  The conventional configuration as described above is effective when the horizontal width of the column material is narrow to the extent that it is difficult to bolt the ends of the horizontal connecting members on both the left and right sides of the column material directly to the column material. However, there is a problem that the cost is high due to the connection plate, which is a separate part, a fastening device such as a rivet for attaching the connection plate to the support material, and the connection plate attaching work.

  An object of the present invention is to provide a rack capable of solving the above-mentioned conventional problems, and when the means thereof is shown with reference numerals of embodiments described later, a partition vertical frame is shown. 4a to 4c are erected at appropriate intervals in the rack length direction, and the racks are formed by connecting the column members 8 of the vertical frames 4a to 4c for each partition by a horizontal cylindrical connecting material 11, the horizontal Among the end portions of the cylindrical connecting material 11, the adjacent end portions 16 of the two horizontal cylindrical connecting materials 11 that are arranged on both sides of the one supporting material 8 and are adjacent to each other in the rack length direction are the supporting material. 8 are formed in a flat shape that overlaps with each other on the outside, and the two flat end portions 16 that are overlapped with each other are attached to the column member 8 by one bolt 30 that penetrates the two flat end portions 16 that are overlapped with each other. The flat ends that overlap each other 6 has a configuration in which the two horizontal cylindrical connecting members 11 on both sides of the support column 8 are formed eccentrically on the opposite sides inward and outward with respect to the cross-sectional center of the horizontal cylindrical connecting member 11. Yes.

  In carrying out the present invention having the above-described configuration, specifically, as described in claim 2, the horizontal cylindrical connecting member 11 has a length corresponding to a plurality of sections partitioned by the partition vertical frames 4 and 4a to 4c. The column material 8 of the partitioning vertical frame 4 positioned between both ends of the horizontal cylindrical connecting member 11 and the mounting portion 20 in the middle in the length direction of the horizontal cylindrical connecting member 11 are connected to one bolt 30. It can be fixed with. In this case, as described in claim 3, the horizontal cylindrical connecting member 11 is formed of a round pipe, and the side surface of the intermediate mounting portion 20 that contacts the support member 8 is the support member of the flat end portion 16. 8 can be formed on a flat surface (flat one side surface 21) that is flush with a side surface (flat outer surface 18) that is in contact with 8. Further, as described in claim 4, the horizontal cylindrical connecting member 11 is formed of a square pipe, and the flat end portion 16 has a thickness approximately half of the width of the horizontal cylindrical connecting member 11. The side surfaces (flat outer surface 18, flat one side surface 21) that come into contact with the flat end 16 and the column member 8 of the intermediate mounting portion 20 may be formed flush with the side surface of the square pipe. it can.

  Further, as described in claim 5, the flat end 16 of the horizontal cylindrical connecting member 11 is horizontally aligned so that the vertical width thereof is substantially the same as the vertical width of the horizontal cylindrical connecting member 11. The plate members 16 a and 16 b on the upper and lower sides of the cylindrical connecting member 11 can be formed so as to be folded inside the flat end portion 16.

  Further, as described in claim 6, the horizontal cylindrical connecting member 11 connects the front supporting members 8 and the rear supporting members 9 of the vertical frames 4 and 4c for the compartments separately. When the horizontal brace material 12 is installed between the two horizontal cylindrical connecting members 11 on the front and rear sides of the horizontal cylindrical connecting member 11, the horizontal cylindrical connecting member 11 and the upper side thereof are arranged. The horizontal brace material 12 is fastened with a countersunk head bolt 33 and a nut 34 that pass through these from the bottom upward. The burring mounting hole 24 into which the countersunk head 33a of the countersunk head bolt 33 is fitted can be provided.

  Furthermore, as defined in claim 7, the bolts are disposed on the inner side of the outer vertical wall plate portion 25a to which the horizontal cylindrical connecting member 11 is attached to the support members 8, 9 of the partition vertical frames 4, 4a-4c. A nut 29 into which 30 and 32 are screwed can be fixed.

