Description

The present invention relates to racks for automated warehouses, and in particular to racks for automated warehouses that are integrated into structures.

Conventionally, automated warehouse racks equipped with support columns, beams, braces, etc. are known. Among such automated warehouse racks, there is known a so-called "building-integrated building-type rack" (structure-integrated automated warehouse) in which the multiple support columns serve as structural columns of the building, and the exterior walls, roof, etc. are integrated into the automated warehouse (see, for example, Patent Document 1).

Japanese Patent Application Publication No. 11-165819

In an automated warehouse that employs the above-mentioned "architecturally integrated building-style rack," if a fire breaks out either inside or outside the warehouse, it is necessary to prevent the warehouse from collapsing and to limit the spread of the fire. Therefore, in order to protect the columns (structural columns) of the automated warehouse from fire, fire-resistant coating has traditionally been provided on at least the outer periphery of the columns supporting the warehouse's exterior walls. Such fire-resistant coating has traditionally been applied by wrapping a 40 mm thick fire-resistant coating material, such as heat-resistant rock wool, around the columns.

However, this type of fire-resistant coating is generally installed after the steel frame structure of the automated warehouse has been assembled, and requires workers to climb to high places by hand to wrap the fire-resistant coating around the supports and secure them with welding pins, etc., making it a dangerous job that also requires scaffolding. For this reason, there is a demand to reduce the workload by making the fire-resistant coating as thin as possible, or even to eliminate the fire-resistant coating altogether.

The present invention was conceived to solve the above-mentioned problems, and aims to provide a rack for an automated warehouse that is integrated into a structure, which can prevent the collapse of the exterior wall and the resulting collapse of the automated warehouse in the event of a fire, while reducing the thickness of the fire-resistant coating provided on the support pillars to which the exterior wall is attached, or eliminating it altogether.

To achieve the above objective, the present invention provides a rack for an integrated structure automated warehouse, comprising a plurality of support columns, a plurality of connecting members connecting the plurality of support columns to one another, a plurality of shelf support members attached to the plurality of support columns, and an outer wall supported by the plurality of support columns, wherein the plurality of connecting members include diagonal members that connect the plurality of support columns diagonally to form a truss structure, and the plurality of support columns include a first support column comprising an outer steel pipe, an inner steel pipe, and a filler material filled between the outer steel pipe and the inner steel pipe, and a second support column comprising a steel pipe, and the outer wall is supported by the first of the plurality of support columns.

According to the present invention, a rack for an automated warehouse integrated with a structure includes multiple support columns, multiple connecting members connecting the multiple support columns to each other, multiple shelf support members attached to the multiple support columns, and an outer wall supported by the multiple support columns. The multiple connecting members include multiple diagonal members connecting the multiple support columns diagonally to form a truss structure, thereby forming a rack for an automated warehouse integrated with a structure having a truss structure. In such an automated warehouse rack, the multiple support columns include a first support column comprising an outer steel pipe, an inner steel pipe, and a filler material therebetween, and the outer wall is supported by the first support column. Therefore, in the first support column that supports the outer wall and requires fire resistance, the outer steel pipe supports the normal load. In the event of a fire outside or inside the automated warehouse, the strength of the inner steel pipe prevents the first support column from buckling, thereby preventing the collapse of the outer wall. As a result, the thickness of the fire-resistant coating on the support pillars (first support pillars) to which the exterior walls are attached can be reduced compared to conventional methods, or even eliminated altogether, while still preventing the collapse of the exterior walls and the resulting collapse of the automated warehouse in the event of a fire.

In the present invention, preferably, the diagonal members connect the first support columns and the second support columns to form a truss structure, and the exterior wall is supported by the first support columns that form the truss structure.
According to the present invention configured in this manner, in the event of a fire, it is possible to more effectively prevent the collapse of the outer walls of an automated warehouse having a truss structure.

In addition, in the present invention, preferably, the diagonal members connect the second supports to form a truss structure, the first supports are attached to the second supports of this truss structure as support columns, and the exterior wall is supported by the first supports as support columns.
According to the present invention configured in this manner, even in an automated warehouse where the exterior walls are supported by truss-structured support columns, the collapse of the exterior walls can be more effectively prevented in the event of a fire.

