Disclosed are a height-adjustable inter-form concrete mold supporting system and method for in situ concrete construction. The system has a support member detachably disposed on a base plate. An inter-form truss is adjustably attached to the support member and holds formwork brackets to define concrete pour width. A plurality of like assemblages and attached formwork define concrete pour length and height of the monolithic concrete slab-on-grade foundations or flooring in situ.

I claim: 1. An inter-form concrete framing system comprising, in combination,a) an inter-truss member comprising: a first tube comprising a longitudinal axis defining a length and comprising two open ends, an internal surface, an external surface, and a circular, threaded opening through the external surface and the internal surface; a second tube comprising a longitudinal axis defining a length and comprising two open ends, an internal surface, and an external surface; a triangular plate defining a uniform thickness and comprising a base, an apex, a front surface, a back surface, a central axis between the triangular plate base and apex, and a circular, threaded opening having a diameter equal to the first tube circular, threaded opening, extending through the uniform thickness at a location centered on the triangular plate central axis near the apex; wherein the first tube external surface is attached to the triangular plate back surface along the triangular plate central axis such that the triangular plate base can be positioned above the triangular plate apex when the first tube longitudinal axis is positioned parallel to the triangular plate central axis, and wherein the first tube circular, threaded opening is aligned with the triangular plate circular, threaded opening; wherein the second tube external surface is attached to the triangular plate base and the first tube external surface such that the second tube longitudinal axis is transverse to the triangular plate central axis;b) a vertical support element comprising a top end and a bottom end, and a uniform diameter sized to be received into the first tube along first tube longitudinal axis;c) a base plate sized to receive and fixedly hold the vertical support element bottom end;d) means for attaching vertical angle brackets to each second tube open end; ande) threaded locking means sized to be received through the aligned first tube circular threaded opening and triangular plate circular threaded opening for adjustably positioning and attaching the inter-truss member to the vertical support element;whereby at least two inter-truss members and associated vertical support element, base plate, means for attaching vertical angle brackets to each second tube open end, and threaded locking means sized to be received through the aligned first tube circular threaded opening and triangular plate circular threaded opening for adjustably positioning and attaching the inter-truss member to the vertical support element for each such inter-truss member can be arranged at a predetermined interval above an earthen substrate, vertical angel brackets, mounting and opposed framework can be attached to each inter-truss thus defining a space, and concrete can be filled into the defined space within the vertical angel brackets, substrate and formwork, thus eliminating voids and possible corrosion to structural concrete reinforcements from intrusion of moisture from the substrate.
