MODE FOR CARRYING OUT THE INVENTION

[0011] Hereinafter, a scaffolding member transportation system and a scaffolding member transportation plate according to an embodiment of the present disclosure will be described with reference to FIGS. 1 to 6. Instructions for using the scaffolding component transport system. (Overall configuration of the scaffolding member transportation system) (Overall configuration of the scaffolding member transportation system) As shown in FIG. 1, the scaffolding member transportation system 1 of this embodiment is mounted on the loading platform 201 of the truck 200. The scaffolding member transportation system 1 is used when transporting the scaffolding member 100 which is a member constituting the temporary scaffolding. The transportation of the scaffolding member 100 is performed, for example, between a storage location such as a warehouse and a usage location such as a construction site. The scaffolding member 100 transported from the storage location to the usage location and unloaded is assembled by an operator to become a temporary scaffolding. On the other hand, the temporary scaffolding after use is disassembled by an operator, loaded as the scaffolding member 100, and transported from the usage location to the storage location. The scaffolding member transportation system 1 has a plurality of racks 2 and a plate (scaffolding member transportation plate) 3.

[0012] (Configuration of the rack) Each of the plurality of racks 2 can support a scaffolding member 100. Examples of the scaffolding member 100 that can be supported by the rack 2 include a support column 101 made of a single-pipe or the like, a scaffolding board 102 as a steel or wooden tread board, an auxiliary member (not shown), a safety net (not shown), and the like. Examples of the auxiliary member include a jack base, a bracket, and the like. In the present embodiment, the rack 2 suitable for a relatively long scaffolding member 100 such as the support column 101 and the scaffolding board 102 will be described as an example.

[0013] FIG. 2 is a perspective view showing a schematic configuration of a rack of a scaffolding member transport system according to an embodiment of the present disclosure. As shown in FIG. 2, each rack 2 has a support frame 21, a plurality of legs 22, and a plurality of columns 23. The rack 2 can be formed, for example, by joining a plurality of steel pipes having a rectangular or circular cross section by welding or the like.

[0014] The support frame 21 is formed in a rectangular shape when viewed in the vertical direction Dv. The support frame 21 is formed, for example, by arranging four steel pipes in a rectangular shape in a plan view and joining the ends of these four steel pipes to each other. The support frame 21 has a pair of frame members 21a, 21a and a pair of frame members 21b, 21b. The pair of frame members 21a, 21a extend in the short side direction Db of the support frame 21 and are provided apart from each other in the long side direction Da. The pair of frame members 21b, xxb extend in the long side direction Da of the support frame 21 and are provided apart from each other in the short side direction Db of the support frame 21.

[0015] Rack 2 is capable of supporting scaffolding members 100 on the support frame 21. The scaffolding member 100 illustrated in Figure 2 is placed on the support frame 21 so as to extend in the long side direction Da of the support frame 21. This scaffolding member 100 is supported by being spanned across a pair of frame members 21a, 21a of the support frame 21. In other words, the support frame 21 is formed in a rectangular shape when viewed from above, with a size corresponding to the size and shape of the scaffolding member 100 to be supported. In this embodiment, one scaffolding member transport system 1 has multiple racks 2, but the size of the multiple racks 2 when viewed from the vertical direction Dv may differ according to the type (size, shape) of the scaffolding member 100 to be supported. The support frame 21 may also be covered with a plate or the like to close the space in the center.

[0016] The legs 22 extend downward from the four corners of the support frame 21. Engaged portions 24 are formed at the lower ends of the legs 22. In other words, multiple (four) engaged portions 24 are provided at the lower ends of the rack 2. These multiple engaged portions 24 are formed to be engageable with engaging portions 35 (described later) provided on the plate 3. In this embodiment, the engaged portion 24 is, for example, a recess that extends upward from the lower end of the leg 22.

[0017] Multiple columns 23 extend upward from, for example, the four corners of the support frame 21. The multiple columns 23 restrict the displacement of the scaffolding members 100 supported on the support frame 21 outward from the support frame 21. In other words, the multiple columns 23 prevent the scaffolding members 100 from falling laterally (in the short-side direction Db in Figure 2) from the support frame 21. The length of the columns 23 in the vertical direction Dv may vary depending on the type and number of scaffolding members 100 mounted on each rack 2. In addition to the four corners of the support frame 21, the columns 23 may also extend upward from the middle of each frame member 21a, 21b of the support frame 21 in the extension direction.