In addition, in the present invention, preferably, the outer steel pipe of the first support pillar is a steel pipe having a rectangular cross section, the inner steel pipe of the first support pillar is a steel pipe having a circular cross section, and the filler material of the first support pillar is a concrete material.
According to the present invention configured as described above, the outer steel pipe of the first support column is a steel pipe with a rectangular cross section, so it can effectively support long-term loads (static loads) under normal conditions and short-term loads (dynamic loads) during earthquakes. Furthermore, the inner steel pipe of the first support column is a steel pipe with a circular cross section, so its buckling prevention effect can improve the buckling resistance of the outer steel pipe. Furthermore, because the inner steel pipe is a steel pipe with a circular cross section and the filler is concrete, a sufficient distance can be secured between the inner and outer steel pipes, effectively utilizing the heat absorption effect of the concrete material.

In the present invention, preferably, the inner steel pipe of the first support column has a plurality of dowel bars welded to its outer circumferential surface.
According to the present invention configured in this manner, the shear strength of the first support column can be increased by the multiple dowel reinforcements, thereby increasing the buckling resistance of the first support column.

In addition, in the present invention, preferably, the outer steel pipe of the first support is a steel pipe with a rectangular cross section, the inner steel pipe of the first support is a steel pipe with a circular cross section, the filler material of the first support is a concrete material, and the multiple dowel reinforcement bars are arranged in the outer steel pipe so as to extend diagonally to the four corners of the outer steel pipe with a rectangular cross section, and are integrated with the concrete material, which is the filler material filled between the outer steel pipe and the inner steel pipe.
According to the present invention configured as described above, the multiple dowel reinforcements are provided inside the outer steel pipe so as to extend diagonally from the four corners of the rectangular cross-section outer steel pipe. This allows the center of the inner steel pipe to be determined (centered) when the inner steel pipe is installed inside the outer steel pipe. In particular, the closer the dimensions of the dowel reinforcement are to the diagonal inner dimensions of the outer steel pipe, the more reliable the centering can be. Furthermore, because the dowel reinforcement is integrated with the concrete material, the shear strength of the first support can be more effectively increased.

In the present invention, the inside of the inner steel pipe of the first support is preferably filled with a heat absorbing material.
According to the present invention configured in this manner, the fire resistance performance of the first support column can be further improved.

In addition, in the present invention, it is preferable that a shelf support member is welded and fixed to the outer peripheral surface of the outer steel pipe of the first support, and the filler material between the outer steel pipe and the inner steel pipe is filled after the shelf support member is welded and fixed.
According to the present invention configured in this manner, the shelf support members of an automated warehouse can be made to have a simple shape, and the shelf support members can be reliably welded and fixed in place without heat being lost by the filler material.

The structure-integrated automated warehouse rack of the present invention reduces the thickness of the fire-resistant coating on the support pillars to which the exterior walls are attached, or even eliminates it, while preventing the collapse of the exterior walls and the resulting collapse of the automated warehouse in the event of a fire.

Next, with reference to the attached drawings, we will explain the racking of an automated warehouse with an integrated structure according to an embodiment of the present invention.

First, the schematic configuration of a rack in a structure-integrated automated warehouse according to an embodiment of the present invention will be described with reference to Figures 1 and 2. Figure 1 is a front view showing the schematic configuration of a rack in a structure-integrated automated warehouse according to an embodiment of the present invention, and Figure 2 is a side view showing the schematic configuration of a rack in a structure-integrated automated warehouse according to an embodiment of the present invention.
1 and 2, the rack 2 of the structure-integrated automated warehouse 1 according to an embodiment of the present invention is a so-called "architecturally integrated building-type rack" constructed on a foundation B on the ground G. As shown in FIG. 1, the rack 2 according to this embodiment includes a plurality of rows of rack assemblies 4 arranged in the front-to-rear direction, a stacker crane 6 and its aisle 8 provided between a pair of rack assemblies 4, an outer wall 10 supported by first support columns 14 according to this embodiment or first support columns 15 according to a modified example, which will be described later, of the rack assemblies 4, and a roof 12.

