Description

[Technical field]

[0001] The present invention relates to an automated warehouse. [Background technology]

[0002] There are known automated warehouses that are integrated into buildings. For example, in the structure described in Patent Document 1, in order to improve the fire resistance of the automated warehouse (building), column members made of steel are covered with fire-resistant material such as rock wool. The fire-resistant material is provided on the entire portion of the column member that protrudes inward from the wall. Furthermore, the fire-resistant material is covered with a protective material, thereby maintaining a predetermined fire resistance of the building. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Registration Publication No. 2534181 Summary of the Invention [Problem to be solved by the invention]

[0004] In an automated warehouse integrated with a building, the exterior walls of the building are supported by column members made of steel pipes. However, since the steel pipes are made of thin iron plates, they have poor fire resistance. Fire-resistant coatings such as rock wool as described above can contribute to improving or maintaining fire resistance. However, racks are formed inside the building. If the fire-resistant coating extends into storage space within the automated warehouse that should be effectively used, it may result in a decrease in storage efficiency.

[0005] The present disclosure provides an automated warehouse that can reduce the impact of fire-resistant structure on storage efficiency while ensuring fire resistance performance. [Means for solving the problem]

[0006] [1] One aspect of the present disclosure is an automated warehouse integrated into a building, comprising a rack having a plurality of rack columns extending in a vertical direction, and an outer wall supported by the outermost rack column of the plurality of rack columns, wherein the outer wall extends in a vertical direction and a first horizontal direction, the outermost rack column is connected to the outer wall by a connecting member extending in a second horizontal direction perpendicular to the first horizontal direction and is spaced apart from the outer wall in the second horizontal direction, and at least one non-combustible member made of a non-combustible metallic material extending in the vertical direction is provided in the space between the outer wall and the outermost rack column.

[0007] According to the automated warehouse in [1], the outermost rack column is connected to the outer wall by a connecting member, and a space is formed between the outer wall and the outermost rack column. A non-combustible member made of a non-combustible material is provided in this space, so that the member related to improving the fire resistance performance does not erode the storage space inside the rack. Therefore, the impact of the fire-resistant structure on storage efficiency can be reduced while ensuring fire resistance.

[0008] [2] In the automated warehouse of [1] above, the outer wall may have a plurality of wall materials arranged in a first horizontal direction and joints formed between the plurality of wall materials, and the non-combustible member may be arranged in a space between the joints and the outermost rack column. Fire resistance is particularly required in the joints. With this configuration, fire resistance in the joints can be sufficiently ensured.

[0009] [3] In the automated warehouse according to [1] or [2] above, the noncombustible members may be formed in a hollow rectangular shape in horizontal cross section. With this configuration, it is possible to prevent the noncombustible members from being deformed by heat.

[0010] [4] In the automated warehouse according to [1] or [2] above, the noncombustible members may have a cross-sectional shape that is open in either one of the second horizontal directions. This configuration can prevent the noncombustible members from being deformed by heat, and can also reduce their weight.

[0011] [5] In the automated warehouse according to [1] or [2] above, the noncombustible member may be at least one plate-shaped member having a thickness in the second horizontal direction. With this configuration, fire resistance can be ensured with a simple configuration. Effect of the Invention

[0012] According to the present disclosure, it is possible to reduce the impact of the fire-resistant structure on storage efficiency while ensuring fire resistance performance. [Brief description of the drawings]

[0014] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the description of the drawings, the same elements are given the same reference numerals, and duplicated description will be omitted. For convenience of description, XYZ orthogonal axes are also shown in the drawings. In the following description, the Z direction corresponds to the up-down direction (vertical direction), either the X direction or the Y direction corresponds to the first horizontal direction, and the other of the X direction and the Y direction corresponds to the second horizontal direction.

