Description

The present invention relates to an article storage facility having a pillar member arranged along the vertical direction and a horizontal member arranged along the horizontal direction.

As a technique for constructing an article storage shelf (an example of an article storage facility) capable of storing articles by combining a column member along the vertical direction and a beam member along the horizontal direction, for example, Japanese Patent Application Laid-Open No. 2001-048324 (hereinafter referred to as JP-A-2001-048324). , Patent Document 1) discloses an article storage shelf configured as follows. Hereinafter, the reference numerals shown in parentheses in the description of the background technique are those of Patent Document 1.

The article storage shelf (1) of Patent Document 1 is used in an automated warehouse for automatically loading and unloading articles (w). In this article storage shelf (1), one end of the beam member (4) is swingably connected to the pillar member (2). Then, at the time of assembly at the installation site, the beam member (4) is swung in a horizontal posture, and the other end of the beam member (4) is the other pillar member (4) having no beam member (4). Connect to 2). As a result, the pair of adjacent column members (2) are connected to each other via the beam member (4). With such a configuration, in Patent Document 1, it is possible to improve the transport efficiency by folding the beam member (4) along the pillar member (2) at the time of transport. Further, in this structure, since the beam member (4) is swingable with respect to the column member (2), the pair of column members (2) can be easily connected to each other as described above and assembled. We are also trying to facilitate the work.

Japanese Unexamined Patent Publication No. 2001-048324

However, in the structure of Patent Document 1, since the joint portion between the beam member (4) and the column member (2) allows the beam member (4) to swing, it is caused by an earthquake or the like. It is difficult to ensure high durability against the generated horizontal force. On the other hand, it is possible to increase the durability against horizontal force by increasing the rigidity of the joint portion between the beam member (4) and the column member (2), but in that case, the ease of assembly work is possible. Will decrease.

In view of the above situation, it is desired to realize an article storage facility capable of ensuring high durability against horizontal force and facilitating assembly work.

The article storage facility according to the present disclosure includes a plurality of rigid units in which one pillar member arranged along the vertical direction and at least one beam member arranged along the horizontal direction are rigidly joined. In the article storage facility, the plurality of rigid units are spaced along a first direction which is a longitudinal direction of the beam member and a second direction which is orthogonal to the first direction in a vertical direction. A plurality of the rigid units arranged so as to be arranged side by side in a space and arranged along the second direction are connected to each other by a girder member arranged along the second direction, and an article support portion for supporting the article is provided. The article support portion is supported by a plurality of the pillar members, the article support portion is composed of a pair of the girder members adjacent to each other in the first direction, and a reinforcing member is provided between the pillar member and the beam member. A pair of rigid units are connected to each of the column member and the beam member, the girder member is connected to the reinforcing member without the beam member, and the reinforcing members are adjacent to each other along the first direction. The ends of the beam members in each of the above are connected to each other , and the plurality of pillar members arranged in the second direction are connected to each other by the girder member along the second direction via the reinforcing member. The plurality of pillar members arranged in the first direction are connected by the plurality of beam members along the first direction via the reinforcing member .

According to this configuration, since the column member and the beam member are rigidly joined, it is possible to secure high durability against horizontal force generated by an earthquake or the like. Further, since the structure is such that the pair of beam members of the rigid unit in which the column member and the beam member are rigidly joined are connected to each other, the column member and the beam member are erected along the vertical direction, for example, when assembling at the installation site. Since it is not necessary to perform work such as joining the beam member to the column member and only connecting the ends of the beam member to each other, it is possible to facilitate the assembly work. Further, the article supporting portion is supported by a plurality of pillar members, and it is difficult for the supporting load of the article supporting portion to act on the beam member. Therefore, according to this configuration, the rigidity of the beam configured by connecting a plurality of beam members is insufficient even though the ends of the beam members in each of the pair of adjacent rigid body units are connected to each other. Is unlikely to occur.