  According to the rack according to the present invention having the above-described configuration, the horizontal connecting member for connecting the column members of the partition vertical frame is not a flat bar but a cylindrical body such as a round pipe or a square pipe. It is possible to ensure the strength, but instead of using a separate connecting plate or the like to connect the support column and the ends of the horizontal cylindrical connecting members on both sides thereof, both horizontal cylindrical connections Since the flat ends of the material are stacked and fixed directly to the column material with a single bolt, the number of parts and man-hours required to join the horizontal cylindrical connecting material to the column material is greatly reduced, greatly increasing Cost reduction. In addition, as a support material, it is only necessary to have a width that allows a nut, which is a fastening partner of one bolt, to be placed inside, so a light load rack that can be assembled with a vertical frame for compartments using a support material with a very narrow width. Especially effective. Moreover, the horizontal tubular connecting member having the outer end portion among the end portions that are overlapped with each other on the outer side of the column member protrudes outside the rack with respect to the horizontal cylindrical connecting member having the inner end portion. It is possible to connect the strut members of the vertical frames for each partition in the same state as the state where one long horizontal cylindrical connecting member having the same rack length and overall length is used. Even when the rack according to the present invention is arranged on both sides of the traveling passage of the loading / unloading traveling crane to constitute an automatic warehouse, the horizontal cylindrical connecting member having the end portion which becomes the outside of the passage width between the racks on both sides There is no need to expand the horizontal width by two times, and the floor surface utilization efficiency does not decrease.

  In addition, according to the structure of Claim 2, compared with the case where the horizontal cylindrical connection material is divided | segmented for every division between the vertical frames for division, the processing cost of the edge part with respect to a horizontal cylindrical connection material It is possible to reduce the overall cost, and at the same time, it is possible to increase the connection strength between the vertical frames for the partition as a whole rack. In this case, according to the configuration described in claim 3, the horizontal tubular connecting member having the necessary bending strength can be configured to be lightweight and inexpensive using a round pipe, and the horizontal tubular connecting member Similarly to the end portion, the intermediate mounting portion between both ends can be bolted stably to the support material in a surface contact state. Moreover, according to the structure of Claim 4, a special process is unnecessary for the intermediate attachment part between the both ends of a horizontal cylindrical connection material, and implementation becomes easy.

  Moreover, according to the structure of Claim 5 or 6, the height of the load storage space adjacent to the lower side of a horizontal cylindrical connection material among the load storage spaces formed between the vertical frames for division is said horizontal. The space between the vertical frames for partitioning (load storage) is not reduced by the expansion of the vertical width of the end of the cylindrical connecting material or the head of the bolt that joins the horizontal cylindrical connecting material and the horizontal brace material above it. Even when the width of the space is narrowed sufficiently, the lifting load when loading and unloading the rack using a running fork and forklift that can be moved up and down of the traveling crane for loading and unloading is connected in a horizontal cylinder. It is not restricted by the expansion of the vertical width of the end portion of the material or the bolt head that joins the horizontal tubular connecting material and the horizontal brace material.

  Furthermore, according to the structure of Claim 7, compared with the case where a horizontal cylindrical connection material must be bolted, hold | maintaining a nut inside the support | pillar material of the division | segmentation vertical frame, it is horizontal with respect to a support | pillar material. The bolting operation of the cylindrical connecting material can be performed easily and efficiently.

The vertical frames 4a, 4b and the vertical frames 4b, 4c for the compartments are connected to each other on the back side not facing the traveling passage 3 and are connected to the vertical plane braces 6a, 6b. 4c is provided with a load support 7 that forms a load storage space in a plurality of upper and lower stages between adjacent vertical frames 4 and 4a to 4c. Each of the horizontal connection frames 5a and 5b is disposed in the vicinity of the upper end of the load storage space formed on the upper side of the load support 7 so as not to obstruct the loading and unloading of the load. Of course, the level of the load storage space at which the horizontal connection frames 5a and 5b are disposed in the vicinity of the upper end may be higher than the height of the load storage space at other levels.

