Abstract: The present technology relates generally to a platform and concrete composite slab system used as a building material. A platform, is formed from joined, substantially coplanar boards with connector plates partially embedded between the boards such that a portion of the connector plates extend above the platform's top surface. A reinforcing material (e.g., wire mesh and/or rebar) can be arranged on the prongs or other portion of the connector plates spaced above the platform and concrete is poured over the reinforcing material and allowed to cure, forming a reinforced concrete layer that encases the connector plates and reinforcing material. The connector plates act as standoffs and help to suspend the reinforcing material in the middle of the concrete layer to increase the strength of the reinforced concrete and to fixedly anchor and bind the concrete layer to the platform, so as to establish a composite action between the platform and the concrete.

Abstract: Disclosed embodiments include the production of construction plans upon planar surfaces such as studless walls near studless walls or traditional framing. Disclosed embodiments include specialized databases, cutting systems and printing systems useful for implementation of various plans upon planar surfaces sometimes used with hollow wall systems, sometimes constructed with bamboo or other fast growing sources of structural fiber, with the types of subject printing and cutting sometimes including architectural plans, structural plans, electrical plans, plumbing plans, mechanical plans, insulation plans, media plans, security plans and construction plans and details including those derived directly from various plans.