Further features and advantages of the techniques according to the present disclosure will be further clarified by the following illustration of exemplary and non-limiting embodiments described with reference to the drawings.

The female threaded portion of the mounting portion 12 is provided at a position corresponding to each of the plurality of reinforcing member fastening holes 4h of the reinforcing member 4 described later.

[Reinforcing member]
As shown in FIGS. 4 and 5, the reinforcing member 4 is a member that constitutes a part of the rigid body unit U, and is provided between the column member 1 and the beam member 2. The reinforcing member 4 is provided to increase the rigidity of the joint portion between the column member 1 and the beam member 2. Further, as will be described later, the reinforcing member 4 also has a function of supporting the article supporting portion S (girder member 3) by the column member 1. In the present embodiment, the column member 1 and the reinforcing member 4 are fastened and fixed by the first fastening member B1, and the beam member 2 and the reinforcing member 4 are fixed inseparably. In the example shown in FIG. 4, a joint portion J is formed between the reinforcing member 4 and the beam member 2. In this example, the joint portion J is a welded joint portion in which the reinforcing member 4 and the beam member 2 are joined by welding. In the illustrated example, the joint portion J is formed at the end portion of the reinforcing member 4 and the beam member 2 on both the upper surface portion and the lower surface portion on the reinforcing member 4 side (column side surface portion 11 side).

As shown in FIG. 4, the reinforcing member 4 includes a reinforcing member main body portion 40. The reinforcing member main body 40 is formed in a flat plate shape along the first direction H1 and the vertical direction, and has a first surface 40a facing the column member 1 side in the second direction H2 and a beam member 2 side in the second direction H2. It has a second surface 40b facing the surface. Then, the above-mentioned joint portion J is formed on the second surface 40b of the reinforcing member main body portion 40, and the beam member 2 is joined. On the other hand, as shown in FIG. 5, the first surface 40a of the reinforcing member main body 40 abuts on the column member 1. As shown in FIG. 4, the reinforcing member main body 40 has an upper projecting portion 41 projecting upward from the beam member 2 and a lower projecting portion 42 projecting downward from the beam member 2. There is.

The width of the upper protrusion 41 in the first direction H1 is wider than the width of the pillar member 1 in the first direction H1. In other words, the upper protruding portion 41 has an overlapping portion that overlaps with the pillar member 1 and a non-overlapping portion that does not overlap with the pillar member 1 in the second direction H2 view. The upper protruding portion 41 is provided with an upper connecting portion 41L connected to the pillar member 1. The upper connecting portion 41L is provided at an overlapping portion (overlapping portion in the second direction H2 view) with the pillar member 1 in the upper protruding portion 41. In the present embodiment, the upper connecting portion 41L is provided with a plurality of reinforcing member fastening holes 4h that penetrate the reinforcing member main body portion 40 in the second direction H2, and the first fastening holes 4h are provided in each of the reinforcing member fastening holes 4h. Member B1 is inserted. Here, the first fastening member B1 is, for example, a bolt. Then, the first fastening member B1 inserted into the reinforcing member fastening hole 4h is screwed into the female screw portion constituting the mounting portion 12 of the pillar member 1 described above, whereby the pillar member 1 and the reinforcing member 4 are fastened and fixed. Will be done. In this example, the reinforcing member fastening hole 4h is a round hole having no threaded portion.

