Description
Description Metal or non metal section bars with "L". "IP. "Z" shaped cross sections, for the realisation of structural support frames for plasterboard panels and the like, and method for their fabrication
Technical ield
The present invention relates to a method for fabricating multipurpose section bars, manually deformable made of sheet metal, or other suitable material, with "IP. "IP, "Z" shaped cross sections, usable for the structural junction of plane, or curved surfaces, with other plane and/or curved surfaces, whose scales shaping the section bars themsehes can vary their mutual angle, in the realisation of structural suppoπ frames for plasterboard panels or the like. The section bars themselves suitably deformed directly on the constniction site, and appropriately combined, by means of riveting or fastening with self-drilling screws, will allow users to construct a multiplicity of structures, even in particularly complex shapes, with considerable speed and simplicity and hence with evident economic benefits. Some areas of such section bars may be realised with stretched parts, i.e. drawn by stretching on a die, in order to be usable also as wall plaster bearing templates.
Backjrround Art
In mounting plasterboard artefacts, or in panels of other nature, in free shapes, i.e. not constrained by rectilinear profiles or by 90° angles, it is necessary to intervene on a case by case basis with improvised solutions. The technique commonly used by installers is for "L" shaped section bars (for instance), to cut up a scale of the section bar commonly traded on the market until the point where it meets the scale orthogonal thereto, weakening the "L" shaped section bar with respect to the plane whereon the notches have been obtained thereby allowing it to be shaped on that plane and hence obtaining concave or convex curves. In order to obtain the junction between the two planes that meet at angles other than 90c, installers usually hammer on the involved edge until the desired angle is reached.
Such handicraft-like methods lack precision and entail considerable time wastage.
Disclosure of Invention The object of the present invention therefore is to make available to users a series of "L", "IP, "Z" shaped section bars (Figures 1 and 2) produced industrially, which have the characteristic of being able to be deformed manually in a manner compatible with needs for curvature and/or variability of inclination between the planes to be joined according to the requirements of the construction site. The section bars constituting the subject of the present invention (Figures 1 and 2 ) are obtained through the following working phases: a first phase of punching or blanking on a belt of suitable material one or more rows of weakening slots and holes ( 1) placed in longitudinal succession parallel to the longitudinal axis of the belt (Figure 3); a second phase of effecting at least one succession of notches (2), through the removal of sheet metal with triangular or trapezoidal shape, to obtain scales (3 ) with rounded edges, notches effected on at least one of the lateral margins of the belt, from its outer edge to the nearest row of slots and holes ( 1 ); a third phase of bending the belt along said row of weakening slots and holes (1 ) according to open profile "L", UP or "Z" shaped contours, obtained by means of pressure bending or cold forming.
Advantageously the method provides, before said second phase, a stretching phase of some pre-selected areas (4) of the belt (Figure 4).
According to the present invention, with the method described above section bars are manufactured obtained from a belt made of metal or other suitable plane material (Figure 2 and 3), presenting one or more rows of weakening slots and holes (1) placed in longitudinal succession parallel to the longitudinal axis of the belt, at least one succession of notches (2) with the removal of sheet metal of triangular or trapezoidal shape, realising scales (3) with rounded edges, operating on at least one of the lateral margins of the belt, from its outer edge to the next row of slots and holes (1). The section bars are formed by bending the belt along said rows of
weakening slots and holes ( I ) according to open profile "IP, "LP or "Z"' shaped contours (Figures 1 and 2) and can be curved according to axes orthogonal to the longitudinal axis of the belt (Figure 5).
Each of said scales (3) can thus rotate, through manual bending, around the longitudinal axis defined by the adjacent row of weakening slots and holes ( 1 ) (Figure 2).
Advantageously, according to the invention, said scales (3) can present, in proximity with their free end, opposite incisions ( 5) defining a bending line of an outer appendix (6) of the scales themselves (Figures 2 and 3). Moreover, according to an additional characteristic of the invention, the section bars can be manufactured with some stretched areas (4) forming slots (7) (Figure 4), thereby being usable as wall plaster bearing section bars in mixed techniques.
As previously described, to obtain a deformable section bar, current users weaken the continuous scales of the rigid section bars made available to them by industry, effecting cuts on the scales according to construction site needs. This operation entails, in addition to the aforementioned pitch inaccuracies which impact on the precision and aesthetics of the finished artefact, also considerable time wastage, which in turn translates into higher installation costs. A further drawback deriving from said manual operation, is that the blanked scales overlap, thereby creating a double thickness of material which often causes aesthetic and functional problems in the finished artefact. In addition, common section bars existing on the market today give the user no chance to vary the angle between the scales. The section bars constituting the subject of the present invention, instead, thanks to the longitudinal slots present over the entire section bar, allow the user to vary this angle simply by exerting pressure on the edge between the scales themselves. Another advantage offered by the series of section bars thus obtained is the possibility of combining them on the construction site, which allows through the simple mutual fastening by means of rivets or self-drilling screws (as shown by way of example in Figure 5), to obtain a multiplicity of solid structures even in particularly complex
shapes, with considerable speed and evident economic benefit. To allow also those who are not particularly skilled in determining the cuts of the plasterboard panels, nonetheless to complete the construction of works with particularly complex geometries, the section bars are realised also with stretched areas (4) able to house quick-drying plaster wall finishes.
