Description

Profile rail for gluing to the substrate for finishing ceramic tiles and the like

Technical field

The invention relates to an angled bar according to the preamble of claim 1 adapted for sticking to clip »clade for limiting the tiles of ceramic plates or the like, comprising a first perforated leg for mounting the ^J thereto angularly connected second leg, on which are formed components directed to adjacent ceramic plates and defining visible joint widths between the outer arm and adjacent ceramic plates.

BACKGROUND OF THE INVENTION

It is known that ceramic slabs laid on the floor as tiles or glued to the walls as cladding are protected at their outer edges by terminating profile strips, for example as described in DE-PS 31 21 823. These profile strips have a substantially L-shaped cross-section. The wider arm of the profile rail is provided with openings and, when laid in a so-called thin-bed mortar bed, is embedded in an adhesive applied either between the substrate or between the masonry and the ceramic plates to be laid or tiled thereon. The second arm, perpendicular to the first securing arm, is the stop arm. At its free edge, this second arm is provided with an extension facing the paving or cladding panels under which a chamber is formed. When placing such a profile rail under adjacent ceramic plates whose edges are to be protected, it is difficult to create and maintain the desired and equally wide joints between the extension of the profile rail arm and the protected ceramic plates. The emerging void of the joint between the widening of the profile leg of the profile rail and the ceramic plates to be protected is difficult to fill with grout, especially if the joint has a small width of the visible area because the joint space

The joints have a relatively considerable depth which corresponds to the entire thickness of the ceramic plates. As a rule, such a protective profile is mounted on the substrate, fixed with glue and then ceramic plates are laid. In this operation, the lower region of the joint or chamber to be formed is already filled with extruded adhesive. However, the joint visible from the outside should be filled with a grout that has a different consistency than the adhesive sealant. In any case, it is necessary to avoid filling the entire joint gap area with adhesive sealant, which would then be visible from the outside. In this case, it is no longer possible to incorporate a sufficient amount of grout into the joints.

GB 2 203 996 A1 describes an end profile bar for forming a corner of the cladding walls, which is then joined by two perpendicular cladding surfaces. This profile rail is provided with two perpendicular fastening arms which are supported on two perpendicular wall surfaces under corresponding external ceramic tiles. The joining of the arms is formed by an approximately quarter-cylindrical section consisting of two perpendicular stop arms and an arched web connecting the outer edges of the two webs. In order to achieve the same width of the joints between the termination arms and the protected outer edges of the ceramic tiles, protruding webs facing the adjacent edges of the ceramic tiles are formed approximately at the center of the termination arms. However, the installation of such profile rails with two fastening arms has proved to be very difficult. Fitting is only possible if the outer surfaces of the substrate, i.e. as a rule masonry wall, are exactly perpendicular to each other in the corner area. Equalization of the angular tolerances seems impossible because, when fixing one fastening arm, the other arm can be retained on the wall only after applying a very large pressing force. However, the springback of the profile rail then lifts the cladding boards in the region above the fastening arm, which only abuts the wall surface after being pressed. Moreover, these profile rails lack the widening at the end of the connecting arms, which leads to the formation of chambers and prevents the jointing material from penetrating to the full depth of the joint and requires a greater protection of the adjacent edges of the ceramic plates.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an angular profile bar of this kind which can be easily installed on masonry under ceramic plates without stressing the external ceramic plates in the corner profile bar after installation and thus performing its protective and support function.

SUMMARY OF THE INVENTION

This object is achieved by the angle profile strip according to the invention, the essence of which is included in the characterizing part of claim 1. The invention provides a profile strip which is fastened under a layer of ceramic tiles to be protected by only one fastening arm. The extension formed on the free edge of the second arm forms, together with the spacer elements for defining the width of the joint joint of the chamber, which separate the jointing mortar from the adhesive sealant. These chambers meet the requirements for anchoring the grout in a known manner, while the expansion of the profile strip ensures perfect protection of the adjacent edges of the cladding boards. A simple securing of the visible joint joint width is also achieved and the adhesive sealant cannot penetrate the joint compound.

The angled profile strips according to claims 3 to 6 are adapted to protect and finish the cladding in the area of the wall corner. The fixing of such a profile strip is carried out only on one side of the wall surface to be lined. Tile section perpendicular to this basic tiled surface ·

wall, can be connected to such a preferably shaped profile strip. The width of the joints is precisely determined on both sides of the profile rail. The formed and inwardly extending chambers between the extension and the spacer elements are easily filled with grout, which again remains separated from the adhesive sealant applied to the substrate.

The profile strip 2 has an inwardly extending or enlarged flange 26 on the upper free edge of the terminating arm 23. preferably slightly increases. The width of the spacer web 24 in a direction perpendicular to its longitudinal axis is by the joint width B greater than the width of the visible upper surface of the extended flange 26 terminated by the leading edge 25.

in the area of contact between two walls lined with ceramic tiles 5, 6. The wall lining is attached to a substrate such as masonry 4. The profile strip 3 is provided with a fastening arm 31, in which a series of through holes 32 are also formed and which is supported under one vertical A connecting arm 33 is connected to the fastening arm 31 at an obtuse angle, to the opposite longitudinal side of which the outer arm 35 is formed, forming a T-shaped cross-section together with the connecting arm 33. The lower arm 35 is shaped accordingly. shaped spacers 36 having a selected width which determine the spacing of the outer edges of the ceramic tiles 5 from the end sections 34 of the arcuate outer arm 35 and hence the width B of the joint. Similar spacers can in principle also be formed on the connecting arm in the same way. The joint space is filled with grout do_ inserted into all joints.

The space 71 may be filled prior to laying ceramic tiles 5 with adhesive sealant or mortar. The spacers 36 also serve to separate the adhesive from the grout
