TITLE: METHOD FOR OBTAINING A VERTICAL OR HORIZONTAL PROFILE FOR THE INTERCONNECTION TO PLASTERBOARD WALLS

DESCRIPTION

The present invention relates to a method for obtaining a vertical or horizontal profile for the interconnection to plasterboard walls, in particular to plasterboard walls applicable to counterframes of retractable sliding doors or for making dry partition walls.

Nowadays it is known to produce door and window frames which provide for the use of a counterframe, positioned inside a wall, within which a door or a panel is slidingly associated, which is also referred to as a "retractable door".

This solution makes it possible to reduce the dimensions of the door inside a room thanks to the possibility of making it slide within the counterframe, thus it is possible to use the space adjacent to the door which would instead be occupied by doors of the type hinged laterally to a cassamatta.

In the known art, the counterframe embedded in the wall is usually constituted by a frame comprising a plurality of horizontal and vertical profiles, a pair of front uprights, a stop upright and a rear upright connected by horizontal crosspieces made of sheet metal, preferably of aluminum, all this by defining a containment box for the panel or door.

The components of the counter frame are usually made by means of processes which substantially provide for the bending of a metal sheet.

Above the box protrudes, along an axis longitudinal to the box itself which develops on the opposite side to the containment box, a track that is hidden by a profile commonly called "upper crosspiece or over door or fanlight".

Trolleys are slidingly associated within the track and are constrained to the upper edge of the door or panel to allow them to slide inside and outside the counter frame.

The end of the track not associated with the vertical uprights is usually associated with the stop upright which acts as a terminal for the stop and abutment of the front edge of the door or panel.

These known types of doors and windows therefore use metal profiles that can be assembled together and sold for example in assembly kits.

To this end, the same applicant is the owner of utility model No. 278468 which illustrates a frame for plasterboard walls or sheets consisting of a first element capable of acting as an upper crosspiece for said rear and front uprights and also as a rail / guide. for sliding support trolleys for a door, said frame being furthermore constituted by centering brackets for an upper frame and support for said walls or sheets of plasterboard.

Although this solution is valid, it has a drawback since, in general, in these solutions, also known as counterframes for dry construction, the external finish of the wall is obtained by overlapping the structure itself with plasterboard plates which are then fixed by means of the aid of conventional fixing systems such as screws, both in the type with self-piercing tip and with pin tip.

This method provides for the need to pierce the sheet forming said horizontal crosspieces placed to support the plasterboard sheets, this sheet having a smooth perforation base.

A certain pressure must therefore be exerted which leads to an initial bending of the profile which increases as the thrust that the installer must exert by means of the screwdriver increases, thus making it difficult to drill the metal.

To obviate these drawbacks, some manufacturers produce structures in which profiles with reduced thickness are used in order to be drilled more easily; this however involves a weakening of the profile on which suitable ribs must be made to stiffen it.

The result obtained, although functional, is however a compromise between rigidity / flexion and thickness and in any case involves a constructive complexity for the profile and a higher manufacturing cost for the same.

Other manufacturers produce systems in which horizontal crossbars are used to support and fix the plasterboard sheets, made of wood instead of metal.

These solutions can help in the fixing operation as wood is more easily pierceable than metal, however wooden crosspieces are more flexible than metal solutions as it is not possible to make them with greater thicknesses than the latter, this in order to guarantee that the whole structure can be housed in the section / thickness of the wall and at the same time be able to house the door or sliding panel inside.

Another drawback that can be found in the known art is given by the fact that the consistency of the plasterboard sheets does not have a high density and therefore makes this material friable, while, on the contrary, the underlying horizontal metal crosspieces have a high surface hardness and have a base of smooth perforation on which the plasterboard sheets rest.

It could therefore happen that the tip of the fastening screw subjected to pressure during the tightening phase slips laterally, screwing in a non-perpendicular way to the crosspiece, with the consequence of having to screw it deeper to ensure that the head of the screw is coplanar to the surface of the facade. external to the wall; as a result, there is a risk that the tip of the screw protrudes too much inside the subframe and damages the door or panel during the sliding and housing phase inside the compartment.

