Abstract

Plaster plate for false ceilings, of the type of which incorporate a flattened and rectangular body, of constant thickness, endowed in two of its parallel edges, preferably its longitudinal edges, of respective staggered and opposed recesses for coplanar coupling between plates, characterized in that at least on one of said edges, together with the stepped recess, a plurality of notches determining a longitudinal alignment of castellations are established through which said plate rests on the stepped recess of the corresponding edge of the adjacent plate.

Description

Plasterboard for suspended ceilings.

Object of the invention

The present invention relates to a plate of plaster, of the type used for roof decoration, is say to build false ceilings that directly facilitate the aesthetics of the cabin of which they are part, suitable for Certain decoration lines.

The object of the invention is to achieve a stable coupling between plaster plates laterally adjacent, preventing cracks over time between they.

Background of the invention

Within the multiple solutions available for the configuration of suspended ceilings, one of the most commonly used is one in which plasterboard plates are used that are fixed conveniently to the forged or rigid roof to be hidden.

Obviously these plates must adopt a perfectly coplanar disposition and must remain intimately joined together giving a single piece or continuity aspect superficial.

To get the correct coupling between plates, these are normally provided with edges staggered, so that each plate rests on the immediately above through the complementary steps mentioned, thus achieving the intended and due leveling between plates, finally sealing the grooves defined between them by a grout also of plaster.

This solution perfectly valid in principle from the theoretical point of view, it presents in practice and as fundamental problem the fact that with the passage of time and due to thermal expansion, cracks occur in the joining lines between plates, which have a negative impact on the consistency of the false ceiling, and especially in appearance aesthetic of it.

Description of the invention

The plasterboard for construction gives suspended ceilings that the invention proposes fully resolves The problem described above is satisfactory, so that by its special structuring allows an intimate coplanar union between plates, which prevents cracking of the joints with the passage of time, which gives the false ceiling greater consistency and duration.

To do this and more specifically the plate of plaster that is recommended, based on the basic structuring of any conventional plate of this type centers its features in the fact that at least one of its edges incorporates a plurality of notches determining a recess Longitudinal discontinuous, determining both wide and short battlements, which are complementary to the plate recesses immediately adjacent, thus achieving a multiple tongue and groove coupling between plates, which improves substantially the consistency of the joint and that prevents the cracking over time.

According to a variant embodiment of the invention is feasible that the aforementioned notches affect exclusively to one of the edges of one of the plates to be joined, and not to the complementary edge of the second plate, both being edges equipped with the aforementioned stepped and complementary recesses classics, in which case the "battlements" of one of such plates they rest on the staggering of the other and leave empty spaces of width coinciding with that of these battlements, intended to be filled with plaster, which also enhances the consistency of the joint between plates.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of that description, a set of drawings where with illustrative and non-limiting nature, what has been represented next:

Figure 1.- Shows, according to an overview in perspective, a plasterboard for false ceilings made in accordance with the object of the present invention.

Figure 2.- Shows a perspective of the same plate, on its opposite side to that of the previous figure.

Figure 3.- Shows a perspective such that They appreciate the notches or recesses on the side.

Preferred Embodiment of the Invention

In view of the figures outlined you can be observed as the plaster plate that is recommended is constituted, like any conventional plate, by means of a body (1) rectangular contour and variable dimensions, endowed with correspondence with one of its edges of a stepped recess (2), and in correspondence with the opposite edge to the previous one of a second stepped recess (3) opposed to the first, that is oriented in the opposite direction, these recesses being (2) and (3) properly sized so that in the coupling between plates, these are perfectly coplanar both by its upper face as by its lower face.

Well, according to the invention, the body (1) of the plate has, in correspondence with one of its recessed edges (3), a plurality of notches (4), substantially elongated, preferably of equal length, evenly distributed and with distancing coinciding with its own amplitude, notches that, as observed especially in Figure 1, affect the entire height of the longitudinal nerve (5) determined by the stepped recess (3), as observed especially in that cited
Figure 1.

These notches (4) define among themselves battlements (6), which may be complementary to others existing at the corresponding edge of the adjacent plate (1), or that can be defined with the stepped recess (2) of the latter recessed in longitudinal alignment and discontinuous, of appreciable width, destined to be filled with plaster paste, thus enhancing, in any case, the union between plates, to improve its consistency and avoid cracking the false ceiling with the passage of time, as previously
saying.

Claims (3)

1. Plasterboard for false ceilings, of the type that incorporate a flat and rectangular body, of constant thickness, provided on two of its parallel edges, preferably its longitudinal edges, of two stepped and opposite recesses for coplanar coupling between plates, characterized in that at least one of said edges, together with the stepped recess, a plurality of notches determining a longitudinal alignment of battlements are established through which said plate rests on the stepped recess of the corresponding edge of the adjacent plate. 2. Plasterboard for false ceilings, according to claim 1, characterized in that said notches are substantially elongated, with a depth that extends to the level of the stepped recess, identical to each other and separated in an amplitude coinciding with its own length. 3. Plasterboard for false ceilings, according to previous claims, characterized in that the battlements defined by said notches at the edge of a plate are susceptible to tongue and groove engagement in the corresponding edge of the adjacent plate, or to rest on the recess staggered of the latter defining small housings intended to be filled with pasta
plaster.
