  • Generic sealing strips can be arranged inside or outside the room at the joint to give the outer seal of the joint, wherein the sealing strip can then optionally be used together with other sealing means such as a polymer foam (local foam).
  • generic sealing strips are known which can extend at least substantially over the entire frame width, ie form both a space outside as well as a space inside sealing of the joint.
  • such sealing strips have to fulfill a wide variety of requirements, for example with regard to the thermal insulation to be achieved, airtightness, watertightness, water vapor diffusion properties and the like.
  • the sealing strip is made up in a form, for example as a roll, which differs from the built-in shape of the sealing strip in the joint or on the frame profile. This is especially true when the sealing strip is impregnated for delayed recovery. If the sealing strip is to be deformed starting from its storage state in order to be fastened to the frame profile or to be introduced into the joint to be sealed off, for example from a roll, the sealing strip is converted into its desired shape only with a certain time delay, for example into a stretched, straightforward state.
  • the attachment of the sealing strip to the frame profile or its introduction into the joint can be delayed or it is easier the risk of incorrect attachment of the sealing strip on the frame profile, for example, that the sealing strip not exactly in its desired position but from this crazy on the Frame profile is attached, or gusset or pockets with improper attachment and conditioning of the underside of the sealing strip remain on the frame profile, especially when mounting by means of a self-adhesive layer. This can also lead to an impairment the air and water tightness of the joint seal lead.

  • the additional strip only from the material of the foam strip itself or from a simple plastic material, whereby the problem underlying the invention can not be solved satisfactorily.
  • the sealing strip according to the invention is easier to handle due to the formation of the additional strip with heavy fractions. This is especially true when the sealing strip is preformed in a form, for example as a roll, which differs from the mounting position of the sealing strip in the joint or the shape of the sealing strip on the frame profile, wherein such a prefabricated sealing strip is included in the invention . It has been found in the course of the invention that the sealing strip according to the invention with heavy material fractions in the additional strip, in particular when this for delayed recovery impregnated or otherwise treated, returns more quickly to its original shape which it had prior to transfer to the storage form, in particular into a stretched, rectilinear shape.
  • the sealing strip according to the invention is thereby easier to handle manually during unrolling and rectilinear alignment.
  • the sealing strip which consists at least substantially of a foam, due to the heavy material shares lighter "by itself” easier flat than without additional strips with heavy material fractions. This is in each case attributed to the increased weight of the additional strip, which as it were depresses the sealing strip as a whole under the action of gravity.

Transverse to these broad sides are narrow sides 1c, 1d of the sealing strip, which bridge the gap 2 and in the installed state of the sealing strip usually have a smaller width than the broadsides. In individual cases, however, the narrow sides may also have a greater width than the broad sides of the sealing strip (which may apply in the completely reset (decompressed) state of the sealing strip, in the installed state the ratio should be a maximum of 1: 1). This can generally apply in the context of the invention.
  • the sealing strip 1 according to the invention further comprises an additional strip 7, which at least partially consists of a material with heavy fractions by which the sound insulation of the joint seal and also regardless of the handling of the sealing strip over conventional sealing strips are substantially improved.
  • the additional strip 7 is formed in the sealing strip of the embodiments overlapping with the foam strip 6, which applies in particular in the installed state. This overlap can be seen in particular with regard to the extension of the sealing strip between the first and second broadside. When the sealing strip is arranged in the compressed state in the joint, the foam strip is thus at least partially compressed by the additional strip.
  • the additional strip 7 is arranged in a channel or groove 6a of the foam strip 6, this groove being open toward the narrow side 1d (which, however, is not absolutely necessary), the additional strip 7 can also be arranged on the upper side of the foam strip 6.
  • the additional strip 7 is attached to the foam strip, here by an adhesive layer 7a, for example, a self-adhesive layer.
  • a suitable fastening means 8b is arranged on the broad side 1b, here in the form of an adhesive layer, in particular a self-adhesive layer.
  • the adhesive layers can generally be covered within the scope of the invention with a peelable protective film (not shown).
  • the sealing strip can be fastened or at least adhered to at least one or both of the bearing surfaces of the frame and wall, so that the sealing strip can be arranged securely in the joint and a proper and long-lasting assembly of the sealing strip is ensured despite the comparatively high weight of the additional strip.
  • the additional strip consists according to the embodiment of a plastic material such as PVC with a mineral or metallic filler, in particular barium sulfate.
  • the filler is distributed in the matrix of the additional strip, more precisely distributed homogeneously arranged.
  • the additional strip has a specific gravity of about 2 g / cm 3 or at a thickness of about 3 mm, a basis weight of 6 kg / sqm, this has the additional strip a suitable proportion of heavy fillers, here barium sulfate in a proportion of about 30 to 40 wt .-% in the material of the additional strip.
  • the additional strip further has according to the embodiment, a thickness of about 3 mm and a width of about 3 cm and has a rectangular cross section.
  • the additional strip extends according to the example over a width of 25 to 50% of the width of the sealing strip, but this depends on the depth of the respective joint and thus the width of the sealing strip to be used.
  • the additional strip has according to the embodiment, a weight per meter running of 150g.
  • the additional strip has a share of about 50% of the total weight of the sealing strip, based on its installed state.
  • the additional strip consists of a non-foamed, so solid material.
  • the additional strip is independent of this from a little rigid material, whereby the sealing strip is rolled up in the longitudinal direction, in particular under compression of the foam material, and when rolling of the sealing strip, this due to the weight of the additional strip slightly on the contact surface, usually the contact surface of the frame profile, adapts (the provided with sealing strip frame can then be inserted on the wall or in the wall opening and fixed in this). Nevertheless, the bending stiffness of the additional strip is many times higher than that of the foam material of the sealing strip.
