摘要:
A flooring system including horizontal metal framing members, for example, C-joists, U-joists, open web joists, HAMBRO or other metal frame systems that support a reinforced, lightweight, dimensionally stable SCP panel. The flooring system is non-combustible, water durable, mold and rot resistant, termite resistant and is capable of resisting shear loads equal to or exceeding shear loads provided by plywood or oriented strand board panels. The panels employ one or more layers of a continuous phase resulting from the curing of an aqueous mixture of inorganic binder, for example, calcium sulfate alpha hemihydrate, hydraulic cement, an active pozzolan and lime. The continuous phase is reinforced with glass fibers and contains lightweight filler particles, for example, ceramic microspheres.

摘要:
The present invention provides a system of jointing and finishing plasterboard sheets. The system comprises adjacently abutted first and second plasterboard sheets and a connective material. The connective material is applied to a region at or near the side edge portions of the first and second plasterboard sheets and which securely joins the side edge portion of the first plasterboard sheet to the side edge portion of the second plasterboard sheet. There is also provided a joint filling compound and a finishing compound, which are optionally also applied to the region of the first and second plasterboard sheets.
摘要:
A single crystal ingot is cut to an axial direction so as to including the central axis, a sample for measurement including regions [V], [Pv], [Pi] and [I] is prepared, and a first sample and second sample are prepared by dividing the sample into two so as to be asymmetrical against the central axis. A first transition metal is metal-stained on the surface of the first sample and a second transition metal different from the first transition metal is metal-stained on the surface of the second sample. The first and second samples stained with the metals are thermally treated and the first and second transition metals are diffused into the inside of the samples. Recombination lifetimes in the whole of the first and second samples are respectively measured, and the vertical measurement of the first sample is overlapped on the vertical measurement of the second sample. The boundary between the regions [Pi] and [I] and the boundary between the regions [V] and [Pv] are respectively specified from the overlapped result.

A foundation system includes metal framing members that support a reinforced, lightweight, dimensionally stable cementitious panel. The foundation system is non-combustible, water durable, mold and rot resistant, and termite resistant. The panels employ one or more layers of a continuous phase resulting from the curing of an aqueous mixture of inorganic binder, for example, calcium sulfate alpha hemihydrate, hydraulic cement, an active pozzolan and lime. The continuous phase is reinforced with glass fibers and contains lightweight filler particles, for example, ceramic microspheres.
摘要:
This invention relates to a structural cementitious panel (SCP) panel able to resist lateral forces imposed by high wind and earthquake loads in regions where they are required by building codes. These panels may be used for shear walls, flooring or roofing or other locations where shear panels are used in residential or commercial construction. The panels employ one or more layers of a continuous phase resulting from the curing of an aqueous mixture of inorganic binder reinforced with glass fibers and containing lightweight filler particles. One or more reinforcement members, such as mesh or plate sheets, are bonded to at least one surface of the panel to provide a completed panel that can breathe and has weather resistant characteristics to be capable of sustaining exposure to the elements during construction, without damage.