  Each partition vertical frame 4, 4 a to 4 c is a lattice comprising a front side (traveling passage 3 side) support material 8, a rear support material 9, and an oblique connection material 10 that connects and integrates both front and rear support materials 8, 9. The load supporting device 7 of each stage is attached to the side surfaces of both the front and rear support members 8 and 9 in a cantilever manner at both front and rear ends.

  The horizontal connecting frames 5a and 5b at each stage are two horizontal cylindrical connecting members for connecting the front and rear support members 8 and the rear support members 9 of the partition vertical frames 4 and 4a to 4c. 11 and a plurality of horizontal brace members 12 installed obliquely between the front and rear horizontal cylindrical connecting members 11 divided between adjacent partition vertical frames 4 and 4a to 4c.

  The two rows of racks 1A and 1B are installed on the floor surface at the lower ends of both front and rear support members 8 and 9 of the vertical frames 4 and 4c for each partition, but the upper ends are shown in FIGS. As shown in FIG. 4, the partition vertical frames 4, 4a to 4c positioned at appropriate intervals in the length direction of both racks 1A and 1B, specifically, the partition vertical frames 4a at both ends of each of the two groups G1 and G2 4c for the front struts 8c and the front struts 8 of the partition vertical frame 4 located at the center in the rack length direction of each of the groups G1 and G2 cross over the traveling path 3. An upper guide rail 14 that is connected by a beam member 13a and a horizontal brace member 13b installed between the connecting beam members 13a and that guides the upper end side of the loading / unloading traveling crane 2 is provided on the lower side of each connecting beam member 13a.

All the horizontal cylindrical connecting members 11 constituting the horizontal connecting frames 5 a and 5 b have the same structure configured by using round pipes. As shown in FIGS. 5 to 7, both end portions 16 have one imaginary plane passing through the center of the round pipe (the center of the cross section of the horizontal cylindrical connecting member 11), a flat inner surface 17 that is flush with the imaginary plane, and the flat portions. In addition to being formed into a flat shape having a flat outer surface 18 parallel to the inner side surface 17, one mounting hole 19 penetrating between both inner and outer side surfaces is formed in each flat end portion 16. Further, the thickness of the flat end portions 16, that is, the distance between the flat inner surface 17 and the flat outer surface 18 is the radius of the round pipe (half the thickness of the horizontal cylindrical connecting member 11 in the same direction). The flat outer surface 18 is also formed so as to enter the inner side of the peripheral surface of the round pipe (the side surface of the horizontal cylindrical connecting member 11). Furthermore, when the end portion of the round pipe is simply pressed into a flat shape to form the flat end portion 16, the width (height) of the flat end portion 16 is equal to the diameter of the round pipe (this horizontal cylindrical connecting member 11). 5B, 6A, and 7A, the width of the flat end portion 16 is the diameter of the round pipe (the height of the horizontal cylindrical connecting member 11). The plate members 16 a and 16 b on both sides of the flat end portion 16 are folded and formed inside the flat end portion 16 so as to be substantially equal to the flat end portion 16.

  The front and rear horizontal cylindrical connecting members 11 are also coupled to a partition vertical frame 4 (specifically, three intermediate partition vertical frames 4) located between the groups G1 and G2. As shown in FIGS. 5A and 6C, each mounting portion with the partition vertical frame 4, that is, each intermediate mounting portion 20 between both ends of the horizontal cylindrical connecting member 11, is a flat outer surface of the flat end portion 16. 18 and a flat one side surface 21 that is flush with the flat one side surface 21 and a flat other side surface 22 that is parallel to the flat one side surface 21 and symmetrical with respect to the center of the cross section of the horizontal tubular connecting member 11 (the axis of the round pipe), The round pipe is formed by pressurizing in the same direction as when the flat end 16 is formed, and the mounting holes 23 are formed so as to penetrate the flat side surfaces 21 and 22 concentrically. Of course, also in this case, if the intermediate mounting portion 20 is formed by simply press-molding the intermediate portion of the horizontal cylindrical connecting member 11 in a flat shape, the width (height) of the intermediate mounting portion 20 is the horizontal. Since the width of the cylindrical connecting member 11 is slightly larger than the width in the same direction (diameter of the round pipe), as shown in FIGS. 5B and 6C, the width (height) of the intermediate mounting portion 20 is increased as necessary. ) Restricts the swelling of both side surfaces in the width (height) direction when the intermediate mounting portion 20 is formed so that the horizontal cylindrical connecting member 11 is substantially equal to the width in the same direction (diameter of the round pipe). It is desirable to mold.

