  2. Description of the Related Art Conventionally, there is known an automatic warehouse in which a stacker crane is run between multi-stage high-rise racks (shelves) to automate loading and unloading operations. The rack of an automatic warehouse is a high-rise structure erected on a support base such as a floor.

  When an earthquake occurs, the top of the rack is swung with maximum amplitude. The gap between adjacent racks is narrow enough to allow the stacker crane to travel, so the racks may collide and interfere with each other, such as when the phase of the rack vibration period is different and the maximum amplitude is large. Since there is a possibility of falling from the rack, it is preferable to dampen the rack.

  In the case of damping the rack, it is possible to apply the above-described background art, but it is preferable that the rack is rationally, simply, and effectively damped without disturbing the travel of the stacker crane. And of course, if it is a damping structure applicable to structures, such as this kind of rack, it is applicable to a general building, and the creation of such a damping structure was desired.

  The present invention has been made in view of the above-described conventional problems, and provides a structure damping structure capable of damping a structure such as a rack rationally, simply, and effectively. With the goal.

  The vibration damping structure of the structure according to the present invention is the same as the fixed side structure constructed by being fixed on the support base, and has the same height as the fixed side structure. Both ends of the movable side structure that is supported so as to be horizontally movable in the direction of contact with and away from the fixed side structure via the direction movable means, and the top of the movable side structure and the top of the fixed side structure Rigidly joined and provided horizontally only in the horizontal movement direction of the movable side structure only between the top of the movable side structure and the top of the fixed side structure, and the movable side structure and the fixed side A rigid connecting member that transmits force to and from the side structure, and the support structure is supported by any one of the pair of existing structures constructed by being fixed on the support base. Separated from the base and is brought into contact with or separated from the other existing structure on the support base through the horizontal moving means. Supported horizontally movably in the direction, the a movable structure, characterized in that the other one of the existing structure and the fixed side structure.

  An elastic means is provided between the movable side structure and the support base for elastically biasing the movable side structure that is horizontally moved.

  Attenuating means for attenuating the moving force of the movable side structure that is moved horizontally is provided between the movable side structure and the support base.

  At least one of the fixed side structure and the movable side structure is provided with a seismic element in a plane orthogonal to the moving direction of the movable side structure.

  The rigid connecting member is provided with a damping member that attenuates a force transmitted to the rigid connecting member.

  The rigidity of the fixed side structure is set larger than the rigidity of the movable side structure.

  The fixed-side structure is seismically isolated on the support base instead of being fixed.

  In order to allow mutual sliding movement between at least one of the fixed-side structure and the movable-side structure and the end of the rigid connecting member, it is orthogonal to the moving direction of the movable-side structure. A sliding mechanism is provided in the direction of moving.

  In the structure damping structure according to the present invention, a structure such as a rack can be effectively and reasonably damped. Specifically, the present invention can be applied not only to a structure such as a new building but also to an existing structure. In this case, of the pair of existing structures constructed by being fixed on the support base, either one of the existing structures is separated from the support base and is placed on the support base via the horizontal moving means. The movable side structure is supported by being movable in the horizontal direction in the direction of contact with or separating from the other existing structure, and the other existing structure may be used as the fixed side structure.

  Preferred embodiments of a structure damping structure according to the present invention will be described below in detail with reference to the accompanying drawings. 1A and 1B are explanatory views for explaining a first embodiment of a structure damping structure 1 according to the present invention, in which FIG. 1A is a front view, FIG. 1B is a plan view, FIG. 1 (c) is a side view, and FIG. 2 is an explanatory view for explaining a vibration model equivalent to the first embodiment shown in FIG. In this embodiment, the rack 2 of an automatic warehouse will be exemplified as a structure and will be described below.

  As shown in FIG. 1, a plurality of racks 2 and 3 are installed in an automatic warehouse. The racks 2 and 3 are constructed in a multi-stage high-rise on the floor 4 of the automatic warehouse as a support base. The heights of the racks 2 and 3 are set to be the same. The planar shapes of the racks 2 and 3 are usually elongated with a large aspect ratio. The gap between the adjacent racks 2 and 3 is set so narrow that the stacker crane can travel.

