Definitions

  • the invention relates to a corner seal according to the preamble of claim 1.
  • corner seal allows for watertight sealing of a corner of a building construction, such as for instance between a recess and a surrounding floor or between a floor and two walls at right angles to each other, and comprises a first membrane section, which is deformed by heat, in a bottom, at least two upright and mutually adjacent walls, and a horizontal flange which extends along the upper edge of the at least two upright walls.
  • a membrane section at least in the corners of a building construction, such as for instance between a recess and a surrounding floor or between a floor and two walls at right angles to each other.
  • This membrane section provides for a watertight transition in the corner, where cracks are usually quick to develop due to warping.
  • a tile layer can subsequently be arranged over these membrane sections. If a join between the tiles were to break after some time, enabling moisture to end up under the tile layer, the membrane section will prevent the moisture from penetrating further into the floor.
  • a membrane section is thus for instance known with a bottom part and, along two edges of the bottom part, mutually adjacent upright wall parts whereby the corner between a floor and two walls can be sealed.
  • a corner seal having a bottom, at least two upright and mutually adjacent walls and a horizontal flange which extends along the upper edge of the at least two upright walls. Such a corner seal is particularly suitable for properly sealing the recess in a floor in which a drain or shower drain is arranged.
  • drains or shower drains which can be arranged both in the middle of a floor and in a floor against a wall.
  • a sealing set of membrane is usually included therewith for properly sealing the drain or shower drain relative to the floor and walls. Because the drain or shower drain can be arranged both freely in the floor and against one or more upright walls, different corner seals are supplied in such a sealing set, only one of which is applied in a specific situation. This can cause confusion for the installer, which may cause the installer to apply the wrong corner seal in a determined situation and possibly even cut up the corner seal in order to make it fit. This may have the result that the corner of the building construction is not optimally sealed.
  • Laid-open publication DE 10 2015 113 119 A1 discloses a corner seal according to the preamble of claim 1.
  • Laid-open publication DE 10 2020 111 264 A1 discloses a sealing set for watertight sealing of a junction region between two vertically offset surfaces and a wall, said sealing set using a first sealing element for sealing a first corner, and a second sealing element for sealing a second corner of the junction region.
  • Laid-open publication WO 2015/104032 A1 discloses a sealing element for watertight sealing of junctions at structural elements of a building, said sealing element comprising a sealing tape having a waterproof surface and a fabric layer to which a sealing compound can adhere and which is fixed to the sealing tape in a manner so that a portion of the fabric layer projects outwardly from an outer edge of the sealing tape, wherein the fabric layer comprises a tear line portion to allow for separating the outwardly projecting portion of the fabric layer by tearing away the outwardly projecting portion of the fabric layer.
  • the invention solves this problem by providing a corner seal having the features of claim 1.
  • This corner seal is characterized by comprising a second membrane section which extends parallel to and along the two adjacent, upright walls and is attached thereto.
  • the corner seal according to the invention can be transformed by a single cut into either a corner seal with the bottom part and mutually adjacent upright wall parts along two edges of the bottom part, or into a corner seal with a bottom, at least two upright and mutually adjacent walls and a horizontal flange which extends along the upper edge of the at least two upright walls.
  • corner seal only one type of corner seal needed thus be included with a drain or shower drain, and the corner seal can be used both for sealing when the drain or shower drain is arranged in a recess in the middle of a floor and in a situation where the drain or shower drain is arranged against two upright walls of a building construction.
  • the second membrane section is arranged on the mutually facing sides of the at least two upright walls.
  • the second membrane section is arranged on the inner side of this tray-like part. It should however be noted that, according to the invention, the bottom need not be wholly surrounded with upright walls.
  • the second membrane section is level in the direction perpendicularly to the bottom of the first membrane section.
  • a strip of membrane can simply be provided for the second membrane section, which strip is not formed and can for instance simply be supplied from a roll during manufacture of a corner seal according to the invention.
  • the second membrane section is arranged on the mutually remote sides of the at least two upright walls.
  • the second membrane section is arranged against the upright walls on the outer side of this tray-like part. It should be noted once again that, according to the invention, the bottom need not be wholly surrounded with upright walls.
