Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shelf installed in a factory, for example, for loading and unloading cargo with a forklift truck, and a structure for connecting shelves in an automated warehouse.

2. Description of the Related Art Forklift trucks and shelves to which loads are loaded and unloaded by automated loading and unloading equipment in automated warehouses are fixed, for example, as shown in FIG. The right and left columns 81 are connected by a horizontal beam 84 and assembled. Arms 85 protrude from the left and right columns 81 at opposing positions, and arm rails 86 for supporting loads 87 are attached between the front and rear arms 85.

In this shelf, the arm 85 is fixed by welding to the side surface of the rectangular column 81 in the manufacturing plant, and the arm rail 76 is also attached to the tip of the arm 85 by welding to assemble the shelf and installed by truck or the like. Had been transported to the site.

Problems to be Solved by the Invention The shelves assembled as described above have a large volume, and there is a problem that the transportation cost becomes large, especially in the case of transportation in a remote place. In addition, the welding work in the manufacturing factory deteriorates the working environment such as air pollution, light and sound.

The present invention solves the above-mentioned problems, and provides a connection structure of a frame shelf that can be transported to an installation site in parts unit and easily assembled at the site, and furthermore, the welding environment is extremely reduced and the working environment can be improved. The purpose is to do.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention is to provide a erected pillar at least at four corners, protruding arms at the opposing positions of the left and right pillars toward the left and right pillars, respectively, In a connection structure of a frame shelf in which arm rails capable of supporting a load are arranged therebetween, a strut is formed in a straight shape having an outer plate portion and left and right side plate portions, and the strut is near the outer plate portion or the outer plate portion. A connecting member having a front plate portion and a side plate portion that can be freely applied to the outer plate portion and the side plate portion of the column, and a brace member fixed to the side plate portion. An engaging claw that is configured to be insertable into the engaging hole on the inner surface of the connecting member, and that the distal end portion can contact the inner surface of the outer plate portion when the plate portion and the side plate portion are applied to the support column. Arm, which is attached to the front and rear struts, The arm rail is connected between the front and rear arms in a state where the ends of the arms are turned to the side approaching each other around the abutting portion and the engaging claws are brought into contact with the inner surface of the outer plate portion to prevent rotation. It is configured so that

In the above-described configuration, the locking claws of the connecting member are inserted into the engaging holes of the pillars standing up and down, and the arm plate is rotated on a horizontal plane, so that the front plate portion and the side plate portion of the connecting member are connected to the outer plate portion of the pillar. The locking claw is fixed to the side plate part, the locking claw is brought into contact with the inner surface of the outer plate part to prevent rotation, and further, the locking claw is fixed to the brace while rotating to the other brace side, so that the locking claw is released. It is pressed against the inner surface of the plate. As a result, even if there is a dimensional error at the time of manufacturing of the strut or the connecting member, the locking claw is attached to the inner surface of the outer plate part by using the principle of "lever" with this abutment as a fulcrum and the elasticity of the arm tree. Due to the pressure contact, the arm and the arm rail can be firmly fixed to the support via the connecting member without looseness, and can be easily assembled at the installation site.

Numeral 65 is an adjusting tool for adjusting the level. A nut member 67 fixed to the lower surface of the base plate 61 corresponding to the through hole 66 formed in the base plate 61, a fixing plate 68, and the fixing plate 68 are rotatably mounted on the fixing plate 68. The fixing plate 68 is fixed by screwing the fixing bolt 71 to the floor 72 by engaging the fixing bolt 71 with the notch hole 70 and screwing the fixing bolt 71 to the floor 72. This adjustment tool
Numeral 65 is provided for an automatic warehouse or the like that requires level adjustment of the arm rail 9. If this adjustment tool 65 is not provided, the fifth
As shown in the figure, a fixing notch 73 is formed in the base plate 61, and the fixing notch 73 is directly attached to the floor 72 with the fixing bolt 74.

According to the above embodiment, the front and rear columns 2 can be easily connected by inserting the ends of the horizontal member 3 and the diagonal member 4 between the connecting plate portions 26 provided on the column 2 and fixing them by the rivets 27. Can be fixed. Also, the engaging claws 35A, 35B protruding from the connecting member 7 of the arm 6 are inserted into the engaging holes 31A, 31B formed in the front plate 21 of the support 2, and the front plate 32 and the side plate of the connecting member 7 are inserted. The portions 33 are respectively applied to the front plate portion 21 and the side plate portion 23 of the column 2, and the front end locking portions 35 a of the engaging claws 35 A, 35 B are attached to the reinforcing groove portions.
The arm 2 is brought into contact with the back of the bottom 25a of the arm 25, and the arm rail 9 is fitted to the tip of the arm member 8 attached to the front and rear struts 2 and connected and fixed by the rivets 36 to thereby fix the strut 2
The arm 6 and the arm rail 9 can be easily attached to the arm. Further, the side plate 62 of the seating member 12 is
The seat member 12 can be easily attached to the lower end of the column 2 by fitting it to the end of the front plate 62 and connecting it with the rivet 64. Therefore, the shelf 1 can be easily assembled by the installation phenomenon, and can be transported in parts, so that the transportation cost can be greatly reduced.

In the above embodiment, the rivets 27, 46, and 64 are used as the connecting tools, but bolts and nuts may be used.

Advantageous Effects of the Invention As described above, according to the present invention, the engaging claws of the connecting member are inserted into the engaging holes of the upright front and rear columns from the front or rear side, and the arms are moved in the direction in which the tip approaches in a horizontal plane. The front plate and the side plate of the connecting member are brought into contact with the outer plate and the side plate of the column, and the locking claws are brought into contact with the inner surface of the support plate to stop the rotation. By connecting the arm rail between the arms, the locking claw is strongly pressed against the inner surface of the outer plate part by utilizing the elasticity of the arm tree and the "leverage principle" using the abutment portion as a fulcrum. Therefore, even if there is a manufacturing error, there is no backlash at the connecting portion between the post and the brace and the brace rail, and the brace and the brace rail can be firmly fixed to the support. Errors can be tolerated. Therefore, the shelves can be transported in parts, and the transportation cost can be reduced and the welding operation can be omitted. Further, since the assembly is performed in this manner, the welding work can be reduced, and the working environment can be improved.
