Abstract

PURPOSE:To firmly fasten a bolt to a nut without play and to facilitate on-site assembly by projecting the peripheral edges of bolt holes and by forming tapered parts at the surfaces facing a bolt part and a nut to each other. CONSTITUTION:In connecting an arm 17 to a bracket 16, firstly, both the bolt holes 1, 2 are agreed to each other to pass through a bolt 4 and to screw a nut 5. Fastening tire nut 5 a tapered part 4a formed on a bolt head part 4A abuts to the edge part 6 of the bolt hole 1 from its outside to provide deformation to the nut 5 side and a tapered part 5a formed on the nut 5 abuts to the end surface 3a of a projected edge part 3. The bolt 4 is integrated with the nut 5 without play to the bracket 6 and the arm 7.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to various framed shelves, such as framed shelves for automated warehouses and framed shelves that allow loads to be loaded and unloaded by forklifts.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 5 to 9, in a frame rack 10, columns 12 are erected from a base frame 11 at predetermined intervals in front, rear, left and right. The front and rear columns 12 are connected and fixed to each other via the horizontal members 13 and the diagonal members 14, and the left and right columns 12 are provided with horizontal beams 15 which are continuous in the lateral direction at predetermined positions on the back surface of the frame shelf 10. They are connected and fixed to each other via. Further, on the rear side of the frame shelf 10, the column 12 and the horizontal beam 15
A brace attachment plate or brace located at the intersection of is provided.

Left and right receiving brackets 16 are removably attached to the outer surfaces of the columns 12, and arms 17 are attached to the inner surfaces of the receiving brackets 16 and the free ends of the arms 17 facing each other in the front and rear direction. Arm rails 18 are connected in between. And between the left and right arm rails 18, the pallet
Configured to support load 20 (or directly load 20) via 19.

The column 12 has an outer plate portion 21 and an inner plate portion 22 and left and right side plate portions 23 that face each other, and a slit 24 is formed in the center of the inner plate portion 22 in the longitudinal direction.
The cross-section is formed into a substantially C-shaped material. And the inner plate 22
A pair of left and right connecting plate portions 25, which are bent outward from the edge of the slit 24 by 90 degrees and project, are formed along the slit 24 so as to face each other. The ends of the horizontal member 13 and the diagonal member 14 are inserted between the connecting plate portions 25, and are connected and fixed by bolts and nuts or rivets.

On the outer plate portion 21, the receiving bracket 16
A bolt hole 26 for connecting the two is formed, and on the other hand, a bolt hole 27 is also formed in the receiving bracket 16. Then, the receiving bracket 16 is connected to the support column 12 by aligning the two bolt holes 26 and 27 and then fastening them with a bolt nut 28. Furthermore, bolt holes 29 for connecting the arms 17 are formed at both ends of the receiving bracket 16, and the bolt holes 30 formed on the arm 17 side are matched with the bolt holes 29, and then fastened by bolt nuts 31. , Bracket on the receiving bracket 16
17 are connected.

[0006]

In the above-mentioned conventional configuration, for example, when the arms 17 are the long frame shelves 10, the operation of connecting the arms 17 to the receiving bracket 16 with the bolts and nuts 31 for the convenience of production and transportation. Will take place locally. At that time, since the inner diameters of the bolt holes 29, 30 are formed to be slightly larger than the bolt diameter, rattling is likely to occur at the time of fastening, and as a result, the arm 17 is loose when the load 20 is supported. The end side inclines downward and the load-bearing posture becomes unstable.

An object of the present invention is to provide a frame shelf having a fastening portion which can be fastened firmly without rattling and can be easily assembled on site.

[0008]

In order to achieve the above-mentioned object, a frame shelf having a fastening portion of the present invention has a first member and a second member for connecting a pair of members constituting the frame shelf. Along with forming the bolt holes, at least one of the bolt holes has a peripheral edge formed on an outwardly projecting edge, and a head of the bolt that can be inserted between both bolt holes and a nut that can be screwed into the bolt are Taper portions that can freely contact the end faces of the projecting edge portions are formed on the surface sides facing each other.

[0009]

According to the structure of the present invention, in order to connect the pair of members, the bolt is passed through both the matched bolt holes, and the nut is screwed to the projecting end of the bolt.
Then, as the nut is tightened, one of the tapered parts formed on the bolt head and the nut comes into contact with the edge of the bolt hole from the outside, deforms this edge in the fastening direction, and the other tapered part projects. It will come into contact with the end face of the edge,
Thus, the bolt and the nut are fastened to both members and at the same time, integrated with each other without rattling.