Systems are known in which horizontal crosspieces are used in which the support surfaces of the slabs are embossed to create, by means of a calendering, an incision of a desired design: this solution only allows you to try to prevent the tip of the screw from slipping beyond a given measure determined by the design obtained, but does not prevent it from slipping and therefore does not solve the problem mentioned above, contributing to increasing the structural complexity of the profile and the related construction costs.

The main aim of what forms the subject of the present invention is therefore to solve the technical problems highlighted, eliminating the drawbacks of the cited known art and then devising a method for obtaining a profile that allows to achieve the optimal and rapid support / support and / or the fixing of plasterboard sheets designed to define the sides of a counter frame for doors or retractable sliding panels that can be installed in frames for the construction of plasterboard walls.

Within the scope of the aforementioned aim, another important object is to provide a profile which has a considerable constructive and installation simplicity and at the same time allows to obtain the fastening of usual plasterboard sheets in a stable, durable and fast manner.

Another object is to provide a usable profile to which plasterboard walls are fixed which has an optimal functionality and resistance and also allows to have particularly reduced thicknesses.

Another object is to provide a profile which allows easy fixing to it of plasterboard sheets even by not particularly trained personnel and with screwing means of a known or standard type and easy to find.

Not least object is to provide an invention which is structurally simple, which can be produced with the usual plants and machines and has low manufacturing costs.

The aforementioned task and purposes, as well as others which will appear more clearly later, are achieved by a method for obtaining a vertical or horizontal profile (1) for the interconnection to plasterboard walls (10), which is characterized by the made of providing a continuous machining of a metal sheet by rolling obtained by using two rollers, one which acts as a matrix and the other which acts as a punch, to obtain on the flat surface (12) of said metal sheet a plurality of holes (13) or seats (14), uniformly distributed, said continuous machining defining for the side or diameter (D1) and for the distance (D2) between two of said seats (14) or holes (13) closest to each other and for the thickness (S) of said flat surface (12) the following proportions: D2≥S, 0.4≤S≤1.5 and D1 <3S.

Advantageously, a vertical or horizontal profile (1) is obtained for the interconnection to plasterboard walls (10) which is characterized by having a flat surface (12) on which a plurality of seats (14) or holes ( 13), uniformly distributed, whose side or diameter (D1) is equal to or less than three times the measurement of the thickness (S) of said flat surface (12) constituting said profile (1), the distance (D2) between two of said seats (14) or holes (13) closest to each other being equal to or greater than the thickness (S) of said profile (1).

In the following embodiments, single characteristics, reported in relation to specific examples, can actually be interchanged with other different characteristics, existing in other embodiments.

Furthermore, it should be noted that everything that in the course of the procedure for obtaining the patent turns out to be already known, is intended not to be claimed and the subject of an excerpt (disclaimer) from the claims.

With reference to the aforementioned figures, the number 1 globally indicates a profile to which plasterboard walls or sheets 2 can be associated.

Profile 1 can consist of one or more horizontal 3 or vertical 4 profiles, one or more front uprights 5, one or more stop uprights 6, one or more rear uprights 7, one or more horizontal crosspieces 8 , from one or more upper crosspieces 9 for said rear upright 7, front 5 and stop 6 and also as a support for a rail / guide (not shown) for sliding trolleys (not shown) to which sliding doors or leaves are associated (not shown), all made of sheet metal.

In the particular embodiment, the use of a profile 1 in its various forms used to achieve the support / support and / or fixing of plasterboard plates 2 suitable for defining the sides or walls 10 of a counterframe 11 for doors or retractable sliding panels or can be installed in frames for the construction of plasterboard walls.

In the particular embodiment illustrated, the upper crosspiece 9 also connects the abutment upright 6 fixed at the opposite end with respect to the rear upright 7 and the front uprights 5 are placed at approximately the same distance between said rear uprights 7 and front 5.

The rear upright 7 and the front uprights 5 are transversely connected by said horizontal crosspieces 8 and are positioned at a vertical distance between them such as to divide the length of said rear upright 7 and front uprights 5 in approximately equal parts.

