Abstract

A floor panel system for use in grain storage and drying bins is disclosed which uses modular perforated floor panels each of which is hemmed across the width of the panel at predetermined points along its length so that panels of various lengths can be provided readily by breaking standard panels along any appropriate selected hem. The hems also reinforce the panels. Each modular floor panel may have a complete hem at one end and a half hem or flange at the other end such that the panels can be readily aligned and interlocked end-to-end by inserting the half hem or flange of one panel into the full hem of a succeeding panel. A transverse clip may be used to hold together two abutted modular floor panels end-to-end and for reinforcing purposes where high floor loads are contemplated. Adjacent panels are abutted together along the sides and are held together by fitting the side lips into rails or support beams. These rails in turn are resiliently gripped in notches cut into the top edges of the side walls of V-shaped posts. The beam can be fit into these posts and resiliently held by the legs of the post, as when the post is squeezed and then released.

Claims

1. A modular grain bin floor comprising in combination:

(a) a plurality of elongated modular grain bin floor panels each having opposite side edges and opposite ends, each of said panels formed of bendable sheet metal and including a plurality of modules each located between said side edges, said modules of each panel being disposed in end-to-end relation to one another and forming a substantially continuous upper surface extending the length of said panel between said opposite ends, a reverse-bend hem of said sheet metal extending transversely of the respective panel between and integrally joining each adjacent pair of said modules to one another, each of said hems extending downwardly relative to said upper surface and providing transverse support for said panel, and each of said hems providing means for facilitating severance of said modules whereby at least one of said modules can be separated from the respective modular floor panel along such hem for forming panels of selected lengths, said panels being disposed in coplanar relationship with one another and with said side edges of adjacent panels adjacent to one another;

(b) a support beam extending subjacent each said pair of adjacent panel side edges; and

(c) a plurality of support posts for each of said beams, each of said posts straddling the respective beam and being in generally vertical alignment therewith.

2. A modular floor panel combination as in claim 1 wherein each such integral transverse hem is scored thereacross for readily separating at least one of said modules from said floor panel.

3. A modular floor panel combination as in claim 1 wherein said means at each of said hems for facilitating severance of said modules comprises a bight portion with a plurality of slits arranged in substantially linear spaced relationship with each other and extending the length of said integral transverse hem, and two side walls in substantially parallel relationship extending vertically subjacent to said modules and integral with the respective bight.

4. A modular floor panel combination as in claim 3 wherein each such transverse hem is inset from each respective side edge whereby the length of said hem is less than the width of the respective floor panel.

5. A modular floor panel combination as in claims 1, 2, 3 or 4 wherein each of said support beams comprises a vertical trough including two opposite sides and two ledges extending laterally from opposite sides of the trough whereby the side edges of two adjacent panels are received in said trough and a portion of each of said hems of each said panel engages the respective adjacent ledges of said support beams.

6. A modular floor panel combination as in claim 1 wherein each of said modules has an embossment integral with said module.

7. A modular floor panel combination as in claim 1 having first and second modular floor panels wherein each of said modular floor panels has a U-shaped hem at one end and a flange at the opposite end and wherein said flange of said first panel is inserted into said U-shaped hem of said second panel.

8. A modular floor panel combination as in claim 1 or 7 including first and second modular floor panels, a transverse clip having a trough therein, each of said panels having a flange at one end, and said flange of said first panel abutting said flange of said second panel and said flanges being inserted into said trough for joining said panels.

9. A modular floor combination as in claim 1 including at least one transverse clip having a trough wherein said transverse hem is inserted into said trough and an end of said transverse clip is held by said beam.

10. The modular floor panel combination as in claim 1, 2, 3, 4, 6, 7 or 9 wherein each of said support beams is a separate element from the respective panels and supports the respective side edges thereover.

11. The modular floor panel combination as in claim 10 wherein each of said support beams is an integral member and of a length to span a plurality of said modules of a panel.

14. The invention as in claim 1 or 12 wherein each of said modular floor panels has a U-shaped hem at one end and a flange at the other end for engaging with a U-shaped hem of another panel.

12. An elongated modular grain bin floor panel formed of an integral piece of bendable sheet metal and comprising opposite side edges, two opposite ends, a plurality of modules of said sheet metal arranged end-to-end in a series from one of said ends of said panel to the other and forming a substantially continuous upper surface of said panel from one of said ends to the other, a transverse hem of said sheet metal extending downwardly relative to said upper surface and integrally joining each adjacent pair of said modules and providing transverse support for said panels, and each of said hems providing means for facilitating severance of said modules, whereby at least one of said modules can be separated from said modular floor panel along one of said hems.

13. An elongated modular sheet metal bin floor panel as in claim 12 wherein said means at each of said hems for facilitating severance of said modules comprises a bight portion with a plurality of slits arranged in substantially linear spaced relationship with each other and extending along the length of the respective integral transverse hem, a two side walls extending from said bight and integral with the respective module.

15. In a grain storage bin comprising a plurality of contiguous elongated floor panels and means for supporting said elongated panels above a base, the improvement which comprises each of said elongated panels being formed of an integral piece of bendable sheet metal and including a plurality of modules disposed in end-to-end relation to one another and forming a substantially continuous upper surface extending the length of said panel, a transverse hem of said sheet metal joining each adjacent pair of said modules, each of said hems extending transversely of the respective panel and downwardly relative to said upper surface to provide transverse support for said panel and including means for facilitating severance of selected modules from said elongated panel and comprising a bight portion and two side walls extending from said bight and integral with the panel portion on the respective side of said hem whereby each of said elongated floor panels can be readily severed at any such hem.

16. The improvement as in claim 15 wherein each of said bight portions is found with a plurality of slits in substantially linear relationship with each other and extending along the length of the respective hem.

17. A method of forming a floor in a grain storage bin comprising providing elongated floor panels formed of bendable sheet metal, each having a substantially continuous upper surface and transverse hems extending transversely of the respective panel and downwardly relative to said upper surface to provide transverse support for said panel and each of said hems providing means for facilitating severance of said panels at modular spacings, and severing said panels into desired lengths by bending and breaking at selected hems.