[0018] (Plate composition) Figure 3 is a plan view showing a scaffolding member transport plate according to the present disclosure mounted on the bed of a truck. As shown in Figures 1 and 3, the plate 3 can be loaded onto the cargo bed 201 of the truck 200. The plate 3 can accommodate multiple racks 2 that support the scaffolding members 100. The plate 3 is sized to be loaded onto the cargo bed 201. For example, the length of the first direction D1 intersecting the vertical direction Dv is about 2.5m, and the length of the second direction D2 intersecting the vertical direction Dv and the first direction D1 is about 2m. The size of the plate 3 can be appropriately changed according to the size of the cargo bed 201 of the truck 200. In this embodiment, the plate 3 can be loaded onto the cargo bed 201, for example, with the first direction D1 being the front-rear direction FR of the truck 200, and the second direction D2 being the width direction W of the truck 200. In this embodiment, the plate 3 is sized to be loaded onto the cargo bed 201 and to be lifted and lowered by a forklift. Furthermore, to allow for lifting and lowering by a crane or similar device, ring members such as eye bolts may be provided at the four corners of plate 3 or at the top of the columns 23 of rack 2.

[0019] Figure 4 is a perspective view showing the schematic configuration of a scaffolding member transport plate according to an embodiment of this disclosure. As shown in Figure 4, the plate 3 has a rack mounting section 31, legs 32, and a plurality of engaging sections 35.

[0020] The rack mounting section 31 is formed in the shape of a rectangular plate when viewed from the vertical direction Dv. The rack mounting section 31 can be formed by combining, for example, steel frames, steel pipes, steel plates, etc. As shown in Figure 3, the rack mounting section 31 is large enough to accommodate multiple racks 2 side by side. In this embodiment, the example shows that multiple racks 2 can be mounted on the rack mounting section 31 in the front-rear direction FR and the width direction W of the truck 200.

[0021] As shown in Figure 4, the legs 32 are provided below the rack mounting section 31. The legs 32 support the rack mounting section 31 from below. Multiple legs 32 are provided at intervals in the first direction D1 as illustrated in this embodiment. The legs 32 illustrated in this embodiment are made of rectangular prism-shaped timbers that have a predetermined height in the vertical direction Dv and extend in the second direction D2. The multiple legs 32 may be provided, for example, below the four corners of the rack mounting section 31. When the plate 3 is placed on the truck bed 201 or the ground, the multiple legs 32 form a gap between the rack mounting section 31 and the truck bed 201 or the ground, into which the forks of a forklift (not shown) can be inserted.

[0022] Furthermore, in this embodiment, the lower surface of the rack mounting section 31 is provided with fork insertion sections 33 between a plurality of legs 32 into which the fork tines of a forklift are inserted. By providing the fork insertion sections 33, lateral slippage of the fork tines is suppressed when the plate 3 is lifted by the forklift. Note that the fork insertion sections 33 may be provided as needed, and may be omitted, for example.

[0023] Multiple engaging portions 35 are provided on the rack mounting portion 31. The multiple engaging portions 35 can engage with multiple engaged portions 24 (see Figure 2) that each of the multiple racks 2 has. In this embodiment, each of the multiple engaging portions 35 is a projection that protrudes upward from the upper surface of the rack mounting portion 31. Each engaging portion 35 may be a rectangular prism shape extending in the vertical direction Dv, or it may be cylindrical. Each of the multiple engaging portions 35 is inserted into the engaged portion 24 of the rack 2 from below. By engaging with the engaged portions 24 provided at the four corners of each rack 2, the multiple engaging portions 35 suppress misalignment of the rack 2 on the rack mounting portion 31.

[0024] As shown in Figure 3, the multiple engaging portions 35 are provided on the rack mounting portion 31, aligned with the positions where each of the multiple racks 2 should be placed. In this embodiment, multiple racks 2 can be placed on the rack mounting portion 31 in the longitudinal direction FR and the width direction W of the track 200. The multiple engaging portions 35 are provided in positions that overlap with the engaged portions 24 provided at the four corners of each rack 2 when viewed from the vertical direction Dv (in other words, positions where engagement is possible) when each of the multiple racks 2 is positioned where it should be placed.