  Each rack 2, 3 is sealed at both ends in the long longitudinal direction (the direction of arrow A in FIG. 1B) with a lattice (not shown). One side surface of each rack 2, 3 in the left-right width direction (in the direction of arrow B in FIG. 1B) faces the traveling stacker crane side and serves as receiving side surfaces 2 a, 3 a. The other side surfaces of the racks 2 and 3 in the left-right width direction are sealed with a lattice (not shown) to form non-receiving surfaces 2b and 3b. A pair of adjacent racks 2 and 3 are installed such that the receiving side surfaces 2a and 3a on which the stacker crane travels face each other.

  The structure damping structure 1 according to the first embodiment is constructed by fixing one rack 2 (hereinafter referred to as a fixed rack) to a floor 4 for a pair of adjacent racks 2 and 3. .

  The other rack 3 (hereinafter referred to as a movable side rack) approaches the fixed side rack 2 with respect to the floor 4 via horizontal movable means 5 provided between the floor 4 and the lower end 3c of the movable side rack 3. It is constructed by being supported so as to be horizontally movable in the direction of separation or separation (arrow B direction). That is, the movable side rack 3 is supported on the floor 4 so as to be horizontally movable with respect to the fixed side rack 2 in a direction in which the receiving side surfaces 2a and 3a come in contact with and away from each other. The horizontal direction moving means 5 includes a roller bearing, a slide bearing, and a sliding bearing.

  Only between the top 3d of the movable side rack 3 and the top 2d of the fixed side rack 2 is provided a rigid connecting member 6 that transmits force between the movable side rack 3 and the fixed side rack 2, and this rigid connection is provided. The movable rack 3 and the fixed rack 2 are connected via the material 6. Specifically, both end portions 6 a in the left-right length direction (arrow B direction) of the rigid connecting member 6 are rigidly joined to the top portion 2 d of the fixed side rack 2 and the top portion 3 d of the movable side rack 3, respectively.

  The rigid connecting member 6 is provided horizontally along the horizontal movement direction (arrow B direction) of the movable rack 3 only between the top 3d of the movable rack 3 and the top 2d of the fixed rack 2. In the illustrated example, as shown in FIG. 1B, the rigid connecting member 6 has a planar rectangular structure, and is disposed over the entire length in the longitudinal direction of the racks 2 and 3 (arrow A direction). Is done. Accordingly, the force acting on each rack 2, 3 is transmitted from one rack 2, 3 to the other rack 3, 2 via the rigid connecting member 6.

  The non-accepting side surfaces 2b and 3b of the racks 2 and 3 have, as seismic elements, the upper and lower ends of the racks 2 and 3, respectively, from the upper and lower ends of the racks 2 and 3, respectively. A brace 7 is arranged in an oblique direction. FIG. 1C shows the fixed side rack 2. The braces 7 may be distributed over the non-receiving side surfaces 2b and 3b.

  Next, the operation of the structure damping structure 1 according to the first embodiment will be described. As shown in the right side of FIG. 2, the vibration damping structure 1 of the structure shown in FIG. 1 is rigidly connected to the top portions 2d and 3d of the two mass point systems 2 and 3 having the same height as they are. This corresponds to a vibration model connected by the material 6.

  The vibration model shown on the right side can be considered to be equivalent to the vibration model of the single mass system M1 having a double height, as shown on the left side. That is, only the top portions 2d and 3d of the pair of racks 2 and 3 are connected to each other by the rigid connecting member 6, and one rack 3 is supported on the support base 4 so as to be movable in the horizontal direction by the horizontal movable means 5, and the other By fixing the rack 2 to the support base 4, the pair of racks 2 and 3 are converted into a rack M1 having a double height.

  When earthquake motion is input from the support base 4, if the period of the ground motion is short and the period of the structure is longer than the period of the ground motion, as is well known, the vibration suppression effect is exhibited by the structure itself. The vibration suppression action works.