In this example, the mounting portion 12 is a reverse female screw portion (female screw portion) formed in the through hole of the column side surface portion 11 and a nut member arranged on the opposite side of the column side surface portion 11 with the reinforcing member 4 interposed therebetween. It has a positive female threaded portion. In the positive female thread portion, a thread is formed along a normal screw tightening direction, and in the reverse female thread portion, a thread is formed in a direction opposite to the normal screw tightening direction. The bolt as the first fastening member B1 has a reverse male threaded portion formed on the shaft portion and a positive male threaded portion formed axially adjacent to the reverse male threaded portion and having a smaller diameter than the reverse male threaded portion. , Have. Here, the inverted male threaded portion of the first fastening member B1 is screwed into the inverted female threaded portion of the mounting portion 12. Then, the positive female screw portion (nut member) of the mounting portion 12 is screwed by rotating relative to the positive male screw portion of the first fastening member B1 in the normal screw tightening direction. With such a configuration, it is possible to suppress the rotation when the nut (mounting portion 12) is attached to the first fastening member B1. However, without being limited to such a configuration, the first fastening member B1 may be a normal one having only a positive male screw portion, and the mounting portion 12 may have only a positive female screw portion (nut member only). It may have. In this case, the positive female screw portion may be, for example, a nut member fixed to the surface of the column side surface portion 11 opposite to the surface with which the reinforcing member 4 abuts by welding or the like.

These plurality of reinforcing member fastening holes 4h are arranged at intervals from each other in the overlapping portion overlapping with the column member 1. In the illustrated example, four reinforcing member fastening holes 4h are arranged in the upper connecting portion 41L at intervals in the first direction H1 and the vertical direction, respectively. In this way, by providing a plurality of reinforcing member fastening holes 4h arranged at intervals from each other, it is restricted that the reinforcing member 4 rotates with respect to the column member 1 in a directional view along the second direction H2. .. Therefore, the rigidity of the joint portion between the column member 1 and the reinforcing member 4 can be ensured high, and the rigidity of the joint portion between the beam member 2 joined (welded jointly) to the reinforcing member 4 and the column member 1 is also increased. It can be secured high.

Further, in the present embodiment, the lower protruding portion 42 of the reinforcing member main body 40 is also provided with a lower connecting portion 42L connected to the column member 1. As a result, the rigidity of the joint portion between the column member 1 and the reinforcing member 4 can be further increased, and the rigidity of the joint portion between the column member 1 and the beam member 2 can be further increased.

The configuration of the lower protrusion 42 will be specifically described. In the present embodiment, the width of the lower protrusion 42 in the first direction H1 is formed so as to correspond to the width of the pillar member 1 in the first direction H1. Therefore, the lower protruding portion 42 has an overlapping portion that overlaps with the pillar member 1 in the second direction H2 view. In this example, unlike the upper protruding portion 41, the lower protruding portion 42 is mostly an overlapping portion that overlaps with the pillar member 1, and the non-overlapping portion that does not overlap with the pillar member 1 is small.

The lower connecting portion 42L of the lower protruding portion 42 is provided at an overlapping portion (overlapping portion in the second direction H2 view) with the pillar member 1 in the lower protruding portion 42. In the present embodiment, the lower connecting portion 42L is provided with a plurality of reinforcing member fastening holes 4h that penetrate the reinforcing member main body portion 40 in the second direction H2, and each of these reinforcing member fastening holes 4h is the first. The fastening member B1 is inserted. Then, similarly to the upper connecting portion 41L, the first fastening member B1 inserted into the reinforcing member fastening hole 4h is screwed into the female screw portion constituting the mounting portion 12 of the column member 1 to reinforce the column member 1. The member 4 is fastened and fixed. In the lower connecting portion 42L as well, as in the upper connecting portion 41L, a plurality of (four in this example) reinforcing member fastening holes 4h are spaced apart from each other in the overlapping portion overlapping with the column member 1. Have been placed.

As shown in FIG. 4, the reinforcing member 4 includes a girder support portion 43 that supports the girder member 3. The girder support portion 43 is arranged above the beam member 2, and is formed in the upper protruding portion 41 above the beam member 2 in the present embodiment. To add an explanation, the girder support portions 43 are formed on both sides of the first direction H1 in the upper protrusion 41. As shown in FIG. 4, in each reinforcing member 4 of the pair of rigid body units U, the pair of girder members 3 adjacent to each other in the first direction H1 are supported by the girder support portions 43 on the sides adjacent to each other.

