However, in the seismic control structure of the frame disclosed in Patent Document 1, since the lowest part of the column in the frame is an ultra-soft steel column made of extremely low yield point steel, the frame of a normal column not provided with an ultra-soft steel column There is a problem that the frame strength is reduced.
In other words, it is a frame that originally needs strength against earthquakes, but because the frame is provided with a low-strength part to absorb the energy of a large earthquake, avoiding a decrease in strength of the entire frame. I can't.

(First embodiment)
Hereinafter, the damping structure of the storage shelf according to the first embodiment will be described with reference to the drawings.
This embodiment is an example in which the vibration control structure of the storage shelf is applied to a storage shelf of an automatic warehouse.
As shown in FIG. 1, the automatic warehouse 10 includes a plurality of storage shelves 11, a stacker crane 13 that reciprocates on a rail 12 provided between the storage shelves 11, and a ground control panel C as a control device. ing.
The stacker crane 13 as the article transfer device transports the article W between the storage shelf 11 and the loading / unloading table 14 provided at the end of the storage shelf 11, and also for the rearrangement of the article W in the storage shelf 11. The goods are transported to.
The ground control panel C performs storage management and inventory management of the articles W, and also performs a rearrangement plan of the articles W stored in the storage rack 11, and performs the storage management, inventory management, and the rearrangement planning of the articles W. Is transmitted to the stacker crane 13.
In the present embodiment, the traveling direction of the stacker crane 13 is the longitudinal direction of the storage shelf 11, and the direction in which the article W enters and exits between the stacker crane 13 and the storage shelf 11 is the front-rear direction of the storage shelf 11.
In addition, the weight of many articles | goods W accommodated in the storage shelf 11 is mutually the same.

As shown in FIG. 1, the storage rack 11 and the stacker crane 13 include a storage rack 11, a stacker crane 13, a storage rack 11, a storage rack 11, a stacker crane 13, a storage rack 11, a storage rack 11, a stacker crane 13, and a storage rack. They are arranged in the order of 11.
Each storage shelf 11 has the same configuration.
As shown in FIG. 3, a large number of article storage spaces S for storing articles W are formed in the vertical direction and the longitudinal direction of the storage shelf 11.

As shown in FIGS. 2A, 4, and 5, the storage shelf 11 includes a main frame 15 that is a main skeleton of the storage shelf 11.
The main frame 15 includes a pair of main column members 16 arranged at the front and rear, and a main beam member 17 that connects the top, bottom, and middle of the main column member 16.
The lower end of each main column member 16 is fixed to the floor surface F.
As shown in FIG. 2A, the main frame 15 of the present embodiment is formed with two main frame surfaces 18 surrounded by the main column member 16 and the main beam member 17. A plurality of lattices 19 are arranged in the vertical direction.
The lattice 19 is a vertical diagonal member for preventing deformation of the main structural surface 18, and is inclined with respect to the main column member 16 to connect the front and rear main column members 16.
The main frame 15 is an element mainly responsible for the strength required for the storage shelf 11.
The main column member 16, the main beam member 17, and the lattice 19 are made of steel, and the main column member 16 is a steel pipe.

As shown in FIG. 3, a dependent frame 20 is arranged next to the main frame 15 in the longitudinal direction of the storage shelf 11.
The dependent frame 20 includes a pair of dependent column members 21 arranged at the front and rear, and a dependent beam member 22 that connects the top portion, the lower portion, and the intermediate portion of the dependent column member 21.
The lower end of each dependent column member 21 is fixed to the floor surface F.
As shown in FIG. 2B, the dependent frame 20 is formed with two dependent structural surfaces 23 surrounded by the dependent column member 21 and the dependent beam member 22.
Since the lattice 19 is not disposed on the dependent structural surface 23, the dependent structural surface 23 is easily deformed when subjected to an external force in the front-rear direction as compared with the main structural surface 18.
The dependent frame 20 has a strength that can support the article W, contributes little to the earthquake of the storage rack 11, and has a significantly lower rigidity than the main frame 15.
The dependent column member 21 and the dependent beam member 22 are made of steel, and the dependent column member 21 is a steel pipe having a smaller diameter than the main column member 16.

As shown in FIG. 3, in the storage shelf 11 of this embodiment, the main frame 15 and the sub frame 20 are alternately arranged in the longitudinal direction of the storage shelf 11.
As shown in FIGS. 4 and 5, the main frame 15 includes a substantially U-shaped support member 24 fixed to a pair of main column members 16.
The dependent frame 20 includes a substantially U-shaped support member 25 fixed to a pair of dependent column members 21 so as to face the support member 24.
The support members 24 and 25 are members that support the article W.
Therefore, in this embodiment, the article accommodation space S is a space defined by the support members 24 and 25 between the main frame 15 and the subframe 20.

