ABSTRACT:
Disclosed is a precasted wall/column module including a hollow body formed from a four-side outer frame and an inscribed round pipe. The outer frame has an upper end forming a first axially projected flange extending along an inner edge of the upper end and a lowered outer edge extending around the first flange, and a lower end forming a second axially projected flange extending along an outer edge of the lower end and a lowered inner edge extending along an inner side of the second flange. Axially extended insertion holes are correspondingly formed at every corners of the upper and lower ends to receive insertion bars for connecting the modules to one another. A thinned area can be selectively provided on either side of the outer frame. Two semicircular openings are separately formed at upper and lower edges of each thinned area and a plurality of round holes are spaced between the two semicircular openings.