In the present embodiment, the girder support portion 43 is formed in a plate shape extending from the reinforcing member main body portion 40 toward the second direction H2 (see FIG. 5). Here, the girder support portion 43 is formed in a plate shape along the second direction H2 and along the first direction H1 or the vertical direction. As a result, the girder member 3 extending along the second direction H2 can be stably supported. For example, the girder support portion 43 is formed by bending a part of the outer edge portion of the flat plate-shaped member constituting the reinforcing member main body portion 40 toward the second direction H2.

As shown in FIG. 4, in the present embodiment, the girder support portion 43 is the first girder support portion 43a extending along the first direction H1 and the first girder support portion 43a above the first girder support portion 43a in the first direction H1. The second girder support 43b, which is arranged outside the first direction H1 and extends along the first direction H1, is arranged between the first girder support 43a and the second girder support 43b in the vertical direction and the first direction H1. It has a third girder support portion 43c extending along the vertical direction. In other words, the girder support portion 43 has a stepped support surface formed by the first girder support portion 43a, the third girder support portion 43c, and the second girder support portion 43b. Although the details will be described later, the first girder support portion 43a, the second girder support portion 43b, and the third girder support portion 43c of the girder support portion 43 are arranged so as to follow the cross-sectional shape of the girder member 3 to be supported. ing.

[Girder member]
The girder member 3 is arranged along the second direction H2 (horizontal direction) and is supported by the pillar member 1. In this embodiment, as shown in FIG. 1, two girder members 3 are supported for each of the pair of pillar members 1. Then, a pair of girder members 3 are arranged so as to face the first direction H1 between the pair of pillar members 1 adjacent to each other in the first direction H1. In other words, as shown in FIG. 4, the pair of girder members 3 are arranged inside the first direction H1 with respect to the pair of pillar members 1. On the other hand, as shown in FIG. 1, when one rigid body unit U is used as a reference, girder members 3 are arranged on both sides of the first direction H1 in the column member 1. The one girder member 3 is supported by a plurality of pillar members 1 arranged along the second direction H2.

In the present embodiment, the girder member 3 is directly supported by the reinforcing member 4, and is indirectly supported by the column member 1 via the reinforcing member 4. More specifically, as shown in FIG. 4, the girder member 3 is supported from below and from the outside in the first direction H1 by the girder support portion 43 in the reinforcing member 4. Therefore, the weight of the girder member 3 and the load of the article W supported by the girder member 3 and the load of the article transfer device 6 are transmitted to the reinforcing member 4 and also to the column member 1 via the reinforcing member 4.

As shown in FIG. 4, in the present embodiment, the girder member 3 has a first horizontal portion 31a extending along the first direction H1 and a first horizontal portion 31a above the first horizontal portion 31a. A second horizontal portion 31b arranged outside the one direction H1 and extending along the first direction H1 and connecting these between the first horizontal portion 31a and the second horizontal portion 31b in the vertical direction and the first direction H1. It also has a vertical portion 31c that extends along the vertical direction. In other words, in the girder member 3, the first horizontal portion 31a, the vertical portion 31c, and the second horizontal portion 31b form a stepped surface. In the illustrated example, the vertical portion 31c connects the outer end of the first direction H1 in the first horizontal portion 31a and the inner end of the first direction H1 in the second horizontal portion 31b. The first horizontal portion 31a is supported from below by the first girder support portion 43a of the reinforcing member 4, the second horizontal portion 31b is supported from below by the second girder support portion 43b, and the vertical portion 31c is the first. It is supported by the third girder support portion 43c from the outside of the one-way H1.

As described above, the article support portion S that supports the article W is configured by using the girder member 3. In the present embodiment, the article support portion S is composed of a pair of girder members 3 adjacent to each other in the first direction H1. That is, the article W is supported by the article support portion S by being placed on the pair of girder members 3 so as to straddle the pair of girder members 3 arranged at intervals in the first direction H1. ..