The method makes it possible to obtain, starting from a metal sheet, a profile 1 which has, in each of its embodiments, such as the horizontal 3 or vertical 4 profile, the front upright 5, the stop upright 6, the rear upright 7 , the horizontal crosspiece 8, the upper crosspiece 9, a flat surface 12 on which a plurality of holes 13 or seats 14, uniformly distributed, is obtained.

The through holes 13 can be obtained by means of a drilling step of the flat surface 12 obtained by punching or also by drawing, for example by means of a continuous machining obtainable by rolling and therefore the use of two rollers, one which acts as a die (which determines the conformation and drilling of each hole 13) and the other which acts as a punch (which determines the external shape of each hole).

In the first particular embodiment illustrated, the method allows to obtain, for each horizontal crosspiece 8 and for the longitudinal sides of said flat surface 12, one or more ribs or, as illustrated, two lateral edges or folds 15a, 15b and two fins 16a, 16b which give the horizontal crosspiece 8 a substantially Omega shape; this processing strengthens the profile and makes it less flexible.

As said, each hole 13 is obtained by deformation of said flat surface 12 to obtain, in a cross section, a substantially V-shaped conformation to define, starting from the upper flat surface 17, a substantially conical seat 18 which determines an opening for the tip of a tightening screw and, in correspondence with the lower surface 19, a conical appendage 20, perforated and protruding below said lower surface 19, which determines a localized increase in the thickness S of said flat surface 12.

The seats 14 may not be through and may be obtained by means of punches the tip of which marks the flat surface 12 of the desired depth; in this case too, continuous processing is assumed, obtainable through the use of two rollers.

The seats 14 advantageously have a polygonal shape in plan, preferably square, are equidistant to each other and have, starting from the upper surface 17, a conical seat 18 which determines a recess for the tip of a tightening screw.

The side or the diameter D1 of each of said seats 14 and holes 13 present on said flat surface 12 of said profile 1, and therefore of each of said horizontal profile 3, vertical profile 4, front upright 5, abutment upright 6, upright rear 7, horizontal crosspiece 8, upper crosspiece 9, is equal to or less than three times the measurement of the thickness S of said flat surface 12 constituting said profile 1 itself [D1 <3S].

The distance D2 between two of said seats 14 adjacent to each other or of two of said holes 13 closest to each other is equal to or greater than the thickness S of said profile 1 [D2≥S].

The thickness S of said profile 1 is included between 0.4 and 1.5 mm [0.4≤S≤1.5].

The presence and the particular arrangement of the seats 14 or of the holes 13 in correspondence with the flat surface 12 allows an installer, once a plasterboard wall or sheet 2 has been approached to a profile 1, whether it is a horizontal profile 3 or vertical 4, a front upright 5, a stop upright 6, a rear upright 7, a horizontal crosspiece 8, an upper crosspiece 9, to fix it by positioning the screw in any point of the wall or plate 2 in plasterboard, making sure that the tip of the screw itself intercepts one of said seats 14 or holes 13 and therefore allows an optimal interconnection to be achieved.

It has thus been found that the method has achieved the intended aim and objects, allowing to obtain a profile that allows to achieve the optimal and rapid support / support and / or fixing of plasterboard sheets suitable for defining the sides of a counterframe. for retractable sliding doors or panels that can be installed in frames for the construction of plasterboard walls, this profile is at the same time very simple in construction and installation and allows to obtain the fastening of usual plasterboard sheets in a stable, durable and fast way.

The pin point of the screws for the plasterboard sheets, in fact, finds an invitation so that they slide into the holes 13 or into the seats 14, which are close together in such a way as not to move the axis of the screw too much and this represents a great advantage. screwing for the installer.

The profile maintains particularly reduced thicknesses and allows plasterboard walls to be fixed to it even by not particularly trained personnel and with screwing means of a known or standard type and easy to find.

The invention is naturally susceptible of numerous modifications and variations, all of which are within the scope of the same inventive concept.

The materials used, as well as the dimensions that constitute the individual components of the invention, may of course be more pertinent according to specific requirements. The different means for carrying out certain different functions will certainly not have to coexist only in the illustrated embodiment, but may be present per se in many embodiments, even those not illustrated. The characteristics indicated as advantageous, convenient or the like may also be missing or be replaced by equivalents.
