DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an article storage shelf used in, for example, an automatic warehouse, and more particularly, to an article storage shelf.
It is composed of a plurality of upright columns and a plurality of article mounting beams connected at intervals vertically along the longitudinal direction of the columns, and a plurality of articles are vertically and horizontally. The present invention relates to an article storage shelf configured to be able to be placed and configured to be able to place two or more articles side by side on a beam between columns that are horizontally adjacent to each other when viewed from the frontage.

[0002]

2. Description of the Related Art In such an article storage shelf, a pallet on which articles are placed on a plurality of beams positioned above and below, or articles are directly placed, and various articles are vertically stacked. Therefore, a large compressive force is gradually applied to the column supporting the beam for placing articles, as it goes downward. However, in the past, for the reason of manufacturing the support column, the support column for supporting the beam was formed of a member such as a long mold steel having the same cross-sectional shape in the longitudinal direction. there were.

[0003]

In other words, for the members constituting the column, conventionally, the required strength is determined from the compressive force acting below the column, and the column is formed by using a mold steel or the like having the required strength. I was Therefore, for parts where excessively large compressive force does not act, such as above the columns, the use of unnecessarily strong members results.
This causes a problem that the cost of the article storage shelf is increased.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide a supporting column for supporting a beam for placing articles without using an unnecessarily strong member. The struts can be made of steel with the same cross-sectional shape, etc., while reducing costs as much as possible.
An object of the present invention is to provide an article storage shelf capable of providing a support with necessary strength.

[0005]

In order to achieve this object, according to the first aspect of the present invention, a reinforcing column shorter than the column is provided between columns adjacent in the left-right direction as viewed from the frontage. Since the intermediate portion of the lower beam of the plurality of beams positioned above and below is connected to the reinforcing column, a part of the compressive force acting on the lower portion of the column is connected to the column. Transmitted to the reinforcing column via the beam,
The reinforcing column bears part of the compressive force acting on the column. Therefore, the column does not need to be made of an unnecessarily strong member over its entire length, and can also be made of a mold steel or the like having the same cross-sectional shape. High strength.

According to the second aspect of the present invention, the beam connected to the reinforcing column is composed of a plurality of split beams, and each split beam is connected to the support column and the reinforcing column or to the two reinforcing columns. Therefore, the reinforcing column can be assembled without obstructing the transfer of the article. That is, it is also possible to connect the beam to the reinforcing column without splitting, but in that case, the reinforcing column projects from the front and rear surfaces of the beam in plan view,
There is a possibility that the protruding reinforcing column will be an obstacle when transferring goods to the beam, but by dividing the beam into beams, the reinforcing column does not project much from the front and rear surfaces of the beam in plan view This makes it possible to prevent the transfer of articles from being disturbed and to provide an excellent appearance.

According to the third aspect of the present invention, since a plurality of beams are connected at intervals vertically along the longitudinal direction of the reinforcing column, the compressive force acting on the lower portion of the column is reduced. Transmitted to the reinforcing column via a plurality of beams, the reinforcing column bears a greater compressive force, and the compressive force acting on the column can be further reduced. It is effective for

According to the fourth aspect of the present invention, a long reinforcing member is provided below the column along the column,
Since the reinforcing member and the column are connected and fixed to each other, the lower portion of the column on which a large compressive force acts can be partially reinforced, and the lower portion of the column itself can be cooperated with the above-described reinforcing column. Can be reduced more effectively, and it is particularly effective for shelves that store articles in multiple stages.

According to the fifth aspect of the present invention, a pair of long reinforcing members are provided, and near the both ends in the longitudinal direction of the pair of reinforcing members in a state where the pair of reinforcing members are substantially parallel to each other. Connected and fixed by a horizontal connecting member that is substantially orthogonal, and
Since the reinforcing frame is formed by connecting and fixing the pair of reinforcing members with the diagonal connecting members obliquely intersecting with the reinforcing members, the pair of reinforcing members are mutually reinforced by the interposition of the horizontal connecting members and the diagonal connecting members. As a result, the reinforcing frame itself becomes a very strong structure. By arranging both reinforcing members of the reinforcing frame along the lower portions of the pair of columns adjacent in the front-rear direction when viewed from the frontage, the lower part of the pair of columns adjacent to the front and rear can be strongly reinforced. In addition, for example, when assembling the reinforcing frame in advance and assembling the reinforcing frame at the time of assembling the article storage shelf, the reinforcing frame has a shape retaining structure that cannot be deformed. Also becomes easier.

According to the sixth aspect of the present invention, the reinforcing frame is formed in a rigid frame structure by rigid joining, so that the reinforcing frame can be effectively reinforced by improving the strength.

According to the seventh aspect of the present invention, since the article storage shelves comprising the columns and the beams are constructed in an assembling truss structure by pin joining, compared with a case in which they are constructed in a rigid frame structure by welding. When the assembling work of the article storage shelves at the site is easy, the work efficiency can be improved, and when the reinforcing frame has a ramen structure as described above, for example, the reinforcing frame is pre-assembled. Thus, while the entire article storage shelf has a truss structure that is easy to assemble, necessary parts can be reliably reinforced by a reinforcing frame having a ramen structure.

In the article storage shelf 1 having a relatively small number of steps, it is also possible to reinforce with only the reinforcing columns 10 without using the reinforcing frame 20. In this case, it is needless to say that the number of steps to be reinforced by the reinforcing columns 10 can be variously changed in consideration of the strength of the columns 6, the load of the stored articles A, and the like. Similarly, in the case of the combined use of the reinforcing columns 10 and the reinforcing frames 20, various changes can be made in consideration of the strength of the columns 6 and the like.

In the case of the combined use of the reinforcing columns 10 and the reinforcing frame 20, the higher the vertical height of the article storage shelf 1 and the greater the number of steps, the more effective it is. One example is shown in FIG. The article storage shelf 1. The article storage shelf 1 is capable of storing articles A in 15 levels up and down, reinforced from the bottom up to the sixth level with reinforcing columns 10, and reinforced from the bottom up to the third level with a reinforcing frame 20 together. . In the vertically high article storage shelves 1, since the compressive force acting on the support columns 6 is extremely different between the upper and lower sides, the reinforcing columns 10 and the reinforcing frame 2

Further, the example in which the beam 9 to be reinforced by the reinforcing column 10 is constituted by the split beam 9A is shown, but the beam 9 extending between the adjacent columns 6 is used without using the split beam 9A, and the beam 9 and the reinforcing column are used. 10 can be connected to each other. In order to reinforce the beam 9 having a plurality of stages,
The reinforcing columns 10 can be erected along the front and rear surfaces of the beams 9, and the reinforcing columns 10 can be connected to the beams 9.

The shape of the reinforcing member 16 and the method of connecting the reinforcing member 16 to the column 6 can be changed in various ways. For example, the reinforcing member 16 may be formed of various types of steel such as a channel, or the rivet 17 may be replaced by bolts and nuts. Can also be used to connect to the column 6, and as the connecting member for connecting the two reinforcing members 16, a round steel pipe or a bar can be used instead of the round pipes 18 and 19, and the connecting member can be used. The number and the like can be variously changed in consideration of the scale of the article storage shelf 1 and the weight of the articles A to be stored.

In the above embodiments, two articles A are arranged side by side on the beam 9 between the columns 6 adjacent to each other in the left-right direction. However, three or more articles A are arranged side by side. It can also be configured to be placed. For example, 3
