Abstract

Natural plasterboard with reinforced fibers of unequal continuous shells on its four edges for continuous ceilings and partitions. The galces that the plate arranges for its geometry and dimensions form a parapast. The parapasta is formed by fitting the projecting gutters and the hidden girders, thus facilitating the filling of the joint. (Machine-translation by Google Translate, not legally binding)

Description

DESCRIPTION

Natural plasterboard with reinforced fibers of continuous uneven gauges on its four edges.

SECTOR OF THE TECHNIQUE 5

The sector where the productive activity is developed is plaster, lime and plaster.

PREVIOUS TECHNIQUE

The first type of plates are without galces, which can be made of plasterboard or gypsum plates reinforced with cellulose. These types of plates are manufactured without gauges and in some cases they have a sharp edge so they can be joined with paper tape and joint paste. The assembly is performed 10 edge to edge without a joint between them and on galvanized steel profiles.

The second group of plates are made of plaster with fiberglass and tongue and groove galces. This type of plates are characterized by having male-female galces, where one of the galces enters into the other. These plates are also mounted to form continuous ceilings and 15 partitions. The assembly is on metal or wooden profiles. The adhesive must necessarily be placed plate by plate, due to the geometry of the galces

The third type of plates would be plaster with fiberglass for continuous ceilings that are mounted without profiles. This type of plates have two or four equal galces and are joined together by the back by means of a mixture of vegetable fibers plus plaster, or hanging from the floor by metal braces or straps of vegetable fiber plus plaster. These types of plates are used only for ceilings. The two or four equal galces result in the gap between the plates preventing the adhesive from entering between the plates. In the union of this type of plates no adhesive is used, they are joined by the back with vegetable fiber with plaster. 25 If the use of adhesive were chosen, it would be necessary to mount plate to plate while applying the adhesive at the back of the plate (there is no gap between the rails once mounted) and not at the end of the assembly.

However, experience has shown that it is possible to improve the geometric characteristics of the plates, which are the object of the present invention.

DESCRIPTION OF THE INVENTION

Natural plasterboard with reinforced fibers of continuous uneven gauges on its four edges in order to create vertical and horizontal construction systems. The geometry 35 of the galces means that when the plates are fitted, there is a continuous open joint that does not pass through the exposed face, leaving a parapaste on the rear face, not being necessary to finish said joint on the rear face with a piece that performs that function. .

The natural gypsum board has a protrusion in the longitudinal direction and in the transverse direction, and a hidden in the longitudinal direction and in the transverse direction. The natural plasterboard has defined marks for a correct arrangement of the fasteners as well as the beveled edges to facilitate the introduction of the filling material of the joint.

The purpose of the natural gypsum board is to create a homogeneous back surface 45 prepared to be exposed to the plenum or chamber that originates in these construction systems, the closing of said joint not being necessary on the back side with a piece that performs this function.

BRIEF DESCRIPTION OF THE DRAWINGS

For the best compression of what is described herein, some drawings are attached that represent the natural plasterboard with reinforced fibers of continuous uneven gauges on its four edges.

Figure 1 is a perspective view of the plate where you can see the continuous protruding galce (1) and the continuous hidden galce (2) which, for its configuration, make up the parapastas.

Figure 2 is a cut of the lace of the outgoing galce with the hidden galce that forms the parapastas. 10

Figure 3 is a perspective view of the plate where two sections thereof are marked. Section A-A 'corresponds to the transverse direction of the plate and section B-B' to the longitudinal direction of the plate. In each of the sections the geometry and dimensions of the galces are observed. The difference between (a) and (b) results in a non-through open joint of 15 length (c). For the joint to have a length (c) it must be fulfilled that b> a, but the parapaste would not be formed and the joint filling material would access the rear face of the plates.

Figure 4 details the total thickness (e) of the plate, the thickness of the seen galce (f) plus the thickness of the hidden galce (d).

Figure 5 is a schematic view of the assembly of the four plates (P1), (P2), (P3), (P4) where there is an enlargement where the fit of the protruding rods can be seen with the hidden galces. 25

DESCRIPTION MODE OF EMBODIMENT

The natural gypsum board consists of continuous uneven gauges on its four edges that when mounted on galvanized steel profiles, in any of the most common modulations, forms an open joint which is filled without protruding from the back of the wall. plate thanks to the parapastas formed by the geometry and dimensions of the outgoing and hidden galces.

From everything described and by observing the drawings, the advantages presented by the plates in question, with respect to other preceding embodiments, emerge. 35

Firstly, in figure 3, the purpose of the geometry and dimensions of the protruding and hidden gauges are shown, which, when fitted, form the parapaste that prevents the joint filling material from passing to the rear face of the plate.

In addition, it is necessary to highlight the absence of paper when the treatment of joints between plates is carried out, since only the gap that is left when the plates fit is filled.
