Description

  The present invention relates to an article storage shelf configured by arranging a plurality of column frames in which a pair of front and rear columns are connected by a lattice in the width direction of the shelf.

Such article storage shelves are used to store articles by placing and supporting articles on a brace or the like that is connected and supported by a support frame.
In such an article storage shelf, when the column frame vibrates in the longitudinal direction of the shelf due to an earthquake or the like, stress may concentrate on the lower part of the column and the column may be damaged. An elastic vibration damping device is installed between the structural elements of the article storage shelf, such as between the lattice and the column or between columns arranged in the vertical direction of the shelf, and the column frame vibrates in the longitudinal direction of the shelf due to an earthquake or the like. When this occurs, the viscoelastic body is elastically deformed, and the elastic deformation of the viscoelastic body attenuates the vibration and suppresses the stress concentrated on the lower part of the column, thereby preventing the column from being damaged. (For example, refer to Patent Document 1).

JP 2003-118819 A

  However, in the above-described article storage shelf, the vibration damping device is configured as a viscoelastic body that suppresses vibration by elastically deforming the viscoelastic body. A return urging force is generated when the elastic body returns to the natural state, and the direction in which the return urging force of the viscoelastic body acts and the direction in which the column frame swings are the same direction, and the burden on the column is reduced. There is a risk of increasing it, and it is impossible to sufficiently prevent the breakage of the column.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an article storage shelf that can sufficiently prevent damage to a support column due to stress concentration on the lower part of the support column. is there.

In order to achieve this object, an article storage shelf according to the present invention is configured by arranging a plurality of column frames in which a pair of front and rear columns are connected by a lattice in the horizontal direction of the shelf. The feature configuration is
A viscous-type vibration damping device configured by filling a viscous material between a first resistance plate and a second resistance plate that are arranged to face each other in a posture along the shelf front-rear width direction and the shelf vertical width direction is the support frame. The first resistance plate is provided on one of a pair of upper and lower support frame bodies provided with a column connection portion for connecting the pair of front and rear columns, and the second resistor is provided on the other side. It is provided in a state where the plate is fixedly supported ,
A plurality of the lattices are provided over the entire width in the vertical direction of the shelf,
The vibration damping device is located between a pair of front and rear columns in the column frame and at a position away from the location where the lattice is present .

That is, in the viscous body type vibration damping device, the first resistance plate is fixedly supported by one of the pair of upper and lower support frames at a position corresponding to between the pair of front and rear columns in the column frame, and the pair of upper and lower support frames. The second resistance plate is fixedly supported on the other side of the first resistance plate, and the first resistance plate and the second resistance plate are arranged to face each other in a posture along the shelf horizontal width direction and the shelf vertical width direction. Since a viscous material is filled between the two resistance plates, when the column frame swings in the width direction of the shelf due to an earthquake or the like, the first resistance plate and the second resistance plate in the width direction of the shelf The viscous shear resistance force of the viscous body acts on the relative movement, and the vibration is attenuated by the viscous shear resistance force of the viscous body, thereby suppressing the concentration of stress in the lower portion of the support column.
Since the viscous body type vibration damping device is controlled by the viscous shear resistance force of the viscous body, the first resistance plate and the second resistance plate are moved together with the swing of the column frame in the longitudinal direction of the shelf. Since they do not generate return biasing force that returns them to their original state when they move relative to each other, it is possible to suppress an increase in the burden on the support columns when the vibration of the support frame is attenuated. The lower portion can be sufficiently prevented from being damaged. Incidentally, increase or decrease in the viscous shear resistance may be easily performed by could varying the gap between the amount and the first resistor plate and the second resistive plate of the viscous body.
Accordingly, it has become possible to provide an article storage shelf that can sufficiently prevent damage to the column due to stress concentration at the bottom of the column.