  Further, the horizontal cylindrical connecting member 11 has a mounting hole penetrating in a direction close to the inside of the flat end portion 16 and on both sides of each intermediate mounting portion 20 in a direction orthogonal to the mounting holes 19 and 23. 24 is provided. As shown in FIGS. 6B and 7A, each of the mounting holes 24 has a short peripheral wall 24a projecting inward of the horizontal cylindrical connecting member 11 and is open in a trumpet shape with respect to the peripheral surface of the horizontal cylindrical connecting member 11. It is a burring hole.

  As shown in FIG. 8, the front and rear support members 8 and 9 of the partitioning vertical frames 4 and 4a to 4c that are connected to each other by the front and rear horizontal cylindrical connecting members 11 are rectangular tube-shaped cross sections. It consists of a main body 25 and a pair of protruding plate portions 26 that are bent outwardly from both side edges of the rectangular tube-shaped main body 25, and the pair of protruding plate portions 26 are divided vertical frames 4, 4a to 4a. It is located inside 4c, and is fixed in a state in which the end of the oblique connecting member 10 is inserted therebetween. Thus, the horizontal cylindrical connecting members 11 of the horizontal connecting frames 5a and 5b at the respective stages are provided on the outer vertical wall plate portion 25a of the rectangular cylindrical main body 25 facing the outside of the partitioning vertical frames 4 and 4a to 4c. A through screw hole 27a for bolting is provided, and at least the rear strut member 9 is adjacent to the top and bottom of the through screw hole 27a, and the through screw hole for bolting the vertical surface braces 6a, 6b. 28a and 28b are provided. Each of the through screw holes 27a to 28b is configured by an insert nut 29 that is disposed inside the rectangular tubular body 25 and is caulked and fixed to the outer vertical wall plate portion 25a. As the insert nut 29, a so-called pop (POP) nut that can slightly suppress the amount of outward protrusion from the outer vertical wall plate portion 25a can be used.

  The procedure for assembling the racks 1A and 1B by connecting the partition vertical frames 4 and 4a to 4c to each other will be described. Each partition vertical frame 4 assembled in advance by the front and rear support members 8 and 9 and the oblique connection member 10 is described. 4a to 4c at predetermined positions on the floor surface, the partition vertical frames 4 and 4a to 4c are parallel to each other, and the outer side surface of the front column member 8 (the surface of the outer vertical wall plate portion 25a) and the rear column member 9 Are arranged perpendicularly to the two front and rear virtual vertical planes parallel to each other and the vertical frames 4a for partitioning at both ends of the group G1. Horizontal connection frames 5a and 5b are installed in a plurality of upper and lower stages at the same level between 4b and between partition vertical frames 4b and 4c at both ends of group G2.

  That is, a horizontal cylindrical shape is formed between the front strut members 8 and the rear strut members 9 of the partition vertical frames 4a and 4b, and between the front strut members 8 and the rear strut members 9 of the partition vertical frames 4b and 4c. The connecting members 11 are installed, but the two horizontal cylindrical connecting members 11 arranged at the same level on both sides of the partitioning vertical frame 4b are connected to the flat end portions 16 adjacent to each other, as shown in FIGS. 9B and 10B. As shown in FIG. 2, the flat inner surfaces 17 are overlapped with each other so that they are in contact with each other, and a single bolt 30 is inserted from the outside into the mounting holes 19 of the two flat end portions 16 that overlap each other. The vertical frame 4b is screwed and fastened to the through screw hole 27a (insert nut 29) on the front column material 8 and the rear column material 9 side.

