Definitions

  • the invention relates to a method for sealing during window renovation.
  • the old window frames are first removed from the brickwork, e.g. by means of a suitable window joint saw. Both the interior plaster and the exterior plaster along a straight, sharply defined edge of the old window frame is separated and then removed. This leaves the old disassembled window between interior plaster and exterior plaster a circumferential channel-shaped recess that extends to the raw masonry or even into this. Such recesses are different depths, usually between 10 mm and 100 mm.
  • window frames have a greater width than old window frames, so that when installing the new window, the window frame is no longer used in the recess, but remains outside of the recess.
  • the circumferential recess must be filled in the installed state of the new window with a sealing and insulating material, so that the space between the bottom of the recess and the new window frame is sealed in terms of good building insulation according to the generally accepted rules of technology.
  • the sealing tape again has a layer of flexible foam and a rigid layer.
  • the rigid layer to release the soft foam must not be destroyed, and the soft foam is disposed on the masonry facing side of the rigid layer.
  • the rigid layer is finally pre-assembled by means of various attachment mechanisms in profile channels of the window frame.
  • a similar sealing profile is off DE 20 2010 008 720 U1 known as the closest prior art.
  • This sealing profile comprises a rigid layer, which is firmly connected by an adhesive bond with a frame profile of a window.
  • a flexible foam tape is attached to the rigid layer, which is initially held by a cover in a compressed state.
  • the rigid layer of the sealing profile is first glued to the frame profile of the window and then the window is inserted into the desired masonry opening. Then the cover is removed, so that the flexible foam tape can expand in the direction of masonry and thus seals the gap between the frame profile and masonry.
  • the present invention has for its object to provide a method for sealing in the fenestration, with which the sealing of the new window frame in masonry can be ensured in an efficient and safe manner and can be performed at the same time in a simple way by the craftsman.
  • the retaining elements comprise screws or nails which are anchored in the bottom or sidewalls of the recess after insertion of the sealing band into the recess through the sealing band, the heads of which exert the retaining function on the second layer of the sealing band. In this way, a secure, non-detachable connection between masonry and rigid layer of the sealing tape is made at a fixed distance.
  • the retaining elements comprise flat retaining strips which exert the retaining function on the second layer of the sealing tape. In this way, the sealing tape can be kept flat in a partially compressed state, without the insertion of the new window frame is hindered.
  • the retaining elements also comprise screws or nails, which are anchored in the bottom or side walls of the recess after insertion of the sealing band into the recess through the sealing band, wherein the heads of the screws or nails from the second layer of the sealing tape slightly protrude.
  • the flat retaining strips have in its central portion an opening and are arranged between the heads of the screws or the nails and the sealing strip, wherein the central portion of the flat retaining strips in the inserted state of the retaining strips from below rests against the heads of the screws or nails.
  • the retention function of the sealing band in the recess is ensured at the same time maintaining a predetermined extent of the sealing tape at several points, while after insertion of the new window frame, the flat retaining strips can be easily removed again and thus the sealing tape up against the window frame can expand.
  • the targeted release of the retention function is effected by pulling on at least one laterally projecting tension element, which exerts a force on the second layer.
  • the tension element is preferably firmly connected to the second layer of the sealing band, and it may be formed, for example, as a film-like pull tab.

  • film-like includes, for example, all tear-resistant sheet materials, mesh fabrics, laminated sheets consisting of a plastic film laminated with a backing material (e.g., non-woven), or fabric-reinforced sheets. Combinations of these materials are possible.
  • pull tab 66 When the pull tab 66 is secured to the top of the second layer 20, it is advantageously integrally formed with two mutually projecting pull sections which can be simultaneously pulled in the opposite direction to lift the second layer 20 toward the open access section 14.
  • Fig. 10 illustrates a variation of the embodiment Fig. 9
  • a pull tab 66 is provided as a pulling element, which is fastened on top of the second layer 20.
  • the second layer 20 is here designed in two parts with a breakthrough between the two sections.
  • the attachment of the pull tab 66 takes place on the right and left of the opening.
  • an adhesive tape 68 may still be secured over the opening on the opposite side of the second layer 20.
  • the pull tab 66 is led out here to form a U-shape to one side of the recess 4.
  • the middle part of the second layer 20 is raised in the direction of the access section 14, so that the two sections of the second layer 20 form a pointed roof shape and the jamming of the second layer 20 on the side walls 12 of the recess 4 is released.