[0015] The overall configuration of the automated warehouse 1 will be described with reference to FIG. 1. The automated warehouse 1 is an integrated type automated warehouse. In the automated warehouse 1, a rack 2 and a building B are integrally constructed on a foundation A. The automated warehouse 1 includes a rack 2 having a plurality of rack columns 10 erected on the foundation A and extending in the Z direction, and a plurality of horizontal members 4 bridged between the rack columns 10. The automated warehouse 1 includes a pair of racks 2 facing each other in the Y direction (direction perpendicular to the paper surface of FIG. 1), for example. A plurality of storage shelves are formed in each rack 2, and luggage (items) are stored in the storage shelves. The automated warehouse 1 includes a stacker crane 3 that can move in the X direction along rails 3a in the space between the pair of racks 2. The stacker crane 3 includes a mast 3b that extends in the Z direction, and a transfer device 3c that can rise and fall along the mast 3b and transfer luggage (items) between the racks 2. The automated warehouse 1 may include only a pair of racks 2, or may include multiple pairs of racks 2.

[0016] Among the multiple rack columns 10, multiple outermost rack columns 12 are arranged on the outermost sides (closest to the outer wall 5) in the X and Y directions. These outermost rack columns 12 support the outer wall 5 of the automated warehouse 1. When the building B has a rectangular parallelepiped shape as a whole, a pair of outer walls 5 arranged at both ends in the X direction extend in the Z and Y directions. A pair of outer walls 5 arranged at both ends in the Y direction extend in the Z and X directions. Depending on the shape, number, and arrangement of the racks 2, the building B may have a three-dimensional shape other than a simple rectangular parallelepiped shape. In any case, the outer wall 5 is arranged in a planar shape along a vertical plane. The upper end surface of the rack 2 supports the roof 6 of the building B. A loading / unloading station is provided at least at one location of the building B.

[0017] The fireproof structure of the automated warehouse 1 of this embodiment will be described with reference to Figs. 2 and 3. Figs. 2 and 3 will describe a fireproof structure according to a first configuration example provided on the inner side of the outer wall 5 extending in the Z direction and the X direction. The fireproof structure of the outer wall 5 extending in the Z direction and the Y direction, which constitutes another outer wall surface from this outer wall 5, has the same configuration, so description and illustration will be omitted. The outermost rack column 12 is made of, for example, a hollow rectangular columnar steel material. The outer wall 5 has a plurality of wall materials 5a arranged side by side in the X direction and the Z direction. Each wall material 5a is a rectangular plate-shaped member made of, for example, lightweight aerated concrete. In the outer wall 5, a joint portion 5c is formed between the plurality of wall materials 5a, 5a arranged side by side in the X direction (see Fig. 2). In the X direction, the outermost rack column 12 is provided at the position of the joint portion 5c, which is the mating surface of the two wall materials 5a.

[0018] As shown in Fig. 2 and Fig. 3, the outermost rack column 12 supports the outer wall 5 consisting of a plurality of wall materials 5a from the inner side via the support part 20. The support part 20 includes a base member 21 made of, for example, an angle iron (angle bar) and extending in the Z direction, a pressing member 22 that presses one plate part of the base member 21 against the inner wall surface 5b of the outer wall 5, and a fixing member 23 that fixes the pressing member 22. The base member 21, the pressing member 22, and the fixing member 23 are provided on both sides of the outermost rack column 12 in the X direction so as to sandwich both side surfaces 12a of the outermost rack column 12 in the X direction. The pressing member 22 extends in the Z direction, and the fixing members 23 are provided at a plurality of appropriate positions in the Z direction. Each fixing member 23 is, for example, a fastening member including a bolt screwed (or erected) into the wall material 5a and a nut.

[0019] The support portion 20 includes a rectangular connecting member 25 made of a steel plate or the like. The outermost rack column 12 is connected to the outer wall 5 via the base member 21 by the connecting member 25 extending in the Y direction. A pair of parallel connecting members 25 are provided, for example, between the pair of base members 21 and are provided so as to sandwich a pair of side surfaces 12a of the outermost rack column 12. First ends (outer ends close to the outer wall 5) of the pair of connecting members 25 in the Y direction are abutted against the inner surface of the base member 21 and fixed by welding or the like. Second ends (inner ends far from the outer wall 5) of the pair of connecting members 25 in the Y direction are abutted against the side surface 12a of the outermost rack column 12 and fixed by welding or the like. The connecting members 25 are provided at appropriate multiple locations in the Z direction.

[0020] The support part 20 is assembled at the construction site of the building B including the rack 2. However, some or all of the base member 21, the pressing member 22, and the connecting member 25 may be integrated by welding, screw fastening, or the like in a factory and fabricated in advance as a support unit, and the support unit may be transported to the construction site and assembled. Some or all of the base member 21, the pressing member 22, and the connecting member 25 may be integrally molded steel members.