The storage shelf 11 includes a horizontal frame 26 that connects the main column member 16 on the rear side of the main frame 15 and the sub column member 21 on the rear side of the sub frame 20.
The horizontal frame member 26 is formed of a steel material, and is horizontally laid on the upper, lower and intermediate portions of the main column member 16 and the dependent column member 21.
In addition, the storage shelf 11 includes a horizontal frame member 26 that connects the main column member 16 on the front side of the main frame 15 and the dependent column member 21 on the front side of the sub frame 20.
The two main column members 16 sandwiching the dependent column member 21 between the front and rear portions of the storage shelf 11 and the upper and lower horizontal frames 26 form a vertical plane on the front and rear portions of the storage shelf 11. To do.
As shown in FIG. 3, braces 27 are arranged diagonally on the rear vertical surface.
Both end portions of the brace 27 are connected to locations where the main column member 16 and the horizontal frame 26 intersect each other.
The horizontal frame member 26 and the brace 27 are elements that improve the strength of the storage shelf 11.
In FIG. 4, for convenience of explanation, the main frame 15 in which the support member 24 is not illustrated and the subframe 20 in which the support member 25 is not illustrated, and the brace 27 are not illustrated.

The storage shelf 11 of the present embodiment includes an uppermost part of the main frame 15 and the substructure 20 (the top of the main column member 16 and the subordinate column member 21) and a lower portion of the support members 24 and 25 at the fourth stage from the top (main column). In the middle of the member 16 and the dependent column member 21, an oil damper 28 as a horizontal diagonal member is provided.
The oil damper 28 is installed horizontally between the main frame 15 and the sub frame 20, and is disposed between the front main column member 16 and the rear sub column member 21 or the rear main column member 16. It connects between the dependent column member 21 of the front part.
That is, the oil damper 28 corresponds to a connecting member that connects the main frame 15 and the sub frame 20.
The longitudinal direction of the oil damper 28 is inclined with respect to the longitudinal directions of the main beam member 17 and the dependent beam member 22, that is, inclined with respect to the main structural surface 18 and the dependent structural surface 23.

The oil damper 28 is a vibration damping member that attenuates vibration, and has a structure that can be expanded and contracted in the longitudinal direction by using the oil incorporated in the oil damper 28.
When the compression force and the pulling force during vibration act on the oil damper 28 and the oil damper 28 expands and contracts, the oil built in the oil damper 28 absorbs vibration energy.
As described above, the storage shelf 11 of the present embodiment has a vibration control structure in which the oil damper 28 as a vibration control member is used for the horizontal diagonal member that connects the main frame 15 and the sub frame 20.

Next, the vibration control effect of the storage shelf 11 according to this embodiment will be described.
When a large earthquake occurs, the accommodation shelf 11 is shaken. However, the main frame 15 having sufficient strength and the subframe 20 that is easily deformed compared to the main frame 15 have different phases from each other. Will occur.
The main frame 15 having high rigidity has a small deformation, and the sub frame 20 easily deforms with respect to an external force, resulting in a large deformation.
In particular, the upper part of the storage shelf 11 tends to swing more than the lower part.

A compression force and a pulling force act on the oil damper 28 as the accommodation shelf 11 shakes. However, since the main frame 15 and the subframe 20 are shakes having different phases, the oil damper 28 expands and contracts greatly.
As the oil damper 28 expands and contracts greatly, the oil built in the oil damper 28 efficiently absorbs seismic energy.
The oil damper 28 efficiently absorbs seismic energy, so that the shaking in the storage shelf 11 is suppressed.
In the vibration control structure of the storage rack 11 according to the present embodiment, the amount of displacement, response acceleration, and main acceleration due to shaking at the top of the storage rack 11 when a large earthquake occurs is compared with a conventional storage rack using horizontal diagonal materials as steel. The shear force acting on the frame 15 is reduced to about half.

Since the oil damper 28 is used as a horizontal diagonal member, when horizontal shaking (rolling) occurs, the oil damper 28 absorbs seismic energy regardless of the direction of rolling.
6 (a) to 6 (c) are plan views of the main part of the uppermost part of the storage shelf 11, and schematically show the vibration control action for rolling in different directions. Besides showing the direction of shaking, the solid line shows the state before deformation, and the two-dot chain line shows the state after deformation.
6A shows a case where the storage shelf 11 rolls in the front-rear direction, FIG. 6B shows a case where the storage shelf 11 rolls in the longitudinal direction, and FIG. Is a case where it rolls at an inclination of 45 degrees with respect to the longitudinal direction.
In FIG. 6A to FIG. 6C, for convenience of explanation, one of two oil dampers 28 having different inclination directions is an oil damper 28A and the other is an oil damper 28B.

In FIG. 6 (a), the subordinate frame 20 is deformed in the front-rear direction due to the rolling of the storage shelf 11 in the front-rear direction.
The oil dampers 28 </ b> A and 28 </ b> B expand and contract with the deformation of the dependent frame 20.
When the substructure 20 is deformed so as to incline forward from the initial position, a compression force acts on the oil dampers 28A, 28B, and when the subframe 20 is deformed to incline backward from the initial position, the oil dampers 28A, 28B. A pulling force acts on.

