Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, from the viewpoint of transportability and the like, it is conceivable to divide the shelf support into a plurality of column members in the axial direction.

[0005] However, if the shelf support is divided into a plurality of column members in the vertical direction, there is a concern that the strength will decrease at the joints of adjacent column members.

[0006] As a countermeasure, for example, it is conceivable to partially reinforce the joints of the column members with a gusset plate or the like.

[0007] However, in this case, the joints of the column members may become partially thick, and the designability of the shelf support may decrease.

[0008] In consideration of the above facts, an object of the present invention is to enhance the designability of the shelf support while ensuring the strength of the shelf support.

Means for Solving the Problems

[0009] Regarding the first aspectThe shelf comprises a pair of first columns and a pair of first shelves mounted on the pair of first columns, and a plurality of first shelf sections arranged vertically, and a pair of second columns and a pair of second shelves mounted on the pair of second columns, and a second shelf section arranged vertically next to the first shelf sections, wherein adjacent first columns and second columns are joined with the joints between the first columns and the joints between the second columns offset vertically.

[0010] First aspect The shelf in question has a plurality of first shelf sections arranged vertically and a plurality of second shelf sections arranged vertically next to the first shelf sections. Each first shelf section has a pair of first column members and a first shelf board installed on the pair of first column members. Each second shelf section has a pair of second column members and a second shelf board installed on the second column members.

[0011] Here, the shelf support is formed by joining the adjacent first and second column members. In other words, the shelf support is divided into a first column member and a second column member. By dividing the shelf support into a first column member and a second column member in this way, the transportability of the shelf support (first column member and second column member) is improved.

[0012] Furthermore, adjacent first and second column members are joined with their joints vertically offset from each other. This reinforces the joint between the first column members with the second column member, and reinforces the joint between the second column members with the first column member. Consequently, the reduction in strength of the shelf support is suppressed.

[0013] Furthermore, in this invention, since there is no need to partially reinforce the joints between the first and second column members with splices or the like, the partial thickening of the joints between the first and second column members is suppressed. Therefore, the aesthetic design of the shelf support can be enhanced.

[0014] Thus, the present invention makes it possible to enhance the aesthetic design of the shelf support while ensuring its strength.

[0015] Regarding the second aspect The shelf is Regarding the first aspect In the shelf, the first shelf section is a unit formed by integrating a pair of first column members and the first shelf board, and the second shelf section is a unit formed by integrating a pair of second column members and the second shelf board.

[0016] Second aspect In this shelf, the first shelf section is a unit in which a pair of first column members and a first shelf board are integrated. The second shelf section is a unit in which a pair of second column members and a second shelf board are integrated. This allows the shelf to be easily assembled, for example, by joining the first column members of the first shelf section and the second column members of the second shelf section in the shelf installation space.

[0017] Furthermore, by making the first and second shelf sections into separate units, the assembly time required in the shelf installation space is reduced. Consequently, the ease of assembling the shelves is improved.

[0018] Regarding the third aspect The shelf is Regarding the second aspect In the shelf, a pair of first column members and the first shelf are formed from metal plates and integrated by welding, and a pair of second column members and the second shelf are formed from metal plates and integrated by welding.

[0019] Third aspect In this shelf, a pair of first columns and a first shelf are made of metal plates, and a pair of second columns and a second shelf are also made of metal plates. This allows the first columns, first shelf, second columns, and second shelf to be made thinner while maintaining strength.

[0020] Furthermore, in this invention, a pair of first column members and a first shelf are integrated by welding. As a result, in this invention, the joint between the pair of first column members and the first shelf can be simplified compared to the case in which the pair of first column members and the first shelf are bolted together.

[0021] Similarly, in the present invention, a pair of second column members and a second shelf board are integrated by welding. Thereby, in the present invention, compared with the case where a pair of second column members and a second shelf board are bolted together, the joint portion of the pair of second column members and the second shelf board can be simplified.

[0022] Thus, in the present invention, it is possible to form a simple shelf while ensuring strength.