[0021] The outermost rack pillar 12 is spaced from the inner wall surface 5b of the outer wall 5 in the Y direction. A rectangular prism-shaped space S extending in the Z direction is formed between the outer wall 5 and the outermost rack pillar 12. This space S is defined in the Y direction by the inner wall surface 5b of the outer wall 5 and the outer side surface 12c of the outermost rack pillar 12. The space S is defined in the X direction by the other plate portion of the base member 21 (the plate portion perpendicular to the inner wall surface 5b). At the height position where the connecting members 25 are provided, the space S is defined by the pair of connecting members 25.

[0022] In the space S between the exterior wall 5 and one of the outermost rack columns 12, one noncombustible member 30 made of a metallic noncombustible material is disposed. The noncombustible member 30 is disposed so as to extend in the Z direction. Examples of the noncombustible material include steel, aluminum, and other metals. Based on the Building Standards Act, the noncombustible material is one that satisfies the following three requirements when exposed to the heat of a normal fire: (i) Not combustible (ii) There is no risk of fire-related damage (deformation, welding, cracks, etc.) (iii) Not generating smoke or gases that are harmful to evacuation Assuming that these three requirements can basically be met, materials are classified into "noncombustible materials" (20 minutes after heating starts), "semi-noncombustible materials" (10 minutes after heating starts), and "flame-retardant materials" (5 minutes after heating starts) depending on the length of heating time during which the three requirements can be maintained (until they are no longer met). In the automated warehouse 1 of this embodiment, for example, "noncombustible materials" (20 minutes after heating starts) is selected.

[0023] As shown in FIG. 2, the noncombustible member 30 is disposed in the space S between the joint 5c of the outer wall 5 and the outermost rack column 12. For example, a channel steel is used as the noncombustible member 30. The noncombustible member 30 includes a pair of parallel side portions 30a spaced apart in the X direction, an inner side portion 30b facing the outer side surface 12c of the outermost rack column 12, and an outer side portion 30c facing the inner wall surface 5b of the outer wall 5. The center of the outer side portion 30c is open. In this way, the noncombustible member 30 is installed so that the open portion faces the joint 5c (outward). The thickness of each side portion may be determined appropriately, but is, for example, 1 mm or more.

[0024] The noncombustible member 30 is disposed close to the outer wall 5. The outer surface portion 30c of the noncombustible member 30 is in contact with, for example, the inner wall surface 5b of the outer wall 5, and the inner surface portion 30b is spaced apart from, for example, the outer surface 12c of the outermost rack column 12. With this arrangement, the noncombustible member 30 does not protrude from the base member 21 when viewed from the X direction, and is contained within the range of the base member 21 (see FIG. 3). The noncombustible member 30 is an unnecessary member structurally in the automated warehouse 1, and is provided only to ensure fire resistance. The noncombustible member 30 may be connected to any surrounding member, but is welded to the inner surface of a pair of connecting members 25, for example.

[0025] In the automated warehouse 1, no fire-resistant covering such as rock wool is provided on the outermost rack columns 12. Fire resistance is ensured by the noncombustible members 30.

[0026] According to the automated warehouse 1 of the present embodiment described above, the outermost rack column 12 is connected to the outer wall 5 by the connecting member 25, and a space S is formed between the outer wall 5 and the outermost rack column 12. Since the non-combustible member 30 made of a non-combustible material is provided in this space S, the member related to the improvement of the fire resistance performance does not erode the storage space in the rack 2. Therefore, the impact of the fire-resistant structure on the storage efficiency can be reduced while ensuring the fire resistance. In addition, when applying the conventional fire-resistant coating, it was necessary to wrap the fire-resistant material around the inner side of the outermost rack column, which made the application difficult. However, according to the configuration of the present disclosure, application on the outer side of the outermost rack column 12 is possible, and application is also improved.

[0027] Fire resistance is particularly required at the joints 5c of the exterior wall 5. With this configuration, it is possible to ensure sufficient fire resistance at the joints 5c.