  As shown in FIGS. 9A and 9C and FIGS. 10A and 10C, the flat end 16 on the free end side of each horizontal tubular connecting member 11 is also independent of the vertical frames 4a and 4c for partitioning at both ends of the groups G1 and G2, respectively. Although fixed to the front and rear support members 8 and 9 with one bolt 30, as shown in FIGS. 9A and 10A, the outer surfaces of the front and rear support members 8 and 9 (the surface of the outer vertical wall plate portion 26a). The flat end 16 in the direction in which the outer flat surface 18 directly abuts is fixed to the front and rear support members 8 and 9 by using one bolt 30 and the through screw hole 27a (insert nut 29) as it is. As shown in FIGS. 9C and 10C, the flat end portion 16 in which the flat inner side surface 17 faces the outer surface of the front and rear support members 8, 9 (the surface of the outer vertical wall plate portion 26a), The flat inner surface 17 of the flat end portion 16 and both front and rear support members 8 9 with a spacer 31 having a thickness substantially the same as the thickness of the flat end portion 16, and using one bolt 30 and a through screw hole 27 a (insert nut 29). It is desirable to fix to both front and rear support members 8,9. As the spacer 31 in this case, as shown in FIGS. 9C and 10C, the spacer 31 has substantially the same width as the widths of the front and rear support members 8 and 9, and at least one of the upper and lower sides of the flat end portion 16. It is preferable to use one provided with a detent projection 31a that abuts against.

  As described above, the horizontal cylindrical connecting member 11 is divided between the front strut members 8 and the rear strut members 9 of the partition vertical frames 4a and 4b, and between the front strut members 8 and the rear struts of the partition vertical frames 4b and 4c. When installed between the members 9, both the front and rear columns of the partition vertical frame 4 in which the flat one side surface 21 or the flat other side surface 22 of the intermediate mounting portion 20 of each horizontal tubular connecting member 11 is located in the middle of each group G1, G2. Since the material 8 and 9 are brought into contact with each other in a surface contact state, as shown in FIG. 11, one bolt 32 is inserted into the mounting hole 23 of each of the intermediate mounting portions 20 and the vertical frame 4 for each partition 4 is inserted. The through screw holes 27a (insert nuts 29) in the front and rear support members 8, 9 are screwed and fastened. Thus, all the partition vertical frames 4, 4a to 4c of each group G1, G2 are connected by the horizontal cylindrical connecting member 11 at a predetermined level, but at this time, they are on both sides of the partition vertical frame 4b. The two horizontal cylindrical connecting members 11 connected at the same level in the rack length direction are concentric at the cross-sectional center (axial center of the round pipe), and the heel is also one long horizontal cylindrical connecting member. Is the same as the state of being installed between the partition vertical frames 4a and 4c at both ends of the rack.

  Next, a horizontal brace material 12 is installed between the front and rear horizontal cylindrical connecting members 11 located in the same group G1, G2. That is, the horizontal brace material 12 is diagonally arranged between the vertical frames 4, 4 a to 4 c for each section, and as shown in FIGS. 9 to 11, the ends of the horizontal brace materials 12 are connected to the front and rear horizontal cylindrical connecting members. 11 is stacked on the mounting hole 24 at a position adjacent to the vertical frames 4, 4 a to 4 c for each partition, and the countersunk head bolts 33 are placed on the mounting hole 24 and the horizontal brace material 12 from the lower side of the horizontal cylindrical connecting member 11. And the nut 34 is screwed and fastened on the upper side of the horizontal brace material 12. At this time, as shown in FIG. 12, the countersunk head 33a of the countersunk bolt 33 is fitted into the trumpet opening of the mounting hole 24 formed by burring, so that it protrudes below the horizontal cylindrical connecting member 11. The projecting amount of the bolt head to be made can be zero or small.