[0023] Regarding the fourth aspect The shelf is First aspect ~ Third aspect any one of related to In the shelf, the first column member and the second column member are fixed to the upper and lower casings.

[0024] Fourth aspect According to the shelf according to, the first column member and the second column member are fixed to the upper and lower casings. Thereby, the fall of the shelf during an earthquake is suppressed. Further, in the present invention, the degree of freedom of the installation location of the shelf is improved compared with the case where the shelf is fixed to a wall or the like.

[0025] Regarding the fifth aspect The shelf includes a pair of shelf columns made of metal plates that are erected at intervals from each other and fixed to the upper and lower casings, and a shelf board made of a metal plate that is installed on the pair of shelf columns and projects forward and backward from the shelf columns.

[0026] Fifth aspect According to the shelf according to, by making the pair of shelf columns and the shelf board made of metal plates, the strength can be ensured while making the shelf columns and the shelf board thinner. Further, by making the shelf board project forward and backward from the pair of shelf columns, the designability of the shelf can be enhanced.

Effect of the Invention

[0027] As described above, according to the present invention, while ensuring the strength of the shelf columns, the designability of the shelf columns can be enhanced.

[Figure 8] This is a perspective view showing a modified example of a shelf according to one embodiment. [Figure 9] This is an elevation view corresponding to Figure 4, which shows a modified example of the shelf unit according to one embodiment. [Modes for carrying out the invention]

[0029] A shelf according to one embodiment will be described below with reference to the drawings.

[0030] (shelf) Figure 1 shows a shelf 10 according to this embodiment. The shelf 10 is, for example, a bookshelf. This shelf 10 has a plurality of shelf supports 12 arranged at intervals in the width direction, and a plurality of shelf boards 30 supported by adjacent shelf supports 12. The shelf 10 is formed by assembling a plurality of shelf units 20, a plurality of end shelf units 26, a plurality of column base units 50 (see Figure 6), and a plurality of column head units 80 (see Figure 7).

[0031] Note that shelves 10 can hold not only books but also various other items such as miscellaneous goods. Furthermore, arrows H, as shown in each diagram, indicate the vertical direction (height) of shelf 10, arrows W indicate the width direction, and arrows D indicate the front-to-back direction (depth).

[0032] (Shelf unit) As shown in Figure 2, the shelf unit 20 has a pair of column members 22 and a plurality of shelves 30 (two in this embodiment). The pair of column members 22 are formed in a plate shape from a metal plate (made of metal sheet) such as aluminum or steel.

[0033] A pair of column members 22 extend in the vertical direction (arrow H direction) of the shelf 10 and are arranged facing each other in the width direction (arrow W direction) of the shelf 10. The outer surface of each column member 22 (opposite the shelf board 30) is a joint surface 22A that connects to the column members 22 of other shelf units 20. Multiple shelf boards 30 are mounted on this pair of column members 22.

[0034] (Shelf board) Multiple shelves 30 are formed in a plate shape from metal plates (made of metal sheets) such as aluminum or steel. Furthermore, multiple shelves 30 are formed in a rectangular shape when viewed from above. These shelves 30 are arranged with gaps between them in the vertical direction of the shelf 10 and are mounted on a pair of column members 22 in two tiers, upper and lower.

[0035] As shown in Figure 3, notches 32 are formed at both ends of the shelf board 30 in the width direction of the shelf 10. In a plan view, the notches 32 are formed in a rectangular shape that extends in the front-to-back direction of the shelf 10.

[0036] The notches 32 are located on one side (for example, the rear side) of the shelf board 30 in the front-to-back direction. The column members 22 are welded into these notches 32. This integrates (unitizes) the pair of column members 22 and the multiple shelf boards 30. The shelf boards 30 also protrude forward and backward (in the front-to-back direction) from the pair of column members 22.

[0037] The end face 30E of the shelf board 30, where the notch 32 is formed, and the joint surface 22A of the column member 22 are flush. As a result, when the joint surfaces 22A of the column members 22 of adjacent shelf units 20 are overlapped in the width direction of the shelf 10, the end faces 30E of adjacent shelf boards 30 come into contact with each other, and adjacent shelf boards 30 are configured to be continuous in the width direction of the shelf 10.

