Description

[Detailed Description of the Invention] The present invention relates to a stiffening structure for columns arranged in the depth direction of a multi-post type shelf.

For multi-post shelves, in order to connect the shelf supports rigidly, the four corners of the top plate and bottom plate are rigidly connected to the pillars, or the lower part of the pillars is rigidly connected to the framed underframe, and each support is erected. or install wide plates in the depth direction of the shelf, or install diagonal members between the supports.
Various other methods have also been adopted.

Among the above-mentioned stiffening structures, the method of attaching diagonal members between the columns has a relatively simple structure and has a large stiffening effect, but the method of installing diagonal members between the columns is relatively simple and has a large stiffening effect. In a multi-column double shelf constructed by vertically erecting shelves, there are problems that must be solved in order to increase the rigidity in the depth direction of the shelf by attaching the diagonal members.

As shown in FIGS. 1 and 5, when the front and rear columns a and c are arranged with their open sections facing each other and the intermediate column b is arranged between them, the front and rear columns a and c and the intermediate column are usually arranged. Since the shelf board locking hole spacing of b is A-2Z, the center of intermediate pillar b is set upright at a distance of 1/2 of shelf depth D, and A = 1/2D. Front and rear columns a, c and intermediate column b to which diagonal members are to be attached
The internal dimensions between them are x and y, respectively, and always x
The relationship is <y.

Therefore, if the same diagonal members were installed between x and y, the installation angles of the diagonal members would be different, and the upper and lower joining positions would also be different, so there was a risk of losing the balance in terms of rigidity. In addition, in order to attach the diagonal members, there are two types of processing for the front and rear columns a and c and the intermediate column b.
As the number of processing steps increased, it became an obstacle to mass production.

On the other hand, if the mounting angles of the diagonal members and the upper and lower joint positions are made the same, the diagonal members will have different length dimensions, increasing the number of types of diagonals to be manufactured, and also becoming a factor in high costs.

This proposal relates to an improvement of the shelf depth stiffening structure that eliminates these drawbacks, and involves three pillars with a U-shaped open cross section that are erected in a line in the shelf depth direction with a predetermined interval in the shelf width direction. In a double-column double shelf arranged in multiple sets, among the three columns in the depth direction,
The intermediate columns are erected and oriented so that the opening surfaces of the front and rear columns face each other, and the opening surfaces of the intermediate columns are alternately oriented opposite to the opening surfaces of either one of the front and rear columns, It is characterized in that diagonal members are attached between the columns where the opening surfaces of the front and rear columns and the middle column face each other, and the diagonal members are arranged alternately in the direction of the shelf frontage. The object of the present invention is to provide a stiffening structure that is highly suitable for mass production and that effectively stiffens the shelf in the depth direction and balances the rigidity of the entire shelf.

As described above, in the present invention, among the three columns in the depth direction, the opening surfaces of the front and rear columns face each other, and the opening surfaces of the intermediate column are arranged in opposite directions. Intermediate struts are erected facing one opening surface, diagonal members are attached between the struts where the opening surfaces of the front and rear struts and the intermediate struts face each other, and the diagonal members are arranged alternately in the direction of the shelf frontage. Therefore, while making the spacing between the front struts and intermediate struts uniform and the distance between the rear struts and intermediate struts, the distance between the web parts between the front struts and intermediate struts to which diagonal members are to be attached, and the web parts between the rear struts and intermediate struts are adjusted. The interval can be widened and made equal,
As a result, the rigidity and strength in the shelf depth direction can be significantly improved, and the length and installation angle of the diagonals can be made constant, making it sufficient to manufacture only one type of diagonal, which simplifies processing and allows for mass production. This makes it possible to achieve significant cost reductions.

In addition, in this invention, the direction of the opening surfaces of the intermediate struts is alternately changed across the opening direction, and the inclination direction of the diagonal members interposed between the opening surfaces is also alternately changed across the opening direction, so that the entire double-column double shelf is The strength and rigidity of the shelf can be made uniform, and as a result, even if an item is placed only on one of the front and rear shelf openings, the shelf will remain firmly upright regardless of the position where the item is placed. can be supported.

Furthermore, in the present invention, both the upper and lower ends of the diagonal material interposed between the opening surface of the intermediate strut and the opening surface of one of the front and rear struts opposite thereto are integrally screwed to the web portions of these struts. The upper and lower ends of the diagonal members can be firmly connected to the struts, the tensile or compressive force acting on the diagonal members can be reliably transmitted to the struts, and a strong truss structure can be constructed in the longitudinal direction of the shelf.

An embodiment of the present invention illustrated in FIGS. 2 to 6 will be described below.

Reference numeral 1 denotes a double-column double shelf, and the double-column double shelf 1 has several sets of front columns 3 on a horizontal frame 2, as shown in FIG.
a, a middle column 3b and a rear column 3c are erected, a top plate 4 is attached to the top of the column 3, and several shelf boards 5 are vertically suspended between adjacent columns 3 to form a frame. has been done. The double-column double shelf 1 is completed by further attaching side plates, partition plates, etc. (not shown) to the frame shown in FIG. 2.