In FIG. 6 (b), the rolling in the longitudinal direction of the storage shelf 11 is shown.
In the rear part of the storage shelf 11, the two main pillar members 16 sandwiching the dependent column member 21 and the upper and lower horizontal members 26 form a vertical surface on the rear part of the storage shelf 11, and the vertical structure of the rear part. A brace 27 is arranged on the surface.
In the roll in the longitudinal direction of the storage shelf 11, the rear vertical structural surface functions as a main structural surface, and the front vertical structural surface without the brace 27 facing the rear vertical structural surface functions as a dependent structural surface. .
For this reason, the frame that forms the front vertical structure is greatly deformed compared to the frame that forms the rear vertical structure, and the rear vertical structure and the front vertical structure have different phases. .
The oil dampers 28A and 28B expand and contract with the deformation of the frame that forms the front vertical structure, but the frame that forms the front vertical structure deforms from the initial position toward one side (upper side in the figure). A compressive force acts on the oil damper 28A, and a tensile force acts on the oil damper 28B.
When the frame that forms the front vertical structural surface is deformed from the initial position toward the other side (lower side in the figure), a tensile force acts on the oil damper 28A, and a compressive force acts on the oil damper 28B. .

In FIG. 6 (c), as shown by the arrow, the rolling is inclined 45 degrees with respect to the longitudinal direction, and therefore the subordinate frame 20 is deformed toward the rolling direction.
When the dependent frame 20 is deformed so as to be inclined obliquely forward from the initial position, a compression force acts on the oil damper 28A, and a slight pulling force acts on the oil damper 28B.
When the subframe 20 is deformed so as to be inclined obliquely backward from the initial position, a tensile force acts on the oil dampers 28A and 28B, but the tensile force acting on the oil damper 28B is compared with the tensile force of the oil damper 28A. There are few.
6A to 6C, the oil dampers 28A and 28B absorb seismic energy when compressive force and tensile force are applied.

The vibration control structure of the storage shelf according to the present embodiment has the following effects.
(1) Even if the storage shelf 11 receives earthquake energy, the main frame 15 and the sub frame 20 are deformed, but the sub frame 20 without the lattice 19 is greatly deformed compared to the main frame 15 with the lattice 19. The main frame 15 and the sub frame 20 cause different phase fluctuations. The oil damper 28 connecting the main frame 15 and the sub frame 20 absorbs the seismic energy and attenuates the shaking of the storage rack 11. In the present embodiment, since the vibration control member is not provided in the main frame 15, the strength of the main frame 15 is improved as compared with the case where the vibration control member is provided in the main frame 15, and sufficient vibration control performance is provided to the storage shelf 11. It can be demonstrated. As a result, the strength burden on the main frame 15 can be reduced as compared with the conventional case.
(2) Since the horizontal diagonal material is the oil damper 28, the oil damper 28 can efficiently absorb the seismic energy acting on the storage rack 11 regardless of the roll direction. Further, since the oil damper 28 can be restored to the compressive force and the tensile force, the oil damper 28 can efficiently absorb and dampen the vibration caused by the earthquake in the storage shelf 11 and can be used repeatedly. Can do.

(3) Since the oil damper 28 is provided at the uppermost part of the storage shelf 11 and the lower part of the support members 24 and 25 in the fourth stage from the top, the oil damper 28 is located at the upper part where the shaking is larger than the lower part of the storage shelf 11. The vibration can be attenuated efficiently. Accordingly, when compared with a conventional storage rack made of horizontal diagonal steel, the amount of displacement due to shaking at the top of the storage rack 11, the response acceleration, and the shear force applied to the main frame 15 are reduced by about half when a large earthquake occurs. can do. As a result, even if a large earthquake occurs while the articles W are stored in the storage racks 11, the articles W can be prevented from falling from the storage racks 11. It is preferable to provide the oil damper 28 on the upper portion of the storage shelf 11 that is at least half the height of the storage shelf 11.
(4) Even if it is an existing storage shelf, the vibration control function can be added to the existing storage shelf by replacing the horizontal diagonal member connecting the main frame and the subordinate frame with the oil damper 28. Moreover, since it is only replaced | exchanged for the oil damper 28, the conversion from the existing storage shelf to the storage shelf provided with the vibration control function is easy. Since the storage shelves are assembled on site, replacement to the oil damper 28 itself is easy.

( Reference example )
Next, the damping structure of the storage shelf according to the reference example will be described.
The reference example is different from the first embodiment in that a horizontal diagonal member connecting the main frame and the sub frame is made of steel, and an oil damper is provided on the sub frame.
About another structure, it is the same structure as 1st Embodiment, About the same structure, description of 1st Embodiment is used and a code | symbol is used in common.

As shown in FIG. 7, the storage shelf 31 includes a connecting member 32 as a horizontal diagonal member that connects the main frame 15 and the subframe 20.
In the present embodiment, the connecting member 32 is formed of a steel material.
A pair of oil dampers 33 connecting the front and rear dependent column members 21 are diagonally installed on the dependent structural surface 23 of the dependent frame 20.
The pair of oil dampers 33 is installed for each subordinate structural surface 23, and the basic structure is the same as that of the oil damper 28 of the first embodiment.