[0038] In this context, the term "flush surface" refers not only to cases where the end face 30E of the shelf board 30 and the joint surface 22A of the column member 22 are exactly flush, but also to cases where there is a slight step between the end face 30E and the joint surface 22A due to manufacturing errors, etc. The notch 32 is optional.

[0039] Here, as shown in Figures 4 and 5, adjacent shelf units 20 in the width direction of shelf 10 are bolted together with the joining surfaces 22A of their respective column members 22 overlapping. Specifically, each shelf unit 20 has multiple screw holes 40 and multiple through holes 42 formed in the column member 22 at intervals in the vertical direction.

[0040] Multiple screw holes 40 are formed in the intermediate portion 22M of the column member 22 that connects adjacent shelves 30 in the vertical direction. The threaded portions of countersunk bolts 44 are screwed into these screw holes 40.

[0041] Multiple through holes 42 are formed in the upward extension 22U of the column member 22 that extends upward from the upper (topmost) shelf board 30, and in the downward extension 22D of the column member 22 that extends downward from the lower (bottommost) shelf board 30. Each through hole 42 has a countersunk hole 42A that accommodates the head of a countersunk bolt 44.

[0042] Multiple through holes 42 are aligned with threaded holes 40 formed in the column members 22 of other shelf units 20. In this state, by screwing countersunk bolts 44 into the threaded holes 40 through the through holes 42, the column members 22 of adjacent shelf units 20 in the width direction of the shelf 10 are bolted together. This forms the shelf support columns 12 of the shelf 10.

[0043] The arrangement and number of the screw holes 40 and through holes 42 can be changed as appropriate.

[0044] (End shelf unit) As shown in Figure 1, the multiple end shelf units 26 are arranged on one end of the shelf 10 in the width direction. The end shelf units 26 have a similar configuration to, for example, a divided unit obtained by dividing (cutting) the shelf unit 20 in the width direction of the shelf 10. These end shelf units 26 have a column member 22 and multiple protruding shelves 34.

[0045] The column member 22 is bolted to the column members 22 of other adjacent shelf units 20. This column member 22 is welded in a position where it fits into a notch (not shown) formed at the widthwise end of the shelf 10 in the protruding shelf board 34. Multiple protruding shelves 34 are cantilevered to the column member 22.

[0046] It is also possible to omit the protruding shelf board 34 from the end shelf unit 26 and form the end shelf unit 26 using only the column members 22.

[0047] (Shelf unit joining structure) Next, we will explain how to assemble the multiple shelf units 20.

[0048] Figures 4 and 5 disclose a plurality (four) of shelf units 20 arranged in the vertical and width directions of the shelf 10.

[0049] For the sake of clarity, in the following explanation, the upper and lower shelf units 20 located on the left side of Figures 4 and 5 will be referred to as the first shelf unit 20L, and the upper and lower shelf units 20 located on the right side of Figures 4 and 5 will be referred to as the second shelf unit 20R. Furthermore, the column members 22 and shelf boards 30 constituting the first shelf unit 20L will be referred to as the first column member 22L and the first shelf board 30L, and the column members 22 and shelf boards 30 constituting the second shelf unit 20R will be referred to as the second column member 22R and the second shelf board 30R.

[0050] Multiple first shelf units 20L are arranged vertically on the shelf 10. In this arrangement, a pair of first column members 22L of multiple first shelf units 20L are arranged to be continuous in the vertical direction. This creates a joint X between the ends of vertically adjacent first column members 22L. Note that the first shelf units 20L are examples of first shelf sections and units.

[0051] Multiple second shelf units 20R are arranged vertically along the shelf 10, next to multiple first shelf units 20L. In this arrangement, a pair of second column members 22R of multiple second shelf units 20R are arranged to be continuous in the vertical direction. This creates a joint X between the ends of vertically adjacent second column members 22R. Note that the second shelf unit 20R is an example of a second shelf section and unit.

