Abstract: A composite building construction system comprising a frame, an expanded wallboard, and a concrete layer. The wallboard comprises an outer portion and inset portion wherein the wallboard is attached to the frame with the outer portion covering an exterior side of the frame and the inset portion is disposed within the frame. The wallboard thus provides exterior and interior insulation for the system. The concrete layer is sprayed on to the outer portion of said wallboard, forming a strong durable composite construction system. One or more rebar supports may be attached to the frame at the exterior side by key bolts and are spaced apart from the wallboard. A wire grid may be attached to the key bolts whereby the grid and the rebar supports provide a support structure for the concrete layer. The frame comprises steel and the wallboard comprises insulative expanded polystyrene.

Abstract: A wall forming system that uses a pair of panels in combination with a furring strip assembly and retainer The pair of panels are placed in spaced relation using the combination of the furring strip assembly and the retainer wherein the furring strip assembly holds the exterior of the panels while the retainer is disposed between the panels to hold them at a predetermined distance. By holding the panels at a predetermined distance concrete is poured within the cavity formed between the panels to create a wall.

Abstract: The floor member, in the form of a floor tile or a floor plank, that is formed of a flexible, non-rigid material, has a bottom portion formed with a plurality of moisture dispersal pathways that lead toward peripheral side edges of the bottom portion. The moisture dispersal pathways permit any moisture that develops between a floor base and the bottom portion of the floor member that is installed on the floor base to flow in the moisture dispersal pathways toward at least one of the peripheral side edges of the bottom portion, for passage beyond the one peripheral side edge of the bottom portion. Adjacent tiles of a floor tile installation have communicable moisture dispersal pathways such that moisture is not entrapped below the floor member and can migrate through the communicable pathways to an outermost peripheral side edge of the floor tile installation for dissipation of moisture into the ambient air.

Abstract: A prefabricated building component, e.g. for incorporation in a wall, a floor, a roof or another building component, comprises a frame formed by lengths of lumber with heat insulating foam material provided in spaces between the lumber so as to form a heating insulating barrier. To reinforce the frame against racking forces, a reinforcement sheet of fiber reinforced composite material is provided on the barrier and the lumber at least one side of the frame.

Abstract: A waterproof-sheet type of roofing shingle comprises a belt-like tape attached to a bottom side of the roofing shingle facing a concrete slab. The belt-like tape has air passages for reducing a pressure of steam or vapor generated from concrete. The air passages are formed by projections or grooves and adapted to be in communication with air passages of an adjacent roofing shingle. The air passages are eventually in communication with an ambient atmosphere so as to vent the steam or vapor to the atmosphere, and therefore, bulging of waterproofing material is prevented from occurring.

Abstract: A rigid backerboard for replacement or substitution for a cementuous backerboard. The board is formed of a compression molded plastic material, preferably nylon which is relatively thin, yet rigid. The board is embossed on both of its principal (upper and lower) surfaces to maximize surface area for contact with adhesive materials. The embossment on at least one of the sides is rectilinear, facilitating the cutting of standard sized rectangular panels into smaller rectangles. The embossment on the opposite side is designed to maximize adhesive contact area, a diamond pattern being preferable.

Abstract: An improved roll roof membrane for use in commercial applications, i.e., flat and low pitch roof structures, and a method for the preparation thereof. The roof membrane comprises a support sheet, and top and bottom layers comprising APP modified bitumen, the top APP modified bitumen layer having a selvage edge disposed along one side of the membrane and the bottom APP modified bitumen layer having a second selvage edge disposed along the opposite side of the membrane. Each of the selvage edges have a series of embossed ridges and valleys adapted to accept adhesives, the valleys extending substantially through the APP modified bitumen layer to the support sheet. The membrane exhibits excellent peel strength with an adhesive, thereby eliminating the need to use a torch during installation in commercial roofing applications.

Abstract: A system of construction based on the use of polystyrene boards for constructing partition walls as well as extradoses, these said boards being equipped with grooves for electrical and plumbing ducts, as well as for the formation of structural ribs, while their vertical edges are equipped with grooving and tonguing for their interconnection. Boards are put into place between the floor and ceiling, with the interposition of perimetrical perimeter strips made of the same material. Plaster with an additive is then used to coat the surfaces of the said boards as a finish which forms an adhesive paste. Vertical fixing strips facing each other on opposite sides play a role in the emplacement of the boards, while plastic mesh is placed at the joints between the boards and walls, to improve the joint and prevent cracks.

Abstract: The present invention pertains to a long-span decking panel. The long-span decking panel is used, for instance, to span the space between girders to create a roof or a composite floor. The panel has a flange member having a first edge and a second edge. The edges are at least 11 inches apart. The flange member defines an essentially flat unbroken soffit except for a series of stiffening ribs running transverse to the edges. The stiffening ribs provide sufficient rigidity to the flange member to prevent it from buckling along its length. The long-span decking panel also has a first web member which is integrally jointed and extending obliquely form the first edge. There is also a second web member integrally joined and extending obliquely from the second edge. The web members can be of any desirable length depending on the decking situation.