  When the fixed rack 2 fixedly constructed on the support base 4 is not connected to the adjacent rack 3 alone as shown in FIG. 2, it is half as high as the vibration model of the single mass system M1 on the left side in FIG. Thus, the response to the short-period ground motion is increased, and the vibration acceleration, interlayer shear force, and displacement (amplitude) of the fixed rack 2 are increased. On the other hand, as in the present embodiment, only the tops 2d and 3d of a pair of racks 2 and 3 (fixed side rack and movable side rack) having the same height are connected by the rigid connecting material 6, and the fixed side rack is connected. 2 is fixed to the support base 4, and the movable rack 3 is supported on the support base 4 so as to be movable in the horizontal direction by the horizontal moving means 5. The period can be made longer than the period of ground motion, and the vibration acceleration, interlayer shear force, and displacement (amplitude) of the structure can be reduced reasonably and efficiently.

  Further, a horizontal moving means 5 is provided between the movable side rack 3 and the support base 4, and the movable side rack 3 and the top portions 2 d and 3 d of the fixed side rack 2 are connected by the rigid connecting material 6. The racks 2 and 3 can be easily damped. In the racks 2 and 3 of the automatic warehouse illustrated in the first embodiment, the mass (weight distribution) of the vibration system changes depending on the loading state of the article. The vibration control effect can be obtained.

  FIG. 3 shows a second embodiment of the structure damping structure 1 according to the present invention. FIG. 3 is a front view of the structure damping structure 1 according to the second embodiment. In the second embodiment, damping means 8 and elastic means 9 are provided between the lower end 3 c of the movable rack 3 and the floor 4 that supports the movable rack 3.

  Only either the damping means 8 or the elastic means 9 may be provided between the movable rack 3 and the floor 4. As the damping means 8, any known hydraulic damper, viscoelastic damper, friction damper, or the like known in the vibration system may be adopted. As the elastic means 9, any linear spring, disc spring, leaf spring, or the like may be used.

  By providing the attenuating means 8, it is possible to dampen the vibration acting on the movable side rack 3, and thereby dampen the vibration of the fixed side rack 2 connected to the movable side rack 3 via the rigid connecting member 6. Thus, the structure can be efficiently damped by the damping means 8.

  By providing the elastic means 9, a restoring force can be applied to the vibration displacement generated in the movable rack 3, whereby the fixed rack connected to the movable rack 3 via the rigid connecting member 6. The restoring force can be applied to the vibration displacement generated in 2, and the structure can be efficiently damped by the elastic means 9. Further, by providing both the elastic means 9 and the damping means 8, further excellent vibration damping performance can be obtained.

  FIG. 4 shows a vibration model equivalent to that of the first embodiment shown in FIG. 2, taking as an example the case where only the damping means 8 is employed. The second embodiment is shown by a vibration model of two mass point systems 2 and 3 having the same height on the right side in FIG. 4. The lower end 3 c of the movable rack 3 and the support base 4 are connected to each other to provide a damping means 8. Provided.

  In the vibration model shown on the right side, a pole P having the same rigidity as that of the support base 4 is erected on the side of the vibration model of the single mass system M1 having the double height shown on the left side as in FIG. It can be considered equivalent to providing the damping means 8 between the upper end of the pole P and the upper end of the vibration model of the single mass system M1.

  The structure damping structure 1 according to the second embodiment shown in FIG. 3 is the same as the support base 4 in obtaining the same damping performance as the vibration model of the single mass system M1 shown on the left side of FIG. The rigid pole P is not required, and it is sufficient to simply provide the damping means 8 on the support base 4 between the movable rack 3 and provide the damping means 8 obtained by using the damping means 8. The performance can be ensured by a simple installation work of the damping means 8, and the racks 2 and 3 can be controlled reasonably and effectively.

