Definitions
- the present invention relates to beam constructions and more particularly relates to sheet metal beam constructions usable in connection with pallet racks or the like.
- Producing such beams by methods other than cold forming e.g. by extrusion can provide different sectional thicknesses in various portions of a beam, but the metal in such beams does not possess the strength per unit weight of cold formed sheet metal. Furthermore fabrication of these beams may be relatively costly in that special extrusion dies are required for each beam size.
- the beam disclosed in the Mosinski patent is relatively strong because of the fact that the upper flange of the beam is composed of the double thickness of sheet steel.
- the vertically extending sides of the beam are comprised of only a single thickness of material.
- the lower flange of this beam is formed of a double thickness of the material resulting in excessive weight and strength in that portion of the beam.
- the extra thickness in the lower flange results in excessive cost.
- the prior art has also attempted to increase the strength of multi-part tubular beam constructions by providing stiflening bends and lips.
- stiffening lips increase the strength of beams having relatively small sectional thicknesses.
- stiffening bends and lips have necessitated assembling the beam members by telescoping one beam member within the other and then attaching the members together. Such assembly methods are ineflicient.
- the present invention provides an improved beam. construction of the tubular or box type having a relatively heavy, concentration of metal in the compression flanges and relatively light concentration of metal in the tension portion of the beam. Thus, a beam having maximum strength for a given beam weight is provided.
- a beam assembly constructed in accordance with the invention includes stiflening bends and lips. These bends and lips are so arranged that the compression flanges are fully effective and efficient assembly of the beam parts is facilitated. Moreover the bends and lips tend to maintain the beam assembled and provide a relatively regular unbroken exterior appearance.
- Flanges of the beam members are nested together to form the load supporting flange construction and cooperate to provide a mechanical interlock between the member flanges such that only tack welds along the tension flanges rather than structural welds are used to maintain the members in an assembled condition. Further, because of the stifiened lips on the compression flanges, these flanges need not be welded together.
- a beam constructed in accordance with the invention is quickly and easily assembled by placing a flange of one member within a flange of the other beam member and rotating the beam members together.
- the member flanges are securely locked together and nested by rotating the members together.
- the assembly is constructed such that the two members will stay together without locking. To assure against non-uniform appearance, and against partial separation of the members due to bowing, they are tack welded along the tension or lower flange.
- clips are welded to ends of the beams. These clips are suflicient to maintain the beam in assembled form without the provision of tack welding.
- the interlocking constructions involve the use of stiffening bends and lips on the compression flanges, the load carrying capacity of the beam is increased. Even though the nested flanges of the beam member are locked together, localized overstressing of the material of the nested flanges is avoided because the interlocking structure does not restrain slight movements of one flange relative to the other under load.
- the lower flange of the beam construction is defined substantially entirely by one of the beam members and is therefore of minimum section thickness and weight.
- the location at which the beam members are welded together is preferably in the vicinity of the bottom flange at a location where a lip on one member overlies the bottom flange of the other member.
- the assembly of the beam is quickly and easily effected with minimum production costs.
- the exterior of the beam is regular and clean in appearance. That is, the exterior surface extends substantially unbroken about the beam and the beam is devoid of projections, ridges ect.
- a principal object of the present invention is the provision of a new and improved beam of the character referred to having a relatively large load supporting strength and light weight and which is simply and economically constructed.
- FIG. 1 is a perspective view of a pallet rack employing beams constructed in accordance with the invention
- FIG. 2 is a sectional view as seen from the plane indicated by 2-2 of FIG. 1;
- FIG. 3 is a cross-sectional view of components of the beam of FIG. 2 prior to assembly.
- FIGS. 4, 5 and 6 are cross-sectional views of the beam components at different conditions during assembly.
- FIG. 1 A pallet rack 10 is illustrated in FIG. 1.
- the pallet rack 10 includes vertical supports 11-14.
- the verticals 11, 12 are spaced rigidly apart by laterals 15 and the verticals 13, 14 are spaced apart by laterals 16.
- Load supporting beams B extend between the verticals 11, 13, and 12, 14, respectively.
- the beams B are disposed in pairs at vertically spaced locations on the supports with each pair of the beams B having load engaging surfaces lying in a common horizontal plane for the reception of pallets (not shown).
- the verticals 11-14 are defined by channel-like sheet metal members.
- the laterals 15, 16 are received between the flanges.
- the closed side, or web, of each vertical has a plurality of openings 20 at vertically spaced locations.
- the openings 20 provide supporting surfaces which are engaged by clips 21 attached to ends of the beams B.
- the clips 21 preferably include fingers which extend into the openings 20 so that the beams B are removably secured to the verticals. This construction permits the eleva- 4 tion of each pair of the beams B to be adjusted.
- the construction of the verticals 11-14, laterals 15, 16 and the clips 21 is a conventional welded assembly and may be the same as that disclosed in the noted patent to Mosinski.
- the beam construction B is illustrated in cross-section in FIG. 2.
