Description

PLASTERBOARD PANEL WITH GUIDES
TECHNICAL FIELD
The present invention relates to the production of finishing for building works. In particular the invention concerns a plasterboard panel for quickly carrying out during installation the covering elements of any form and dimension, precisely shaped, using simple portable tools of common use. The invention also relates to a method for carrying out said panel.
BACKGROUND ART
The known plasterboard panels consist of a plaster mixture covered on both faces with a cardboard sheet, that gives the panel a suitable solidity and finish.
The panel is cut by scoring a covering cardboard sheet with a cutter and by suitably pressing and folding a part over the other. Since the breaking line follows the made incision, this latter must be traced with precision and for this reason it is necessary both to bring the wished measures onto the panel and to apply a bar by means of clamps, in correspondence of the markings, to maintain the cutter inside the guide.
The main drawbacks of this cutting operation are both the waste of time occurring for every cut, and the inaccuracy of the obtained cut. Thus, the cutter is manually operated and can have some oscillations during the run, since the cutter is driven only by one side with consequent cut inaccuracy. The imperfections can be corrected by stuccoing in case of walls and ceilings, while they are not tolerable in the furniture field.
The millings for bending the panel are much more difficult to carry out during installation: in this case a portable miller must be maintained perfectly closed to the bar, even if this miller is less handy than the cutter.
In the previous Italian Patent Application No.. PS98A 000009, filed on 22/06/98 by the same Applicant, it was described a plasterboard panel arranged with defined incisions and millings carried out during the realisation phase of the plasterboard panels, allowing to cut and to fold the panel quickly and precisely, with the measures and forms which are often used.
However the increasingly wide usage of the plasterboard panels for replacing the traditional pargings and the consequent very different constructive needs, often not allow to use the arranged elements of standard dimensions.
DISCLOSURE OF THE INVENTION
An object of the present invention is to allow a quick and precise realisation of covering elements of any shape and dimension, variously angled, directly during installation using common and economic tools easily available in the market.
A second object is to unify the panel production, by replacing a plurality of differently predisposed boards with a single universal element from which any dimension and shape can be obtained.
The panel in object has, on the back side, thin parallel and regularly distanced grooves, which can be used as a guide for making precise scores, also of considerable length, by means of a simple manual cutter, or millings by means of a portable miller, equipped with a support base of corresponding shape, or cuts by means of a portable electric saw, with a shaped support base.
The grooves can be done during installation, in order to leave integral the covering cardboard, or can be made subsequently onto common plasterboard panels. These grooves can be drawn in one direction, or in two mutual perpendicular directions, in order to form a guiding grid.
BRIEF DESCRIPTION OF THE DRAWINGS
The above described objects are obtained in accordance with the content of the claims.
The characteristics of the invention are evidenced in the following enclosed drawing tables in which: figure 1 shows a transversal section view of a panel with covered grooves, prepared during installation; figure 2 shows a sectioned panel of the same type of figure 1 , after milling at 45 ° per each side; - figure 3 shows a panel section with subsequently scored groves, interrupting the covering rear sheet;
- figures 4 and 5 show two panel portions, of different dimensions, quickly and precisely separated from the grooved plasterboard sheet by means of a common manually operated cutter; figures 6, 7, 8 and 9 show some covering elements of different dimensions and shapes, drawn from the same grooved sheet, manually scored in correspondence with one or more grooves; figure 10 shows a covering element with rounded angle, drawn from the sheet of figure 11; figure 12 shows a grooved metal sheet, which can be coupled with the plasterboard panel groves, to make brackets for the dry connection of the panels, or stiffening elements, for instance in correspondence with self-threading screws;
- figure 13 shows a schematic axonometric view of a panel variant; - figures 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25 and 26 show other examples of covering elements variously shaped, easily obtainable from the panel in object.
BEST MODE OF CARRYING OUT THE INVENTION
In figures 1, 2 and 3, with reference 1 is indicated the chalky layer of the panel, with 2 the anterior covering sheet and with 3 the posterior covering sheet. The reference 4 indicates the parallel grooves, uniformly outdistanced, which score the back portion of the panel, and which act as guide, for example, for the manual cutter so that the panel can be precisely cut, without putting guiding bars by means of related clamps.
