Definitions

  • the invention relates to a fire protection door for closing an opening of a traffic tunnel, comprising a door leaf which is formed from a thermally insulating inner body and a casing which encloses the inner body at least in the area of the surfaces of the inner body facing the door leaf outer surfaces, according to the preamble of claim 1 .
  • Fire protection doors have the task of securing openings in fire-retardant or fire-resistant walls against the passage of fire. Fire protection doors that are used in traffic tunnels usually close escape tunnels or technical rooms opposite the tunnel tube and thus protect people fleeing and technical installations in the event of a fire. In addition to the high temperatures caused by a possible fire, corresponding fire protection doors must also have suction and
  • fire protection doors are known from the prior art which have a solid metal body which is clad with fire protection panels.
  • DE 2657141 A1 discloses, for example, a fire protection door leaf comprising a metal frame and cover plates, an inner area of the metal frame being foamed with aerated concrete.
  • a disadvantage of the fire protection doors known from the prior art is that the high loads that occur in traffic tunnels due to exhaust gases and aggressive mountain water in connection with high humidity cause corrosion, which is why the fire protection door leaves are usually made of stainless steels. Such steels are complex to process, prone to fatigue fractures and expensive. They also have a high thermal expansion, which has a disadvantageous effect on the dimensional stability of the fire door leaf in the event of a fire. Furthermore, the fire protection door is heavy when using stainless steels and can often only be opened manually with great effort.
  • Claim 1 relates to a fire protection door for closing an opening of a traffic tunnel comprising a door leaf which is formed from a thermally insulating inner body and a casing which encloses the inner body at least in the area of the surfaces of the inner body facing the door leaf outer surfaces.
  • the casing is made of a mineral cast material, and that a reinforcement designed in the form of a grid is embedded in the casing.
  • a mineral cast material is distinguished in comparison to metallic materials low material costs, easy processability, low thermal expansion, high resistance to environmental influences and - compared to steel, for example - lower mass.
  • the door leaf of the fire protection door is reinforced with a grid-shaped reinforcement, since a mineral cast material tends to form cracks when subjected to tensile or bending stresses.
  • the lattice-shaped reinforcement is embedded in the casing on one side or on both sides of the inner body and absorbs both tensile and compressive loads in the longitudinal and transverse directions of the door leaf.
  • the door leaf outer surfaces are those surfaces of the door leaf which, in the closed state, extend over the wall opening closed by the door leaf and are generally perpendicular to the direction of passage.
  • the lattice-shaped reinforcement is encased in the cast material of the casing, which means that a high level of structural stability and an optimal connection to the cast material can be achieved.
  • the lattice-shaped design also enables the fire protection door according to the invention to be produced in a simple manner, as will be explained in more detail below.
  • the fire protection door according to the invention is also characterized by a high level of resistance to environmental influences and to heat.
  • the thermally insulating property mentioned with regard to the inner body means in the present context that the inner body in any case has a higher thermal insulating capacity than the casing.
  • the structure provided according to the invention thus aims to ensure the thermally insulating properties of the fire door primarily with the help of the inner body, and the structural stability primarily with the help of the sheathing, although the sheathing also contributes to thermal insulation and the inner body to structural stability.
  • the fire protection door according to the invention can be compared to conventional designs significantly reduced mass easier to open manually.
  • the lattice-shaped reinforcement is made from glass fibers and / or carbon fibers.
  • Carbon fibers in particular, have a high tensile strength, so that less reinforcement material is required when using a reinforcement made from carbon fibers with the same tensile and compressive load properties of the door leaf cladding.
  • the mineral cast material of the casing is an epoxy resin-bound mineral cast or a cement-bound high-performance concrete (Ultra High Performance Concrete, UHPC).
  • UHPC is characterized by its particularly high strength.
  • UHPC in connection with the lattice-shaped reinforcement can absorb not only high compressive forces, but also high tensile forces.
  • the proposed version of the ultra-high-strength, reinforced concrete is therefore particularly resistant to compression and tension.
  • the inner body is made of expanded concrete. With the help of expanded concrete, the inner body can be cast as a one-piece body. According to a further embodiment it is provided that the inner body is made of rock wool, which is held within a plurality of frame parts, each running parallel to one another horizontally and vertically. The horizontal and vertical frame parts delimit cuboid areas in which the rock wool is received, whereby the frame parts can also be provided with reinforcement.
  • rock wool and expanded concrete are excellent non-combustible insulation materials and have high thermal stability and high acoustic insulation properties. Furthermore, rock wool is biosoluble in the human lungs and therefore does not pose a health risk to people.
  • At least one suspension element is arranged in an upper region of the door leaf, which is fastened to the inner body and / or the casing and has a section designed like a toothed strip that engages in the reinforcement designed in the form of a grid.
  • the at least one suspension element is used to movably fasten the fire protection door leaf according to the invention in a wall opening.
  • the fire protection door leaf can be movably attached with the aid of the suspension element, for example, to a frame surrounding the wall opening of the traffic tunnel at least in sections.
  • the section designed like a toothed strip increases the security of this connection with the aid of a form fit, in that the teeth of the toothed strip-like section engage in the reinforcement designed in the form of a lattice.
  • the section designed like a toothed strip also facilitates the production of the fire protection door panel according to the invention, since the reinforcement, which is designed in the form of a grid, cannot slip during the pouring of the concrete for the production of the casing.
  • the fire door according to the invention can be produced simply with the help of a formwork into which the inner body with the reinforcement arranged on one or both sides and the suspension elements are inserted, and which is subsequently poured with concrete. After the concrete has hardened, the formwork can be removed.
  • an additional rod-shaped reinforcement is arranged in the casing in an upper area of the door leaf.
  • This rod-shaped reinforcement provides additional stiffening to absorb these loads.
  • at least one guide element for guiding a sliding movement directed parallel to the plane of the door leaf is arranged in a lower region of the door leaf.
  • the at least one guide element can be designed, for example, as a guide roller.
  • the casing has at least one outgassing opening which extends from one of the door leaf outer surfaces to the thermally insulating inner body.
  • the outgassing opening enables possible outgassing of the door leaf inner body, which can form due to the high temperatures, to escape.
  • the at least one outgassing opening be closed with a closure material which has a melting temperature that can only be reached in the event of fire. In the event of fire, the low-melting sealing material melts and the outgassing opening is opened for gases to escape.

  • FIG. 1 shows a front view of a fire protection door 1 according to the invention, part of an upper region 10 of the fire protection door 1 according to the invention being cut away.
  • the fire protection door 1 according to the invention comprises a door leaf which is formed from a thermally insulating inner body 3 and a casing 2, the casing 2 enclosing the inner body 3 at least in the area of the surfaces of the inner body 3 facing the door leaf outer surfaces 4, 5.
  • the door leaf outer surfaces 4, 5 each face the surroundings of the fire protection door 1 according to the invention.

  • This structure of the fire protection door 1 according to the invention can be seen in particular in FIGS. 2 and 3, FIG. 2 showing a sectional view of the fire protection door 1 according to the invention according to the section line AA drawn in FIG. 1, and FIG. 3 an axonometric view of the upper area 10 shows the fire door 1 according to the invention, a part being cut freely.
