PREFABRICATED ELEMENTS IN PLASTERBOARD FOR THE REALIZATION OF TECHNICAL, ARCHITECTURAL AND DECORATIVE DETAILS.

1 - INTRODUCTION

The realization of particular architectural forms using plasterboard sheets is increasingly in demand both in the construction of commercial and residential businesses; Such

This requirement can be both technical, for example caissons to hide the passage of technological systems, and architectural

tectonics to give a particular aspect to the environments created. The main feature of the plasterboard construction is the speed of installation and lightness

of the artifact.

For this reason, any precautions that may in some

increasing the speed of execution improves the salient feature of this type of construction technique, and is therefore particularly appreciated.

2 - STATE OF THE ART

At present the realization of the aforementioned details

it takes place entirely on site, starting from the uncut plasterboard sheets (approximately 3m x l, 2m). The operator must take all necessary measurements and cut the plates in the

the strisele necessary for the realization of the detail. The cut takes place without precise dimensional references, furthermore it is made by engraving with a blade, manually, one of the cartons constituting the outer layer of the sheet.

etra, in doing so the underlying plaster is also partially engraved. Taking advantage of the lower resistance due to the sizes

cardboard and the intanilo effect of the engraving on the toilet. the sheet is then simply folded by hand until it breaks at the notch. Last work-

This is to cut also the lower layer of cardboard in order to definitively separate the strip of the plate.

It can be understood that the surface finish of the edge thus obtained will be of poor quality. It is therefore in some cases always finished manually with a rasp, it often comes

left as it is, postponing the recovery of imperfections to the grouting phase.

The joint grouting phase, which is always necessary during the construction of plasterboard products, is simple in the case of flat joints and intrados of an-

goli.

In the case of instead of the extrados of corners, the grouting of

This is a difficult task to perform when good quality aesthetic results are rumored.

Another important factor is that in the part not in sight

of the corners, an element in metal section or other with structural functions must necessarily be positioned.

This entails considerable difficulties in installing and using the

materials in greater quantities than would be needed having preformed corner pieces made of plasterboard only.

3 - PROPOSED INNOVATION

proposes a method for the realization of

preformed details In plasterboard, creating edges of different shapes and sizes, without interrupting the continuity of the plasterboard, in particular on the extrados of the edges.

Furthermore, without the use of materials with structural functions in the part not in view of the edges themselves:

Examples of different types of profiles that can be made with this technique and an example of making a simple toolto box are shown in tables W011 / 2 and W012 / 2 al-

related.

The system can be used both to create particular

preformed pieces to be stored and sold as standard pieces able to satisfy most of the needs that arise on the market, both for making special pieces

take them to the workshop once the measurements have been taken on site.

The realization of these pre-formed plasterboard elements will take place with automatic machinery to obtain a finish of the pieces of constant quality and dimensional tolerances.

The elimination of the difficult phases of construction of the joints on site by creating all the parts making up the joint, juxtaposition of the same and plastering

final curing, involves a great saving in installation times, eliminates the uncertainty in the way of making the joint different from one installer to another and also

allows the realization even to non-expert personnel.

A peculiarity of the system is the obtaining of edges without

terrumpere the continuity of the cardboard layer, thus totally avoiding the grouting and the need to stiffen the joint in the part not in sight.

The phases of realization of a preformed element are illustrated in the attached tables, it should be noted that the action of the glue is also exerted on the plaster, also restoring the

mechanical continuity of this panel component.

Upon failure tests carried out, it was noted that the pre-

formed, subjected to bending do not necessarily tend to break in the joint, demonstrating that the strength of the

panel is reset.