Next, the schematic configuration of the rack 2 according to this embodiment will be described with reference to Figures 3 and 4. Figure 3 is a perspective view of a rack unit provided in a rack of a structure-integrated automated warehouse according to this embodiment, as viewed from the outer wall side, and Figure 4 is a perspective view of the rack unit of this embodiment shown in Figure 3, as viewed from the crane aisle side.
First, as shown in FIGS. 3 and 4 , the rack 2 includes first support columns ("first support columns") 14 (two columns in the rack unit 16 shown in each figure) having a double-tube structure (concrete-filled steel tube structure, CFT (Concrete Filled Steel Tube)) described below, and second support columns ("second support columns") 18 (four columns in the rack unit 16 shown in each figure) made of square-section steel pipes. Unlike the first support columns 14, the second support columns 18 do not have a double-tube structure, and the interior of the steel pipe is hollow and not filled with concrete or other filler. Here, assuming that the aisle 8 side is the front side and the exterior wall 10 side is the rear side, the rack 2 includes three front second support columns 18a, one rear second support column 18b, and two rear first support columns 14b.

Of these supports, on both the left and right sides of the rack unit 16 shown in Figures 3 and 4, a front second support 18a and a rear first support 14b are arranged in the front-to-rear direction, and a multi-tiered load-receiving shelf section ("shelf support member") 20 is fixed by welding.Furthermore, in the left-to-right center of the rack unit 16, a multi-tiered load-receiving shelf section ("shelf support member") 20 is fixed by welding to a front second support 18a and a rear second support 18b are arranged in the front-to-rear direction.

3 and 4, the front second support columns 18a and the rear first support columns 14b are connected to each other on both the left and right sides by a plurality of diagonal members 22 and connecting members 24 that extend in the front-to-rear and horizontal directions. By connecting in this manner, the front second support columns 18a, the rear first support columns 14b, the diagonal members 22, and the connecting members 24 are provided as members that constitute a truss structure.
On the other hand, the front second support pillar 18a and the rear second support pillar 18b, which are located in the center in the left-right direction, are connected to each other by a connecting member 24 that extends in the front-rear direction and horizontally, as shown in the drawing.

Thus, the rack 2 of this embodiment has a first frame unit in which the first support 14b and the second support 18a are connected by a diagonal member 22 and a connecting member 24, and a cargo receiving shelf section 20 is provided, and a second frame unit in which the second support 18a, 18b are connected by a connecting member 24 and a cargo receiving shelf section 20, and a cargo receiving shelf section 20 is provided, and these first frame units and second frame units are arranged alternately in the left-right direction (see Figure 2) to form a rack unit 16.
On the front side of the rack unit 16, multiple second pillars 18a (all of which are second pillars 18a) are arranged along the left-right direction, and on the rear side of the rack unit 16, first pillars 14b and second pillars 18b are arranged alternately along the left-right direction.
3 and 4 show a part of such a rack unit 16, showing two first frame units and one second frame unit provided therebetween.

The rack unit 16 shown in Figures 3 and 4 has two rows of storage shelves in the left-right direction and three tiers in the up-down direction. As shown in Figures 3 and 4, the columns 14b, 18a, 18b arranged along the front-to-rear direction are connected (assembled) to each other by the front horizontal member 26a, the rear horizontal member 26b, the flat brace 28, and the rear brace 30 to form the rack assembly 4.

In the figure, reference numeral 32 denotes mounting members for attaching each end of the planar brace 28 and each end of the horizontal members 26a, 26b to each support column 14, 18 using fastening members, and reference numeral 34 denotes mounting members for attaching each end of the rear brace 30 to each support column 14, 18 using fastening members.

Next, as described above, the automated warehouse 1 of this embodiment is an "architecturally integrated building-type rack," and each of the support columns 14, 18 serves as its structural column. Furthermore, each of the support columns 14, 18, which are structural columns, has buckling resistance that allows it to withstand long-term loads (static loads) during normal use in the automated warehouse 1 and short-term loads (dynamic loads) during earthquakes.

In this embodiment, the first support 14 is configured to support the exterior wall 10 (see Figure 1), and the first support 14 and the mounting member 34 are provided with a mating portion (exterior wall fixing portion) 36 consisting of a pair of flat plates for attaching the exterior wall 10 to the first support 14.

