PRACTICAL SILO CONSTRUCTION 



bolted to the uprights. The hoops or wires extend- 

 ing horizontally around the silo wall are tied to the 

 angle bars, thus forming a continuous reinforcement 

 entirely over the wall of silo. By referring to the 

 drawing at Fig. 12 the advantages of this type of 

 reinforcement is easily seen ; and, as it is simply con- 

 structed, there is nothing to prevent its general use. 

 For the vertical reinforcing rods there is nothing 

 as satisfactory as those of !" in diameter. These 

 weigh .375 of a pound to the foot; and, when spaced 

 around the circumference of the silo, as explained in 

 the following table, make a reinforcement that will 

 support its own weight and the reinforcement added 

 to same without bending or becoming displaced, as 

 is usually the trouble with vertical reinforcement 

 formed of wires. 



TABLE IV 



VERTICAL REINFORCEMENT AND SPACING f " RODS. 



The height of silo is given in the first line, and 

 the number of rods to use, spaced at the proper dis- 

 tance apart, in the second line. Thus, in a silo 10 ' 

 in diameter and 25' high, one f" rod is used for