The front pillar 3a, the middle pillar 3b, and the rear pillar 3c are each made of a member having a U-shaped open cross section, and the opening surfaces of the front and rear pillars 3a, 3c face each other, and the front and rear pillars 3a and 3c is both flange surface 3
Similarly, the middle pillar 3b has two vertical rows of shelf plate locking holes 3f on both flange surfaces 3d.

As for the relative relationship between the depth dimensions of the hole cores, since the depths of the shelves installed on the front and rear surfaces of the shelf are equal, the core dimensions of the shelf board locking holes 3f are A-2Z, and the opening surface of the intermediate column 3b is A set of pillars 3 is constructed by standing in a row in the shelf depth direction facing the opening surface of either the front pillar 3a or the rear pillar 3c.
Note that the center of the intermediate column 3b is located at a distance of 1/2 of the distance between the front and rear columns 3a and 3c.

The intermediate columns 3b are erected so as to face the opening surfaces of either of the front and rear columns 3a, 3c so that the opening surfaces of the intermediate columns 3b adjacent to each other in the shelf frontage direction are opposite to each other.

Therefore, as shown in FIG. 3, the intermediate columns 3b are arranged so as to alternately face the front columns 3a and the rear columns 3c in the shelf frontage direction.

Furthermore, in order to reinforce the rigidity of the pillar 3, in the shelf depth direction, the opening surface of the intermediate pillar 3b and the front and rear pillars 3a,
A diagonal member 6 is attached between the pillars whose opening surfaces 3c face each other.

As shown in FIG. 4, the diagonal member 6 is made by cutting a steel material with a rectangular cross section into a predetermined length, and crushing both ends 6a flat with a press. It is symmetrically bent at a predetermined angle and further provided with bolt holes 6b.

As shown in FIGS. 2 to 6, the diagonal member 6 has an end 6a on the intermediate column 3b side mounted above the shelf, and an end 6a on the front and rear columns 3a, 3c side attached below the shelf. The diagonal member 6 is attached diagonally to the shelf 1. That is, the column 3 consists of left and right flange portions 3d and a web portion 3e connecting the left and right flange portions 3d, and a bolt hole 3g is formed in the web portion 3e, and the intermediate column 3b
The bolt holes 3g are the bolt holes 3 of the front and rear columns 3a and 3c.
It is formed above g. Then, the end portion 6a of the diagonal member 6 is superimposed on the web portion 3e, and the bolt 7 is inserted into the bolt hole 3g and 6b formed in the web portion 3e of the column 3 and the end portion 6a of the diagonal member 6, respectively, and the nut is inserted. 8, the diagonal member 6 is secured to the front and rear columns 3a, 3c and the intermediate column 3b.
It is strung diagonally in between.

The diagonal members 6 are disposed between columns in which the opening surfaces of the front columns 3a or rear columns 3c and the opening surfaces of the intermediate columns 3b are alternately opposed in the shelf frontage direction, and thus the third
As shown in the figure, the diagonal members 6 are arranged alternately in the direction of the shelf frontage.

Since the embodiment shown in FIGS. 2 to 6 is constructed as described above, the front and rear columns 3a, 3
Each pillar 3 can be rigidly held by the diagonal member 6 spanned between the middle pillar 3b and the middle pillar 3b.

Furthermore, in this embodiment, since the diagonal members 6 are arranged alternately in the direction of the shelf frontage, the rigidity of the double-column compound shelf 1 is kept balanced, and each member of the double-column compound shelf 1 receives external force uniformly. I can do it.

Furthermore, in this embodiment, since the diagonal members 6 are installed only between the columns where the opening surface of the intermediate column 3b and the opening surfaces of the front and rear columns 3a and 3c face each other, the length of the diagonal members 6 may be of one type. , it is possible to reduce costs by mass producing diagonal members 6.

Furthermore, in this embodiment, since the mounting angle and the upper and lower joining positions of the diagonal members 6 do not differ between each column 3, the front and rear columns 3a, 3c and the intermediate column 3
The machining of the mounting portion of the diagonal member 6 in b is the same for each pillar 3, so the machining is not complicated and the number of machining steps can be reduced.

Furthermore, in this embodiment, the diagonal member 6 is directly fixed to the column 3, which reduces assembly man-hours and requires fewer parts than when the diagonal member 6 is fixed via a member such as a fixing gusset. . Furthermore, since the fixing portion is hidden within the U-shaped pillar 3, the appearance is good.

In the embodiment shown in FIGS. 2 to 6, one diagonal member 6 is installed between the pillars 3 in the depth direction, but as shown in FIG.
One end of the two diagonal members 6 may be overlapped and attached on c, and the other ends of the two diagonal members 6 may be opened vertically. In this way, the same effects as those shown in FIGS. 2 to 6 can be achieved, and a further stiffening effect can be expected.