[0052] The adjacent first shelf unit 20L and second shelf unit 20R are positioned with the joint surfaces 22A of the first column member 22L and the joint surfaces 22A of the second column member 22R overlapping. In this arrangement, the joint X between the first column members 22L and the joint X between the second column members 22R are offset vertically, and the first shelf board 30L and the second shelf board 30R are positioned at the same height. As a result, the first shelf board 30L and the second shelf board 30R are continuous in the width direction of the shelf 10.

[0053] In this state, the first column member 22L and the second column member 22R are bolted together by multiple countersunk bolts 44. As a result, the first column member 22L and the second column member 22R form the shelf support 12 of the shelf 10.

[0054] Here, by shifting the joint X between the first column members 22L and the joint X between the second column members 22R in the vertical direction, the intermediate portion 22M of the first column member 22L is positioned across the upper extension 22U of the lower second column member 22R and the lower extension 22D of the upper second column member 22R. As a result, the intermediate portion 22M of the first column member 22L reinforces the joint X between the upper and lower second column members 22R. In other words, the intermediate portion 22M of the first column member 22L functions as a reinforcing plate for the joint X between the upper and lower second column members 22R.

[0055] Furthermore, the intermediate portion 22M of the second column member 22R is positioned across the upper extension 22U of the lower first column member 22L and the lower extension 22D of the upper first column member 22L. As a result, the intermediate portion 22M of the second column member 22R reinforces the joint X between the upper and lower first column members 22L. In other words, the intermediate portion 22M of the second column member 22R functions as a reinforcing plate for the joint X between the upper and lower first column members 22L.

[0056] (Fixing structure for the base of the shelf support column) As shown in Figure 6, at the base of the shelf support 12, for example, the first column member 22L of the first shelf unit 20L extends downward below the second column member 22R of the second shelf unit 20R. This creates a step between the first column member 22L and the second column member 22R.

[0057] Therefore, the base of the shelf support 12 is fixed to the slab 70 via a column base unit 50 that absorbs the step difference between the first column member 22L and the second column member 22R. This ensures that the plate thickness of the shelf support 12 is approximately constant. The column base unit 50 has a base plate 52 and a stepped column member 60. Note that the slab 70 is an example of the lower structure.

[0058] (Base plate) The base plate 52 is made of a metal plate such as aluminum or steel. Multiple anchor bolts 72 protruding from the upper surface of the slab 70 are passed through the base plate 52 in the vertical direction. The base plate 52 is fixed to the upper surface of the slab 70 via the multiple anchor bolts 72 by tightening nuts 74 onto these anchor bolts 72.

[0059] Furthermore, a filler material 76, such as mortar or grout, is filled between the base plate 52 and the slab 70.

[0060] (Stepped column material) The stepped column member 60 is formed from a metal plate such as aluminum or steel. This stepped column member 60 has a thick section 62 and a thin section 64. The thick section 62 extends upward from the base plate 52. The thickness of the thick section 62 is, for example, approximately twice the thickness of the first column member 22L and the second column member 22R. The thin section 64 extends upward from the upper end surface of the thick section 62.

[0061] The thickness of the thin-walled section 64 is, for example, approximately half the thickness of the thick-walled section 62. In other words, the thickness of the thin-walled section 64 is approximately the same as the thickness of the first column member 22L and the second column member 22R. This thin-walled section 64 is positioned on the second shelf unit 20R side of the upper end surface of the thick-walled section 62, and the surfaces (sides) of the thin-walled section 64 and the thick-walled section 62 on the second shelf unit 20R side are flush.

[0062] As a result, a step is formed between the thick-walled portion 62 and the thin-walled portion 64 on the first shelf unit 20L side of the stepped column member 60. In addition, a housing portion 66 for housing the first column member 22L is formed on the first shelf unit 20L side of the thin-walled portion 64. Multiple screw holes 40 are formed in this thin-walled portion 64 at intervals in the vertical direction.

[0063] Here, the second column member 22R is positioned to be continuous with the thin-walled portion 64 in the vertical direction. As a result, a joint X is formed between the thin-walled portion 64 and the second column member 22R.

