The shelf 210 has a framework structure in which shapes, pipes, and the like are combined, and has a plurality of article storage sections 211 arranged in a matrix in the Y and Z directions. The article A is supported by a shelf member (not shown) in each article storage section 211 . Shelf 210 is an example of a framework structure. The X direction can also be referred to as the width direction of the shelf 210 , the Y direction can also be referred to as the longitudinal direction of the shelf 210 , and the Z direction can also be referred to as the height direction of the shelf 210 .

The transport path 220 is a space extending in the Y and Z directions with a substantially constant width in the X direction between the two shelves 210 .

The automated warehouse 200 also includes a transport mechanism 230 capable of transporting the article A. As shown in FIG. The transport mechanism 230 is, for example, a stacker crane having a mobile body 231 . The moving body 231 is configured to be movable in the horizontal direction (in this embodiment, the Y direction as an example) and the vertical direction (the Z direction) while holding the article A in the transport path 220, and is positioned at the carry-in position (not shown). ), a carry-out position (not shown), and a storage position (article storage section 211). However, the transport mechanism 230 may have a configuration different from that of the stacker crane, such as a movable cart system in which a plurality of movable carts that move only in the horizontal direction are provided in the vertical direction.

As shown in FIGS. 2 and 3, shelf 210 has legs 213 . A frame forming the shelf 210 has a column 212 extending in the vertical direction, and a leg portion 213 is a lower portion of the column 212 .

The post-installed anchor 105 has a stud bolt 105a protruding upward from the upper surface 100a of the concrete of the raft foundation 100, and the flange 213a is sandwiched between the nut 107 fastened to the stud bolt 105a and the upper surface 100a. is in place and fixed. With such a configuration, the leg portion 213 can be more firmly fixed to the raft foundation 100 via the fixing member 106 and the post-installed anchor 105 . Note that the stud bolt 105a can also be referred to as a protrusion.

FIG. 4 is a side view showing reinforcing bars 11 and 12, support members 104, post-installed anchors 105, fixing members 106, and legs 213 in the raft foundation 100, viewed in the opposite direction of the X direction. . 5 is a side view showing reinforcing bars 11 and 12, post-installed anchors 105, fixing members 106, and legs 213 in the raft foundation 100, viewed in the Y direction. 4 and 5, illustration of concrete is omitted, and in FIG. 5, illustration of the support member 104 is also omitted.

The raft foundation 100 that supports the automated warehouse 200 contains reinforced concrete. A plurality of substantially horizontal mesh-like reinforcing bars 11 and 12 are embedded in the concrete. 4 and 5 show the vicinity of the substantially horizontal upper surface 100a of the mat foundation 100. FIG. That is, the reinforcing bars 11 and 12 shown in FIGS. 4 and 5 are arranged at positions relatively close to the top surface 100a, for example, at positions about 50 [mm] below the top surface 100a. In addition, although not shown, substantially horizontal mesh-like reinforcing bars are also arranged at other heights, such as near the bottom surface where the slab foundation 100 is constructed, within the slab foundation 100 .

The reinforcing bars 11 extend horizontally substantially along the X direction and are arranged at predetermined intervals in the Y direction. The reinforcing bars 12 extend horizontally substantially along the Y direction and are arranged at predetermined intervals in the X direction. In this specification, "arranging" a member such as the reinforcing bars 11, 12 does not mean placing the member temporarily, but placing the member in a predetermined position, that is, in a positioned state. It means to set

The fixing member 106 is embedded in the concrete of the raft foundation 100 in a partially exposed state. The fixing member 106 has a fixing plate 106a and an anchor portion 106b.

The fixing plate 106a is a portion of the fixing member 106 that is fixed to the flange 213a of the leg portion 213 of the automated warehouse 200, and has a plate-like shape that extends substantially horizontally. That is, the fixed plate 106a intersects and is orthogonal to the Z direction, and extends substantially along the X and Y directions. Further, as shown in FIGS. 4 and 5, the fixing plate 106a is positioned above the plurality of reinforcing bars 11,12.

The fixing plate 106a is provided such that a surface 106a1 as an end surface in the Z direction is substantially horizontal and exposed from the upper surface 100a of the placed concrete. The surface 106a1 is substantially flush with the upper surface 100a of the concrete, or is positioned slightly above the upper surface 100a.