  Further, the lower end 3c of the movable side rack 3 vibrates with the maximum amplitude in the entire structure composed of the fixed side rack 2 and the movable side rack 3 connected by the rigid connecting member 6, and therefore supports the lower end 3c. By providing the damping means 8 between the substrate 4 and the base plate 4, vibration can be attenuated extremely efficiently. In the illustrated example, only the attenuating means 8 is shown, but it is the same whether the elastic means 9 is provided instead of the attenuating means 8 or when both the attenuating means 8 and the elastic means 9 are provided. is there.

  FIG. 5 shows a modification of the first and second embodiments. FIG. 5 is a plan view of the structure damping structure 1 showing a modification. In this modified example, the stationary rack 2 and the movable rack 3 are provided with seismic elements in a plane perpendicular to the horizontal movement direction (arrow B direction) of the movable rack 3 (arrow A direction). . In addition to the brace 7 described in the first embodiment, the earthquake resistant wall 10 is used as the earthquake resistant element.

  The orthogonal direction is a longitudinal direction of the racks 2 and 3, and the orthogonal surface is a surface surrounded by the length direction and the height direction of the racks 2 and 3. Further, the seismic wall 10 and the brace 7 are not installed on the receiving surface sides 2a and 3a, but are installed on the non-receiving surface sides 2b and 3b so that articles can be taken out by the stacker crane.

  As a result, in this modification, the direction of the arrow B can be controlled by the rigid connecting member 6 and the horizontal moving means 5, and the direction of the arrow A can be controlled by the earthquake resistant elements such as the earthquake resistant wall 10 and the brace 7. Can shake. Of course, the earthquake-resistant wall 10 and the brace 7 are not necessarily provided in both the fixed rack 2 and the movable rack 3, and may be provided in any one of the racks 2 and 3. This modification may be adopted in combination with the embodiment shown in FIGS.

  FIG. 6 shows another modification. FIG. 6 is a front view of a structure damping structure 1 showing another modification. In this modification, the rigid connecting member 6 is provided with a damping member 11 that attenuates the force transmitted thereto. This modification may be employed in combination with the embodiment shown in FIGS. 1 and 3 and the modification shown in FIG. The damping member 11 may be any type like the damping means 8.

  By providing the rigid connecting member 6 with the damping member 11, the force transmitted from the fixed side rack 2 to the movable side rack 3 and the return from the movable side rack 3 to the fixed side rack 2 when earthquake motion is input. The damping force can be attenuated, and the damping effect can be enhanced reasonably and effectively. Moreover, only the damping member 11 is provided in the rigid connecting material 6, and the structure damping structure 1 can be simply configured.

  FIG. 7 shows still another modification. FIG. 7 is a front view of the structure damping structure 1 according to this modification. In this modification, the rigidity of the fixed rack 2 is set larger than the rigidity of the movable rack 3. This modification may also be adopted in combination with the embodiment shown in FIGS. 1 and 3 and the modification shown in FIGS.

  In order to make the rigidity of the fixed side rack 2 larger than that of the movable side rack 3, for example, the cross section of the constituent member of the fixed side rack 2 is made larger than the cross section of the constituent member of the movable side rack 3, or the configuration of the fixed side rack 2 What is necessary is just to enlarge the rigidity of the joining location between the structural members of the movable side rack 3 for the rigidity of the joining location between members.

  By increasing the rigidity of the fixed side rack 2 to which the seismic force is directly input from the floor 4 relative to the movable side rack 3 to which the seismic force is not directly input from the floor 4 by the horizontal movable means 5, the fixed side rack The vibration amplitude transmitted from 2 to the movable rack 3 can be effectively reduced, and the damping effect can be enhanced reasonably and effectively. In addition, only the rigidity of the fixed rack 2 is increased, and the structure damping structure 1 can be simply configured.

  FIG. 8 shows still another modification. FIG. 8 is a front view of the structure damping structure 1 according to this modification. In this modification, the fixed side rack 2 is provided on the floor 4 with seismic isolation support. That is, the seismic isolation device 12 is installed between the lower end 2 c of the fixed rack 2 and the floor 4. This modification may also be adopted in combination with the embodiment shown in FIGS. 1 and 3 and the modifications shown in FIGS.