[0064] On the other hand, the first column member 22L, which extends downward from the second column member 22R, is housed in the receiving section 66 of the stepped column member 60. As a result, the first column member 22L is positioned across the thin-walled section 64 and the second column member 22R. In this state, the first column member 22L is bolted to the thin-walled section 64 and the second column member 22R, respectively, using countersunk bolts 44. In this way, the first column member 22L and the second column member 22R are fixed to the slab 70 via the stepped column member 60. Furthermore, the plate thickness of the shelf support 12 is kept approximately constant.

[0065] (Fixing structure for the top of the shelf support post) As shown in Figure 7, at the top of the shelf support column 12, for example, the first column member 22L of the first shelf unit 20L extends upward above the second column member 22R of the second shelf unit 20R. This creates a step between the first column member 22L and the second column member 22R.

[0066] Therefore, the base of the shelf support 12 is fixed to the slab 100 via a column head unit 80 that absorbs the step difference between, for example, the first column member 22L and the second column member 22R. This ensures that the plate thickness of the shelf support 12 is approximately constant. Specifically, the column head unit 80 has a base plate 82 and a stepped column member 90. The slab 100 is an example of the structure shown above.

[0067] (Base plate) The base plate 82 is formed from a metal plate such as aluminum or steel. Multiple anchor bolts 102 protruding from the underside of the slab 100 are passed through the base plate 82 in the vertical direction. The base plate 82 is fixed to the underside of the slab 100 via the multiple anchor bolts 102 by tightening nuts 104 onto these anchor bolts 102.

[0068] Furthermore, a filler material 106, such as mortar or grout, is filled between the base plate 82 and the slab 100.

[0069] The stepped column member 90 is formed from a metal plate such as aluminum or steel. This stepped column member 90 has a thick section 92 and a thin section 94. The thick section 92 extends downward from the base plate 82. The thickness of the thick section 92 is, for example, approximately twice the thickness of the first column member 22L and the second column member 22R. The thin section 94 extends downward from the lower end surface of the thick section 92.

[0070] The thickness of the thin-walled section 94 is, for example, approximately half the thickness of the thick-walled section 92. In other words, the thickness of the thin-walled section 94 is approximately the same as the thickness of the first column member 22L and the second column member 22R. This thin-walled section 94 is positioned on the second shelf unit 20R side of the lower end surface of the thick-walled section 92, and the surfaces (sides) of the thin-walled section 94 and the thick-walled section 92 on the second shelf unit 20R side are flush.

[0071] As a result, a step is formed between the thick-walled portion 92 and the thin-walled portion 94 on the first shelf unit 20L side of the stepped column member 90. In addition, a housing portion 96 for housing the first column member 22L is formed on the first shelf unit 20L side of the thin-walled portion 94. Multiple screw holes 40 are formed in this thin-walled portion 94 at intervals in the vertical direction.

[0072] Here, the second column member 22R is positioned to be continuous with the thin-walled portion 94 in the vertical direction. As a result, a joint X is formed between the thin-walled portion 94 and the second column member 22R.

[0073] On the other hand, the first column member 22L, which extends upward from the second column member 22R, is housed in the receiving section 96 of the stepped column member 90. As a result, the first column member 22L is positioned across the thin-walled section 94 and the second column member 22R. In this state, the first column member 22L is bolted to the thin-walled section 94 and the second column member 22R, respectively, using countersunk bolts 44. In this way, the first column member 22L and the second column member 22R are fixed to the slab 100 via the stepped column member 90. Furthermore, the plate thickness of the shelf support 12 is kept approximately constant.

[0074] In this embodiment, as an example, the first column member 22L and the thin-walled portion 94 are joined by countersunk bolts 44 and nuts 46.

[0075] (action) Next, the operation of this embodiment will be described.

[0076] As shown in Figure 4, according to this embodiment, a plurality of first shelf units 20L are arranged in the vertical direction. In this case, a pair of first column members 22L of the plurality of first shelf units 20L are connected in the vertical direction, and a joint X is formed between the ends of adjacent first column members 22L.

