Definitions

  • the invention relates to a joint sealing element for sealing a joint between a first component and a second component of a building structure.
  • the invention further relates to a sealing arrangement for sealing a joint between two components of a building construction, with a first component, a second component and a generic joint sealing element.
  • Connecting joints usually arise when different components meet. Connecting joints are usually in the connection area of drywall to the ceiling, to the floor and solid walls. Weight bearing and / or thermal influences can lead to lowering or lifting of the ceiling in buildings. In order to avoid damage to the drywall, in this case, the upper connection joint is designed as a movement joint. As expansion joints, therefore, joints for interrupting components are called to prevent stress cracks.
  • connection components which is part of the stud work.
  • the plasterboard panels of the drywall are attached at a defined distance from the connection component.
  • the sealing of the system takes place in the gap between gypsum board and ceiling.
  • a suitable sealant is introduced or the gap filled with mineral wool and provided on the surface with a sealing layer.
  • the material in the joint impedes the movement relatively strong, with the consequence that must be worked to achieve sufficient movement absorption with relatively large joint widths.
  • the sealing of the gap with sealant has some disadvantages.
  • the application of a conventional sealant to a sufficient Sealing of the gap is very strongly influenced by long curing times, depending on the curing temperature and metering of the right amount. It is particularly labor intensive and the seal tends to crack overstress over time. In addition, this approach is prone to error as the user himself must dose the right amount of material to adequately seal the gap.
  • the object of the invention is to provide a jointing element that is easy and safe to use and ensures a good seal without expensive installation.
  • the object of the invention is also to provide a sealing arrangement, which ensures a reliable seal a joint between two components against smoke and fire passage in case of fire.
  • a joint sealing element for sealing a joint between a first component and a second component of a building construction.
  • the first component is a drywall and the second component is a wall, a ceiling or a floor.
  • the joint-sealing element has a support element extending in the direction of the longitudinal extent of the joint with a sealing element made of an intumescent material.
  • the support member has an L-profile which is formed by a first leg and a second leg, which are interconnected at a contact point. In this case, the second leg extends away from the first leg on a second side of the first leg arranged opposite to a first side of the first leg.
  • the sealing element is fastened on the first side to the first leg and extends in the direction of the longitudinal extent of the joint.
  • the joint sealing element is intended to be installed in front of the joint.
  • the legs are in each case on one of the two substantially mutually perpendicular components, directly and / or via the sealing element, on, wherein the sealing element is arranged directly adjacent to the joint.
  • the intumescent material expands into the joint and closes it securely against the passage of smoke and fire.
  • an additional sealing of the joint for example by means of sealant or mineral wool, is not required.
  • the sealing element is in this case dimensioned so that it provides a secure seal of the joint in case of fire.
  • This means the joint sealing element is simple because the user does not have to dose the right amount of sealing material himself.
  • the installation of the joint sealing element is very simple, since the joint sealing element is fastened on the outside in front of the joint.
  • the jointing element can also be used to subsequently seal the joints of existing, in particular incorrectly installed, walls or to improve the existing seal and / or the existing fire protection.
  • the sealing element is provided as a layer which covers the first side to at least 50%, preferably at least 75%, preferably completely. In this way it can be ensured that the sealing element completely covers the joint and / or completely seals in the event of fire. Furthermore, a sealing element in the form of a layer, in particular with a uniform thickness, can be produced cost-effectively.
  • the distance between the sealing element and the contact point may be less than 5 mm, preferably less than 3 mm, in particular less than 1 mm.
  • the sealing element is provided near the second leg and thus in the immediate vicinity of the component on which the second leg is installed for sealing the joint. This ensures that the majority of the gap that extends between the two components is covered by the sealing element. This ensures a secure seal of the joint in case of fire.
  • the sealing element has a bead which extends away from the first side and thus, in the inventive installation of the joint sealing element in front of a joint, in the joint.
  • the bead provides additional sealing material ready to seal the joint in case of fire, thereby improving the sealing properties of the jointing element.
  • the bead can be used in the installation of the jointing element to temporarily hold the jointing element on or in the joint until the support element, in particular on at least one of the two components, is permanently fixed.
  • the distance between the bead and the contact point is less than 5 mm, preferably less than 3 mm, in particular less than 1 mm.
  • the bead is provided near the second leg and thus in the immediate vicinity of the component, on which the second leg is installed to seal the joint.
  • the bead is provided at the location on the joint sealing element, which is opposite to the joint, so that the bead extends into the joint when the support element is installed in front of the joint.
  • the sealing element is formed from a compressible, in particular elastic, material.
  • the sealing element adapts to uneven surfaces and ensures a particularly good sealing of the joint. Furthermore, this also improves the property of the joint sealing element to acoustically seal the joint.
  • the sealing element also has a previously described bead
  • the compressible, in particular elastic, material ensures that the bead can also be inserted into joints that are narrower than the bead is thick. Furthermore, by means of such a material, the joint sealing element can be attached more easily temporarily to or in the joint, until the carrier element is permanently fixed.
  • the sealing element can be integrally connected to the carrier element, whereby a solid, secure and cost-effective connection can be ensured.
  • the joint-sealing element has at least one fastening region extending in the direction of the longitudinal extent of the joint, which is intended to fasten the joint-sealing element to the first component and / or to the second component. In this way, the assembly of the jointing element is facilitated and can be done in less time.
  • the attachment region may have an adhesive layer, whereby the joint sealing element is particularly easy to install.
  • the adhesive layer may in this case be provided in particular for temporary attachment until the carrier element, in particular on at least one of the first and second components, is permanently fixed.
  • the invention further relates to a sealing arrangement for sealing a joint between two components of a building construction, with a first component, a second component and a generic joint sealing element.
