The composite structure can be quickly constructed to create columns and beams.

Abstract

The design refers to a rapidly constructed combined structure (3) to create a column-beam consisting of at least two sets of reinforcing bars (31) fixed by positioning details (32) and mesh formwork details (33). Each set of reinforcing bars (31) consists of reinforcing bars (311) welded to surrounding details (313) and connecting details (314). Each surrounding detail (313) surrounds the reinforcing bars (311) as each connecting detail (314) extends inclined between any two adjacent surrounding details (313), thus constructing a continuously bent reinforcement (312) fitted tightly around the reinforcing bars (311). The sets of reinforcing bars (31) have different dimensions so that one set of reinforcing bars (31) is nested inside a larger set of reinforcing bars (31).Therefore, the steel beam assemblies (31) are processed and constructed as a whole with the help of welding and quickly combined with the positioning details (32) and mesh formwork details (33) to reinforce the strength, which allows the beam columns to be quickly constructed on the construction site.