In the event of a major earthquake, when the substructure 20 is deformed in the front-rear direction so that the subsurface 23 is converted into a parallelogram due to the seismic energy, each oil damper 33 has a compressive force or A tensile force acts and the oil damper 33 expands and contracts greatly.
The oil damper 33 that expands and contracts greatly absorbs seismic energy efficiently.
According to this embodiment, the oil damper 33 installed in the subordinate frame 20 can attenuate the roll in the front-rear direction of the storage shelf 11.
Since the roll in the front-rear direction can be attenuated, even if a large earthquake occurs in the state where the article W is stored in the storage shelf 31, the article W can be prevented from falling forward from the storage shelf 11. it can.
Further, since the pair of oil dampers 33 are arranged on the subordinate structural surface 23, the amount of contraction of the oil damper 33 due to compression and tension when the subordinate frame 20 is deformed can be increased, and the seismic energy can be absorbed efficiently. can do.

(Second Embodiment)
Next, the vibration control structure of the storage shelf according to the second embodiment will be described.
The second embodiment is different from the first embodiment in that the horizontal diagonal member connecting the main frame and the sub frame is a low yield point steel material.
About another structure, it is the same structure as 1st Embodiment, About the same structure, description of 1st Embodiment is used and a code | symbol is used in common.

As shown in FIG. 8, the storage shelf 41 includes a pair of connecting members 42 as horizontal diagonal members that connect the main frame 15 and the subframe 20.
In the present embodiment, the pair of connecting members 42 connect the front and rear main column members 16 and the dependent column members 21 diagonally.
The connecting member 42 is formed from a low yield point steel material.
The low yield point steel is a steel having a low strength and a very high ductility compared to mild steel.

When a large earthquake occurs, the accommodation shelf 41 is shaken, and the main frame 15 and the subframe 20 are shaken in different phases.
A compression force and a pulling force act on the connecting member 42 as the accommodation shelf 41 shakes. However, since the main frame 15 and the sub frame 20 have different phases, the connecting member 42 made of low yield point steel is Deforms greatly in response to tension.
When the connecting member 42 is greatly deformed, the seismic energy is absorbed. When the connecting member 42 absorbs the seismic energy, the shaking in the storage shelf 41 is attenuated.

According to the present embodiment, since the pair of connecting members 42 are used as horizontal diagonal members, when horizontal shaking (rolling) occurs, the connecting member 42 is connected regardless of the direction of rolling. The deformation of the member 42 can absorb seismic energy.
The deformed connecting member 42 may be replaced with a new connecting member 42.

( Third embodiment)
Next, the vibration control structure of the storage shelf according to the third embodiment will be described.

In the present embodiment, when vibration in the front-rear direction in which the dependent frame 20 moves relative to the main frame 15 in the front-rear direction (swing parallel to the main structural surface 18 and the dependent structural surface 23) occurs, The two members 64 move relative to each other.
As shown in FIG. 10, the damper 68 is deformed in the front-rear direction in accordance with the relative movement between the connecting member 65 and the second member 64.
Therefore, since the direction of vibration in the storage shelf 61 and the direction of deformation of the damper 68 coincide with each other, the vibration in the front-rear direction is efficiently attenuated and the vibration energy is absorbed by the damper 68.

In the present embodiment, in addition to the uppermost part of the subordinate frame 20, a connecting member 62 including a damper 68 is provided on the subordinate beam member 22 that is the lower part of the support member 25 in the fourth stage from the top.
The space between the support member 25 at the fourth stage from the top and the subordinate beam member 22 which is the lower part of the support member 25 is a space where the articles W and the fork of the stacker crane 13 do not exist.
On the other hand, in a space where the fork of the article W or the stacker crane 13 may be present, there is a first member 63 formed of the same steel material as that of a conventional horizontal diagonal member.
For this reason, even when the height dimension of the damper 68 is large, the space in which the article W and the fork of the stacker crane 13 may be present is not adversely affected by the reduction in accommodation efficiency due to the installation of the damper 68. .

According to the storage shelf 61 of this embodiment, there exist the following effects.
(5) The storage shelf 61 receives seismic energy, and the main frame 15 and the subframe 20 may cause different phase fluctuations in the front-rear direction. In this case, the damper 68 provided on the connecting member 62 that connects the main frame 15 and the subframe 20 is deformed in the same front-rear direction as the direction of the vibration to efficiently absorb the seismic energy, and the vibration of the storage shelf 61 in the front-rear direction Can be effectively attenuated. Further, in this embodiment, since the main frame 15 is not provided with a vibration damping member, the strength of the main frame 15 is improved as compared with the case where the main frame 15 is provided with a vibration damping member, and sufficient vibration control is applied to the storage shelf 61. Performance can be demonstrated. As a result, the strength burden on the main frame 15 can be reduced as compared with the conventional case.
(6) Since the damper 68 is a rubber damper, the manufacturing cost can be suppressed, and maintenance of the damper 68 is easier than the oil damper 28. Further, since the damper 68 can be restored to the compressive force and the tensile force, the damper 68 can efficiently absorb and attenuate the vibration caused by the earthquake in the storage shelf 61, and the damper 68 can be used repeatedly. .