[0028] Furthermore, the noncombustible member 30 has a cross-sectional shape that is open on one side in the Y direction (the outer surface side), which not only prevents the noncombustible member 30 from being deformed by heat, but also makes it possible to further reduce the weight.

[0029] Next, a fireproof structure according to a second configuration example will be described with reference to Figs. 4 and 5. As shown in Figs. 4 and 5, the fireproof structure according to the second configuration example is different from the fireproof structure according to the first configuration example (Figs. 2 and 3) in that a noncombustible member 30A extending in the Z direction and having a rectangular closed cross section is provided instead of the noncombustible member 30 made of channel steel. The noncombustible member 30A is formed in a hollow rectangular shape in the horizontal cross section. The noncombustible member 30A is also made of the same noncombustible material as the noncombustible member 30. A hollow rectangular columnar steel material is used as the noncombustible member 30A. The thickness of each side portion may be determined appropriately, but is set to, for example, 1 mm or more.

[0030] The noncombustible member 30A is disposed close to the outer wall 5. The outer surface portion 30c of the noncombustible member 30A abuts against, for example, the inner wall surface 5b of the outer wall 5, and the inner surface portion 30b is slightly spaced from, for example, the outer surface 12c of the outermost rack column 12. The noncombustible member 30A protrudes from the base member 21 when viewed from the X direction (see FIG. 5). The noncombustible member 30 is a member that is not structurally necessary for the automated warehouse 1, and is provided only to ensure fire resistance. The noncombustible member 30 may be connected to any surrounding member, but is welded to the inner surface of a pair of connecting members 25, for example. The noncombustible member 30A may not protrude from the base member 21 when viewed from the X direction, and may be within the range of the base member 21.

[0031] The automated warehouse 1 including the noncombustible members 30A also provides the same functions and effects as those of the first configuration example.

[0032] The noncombustible member 30 is formed in a hollow rectangular shape in horizontal cross section, which makes it possible to prevent the noncombustible member from being deformed by heat.

[0033] The noncombustible member 30A has a rectangular annular closed cross section. This prevents the noncombustible member 30A from being deformed by heat, and improves fire resistance. In the noncombustible member 30A, two steel plates, an inner side surface portion 30b and an outer side surface portion 30c, are present between the inner wall surface 5b of the outer wall 5 and the outer side surface 12c of the outermost rack column 12.

[0034] Next, referring to Fig. 6 and Fig. 7, fireproof structures according to the third and fourth configuration examples will be described. In the fireproof structure according to the third configuration example shown in Fig. 6, a noncombustible member 30B consisting of three plate-shaped members 31, 32, and 33 extending in the Z direction is arranged in the space S between the joint 5c of the outer wall 5 and the outermost rack column 12. These plate-shaped members 31, 32, and 33 have a thickness in the Y direction. The thickness of each plate-shaped member may be appropriately determined, but is, for example, 1 mm or more. The three plate-shaped members 31, 32, and 33 are arranged overlappingly with a slight interval (gap) in the Y direction. Each of the plate-shaped members 31, 32, and 33 is attached to the inner surface of the connection member 25 by welding or the like. In the noncombustible member 30B, three steel plates are present between the inner wall surface 5b of the outer wall 5 and the outer surface 12c of the outermost rack column 12.

[0035] The automated warehouse 1 including the noncombustible members 30B also achieves the same effects and advantages as the first and second configuration examples. Moreover, fire resistance can be ensured with a simple configuration.

[0036] In the fireproof structure according to the fourth configuration example shown in Fig. 7, a non-combustible member 30C consisting of only one plate-shaped member 31 extending in the Z direction is disposed in the space S between the joint 5c of the outer wall 5 and the outermost rack column 12. The automated warehouse 1 equipped with such a non-combustible member 30C also achieves the same effects and advantages as the first and second configuration examples. Moreover, fireproof performance can be ensured with a simple configuration.

[0037] Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment. For example, the support part 20 is not limited to a form including a pair of connecting members 25 at a certain height position, and may include only one connecting member 25. The connecting member is not limited to a plate-like member as in the above embodiment. It may be a rod-like member or a column-like member, or may have other known shapes (shapes known as connecting fittings). A fire-resistant structure including the outermost rack column 12 and the noncombustible member 30, etc. may be provided at a position other than the joint part 5c. [Explanation of symbols]
