Abstract
Abstract Pre-formed building studs and a form utilizing such studs for receiving a flowable, hardenable material, for example cementitious material including concrete, for forming building structures such as foundations, walls, floors, roofs, etc. The studs allow passage of the cementitious material therethrough when poured into the form. The form comprises a hollow wall that includes two opposing form panels connected to preformed, flow-through studs, forming fluidly connected sections between each stud. As the cementitious material fills the hollow wall, each section is fluidly joined, allowing the cementitious material to harden and cure to form an integrated solid wall. Each stud includes two elongated parallel members having a flow-through web structure extending between the elongated members. By selecting form panels that are thermal insulators and waterproof, the resulting structure has improved moisture resistance and thermal insulation properties, both during and after the curing process.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
244 words
A form system for fabricating building structures from a hardenable material, the material being hardenable from a flowable state after a time period, said form system comprising: a first plurality of substantially solid panels being substantially planar and being arranged edge to edge to define a first planar surface; a second plurality of substantially solid panels being substantially planar and being arranged edge to edge to define a second planar surface, said first surface being substantially parallel to and spaced apart from said second surface, said first planar surface and said second planar surface defining a space into which the hardenable material is to be poured; and a plurality of studs, each of said plurality of studs including: a first elongated member, a second elongated member being spaced apart from and parallel to said first elongated member while being in registry with said first elongated member, and a foraminous web sheet of mesh material having a plurality of evenly distributed openings therethrough, said foraminous web sheet extending between and attached to said first elongated member and said second elongated member, said foraminous web allowing the hardenable material in the flowable state to flow therethrough, each of said plurality of studs being positioned in said space defined by said first and second plurality of panels with said first elongated member thereof abutting and being fixed to said first planar surface and said second elongated member thereof abutting and being fixed to said second planar surface.
Claim 2
Dependent Claim