Next, the fireproof structure of the rack 2 of the structure-integrated automated warehouse 1 according to an embodiment of the present invention and its modified examples will be described with reference to Figures 3 to 7. Figure 5 is a partial cross-sectional perspective view showing the schematic configuration of a first support pillar provided on the rack of the structure-integrated automated warehouse according to this embodiment, Figure 6 is a cross-sectional view showing a transverse section of the first support pillar of this embodiment shown in Figure 5, and Figure 7 is a cross-sectional view showing a transverse section of the first support pillar according to a modified example of this embodiment, shown similarly to Figure 6.
First, in this embodiment, as described above, the exterior wall 10 is attached to the joint 36 of the first support column 14, and the exterior wall 10 is supported by the first support column 14. The exterior wall 10 is made of a fire-resistant material. In this embodiment, this fire-resistant material is an ALC board.

5 and 6, the first support column 14 of this embodiment comprises an outer steel pipe 40 with a square cross section and an inner steel pipe 42 with a circular cross section that is inserted inside the outer steel pipe 40 and extends in the same vertical direction as the outer steel pipe 40, and a concrete material serving as a filler 44 is filled between the outer steel pipe 40 and the inner steel pipe 42. The inner steel pipe 42 is fixed to the outer steel pipe 40 via this concrete material. In this embodiment, the outer steel pipe 40 has the same shape and dimensions as the square cross section steel pipe of the second support column 18 described above.
In this specification, the term "concrete material" includes so-called concrete (a material mainly made by mixing cement, water, sand, and gravel) and so-called mortar (a material mainly made by mixing cement, water, and sand), but in this embodiment, concrete is used as the filler 44.

Furthermore, a plurality of dowel lines 46 are fixed by welding to the outer circumferential surface of the inner steel pipe 42. Here, for ease of explanation, the cross-sectional view of Fig. 6 shows only the dowel lines 46 as viewed from above. As shown in Fig. 6, the four dowel lines 46 are provided so as to extend on the diagonals of the square cross section from the outer circumferential surface of the inner steel pipe 42 toward the four corners of the outer steel pipe 40 as viewed from above.
In this embodiment, in top view, the dimension of these dowel lines 46 in the direction extending radially from the outer circumferential surface of the inner steel pipe 42 is matched to the diagonal inner dimension of the outer steel pipe 40 (the inner dimension from the outer circumferential surface of the inner steel pipe 42 to the corners of the outer steel pipe 40), thereby making it possible to position (center) the inner steel pipe 42 at the center position of the outer steel pipe 40. Note that the radial dimension of the dowel lines 46 described above is longer than the inner dimension between opposite sides of each side (four sides) of the outer steel pipe 40, but shorter than the diagonal inner dimension of the outer steel pipe 40.
The dowel reinforcement 46 is integrated with the filler material 44, which is concrete, thereby increasing the shear strength of the first support column 14. In other words, the dowel reinforcement 46 is hardened while embedded in the concrete, thereby increasing the shear strength of the first support column 14.

Next, in this embodiment, as shown in Figure 5, to enhance fire resistance, a fire-resistant coating material 48 is wrapped around the outer surface of the outer steel pipe 40, and this wrapped fire-resistant coating material 48 is fixed to the outer steel pipe 40 with a welding pin 50. Note that this fire-resistant coating material 48 is not shown in Figure 6 and Figure 7, which will be described later.

Here, if only the outer steel pipe 40 is provided without the inner steel pipe 42 and filler material 44, a fire-resistant coating material 48 with a thickness of, for example, approximately 40 mm is required to ensure fire resistance. In contrast, in this embodiment, the inner steel pipe 42 and filler material 44 are provided within the outer steel pipe 40 to improve fire resistance and the buckling resistance of the support column, so the thickness of the fire-resistant coating material 48 can be reduced to approximately 10 to 20 mm. Note that if the size of the outer steel pipe 40 and the thickness of the filler material 44 (the distance in cross section between the outer surface of the inner steel pipe 42 and the inner surface of the outer steel pipe 40) are sufficiently large to ensure sufficient fire resistance, the fire-resistant coating material 48 does not need to be provided.