[0025] In this embodiment, multiple racks 2A to 2D of different sizes can be placed on the rack mounting section 31. Multiple engaging sections 35 are provided at multiple positions corresponding to the respective sizes of the multiple types of racks 2 (2A to 2D).

[0026] In this embodiment, some of the engagement portions 35K among the multiple engagement portions 35 are shared between multiple types of racks 2A and racks 2D that have different sizes in the short-side direction Db. Specifically, they are designed to engage with both two of the engagement portions 24 at the four corners of rack 2A and two of the engagement portions 24 at the four corners of rack 2D, so that racks 2A and racks 2D can be placed at the same position on the rack mounting portion 31. The number and position of the multiple engaging parts 35 provided on the rack mounting section 31 can be changed as appropriate. For example, when loading multiple plates 3 onto the cargo bed 201 of the truck 200, the number and position of the multiple engaging parts 35 may differ among the multiple plates 3.

[0027] As shown in Figures 1 and 3, each of the multiple racks 2 placed on the rack mounting section 31 is equipped with scaffolding members 100 of different types. In addition, each rack 2 is equipped with multiple scaffolding members 100. In this embodiment, an example is shown where multiple scaffolding boards 102 of the same size are mounted on rack 2A, multiple support columns 101 of the same length are mounted on rack 2B, and multiple support columns 101 of a different length than those mounted on rack 2B are mounted on rack 2C. By mounting the scaffolding members 100 by type on multiple racks 2 in this way, it is easy to manage the scaffolding members 100 in storage locations and at usage locations such as construction sites.

[0028] In this embodiment, two plates 3 are loaded side-by-side in the front-to-back direction FR on a single cargo bed 201. The number of plates 3 loaded side-by-side on the cargo bed 201 can be appropriately changed depending on the size of the cargo bed 201, the size of the plates 3, etc. Alternatively, multiple plates 3 may be loaded on the cargo bed 201 in the width direction W of the truck 200.

[0029] As shown in Figure 3, when multiple plates 3 are arranged in the front-rear direction FR of the truck 200 and loaded onto the cargo bed 201, the multiple plates 3 can support long scaffolding members 100L, such as single pipes, by straddling one plate 3A and another plate 3B that is loaded onto the cargo bed 201 alongside this plate 3A. For this reason, the rack mounting section 31 has a long material mounting section 36 in a part thereof on which long scaffolding members 100L can be supported. The long material mounting section 36 may be configured to support long scaffolding members 100L using racks 2. Alternatively, the long material mounting section 36 may be configured to support long scaffolding members 100L without using racks 2. When the scaffolding member 100L is placed on the long material placement section 36 without using the rack 2, in order to prevent the long scaffolding member 100L from shifting position in the width direction W of the truck 200 and falling, projections or support columns (not shown) extending upward from the rack placement section 31 may be provided on the rack placement section 31 of the long material placement section 36.

[0030] Figure 5 is a side view showing an example of a state in which multiple racks are placed on a scaffolding member transport plate according to the embodiment of this disclosure. As shown in Figure 5, multiple racks 2 may be mounted on the rack mounting section 31 in a stacked manner in the vertical direction Dv. For example, the lower rack 2C and the upper rack 2K may be stacked directly without anything in between. In this case, as shown in Figure 2, the lower rack 2C has an upper end engaging portion 25 that protrudes upward at the upper end of the column 23. The upper end engaging portion 25 of the lower rack 2C engages with the engaged portion 24 of the leg 22 of the upper rack 2K.

[0031] Figure 6 is a perspective view showing a pole member of a scaffolding member transport system according to an embodiment of this disclosure. Furthermore, a pole member 5 extending in the vertical direction Dv may be provided between the lower rack 2A and the upper rack 2T. As shown in Figures 5 and 6, the pole member 5 has a lower connecting portion 51 and an upper engaging portion 52. The lower connecting portion 51 is formed to be connectable to an upper engaging portion 25 provided at the upper end of the column 23 of the upper rack 2. The lower connecting portion 51 is, for example, a recess into which the upper engaging portion 25 of the column 23 is inserted from below. The upper engaging portion 52 is formed to be engageable with an engaged portion 24 provided at the lower end of the leg 22 of the rack 2. The upper engaging portion 52 is, for example, inserted into the engaged portion 24 from below.

