1. A method of manufacturing a waffle slab on a plurality of columns at intervals, the method comprising:
disposing a bottom mold separately on the plurality of columns and exposing joint heads of the plurality of columns from a top surface of the bottom mold;
disposing a plurality of first sets of beam bars separately on the bottom mold so that the plurality of first sets of beam bars are parallel to each other along a first direction, wherein the plurality of first sets of beam bars each comprises:
a plurality of first rebar cages disposed along the first direction at intervals, and
a plurality of first upper rebars and a plurality of first lower rebars that both penetrate through an inside of the plurality of first rebar cages and are respectively affixed to upper portions and lower portions of the plurality of first rebar cages;
disposing a plurality of second sets of beam bars separately on the bottom mold so that the plurality of second sets of beam bars are parallel to each other along a second direction, the second direction being different from the first direction, wherein the plurality of second sets of beam bars each comprises:
a plurality of second rebar cages separately disposed along the second direction; and
a plurality of second upper rebars penetrating through an inside of the plurality of second rebar cages and affixed to upper portions of plurality of the second rebar cages, wherein the plurality of second upper rebars are attached to parts of the plurality of first upper rebars that are located between two of the plurality of first rebar cages; and
providing and penetrating a plurality of second lower rebars through an inside of the plurality of second rebar cages and affixing the plurality of second lower rebars to the lower portions of the plurality of the second rebar cages;
wherein the plurality of second sets of beam bars are configured to intersect with the plurality of first sets of beam bars without interference, so that the plurality of first sets of beam bars and the plurality of second sets of beam bars together form a plurality of accommodation spaces therebetween.
