Large knots weaken weak-en joists especially if near the lower edge. Small holes in floors may be covered with pieces of sheet metal, and floors with cracks should be covered with tight flooring with paper between. Tight floors are necessary to keep gases in during fumigation. Concrete floors in bins for long time storage need to be at least 8 inches above the ground with hollow tile or course gravel underneath. under-neath. It is a good plan to cover the concrete floors with moisture-proof moisture-proof kraft paper or loose boards or to paint them with two coats S asphalt-aluminum paint. i With the increased loan rate and the provision to store wheat under the marketing quotas, many farmers are now planning extra wheat storage space on their farms, says Alphonzo Christensen, chairman of the Cache county AAA committee. He offered as a suggestion several sever-al fundamentals of good storage. stor-age. He said the emphasis for a good bin should be on foundation founda-tion footings which are large enough to prevent settling on moist soils one square fost of surface bearing on the ground for every 60 bushels of wheat. Footings need to be wider -on soils that are not firm Depth of foundation should be 12 inches to as much as 36 inches, to protect against leaning, and undermining by water, rodents and livestock. Many state colleges have determined suitable depths for different areas af the state. Fifteen or eighteen inches above the ground is a good height for foundations. Small and medium-sized medium-sized bins are often put on semipermanent semi-permanent foundations such as stone or concrete blocks. j Floors and joists should be designed de-signed according to tables of weight-carrying capacity. Such tables may be formed in the U. S. Department of Agriculture bulletin, bul-letin, "Wheat Storage in the ever Normal Granary.'' Copies of this bulletin may be obtained from Bin walls can be made of various var-ious materials such as boards, plywood, metal, or masonry, but must be strong enough to resist bursting pressure. Cometimes added ad-ded strength is provided by wire or cross ties. Walls must be tight to keep out moisture and to make fumigation feasible. Prefered construction for wide-fram bins jcall for two thicknesses of boards, with waterproof paper between. These should be placed on inside of studs. In region of blowing show the joint at the eyes should be tight and there should be arrangements ar-rangements for closing ventilators or any other opening through, which snow might enter. |
