Definitions
- the present invention relates to reinforced plasterboard.
- plasterboard will, for simplicity, be used throughout the specification to refer to a building material which is formed from any cementitious slurry resulting in a panel of indefinite length which will be then cut to the required sizes.
- panel is intended in this specification to cover any type of wall, ceiling or floor component of any required size. Numerous proposals have been put forward in the past, many of them patented, relating to the construction of such plasterboard panels.
- plasterboard panels have utilised a gypsum or Portland cement slurry.
- Some of the existing proposals for plasterboard have included the introduction of a reinforcement into the cementitious slurry. This reinforcement has been proposed as comprising glass fibre sheets or fibres, for example.
- a reinforced plasterboard includes at least a first layer of paper, a core of a cementitious material, at least one layer of a mesh reinforcement and adjacent thereto a further layer of paper.
- the mesh reinforcement is in contact with the further layer of paper.
- the mesh reinforcement includes an open weave glass fibre mesh.
- the cementitious material includes gypsum plaster.
- a method of producing a reinforced plasterboard includes providing a continuous feed of a cementitious slurry to spread over a first layer of paper, a continuous feed of a further paper layer, a continuous feed of a reinforcing mesh so as to lie adjacent said further paper layer, means for bringing said layers of paper, said cementitious slurry and said reinforcing mesh together, to result in said cementitious slurry setting between said layers of paper with said reinforcing mesh adjacent said further layer of paper.
- the reinforcing mesh is in contact with said further layer of paper.
- FIGURE 1 shows very diagrammatically a production line for the continuous production of a reinforced plasterboard, according to one possible embodiment of the invention.
- FIGURE 2 shows very diagrammatically a cross sectional view through a reinforced plasterboard according to one possible embodiment of the invention.
- a continuous production line for the manufacturing of a reinforced plasterboard is referenced generally by arrow 1 .
- the manufacturing process is seen to involve in this particular embodiment the feeding of a back paper 2 along rollers 3, 4, 5 and 6, and the feeding of a reinforcing mesh 7 from roller 8, so as to lie adjacent the back paper 2, and in this embodiment contacting it.
- paper is used throughout this specification to refer to any suitable outer facing material which is strong and may be a cardboard such as that made from recycled fibres which may include Kraft paper, or the like.
- the reinforcing mesh may be of any suitable type providing a required density and strength, but a glass fibre or plastics open weave mesh may be particularly suitable such as the commercially available CRENETE (trade mark) mesh.
- a cementitious slurry 1 5 is shown being fed from a feeder 9 which distributes the slurry 1 5 across the width of a face paper 1 1 , fed via rollers 1 2, 1 3 and 14.
- the slurry 1 5 may be of any suitable type, but in one preferred embodiment of the invention, may be a gypsum or Portland plaster.
- Suitable spreading means may be provided so as to ensure that the slurry 1 5 is distributed evenly across the width of the paper 1 1 .
- guide means may be provided each side of the production line so as to turn up the sides of the paper 1 1 so as to form a trough in which the slurry 1 5 can be accommodated. It is envisaged that in one embodiment, the turned up sides of the paper 1 1 may then be folded over and adhered to the back paper 2.
- the process will suitably include heating means to facilitate the setting of the slurry 1 5 and also cutting means, so that the resultant plasterboard can be cut into appropriate sizes.
- a reinforced plasterboard according to one possible embodiment of the invention is shown very diagrammatically with a face paper 1 1 , a plaster core 1 5 such as of gypsum plaster, a reinforcing mesh 7 and immediately adjacent thereto, a back paper layer 2. While in setting, some of the plaster 1 5 will extrude through the openings in the mesh 7 and bond with the paper 2, the mesh 7 may be positioned so as to be in substantial contact across the entire face of the back paper 2. In this way, the reinforcing mesh 7 is providing a substantial and uniform reinforcement of the plasterboard across the entire face defined by the layer of paper 2 and will thus be able to contribute substantially to the impact resistance of the plasterboard.
- the mesh 7 is adjacent the paper 2 but may not be in contact with it.