[0077] Multiple second shelf units 20R are arranged next to multiple first shelf units 20L. The multiple second shelf units 20R are arranged vertically. In this arrangement, a pair of second column members 22R of the multiple second shelf units 20R are connected vertically, and a joint X is formed between the ends of adjacent second column members 22R.

[0078] Here, as shown in Figure 5, the adjacent first shelf unit 20L and second shelf unit 20R are joined with the joint X between the first column members 22L and the joint X between the second column members 22R offset in the vertical direction. As a result, the joint X between the first column members 22L is reinforced by the second column member 22R, and the joint X between the second column members 22R is reinforced by the first column member 22L. Therefore, the reduction in strength of the shelf support 12 is suppressed.

[0079] Furthermore, in this embodiment, since it is not necessary to partially reinforce the joints X between the first column members 22L and the joints X between the second column members 22R with splice plates or the like, the partial thickening of the joints X between the first column members 22L and the joints X between the second column members 22R is suppressed.

[0080] Furthermore, by offsetting the joint X between the first column members 22L and the joint X between the second column members 22R in the vertical direction, the joint X between the first column members 22L and the second column members 22R can be reinforced while maintaining a nearly constant thickness for the shelf support 12. Therefore, the aesthetic appeal of the shelf support 12 can be enhanced.

[0081] In this embodiment, the strength of the shelf support 12 can be ensured while the aesthetic design of the shelf support 12 can be enhanced.

[0082] Furthermore, the first shelf unit 20L is a unit that integrates a pair of first column members 22L and a first shelf board 30L. Similarly, the second shelf unit 20R is a unit that integrates a pair of second column members 22R and a second shelf board 30R. This allows the shelf 10 to be easily assembled, for example, by joining the first column members 22L of the first shelf unit 20L and the second column members 22R of the second shelf unit 20R in the installation space for the shelf 10.

[0083] Furthermore, by making the first shelf unit 20L and the second shelf unit 20R into separate units, the assembly time required for the shelf 10 installation space is reduced. In addition, the transportability of the first shelf unit 20L and the second shelf unit 20R is improved. Therefore, the assembly of the shelf 10 is improved.

[0084] Furthermore, the pair of first column members 22L and the first shelf board 30L of the first shelf unit 20L are made of metal plates, and the pair of second column members 22R and the second shelf board 30R of the second shelf unit 20R are also made of metal plates. This makes it possible to make the first column members 22L, the first shelf board 30L, the second column members 22R, and the second shelf board 30R thinner while ensuring strength.

[0085] Furthermore, the pair of first column members 22L and the first shelf board 30L of the first shelf unit 20L are integrated by welding. As a result, in this embodiment, the joint between the pair of first column members 22L and the first shelf board 30L can be simplified compared to the case where the pair of first column members 22L and the first shelf board 30L are bolted together.

[0086] Similarly, the pair of second column members 22R and second shelf boards 30R of the second shelf unit 20R are integrated by welding. This simplifies the joint between the pair of second column members 22R and second shelf boards 30R compared to the case where the pair of second column members 22R and second shelf boards 30R are bolted together.

[0087] In this embodiment, the structure of the shelf 10 can be simplified while ensuring strength. Furthermore, by allowing the shelf board 30 to protrude forward and backward from the shelf support 12, the aesthetic design of the shelf 10 can be enhanced.

[0088] Furthermore, as shown in Figure 6, the base of the shelf support 12 is fixed to the slab 70. Also, as shown in Figure 7, the top of the shelf support 12 is fixed to the slab 100. This suppresses the tipping of the shelf 10 during an earthquake. In addition, in this embodiment, the degree of freedom in the installation location of the shelf 10 is improved compared to when the shelf 10 is fixed to a wall or the like.

[0089] Furthermore, as shown in Figure 6, the base of the shelf support 12 is fixed to the slab 70 via the base unit 50. This allows the shelf support 12 to be easily fixed to the slab 70 while maintaining a substantially constant thickness of the base of the shelf support 12.

