JP 2005-263403 A

  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, not only must both ends of the pipe material divided into sections by the vertical frame for each section be flattened, but also a number of bolts and their bolts for each column material of the vertical frame for each section. There was a problem that the cost was high due to the necessity of mounting man-hours.

  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. 2, 2a to 2c are erected at appropriate intervals in the rack length direction, and the rack members 6 and 7 of the vertical frames 2 and 2c for each partition are connected to each other by a horizontal connecting member 9. The horizontal connecting member 9 is composed of a flat bar having a length corresponding to a plurality of sections partitioned by the partitioning vertical frames 2 and 2a to 2c. 27a, mounting seats 18 and 26 provided with mounting holes 20 and 28 in the vertical direction are attached by a single mounting seat mounting bolt 19 and 29 in the front-rear and horizontal directions. An end 11 of the adjacent horizontal connecting member 9, 2 and the intermediate portion 13 are mounted by the mounting holes 20 and 28 and the horizontal connecting material mounting bolts 23 in the vertical direction in a state where the flat bar plate surface is in contact with the horizontal upper surfaces 21a and 27a of the mounting seats 18 and 26. The ends 11 and 12 of the horizontal connecting members 9 on both the left and right sides adjacent to the support members 6 and 7 are attached to one mounting seat by one horizontal connecting member mounting bolt 23 in a state where they are vertically stacked. 18 and 26 are attached.

  In carrying out the present invention having the above-described configuration, specifically, as described in claim 2, the mounting seat 18 includes the mounting seat mounting bolt 19 provided with the horizontal upper surface 21 a and the mounting hole 20. The head can be integrated. In this case, as described in claim 3, the mounting hole 20 of the mounting seat 18 can be formed by a screw hole into which the horizontal connecting material mounting bolt 23 can be screwed.

  According to a fourth aspect of the present invention, the mounting seat 26 includes a horizontal plate portion 27 having the horizontal upper surface 27a and a mounting hole 28, and the horizontal mounting portion 26 is bent from the horizontal plate portion 27 so as to be connected to the mounting seat. It is also possible to comprise a vertical plate portion 31 provided with a through hole 30 in the front-rear horizontal direction through which the mounting bolt 29 is inserted. In this case, as described in claim 5, the vertical plate portion 31 of the mounting seat 26 is provided with a bent side portion 31 a that engages with the side portions of the support columns 6 and 7 and prevents rotation. I can keep it.

  Furthermore, even when the structure of claim 2 or claim 5 is adopted as the mounting seat, the mounting seat mounting bolts 19 and 29 include the mounting seats 18 and 26 and the column material, as described in claim 6. The elastic seat plate 22 sandwiched between the surfaces 6 and 7 can be loosely fitted.

  According to the rack according to the present invention having the above-described configuration, the horizontal connecting member for connecting the supporting column members of the vertical frames for each partition is a flat bar having a number much smaller than the number of partitions by the vertical frame for the partition, and the end portion. A flat bar that does not require any special shape change processing can be used just by machining a hole through which one horizontal connecting material mounting bolt is inserted at the mounting location adjacent to the intermediate strut material. The mounting seats that are attached to the support members of the vertical frame for each partition are attached to one horizontal connection member, including the place where two horizontal connection members on both sides are attached to one support member. Because it can be attached with bolts, a large cost reduction can be achieved. In addition, since the flat bar that becomes the horizontal connecting member is oriented horizontally in the mounted state, the horizontal connecting frame that connects the adjacent vertical frames for the partition is connected to the front and rear horizontal connecting members and the two horizontal connecting members. When the lattice structure is configured with the connecting horizontal brace material, the horizontal connecting material and the horizontal connecting material are stably and firmly coupled with the bolts in the vertical direction as compared with the case where the horizontal connecting material is a round pipe material. be able to. Furthermore, compared with the case where the horizontal connecting material is a round pipe material, the height of the load storage space is lower due to the presence of the horizontal connecting material at the place where the horizontal connecting material is installed at the upper end of the load storage space. It is possible to reduce the height of the rack, and it is possible to suppress the entire rack from being raised by installing the horizontal connecting member.

  In addition, according to the structure of Claim 2, since the mounting seat attached to the support | pillar material of the division | segmentation vertical frame is integrally formed with the bolt for mounting seat mounting, the number of parts decreases and mounting work of a mounting seat is carried out. Will also be easier. In this case, according to the structure of Claim 3, compared with the case where a nut is used together, the number of parts becomes smaller and the mounting work of a mounting seat becomes still easier. And since the screw hole of an up-down direction is processed into the bolt head which has sufficient up-down direction thickness, a problem does not arise in the attachment strength of a horizontal connection material.

  Moreover, according to the structure of Claim 4, since the mounting seat which can be easily and easily comprised by bending a board | plate material can be attached to the support | pillar material of the division | segmentation vertical frame with a ready-made bolt, it is comparatively easy and The present invention can be implemented at low cost. In this case, according to the configuration of the fifth aspect, it is easy to place the surface to which the horizontal connecting material is attached in a direction that is surely the horizontal upper surface, even though the mounting seat is attached with one mounting seat mounting bolt. Can be attached to.