As shown in FIGS. 2 to 4, in the present embodiment, a device support surface 3a for supporting the above-mentioned article transport device 6 is formed on the upper surface of the first horizontal portion 31a of the girder member 3. The device support surface 3a supports the traveling wheel 61a in the article transporting device 6 from below, and is a rolling surface on which the traveling wheel 61a rolls. Then, on the inner surface of the vertical portion 31c of the girder member 3 in the first direction H1, the movement of the article transfer device 6 in the first direction H1 is restricted and the guide surface for guiding the article transfer device 6 to the second direction H2. 3c is formed. The guide surface 3c supports the guide ring 61b in the article transport device 6 from the outside of the first direction H1 and serves as a rolling surface on which the guide ring 61b rolls.

Further, an article support surface 3b for supporting the article W is formed on the upper surface of the second horizontal portion 31b of the girder member 3. In this example, the pair of article support surfaces 3b of the pair of girder members 3 constitutes the above-mentioned article support portion S. The article support portion S is connected to the reinforcing member 4, and the article support surface 3b (second horizontal portion 31b) constituting the article support portion S is supported by the second girder support portion 43b of the reinforcing member 4. Therefore, the load of the article W or the like supported by the article support portion S is transmitted to the reinforcing member 4, and is transmitted to the pillar member 1 via the reinforcing member 4. In other words, the article support portion S is connected to the reinforcing member 4 without the beam member 2, so that the load supported by the article support portion S is basically not transmitted to the beam member 2. Further, in this example, the girder member 3 supports not only the load of the article W supported by the article support surface 3b (article support portion S) but also the weight of the article transfer device 6. Similarly to the above, the weight of the article transporting device 6 is transmitted to the reinforcing member 4, and is transmitted to the column member 1 via the reinforcing member 4, so that it is basically not transmitted to the beam member 2. The device support surface 3a, the article support surface 3b, and the guide surface 3c are formed so as to extend along the second direction H2.

In the present embodiment, the girder member 3 has an inner locking portion 31e that abuts on the reinforcing member 4 from the inside of the first direction H1 and an outer locking portion 31d that abuts on the reinforcing member 4 from the outside of the first direction H1. Further has. The inner locking portion 31e and the outer locking portion 31d are configured to sandwich the reinforcing member 4 from both sides of the first direction H1, whereby the girder member 3 is first with respect to the reinforcing member 4. It is locked so as not to move in the direction H1. In the illustrated example, the inner locking portion 31e is formed so as to bend downward (vertically downward) from the inner end portion of the first horizontal portion 31a in the first direction H1. The outer locking portion 31d is formed so as to bend downward (vertically downward) from the outer end portion of the first horizontal portion H1 in the second horizontal portion 31b. It is preferable that the girder member 3 is fixed to the reinforcing member 4 by a fastening member or the like (not shown).

[Beam member]
The beam member 2 is arranged along the first direction H1 (horizontal direction) and constitutes a part of the rigid body unit U. As shown in FIG. 5, the beam member 2 has a beam side surface portion 21 facing the column side surface portion 11 of the column member 1 in the second direction H2. The above-mentioned reinforcing member 4 is provided between the beam side surface portion 21 and the column side surface portion 11. The plurality of beam members 2 arranged along the first direction H1 are arranged so that the respective beam side surface portions 21 are at the same position in the second direction H2.

As shown in FIG. 4, the beam member 2 has a jointed portion 22 to be joined to the reinforcing member 4. The joined portion 22 is formed between both ends of the beam member 2 in the first direction H1 (beam member ends 2E and 2E on both sides in the first direction H1). In other words, the joined portion 22 is formed in a portion of the beam member 2 other than the beam member end portions 2E and 2E on both sides. In this example, the jointed portion 22 is formed in the central region of the beam member 2 in the first direction H1. The above-mentioned joint portion J for joining the reinforcing member 4 and the beam member 2 is formed at a portion corresponding to the jointed portion 22. As a result, in this example, the beam member 2 and the reinforcing member 4 are inseparably fixed.

