Method for obtaining a vertical or horizontal profiled element for the interconnection of plasterboard panels to walls and element obtained with such method
A method for obtaining a vertical or horizontal profiled element for the interconnection of plasterboard panels to walls, in particular to plasterboard walls that can be applied to in-wall frames for retractable sliding doors or for the provision of drywall dividing walls. The method entails a continuous machining of a metallic lamina by punching or drawing or rolling obtained by using two rollers, one acting as a die and the other acting as a punch, so as to obtain on the metallic lamina a plurality of holes, which are uniformly distributed according to a series of mutually parallel rows.
1. A vertical or horizontal profiled element for the interconnection of plasterboard panels to walls, the element comprising:
a planar surface on which there is a plurality of through holes which are uniformly distributed according to a series of mutually parallel rows, in a plan view said through holes have, considering both an upper surface and a lower surface, a substantially X shape, a side or diameter of which is equal to or smaller than three times a measurement of a thickness of said planar surface which constitutes said profiled element, a center distance between two of said through holes that are adjacent being equal to or greater than the thickness of said profile, said thickness being between 0.4 and 1.5 millimeters.
2. The profiled element according to claim 1 , wherein it is constituted by one or more horizontal or vertical profiled elements, by one or more front posts, by one or more abutment posts, by one or more rear posts, by one or more horizontal crossmembers, by one or more upper crossmembers for said rear posts, said front posts and said abutment posts and also by a support for a track/guide for sliding trolleys with which sliding doors or leaves are associated, all made of metal plate, which is used to achieve the support/resting and/or the fixing of plasterboard panels that are adapted to define said walls of an in-wall frame for retractable doors or panels or for installation in frames for the provision of plasterboard walls, characterized in that said plurality of through holes are distributed uniformly according to a series of mutually parallel rows, so as to obtain, between two adjacent rows, an upper surface which delimits each distinct row of said laterally adjacent through holes and is substantially shaped like an upturned U which determines a surface that is inclined in the direction of the adjacent through holes that are arranged at its sides.
3. The profiled element according to claim 2 , wherein each one of said through holes has, in plan view, a substantially conical shape which provides a guide for a needle-like tip of a fastening screw to move toward an axis of the corresponding through hole if said tip is arranged either on said upper surface or at said side walls or surfaces of each one of said through holes and of said upper surface.
4. The profiled element according to claim 2 , wherein a perforated conical tab protrudes, at each one of said through holes, at a lower surface which is opposite said upper surface and produces a localized increase in the thickness of said planar surface.
5. The profiled element according to claim 2 , wherein the side or diameter of each one of said through holes that are provided on said planar surface of said profiled element, and therefore of each one of said horizontal profiled element, said vertical profiled element, said front post, said abutment post, said rear post, said horizontal crossmember, and said upper crossmember, is equal to or smaller than three times the measure of the thickness of said planar surface that constitutes said profiled element [D 1 ≤3S].
6. The profiled element according to claim 1 , wherein the center distance between two of said through holes that are mutually closer is equal to or greater than the thickness of said profiled element.
7. The profiled element according to claim 1 , wherein its thickness is comprised between 0.4 and 1.5 millimeters [0.4≤S≤1.5].
8. The profiled element according to claim 3 , wherein the shape and an arrangement of said through holes and said side walls or surfaces guides a penetration of said tip of said screw, regardless of its arrangement on a side of said planar surface that has said through holes, into an adjacent single through hole, and said head of said screw compresses a skin or layer of paper onto an underlying plaster of said plasterboard panel without breaking a thin paper layer.
9. The profiled element according to claim 1 , comprising, at longitudinal sides of said planar surface, one or more ridges or two side edges or folds and two wings which give said profiled element a substantially omega-like shape.
