Definitions

  • the invention relates to an elastic joint cord and a joint construction made with it and a method for processing a joint. It is known from the sanitary sector to arrange an elastic round cord made of foam plastic in the joint to seal the joint between two components, for example between a wall tile and the top edge of a shower or bathtub.
  • the round cord serves primarily as a spacer between the components.
  • the actual sealing of the joint usually takes place in a later step by applying a permanently elastic sealing material such as silicone in front of the round cord.
  • a permanently elastic sealing material such as silicone in front of the round cord.
  • the problem here is that the silicone joint ages and thus becomes leaky over time. It then has to be renewed, which is very laborious and time-consuming.
  • An elastic joint cord according to a first aspect of the invention is used for arrangement in a joint between two components, in particular in a joint with a wall panel or floor panel (tile).
  • the joint cord is tear-resistant.
  • the "tear-resistant" property of the joint cord according to the invention is determined relative to the (non-existent) tear strength of known joint cords or round cords which are used in the sanitary sector and typically consist of foam plastic.
  • the tear strength of the joint cord according to the invention is at least so great that it has a tensile force acting in the longitudinal direction of more than about 300 N, more than about 600 N, more than about 1000 N, more than about 5000 N, or even more than withstands approx. 10000 N in the long term without tearing.
  • the tear strength of the joint cord depends on the length of the piece subjected to the tensile force, the above information relates to a piece of approx. 10 cm long joint cord (i.e. if both ends of a 10 cm long piece of joint cord are pulled with opposing forces of the stated sizes the joint cord does not tear; however, an elastic or plastic change in length is permissible).
  • the tear strength also depends on the thickness (diameter) of the joint cord if the structure is otherwise the same, with the above information referring to the typical case of a joint cord with a round cross-section of approx. 15 mm 2 in area.
  • the elasticity of the joint cord should be large enough so that the cord can be processed easily, follows the course of the joint and, in particular, can be inserted into a narrower joint by being clamped by compression.
  • the joint cord typically has a large longitudinal dimension compared to much smaller transverse dimensions. In particular, it can extend almost endlessly in the longitudinal direction, with the cross section perpendicular thereto typically being constant everywhere. In particular, this cross section can be circular, but also oval, polygonal or shaped in some other way.
  • the joint cord can preferably be wound up compactly on a roll or prepared as a lengthwise cut.
  • the joint cord can optionally contain a foam material, for example a foam plastic known from conventional round cords. In this way, the desired elasticity (in particular in the form of compressibility) can be ensured.
  • a foam material for example a foam plastic known from conventional round cords.
  • the joint cord contains what gives it tear strength and which is therefore referred to in the following as "strength component".
  • the joint cord without the Typically, the strength component would not be tear-resistant (or no more tear-resistant than known round cords), while conversely the strength component alone is usually already tear-resistant. Despite its tear resistance, the strength component should have sufficient elasticity so that the joint rope as a whole has the elasticity required for its processing. However, the strength component does not necessarily have to have a high level of compressibility, as this property is usually taken over by other components of the joint cord.
  • the strength component is located entirely on the outside of the joint cord.
  • the strength component can extend in the longitudinal direction along the joint cord and cover an angular range of between about 30° and about 270°, preferably between about 150° and 220°, viewed from the central axis of the joint cord.
  • the strength component can also cover an angular range of approximately 180°, ie half of the outside.
  • the material structure of the strength component can be realized in various ways.
  • the strength component can be a wire or contain multiple wires or have a flexible steel sheath.
  • the strength component can be a fabric made of fibers, for example metal fibers or plastic fibers, the term "Tissue” is intended to broadly cover all regular or irregular arrangements of the fibers (ie also knitted fabrics, nonwovens, felts and the like).
  • the outer surface of the joint cord is at least partially designed for the adhesion of a (permanently elastic) sealing material, in particular for the adhesion of silicone.
  • a (permanently elastic) sealing material in particular for the adhesion of silicone.
  • This can be done, for example, by appropriate chemical preparation of the outer surface and/or by suitable, in particular rough, shaping.
  • a rough shape can be provided by the above web of fibers when placed on the outer surface of the joint cord.
  • the tear strength of the joint cord can be combined with good adhesion of the sealing material.
  • a sealing material such as silicone is arranged on (at least) one side of the joint line.
  • Such an arrangement is usually on the side of the joint or joint cord that is accessible/visible from the outside.
  • the sealing material preferably adheres to the joint cord, for example due to a material connection or a form-fitting intervention in a surface structure of the joint cord.
