Column modular molds are constituted from outer wings, fittings including pin, wedge and clamp .

Kinds of Molding Column :

A- Mold of Column with Square or Oblong Sections

With the application of modular parts, one concrete-based column can be molded and implemented with oblong or square section. One mold of column has been constituted from panels, outer wings (corners) and/or punched angled irons, shackles and fittings including clamp, and wedge.
Outer wings are of beveled type and create bevel in corner of columns. If corner of columns is used from punched angled iron, corner of columns will be in the form of pointed. For sections smaller than 70 x 70 cm, shackles of column with pipe section (tubular shackle) are used while for sections larger than the said figure, u-shaped section (u-shaped shackle) should be applied.
For preventing mold of columns from misshaping, it is suggested that size of height of outer corners should not be similar to middle panels.

Tubular Shackle                      U-shaped Shackle

 Mold of Column with Circle-Shape Section
For implementation of column with circle-shaped sections, specific molds are designed and manufactured with due observance to the size, dimension and height of column. Usually, sections of circle-shaped sections are constituted from two 180 degrees segments and the above mentioned clamps are connected by shatterproof steel clamp to each other. These clamps are durable and resistant which are placed in their locations by a strike of hammer.
Molds of circle-shaped column are divided into two types in terms of dimension:

Sections with dimension larger than 100 cm Clamps Section with Dimension Smaller than 100 cm   
 
Table below shows items required for mold of column measuring 50 x 50 cm for height less than 3 meters