FIG. 6 is a plan view showing the reinforcing bars 11 and 12, the support member 104, the fixing member 106, and the flange 213a of the leg portion 213 in the raft foundation 100. FIG. 6, illustration of the concrete, the post-installed anchor 105, and the height adjustment bolt 213b and nut 213c of the leg portion 213 is omitted.

As shown in FIG. 6, the fixing plate 106a has a square shape in plan view. In addition, the fixed plate 106a has a rectangular shape that has sides extending in the X direction and sides extending in the Y direction, and is long in the Y direction.

As shown in FIGS. 4 and 5, the anchor portion 106b has an elongated rod-like shape and extends downward in the direction opposite to the Z direction, ie, downward, from approximately the central portion of the fixing plate 106a. The anchor portion 106b is integrated with the fixing plate 106a by being welded to the fixing plate 106a, for example. The anchor portion 106b penetrates between the meshes of the reinforcing bars 11 and 12, and its lower end 106b1 is positioned below the reinforcing bars 11 and 12. As shown in FIG. With such a configuration, the length of the anchor portion 106b can be increased, and the pull-out resistance of the fixing member 106 can be increased. Note that the anchor portion 106b may be in contact with the reinforcing bars 11 and 12 as long as the fixing member 106 can be arranged with the required positioning accuracy.

As shown in FIGS. 4 and 6, the fixing plate 106a, that is, the fixing member 106, is supported and fixed to the reinforcing bars 11 and 12 via the support member 104. As shown in FIGS. Specifically, the fixed member 106 is supported by two support members 104 . Each of the support members 104 extends in the X direction and is supported by a plurality of reinforcing bars 12 extending in the Y direction and spaced apart from each other in the X direction. The fixed plate 106a is supported at both ends in a bridged state between two support members 104 having the same height and separated from each other in the Y direction. However, the supporting structure of the fixing member 106 by the supporting member 104 and the supporting member 104 is not limited to this, and the extending direction and number of the supporting members 104, the supporting position of the fixing plate 106a by the supporting member 104, etc. can be varied. can be changed. Also, the support member 104 is, for example, a channel material, but is not limited to this, and may be an H-shaped material, a square pipe, or the like.

The leg portion 213 has a flange 213a, a height adjusting bolt 213b and a nut 213c.

As described above, the flange 213a has a plate-like shape extending substantially horizontally. Also, as shown in FIGS. 4 and 5, the flange 213a rests on the fixed plate 106a. A bottom surface 213a1 of the flange 213a is flat and contacts the surface 106a1 of the fixing plate 106a.

As shown in FIG. 6, the flange 213a has a square shape in plan view. Moreover, the flange 213a has a substantially square shape having sides extending in the X direction and sides extending in the Y direction.

As shown in FIGS. 4 and 6, the fixing plate 106a extends under the flange 213a in the Y direction and the opposite Y direction with respect to the flange 213a. A portion of the fixing plate 106a that protrudes from the flange 213a in plan view is an overhanging portion 106a2. Overhanging portion 106a2 is an example of a first overhanging portion.

As shown in FIGS. 5 and 6, the flange 213a protrudes from the fixing plate 106a in the X direction and the opposite direction of the X direction with respect to the fixing plate 106a. A portion of the flange 213a that projects from the fixing plate 106a in plan view is an overhanging portion 213a3. The projecting portion 213a3 is an example of a second projecting portion.

As shown in FIGS. 4 and 6, the Y-direction and the opposite Y-direction edge of the flange 213a are joined to the overhanging portion 106a2 of the fixing plate 106a via the welding portion 108, respectively. The flange 213 a of the leg portion 213 is welded to the fixing plate 106 a of the fixing member 106 embedded in the mat foundation 100 , thereby fixing the flange 213 a , that is, the shelf 210 to the mat foundation 100 .

The welded portion 108 is a weld bead extending in the X direction and formed by arc welding, TIG welding, or the like, for example. Welded portion 108 is provided at a corner between the side surface of the edge of flange 213a and the upper surface (surface 106a1) of projecting portion 106a2. That is, the welded portion 108 is formed by fillet welding. Such fillet welding is possible by providing the projecting portion 106a2 on the fixing plate 106a. Note that the welded portion 108 may be formed by butt welding the portions where the edges of the flange 213a and the fixing plate 106a are aligned in the Z direction. However, fillet welding is easier to perform than butt welding, and it is easier to reduce the impact of welding on the upper surface 100a of the concrete.

