The column can be cast to the underside of the beams. A collar of formwork can be held around the cast column to complete the casting and support the incoming beam. False work

A reinforced concrete column is a structural member designed to carry compressive loads, composed of concrete with an embedded steel frame to provide reinforcement. For design purposes, the columns are separated into two categories: short columns and slender columns.
In the illustration of the column formwork above, the 'column clamps' are closer together at the bottom.

The 90 to 200m 2 3D printed homes take around five to seven days to print, compared to a timber frame which would take up to 16 weeks in the same area. [22] ICON also completed a project in March 2020 for seven 3D-printed homes in Austin, Texas. Each 400 ft 2 home was printed in just 27 hours using ICON's Vulcan printer. The first residents ...
