CHAPTER X 



THE MONSCO SYSTEM 



This is a system of construction with metal forms 

 controlled by the Monolithic Silo and Construction 

 Company, Chicago. These forms are made of No. 16- 

 gauge galvanized sheet steel and are held true to shape 

 by curved steel angle irons welded to the sheet, which 

 reinforce the steel plates at the edges and through the 

 middle. The forms are made in sections 3 feet high 

 and the circumference of the silo is divided in 5 to 8 

 segments, according to the size, this including the form 

 for the chute, which, if desired, is cast at the same time 

 as the walls of the silo. Sufficient forms are used in 

 an outfit to form two complete circles around the silo. 



In starting the construction of the walls, one circle 

 of these forms is placed on the foundation and poured 

 full. The next circle of forms is then clamped to these 

 and poured. This 6 feet will usually constitute a day's 

 wort. The next morning the bottom circle of forms 

 is raised to the top and filled, after which the section 

 below is raised and filled, this constituting the second 

 day's work, and the operation is repeated until the 

 desired height is reached. In other words, the operator 

 is always pouring into a 3-foot section of mold firmly 

 clamped to another 3-foot section filled with concrete, 

 the concrete set sufficiently to eliminate the possibility 

 of a wall fracture. 



These silos have 6-inch walls, the thickness being 

 the same from top to bottom. Forms are made for 

 diameters of 10, 12, 14, 16, 18 and 20 feet.