In addition , by providing a vibration damping device at a position corresponding to between the pair of front and rear columns in the column frame and at a position deviating from the location where the lattice exists, the vibration damping device does not overlap with the lattice in the lateral direction of the shelf. For example, even if the size of the vibration damping device in the width direction of the shelf is increased so as to provide a sufficient vibration damping action, it does not protrude in the width direction of the shelf from between the pair of front and rear columns. Or the amount which protrudes in a shelf width direction can be made small, and it came to be able to provide the article | item storage shelf which can achieve size reduction.

A second characteristic configuration of the article storage shelf according to the present invention is the first characteristic configuration, wherein the pair of upper and lower support frame bodies are a pair of left and right frames positioned at both lateral sides of the lattice in the lateral width direction of the shelf. The body portion is configured to fix and support the first resistance plate and the second resistance plate.

  In other words, each of the pair of upper and lower support frame bodies is constituted by a pair of left and right frame body parts, and the pair of left and right frame body parts are distributed and positioned on both lateral sides of the lattice. While the support frame does not protrude between the pair of front and rear columns in the shelf width direction or the amount of protrusion in the shelf width direction can be reduced, the first resistance plate or The two-resistor plate can be firmly fixed and supported, so that it is possible to provide an article storage shelf capable of firmly fixing and supporting the vibration damping device while achieving compactness.

The third characteristic configuration of the article storage rack to the present invention, the strut connecting the first or second feature Oite the configuration, each of the pair of upper and lower support frame is, to connect the pair of columns before and after in the strut frame The resistor plate connecting portion for connecting the first resistor plate and the second resistor plate to the portion and the column frame connecting portion is formed in a trapezoidal shape, and both ends of the long side portion are a pair of front and rear Each of the columns is connected to each of the columns, and the short side portion is connected to the first resistor plate and the second resistor plate.

  That is, since each of the pair of upper and lower support frame bodies is formed in a trapezoidal shape in which the column connection portion and the resistance plate connection portion are integrally formed, the connection between the pair of front and rear columns in the column frame and the column connection portion Since the first resistance plate and the second resistance plate can be connected by a single support frame formed in a trapezoidal shape, the number of members constituting the pair of upper and lower support frames can be reduced. Thus, the structure of the pair of upper and lower support frame bodies can be simplified, and thus the article storage shelf capable of simplifying the structure of the pair of upper and lower support frame bodies can be provided. It was.

According to a fourth feature configuration of the article storage shelf of the present invention, in any one of the first to third feature configurations, the vibration damping device or the upper and lower sides of the shelf are provided at a position corresponding to a lower portion of the support frame. A plurality of the vibration damping devices arranged in the width direction are provided.

  That is, if the vibration damping device is provided at a position corresponding to the lower portion of the support frame, the vibration of the support frame can be attenuated compared to the case where the vibration attenuation device is provided at a position corresponding to the upper portion of the support frame. Therefore, a single vibration damping device or a plurality of vibration damping devices arranged in the vertical direction of the shelf is provided at a location corresponding to the lower portion of the support frame, and a vibration damping device is provided at a location corresponding to the upper portion of the support frame. To provide an article storage shelf capable of efficiently attenuating the vibration of the support frame with few vibration damping devices, and efficiently attenuating the vibration of the support frame with few vibration damping devices. I was able to do it.

According to a fifth characteristic configuration of the article storage shelf according to the present invention, in any one of the first to fourth characteristic configurations, the vibration damping device is provided in each of the plurality of support frames arranged in the width direction of the shelf. There is in point.

  That is, since the vibration damping device is provided in each of the plurality of column frames arranged in the width direction of the shelf, the vibration of each of the column frames arranged in the width direction of the shelf is attenuated by the vibration damping device provided in the column frame. Therefore, the vibration of each of the plurality of support frames arranged in the width direction of the shelf can be appropriately damped, and accordingly, the vibration of each of the support frames arranged in the width direction of the shelf can be appropriately damped.