  • the sealing strip 1 may comprise a further additional strip 9, which contains no heavy material fractions and, for example, is provided for producing an (additional) water vapor diffusion barrier or for other ticks.
  • the further additional strip may also consist of a foam material, also from the material of the foam strip itself.
  • FIG. 1b shows a modification of the embodiment according to FIG. 1a , wherein the fastening means 8b, preferably in the form of an adhesive layer, in particular in the form of a self-adhesive layer, is disposed on the broadside of the sealing strip facing away from the additional strip 7, ie the upper broad side in the figure.
  • the fastening means 8b preferably in the form of an adhesive layer, in particular in the form of a self-adhesive layer, is disposed on the broadside of the sealing strip facing away from the additional strip 7, ie the upper broad side in the figure.
  • this results in handling advantages, for example, if the additional strip is to be arranged on the side facing away from the frame profile.
  • FIG. 2 shows a sealing strip accordingly FIG. 1 , wherein the modification consists in that the adhesive layer 18a, in particular self-adhesive layer, is additionally arranged on the broad side 1a with the additional strip 7.
  • the adhesive layer 18a extends as shown only over the width of the additional strip 7, but may also extend laterally beyond.
  • the adhesive layer or another fastening means for the corresponding contact surface can also be provided only on one broad side (the broad side 1a or 1b) or on both broad sides 1a, 1b.
  • the adhesive layer 18a is only optional here.
  • the fastening means may also extend (optionally only) over the additional strip at the corresponding broad side (as shown here, see adhesive layer 18a). Incidentally, the full content of the statements of FIG. 1 directed.
  • FIG. 3 shows a modification of the sealing strip after FIG. 1 , wherein the modification is in a different profile design of the additional strip 27, for the rest, be full on the comments FIG. 1 directed.
  • the additional strip 27 extends beyond its body 27a beyond the narrow side 1c, for which purpose the additional strip has a flank 27b arranged on the narrow side 1d.
  • the additional strip is thereby formed substantially L-shaped.
  • the additional strip thus extends over a greater part of the height of the sealing strip, especially in the installed state thereof, so that an improved sound insulation is given, and at the same time an increased water vapor diffusion resistance in the region of the additional strip, or with a corresponding arrangement of the sealing strip on the inside of the room the seal.
  • the additional strip may be relatively flat.
  • FIG. 4 shows a further modification of the additional strip 37 after FIG. 1 , moreover, the remarks to FIG. 1 is referenced.
  • the additional strip 37 extends over the entire width of the sealing strip 1, resulting in a further improved sound insulation.
  • the additional strip has a region 37b which projects toward the interior of the foam strip 6 and forms a cross-sectional narrowing of the foam strip 6, thereby further improving the sound insulation. If the projecting region 37b is arranged eccentrically, preferably in the region of a narrow side, this can at the same time serve to produce a water vapor diffusion gradient, so that the sealing strip is more diffusion-tight inside than in the installed state. It is understood that in this case the additional strip 37 does not have to extend over the entire width of the sealing strip, for example according to the FIGS. 1, 2 ,
  • the adhesive layer 8a may extend over the entire width of the additional strip.
  • FIG. 5 shows a further modification of the sealing strip 1 according to the invention, in which the additional strip 47 is secured by means of a profile strip 48 on the foam strip.
  • the profile strip 48 may be suitably connected to the foam strip 6 in a form-fitting and / or cohesive manner, for example comprising an anchoring projection 48a, which protrudes into the foam strip, for example by engaging behind an undercut of the foam strip.
  • the profile strip 48 may be glued to the foam strip 6.
  • the additional strip 7 is attached by suitable means to the profile strip 48, for example, glued to this or fixed in a clamping seat on a mounting profile 48b thereof.
  • In order to allow greater compression of the sealing tape in the installed state of the additional strip 47 and profile strip 48 may have a lower height.
  • FIGS. 6 to 8 show arrangements according to the invention sealing strip in the joint between the frame profile and wall starting from a sealing strip FIG. 1 , it goes without saying corresponding apply to the other sealing strip according to the invention, in particular the embodiments. It is further understood that these representations also apply to the arrangement of the sealing strip 1 on the frame profile, ie independent of the arrangement of the wall. This may apply, for example, when the sealing strip is preassembled on the frame profile in order to be inserted into the associated wall opening.
  • the sealing strip extends at least substantially over the entire frame width FT, thus representing both a seal to the interior of the room RI and the space outside RA.
  • the arrangement of further sealing means for sealing the gap is thereby unnecessary.
  • the sealing strip may also have a smaller width with respect to the respective frame width, thus, for example, only a space inside and / or only a space outside seal results, optionally also with formation of a seal in the middle region of the joint, then below Use of other sealing agents.
  • the sealing strip can in each case be adapted to the general requirements, for example for the outer space-side sealing by a suitable means 62 such as a film, a coating or impregnation reinforced water repellent or impact rainproof be formed.
  • the sealing strip on the inside of the room may have an increased water vapor diffusion resistance with respect to the middle or space outside region of the sealing strip, for example by arranging the additional strip 7 but alternatively or additionally by other means, for example a diffusion-inhibiting impregnation, coating, etc.
  • FIG. 6 shows an arrangement of a sealing strip 1 after Fig. 1 in a joint 2 between the frame profile 3 and wall 4, wherein the sealing strip is arranged compressed between the contact surfaces 3a, 4a of the frame profile and wall.
  • the additional strip 7 serves to improve the sound insulation.