  • the invention relates to a method for processing a joint between a first component and a second component, which is characterized in that a joint cord according to one of the embodiments described above is arranged in the joint.
  • the arrangement is preferably such that the joint cord closes the joint, i.e. bridges the gap between the two components and connects the components.
  • a sealing material such as in particular silicone is applied to one side of the joint line, for example with the aid of a silicone syringe. This preferably creates an adhesive bond between the sealing material and the joint line.
  • the joint cord with the (chemically set) sealing material is removed from the joint by pulling on the joint cord.
  • This processing step can be used to prepare for replacing the joint seal if this becomes necessary, for example, due to aging of the sealing material.
  • the pulling out of the joint cord can optionally be prepared by loosening the connection of the sealing material with the adjoining components, for example with the help of a cutter knife.
  • figure 1 shows a schematic cross section through a joint not according to the invention, which is formed in front of a building wall W.
  • tiles F On the building wall W there are tiles F in the upper area, which are fixed with a tile adhesive and end at a distance of typically five to 10 mm above a built-in object such as a bathtub B.
  • the resulting joint between the built-in object B and the tile F must be sealed against the ingress of water to the building wall W.
  • a sealing tape (not shown) inserted between the built-in object and the tile, as is the case, for example, in EP 1 967 107 A2 is described.
  • the seal is made by a permanently elastic sealing material such as silicone S.
  • the silicone S should be fixed to a maximum of two solid surfaces. So that it has a basis in the joint and does not flow to the wall and glued there, an elastic round cord 10 is first placed in the joint, which bridges the gap between the built-in object B and the tile F. Then before the Round cord in a known manner, the silicone material or the like attached and the joint can be sealed.
  • the tear-resistant round cord is therefore only a flexible filling material, so that the silicone does not migrate in the direction of the wall/floor and forms a three-sided adhesion.
  • the use of specially designed joint cords is proposed according to the invention as the "round cord", which on the one hand are elastic (in particular compressible), but on the other hand also have a high tear resistance in the longitudinal direction. If the joint needs to be renewed after the silicone S has aged, the old material can then be removed particularly easily. After a clean cut through the silicone along the lower edge of the tile and parallel to the surface of the tub, the tear-resistant joint cord can be completely removed, taking the firmly anchored scraps of silicone with it.
  • the tear-resistant joint cord is an independent, flexible component and a fixed connection with the waterproofing layer should be avoided.
  • FIGS. 2 to 7 show various embodiments of a tear-resistant joint cord in this regard.
  • figure 2 contains the joint cord 10 as a strength component, a wire 11, which is located inside and covered by an elastic foam 12.
  • a joint cord can be produced, for example, by extrusion of the foam 12 around the wire 11 .
  • an elastic foam core 22 is completely surrounded on the outside by a jacket 21 made of a tear-resistant material.
  • the material can in particular be a woven fabric made of fibers, for example fibers made of metal (eg steel) or plastic (eg PE). It is advantageous in such an embodiment that the strength component 21 has a certain roughness, which enables the silicone to adhere well.
  • the fabric can be closed or semi-closed, round, square or triangular. In particular, an open structure a steel or plastic mesh offers the silicone an excellent anchoring surface. When the joint cord 20 is torn out of a joint, the silicone is therefore reliably taken along.
  • the joint cord 20 can also consist only of the tear-resistant outer jacket 21, i.e. have no foam core 32.
  • a strength component such as a metal mesh 31 extends only over an angular range of approx. 180° to approx. 200° (seen from the center point of the joint cord) over the circumference of the joint cord 30, the core of which in turn consists of a foam 32.
  • the strength component is arranged in particular towards the room side, so that the silicone can adhere to it.
  • the joint cord 40 from figure 5 has a strength component 41 with a fish-shaped cross-section, ie a pitch circle over approximately 220° to 360° with adjoining ends pointing radially outwards. It can optionally contain a foam core 42 .
  • the joint cord 50 from figure 6 has a strength component 51 with an ⁇ -shaped cross section. It can optionally contain a foam core 52 .
  • the joint cord 60 from figure 7 has a strength component 61 with an angular cross-section.
  • a strength component 61 with an angular cross-section.
  • it may include a foam core 62 and/or angled ends.
  • joint cords are selected according to the joints to be sealed. So the diameter of the joint cords are typically between approx. 1 mm and 50 mm. Contrary to what is shown, other shapes can also be used in addition to round cross sections. Furthermore, the joint rope must be elastic enough that it can be compressed, compressed, bent and shaped as required during processing. It should be able to be easily inserted and deflected as a spacer in an open joint.