  Of course, even in the case of adopting the configuration according to claim 6, the mounting by the reaction force due to the elastic seat plate being sandwiched between the mounting seat and the column material surface and being compressed by fastening the mounting seat mounting bolt. Since a large rotational resistance around the bolt acts on the mounting seat just before the fastening of the seat mounting bolt, the surface to which the horizontal coupling material is mounted can be secured even though the mounting seat is mounted with a single mounting seat mounting bolt. It can be easily attached in a state where it is positioned in the direction of the horizontal upper surface.

  A specific embodiment of the present invention will be described below with reference to the accompanying drawings. As shown in FIG. 1, a rack 1 shown in this embodiment includes a large number of vertical frames 2 and 2a to 2c for partitions, The vertical frames 2 and 2a to 2c are composed of a plurality of upper and lower horizontal connection frames 3a and 3b, which are divided into a plurality of groups, in the illustrated example, divided into two groups G1 and G2 every four sections. 2a-2c is provided with a load support 4 that forms a load storage space in a plurality of upper and lower stages between the adjacent partition vertical frames 2, 2a-2c. Each of the horizontal connection frames 3a and 3b is disposed in the vicinity of the upper end of the load storage space formed on the upper side of the load support 4 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 3a and 3b are arranged near the upper end may be higher than the height of the load storage space at other levels. In addition, as indicated by phantom lines in FIGS. 1 to 3, the partition vertical frames located at appropriate intervals, in the illustrated example, the partition vertical frames 2a and 2b at both ends of the two groups G1 and G2 and the partition The vertical frame braces 5 that connect the vertical frames 2b and 2c on the back side where the load is not put in and out can be provided to increase the strength of the entire rack.

  As shown in FIG. 3, each of the partition vertical frames 2, 2 a to 4 c is diagonally connected and integrated with the front side (unloading side) support material 6, the rear support material 7, and the front and rear support materials 6, 7. The load support 4 of each stage is attached to the side surfaces of both the front and rear support members 6 and 7 in a cantilever manner.

  As shown in FIG. 2, the horizontal connection frames 3a and 3b at the respective stages are connected to the front and rear strut members 6 and the rear strut members 7 of the vertical frames 2 and 2c for the respective sections. It consists of a plurality of horizontal connecting members 9 and a plurality of horizontal brace members 10 that are diagonally installed between the front and rear horizontal connecting members 9 divided between adjacent vertical frames 2 and 2a to 2c.

  As shown in FIGS. 4 to 7, the horizontal connecting member 9 is formed of a flat bar, and the length thereof is substantially the same as the horizontal length (the length of four sections) for each group G1, G2. The both ends attaching portions 11 and 12 adjacent to the support members 6 and 7 of the partition vertical frames 2a to 2c at both ends of the groups G1 and G2 and the support members 6 of the partition vertical frame 2 between the groups G1 and G2 1 is provided with an attachment hole 14 in a state of penetrating in the thickness direction of the flat bar, in the intermediate attachment portion 13 adjacent to 7 (having three intermediate attachment portions 13 in the configuration of FIG. 1). . Further, the horizontal connecting member 9 has a lower opening facing the mounting holes 14 at positions equidistant to both sides in the lengthwise direction of the horizontal connecting member 9 (one side for both end mounting portions 11 and 12). A brace material mounting hole 15 is provided.

  On the other hand, a through screw hole 16 is provided at a location adjacent to the horizontal connecting member 9 of the support members 6 and 7 in each of the partition vertical frames 2 and 2a to 2c. Each of these through screw holes 16 is configured by an insert nut 17 that is disposed inside the support members 6 and 7 and is caulked and fixed to the outer vertical wall plate portion of the support members 6 and 7. As the insert nut 17, a so-called pop (POP) nut that can slightly suppress the protruding amount from the surface of the support members 6 and 7 to the outside can be used. A mounting seat 18 is attached using this through screw hole 16. The mounting seat 18 is configured integrally with the bolt 19 by a prismatic head portion of a bolt 19 having a screw shaft portion 19a that can be screwed and fastened to the through screw hole 16, and the shaft center of the screw shaft portion 19a. And a through screw hole 20 penetrating in a direction orthogonal to the direction. Further, both ends of the through screw hole 20 are open at right angles to a pair of flat side surfaces 21a and 21b which are parallel to each other among the four side surfaces around the mounting seat 18 (the prismatic bolt head).

  Each mounting seat 18 has a bolt screw shaft portion 19a penetrating the column members 6 and 7 through the bolt screw shaft portion 19a in a state where an elastic seat plate 22 formed of rubber or other synthetic resin is loosely fitted to the bolt screw shaft portion 19a. The elastic seat plate 22 is attached between the surface of the column members 6 and 7 and the side surface of the mounting seat 18 on the bolt screw shaft portion 19a side by screwing and fastening to the screw hole 16. At the final stage of screwing and fastening where the rotational resistance is increased by being pinched and compressed, the through screw hole 20 is oriented in the vertical vertical direction, that is, a pair of flat side surfaces 21a and 21b where the through screw hole 20 opens. The mounting posture of the mounting seat 18 is determined so that one of the mounting surfaces becomes a horizontal upper surface that supports the horizontal connecting member 9.

