Definitions

  • the invention relates to a movement joint profile and a floor construction with such a movement joint profile.
  • Expansion joint profiles which are colloquially usually referred to as shrinkage joint profiles, are commercially available in multiple forms and generally consist of two-piece metal structures with perforated mounting brackets or plates and a flexible insert disposed between the mounting brackets.
  • Such motion joint profiles are not only expensive to manufacture, but also expensive to use, since they are not only relied on the screed in exact height for lying on top of it, depending on the burden, but must also be partially bolted to the subfloor.
  • the invention has for its object to provide a simple and, in particular better installable in a joint space movement joint profile.
  • this object is achieved by a movement joint profile with the features of claim 1 and / or by a floor construction with the features of claim 11.
  • the metal profile webs that go through the top layer protect and support the edges of the floor coverings, the molds swiveling into the joint space or elastic backfills ensure that the joint space remains free so that movements can be compensated for.
  • the shape of the movement joint profile ensures in particular a solid protection against the adjacent edges of the tiles or slats.
  • the movement joint profile is very resistant to an abrasive influence from above.
  • a very significant advantage of the solution according to the invention consists in the very simple installation and assembly work.
  • the movement joint profile can be adapted in the course of the actual laying work on the particular circumstances and in particular on the structure of the respective joint.
  • the movement joint profile can be adapted particularly advantageously both in the horizontal width and in the vertical height of a joint space for a floor construction.
  • elaborate preparatory work for measuring and adjusting the respective motion joint profiles are no longer necessary because a processor of the motion joint profile can make the adaptation of the motion joint profile to the conditions in a simple manner on site.
  • the processor can locally adjust the movement joint profile according to the invention into a cut groove or a corresponding joint space of the floor construction, pat in and then simply push and compact the mortar or screed again.
  • the L-shaped portions have substantially horizontally projecting from the respective legs foot portions, which are preferably formed flattened.
  • the legs on the side facing away from the apex line, in the region of the L-shaped sections edges, of which the L-shaped sections are arranged in the vertical direction, ie extending to the apex line and of which the foot sections in the vertical Direction are arranged offset.
  • a distance between an edge and the associated foot sections of the L-shaped sections defines a height, wherein the two foot sections each have different heights from each other.
  • the movement joint profile on a one-piece, continuous extending, V-shaped or U-shaped metal part, which is bent at the edges and which has a section with double wall thickness in the region of the L-shaped sections. Due to the typically folded, i. bent edges of the motion joint profile, this is particularly impact-resistant. In particular, the movement joint profile is impact resistant even when knocked into a corresponding joint space.
  • the movement joint profile according to the invention preferably consists of a metal profile, which due to its Geometry and molding can be compressed, ie, which can be compressed for installation in the floor in the horizontal direction and which then presses firmly into a joint space.
  • the foot sections are covered on their side facing away from the apex line with a strip of preferably flexible or elastic material.
  • the strip may be, for example, an adhesive strip.
  • a height compensation element which has an adapted to the profile of the movement joint profile in the region of the apex recess, in which the legs are used with the apex line ahead at least in sections.
  • the height compensation element comprises a foam material or a flexible material.
  • the height compensation element can be connected, for example, in one piece or in one piece, fixed, ie inseparable, or releasably connected to the legs.
  • a resistance element is provided, which is arranged between the legs and which is movable in the horizontal direction of the movement joint profile so as to divide the legs apart.
  • the resistance element is preferably provided in a vertical direction fixed between the legs.
  • the resistance element can be, for example, a flexible hose, a foam element or the like, which, due to its flexible, elastic material properties, preferably expands in horizontal and, if necessary, also in the vertical direction during, for example, relief. Additionally or alternatively, it would also be conceivable if the resistance element also in a horizontal direction, as it were as a wedge is movable between the two legs. This makes it possible to realize a wedge effect by which the two legs are removable from each other in the horizontal direction.
  • At least one leg has teeth bent out of the respective leg.
  • the thus exhibited teeth which engage in the adjacent mortar, support the movement joint profile against from above acting forces, so that the movement joint profile can not be pushed down into the floor structure (or about can be pulled out again).
  • the legs of the movement joint profile according to the invention are preferably made of stainless steel and z. B. in a roll forming process, but they can also be extruded or roll formed from aluminum or brass. Also conceivable would be a sheet metal construction.
  • insulation, seals and / or separating layers are arranged on the plate.
  • the plate is designed as a concrete slab.
  • the fields are formed of screed or mortar.
  • the surface covering is designed as tiles or plates.
  • At least one height compensation element is provided, which is arranged in the joint spaces below the movement joint profile or which is part of the movement joint profile.
  • the height compensation element preferably has a shape adapted to the profile of the Schundfugenprofile in the region of the apex line for at least partially receiving the movement joint profile. This allows in their vertical height Equally dimensioned motion joint profiles are used even at different heights of construction of the floor construction or the joint spaces, for example, by adjusting the height of the height compensation elements by simply cutting to the height of the available joint space. This can preferably be done directly on site, which offers a much higher flexibility.
  • a recess formed by the L-shaped sections of the movement joint profile is flush with the surface filled with a flexible filling material.
  • a recess formed by the L-shaped sections of the movement joint profile is flush with the surface filled with a flexible filling material.
  • laterally bent teeth are embedded in the screed or mortar from the legs of the movement gap profile.
  • the legs of the motion joint profile are provided with laterally pressed out by partial punching teeth, which anchor after installation of the movement joint profile in a floor construction in the laterally applied mortar or cement paste and optionally can be pulled apart in the direction of the mortar or screed.
  • the movement joint profile according to the invention can be stressed in both horizontal directions, ie in the case of an expansion of the fields by the action of heat, but also in the case of a fading of the individual fields, for example as a result of the hydration of the mortar or cement paste.
  • a particular advantage is obtained in a motion joint profile according to the invention, especially from the combination of stainless steel with foam plastic.
  • the legs made of stainless steel are provided in an upper region of a joint space and thus act in the loading zone of the joint space.
  • foam plastic is provided in the lower part of the joint space. Since this foam plastic can be cut very easily leaves the height of the entire movement joint profile can be very easily adapted in its height to the respective height of a joint space.