  • the second membrane section has in the direction perpendicularly to the bottom of the first membrane section a first, upward directed zone and a second, downward directed zone connecting thereto.
  • the second membrane section is folded and runs away from the first membrane section on the underside of the bottom.
  • the corner seal can hereby be arranged in a recess in a floor without any operations, wherein the downward directed zone can be folded into the recess. A drain or shower drain can then be placed thereover and the corner seal provides for a reliable seal.
  • the first, upward extending zone of the second membrane section is preferably attached to the upright walls of the first membrane section.
  • the first and second membrane section are a watertight membrane which is coated on both sides with a layer of non-woven material.
  • a membrane section is known in the field as sealing membrane and is known inter alia under the brand name Kerdi membrane.
  • contact surfaces, where the second membrane section is attached to the first membrane section to be free from the layer of non-woven material and to be provided with an adhesive layer for mutually adhering the second membrane section to the first membrane section.
  • the first membrane section and second membrane section can be mutually adhered in simple and reliable manner, for instance by providing an adhesive layer on these non-woven-free zones.
  • first membrane section and the second membrane section are formed integrally. This can for instance be done by injection-moulding the first and second membrane section from a very flexible material.
  • FIG 1A shows a perspective view of a first embodiment of a corner seal 1 according to the invention.
  • the corner seal 1 has a first membrane section, which has been deformed by heat, in a bottom 2, at least two upright and mutually adjacent walls 3, 4 and a horizontal flange 5 which extends along the upper edge of the at least two upright walls 3, 4.
  • a second membrane section 6 Arranged against the mutually facing sides of the upright walls 3, 4 is a second membrane section 6 which extends parallel to and along the two adjacent, upright walls 3, 4.
  • Figure 1B shows a first application of the corner seal 1.
  • the corner seal 1 can be placed in a recess in a floor.
  • a drain or shower drain can for instance be placed in the recess.
  • the second membrane section 6 is cut into along the edge 7, after which the second membrane section 6 is folded against the horizontal flange 5 of the first membrane section.
  • Figure 1C shows a second application of the corner seal 1.
  • the horizontal flange 5 of the first membrane section is here cut into so that two edges 8 are created and whereby the horizontal flange 5 can be folded upward and against the second membrane section 6.
  • the corner seal 1 can be arranged in simple manner in the corner formed by a floor and two upright walls.
  • corner seal 1 can be transformed with only a single cut in either horizontal flange 5 or second membrane section 6, wherein the seal of corner seal 1 is not adversely affected.
  • FIG 2A shows a perspective view of a second embodiment of a corner seal 10 according to the invention.
  • the corner seal 10 has a first membrane section (identical to the embodiment according to figures 1A-1C ), which has been deformed by heat, in a bottom 2, at least two upright and mutually adjacent walls 3, 4 and a horizontal flange 5 which extends along the upper edge of the at least two upright walls 3, 4.
  • This second membrane section 11, 12 has a first, upward directed zone 11 with which the second membrane section 11, 12 is attached to the upright walls 3, 4, and a second, downward directed zone 12 connecting to the first zone 11. It can be clearly seen that the second zone 12 is folded.
  • Figure 2B shows a first application of the corner seal 10 for sealing a corner formed by a floor and upright walls.
  • the horizontal flange 5 is cut into along the line 13, whereby the horizontal flange 5 can be folded upward together with the second zone 12 of second membrane section 11, 12. Because the first zone 11 is attached to the upright walls 3, 4, a good seal is maintained.
  • Figure 2C shows a second application of the corner seal 10 according to the invention.
  • corner seal 10 can be arranged in a recess in floor, wherein a drain or shower drain is placed in the recess after corner seal 10 has been arranged.
  • the second zone 12 of second membrane section 11, 12 can be folded against the underside of bottom 2.
  • This second zone 12 can optionally be cut into, although this is usually not necessary because a thickened portion as a result of folding of the membrane section will not cause problems under the drain or shower drain for placing.
  • tiles are however placed on the corner seal, it is desirable to prevent local thickened portions resulting from folding. This can be prevented by cutting into the second zone 12, which has no adverse effects for the seal of corner seal 10.