  Through the above operation, all the partition vertical frames 4 and 4a to 4c are connected and integrated by the plurality of horizontal connection frames 5a and 5b. After this, for each group G1, G2, the rear support members 9 of the partition vertical frames 4a, 4b and the rear support members 9 of the partition vertical frames 4b, 4c are connected to the vertical support braces 6a in a plurality of upper and lower stages. , 6b, the assembly of each rack 1A, 1B is completed. As shown in FIG. 10, the vertical surface braces 6 a and 6 b are formed by using through screw holes 28 a and 28 b (insert nuts 29) provided in the rear strut members 9 of the partitioning vertical frames 4 a to 4 c. The end plate 36a of the brace material 36 that is adjustable in length and includes, for example, turn buckle type tension means 35 that constitutes the surface braces 6a and 6b can be attached with one bolt 37. The two brace end plates 36a of the two vertical surface braces 6a and 6b arranged symmetrically with respect to the partitioning vertical frame 4b on both sides of the partitioning vertical frame 4b are overlapped with each other with one bolt 37 and one. The two through screw holes 28a or 28b (insert nut 29) can be used for attachment.

  In the above embodiment, as shown in FIG. 5A, the flat end portions 16 at both ends of the horizontal cylindrical connecting members 11 constituting the horizontal connecting frames 5a and 5b are eccentric to the same side. As shown in FIG. 13A, the flat inner side surfaces 17 of the flat end portions 16 at both ends may be eccentric to each other in opposite directions so as to be opposite to each other. Further, in the above embodiment, the thickness of the flat end portion 16 is made smaller than half of the thickness in the same direction of the horizontal cylindrical connecting member 11 (the radius of the round pipe), and the flat outer surface 18 is also connected to this horizontal cylinder. 13B, the flat end portion 16 has a thickness in the same direction as that of the horizontal cylindrical connecting member 11, as shown in FIG. 13B. It is also possible to configure the flat outer surface 18 to be flush with the same side surface (circumferential surface of the round pipe) of the horizontal cylindrical connecting member 11 so as to be equal to half the radius (the radius of the round pipe). It is. In this case, the intermediate mounting portion 20 of the horizontal tubular connecting member 11 presses the round pipe in a direction orthogonal to the pressurizing direction at the time of forming the flat end portion 16, while the flat one side surface 21 and the flat other side surface. 22 should be located at a distance approximately equal to the diameter of the round pipe. Of course, the intermediate mounting portion 20 may be configured using the peripheral surface of the round pipe as it is.

  As shown in FIG. 14, the horizontal cylindrical connecting member 11 can be configured using a square pipe. In this case, the flat end portions 16 at both ends are half the thickness of the square pipe in the same direction, so that one side surface of the horizontal cylindrical connecting member 11 and the flat outer surface 18 are flush with each other. The flat side surface 21 and the flat other side surface 22 of the intermediate mounting portion 20 can be configured so that both flat side surfaces of the square pipe can be used as they are.

  Further, among the horizontal cylindrical connecting members 11 arranged concentrically at the same level, the horizontal cylindrical connecting members 11 positioned at both ends (in the above embodiment, the horizontal cylindrical connecting members arranged concentrically at the same level). The flat end 16 of the above configuration is not formed at the free end of the horizontal cylindrical connecting member 11 because the number 11 is two, and the same structure as the intermediate mounting portion 20 is used. You can also. In this case, when using the horizontal tubular connecting material 11 using the square pipe shown in FIG. 14 or when the intermediate mounting portion 20 is left as it is with the round tubular connecting material 11 using the round pipe. The free end portion of the horizontal cylindrical connecting member 11 does not require special processing. Furthermore, the horizontal cylindrical connecting member 11 is independent for each of the adjacent partition vertical frames, and may not have the intermediate mounting portion 20.

  Further, the horizontal connecting frames 5a and 5b are constituted by the two front and rear horizontal cylindrical connecting members 11 and the horizontal brace member 12 laid between them. It can also be set as the structure connected, and even when employ | adopting the above horizontal connection frames 5a and 5b, the horizontal brace material 12 can also be arrange | positioned only at the both ends of the said horizontal connection frames 5a and 5b. Of course, the vertical surface braces 6a and 6b are not essential, and may be arranged in an appropriate area as necessary.