  As described above, if the mounting seats 18 are respectively mounted in the predetermined positions at the mounting positions of the horizontal connecting members 9 of the column members 6 and 7 of the vertical frames 2 and 2a to 2c for each partition, the both ends of the horizontal connecting members 9 are attached. The parts 11 and 12 and the intermediate mounting part 13 are placed on the horizontal upper surface (flat side surface 21a in the illustrated example) of the mounting seat 18 corresponding to each of these mounting parts, and are placed above the mounting holes 14 of the mounting parts 11-13. The horizontal connecting member 9 is constructed by screwing and fastening the bolts 23 inserted through the through holes 20 of the mounting seats 18. At this time, with respect to the mounting seats 18 attached to the column members 6 and 7 of the partitioning vertical frame 2b located at the boundary between the two groups G1 and G2, the horizontal connection located on both sides of the column members 6 and 7 The attachment portions 11 and 12 of the material 9 are overlapped on the horizontal upper surface (flat side surface 21a) of the attachment seat 18, and both attachment portions are attached by one bolt 23 inserted through the attachment holes 14 of both attachment portions 11 and 12. 11 and 12 are attached to one mounting seat 18.

  If the horizontal connecting members 9 are installed between the front supporting members 6 and the rear supporting members 7 of the vertical frames 2, 2 a to 2 c, the horizontal brace member 10 is provided between the front and rear horizontal connecting members 6, 7. The horizontal connecting frames 3a and 3b are completed, and the horizontal brace material 10 has braces provided at both ends thereof adjacent to the end portions 11 to 13 of the horizontal connecting material 9. Of the material mounting holes 15, the end portions 10 a of the horizontal brace material 10 overlap with the corresponding brace material mounting holes 15, and the mounting holes 10 b provided in the end portions 10 a of the horizontal brace material 10 and the brace material The countersunk bolt 24 can be inserted from the bottom upward through the mounting hole 15, and the nut 25 can be screwed and fastened to be attached to the horizontal connecting member 9.

  Since the horizontal connecting member 9 is a flat bar whose plate surface is positioned up and down as described above, it is attached to the column members 6 and 7 of the partitioning vertical frame 2b located at the boundary between the two groups G1 and G2. Even if the mounting portions 11 and 12 of the horizontal coupling member 9 positioned on both sides of the support columns 6 and 7 are mounted on the mounting seat 18 in a state of being overlapped with each other, one horizontal having the end portion 12 on the upper side. There is almost no risk of adversely affecting the strength surface, the mounting work surface, and the like simply by slightly deforming the connecting material 9 slightly (by the thickness) in the region of one section on the end 12 side. However, as shown in FIG. 5 and FIG. 6, the end portion 12 that is attached to be overlapped on the end portion 11 of the adjacent horizontal connecting member on one mounting seat 18 is provided with a bent portion 12 a in front of it. Can be increased by approximately the plate thickness. Further, as shown in FIGS. 6 and 7, the end portion 10 a of the horizontal brace material 10 is also provided with a bent portion 10 c in front of the end portion 10 a so as to be increased by about the plate thickness. The portion between the members 9 can be configured to be positioned at substantially the same level as the front and rear horizontal connecting members 9.

  In the above-described embodiment, the mounting seat 18 is configured by the prismatic head portion of the bolt 19, but the mounting seat mounting bolt and the mounting seat can be configured separately. For example, the mounting seat 26 shown in FIG. 8 includes a horizontal plate portion 27 including a horizontal upper surface 27 a that supports the end portions 11 to 13 of the horizontal coupling member 9 and a mounting hole 28, and a bent plate connected from the horizontal plate portion 27. The vertical plate part 31 provided with the through-hole 30 of the front-back horizontal direction through which the installation seat mounting bolt 29 is inserted can be comprised. In this case, the mounting hole 28 is formed by, for example, burring so that the hole length is larger than the plate thickness and the thread groove is processed, and the horizontal connecting member 9 is attached to the horizontal connecting member without using a nut as in the above embodiment. Although it is possible to configure so that it can be attached with the bolt 23 for use, it is desirable to use the nut 32 together as shown in the drawing in order to increase the attachment strength. Further, the mounting seat mounting bolt 29 is passed through the column members 6 and 7 in a state where the elastic seat plate 22 (see FIGS. 6 and 7) is loosely fitted to the mounting seat mounting bolt 29 inserted through the through hole 30. The mounting seat 26 can be attached to the column members 6 and 7 so that the horizontal plate 27 is horizontal above the bolts 29 by screwing and fastening to the screw holes 16, but the vertical plate 31 is shown in the figure. At least one side (both sides in the illustrated example) is provided with a bent side 31a that engages with the sides of the support members 6 and 7 and prevents rotation, and the mounting seat 26 is used for mounting the mounting seat. Rotation around the bolt 29 can be prevented.
