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.
Abstract: A molding assembly which includes a length of molding, a pair of retainers, and a plurality of optional L-shaped brackets is disclosed.

The retainers each include an inwardly and rearwardly directed hook which is frictionally engageable with a respective yieldable fastener. Successively arranged slots are disposed along the entire length of each retainer for receiving fasteners therethrough to secure the same to a mounting surface. The L-shaped brackets have a plurality of through bores passing therethrough.
Abstract: A junction for connecting a steel member to a structural member, such as a beam in a steel framed construction to a column in a reinforced concrete construction, a steel framed concrete construction or a steel framed construction. Junction hardware connect to the steel member and a rod-like orthogonal metal connector is provided in concrete structural members. The elements are connected by tightening bolts or by screw joints through a coupler. Since the metal connector is in a form of rod, the concrete member has a high packing property. Field welding work is omitted by connecting the metal connector to the junction hardware by a bolt connection method or by a screw joint method to facilitate assembly.
Abstract: This invention relates to an apparatus and method for creating tiling networks with geometrical and ornamental patterns and designs without using tile. The networks consist of units which may be manufactured in whatever patterns or designs that are desired. The network units are pre-manufactured to form the required ornamental pattern or design and may be assembled on site on a level surface. When assembled, a series of cavities are created. The cavities are divided by the walls of the network units. The top surface of the walls of the network units are an integral component of the pattern or design created. The cavities and the patterns formed by the top surfaces of the network units comprise the ornamental pattern or design. The cavities are filled with a material in order to make the ornamental surface relatively level. The cavities may be filled with materials of different colors to enhance the pattern or design.

Abstract: A method and apparatus are utilized to produce panels which simulate overlapping red clay roof tile. The panels are fire resistant, impact resistant, opaque, lightweight, and have sufficient strength to support fully the weight of an individual walking on the tile.
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.
Abstract: A method of forming a concrete column capital using a flexible tension membrane material in place of the traditional rigid panels currently used for this purpose, is described. A flexible tension membrane material is attached to an opening in a panelized flat slab formwork deck located directly above a pre-existing concrete column. The membrane forms a bag-like container which contains and supports the wet concrete, and serves to form a column capital between the column and the flat slab above. Also disclosed are methods for anchoring the flexible tension membrane capital form to a panelized flat slab formwork deck.
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.

Abstract: A plastic liner for protecting concrete manhole interior surfaces from corrosion wherein the liner includes provisions for creating a strong mechanical lock between the liner and the interior surfaces. A side of the liner which includes the provisions has a plurality of raised hollow projections with spaced sections. The mechanical lock is created when concrete is poured against the side of the liner with the projections. The concrete at least partially enters the hollow portions and fills spaces between the projection sections. The projections also intersect to enhance the mechanical lock by preventing bulging. Liner sections cover essentially all of the manhole interior surfaces. Forming a liner section by rotationally molding the plastic and cutting gaps into the projections is also disclosed.
Abstract: A method of erecting a foundation structure for a building substructure, in which joists including a horizontal web interconnecting upright side flanges on either side, are positioned butt end against butt end and are fixed in position at a distance of a few centimeters above a substratum. Gravel, macadam or other back fill material is then positioned against the external face of each side flange, whereupon concrete is poured into the joists and is allowed to partly flow downwards, through apertures formed in the joist webs, and onto the substratum.
Abstract: An architectural panel system for assembling geodesic-like structures in which three or more corrugated panels of relatively thin material are joined along their sides to form a polyhedral angle. The corrugations may be formed in the panel surface or along side flanges provided for attaching adjoining panels together, or both. Corrugations in the side flanges serve to interlock adjoining panels together directly or through use of interlocking channel members. Surface corrugations in triangular and pentagonal panels for spherical domes are formed perpendicular to the edges of the panels and converge along load distribution grooves formed in the panel surfaces from the corners of the panels to their centers. Corrugations in the panel surface and along the side flanges are intercorrugated relative to one another for more strength and stiffness. The panels are preferably formed using polycarbonate plastic material.
