Concrete Silos 



the studding, placed with the long dimension around 

 the silo. 



In estimating the quantity of metal lath required for 

 a double wall silo, the table given in this chapter can 

 be used, remembering to use just twice the amounts. 



Silos are also made from the various special pat- 

 ented types of metal lath now on the market. With 

 some of these it is found to be possible to erect the 

 silo without the use of the temporary studding previ- 

 ously described. 



One such is the product known as Hy-Rib, made by 

 the Trussed Concrete Steel Company, Youngstown, 0. 

 This is a herringbone metal lath with deep corrugations 

 or ribs pressed in it at regular intervals, these giving 



Hy-Rib Acts As a Form and Reinforcement for the Concrete. 

 Note the temporary wood frame for metal sheets. If the 

 wood frame-work is to be removed the sheets must be wired 

 together. If 2x4-inch rafters are to be left the metal may be 

 nailed lightly to them and the cross boards only removed. 

 This is undoubtedly the quickest and cheapest method.
