Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to the structure of a brace attachment part of a rack used in automated warehouses and the like.

(Prior art and its problems) As shown in Figures 1 and 2, racks used in automated warehouses, etc. have cargo receiving trusses 1 erected at appropriate intervals in the horizontal length direction of the rack. A three-dimensional cargo storage space 4 is formed by a pair of left and right cargo receiving stands 3a, 3b whose front and rear ends are supported by a pair of front and rear truss columns 2a, 2b forming the cargo receiving truss 1. However, the receiving trusses 1 are not only connected to each other by horizontal connecting members at their upper ends and at appropriate intermediate positions, but also to each other by vertical braces 5 and beams 6 at the rear of the rack. Concatenated.

When connecting the vertical brace 5 or the beam 6 to the rear column 2b of the load receiving truss 1, conventionally, as shown in FIG. A mounting seat 9 having a mounting bolt hole 8 at the tip of the support member 7
are welded together, and when assembled easily on site,
Bolt holes 1 for attaching braces and beams
0 and a bolt hole 11 for mounting to the mounting seat 9, the brace mounting plate 12 is connected to both the bolt holes 8,
It was fixed to the mounting seat 9 using bolts and nuts.

In such a conventional brace attachment structure, it is not only necessary to weld the support member 7 to the support column 2b and the attachment seat 9 to the support member 7, but also to weld the support member 7, the attachment seat 9, and the brace. Mounting plate 12-3
This required parts, which was the key to reducing the overall cost of the rack. Of course, it was also considered to weld the brace mounting plate 12 directly to the tip of the support member 7, but it would only eliminate the mounting seat 9 and no great effect could be expected.

(Means for Solving the Problems) The present invention proposes an easy brace mounting structure that can solve the conventional problems as described above. The piece is cut and raised, the tongue piece is welded to the rack post, and the brace is attached to the brace mounting plate.

(Embodiment) An embodiment of the present invention will be described below with reference to the attached FIGS. It is a plate with a vertically elongated opening 1 in the center having a width slightly smaller than the width of the support column 2b.
5 is formed by cutting and raising tongue pieces 16a and 16b that stand up at right angles from the upper and lower side edges to the back side. The pair of upper and lower tongue pieces 16a, 16b
is press-worked into an arc shape whose arc center is located at the center of the longitudinal opening 15, and the inner ends of both arc-shaped tongues 16a, 16b are welded 17 to a predetermined position of the support column 2b. It is attached firmly. The brace 5 and beam 6 are attached to the brace mounting plate 13 by bolting, as in the conventional art.

(Operations and Effects of the Invention) According to the brace attachment structure of the present invention that can be implemented as described above, the tongue piece corresponding to the conventional support member 7 is integrally formed by cutting and raising the brace attachment plate. Therefore, only welding is required to secure the tongue piece to the support, and the number of welding points is halved. Moreover, it is sufficient to use only one brace mounting plate with integrally molded tongue pieces, and the number of parts can be significantly reduced, so a significant cost reduction can be expected as a whole.

In particular, when forming a pair of upper and lower arcuate tongues by cutting and bending as in the embodiment, sufficient support is required as in the case where a separate support member 7 is used between the column and the brace mounting plate. Even though the space can be secured, the mounting strength of the brace mounting plate can be sufficiently increased, and a decrease in strength can be minimized.
