FR2471165A1 - COLUMN CONSTRUCTION FOR OVERHEAD STORAGE CONTAINER - Google Patents

Abstract

THE PRESENT INVENTION CONCERNS A CONSTRUCTION OF COLUMN FOR STORAGE RACK 11 OF A TYPE INCLUDING U-SHAPED SUPPORTS 19 WHICH SURROUND COLUMN 13 AND SUPPORT LOAD SUPPORT ARMS 14. THE CONSTRUCTION IS PARTICULARLY SUITABLE WITH HEAVY LOADS AND INCLUDES A PAIR OF LATERAL BODIES IN THE FORM OF A RELATIVELY THICK METAL CHANNEL AND A PAIR OF END BODIES WELDED TO THE FLASKS OF THE LATERAL BODIES, THE END BODIES CONSISTING OF RELATIVELY THICK METAL PLATES. THIS ALLOWS THE MOMENT OF INERTIA TO BE INCREASED WHILE REQUIRING ONLY A SMALL NUMBER OF PARTS AND WELDING CORDS.

Description

1.

  The present invention relates to storage racks

  cantilever type of the type used in indoor environments

  industrial and, more particularly, cantilevered storage racks which use columns and arms of rectangular section with U-shaped supports surrounding the columns, the arms being adjustable in height by the insertion of axes in openings in supports and columns. U.S. Patent No. 3,212. 648 in the names of Baker and others describes a cantilevered structure intended

to be used in industrial environments for sto-

  ckage of relatively heavy materials such as bars or

  tubes. The frame uses columns having a rectangular shape

gular in cross-section and arms with U-shaped supports which surround the columns. Axes extend in

  openings aligned in the supports and columns, so

  that the weight of the material acting on the arms tends to

compress and arch the columns.

It is sometimes necessary to have a

  higher load capacity for these frames. A per-

  putting to achieve this consists in increasing the thickness of the

  tal used in the manufacture of the column. In the patent of Baker and others, the rectangular column consists of two symmetrical sections having the general shape of a channel, 2. with flanges turned inside which are fixed together by welding. The camber of the channels is conventionally formed in the press. These presses have limited capacity and sometimes

are not capable of arching very thick metals-

sister. In addition, with the increase in nominal capacity, the total cost of the steel required to manufacture these columns is high. Thick metal design columns

conventional would require a larger width in the di-

  rection parallel to the core of the columns to take into account the 10 dies of the presses. The bending radii at the corners of these very thick parts should also be larger, which means that the openings for receiving the

axes should be further away from the soul of the colon

born. It has been suggested as a construction variant that four bars of rectangular section be inserted in the column immediately inside the cores and between the

flanges turned inwards. These reinforcement bars require

However, there are many welding operations, some

  nes of which are difficult to perform because of the man-

than accessibility.

An object of the present invention is to provide

  an improved column construction for sto racks

cantilever ckage of the type described above, which

  come especially for heavy loads and avoid the need to carry them with a greater width or

  using an excessive amount of metal.

  Another object of the present invention is to pre-

  see an improved column construction of this nature

re which can be manufactured using cam presses

brage of limited capacity.

  Another object of the present invention is to pre-

see a cantilever frame column construction having the above characteristics, which requires a minimum number of parts and welds, thereby reducing labor and manufacturing costs and times

of production.

In short, the present invention comprises, in combination

  naison with a type cantilevered storage rack

  comprising arms with U-shaped supports surrounding a co-

lonne rectangular and linked to it by transverse axes

  sant openings made in the column and the support,

  an improved column construction comprising two or-

  relatively small thickness metal channel ganes

  tite, each channel-shaped organ having a relative soul

wide and relatively shallow flanges, rows of openings in the cores adjacent to the flanges to receive the axes, and substantially more plates

  thicker than the channel-shaped organs covering the former

  inner flanges so as to form the souls of the colon-

  ne, the width of the plates being less than the distance between

the outer surfaces of the cores of the channel-shaped members, the plates being welded along their edges

opposite the flanges.

  The present invention will be well understood during

  the following description made in conjunction with the drawings below

seals in which: Figure 1 is a side elevation view of a cantilevered storage rack according to the present invention; Figure 2 is a sectional view of the column to represent its construction, taken along line 2-2 of Figure 1; and Figure 3 is a sectional view of an alternative column in which the flanges of the shaped bodies

  channel abut against the ends turned inwards.

