  • Patent number: 5473849
    Abstract: A simple, environmentally benign building for on-site erection and fabrication is made of monolithic, architectural, structural walls, beams, girders, joists and panels of relatively high physical strength which exhibit great durability and resistance to fire, wind and seismic damage and which have highly desirable acoustic and thermal transfer characteristics. The wall is constructed by casting a core of flowable fibrous, foam-cement mix between two, thin panels of manufactured, exterior-grade fiberglass reinforced cement board. Particles and proteins from the core mix penetrate, migrate into and fill interstitial spaces in the cement board, forming a strong, continuous and homogenous bond between the fill material and the board itself. This imparts additional strength to the cement board by filling the interstitial voids, creating a solid, homogeneous wall. The wall, girder, etc.

  • Patent number: 5392580
    Abstract: A generally rectangular wire grid of welded construction is utilized to define and maintain the positioning of rebar charged therethrough during the formation of structural column and girder cages. Pre-positioned ties guide the rebar through the grid. The pre-positioned ties are then tightened such that the rebar is held firmly in place at the close tolerance positions defined by the prefabricated grid. A plurality of such grids are assembled into expandable bundles such that they may be expanded in an accordion-like fashion about rebar charged therethrough, resulting in properly spaced grids for defining and maintaining the position of the rebar. Additional rebar members may then be charged therethrough to complete the construction of a column or girder cage. The modular reinforcement cages of the present invention thus eliminate piecemeal engineering requirements by providing modular building concepts in which a unique rebar bundle pattern facilitates improved containment.

  • Patent number: 5390461
    Abstract: A ranged, hollow, coffered rectilinear structure having integrally joined side member for hanging within a conventional, suspended T-bar subceiling matrix. Optionally the rectilinear structure may have a lip beneath the flange so that when two side members of two structures sit opposite one another on a conventional T-bar rail, both side members cooperate to reveal a space beneath the T-bar for mounting an additional track assembly, such track lighting, to the T-bar rail. Cross members in the hollow rectilinear structure add to its aesthetic appeal. A single cross member bisecting the rectilinear structure is formed so that it may be split, creating two smaller rectilinear structures having uniformly shaped, flanged side members for hanging within smaller T-bar matrices. By modifying the T-bar matrix and the rectilinear structure, a 3-Dimensional T-bar matrix is formed in the suspended ceiling, allowing rectilinear structures to be oriented on each other in both the horizontal and vertical planes.
