact adhesive 11.
  • the fire protection strips are also attached by gluing.
  • the hinges are fastened by threaded screws 15, the nut thread of which is formed in a strip steel 10.
  • This steel strip 10 lies between the frame 2 and the filler plate 1 (see also FIG. 2).
  • the corresponding hole is drilled into the area of the steel strip.
  • a thread can then be cut into the steel strip into which the screw can be removably screwed and ensures secure fastening.
  • screws 16 can be provided for the hinge and in particular also for fastening the door lock, not shown, which are equipped with a separately designed coil spring 17 adapted to the thread. This coil spring is self-tapping and remains in the asbestos-silicate material when the screw is first fastened and practically represents the nut thread for the screw.
  • an asbestos-silicate material with a density of 192 kg / m 3 was chosen for the filling material.
  • the cover plates and frame strips had a density of 960 kg / m 3 , whereas the density of the frame was 2 720 kg / m 3 . This is only one embodiment.
  • FIG. 2 is a simplified illustration in which the fire protection strips and the frame strip 4 are not shown.
