ABSTRACT:
Precast or poured columns are erected in a plurality of rows. Precast concrete beams are placed on temporary supports between the columns in each row. The beams are slightly shorter than the distance between the columns and are not supported by the columns. Precast concrete floor slabs are placed between the precast beams of adjacent rows, with the ends of the slabs partially overlapping the beams. Temporary forms are placed around the upper portions of the columns and under the end portions of the beams and the adjacent floor slabs. Concrete is then poured to form monolithic concrete members extending over the upper sides of the beams and filling the spaces between the ends of the slabs and also the spaces between the ends of the beams and the ends of the columns for uniting the beams, slabs and columns. After sufficient curing of the poured concrete, the forms and the temporary supports are removed. The columns support the composite beam structures comprising the monolithic concrete members and the precast beams, which support the precast floor slabs. Reinforcing members are preferably embedded in the monolithic concrete members. The method has the rapid erection advantage of a precast system, combined with many of the advantages of poured-in-place concrete, including rigidity and freedom from close tolerances.