  By installing the seismic isolation device 12 such as laminated rubber in the fixed rack 2, the entire structure including the fixed rack 2 and the movable rack 3 connected by the rigid connecting material 6 can be lengthened. Even if it comprises in this way, the damping effect can be improved rationally and effectively regarding the whole structure. Moreover, only the seismic isolation device 12 is provided between the fixed side rack 2 and the floor 4, and the structure damping structure 1 can be easily configured.

  In the case where both the pair of racks are isolated from the floor 4 without constituting the movable side rack 3, it is considered that this modification is compared with the case where these both racks may interfere with each other with their vibration amplitude. Then, the fixed side rack 2 and the movable side rack 3 vibrate at a distance from each other by the rigid connecting member 6, so that mutual interference does not occur and the damping structure 1 of a safe structure is configured. be able to.

  9 and 10 show a third embodiment of the structure damping structure 1 according to the present invention. FIG. 9 is a plan view of the structure damping structure 1 according to the third embodiment, and FIG. 10 is an enlarged front view of a main part. The fixed side rack 2 and the movable side rack 3 and both end portions 6a of the rigid connecting member 6 are pin-joined 13 so as to be rotatable around the height direction axis so as to allow mutual rotation.

  The mutual rotation means horizontal rotation around the axis along the height direction of the racks 2 and 3. Specifically, for example, as shown in FIG. 10, the pin joint 13 has a pin body 14 provided at the tops 2 d and 3 d of the racks 2 and 3 so as to be rotatable around an axis X in the height direction. The end 14a of the rigid connecting member 6 is rotatably engaged with the body 14. As a result, the rigid connecting member 6 and the racks 2 and 3 are pin-coupled 13 so as to be rotatable around the pin body 14.

  As shown in FIG. 9, the pin joints 13 are provided at least at the four corners of the rigid connecting member 6 having a planar rectangular shape. A plurality of pin joints 13 may be provided at appropriate intervals in the longitudinal direction (A direction) of the racks 2 and 3.

  The fixed rack 2, the movable rack 3 and the end 6 a of the rigid connecting member 6 are pin-joined 13 so as to be rotatable around the axis X in the height direction, thereby allowing the racks 2, 3 to rotate together. The torsional moment K is applied to the racks 2 and 3 due to the fact that the seismic force is applied obliquely to the rack and the weight distribution of the articles mounted on the racks 2 and 3 is imbalanced when the seismic force is applied. Even if this occurs, it is possible to release this twisting action by the pin joint 13 and prevent an excessive stress from being generated at the rigid joint portion between the racks 2 and 3 and the rigid connecting member 6. Can be controlled.

  Even if the pin joint 13 having the above-described configuration is applied to the rigid joint between the rigid connecting member 6 and the racks 2 and 3, the rigid joint is secured in the left and right width direction (B direction) of the racks 2 and 3. Of course, force and vibration amplitude can be appropriately transmitted between the racks 2 and 3.

  Such 3rd Embodiment can also be employ | adopted in combination with embodiment shown in FIG.1 and FIG.3 and the modification shown in FIGS. In the illustrated example, the case where the structure of the pin joint 13 is provided in both the fixed side rack 2 and the movable side rack 3 has been described, but it is needless to say that it may be provided only in one of the racks 2 and 3. is there.

  11 and 12 show a fourth embodiment of the structure damping structure 1 according to the present invention. FIG. 11 is a plan view of the structure damping structure 1 according to the fourth embodiment, and FIG. 12 is an enlarged front view of a main part.

  In order to allow mutual sliding movement between the fixed side rack 2 and the movable side rack 3 and the end 6a of the rigid connecting member 6, a direction orthogonal to the moving direction (B direction) of the movable side rack 3 ( A slide mechanism 15 is provided in the (A direction).