Next, the main effects of the first support column 14 of this embodiment will be described.
First, according to the first support pillar 14 of this embodiment, an inner steel pipe 42 is provided to form a double-pipe structure, so that in the event of a fire occurring outside or inside the automated warehouse 1, even if the outer steel pipe 40 melts locally and loses its buckling resistance, the inner steel pipe 42 can support the load, ensuring buckling resistance in the event of a fire.
Secondly, since concrete is filled between the double pipes, the inner steel pipe 42 is less susceptible to heat and will not melt in the event of a fire.
Third, because the inner steel pipe 42 is structurally wrapped in concrete, buckling resistance can be more reliably ensured. That is, by surrounding it with concrete, a confining effect (the effect of being able to estimate the "buckling length" where a compressive load acts shorter) is obtained, making the inner steel pipe 42 stronger than the inner steel pipe 42 alone, increasing buckling resistance, and ensuring its function as a buckling stopper for the first support column 14.

Next, the procedure (method) for assembling such a first support column 14 involves first welding and fixing the cargo receiving shelf section 20 to the outer circumferential surface of the outer steel pipe 40 of the first support column 14, and then filling the gap between the outer steel pipe 40 and the inner steel pipe 42 of the first support column 15 with filler material 44. In this way, the method for assembling the first support column 14 according to this embodiment includes the steps of welding and fixing the cargo receiving shelf section 20 to the outer circumferential surface of the outer steel pipe 40 of the first support column 14, and filling the gap between the outer steel pipe 40 and the inner steel pipe 42 of the first support column 15 with filler material 44. This ensures that heat is not lost by the inner filler material 44 when welding the cargo receiving shelf section 20, allowing for reliable and easy welding.

A method for assembling such a first support column 14 will now be described in more detail.
For example, a first assembly method for the first support 14 may include the steps of preparing an outer steel pipe 40 at the manufacturing plant of the rack 2 (the plant of the manufacturer that manufactures the rack 2), welding and fixing the cargo receiving shelf section 20 and the diagonal member 22 to the outer steel pipe 40, arranging the outer steel pipe 40 with the cargo receiving shelf section 20 and the diagonal member 22 welded and fixed thereto so that it is upright at the installation location of the rack 2 (the installation location of the user of the rack 2), preparing an inner steel pipe 42, inserting the inner steel pipe 42 into the outer steel pipe 40, filling the outer steel pipe 40 with concrete, and filling the inner steel pipe 42 with mortar.

Also, for example, a second assembly method for the first support 14 may include the steps of preparing the outer steel pipe 40 and inner steel pipe 42 at the rack 2 manufacturing factory, welding and fixing the load-receiving shelf section 20 and diagonal member 22 to the outer steel pipe 40, inserting the inner steel pipe 42 into the outer steel pipe 40, filling the outer steel pipe 40 with concrete, filling the inner steel pipe 42 with mortar, and arranging the outer steel pipe 40 made at the manufacturing factory using the above steps so that it stands upright at the installation location of the rack 2.

As shown in a modified example in Figure 7, in addition to the configuration of the outer steel pipe 40, inner steel pipe 42, filler material 44, and dowel reinforcement 46 of the first support column 14 described above, the inner steel pipe 42 may be filled with concrete material as a heat-absorbing material 52. In this modified example, mortar is filled to further enhance heat absorption. Such heat-absorbing material 52 can further improve the fire resistance of the first support column 14.

In addition, if the automated warehouse 1 is a warehouse that stores hazardous materials, some of the multiple second support columns 18 may be replaced with first support columns 14 having the above-mentioned configuration, as appropriate, depending on the required fire resistance performance.

Next, a rack 2 according to a modification of this embodiment will be described with reference to Figures 8 and 9. Figure 8 is a view of the rack unit according to a modification of this embodiment as seen from the outer wall side, similar to Figure 3, and Figure 9 is a perspective view of the rack unit according to the modification of this embodiment shown in Figure 8 as seen from the crane aisle side.
The rack 2 according to this modification includes first support columns ("first support columns") 15 (two columns in the rack unit 17 shown in each drawing) having a double-tube structure similar to that of the above-described embodiment, and second support columns ("second support columns") 19 (six columns in the rack unit 17 shown in each drawing) made of steel pipes with a square cross section. That is, the rack 2 includes three front second support columns 19a, three rear second support columns 19b, and two rear first support columns 15b fixed as support columns to the two rear second support columns 19b, respectively.