The grooves 4 can also act as guide for a milling equipment or a portable miller, provided with a support base with rises fit to be inserted into the same grooves: in this way the panel can be milled during installation with precision, as for instance in figure 2, where the reference 5 indicates a milling fit to allow the panel to be fold at right angle.
The miller is adjusted in order to leave integral the anterior covering sheet, which maintains jointed the two parts to be folded up. Changing the miller, is obviously possible to carry out millings of other forms, to realise covering elements variously shaped, as for instance those represented in the figures 14-26.
The plasterboard elements so obtained, being perfectly finished also in correspondence of the folding, can be used for covering walls, in substitution of the traditional parging, or for covering columns, angled elements, false ceiling and similar elements.
The guiding grooves 4 also allow the realisation of precise cuts 7 as indicated in figure 11, in order to curve the panel, for instance at rounded angle as illustrated in figure 10. In order to make these cuts a portable electric saw can be used, with the support base provided with guides insertable into the grooves 4, for a linear sliding of the tool.
The possibility of making precise workings on the panel with portable tools allows the execution during installation of the desired coverings, of any dimension and shape, avoiding the movement of large sheets, exclusively inserted into the big equipment of fixed plants.
These grooves 4 allow the usage of small tools usable during the installation (at the yard) and therefore the realisation of custom-made elements provided with the desired shapes directly at the yard, otherwise carrying out in a factory with wide dimension fixture.
The plasterings of the sighting parts are not more necessary, especially at the angles, because the sight surface of the plasterboard panel remains integral or at least is provided with distinct and precise cuts so that the panel plastering is unnecessary: this fact cause both a perfect laying of the plasterboard and a remarkable time saving during laying.
The grooves 4 allow a better setting for the adhesive plaster, or an effective dry fixing of the panels, by means of joint application of a grooved metal or plastic sheet 6, shown in figure 12, acting as connecting or reinforcement bracket, for instance in correspondence of self-threading screws for the panel junction with the wall or with adjacent panels.
The panel grooves 4 can be variously outdistanced and have rectangular, triangular, generally polygonal section, or rounded form.
A variant of the panel is schematically illustrated in figure 13 in which the guiding grooves 4 are made along two mutual perpendicular directions, in order to form a guiding grid 8.
In a further embodiment of the panel, the posterior covering sheet 3, which is on the posterior grooved side, covers the inside portions of the groves 4, or stops in correspondence thereof, or covers these latter on the surface, remaining flat. It must be advantageously observed that in correspondence of the cardboard millings or cuts, the used miller or cutter do not cause any "burr" or "scraps" collection near to the posterior cardboard sheet because the cut is made in correspondence of the grooves 4 as can be clearly seen in figure 2.
In other words, in particular in correspondence of the millings comprised between 30° and 110°, in the posterior wall of the cardboard, no scraps are generated because the edges of the cuts made in this way, reach the base of the related grooves 4, often without the cardboard layer, which allow the possible scrap housing so avoiding any interference or any width increasing in correspondence with the angled folding of the plasterboard.
The realisation method of the panels, object of the invention, comprises: - the extrusion of the chalky mixture 1 shaped as panel having an anterior and a posterior wall; the realisation of guiding grooves 4 mutually parallel and outdistanced on the posterior wall; - the covering of the posterior wall with a cardboard sheet 3 disposed between the grooves; the covering of the anterior wall with a cardboard sheet 2.
The method further comprises the covering of the posterior wall of the plasterboard panel with a cardboard sheet complementarily shaped in respect of the same posterior wall.
The use of such plasterboard panel is very easy because the operator, after the regulation of the incidence angle and of the milling cut depth, must only place the relieves projecting from the shaped base of the miller into the corresponding grooves 4 of the panel.
In such a way the operator can made the guided sliding of such miller and made the desired millings and/or grooves on the panel posterior wall.