[0032] Multiple types of pole members 5 with different vertical lengths Dv may be provided. By appropriately selecting the vertical length Dv of the pole member 5 installed between the lower rack 2A and the upper rack 2T, the vertical distance Dv between rack 2A and rack 2T can be changed. This configuration allows for adjustment of the stacking height of the scaffolding members 100 that can be placed on the support frame 21 of the lower rack 2A. Here, the pole member 5 can also be installed so as to extend upward from the uppermost rack. In this case, it is possible to prevent the scaffolding members 100 supported by the uppermost rack from falling.

[0033] Furthermore, as shown in Figure 6, the pole member 5 may be extendable and retractable in the vertical direction Dv. In this case, the pole member 5 has an outer cylinder 53 and an inner cylinder 54 inserted into the outer cylinder 53. The pole member 5 is extendable and retractable in the vertical direction Dv by moving the inner cylinder 54 in the vertical direction Dv relative to the outer cylinder 53. The length of the pole member 5 in the vertical direction Dv can be fixed by engaging the outer cylinder 53 and the inner cylinder 54 using appropriate pins or projections. The pole member 5 may also be made immobile in the vertical direction Dv. In addition, multiple pole members 5 may be connected in the vertical direction Dv, and the height between adjacent racks 2A and 2T in the vertical direction Dv may be adjusted by adjusting the number of connected pole members 5.

[0034] In the scaffolding member transport system 1 described above, when loading the scaffolding members 100 onto the truck bed 201 of the truck 200 at the storage or usage location, the plate 3 is placed on the ground, and multiple racks 2 are mounted on the rack mounting section 31. At this time, a predetermined number of scaffolding members 100 are pre-loaded onto each rack 2. Therefore, multiple scaffolding members 100 can be loaded onto the plate 3 along with each rack 2. Alternatively, after mounting the racks 2 on the rack mounting section 31, the scaffolding members 100 may be loaded onto the support frames 21 of the racks 2. Furthermore, at the storage location, the scaffolding members 100 may be loaded onto the racks 2 and stored together with the racks 2. When the scaffolding members 100 are loaded onto the racks 2 and stored together with the racks 2 in this manner, the racks 2 with the scaffolding members 100 loaded can be placed directly onto the plate 3, thereby reducing the burden on workers. After a predetermined number of racks 2 and long scaffolding members 100L are placed on the rack mounting section 31, the plate 3 is loaded onto the truck bed 201 of the truck 200 using a forklift.

[0035] On the other hand, when unloading the scaffolding members 100 from the truck bed 201 of the truck 200 at the place of use or storage, the long scaffolding members 100L, which are mounted to straddle multiple (two) plates 3, are unloaded first. This makes it possible to detach the multiple plates 3 individually from the truck bed 201. After that, the plates 3, on which multiple racks 2 are mounted on the rack mounting section 31, are sequentially unloaded from the truck bed 201 using a forklift.

[0036] (Effects and Benefits) In the scaffolding member transport system 1 and plate 3 of the above embodiment, multiple racks 2 can be placed on the rack mounting section 31 simultaneously. Each of the multiple racks 2 is held in a predetermined position on the rack mounting section 31 by engaging multiple engaging sections 35 with multiple engaged sections 24. By loading and unloading such a plate 3 onto the cargo bed 201 of the truck 200 using a forklift or the like, multiple racks 2 can be loaded and unloaded together. As a result, the effort required to load and unload the scaffolding members 100 onto the truck 200 can be reduced, and the burden on workers can be lessened.

[0037] Furthermore, in the above embodiment, the plate 3 is provided with engaging portions 35 at multiple positions corresponding to the type of rack 2. This configuration allows multiple types of racks 2 of different sizes to be mounted on the plate 3.

[0038] Furthermore, in the above embodiment, by providing the pole member 5, when stacking multiple racks 2 in the vertical direction Dv, the distance between the upper and lower racks 2 can be increased.

[0039] Furthermore, in the above embodiment, by making the pole member 5 extendable and retractable, the spacing between the upper and lower racks 2 can be easily adjusted when stacking multiple racks 2 in the vertical direction Dv.

[0040] Furthermore, in the above embodiment, the plate 3 has a long material placement section 36 on which a long scaffolding member 100L can be placed. With this configuration, when multiple plates 3 are arranged in the front-to-back direction FR on the cargo bed 201 of the truck 200, a long scaffolding member 100L that spans multiple plates 3 can be transported.