Of these supports, a multi-tiered load-receiving shelf section ("shelf support member") 20 is fixed by welding to the front second support 19a and the rear second support 19b arranged along the front-to-rear direction on both the left and right sides and the left-to-right center of the rack unit 17 shown in Figures 8 and 9.
8 and 9, the front second support columns 19a and the rear second support columns 19b on both the left and right sides of the rack unit 17 are connected to each other by a plurality of diagonal members 23 and connecting members 25 that extend in the front-to-rear and horizontal directions. By connecting in this manner, the front second support columns 19a, the rear second support columns 19b, the diagonal members 23, and the connecting members 25 are provided as members that constitute a truss structure.
On the other hand, the front second support pillar 19a and the rear second support pillar 19b, which are located in the center in the left-right direction, are connected to each other by a connecting member 25 that extends in the front-rear direction and horizontally, as shown in the drawing.
In this modified rack unit 17, the two first pillars 15 are provided as support pillars for a truss structure composed of the second pillars 19 and diagonal members 23, and the exterior wall 10 is attached to these support pillars, the first pillars 15.

In this way, the modified rack 2 has a first frame unit which has a first support pillar 15, and second support pillars 19a, 19b connected to each other by diagonal members 23 and connecting members 25, and is provided with a cargo receiving shelf section 21, and a second frame unit which does not have a support pillar, and second support pillars 19a, 19b connected to each other by connecting members 24, and is provided with a cargo receiving shelf section 20, and these first frame units and second frame units are arranged alternately in the left-right direction (see Figure 2) to form a rack unit 17.
8 and 9 show a part of such a rack unit 17, showing two first frame units and one second frame unit provided therebetween.

The rack unit 17 shown in Figures 8 and 9 has two rows of storage shelves in the left-right direction and three tiers in the up-down direction. As shown in Figures 8 and 9, the second supports 19a, 19b arranged along the front-to-rear direction are connected (assembled) to each other by the front horizontal member 27a, the rear horizontal member 27b, the flat brace 29, and the rear brace 31 to form the rack assembly 4.

In the figure, reference numeral 35 denotes mounting members for attaching each end of the rear brace 31 and each end of the rear horizontal member 27b to the second support pillar 19 using fastening members, reference numeral 37 denotes a fixing member provided on the second support pillar 19 for fixing the first support pillar 15 to the second support pillar 19, and reference numeral 39 denotes a joint (exterior wall fixing portion) for attaching the exterior wall 10 to the first support pillar 14.

Here, the first support pillar 15 according to this modified embodiment is attached to the second support pillar 19 as a support pillar and supports the exterior wall 10 (see Figure 1). The first support pillar 15 and second support pillar 19 according to this modified embodiment function as structural pillars, similar to the embodiment described above, and have buckling resistance sufficient to withstand long-term loads during normal use and short-term loads during earthquakes in the automated warehouse 1. The function and effect of the first support pillar 15 in the event of a fire are similar to those of the first support pillar 14 according to the embodiment described above, and therefore will not be described here.

In the above-described embodiment and its modified examples, the outer steel pipe 40 has a square cross section, but an outer steel pipe having a rectangular cross section may also be used. Also, the inner steel pipe 42 may have a rectangular cross section instead of a circular cross section.
The filler 44 may be made of the above-mentioned concrete material or any other heat-resistant, high-strength material. The heat-absorbing material 52 may be made of the above-mentioned concrete material or any other heat-absorbing material.
Furthermore, in cases where the automated warehouse 1 is a warehouse for storing hazardous materials, depending on the required fire resistance performance, some of the multiple second pillars 19 may be replaced with first pillars 15 having the above-described configuration as appropriate.

