Abstract

In a storage rack, in which each of two columns has an outer wall facing outwardly and a side wall facing the side wall of the other column, a steel beam including two flange sections and an intermediate section extends between and is supported by the columns. Being fastened to an associated column, each flange section has a side plate adjacent to the side wall of the associated column and an outer flange adjacent to the outer wall of the associated column. Extending horizontally between the flange sections, the intermediate section is welded at each of its opposite ends to the side flange of an associated one of the flange sections. Being rolled from a steel sheet and defining a downwardly opening channel profile, the intermediate section has an outer wall, an inner wall joined unitarily to the outer wall so as to define an upper edge of the intermediate section, and a lower flange extending inwardly from a lower portion of the inner wall and having an upturned edge. As supported by and on the upturned edge of the lower flange of the intermediate section, a deck is confined against outward movement by the inner wall of the intermediate section and against side-to-side movement by the side plates of the flange sections.

Claims

1. A storage rack comprising

(a) two columns, each said column having an outer wall facing outwardly and a side wall facing the side wall of the other column, and

(b) a steel beam extending between and supported by the columns, the beam including two flange sections and an intermediate section, each flange section being fastened to an associated one of the columns, each flange section having a side plate adjacent to the side wall of the associated one of the columns and an outer flange adjacent to the outer wall of the associated one of the columns, the intermediate section extending horizontally between the flange sections, the intermediate section having two opposite ends and being welded at each of the opposite ends to the side flange of an associated one of the flange sections, the intermediate section being rolled from a steel sheet and defining a downwardly opening channel profile, the intermediate section having an outer wall, an inner wall being generally vertical and being joined unitarily to the outer wall so as to define an upper edge of the downwardly opening channel profile, and a lower flange extending inwardly from a lower portion of the inner wall, the lower flange having an upturned edge spaced below the upper edge of the intermediate section,

wherein the upturned edge provides means for supporting a deck on the upturned edge, between the side plates and behind the inner wall, wherein the inner wall provides means for confining such a supported deck against outward movement, and wherein the side plates provide means for confining such a supported deck against side-to-side movement.

2. The storage rack of claim 1 wherein the outer wall of the intermediate section is inclined so as to extend downwardly and outwardly and so as to define an expansive surface facing upwardly and outwardly, the expansive surface being adapted to receive indicia via labelling or stencilling.

3. The storage rack of claim 2 wherein the outer wall of the intermediate section has a lower flange extending inwardly from the inclined portion.

4. The storage rack of claim 1 wherein the outer wall of the intermediate section is inclined so as to extend downwardly and inwardly and so as to define an expansive surface facing downwardly and outwardly, the expansive surface being adapted to receive indicia via labelling or stencilling.

5. A storage rack comprising

(a) two columns, each said column having an outer wall facing outwardly and a side wall facing the side wall of the other column,

(b) a steel beam extending between and supported by the columns, the beam including two flange sections and an intermediate section, each flange section being fastened to an associated one of the columns, each flange section having a side plate adjacent to the side wall of the associated one of the columns and an outer flange adjacent to the outer wall of the associated one of the columns, the intermediate section extending horizontally between the flange sections, the intermediate section having two opposite ends and being welded at each of the opposite ends to the side flange of an associated one of the flange sections, the intermediate section being rolled from a steel sheet and defining a downwardly opening channel profile, the intermediate section having an outer wall, an inner wall being generally vertical and being joined unitarily to the outer wall so as to define an upper edge of the downwardly opening channel profile, and a lower flange extending inwardly from a lower portion of the inner wall, the lower flange having an upturned edge spaced below the upper edge of the intermediate section, and

(c) a deck having an upper surface and a lower surface, the deck being supported at the lower surface by and on the upturned edge of the lower flange of the intermediate section, the upper surface being spaced below the upper edge of the intermediate section, the deck being confined by the inner wall of the intermediate section, so as to restrict outward movement of the deck, and by the side plates of the flange sections, so as to restrict side-to-side movement of the deck.

6. The storage rack of claim 5 wherein the outer wall of the intermediate section is inclined so as to extend downwardly and outwardly and so as to define an expansive surface facing upwardly and outwardly, the expansive surface being adapted to receive indicia via labelling or stencilling.

7. The storage rack of claim 6 wherein the outer wall of the intermediate section has a lower flange extending inwardly from the inclined portion.

8. The storage rack of claim 5 wherein the outer wall of the intermediate section is inclined so as to extend downwardly and inwardly and so as to define an expansive surface facing downwardly and outwardly, the expansive surface being adapted to receive indicia via labelling or stencilling.
