  • Patent number: 5862639
    Abstract: An earthquake, fire and wind resistant pre-fabricated building panel comprises a plurality of frame members. The frame members are connected together to form a frame lying in a frame plane, the frame defining a perimeter of the panel, the perimeter bounding an interior portion of the panel. At least some of the frame members are biased inwardly, generally in the frame plane, towards the interior portion of the panel. A first solidified castable substance is cast in the interior portion of the frame, between the frame members. A three-dimensional structure such as a house is formed by connecting the panels together. The connections absorb and distribute seismic forces to the entire three-dimensional structure and the biased frame members act to absorb residual seismic forces reaching the individual panels. The castable substance and biased frame members permit the panel to withstand both positive and negative loading and render the panel fire resistant.

  • Patent number: 5785904
    Abstract: A method of securing an architectural finish element to a surface ultimately formed by a castable material cast about a mesh material involves securing at least one projection to a backing surface of the architectural finish element such that the projection extends away from the backing surface. The castable material is then cast about the mesh material. The projection is then inserted into the castable material before the castable material has set, until the backing surface rests on the surface of the castable material, whereupon the projection co-operates with the mesh material to engage therewith. The castable material is then permitted to set about the projection, thereby firmly securing the projection in the castable material and securing the architectural finish element to the castable material and the mesh material.