As shown in FIG. 6, in the present embodiment, the beam member 2 has a wall portion 23 along the vertical direction and an upper side protruding (horizontally protruding in this example) from the upper end of the wall portion 23 toward the second direction H2. It includes a projecting portion 24 and a lower projecting portion 25 projecting from the lower end of the wall portion 23 toward the second direction H2 (horizontally projecting in this example). In other words, the beam member 2 has a square C-shape having a cross-sectional shape cut at the vertical surface along the second direction H2. In this example, the beam member 2 is made of channel steel. However, the beam member 2 is not limited to the shaped steel having the cross-sectional shape shown in FIG. 6, and may be a lip channel steel, a light channel steel, an angle steel, or the like.

As described above, the pair of beam members 2 are connected to each other at the ends 2E of the respective beam members. In the present embodiment, as shown in FIGS. 4 and 5, a connecting portion (hereinafter referred to as a beam member connecting portion L) in which the ends of the pair of beam members 2 (beam member end portions 2E to each other) are connected to each other. Is arranged at the intermediate position M of the installation interval of the pair of pillar members 1 adjacent to each other along the first direction H1. Ideally, the intermediate position M is a bending moment generated in a beam (here, an integral member composed of a pair of beam members 2) when a horizontal force acts on the article storage facility 100 due to an earthquake, wind, or the like. It is located at the so-called anti-curvature point, which becomes zero. As a result, it is possible to make it difficult for a large load to act on the beam member connecting portion L to which the pair of beam members 2 are connected. The "beam member end 2E" has a wide area, and includes a tip of the beam member 2 in the first direction H1 and a portion extending from this tip to the first direction H1.

As shown in FIGS. 4 to 6, in the present embodiment, the beam member ends 2E of the pair of beam members 2 are connected to each other via the connecting member 5. Here, the connecting member 5 is formed in a plate shape (rectangular plate shape in this example). Then, the connecting member 5 is arranged so as to overlap both of the beam member end portions 2E of the pair of beam members 2 in the second direction H2 view, and the beam member end portions 2E of the pair of beam members 2 overlap at the overlapping portion. It is fixed for each. Further, in this example, the connecting member 5 has a non-overlapping portion that does not overlap with both of the beam member end portions 2E of the pair of beam members 2 in the second direction H2 view at the intermediate position M. Therefore, the pair of beam members 2 are arranged with a gap in the first direction H1. As a result, the pair of beam members 2 are connected via the connecting member 5, but are not in direct contact with each other, and have a connecting structure in which minute mutual movement is allowed. Therefore, even when a horizontal force acts on the article storage facility 100, the horizontal force is absorbed by the mutual motion of the pair of beam members 2, and the toughness of the beam (integrated member composed of the pair of beam members 2) is insufficient. Is unlikely to occur.

As shown in FIGS. 4 to 6, in the present embodiment, the beam member end portion 2E is formed with a fastened portion 26 to be fastened by the second fastening member B2. As shown in FIG. 6, in this example, the fastened portion 26 has a beam member fastening hole 23h that penetrates the wall portion 23 in the second direction H2.

In the present embodiment, a plurality of beam member fastening holes 23h are formed side by side in the first direction H1. In the illustrated example, the two beam member fastening holes 23h are arranged in a row along the first direction H1. Then, as shown in FIG. 6, the connecting member 5 is in contact with each of the second fastening surfaces 26b of the pair of beam members 2 from one side of the second direction H2, and the pair is paired by the second fastening member B2. It is fastened and fixed to each of the beam members 2. In the present embodiment, as shown in FIG. 6, a through hole 5h penetrating in the second direction H2 is formed at a position corresponding to the beam member fastening hole 23h in the connecting member 5. The second fastening member B2 is inserted into the beam member fastening hole 23h and the through hole 5h of the connecting member 5 to fasten and fix the beam member 2 and the connecting member 5. In the illustrated example, the plate 99 is arranged between the connecting member 5 and the head of the bolt as the second fastening member B2. Here, one plate 99 is provided for each of the two second fastening members B2.