  Specifically, for example, as shown in FIG. 12, the slide mechanism 15 is provided with slide rails 16 at the tops 2 d and 3 d of the racks 2 and 3 along the longitudinal length direction (A direction) of the racks 2 and 3. . A pair of upper and lower bearing brackets 17 and 18 are provided at the end 6 a of the rigid connecting member 6 along the longitudinal direction of the racks 2 and 3. The upper and lower bearing brackets 17 and 18 rotatably support upper and lower ends of a support shaft 20 of a rotating roller 19 that rotates along the slide rail 16.

  The rack-side tip 17a of the upper bearing bracket 17 is slidably inserted into a receiving groove 21 formed in the racks 2 and 3 along the longitudinal direction thereof, and is rigidly connected to the racks 2 and 3. A rigid joint with the material 6 is ensured. A plurality of rotating rollers 19 are provided at appropriate intervals in the longitudinal direction of the racks 2 and 3 and the rigid connecting member 6.

  Between the fixed side rack 2 and the movable side rack 3 and the end 6a of the rigid connecting member 6, a slide mechanism 15 is provided in a direction (A direction) orthogonal to the moving direction (B direction) of the movable side rack 3, By allowing mutual sliding movement, similar to the pin joint 13, it is caused by the seismic force acting on the racks 2 and 3 in an oblique direction and the imbalance in the weight distribution of the rack-mounted articles when the seismic force acts. Even if a torsional moment is generated in the racks 2 and 3, this twisting action is released by the slide mechanism 15, and an excessive stress is generated at the rigid joint portion between the racks 2 and 3 and the rigid connecting member 6. Thus, vibration can be appropriately controlled.

  Even if the slide mechanism 15 having the above-described configuration is applied to the rigid joint portion between the rigid connecting member 6 and the racks 2 and 3, as in the pin joint 13, the horizontal width direction (B direction) of the racks 2 and 3 is as follows. Of course, it is possible to secure a rigid joint and to transmit force and vibration amplitude between the racks 2 and 3 appropriately.

  Such 4th Embodiment can also be employ | adopted in combination with embodiment shown in FIG.1 and FIG.3 and the modification shown in FIGS. In the illustrated example, the case where the slide mechanism 15 is provided in both the fixed side rack 2 and the movable side rack 3 has been described, but it is needless to say that the slide mechanism 15 may be provided only in one of the racks 2 and 3.

  In the above embodiment, the racks 2 and 3 of the automatic warehouse have been described as examples. However, the present invention can be similarly applied even to a building such as a high-rise building, thereby obtaining the same operation effect. Of course. In this case, unlike the racks 2 and 3 illustrated in the above embodiment, the configuration / concept of the receiving surface side 2a, 3a and the non-receiving surface side 2b, 3b is not necessary, and the brace 7 and the seismic wall 10 and the like are not required. The installation position of the seismic element may be set on the surface where the buildings face each other, the opposite surface, or both surfaces. Moreover, in the said embodiment, the racks 2 and 3 with large aspect ratio were illustrated and the left-right width direction was made into the moving direction (B direction), and the direction (A direction) orthogonal to this was demonstrated as the front-back length direction. However, in the case of a building, either the length direction or the width direction may be set as the movement direction (B direction), or may be the direction (A direction) orthogonal to the movement direction. The rigid connecting material 6 may be a flat rectangular shape such as a roof material or a slab material that can be moved by a resident, or may be a wire material such as a beam.

  The structure damping structure 1 described above can be applied not only to a structure such as a new building but also to an existing structure. In this case, one of the existing structures out of the pair of existing structures constructed by being fixed on the support base 4 is separated from the support base 4 and supported by the horizontal movable means 5. On the base 4, the movable side structure 3 is supported in such a manner as to be movable in the horizontal direction in the direction of contact with and away from the other existing structure, and the other existing structure is used as the fixed side structure 2. Good. In this way, except for the construction of the rigid connecting member 6, the separation from the support base 4 and the installation work of the horizontal movable means 5 can be performed only on one existing structure (movable side structure 3). The vibration damping structure 1 can be configured as a simple and effective structure that can reduce the vibration amplitude during an earthquake by inexpensive construction.
