Abstract Apparatus for forming concrete beams integrally with concrete floors comprising an elongated beam form with bottom and side walls and with flanges extending outwardly from the top of the side walls. A pair of rods projected upwardly through holes in opposite flanges, are tied by a steel strap to prevent spreading of the side walls when concrete is poured into the form. After the concrete sets, the rods are pulled out, the form stripped, and the strap left in place. The elongated beam forms have end portions, where the lower walls are stepped down and the side walls stepped outwardly, and a pair of aligned beam forms is joined by an adjustment form section which lies within the stepped end portions of the beam forms.

Apparatus for forming concrete structures including regions forming integral beams, floors, and columns comprising: an elongated beam form with a bottom walL and side walls extending in a generally upward direction from said bottom wall, the side walls at one end of said form extending along the surface of an imaginary cylinder of predetermined diameter up to locations on diametrically opposite sides of the cylinder, and said side walls have outwardly extending flanges at their extreme ends; and a column form for joining to said outwardly extending side wall ends of said beam form to enclose the rest of said column region, to provide continuous beam and column regions, said column form extending 180* along the surface of an imaginary cylinder of said predetermined diameter, and said column form having outwardly extending flanges for joining to the flanges on said beam form side walls.
