Method of constructing precast concrete building with ductile concrete frame

摘要

Method is disclosed for the construction of a concrete building utilizing precast floor slabs and in situ cast concrete columns, in which method, the forms for the columns are utilized to support the precast concrete floors and the columns are cast thru holes provided in the floor slabs, with the reinforcing of the slabs continuous thru the holes, and reinforcing for the columns continuous vertically for multi level buildings. In addition, means is disclosed for casting beams between the columns to provide a concrete frame which is made to function as a composite beam with the floor slab. In addition, means is disclosed to utilize the foldable concrete walls to provide lateral stability during the erection.
