. Concrete silos; their advantages. Silos; Concrete construction. 82 Concrete Silos. Section of Mold at Chute: frame are entirely separate from the wall forms, the latter depending entirely for support on the 3 feet of wall when closed by the lower circle of forms; and as the upper section of the staging frame is always above the wall forms the same outfit will, of course, answer for varying diameters of silos. These silos are reinforced with triangle mesh rein- forcing, the selection of the reinforcing depending upon the size of the silo and being selected usually to provide suf- ficient strength with- out placing any addi- tional wires. The company recommends a 38-inch width, this allowing a 2-inch lap between courses. After a circle has been poured and it is desired to move up the lower section of the forms, the bucket at the end of the derrick is taken off and a wooden seat is suspended from the hook in its place. By this means a man is lowered to the outside of the forms and removes the clamps which hold the two sections together. The forms are drawn up by men on the scaffold by means of hooks which engage in holes „ in the angle iron welded to the top of the forms. The in- Monsco Roof Form. side forms are m a n i pulated.
