Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to, for example, shelves installed in a factory and into which goods are loaded and unloaded using a forklift truck, and to the connection of shelves in an automated warehouse.

Conventional technology A shelf onto which goods are loaded and unloaded by a forklift truck or a loading/unloading device in an automated warehouse is fixed by connecting the front and rear columns 61 with diagonal members 62 and longitudinal beams 63, as shown in FIG. 7, for example. Furthermore, the left and right columns 61 are connected and assembled by a cross beam member 64. Additionally, armrests 65 are provided protruding from the opposing positions of the left and right columns 61, and arm rails 66 for supporting a load 67 are attached between the front and rear armrests 65.

Conventionally, the pillar 61 is mainly made of square cylindrical steel material,
The shelves were assembled in a factory by welding the columns 61, diagonal members 62, vertical beam members 63, and cross beam members 64 to each other, and then transported by truck or the like to the factory where it was installed.

Problems to be Solved by the Invention However, since the assembled shelves have a large volume, it is difficult to transport them to nearby areas.
There was no problem with transportation, but transportation costs were high when transporting to remote locations. In addition, the diagonal material that connects the columns is cut diagonally at the end so that it is attached to the side of the column. It required advanced welding techniques as it was welded against a surface.

SUMMARY OF THE INVENTION An object of the present invention is to provide a frame shelf connection structure that can be transported as a single item, can be easily and accurately connected and assembled on site, can reduce transportation costs, and can eliminate the need for welding. do.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention has an outer plate portion, an inner plate portion, and left and right side plate portions facing each other, and a slit is provided in the central longitudinal direction of the inner plate portion. A supporting column having a C-shaped cross section is provided, a reinforcing recess is formed along a position facing the slit in the outer plate part, and a reinforcing recess is formed along both edges of the slit in the inner plate part, and each protrudes outward at a right angle to the inner plate part. A pair of left and right connecting plate portions are provided, and a connecting member is provided at both ends of the connecting plate portions, which are inserted between the connecting plate portions and fixed via a fixture to connect the supporting columns facing each other.

Effect In the above configuration, by inserting the connecting member between the connecting plate parts and fixing it with a fixing tool, the posts can be easily connected and assembled on site without the need for welding work, and the fence can be assembled as a single part. can be transported, reducing transportation costs.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 to 4.

As shown in FIG. 2, this shelf 1 has pillars 2 erected at predetermined intervals in the front and rear and left and right directions.

Between the front and rear columns 2, there is a horizontal member 3 between the upper and lower ends.
are connected, a plurality of diagonal members 4 are connected, and the front and rear columns 2 are connected and fixed to each other.

Further, the left and right columns 2 are connected to horizontally continuous horizontal beams 5 at predetermined positions on the front and back surfaces of the shelf 1 via bolts. Arms 6 that project horizontally toward the left and right columns 2 are detachably attached to each column 2 at opposing positions of the left and right columns 2, respectively.

This arm 6 consists of a connecting member 7 and a arm 8 attached to the support 2, and a arm rail 9 for supporting the bottom of the load 11 is connected between the tips of the arm 8 of the front and rear struts 2. Furthermore, a reinforcing diagonal wire member 10 is connected in the diagonal direction between the intersection of the support column 2 and the horizontal beam 5. Furthermore, a seating member 12 is housed at the lower end of the column 2.

As shown in FIG. 4, the support column 2 has an outer plate part 21, an inner plate part 22, and left and right side plate parts 23, 23 facing each other, and a slit 2 extending longitudinally in the center of the inner plate 22.
4 is formed to have a C-shaped cross section.

A reinforcing recess 25 extending in the longitudinal direction is formed in the outer plate part 21 at a position facing the slit 24, and a pair of left and right connecting plate parts 2G are bent outward at 90 degrees from the edge of the slit 24 and protrude from the inner plate part 22. are formed facing each other along the slit 23.

The horizontal member 3 and diagonal member 4 that connect the front and rear columns 2 are, for example, mutually opposing side plates 3a, 4a and these side plates 3a.
, 4a are connected at side edges, and a channel-shaped one is used. As shown in Figure 1,
The column 2 is arranged in front and rear positions so that the connecting plate parts 26 face each other, and connecting holes 28 are formed in the end side plates 3a and 4a between the connecting plate parts 26 in which the connecting holes 27 are formed. Horizontal members 3 and diagonal members 4 are inserted and reconnection holes 27.2
A rivet 29 (an example of a connector) is inserted into the 8 and tightened. Further, as shown in FIG. 3, at both ends of the horizontal member 3 and the diagonal member 4, a reinforcing portion 30 is formed in which the connecting plates 3b and 4b are folded back between the side plates 3a and 4b to reach the vicinity of the connecting hole 28. This prevents deformation of the horizontal member 3 and diagonal member 4 due to tightening of the rivet 29. Further, here, the rivet 29 may be a single long rivet that is inserted between both the connecting plate parts 26, and as shown in FIG. 29' may also be used.

FIG. 5 shows another embodiment. The connection strength between the support 2 and the horizontal member 3 or diagonal member 4 is determined by
It is greatly influenced by the shear strength between the connecting hole 27 and the distance 2 to the tip edge. Therefore, in this embodiment, the pillar 4
A folded portion 43 is formed by bending the tip end edge of the first connecting plate portion 42 by 90 degrees to the side over the entire length of the connecting plate portion 42,
The shear strength of the connected parts has been improved.

FIG. 6 shows still another embodiment in which the interval d between the slits 52 of the support column 51 is narrowed, and in this case, the horizontal member 53
The ends of the diagonal members 54 are formed into an open flat shape using a press or the like, and are inserted between the connecting plate portions 55 and fixed with rivets 56. In this embodiment, cylindrical pipes can be used for the horizontal members 53 and diagonal members 54.

In addition, in each of the above embodiments, rivets 2929',
56 was used, but bolts and nuts may also be used.

Effects of the Invention As described above, according to the present invention, the strength of the column in which the slit is formed is ensured by the reinforcing recess, and furthermore, by inserting the connecting member between the connecting plate parts and fixing it with the connector, the column can be strengthened. Since the pieces are connected via connecting members and can be easily assembled on site, welding work can be eliminated, the shelves can be transported as child parts, and transportation costs can be reduced.
