Definitions

• the present invention relates to a device for sealing an expansion joint between wall or wall sections with an upper plaster layer, in particular facades, with an at least partially made of plastic profile strip and two fixable in the edges of the expansion joint and insertable into the profile rail rails, wherein the profile strip a soft middle part and hard sides attached thereto on both sides, and wherein each side part comprises a longitudinally and substantially perpendicular to a front side of the profile strip extending guide channel having an elongate cross section, which is open to a rear side of the profile strip and formed to receive a leg of the rail is.
• a device of this type is known from DE 100 14 097 Al.
• This device close to the guide channel of a side part in each case two perpendicular thereto extending distance channels, which extend substantially parallel to the front of the profile strip.
• the profiled rails each have a U-shaped cross-section in the region of the side parts, one leg of the U-shaped profile in each case engaging in a distance channel, while the base part of the U-shaped profile is arranged in the guide channel.
• the rail can be adjusted from a first predetermined thickness of the plaster layer to a second predetermined thickness.
• the problem with this known profile strip is that on the one hand it can only be adapted to two different depths of plastering, while usually three standard depths of plastering exist.
• the assembly of the profile strip is relatively complicated.
• this object is achieved in that provided in the guide channel, a holding portion and that on the leg of the rail a cooperating with the holding portion holding member is provided, wherein the holding portion and the holding element form an undercut through which a movement of the retaining element in the direction of the rear side of the profile strip is limited or prevented.
• the fastening of the leg of the profile rail thus takes place directly by holding members provided in the guide channel and on the free leg.
• a U-shaped configuration of the areas of the profile rails to be used in the side parts of the profile strip is avoided so that the transverse distance channels adjoining the elongate guide channel are also not required.
• the side panels are therefore simpler and cheaper to produce and also have a smaller width.
• Differently thick plaster layers can be covered by an appropriate design of the leg of the rail and a corresponding arrangement of the holding elements, so that in in all cases the same profile strip can be used. Since the profile strip comprises a large part of the production costs of the device according to the invention, the costs for a device can be reduced while simultaneously covering different thicknesses of plaster layers.
• the distance between the holding portion and the guide channel to the front of the profile bar towards limiting wall is substantially the same size as the distance between a cooperating with the holding portion of the holding member and a facing the front of the profile strip end of the leg the profile rail. This ensures that the leg is securely held within the guide channel, since the leg is clamped with the holding element within the guide channel in a direction perpendicular to the front of the profile strip.
• the rail has an L-shaped cross section. In this way, a simple insertion of the rail in the guide channel of the side panels is possible because there are no double-angled legs as in a U-shaped profile element.
• the holding element is formed as a bent portion of the free end of the leg of the rail, wherein the portion is preferably bent by approximately 180 ° relative to the legs of the profiled rail.
• the holding element may be formed as an integrally formed on the leg of the profiled rail approach.
• the retaining element preferably comprises a facing the back of the profile strip and in particular parallel to the front of the profile strip extending contact surface, the advantageous one facing the front of the profile strip and in particular bears parallel thereto extending contact surface of the holding portion.
• the holding section comprises a starting slope pointing towards the rear side of the profile strip.
• the holding element may include a run-on slope facing the front of the profile strip.
• the width of the part of the profile rail arranged in the guide channel substantially corresponds to the width of the guide channel. This ensures that the free leg of the rail can be used in the guide channel without further, subsequent to the guide channel additional channels within the side part are required. As a result, a very simple construction of the respective side part is possible.
• a plurality of holding elements are provided on the rail.
• the distance between individual holding elements can be set to the distance between correspond to different standard cleaning depths.
• the middle part comprises a middle section extending between the two side parts and two side sections extending thereon, wherein in each case a free end of a side section is connected to a side part of the profiled strip.
• the connection between the middle part and the side part is preferably provided in each case on a part of the side part located towards the rear side of the profile strip.
• connection between the middle part and the side part may be formed, for example, as a dovetail joint or as another suitable connection.
• the middle part is not connected to its side facing the front of the profile strip part with the side parts.
• the side portions of the central part each have an inwardly directed arcuate profile.
• the central portion of the Mitteilteils has a slightly inwardly directed arcuate profile. Also, a joint formation is largely prevented when used as a corner element.
• the middle part made of soft plastic, in particular soft PVC.
• the side parts can be made of hard plastic, especially hard PVC.
• the use of other materials for the middle part and the side part is also possible as long as they have the required material properties.
• the profile rails are made of plastic, in particular made of PVC, or made of metal.
• the formation of the rail made of plastic is expedient because the holding elements mitange- molded directly, for example, molded or miteinggossen and on the other hand shortening of the leg of the rail is easily possible.

• the dovetail-shaped projection 15 is in each case formed on a free end of two side sections 16 which, together with a central section 17 connecting the two side sections 16, form the middle section 3 of the profiled strip 1. Both side sections 16 have an arcuate cross-section, which is arched inwards, in each case to the longitudinal plane 2.
