  • Patent number: 8627612
    Abstract: A net layer (32) defines the shell (40) of a building, carried by any necessary supports. A hardening layer (34) is applied to fix the shape of the net layer (32) and to establish wall, roof, and floor. Optionally the shell is of sufficient strength to receive application of further layers in order to define an exoskeleton. Structures of roof sections include parallel-sided segments and converging-sided segments, with troughed or domed section shapes. Structures of walls include opposed shell sides (35), (78) and central filler layers (70), together defining an exoskeleton. Posts (72) can add additional structural capacities for supporting walls, roof and floor and can be formed integrally of net (32) and hardener (34).

  • Publication number: 20070234669
    Abstract: A roofing system provides a stronger bond than conventional roof systems to withstand greater uplift pressures in hurricane force winds, while also providing a sound fire rating. The system includes a non-corrosive metal blocking structure, including a perimeter edge closure that has an anchoring flange for attachment to the roof deck, a parallel upper flange and an intermediate flange extending perpendicularly between the upper and lower flanges. The system further includes lightweight insulating concrete applied to the roof deck and filled between the upper and lower flanges of the edge closure, an inter-ply sheet applied by torch or self-adhesive directly to the insulating lightweight concrete, and a torch applied cap membrane over the inter-ply sheet. Direct attachment of the inter-ply sheet to the lightweight insulating concrete without the use of hardware fasteners preserves the integrity of the underlying lightweight insulating concrete for future re-roofing.

  • Patent number: 6630041
    Abstract: A process for laying small decorative tiles on a surface includes the use of a lightweight plastic matrix having ridges of a desired pattern which are used to locate and space the tiles of different shapes in the desired locations. Tiles of the desired color and shape are placed face down on the matrix. A perforated paper matrix having an adhesive layer is then placed over the exposed back sides of the tiles to maintain their relative positions. The surface to be tiled is then coated with thinset adhesive and the tile strip with the matrix is removed and placed against the surface. Several such tile strips may be placed side-by-side or in a desired arrangement on the surface after which grout is applied between the tiles in a well known manner. The process for producing the paper matrix is also described.

  • Patent number: 6434901
    Abstract: The invention relates to a support and/or drainage plate made of a foil-like plastic material, for use with a plate-lined floor structure or a wall so as to create a space between the ground and the surface lining to be applied onto the foil-like plate. The structure of the plate is such that cavities are created by means of, on the one side, projections extending substantially in one direction and, on the other side, raised areas at the same level between which chambers are embodied for receiving a hardening contact medium, such as mortar or adhesive, which forms a contact layer with the surface lining to be applied. According to the invention the structure consists of projections (N1, N2) or (S1, S2) which extend in at least two directions and intersect. The resulting chambers (M1) are delimited in their circumference by the projections (S1, S2), which are open towards the other side of the plate.
