Abstract: A novel insulated wall structure is formed with upright hollow thermoplastic extrusions connected together in a row, with the extrusions presenting a row of compartments (15,22,30) adapted to receive concrete (39) extending along the length of the wall structure and a row of compartments (16,23,33) containing or adapted to receive insulation (38) material also extending along the length of the wall along side or in parallel with the row of concrete receiving compartments (15,22,30) whereby when the compartments (15,22,30) adapted to receive concrete (39) are filled with concrete (39) and the insulation (38) receiving compartments (16,23,33) are filled with insulation (38) the insulation (38) in said insulation (38) receiving compartments (16,23,33) is positioned to block heat transfer through the wall.

Abstract: A thermoplastic wall forming member is provided with rails for securing a wiring channel interiorly of a hollow structure to be formed by the wall forming member and other wall forming members.

Abstract: Elongated extruded thermoplastic hollows structural components of rectilinear cross section formed for interlocking assembly for use in erecting a modular building on a supporting base, characterized in that each said component being a coextraction of a substrate including reprocessed plastic material and a thin smooth protecting thermoplastic skin covering wall surfaces of said component which are exposed when same is interlocking assembled with mating components, each said component being cored to provide a predetermined pattern of spaced holes along the length of the walls thereof which become internal walls when same in interlockingly assembled with mating components and the holes of mating components being in registration to provide internal flow passages therebetween with the corings providing a source of substrate reprocessed plastic feed stock.

Abstract: Extruded hollow thermoplastic structural components of rectilinear cross section formed for interlocking assembly with mating components for use in erecting a modular building characterized in that said components are extruded from PVC material which includes a smoke retarding agent which is covered by a skin (3) on surfaces exposed to the environment.

Abstract: Thermoplastic structural components utilized within building construction as permanent formwork. The components formed with openings along a length which serve to allow concrete to flow from one form to adjacent forms. Thus, filling the components forming a surrounding wall of a building. The openings allow for air circulation within components forming a roof assembly. The components are co-extruded with a protective skin along outer surfaces thereof. Grooves are provided along the length of the component for mating with interlocking flanges of a box connector. Planar spaced walls are provided within each component and have a series of openings along a length thereof.

Abstract: The invention is for a thermoplastic structural system, structural components therefor, and method of producing same in which the structural components are extruded from a thermoplastic material containing a reinforcing constituent flowable through an extrusion die, the structural components being configured for interlocking interconnection.

Abstract: A molded cladded panel comprises on the underside thereof a bearing surface formation for bearing on an underlying support surface and latches for latching the panel to an underlying support surface, the panel having a profile configured to provide a desired appearance rising above the bearing surface formation, a nib formed on the profile for interfitting with adjoining panels whether in end-to-end or side-by-side relation, and a latched keeper member for latching engagement with the panel latches.

Abstract: The disclosure relates to a vacuum sizing device for cooling and sizing plastic extrusions immediately downstream of the extrusion die. The device includes a plurality of pairs of upper and lower sizing elements which are clamped between upper and lower backing members. The elements are shaped to define a passageway through the sizing device having a cross-sectional shape and size corresponding to the required profile shape and size of the extrusion. Vacuum chambers and cooling chambers are provided in the sizing elements.