[0041] (First modified example of the embodiment) In the above embodiment, a rack 2 having a shape suitable for relatively long scaffolding members 100 such as support columns 101 and scaffolding boards 102 was described as an example. However, among the multiple types of racks, including rack 2 in the above embodiment, some racks may include racks suitable for transporting auxiliary members such as jack bases and brackets. In the following description of the first modification of the embodiment, the rack suitable for transporting auxiliary members will simply be referred to as the auxiliary member rack 7. In this first modification of the embodiment, the same reference numerals are used for the same parts as in the above embodiment, and redundant explanations are omitted.

[0042] (Auxiliary component rack) Figure 7 is a perspective view of an auxiliary member rack in a first modified example of the embodiment of the present disclosure. As shown in Figure 7, the auxiliary member rack 7 in this first modified example is capable of supporting an auxiliary member as a scaffolding member 100 and has a plurality of engaging portions 24 at its lower end. The auxiliary member rack 7 has a plurality of legs 22, a plurality of columns 23, a bottom wall portion 26, and a side wall portion 27. The auxiliary member rack 7 may also have a support frame 21 (see Figure 2) that supports the bottom wall portion 26 from below.

[0043] (Bottom wall section) The bottom wall portion 26 can support auxiliary members, which serve as scaffolding members 100, from below. In this first modified example, the bottom wall portion 26 is formed in a rectangular plate shape when viewed from above, with columns 23 positioned at each of the four corners. The bottom wall portion 26 can be made of plate material such as a flat plate or a corrugated plate.

[0044] (Side wall section) The side wall portion 27 extends upward from the bottom wall portion 26. The side wall portion 27, together with the bottom wall portion 26, partitions the accommodation space S. The accommodation space S is capable of accommodating auxiliary members as scaffolding members 100. In this first modified example, the side wall portion 27 extends upward from each of the four sides of the bottom wall portion 26. These four side wall portions 27 are arranged in a rectangular cylindrical shape in top view, surrounding the outer edge of the bottom wall portion 26. Columns 23 are positioned at each corner of the rectangle formed by the four side wall portions 27 in top view. In this way, the accommodation space S is partitioned by the four side wall portions 27 and one bottom wall portion 26.

[0045] (Door component) The side wall portion 27 is equipped with an openable and closable door member 28. In this first modified example, the auxiliary member rack 7 has a door member 28 on one of the two opposing sets of side wall portions 27A. In addition, the side wall portion 27A of this first modified example is equipped with a fixed wall portion 29 that cannot be opened or closed, directly below the door member 28.

[0046] In this first modification, the door member 28 is supported on the fixed wall 29 via a hinge portion 30 having an axis extending along the side wall portion 27A in a top view. In this first modification, the door member 28 is supported on the hinge portion 30 so as to be able to swing outward toward the containment space S. In this first modification, the door member 28 is displaceable between a closed position in which its upper edge portion 28a is at its highest position and an open position in which its upper edge portion 28a is at a lower position than the closed position.

[0047] (Fixed wall part) The fixed wall portion 29 is formed in a range from the position of the bottom wall portion 26 in the vertical direction to the midpoint of the entire side wall portion 27A. A door member 28 is attached to the area of ​​the side wall portion 27A directly above the fixed wall portion 29 so as to be openable and closable. In other words, the upper half of the side wall portion 27A is the door member 28, and the lower half of the side wall portion 27A is the fixed wall portion 29. Furthermore, the auxiliary member rack 7 of this first modified example is provided with a latch 38 that allows the door member 28 to be held in the closed position. Also, similar to the rack 2 of the above embodiment, multiple auxiliary member racks 7 can be stacked vertically.

[0048] (Effects of the first torture method) According to the first modified example of the above embodiment, the presence of a bottom wall portion 26 makes it possible to stack multiple auxiliary members that are shorter and smaller than the support columns 101 and scaffolding boards 102 of the scaffolding member 100 on the bottom wall portion 26, making it possible to easily transport the auxiliary members. In addition, since the side wall portion 27 restricts the lateral displacement of the auxiliary members in the storage space S, the auxiliary members can be loosely stacked in the storage space S. Furthermore, by opening the door member 28, the auxiliary members stored in the storage space S can be easily removed. In addition, since a fixed wall portion 29 is provided directly below the door member 28, it is possible to suppress the collapse of the load of auxiliary members when the door member 28 is opened.

