Abstract: This invention is directed to a system for pouring concrete and thereby forming concrete floors, sidewalks and the like, wherein the forms used to retain the concrete in place remain as part of the permanent installation. The system is constructed basically of longitudinal rails, stakes and clips which fit snugly and securely together to form concrete retaining forms.

Abstract: Building frame units and building structures using such frame units as load-bearing wall sections or wall panels are disclosed. The frame units comprise hollow metal sections providing longitudinal frame members, end frame members and intermediate pillar frame members interconnected to form a rectangular skeletal frame. The top and bottom longitudinal frame members and the intermediate pillars are each composed of a pair of flanged channel sections assembled mouth-to-mouth and connected by C-cleats. The end frame members are each formed by a single flanged channel section having its open mouth presented outwardly. At least some frame units incorporate fittings such as windows and doors, but all residual spaces between adjacent frame members are closed by a sheet-like infill of plastics foam material providing a sealing and insulating barrier.

Abstract: A screed bar support stake and method are uniquely adapted to concrete screeding operations utilizing a vibratory-type screed. The stake is formed with means which allow it to be located after the concrete has been poured and is also adapted with means enabling the stake to be removed for reuse before the concrete hardens thus saving the cost of the stake. A mating drive member facilitates easy placement of the stake.

Abstract: An adjustable tile trim which can be constructed of tile itself, wood, plastic, or any suitable material, which has two inner surfaces substantially at right angles to each other, one of which abuts the front face of a cabinet, and the other surface fits over the terminating front edge of the tile, both surfaces being cemented. If the tile terminating edge is receded from the edge of a counter, a filler such as mortar is placed between the terminating tile edge and the face of the cabinet for structural strength and other purposes. Hence, the necessity of trimming the tile to the trim has been obviated in that the trim can accommodate any range of termination setback from the face of the counter and the trim is adjustable in a vertical plane to accommodate any thickness of tile.