- the beam B is a generally tubular member having a top flange construction F1, a bottom flange construction F2, and webs or side walls W1, W2.
- the web W1 lies in a generally vertically extending plane while the web W2 includes laterally spaced wall portions 25, 26 defining a horizontal shoulder or ledge 27 between them.
- a pallet or dunnage can be supported on the shoulders 27 of a pair of the beams B, or upon the top flange construction F1.
- the shoulder 27 may be omitted so that the beam B defines a substantially rectangular tube.
- the beam B is a two part assembly including the beam members 30, 31 (see FIG. 3).
- the beam member 30 includes the web W1, a top flange 32 at the vertically upper side of the web W1, and a web stiffening lip 33 disposed along the vertically lower side of the web W1.
- the top flange 32 includes a horizontally extending flange part 34 and generally vertically extending flange stiffening lip 36.
- a web portion 35 extends along the side of the flange part 34 opposite the stiffening lip 36 functioning as another stiffening lip to strengthen the flange part 34.
- the web portion 35 is offset from the vertical plane of the web W1 by an offset 38.
- the flange stiffening lip 36 is disposed at a relatively large acute angle with respect to the plane of the flange portion 34 and connected to it by a bend 40.
- the web lip 33 at the vertically lower side of the web W1 is bent out of the plane of the web W1 along a bend 45 and extends horizontally a relatively short distance along the lower flange construction F2.
- the beam member 31 includes the majority of the bottom flange F2, the web W2 and a top flange 50.
- the top flange 50 has a horizontally disposed flange portion 5.1 which is disposed at right angles to the web portion 25 and connected to it by a longitudinally extending bend 52.
- the opposite lateral side of the flange 51 defines a flange stiffening lip 53 which is bent at right angles to the top flange portion 51 and connected to it by a bend 54.
- the portion of the lower flange F2 defined by the beam member 31, includes a generally horizontally extending flange portion 60 connected to the wall portion 26 by a bend 61.
- the flange portion 60 includes an offset part 62 which extends horziontally parallel to the flange portion 60 and is spaced from the flange portion 60 by an offset 63.
- a longitudinally extending flange stiffening lip 64 is connected to the offset portion 62 by a longitudinally extending bend 65.
- the flanges 50, 32 of the beam members 31, 30 respectively are nested together so that when the beam B is assembled these flanges are tightly interlocked and from the beam flange F1.
- the interlocking relationship between the flanges is due to the fact that the external dimension D1 across the flange 32 from the flange lip 35 to the bend 40 is the same or slightly larger than the internal dimension D2 from the flange lip 53 to the wall 25.
- the bends 40, 52 of the beam members 31, 30 are tightly engaged at one side of the flange construction F1 and the flange lips 35, 53 which are engaged at the opposite side.
- the interlocking cooperation between the flanges additionally causes slight compression of the flange portion 34 assuring tight engagement with the portion 51.
- FIGS. 4-6 illustrate assembly of the beam B.
- the beam member 31 is oriented with the flange 50 disposed along the lower side of the member 31.
- the beam member 30 is cocked relative to the beam member 31 so that the planes of the webs W1, W2 define an acute angle.
- the flange 32 of the beam member 30 is then inserted into the flange 50 of the member 31 along the entire length of the beam members.
- edge 70 of the flange lip 53 engages the offset 38 and the bend 40 engages the wall 25.
- the beam member 30 is then rotated about the edge 70 toward the member 31.
- the bend 40 provides a bearing surface which moves along the wall 25.
- the flanges of the members snap over center during assembly because the compression of the flange 32 and tension in the flange 50 are greater when the beam members 30, 31 are in their FIG. condition than when these members are in their FIG. 6 condition.
- the nested flanges tend to resiliently maintain the beam members assembled as illustrated in FIG. 6 without any additional structure for completing the assembly.
- the edge 70 of the flange lip 53 is disposed closely adjacent the offset 38 on the member 30 with the flange lip 53 disposed in the plane of the web W1.
- the web lip 33 overlaps the offset portion 62 and the bend 65 bears against the bend 45.
- the web lip 33 lies in the plane of and forms a part of the flange F2.
- the web lip 33 and the offset 63 are secured together by a weld either in the form of tack welds or a fillet weld 72.
- the formation of the weld 72 constitutes the final step in the assembly of the beam B. Where the beam is to be used in a pallet rack, the weld 72 can be omitted.
- the clips 21 are welded to the ends of the beam in the usual fashion and these welds along with the mechanical interlock of the upper flanges of the beam members maintain the beam in its assembled form.
- a box beam construction comprising:
- a first beam member including a web and first and second spaced flange portions projecting from longitudinally extending edges of the web, said flange portions projecting in generally parallel relationship from the same face of the web;
- said first flange portion including a central part and a lip projecting from a longitudinal edge of the central part, the lip being spaced from the web and generally paralleling the web, said lip projecting from the first flange portion toward the second flange portion;