  • the pull tab 66 may in the embodiments according to Fig. 9 and 10 a continuous in the longitudinal direction of the recess 4 ausgestaltetes element, but it can also be arranged a plurality of narrow tension elements at certain intervals in the longitudinal direction of the recess 4. In this case, for example, strings of tear-resistant material can be used as tension elements.
  • Fig. 11 shows a further alternative possibility for the provisional retention of the expansion of the sealing band 16 and the targeted triggering of time of the expansion of the first layer 18 of the sealing tape 16.
  • the second layer 20 is clamped to the side walls 12 of the recess 4.
  • the second layer 20 has a narrow edge portion 70, which is connected by means of a perforation 72 or a thin layer separable with the rest of the second layer 20.
  • this edge portion 70 project beyond the sealing strip 16 and thus serve this extension as a tensile section.
  • the edge portion 70 is separated at the perforation 72 or thin spot from the rest of the second layer 20 and thus the jamming of the second layer 20 on the side walls 12 of the recess 4 is released.
  • Fig. 12 shows an embodiment of the embodiment of Fig. 9 similar.
  • the tension element is configured here as an integral, in the longitudinal direction of the recess 4 extending film web 74, which is inserted before insertion of the sealing tape 16 in the recess 4, wherein on both sides of the recess 4 tensile portions of the film web 74 protrude.
  • the jamming of the second layer 20 on the side walls 12 of the recess 4 does not take place directly, but with the interposition of the film web 74th
  • the film web 74 are the same materials in question as for the pull tab 66. Again, instead of the film web 74 several narrow tension elements in certain Distances may be arranged in the longitudinal direction of the recess 4, which may be configured for example as cords.
  • Fig. 13 shows a further alternative possibility for provisionally retaining the expansion of the sealing band 16 and for selectively triggering the expansion of the first layer 18 of the sealing band 16.
  • the second layer 20 is less wide than the recess 4, and jamming of the second layer 20 in the Recess 4, a clamping aid 76 is provided in the region of at least one side surface 22 of the second layer 20, which bridges the gap between the second layer 20 and side wall 12.
  • the clamping aid 76 may be formed as a rolled sealing strip, for example made of foamed plastic, as shown, but it is also possible to use all possible other releasable clamping structures with different shapes and made of different materials.
  • this is unrolled by pulling on a side of the recess 4 protruding tab of the clamping aid 76 and finally pulled out of the recess 4, whereby the jamming of the second layer 20 is dissolved in the recess 4 and the first layer 18 can expand.
  • the sealing strip 16 is inserted into the channel-shaped recess 4 of the masonry 2 and there either by direct or indirect clamping of the second layer 20 on the side walls 12 of the recess 4 or by means of a plurality of retaining elements, of which some examples have been described and which exert a retaining function on the second layer 20 of the sealing band, effecting an at least temporary restriction of the extent of the first layer 18 of the sealing band in the recess 4, before the window frame 24 is inserted in the region of the recess 4 filled with the sealing band 16.
  • the method according to the invention can also be used for the sealing of other channel-shaped recesses 4 in the masonry 2.
  • the sealing tape 16 can still have more than said layers.
  • first layers 18 may be arranged next to one another on a second layer 20.
  • the plurality of first layers 18 may be arranged adjacent to one another or spaced from one another.
  • the plurality of first layers may be made of the same or different material. The latter can for example provide advantages in terms of the different desired air permeability or vapor diffusion differences in the interior and exterior of the masonry ("inside denser than outside").
  • the second layer 20 may have a longitudinal profiling on the edge, somewhat wavy, zigzag or other geometric shapes. On the one hand, this can make the jamming of the second layer 20 on the side walls 12 of the recess 4 more precisely adjustable and, on the other hand, reduce the resistance of the second layer 18 when inserting the sealing strip 16 into the recess 4.
  • the second layer 20 can be provided with longitudinal, diagonal or cross-sections for increasing the elasticity in regions, for width adjustment and for regulating the transverse tension.