[0090] Similarly, as shown in Figure 7, the column heads of the shelf supports 12 are fixed to the slab 100 via the column head units 80. This allows the shelf supports 12 to be easily fixed to the slab 100 while maintaining a substantially constant thickness at the column heads of the shelf supports 12.

[0091] (modified version) Next, a modified example of the above embodiment will be described.

[0092] In the above embodiment, multiple shelf units 20 (first shelf unit 20L and second shelf unit 20R) have the same configuration. However, the configuration of the multiple shelf units 20 can be changed as appropriate.

[0093] For example, in the modified example shown in Figure 8, the shelf board 30 of the shelf unit 20 located in the center of the shelf 10 has one shelf, while the shelf boards 30 of the other shelf units 20 have two shelves. In this way, it is also possible to form the shelf 10 by combining multiple shelf units 20 with different numbers of shelf boards 30.

[0094] Furthermore, in the modified example shown in Figure 9, the first shelf board 30L of the first shelf unit 110L and the second shelf board 30R of the second shelf unit 110R are each made up of a single layer. The first shelf board 30L is installed in the vertical center of a pair of first column members 22L. Similarly, the second shelf board 30R is installed in the vertical center of a pair of second column members 22R.

[0095] The adjacent first shelf unit 110L and second shelf unit 110R are positioned with the joint surface 22A of the first column member 22L and the joint surface 22A of the second column member 22R overlapping. In this arrangement, the joint X between the first column members 22L and the joint X between the second column members 22R are offset vertically. As a result, the joint X between the first column members 22L is reinforced by the second column member 22R, and the joint X between the second column members 22R is reinforced by the first column member 22L.

[0096] Furthermore, in this modified example, the first shelf board 30L and the second shelf board 30R are positioned at different heights. Thus, it is also possible to position the first shelf board 30L and the second shelf board 30R at different heights. Note that the first shelf unit 110L is an example of the first shelf section and unit. Similarly, the second shelf unit 110R is an example of the second shelf section and unit.

[0097] Although not shown in the diagram, the shelf unit may have three or more shelves.

[0098] Furthermore, in the above embodiment, the shelf unit 20 has a pair of column members 22. However, the shelf unit 20 only needs to have at least two column members 22, and may have, for example, three or more column members.

[0099] Furthermore, in the above embodiment, the column members 22 of adjacent shelf units 20 are bolted together. However, the column members 22 of adjacent shelf units 20 may be joined not only by bolts, but also by screws, adhesive, or the like.

[0100] In the above embodiment, the pair of column members 22 and the shelf board 30 of the shelf unit 20 are welded together. However, the pair of column members 22 and the shelf board 30 may be joined together by adhesive, bolts, or the like.

[0101] Furthermore, in the above embodiment, the base of the shelf support 12 is fixed to the slab 70 via the base unit 50. However, the fixing structure of the shelf support 12 to the slab 70 can be changed as appropriate. Similarly, in the above embodiment, the top of the shelf support 12 is fixed to the slab 100 via the top unit 80. However, the fixing structure of the shelf support 12 to the slab 100 can be changed as appropriate.

[0102] Furthermore, the shelf support 12 may be fixed not only to the slab 70, 100, but also to the structural frame such as beams or foundations. The shelf support 12 may also be fixed to walls, etc.

[0103] Furthermore, in the above embodiment, the column member 22 and the shelf board 30 are integrated into a single unit. However, the pair of column members 22 and the shelf board 30 may be separate and joined together, for example, in the installation space of the shelf 10. Note that the first shelf section in the above embodiment is a concept that includes both the unitized pair of column members 22 and shelf board 30 and the pair of column members 22 and shelf board 30 that are not unitized.

[0104] Furthermore, in the above embodiment, the shelf unit 20 is made of metal. However, the shelf unit 20 may also be made of, for example, resin or wood.

[0105] Although one embodiment of the present invention has been described above, the present invention is not limited to these embodiments, and various modifications may be used in appropriate combinations with one embodiment, and of course, the invention can be implemented in various forms without departing from the spirit of the present invention.