As shown in FIGS. 4 and 5, the connecting member 5 uses beam member fastening holes 23h provided at two locations for one beam member 2, and a pair of beam members are provided by a total of four second fastening members B2. It is fastened and fixed to each of 2. However, if it is desired to further strengthen the connection between the pair of beam members 2, one beam member 2 may be fastened and fixed by using three or more second fastening members B2. Further, when it is desired to increase the degree of freedom of mutual movement in the pair of beam members 2, one second fastening member B2 for each beam member 2 may be used for fastening and fixing.

According to the article storage equipment 100 described above, it is possible to secure high durability against horizontal force and to facilitate assembly work.

2. 2. Other Embodiments Next, other embodiments of the article storage facility will be described.

(1) In the above embodiment, the beam member connecting portions L in which the beam member end portions 2E of the pair of beam members 2 are connected to each other are installed at intervals of the pair of column members 1 adjacent to each other along the first direction H1. An example of being arranged at the intermediate position M of the above was described. However, the beam member connecting portion L may be arranged between a pair of column members 1 adjacent to each other along the first direction H1 without being limited to such an example. Therefore, the beam member connecting portion L is arranged at a position biased to either one side of the first direction H1 with respect to the intermediate position M of the installation interval of the pair of column members 1 adjacent to each other along the first direction H1. You may be.

(2) In the above embodiment, an example in which the beam member 2 and the reinforcing member 4 are inseparably fixed has been described. However, the beam member 2 and the reinforcing member 4 may be separably fixed by, for example, a fastening member such as a bolt, without being limited to such an example. In this case, the column member 1 may be inseparably fixed to the reinforcing member 4, or the beam member 2 and the reinforcing member 4 may be inseparably fixed.

(3) In the above embodiment, an example in which the beam member end portions 2E of the pair of beam members 2 are connected to each other via the connecting member 5 has been described. However, the present invention is not limited to such an example, and the pair of beam member end portions 2E may be directly connected to each other without via the connecting member 5. Also in this case, it is preferable that the pair of beam member end portions 2E are separably connected to each other by using a fastening member such as a bolt.

(4) In the above embodiment, an example in which the girder member 3 is configured to support both the article W and the article transfer device 6 has been described. However, without being limited to such an example, the girder member 3 may be configured to support only one of the article W and the article transport device 6.

(5) In the above embodiment, the configuration in which the girder member 3 constituting the article support portion S is supported by the pillar member 1 via the reinforcing member 4 has been described as an example. However, the support structure of the girder member 3 is not limited to such an example. For example, the girder member 3 may be directly supported by the column member 1 without the need for the reinforcing member 4. In this case, the girder member 3 and the pillar member 1 are directly connected. Alternatively, when the load acting on the girder member 3 is small or when the rigidity of the beam member 2 can be sufficiently ensured, the girder member 3 may be supported by the beam member 2.

(6) The configuration disclosed in each of the above-described embodiments can be applied in combination with the configurations disclosed in other embodiments as long as there is no contradiction. With respect to other configurations, the embodiments disclosed herein are merely exemplary in all respects. Therefore, various modifications can be appropriately made without departing from the spirit of the present disclosure.

3. 3. Outline of the above-described embodiment The outline of the article storage facility described above will be described below.

