Definitions

  • This invention relates to a prefabricated plasterboard element for forming technical and/or decorative architectural details, and a method for producing such elements, in accordance with the introductory part of claims 1 and 13.
  • the formation and installation of technical and/or decorative details is a relatively lengthy and complicated operation.
  • the details are generally formed directly on the site where they are to be installed, starting from a conventional plasterboard sheet of large dimensions (for example 3 m by 1.2 m).
  • the metal section 5 is firstly fitted to a wall 3, then a first piece 1 of the plasterboard detail is fixed to the section, after which the sections 6 and 7 are fixed to the piece 1 and to the other wall 4 respectively.
  • the other plasterboard piece 2 is then fixed to the first piece 1.
  • the surface finish of the exposed corner 7 of the detail hence formed is of poor quality.
  • the corner 7 therefore has generally to be finished manually using a rasp, after which a corner protection tape 8 has to be applied ( Figure 1A).
  • the corner 7 has finally to be carefully plastered.
  • An object of the present invention is to provide a prefabricated plasterboard element for forming architectural details which obviates the aforesaid drawbacks and in particular can be mounted easily and rapidly even by non-expert personnel.
  • a further object is to provide a prefabricated element which once installed does not require plastering or further finishing.
  • a further object is to provide a prefabricated element which is reliable and of low cost.
  • a further object of the present invention is to provide a method for producing prefabricated plasterboard elements for forming architectural details which simplifies and reduces the production time of said elements and enables their production to be automated.
  • the procedure is as follows: from a plasterboard sheet a piece 20 is firstly cut having dimensions equal to those of the element to be formed, after which a notch 121 is mechanically cut in the piece 20 such as to remove a part of triangular cross-section, the notch being made such as to remove a portion of the first cardboard layer 22 and a portion of the plaster layer 23, but leaving the other cardboard layer 24 intact (Figure 2A).
  • This operation can be carried out for example using a conventional milling machine.
  • a usual glue such as a heat-melting glue
  • a glue is then poured into the cavity after which the two parts 29, 30 are rotated towards each other ( Figure 2B) so that the two sides 24, 25 bounding the cavity make contact with each other and with the glue 31 ( Figure 4).
  • This operation can also be easily automated.
  • a means 27 for supporting the two parts and fixing them together is then applied.
  • This fixing means is for example ( Figures 2C and 4) an adhesive tape 27 able to restore and maintain joined together the two constituent parts of the element. It should be noted that the tape 27 adheres to the cardboard layer 21 of the architectural detail to hence ensure optimum bonding between the two parts. It has been found experimentally that simply gluing the two plaster sides 24, 25 together (Figure 2A) does not generally ensure a good connection between the two sides, as the plaster does not offer a good gripping surface.
  • a layer 28 of an adhesive material (Figure 2D and shown by dashed lines in Figure 4) of a type conventional to the expert of the art can be poured into the intrados 26 so that it touches and joins together the cardboard layer 21 of the two parts 29, 30 forming the element. It has been found experimentally that, provided that it grips onto the cardboard layer 21, even the application of a small layer of glue provides excellent joining of the constituent parts of the detail.
  • Figures 3A-3D show a method similar to that heretofore described.
  • a cut 31 is made through one of the cardboard layers 21 and through the plaster layer 22, but leaving intact the other cardboard layer 23 (Figure 3A), the two parts 29, 30 into which the piece 20 has hence been divided are withdrawn from each other ( Figure 3B) and are then retained in this position by a support and retention means which can for example be a usual rigid L section 33 (Figure 3C) or triangular section 32 ( Figure 3D).
  • At least one portion 33A of each of the free edges of the L section 33 is rigidly fixed, preferably by a layer of a conventional glue, to the cardboard layer 27 of the element ( Figure 3C).
  • the section 32 is also advantageously fixed to the detail by a conventional glue. It should be noted that in such a case in order to ensure reliable fixing of the section to the detail a layer of glue 34 is applied along the major sides of the section 32 so that this latter is also fixed to the cardboard layer 21 and not only to the plaster layer 29, which does not offer a good grip. To improve the in any event already good fixing, an adhesive tape can be applied over the section and onto the cardboard layer.
  • Figures 5, 6, 7, 8, 10 show by way of example some of the elements which can be obtained by the aforesaid methods.
  • the element according to the invention consists of a single piece, during installation it is no longer necessary to join various pieces together by joints as was done in the case of details known up to the present time. In this manner the element installation time and cost are further reduced.
  • the aforedescribed method can be used both for forming preformed elements to be stored and sold as pieces of standard shape and dimensions able to satisfy most market requirements, and for forming special pieces once measurements have been taken on site. In this manner and because of the use of automatic machines for forming the elements, these latter have a quality finish and constant dimensional tolerances.
  • the elements according to the invention can be advantageously also used for laterally finishing false ceilings using angular or stepped elements (see for example Figures 6, 7, 8, 9).
  • the aforedescribed embodiments are provided by way of example only, and that numerous modifications all falling within the same inventive concept are possible.
  • the element shapes could be different from the aforegoing, as can the form of the support and fixing means (27, 28, 32, 33).
  • the glued rigid sections 32 could be replaced by a usual expandable adhesive material which on hardening would perform a function analogous to that of the supports 32.
