Definitions

  • the present invention relates to connection profiles for connecting drywall to ceilings, floors and solid walls.
  • the invention further relates to measures for the realization of fire protection in the field of connection profiles for drywall.
  • Connection profiles for drywall are used to connect the drywall to a connection component, such as a wall. a ceiling, a floor and / or a solid wall used.
  • a connection component such as a wall. a ceiling, a floor and / or a solid wall used.
  • Such a connection profile generally has an approximately U-shaped cross-section, the base surface of which is mounted parallel to the attachment surface of the attachment component, so that its limb surfaces project from the relevant attachment surface.
  • drywall panels such as e.g. Plasterboard, to be fixed.
  • connection profile is attached to the connection component, wherein the drywall panels are attached to the legs of the connection profile at a defined distance from the connection component.
  • sealing of the drywall in the region of a joint between the drywall and the connection component for example by either a suitable sealant is introduced or filled the gap with mineral wool and on the surface with a sealing Layer is provided.
  • a suitable sealant is introduced or filled the gap with mineral wool and on the surface with a sealing Layer.
  • the material in the joint between the drywall and the connection component hinders the movement of the drywall board relatively strongly. In order to achieve sufficient movement absorption, therefore, a relatively large joint width must be selected, which can be sealed only with increased effort.
  • the sealing of the joint with a sealant is an additional step, which can be done only after the assembly of the drywall and also requires a two-sided access to the finished drywall.
  • this approach is prone to error as the user must manually dose the amount of sealing material to adequately seal the joint.
  • the width of the joint must be selected according to the material and properties of the sealant used. In particular, it must be ensured with an expansion of the joint that the sealant adheres sufficiently strong to the ground and can absorb the resulting tensile forces. Otherwise, there is a risk of detachment of the sealant from the connection component or cracking. In the case of a reduction in the joint width, the sealing compound can only be compressed to a limited extent due to its material properties, and there is a risk that it will be pushed out when the joint is dimensioned incorrectly.
  • connection profiles are known in which a fire protection in the form of an intumescent sealing strip is realized on outer surfaces of the leg sections. Due to the thickness of the sealing strip attached drywall on the sealing strip and thus seal the edge region of the drywall from. Since the drywall panels are attached to the leg portions of the connection profile, the thickness of the sealing strip can not be chosen arbitrarily high, otherwise there may be an undesirable kinking / breaking of the drywall panels. Due to the limited thickness of the sealing element whose temperature insulation effect is limited and it comes in case of fire cold side on the Sealing element to a temperature exceeded. In addition, the production of intumescent materials is relatively expensive. In addition, intumescent materials are relatively stiff, so that unevenness of the drywall or the terminal component can be compensated only bad and leaks can occur.
  • connection profile for a drywall known, in which a seal of the joints between drywall and terminal component is done by an intumescent strip.
  • connection profile for a drywall wherein between a wall and the connection profile an intumescent material is introduced, which expands in case of fire and so gets into the joint between the wall and the dry component and seals them. Furthermore, it is provided intumescent material to be arranged in the interior of the U-shaped cross section at a portion of the legs, which adjoins directly to an inner edge between the leg and a base part of the U-shaped connection profile.
  • a protective element for a connection profile for attaching a drywall to a terminal component according to claim 1 and by an arrangement of a connection profile and a protective element and drywall with a connection profile and a protective element according to the independent claims.
  • a distance provided through which a used for fastening the drywall to the terminal component connection profile is accessible from the outside In the event of fire, heat can thus act directly on the material of the connection profile, and it can come on the cold side of the profile surface to a critical temperature increase.
  • a protective element which is attachable to a leg portion of a connection profile and has a plurality of superimposed sheet-metal layers. Between the sheet layers an intumescent element is provided, which expands in case of fire and presses the sheet metal layers apart. In case of fire, the sheet metal layers get such a greater distance from each other, so that the cold side sheet metal layer is pushed away from the heat source. It is thereby achieved that the cold side sheet-metal layer heats up more slowly due to the increased distance from the heat source. Thus, can more reliably, the cold-side sheet-metal layer is prevented from being heated above a firing temperature.
  • the intumescent element of the protective element preferably has an onset intumescence temperature between 130-200 ° C.
  • the protective portions may be connected together at one end to form a V-shape, the intumescent member being provided as an insert member or as a coating inside the V-shape of the protective portions.
  • the protective element can be easily formed with a one-piece sheet metal element.
  • the protection portions may be formed separately from each other and the intumescent member may be formed as an insert member connected to both of the protection portions to hold the protection portions together.
  • one of the protective sections may be connected to a holding section and in particular may be formed integrally therewith, the holding section projecting transversely from the at least one protective section.
  • the protective element can be arranged during assembly between the connection profile and the terminal component, so that when securing the connection profile to the terminal component, the protective element is thereby held.
  • the holding section may be provided on a surface facing away from the protective section with intumescent material, in particular in the form of a coating.
  • intumescent member disposed on a surface of the one protection portion facing the protruding holding portion.
  • the further intumescent element may extend from an inner edge formed between the holding section and the one protective section at least partially over the width of the one protective section towards an end of the one protective section facing away from the holding section.
  • the one protective section may be provided with passage openings in the region of the further intumescent element.
  • the through-openings make it possible, when the material of the further intumescent element expands, to pass through the through-openings between the protective sections, thereby pushing them apart.
  • a protective section of the at least one protective element can be held on at least one of the leg sections via a further intumescent element, in particular by clamping.
  • the protective portions of the protective element may be arranged between a joint formed between the drywall plate and the connecting component and the leg portion.
  • the intumescent element can be arranged between a gap formed between the drywall and the connection component and the leg section.
  • a use of the above protective element for mounting a drywall by means of a connection profile is provided, so that the protective element between a drywall and a leg portion of the connection profile in the region of a joint between the drywall and a terminal component is arranged.

  • a refractory material which may consist of a sheet metal material, in particular of a metallic material, which has a high fire resistance.
  • the protective element 10 has two sheet metal layers, between which intumescent material is arranged. In case of fire, an increase in volume of the intumescent material takes place, which presses the sheet metal layers apart and thus increases the distance between the sheet metal layers. As a result, the cold-side sheet-metal layer is pushed away from the heat source and the temperature can be kept lower there.
  • the protective element 10 has an integral sheet metal element 11 which (with respect to its cross section) comprises a holding section 11a, a first protective section 11b and a second protective section 11c.
