Abstract

Provided are building panels comprising at least one magnet receptive element, methods for making such panels, and kits and methods for attaching objects to a panel without nails or screws.

First claim

What is claimed is:

1 . A building panel comprising a magnet receptive element.

2 . The building panel of claim 1 , wherein the panel comprises a gypsum core covered on at least one side with a paper sheet and the magnet receptive element positioned in at least one of the following locations: embedded in the gypsum core, embedded in the paper sheet, adjacent to at least one surface of the gypsum core, adjacent to at least one surface of the paper sheet, or a combination thereof.

3 . The building panel of claim 1 , wherein magnet receptive elements create a pattern selected from: a disjointed pattern, discontinuous pattern, continuous pattern, grid, array, geometrically spaced, randomly spaced, spaced in at least one direction, and any combination thereof.

4 . The building panel of claim 1 , wherein the magnet receptive element comprises a ferromagnetic material selected from the group consisting of iron, nickel, cobalt, alloys with rare earth metals and any combination thereof.

5 . The building panel of claim 1 , wherein at least one magnet receptive element comprises at least one of the following: a tape comprising a ferromagnetic material and a paint prepared with a magnet receptive material

6 . The building panel of claim 1 , wherein the magnet receptive element is capable of producing a magnetic field.

7 . The building panel of claim 1 , wherein a cover sheet is applied over the magnet receptive element.

8 . The building panel of claim 7 , wherein the cover sheet is selected from the group consisting of paper, plastic, coating and any combination thereof.

9 . The building panel of claim 1 , where the panel is selected from the group consisting of a gypsum fiberboard, gypsum wallboard, cement panel, ceiling tile and plastic panel.

10 . The building panel of claim 1 , wherein at least two magnet receptive elements create a grid with intersections between magnet receptive elements, and wherein the grid is disjointed and magnet receptive elements do not connect at the intersections.

11 . The building panel of claim 1 , wherein at least two magnet receptive elements are located so that the angle and distance between the elements can be of any value.

12 . The building panel of claim 1 , wherein at least one magnet receptive element comprises at least one of the following from the group consisting of: a magnet receptive tape, magnet receptive sheet, magnet receptive paint, magnet receptive coating, foil, shim, magnetic tape, magnetic sheet, magnetic paint, magnetic coating, and any combination thereof.

13 . The building panel of claim 12 , wherein the tape is ferrous metal tape, a magnetic field producing material, or any combination thereof.

14 . A method for making a gypsum panel, the method comprising positioning at least one magnet receptive element on the gypsum panel.

15 . The method of claim 14 , wherein the magnet receptive elements are positioned on the gypsum panel by a method selected from the group consisting of:
painting the magnet receptive elements on at least one surface of the gypsum panel; printing the magnet receptive elements on at least one surface of the gypsum panel; attaching the magnet receptive elements with an adhesive to at least one surface of the gypsum panel; attaching magnet receptive elements by using a mechanical attaching design or device to at least one surface of the gypsum panel; depositing the magnet receptive elements on the surface of the gypsum panel which has not been fully set; and any combination thereof.

16 . The method of claim 14 comprising:
placing at least one magnet receptive element on a cover paper sheet;
preparing a gypsum slurry;
depositing the gypsum slurry onto the sheet over the magnet receptive element;
forming the slurry into a panel; and
allowing the panel to set.

17 . The method of claim 16 , wherein the magnet receptive element is selected from the group consisting of a magnet receptive tape, magnet receptive sheet, magnet receptive paint, magnet receptive coating, foil, shim, magnetic tape, magnetic sheet, magnetic paint, magnetic coating, and any combination thereof.

18 . The method of claim 16 , wherein the magnet receptive element is adhered to the cover paper sheet with an adhesive.

19 . A kit for making a building panel, the kit comprising an item selected from the group consisting of: a magnet receptive tape, magnet receptive sheet, magnet receptive paint, magnet receptive coating, foil, shim, magnetic tape, magnetic sheet, magnetic paint, magnetic coating, an adhesive, a resonator, a magnet induction (MI) signal repeater, and any combination thereof.

20 . The kit of claim 19 , wherein the kit further comprises a magnet selected from the group consisting of alnico magnets, magnets made from ferromagnetic materials, rare-earth magnets, ceramic magnets, neodymium magnets and any combination thereof.
