SUPPORT FOR A GRAIN BIN FLOOR AND METHOD OF MAKING THE SAME

Abstract

A floor support for a grain bin floor made from a sheet of galvanized steel. The support having an upper flange or rail that extends upwardly from an upper shelf and is interposed between notches. A plurality of columns that extend downwardly from the upper shelf to a base to provide added stability to the support. A bend in the support which allows the support to stand upright without the need for additional supports.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

FIG. 1 illustrates a partial perspective view of a grain bin 10 having a concrete pad or foundation 12 and a circular wall 14, typically formed of corrugated sheet metal, with the supported grain bin floor system 16. The supported floor system 16 has floor panels which have perforations to provide for the passage of conditioning air, e.g., drying and/or cooling air. This air is conveyed into the bin by a fan (not shown), which may include a heater (not shown) located outside the bin, and enters the bin through an opening. The air passes into the plenum below the panels 26 and up through the perforations into and through the grain (not shown) stored in the bin on the supported floor system 16. The floor panels 26 are supported by a plurality of floor supports 28. The floor support 28 is made from a single sheet of galvanized steel that is cut and bent to create a stable support for the floor panels 26. The floor support has a plurality of upper flanges or rails 30 that are interposed by upper notches 32, the rails extending upwardly from an upper shelf 34. The upper rails 30 provide support across the center of the floor plank 26 while the notches 32 receive the outer edges of the floor plank 26 which are supported by the upper shelf 34.

Extending downwardly from the upper shelf 34 to a base 36 are a plurality of columns 38 having support wings 39. The columns are of any shape but a three sided triangular shape is preferred and provides support extending from the upper shelf 34 to the base 36 when loads are received on the panels 26 of the floor system 16. Interposed between the columns 38 are openings 40 which allow for air flow. The floor support has at least one bend 42 which is generally vertical when the floor support 28 is in an upright position. The bend 42 permits the floor support 28 to remain in an upright position without additional supports which prevents the floor support 28 from falling during assembly or usage. The bend 42 is of any angle which will provide upright stability to the floor support.

To form the floor support 28 a sheet of galvanized steel is bent along fold 44 and fold 46 to form the upper shelf 34 and the base 36. The sheet is also bent along fold 48 to form a flange that extends generally vertically from the upper shelf 34. Sections 49 are cut from the flange to form the notches 32 and in turn the upper rails 30.

Vertical cuts 50 are made that extend between the upper shelf 34 and the base 36 and horizontal cuts 52 and 54 are made in alignment with the upper shelf 34 and the base 36 respectively. The horizontal cuts 52 and 54 extend from the vertical cut 50 to the fold 56. Once cut the sheet is bent along fold 56 such that a hollow column 38 is formed that extends between the upper shelf 34 and the base 36. The top and bottom edges of wings 39 where the horizontal cuts 52 and 54 were made to form hollow column 38 may be welded to the upper shelf 34 and base 36 respectively to provide added stability. Finally, a notch is made in the base 36 and the sheet is bent along fold 58 to form bend 42. The upper shelf 34 and base 36 may be welded at bend 42 to provide added stability.

Accordingly, a floor support has been shown that is easy and economical to manufacture that may be used with a variety of floor panels and at least all the stated objectives have been satisfied.

Claims

1. A support for a grain bin floor, comprising a plurality of flanges interposed between a plurality of notches, the flanges extending upwardly from a shelf;a plurality of columns that extend between the shelf and a base; anda bend in the support that permits the support to remain in an upright position without the use of additional supports.

2. The support of claim 1 wherein the columns are generally triangular in shape.

3. The support of claim 1 wherein the columns support the shelf.

4. The support of claim 1 wherein the columns are formed by making vertical and horizontal cuts in a sheet of galvanized steel and bending the steel along a fold.

5. The support of claim 1 wherein the shelf and flanges are formed from a sheet of galvanized steel by bending the steel along folds and cutting the notches out of the steel.

6. A method of forming a support for a grain bin floor, comprising the steps of: providing a sheet of galvanized steel;bending the sheet along a first fold to form an upper shelf;bending the sheet along a second fold to form an upper flange,cutting notches out of the upper flange;bending the sheet along a third fold to form a base;making a plurality of vertical cuts in the sheet that extend from the upper shelf to the base;making a plurality of horizontal cuts that intersect the vertical cuts and are aligned with the upper shelf and the base;bending the sheet along a fourth fold to form a plurality of columns; andbending the support such that the support will remain upright without the use of additional supports.