(7) Since the connecting member 62 provided with the damper 68 is provided at the uppermost part of the storage shelf 61 and the lower part of the support members 24 and 25 in the fourth stage from the top, the damper 68 sways compared to the lower part of the storage shelf 61. It is possible to efficiently attenuate the shaking at the upper part where is large. Therefore, when compared with a conventional storage rack made of steel made of horizontal diagonal, the amount of displacement due to shaking at the top of the storage rack 61, the response acceleration, and the shear force received by the main frame 15 are reduced by about half when a large earthquake occurs. can do. As a result, even if a large earthquake occurs while the articles W are stored in the storage rack 61, the articles W can be prevented from falling from the storage rack 61. It is preferable to provide the connection member 62 provided with the damper 68 on the upper part of the storage shelf 11 which becomes more than half of the height of the storage shelf 61.
(8) Even if it is an existing storage shelf, the horizontal diagonal member connecting the main frame 15 and the subframe 20 is replaced with a connecting member 62 having a damper 68, so that the existing storage shelf has a vibration control function. Can be added. Moreover, since it is only replaced | exchanged for the connection member 62 provided with the damper 68, the conversion from the existing storage shelf to the storage shelf 61 provided with the vibration control function is easy. Since the storage shelf 61 is assembled at the site, the replacement work itself to the connecting member 62 provided with the damper 68 is easy.

(9) The damper 68 is provided in a space where the articles W and the fork of the stacker crane 13 do not exist. On the other hand, in the space where the articles W and the fork of the stacker crane 13 may exist, A first member 63 made of the same steel as the material is provided. For this reason, even when the height dimension of the damper 68 is large, the space in which the article W and the fork of the stacker crane 13 may be present is not adversely affected by the reduction in accommodation efficiency due to the installation of the damper 68. . As a result, when the storage shelf having the main structural surface 18 and the dependent structural surface 23 and having no vibration control function is modified to be the storage shelf 61 of the present embodiment, the connecting member 62 having the damper 68 from the horizontal diagonal member. All you need to do is replace it.

As shown in FIGS. 12 and 13, braces 27 are arranged diagonally on the vertical vertical surface of the storage shelf 81.
Both end portions of the brace 27 are connected to locations where the main column member 16 and the horizontal frame 26 intersect each other.
Note that the brace 27 is not provided on the front vertical construction surface of the storage shelf 81 because the article W is put in and out of the article storage space S by the stacker crane 13.
The horizontal frame member 26 and the brace 27 are elements that improve the strength of the storage shelf 81.

In the present embodiment, as shown in FIG. 13, a connection member 62 that connects between the main frame 15 and the subframe 20 is provided at the uppermost portion of the storage shelf 81.
The first member 63 of the connecting member 62 is fixed to the slave beam member 22, and the second member 64 is fixed to the main column member 16.
The connecting member 62 includes a damper 68 and has the same structure as the connecting member 62 of the third embodiment.
Accordingly, the damper 68 can be deformed in the same direction as the vibration in the front-rear direction of the storage shelf 81.
In the present embodiment, in addition to the uppermost part of the storage shelf 81, the connecting member 62 including the damper 68 is provided between the main frame 15 and the subframe 20 in the middle part (second stage, fourth stage, and eighth stage). Link.
In FIG. 12, the location of the connecting member 62 including the damper 68 is indicated by a dotted line.

On the other hand, in the uppermost part of the storage shelf 81, a horizontal diagonal member 82 is provided for connecting between the subordinate frames 20 provided in series.
The horizontal diagonal member 82 is a connecting member that does not include the damper 68 and has the same configuration as the connecting member 32 of the reference example .
In the present embodiment, in addition to the uppermost part of the storage shelf 81, the intermediate diagonals (second stage, fourth stage, sixth stage, and eighth stage) connect the horizontal diagonal members 82 between the adjacent frames 20 adjacent to each other. To do.
In addition, in FIG. 13, the site | part of the upper part from the article | item storage space S of the 6th step | paragraph of the storage shelf 81 is expanded and shown in figure.

In the storage shelf 81 of this embodiment, when the shelf usage rate is 80% (the number of articles is 48), articles W are arranged as shown in FIG.
A large number of articles W are accommodated in the first frame space S1 in the storage shelf 81 to form a heavy load zone HZ, and a small load zone LZ is accommodated in the second frame space S2 with less articles W than the large load zone HZ. Forming.
Since the subordinate frame 20 constituting the first frame space R1 in the large load zone HZ contains many articles W, it receives a large load.
On the other hand, since the main frame 15 constituting the second frame space R2 in the small load zone LZ contains a small number of articles W, the main frame 15 receives a load smaller than the load received by the dependent frame 20 in the large load zone HZ.

Specifically, the articles W are all accommodated in the two first frame spaces R1 of the accommodation shelf 81 to form the large load zone HZ.
Further, in the four second frame spaces R2 of the storage shelf 81, the articles W are stored from the lowest level to the seventh level of the article storage space S, and the 8th to 10th levels of the article storage space S are emptied, whereby a small load Zone LZ is formed.

In the state in which the article W is accommodated so that the large load zone HZ and the small load zone LZ are formed in the accommodation shelf 81, the dependent column member 21 in the dependent frame 20 adjacent to the main frame 15 is the large load zone. A large load from the article W on the HZ side and a small load from the article W on the small load zone LZ side are received.
In other words, the dependent column member 21 in the dependent frame 20 adjacent to the main frame 15 receives a large load from the large load zone HZ side and applies a small load compared to the large load zone HZ side to the small load zone LZ side. Receive from.
In the present embodiment, load loads received by the dependent column members 21 in the pair of dependent frames 20 forming the first frame space R1 are symmetrical with each other in FIG.

