Definitions

  • the invention relates to a building joint between two components with sealing tape sealingly arranged in the joint for sealing the joint between the two components, in particular a frame profile and a wall portion, wherein the sealing strip has a foam body made of a foamable after compression foam material, wherein the foam body two opposite broad sides for sealing engagement with the two components and two connecting them narrow sides, of which a room inside and the other room outside can be arranged.
  • the joint seal is often constructed of different functional zones.
  • an area of the joint spaced from the joint opening towards the interior of the joint can be sealed with a foam sealing tape or a local foam such as PU foam, a joint area facing the joint opening, which can also be the area of the joint visible on the inside or outside of the joint, in this case as well a bonding sealant such as a sealant be provided.
  • sealants are applied locally from a container such as a tube or cartridge and introduced directly into the joint.
  • Such seal assemblies usually consist of different zones or have different sealing elements for Seal the joint over its entire depth.
  • a joint cord (usually round cord) is often additionally introduced into the joint, so that the joint facing towards the joint opening Area is arched towards the joint opening.
  • pocket-shaped depressions of the joint in the form of gussets form at the contact area of the sealing strip to the joint wall, into which the sealing compound can penetrate. This results in an enlarged contact surface with respect to the joint wall and a stretching area with lower material thickness in the middle, so that tensile stresses are more easily absorbed within the sealant, for example in temperature fluctuations and the adhesive bond of the sealant is relieved of strain with the two components. Cracks with the risk of moisture penetrating between the sealant and the two components are thus reduced.
  • the EP 1 959 065 A1 as well as the DE 20 2006 020 097 U1 describe sealing strips for sealing joints, wherein the respective foam strip of the sealing strip is surrounded by a réelleschi romantic film wrapping.
  • the WO 94/20701 describes a joint sealing strip, which has zones of different impregnation, so that shortly after cancellation of the compression, a profiling of the resulting in returning sealing tape.
  • the US 3 119 204 A discloses the features of the preamble of claim 1.
  • the invention has for its object to provide a production technology easily manufacturable and easy to handle sealing system, which allows easy insertion of a plastic, setting sealant in the joint to form a medium strain range of the same.
  • the shape of the foam body can be varied or adjusted without, for example, a material processing of the foam body is required.
  • the sudstellblock ists Fisch the blocking element on this opposite narrow body side can be virtually zero.
  • the introduction of an additional joint tape is thereby unnecessary.
  • the sealing strip also performs other functions of the joint seal, such as a thermal insulation function, possibly setting the water vapor diffusion resistance in the middle and evt. At the same time space outside joint area, etc. ..
  • the sealing strip can be introduced as a profile in the joint.
  • the reset blocking effect of the blocking element on the respective narrow side of the body thus results in comparison with the body without reset blocking element.
  • the completely freely recessed body with remindstellblock istselement therefore has a different shape, in particular other cross-sectional shape, on than the otherwise identical body without remindstellblock istselement in completely free relaxed Zusatnd.
  • the reset-blocked body region is forcibly maintained at a certain degree of compression by the reset blocking member, unlike the non-restrained body portion which is not compressed when the body is fully recovered outside the joint.
  • the (certain) degree of compression of the restrained block body region thus causes the foam material of the body to have a higher density and lower air permeability with the body fully recessed outside the joint than the foam material of the non-return blocked body region (eg, without the return blocking element).
  • the reset blockage is thus reset-lockingly attached to the body when the respective body region is converted into a compression state, so that this compression state is maintained by attaching the remindstellblock istsimplantations on the body or at least not completely lifted even with complete relaxation of the body.
  • the foam body material in the area of reset blocking and in the area without reset blocking can thus be the same, taking into account the different degree of compression of the reset-blocked or non-reset-blocked body areas.
  • the sealing strip is thus produced from a homogeneous, one-piece sealing strip by attaching the remind einsblocktechniks institutes on a compressed body region and remindstellblocktechnik this area narrow side. From a rectangular body is thus obtained by the remindstellblock réelle a non-rectangular body, each in a completely free relaxed state.
  • the sealant may be paintable with a paint or the like coating material.
  • the reset blocking element preferably extends over a region of the narrow side of the body, so that even when the sealing tape is arranged in a joint in which the foam body is thus compressed, a profiling of the foam body results due to the blocking element. This can be effected in particular by the fact that the lateral extent of the blocking element (expansion in the direction broadside broadside) is smaller than the joint width, so that the body can extend beyond the extent of the blocking element.
  • the "broad side” of the sealing strip is understood to mean the sides of the band that can be laid on or laid onto the two components, in particular the frame component and soffit.
  • One or both of the broad sides are equipped with a fastening means for attachment to one of the sealing surfaces.
  • the attachment means may comprise an adhesive layer, e.g. in the form of a double-sided adhesive tape.
  • the ratio of the width of the sealing strip broad side to the width of the sealing strip narrow side is ⁇ 0.3-0.5 or ⁇ 1-1.5, particularly preferably ⁇ 2-2, 5 or ⁇ 3-4, usually ⁇ 10-15 or ⁇ 20-25.
  • a "foam body in a relaxed state” is always understood to be one which is completely relaxed or set back in the free state - ie outside the joint or without external force.

  • the compression in the joint is carried out here usually to 20% to 65%, preferably 25% to 50%, in particular about 30% of the body volume compared to the completely free relaxed body.
  • the compression in this case generally corresponds to the compression in the height of the foam body, ie in the direction broadside broadside, so that so the body narrow sides are compressed. Due to the forcibly incomplete provision of the narrow side by the blocking element, the foam body thus in the completely free relaxed state or compression in the joint has a cross-section which tapers to the provided with the blocking element narrow side, for example, converges wedge-shaped. Even in the assembled state of the sealing tape on a roll or in the folded state is usually a compressed body before, with higher compression than subsequently in a joint. As a "body” is always understood in the context of the invention, the foam body.

  • the compression of the narrow side provided with the blocking element with respect to the relaxed body is not particularly limited with respect to high compression values, merely in that the material should not be damaged by the compression of the body material. The extent of the compression then depends essentially on the shape of the strip in the intended arrangement in the joint.
  • the body may be compressed on the blocked narrow side to a residual height of ⁇ 2% to 3% or ⁇ 5% to 10% or ⁇ 15% to 20% of the maximum relaxed volume (each related to the restraint restraint blocking element) completely free relaxed foam body).

  • the transition area between the blocking element and the unblocked body region can be in the range of 5-50% or 10 - 30% of the sealing tape width or body width (respectively for the completely relaxed body).
  • the restoring forces of the foam body after its compression are smaller, preferably much smaller, than the cohesive forces or tensile stress to be applied for elongation of the blocking element in the relaxation direction (broadside-broadside direction), for example ⁇ 20% to 50% or ⁇ 5% to 10% thereof, for example in the range from 0 , 1% to 50% or 2% to 50% or 10-30% of the same, which causes a sufficient remindstellblocktechnik but not too high stiffness of the band.