  The cantilever frame is generally represented

  tee in ll and includes a plurality of parallel bases 12 dis-

  Aunts from each other on which vertical columns are mounted 13. The columns are tapered upwards and support cantilever arms, shown at 14, on their opposite sides. Each column has a rectangular section, having a pair of facing souls represented

  at 15 which are relatively narrow, and sides represent

  tees in 16 and 17 which are relatively wide. A plurality 4. of pairs of apertures 18 spaced apart from each other in the vertical direction is formed in the column 13 inside

souls 15.

  Each cantilever arm 14 has a U-shaped support, shown in 19, which is fixed at its inner end. The support is provided to surround the core 15 with

  column 13, the flanges 21 of the support covering the ribs

tees 16 and 17 of the column. Each support has a payment

re of aligned openings 22 which are provided to receive an axis 23, the axis also passing through the aligned openings 18

of the column so as to fix the arm there. The other characteristics

  specific aspects of construction with openings and

  axes are described in the Baker et al patent cited above

above.

  It will be noted that the charge exerted on does not

  which arm 14 will tend to arch the column 13 around its arching axis shown in dotted lines at 24 in the

Figure 2, this axis being that around which the moment of inertia

tie is measured. According to the present invention, column 13

  consists of a pair of side members in the shape of a

  nal, shown in 25 and 26, and a pair of organs or

end points shown at 27 and 28. Each side member

  ral 25 and 26 has a relatively wide core 29 and relatively short flanges 31 and 32. The shaped bodies

are made from a metal having a thick-

  relatively large sor, that is to say of material which is substantially thinner than the members 27 and 28. The

  angles 33 of members 25 and 26 have relatively small radii

  breasts which can be formed on a conventional press.

  Bodies 27 and 28, on the other hand, are manufactured

  from relatively thick metal and include plates

ques having a rectangular section shape. The width of these plates is somewhat less than the distance separating the outer surfaces of the cores 29. Weld beads 34 are used to fix the edges of the plates 27 and 28 to the flanges 31 and 32. These weld beads leave the

  external surfaces of the free plates, which allows the re-

design of supports 19.

  Note that only four pieces are needed to

make column 13 and only four weld beads

re are necessary for fixing the components. Parts 16 and 17 can be produced with presses

  arching of limited capacity. After assembly, the main part

  metal blade of the column will be at a significant distance from the axis 24, which will give a moment of inertia relatively

high for this part and will reinforce its mechanical resistance-

for a given metal weight. As the thickness of the pieces 16

  and 17 is relatively small, spokes 33 may be small.

  breasts and openings 18 be placed in their normal position relative to the souls of a column. The cords of

solder used for fixing parts are all easy-

  accessible and can therefore be placed with

minimal effort.

  If we compare the cost of manufacturing a co-

  lonne according to the present invention to that of a column of-

classic, but with thicker sheet metal parts,

  it has been found that the advantages offered by the present invention

  tion were more important for higher load capacities. The thickness of the plates 27 and 28 can, for example,

  vary between 6 mm and 38 mm, and when plates relative-

thick are used, the total cost is less than

  that of a thicker sheet metal column of classic design

  if that. The depth of the column, i.e. the distance separating the exterior surfaces of the two plates 27 and 28

  may obviously be variable, but will, in any case,

se, significantly larger than the width of the column

be the outer surfaces of the cores 29.

FIG. 3 represents a variant of the present

  the invention which uses lateral shaped bodies

  similar to those represented in the Baker patent and elsewhere

very, that is to say having ends turned inwards

  at the inner ends of the flanges. The column is gener-

actually shown in 101 and includes a pair of organs

  in the form of a channel generally represented at 102 and 103. Cha-

  6. that the channel-shaped member comprises a core 104 which is relatively wide and a pair of flanges 105. The flanges have ends turned inwards and the ends of the members 102 and 103 abut one against the other. Welding beads 107 are placed along the junction of these ends, these beads being flush with the exterior surfaces

souls 105 so as not to hinder the placement of the

external.

  The pair of outer plates 108 and 109 is fi

attached to the outer surfaces of the flanges 105. As before-

  ment, the width of these plates is somewhat less than

  the distance between the outer surfaces of the cores 104.

  The thickness of the plates 108 and 109 is substantially greater.

  re to that of the members 102 and 103. Weld beads 111 are formed along the lateral edges of the plates 108 and 109 so as to fix the plates to the flanges 105. The beads are formed so as not to interfere with the mounting of the support 112

column.

  The appreciation of some of the measurement values

  above must take into account that they come from

  result from the conversion of Anglo-Saxon units into metric units

ques.

The present invention is not limited to the examples

  ples of realization which have just been described, it is on the contrary susceptible of variants and modifications which

will appear to those skilled in the art.