Next, the effects of the rack 2 of the structure-integrated automated warehouse 1 according to the embodiment and its modified example of the present invention will be described.
First, the rack 2 of the structure-integrated automated warehouse 1 according to this embodiment and its modified examples includes a plurality of support columns 14, 15, 18, 19, a plurality of connecting members 22, 23, 24, 25, 26, 27, 28, 29, 30, 31 that connect the plurality of support columns to one another, a plurality of receiving shelf sections 20, 21 that are attached to the plurality of support columns and supported indirectly or directly by the plurality of support columns, and an outer wall 10 that is supported indirectly or directly by the plurality of support columns, and the plurality of connecting members include a plurality of diagonal members 22, 23 that connect the plurality of support columns diagonally to form a truss structure, thereby forming the rack 2 of the structure-integrated automated warehouse 1 having a truss structure. Note that the expression "outer wall supported by a plurality of support columns" indicates a feature of the "structure-integrated automated warehouse (1)" and also means "an outer wall that is supported directly or indirectly by a plurality of support columns."
In the rack 2 of this automated warehouse 1, the multiple pillars include first pillars 14, 15 each having an outer steel pipe 40, an inner steel pipe 42, and a filler material 44 therebetween, and the exterior wall 10 is supported by the first pillars 14, 15. Therefore, in the first pillars 14, 15, which are structural pillars supporting the exterior wall 10 and which must have fire resistance, the outer steel pipe 40 supports the load under normal conditions, while in the event of a fire outside or inside the automated warehouse, the strength of the inner steel pipe 42 suppresses buckling of the first pillars 14, 15, thereby suppressing the collapse of the exterior wall 10. As a result, in the pillars (first pillars) 14, 15 to which the exterior wall 10 is attached, the thickness of the fire-resistant covering material 48 provided on the pillars 14, 15 can be reduced compared to conventional methods or eliminated, and the collapse of the exterior wall 10 and the resulting collapse of the automated warehouse 1 can be prevented even in the event of a fire.

In addition, in this embodiment, the diagonal member 22 connects the first support column 14b and the second support column 18a to form a truss structure, and the exterior wall 10 is supported by the first support column 14b that forms the truss structure. This more effectively prevents the collapse of the exterior wall 10 of the automated warehouse 1, which is configured as a truss structure, in the event of a fire.

In addition, in a modified version of this embodiment, the diagonal members 23 connect the second support columns 19a, 19b to form a truss structure, the first support column 15b is attached to the second support column 19b of this truss structure as a support column, and the exterior wall 10 is supported by the first support column 15b as a support column. This makes it possible to more effectively prevent the collapse of the exterior wall 10 in the event of a fire, even in an automated warehouse 1 in which the exterior wall 10 is supported by the support columns of a truss structure.

In addition, in this embodiment and its variations, the outer steel pipes 40 of the first supports 14, 15 are steel pipes with a rectangular cross section, which allows them to effectively support long-term loads (static loads) under normal conditions and short-term loads (dynamic loads) during earthquakes. Furthermore, the inner steel pipes 42 of the first supports 14, 15 are steel pipes with a circular cross section, which has an anti-buckling effect, thereby improving the buckling resistance of the outer steel pipe 40. Furthermore, because the inner steel pipe 42 is a steel pipe with a circular cross section and the filler material 44 is concrete material, a sufficient distance can be maintained between the inner steel pipe 42 and the outer steel pipe 40, effectively utilizing the heat absorption effect of the concrete material.

In addition, in this embodiment and its modified examples, multiple dowel bars 46 are welded to the outer surface of the inner steel pipe 42 of the first supports 14, 15. These dowel bars 46 increase the shear strength of the first supports 14, 15, thereby improving the buckling resistance of the first supports 14, 15.

Furthermore, in this embodiment and its variations, the multiple dowel reinforcement bars 46 are arranged inside the outer steel pipe 40 so as to extend diagonally from the four corners of the rectangular cross-section outer steel pipe 40. This allows the central position of the inner steel pipe 42 (the central position within the outer steel pipe 40) to be determined (centered) when the inner steel pipe 42 is placed inside the outer steel pipe 40. In particular, the closer the dimensions of the dowel reinforcement bars 46 are to the dimensions that match the diagonal inner dimensions of the outer steel pipe 40, the more reliably such centering can be achieved. Furthermore, because the dowel reinforcement bars 46 are integrated with the concrete material, the shear strength of the first columns 14, 15 can be more effectively increased.

In addition, in a modified version of this embodiment, the inside of the inner steel pipes 42 of the first supports 14, 15 is filled with heat-absorbing material 52, which further improves the fire resistance of the first supports 14, 15.

Furthermore, in this embodiment and its variations, the cargo receiving shelves 20, 21 are welded to the outer periphery of the outer steel pipe 40 of the first support pillars 14, 15, and the filler material 44 between the outer steel pipe 40 and the inner steel pipe 42 is filled in after the cargo receiving shelves 20, 21 are welded. This allows the cargo receiving shelves 20, 21 to have a simple shape (without requiring a special mounting structure using fastening members, for example), and also allows the cargo receiving shelves 20, 21 to be reliably welded to the support pillar 15 without heat loss due to the filler material 44.
