[Construction of Rack Device] A method of constructing a rack device using the above-mentioned components of the rack device will be described below. The constituent members are erected on the floor at predetermined intervals in the left-right direction so that the front columns 2 are located on the front side and the rear columns 2 are located on the rear side, and horizontal bars or lattice bars are bolted to required parts. -The rack device was constructed by carrying out work such as handing over using nuts. In the rack apparatus constructed in this manner, the articles are placed so as to straddle the article support rails 5 on the left and right opposite to each other without interposing the columns 2.

[0004]

Disadvantages of the Prior Art The components of the conventional rack device have the following disadvantages. First, in order to eliminate the welding work at the construction site, after a large number of article support shelves 3 are welded and fixed to the pillars 2 at the factory to complete the components, they are carried into the construction site and a rack device is constructed. However, there is a drawback in that the constituent members are bulky and the transport efficiency is extremely poor. Secondly, since welding work is required, a welder having a welding skill, which is a special skill, is required, and there is a drawback that the working environment is deteriorated by gas or the like generated by the welding work.

[0005]

[Means for Solving the Disadvantages] The present invention adopts the following means in order to eliminate the above disadvantages. This invention includes a pair of front and rear columns, and arms that are attached to the left and right walls of the columns at predetermined intervals in the height direction, and that form a pair of arms.
It has an article support bar that can be handed over to these front and rear arms, and has an upward engagement piece that engages with an engagement hole formed in the left and right walls of the column at the base of the arm and the left and right walls of the column. A fitting protrusion that fits into a fitting hole formed below the engagement hole is provided.

[0006]

The present invention has the following functions. After a pair of columns are erected at a predetermined interval in the front-rear direction, the upward engaging pieces of the arms are engaged with the engaging holes of the left and right walls of the columns, and the pair of front and rear walls of the columns are fitted together. The fitting protrusions of the arms are fitted in the holes, and then the article support bars are passed to the arms forming a front and rear pair.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on the embodiments shown in the drawings. In this specification, the front means the left side in FIG. 4, the rear means the right side in FIG. 4, and the left means the back side in FIG.
The right side means the same side.

Each of the columns 11 has an outward facing wall 12, right and left edges of the outward facing wall 12, and right and left walls 13 connected to each other at a right angle thereto, and edges of the left and right walls 13.
It has an inclined projecting wall 14 that is continuously provided so as to be opposed to each other, and an opposing wall 15 that is provided so as to be parallel to each other at the edges of these projecting walls 14. Slits 16 are formed between the opposing walls 15. The front and rear columns 11 are configured such that the opposing walls 15 face each other.

Engagement holes 18 are formed in each of the left and right walls 13 of the support column 11 in the height direction of the support column 11 at a mounting interval of an arm 21 (article support bar 27) described later. A pair of front and rear fitting holes 19 are formed in the left and right walls 13 so as to be located below the engagement holes 18.

An upward engaging piece 22 which engages with the engaging hole 18 and a pair of front and rear fittings which are fitted into the fitting hole 19 are provided at the base of the arm 21 which is attached to the column 11 and has an inverted U-shaped cross section. The projection 23 is formed. The upward engaging piece 22
After being fitted into the engaging hole 18, it comes into contact with the upper edge portion of the engaging hole 18 from the inner surface, and the fitting projection 23 is aligned and fitted into the fitting hole 19.

An article support shaft 27 having an inverted U-shaped cross section, a bolt 28, and a nut 29 are mounted on the arm 21 which is paired up and down.
It is designed to be handed over. That is,
After the bolt 28 is fitted through the through holes formed in the arm 21 and the article support sleeve 27, the nut 29 is screwed into the bolt 28, so that the article support sleeve 27 is fixed to the arm 21. In addition, in order to prevent the head of the bolt 28 from protruding from the upper surface of the article support shaft 27, the article support shaft 27 is formed with a recess into which the head of the bolt 28 sinks.

[0012]

[Method of Using the Embodiment] An example of constructing a rack device using the components of the embodiment will be described below. First, the columns 11 on the front side are erected at predetermined intervals so as to be lined up in the left-right direction,
The rear columns 11 are erected on the rear side of these front columns 11 so as to be lined up with a predetermined gap therebetween. The pillars 11 are erected so that the opposing walls 15 of the front and rear pillars 11 face each other. At the same time, work such as passing the lattice bar 30 between the front and rear columns 11 is performed. After that, the upward engaging piece 22 of the arm 21 is attached to the engaging hole 1
8, the fitting protrusion 23 of the arm 21 is fitted into the fitting hole 19. After that, the arm 21 that becomes the front and rear set
Then, the article support shaft 27 is stopped by bolts 28 and nuts 29. Although the bolt 28 and the nut 29 are representative of the connecting tool, it goes without saying that other known connecting tools can be used.

[0013]

The present invention has the following effects due to the above-mentioned configuration. Since the rack component is an assembling type that does not require welding, it can be transported in a disassembled state, that is, in a non-bulky state, when it is transported from a factory to a construction site. The transportation efficiency is good, and the rack device can be constructed without welding work at the construction site. Unlike the conventional method, the arm can be attached to the column and the article support bar can be attached to the arm without performing welding work, so not only does a welder with a special skill of welding technology be required, but also welding is possible. There is no possibility that the working environment will be deteriorated by the gas generated at times.
