Abstract: A light steel framing construction technique for light gauge load bearing wall type buildings uses specialized brackets to suspend poured slab floors. Multiple stories of the building can be erected without waiting for individual concrete slab floors to be poured and set at each story. During construction, a building is protected from torsional warping, such as may be occur under wind loads, by a series of lateral and diagonal bracing structures at each level affixed in a plane perpendicular to the load bearing elements. Multiple concrete floor slabs can be poured sequentially or simultaneously, as desired, during the construction process.

Abstract: A system of building concrete homes and apartment buildings. The system creates a structure that is well insulated and that is very practical and economical to build. The system uses standard components such as wall ties, concrete forms, rigid foam insulation, and concrete, all of which are readily available in the market today. The system creates a building that is insulated and thermally broken at its structural connections such that use in temperate and colder climates is possible. Presently concrete construction finds only limited use for the construction of single family and multi-family housing. The system is economical to construct when compared to wood frame housing.

Abstract: A distribution angle plate for a concrete floor system in a multi-level building is disclosed. The plate helps to create a joist bearing point at the interior surface of a vertical structural wall and proximate the top portion of the vertical structural wall. Decking may be laid flat over the top surface of the steel joist and the top surface of the vertical structural wall. This allows the decking to be screwed, welded, or shot directly to the top surface of the vertical structural wall and the top of the steel joist on the same horizontal plane. This also provides for a direct shear attachment at the perimeter of each vertical structural wall. Any height of concrete can then be poured on top of the decking, steel or wood, on a flat continuous plane. This creates a continuous solid mass between vertical structural walls in multi-story buildings, with no voids between floors.

Abstract: An apparatus and method for coupling separate series or stacks of structural or shear walls of a multistory building are disclosed. The method comprises constructing a plurality of stacks of shear walls and attaching a rigid coupling member to the top of at least two of the stacks of shear walls between the stacks such that the walls are connected to the rigid coupling member and move together with the coupling member. The apparatus is a rigid coupling member, which may be a beam, such as an I-beam or rectangular beam, made from poured concrete and reinforcing steel. The coupling member may also be a wall of poured concrete and reinforcing steel. The attached rigid member acts to connect the tops of independent stacks of shear walls typically used to build multistory buildings, thereby creating a flexural moment at the top of the building that helps the building resist lateral loads.

The bracket includes a base from which a pair of side walls upwardly extend. The track wall includes a base from which a pair of side walls upwardly extend, functions as sole and top plates, and sits attachingly in the bracket. The stud extends attachingly from the bracket. The optional base plate, when present, sits attachingly in the bracket and distributes load of the stud. The at least two diagonal braces extend attachingly diagonally outwardly from the pair of side walls of the bracket, respectively.

Abstract: A method of forming a portion of a monolithic concrete building provides for two-dimensional support of horizontally extensive portions of the building at all times and thus reduces the strength required of the vertically extensive supports. The method employs flanged wall members having horizontal extents substantially equal to the selected room size. Each of the wall members has at least one flange extending horizontally towards a parallel facing wall member by about ten to twenty five percent of the intramural separation between the walls of the room being constructed. Horizontal floor or ceiling slabs that link the horizontal flanges may be cast in situ using a form plate supported by a temporary trussed joist.

Abstract: An improved structural framing system and associated method of construction is disclosed wherein an open web dissymmetric steel beam fabricated having a plurality of trapezoidal openings formed along the web thereof between a narrowed, thickened top flange and a widened bottom flange is horizontally disposed and supported between adjacent vertical columns erected on conventional foundations. The dissymmetric beam is preferably fabricated from a standard rolled, wide flange beam split longitudinally according to a specific cutting pattern to produce substantially identical open web beam sections having a single wide flange. A flat bar plate is then welded along the open web beam section to provide the top flange and thereby produce the dissymmetric beam for use in the present system.
