Definitions

  • the invention relates to a sealing device for a joint, in particular a movement joint, in the preamble of claim 1 explained type.
  • Such a sealing device for a joint is known from EP 1 589 157 known.
  • the known joint contains a sealing device for the joint, which comprises a cover plate, which covers the joint on one side and is provided with a movement reserve to allow relative movements of the two adjacent to the joint components.
  • the sealing device further contains at least one layer of a web or mat-shaped fire protection material, with which the cover plate is deposited in the joint cavity.
  • the sheet or mat fire protection material is coated with expandable material.
  • the sealing device contains mat-shaped, inflatable fire protection material of the known type, which is inserted in one or more layers in the joint and bonded to the opposite boundary surfaces of the components.
  • the fire protection material covers the joint on both sides and forms the outer surface of the joint.
  • the fire protection material is laid so that it sags with its own weight, so that a certain reserve of movement for a movement of the components is created.
  • the fire protection material may be laminated with a heat-resistant material such as a metal foil.
  • the metal foil is naturally on the bonded side, ie on at least one outwardly facing side of the joint. However, metal is heat-conducting.
  • the heat is thus conducted directly to the adhesive bond.
  • the heat generated during the fire is even conducted to the back of the components when the metal foil-laminated fire protection material fills the entire joint in a more or less closed circle.
  • the film is provided on one side with a slot which is to interrupt the heat conduction. However, this slot also provides direct access to the interior of the joint.
  • the known sealing device is designed so that it has to fill the entire joint. This is particularly disadvantageous where existing joints must be retrofitted for fire protection.
  • the known sealing devices require that for this purpose, the entire original Fugenver spallung is scraped and refilled by the known sealing device. This is extremely expensive.
  • Another joint with a sealing device made of fire protection material is from the EP 730 695 B1 known.
  • the sealing means of this joint consists of a readily compressible tube made of a composition consisting mainly of a mixture of an elastomeric material and a bulking material. Again, it is necessary that the entire gap must be cleared empty, if the joint must be retrofitted for fire protection.
  • the invention has for its object to provide a joint and a sealing device for this, the fire protection technology is extremely effective and easy to install.
  • the inventive use of a two-piece cover plate with movement reserve, which is coated with fire protection material the problem of fixing the fire protection material in the joint is solved in a structurally simple manner, without having to resort to an adhesive application over the entire thickness of the components, and on the other hand created very effective fire protection, in which there is no risk that is transmitted by the materials of the sealing device itself heat to the opposite side of the components.
  • the sealing device may be relatively thin-walled, so that it has only a small footprint in a joint, and further provides through the cover a solid protection against damage in normal use, ie not in case of fire, without this massive protection in case of fire for destruction or Damage to the sealing device could result because the cover plate has a reserve of movement.
  • a fire protection material optionally Dämm Mrs Kunststoffmaschinen or Ablationsbe lamb GmbH in question.
  • the reaction takes place at a temperature of around 200 ° C so that the material increases in volume, forming an insulating layer.
  • the thickness of the forming insulating layer varies from material to material.
  • the temperature reduction is carried out by a chemical reaction, which leads to an embrittlement or hardening (ceramifying) of the material and this requires the supply of heat, just the fire.
  • the cover plate can extend beyond the gap without affecting the function and be fastened to the components outside the joint. In this way, the space required inside the joint is further reduced.
  • cover plate is also coated with fire protection material outside the joint, since this extends the fire protection beyond the joint, and improves the sealing effect.
  • the fire protection coating may have a greater thickness inside the joint than outside the joint.
  • the fire protection material can, where necessary or desired, be applied in multiple layers, which may be necessary in particular in the interior of the joint.
  • the cover plate can preferably be attached to the components with mechanical fastening means, such as screws, rivets, anchors or dowels, which further facilitates the assembly.
  • the cover plate consists of at least two parts which are connected to each other via a movement connection, whereby the movement reserve of the cover plate is realized.
  • the movement connection can be additionally sealed by inserted fire protection material.
  • An additional reserve of movement can also be achieved in the region of the fastening means of the cover plate, for example by making holes for mechanical fastening means such as screws or bolts or rivets larger than would correspond to the diameter of the fastening means.
  • An additional reserve of movement of the cover plate can also be realized by a stretchable design of the cover plate, which is preferably done by molded into the cover plate grooves or waves that straighten under the action of tensile forces.

  • the application thickness of the intumescent agent on the support should be about 1500 g / m 2 (wet application) of the support surface. The amount applied depends on the thickness to be achieved after foaming, which in turn depends on the fire protection specifications and the materials used.
