38 PRACTICAL SILO CONSTRUCTION 



clamps holding the sections together. Each section 

 can be raised and then the segments or sections 

 again fastened together, avoiding the use of any 

 tackle to raise the forms after each course, as two 

 men can lift the sections from the staging erected 

 for the workmen in placing the concrete. 



By having small segments or sections the forms 

 can be employed for many sizes of silos, by adding 

 or removing a section as demanded, which is a valu- 

 able feature to the contractor who must build all 

 sizes of silos. 



PLASTERED SILOS 



A successful type of silo construction has been 

 recently used; and that it is exceedingly practical is 

 shown by the illustration at Fig. 7, which illustrates 

 the method of arranging the vertical and horizontal 

 reinforcement and also the use of the wire lath that 

 is attached to same. 



This type of silo construction employs the placing 

 of " vertical rods around the circumference of silo, 

 ground plan, as per the spacing for diameter given 

 in Table IV. To this is added the horizontal or 

 "hoop" reinforcement, using " rods, and spacing 

 them as instructed in Table V. These horizontal 

 rods are tied with wire to the vertical rods at each 

 point they intersect, thus making a skeleton or "bal- 

 loon" frame of the silo. 



The vertical and horizontal rods are placed so 

 that they will be about 1J " from the outside of the