When a large earthquake occurs, the accommodation shelf 81 will sway, but a case will be described in which the product W sways in the front-rear direction.
As shown in FIG. 14, when a shaking occurs in the front-rear direction due to a large earthquake, the second frame space R2 forming the small load zone LZ and the first frame space R1 forming the large load zone HZ are shown in FIG. Cause shaking with different phases.
In addition to the structural characteristics of the storage shelf 81 in which the dependent frame 20 swings with a longer period than the main frame 15, the large load zone HZ and the small load zone LZ are formed by the arrangement of the articles W. Becomes a large deformation compared to the small load zone LZ.
That is, the swing in the small load zone LZ is a swing with a small cycle, and the swing in the large load zone HZ is a swing with a large cycle.
In particular, the upper part of the storage shelf 81 tends to be more swayed than the lower part.
In FIG. 14, the swing of the main frame 15 with a small swing is not shown, and the swing of the substructure 20 with a large swing is illustrated.

A compression force or a pulling force acts on the damper 68 of the connecting member 62 in accordance with the shaking of the storage shelf 81. However, since the large load zone HZ and the small load zone LZ are in different phases, the damper 68 is large. It expands and contracts.
As the damper 68 expands and contracts greatly, the earthquake energy is efficiently absorbed.
As the damper 68 efficiently absorbs the seismic energy, shaking in the storage shelf 81 is suppressed.

Note that the article W may be loaded and unloaded from a state in which the large load zone HZ and the small load zone LZ are formed on the storage shelf 81.
At this time, an empty article storage space S is generated in the large load zone HZ due to the loading / unloading of the articles W, or the article W is stored in the empty article storage space S of the small load zone LZ. The small load zone LZ may be eliminated.
In the present embodiment, even if the heavy load zone HZ and the small load zone LZ are eliminated, the ground control panel C performs storage management and inventory management of the articles W, and also stores the articles W stored in the storage rack 81. Make a relocation plan.
The rearrangement plan is a plan related to the arrangement of the articles W for forming appropriate large load zones HZ and small load zones LZ.
The ground control panel C transmits a command for executing the rearrangement plan of the article W to the stacker crane 13, and the stacker crane 13 moves the article W in response to the command.
By the movement of the article W of the stacker crane 13, the large load zone HZ and the small load zone LZ are formed in the storage shelf 81 again.

The storage shelf 81 according to this embodiment has the following operational effects.
(10) When an earthquake occurs and swings in the front-rear direction (the direction in which the article W is put in and out), the swing in the heavy load zone HZ becomes larger and the swing in the small load zone LZ becomes smaller than the swing in the heavy load zone HZ. The large load zone HZ and the small load zone LZ have different phases. At this time, the damper 68 of the connecting member 62 that connects the substructure 20 positioned between the heavy load zone HZ and the small load zone LZ and the main frame 15 adjacent to the substructure 20 absorbs the seismic energy. Then, the shaking of the storage shelf 81 is attenuated. In the storage rack 81 having a vibration control function by the main frame 15 and the subframe 20, the vibration control performance of the storage rack 81 is further improved by forming the large load zone HZ and the small load zone LZ by arranging the articles W. Can do.
(11) It is not necessary to provide the damper 68 between the subordinate frames 20 adjacent to each other, and the damper used for the storage shelf 81 can be reduced as compared with the first embodiment. As a result, the manufacturing cost of the storage shelf 81 can be suppressed.

(12) When the empty article storage space S is formed above the second frame space R2, the center of gravity of the storage shelf 81 forms the empty article storage space S below the second frame space S2. In comparison, the stability of the storage rack 81 is improved.
(13) Since all the articles W are accommodated in the article accommodating space S in the first frame space R1 in the large load zone HZ, the swing of the large load zone HZ is larger than that of the small load zone LZ in the event of an earthquake. can do. Seismic energy can be efficiently absorbed by the damper 68 by increasing the difference between the swing of the small load zone LZ and the large load zone HZ.
(14) A stacker crane 13 that takes in and out the article W from and into the article storage space S and transfers the article W, and a ground control panel that controls the transfer of the article W so as to form the large load zone HZ and the small load zone LZ. C. For this reason, even if the goods W of the storage shelf 81 are loaded and unloaded and the large load zone HZ and the small load zone LZ are eliminated, the stacker crane 13 and the ground control panel C cause the large load zone HZ and the small load zone. LZ can be formed again.

(Modification Examples 1 and 2)
Next, modified examples 1 and 2 of the fourth embodiment will be described.
Modifications 1 and 2 are examples of the storage shelf 81 in which the first frame space R1 between the subordinate frames 20 is triple.
The first modification example is an example in which the first frame space R1 excluding the central first frame space R1 in the first frame space R1 is a heavy load zone HZ and the central first frame space R1 is a small load zone LZ. .
The modification example 2 is an example in which all the first frame spaces R1 are the heavy load zones HZ.
The storage shelves 81 of Modification 1 and Modification 2 are different from the fourth embodiment in that they have 50 article storage spaces S, but the configurations of the main frame 15 and the subframe 20 are the same. Used in common.

