    description
    FIELD OF THE INVENTION
    The invention relates to a construction profile with a surface treatment to increase the adhesion of plaster, especially mineral plaster, especially in wood structures.
    STATE OF THE ART
    The problem of existing construction profiles, in particular profiles for the plaster, such. B. plaster moldings for windows, lies in the consistency of such a plaster layer or in the adhesion of plaster on the surface of plastic profiles. Due to stretching movements, this can lead to the formation of microcracks.
    It is obvious that this problem is more or less solved by a surface roughening of the profile arms, which are to be incorporated into the plaster. Currently meet this purpose mainly the technologically resulting surface unevenness of the profile arms (mainly because of the unevenness of cooling in the caliber or other parts of the extrusion line) or deliberately formed longitudinal grooves in the production process of profiles. A disadvantage of these treatments is their limited effectiveness for a particular purpose, d. H. Increasing the adhesion of plaster on the profile. In the case of technical inequalities, the disadvantage is then also their unevenness and practically also the impossibility of a targeted regulation of their formation in the technological process.
    PRINCIPLE OF THE INVENTION
    The above-mentioned disadvantages are essentially eliminated by the invention of the building profile with a surface treatment to increase the adhesion of plaster. The principle of the invention is that the surface of at least one of the arms of the profile for incorporation into the plaster layer is provided with an embossment formed by a plurality of serially arranged separate recesses with a depth of 0.1-1 mm ,
    The depressions of the embossing can advantageously have the shape of truncated cones with a smaller base area, which is directed downwards. The diameter of the larger base areas is 0.2-2 mm. These recesses are arranged in rows so that the mutual axial distance in one row is 1.3-1.8 of the diameter, the distance from adjacent rows is 1.2-2.0 of the diameter, and the axial offset of the recesses in adjacent rows is 0.5-0.7 of the diameter.
    In another variant depressions of the embossing may have the shape of 3- to 8-sided pyramids or truncated pyramids, wherein the largest dimension of the base area is 0.2-2 mm. These recesses are again arranged in rows, which can be offset from each other.
    The construction profile according to this invention, including its arm, which is provided with an embossment, is preferably made of plastic, in particular polyvinyl chloride.
    One of the advantages of the present invention is the possibility of significant roughening of the arm surface of the profile in all directions with the possibility of regulating the size (roughness) of the roughness through the depth of the indentations of the embossment. This is a general processing that can be used for different profiles with different shapes and with a straight contour, whereby the contour can be continuously realized with high productivity.
    EMBODIMENTS
    The invention will now be explained in more detail with reference to the accompanying drawings. In the drawings: Fig. 1 shows a construction profile with an arm provided with an embossment formed by indentations in the form of truncated cones; and Fig. 2 shows a construction profile with an arm provided with an embossment formed by indentations in the form of quadrilateral truncated pyramids. EXAMPLE 1 A building profile 1 (Figure 1) has the surface of its base-perpendicular arm 2 intended for incorporation into the plaster layer provided with an embossment 3 consisting of a plurality of separate recesses 3a arranged in series is formed with a depth H / T of 0.1 mm.
    The recesses 3a of the embossing 3 have the shape of truncated cones with a smaller base, which is directed downwards. The diameter D of their larger bases is 0.2 mm and these depressions are arranged in rows so that the mutual axial distance in one row is 1.5 of the diameter, the distance from adjacent rows is 1.75 of the diameter and the axial offset the recesses in adjacent rows is 0.6 of the diameter. EXAMPLE 2 Similar to Example 1, the structural profile 1 (Figure 2) has the surface of its base-perpendicular arm 2 intended for incorporation into the plaster layer provided with an embossment 3 which is of a plurality of in Row arranged separate recesses 3a is formed with a depth H / T of 0.5 mm.
    The depressions 3a of the embossing 3 have the shape of truncated pyramids with four-sided base surfaces, wherein the smaller base is directed downward. The largest dimension (edge) P of the bases is 1 mm. These recesses are arranged in rows so that the mutual axial distance in one row is 1.2 in the measure, the distance from adjacent rows 1.5 in the dimension, and the axial offset of the recesses in adjacent rows is 0.5 in dimension.
    INDUSTRIAL USE
    The construction profiles according to the present invention have due to the surface treatment in the form of an embossed increased adhesion of the plaster, in particular of mineral plaster, especially in wooden structures on.