The article storage facility according to the present disclosure includes a plurality of rigid units in which one pillar member arranged along the vertical direction and at least one beam member arranged along the horizontal direction are rigidly joined. In the article storage facility, the plurality of rigid units are spaced along a first direction which is a longitudinal direction of the beam member and a second direction which is orthogonal to the first direction in a vertical direction. A plurality of the rigid units arranged so as to be arranged side by side in a space and arranged along the second direction are connected to each other by a girder member arranged along the second direction, and an article support portion for supporting the article is provided. , The ends of the beam members in each of the pair of rigid units adjacent to each other along the first direction, supported by the plurality of pillar members, are connected to each other.

According to this configuration, since the column member and the beam member are rigidly joined, it is possible to secure high durability against horizontal force generated by an earthquake or the like. Further, since the structure is such that the pair of beam members of the rigid unit in which the column member and the beam member are rigidly joined are connected to each other, the column member and the beam member are erected along the vertical direction, for example, when assembling at the installation site. Since it is not necessary to perform work such as joining the beam member to the column member and only connecting the ends of the beam member to each other, it is possible to facilitate the assembly work. Further, the article supporting portion is supported by a plurality of pillar members, and it is difficult for the supporting load of the article supporting portion to act on the beam member. Therefore, according to this configuration, the rigidity of the beam configured by connecting a plurality of beam members is insufficient even though the ends of the beam members in each of the pair of adjacent rigid body units are connected to each other. Is unlikely to occur.

here,
It is preferable that the connecting portion in which the ends of the pair of beam members are connected to each other is arranged at an intermediate position between the installation intervals of the pair of pillar members adjacent to each other along the first direction.

According to this configuration, even when a horizontal force is applied to the article storage facility, the connecting portion between the ends of the pair of beam members can be arranged at the inflection point where the bending moment becomes zero. Therefore, in a configuration in which the ends of the beam members of the pair of rigid body units are connected to each other, it is easy to avoid applying a large load to the connected portions.

again,
A reinforcing member is provided between the column member and the beam member, the beam member and the reinforcing member are inseparably fixed, and the column member and the reinforcing member are fastened and fixed by a fastening member. Is suitable.

According to this configuration, since the reinforcing member is interposed in the joint between the column member and the beam member, it is easy to secure high rigidity of the rigid body joint portion between the column member and the beam member. Further, since the column member, the reinforcing member, and the beam member are detachably fastened and fixed by the fastening member, the column member, the reinforcing member, and the beam member can be transported in a state of being separated from each other. Therefore, according to this configuration, it is easy to transport the article storage facility to the installation site.

Here, in a configuration in which a reinforcing member is provided between the column member and the beam member,
It is preferable that the article support portion is connected to the reinforcing member without the beam member.

According to this configuration, the load of the article support portion and the article supported by the article support portion does not act on the beam member. Therefore, it is unlikely that the rigidity of the beam formed by connecting a plurality of beam members will be insufficient.

again,
The ends of the pair of beam members are connected to each other via a connecting member, and the connecting members are arranged so as to overlap both ends of the pair of beam members in the second direction view. It is preferable that the portion is fixed to each of the ends of the pair of beam members.

According to this configuration, in the connecting portion where the ends of the pair of beam members are connected to each other, it is easy to secure high rigidity against the shearing force generated in the connecting portion.

again,
It is preferable that the article transporting device for transporting the article to the article supporting portion is provided, the girder member is supported by the plurality of pillar members, and the article transporting device is supported by the girder member.

According to this configuration, it can be suitably applied to an automated warehouse that transports and stores articles. Further, in addition to the support load of the article support portion, the support load of the article transfer device is also configured to be difficult to act on the beam member. Therefore, according to this configuration, the rigidity of the beam configured by connecting a plurality of beam members is insufficient even though the ends of the beam members in each of the pair of adjacent rigid body units are connected to each other. Is unlikely to occur.

The technique according to the present disclosure can be used for an article storage facility having a pillar member arranged along the vertical direction and a horizontal member arranged along the horizontal direction.