[0049] Furthermore, in this first modified example of the auxiliary member rack 7, door members 28 are provided on two opposing side wall sections 27A. Therefore, by opening both of these opposing door members 28, it becomes possible to stack long members exceeding the distance between the two side wall sections 27A on the auxiliary member rack 7.

[0050] The fixed wall portion 29 may be provided as needed. For example, the fixed wall portion 29 may be omitted, and the entire side wall portion 27A may be formed by the door member 28. Furthermore, the opening and closing direction of the door member 28 is not limited to the above-described direction. For example, the door member 28 may be rotated around an axis extending in the vertical direction Dv. Moreover, the door member 28 is not limited to a configuration that opens and closes via a hinge portion 30. An example of a configuration without a hinge portion 30 is one in which the door member 28 slides. Furthermore, although the example shows a case where a door member 28 is provided on one pair of side wall portions 27, a door member 28 may be provided on all side wall portions 27, or a door member 28 may be provided on only one side wall portion 27. Also, the side wall portion 27 is not limited to being fixed to the column 23. For example, it may be detachably attached to the auxiliary member rack 7. Furthermore, although the example given illustrates a case where the bottom wall portion 26 and the side wall portion 27 are formed from plate-like members, they may also be formed from perforated metal or mesh-like members.

[0051] (Second modified example of the embodiment) In the above embodiment and first modification, the cases of stacking racks 2 of the same type in the vertical direction Dv and stacking auxiliary member racks 7 in the vertical direction Dv were described, respectively. However, the configuration is not limited to these. In the second modification of this embodiment, the case in which different types of racks are stacked in the vertical direction Dv is described. In this second modification of the embodiment, the same reference numerals are used for the same parts as in the above embodiment, and redundant explanations are omitted. In this second modification, the case in which the bottom wall portion 26 and the side wall portion 27 are formed of a mesh-like material is illustrated, but instead of a mesh-like material, a plate-like material or perforated metal may be used.

[0052] As shown in Figures 8 and 9, the scaffolding member transport system 1 in the second modified embodiment has a plurality of racks 2 and a plate (scaffolding member transport plate) 3. The plurality of racks 2 include racks 2 suitable for relatively long scaffolding members 100 such as scaffolding boards 102 (hereinafter simply referred to as rack 2E) and auxiliary member racks 107 suitable for transporting the auxiliary members described above. In this second modified embodiment, the auxiliary member rack 107 and rack 2E each have a rectangular outline in plan view. The longitudinal dimension of the auxiliary member rack 107 in plan view is larger than the longitudinal dimension (front-to-back direction FR in this modified embodiment) of rack 2E in plan view.

[0053] In this second modification, rack 2E and auxiliary member rack 107 are mounted side by side on plate 3. The longitudinal directions of rack 2E and auxiliary member rack 107 are the same. This second modification illustrates the case where the longitudinal directions of rack 2E and auxiliary member rack 107 coincide with the longitudinal direction FR of track 200. Rack 2E and auxiliary member rack 107 are positioned with a small gap between them in the width direction W of track 200.

[0054] As shown in Figures 9 and 10, the auxiliary member rack 107, like the auxiliary member rack 7 of the first modified example described above, has a plurality of legs 22, a plurality of columns 23, a bottom wall portion 26, and side wall portions 27. In addition to the auxiliary member rack 7 of the first modified example, the auxiliary member rack 107 further has a support frame 21 and a lower engaging column 55. In this second modified example, of the two side wall portions 27 extending in the longitudinal direction of the auxiliary member rack 107, only one is a side wall portion 27A having a door member 28. This door member 28 is positioned facing outward in the width direction W of the truck 200 when mounted on the cargo bed 201 of the truck 200, allowing auxiliary members to be inserted into and removed from the auxiliary member rack 107 when mounted on the cargo bed 201. The number of side wall portions 27A in the auxiliary member rack 107 is not limited to one.

