Definitions

  • the invention discloses a method for solving the problem of building stone slabs reinforced by a panel having an internal honeycomb structure, or by a polyurethane internal structure with holes and/or grooves to form small cells, wherein said reinforcing panel shows an improved adhesion to the slab and it is built starting from a naked honeycomb structure (without skins) during the production procedure, thus allowing to directly obtain said reinforced stone slabs in planar or non planar form.
  • the invention finds use and application in the general field of stone coverings and linings mainly in the shipbuildings, housebuildings and furniture sectors.
  • honeycomb the material generally known as honeycomb or sandwich panel, which is formed by a honeycomb structure placed between two sheets (skins), as disclosed for example in US 3,723,233, or a panel of polyurethane foam, or a panel made by a material, to be found in nature or industrially built, endowed with the desired structural properties.
  • Panels internally structured with central honeycomb are a choice solution whenever low weight and high specific structural strength are required; whenever thermal or acoustic insulation would be preferred, plastic foams would find better use.
  • planar panels All these materials are industrially produced, in big quantities and following strict specific procedures, in the form of planar panels (and mass produced are also their basic components, like the internal honeycomb structure, to be later used for producing the same panels). Therefore the said technical problem has got many and different solutions, for planar stone slabs.
  • this inventor disclosed a solution by his international patent WO 2009/060492.
  • This application discloses a method for reinforcing curved stone slabs starting from honeycomb sandwich panels by removing the skins from the central honeycomb structure (destructuration), then applying the single removed elements to the back in such a way as to accommodate each of them in the shape of the curved slab, performing then a strong connection between them by means of glue.
  • honeycomb panel as industrially produced and sold to the general public is lined, on both its faces (in a sandwich like fashion) by means of a fabric or sheet (skin) glued to its internal honeycomb structure.
  • the honeycomb panel is glued to it by means of a special glue to produce a veiy strong bond between the material of said fabric or sheet and the stone itself.
  • This invention proposes a solution to said problem, greatly bettering the honeycomb structural reinforcements presently applied and the adhesion thereof, in the case of planar stone slabs and also in the case of non planar stone slabs, for example curved slabs, by means of actually mending said critical point: therefore achieving the goal of increasing and improving their applicability in the building and furniture industries, especially in their most advanced and most requiring sectors as ship and yacht furniture sector.
  • a sheet of nylon or of other material with no adhesive properties will be put on a table; upon said nylon sheet will be spread a first woven fabric (a fiberglass or silica fabric will be preferred, not excluding other materials useful or proper for specific ends) which is a pure and unused fabric; upon said fabric will be poured and spread a glue (a structural epoxy resin will be a preferred solution as described here below) in amounts and quantities such as for said fabric to be imbued by it and to drench, by surface adhesion, the reinforcing material, placed in contact with said fabric, and its immediate surroundings.
  • the reinforcing material here proposed is the naked honeycomb structure without skins, which is not thus in the form of a sandwich panel.
  • This naked structure is available, and to be acquired in the market, in its compacted form as a rod, with given height and dimensions, in aluminum or other metals.
  • Said rod will be opened by laterally stretching it, as for an accordion, to form a sort of reticular structure, with tridimensional empty cells of height given by construction and width and length given by the lateral pulling effort,
  • Said structure, opened in said way will be made to rest upon the resin impregnated fabric in such a way that the resin itself will wet and adhere to, by surface adhesion in the immediate surrounding of the contact points, the sides of the walls of said opened cells.
  • the whole will be lightly warmed up in oven for a first maturing of the resin at a preferred temperature as defined here below.
  • the face of the stone material to be reinforced (defined herein as the back of the slab) will have the rough surface finishing given to it by cutting, polishing or other methods of surface working processes.
  • a second pure woven fabric a fiberglass or silica fabric will be preferred, not excluding other materials useful or proper for specific ends
  • a glue a structural epoxy resin will be a preferred solution
  • the used structural resin is an epoxydic bicomponent resin and has such characteristics as to allow a suitable adhesion between the stony material and the honeycomb structure with an high tight between said two elements, and to allow the impregnation of the fabric thanks to the specific parameters of viscosity, specific gravity, and structural strength at high temperature (up to 90°C) before and after maturation.
  • Such specific parameters are required to the supplier in order to obtain a minimal desired mechanical strength, evaluated according to ASTM D 638 (direct tensile test) and according to ASTM D 1002 (shear strength test), depending on the final use.
  • a non limitative example is a structural bicomponent epoxydic resin having a minimum resistance of 60 MPa according to ASTM D 638 (direct tensile test) and 7,5 MPa according to ASTM D 1002 (shear strength test).
  • the honeycomb structure prepared as above, will be put in contact, with the open side (i.e. the side not covered by the first fabric) of the honeycomb cells, to the said second resin impregnated fabric which covers the back of the stone slab to be reinforced, in such a way that the resin will drench by surface adhesion, in the above described ways, the contact points of said honeycomb structure and its immediate surroundings, the wall of the cells.
  • a non limitative example of optimal conditions can be as follows: a temperature comprised between 30°C and 70°C depending on the type of stony material, preferably about 60°C; pressure ranging from under vacuum (0 atm) to 1 atm, preferably under vacuum at 0 atm, for a time comprised between 1 and 8 hours depending on the type of stony material, preferably about 6 hours.
  • the product, resulting from said procedure, is new and, because of its properties of strength and durability, confronts itself veiy favorably to similar products actually proposed. From said procedure can result also a new, simplified product, where the fabric between the stone slab and the naked honeycomb structure is omitted (the resin being poured and spread directly upon the stone slab and the naked honeycomb structure which will be made to rest upon the slab itself).
  • the process of the present invention allows to build the honeycomb panel simultaneously to the process for reinforcing the respective stone slab.
  • the Applicant has found that the use of a pure honeycomb structure without skins, in place of a honeycomb sandwich panel, allows to obtain an improved adhesion between the reinforcing honeycomb structure and the planar stone slab since the detachment of the honeycomb reinforcing structure from the skin glued to the slab does not occur as instead in the prior art.
  • a fabric is more impregnable by the resin, which drenches it and pass through said fabric, with respect to the sheets of a preformed panel, and allows to connect directly the objects that are on the faces of said fabric. Furthermore, the pure fabric is also more impregnable than the fabrics of the preformed honeycomb panels since a portion of said fabric surface of said panel is already occupied by the original glue of the panel, thus offering less surface to the resin for the impregnation.
  • the present invention is also advantageously applicable to curved slabs since, in this case as well, it is obtained an improved adhesion of the reinforcement with respect to that obtained by following the teaching of WO 2009/060492.
  • the impregnation of a pure fabric is greater than that of a delaminated fabric or sheet of a preformed honeycomb sandwich panel since said delaminated fabric or sheet normally has "dirty" zones where the original glue is already present and which cannot be impregnated by the resin, thus attaining to a minor adhesion.
  • a pure honeycomb structure is more drenchable with respect to a detached honeycomb internal structure since the latter has cells which are dirty due to the previous gluing: thus a minor surface is available for the impregnation with the structural resin, thus resulting in a minor adhesion of said honeycomb reinforcement to the stone slab,
  • the central honeycomb structure without skins can be replaced by a foamed polyurethane central structure of a panel, generally used for insulation, in which holes and/or grooves have been formed in both surfaces in such a way as to form small cells, also passing through cells, in analogy with the cells of the honeycomb structure.
