DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to a plastering fillet for window casings, door casings or the like at the transition to the plaster, comprising the following features: window casing, door casing or the like; projects relative to the base wall.
A fillet of this type is known from the publication DE 87 15 604 U.
SUMMARY OF THE INVENTION
In the construction of buildings, window casings and door casings (i.e. the window or door frames fixedly connected to the building) are inserted into corresponding wall openings of the shell and secured therein. In a subsequent phase, the shell will be plastered on the outside and on the inside. In this respect, the connection of the plaster to the window or door casing constitutes a critical point in particular on the outside of the building, since the plaster abuts with its face side to the material of the window or door casing (as a rule wood, plastics or metal) and does not establish a perfect binding effect there. Due to the fact that the plaster shrinks somewhat during drying and as window casings and door casings are subject to vibrations, for example by forceful slamming of the windows or doors, there is a risk that a crack or gap is formed between the plaster and the window or door casing. Moisture may then penetrate at this location, which over the course of time causes damage to the window casing or door casing and/or damages the plaster, resulting for example in breaking out plaster pieces.
The known plastering fillet mentioned hereinbefore comprises an elastic adhesive tape of foam material, acting at the same time as a sealing band, and can be secured to the window casing, door casing or the like by means of the adhesive tape. The adhesive tape effects vibration-decoupling between the window casing or door casing and the fillet having the plaster adjoining the same. Due to such decoupling and due to the improved binding effect between fillet and plaster, a more perfect and longer non-failing plaster joint to the window casing, door casing or the like is created.
In case of the known plastering fillet, the extent of relative movement between the window casing, door casing or the like and the plaster, which the plaster joint established by means of the plastering fillet can sustain without taking damage, is dependent upon the elasticity of the adhesive tape of foam material. However, there are fields of application, e.g. very large windows, windows of relatively high houses, windows subjected to strong winds, in which the elasticity of the adhesive tape is not sufficient for obtaining a tolerance of relative movement in the desired extent.
It is the object of the invention to make available a plastering fillet of the type indicated at the outset, with which higher tolerances of relative movement can be realized due to the principle used in case of said fillet.
To meet this object, the fillet according to the invention is characterized in and a front portion of which the at least one web forms part; which permits relative movement in the direction of a variation in distance to the base wall.
Due to the invention, the fillet no longer needs to rely on a compensation in relative movement by means of an elastic adhesive tape (although such an adhesive tape may be provided for attachment and for additional de-20 coupling), but rather, the tolerance of relative movement is present in the fillet itself, i.e. between the base portion and the front portion thereof. It is thus possible without any problem to realize a possibility of relative movement of greater extent than was previously possible.
There are numerous constructional possibilities for the design of the connection rendering possible said relative movement between the base portion and the front portion of the fillet. Particularly preferred is a design as a pluggable connection, with the relative movement being rendered possible by further mating and limited pulling apart, respectively. The connection preferably is a pluggable connection that is elongated in the longitudinal direction of t