Here, as shown in FIG. 6, projecting portion 106a2 and welded portion 108 are provided so as to sandwich flange 213a in the Y direction. With such a configuration, it is possible to suppress a difference in bonding strength of welded portion 108 depending on the direction in which leg portion 213 falls.

Further, as shown in FIG. 5, the post-installed anchor 105 is arranged at a position deviated from the fixing plate 106a in the X direction and the opposite direction of the X direction. The post-installed anchor 105 is installed on the peripheral portion of the fixing plate 106a after placing the concrete. As described above, the portion of the post-installed anchor 105 that protrudes above the upper surface 100a of the concrete is the stud bolt 105a.

As shown in FIG. 6, an opening 213a2 is provided in an overhanging portion 213a3 of the flange 213a. The opening 213a2 is, for example, a through hole passing through the flange 213a in the Z direction, but may be a notch.

Then, as shown in FIG. 5, the stud bolt 105a penetrates the opening 213a2 and protrudes to the side opposite to the upper surface 100a of the concrete with respect to the flange 213a, that is, to the upper side of the flange 213a. A nut 107 is tightened to a portion of the stud bolt 105a above the flange 213a. The flange 213a of the leg portion 213, that is, the shelf 210 is fixed to the raft foundation 100 by sandwiching the flange 213a between the nut 107 fastened to the stud bolt 105a and the upper surface 100a. The nut 107 is an example of a fixture and can also be called a fastener.

The post-construction anchors 105 are constructed at predetermined positions around the fixing plate 106a after the raft foundation 100 including the fixing plate 106a is constructed. Then, with the stud bolts 105a protruding above the peripheral upper surface 100a, the flanges 213a of the leg portions 213 are placed on the fixing plate 106a so that the stud bolts 105a pass through the openings 213a2. The inner diameter of opening 213a2 is set to a size that provides a predetermined clearance with respect to the outer diameter of stud bolt 105a so as to absorb misalignment between stud bolt 105a and opening 213a2.

Here, as shown in FIGS. 4 and 5 , the lower end 105b of the post-installed anchor 105 is located above the reinforcing bars 11 and 12 . That is, as the post-installed anchor 105, a relatively short anchor that does not reach the depth where the reinforcing bars 11 and 12 are installed is adopted. As an example, post-installed anchor 105 is a metal-based anchor, such as a metal expansion anchor. With such a configuration, damage to the reinforcing bars 11 and 12 during construction of the post-installed anchor 105 can be avoided.

As shown in FIGS. 4 and 5, a nut 213c is fixed on the central portion of the flange 213a, and a height adjusting bolt 213b extending in the Z direction is engaged with the nut 213c. The nut 213c is integrated with the flange 213a by being welded to the flange 213a, for example. The height adjusting bolt 213b also meshes with a nut (not shown) built in the lower part of the column 212. As shown in FIG. In such a configuration, the height of the leg portion 213 in the Z direction, in other words, the length of the leg portion 213 can be adjusted by turning the height adjustment bolt 213b.

After the reinforced concrete solidifies, post-installed anchors 105 are constructed at predetermined positions on the upper surface 100a of the reinforced concrete (S50). In S50, the post-installed anchor 105 is installed such that the stud bolt 105a protrudes upward from the upper surface 100a.

[Combination of leg and post-installed anchor (S60)]
After S50, the leg portion 213 is placed on the fixing plate 106a with the stud bolt 105a of the post-installed anchor 105 passing through the opening 213a2 of the flange 213a. Then, the nut 107 is tightened to the stud bolt 105a, and the flange 213a is sandwiched between the nut 107 and the upper surface 100a, thereby joining the leg portion 213 and the post-installed anchor 105 (S60).

[Welding of legs and fixing plate (S70)]
After S60, the flange 213a, that is, the leg portion 213 and the fixing plate 106a are welded (S70). By performing S60 before S70, it is possible to obtain the effect of suppressing displacement between the flange 213a and the fixing plate 106a in the welding of S70.
