SB Column Formworks

SB steel column form comprises a reinforced steel panel integrating a steel plate, common joist and sleeper.
Unlike existing column formwork, this system form is assembled on the floor in advance and installed on site using equipment.
While the existing column formwork repeats the entire processes of assembly and dismantlement, 
the SB steel column form is a stable and rapid method because it repeats only the process needed to fasten and loosen the Dywidag bolts of the triangle connector.

① Work efficiency in repeated formwork process is more than 8 times greater with the same labor requirements as existing column formwork. 
② The tie-less formwork does not use form tie, thereby reducing costs for installation and removal of form tie after removing forms and shortening the time needed.
③ No need to consider any restrictions in using a tower crane when using lifting equipment for column forms.
④ Less distortion by lateral pressure of concrete due to superior performances of materials used in column forms.
⑤ Clear concrete plane due to no connection joints on the column plane, unlike the Euro Form.
⑥ Less work for installation /dismantlement at higher levels. No requirement for lifting materials by workers.
⑦ Clean site and less loss of materials due to integrated column form.

If the site makes it difficult or restricts the use of a tower crane, set the lifting jig on an electronic forklift and move and install the L-shaped or channel-shaped column form after assembly.

Tower cranes cannot be used with the SRC column because of the upper beam. The column form is therefore installed using a lifting jig or crane. While existing methods build column forms by installing a column band to a Euro Form or plywood by hand, the Seobo device builds a pre-assembled SB column form so that work hours and labor costs are reduced to approximately 1/5.

SB-M reinforcements support lateral pressure of concrete by having large column works built on sleepers or column bands. This allows fastener-free column installation.