In the first modification, as shown in FIG. 15, the storage shelf 81 has a structure in which the main frame 15, the subordinate frame 20, the subordinate frame 20, the subordinate frame 20, the subordinate frame 20, and the main frame 15 are sequentially arranged. .
In the storage shelf 81, the first frame space R1 is defined between the subordinate frames 20 adjacent to each other, and the second frame space R2 is defined between the main frame 15 and the subordinate frame 20, and the storage shelf 81 includes three first frame spaces R1. And two second frame spaces R2.
In the first modification, only the first frame space R1 adjacent to the second frame space R2 is set as the heavy load zone HZ.
In addition to setting the second frame space R2 as the small load zone LZ, the first frame space R1 sandwiched between the first frame space R1 is set as the small load zone LZ similarly to the second frame space R2. .
In FIG. 15, 41 articles W are arranged so that the shelf usage rate is 82%.

In the first modification, the load load received by the dependent column member 21 in the dependent frame 20 adjacent to the main frame 15 and the load load of the dependent column member 21 of the dependent frame 20 adjacent to the dependent frame 20 are mutually different in FIG. It becomes symmetrical.
In the first modification, the horizontal diagonal member 82 without the damper 68 can be provided between the dependent frames 20, and the damper 68 only needs to be provided on the connecting member 62 that connects the main frame 15 and the dependent frame 20. For this reason, the number of dampers 68 can be further reduced.
In FIG. 15, a portion where the connecting member 62 including the damper 68 is provided is indicated by a dotted line.

In the second modification, as shown in FIG. 16, as in the first modification, the storage shelf 81 includes a main frame 15, a subframe 20, a subframe 20, a subframe 20, a subframe 20, and a main frame 15 in order. It has a structure.
In the storage shelf 81, the first frame space R1 is defined between the subordinate frames 20 adjacent to each other, and the second frame space R2 is defined between the main frame 15 and the subordinate frame 20, and the storage shelf 81 includes three first frame spaces R1. And two second frame spaces R2.
In the second modification, all the first frame spaces R1 are set as the heavy load zones HZ, and the second frame spaces are set as the small load zones LZ.
In FIG. 16, 40 articles W are arranged so that the shelf usage rate is 80%.

In the second modification, by setting all the first frame spaces R1 as the heavy load zones HZ, the load burden received by the dependent column member 21 of the dependent frame 20 adjacent to the main frame 15 is increased on the large load zone HZ side. It bears the load and the load on the small load zone LZ side.
On the other hand, the load load received by the dependent column member 21 of the dependent frame 20 adjacent to the dependent frame 20 bears the load on the large load zone HZ side on both sides.
That is, the load burden of the dependent column member 21 of the dependent frame 20 adjacent to the main frame 15 and the load load of the dependent column member 21 of the dependent frame 20 not adjacent to the main frame 15 are different.
Therefore, in the second modification, a connecting member 62 having a damper 68 is required between the dependent column member 21 in the dependent frame 20 adjacent to the main frame 15 and the dependent frame 20 adjacent to the dependent frame 20.
The dependent column members 21 of the dependent frame 20 that are not adjacent to the main frame 15 and are adjacent to each other are responsible for the loads on the heavy load zones HZ side on both sides and have the same load burden. .
For this reason, the horizontal diagonal member 82 without the damper 68 can be provided only between the sub-frames 20 not adjacent to the main frame 15.
In addition, in FIG. 16, the location where the connection member 62 provided with the damper 68 is provided is shown by a dotted line.

  In the second modification, the number of dampers 68 cannot be reduced as compared with the first modification, but the horizontal diagonal member 82 without the dampers 68 can be provided between the specific substructures 20. The number of dampers 68 can be reduced as compared with the storage shelves 20 alternately arranged.

  The present invention is not limited to the above-described embodiment, and various modifications are possible within the scope of the gist of the invention. For example, the following modifications may be made.