[0055] The lower engaging column 55 is positioned in the middle of the frame member 21b that extends in the longitudinal direction of the auxiliary member rack 107 within the support frame 21. Two lower engaging columns 55 are provided between the two legs 22, spaced apart in the front-rear direction FR. The lower engaging column 55 comprises a column body 55a and an upper end engaging portion 55b. The column body 55a extends downward from the bottom wall portion 26. The column body 55a has a length from the bottom wall portion 26 to the upper surface of the plate 3. The upper end engaging portion 55b protrudes above the bottom wall portion 26. In a plan view, the upper end engaging portion 55b is located within the housing space S enclosed by the side wall portion 27. The upper end engaging portion 55b is formed to be insertable into the lower connecting portion 51 of the pole member 5 described above.

[0056] In the second modified example, the length of the pole member 5 is such that, when the pole member 5 is inserted into the upper end engaging portion 55b, the upper end engaging portion 52 of the pole member 5 is located above the upper edge of the side wall portion 27. In this second modified example, when the pole member 5 is attached to the lower engaging column 55, the sum of the length of the lower engaging column 55 and the length of the pole member 5 is the same as the length of the column 23 of the auxiliary member rack 107. However, the sum of the length of the lower engaging column 55 and the length of the pole member 5 may be greater than the length of the column 23 of the auxiliary member rack 107. Preferably, the sum of the length of the lower engaging column 55 and the length of the pole member 5 is a length corresponding to the height of the rack 2E which is arranged alongside the auxiliary member rack 107 in the width direction W.

[0057] The length L1 between the two lower engaging columns 55 is set to be the same length as the length L2 (see Figure 9) between the columns 23 of rack 2E, which are spaced apart in the longitudinal direction. Rack 2E is rack 2, which is arranged alongside the auxiliary member rack 107 in the width direction W. In the front-rear direction FR, the position of the column 23 located in front of rack 2E is the same as the position of the lower engaging column 55 located in front, and the position of the column 23 located in rear is the same as the position of the lower engaging column 55 located in rear.

[0058] (Effects of the second modification) According to the second modified example of the above embodiment, the pole member 5 can be attached to the lower engaging column 55. Therefore, in a plan view, a rack 2T having columns 23 at the positions of the two columns 23 of rack 2E and the two lower engaging columns 55 of auxiliary member rack 107 can be stacked above rack 2E and auxiliary member rack 107 (see Figures 8 and 9). Furthermore, even if rack 2T is of a different size from rack 2E and auxiliary member rack 107, it can be positioned to straddle rack 2E and auxiliary member rack 107, and the engaged portion 24 of rack 2T can be engaged with the upper end engaging portion 25 of rack 2E and the upper end engaging portion 52 of auxiliary member rack 107, respectively.

[0059] Although the explanation described using the case where the lower engaging column 55 is provided on the auxiliary member rack 107 as an example, it is not limited to the auxiliary member rack 107. For example, the lower engaging column 55 may be provided on the rack 2 that has a relatively larger longitudinal dimension among the racks 2 arranged side by side. Furthermore, the placement of the lower engaging column 55 is not limited to the middle of the frame member 21b. Depending on the size of the stacked rack 2T, it may be placed, for example, closer to the center in the width direction W than the frame member 21b. Furthermore, an example was given in which two lower engaging columns 55 are provided on a single auxiliary member rack 107. However, the number of lower engaging columns 55 provided on a single auxiliary member rack 107 is not limited to two; any even number of two or more is acceptable. Furthermore, although the example given shows the lower engaging column 55 being provided only on one side in the width direction W of the auxiliary member rack 107, it may also be provided symmetrically in the width direction W (for example, symmetrically left and right if the longitudinal direction is the front-to-back direction FR).

[0060] (Other embodiments) Although embodiments of this disclosure have been described in detail above with reference to the drawings, the specific configuration is not limited to these embodiments and may include design changes and the like that do not depart from the gist of this disclosure. In the above embodiment and its modified form, the engaged portion 24 is a recess and the engaging portion 35 is a protrusion, but the invention is not limited to this, and for example, the engaged portion 24 may be a protrusion and the engaging portion 35 may be a recess. Furthermore, the above embodiments and their modifications illustrate the case in which multiple racks 2, 2A-2D, 2K, 2T, and auxiliary member racks 7 are arranged and placed on a single plate 3, 3A, 3B for transport. However, plates 3, 3A, and 3B only need to be formed to accommodate multiple racks and auxiliary member racks arranged side by side; for example, only one rack 2 or auxiliary member rack 7 may be placed on a single plate 3, 3A, or 3B.
