  • the dimension and the material of the joint sealing tape are selected in accordance with the planned use of the joint sealing tape.
  • the dimension of the sealing elements is selected depending on the profile types and the material used. The dimension must be chosen so that the sealing element fills the gap between the gypsum plasterboard and the ceiling and lies sealingly against both the ceiling and the gypsum plasterboard. If a vertical movement of the plasterboard is permitted, the sealing element must follow the movement of the plasterboard so that the contact with the plasterboard does not break off and there is no gap between the sealing element and the plasterboard.
  • the sealing element is preferably made of open-cell foam material and is appropriately pre-compressed during assembly of the plasterboard so that a downward movement of the plasterboard can be followed, which increases the gap between it and the ceiling.

Furthermore, this type is easier to assemble than the aforementioned single or double cladding, since the plasterboard can be easily mounted on the sealing element without measuring the distance. When using a positioning marker, the plasterboard can be installed without measuring the distance. In addition, this type of assembly does not rely on easily compressible materials for the sealing elements and therefore has a relatively large freedom in the choice of material.
  • the joint can be sealed if, in the case of double planking, the two gypsum plasterboards are mounted so that they are offset horizontally in such a way that the outer of the two gypsum plasterboards (also referred to as the outer, second gypsum plasterboard) is higher (i.e. closer to the ceiling ) as the inner plasterboard (also referred to as the inner, first plasterboard).
  • the thickness of the sealing element is chosen in accordance with the thickness of a plasterboard.
  • the first, inner plasterboard becomes like this mounted that the upper edge touches the end faces of the sealing element, with little or no pre-compression of the sealing element is required.
  • the second, outer gypsum board is staggered horizontally, ie it is mounted higher than the first, inner gypsum board, so that it partially covers the sealing element.
  • the sealing element and the gypsum plasterboard should seal against each other in order to seal the gap between the outer, second gypsum plasterboard and the sealing element, in particular against gases. This results in a seal between the sealing element and the second component, for example a ceiling, a wall or a floor, and between the sealing element and the outer, second plasterboard.
  • An empty gap remains between the second component, such as a ceiling, a wall or a floor, and the outer, second plasterboard. In the event of a vertical movement of the second component or of the gypsum plasterboard, this gap is completely available for recording movement.

  • This type of installation allows maximum movement absorption in relation to the joint width. Furthermore, this type is very easy to assemble, since on the one hand the first plasterboard can be easily mounted on contact with the sealing element without measuring the distance. Secondly, in particular when using a positioning marker, the second plasterboard can also be installed without measuring the distance. In addition, this type of installation results in the greatest possible freedom in the choice of the material for the sealing elements, since these are only slightly compressed and therefore only low demands are placed on the compressibility of the sealing element.
  • the joint sealing tape can be applied to all types of connection joints in which one component meets another component. Accordingly, the joint sealing tape can be applied to all profiles, including closed profiles or wooden beams, which must be sealed to form a connection surface.
  • the joint sealing tape can also be used for sealing trapezoidal / corrugated sheets or for sealing from floor to wall, where they in particular enable improved drying.

  • the two joint sealing tape halves each have a sealing element 3a or 3b (not shown), a part 2a or 2b (not shown) of the connecting element 2 and are each partially covered with plastic film 4.
  • On the underside of the sealing element 3a there are openings 5 in the form of slots made in the plastic film 4.
  • Regentetst have shown that the joint sealing tape according to the invention absorbs less water, that there is a very quick equilibrium between water absorption at the cutting edge and water discharge via the drainage openings, that the openings cause less and shorter horizontal spreading of the water, that the joint sealing tape has a significantly better drying behavior and that air contained in the joint sealing tape can very easily escape from the foam when installing the gypsum boards and ultimately, if the foam has absorbed water, it can be expressed very simply, since the water can drain off at any point.
  • the water-draining joint sealing tape according to the invention is particularly suitable for securely sealing a structural joint between two adjacent components in a simple manner, in particular against sound and / or smoke and possibly also against fire, and can also be used universally for different profile widths .
  • the acoustic, smoke-proof and / or fire-proof sealing of connection joints in drywall ensures that, despite installation in an early construction phase, water retention / water accumulation - caused by rainwater - in the joint sealing band is reduced, the water penetration / Water discharge accelerates and a complete drying of the joint sealing tape is ensured.
  • the joint sealing tape according to the invention can be used universally for different profile widths of a U-profile of a drywall frame, in particular for the usual profile widths of 2-1 / 2 inches (64 mm), 3-5 / 8 inches (92 mm), 4 inches (102 mm) ), 6 inches (152 mm), 8 inches (203 mm) and 10 inches (254 mm).
  • the joint sealing tape according to the invention provides a universal product for different profile sizes and applications, which can also be produced inexpensively in a production line.
  • the application is very easy to assemble, since no additional fastening of the joint sealing tape, for example on the profile or on the ceiling, is necessary. Due to the self-centering of the joint sealing tape, fitting the joint sealing tape, for example, to a profile, is also not necessary when mounting the profile on a component. Installation is therefore extremely simple and the work involved in installing the joint sealing tape is significantly reduced. With the invention, therefore, a safe and reliable sealing of joints between two components, in particular between a profile of a drywall framework and an adjacent component, such as a ceiling, wall or floor, is achieved. Sealing on both sides can be achieved in just one work step by providing a prefabricated sealing element.