In the above-described embodiment, the vibration control structure of the storage shelf of the present invention is applied to the storage shelf in the automatic warehouse, but a storage shelf other than the automatic warehouse may be used.
In the above embodiment, the main frame and the sub frame are alternately arranged in the longitudinal direction of the storage shelf, but the arrangement of the main frame and the sub frame is not limited to this. For example, it may be a storage shelf in which two or more subordinate frames are connected like a main frame, a subordinate frame, a subordinate frame, and a main frame. In this case, the horizontal diagonal connecting the main frame and the subordinate frame is a damping member. The horizontal diagonal members connecting the subordinate frames may be steel. Moreover, the storage shelf of the arrangement | sequence which 2 or more main frames continue may be sufficient.
In the above embodiment, the main frame is a main frame formed by being surrounded by the main column member and the main beam member, and the sub frame is a sub frame having the sub column member and the sub beam member. This is not the case. For example, the main structural surface may be formed by a main column member, and the dependent structural surface may be formed by a dependent column member as well. In this case, the support member that supports the article may have a function of a main beam member or a subordinate beam member. Or the connection material between shelves which connects accommodation shelves in the uppermost part may fulfill | perform the function of a main beam member or a subordinate beam member.
In the first and second embodiments described above, the horizontal diagonal member is the vibration damping member. However, the horizontal diagonal member may be provided with a vibration damping member in part. For example, brackets may be provided at both ends of the oil damper, and the oil damper may be fixed to the storage shelf via the bracket. Moreover, you may form a part of connection member with a low yield point steel material.
In the first embodiment, the oil damper is used as the damper. However, for example, a viscoelastic damper may be used instead of the oil damper. When the damper is a viscoelastic damper, vibration can be damped by shearing the rubber-based material. In this case, the same effect as the oil damper is achieved.
○ In the first embodiment described above, the oil damper, which is a damping member, is provided at the uppermost part of the storage shelf and the lower part of the support member at the fourth stage from the top (middle of the main pillar member and the dependent pillar member). However, the installation position of the damping member is not limited to this. The installation location of the damping member is free. In an earthquake, the vibration tends to increase toward the upper part of the storage shelf. Therefore, it is preferable to provide a damping member at the upper part of the storage shelf.
In the first embodiment, the vibration damping members are provided on all the horizontal diagonal members. However, the vibration damping members may be provided on only some of the horizontal diagonal members, and the remaining horizontal diagonal members may be steel materials. In this case, the number of damping members can be reduced as compared with the first embodiment. Moreover, you may make it arrange | position a damping member like the reference example in the subordinate structure in the storage shelf of 1st Embodiment.
In the above reference example , the vibration damping members are provided on the subordinate structures of all the subordinate frames. However, vibration control members may be provided on some of the subordinate structures. In this case, the number of damping members can be reduced as compared with the reference example .
In the above reference example , a pair of oil dampers are arranged diagonally on the subordinate structure of the subordinate frame. However, for example, as shown in the modified example shown in FIG. 17, the oil damper 51 is installed on the subordinate structure 23 of the subordinate frame 20. You may make it arrange | position in zigzag similarly to the lattice provided in the main structure surface of the main frame. In this case, the same effect as the reference example can be expected.
In the above reference example , the pair of oil dampers are arranged diagonally on the subordinate structural surface of the subordinate frame. However, for example, oil dampers 33A and 33B may be installed as in the modified example shown in FIG. The basic structure of the oil dampers 33A and 33B shown in FIG. 18 is the same as that of the oil damper 33 of the reference example . In FIG. 18, the oil dampers 33 </ b> A and 33 </ b> B are installed so as to intersect with the middle position between the uppermost horizontal frame member 26 and the intermediate horizontal frame member 26 in the height direction of the dependent column member 21. That is, a pair of oil dampers 33 </ b> A and 33 </ b> B connecting the front and rear dependent column members 21 are diagonally installed on the upper half and the lower half of the dependent structural surface 23 of the dependent frame 20. When a large earthquake occurs, for example, the substructure 20 is bent so that the vicinity of the middle of the substructure 23 in the vertical direction (between the uppermost horizontal frame 26 and the middle horizontal frame 26) is greatly curved by the seismic energy. Is deformed in the front-rear direction, a compressive force or a pulling force acts on each of the oil dampers 33A, 33B as the dependent frame 20 is deformed, and the oil dampers 33A, 33B expand and contract greatly. The oil dampers 33A and 33B that expand and contract greatly absorb seismic energy efficiently. Note that it is possible to install only the lower oil damper 33A without installing the upper oil damper 33B in FIG. In addition, the oil damper 33A (and the oil damper 33B) may be installed also on the subordinate construction surface 23 that becomes the intermediate horizontal member 26 and the lower horizontal member 26 in the storage shelf 31.
○ In the above embodiment, a steel pipe with a small diameter is used so that the cross-sectional area of the subordinate column member is smaller than the cross-sectional area of the main column member. However, the setting of the subordinate frame is not limited to this. For example, instead of reducing the diameter of the dependent column member, the diameter is the same so that the cross-sectional areas of the main column member and the dependent column member are the same, and the member thickness (plate thickness) of the steel pipe of the dependent column member is the main thickness. It is good also as a setting which sets smaller than the member thickness (plate | board thickness) of the steel pipe of a column member, and makes a subordinate frame deform | transform easily than a main frame. Further, in the case where the sub frame can be set to be more easily deformed than the main frame, it is not disturbed that the lattice is provided on the sub surface like the main frame.
In the above embodiment, the distance between the main column members before and after the main frame and the distance between the sub column members of the sub frame are set to the same distance, but this is not restrictive. For example, as shown in FIG. 19, a dependent frame 200 in which the distance between the dependent column members 21 is set shorter than the distance between the main column members 16 in the main frame 15, and the dependent frame 200 is more easily deformed than the main frame 15. You may make it do. In this case, even if the main column member 16 and the dependent column member 21 have the same dimensions, the dependent frame 200 is more easily deformed than the main frame 15.
In the above third and fourth embodiments (including modified examples), the damper is a rubber damper that deforms in the front-rear direction, but is not limited to a rubber damper. The damper may be, for example, an oil damper that can extend and contract in the Australian direction. In this case, the oil damper performs the same function as the rubber damper.
